این تحقیق با هدف بررسی تولید خمیرکاغذ بی‌سولفیت از گونۀ ممرز به‌منظور تقویت ویژگی‌های مقاومتی خمیرکاغذ CMP انجام گرفت. خمیرکاغذ CMP براساس شرایط استاندارد صنعتی (شرکت صنایع چوب و کاغذ مازندران) و خمیرکاغذ بی‌سولفیت با استفاده از تزریق مستقیم گاز دی‌اکسید گوگرد به محلول هیدروکسید سدیم در آزمایشگاه تهیه شد. نتایج پخت خمیرکاغذ بی‌سولفیت نشان داد که با افزایش زمان پخت از 1 به 3 ساعت، بازده و عدد کا...
During aerobic respiration, Bacillus subtilis utilizes three terminal oxidases, cytochromes aa3, caa3, and bd. Cytochrome bd is encoded by the cydABCD operon. We report here the first identification of a regulator for the cydABCD operon, YdiH. While working with DeltaresDE mutant strains, we identified colonies which contained suppressor mutations (cmp) which bypassed the requirement for ResD f...
Unlike human erythrocytes, those from avian species, such as turkeys and chicks, rapidly incorporate myo-[3H]inositol into membrane phospholipids. The mechanisms regulating [3H]Ins labelling of phosphatidylinositol have been investigated using turkey erythrocyte membranes. In the absence of added nucleotides, [3H]inositol incorporation appears to proceed via phosphatidylinositol/inositol exchan...
The aim of the present work is to obtain a chemical-mechanical pulp (CMP) from poplar wood with improved properties, to be used in packing papers in place of more expensive softwood or hardwood pulp. For improving the CMP quality indicators, a preliminary treatment of the pulp has been carried out with a mixture of oxidizing enzymes produced from Phanerochaete chrysosporium, including lignin pe...
Chemical mechanical polishing (CMP) is a key process enabling shallow trench isolation (STI), which is used in current integrated circuit manufacturing processes to achieve device isolation. Excessive dishing and erosion in STI CMP processes, however, create device yield concerns. This thesis proposes characterization and modeling techniques to address a variety of concerns in STI CMP. Three ma...
Neisseria gonorrhoeae deploys a novel immune evasion strategy wherein the lacto-N-neotetraose (LNnT) structure of lipooligosaccharide (LOS) is capped by the bacterial sialyltransferase, using host cytidine-5'-monophosphate (CMP)-activated forms of the nine-carbon nonulosonate (NulO) sugar N-acetyl-neuraminic acid (Neu5Ac), a sialic acid (Sia) abundant in humans. This allows evasion of complemen...
Chemical-mechanical planarization (CMP) is an enabling technique to achieve uniformity of dielectric and conductor height in BEOL manufacturing processes. Dummy fill insertion improves the uniformity of metal feature density and enhances the planarization that can be obtained by CMP, but can also change the coupling and total capacitance of interconnects [1], [2]. Additionally, dishing and eros...
human immunodeficiency virus (hiv) infection has been associated with cardiac disease, including anatomical or functional disturbance to the heart. cardiomyopathy (cmp) is one of these disturbances that have been associated with high rates of morbidity and mortality. in this review article, several aspects of potential relationships between hiv infection and cardiomyopathy development have been...
On-Line Transaction Processing (OLTP) workload is an important application in commercial service domain. Chip multiprocessor (CMP) is main stream of processor development. Performance characters of OLTP in CMP become a crucial benchmark for design and performance analysis of CMP server system. System level performance characters of OLTP on AMD quad-core system is presented in the paper. Accordi...
We report about an infant affected by dilated cardiomyopathy (CMP) in whom metabolic investigations evidenced medium-chain-acyl-CoA dehydrogenase deficiency (MCADD), that is one of three types of inherited disorders of mitochondrial fatty-acid beta-oxidation. Long-chain and very long-chain 3-hydroxyacyl-coenzyme A dehydrogenase deficits are recognized as responsible of hypertrophic or, less fre...
