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.

This paper presents the impact of modern communication technologies on online learning of students. Communication technologies are in the center of research, especially their impact on online learning, which was trying to be avoided for so long. The prejudices that stood next to online learning were lifted. During Covid-19 lockdown online learning was salvation for tens of thousands of students who had the possibility to continue education when it seemed that the whole world around them seemed to have stopped. During preparation of this paper systematic approach has been used by studying pros and cons of online learning in 21st century and whether it provides an improvement in the overall education of students and teachers. Education is the main foundation and key to success of each individual. With the development of communication technologies this has been enabled for people living far away from big cities. Trough the usage of software platforms for communication and collaboration learning has been enabled via audio and video meetings and data storage, all in one place.

Corruption is one of most destructive and complex problems nowadays. Its results negatively influence business environment, political stability and level of standard. On global level corruption presents major barrier in international trade. Governments of many countries have passed national program for battling corruption. The total cost of fraud will be difficult to objectively assess, in particular, will be difficult to calculate the indirect damage caused by fraud. Some frauds will never be discovered. It is estimated that organisations around the world on average lose 5% of annual revenues to fraud. Small reduction in costs due to fraud can significantly increase profit of organisation. The International Organization for Standardization has developed standard ISO 37001 – Anti-bribery management systems. It’s the International Standard that allows organizations of all types to prevent, detect and address bribery by adopting an antibribery policy, appointing a person to oversee anti-bribery compliance, training, risk assessments and due diligence on projects and business associates, implementing financial and commercial controls, and instituting reporting and investigation procedures. Providing a globally recognized way to address a destructive criminal activity that turns over a trillion dollars of dirty money each year, ISO 37001 addresses one of the world’s most destructive and challenging issues head-on, and demonstrates a committed approach to stamping out corruption. Paper presents research on level of corruption in Bosnia and Herzegovina, comparison with level of corruption in other courtiers, as well as correlation with the global competitiveness index. Moreover, paper presents methodology for development and implementation of system for battel against corruption in companies. Research results bring new scientific facts and findings in battle against corruption and methodological process of implementation of system for battel against corruption in companies.

The collapse of communism in the 1990s resulted in the escalation of nationalism in Europe. Nationalism has until the present day remained the only political idea which is judged on the basis of its abuses and occurrences such as, chauvinism or nazism. The injustice is that much greater, because nationalism, according to its original meaning, disapproves of those negative forms into which it can evolve. The war in the former Yugoslavia, the conflicts in the countries of the former Soviet Union, greater desire for independence, both within the European Union itself and its member states (Great Britain, Wales, Scotland, Catalonia, etc.) are the examples of what a political character of nationalism can be, and in which direction it can develop depending on the interests of the political authority which created and governed it.

“Cyber Crime in Pakistan; Detection and Punishment Mechanism” addresses improvement of public health and safety policies by focusing on enhancing knowledge about cybercrime, women victimization, the pattern of time spent on the internet, sexual harassment and cyberbullying and the effect of sociodemographic factors on cybercrime. A quantitative, self-selected research study designed by the researcher and utilizing a voluntary, anonymous internet survey consisting of open and closed-ended questions targeted students attending large universities in Pakistan (N=400), based on Routine Activity Theory (RAT). The results were analyzed through SPSS via directing descriptive statistics, Cronbach’s alpha, and regression analysis to confirm the validity and internal consistency of data and verification of the hypotheses. Results depicted women represent the largest group impacted by cyber abuse. Single women, young adults, and employed students demonstrate increased rates of victimization. Frequent usage of social media may account for increased victimization for women. Time spent online and deficient knowledge of cyber protection measures are positively correlated with digital victimization. Respondents report on inadequate effective and affordable cyber protection and ineffective responses by agencies to cybercrime. Based on the results garnered, and supported by Public Policy Theory, Cybersecurity policies have been proposed to Pakistan’s government.

Education must be obtained and guaranteed by the government with quality and equitable services in all regions in Indonesia. Geographic information systems become one of the solutions that can help the process of equitable education and help the government take appropriate actions. This study discusses how the development of a website-based geographic information system that can be used to map the distribution of educational data in the city of Bandung using the Rational Unified Process (RUP) and Unified Modeling Language (UML) methods for system modeling. The process of making maps in this study uses Quantum GIS (QGIS) software with database storage using PostgreSQL. The output target of this study is in the form of a geographic information system website mapping educational data distribution in the city of Bandung. This website is created as a graphic summary dashboard based on the spatial field of education so that the public and government can easily draw conclusions about the distribution of existing education such as knowing the balance of the number of schools, teachers and students in an area that can affect the quality of teaching and learning activities in schools and the quality of education in that area.

Heavy metals are considered to be one of the major contaminants of water in recent years due to their non-biodegradable property; hence making them toxic and bioaccumulate to living organisms. Conventional methods such us chemical precipitation, physical treatment through ion exchange are used for removing heavy metal ions from water. These methods are expensive and attributed to incomplete metals removal and high cost of treatment. In recent years, researchers have found alternative low cost and effective method for removal of toxic metals through biosorption process using biological materials. Moringa oleifera seeds is one of the biological materials which has effective adsorption capacity for removal of heavy metals from water and wastewater. In this article, the seeds of Moringa oleifera seeds as a low-cost biosorbent for removal of heavy metals is presented. Moringa oleifera seeds is inexpensive material that contains amino acids. The amino acid is a major constituent of the functional groups that aids in greater ability of heavy metals removal through metal ion exchange or complexation, which is mainly affected by pH, biosorbent dosage, and contact time. Moringa oleifera seeds residues have a greater capacity to absorb heavy metals in a single solution compared to multi ion solution.

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.
