many large oil and gas fields in the most productive world regions happen to be fractured. the exploration and development of these reservoirs is a true challenge for many operators. these difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. to successfully address these challenges, it is paramount to improve ...

The need for alternative and environmental friendly methods of waste clean-up has led to the use enzymes in bioremediation. In this study, white rot fungi were isolated from decaying plant parts using standard microbiology biochemical techniques. fungal mycelial identified screened substrates (2, 6-DMP) determine their capability production Manganese peroxidase. Pure manganese peroxidase was ac...

A procedure is described for obtaining DNA-dependent RNA polymerase form B from calf thymus in high purity. The procedure includes homogenization in low salt, sedimentation of chromatin at 50 000 x g, adsorption to DEAE-cellulose in a batch procedure, DNA-agarose chromato­ graphy, and chromatography on DEAE-Sephadex. Analyses of the preparation by band sedimenta­ tion and gel-electrophoresis in...

STREAMLINE aims for improving the overall workflow of big data analytics systems. For this goal, it combines research in different areas to reduce the complexity of the work with data at rest and data in motion in a unified fashion. As a foundation STREAMLINE offers a uniform programming model on top of Apache Flink, for which it drives innovations in a wide range of areas, such as interactive ...

Introduction: Neighborhood tractography offers the potential to improve the reliability and reproducibility of automated white matter pathway extraction and associated measurements of connectivity and tract integrity. Neighborhood tractography frameworks have been proposed for local tractography methods, particularly those based on streamline, or probabilistic streamline algorithms [1,2]. In th...

background: in this study we have prepared the iga solution from normal human plasma using plasma fractionation and ion exchange chromatography. materials and methods: using fractionation of plasma with cold ethanol (starting with 8% ethanol), fraction iii was prepared as a suitable source for iga preparation. then it was treated with caprylic acid for separation of impurities. for enrichment o...

Currently, there are no methods of visual analysis for ensemble vector fields (EVF) that provide identification of flow trends and general flow similarity over the extent of transport across ensemble members. Finite-time Variance Analysis (FTVA) provides flow structure information only on particle distributions at the termination of streamline integration. In this paper, we first present a flow...
