There are two contents of this article. The first is briefly to review the experiment research on catalysis mechanism Carbon Gasification Reaction-CGR(C+CO2=2CO) from 60s -90s. results show that catalytic phenomenon physical rather than chemical, and catalyst does not participate in chemical reaction. activity selectivity related electronegativity or energy level catalyst. second clarify applic...

There is now a large amount of genomic data available in databases for researchers. Computational methods are yet available for data retrieval and analysis, including sequences similarity searches, structural and functionnal predictions. Computationnal detection of genes has received an important interest and many accurate methods are available. However, other functionnal sites are more difficu...

A field experiment was carried out in the year 2014 and 2015 at experimental of Banaras Hindu University, Varanasi, Uttar Pradesh to evaluate effect agronomic weed management practices on crop growth rate (CGR) relative (RGR) direct seeded rice. Twenty-four treatment combinations consisting two mulching viz. no mulch live (brown manuring with Sesbania) nitrogen levels (120 kg ha-1, 150 ha-1&nbs...

given the important role of crop growth indices for explanation of cultivars yield differences in diverse environmental and agronomical circumstances, this experiment was conducted at research field of tarbiat modares university during 2007 growing season. experimental treatments were arranged in split-plot layout based on randomized complete blocks with four replications. in this research, sow...

saving in irrigation water is important in the early season of sugar beet. the effect of early season deficit irrigation on the sugar beet growth indexes was investigated in kabotarabad agricultural research station (esfahan) in 1998. the soil texture was silty clay and the experiment design was randomized complete block with 4 relications. six irrigation regimes were applied after. 1) 100 mm (...

We show that for each integer g ≥ 0 there is a constant cg > 0 such that every graph that embeds in the projective plane with sufficiently large face–width r has crossing number at least cgr 2 in the orientable surface Σg of genus g. As a corollary, we give a polynomial time constant factor approximation algorithm for the crossing number of projective graphs with bounded degree.
