Nitrogen and potassium are the two fertilizer elements that are needed in largest amounts in most tung orchards of the southern United States. Supplying these elements at the optimum rates and in the proper ratios is an important nutritional problem. Leaf analysis has proved to be a valuable criterion .of the nutritional status of tung trees, and, as more basic information on the relation of mi...

One of the challenges faced by the engineering profession is to meet the energy requirement of an increasingly prosperous world. Nuclear power was considered as a reliable option until the Fukushima Daiichi Nuclear Power Plant (NPP) disaster which eroded the public confidence. This short paper shows that offshore wind turbines (due to its shape and form, i.e. heavy rotating mass resting at the ...

The tracing methods determine the contribution the power system sources have in their supplying. The methods can be used to assess the transmission prices, but also to recover the transmission fixed cost. In this paper is presented the influence of the modification of commons structure has on the specific price of transfer. The operator must make use of a few basic principles about allocation. ...

FOREWORD Optimal power flow (OPF) calculations are increasingly critical to modern power systems operationcontrol, markets and planning. However, it is still not easy to obtain reliable OPF solutions that are fully usable in practical power systems engineering. Better methods and software are continually being pursued. This paper discusses some of the calculation and solution requirements from ...

A sustainable microgrid for supplying power to electric vehicles (EVs) is investigated in this thesis. The energy produced by the microgrid would be directly transferred to the electric vehicles via on-road charging systems. The proposed sustainable microgrid is located on the roadside and consists of wind turbines, solar panels and a stationary storage system. The optimum sizing, the topology ...

Abstract Wheat productivity is severely hampered by drought, owing to its negative impacts on crop growth and development. For obtaining better yield, the of drought should be ameliorated. Therefore, current study scrutinizes potential different silicon (Si) forms minify drought-associated reduction in yield changes nutrients accumulation. In a strip plots design based randomized complete block...

We describe a board game in which students assume the roles of supply chain enterprises and move game pieces (e.g. Legos, Velcro, etc.) that represent the parts of a basketball hoop. They then assemble these parts and form the final product and sell it to the customers. The game is the first of its kind to illustrate the concepts of shortage gaming, synchronization of the flow of parts, demand ...
