in order to evaluate the comparison of different intercropping patterns of cumin (cuminum cyminum l. ) with lentil (lens culinaris l.) in double crop, a field experiment was conducted based on a randomized complete block design with three replications and eight treatment at the farm located in west azerbaijan province - city nagadeh, iran during growing reason of 2011-2012. treatments included ...

Front row burden is one of the key parameter to improve the bench blasting results. Improper design of the front row burden can create nuisances in the form of ground vibration, flyrock, back break or it may responsible for breakage of improper fragment size from the rockmass. Therefore, front row burden need to be optimised on the basis of proper scientific assessment. It has been proved that ...

Vernonia galamensis Cass is a huge potential industrial crop with very high content of vernolic acid in the seed oil. The experiment was carried out to determine the effect of inter- and intra- row spacing on the yield and yield related traits of Vernonia galamensis Cas.The experiment was conducted for two years during 2014-2015 on experimental field of Wondo Genet Agricultural research center,...

spreading faba bean (vicia faba) cultivation can enhance the sustainability of cropping systems and have other important benefits. however, there is little information on the various aspects of production management for this crop. then, this experiment was carried out to study the response of some agronomic characteristics of faba bean cv barakat to inter- (15, 30, 45 and 60 cm) and intra-row (...

in order to study the effect of row spacing and plant density on quantity and quality yield of soybean in weed competitive condition, a field experiment was carried out at research farm of yasuj agricultural college in summer of 2011. experiment arrangement was split factorial base on randomized complete block design with three replication. the main factor included weed ( in two levels of contr...

The single row routing problem is considered. It is shown that the use of backward moves can reduce street congestion when four or more tracks per street are available. We obtain an O((2k)!k*n*log k) algorithm to determine whether or not n nodes can be wired when only k tracks per street are available. An efficient algorithm is obtained for the case when wires are not permitted to cross streets...

We study preconditioning techniques used in conjunction with the conjugate gradient method for solving multi-length-scale symmetric positive definite linear systems originating from the quantum Monte Carlo simulation of electron interaction of correlated materials. Existing preconditioning techniques are not designed to be adaptive to varying numerical properties of the multi-length-scale syste...

The discovery of unprecedented, non-native phases of transition metal oxides is a fascinating theme in materials chemistry, including the development of new synthetic strategies with excellent sizeand phase-selectivity, and elucidation of their unique physicochemical properties. Most of the first-row transition metal monoxides, such as MnO, FeO, CoO and NiO, are known to exist in a cubic phase,...
