Input: Task: corroborate the claim using the given text. Claim: Biodegradable plastics are part of ongoing research to reduce plastic pollution and environmental impact. [SEP] Text: Numbers of initiatives are being adopted at national and global level to redesign, reduce, reuse or recycle waste plastics by adopting circular economy model. It is the need of the hour that firms invest in R&D labs, seek biodegradable alternatives as replacement for synthetic plastic polymers including innovative packaging material, products and processes to mitigate the harmful effects of plastics. Countries need to impose regulations to import oxy-biodegradable single-use plastics only and enforce complete ban on usage of non-biodegradable plastics. Collaborated efforts are required by countries around the world to discourage single use plastics, adopt compostable and biodegradable plastic products and recycle the existing mismanaged waste to provide a cleaner and sustainable environment for the coming generations. 1.

Output: The text corroborates the claim by discussing the need for firms to invest in research and development (R&D) for biodegradable alternatives to synthetic plastics. It emphasizes that adopting biodegradable products is part of initiatives aimed at addressing plastic pollution and environmental issues. The mention of countries needing to impose regulations on non-biodegradable plastics reinforces the idea that biodegradable options are seen as a key part of the solution to mitigate the harmful effects of plastic.


Input: Task: contrast the claim using the given text. Claim: Microbial fuel cells are guaranteed to work in all environmental conditions. [SEP] Text: This thesis investigates characteristics and performance of EcAB in the anodic compartment of pure- and mixed-culture MFCs in an effort to shed light to processes important to MFC performance and efficiency. In order to reliably study EcAB in a microbial fuel cell environment, a gas-tight, sterile MFC setup was developed and optimized for electrochemical and microbiological studies of the anodic bacteria and consequently the electrochemically active biofilm/bioanode. In addition, a method for Geobacter species quantification with quantitative PCR (qPCR) was developed. Furthermore, a multiple-unit MFC setup was designed for convenient and simultaneous operation of identical MFCs ‘in-parallel’. A design for a new compact, multi-array MFC to be used as a small-scale culturing platform of EcAB based solely on their electrochemical properties is also introduced. Our research with different titanium (Ti) electrodes in the same MFC setup, suggests that the MFC electrode surface is critical as it determines attachment of EcAB and bioanode formation that leads ultimately to efficient electrochemical activity. Pt- and Ta- coated Ti electrodes performed the best while uncoated Ti with either smooth or rough surfaces performed the worst. Future MFC research could benefit greatly from enhancing the electrode interface for optimum bioanode formation and electron transfer. Our studies with flat-plate, graphite-electrode, mixed-culture microbial fuel cells (Pmax ≈ 1 W/m2) operated for several months with external load (Rext), indicated stable and reproducible characteristics including Coulombic efficiencies, average values of cell voltage, anode potentials, and current densities as well as main microbial populations of both the anolyte and the bioanode. However, transient testing of power maxima values (Pmax) that required lower Rext, or applied potential showed result variability, that might be linked to differences in electrochemical impedance factors, redox-active centers and electron-producing states of the bioanodes. Differences in the quantities of the bioanode microbial species did not seem to correlate with this variability. Since energy-conserving applications like waste-water treatment MFCs would ideally be operated with an Rext rather than applied voltage, addressing interface impedance factors, such as charge transfer resistance and electrical double layer capacitance, is important especially when MFCs are operated at lower Rext. [SEP] Justify:

Output: The text contrasts the claim by discussing the conditions under which microbial fuel cells (MFCs) can perform effectively. It highlights variability in results from transient testing and points out factors like electrochemical impedance and charge transfer resistance that impact efficiency. This suggests that MFC performance is not guaranteed across all environmental conditions, as indicated by statements like 'result variability' linked to 'differences in electrochemical impedance factors'.


Input: Task: pass the claim using the given text. Claim: Some mushrooms can bioaccumulate heavy metals from the soil. [SEP] Text: 8° corresponding to (112), (211), and (422) for Pb (II). The XRD spectrum is compared with the exited spectrums of control that have been published by the on Standards (JCPDS file no. 00-002- 097) and (JCPDS file no. 00-002-085) respectively. The average crystal size of the un-loaded control, loaded with Cd (II) 50 mgl-1, and Pb (II) 50 mgl-1 nanop20. 0, 27. 8, and 14. 0 respectively. The results of XRD patterns of D. radiodurans show three sharp peaks with a decrease in the intensity of the these peaks for un-loaded biosorbent after exposing the bacteria to Pb (II) and Cd (II), which could explain the immobilization process. This is in agreement with the results reported in the literatures of [23-25]. And this may suggest that Pb (II) and Cd (II) immobilized on surface of D. radiodurans [26]. Transmission electron microscope One of the most important of TEM techniques has revealed the internal structure of the bacteria, especially when embedding bacteria in a resin and staining thin sections of the resulting block with uranyl acetate. Figure 3a shows the cells of D. radiodurans before interaction with metals while Figure 3b,3c show the bacteria after exposure to Pb and Cd solutions. Metals were mostly seen on the cell wall, looking almost like a crust around the cell in addition to the change in the size and the shape of cells. The cellular localization of the metals bound by the cells of study bacteria was located mainly within the cell wall. However, some intracellular metal accumulates associated were also identified in the cytoplasm of the bacterial cells [27]. Reported that, the cellular localization of the uranium bound by the cells was located mainly within the cell wall of three types of A. ferrooxidans using TEM.

Output: The text does not address the claim regarding mushrooms and bioaccumulation of heavy metals. It primarily discusses the interactions of certain bacteria with heavy metals, particularly Pb and Cd, and the methods used to observe these interactions. Thus, the text is considered irrelevant to the claim.


Input: Task: pass the claim using the given text. Claim: All biodegradable plastics are safe for marine life and will not harm ocean ecosystems. [SEP] Text: Added text: “Ideally, the rate of biological change should be calculated using a non-linear model following the shape of the non-linear performance curve between pH and the tested parameter (e. g. Fig. 3b for % of abnormality). These performance curves can take many forms depending on the measured parameter and species. For example, common shapes of physiological performance curves include U-shape, sigmoidal, logarithmic, exponential, and inverted U-shape (Little & Seebacher, 2021). However, in practice the shape of these curves is often unknown and it would not be possible to derive relevant rates of change from biological observations over relatively short period of time. Under these circumstances, using a linear regression is good alternative. “ Reviewer comment: The model seems to be based on a single example, abnormality of Mytilus edulis. It is questionable that there is a linear relationship between chemical and biological change in all species and in all indicators. I suggest to use the large amount of laboratory results (OA-ICC at the database pangaea. de) and a variety of indicators to develop a more robust model. Author response: The reviewer is quite correct, and the example projections made in this manuscript are based on a non-linear dose response (from Ventura et al. 2016). We then illustrate what the output would be using linear regression (and the associated errors). While we agree that using this approach with other species or even higher taxonomic groups (using synthesis and meta-analysis) is an extremely valuable thing to do we would see this as the natural next step, following on from this current manuscript. As such we consider this new body of work to be beyond the scope of this current manuscript that focusses primarily on presenting a methodology that can be applied by others to do exactly the kind of activity proposed by the reviewer. Reviewer comment: The conclusion that insensitive systems require longer monitoring is trivial from the viewpoint of an experimental biologist as this must be considered when planning experiments and when interpreting results. While clearly illustrated in this manuscript, I doubt that this is new information to researchers involved in monitoring programs. Author response: The reviewer makes a fair point about researchers already involved in biological monitoring, we would respectfully argue that this paper is not solely being directed towards that existing community. [SEP] Justify:

Output: The text provided is irrelevant to the claim regarding biodegradable plastics and their safety for marine life. It discusses non-linear models of biological change and their applicability, particularly in the context of Mytilus edulis, but does not mention biodegradable plastics or their impact on ocean ecosystems. Therefore, it does not corroborate or contrast the claim.


Input: Task: contrast the claim using the given text. Claim: Microbial fuel cells are guaranteed to work in all environmental conditions. [SEP] Text: Furthermore, mixed-culture MFCs were shown to be selective for certain bacterial consortia, including Geobacter- and Pseudomonas- related species. Geobacter-related species were dominant on the surface of different electrodes suggesting a pivotal role of the species in electrochemical activity and EET. This was not surprising as the original mixed-culture inoculum - used for starting up several bioelectrochemical systems at our research facilities - was amended with pure cultures of G. sulfurreducens PCA. However, the strain specifically selected for and present in most bioanodes was a novel Geobacter, strain T33 that was phylogenetically closely related (99% by 16S rRNA sequence similarity) to several strains detected in a variety of MFCs operated by other research groups under various conditions and anodic substrates. These strains formed a new phylogenetic Geobacter cluster, distinct from G. sulfurreducens. This observation suggested that strain T33 might have an ecological advantage in MFCs over G. sulfurreducens PCA. In-depth characterization of strain T33 in pure-culture experiments showed that strain T33 forms efficient bioanodes with high Pmax similar to strain PCA, but exhibits different redox-centers than strain T33. Furthermore, strain T33 has a more limited electron acceptor range, but a wider electron donor range than strain PCA, including glucose and succinate. Phylogenetic analysis indicated that strain T33 and recently described electrochemically active strains G. soli GSS01 and G. anodireducens SD-1 are closely related (99% by 16S rRNA) and form a new phylogenetic cluster within the Geobacters, 98% by 16S rRNA similar to G. sulfurreducens strains PCA and KN400. Genome-based analyses indicates that even though the two clusters share common metabolic properties, some differences exist with respect to electron donor utilization, attachment and conductive cell surface components (e-pili) production and genome rearrangement and gene acquisition. It is not sufficiently clear how the differences in the genome of strain T33 are relevant to persistence of the strain in MFCs, biofilm formation and EET, our studies overall suggest that strain T33 even though producing similar power densities as G. [SEP] Justify:

Output: The text contrasts the claim by highlighting that different strains of bacteria, such as strain T33 and G. sulfurreducens PCA, exhibit varied metabolic properties and adaptability under diverse environmental conditions. The mention of different electron donor and acceptor ranges for strain T33 implies that microbial fuel cells (MFCs) may not be universally effective in all scenarios, as the performance can depend on the specific bacterial strains used and their compatibility with the operational conditions.

DOI: 10. 15406/aaoaj. 2021. 05. 00132 : As man aims to go beyond the reach of the solar system, technologies that are capable of achieving such distances pose serious problems. One being that spacecrafts are not fast enough to reach destinations and hence it takes extremely a long time. The solution to this would be near light speed or faster light speed travel. It is debated highly that such travel is not possible due to conventional physics, but when man breaks the norms and looks outside the box solutions can be found. The closest star is a few light years away and with conventional engines it can take decades and centuries to reach. The use of antigravity and antimatter engines have also been researched widely at many institutions like NASA and other agencies which make major leaps in this field however very rarely have significant solutions been found, this is why the following paper is going to be discussing how NLS and FTL light speed can be achieved. The type of propulsion source proposed would be wrap drives along with field propulsion in order for the spacecraft to bend space to get to destinations faster. This solution might reduce the time it take to reach stars by a huge amounts. To put things into better perspective spacecrafts might be able to reach in a few years (3-5 years) with this technology.

Output: The text discusses travel at near light speed and faster than light speed (FTL), highlighting that such speeds address the problem of long travel times to distant stars. It indicates that traveling at 'near light speed or faster light speed' is necessary to reduce travel time significantly, supporting the claim that noticeable time dilation effects would require speeds close to that of light.

Input: Task: pass the claim using the given text. Claim: For time dilation to be significantly noticeable, travel would need to approach speeds near the speed of light. [SEP] Text: This is because the angle of attack or the wave strength is directly related to the size of wave being propagated and the smaller the spacecraft the lighter it is and hence the speed of the wrap does not need to be as high as that of a heavy spacecraft and hence calculating the degree at which the microwave and the magnetic waves are propagated is very important for the acceleration and the speed. The main power source is close to 100% efficient and hence the power requirements of the spacecraft can also be met. Furthermore the formula E = mc2 states that energy is equal to mass times the speed of light squared. When the formula of E=MC2 is substituted c = square root of ( energy x mass). This is why the amount of energy and mass required to achieve light speed differs. The higher it is however the better unless the spacecraft is able to substitute for it by adjusting the other parameters such as the field size and the magnitude and the weight. The total exact amount of energy that 1g of matter and 0. 5 g matter can produce is equivalent to 21. 5 kilotons of energy. Assuming 3g of anti matter and 6 g of matter is used the amount of energy produced would get an extremely vast number which is why it is so efficient. The formulae used to wrap and bend space time would be (Figure 2). Figure 2. 1 Einsteins field equation. Figure 2. 2 Einsteins space time equation. Figure 2. 3 Wrap drive and NLS/FTL speed equation. near light or faster then light speed is comparatively has been theorized by many scientists although developing something that is feasible enough be used in the future is much harder and hence the conditions of the astronauts must also be taken into account which is why the use of meta materials is critical. The instantaneous acceleration causes extreme G forces which is why the main cockpit would need to be made in way so that the pilots don’t face such forces. Some of this technology can be taken from hyper loops and can be further advanced. The spacecraft would also need to be capable of operating under any and most circumstances which is why the spacecraft would need to be capable of operating under the stresses of space.

Output: The text does not address the claim directly as it focuses on various aspects of spacecraft design, energy production, and the challenges of achieving high speeds in space travel. It discusses energy efficiency, spacecraft weight, and the impact of acceleration on astronauts, but does not provide specific details or arguments that either corroborate or contrast the claim regarding time dilation being noticeable at speeds near light.

Soil fungal networks are more sensitive to grazing exclusion than bacterial networks. PeerJ 8:e9986 microbial communities play a crucial role in ecological restoration, but it is unknown how co-occurrence networks within these communities respond to grazing exclusion. This lack of information was addressed by investigating the effects of eight years of grazing exclusion on microbial networks in an area of Stipa glareosa P. Smirn desert steppe in northern China. Here, we show that fungal networks were more sensitive to grazing exclusion than bacterial networks. Eight years of grazing exclusion decreased the soil fungal community stability via changes in plant composition and reductions in soil total organic carbon, in this case triggering negative effects on the S. glareosa desert steppe. The results provide new insights into the response mechanisms of soil microbes to grazing exclusion and offer possible solutions for management issues in the restoration of degraded desert steppe. has a long history and remains the common land use type in grasslands (Bai et al. , 2004). However, overgrazing has led to serious deterioration of grassland ecosystems in China during the past three decades (Hoffmann et al. , 2008; Li et al. , 2008). In response to regional environmental problems, the Chinese government launched some grassland restoration programs, such as the “lands to Grasslands” in 2003 and the “Protection Program” in 2011, to mitigate grassland degradation by prohibiting grazing and increasing grassland vegetation biomass (Hao et al. , 2014; Bryan et al. , 2018). In these projects, various degraded grasslands were fenced for different numbers of years and grazing was permanently prohibited. Therefore, grazing exclusion has been widely used in for curbing grassland degradation and restoring damaged ecosystems (Bai et al. , 2004; Hao et al. , 2014). However, the effects of grazing exclusion are controversial depends on its vegetation types, environmental conditions, and duration (Jing et al. [SEP] Justify:

Output: The text does not address the claim about the abundance of fungal spores as airborne particles. Instead, it discusses the sensitivity of soil fungal networks to grazing exclusion and explores ecological restoration efforts. Therefore, the text is irrelevant to the claim.


Input: Task: corroborate the claim using the given text. Claim: For time dilation to be significantly noticeable, travel would need to approach speeds near the speed of light. [SEP] Text: The main propulsion source has been proven on various occasions as well and hence using this might be a good idea, anti matter has been experimented at places such as CERN and new research is showing that anti matter can be synthesized on Earth as well, this is why when closely looked at old and new data being produced it can be seen that achieving light speed and faster then light speed might be possible, furthermore it is possible to achieve light speeds using a wrap drive due to the fact that it can bend space time which is a very important part in the acceleration of the spacecraft. Many people argue that this is not completely feasible however new advances in meta materials have been done to prove that it is possible. Institutions like UC Berkeley have found out new materials that have a extremely high tenacity to stress in space. This shows us that it is possible to undertake the stresses of space using the new technologies being created. This being said a lot of advancement can be done in this field but currently theoretically and even physically lots of things mentioned in this paper are possible. Further research into synthetic wormholes might allow humanity to reach destinations at a even a faster rate but in the coming decades and years a lot can be done to further advance this field. Furthermore the various formulae used may also spark discussions on the validity and the usefulness of the sources. The main scientists whose equations the paper contain are Einsteins field equation, Einstein space time equation, the E=MC2 formula, data from the Higgs boson condensate, the formulas used in the wrap drive, the Einstein unified field theory. Each of values mentioned in the paper have been put in and have been verified which is why the main sources and the numbers used are verified. Theoretically majority of the systems should be able to work but implementation is quite hard which is why it is estimated the that a functional wrap drive and a functional spacecraft capable of light speed might be able to be created within the next decade, although this is true this is just a estimate and it might take more or less time to complete this scale of a project. Many scientists further believe that it might not be possible to travel at light distances because of the various problems associated with the speed of light, the acceleration, temperatures and the power as well as the time dilation and the sociological impact of it on the astronauts. [SEP] Justify:

Output: The text corroborates the claim by discussing how significant advancements in propulsion and space travel, particularly those involving warp drives and the bending of spacetime, are tied to achieving light speed or faster-than-light travel. It implies that for significant time dilation to occur, travel needs to be at speeds close to that of light, as it acknowledges the challenges and potential issues associated with reaching such speeds, including time dilation itself. Furthermore, the mention of the sociological impact on astronauts hints at the changes that high-speed travel could invoke, reinforcing the notion that one would need to approach light speed for noticeable time dilation effects.

Input: Task: pass the claim using the given text. Claim: Fungal spores are among the most abundant airborne particles. [SEP] Text: , 2014; Yan & Lu, 2015; Yao et al. , 2019). Grazing exclusion can not only change ecosystem processes to promote the survival of local plants, but can also affect the activity and structure of soil microbial communities by increasing nutrient availability (Bastida et al. , 2013; Zhang et al. , 2018). The soil microbial community is a key driver of grassland ecosystems and of crucial importance for soil functioning (Bardgett, Wardle & Yeates, 1998). A major challenge is to understand how these complex communities respond to grazing exclusion. Many studies have demonstrated that grazing exclusion can have considerable effects on soil microbial communities, often with consequences for plant community dynamics (Cheng et al. , 2016; Bi et al. , 2018). It has also been shown that bacteria recover faster than fungi and with the rates being differentially governed by plant diversity (Zhang et al. , 2018). Although these past studies provide important insights into grazing exclusion and microbial communities, up to now few data have been available concerning the impacts of grazing exclusion on soil microbial interactions. Soil microbes can form a complex inter-species network that regulates the structure of ecological communities (Zhou et al. , 2011; Lupatini et al. , 2014). Evidence is mounting that the properties of these interaction networks can influence the response of soil microbial communities to environmental change (et al. , 2018; Marcos, Bertiller & Olivera, 2019). In recent years, microbial network analysis has been used as a tool to explore the interactions in a range of environments, providing important details on microbial cooperation and competition (Faust & Raes, 2012; Yu et al. , 2018). Additionally, microbial networks have been highlighted as crucial to understanding the dynamics of microbial community assembly and the responses of member interactions to a changed environment (Zhou et al. , 2011). A previous study performed in arid region of Patagonia observed an increase in positive network connections, indicating that there are more cooperative relationships within the microbial community to survive under the stressful conditions imposed by grazing (Marcos, Bertiller & Olivera, 2019). In addition, a study performed in drylands of northern china showed that microbial interaction in extremely dry ecosystems is more sensitive to changes in water availability (Wang et al. , 2018). Although the use of network analysis has increased in drylands, little has been revealed on how soil microbial interactions respond to grazing exclusion, especially in desert grassland ecosystems.

[SEP] Text: While many areas such as the wrap drive, gravitational bending devices, field propulsion and even solutions to instantaneous acceleration have been researched upon a lot of things can be done to completely make light speed efficient. Many types of engines such as the helical engine developed by NASA have also proven to be successful although achieving 99% the speed of light may still pose challenges in reaching the destinations desired. Many future advancements are also happening at this moment and there might be more papers on how to achieve light speed but achieving 100% light speed and even more might still pose a challenge if principals used in physics is consistently applied. conclude the theory of light speed is possible and with valid discussions from scientists it is possible to do so currently although the main problem currently faced is actually implementing the solutions. With the current advancement in technology it is likely that by a decade or so light speed might be physically possible and might allow humans to reach the stars and the galaxy systems in less time. Furthermore the main technologies used and mentioned in this paper might be controversial although as time and advances in the field of physics it is very likely the phenomenas and the main technologies can be actually be proven and even tested in the future. The conclusion to the solution is that it is feasible and even viable and as humans aim to go beyond the reach of the solar system such technologies would be very important for long distance travel. In total this system is completely reliable and is comparatively easier to develop under the right situation and time making this very efficient. A lot of the technologies used in the paper are mainly new such as the new type of anti matter system, anti graviton electromagnetic field propulsion system and the zero point energy generator as well as the entire wave generation system, this makes the spacecraft and the technologies more modern which is a good thing because this relies on some principals of scientists like Einstein and newton and Maxwell but also uses new types of technology to and combines a bit of theory developed by the scientists to give us the solution of light speed aircraft, this is why the entire solution provided in the paper is completely proofed using the formulas but also using some basic principals of physics and then majorly advancing it to give us the solutions presented.

[SEP] Text: The desert steppe of cover about 20% of China’s desertification land area, which is characterized by harsh physical environments, infertile soil, and simple plant community composition (Wang et al. , 2020). These natural ecosystems support the life of about 95% of the human population (Li et al. , 2008). However, drought and dust storms have become the largest meteorological disasters in this area causing sparse vegetation and land desertification, which are exacerbated by overgrazing (Wang et al. , 2020). In this study, we designed to assess the effects of eight-years of grazing exclusion on soil bacterial and fungal networks. We also aimed to test the changes in plant and soil properties and investigated how these changes affected the response of bacterial and fungal networks to grazing exclusion. Materials and site The study site was located in Erlianhot (43°38′34. 44″−43°38′54. 29″N, 112°07′58″E, 952–955 m elevation) of Inner Mongolia, northern China. The area has an arid and semiarid climate and is highly prone to drought, receives little precipitation, and frequently has strong winds. The annual mean temperature is 3. 4 °C, annual mean precipitation is 142. 2 mm, and approximately 70% of the annual rainfall occurs from July to August. The main soil types in this area are Aeolian sandy soils, with low fertility and loose structure. The representative vegetation includes S. glareosa, Cleistogenes songorica (Roshev. ) Ohwi, and Asparagus cochinchinensis (Lour. ) Merr communities, but the vegetation has been greatly altered by long-term overgrazing. Experimental design and sampling The experiment was conducted in late August 2017, when grassland biomass was at its peak. We selected one site with two treatments: grazing excluded (GE) and grazed (G). Inside the grazing excluded area (comprising an area of 200 m × 200 m paddock), livestock has been excluded from this region since 2009 and the remaining site in the area was subjected to free grazing by sheep continuously all the year. Within the grazed and grazing exclude area, we established three 50 × 50 m (50 m apart) plots, respectively (Fig. S1). [SEP] Justify:

Output: The text discusses environmental conditions, soil compositions, and experimental design related to grazing exclusion in a specific region of China, focusing on bacterial and fungal networks without addressing the claim about fungal spores being abundant airborne particles. Therefore, it is irrelevant to the claim.

Food & science: How to grill a flavorful steak That peculiar piece of meat — likely to be the first of its kind ever sold in the US — comes from a radical sort of food technology now in development, in which meat is produced by culturing muscle cells in vast tanks of nutrients. A similar effort — to culture mammary cells — is also underway and may soon yield real milk without cows. The company behind Crenn’s chicken, California-based Upside Foods, got a thumbs-up in November 2022 from the US Food and Drug Administration, which said it had no concerns about the safety of the technology. (The company’s manufacturing facility still requires a certificate of inspection from the US Department of Agriculture. )This cellular agriculture, as some of its proponents call it, faces formidable technical obstacles before it can ever be more than a curiosity. But if it does reach the mainstream, it offers the prospect of a cruelty-free source of meat and dairy — potentially with a smaller environmental footprint than conventional animal products. Conceptually, cellular agriculture is straightforward. [SEP] Justify:

[SEP] Text: At each of the three plots, three 1 m × 1 m quadrats were randomly selected to investigate vegetation height, species number, and aboveground biomass. The number of species was used to estimate the richness of the plant communities, and the diversity of the vegetation was calculated using the Shannon–Wiener index (H′ = − ∑Pi lnPi, where Pi is the ratio of the number of each species to the total number of all species). Plant aboveground biomass was harvested by clipping standing plant species to 1 cm above the ground. Plant material was then oven-dried at 65 °C for 48 h. To assess the effect of grazing exclusion on plant community structure, all plant species were classified into six functional groups: annuals and biennials (AB), perennial rhizome grasses (RG), tall perennial bunchgrasses (TG), short perennial bunchgrasses (SG), shrubs and semishrubs (SS), and forbs (FB). Soil samples were collected from the top 20 cm of the soil profile using an auger after the vegetation was sampled. Nine soil cores were collected from each plot (three core points for each quadrat) and then mixed into a single soil sample. A total of six soil samples were collected from two study areas and sieved immediately and air-dried for physicochemical analyses. Next, ten plants of S. glareosa per plot were excavated carefully with adhering rhizosphere and bulk soil. The soil that could be shaken off easily from the roots was defined as bulk soil, and the soil that remained firmly adhered to the root was defined as the rhizosphere. At each of the three plots, the rhizosphere and the bulk soil samples of the ten plants were mixed into a single soil sample separately. The soils were sealed in 15 ml sterile plastic tubes, immediately frozen on dry ice, and stored at −80 °C until DNA extraction. Soil physicochemical analyses The soil samples were sieved through a 2-mm mesh to remove roots and then ground and homogenized with a mill (MM400, Retsch, Germany). 15 g of fresh soil was weighed before and after dried at 105 °C for 24 h to calculate the soil water content (SWC).

Output: The text is irrelevant to the claim regarding fungal spores being abundant airborne particles. It primarily discusses methods of sampling and analyzing plant communities and soil, without mentioning fungal spores or air quality.


Input: Task: corroborate the claim using the given text. Claim: Lab-grown meat is created by cultivating animal cells in a controlled environment, mimicking traditional meat production. [SEP] Text: Technicians take a small tissue sample from a chicken, cow or other animal. From that, they isolate individual cells that go into a bioreactor — basically a big vat of nutrient solution — where the cells multiply manyfold and, eventually, mature into muscle, fat or connective tissue that can be harvested for people to eat. Products in which these cells are jumbled together, as in ground meat, are easiest to make, and that’s what most cellular meat companies are developing, at least initially. has a more ambitious goal: to create chicken with whole muscle fibers. “We’ve figured out ways to produce that textural experience,” says Eric Schulze, Upside’s vice president of product and regulation. He declines to explain exactly how they do it. Cellular meat is cultivated in tanks at Upside Foods, a company now developing products for commercial use. Cultivation facilities such as this use large amounts of electricity, so their environmental impact depends greatly on whether they draw electricity from sustainable sources. : process takes two to three weeks from start to finish, regardless of whether they are making chicken or beef. That’s much faster than the eight to 10 weeks required to raise a fryer chicken, or the 18 to 36 months needed for a cow. “We’re doing a cow’s worth of meat in 21 days or less,” says Schulze. One cellular meat product is already available commercially, though not in the US. In Singapore, a few restaurants and street vendors now offer a chicken nugget that contains a mix of cellular meat and plant-based ingredients. The product sells for about the same price as organic, farm-raised chicken, but the true cost of production is higher. “We’re selling it at a loss, for sure,” says Vítor Espírito Santo, senior director of cellular agriculture at Good Meat, the US-based company producing the nugget. But the cost should come down once the company expands to larger scale, Santo says. “Everything we do right now is more expensive because we are using a 1,200-liter bioreactor. Once we are producing in 250,000 liters, it will be competitive with conventional meat. ” The company is now working on gaining approval in the US. [SEP] Justify:

Output: The text corroborates the claim by providing a detailed explanation of the process of lab-grown meat production. It describes how a small tissue sample is taken from an animal, which is then used to isolate individual cells that are cultivated in a bioreactor. This directly aligns with the claim that lab-grown meat is produced by cultivating animal cells in a controlled environment. The mention of techniques to create different types of meat, the time efficiency compared to traditional meat production, and the cultivation at facilities like Upside Foods further supports the assertion made in the claim.

[SEP] Text: The soils were subjected to Kjeldahl digestion, and the soil total nitrogen (TN) concentration was determined using a semi-autoanalyzer (Kjeltec 2300 Analyzer Unit, Foss Tecator, Sweden). Soil total phosphorus (TP) concentration was measured by persulfate oxidation followed by colorimetric analysis (Schade et al. , 2003). Soil total organic carbon (TOC) was determined with a TOC-5000A analyzer (Shimadzu Corp. , Kyoto, Japan). Soil pH was measured using a ratio of soil:water = 1g:2. 5 ml with a Delta pH-meter (Mettler-). DNA extraction and high-throughput sequencing Three replicate rhizosphere and bulk soil samples were used for DNA extraction. DNA was extracted from 0. 5 g of soil with a FastDNA® SPIN Kit for soil () according to the manufacturer’s instructions. The final DNA concentrations and their purity levels were determined using a NanoDrop® ND-1000 (Nanodrop, USA), with DNA quality checked by 1% agarose gel electrophoresis. The DNA was then stored at −80 °C until use. The V3–V4 hypervariable region of the bacterial 16S rRNA gene was amplified using the specific primers 341F (5′--3′) and 806R (5′--3′) (Mori et al. , 2014), and the fungal internal transcribed spacer 1 (ITS1)-ITS2 region was amplified using the primers ITS1F (5′--3′) and ITS2R (5′--3′) (Bokulich & Mills, 2013; Hugerth et al. , 2014).

The company that made them, Good Meat, is working toward gaining approval for these and other products in the as well. : isn’t the only animal product that can come from cell cultures. Several companies are working to produce milk by culturing mammary cells and collecting the milk they secrete. For example, Opalia, a Montreal-based company, grows mammary cells on the surface of a three-dimensional, branched structure that resembles the lobules of a real udder, says CEO Jennifer Côté. The cells secrete milk into the structure’s lobules, where it can be collected and drawn off. Some other companies, such as North Carolina-based BioMilq, are using a similar technology with human mammary cells to produce human breast milk. None are yet on the market. In some ways, the process for making milk is easier than producing meat because the cells themselves don’t need to be harvested and replaced. “The cells we use can stay alive for multiple months on end,” says Côté. That means the company can concentrate on developing cells that secrete a lot of milk, rather than ones that divide rapidly. Moreover, she adds, because the cells themselves are not part of the product, Opalia can genetically modify its cells without the milk itself being a GMO product. Proponents hope that cellular meat and milk can eventually offer several big advantages over the conventional versions. By cutting animals out of the process, cultured products do away with most of the animal-welfare issues that beset modern factory farms. Meat and milk that come from clean culture facilities instead of manure-laden farmyards should also be less likely to carry food-borne diseases, says Elliot Swartz, lead scientist for cultivated meat technology at the Institute, a Washington DC-based nonprofit organization supporting alternatives to meat. Cellular milk is made by harvesting udder cells from a cow, then growing those cells in a large tank, or bioreactor. Eventually, the cells are encouraged to secrete milk that can be drawn off for use. This overview shows the production process being developed by Canada-based Opalia. [SEP] Justify:

Input: Task: corroborate the claim using the given text. Claim: Lab-grown meat is created by cultivating animal cells in a controlled environment, mimicking traditional meat production. [SEP] Text: To bring the cost down under $6 per pound, only a little pricier than conventional ground beef, would require a much larger, 260,000-liter bioreactor. The first meat from cultured cells was produced in 2013 by (pictured) and his colleagues at the University of Maastricht in the Netherlands. The patty shown here (raw on left, cooked on right) cost an estimated 250,000 euros (about $330,000 at 2013 exchange rates). Costs have come down since then, but cellular meat is still more expensive than conventional meat. : cultured meat may not have to match the price of ground beef or chicken to be commercially viable. Some consumers will probably pay higher prices to avoid the ethical and environmental costs of conventional meat, just as they do today for plant-based meat substitutes like Impossible and Beyond Meat. And some conventional products such as caviar, foie gras or bluefin tuna are so expensive that cultured versions could probably be cost-competitive pretty soon, says Swartz. That would give manufacturers a way to bring in some profits even as they work to bring costs down further. Another intermediate step could be to use cultured meats to enhance the flavor of plant-based products, as is doing now with the part-cultured-meat, part-plant-based meat patties they sell in Singapore. Manufacturers could also add cultured animal fat cells to give a meatier flavor to a plant-based product. “You only need maybe 5 percent animal fat to achieve that,” says Swartz. Such hybrid products, he thinks, are likely to be the dominant role for cellular meat in the next decade. Similar first steps could help cultured-milk companies generate revenue before they can match cow’s milk in price. Breast milk offers enough advantages over infant formula, says Swartz, that many consumers are likely to pay high prices for cultured human milk from BioMilq and other companies. “There are a variety of proteins and fatty acids and sugars that are simply not there if you don’t have breast milk,” says Nurit Argov-Argaman, a lactation physiologist at the of Jerusalem. Argov-Argaman is also chief scientist at Wilk, an Israeli company that is culturing human breast cells to extract high-value components such as fatty acids and lactoferrin, a protein essential to iron uptake, to enrich infant formula.

Input: Task: contrast the claim using the given text. Claim: Microbial fuel cells are guaranteed to work in all environmental conditions. [SEP] Text: Additionally, dual chamber MFCs were operated to investigate the recovery of heavy metals. In this work the integration of the MFC technology in the recovery of heavy metals from end of life (EoL) photovoltaic panels (PVP) was examined. Following a proposed EoL PVP recycling process, which included mechanical, thermal and chemical processing of the PVPs, a chemical extract containing the heavy metals of the PVP solar cell thin film was generated. Initially synthetic cathode solutions containing silver and indium were tested. Afterwards, the chemical extract originating from 2nd generation EoL PVP was used in the MFC cathode, to study the metal recovery. Silver recovery was high in the cases studied (>93%), with silver depositions on the cathode electrode and sediments in the cathode chamber. Additionally, the maximum power density obtained was 0. 8 W/m3 corresponding to a silver reaction rate of 2. 65 g Ag/h/m2. Indium recovery up to 96% was achieved during the synthetic indium wastewater experiments, with a maximum power density of 0. 17 W/m3. On the other hand, during indium recovery from the EoL 2nd generation PVP chemical extract, a higher power output was recorded (3. 5 W/m3), with indium depositions (oxides) on the cathode electrode, corresponding to 87% recovery. To further examine the MFC performance a 2D model simulating the operation of a dual chamber MFC was developed. The MFC technology was investigated experimentally and computationally in order to optimize the performance of this beneficial and environmentally friendly way to treat wastewater. περισσότερα Διαβάστε τη διατριβή (Online) Κατεβάστε τη διατριβή σε μορφή PDF (6.

The changes in each variable induced by grazing exclusion were indicated as the natural log-transformed response ratio, lnR = ln( X ¯ E ) −ln( X ¯ C ), where X ¯ E and X ¯ C are the mean values of the variables that were observed in experimental group and control group, respectively (Hedges, Gurevitch & Curtis, 1999). The variance of lnR was calculated using the following equation: ν = SD E 2 n E X ¯ E 2 + SD C 2 n C X ¯ C 2 where SDE and SDC are the standard deviation for the experimental group and control group, respectively; nE and nC are the sample size (number of replicates) for the experimental group and control group, respectively. Principal component analysis (PCA) at OTU level was used to visualize patterns in bacterial and fungal community structures. Differences in bacterial or fungal community composition between grazed and grazing-excluded grasslands were tested using analysis of similarity () tests with Bray–Curtis in the ‘vegan’ package, in R software (v2. 15. 3).

Output: The text is irrelevant to the claim as it discusses statistical analysis methods and network construction without mentioning airborne particles or fungal spores. Therefore, it does not provide any support or contradiction to the claim regarding the abundance of fungal spores in the air.


Input: Task: corroborate the claim using the given text. Claim: Artificial meat requires fewer resources, like land and water, compared to traditional livestock farming. [SEP] Text: IntroductionThe agricultural sector uses the largest share of freshwater resources worldwide. The average worldwide freshwater consumption per person was about 1385 m3, of which agriculture, industry and domestic use consumed about 91, 5, and 4%, respectively (Ouda 2014). In the Middle East, agriculture accounts for over 75% of total water consumption. However, with increasing demand resulting from population growth coupled with higher living standards, water will be reallocated away from the agriculture sector to the domestic and industrial sectors (Karrou et al. 2011; Ouda 2014). A rational water resource management plan (WRMP) requires the estimate of direct and indirect consumptions of water. The concept of water footprint (WFP) has been increasingly used as an indicator of water consumption and it is an informative tool for comprehensive understanding of water demand at national level (Hoekstra 2003; Chapagain and Hoekstra 2003; Charchousi et al. 2015). Past studies reported that the major fractions of WFP were due to the agricultural and industrial consumptions, while agriculture consumed more than 80% of global freshwater supplies (Shiklomanov 2000; Mekonnen and Hoekstra 2011). Almost 30% of the global agricultural WFP was related to livestock animal production (Mekonnen and Hoekstra 2012). The WFP of many animal products is larger than the WFP of crop products with equivalent calorie value (Mekonnen and Hoekstra 2012). The average WFP per calorie for beef was 20 times larger than for cereals and starchy roots, while the WFP per gram of beef protein was 6 times larger than for pulses (Mekonnen and Hoekstra 2012). Earlier study reported that by replacing all meat with an equivalent amount of crop products, a 30% reduction of the food-related WFP per American citizen could be obtained (Mekonnen and Hoekstra 2012). However, there are several animal products, which have lower WFP than crop products when nutritional value is considered. The worldwide meat production has been projected to be double by 2050 in the developing countries, due mainly to the increase in production and consumption (2008; Steinfeld et al. 2006; Alexandratos and Bruinsma 2012; Ran et al. 2016), which is likely to intensify the freshwater crisis in the future (Rost et al. 2008; Ran et al. 2016). [SEP] Justify:

Output: The text supports the claim by discussing how the water footprint (WFP) of livestock production is significantly larger than that of crop products. It states that almost 30% of global agricultural WFP is related to livestock production and highlights that the WFP per calorie for beef is 20 times larger than for cereals. Additionally, it notes that replacing all meat with crop products could lead to a substantial reduction in food-related water usage. This information corroborates the assertion that artificial meat, which can be derived from crop products, would require fewer resources such as water compared to traditional livestock production.

[SEP] Text: Cell for the Treatment of microbial fuel cell is a potential alternative for the treatment of wastewater. In this process of water treatment, a substantial amount of energy is produced. Microorganisms are explicitly used in microbial fuel cells to generate electrons and protons that are involved in electrochemical reactions for the treatment of wastewater for the generation of power. Moreover, the efficiency of the treatment process and also the generation of power largely depend on the nature of the substrates used as feed, types of the microorganism used and the configurations of the cells. In view of an effective treatment process, various types of wastewater originated from a number of different sources have extensively been treated in microbial fuel cells using electrogenic microorganisms. Environment-friendly features of microbial fuel cells result in a better technology compared to the existing ones for the purpose.

Input: Task: pass the claim using the given text. Claim: Fungal spores are among the most abundant airborne particles. [SEP] Text: Pearson correlation was used to analyze the effect of grazing exclusion on the relationship between the plant characteristics, soil properties, and soil microbial diversity. Random networks with the same number of nodes and links were constructed to compare with the original network to determine general network characteristics (Zhou et al. , 2011). For each identified network, 100 randomly rewired networks were generated, and all network indexes were calculated individually (Maslov & Sneppen, 2002). The Z-test was used to test index differences between the molecular ecological networks and random networks, and the Student t-test was used to test for differences in network indexes under different conditions using standard deviations derived from the corresponding random networks. The relationships between molecular ecological networks and environmental factors (plant characteristics and soil properties) were analyzed with Module-EigenGene analyses (Zhou et al. , 2011; Deng et al. , 2012). Spearman correlations coefficients were calculated to depict the relationship between the abundance of microbes and environmental factors. Results with a P < 0. 05 were considered statistically significant.

Food & science: How to grill a flavorful steak That peculiar piece of meat — likely to be the first of its kind ever sold in the US — comes from a radical sort of food technology now in development, in which meat is produced by culturing muscle cells in vast tanks of nutrients. A similar effort — to culture mammary cells — is also underway and may soon yield real milk without cows. The company behind Crenn’s chicken, California-based Upside Foods, got a thumbs-up in November 2022 from the US Food and Drug Administration, which said it had no concerns about the safety of the technology. (The company’s manufacturing facility still requires a certificate of inspection from the US Department of Agriculture. )This cellular agriculture, as some of its proponents call it, faces formidable technical obstacles before it can ever be more than a curiosity. But if it does reach the mainstream, it offers the prospect of a cruelty-free source of meat and dairy — potentially with a smaller environmental footprint than conventional animal products. Conceptually, cellular agriculture is straightforward. [SEP] Justify:

Output: The text corroborates the claim by mentioning that cellular agriculture, which refers to the lab-grown meat production, 'faces formidable technical obstacles before it can ever be more than a curiosity.' This indicates that while progress is being made, there are indeed significant challenges that must be overcome for lab-grown meat to scale up to meet commercial demand.

Input: Task: corroborate the claim using the given text. Claim: Lab-grown meat production still faces challenges in scaling to meet commercial demands. [SEP] Text: Technicians take a small tissue sample from a chicken, cow or other animal. From that, they isolate individual cells that go into a bioreactor — basically a big vat of nutrient solution — where the cells multiply manyfold and, eventually, mature into muscle, fat or connective tissue that can be harvested for people to eat. Products in which these cells are jumbled together, as in ground meat, are easiest to make, and that’s what most cellular meat companies are developing, at least initially. has a more ambitious goal: to create chicken with whole muscle fibers. “We’ve figured out ways to produce that textural experience,” says Eric Schulze, Upside’s vice president of product and regulation. He declines to explain exactly how they do it. Cellular meat is cultivated in tanks at Upside Foods, a company now developing products for commercial use. Cultivation facilities such as this use large amounts of electricity, so their environmental impact depends greatly on whether they draw electricity from sustainable sources. : process takes two to three weeks from start to finish, regardless of whether they are making chicken or beef. That’s much faster than the eight to 10 weeks required to raise a fryer chicken, or the 18 to 36 months needed for a cow. “We’re doing a cow’s worth of meat in 21 days or less,” says Schulze. One cellular meat product is already available commercially, though not in the US. In Singapore, a few restaurants and street vendors now offer a chicken nugget that contains a mix of cellular meat and plant-based ingredients. The product sells for about the same price as organic, farm-raised chicken, but the true cost of production is higher. “We’re selling it at a loss, for sure,” says Vítor Espírito Santo, senior director of cellular agriculture at Good Meat, the US-based company producing the nugget. But the cost should come down once the company expands to larger scale, Santo says. “Everything we do right now is more expensive because we are using a 1,200-liter bioreactor. Once we are producing in 250,000 liters, it will be competitive with conventional meat. ” The company is now working on gaining approval in the US. [SEP] Justify:

Output: The text corroborates the claim by highlighting the current challenges in scaling lab-grown meat production, particularly through the mention of the high costs of production associated with small bioreactors and the fact that they are currently selling products at a loss. It also indicates expectations for costs to decrease only when production scales up to larger bioreactors, which underscores the difficulties in meeting commercial demand.

Input: Task: corroborate the claim using the given text. Claim: Lab-grown meat production still faces challenges in scaling to meet commercial demands. [SEP] Text: Enthusiasts also claim that cell-based products should be more sustainable than conventional animal products, because farmers will no longer need to feed, water and house entire animals just to harvest their muscles. It’s hard to know whether this benefit will pan out in reality, since the technology is still under development. Only a few studies have tried to estimate the environmental impact of cell-based meat, and all have made huge assumptions about what future technologies will look like. One thing seems clear, however. Cell-based meat relies heavily on electricity for tasks like heating or cooling culture tanks and pumping cells from place to place. If that electricity comes from renewables, the overall carbon footprint of cell-based meat will be much less than if it comes from fossil fuels, says Swartz. Assuming a relatively green electric grid, though, one careful study of cell-based meat’s potential, by the Dutch consulting company CE Delft, suggests that its environmental footprint is likely to be roughly the same as that of conventional pork or poultry — among the greener conventional meats, by most reckonings — and far less than that of beef. So far, however, companies and academic researchers have only taken baby steps toward cellular agriculture. If the industry is ever to grow big enough to change the face of global agriculture, it would need to overcome several major hurdles, says David Block, a chemical engineer at the University of California, Davis, who works on the technology behind cultured meat. Dutch researchers calculated the greenhouse gas emissions from various protein sources. As a best-case scenario, they assumed that by 2030 conventional protein products would be produced in a way that minimizes their greenhouse gas footprint: no forests cleared to grow animal feed, animals grazed outdoors when possible and only sustainable energy sources used on farms and in production. For cellular meat products, the main factor affecting greenhouse gas emissions is the source of the electricity used in production facilities: The standard footprint assumes the current mix of energy sources; the minimum footprint assumes that all energy comes from renewable sources. One of the biggest challenges, most experts agree, is finding an inexpensive way to supply the nutrients and growth factors the growing cells need. Existing culture media are far too costly and often depend on calves’ blood for molecules such as fibroblast growth factor and insulin-like growth factor 1, which are essential for cell growth and maintenance.
