This chapter presents a genetic algorithm to obtain the position and orientation of each multiple-input multiple-output array antenna that maximizes the ergodic capacity for a given propagation scenario. The simulations of the genetic algor

Micronutrients and Crop Production: An Introduction,nd zinc (Zn). Whenever the supply of one or more of these elements is inadequate, yields will be reduced and the quality of crop products impaired, but crop species and cultivars vary considerably in their susceptibility to deficiencies. Zinc deficiency is the most ubiquitous micronutrient problem t

Micronutrient Deficiencies in Australian Field Crops,and Zn are most widespread, being common on acid and alkaline soils respectively. Zinc deficiency is notable for being the most widely distributed micronutrient problem globally as well as in Australia, occurring on all soil classes, acid and alkaline, sandy and clayey, humid and arid, and in hot an

Micronutrient Deficiencies in Crops and Soils in India,ty of various sources of the elements, and techniques for their application. Crops grown in most soils in India suffer from deficiencies of one or more micronutrients, even though the soils often contain apparently adequate total amounts of the respective elements. The nature and extent of deficienc
