The carcinogenicity of 3-chloro-2-methylpropene (CMP), a chemical intermediate and insecticide, was studied because of possible human exposure and because of its structural relationship to vinyl chloride and allyl chloride. CMP in corn oil was administered by gavage to groups of 50 male and 50 female Fischer 344/N rats at 0, 75, or 150 mg/kg body weight and to groups of 50 male and 50 female B6...
برای بهبود ویژگی های مختلف خمیرکاغذ cmp گونه سپیدار از خمیرکاغذ مرکب زدایی شده مخلوط کاغذهای باطله اداری استفاده شد. خمیرکاغذ cmp براساس شرایط استاندارد صنعتی (چوب و کاغذ مازندران) و خمیر dip مخلوط کاغذ باطله اداری به روش شناورسازی تهیه شد. بعد از رساندن درجه روانی خمیرهای کاغذ یاد شده به حدود 300، از آن ها در اختلاط با خمیر الیاف بلند وارداتی کاغذهای دست ساز ساخته شد و ویژگی های فیزیکی، مکانیک...
As the increasing of issue width has diminishing returns with superscalar processor, thread parallelism with a single chip is becoming a reality. In the past few years, both SMT (Simultaneous MultiThreading) and CMP (Chip MultiProcessor) approaches were first investigated by academics and are now implemented by the industry. In some sense, CMP and SMT represent two extreme design points. In thi...
Bacterial α(2,6)-sialyltransferases (STs) from Photobacterium damsela, Photobacterium sp. JT-ISH-224, and P. leiognathi JT-SHIZ-145 were recombinantly expressed in Escherichia coli and their ST activities were compared directly using a galactosylated bi-antennary N-glycan as an acceptor substrate. In all ST reactions, there was an increase of sialylated glycans at shorter reaction times and lat...
PURPOSE Cerebral misery perfusion (CMP) is a condition where cerebral autoregulatory capacity is exhausted, and cerebral blood supply in insufficient to meet metabolic demand. We present an educational review of this important condition, which has a range of clinical manifestations. METHOD A non-systematic review of published literature was undertaken on CMP and major cerebral artery occlusiv...
Problem statement: Abrasive is one of key influencing factors on the polished surface quality in Chemical Mechanical Polishing (CMP). Solid abrasives in CMP slurries are easy to cause polishing scratches. It is well known that reducing the hardness of abrasives would improve the polished surface quality. Therefore, the change in structure or shape of the abrasives means a change in polished sur...
A production worthy, copper CMP technology has been successfully developed on a multi-platen CMP system. The System consists of three polish platens, each of which is equipped with an optical endpoint detection system. The process consists of three steps with different polish slurries, and is designed to polish copper with a tantalum based barrier, and to achieve good defect performance. Patter...
Modified pyrimidine monophosphates such as methyl dCMP (mdCMP), hydroxymethyl dUMP (hmdUMP) and hmdCMP in some phages are synthesized by a large group of enzymes termed as thymidylate synthases (TS). Thymidylate is a nucleotide required for DNA synthesis and thus TS is an important drug target. In the biosynthetic pathway of the nucleoside fungicide mildiomycin isolated from Streptomyces rimofa...
