Heat Exhaustion
Heat exhaustion is a heat-related illness characterized by the body's inability to effectively cool itself, typically occurring in high ambient temperatures or during intense physical exertion. In heat exhaustion, core body temperature ranges from 37 °C to 40 °C (98.6 °F to 104 °F). Symptoms include profuse sweating, weakness, dizziness, headache, nausea, and lowered blood pressure, resulting from dehydration and serum electrolyte depletion. Heat-related illnesses lie on a spectrum of severity, where heat exhaustion is considered less severe than heat stroke but more severe than heat cramps and heat syncope. Climate change and increasing global temperatures have led to more frequent and intense heat waves, raising the incidence of heat exhaustion. Risk factors include hot and humid weather, prolonged heat exposure, intense physical exertion, limited access to water or cooling, and certain medications that can exacerbate fluid and serum electrolyte losses incl ...

Emotional Exhaustion
Emotional exhaustion is a symptom of burnout, a chronic state of physical and emotional depletion that results from excessive work or personal demands, or continuous stress. It describes a feeling of being emotionally overextended and exhausted by one's work. It is manifested by both physical fatigue and a sense of feeling psychologically and emotionally "drained". An emotional hangover refers to the symptoms associated with a prolonged state of emotional exhaustion, which might occur following a highly emotional event, traumatic event or a stressful conversation. or situation due to cognitive dissonance and emotional processing, that may last for hours or days. They can also arise following intense emotional experiences such as a move or a large financial purchase. Burnout There are various ways in which burnout can occur such as: impacting an individual's physical, emotional, and behavioral aspects. Emotional exhaustion research has been guided by Christina Maslach's and Su ...

Exhaustion Of Intellectual Property Rights
The exhaustion of intellectual property rights constitutes one of the limits of intellectual property (IP) rights. Once a given product has been sold under the authorization of the IP owner, the reselling, rental, lending and other third party commercial uses of IP-protected goods in domestic and international markets are governed by the principle. After a product covered by an IP right, such as by a patent right, has been sold by the IP right owner or by others with the consent of the owner, the IP right is said to be exhausted. It can no longer be exercised by the owner. This limitation is also referred to as the exhaustion doctrine or first sale doctrine. For example, if an inventor obtains a patent on a new kind of umbrella, the inventor (or anyone else to whom he sells his patent) can legally prohibit other companies from making and selling this kind of umbrella, but cannot prohibit customers who have bought this umbrella from the patent owner from reselling the umbrella to thir ...

Proof By Exhaustion
Proof by exhaustion, also known as proof by cases, proof by case analysis, complete induction or the brute force method, is a method of mathematical proof in which the statement to be proved is split into a finite number of cases or sets of equivalent cases, and where each type of case is checked to see if the proposition in question holds. This is a method of direct proof. A proof by exhaustion typically contains two stages: # A proof that the set of cases is exhaustive; i.e., that each instance of the statement to be proved matches the conditions of (at least) one of the cases. # A proof of each of the cases. The prevalence of digital computers has greatly increased the convenience of using the method of exhaustion (e.g., the first computer-assisted proof of four color theorem in 1976), though such approaches can also be challenged on the basis of mathematical elegance. Expert systems can be used to arrive at answers to many of the questions posed to them. In theory, the p ...

Exhaustion By Compact Sets
In mathematics, especially general topology and analysis, an exhaustion by compact sets of a topological space X is a nested sequence of compact subsets K_i of X (i.e. K_1\subseteq K_2\subseteq K_3\subseteq\cdots), such that each K_i is contained in the interior of K_, i.e. K_i\subset\text(K_), and X=\bigcup_^\infty K_i. A space admitting an exhaustion by compact sets is called exhaustible by compact sets. As an example, for the space X=\mathbb^n, the sequence of closed balls K_i = \ forms an exhaustion of the space by compact sets. There is a weaker condition that drops the requirement that K_i is in the interior of K_, meaning the space is σ-compact (i.e., a countable union of compact subsets.) Construction If there is an exhaustion by compact sets, the space is necessarily locally compact (if Hausdorff). The converse is also often true. For example, for a locally compact Hausdorff space X that is a countable union of compact subsets, we can construct an exhaustion as fo ...

Method Of Exhaustion
The method of exhaustion () is a method of finding the area of a shape by inscribing inside it a sequence of polygons (one at a time) whose areas converge to the area of the containing shape. If the sequence is correctly constructed, the difference in area between the ''n''th polygon and the containing shape will become arbitrarily small as ''n'' becomes large. As this difference becomes arbitrarily small, the possible values for the area of the shape are systematically "exhausted" by the lower bound areas successively established by the sequence members. The method of exhaustion typically required a form of proof by contradiction, known as ''reductio ad absurdum''. This amounts to finding an area of a region by first comparing it to the area of a second region, which can be "exhausted" so that its area becomes arbitrarily close to the true area. The proof involves assuming that the true area is greater than the second area, proving that assertion false, assuming it is less than ...

Fatigue
Fatigue is a state of tiredness (which is not sleepiness), exhaustion or loss of energy. It is a signs and symptoms, symptom of any of various diseases; it is not a disease in itself. Fatigue (in the medical sense) is sometimes associated with medical conditions including autoimmune disease, organ failure, chronic pain conditions, mood disorders, heart disease, infectious diseases, and post-infectious-disease states. However, fatigue is complex and in up to a third of primary care cases no medical or psychiatric diagnosis is found. Fatigue (in the general usage sense of normal tiredness) often follows prolonged physical or mental activity. Physical fatigue results from muscle fatigue brought about by intense physical activity. Mental fatigue results from prolonged periods of Cognition, cognitive activity which impairs cognitive ability, can manifest as sleepiness, lethargy, or directed attention fatigue, and can also impair physical performance. Definition Fatigue in a medica ...

Exhaustion Of Remedies
The doctrine of exhaustion of remedies prevents a litigant from seeking a remedy in a new court or jurisdiction until all claims or remedies have been exhausted (pursued as fully as possible) in the original one. The doctrine was originally created by case law based on the principles of comity. In the United States, exhaustion of remedies is applied extensively in administrative law. Many cases are handled first by independent agencies of the United States government which have primary responsibility for cases involving the statutes or regulations which the agency administers. A person's specific rights and duties depend on the federal statute involved, but here is an outline of how the doctrine works in practice. "Exhaustion of administrative remedies" requires a person to first go to the agency which administers the statute; this process usually involves filing a petition, then going to a hearing, and finally using the agency's internal appeal process. Once the agency's ow ...

Nervous Exhaustion
Neurasthenia ( and () 'weak') is a term that was first used as early as 1829 for a mechanical weakness of the nerves. It became a major diagnosis in North America during the late nineteenth and early twentieth centuries after neurologist George Miller Beard reintroduced the concept in 1869. As a psychopathological term, the first to publish on neurasthenia was Michigan alienist E. H. Van Deusen of the Kalamazoo asylum in 1869. Also in 1868, New York neurologist George Beard used the term in an article published in the Boston Medical and Surgical Journal to denote a condition with symptoms of fatigue, anxiety, headache, heart palpitations, high blood pressure, neuralgia, and depressed mood. Van Deusen associated the condition with farm wives made sick by isolation and a lack of engaging activity; Beard connected the condition to busy society women and overworked businessmen. Neurasthenia was a diagnosis in the World Health Organization's ICD-10, but deprecated, and thus ...

Exhaust Date
The North American Numbering Plan (NANP) is an integrated telephone numbering plan for twenty-five regions in twenty countries, primarily in North America and the Caribbean. This group is historically known as World Zone 1, World Numbering Zone 1 and has the telephone country code, country code ''1''. Some North American countries, most notably Telephone numbers in Mexico, Mexico, do not participate in the NANP. The concepts of the NANP were devised originally during the 1940s by the American Telephone and Telegraph Company (AT&T) for the Bell System and the independent telephone companies in North America in Operator Toll Dialing. The first task was to unify the diverse local telephone numbering plans that had been established during the preceding decades, with the goal to speed call completion times and decrease the costs for long-distance calling, by reducing manual labor by switchboard operators. Eventually, it prepared the continent for direct-dialing of long-distance calls ...
