OF2 and VAP genes, probably involved in signal transduction of sugarbeet nematode resistance, have already been cloned in bacterial vector by AFLP molecular marker and a two-hybrid system, respectively. To examine their capability to introduce resistance in sugarbeet, the genes were transferred to plant expression vectors. For this reason, OF2 gene after isolation was inserted within T-DNA of p...
مقدار تبخیر و تعرق حقیقی مزرعه یونجه واقع در باجگاه بوسیله روش تعادل آبیاری در 9 کرت آزمایشی و دولیسمتر از نوع وزنی بمنظور تعیین آب مصرفی گیاه یونجه تعیین شد. در طول مدت آزمایش مقدار آب موجود در خاک بوسیله نمونه برداری وزنی از خاک و دستگاه نوترون متر تعیین و مقدار تشعشع رسیده از خورشید بزمین و ساعات آفتابی روز نیز اندازه گیری شد. مقدار تبخیر و تعرق پتانسیل بوسیله روشهای modified blaney-criddle ...
Abstract In this paper we introduce constitutive artificial neural networks (CANNs), a novel machine learning architecture for data-driven modeling of the mechanical behavior materials. CANNs are able to incorporate by their very design information from three different sources, namely stress-strain data, theoretical knowledge materials theory, and diverse additional (e.g., about microstructure ...
In this first of two articles on the modeling of tablet compaction, the experimental inputs related to the constitutive model of the powder and the powder/tooling friction are determined. The continuum-based analysis of tableting makes use of an elasto-plastic model, which incorporates the elements of yield, plastic flow potential, and hardening, to describe the mechanical behavior of microcrys...
Ahstraet-A stress resultant constitutive law in rate form is constructed for power-law hardening materials. The change of plate thickness is considered in the constitutive law. The elastic-plastic behavior of a plate element based on the stress resultant constitutive law under uniaxial combined tension and bending is determined under a limited number of nonproportional and unloading paths. The ...
