Marine streptomycetes are rich sources of natural products with novel structures and interesting biological activities, and genome mining of marine streptomycetes facilitates rapid discovery of their useful products. In this study, a marine-derived Streptomyces sp. M10 was revealed to share a 99.02% 16S rDNA sequence identity with that of Streptomyces marokkonensis Ap1T, and was thus named S. m...

Intracellular expression of gene products that inhibit viral replication have the potential to complement current antiviral approaches to the treatment of AIDS. We previously have shown that a mutant inhibitory form of an essential viral protein, Rev M10, prolongs the survival of T cells transduced with a nonviral vector in HIV-infected individuals. Because these gene-modified cells were not ob...

The human immunodeficiency virus (HIV) Rev protein is essential for viral structural protein expression (Gag, Pol, and Env) and, hence, for viral replication. In transient transfection assays, mutant forms of Rev have been identified that inhibit wild-type Rev activity and therefore suppress viral replication. To determine whether such transdominant Rev proteins could provide long-term protecti...

Figure 1, compiled from data in the US Geological Survey indicates that, in 2004, 94% of vanadium used was consumed by the steel industry and 6% by all other uses. Figures 2 and 3 show data on steel production and vanadium consumption over a number of past years. Figure 2 indicates that in 2004 steel production reached a record level of 1.036 billon tonnes, driven largely by increases in steel ...

 Beijing’s industrial structure is service-oriented with a high degree of economic openness, and GDP has maintained rapid growth. This paper analyzes the international financial crisis and the impact of China’s anti-crisis policies on Beijing’s economic development as well as its transmission mechanism. Impact Index (excluding seasonal factors) and ARMA Model are employed in the empirical...

Steel industry is one of the leading industries in the world. Today it is also one of the fundamental and strategic industries of the world. Per capita production and consumption amount of steel are used as a criterion for evaluation of country development. Furthermore, attention to technological innovations is assumed so much crucial to access the international markets of steel industrie...

Environmental degradation and Economic growth are two important proofs in sustainable development which are followed by steel industry. In this case, energy and environmental damages as sustainability patterns of environment have been investigated in three different dust collectors to select the most environmentally suitable dust collector for electric furnace. In this article, the consumption ...

cost reduction is one of the methods applied for improving the productivity of organizations. in productivity literature, particularly in nonparametric methods, cost reduction related methods are regarded as input oriented models. this paper presents a supply chain management (scm) model in which purchasing iron ore and coke from different resources, along with production and distribution of st...

Steel surface defect detection is essentially one of pattern recognition problems. Support Vector Machines (SVMs) are known as one of the most proper classifiers in this application. In this paper, we introduce a more accurate classification method by using SVMs as our final classifier of the inspection system. In this scheme, multiclass classification task is performed based on the ”one-agains...
