Fatigue deterioration

For statie design to be valid in praetiee, we must assume situations where there is no deterioration of the material strength within the time period being eonsidered for the loading history of the produet. With a large number of eyelie loads the material will eventually fatigue. With an assumed statie analysis, stress rupture is the meehanism of failure to be eonsidered, not fatigue. The number of stress eyeles in a problem eould... 

Adverse reactions may include ataxia, vertigo, fatigue, hyperirritability, emotional disturbances, diplopia, nystagmus, drowsiness, personality deterioration with mood changes, paranoia, nausea, anorexia, vomiting, megaloblastic anemia, thrombocytopenia, impotence, morbilliform or maculopapular skin eruptions, crystalluria. 

Regenerator cyclones have a typical life of 15-30 years depending upon erosion and mechanical fatigue. The base metal of the cyclones will deteriorate with time leading to graphitization. Once this happens, the metal cannot be welded upon and hence cannot be repaired during a normal unit TAR. This phenomenon is dependent upon time and temperature. COP is used to minimize the temperature to extend the cyclone life. 

Gene expression inhibition. Chloroform/ methanol extract (1 1) of the dried leaf, in cell culture, was active on hepatoma-Cos-7, IC50 600.0 pg/mL vs TAT-dependent activation of HIV promoter hioassay - . Hepatotoxic activity. The leaf, taken orally by a female adult, was active - . A patient consumed 15 tablets of the leaf per day for 4 months. Approximately 1 year after stopping consumption, liver enzymes returned to normal and fatigue was no longer a complaint - ". Infusion of the dried leaf, taken orally by a female adult at variable doses, was active. The 60-year-old woman who took Lama tridentata for 10 months developed severe hepatitis for which no other cause could be found. Despite aggressive supportive therapy, the patient s condition deteriorated and required orthotropic liver transplantation - " . Dried leaves, administered orally to adults at variable doses, were active. A public warning has been issued by the US Centers for Disease Control based on reports of liver toxicity after use of Lama tridentata tea - " k Dried leaves, administered orally to adults of both sexes at variable doses, were active - ". The plant, administered orally to adults at variable doses, was active - ". Dried leaves, administered orally to adults at variable doses, were active. One case of hepatotoxicity induced by Larrea tridentata taken as a nutritional supplement was reported - ". Thirteen patients were identified for whom Larrea tridentata tincture for internal use was prescribed. Additionally, 20 female and three male patients were identified from whom an extract of Larrea tridentata in castor oil for... 

Fatigue, dynamic The deterioration of a material by a repeated deformation. 

Cocaine, amphetamine, dextroamphetamine, methylphenidate, and pemoline are classified as psychomotor stimulants, producing an acute euphoria in control subjects, as well as a wide variety of responses in psychiatric patients. These stimulants are also effective in postponing the deterioration in psychomotor performance that often accompanies extreme fatigue, a property that may be useful in some carefully selected cases. 

ASTM D430, 1995 (2000). Rubber deterioration - Dynamic fatigue. 

The increased mental drive necessary to maintain performance was apparent in another study of military recruits kept awake for 3 successive nights (18). An increase in fatigue was accompanied by a decline in rifle-shooting accuracy, both reflecting circadian rhythmicity over which the deteriorating trend was superimposed. There was a clear rhythm in circulating noradrenaline whose peak increased on each of the 3 days of sleep deprivation.
