Heterogeneity in Ty1-copia group of retroelements in chickpea (Cicer arietinum) genome

Retrotransposons constitute a major fraction of plant genomes and these elements may have played a significant role in evolution and sequence organization of genomes. In order to access the diversity of Ty1-copia group of retroelements, reverse transcriptase (RT) sequences were amplified from chickpea genome, using the primers derived from two conserved domains of RT region. Thirty-six RT regions from independent amplicons were cloned and sequenced. On the basis of homology of deduced amino acids, the RT sequences could be grouped into three major families. The intra-family divergence at amino acid level ranges from 2 to 19%. Though intra-family RT sequences were conserved but no two sequences were identical. The results indicate a high degree of heterogeneity among the Ty1-copia group of retroelements from chickpea. It was possible to isolate RT specific sequences from RNA isolated from stressed seedlings, indicating that some of the retroelements may be functional under certain stress conditions

Energy Transformations in a Relativistic Engine

In a previous paper we have shown that Newton's third law cannot strictly hold in a distributed system of which the different parts are at a finite distance from each other. This is due to the finite speed of signal propagation which cannot exceed the speed of light at vacuum, which in turn means that when summing the total force in the system the force does not add up to zero. This was demonstrated in a specific example of two current loops with time dependent currents, the above analysis led to suggestion of a relativistic engine. Since the system is effected by a total force for a finite period of time this means that the system acquires mechanical momentum and energy, the question then arises how can we accommodate the law of momentum and energy conservation. The subject of momentum conversation was discussed in a previous paper, while preliminary results regarding energy conservation were discussed in previous papers. Here we give a complete analysis of the exchange of energy between the mechanical part of the relativistic engine and the field part, the energy radiated from the relativistic engine is also discussed. We show that the relativistic engine effect on the energy is 4th-order in 1/c and no lower order relativistic engine effect on the energy exist.Comment: 68 page

A REPRISE OF SUPPLY CHAIN MANAGEMENT IN CONSANGUINITY TO THE INDUSTRY OF TEXTILE

This study investigates supply chain management (SCM) literature to categorize it as well as this study particularly explores studies of SCM for textile industry. An analysis is provided for SCM in connection to textile industry. Science Direct, ABI/INFORM Global, EBSCO Host, and Emerald scholarly databases are inspected for SCM studies. It is found that there is lack of agreement for a sole definition of SCM; moreover, textile industry is being neglected for investigation of SCM. However, categories of SCM are described in a descending order from most studied categories to least studied categories. There is a void of a sole definition for SCM; therefore, a comprehensive definition of SCM is suggested from pertinent literature. Moreover, research gaps are identified for future research of SCM particularly for textile industry.supply chain management, textile industry, categories of SCM
