Pump systems

Solar energy, light and heat radiation from the Sun, has been exploited by humans since ancient times using a variety of technology development than ever before. Solar radiation along with secondary resources of energy like wind and solar energy, water power and biomass, make the most of renewable energy available on earth. Only a tiny fraction of the available solar energy is used.

The goal is to pump 15 m3/day of water to cover the student services building needs. The test after installation showed that the pumping flow rate of 0.2 L/sec has been achieved; this result shows that the designed and manufactured wind pumping system can pump more than the record which allows storage of water.

This paper explains how to convert the lost energy through exhaust system in internal combustion engines “ICE” to electric energy by using thermoelectric generators "TEG" with the benefit of the equipment’s which are already existed in most of the internal combustion engines such as water pump, heat exchanger, and exhaust system.

The vacuolar H + -ATPase (V-ATPase) is a multimeric enzyme complex that acidi®es organelles of the vacuolar system in eukaryotic cells. Proteins that interact with the V-ATPase may play an important role in controlling the intracellular localization and activity of the proton pump. The neuroendocrine-enriched V-ATPase accessory subunit Ac45 may represent such a protein as it has been shown to interactwith themembrane sector of theV-ATPase inonlya subset of organelles.

The spontaneous acquisition of resistance to a variety of unrelated cytotoxic compounds has important implications in medical treatment of infectious diseases and anticancer therapy. In the yeast Saccharomyces cerevisiaethis pheno-menon is caused by overexpression of membrane efflux pumps and is called pleiotropic drug resistance. We have found that allelic forms of the genes for the transcription activators Pdr1p and Pdr3p, designated PDR1-12and PDR3-33,respectively, mediate resistance to diazaborine....

The unique family of membrane-bound proton-pumping inorganic pyro-phosphatases, involving pyrophosphate as the alternative to ATP, was investigated by characterizing 166 members of the UniProtKB⁄Swiss-Prot + UniProtKB⁄TrEMBL databases and available completed genomes, using sequence comparisons and a hidden Markov model based upon a conserved 57-residue region in the loop between transmembrane segments 5 and 6.
