Among the various methods for water purification and treatment from contaminated industrial pollutants, one of the most used is the adsorption methods based on activated carbons. The purpose of our study is to investigate the correlation between the porous texture and chemical nature of the surface and sorption capacity of the activated carbon, obtained based on lignite coal. The object of the study is also to determine its effectiveness as a sorbent for Cd-ions purification of contaminated industrial water. The obtained data from the conducted investigation show that the adsorbent based on such kind of activated carbon has good qualities for water purification from various pollutants and heavy metals

Once a part of the Soviet Union, a backwater country, Georgia in a couple of years flips the script and rushes into tourism industry as one of the most popular emerging destinations on the Black Sea coast. With unprecedented number of tourists spotlighted by the leading international journals Georgia wins hearts of millions and becomes a revelation for the USA and Western EU countries.
This paper assesses current situation in Batumi Port that serves small cruise ships and explores potentials of cruise tourism development based on statistics, industry experts and investors reviews. The article uses a mixed method, a combination of qualitative and quantitative data analysis.
The findings show how Black Sea region will benefit from country’s cruise tourism development. Results of the study can be applied as basis for investment analysis of Georgian cruise industry
The quality of ambient air is a noticeable demonstration because the ambient air plays a cardinal preface on the human activities and most of environmental processes. The monitoring of the quality of air is an important part of the pollution control because the ambient air was confirmed as an affected branch on the earth from both anthropogenic activities and natural phenomena. In the existing investigation, there were expected to test the selected important air quality parameters of the ambient air at around the Peradeniya region in Sri Lanka which is known as relatively populous region with the traffic. The ambient air samples were collected through a glass fiber filter paper which was attached to the high volume air sampler and both PM10 concentration and concentration total suspended particles (TSP) of the ambient air were determined using weight differences of air collection bottle and filter paper. Beside of that the lead (Pb) concentrations and NOX concentrations of the ambient air were investigated using hot acid extraction method while having the contribution of atomic absorption spectrometer (AAS) and of absorbing method in to a liquid with the aid of UV- visible spectrometer. As the results, there were obtained 0.0141 ppm of PM10 concentration, 0.0214 ppm of total suspended particles (TSP) concentration, 0.151 μg/m3 of NOX concentration and 0.015μg Pb/ m3 of lead (Pb) concentration of the ambient air at around the Peradeniya region at that moment. When comparing of those results with the air quality standards and norms, it was identified the non hazardous atmosphere at the selected region at that occasion.
Regulation and importance of practical education while studying-application on the Higher Vocational College Postojna and Educational Centre of Modern Technologies-Sloveniapg(s) 56-58
The paper deals with importance of practical education and training in system of education, its legal regulation in Higher Vocational Education Act and different regulations in Slovenia. Vocational education and training – VET- is a great way to improve quality and efficiency of study, making students more prepared for working conditions and desirable to employer. EU integration made new possibilities to improve it with programs like Erasmus+ and financing different projects regarding VET. One of the projects is presented in this paper as an example of a good connection between the school and the local economy through the construction and operation of a manufacturing learning laboratory, which seeks to reduce the gap between education and the labour market in one of the Slovenian regions.
Massive open online courses have a significant impact on the cross-cultural communication. More and more online courses become a part of modern university curriculum. This creates a way to share knowledge not only between different scientific facilities but provide an opportunity for students to take courses from top rated universities free of charge. Our research deals with the way to bring massive open online courses into cross-cultural educational field. The article deals with the translation’s editor work features in preparation for massive open online technical course to voice over and broadcasting on the example of the most popular programming course in the world “CS50 2019” (Harvard University). The main problems faced by the translation’s editor are highlighted. A step-by-step plan for the translation’s editor is suggested.
Emerging technologies in the global world are posing new challenges to education in all degrees. Especially relevant is the challenge posed by the competency approach. The development presents an understanding of the dependency summative-competencies underlying the TREAM strategy
The present work tries to present possible variants for developing the creative beginning through overcoming the cognitive dissonance. It looks for balance between the traditional pedagogic interaction aiming academic achievements in certain strict framings and achieving creative manifestations. There are accents not on following algorithms and rules but rather on human behaviour in school environment, modeled according to the learner’s abilities in order the cognitive dissonance to be overcome.
The determining role of the spiritual and moral potential of a person in the process of rational choicepg(s) 67-70
The ratio, mutual influence and interdependence of the most important elements of the human potential and the HIGHEST SPIRITUAL principle of a person are considered in this paper. The importance and role of the human potential in achieving the UN sustainable development goals. Potential of a HUMAN and its perspective use in the implementation of INDUSTRY 4.0 achievements
This paper gives the presentation of the engineering ethic course at The University of Montenegro.
Several events that as engineering, but not only as engineering, solutions had catastrophic consequences influenced the popularization and more and more frequent considerations of the engineering ethic, hence it forced the engineering profession to face with deficiencies in technical and executing practice, as well as the standards of etic.
There are few universities in the world in the area of technical faculties where an engineering ethic is studied. The syllabus of engineering ethic at The Faculty of Mechanical Engineering in Podgorica has been divided into six parts, according to the principles and standards of traditional ways of the studying engineering ethic.
Analysis of mcgregor, aldelfer and murray’s motivation theories and their applicability in the militarypg(s) 76-78
The article discusses some of the content motivational theories, examining their applicability in military organisation. The purpose of the report is to analyse the theories of McGregor, Aldelfer and Murray rather than indicate the best approach for motivation. The results of the analysis will contribute to a clearer understanding of military motivation and provide guidance that commanders and chiefs could use to enhance their own motivational style.
