For example, in order to obtain sustained supply for raw timber from the forest, the timbers supplied from sustainably managed and certified forest is being encouraged (Päivinen et al. 2012).
In 2012, the WHO and various humanitarian organizations called for greater support in ensuring a sustained supply of pain medications in response to the Syrian conflict (UN Department of Public Information 2016; WHO 2014).
Especially during fasting when glycogen store are depleted and gluconeogenesis becomes the most important process for sustaining the supply of glucose, the kidneys increase their net contribution to glucose release [31].
The physiological relevance of vitamin E and the severe pathological consequences of its deficiency, such as neurological disorders or lung diseases, together with its dietary origin impose a major challenge for sustaining an adequate supply of this vitamin to different tissues [31].
A harvesting strategy of clearcutting for sustained timber supply, using a harvest rotation based on minimum merchantable age (approximately 100 years in this analysis), creates a trend for the stand age-class distribution away from the expected range of natural variation for the study area.
For an organism, no matter what it belongs to, either animals or plants, the essential materials that the organism needs for sustaining its livingness are supplied and transported through space-filling fractal networks of branching tubes, which are of self-similarity and underlie the metabolic process of an organism [15].
As a result, supplies of energy necessary for sustaining civilizations eventually will dwindle.
A constant, copious supply of oxygen is required for sustaining the active, heat-producing (endothermous) physiology of the higher vertebrates.
Judicious management of organic matter supply and tillage practice is crucial for sustaining soil quality in horticulture.
The supply of oxygen to gas exchange tissue is critically important for sustaining the metabolic rate of an animal.
