cultivating people for preventing environmental destruction
the fundamental elements of nature, namely earth, water, air and sunshine should be in a healthy state, well balanced with the criteria of equilibrium and untainted so that the environment would remain pleasant and lively. hence, there will be plant, animal and human in a existential balance. man himself is the major polluter and destructor of environment. the environment, in turn, is a large c...
متن کاملUbiquitination: RING for destruction?
Targeted protein proteolysis is increasingly understood to be an important general mechanism by which cells regulate protein levels — and consequently their functions at specific times. In eukaryotic cells, the main mechanism for such control involves the specific covalent modification by polyubiquitin, which labels target proteins for proteolysis and subsequent degradation. There are many know...
متن کاملTissue Engineering for Blood Vessels
The artificial vascular grafts currently in clinical use still have problems with respect to late calcification, restenosis, antithrombotic property, durability, biocompatibility, and safety, and no ideal artificial vascular graft has been developed to date. In view of this, we have been continuing basic experimental studies and their clinical applications in an attempt to develop tissue-engine...
متن کاملProposing a Novel Configuration for CGSs Aimed at Reducing Energy Consumption and Exergy Destruction
A CGS is of the most important parts in natural gas transmission pipelines in which the high inlet natural gas (NG) pressure is reduced to much lower value by employing a throttling valve. This pressure drop causes hydrate forming, preventing stable NG flow through the pipeline. To prevent hydrate forming, NG is usually preheated by heaters which burns remarkable amount of NG. In this work, a n...
متن کاملSystemic destruction
Cristae in crisis ristae, the complex involutions of the mitochondrial inner membrane, vastly increase the surface area across which ATP synthase can generate a proton gradient. Now, new findings from Jean Velours (Université Victor Ségalen, Bordeaux, France) and colleagues suggest that ATP synthase may be important in forming cristae in the first place. Velours' theory is that oligomerization ...
