sweet sorghum that is adapted to the country hot and dry climatic condition, was selected as a raw material for biofuel and biogas production. bioethanol is produced from sweet sorghum stalks and grains and biogas is produced from its byproducts. the purpose of this study was to plant sweet sorghum irrigated with different qualities of water in order to produce biofuels. this experiment was con...

Sixty years after the seminal Miller-Urey experiment that abiotically produced a mixture of racemized amino acids, we provide a definite proof that this primordial soup, when properly cooked, was edible for primitive organisms. Direct admixture of even small amounts of Miller-Urey mixture strongly inhibits E. coli bacteria growth due to the toxicity of abundant components, such as cyanides. How...

In recent years attention of the specialists in different fields of biomedicine has focus on an unusual phenomenon, i.e., many so-called “non-endocrine” cells in living organism produce hormones. In addition to neurons and some types of lymphocytes for which such ability was shown earlier [1–2], a large number of other cells significantly extend this list today. Among them, mast cells, natural ...

This paper describes the methods used to specify and implement a camplex communicatioas protacd that prwides reliable delivery of data in multicastcapable. packet-switching telecrmmuniatim networks. The protocol. called the Reliable Multicasting Protocol @IMP). was developed inmenta l ly by two ccrnplementary teams using a cmbiiatim of f m a l and infama1 techniques in an attempt to ensure the ...

The angular clustering of 5 Ultrahigh Energy Cosmic Rays (UHECRs) in the combined published AGASA-HiRes data has a probability of ∼ 2×10 of occurring by chance. A first analysis of the implications of the event energies and angular spreading is presented, which is applicable if the source is close enough that GZK losses can be ignored. Under this assumption, the observed energies of the events ...
