The study was carried out in the winter (rabi) season to determine effect of Nano and Non-nano nutrient, study's findings revealed that wheat grown with 100% NPK + nano nutrients (N P K Zn) had significantly higher uptake, namely N (143.1 kg ha-1), (28.9 (109.0 Zn (519.5 g ha-1). Applications nutrients—N, P, K, Zn, 75% NPK—worked synergistically increased content uptake over NPK. Similarly, agr...

One of the crucial problems of Lsch a system is locating hundreds of millions of moving portables in an efficient manner. The location registration strategy described in this paper is able to locate active portables automaticalls in the system with ...

The productive efficiency of a firm can be decomposed into two parts, one persistent and one transient. So far, most of the cost efficiency studies estimated frontier models that provide either the transient or the persistent part of productive efficiency. This distinction seems to be appealing also for regulators. During the last decades, public utilities such as water and electricity have wit...
