analysis of power in the network society
اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
YtsCD and YwoA, two independent systems that confer bacitracin resistance to Bacillus subtilis.
The Bacillus subtilis yts, yxd and yvc gene clusters encode a putative ABC transporter and a functionally coupled two-component system. When tested for their sensitivity towards a series of antibiotics, null yts mutants were found to be sensitive to bacitracin. Real-time polymerase chain reaction (PCR) experiments demonstrated that the presence of bacitracin in the growth medium strongly stimul...
متن کاملBacitracin upregulates mbrAB transcription via mbrCD to confer bacitracin resistance in Streptococcus mutans.
Streptococcus mutans is a bacterial cause of dental caries that is resistant to bacitracin. The aim of this study was to elucidate the mbrABCD-related bacitracin resistance mechanism of S. mutans. Transcriptome data demonstrated that the expression levels of 33 genes were induced more than twofold by bacitracin. Fourteen genes were selected from the upregulated genes, and defective mutants of t...
متن کاملEngineered biosynthesis of the peptide antibiotic bacitracin in the surrogate host Bacillus subtilis.
Nonribosomal peptides are processed on multifunctional enzymes called nonribosomal peptide synthetases (NRPSs), whose modular multidomain arrangement allowed the rational design of new peptide products. However, the lack of natural competence and efficient transformation methods for most of nonribosomal peptide producer strains prevented the in vivo manipulation of these biosynthetic gene clust...
