The ESCB and the Eurosystem
The European System of Central Banks (ESCB) established under the Treaty on European Union (TEU) is made up of the European Central Bank (ECB) and the national central banks of all the Member States of the European Union (EU), regardless of whether or not they have adopted the euro.
The Eurosystem, in turn, groups together the ECB and the national central banks of the Member States whose currency is the euro.
Therefore, as long as there are Member States that have not adopted the euro, the distinction between the Eurosystem and the ESCB will be maintained.
The ECB, a supranational organisation with an independent legal status under international public law, constitutes the core of the Eurosystem and the ESCB.
The ECB was created on 1 June 1998 in Frankfurt and since then, has performed the functions of the European Monetary Institute (EMI). Since 1 January 1999, it has been responsible for implementing the euro area's monetary policy.
The national central banks
The national central banks have independent legal status under the national legislation of their respective countries.
The national central banks of the euro area make up the Eurosystem and, as such, perform the duties entrusted to them according to the regulations established by the ECB.
The national central banks can also perform other duties outside the Eurosystem independently, providing the Governing Council does not consider that these activities interfere with the tasks and objectives of the Eurosystem.


What Are The Cores Revealing: Week 2 Science
The main objective of our core sampling was to characterize the eruptive history of Montserrat back to the early beginnings of this island (~2.6 million years ago), based on the marine sediments and tephra (pyroclastic deposits from explosive volcanism) layers cored at this site. During week 2 of Expedition 340 we finished our drilling operations around the island of Montserrat. A total of 8 holes were cored and over 120 cores recovered. The deepest cores were obtained from ~245 meters below the seafloor. The following are science results as summarized by 340 Staff Scientist, Nicole Stroncik.
Generally, the material retrieved at both sites U1394 and U1395 consists of various combinations of hemipelagic muds, volcaniclastic turbidites of varying grain sizes and muds, and volcanic tephra. The background sediment mainly consists of fine-grained calcareous biogenic fragments (corals, shells, sponge spicules and critter skeletons) and siliciclastic sediment of pale yellowish gray to dark gray color, varying in grain size from fine silt to fine mud. The turbiditic units generally consist of a mixture of volcaniclastic and bioclastic material. Volcaniclasts include fragments of fresh andesitic lava, altered lava, and crystals (feldspar, amphibole, etc.). Bioclasts include fragments of carbonate materials such as corals and shells.
At Site U1396 we recovered a full record of hemipelagic sediments with intercalated tephra layers down to a total depth of 139 meters below seafloor. The hemipelagic sediments consist of a mixture of mainly carbonates and volcaniclastic particles. The tephra layers consist of mainly ash and pumice. Based on the bio-stratigraphic and magneto-stratigraphic studies done on the sampled material the deepest sediments cored at this site date as far back as 4.5 Million Years Ago (My). Most exciting is that with the large number of tephra layers retrieved within the cores it will be possible for the first time to completely reconstruct the geochemical evolution and the eruptive history of Montserrat, achieving all of the scientific objectives for this site.


Armadillo Facts – 46 Interesting Facts About Armadillo
Armadillo facts: Interesting facts about Armadillos. Armadillos are like mammals and give birth to young ones and wean them with milk like any other mammals. However their body has been adapted to their surroundings in the process of evolution. They are special because of the fact that they have an outer shell like covering much akin to tortoise. Their body temperatures are also unique to make them as good specimens for research. The most remarkable feature of this species is the ability of females to postpone their pregnancy if the surrounding environment is not conducive. This is something not seen much in the animal kingdom but for a few. The animal originated in South America and remained land locked and isolated for a major part of time before the formation of the Isthmus of Panama in the early Pleistocene which enabled them to migrate to North America.
Armadillo are barrel shaped animals who have a natural armor for protection.
The word Armadillo is a Spanish word which means “little armored one”
The armor is effective against most of its enemies but not the vehicles of modern day and frequently gets run over by automobiles.
There are more than 21 species of armadillo from as tiny as 6 inches, the Pink Fairy Armadillo to giant ones which can measure 1.5 meters
The armadillo armor is made up of overlapping plates covering the back, head, legs and tail.
Different species are identified by the number of scales they have on their body.
The three banded armadillo rolls itself into a ball to escape from predators.
Other armadillo dug themselves in soil and expose only their armor and protect their tender stomach.
Armadillo and Anteaters are cousins and both have pointed nose and sticky tongue.
Armadillo eye sight is weak but they are good hunters due to their well developed sense of smell.


In a stunning display of nature’s power, Popocatépetl volcano near Mexico City has erupted, sending plumes of ash and smoke into the sky. As Mexico raises the alert level, residents and authorities are on edge, closely monitoring the situation.
Mexico on high alert
According to Bloomberg, Mexican authorities have raised the alert level for Popocatépetl volcano, acknowledging its heightened activity and potential risks. The volcano, with its towering presence and ominous rumblings, serves as a reminder of the volatile nature of our planet. Scientists, alongside emergency response teams, are working diligently to ensure the safety of nearby communities.
In the wake of Popocatépetl’s eruption, Mexico’s Puebla Airport has taken swift action to halt flights due to the falling volcanic ash, as reported by Reuters. The safety of passengers and crew is paramount, and this precautionary measure aims to prevent potential hazards associated with volcanic ash, such as reduced visibility and damage to aircraft engines. Travelers are advised to check with airlines for updates and alternative arrangements.
Fascinating Facts about Popocatépetl
Popocatépetl is not just a volcano; it is an integral part of Mexico’s cultural and geographical landscape. Referred to as “Popo” by the locals, this iconic volcano has a rich history dating back thousands of years. Standing at an impressive height of over 17,800 feet, it holds a prominent place in Mexican folklore and has been an inspiration for countless legends.
Popocatépetl’s fiery eruptions serve as a stark reminder of the raw power of nature. While it demands respect and caution, this volcanic activity also draws awe and admiration from onlookers worldwide. Its majestic presence against the Mexican skyline serves as a poignant reminder of the forces that shape our planet.
As Popocatépetl continues to make its presence known, Mexico remains on high alert, closely monitoring the volcano’s activity. The eruption serves as a vivid reminder of the ever-changing nature of our world and the need for constant vigilance.For Image credit or remove please email for immediate removal - email@example.com


The name Sir Walter Raleigh will forever be associated with Elizabeth I and the first Elizabethan era when great fame and fortune came readily to England’s Virgin Queen. It was a time of great discoveries and of worldliness that Sir Walter contributed to.
Sir Walter Raleigh – poet, writer, soldier, courtier and explorer – is today recognised as one of the 100 most important people in England’s history.
A portrait of Raleigh with his son in a similar pose to the Doulton figure.
Hailing from Devon, he was a favourite of Elizabeth I at one time and was knighted by her in 1585. He was instrumental in the colonisation of North America and his explorations to Virginia paved the way for future English settlements there.
One of Doulton’s famous character hugs to the great man.
There has even been a Doulton Bunnykins made of Raleigh.
Whilst his story is a famous one, inspiration for this true to life study of him by Royal Doulton derives from a popular source of early Doulton figures, Dion Clayton Calthrop’s book on English Costume from the early 20th Century. He appears to have been modelled on the illustration shown with minor changes including the ruff around his neck.

The suspension conveying chain system is an important component in the coating production line. It is responsible for conveying the products to different process points for surface treatment.Conveyor usually adopts the overhead, but the freedom to choose air route, effective use of space, mainly by the chain track, stents, turning and lifting orbit, driving device, tension adjusting device, lubricating device such as part of the combination. Specific instructions are as follows:
1. Chain: the suspension conveyor line is transferred by the chain in the orbit, and the hoisting tool is combined with the chain to be responsible for the load task.The structure is: each pitch has a longitudinal roller, bearing the roller bearing of the load bearing, to reduce the friction resistance in the migration process.
2. Track: a unit of guiding chain, lower, left and right, with steel plate forming.
3. support: most rail bracket is divided into two kinds: one is light load, namely from under the floor slab suspending method, the other is a burden reuse, that is the pillar method, two methods are made of Angle steel and channel steel.
4. Turning and lifting track: the suspension conveyor line is also called the universal chain conveyor, so the turning and lifting of the direction should be coordinated by the horizontal elbow and the lifting elbow.
5. Driving device: it is a combination of three-phase ac motor, worm gear reducer, transmission chain tension regulator, driving chain wheel, shear pin and transmission caterpillar chain for caterpillar driving mode.
6, tension adjustment device: because of the chain when the load nature under the hammer, the season of elongation, consumption for continuous smooth running, must set tension adjusting device absorbing chain elongation, this device will typically have a heavy hammer type, screw and spring type three ways, using a sliding rail mounted on each other can be motivated box, with a heavy hammer, screw, spring to slip and achieve the purpose of regulating the chain slack.
7, lubrication device: the chain long running friction will increase, in order to avoid resistance is too large, resulting in chain is jammed, you need to set the refueling, can match the automatic tankers fixed-point spray into the high temperature chain oil, to ensure that the chain work in good lubrication condition.

Sarcocystis spp. are cyst forming apicomplexan parasites that infect many vertebrates including birds. Sarcocystis spp. infection was investigated in tissue samples (pectoral muscles, heart, and brain) of 47 dead seabirds collected from the coastline of Santa Catarina State SC - Brazil, between August 2019 and March 2020. A portion of each tissue was fixed in 10% buffered formalin for histopathologic analysis while DNA was extracted from another portion and screened using nested-PCR targeting ITS1. Based on molecular analysis, Sarcocystis spp. were identified in 15/47 (31.9%) seabirds of five species, kelp gull (Larus dominicanus), manx shearwater (Puffinus puffinus), neotropic cormorant (Phalacrocorax brasilianus), brown booby (Sula leucogaster) and great skua (Stercorarius skua). Microscopically visible sarcocysts were observed only in the pectoral muscle of four seabirds 8.5% (4/47), while in one brown booby, sarcocysts were seen in both pectoral and cardiac muscles. Two types of sarcocysts, thin walled (≤1 μm) and thick-walled (≥ 2 μm) were identified. Based on ITS1 sequence comparison, S. halieti, S. falcatula and three not yet described Sarcocystis spp. were detected. Phylogenetically, S. falcatula isolates were classified as two distinct clusters. This is the first confirmation of S. halieti in seabird's species in South America and S. falcatula in birds of the order Charadriiformes. Further molecular studies are needed to understand the epidemiology of the Sarcocystis spp. infection and its impact on the health of seabirds.

Preserving the Harvest
October 5, 2022
It’s the height of harvest season which means an abundance of produce! Sometimes, a large harvest can result in food waste when not planned correctly. If you don’t know what to do with your harvest, try canning!
Food preservation, like canning, has been around for centuries and it wasn’t too long ago that these methods were common knowledge. Most home canning involves a method called water bath canning. Supplies needed include a large pot, canning rack, unused mason jars, a jar lifter, and a funnel. Here are the basic steps:
- Boil the jars in water to sanitize them before filling them with produce.
- Once sanitized, fill a hot jar with prepared food (following a trusted canning recipe) using your funnel and make sure to leave some space.
- Wipe the rim and seal your jars with the lids, twisting the band securely.
- Place the jars onto a rack in a pot with simmering water, covering the jars with at least 1 inch of water. Boil jars according to your recipe (add more minutes for higher altitudes).
- Turn off the heat and let the jars sit for 5 minutes. Then, take the jars out and let them cool for a day.
- Check to make sure your jars are sealed properly!
Home canning is a great way to eat local all year long while also reducing food waste. Other great food preservation methods include pickling and canning. Check out USUS Extension’s Food Preservation Resources for more info at https://extension.usu.edu/preserve-the-harvest/canning !


For those of you who like floor gymnastics, of course you are no stranger to “Cartwheel”.
Cartwheel is also called a movement that relies on both hands like a headstand. Cartwheel aims to create a cartwheel that relies on both hands.
The difference between Headstand and Cartwheel can be seen from how to do it and the form of the movement.
Headstand is done by lifting both legs up, then resting on both hands and then maintaining body balance.
Unlike the Cartwheel which aims to do wheel rotation and land using the feet.
You can do the Cartwheel movement anywhere, including at home. Because to do this movement, you only need a room that is not too wide.
How to Do a Cartwheel at Home
- First you have to determine a safe place to do the Cartwheel movement.
- Next, provide a small mattress or mattress as a base
- Determine the direction of rotation to do the cartwheel and pay attention to the surrounding area
- To do a Cartwheel, raise both arms up and point them in the direction while turning your body like a wheel while preparing to lift one leg and the other leg to hold.
- Make a circular motion to form a wheel
- When the body turns, prepare the feet to land and the body is perpendicular again as it was at the beginning of the movement.
- Don’t forget before doing Cartwheel, you have to be really prepared to avoid injury.
- Help maintain a healthy body
- Makes muscles strong
- Bones become strong
- Burn calories in the body
- Body balance training
That is an explanation of the Cartwheel or wheeling movement in this article. Hopefully it can add to your knowledge and be useful for all of you.

It's nearly time for a new school year to begin which means it's time for the inevitable placement auditions. Just a thought for students and teachers alike: 1. Success is a fraction of failure. Musicians tend to put a lot of pressure on single audition (which will almost invariably cause more stress)which can have a negative effect on the final outcome. If a baseball player has a 300 batting average, this means he is failing 7 out of 10 times...and a 300 average is GOOD in baseball...very good in fact. We need to remember that each "less than optimal" outcome is leading us thru the road to success. Nobody remembers all the auditions they took and lost...it only takes winning ONE great audition to secure the professional job (or goal of first chair, etc). Stay process oriented...(enjoy the journey) rather than becoming outcome oriented (a total fixation on the desired goal). If you enjoy the journey, you are sure to arrive at the destination in style.
Singing and Playing
Singing and playing at the same time is a contemporary effect that has become common in 20th and 21st century literature, but it can also be used as a very helpful exercise! Try singing a note, while playing the major chord from that bass note in an arpeggiated fashion. Notice that the larynx will remain still on this sustained note. This will help your playing by making you aware of movements of your larynx, (it will help you know what an open throat can feel like). You will also increase your support as you try this technique, and your focus should improve as well. Try this on BOTH flute and piccolo too...it will really help your tone!


Venus and Cupid (Primary Title)
Artemisia Gentileschi, Italian, 1593 - 1652 (Artist)
Artemisia Gentileschi, who trained in Rome with her father, Orazio, was the leading female artist of the 17th century. She worked mainly in Rome, Florence, and Naples. In 1616, she became the first female member of Florence’s noted Academy of Painting.
Gentileschi’s work, which is marked by the strong contrasts of light and dark as well as unusual, bold compositions, was influenced both by her father’s painting style and that of his famous associate, Michelangelo Merisi da Caravaggio. Her subject matter often consists of powerfully rendered portrayals of women – Judith, Susanna, Cleopatra, and Danäe, for example – dramatically depicted either as heroines or victims.
In this work, however, Gentileschi has created a sumptuous image of Venus, the Goddess of Love, asleep under a velvet hanging. Her bedcover is painted with ultramarine, an expensive pigment made from powdered lapis lazuli. Behind her, Cupid wields a peacock-feather fan to keep pests from annoying or waking her. At the left is a view of a mountainous landscape with a small circular temple, reminiscent of the one dedicated to Venus near Hadrian’s villa in Tivoli, just outside of Rome.

Ants are important in the world of plants. They eat plants and seeds, as well as decaying plant, fungus and animal material. They consume nectar and thereby pollinate flowers; they eat elaiosomes and thereby disperse seeds. They have been singled out in the Bible for the virtue of being hard-working.
Ants have been active on earth for longer than 100 million years. There are at least 12 000 ant species on earth. And there may be more as only a part of the insect world has yet been studied and described. Having been here for so long, the ants are biologically very diverse.
All ant species are social, i.e. there are no species of single living ants, as found for instance among bees. Ants are believed to have evolved from ancient wasps that nested in the ground. Within an ant species several castes (of sterile female ants) of different sizes and differently endowed, perform specialised functions in the complex systems characterising their colonies.
In 1948 Hutchinson and Melville wrote in The Story of Plants about humanity’s increasing control over its physical environment, foreseeing social and even physical evolution of people into dedicated working and controlling castes, resembling the organisation of ant colonies.
Whether human society will be more democratic or more totalitarian, governed in accordance with better or worse values, long term transformation continues steadily in the total biosphere of land, water and air that surrounds the earth. Human impact on earth is increasing for now, but is so far very short-lived, compared to that of the ants. And enormous insect generated effects (and benefits) still occur around us, including a large contribution from the ants.
All that lives on the earth collectively creates transient, multidimensional matrices or webs of successive ecologies. These ecologies or integrated living systems continually adapt interactively to something better for winners of the moment, worse for the losers; the eventual outcomes unknown for all.
Nature has no grand plan, only a complex process of continual becoming, in accordance with its constituent forces of the day. Evolution is an open-ended process, the species yet to come will also have their surprises (Holm, 2008; http://harvardforest.fas.harvard.edu).


7.2. Definitions of Nepalbhasa Terms
- Nepal : An independent sovereign country located in between China in the north and India in the south.
- Nepal Mandala : A historical area demarcated as the co-federation of original Nepal before it was fully occupied by the Gorkha army since 1769 AD.
- Nepalbhasa : Bhasa refers to language. Hence Nepalbhasa here means the language of Nepal. Nepalbhasa originated in this land. It has been the State language of Nepal until it was replaced in 1960s by Nepali, a name usurped from Nepalbhasa to Khas language of the present rulers.
- Nepal-lipi : Lipi refers to script or letters. The script originated in Nepal is called Nepal-lipi. It was primarily used to write Nepalbhasa while several other languages such as Sanskrut, Pali, Maithili and Khas languages were also written in Nepal-lipi in the past.
- Nepal Samvat : Samvat refers to calendar. Nepal Samvat here means the calendar originated in Nepal. It is formally known as Nepal Samvat Naguma (Nepal Era calendar) but shortened as NS.


A direct hit from a powerful solar flare is one of the most destructive events that could befall our planet.
In fact, the devastation could be unimaginable. A 2008 National Academy of Sciences study estimated the potential impact to the US economy at almost three trillion dollars.
But, beyond the dollar impact to our economy, the human toll would be even greater – with power outages lasting months (or years) the resulting breakdown of basic services would plunge our society back into the dark ages.
Now it’s revealed the U.S. Government is making plans for the possibility of a massive solar flare directly impacting the United States.
The last major solar event was in 1859. It was so powerful that it burned out telegraph lines, caused telegraph offices to catch fire and knocked out power through the northern hemisphere.
Given how much more dependent our society is on technology, the results of a similar event today, would be countless times more devastating than 150 years ago.
While solar flares cannot be predicted with any precision, scientists estimate at least a 12% chance of a major impact within the next five years and believe that it’s not a matter of “if” a solar flare event occurs, but “when” it will occur. (In fact, just three years ago we had a very near miss with a powerful solar flare that would have had a devastating effect on all of us.)
With the strong likelihood of a major solar event striking within the next few years, the need for prepping and planning is more important than ever!

To assess U.S. water resources, the U.S. Geological Survey (USGS) divides the nation into 22 hydrologic regions, or watersheds, based on the flow of water throughout the country. Each watershed represents a major river drainage area (e.g., the Missouri region) or combines rivers’ drainage areas (e.g., the Texas-Gulf region which includes several rivers draining into the Gulf of Mexico).
Even locations that are far from bodies of water are part of a hydrologic region because chemicals released to groundwater, land, or air can be washed or carried long distances to surface waters. These discharges can affect living resources within an aquatic ecosystem. For example, some chemicals can persist in the environment and accumulate in the tissues of fish and other wildlife. These chemicals can become more concentrated as predators farther up the food chain eat these organisms, which may ultimately cause health problems for wildlife and humans.
All 22 watersheds are displayed in the Where You Live map. The chart below shows the ten watersheds with the most TRI chemical releases for 2021. Releases were the greatest in the Alaskan and Great Basin regions. In these regions, most releases were from metal mines.
Note: Chart shows the ten watersheds with the most TRI chemical releases in pounds.
The chart below shows the ten watersheds with the most TRI chemical releases per square mile. Releases per square mile are greatest in the Great Basin region, which encompasses much of Nevada and Utah. Releases from metal mines make up 91% of the releases in this region.

This study confirms that liver disease is growing rapidly among men, women and young adults. The increase in the rates of liver disease among older adults is attributable to alcohol abuse, hepatitis c, and non-alcoholic fatty liver disease. Surprisingly, younger adults are also experiencing rapid increases in liver cirrhosis, which is attributed to binge drinking and other forms of alcohol abuse.
Study: Alcohol Fuels Drastic Increase in Liver Disease
A new study found that cirrhosis-related deaths increased the most among people aged 25 to 34 from 2009 to 2016.
By Alexa Lardieri, Staff Writer July 20, 2018, at 1:39 p.m.
U.S. News & World Report
Alcohol Fuels Cirrhosis-Related Deaths
DEATHS FROM LIVER disease, especially among young people, have increased dramatically since 1999, according to new research.
A study published Wednesday in The BMJ examined deaths related to cirrhosis and liver cancer from 1999 to 2016. Researchers discovered that cirrhosis-related deaths increased 65 percent among men and women across all ethnicities, totaling 34,174. Deaths from liver cancer doubled to 11,073. Asians and Pacific Islanders was the only subgroup that saw a decrease in mortality from cancer.
According to the study, from 2009 to 2016, “the period of worsening death rates,” people aged 25 to 34 experienced the highest annual increase in cirrhosis-related deaths (10.5 percent), which was entirely fueled by alcohol-related liver disease. The researchers stated this finding is “reinforced by parallel changes in mortality due to alcohol use disorders and all alcohol-related liver disease.”
The study found men experienced twice as many deaths from cirrhosis as women. (GETTY IMAGES)

Physical Touch is one of the five love languages identified by Dr. Gary Chapman. It involves expressing love and affection through physical touch, such as hugs, kisses, holding hands, and other forms of non-sexual physical contact. People who speak this love language feel most loved and appreciated when their partner shows affection through physical touch.
Physical Touch can take many forms, such as:
Hugs and cuddles: This can include embracing your partner and cuddling up on the couch.
Holding hands: This can include holding hands while walking or sitting together.
Touching: This can include touching your partner’s arm or back when you’re talking to them or giving them a gentle pat on the back.
Massage: This can include giving your partner a massage or receiving a massage from them.
Sexual intimacy: This can include sexual activity, but it’s important to note that Physical Touch does not necessarily equate to sexual activity.
Physical Touch is an important love language because it can help create feelings of comfort, safety, and closeness. When you express your love through physical touch, it can help your partner feel seen, heard, and valued. However, it’s important to note that Physical Touch should always be consensual and respectful of boundaries.


In a field one summer's day a Grasshopper was hopping about, chirping and singing to its heart's content. An Ant passed by, bearing along with great toil an ear of corn he was taking to the nest.
"Why not come and chat with me," said the Grasshopper, "instead of toiling and moiling in that way?"
"I am helping to lay up food for the winter," said the Ant, "and recommend you to do the same."
"Why bother about winter?" said the Grasshopper; "we have got plenty of food at present."
But the Ant went on its way and continued its toil.
When the winter came the Grasshopper had no food and found itself dying of hunger, while it saw the ants distributing every day corn and grain from the stores they had collected in the summer.
Then the Grasshopper knew: It is best to prepare for the days of necessity.

Solid-solution distribution of the cosmogenic beryllium-7 in the water column
This work questions the validity and limits of the hypothesis that particulate beryllium-7 (7Bep) can be neglected in the different oceanographic applications of this tracer. To tackle this issue, Grenier and co-authors (2023, see reference below) measured the 7Be activity in suspended particles collected in and below the mixed layer in oceanic regions as different as the Mediterranean Sea, the Southern Ocean and the subpolar Atlantic (section GEOVIDE/GEOTRACES-GA01). While the 7Bep activity generally monotonically decreases with depth below the mixed layer, they reveal that, at least in some oceanic regions, the removal of 7Be by marine particles may be significant. The 7Bep fraction ranges from 2% to 32% of the total 7Be activity along the GEOVIDE section in the North Atlantic. In the Labrador Sea, the comparison of the 7Bep inventories with the dry 7Be deposition fluxes estimated from aerosol samples collected during GEOVIDE suggest that a significant portion of 7Bep may be removed by sinking particles. The authors conclude that future research should focus on quantifying the downward export of 7Bep to deep waters, and on assessing its temporal and spatial variability. They strongly recommend that future sampling programmes should aim to collect seawater and particulate samples at the same locations, at the same depths, and at the same time.

There are many factors that affect the use of the hydraulic hose assembly. The reliability and economy of the hose can only be guaranteed if the hose and fitting are correctly selected according to the working conditions.
1 hose inner diameter
If the pipe diameter is too small, the flow rate of the medium in the pipeline will be increased, the system will be heated, the efficiency will be reduced, and an excessive pressure drop will be generated, which will affect the performance of the entire system.
2 working pressure
The highest pressure allowed by the hose during continuous operation.
The recommended working pressure is typically one quarter of the minimum burst pressure of the hose.
Different configurations of hoses have different working pressures.
3 Impact pressure and fatigue life
Determined based on the highest pressure value of the hydraulic system design.
The peak value of the impact pressure will be much higher than the highest pressure value of the system. but
There are generally overflow valves on the system, so the impact pressure will not seriously affect the hose.
For hydraulic systems with particularly high impact pressure, it is recommended to use a special pulsation-resistant shock.
4 temperature range
The user should use the hose within the temperature range allowed by the hose quality specification. If the working environment temperature exceeds this range, it will affect the life of the hose, and its pressure bearing capacity will be greatly reduced. A hose jacket is recommended for systems where the operating ambient temperature is too high or too low.
5 Chemical compatibility
If special hydraulic media is used, the user should ensure that the hose assembly selected and its hose inner, outer, joint and O-ring are compatible with the media.


A Statute of Limitations refers to the period of time in which a lawsuit must be commenced, before it is "too late" and untimely. In a personal injury case, this period of time is usually computed starting with the day of the accident.
The Statute of Limitations is not the same for every type of case. For example, the typical New York personal injury case based on negligence must be commenced within 3 years from the date of the accident. But New York personal injury cases based on medical malpractice have a 2.5 year statute of limitations. Claims for wrongful death have a 2 year statute of limitations from the date of the fatality.
The status of the parties also affects how the time period is computed. For example:
- An injured person under the age of 18 generally reckons the Statute of Limitations from the time he or she turns 18 -- and not from the date of the accident.
- When the defendant is a governmental entity, such as a municipality, the State or Federal government, or an agency, the time within which to commence the lawsuit is much shorter, and typically requires a formal Notices of Claim, or other prerequisite to the lawsuit.
One of the first things we will do in representing you in a personal injury claim is to determine exactly what type of case you have, and what the statute of limitations is for you and your particular case.

Special session for children – Art handling: study and manipulation
- Stimulate fine handling and creativity
- Know the handling natural material
- Know the shape
- Approach to three-dimension manipulation.
The objective of the proposal is the achievement of the creativity autonomy in the fine handling. During the five meetings, children will be encouraged to handle materials of natural origins. The material used will be clay, salt dough. Starting from the classic production of the salt dough, will be handle the end product and create a work with the clay.
Meeting 1 – Dough
Children will be guided towards the transformation of three elements such us flour, water and salt in the ‘modeling salt dough’; material that probably is already well-known as end products. The aim of the meeting is to transformed and experiment dough. Free manipulation.
Meeting 2 – Shapes
During the workshop, children will handle the dough in a guide manner. With the help of recognizable and simple shapes, they can realize the material ductility and the various possibility in handling. Guided manipulation in the shapes creation.
Meeting 3 – Clay
During the workshop will be presented a new material: the clay. Will be provided experimental examples with the help of natural clay clods (it would be possible, to be agreed, to search clayey soils in the countryside). Free handling, study of the differences between clay and dough.
Meeting 4 – Pushing
Even if banal, pulling clay process has specific rules. Children will experience different ways to obtain a workable dough layer. Through the use of rolling pins and splints, children will rolling one or more layers to use as bases of work.
Meeting 5 – Dimension
Observation and study of three-dimensional shapes/forms and production of simple forms already know by children. Possible links with other subject areas: Art, Nature, Science, Nutrition.
Every meeting takes about 50-60 minutes according to the age of the students. All materials are included in the offer. The itinerary is organized and designated for children of I-II-III grades of nursery school.nursery school

Access 2010 is a powerful Database application that allows users to produce tables, forms, queries and reports within a database it can also contain calculations, graphs, pictures and files. This ebook is the second part of a series of four ebooks. In the first part Access 2010: Learn Access you found an introduction to Access 2010. In this part you will learn how to create tables and queries.
Tables are the main objects used in databases. (Without tables, and thus without data, you don’t have much of a database!) In Access 2010: Part I you learned that a table contains one or more records (or rows of data) and a record contains one or more fields. In this ebook you will go a step further and learn much more about the usage of tables, including how to build them from scratch. Further you will learn how to set field properties, create lookup fields and relate tables.
A query is a question that is asked of a database control program about the data it contains. We specify what particular fields we are interested in finding out, tell the database where to look for those fields, and specify any conditions under which to search. In this ebook you will learn to understand the use of queries, to use the query wizard and to build basic queries in Query design. Furthermore you will learn more about applying criteria and building calculations.
On installation of Access, the installation of sample databases like Northwind is an option.


Tree syrup is produced by concentrating the sugars found naturally in sustainably harvested tree sap.
Freezing spring nights and warm spring days in North America play a pivotal role in its maple syrup production, by getting the sap flowing in big, old maple trees, which can then be collected and processed into syrup.
Aotearoa’s mild winters would seem to rule that out, but our climatic conditions are sufficient to enable maple sap flow. However, rather than focusing on old trees, we are examining the potential of young trees, in a closely spaced, horticultural-style row-crop, similar to an orchard or vineyard in approach.
Matching tree species to New Zealand conditions could allow an alternative, higher-value use for marginal land, support regional development, and produce an exportable product. We are building a business case for Tree Syrup Aotearoa.
Research is underway to explore this opportunity, and to de-risk investment into a new-to-New Zealand tree syrup industry.
Our team was recently awarded three years of research funding where we will be focusing on scientific evidence to describe tree-syrup sap exudation mechanisms. The initial focus is maple, but birch syrup has an even higher value, while syrup derived from native trees could enable a protected geographical indication (like scotch to Scotland) and further support a nationwide tree syrup industry.
We are using this website to share our research results, data and information, and to build a community of interested stakeholders for the exchange of ideas and experience.

Suffering from chronic shortness of breath? Beware, you may be at risk of a potential heart failure or COPD (Chronic Obstructive Pulmonary Disease), a study has found.Shortness of breath, which is medically known as dyspnea, is often defined as an intense tightening in the chest, air hunger or a feeling of suffocation. "Shortness of breath is often a sign of heart or lung disease because these two organs are most closely involved in the respiratory system," said Nasser Ahmadi, research student at University of Gothenburg in Sweden, in a statement. Chronic shortness of breath can also be considered as an equally important warning signal as high blood pressure, the researchers said.However, shortness of breath is an often overlooked symptom as people tend to associate it with ageing. "The fact that people do not seek medical advice for their breathlessness is often due to people associating their symptoms with the natural process of ageing. But if you notice that you experience increased shortness of breath during exertion, you should seek medical attention," Ahmadi added.The study showed that the faster the detection, the better prognosis. With early intervention, patients can avoid suffering and the need for hospitalisation decreases. In the study, people with shortness of breath for six weeks or more who sought medical advice for their breathlessness were found to have underlying diseases like a potential heart failure or a hidden obstructive lung disease that was developing.

Columbia University and Rijksmuseum Amsterdam present a lecture by Dr. Valika Smeulders about changing museum narratives in the Netherlands. This talk coincides with the Rijksmuseums exhibition ““Slavery. Ten True Stories of Dutch Colonial Slavery,” that will be featured at the UN from March 27 -30. Register for the event here.
February 24, 2023; 12:00pm -1:30pm EST.
Room 612, Schermerhorn Hall at Columbia University.
About the Lecture
In 2021, Rijksmuseum Amsterdam presented its first exhibition on slavery, freedom and the significance of the colonial past for our present. At its announcement in 2017 the exhibition was seen as highly controversial. This year, the Netherlands is commemorating 160 years of abolition. The commemoration was set in motion with an official apology by the Dutch state for its involvement in the colonial system. How are museum narratives changing in the Netherlands, and what is next on our agenda?
About the Speaker
Dr. Valika Smeulders is head of the Department of History of the Rijksmuseum in Amsterdam. She specializes in the colonial past and its representation, museum collections, their social relevance, and restitution policy. She has published on the Dutch slavery past in the Netherlands, the Dutch Caribbean, Ghana, South Africa and on Caribbean heritage in Dutch museums. She was a member of the UNESCO Memory of the World Committee in the Netherlands, of the Dutch advisory commission on policy for colonial collections and is currently a member of the research commission for colonial heritage in the Dutch royal collections.


What is an Orthodontist?
Orthodontists are qualified dentists, who after graduating from dental school, go on to additional full-time education in an accredited orthodontic residency program supervised by orthodontists. That training lasts at least two academic yearssometimes more. By learning about tooth movement (orthodontics) and guidance of facial development (dentofacial orthopedics), orthodontists are the uniquely trained experts in dentistry to straighten teeth and align jaws.
Orthodontists diagnose, prevent and treat dental and facial irregularities. The majority of members of the American Association of Orthodontists (AAO) limit their practices to orthodontics and dentofacial orthopedics. Orthodontists treat a wide variety of malocclusions (improperly aligned teeth and/or jaws). They regularly treat young children, teens and adults.
Only orthodontists may be members of the American Association of Orthodontists (AAO). Creating beautiful smiles through orthodontics is our business.
What is a Board Certified Orthodontist?
Dr. Watterworth is Certified by the American Board of Orthodontics.
An orthodontist may choose to become Certified by The American Board of Orthodontics (ABO). Involvement in the certification process is OPTIONAL and a demonstration of the orthodontist’s pursuit of continued proficiency and excellence.
The certification process involves a thorough Written Examination covering all areas of information on which an orthodontist should be knowledgeable. Successful passage allows the orthodontist to present treated cases which will be evaluated by expert examiners of the Board during a Clinical Examination. Certification is now awarded for a time-limited period and the orthodontist must re-examine on a periodic basis to retain the board certified status.

This document lists recommended practices for formatting and describing American Standard Code for Information Interchange (ASCII) encoded data files, such that the files will be self-describing and adhere to common conventions.
The ASCII File Format Guidelines for Earth science data was recommended for use in NASA Earth science data systems in 2016.
NASA Earth Science Community Recommendations for Use
These guidelines address a number of common-sense practices that can make data files encoded in ASCII more widely useful. The recommendations were developed by a community of users from NASA's ESDS community. The guidelines are meant to inform teams of basic practices that will provide for greater interoperability among systems that use data encoded in ASCII.
This document is meant to provide a checklist approach to be able to test whether a particular format meets the guidelines. As such, it is not possible to provide an exhaustive enumeration of practices that must be done or must be avoided.
This document provides a reference to determine whether ASCII data conventions developed by various Earth science communities meet minimum guidelines. Further, the guidelines in this document can inform creators and users of any ASCII-encoded data about whether their data files meet a minimum and necessary set of requirements.
The guidelines in this document were developed by a small group of ASCII data producers and consumers. It is likely that there are established ASCII data formats and practices in existence that are viable but don’t meet all of these guidelines.


The International Livestock Research Institute (ILRI) which co-leads A4NH work on Improving Human Health, has released a series of briefs on One Health which aim to highlight the benefits of the One Health approach for improving sustainable livestock production and strengthening livelihoods and improve our understanding of the complex linkages between the wider environment, animal and human health.
One Health approaches work across sectors and scales for better health outcomes for people, animals and the environment and recognizes the interconnections between all three.
The series of seven key messages and more than 20 practical action areas provide governments, investors, experts in One Health and policymakers options to invest in better health and improved food systems. The interventions emphasize the need to move to actions that are adaptive and flexible in local contexts.
The briefs explore:
A new proposed One Health initiative by CGIAR will work with farmers and governments around the world to improve food safety, disease surveillance, reduce AMR, protect the environment, and unite experts.
The authors share ten facts on India’s urban employment during the pandemic and the lockdown in this opinion piece which originally appeared in the Financial Express.
CGIAR researchers have conducted the first world-level assessment COVID-19's impacts on food security. Their findings also shed light on considerations for building back more resilient food systems.

Complete Set of 2 nos of postage stamps on the Historic Ships:
Issued by Japan
Issued on Apr 12, 1976
Issued for : As the 4th of the Ship Series two 50 yen postage stamps (se-tenant) will be released featuring “Taisei-maru” and “Tenyo-maru” respectively.
Picture : Taisei-maru was a large barque with 4 masts built in 1903 as navigation training boat attached to the Merchant Marine School (now University). The equipment of the boat was so perfect as to be matchless in the world in those days. It navigated more than 60 times covering more than 600,000 nautical miles in total with more than 4,000 students trained on board it before it sank down in 1945 knocked against a torpedo. It greatly contributed to the marine transportation of Japan. The gross tonnage was 2,287 tons.
Tenyo–maru: After the Russo-Japanese War (1904-5) the average gross tonnage of the English and American passenger ships on the Pacific line increased to 10,000 tons while that of Japanese liners was then 6,000 tons. Under the circumstances, to vie with the western liners the Tokyo Shipping Company built in 1908 the steamer gross tonnage of which was 13,454 tons able to carry 368 passengers. Fed with liquid fuel and equipped with wireless set for the first time in Japan, it had been in the service on the Pacific until it was dissolved in 1933. It was the excellent ship that represented the progress of the shipbuilding technical skill.

In recent years more and more parents have been renting bounce houses or having their child’s birthday or other party at an amusement facility where there are bounce houses. Children in Miami generally love these bounce houses, and certainly use up a lot of energy. But the reckless abandon that kids embrace all too often lead to injury. Current statistics indicated that an injury occurs in a bounce house once every 46 minutes, and many of those injuries can be serious such a spinal or brain injuries.
While it would be natural to advise parents and caregivers to follow established safety protocol when using these houses, the simple truth is there really aren’t firm guidelines in place. The high rate of bounce house accidents is giving many pediatricians and other medical experts a case of déjà vu, because it was only a few years ago when in home trampolines were causing similar concerns.
Injury by inflatable bouncers is nothing new, the National Electronic Injury Surveillance System database reported nearly 65,000 inflatable bouncer injuries between 1990 and 2010. The finding also identified a sharp increase in the injuries, with injuries occurring twice as often between 2008 – 2010.
While experts look to develop reasonable safety guidelines, the brunt of the responsibility for keeping a child safe lies with parents and their own common sense. Since studies show more injuries happen to younger children, and when children collide into one another, it is recommended that children under 6 years old not be allowed inside bounce houses. It is also preferred that only one child play in the house at a time. In cases where a second child does enter the house, both children should be close to the same age and size.
Chances are, the popularity of bounce houses is not going to deflate any time soon. It’s important to explain the dangers to both children that go in the houses, and the parents responsible for supervision.

Festival and Event
Like many other countries, Cambodia also celebrates on things for their meaningful stories, which may result national public holidays.
Cambodia Royal Ploughing
Khmer New Year Celebration
Khmer New Year, also known as "Choul Chnam Thmey," meaning entering the new year, is a national holiday hosted by Cambodians annually. It is the season when Cambodians have free time from harvesting rice and other agricultural commodities. The event is Cambodia's largest event and lasts three days, on the 13th, 14th, or 15th of April (in a specific year, it could be on the 14th to 16th of April).
Pchum Ben Day or Ancestor Day
Pchum Ben, also known as Ancestor's Day, is a half-month period (fifteen days: from one Roach to fifteen Roach) of remembrance for dead family members, which traditionally begins between September and October (the tenth month of the Khmer Calendar). Pchum Ben is believed to be a time when the souls of our ancestors that passed away may come back to us. The course of their journey will be decided by their karma and by the offerings made by their living relatives during Pchum Ben.
"Visak Bochea Day" is a day to commemorate the Buddha's birth, enlightenment, and death. It is a day to dedicate to his Dharma principles and adopt them into your everyday lives.This Cambodian public holiday is celebrated on the full moon of the sixth month of the Buddhist lunar calendar, which is usually in May on the Gregorian calendar.
Water and Moon Festival (Bon Om Tuk, Bondet Protit, Sam Peah Preah Khae)
The kingdom of Cambodia has a wealth of traditional and cultural festivals dated according to the Cambodian lunar calendar. All these festival are influenced by the concept of Buddhism, Hinduism, and royal cultures. The festivals, which serves as a source of great joy, merriment and Cambodian’s national colors, play a major role in influencing tourists’ opinions, behaviors, and options. Most of these are a time of replacing the predominantly urban and rural populace.


In the beginning of the Torah, the Torah describes various min - types or categories of animals. Each has a distinct definition - animals, birds, fish etc. The defining feature of all bird-like animals is that they fly and have wings. They come from the water but that's the definition. So if you find a winged creature that you don't know how to classify, you have to know if it flies and has wings. The question is really what animal has the potential to fly, and has wings - but doesn't - what is it's status. So an Ostrich is one such example. Then there is the duck-billed platypus that lays eggs is another example of an in-between species.
Rashi (Lev. 11:13) explicitly says that a single min includes various different species.
Acc. to Menachos 29a, it seems even Moshe Rabbeinu was not clear on which animal and species was what without prophetic help.
Often different types of animals share the same name because they have similar characteristics. (for example התנשמת) used in Lev. 11:18 and 11:30. See also Chulin 63a.
See also Rabbeinu Bachya Lev. 11:2 and Lev. 11:43 as well as the Malbim on Lev. 11:29.
So the Torah would easily consider bats to be birds for a number of reasons: 1. They both fly, and therefore can be considered to be under the same general category of winged-flying creatures. 2. They would have similar names for this reason. 3. We're not necessarily expert in the differences between animals and their names in the Torah, so it might well be that we're misunderstanding to which creature the name actually refers.


A regular expression is similar to a rule which defines the characters that can appear in an expression. In SQL databases, selecting field values based on regular expressions can be very useful. One example would be to validate credit card numbers or telephone numbers from a given database field. Another would be to check numeric values matching a particular sequence, such as integers containing the digits 99 or 88. SQL server database implementations provide built-in regular expression support.

A comparative study on bio-polishing of woven and knitted fabrics
Author(s): Tryphena R
‘Bio-polishing’ is considered to be an example of novel use of ‘biotechnology’. It is controlled hydrolysis of cellulosic fiber by the cellulose group of enzymes in order to improve surface appearance. The change, development and globalization of the world have brought up new notions and developments in the textile sector, in accordance with all the other sectors. The numbers of features expected from textile products has increased due to changes in the buyer’s expectations and their awareness of quality and environment. For example, pilling is one of the major undesirable and serious problems in apparel and the textile products. It does not cause an unsightly appearance or bad handle properties, but it has an accelerating effect on the rate of fiber removal from the yarn structure, and hence materially reduces the service life. Fabric pilling is a complex phenomenon and it’s comprised of different stages: yarn type construction, fabric type construction and fabric finishes play an important role in the pilling properties of fabrics. In this study woven and knitted fabrics were bio-polished and their results on pilling, color fastness to washing, light, rubbing and printing was studied.

Cultural practices are the biggest problem but also inadequate facilities of learning in school. Most of our schools, they don’t have skilled teachers on disabilities, there is no infrastructure which is accessible to children with disabilities, so parents they feel that there is no need of taking kids to school.
I know very well the challenges I faced in the education process, so after completing my studies I became interested in making sure that other people become aware of their rights, so that is why I am part of disability movement.
As the Programme Officer for SHIVIYAWATA, I organise sensitization meeting and activities, such as radio programmes, television programmes, and training on the rights of persons with disabilities.
Sensitisation is about raising awareness in the community on the importance of education for children with disabilities. We have different approaches, in most cases we organise community meetings on the street, we organise television and community radio programmes, we participate in commemoration days such as the International Day of Persons with Disabilities and Education Week. We participate by giving brochures, posters and other communication materials.
Most organisations they are not dealing with people with disabilities. Most of them engage with HIV, malaria, TB and other problems but on the issue of disability there are very few organisations, so what I can say is ADD International is a very important organisation in the disability movement in our country.
Millions of disabled children never go to school and are condemned to a future of poverty and exclusion. Right now, we’re partnering with disability activists to ensure that every disabled child gets access to a quality education.

Prior to the mid 20th century, houses and buildings were constructed in a manner that left them vulnerable to insect pest invasions, and this is why older structures see the highest rate of extensive infestations today. After the second World War, the pest control industry bloomed, and in an effort to reduce costly insect pest issues, housing authorities enacted regulations requiring homes to be built with insect-resistant structural features. For example, in order to reduce subterranean termite infestations, structural lumber and wood siding could no longer make contact with the ground soil. Although these regulations dramatically decreased urban and suburban insect pest infestation rates, modern homes remain prone to developing moisture issues, which attract a vast number of insect pests indoors.
Most modern homes contain hollow walls, or “wall voids,” that provide insect pests with an indoor refuge. There exists numerous indoor and outdoor entry points that provide insect pests with easy access into wall voids, including crawl spaces, foundation cracks, attic spaces, and gaps surrounding utility pipes and cables that enter homes from the outside. Rainwater, condensation from pipes, plumbing leaks, and water from bathtubs cause moisture to develop within wall voids, which creates ideal conditions for a majority of household insect pests, most notably cockroaches, termites, and numerous ant species.
Moisture in wall voids may lead to the growth of fungi, which serves as a food source for several insect pest species. In the northeast, insect pests such as stink bugs, Asian lady beetles, western conifer seed bugs, and boxelder bugs nestle into exterior cracks and crevices beneath siding and shingles, which lead directly to interior wall voids. These insects, along with cluster flies, also enter attic vents where wall voids are easily accessible to the pests. Termites, ants, bees and wasps also establish nests within wall voids, and in some cases, pest control professionals are not always able to eradicate heavy infestations in wall voids without removing drywall and insulation. Regularly inspecting a home for plumbing issues, rainwater leaks, gutter obstructions, and preventing rainwater from pooling around the foundation, can save a home from becoming a haven for moisture-loving insect pests.
Have you ever discovered that your home’s wall voids had become infested with insect pests? If so, did the infestation start as a result of a plumbing leak?


Nurturing Creativity and Innovation through FabKids: A Case Study
Ronald Noel Beyers
Journal of Science Education and Technology Volume 19, Number 5, ISSN 1059-0145
This paper will report on a case study that was conducted involving Grade 10 learners who were exposed to a high-tech rapid-prototyping environment of a Fabrication Laboratory as part of a FabKids experience. This project must be viewed in the context of a global shortage of key skills placing a higher priority on the initiation and development of a pipeline to attract youth into science, engineering and technology careers. Creativity and innovation feature high on the skills agenda but more importantly preliminary results indicate that learners from a broad range of schools were able to operate effectively in this post constructivist environment. Participants had to apply their knowledge, skill, attitudes and values in order to produce a solution to the challenges provided. The fundamentals of the design process of investigate, design, make, evaluate and communicate were emphasized where the FabKids had to draw on their own collective knowledge using a range of technologies available to them.

Magnetic Resonance Imaging (MRI)
Magnetic resonance imaging (MRI) uses radio waves and a strong magnetic field to provide images of internal organs and tissues. It does not use X-rays. Functional MRI is a procedure that uses MRI to indirectly measure the neural activity occurring in the brain of humans (or other animals). When neurons are active, they consume oxygen. The local response to this oxygen consumption is an increase in blood flow, localized to the regions of increased neural activity.
Functional magnetic resonance imaging (fMRI)
This hemodynamic response occurs after a delay of 1 – 5 seconds, lasts several seconds, and leads to local changes in the relative concentration of oxygenated and deoxygenated haemoglobin. As haemoglobin is diamagnetic when oxygenated but paramagnetic when deoxygenated, the MRI signal of blood is slightly different depending on its level of oxygenation. Using an appropriate sequence (often referred to as Blood Oxygenation Level Dependent or BOLD contrast), MRI is capable of measuring that slight difference in magnetic property. Unlike event-related brain potentials, functional MRI has a poor temporal resolution (in the order of seconds), but a high spatial resolution (in the order of millimetres). Therefore, both acquisition methods are complementary.

Ajanta: The end of the Golden Age
By Walter M. Spink
Published by BRILL - 2005 - History
The twenty-nine Buddhist caves near Ajanta form a devotional complex which ranks as one of the world's most startling achievements, created at the very apogee of India's Golden Age. "Ajanta: History and Development," appears as part of the series Handbook of Oriental Studies, present the reader with a systematic treatment of all aspects of the site, the result of forty years of painstaking research "in situ" by Walter M. Spink. Volume one deals with the historical context in which this dramatic burst of pious activity took place under the reign of Vakataka emperor Harisena, (c. 460 - 477 A.D.), and with the sudden halt of activity almost immediately following the death of the emperor. In surprising detail the relative and absolute chronology of the site can be established from a careful reading of the physical evidence, with consequences for our dating of India's Golden Age. Ajanta, it appears, is a veritable illustrated history of Harisena's times, crowded with information on its history, development and how it was used.

Iii The Specific Factors Model Consider A Two Sector Economy Consisting Of Manuf
III The specific-factors model
Consider a two-sector economy consisting of manufacturing (M) and services (S) with three types of workers: workers with special skills in manufacturing (LM), workers with special skills in services (LS), and unskilled workers (L), who can work equally in both sectors. Both, LM and LS are assumed to be fixed. No other factors of production are required in either industry. Call the tree kinds of wages wm, ws and w.
Draw the “open-box diagram” with L on the horizontal axis, as well as the demand curves for L in the M and S sectors. Also mark the areas under these curves with appropriate wage bills, where LM wm is the wage bill paid to specialized workers in M, Lm w is the wage bill paid to unskilled workers in M, LS ws is the wage bill paid to specialized workers in S and Ls w is the wage bill paid to unskilled workers in S.
Suppose that, due to the introduction of free trade, the price of M products rises. What are the consequences for production in the two sectors and what will happen to the wage rates of the three kinds of workers. Consider nominal and real changes.
Suppose now that due to technical change in manufacturing the productivity there increases. What will happen to the production of manufactures and services? And who will benefit and lose?
What kind of educational or technology policy would the different kinds of workers prefer? Consider training of workers in specific skill categories, as well as subsidies for technical change.

Damascus: Charcoal Burners
The charcoal burner (faḥḥām) principally worked with branches of holm oak, gathered from the lands around Damascus. These were burned in a pit covered with earth or a layer of turf. The charcoal was loaded into sacks and sold for domestic and industrial use in Damascus. It was a profitable activity. See also: Woodcutter (kissār or kassār) and Wood gatherer (ḥaṭṭāb).

Fuel for Thought
The beginnings of what we call “fossil fuels,” because the original ingredients are ancient organisms: Coal is the remains of plants that lived near swamps in humid regions millions of years ago.
Oil is the remains of ancient algae, plankton, and bacteria which got buried under rock.
The same ingredients and conditions that create oil also create natural gas, also known as methane or CH4. Oil and gas are often found together when drilling.
Ethanol, which you often see mentioned as part of the fuel blend at gas station pumps, is fermented from the starch and sugar found in common crops like corn, wheat, barley, potatoes, sugar cane, and sorghum. Notably, the Ford Model T ran on a gasoline / ethanol blend, but the grain fuel was temporarily banned in 1919 in the US as part of prohibition, since it was considered an alcoholic beverage.
The most common types of fuels for nuclear power plants are uranium-235 and plutonium-239. Natural uranium is mined, and after much refining and enriching, the metal is processed into fingertip-sized pellets which each contain the energy equivalent of a ton of coal or 149 gallons of oil. Plutonium, which fuels over a third of most power plants’ output, is actually a by-product of the initial uranium reaction.
Geothermal energy is clean and renewable, but this heat from underground the must be fairly hot to produce electricity. For this reason, areas near tectonic plate boundaries can produce more geothermal energy. El Salvador, Iceland, New Zealand, Kenya and the Philippines, all countries with major tectonic plate boundaries under or near them, are among the big geothermal power producers. Incidentally, the Earth’s heat itself is from leftover from our planet’s formation, still cooling off 4.5 billion years after it was first formed.
Those slick, huge, modern wind turbines are made of high-tech materials, but using windmills to harness windpower for food production goes back nearly 2000 years, and they were used for electrical generation as far back as 1888.


Science reports: Last month, geographer Richard Heede received a subpoena from Representative Lamar Smith (R-TX), chairman of the House of Representatives Committee on Science, Space, and Technology. Smith, a climate change doubter, became concerned when the attorneys general of several states launched investigations into whether ExxonMobil had committed fraud by sowing doubts about climate change even as its own scientists knew it was taking place. The congressman suspected a conspiracy between the attorneys general and environmental advocates, and he wanted to see all the communications among them. Predictably, his targets included advocacy organizations such as Greenpeace, 350.org, and the Union of Concerned Scientists. They also included Heede, who works on his own aboard a rented houseboat on San Francisco Bay in California.
Heede is less well known than his fellow recipients, but his work is no less threatening to the fossil fuel industry. Heede (pronounced “Heedie”) has compiled a massive database quantifying who has been responsible for taking carbon out of the ground and putting it into the atmosphere. Working alone, with uncertain funding, he spent years piecing together the annual production of every major fossil fuel company since the Industrial Revolution and converting it to carbon emissions.
Heede’s research shows that nearly two-thirds of anthropogenic carbon emissions originated in just 90 companies and government-run industries. Among them, the top eight companies — ranked according to annual and cumulative emissions below — account for 20 percent of world carbon emissions from fossil fuels and cement production since the Industrial Revolution.

It is true that a lot on-line content material is unreliable. However, participants’ issues typically seem exaggerated.
to encourage more people to participate in on-line discussions, given the possibility for increased opinion sophistication for individuals who take part. Some analysis suggests that people participate to be sociable, to turn out to be more informed on political subjects, to hear diverse views including those from the “other side,” to learn more about their own opinions, to vent their anger at current occasions or insurance policies (Stromer-Galley, 2003), and to pass the time and have enjoyable (Svensson, 2015).
To a big extent they proceed from dutiful concepts of what politics is and how it must be engaged in, and social media don’t match this picture. According to the participants, political exercise above all means working in political events and civic organizations, participating in protest marches and handing out leaflets (Sveningsson, 2013), i.e., traditional political actions that happen within the physical offline world. As talked about above, it’s probably that the specific characteristics of the sample are reflected within the results. One potential interpretation is that it might even be the individuals’ relative data that works in opposition to their turning into engaged in politics on social media. Although they specific a insecurity of their data, the interviews and discussions clearly show that they are up-to-date on what happens in their society and in the world.

The Freedom of Matzah
Matzah is a paradox. On the one hand, it symbolizes freedom... Yet, matzah is the simplest product – just flour and water. How can that express freedom?
Matzah is a paradox. On the one hand, matzah symbolizes freedom. We recline while eating it, unlike the bitter herbs which symbolize slavery. Yet, matzah is the simplest product – just flour and water. How can that express freedom?
To understand what freedom is, let us describe the opposite of freedom, which is dependence. A person who cannot survive the day without a cigarette is not a fully free man. He is restricted by the need for cigarettes.
In order to attain our full measure of freedom, we first simplify our base “needs.” Therefore, the matzah symbolizes freedom as it is the simplest of all, consisting of nothing more than flour and water. The less our needs, the greater our freedom to do that which is right.
My father, Samuel Werbin, of blessed memory, recently passed away. He exemplified the meaning of freedom by not being dependent on materialism as his primary source of happiness. He was known as a man of integrity and principle, and he loved giving to others, which he did generously.
One of the last times we went out together, my dad, feeling very weak, asked me to drive him home. Earlier, I had mentioned that I wanted to buy a new watch. Just before arriving at his house, he requested that I continue driving past the house, which was odd since he wasn’t feeling well. After arriving at the shopping center that he directed me to, I realized that my dad had led me to a watch store. Despite his suffering, my dad used his limited energy and strength to give to another.
As we eat the matzah on seder night, let us reflect that we are ‘resetting’ our base level of needs. In so doing, we become truly free, with the ability to act upon principles and do that which is right – the way Dad lived his life.

Early in the pandemic, scientists tried training dogs to infections in humans. The results were predictable. Man’s best friend proved adept at sniffing out the disease, but the question researchers kept asking themselves was how they would scale that approach. After all, training a dog is expensive, and taking care of one can be a handful.
Still, the idea of using animals to spot sick humans is a good one and one that a team of researchers from Michigan State University approached in a novel way. In a recent study published in the journal , they detailed a locust-based cancer screening system. Per , the tech involves surgically-altered locusts with electrodes implanted into the lobes of their brains by Professor Debajit Saha and his colleagues. Those electrodes were there to capture signals from each insect’s antennae, which they use to sense smells.
Additionally, the team grew three different types of cancerous human mouth cells – in addition to a separate set of healthy ones – and built a device for capturing the gases emitted by those tissues. They then used that device to give the insects a whiff of the gases. They found that the locusts' brains responded to each type of tissue differently and that they could correctly identify sick cells with only the recording of the gasses.
It’s hard to say if you’ll ever see your local clinic uses insects for cancer screenings. The study hasn’t been peer-reviewed yet, and it’s difficult to know if regulators like the Food and Drug Administration would ever approve such a procedure. People could also find the treatment of the locusts questionable. “The insect is dead in terms of its body function,” Saha told MIT Technology Review. “We are just keeping its brain alive.”
Saha and his team plan to continue work on the project. Their current system requires between six and 10 locust brains to function. He hopes new electrodes will allow his team to record more neurons, thereby making a single locust brain sufficient for an individual screening. He also wants to make the device holding the brain and antennae portable, which would allow the team to use the system outside of a lab.


The signal molecule, retinoic acid, is a product of vitamin A which helps to instruct how different types of tissue are to be formed in the growing embryo. For the first time, researchers from the Lund University have studied the effects of retinoic acid in relation to how blood cells develop from human stem cells. In the laboratory model, the stem cells are exposed to specific signal molecules, thereby developing into blood-producing cells.
The researchers observed that increased levels of retinoic acid drastically reduced the number of blood cells that could be produced. A reduction in the retinoic acid instead increased the production of blood cells by 300 per cent. On the basis of these results, the team propose a new explanatory model of how retinoic acid affects the embryonic development of blood. The opensource study is published in the journal Stem Cell Reports.
Even if vitamin A is required for a normal pregnancy, the researchers stress that it has long been known that too much vitamin A can be damaging to the foetus, with the risk of foetal malformation and miscarriage. Pregnant women have therefore been recommended to limit their consumption of foods that are high in vitamin A in the form of retinoids, such as liver.
The results show that vitamin A in high doses has a negative effect on blood development. This suggests that there is an additional reason for pregnant women to avoid excessive intake of vitamin A during pregnancy. While the concept that retinoic acid affects blood cell development has been demonstrated in animal models, this is the first time the experiments have been done using human cells.
The team state that the current study is about finding ways of artificially generating blood stem cells for use in blood stem cell transplants to patients with blood disorders and cancers, who do not have access to a suitable donor. They summise that the findings increase the medical community’s understanding of the complexity of the process of blood formation during embryonic development. The team hope that this, together with new future discoveries, will lead to the generation of blood stem cells in the laboratory, which in turn can be used to treat blood disorders and malignancies.

To tackle the growing amount of microplastics in the world’s seas, Grimaldi has developed and patented a system that filters out microplastics from open loop scrubber wash-water. Wärtsilä, in partnership with the Neapolitan group, will take the microplastics filtration system, which traps plastic particles before the wash-water is returned to the ocean, to market. The capability to filter microplastics will be an integrated feature of Wärtsilä’s future wash-water treatment system.
The new system uses the natural capabilities of an open loop scrubber to contribute to cleaning the oceans during each voyage. Currently, a 10-megawatt engine will require scrubbers to process approximately 450 m3 of water per hour, potentially resulting in a large amount of microplastics being captured from seawater. According to early test results, the microplastics filtration system is efficient in capturing particles smaller than 10µm and the captured concentration by volume equals around 76 particles/m3.
Adding an abatement solution for microplastics to Wärtsilä’s portfolio further strengthens its commitment to use exhaust gas cleaning systems as a part of a modular platform that can enable further environmental technology innovations.


Sand dunes are constantly shifting and changing mounds of sand formed over many years by windblown sand particles that have become trapped by beach grass. The roots of these dune grasses help to anchor the sand dunes in place. Think of sand dunes as natural fencing with an abundance of benefits! Sand dunes are a wonderfully protective feature of our treasured Florida coastline, providing an amazing array of nature’s necessities…
The first thing one might notice about sand dunes is that they are part of what creates the magnificent natural character of Florida’s coastal environment.
Sand dunes also act as shielding sentinels defending against the winds and weather, tides and its swells; providing coastal protection to the land beyond them and a buffer against erosion caused by those waves and storms.
Similarly to everyone who loves the Florida coastline with abandon, a bunch of little critters happen to be abundantly grateful for sand dunes as well. The sand dunes here create an incredible, self-sustaining ecosystem and provide a natural and protective habitat to a wide variety of species including shore birds, small mammals, toads, lizards, snakes, crabs, mollusks and insects. The sand dunes in New Smyrna Beach also provide a comfy nesting ground for our beloved sea turtles!
Plus, here’s a fun fact…Sometimes the sand dunes take on a life of their own by making a singing noise that is caused by small avalanches along the length of the dunes.

Título: Pink-backed pelican
Especie: Nesting birds
The pink-backed pelican is the smallest of the eight pelican species. This bird can grow up to 125-155 centimeters, weight around 4 to 7 kilograms and wingspan of 2,15 to 2,9 meters. Pink-backed pelicans may live between 15 – 25 years in the wild and up to 54 years under human care.
Breeding can take place year-round and unlike many pelican species, pink-backed pelicans nest on trees. Nests are built using sticks, close one to another and one and the same nest can be reused year after year if it's in a good condition or can be repaired. After courtship, one to three eggs are laid. Both parents will help to raise the young, who will fledge between 70 – 85 days.
Designated as Least Concern, threats for them include draining wetlands, tree loss and pollution."
