objective: this study is an attempt to examine the anti apoptotic effects of bio on rat msc culture. materials and methods: rat marrow primary cell culture was established and exposure groups were defined; cultures with 0.01, 0.1, 1 μm bio. cells cultured without bio treatment were used as controls. during culture expantion, the average doubling time, as an index of the rate of cell growth, wer...

this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

in order to study the effect of chemical and biological fertilizers on silage corn under different plant densities, a split plot experiment was carried out in a randomized completely block design with three replicates in south western iran. the main plot included nitrogen fertilizer treatment at three levels (n1: with out chemical and organic fertilizers, n2: 75% chemical fertilizer + 100% orga...

The valorization of municipal solid waste (MSW) can serve as an organic amendment in agriculture while reducing accumulation the environment. This research aimed to evaluate a bio-stabilized MSW for production faba bean (Vicia L.) crop. For this purpose, biomass and growth, well as, seed yield components, nutrient accumulation, plant pigments, soil properties, microorganisms were evaluated comp...

As a teenager in a South Dakota hamlet (Pierpont, population 326 in the 1940 census) I had no idea that I would become a scientist. The only formal science course my tiny high school (40 students in four grades, taught by three teachers) offered was physics, taught by the sports coach (a history major) and featuring the ‘‘dissection’’ of a 1928 Overland (teacher: ‘‘I have been told that the mod...

Heavy metal contamination of soils resulting from mining and smelting is causing major concern due to the potential risk involved. This study was designed to investigate the heavy metal (Cu, Zn, Pb and Cd) concentrations in soils and food crops and estimate the potential health risks of metals to humans via consumption of polluted food crops grown at four villages around the Dabaoshan mine, Sou...
