Today, transportation is one of the substructure parts of society that not only affects the economical growth process, but also is changed in development. The transportation substructure is one of the substructure parts of services has an important position in the economical development of countries. An efficient and appropriate transportation network causes goods transportation and services co...

the nutritional requirements of mammalian embryos changes throughout pre-implantation period, coincident with changes in the secretion of the female reproductive tract. therefore, it has been suggested that sequential culture media may support nutritional requirements for optimal growth of the mammalian embryos. in this study, we investigated the effect of two different concentrations (10 or 10...

Optimization of Bacillus subtilis (isolate B246) growth conditions for mass cell production under laboratory conditions was investigated as part of a biological control programme. Aspects such as increasing yield using various starter culture volumes, various media and incubation time and temperatures, were studied. No significant differences between starter culture volumes were found. Potato m...

Isolation of plasmid DNA from Escherichia coli is a daily activity in many molecular biology laboratories. A number of protocols and media recipes have been reported in an effort to make this process more efficient. Here we describe a growth medium that supports much higher E. coli cell densities and, concomitantly, a much higher yield of plasmid than previously reported for small-scale applica...

In a society of knowledge economy, innovation becomes the determinant factor of the development of a country. A mechanism for better knowledge spreading will lead to a successful knowledge economy, within which internet multi-media plays an important role because of its convenience and cost effectiveness of information transference. Therefore, the emergence of internet multi-media determines th...

A green and atom-economical method has been developed for the synthesis of piperazines by cyclocondensation of diols and amines in aqueous media in the presence of a catalytic amount of [Cp*IrCl2]2.

Effect of Nutrient Source Type and Planting Media on Growth Yield Quality Microgreen Broccoli (Brassica oleracea var. italica Planck). The use types nutrient sources planting media is the most important thing in cultivation microgreen broccoli which functions to support growth development so as get good yields. purpose this study was obtain best source growing increasing yield. designed factori...

Somatic embryogenesis is an important biotechnological tool that demonstrates significant benefits when applied to forest tree species; clonal propagation, cryostorage of valuable germoplasm and genetic transformation are among the most promising of its applications. In this chapter, the state of the art of somatic embryogenesis in chestnut (an important economical tree species of the genus Cas...

Abstract The main objective in this article is to study the issue of development and lasting competitiveness and to study its dimensions and also to acquainted with its related components and how to achieve it. In fact, to get acquainted with competitiveness is as a development that would prevent imposition of cultural, Economical, and social and/or environment damages on future generations. ...
