soil compaction is one of the most prevailed limitations for crop growth. the use of organic matters as fertilizer on agricultural soils can reduce the effects of soil compaction and provide the nutrients for the plants. so, a factorial experiment was carried out in a randomized complete blocks design with three replications. the first factor was the source and amount of organic fertilizer (far...

objective: infection with herpes simplex virus type 1 induces viral latency in neuron trigeminal ganglions. the late associated transcript (lat) is uniquely expressed in infected neural cells, however no coding protein associated with these transcripts has been identified in infected cells. it has been shown that six micrornas transcribed from lat have the capabilities to affect the cell signal...

3-(2-furanyl)-2-propenoic acid has been used to prepare a new series of organotin complexes of general formula r3snl (r=me, et, n-bu, ph and cy) and r2snl2 (r=me and n-bu). these complexes have been characterized by elemental analyses, ir, 1h-nmr, mass and mössbaure spectroscopy.

bisphenol-a (bpa) is an industrial xenoestrogen used widely in our living environment. recently, several studies suggested that bpa has destructive effects on dna and chromosomes in normal body cells via estrogen receptors (er). therefore, bpa could be considered as an important mediator in many diseases such as cancer. however, there are still many controversial issues which need clarification...

in the present work, b-zsm-5 zeolite membranes were synthesized on porous tubular α-alumina supports by several subsequence in situ crystallization hydrothermal treatments. the tio2- bohmite and ɣ- alumina intermediate layers were applied to improve the lattice matching between zeolite layer and the support. the uniform membrane intermediate layers with low permeation resistance were prepared o...

the new device made in this study could calculate the proper position of tillage tools relative to the land surface at each point, and hydraulic operator set its optimum position. the optimum position of tools is calculated by depth control software developed for this device, and its input data were depth for root development. the performance of device was tested on subsoiler for precision till...
