Of the various insect species silk producing  insects  which includes Bombyx mori and Antherae mylitta are very famous as these are highly beneficial to the mankind. They produce silk which is worldwide recognized as the Queen of fibres. The demand of silk is increasing in the world day by day and therefore many scientists are involved to increase the production and productivity of silk by using latest technologies. .

Fibre is a thread like substance used in textile industry for the production of goods or provision of services. Two major groups of textile fibres are natural & synthetic. Natural Fibres are subdivided into animal, vegetable and mineral fibres. All animal fibres are proteins, all vegetable fibres are cellulose, all mineral fibres are mineral based. Eg:-Silk, cotton, wool, linen, jute etc. Natural fibres tend to have complex and distinctive internal and external features. Natural fibres have variable diameter, cross section and possibly color banding.

Entropy and absolute temperature, both involved in Carnot’s cycle, imply that time and social constructivism of thermodynamic processes produce sufficient support for reconciling the threefold time emergence: (i) time as  a 1D manifold, (ii) the asymmetric thermodynamic, and (iii) the evolutionary  asymmetric time. Is time whether emerging from entropy as reality with three  different faces or does it mean that we have to manage three different  realities emerging from heat transformation? We put forward three steps. Firstly, we start from a triad of time.

A survey was conducted for the observation of orchid pests in different districts of Manipur.

The international sanctions are imposed against Russia following Russia's annexation of Crimea and the Russian military intervention in Ukraine. This paper aims are at analyzing the impact of sanctions on Russian economy and on energy security of European Union (EU) countries. The focus is energy trade between the EU and Russia. Energy security is always one of the most important problems for the EU.

This paper described isolation and identification of the bioflocculant producing bacteria from soil samples of Tay Nguyen region, Vietnam. A total of 117 bacteria were isolated, among of which 26 isolates showed flocculating activity more than 50%. In addition, the influence of carbon and nitrogen sources, as well as cultural conditions such as temperature, pH and incubation time on flocculating activity of the 3 selected flocculant producing isolates were investigated.

This paper determines the perception of senior high youth about sexuality, for which an instrument containing a demographic profile and socio sexual behavior through items in a liker scale was applied.

Through the use of the structures of greenhouses which used to grow vegetables, in addition to the design of simple models of the structures with local materials to cultivate some fruit crops are very important in terms of economic consideration, which can be exported in large quantities to foreign markets such as navel orange and some pygmy mango varieties. The study was carried out at the Bossaily Protected Agriculture unit in Egypt to measure the performance, efficiency of production and the revenue during the cultivation period 2007- 2013.

This paper investigates the application of the generalized predictive control (GPC), in order to control the speed of the induction motor. This application is based on four main ideas :  reproducing decision basic mechanisms of human behaviour; the creation  of  an  anticipatory  effect  by  operation  of  the  path  to  follow  in  the  future;  defining  a  numerical  prediction  model; minimization of a quadratic criterion with finite horizon and the principle of receding horizon.

The evaluation of the antibacterial activity using five bacterial strains (Klebsiella, Shigela, Salmonella, Escherichia coli and Staphylococcus aureus) showed that the most active leaf extract was that of Odontonema strictum (Acanthaceae) compared to that of Solanum torvum, Symphytum officinale L. and Aphelandra squarrosa. The inhibition diameters were measured and no resistance was observed at the concentration of 100 g/ml across all bacterial strains.  The Activity Index (AI) values of Odontonema strictum (OSM) were determined using chloramphenicol as a positive standard antibiotic.
