background: nematodes are among the most common and important parasites of man and animal. dna of a single worm can be used for several purposes, such as identification to the species, subspecies, strain and antihelmenthic resistance. dna extraction from a single small worm using traditional methods such as phenol extraction technique faces serious prob lems. methods: dna from 20 single haemonc...

The possibility of selective leaching process was investigated during molybdenite flue dust leaching to recover its rhenium content. The results show that addition of alcohols to water makes the medium less favorable for molybdenum transfer into aqueous phase. On the other hand, addition of small amounts of alcohols (5-15%) makes a noticeable separation of rhenium over molybdenum, but by increa...

Due to its high thermal conductivity and favorable machinability, molybdenum–rhenium (Mo–Re) alloys have huge prospects in the field of high-temperature heat pipes. However, weldability Mo–Re has not yet been systematically investigated. Based on an orthogonal test, influence law single-mode fiber laser welding parameters weld profile mechanical properties joints was studied. Furthermore, exist...

Integrating information from different stages of an NLP processing pipeline can yield significant error reduction. We demonstrate how re-ranking can improve name tagging in a Chinese information extraction system by incorporating information from relation extraction, event extraction, and coreference. We evaluate three stateof-the-art re-ranking algorithms (MaxEntRank, SVMRank, and p-Norm Push ...

A molybdenum-iron cluster (Mo-Fe cluster) containing 6 Fe atoms per Mo was isolated by methyl ethyl ketone extraction of component I of nitrogenase from Azotobacter vinelandii. The cluster has no EPR signal in the g = 4 region but has an intense signal at g = 2.05 and 2.01. After the cluster was transferred from methyl ethyl ketone to N-methylformamide, the signal in the g = 2 region disappeare...
