Large changes occur in the ascorbate system during the development of Vicia faba seed and these appear closely related to what are generally considered to be the three stages of embryogenesis. During the first stage, characterized by embryonic cells with high mitotic activity, the ascorbic acid/dehydroascorbic acid ratio is about 7, whereas in the following stage, characterized by rapid cell el...

in order to assess the performance of two soybean cultivars produced in two regions including karaj and moghan to drought stress at reproductive stages and also the impact of drought stress on yield and its components, oil and protein percent, an experiment was conducted as a split factorial based on complete randomized block design in three replications in agriculture faculty of tarbiat modare...

evaluating of some physiological indices for recognizing water deficit effects, selecting water deficit tolerant oilseed rape genotypes and also evaluation of drought effects on seed and oil yields and its components were the goals of this study. the experiment was conducted as factorial based on a randomized complete blocks design with three replications in east azarbaijan research center for ...

B. BACKGROUND: With the time rapidly approaching when we will need to grow food plants in an orbiting space station, in a lunar base, and in a station on Mars, it would be important to know just how much fertilizer is absolutely necessary for maximum growth in those environments. Payload size for launching support materials is very precious, so we don't want to send up any more than necessary. ...

This paper describes the design of a very high speed optoelectronic analog digital converter based on a digital division algorithm called SRT division using n–i(MQW)–n Self Electro-Optic Effect Device (SEED) technology. The proposed structure is a pipeline ADC. The SRT algorithm was chosen because it provides a redundancy at each stage of the pipeline. The amount of redundancy is dependent on t...

It is especially difficult for seed stage companies to find adequate financing. In the last decade venture capital (VC) has played significant role in funding seed and start-up stage companies. Our study focuses on the financing of seed stage companies via venture capital funds subsidized by the state and European Union. Seed stage companies are supported by incubator houses with infrastructure...
