Many modern threaded joints especially in the oil and gas industry, must satisfy high requirements for steel mechanical properties of which they are made. To ensure efficient threading of such hard-to-machine materials (ultimate strength is more than 1250 MPa), it is necessary to use carbide cutting inserts with the negative rake angle at its corner. However, modern manufacturers of such inserts make them only with a zero value of the rake angle. This is due to the difficulty of profiling of the insert cutting edge. This article proposes the basics of such inserts automatic profiling which is based on the algorithm developed by the authors. It includes two corrective calculations of the insert cutting edge profile, namely: the radial displacement of the corner and the tangential displacement of the area forming the crest of the thread. As a result, the computer application with the input parameter of the rake angle and output parameter of the upgraded profile of the insert cutting edge is received.

Simulation in the production process represents the implementation of processes in real-time and space. Current trends are heading towards the implementation and expansion of various types of automated delivery systems in many industrial enterprises.

The conductometric study of ligand structure influence on the Pb(II) complexation with crown ethers in different solvents has been investigated. In this paper, the complexation reaction of macrocyclic ligand, 18-crown-6 (18C6), dibenzo-18-crown-6 (DB18C6), and Pb(II) cation was studied in different solvents: dichloromethane (DCM) and 1,2- dichloroethane (1,2-DCE). The effects of surfactant structure (Triton X-100 and Triton X-45) on the conductivity of the Pb(II) complex with 18-crown-6 and dibenzo-18-crown-6 ether have been investigated. The conductance data showed that the stoichiometry of the complexes in most cases is 1:1(ML). It is also demonstrated that the influence of crown ethers is deeply affected by the organic solvent used. In the solvents studied, the stability of the resulting complexes showed higher stability in dichloromethane comparing with 1,2- dichloroethane. Macrocyclic ligand 18-crown-6 showed more suitable for complexation of Pb(II) ions compared to dibenzo-18-crown-6. Adding a surfactant affected the higher absolute values of the conductivity of systems, but not the change in the stoichiometric ratio between a metal ion and macrocyclic ligand.

Even though pesticides constitute a very essential component of improved and modern agriculture, the abuse of pesticides has brought substantial poisoning worldwide, especially in developing countries. This review investigates the possible sources by which people are exposed to pesticides worldwide and the impact on their livelihood. The group who often are exposed to these chemicals includes, farm workers, children, farmers, and family members who have direct link to the pesticide application sites as well as persons who are exposed to these pesticides through the domestic use of waterbodies and consumption of foodstuff or crops sprayed with these pesticides. Central to this review is the critical discussions of the different scientific research findings on health effects and risks related to pesticides usage. Again, organophosphates and organochlorines pesticides are found in most of the pesticide contaminated sites and can remain in soil and waterbodies for a longtime. This work has also provided cases of incidence of carcinogenicity in humans, as a result of pesticides use. We concluded that, breeding or developing insect tolerant or resistant crops may curb the profuse use of pesticides in agriculture.

The research was carried out from April to July 2019, in Republika of Srpska. The sample was suitable. It was made up of
294 respondents aged between 15 and 73. The average age of the respondents was 22,92 years. Male respondents numbered 120 or 40,82%, and females 174 or 59.18%. Independent variables are gender and age. The dependent variable is the level of the cognitive component of the social attitude. Milosavljevic's Skala PARADOKHIP & BM-2006-02-26 was used to examine the levels of cognitive component of the social attitude. The aim of the research was to verify the hypothesis about the paradoxical Relationship of cognition and non-cognition in the cognitive component of the social attitude, according to which a greater scope of the cognitive component of the social attitude corresponds to an even greater extent of the experience of non-cognition (not-knowing) and vice versa. It has been confirmed that the greater scope of cognition in the cognitive component of the social attitude corresponds to an even greater extent of the experience of noncognition, regardless of the gender of the respondents. With the aging, there is also a growing awareness that a greater scope of cognition in the cognitive component of the social attitude corresponds to an even greater extent of the experience of noncognition, and the existence of statistical significance (p<.05) has been confirmed between the categories of subjects aged 15- 18 and 24-73.

The paper examines the current state and the possibilities of using contemporary approaches and tools in HelpDesk systems development with the aim to examine its disadvantages. Disadvantages are accurately analyzed and the paper gives clear guidance how to eliminate them. It has been noticed that current design and development approaches have their own advantages and disadvantages. The application of the unified approach that combines the best individual characteristics of the existing approaches enables development of an automated HelpDesk system that is capable of expanding its own expertise. By combining unified aspect approach with the zero tolerance model driven approach, a new innovative approach to the development of a wide range of expert systems is obtained. This innovative approach is characterized by the highest possible degree of modularity. The application of the aforementioned approaches has also enabled expansion and improvement of the existing expert systems used for servicing numerous companies operating in various fields of business.

It is beyond any doubt that victims of human rights violations are rarely in position to initiate court proceedings fighting systematic discrimination themselves, which makes the role of human rights institutions indispensable. This specific mandate gives rise to numerous questions, such as: to what extent state institution takes the role of the legal representative, what capacities should it possess, on what basis it selects the cases meriting court intervention, is court intervention equally suitable in all areas of human rights protection and which analyzed model from Europe or wider has proved to be the most effective? Article offers analysis of court interventions in federal states with complex government structure and multiple institutions mandated with human rights protection, be it Ombudsmen Institution or Equality Body, court interventions in states with single human rights institution, comparative practice present in various European states, as well as interventions of human rights bodies before European tribunals. Author outlines the legal framework, human resources, and administrative structure that need to be provided, so that court interventions would have the desired effect and generate positive changes. In this process, it is of paramount importance to respect existing legal traditions and intrinsic practices, which proved their practical applicability over time, while any attempt to use legal transplants, with a goal of hastily unification of national legal orders and imposing transnational jurisdiction, can only produce confusion and countereffects.

Razvojem informatičkih tehnologija, potreba za prenosom podataka zahtijevala je konstantno širenje kanala za prenos podataka i komunikaciju. Širenje interneta dovelo je do integracije različitih komunikacijskih servisa kao što su npr. video komunikacija, radio, TV. Samim time se generisala i velika količina podataka. U početku su prenosni mediji bili bakreni kablovi koji su podržavali prenos relativno malog prometa, dok u današnjici sve veću ulogu preuzimaju optički kablovi. Namjena optičkih komunikacijskih sistema jeste prenos signala velikim brzinama na velike udaljenosti, putemoptičkih veza. Za razliku od aktivnih komponenti koji se nalaze na strani operatera, korisnik kako bi uspostavio optičku mrežu, zahtijeva samo pasivne elemente. Razvoj optike doveo je do podjele udaljenosti postavljanja optičke topologije, tako se je pojavio FTTx.
