The ability of 223 Type II restriction endonucleases to hydrolyze RNA-DNA heteroduplex oligonucleotide substrates was assessed. Despite the significant topological and sequence asymmetry introduced when one strand of a DNA duplex is substituted by RNA we find that six restriction enzymes (AvaII, AvrII, BanI, HaeIII, HinfI and TaqI), exclusively of the Type IIP class that recognize palindromic o...

The aim of this study was isolation and identification fungi producing aflatoxin B1 from wheat which stored for four months in some silos Baghdad , including Al Taji Silo, Khan Bani Saad Silo Dhari Silo. Those Silos were included the agricultural plan marketing season 2020. Different types obtained. They initially identified according to cultural morphological characteristics as Alternaria spp,...

Using time series of Normalized Difference Vegetation Index (NDVI) and rainfall data, we investigated historical vegetation productivity trends from 1982 to 2011 over the Bani River Basin in Mali. Statistical agreements between long-term trends in vegetation productivty, corresponding rainfall and rate of land cover change from Landsat time-series imagery was used to discern climate versus huma...

It is difficult to assess pollution in remote areas of less-developed regions owing to the limited availability of energy, equipment, technology, trained personnel and other key resources. Passive sampling devices (PSDs) are technologically simple analytical tools that sequester and concentrate bioavailable organic contaminants from the environment. Scientists from Oregon State University and t...

The aim of this research is to optimize the power generation a wind farm (WF) in order maximize energy output, especially low speeds regions such as UAE. A new WF was proposed be built Sir Bani Yas Island This project chosen act main case configuration for research. Four parameters were and assessed follows: (1) inserting smaller turbines between original larger turbines; (2) changing spacing (...

Abstract BaNi 2 As is a non-magnetic analogue of BaFe , the parent compound prototype pnictide high-temperature superconductor, displaying superconductivity already at ambient pressure. Recent diffraction studies demonstrated existence two types periodic lattice distortions above and below triclinic phase transition, suggesting an unconventional charge-density-wave (CDW) order. The suppression ...
