one of the most important aspects in recombinant biologic production, based on gmp rules, is the accuracy of final product quality control, especially assessment of host cell macromolecules contamination rate in final product. the purification requirement can be eliminated when the yeast cell containing the recombinant protein is used as a host cell. it is possibile that the final product conta...

Commercial open source software projects are open source software projects that are owned by a single firm that derives a direct and significant revenue stream from the software. Commercial open source at first glance represents an economic paradox: How can a firm earn money if it is making its product available for free as open source? This paper presents the core properties of commercial open...

The modern U.S. “market” for weapons and weapon systems has two dominating features. First, it is characterized by a single buyer, DoD, which defines the product and controls the sales opportunities of weapon system providers.2 Unlike most commercial product markets, the weapons market is centralized, historically driven by the detailed performance and technical requirements provided by DoD.3 E...

abstract bee venom is a complex mixture of proteins, peptides and low molecular components: proteins (enzymes) :( phospholipase, a2phospholipase b, hyaluronidase α – glucosidase) - , peptides (melittin, apamine mcd peptide,adolapine ,procamine a and b, protease inhibitors)- low molecular components: biogenic amines:( histamine, dopamine and noradrenalin) - pheromones: complex ethers- sugars :( ...

A simple method for the synthesis of octahydroquinazolinone derivatives in the presence of BF3.SiO2 and Insecticide activity of these compounds against spodoptera litura was investigated to be comparable to commercial pyrethroid insecticides, Cypermethrin and Cyhalothrin. The structure of the isolated compounds was characterized by 1HNMR and FT-IR spectroscopy.The proposed method had some ad...
