An experiment was conducted to investigate the environment of the deep litter system and provided theoretical basis for production.
A main task in agriculture production is field management of water and fertilizer. Excessive fertilizer and water application not only waste resource but also pollute the environment. The traditiona...
The paper describes the system for measuring and logging of data on soil water content and soil temperature profile. The system was tested in a field and shows great potential for performing continuou...
One of the most controversial issues in recent years in water management has been finding a balance between available resources and water needs related to certain territories. The changes brought abou...
In this paper a spatially distributed hydrologic model (WetSpa) is used to estimate daily river water discharge in Gorganrood river basin, Iran. The model combines topography, land use and soil maps, ...
Superheated steam (SHS) was applied to food processing because of advantages including efficient heat transfer by latent heat, and prevention of product oxidation. SHS heating solves problems such as ...
Kanvinde and Sastry (Appl. and Environ. Microbiol. 56:2087-2092, 1990) had previously demonstrated that A. tumefaciens has all the physiological characters of a diazotroph. Genetic evidence indicates...
The power quality (PQ) requirement is one of the most important issues for power companies and their customers. Continuously monitoring the PQ from remote and distributed centers will help to improve ...
This article introduces a novel three-dimensional continuous autonomous chaotic system with six terms and two quadratic nonlinearities. The new system contains two variational parameters and exhibits ...
Voltage sags in the electric power system are mostly due to faults in the power system. Voltage sag is characterized by its magnitude (the retained voltage), phase-angle jump, unbalance in the sag in ...
A study pertaining to seasonal variation in physicochemical properties was carried out at five sites of Tapi estuarine zone for a period of one year i.e. July 2008 to June 2009. It revealed that the ...
We present a multi-species model of one plant with two nectivore pollinators. This system has mutualism between the plant and the pollinators, and competition for food between pollinators. Both polli...
Floodplain management is a recently new and applied method at the river engineering and is essential for prediction of flood hazards. On the other hand, for the purpose of managing and performing all ...
A study was conducted in the Department of Agricultural Extension, University of Agriculture, Faisalabad, Pakistan during 2007. A sample of 408 farmers was selected randomly through multistage sampl...
为了真实地模拟植物生长发育过程,引入了Open L-System建模理论。在植物形态发生模型的基础上,根据植物生长时其形态特征及环境之间的相互作用,构建了综合考虑植物生长发育与环境影响的虚拟植物模型。
