Investigation results of dairy proteins
coprecipitation from skim milk and curd cheese whey are demonstrated. For different ratio of the components in the milk-whey mixture, the authors determined the parameters providing maximal effi-ciency of precipitation and outlined the factors stipu-lating intensity of separation and properties of pro-tein-chitosan complex. Efficiency of whey protein isolation and interaction of chitosan with protein in stable complex are explored
In the article, the results of the theoretical researches, allowed to prove rational values of key parameters of drainage systems in the conditions of mountain agriculture of the Kabardino-Balkarian Republic are resulted
The article is devoted to the researching of complete observability of time-varying perturbed differential-algebraic system. The method of cascade splitting of the original space to the subspace is used. The formula for finding the state vector is derived. The relations between input and output functions are obtained
In the article we have represented the following items: the sphere of utilization of the ozone in apiculture, the mathematical model which establishes connection between level of development of bee families and parameters of in-hive microclimate and allows to theoretically substantiate the spring development up to 35 % as a result of ozone treatment; the results of experimental investigations of the influence of ozone treatment parameters on the spring increasing of bee families; feasibility study of ozone generators' application in apiculture; recommendation for application of the results of investigation are given
In the article we have represented the following items: heating model of discharge device of the ozone gen-erator which allows to examine the transient process and establishes dependence of heating time constant of the dielectric barriers on constructive parameters of discharge device. The rational parameters of design of the ozone generator for in-hive treatment of the bee families are defined; recommendations for utilization of the results of investigations are given
Identification of the processes of knowledge manage-ment technical service companies was done. A general model of field subject was presented in the form of ontology. Software ontological modeling was re-viewed
Results of rheological investigations of
protein-chitosan complex obtained from milk-whey system with different ratio of components are demon-strated. Portable consistometer to determine elastic behavior of the samples is designed.
Optimal protein-chitosan complex, close in
rheological parameters to curd cheese 18% fat, is detected
In this article, contact conditions are investigated at superficial plastic deformation by running-in rollers of details by a method of load cells
The article describes the results of experimental researches of receiving fullerene soot in plasma of impulsing discharge. Receiving the soot of fullerene occurred at fuel oil decomposition. From features of experimental conditions, it is possible to specify that synthesis of fullerene nanocarbon soot occurred at atmospheric pressure. The analysis of the received samples of a fullerene soot was made by a mass spectrometry method with a laser desorption (MALDI). For the purpose of increase of efficiency of plasma chemical synthesis the cathode is executed in the form of a hollow can with a permeable bottom wall through which giving of a hydrocarbon material was made
The possibility of reducing dynamic loads on the driving elements of hydraulic manipulator with a combination of motions of the three links is theoretically justified and confirmed by tests
