Understanding of amino acid type co-occurrence in trusted multiple sequence alignments is a prerequisite for improved sequence alignment and remote homology detection algorithms. Two objective approaches were used to investigate co-occurrence, both based on variance maximization of the weighted residue frequ...
(photovoltaic) cell converts photons from the sun (solar light) into electricity (photovoltaic effect) through different steps: (i) light absorption and generation of electron–hole pairs or excitons; (ii) separation of charge carriers (electron–hole pairs); and (iii) separate extraction of ...
CRISPR-Cas mediated DNA-interference typically relies on sequence-specific binding and nucleolytic degradation of foreign genetic material. Type IV-A CRISPR-Cas systems diverge from this general mechanism, using a nuclease-independent interference pathwa
Objective To establish a method to determine 16 types of organochlorine pesticides(OCPs) in soil samples through ultrasonic extraction-gas chromatography.Methods Samples were extracted with organic solvent(volume of acetone: volume of hexane=1∶1) by using ultrasonic extraction which was then combined ...

Types of Ore Lesson Summary Frequently Asked Questions What are some examples of ore? Ore comes in many different types which are classified based on the way they are formed as well as the minerals found within them. Examples of ores mined for the extraction of copper include chalcopyrite, ...
lowering effect of two types of phytosterol nanoparticles was determined by analyzing the average body weight and the daily food intake of the mice,the serum biochemical indices,the organ indices,the hepatic fat contents,the sterol contents in the feces and histological observation of liver slices. ...

These characteristics suggest that harzburgite 3816 comes from mantle which was subjected to significant melt extraction. The absence of clinopyroxene points to high a degree of partial melting, since this mineral disappears at ~25% partial melting (e.g. Walter, 1998). Negative Ti, Zr and Hf ...
