Los recursos hídricos son vitales para la vida y el desarrollo económico, pero en Colombia están amenazados por externalidades negativas de diversos sectores económicos. La protección los depende fundamentalmente calidad efectividad regulación ambiental parece ser un punto referencia internacional institucionalización ambiental, dada su exhaustividad e integralidad. Sin embargo, colombianos han...

Abstract To reduce the energy consumption of nuclear power plants, this paper studies control mode changing condensate pump frequency to variable speed regulation, using permanent magnet flexible transmission technology change pump, and strategy deaerator water level outlet pressure is redesigned achieve purpose saving. Through study strategy, process design analysis, theoretical calculation, s...

Head-out water immersion at thermoneutral temperature (34-35 degrees C) increases cardiac output for a given O2 consumption, leading to a relative hyperperfusion of peripheral tissues. To determine if subjects immersed in water at a colder temperature show similar responses and to explore the significance of the hyperperfusion, cardiovascular functions were investigated (impedance cardiography)...

The role of histamine in the regulation of food and water intake in mammals and birds of the review, this study evaluated the effects of intraperitoneal administration of famotidine as histamine H2 -receptor antagonist, in broiler chicks on feed intake and satiety in water and was hungry. 32 male Ross broiler chicks reared in groups of four weeks, 16 samples (control and test ) were then inject...

TO INCLUDE a discussion of the regulation of total body water and electrolytes in such a symposium OIn the cardiovascular system at first glanee may require some justification. It should be quickly apparent, however, that the total body fluids and the circulatory system are so intimately interrelated that consideration of one without the other would be quite incomplete. Part of the body fluids,...
