Chronic fatigue syndrome
Chronic fatigue syndrome (CFS), also referred to as myalgic encephalomyelitis (ME), is a medical condition characterized by long-term fatigue and other symptoms that limit a person's ability to carry out ordinary daily activities. Biological, genetic, infectious, and psychological mechanisms have been proposed, but the cause is not understood. Diagnosis is based on a person's symptoms. The fatigue is not due to strenuous ongoing exertion, is not much relieved by rest, and is not due to a previous medical condition. Fatigue is a common symptom in many illnesses, but the unexplained fatigue and severity of functional impairment in CFS is comparatively rare.
History of chronic fatigue syndrome
The history of chronic fatigue syndrome (CFS, also known by many other names) is thought to date back to the 19th century and before. Several descriptions of illness resembling those of chronic fatigue syndrome have been reported for at least two hundred years. In the 19th century, neurologist George Miller Beard popularised the concept of neurasthenia, with symptoms including fatigue, anxiety, headache, impotence, neuralgia and depression. This concept remained popular well into the 20th century, eventually coming to be seen as a behavioural rather than physical condition, with a diagnosis that excluded postviral syndromes.
Clinical descriptions of chronic fatigue syndrome
The clinical descriptions of chronic fatigue syndrome (CFS) vary. Different agencies and scientific bodies have produced different guidelines to define the condition, with some overlap of symptoms between descriptions. Aspects of the condition are controversial, with disagreements over etiology, pathophysiology, treatment and naming between medical practitioners, researchers, patients and advocacy groups. Subgroup analysis suggests that, depending on the applied definition, the CFS population may represent a variety of conditions rather than a single disease entity. The most widely used diagnostic criteria for CFS are the 1994 research guidelines proposed by the "International Chronic Fatigue Syndrome Study Group", led by the Centers for Disease Control and Prevention.
Chronic fatigue syndrome treatment
Treatment of chronic fatigue syndrome (CFS) is variable and uncertain, and the condition is primarily managed rather than cured. Only two treatments, cognitive behavioral therapy and graded exercise therapy, have demonstrated reproducible evidence for their efficacy people with CFS who are walking. There are no Food and Drug Administration (FDA) approved medications for ME/CFS treatment, although medications are used without approval for the illness (off-label). Drugs have been used in experimental studies of the illness that haven't been approved for market for any condition in the United States (for example, isoprinosine and rintatolimod).
Fibromyalgia
Fibromyalgia (FM) is a medical condition characterised by chronic widespread pain and a heightened pain response to pressure. Other symptoms include tiredness to a degree that normal activities are affected, sleep problems, and troubles with memory. Some people also report restless legs syndrome, bowel or bladder problems, numbness and tingling, and sensitivity to noise, lights or temperature. Fibromyalgia is frequently associated with depression, anxiety, and posttraumatic stress disorder. Other types of chronic pain are also frequently present. The cause of fibromyalgia is unknown; however, it is believed to involve a combination of genetic and environmental factors with half the risk attributed to each.
Irritable bowel syndrome
Irritable bowel syndrome (IBS) is a group of symptoms—including abdominal pain and changes in the pattern of bowel movements without any evidence of underlying damage. These symptoms occur over a long time, often years. It has been classified into four main types depending on whether diarrhea is common, constipation is common, both are common, or neither occurs very often (IBS-D, IBS-C, IBS-M, or IBS-U respectively). IBS negatively affects quality of life and may result in missed school or work. Disorders such as anxiety, major depression, and chronic fatigue syndrome are common among people with IBS.
Lyme disease
Lyme disease, also known as Lyme borreliosis, is an infectious disease caused by bacteria of the "Borrelia" type which is spread by ticks. The most common sign of infection is an expanding area of redness on the skin, known as erythema migrans, that begins at the site of a tick bite about a week after it has occurred. The rash is typically neither itchy nor painful. Approximately 25–50% of infected people do not develop a rash. Other early symptoms may include fever, headache and feeling tired. If untreated, symptoms may include loss of the ability to move one or both sides of the face, joint pains, severe headaches with neck stiffness, or heart palpitations, among others.

History of science and technology in the People's Republic of China
For more than a century China's leaders have called for rapid development of science and technology, and science policy has played a greater role in national politics in China than in many other countries. China's scientific and technical achievements have been impressive in many fields. Although it has been a relatively low-income, developing country, China has by its own efforts managed to develop nuclear weapons, the ability to launch and recover satellites, supercomputers, and high-yield hybrid rice, among others. But the development of science and technology has been uneven, and significant achievements in some fields are matched by low levels in others.
Ceramic capacitor
A ceramic capacitor is a fixed-value capacitor in which ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore applications. Ceramic capacitors are divided into two application classes:  Ceramic capacitors, especially multilayer ceramic capacitors (MLCCs), are the most produced and used capacitors in electronic equipment that incorporate approximately one trillion (10) pieces per year. Ceramic capacitors of special shapes and styles are used as capacitors for RFI/EMI suppression, as feed-through capacitors and in larger dimensions as power capacitors for transmitters.
Environmental governance
Environmental governance is a concept in political ecology and environmental policy that advocates sustainability (sustainable development) as the supreme consideration for managing all human activities—political, social and economic. Governance includes government, business and civil society, and emphasizes whole system management. To capture this diverse range of elements, environmental governance often employs alternative systems of governance, for example watershed-based management. It views natural resources and the environment as global public goods, belonging to the category of goods that are not diminished when they are shared.
Intergovernmental Panel on Climate Change
The Intergovernmental Panel on Climate Change (IPCC) is a scientific and intergovernmental body under the auspices of the United Nations, set up at the request of member governments, dedicated to the task of providing the world with an objective, scientific view of climate change and its political and economic impacts. It was first established in 1988 by two United Nations organizations, the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), and later endorsed by the United Nations General Assembly through Resolution 43/53. Membership of the IPCC is open to all members of the WMO and UNEP.
Scientific opinion on climate change
The scientific opinion on climate change is the overall judgment among scientists regarding the extent to which global warming is occurring, its likely causes, and its probable consequences. The scientific consensus is that the Earth's climate system is unequivocally warming, and that it is "extremely likely" (meaning 95% probability or higher) that this warming is predominantly caused by humans. In 2013, 12,000 peer reviewed papers on climate science were analyzed. This analysis showed that 97% of scientists believe that climate change is happening and is human-caused. It is likely that this mainly arises from increased concentrations of greenhouse gases in the atmosphere, primarily from the burning of fossil fuels, partially offset by human-caused and volcanic aerosols; natural change has had little effect.
Search and rescue
Search and rescue (SAR) is the search for and provision of aid to people who are in distress or imminent danger. The general field of search and rescue includes many specialty sub-fields, typically determined by the type of terrain the search is conducted over. These include mountain rescue; ground search and rescue, including the use of search and rescue dogs; urban search and rescue in cities; combat search and rescue on the battlefield and air-sea rescue over water. International Search and Rescue Advisory Group (INSARAG) is a UN organization that promotes the exchange of information between national urban search and rescue organizations.
