introduction nowadays, salinity is one of the limiting factors for crop production in arid and semi-arid regions. on the other hand, sorghum (sorghum bicolor l.) is a self-pollinated and short-day plant, which partly has been adapted to salinity and water stress conditions; also play an important role in humans, livestock and poultry nourishments. all studies have showed the positive effects of...

silicon has useful effects on growth and yield of many plants. the aim of the present study is to investigate the impact of nano silicon oxide on proliferation and improvement of some growth traits of apple, cultivar gala. thus, an experiment was designed based on completely randomized design (crd) with five levels of nano silicon oxide concentrations (0, 25, 50, 100 & 200 ppm) in five replicat...

A new Group Contribution Method based on elements and chemical bonds was proposed to predict the enthalpy of evaporation organic compounds at their normal boiling points. prediction model built using 1266 experimental data points, accuracy estimations evaluated 16 The method has only 42 groups, a simple way group splitting, wide range predictions with an average relative error 5.84%. Furthermor...

Abstract: In the current work, the strain hardening behavior of dual-phase steels with different silicon content (0.34- 2.26 Wt. %) was examined using the modified Crussard-Jaoul analysis. It was shown that these dual-phase steels deform in two stages over a uniform strain range. Each stage exhibited a different strain hardening exponent varying with silicon content. At the first stage, work...

This art ic le descr ibes the use of sul fur-containing organic monolayers to improve the adhesion of gold to sil icon substrates having a native sil icon dioxide surface layer. Gold adheres to clean sil icon,r but not to sil icon dioxide.2 The affinity of gold toward sil icon dioxide can be improved by coating with chromium3 or titaniumt films or by adding interlayers containing fluoride salts...

The main aim of this study was to evaluate the effects of silicon (Si), ethanol (Et), ascorbic acid (AA) and citric acid (CA) on vase life of Narcissus tazetta L. cv. ‘Shahla’cut flowers. For this purpose, an experiment based on completely randomized design was conducted with Si (5, 10 and 20 mM), Et (2 and 4%), AA (100, 200 and 300 mg L-1), CA (100, 200 and 300 mg L-1) and control (distillated...

Novel silylium ions with N-heterocyclic imines were successfully synthesized. The reaction of trimethylsilyl imidazolin-2-imine Me₃SiNIPr (NIPr = bis(2,6-diisopropylphenyl)-imidazolin-2-imino) with B(C₆F₅)₃ leads to dimeric imino-substituted silylium ions through a methyl group abstraction on the silicon atom. Meanwhile, the intermolecular imino-coordinated silylium ion is formed by using the l...
