Biological Responses in Context
Published in Arthur T. Johnson, Biology for Engineers, 2019
According to Maslow, the items lower on the list must be satisfied before striving for the upper ones (Figure 6.22.10). Those who are deprived of food, for instance, show markedly disturbed behavior. As starvation increases, people become more preoccupied with food and food-related objects; their intellectual functioning is impaired; personality deteriorates. Rehabilitation after starvation reverses all these effects (Harbaugh, 1972). While it is not likely that a biological engineer would design a facility specifically to starve people or animals, safety and security needs must be satisfied before the more social aspects of love, esteem, and self-actualization can be expected to occur. Designs of learning facilities, for instance, must be made recognizing that other more basic needs must also be satisfied.
Observational Network and Drought Monitoring
Published in Saeid Eslamian, Faezeh Eslamian, Handbook of Drought and Water Scarcity, 2017
Droughts cause an enormous amount of social losses and deprivations, which arise from lack of income, conflicts among the water users, and migration of the population out of the drought-affected areas. People seek to cope with drought in several ways that affect their sense of well-being: they withdraw their children from schools, postpone daughters’ marriages, and sell their assets such as land or cattle. Inadequate food intake may lead to malnutrition and, in some extreme cases, cause starvation. Access and use of scarce water resources generate a situation of conflict, which could be socially very disruptive.
Microbial metabolism and growth under conditions of starvation modelled as the sliding mode of a differential inclusion
Published in Dynamical Systems, 2018
Starvation refers in general to a restricted environmental availability of one or more essential nutrients, or even the complete absence of one or several of them. However, in those cases where the cell has accumulated a substantial amount of reserves, it may be able to bridge periods of low or zero ambient nutrient concentration by mobilizing these results. How long the cell is able to do this depends on the duration of the ‘famine’ and also on the levels of reserves it has built up; the latter depends in turn on the regulatory laws.
