Hygrometer. Dry / Wet-bulb temperature. v. t. e. Psychrometrics (or psychrometry, from Greek ψυχρόν (psuchron) 'cold' and μέτρον (metron) 'means of measurement'; [ 1][ 2] also called hygrometry) is the field of engineering concerned with the physical and thermodynamic properties of gas - vapor mixtures .
The stimulus–response model is a conceptual framework in psychology that describes how individuals respond to external stimuli. According to this model, an external stimulus triggers a reaction in an organism, often without the need for conscious thought. This model emphasizes the mechanistic aspects of behavior, suggesting that behavior can ...
Euthyroid sick syndrome ( ESS) is a state of adaptation or dysregulation of thyrotropic feedback control [ 1] wherein the levels of T3 and/or T4 are abnormal, but the thyroid gland does not appear to be dysfunctional. This condition may result from allostatic responses of hypothalamus-pituitary-thyroid feedback control, dyshomeostatic disorders ...
Sleep cycle. The sleep cycle is an oscillation between the slow-wave and REM (paradoxical) phases of sleep. It is sometimes called the ultradian sleep cycle, sleep–dream cycle, or REM-NREM cycle, to distinguish it from the circadian alternation between sleep and wakefulness. In humans, this cycle takes 70 to 110 minutes (90 ± 20 minutes). [ 1]
Figure 1: A Carnot cycle illustrated on a PV diagram to illustrate the work done. Figure 2: A Carnot cycle acting as a heat engine, illustrated on a temperature-entropy diagram. The cycle takes place between a hot reservoir at temperature T H and a cold reservoir at temperature T C. The vertical axis is temperature, the horizontal axis is entropy.
In the ego psychology model of the psyche, the id is the set of uncoordinated instinctual desires; the superego plays the critical and moralizing role; and the ego is the organized, realistic agent that mediates between the instinctual desires of the id and the critical superego; [1] Freud compared the ego (in its relation to the id) to a man ...
6061 sheet in the T4 condition can be formed with limited ductility in the cold state. For deep draw and complex shapes, and for the avoidance of spring-back, an aluminium hot stamping process ( Hot Form Quench ) can be used, which forms a blank at a elevated temperature (~ 550 C) in a cooled die, leaving a part in W-temper condition before ...
The Roman physician Galen mapped the four temperaments (sanguine, phlegmatic, choleric and melancholic) to a matrix of hot/cold and dry/wet, taken from the four classical elements. [1] Two of these temperaments, sanguine and choleric, shared a common trait: quickness of response (corresponding to "heat"), while the melancholic and phlegmatic ...
