CjHiaNO, [Mc3NCH= CH2] OH. A liquid forming a crystalline trihydrate, It is present free and combined in brain and other animal and vegetable products and is formed as a product of putrefaction of lecithin. It can be prepared synthetically from choline and decomposes easily to trimethylamine. neutralization, heat of The amount of heat evolved when I g equivalent of an acid is neutralized by 1 g equivalent of a base. For strong acids and strong bases in dilute solution the only reaction which occurs is H -h OH ---> H2O and the heat of neutral-... [Pg.272]

A young scientist said, I have never seen a complex scientific area such as industrial ventilation, where so little scientific research and brain power has been applied. This is one of the major reasons activities in the industrial ventilation field at the global level were started. The young scientist was right. The challenges faced by designers and practitioners in the industrial ventilation field, compared to comfort ventilation, are much more complex. In industrial ventilation, it is essential to have an in-depth knowledge of modern computational fluid dynamics (CFD), three-dimensional heat flow, complex fluid flows, steady state and transient conditions, operator issues, contaminants inside and outside the facility, etc. [Pg.1]

The body temperature limits for health in terms of internal or core temperature are fairly limited. The limits are basically related to the function of nervous tissue. Body temperatures around 28 °C or less can result in cardiac fibrillation and arrest. Temperatures of 43 °C and greater can result in heat stroke, brain damage, and death. Often, too high a temperature causes irreversible shape changes to the protein molecules of nervous tissue. That is, cooling overheated tissue to normal temperatures may not restore its original function. [Pg.176]

Hyperbolic expansion The expansion of a fluid according to the law pV = Hypothalamus The temperature control center at the base of the brain, which regulates body temperature. Hypothermia The physiological state resulting when the deep core body temperature drops below 35 C. It results in vasoconstriction and shivering in an attempt to conserve body heat. [Pg.1449]

Peripheral nervous system Nerve tissues lying outside the brain and spinal cord, functions include the transmittal of sensory information such as touch, heat, cold, and pain, and the motor impulses for limb movement. [Pg.1466]

Human brain natriuretic peptide (BNP) is a small peptide of 32 amino acids used in the treatment of congestive heat failure. How many nitrogen bases are present in the DNA that codes for BNP ... [Pg.1121]

When the temperature takes an icy dive, my brain puts in a non-negotiable request for the toddy effect. I basically want to mull my body with heated spirits. [Pg.173]

Ascorbic acid is photosensitive and unstable in aqueous solution at room temperature. During storage of foods, vitamin C is inactivated by oxygen. This process is accelerated by heat and the presence of catalysts. Ascorbic acid concentration in human organs is highest in adrenal and pituitary glands, eye lens, liver, spleen, and brain. Potatoes, citrus fruits, blade currants, sea buckthorns, acerola, rose hips, and red paprika peppers are among the most valuable vitamin C sources [1,2]. [Pg.1293]

The PNS is further divided into the somatic nervous system and the autonomic nervous system. The somatic branch of the PNS is concerned witii sensation and voluntary movement. The sensory part of the somatic nervous system sends messages to the brain concerning die internal and external environment, such as sensations of heat, pain, cold, and pressure The voluntary part of die somatic nervous system is concerned witii die voluntary movement of skeletal muscles, such as walking, chewing food, or writing a letter. [Pg.199]

As early as in 1909, it was recognized that some chemical factor in the brain was responsible for recovery sleep. Cerebrospinal fluid (Legendre Pieron, 1911) or brain extract (Ishimori, 1909) from sleep-deprived dogs resulted in excess sleep when infused into the cerebral ventricles of recipient animals. The fact that the material was ineffective if heated or ultrafiltered pointed to a protein or peptide as sleep factor (Legendre Pieron, 1911). Later studies have... [Pg.337]

TRPV4 was identified a decade ago as an osmotransducer that is expressed in lung, heart, kidney, airway muscle cells, sensory neurons, brain, skin, gut, sympathetic nerves, inner ear, endothelium, and fat tissue [58-61]. TRPV4 is activated by heat (27-34°C), endogenous substances such as anandamide (59, AA) and the arachi-donic acid metabolite 5,6-epoxyeicosatrienoic acid (60, 5,6-EET), a plant dimeric diterpenoid bisandrographolide A (61, BAA), and the semisynthetic phorbol ester 4a-phorbol-12,13-didecanoate (62, 4a-PDD) [62],... [Pg.45]
