The effect of fertilizer rate on the growth, development and yield of sweet pepper in protected areas

The article presents information on the development of the root system when the Marjona variety and the Zombello F1 hybrid of sweet pepper are grown in the conditions of greenhouses in the meadow gray soils of Samarkand region, Samarkand district, with different fertilizer rates. Key words: Grassy gray soil, protected land, sweet pepper variety Marjona, Zombello F1 hybrid, fertilizer rates and yield

A numerical solution for plain problems of theory of elasticity

In this paper ,a generation of a numerical algorithm for solving theory of elasticity plain problem concerning displacements is desired ; using difference equations that the method of successive approximations proceed through transforming a complex (to be solved) differential equation into an algebraic one that’s much more easier to solve. The algebraic equations resulted adopt both positioned nodes; interior nodes of a computational grid, and contour (boundary) nodes; including corner ones. The evaluation of the new generated algorithm is being validated through applying it on solving a problem of a laterally fixed deep-beam. Obtained numerical results out of the new algorithm to be compared with those early known and stated in the references listed at the last part of the article

Gold Leaching by Various Solutions, Alternative of Cyanide and Their Prospects in the Future

В статье рассматриваются четыре альтернативных заменителя цианида для извлечения золота из руд и концентратов. Цианид был лучшим реагентом для выщелачивания золота, на протяжении более 100 лет, из-за его высокого извлечения, низкой стоимости и надежности. Однако ущерб, наносимый им окружающей среде в результате неправильного управления, привел к повсеместным исследованиям, направленным на выявление и разработку менее токсичных выщелачивающих реагентов. В статье рассматриваются наиболее широко исследованные заменители цианида, но очевидно, что ни один из них еще не внес значительных результатов в доминирующее положение цианида, как предпочтительного реагента на подавляющем большинстве золотых приисков по всему мируThe article discusses four alternative cyanide substitutes for the recovery of gold from ores and concentrates. Cyanide has been the premier gold leach reagent for over 100 years due to its high recovery, low cost and reliability. However, environmental damage from improper management has led to widespread research aimed at identifying and developing less toxic leaching agents. The article discusses the most widely researched cyanide substitutes, but it is clear that none of them has yet made any significant incursion into the dominance of cyanide as the preferred reagent in the vast majority of gold mines around the worl
