Quantification of the Nitrogen (N)-supplying capacity of organic manures provides an important insight into more effective N management practices. The aims of this study were to determine the potential N mineralization of cow manure (CM), poultry manure (PM), urea fertilizer (UF) and the combined use of cow manure + urea fertilizer (CM + UF) for silage maize (Zea mays L.) in a calcareous so...
On the importance of thermal resistances of the cooling system when choosing a thermoelectric module
Calculations and analysis of the energy characteristics cooling thermal control system are carried out, taking into account operating thermoelectric module, resistances heat supply removal devices, parameters cooled object. The efficiency is compared when using two serial modules with different power. It shown that a significant factor affecting resistance devices for supplying removing heat. C...
increasing overall liberalization and improving reliability indexes are the two prime but often conflicting objectives of electricity markets. proper embedding of regulatory intervention of price caps provides an effective means to tradeoff between these two objectives. surprisingly, in the context of the infinitely repeated game paradigm, as in the case of actual electricity markets, the domin...
Nitrogen has an important role for supplying carbon skeletons which needs for producing compatible solutes and stress tolerance enzymes. Water deficit affects nitrogen fixation in legums. So we studied the effect of various nitrogen sources on physiological, and biochemical features of bean under water stress. This experiment was conducted as factorial based on completely randomized design with...
