Deployment of new service assets in operational IT environment is associated with the risk of disruption of the assets of its “basic” condition. Such disruptions cause failures of functioning services. To reduce the risk of disruption, the deploying service assets are divided by releases – sub-sets of service assets that will be embedded in the IT environment in one period. The traditional approach to formation and deployment of releases uses information on services structural properties to predict the number of failures due to the deployment of each service asset, each release and each application for deployment. As a result, the task of managing deployment of service assets is reduced to a sequential solution of three tasks: determining number of releases; determining composition of releases; building a release deployment schedule. The approach is based on the assumption that incorrect deployment of releases is manifested through the failure of services immediately after deployment. In practice, as a rule, this assumption is usually not fulfilled, because the use of various services by users who detect service failures is cyclical (daily, weekly, monthly, quarterly, annual). Many service failures can be detected by users in periods of time that are quite remote from the deployment time of the corresponding IT assets. The article contains the case where the managing process of IT provider configurations of the metallurgical company is well developed, i.e. its configuration database contains information on frequency of various services use at different periods of time. Information on dynamics of services application by users is used to predict time sequence of operating services failures due to deployment of each application. As a result, the task of forming and scheduling deployment of releases is formalized in the form of a discrete nonlinear programming task, the solution procedure of which allows simultaneous determination of number of releases, their composition and schedule for their deployment.

The objective: to show a role of the family focused technologies in depression of frequency of pathology of pregnancy at women of high obstetric risk. Patients and methods. For determination of efficiency of prophylaxis of pathology of pregnancy on the basis of use of the family focused technologies complex clinical-psychological and laboratory and tool examination of 300 women with factors of obstetric risk which were divided into two groups was conducted. In the main group – 182 women with motivation on partner labors to which provided training on system of individual preparation of married couple to labors. The comparison group consisted of 118 women who were not in prenatal training and had individual support in childbirth, with the traditional approach to pain management. Results. Use of the family focused technologies during pregnancy allows to reduce significantly the frequency of the main complications of pregnancy, especially not incubation and premature births. Conclusion. In our opinion, the technique is simple, available and can widely be used in practical health care at women with high obstetric risk. Key words: obstetric risk, the family focused technologies, prophylaxis.

The present study compares the progressive collapse approach with the traditional temperature screening method on determination of PFP requirements at topside offshore structures. The advantage to evaluate the consequences of fire scenarios on the global integrity and stability of topside modules can be revealed by a substantial reduction of the required amount of PFP, and consequently significant cost savings for operators, when compared to the traditional approach. In the case study presented in this paper, there is a reduction of 79% in PFP allocation.

The objective: to show a role of the family focused technologies in correction of psychological status and depression of frequency of pathology of pregnancy at women of high obstetric risk. Patients and methods: for determination of efficiency of prophylaxis of pathology of pregnancy on the basis of use of the family focused technologies complex clinical-psychological and laboratory and tool examination of 300 women with factors of obstetric risk which were divided into two groups was conducted. In the main group – 182 women with motivation on partner labors to which provided training on system of individual preparation of married couple to labors. The control group consisted of 118 women with a traditional approach to pain management that have not been prenatal training. Results. Use of the family focused technologies during pregnancy allows correction of psyhological status and to reduce significantly the frequency of the main complications of pregnancy, especially not incubation and premature births. Conclusion. In our opinion, the technique is simple, available and can widely be used in practical health care at women with high obstetric risk.

In any real-world manufacturing situation, the problem of determining the optimum machining conditions involves not only empirical data but also imprecise information. Uncertain factors may need to be considered in the computational optimization process due to fuzziness present in the empirical equations and experimental data used. To manipulate the uncertainties in the optimization process, a fuzzy model is introduced and investigated. The fuzzy model quantifies the degree of certainty (or uncertainty) in the range 0 to 1. A numerical example is considered to illustrate the computational approach. The overall impact of the uncertain factors on the optimization process is assessed by comparing the present numerical results with those given by the traditional approach.

Currently, high performance concrete (HPC) is becoming more and more popular mainly because of its great mechanical parameters. As in the case of ordinary power concrete (OPC) it is necessary to improve the load bearing capacity with using of reinforcement. The present age calls for using of very thin structures for reasons of both environmental parameters and visual quality. Based on this fact, reinforcement start to use durable composite materials, such as technical textiles made of them. Element of HPC with this type of reinforcement is called textile reinforced high performance concrete (TRHPC). It is impossible to use the traditional approach for usually used steel reinforcement if we want to design these extra-thin structures. Modeled structures are very sensitive for input parameters and the development of standards for TRC material lags. The present study is focused on the different method of approach for the determination of tensile modulus of composite reinforcement. Three used methods are compared with each other using numerical analysis of four point bending test of façade element for one type of used reinforcement. Curves from numerical analysis are finally compared with the curve from real experiment and based on this the final evaluation is generated.

Adams's catalyst PtO2 x H2O has an important application in the chemical industry. The method for determination of platinum in Adam's catalyst has been elaborated. It includes the combination of cupellation and gravimetry methods. Considering that platinum oxide is practically insolvent in mineral acids, the sample is alloyed with lead by cupellation method and the separated balls solution procedure has been tested. The ball, platinum and lead alloy, is soluble in mineral acid. The platinum was settled by amonium chloride from solution, and obtained deposit treated by amonium acetate with addition of ethanol for lead removing. The retained platinum was determined by atomic absorption spctrophotometry method in the filtrate (after the platinum separation) and the final result of platinum content corrected. It was shown how the combined gravimetric and AAS-Pt determination methods might be used for solving determination of Pt content in practically unsoluble sample of catalyst. Applied procedure enables testing the catalyst quality and proving its characteristics required for chemical industry.
