background: the values of embryonic stem cell and cloning are evident. production of clone from embryonic stem cells can be achieved by introduction of stem cell into a tetraploid blastocyst. tetraploid blastocyst can be produced in vitro by electrofusion of 2-cell embryos. objective: the aim of this study was to assess the effect of different voltages and durations on fusion rate of bovine 2-c...

Complex networks have been a prominent topic of research for several years, spanning wide range fields from mathematics to computer science and also social biological sciences. The eigenvalues the Seidel matrix, Signless Laplacian energy, Maximum Minimum Degree Sum energy Distance Unitary Cayley graphs [UCG] calculated. Low-power devices must be able transfer data across long distances with low...

We explore the consequences of layering a Lambek proof system over an arbitrary (constraint) logic. A simple model-theoretic semantics for our hybrid language is provided for which a particularly simple combination of Lambek's and the proof system of the base logic is complete. Furthermore the proof system for the underlying base logic can be assumed to be a black box. The essential reasoning n...

Background: Bacterial mastitis in cows is a huge challenge to the dairy cattle breeding and production industry. This study examined relationship between bacterial diversity at different sampling sites farms. Methods: High-throughput sequencing of 16S rRNA V4 region was used analyze abundance population sampled from seven farm, named healthy cow milk (N), (C), perimammary (T), collecting cup (B...

Underground coal gasification (UCG) technology converts deep resources into synthesis gas for use in the production of electricity, fuels and chemicals. This study provides an overview systematic methods situ process. Furthermore, model porous structure has been presented movement taking place carbon matrix—which is part bed—has described. The experimental tests were carried out with air forced...

Recently, multi-frequency multi-constellation receivers have been actively studied, which are single that process multiple global navigation satellite system (GNSS) signals for high accuracy and reliability. However, in order a receiver to GNSS signals, it requires as many code generators the number of supported this is one problems must be solved implementing an efficient receiver. This paper ...
