Description
One-temperature limited version of the general model of adsorption-contact drying for the ceramic brick is considered. Numerical modeling of heat and mass transfer in the donor and the acceptor samples for one-dimensional approach is carried out. It is shown, in particular, that the moisture diffusion coefficient of material in the contact zone can vary significantly due to changes in the conditions for liquid-phase transfer

MODELS AND METHODS OF CONTROL SYSTEMS OF ECOLOGICAL SAFETY OF FOUNDRY MANUFACTURE
Description
The given developments are devoted to modeling of control systems by ecological safety of foundry manufacture. In a working zone of foundry shops except for a dust the significant amount of polluting substances is allocated. The most unsuccessful sites from a position of allocation of a dust are chambers and lattices. The experimental analysis shows, that in structure of a dust the weight maintenance of fractions with a diameter up to 20 microns reaches 43,8 % on weight. The given dust is most dangerous to health of the working personnel and creates problems when clearing the air

Description
The model of identification of process of a dust con-tent of the air is submitted. It is shown, that in a work-ing zone of foundry shops the significant amount of a dust is allocated. The most unsuccessful sites from a position of allocation of a dust are chambers and lattices. The experimental analysis shows, that in structure of a dust the weight maintenance of fractions with a diameter up to 20 microns reaches 43,8 % on weight. The dust is most dangerous to health of the working personnel and creates problems at clearing air. The model of structure of dusty air is received

FORMATION AND CONTROL OF TRIHALO-METHANES IN THE DRINKING WATER OF BAGHDAD
Description
The article is devoted to the formation and transfor-mation of trihalomethanes (THMs) in water supply system of Baghdad (Iraq). The results of research work show the dependences of THMs concentration in the tap water on the distance from water treatment plants, chlorine residual and water temperature. It is shown that the way to reduce THMs in Baghdad water supply network is to use the chlorine dioxide for chlorination as well as sorption treatment in case of preliminary chlorination

BUILDING AN EMPIRICAL DEPENDENCE OF THE GRANULOMETRIC COMPOSITION OF FOUNDRY DUST
Description
The article considers the model of granulometric composition of foundry dust. We used the method of particle size analysis, which is based on the dependence between the size and the velocity of a body under the action of gravitational or centrifugal forces. Determination of granulometric composition of the given sample of powder was made using the laser diffraction method, implemented on a laser particle analyzer, Fritsch NanoTec “ANALISETTE 22”. A model of dust particle size distribution has been obtained

PREDICTION IN MANAGING OF POTENTIALLY DANGEROUS OBJECTS
Description
In this article, the method of normalized amplitude for predicting changes in key technological parameters of potentially dangerous object, which can lead to abnormal situations is used. The article provides guidelines for choosing the step between the values of the original time series and its length

SEMANTIC DOMINANTS OF CONSTRUCTIONS WITH THE VERB TENER IN K.J.SELA AUTHOR STILE
10.00.00 Philological sciences
Description
The article deals with the concepts of situations that are set by the verb ‘tener’ on a material of Kamilo José Sela work of art. Semantic dominants of constructions with ‘tener’ are defined and analyzed
-
Description
The article deals with questions of organizational forms of additional training of future engineers that is based on synergetic approach. The motivation issues to training as a result of social consequences of reforming of engineering education are considered. The interaction of subjects of educational space and specific questions of training and education based on self-organization of students are analyzed

FORMATION MODEL OF INVENTORY REPAIR MANAGEMENT FOR LOGGING ROADS
Description
The article presents the mathematical model and algorithm searching for the optimum amount in rates of repair materials. These solutions account for the dependence of the transport costs of repair on the volume parties. They include a wide range of changes in the cost per unit volume of material. Solutions provide an effective inventory management in maintenance and repair of logging roads
