A REVIEW OF MECHANICAL PROPERTIES OF DIAMOND-LIKE CARBON COATINGS WITH VARIOUS DOPANTS AS CANDIDATES FOR BIOMEDICAL APPLICATIONS

Author(s): Krzysztof Jastrzębski,Aleksandra Jastrzębska / Language(s): English / Issue: 22/2017

In the modern world, there is an increasing demand for implants, and technologies connected with their manufacturing. One of the possible paths of their development relates to the use of diamond-like carbon coatings (DLC) for the improvement of surface properties of the biomaterials used for implants. Further improvement of the mentioned properties can be induced by means of doping of the coating. Among the elements which are under current investigation of researchers, the following can be placed: Ag, Si, F, Cu, Ti, Ca and P. This paper reviews previously published experimental data concerning mechanical and physicochemical properties of DLC coatings doped with Ag, Si, Cu, Ti, Ca, F and P as candidates for biomedical applications. Although plenty of articles are published in the mentioned field, the differences of coatings’ synthesis techniques, various sources of dopants and substrates, as well as conducted experiments make no consistent view about a possible solution for their future implementation in medicine. Some of the selected dopants (Cu, Ca, P), still require better characterisation of mechanical properties. There is a necessity to conduct studies of mechanical and physicochemical properties of DLC coatings doped with these elements. This will enable adjustment of the necessary technological parameters to biomedical requirements.

Author(s): Mustafa Kemal Topcu,Murat Mala,Selim Müslüm / Language(s): English / Issue: 2/2015

With the end of the Cold War, the static environment, characteristic of thebipolar world, has changed quickly into a dynamic and complicated environmentwith new actors. These changes have also affected the countries’ armed forces andnew approaches to procurement/acquisition come into progress. After the Cold War,countries have focused on responding to changing threats with their decreasing defensebudgets. In this study, acquisition models and their effects on Turkey’s technologyacquisition and defense industry are evaluated. The evaluation is performed basedon criteria such as contribution to national economy, customization, acquisition cost,time and risk, life cycle cost, and technology acquisition. Major acquisition modelsin this study are determined as direct procurement, production under license, jointventure, indigenous development, production via international consortium. Finally,it is observed that the best model is indigenous development while the others willserve as technology acquisition for indigenous development.

A SURVEY OF PERSONAL PHYSICAL SECURITY AWARENESS IN STUDENTS IN SELECTED UNIVERSITIES IN KENYA 1990-2019

Author(s): Felistus Kinyanjui,Anthony Manyara / Language(s): English / Issue: 2/2020

The end of the Cold War brought with it changes in the international security, with an escalation in intra-state conflicts, characterized by violence perpetuated by discernable and not so discrete foes. This challenge broadens dimensions of security to include human, social, economic, political, and environmental aspects which provide referent objects which are securitized. In line with securitization, a response to the asymmetric wars configured in terrorism whose preference is to attack“soft targets” such as people on holiday, revellers, shoppers, worshippers, and of particular concern to this study, university students. Unlike critical infrastructures which are well guarded by armed personnel, universities are core soft targets made of intellectuals and their trainees, who have bare military training and any inkling on how to respond in case of a terrorist attack. This makes such institutions susceptible as they hold tens of thousands of persons at any given time, making them a strategic attraction and target for terrorist aimed at causing maximum damage and fear among civilian populations.

ABOUT CIVILIAN MILITARY EDUCATION IN SECONDARY SCHOOLS IN POLAND. AXIOLOGICAL ASPECTS OF THE FUNCTIONING OF MILITARY CLASS STUDENTS BASED ON AN ANALYSIS OF THE RESULTS OF OWN STUDIES

Author(s): Ilona Urych / Language(s): English / Issue: 2/2018

The present article concerns civilian military education in secondary schools in Poland. The article presents the results of the author's own pilot studies on the axiological aspect of the functioning of military classes in secondary schools in Poland. The objective of the article is to specify the characteristics of the axiological aspects of the functioning of students of military classes based on an analysis of the results of the author's own studies, with particular focus on the interests, dimensions of development of personality traits, and the objectives of the respondents. The research method that was used was a diagnostic survey, the technique was a poll, and the research tool was a questionnaire. After a short description of the origins of military classes and of the research methods used, the authors analyse the axiological dimension of the functioning of the respondents: their interests, the directions of development of their personality traits, and their objectives. The conclusion contains answers to the research problems and a comparison of the values of the students of military classes to the values shared by young persons determined in contemporary studies in Poland.

About the Effectiveness of Several Dissimilarity Estimators used in Damage Assessment

Author(s): Vasile Iancu,Gilbert-Rainer Gillich,Cristian Paul Chioncel / Language(s): English / Issue: 3/2016

This paper introduces a robust method for vibration-based damage assessment, which is based on a mathematical relation contrived by the authors that involves the frequency shifts, the damage size and position. Databases containing damage indicators for all possible damage scenarios, for three types of beams, were developed by involving this mathematical relation. The proposed damage indicator is expressed using the relative frequency shifts. The damage location and severity can be assessed if the relative frequency shifts are derived from measurements at the initial state and periodically afterwards. The paper investigates the effectiveness of several dissimilarity estimators, to find damage involving frequencies measured without and in the presence of noise.

Access to Finance of the Macedonian Companies in the Post-Crisis period

Author(s): Meri Boshkoska,Spire Lazaroski / Language(s): English / Issue: 3/2016

In this paper we analyzed the liquidity of the companies, the plans for the future cash flows and questions related to the new law regarding the financial discipline. Main questions addressed here are the number of difficulties related to the sources of financing the current and the developing activities of the companies in Macedonia. The analysis is undertaken by using statistical techniques and models. The results suggest that in the post-crisis period the companies are facing with number of difficulties of providing financial resources for the current and the developing activities where the most significant source of finance are the bank credits. Also, the results suggest that delayed payment of claims, the legislative and the high level of interest rate are the most common factors that restrict the access to finance of the Macedonian companies.

Account books of the Musical Chapel of Lviv Uniate Bishop Leon Szeptycki (1760–1779)

Author(s): Ivan Yuriyovych Kuzminskyi / Language(s): English / Issue: 3 ENG/2018

This article explores the newly discovered account books of the Lviv Uniate Musical Chapel of the Bishop Leon Szeptycki. The main stay of this musi­cal chapel was the architectural complex of the Cathedral of St George in Lviv. Today, two account books are stored in the department of old books and manuscripts of the Andrey Sheptytsky National Museum in Lviv in the archives of the Lviv bishops; they cover the years 1760–1779. In the first two parts of the article, the author investigates the issues of the founding of the musical chapel and its place of activity. In the third part, there is a list of musicians who were members of this chapel over the years. In addition to the names and surnames, their positions, years of employment, musical instruments which they played and details of their biography are indicated. In the next part, there is a list of pupils of the chapel. It appears that the total number of pupils ranged from 2 to 14. Adult musicians and pupils played various instruments: harpsichord (“kla­wicymbaly”), clavichord (“klawikort”), organ, violin, alto, viola da gamba (“kwartviola”), cello (“basetla”), oboe, bassoon, trumpet and horn; there were singers as well. In the fifth part, the author specifies in what way the Lviv Uniate musical chapel was financed. In the next part, both the church and the secular musical repertoire of the musical chapel are described. In this section, also information from the Warsaw periodicals are used. In the seventh part, the collaboration of the Uniate music chapel with other chap­els and monastic orders, Jesuits, Dominicans and Conventual Franciscans is explored. In the last part, the author examines the information about the human settlements that are found on the pages of the account books.

ADATOK A KÁRPÁT-MEDENCEI, AGANCSBÓL FARAGOTT ÍJMARKOLAT LÉCEK ÉRTÉKELÉSÉHEZ - SZENTES-DEREKEGYHÁZI OLDAL, D-3 TÁBLA 6. SÍR

Author(s): Ádám Biró,Péter Langó,Attila Antal Türk / Language(s): Hungarian / Issue: 1/2010

Within the framework of the project of the Archaeological Institute of the Hungarian Academy of Sciences and the Institute of Genetics of the Szeged Biology Centre, titled “Archaeogenetics in the research on the ethnogenesis of the Hungarians”, a number of tenth-century cemeteries, incompletely investigated in the 20th century, have been re-investigated. In September 2002, a new excavation was carried out by Péter Langó and Attila Türk at the site of “Derékegyházi oldal, Berényi B. 129. tanya földje” southeast of Szentes, in the Great Hungarian Plain, originally investigated by Gábor Csallány in 1940 (Fig. 1.1–2). During the successful identification of the site four new 10th-century graves were found, which complete the cemetery (Fig. 2.1). The graves of eight buried individuals were oriented to west-northwest and were placed roughly in a row. Based on the grave-goods, the burials can be dated to the mid-third or second half of the 10th century AD, which was confirmed by radiocarbon dating as well.
