This research has been performed within the project “prediction, measurement, and analysis of composite electromagnetic field of artificial radiation sources,” funded by the Ministry of Science and Technology of the Republic of Srpska, Bosnia and Herzegovina. The ultimate goal of the project is the installation of a monitoring network for continuous measurement and recording of nonionizing electromagnetic (EM) radiation levels in the wider area of Banja Luka city centre covering about 10 km2. For this reason it was necessary to make an optimal choice from a dozen of measurement points with the maximum value levels of total EM field. It was a difficult task, because in this case, with the resolution of 5m × 5m, approximately 400,000 points should be examined. Therefore, the pedestrian zones, areas, and routes with significantly smaller surfaces but with the largest flow of people have been examined, so the time required for their mapping with values of total EM field has been reduced to a more realistic framework. In this paper, in the volume allowed by the defined criteria, a fast and reliable experimental method has been described, which has been examined at one of the studied areas in the named project, with surface of 0.008 km2.

SummaryLaser nephelometry is a technique which allows the evaluation of the concentration of several serum proteins and clotting factors. By means of this technique it is also possible to study the kinetics of the reaction between antigen and antibody. We studied the kinetics of the reaction between prothrombin and an antiprothrombin antiserum using several prothrombins namely: Prothrombin Padua, prothrombin Molise, which are two congenital dysprothrombinemias, cirrhotic, coumarin or normal prothrombins. Different behaviors in the kinetics of the reactions were shown even when the concentration of prothrombins was about the same in all plasma tested. These differences were analyzed by means of a computer (Apple II 48 RAM) programmed to solve four unknown equations (Rodbard’s equation). From the data so obtained one can see that when voltages at the beginning and at the end of the reaction are in all cases about the same, a clear difference in the time required to reach half the maximum value of the voltage can still be demonstrated. This parameter, which is expressed in minutes, is longer in coumarin and prothrombin Molise than in controls. On the contrary it is shorter in prothrombin Padua and has about the same value of controls in the cirrhotic patient. Moreover the time at which the maximum rate is obtained is longer in coumarin and prothrombin Molise than in controls and shorter in liver cirrhosis and prothrombin Padua. In conclusion data obtained show that coumarin prothrombin behaves in a different way from cirrhotic prothrombin and also that there is a different behaviour between the two congenital dysprothrombinemias.

The influence of mineral fertilizers on morphometric parameters of Melissa officinalis (Melissa officinalis L.) was studied. It is shown that the morphometric indicators changed depending on the meteorological conditions and the types of mineral fertilizers. The most active shoot formation was observed on the variant with the use of phosphorus-potassium fertilizers. The maximum value of the leaf surface index (leaf area index – LAI) of Melissa officinalis plants was recorded in 2017 on the variant with the use of nitrogen-potassium mineral fertilizers.

One of the most used renewable energy sources worldwide is geothermal energy. Itrepresents the heat, originated by natural processes happen in the Earth interior. The hot springsphenomena are the most frequent natural manifestation of geothermal activity.Geothermal potentiality of some area can be estimated based on geothermal gradient. Geothermalgradient is a conductive terrestrial parameter that represents the degree of increasing of the Earthtemperature vs. depth. It is usually expressed in ⁰C/m or ⁰C/km. Different areas have differentthermal gradients and thus different geothermal potential. Generally, higher geothermal gradientscorrespond to areas containing more geothermal energy.Geothermal characteristics of the territory of the Republic of Srpska are closely related to itscomplex geological setting. It is the reason why geothermal characteristics are different from areato area. Higher geothermal potentiality is recognised in the northern parts of the entity, in the firstorder in Semberija, Posavina and Banja Luka regions.The use of geothermal energy with different fluid temperatures can be considered throughthe Lindaldiagram, who firstly proposed acomprehensive scale with appropriate temperatures for differentuses. High temperature fluids are mostly used for electricity production and moderate and lowtemperature fluids for the direct use.Despite the fact that the territory of the Republic of Srpska hasfavourable geothermal properties, utilization of this kind of renewable energy resource isinadequate. Especially indicative are data about the use of geothermal energy by heat pumps (inbad sense) in comparison with praxis of developed countries.Chemical composition of thermal waters plays very important role and can be used in itsexploration stage, for analyses of possibility of its use and for prediction of exploitation effects, aswell. This kind of renewable energyresource, highly ecologically recommended, must be consideredmore seriously in the future in the Republic of Srpska. Furthermore, it must be put into the energystrategic documentsin appropriate manner.

The key task of the tool manufacturing is to create or to choose such a type of tool, which would permit to provide high processing efficiency, the best tool`s workability and the quality of the machined surfaces with minimum expenses and resources. The optimal choice of the constructive tool modifications from a variety of options takes much time required for the preparation of the tool to work. To solve this problem, we have developed software that allows you to create, organize and carry out a comparative analysis of structural instruments in order to identify rational option for the given conditions of production. Ordering and selection of a rational design of the instrument is carried out in accordance with established procedures of modeling and comparative analysis of design solutions. Application software can reduce design time technological process by 80...90%, and get a substantial annual economic effect.

Forecasting System

<p>Probabilistic forecasts are essential for good decision making, because they communicate the forecaster's best attempt at representation of both information available and the remaining uncertainty of a variable of interest. The amount of information provided, which can be measured in bits using information theory, would then be a natural measure of success for the forecast in a verification exercise. On the other hand, it may seem rational to tune the forecasting system to provide maximum value to users. Somewhat counter-intuitively, there are arguments against tuning for maximum value. When the design of the forecasting system also includes the choice of the sources of information, monitoring network optimization becomes part of the problem to solve.  <br>In this presentation, we give a brief overview of the different roles information theory can have in these different aspects of probabilistic forecasting. These roles range from analysis of predictability, model selection, forecast verification, monitoring network design, and data assimilation by ensemble weighting. Using the same theoretical framework for all these aspects has the advantage that some connections can be made that may eventually lead to a more unified perspective on forecasting. </p>

We calculate the one-loop free energy for two parallel D-branes connected by open bosonic (neutral or charged) string in a constant uniform electromagnetic (EM) field at nonzero temperature. For neutral string, external EM field contribution appears as multiplier (Born-Infeld type action) of one-loop quantities without the external EM field. The Hagedorn temperature is not changed if compare with the case of standard string gas in the constant electromagnetic field.

In this paper we consider a four-level W-type atom interacting with a single-mode quantized electromagnetic field in the presence of the Kerr medium. The atom and the field are initially prepared in the excited state and coherent state, respectively. The influence of the Kerr medium on the N-order squeezing and Poissonian statistics is investigated. We found that the maximum value of squeezing decreases by increasing the order N. Also, we noticed that the Kerr-like medium decreases the amount of squeezing and increases the sub-Poissonian statistics.

Introduction. Since 1897, when the first radical hysterectomy with lymphadenectomy was done by Wertheim in Vienna, this operation has had the central role in the surgical treatment of invasive cervical tumors. Material and methods. In the period from 1997 to 2010, 177 patients diagnosed with invasive cervical cancer according to the International Federation of Gynecology and Obstetrics (FIGO) stage IB1 - II were operated at the Department of Obstetrics and Gynecology in Banja Luka. All patients underwent radical hysterectomy by Wertheim - Meigs. The aim of this study is to present the technique of this operation, as well as its effectiveness in the treatment of cervical cancer. Results. The distribution of the patients having invasive cervical cancer according to the International Federation of Gynecology and Obstetrics classification was as follows: I B1 - 35.67%, I B2 - 23.17%, II A - 15.48%, II B - 25.68% on average is 21.3 removed lymph glands. The rate of intraoperative and postoperative complications was 8 (4.51%) and 17 (9.60%), respectively. Of the 26 patients who were operated in the period from 2005 - 2010, 13 had stage II B according to the International Federation of Gynecology and Obstetrics; there were 6 lethal outcomes (23.08) and the five-year survival rate was 76.92%. Discussion and conclusion. By applying the proper surgical technique and early prevention of immediate complications, we achieved satisfactory results in operative morbity and mortality, intraoperative and postoperative complications of the lesion for radical surgery by the Wertheim- Meigs-in the treatment of cancer of the uterus in the I B - II B stage according to the International Federation of Gynecology and Obstetrics classification.
