In presented contribution two types of glass-metal bond are investigated by scanning electron microscope (SEM) equipped with EDS. Firstly, a mechanical bond, which usually provides weaker random joints. Secondly, chemical interaction, where the oxide layer on the metal surface forms a strong bond with the glass. Additionally magneto-impedance measurements are used to determine surface magnetic properties of microwires with and without glass cover. Considering giant magneto−impedance (GMI) effect, which is mainly a surface effect at higher frequencies, is very sensitive to the rotation of magnetization in the shell of a microwire. Thus GMI measurements are often used to determine magnetic anisotropy, hysteresis and residual magnetic domain structure formed around local defects (pits) on the surface of amorphous ferromagnetic microwires.

Linear Accelerators and Cobalt units are common source of radiation for external radiotherapy. In Vivo Dosimetry (IVD) is a real time quality control set of methods used in cancer treatment clinics to assure that dose is delivered as prescribed to tumor, while surrounding healthy tissue is spared. Silicon Diode detectors are among most popular detectors used for IVD. In certain clinical conditions, both entrance and exit dose measurements are needed, for quality insurance, to calculate the dose received by tissue or organ inside patient’s body. Response of silicon diode detectors depends on multiple factors therefore prior of use in IVD each detector needs to be calibrated and corresponding factors of correction need to be calculated. Correction factors are needed to calculate dose for different field sizes, angle between beam axis and couch axis, skin to source distance (SSD), temperature etc. In this work we present our calculation of exit dose calibration factors for six silicon diode detectors made by PTW Frieburg Germany. Diodes are calibrated for exit dose under either 6 MVor 18 MV beam of photons as designated by manufacturer. Further we study dependence of response of individual diodes on distance from source and calculate corresponding correction factors. It was found that exit dose SSD dependence is pronounced and correction factors are necessary for exit dose IVD with diode detector in clinics.
Features of use of the distributed heterogeneous systems for carrying out numerical experiments are considered. The method of the organization of small diverse experiments within one umbrella project of the voluntary distributed computing on the BOINC platform is offered. Benefits of carrying out small numerical experiments are given in the umbrella project.
Two different laundering procedures were executed in the research. The first investigated procedure was a classical type of laundering procedure at 40 °C which was performed in a household drum washing machine. A two-bath procedure using ozone was the subject of the second investigated laundering procedure. The efficiency of compared laundering procedures were evaluated (washing performance and cleaning performance indices). Impact Factors for both treatments were collected and evaluated with the help of the LCA/LCI methodology.
Sustainability of agricultural production results in reducing the negative trends caused by both climate change and by incorrectly applied technologies for production, which aims to preserve the resource base and maintaining environmental quality. Soils are conditionally renewable natural resource but practically reconstruct in a very long time. Therefore, in order to preserve them relate to nonrenewable natural resources. At its core, soil, where they are intended for agricultural use are processed to meet the needs of people and thus change their properties. By applying appropriate ways of tillage and use the potential of plant residues, it is possible to control physical properties. There is a misconception and myth that getting high yields in agriculture can be maintained only with the addition of fertilizer and / or water. High investments made at the entrance of the agricultural production can easily be pointless, if the physical properties of soil are suboptimal or even below the critical level.The physical properties of the soil, it is essential for processing and has its mechanical structure. It closely depend on a number of other properties such as bulk density, ability to retain water, porosity, adhesion, resistance, etc., Which play an important role in the processing and to obtain sustainable yields.
Based on the function of the goal of the considering problem, there has been formalized an optimization mathematical model for road transport of citrus fruits. Also, there has been developed the combined system of the criterion optimality. In accordance with the optimization criterion, there has been developed formalization of the selected mathematical model, study of the parameters, and in response to the developed procedures, there have been selected the parameters and highlighted the value of a studying parameter at the probability level of P=0.95.
Agro-tourism a type of tourism, when the aim of tourist is to live like a local, work with him in the fields, have his meal on the table together with him, i.e. to become part of his family for a certain time period. In order to provide branding of tourism as “a rural tourism” in Georgia, with the support from the Shota Rustaveli National Science Foundation, the home page has been designed on the main web page of the Tourism Geo-Information Center (which is being in the process of constant updating), on which there will be placed the agro-tourism facilities of Georgia with the appropriate itinerary. Also, a single agro-tourism database will be set, which will be available on the Internet.
The main issues are considered in this topic: Modern production has both quantitative and qualitative flexibility, which is essential in the global market where there is a "dictatorship of the buyer". In such circumstances it is necessary to respond quickly to customer orders. This means that production should be able to quickly change the volume and range of products.
Production planning and control (PPC) system represents a set of decisions on the acquisition, utilization and allocation of resources with the ultimate goal to satisfy customer requirements in the most effective and efficient way. PPC system involves a considerable amount of parameters and synchronizing of a high number of components is a complex process, especially in present business environment where everything has to be decided fast and precisely under an enormous pressure of external factor that undergo through constant change, as so throughout the years a number of methods have been developed with the intention of optimizing the work of PPC systems. One of the methods for optimizing PPC systems which is also used in this case is simulation module for PPC which integrates the parameters involved offering the opportunity of experimenting and analyzing the different possible scenarios in order to find the one that delivers the best possible results without affecting the current actual system and with that reducing the cost and time needed to identify the most optimal solution.
Companies make use of sexual appeal in advertising more now than ever. The purpose of this article is to gain a better understanding of how men and women perceive sex in advertising. Articles suggest that young men are not as affected as young women concerning buying behavior and self-confidence by the sexual appeals in advertisements.
The use of erotic stimuli in print advertising has become almost commonplace in the advertising practices. But the employment of erotic communication appeals in advertising continues to be a controversial topic. While the use of such stimuli may draw additional attention to the ad, the outcome of the use of such high degrees of erotic stimuli may, in fact, be negative. Sexuality in advertising is a major area of ethical concern, through surprisingly little is known about its effects or the norm of its use. The article is focused on providing a basis for making ethical choices about the use of sexual appeals in advertising.
The concept of quality control is becoming more and more important in the field of official statistics. In the last decade many national institutes of statistics adopted a systematic approach to quality. The paper deals with the issue of applying the concept of statistical process control (SPC) to official statistics. Process approach allows developing and improving the effectiveness and efficiency of a quality management system to meet the needs of all stakeholders. In the paper we focus on:
– Identification of statistical processes and establishment of links between them and
– Tools and methods for managing the statistical processes.
Openness of education organizations can be considered as a component of information openness of society. The article overviews content fullness at official web-sites of vocational education organizations against the requirements of regulatory legal acts through the example of those in Sverdlovsk region. Problems arising during web-sites content provision were considered from legislative point of view.
There are a lot of disputes regarding the real potential and influence of online activism onto offline world events. In line with that the aim of this paper is to establish the relationship between online activism and potential for social activism in the events that are manifesting in the real world. For that purpose we have conducted a survey of a nationally representative sample of Serbia (around 1200 respondents). Online activism is measured through both usage of the internet as the main source of information, as well as usage of Facebook used as a tool for political participation. On the other hand, real world social activism is measured through belonging to different citizens and political organizations, as well as participation in different kinds of social protests. The results of our research revealed an interconnectedness between the intensity of online activism and the potential for offline social activism.
The Islamic State (IS) (arguably the most successful terrorist group ever, or at the very least, the terrorist group which has attracted the most media attention) has declared itself a state, seized territories, and implemented a quasi-government. Widely recognized by their black flag, white pickup trucks, and horrendous executions broadcast live; the IS is a terrorist organization that because of its goals, methods, and appeal to young people, is worrisome to global leaders and decision-makers.
But what do we know about the IS? How is it possible that such a phenomenon came into existence let alone became capable of threatening global powers, obtaining continued funding, staging military actions, and grabbing media attention as it has done so far?
To explain the above question one must look at many different strategic issues that were not managed properly and therefore allowed Abu Musab al-Zarqawi, a Jordanian dropout and petty criminal, to create such a deadly organization. Today the IS plays an important role in the Middle East and is capable of carrying out deadly terrorist attacks not only in its home region but also in Europe, the United States, and Asia.
The name, funding, controlled territories, roots, religious affiliation, and many other factors must be explained in order to fully understand the IS; the terrorist group of the 21st century.
Sustainable development has become a widely used concept and an important global issue. Enterprises aiming for sustainable development must combine economic interests with environmental and social needs, while keeping economic profit as a priority. A variety of different models of sustainable business issues have already emerged. The major challenges of enterprises include choosing particular model and assessing the sustainable development performance. The purpose of this article is to analyse and critically evaluate various models of enterprise’s sustainable development, identify advantages and limitations of existing models and propose procedural model suitable for manufacturing and service enterprises. The enterprises sustainable models will be analysed by covering economic, social, environmental and technological aspects of sustainability. Research will be carried out using analysis of scientific literature and synthesis of various approaches.
