Biotransformations are structural modifications in a chemical compound by organisms /enzyme systems that lead to the formation of molecules with relatively greater polarity [1,2]. This mechanism has been developed by microbes to acclimatize to environmental changes and it is useful in a wide range of biotechnological processes [3]. The most significant aspect of biotransformation is that it mai...

In this chapter, we derive the partial-differential equations that govern fluid motion and make a series of simplifications and modifications to adapt them to environmental applications. The differential approach is exposed in addition to the control-volume approach of the previous chapter because it is better suited to certain applications, particularly the study of waves and instabilities. Th...

The social environmental barriers are considered to be important because the "social participation" of people with impairments would be facilitated by the prevention and reduction of environmental barriers. The Craig Hospital Inventory of Environmental Factors (CHIEF) is one of the few scales to assess the environmental barriers. In this study, we developed the Korean version of CHIEF and evalu...

Introduction: The Parachute Acrobatic Patrol of the Air Force (PAPEA) is an international elite team in this sport. The environmental conditions in which they do his work; 3-4 daily jumps from 2300-11000 feet, the speed of their bodies during the free fall, the abrupt changes of altitude, and also temperature and atmospheric pressure can produce modifications in their bodily composition and lev...

Regulation of gene expression is a key event during development, differentiation, signaling, and adaptation to environmental cues. Gene expression is regulated at many levels. Histone modifications and binding of transcription factors to their cognate target sites in promoters and enhancers lead to the recruitment of activating or repressing cofactors and ultimately in alteration of mRNA levels...

• Changes in community composition resulting from climate change entail modifications of biotic interactions and reshape local species distributions. Such changes are currently occurring in nettle-feeding butterflies in Sweden where Araschnia levana has recently expanded its range northward and is now likely to interact with the resident species (Aglais urticae and Aglais io). Butterfly occurre...

In a memorandum dated November 25, 1997, NRR requested RES to perform appropriate research and provide independent confirmation of the applicability of Arrhenius methodology to meet the environmental qualification (EQ) requirements for LOCA and post-LOCA environments. RES was requested to support the NRR reviews of licensees' requests for (1) power uprate amendments, (2) reevaluation of qualifi...

The principles of amputee rehabilitation, from preamputation to reintegration into the work force and community, are reviewed. The authors discuss exercise techniques, training programs, and environmental modifications that have been found to be helpful in the rehabilitation of the amputee. The exercise programs presented here are divided into four main components: flexibility, muscle strength,...
