Flocculation of Natural Turbid Water by Amide-, Carboxyl- or Amine-Containing Polyelectrolytes
Реферат: The flocculation of natural turbid water with various concentrations of suspended solids in the presence of high-molecular polyelectrolyte flocculants different in location, density, quantity and charge of functional group in the macromolecule chain as well as in the presence of aluminum sulfate coagulant was studied. The interaction processes between flocculants and suspended solids in natural turbid water were shown to be identical but different from its interaction with low-molecular aluminum sulfate coagu┐lant.

Реферат: This study presents a fuzzy logic-based control system for controlling the protected cultivation and describes its advantages over the traditional greenhouse automation control systems. We present a design of fuzzy logic-based controller, which optimizes the greenhouse energy and water consumption. The design includes the main linguistic variables for sensor and actuator subsystems. Membership functions of Fuzzy Inference System (FIS) are generated and simulation and analysis of the behaviour of the designed control system is performed. The result shows that the designed control system beside its relative simplicity is flexible and adaptive, taking into account the differences in crop varieties and growth stages. Preliminary simulation of energy savings compared with the costs on actual field shows also good results. Still, number of different control strategies has to be applied in order to increase system flexibility regarding the different varieties.
Structure Formation of Soil in the Presence of Copolymerization Products of Maleic Acid and Acryl Amide with Nitrogen Base
Реферат: Structure formation activity of carboxylic, amide group containing water soluble polymers (WSP), obtained under different conditions, have been studied. The dependence of structure formation properties of WSP upon conformation of macromolecules, that altered with the quantity of organic base, coordinated to carboxylic functional groups as a neutral molecule in free state, has been discussed.

Реферат: Two field experiments were carried out to study the effect of cobalt on soybean growth and productivity. Experiments were conducted at Research and production Station, National Research Centre, El-Nobaria, Beheara Governorate, Delta Egypt under drip irrigation system during two the successive seasons of 2010 and 2011. Cobalt added once i.e. 0, 4, 8, 12, 16 and 20 ppm. All required agricultural managements for plants growth and production were carried out as recommended by Ministry of Agriculture.

Реферат: Features of climatic conditions of the southern region of Kazakhstan strongly influences formation of superficial water resources and all microclimate of the region. It is necessary to make for reduction of complex monitoring and the analysis short and long-term forecasting on the basis of GIS DB. In this regard productivity indicators were received on: potential productivity, climatic security of productivity, really possible productivity and productivity in production.
