The lignin degradation and its structural change as a result of catalytic steam Compartment Sinks explosion pretreatment can be considered of great importance for both the subsequent fermentation and the further utilization of the lignin fraction.This work investigated the degradation mechanism and change in the characteristics of lignin during dil
Geological materials usually contaminated with naturally occurring radioactive materials (NORM) have become a focus of great attention.The radioactivity concentrations of 226Ra, 232Th and 40K in some ornamental stones in Egypt, were measured using a high-resolution gamma ray spectrometer.The Training Vests natural radionuclide contents, (Ra) equiva
Double-layer Ni-P coatings with low phosphorus content in the inner layer and high phosphorus content in the outer layer and Ni-Mo-P composite coatings are successfully prepared on MIMULUS the surface of AZ91D magnesium alloy by chemical plating process.The microstructures, friction and corrosion resistance of double-layer Ni-P and Ni-Mo-P coatings
BACKGROUND:Polymorphism of major histocompatibility complex (MHC) genes ensures effective immune responses against a wide array of pathogens.However, artificial selection, as performed in the case of domestic animals, may influence MHC diversity.Here, we investigate and compare the MHC diversity of three populations of horses, for which different b
Transmit beamforming (TBF) has been proposed as an effective approach to enhance the security performance of multiple-input single-output (MISO) wiretap channels.However, this secrecy enhancement comes at some expenses, such as power consumption and the amount of signal processing.In addition, in block fading channels, TBF fails to deliver secure c
