PULHES is a United States military acronym used in the Military Physical Profile Serial System. It is used to qualify an enlistee's physical profile for each military skill . Each letter in the acronym (see box below) is paired with a number from 1 to 4 to designate the service member's physical capacity.
PULHHEEMS is an abbreviation for the factors it is intended to test. These include: Physique Upper limbs Lower limbs (or 'Locomotion', as this includes the back) Hearing (right) Hearing (left) Eyesight right (corrected / uncorrected) Eyesight left (corrected / uncorrected) Mental function Stability (emotional)
The medical section of the SRP includes a series of medical examinations and evaluations consistent with the PULHES Factor rating scheme, which is used to qualify an soldier's physical profile for each military skill. PULHES stands for physical capacity, upper body, lower body, hearing, eyes, and psychiatric. [9]
Physical profile (The PULHES Factor) = 111121 or better; Correctable vision of 20/20 in one eye and 20/100 in other eye; Normal color vision; A minimum score, of 87 in aptitude area CO (ASVAB/GT score) Formal training (completion of military occupational specialty I 19D course conducted under the auspices of the U.S. Army Armor School) mandatory
The limiting factors here are each of different character and usually cannot be dealt with the same way and/or (and very likely) they cannot be all addressed. The term attractiveness principle was first used by inventor of system dynamics Jay W. Forrester. [1] According to Forrester, the only way to control growth is to control attractiveness. [1]
The identification of a factor as limiting is possible only in distinction to one or more other factors that are non-limiting. Disciplines differ in their use of the term as to whether they allow the simultaneous existence of more than one limiting factor (which may then be called "co-limiting"), but they all require the existence of at least one non-limiting factor when the terms are used.
A low level of one factor can sometimes be partially compensated for by appropriate levels of other factors. In case of chemical reactions it is known as law of limiting factor. A corollary to this is that two factors may work synergistically (e.g. 1 + 1 = 5), to make a habitat favorable or unfavorable. Geographic distribution of sugar maple.
Liebig's law states that growth only occurs at the rate permitted by the most limiting factor. [ 2 ] For instance, in the equation below, the growth of population O {\displaystyle O} is a function of the minimum of three Michaelis-Menten terms representing limitation by factors I {\displaystyle I} , N {\displaystyle N} and P {\displaystyle P} .
