Utjecaj strukturnih parametara tkanina na propusnost svjetlosti

Tkanina je tekstilni plošni proizvod sačinjen od minimalno dva, međusobno okomita sustava niti koji su međusobno isprepleteni po određenom pravilu, odnosno vezu. Ovakva struktura čini tkaninu vrlo heterogenim plošnim materijalom u kojemu volumne jedinice zraka između niti osnove i potke čine materijal poroznim. Poroznost tkanine ukazuje na udio pora u tkanini. Tkanina se može tretirati kao dvodimenzionalni ili trodimenzionalni materijal, a razlikuju se pojmovi otvorena poroznost i zapreminska poroznost. Propusnost svjetlosnih zračenja kroz tkaninu bitan je parametar kod razvoja tkanina za određene namjene. U ovome završnom radu odredit će se količina propuštanja svjetlosti kod uzoraka tkanina različitih strukturnih karakteristika. Utvrdit će se utjecaj veza, gustoće niti, debljine tkanine i drugih karakteristika na propusnost svjetlosti

ANALYSIS OF A NON-SUPERCELL TORNADO IN SOMBOR ON JULY 10, 2014

Around 14:00 UTC, on July 10, 2014 a non-supercell tornado-a landspout, formed and occurred within a convective cloudiness in the S-SW upper air flow and moved over Sombor (45°46' N, 19°06' E, h=89 m). Synoptic conditions, type of synoptic situation which caused the landspout event, CAPE, LI indices and adiabatic stability of the atmosphere have been analysed in this paper. An analysis of sounding measurements and satellite images has also been done. Based on field survey analysis and using the Fujita scale method (F-scale), damage estimates have been shown in order to determine the tornado strength. The three main objectives of this research are: 1) analysis of atmospheric synoptic conditions that caused the landspout development in northern Backa using the data obtained from upper air and surface maps; 2) investigation into the satellite images data and radiosounding measurements; 3) to determine the evolution of the parent cloud from which the landspout developed using these methods. This article therefore represents a contribution to understanding of atmospheric conditions which favour a suitable synoptic and thermodynamic environment for a landspout genesis and development

In memoriam: PROF. DR. DRAGIĆ TOMIĆ (1925-2019)

Professor Dragić Tomić, DSc, retired Full Professor of the University of Belgrade - Faculty of Forestry passed away on January 20, 2019.   Professor Tomić was born on May 4, 1925 in Jalovik in the Vladimirci Municipality near Šabac. He finished elementary school and high school until the sixth grade in Šabac. His education was temporarily halted during World War II when he volunteered to join the National Liberation Army, where he remained until December 1945. After demobilization, he completed his education. In 1946, he finished the VII and VIII grades of high school and in the same year enrolled in the Forestry Department of the Faculty of Agriculture and Forestry (Department of Silviculture). He graduated in 1950, achieving the highest grade in his defense of his final paper. During the third and fourth years of study, he was a volunteer demonstrator in Forest Entomology. Upon graduating, he was appointed junior teaching assistant at the Department of Forest Protection of the Faculty of Forestry in Belgrade. He was elected as a teaching assistant for the first time in 1954. After two re-elections as teaching assistant (1957 and 1960), he was promoted to lecturer in 1962. He defended his doctoral dissertation entitled "Ecology of Pine chafer (Polyphylla fullo L.) on the Deliblato Sands" in 1965, obtaining the title of Doctor of Forestry. He was elected to the position of assistant professor in the subject Forest Entomology at the Faculty of Forestry in Belgrade in 1965, associate professor in 1971, and full professor in 1977. Since the establishment of the department at the Faculty in 1966, in addition to Forest Entomology, he taught: Horticultural Entomology, Protection of Plantations on Eroded Areas, and for a short time, Wood Protection. He retired on September 30, 1990. He died at the age of 94.   Professor Tomić was a true expert. He published over a hundred scientific and professional papers in domestic and foreign journals, and the results of his work are still cited by many researchers. He had excellent knowledge of the world of harmful forest insects, and especially his favorite butterflies from the group of geometer moths (Fam. Geometridae), beetles from the group of cockchafers (Fam. Melolonthidae) and bark beetles (Fam. Curculionidae, subfamily Scolytinae), which he studied throughout his working life. His doctoral dissertation, which he defended in 1965, was a detailed study of the Pine chafer, a dangerous pest on the sandy terrains of our country, of which very little was known. He also studied other groups of harmful forest insects, both in terms of their ecology and harmfulness, as well as ways to effectively control them. His studies of harmful insects of soft broadleaves are very significant. First, he exhaustively studied and published papers on certain dangerous pests of poplar and willow, such as the small poplar borer, poplar clearwing moth, broad-shouldered leaf beetles of poplar and willow, and then, together with professors S. Živojinović and K. Vasić, he published the comprehensive paper "Harmful Insects of Soft Broadleaves" in two parts. He studied harmful insects in forest nurseries throughout his professional and scientific career. In addition to the extensive study of the Pine chafer, he studied other chafer species and provided the key for the determination of cockchafer larvae in the Deliblato Sands area. He also dealt with the fauna of bark-boring beetles and published papers on the fauna of this harmful group of insects on the mountains of Zlatar, Golija, Kosmaj and Kozjak. For many years, he studied geometer moths and published significant papers on the fauna of this group of butterflies of the Deliblato Sands, Mt. Goč, and finally the detailed paper "Fauna of Geometer Moths (Lepidoptera: Geometridae) of Serbia", published by the Serbian Academy of Sciences and Arts (SASA). He also investigated the harmful insects of urban greenery and studied the bionomy and ways of controlling some little known, as well as some allochthonous, harmful insects in Serbia.   Professor Tomić was an excellent professor and educator with extensive knowledge and experience that he selflessly passed on to his students, junior colleagues and fellow professionals. His lectures were always well attended, as they were interesting and amusing for students. He is remembered by his student because an exam with Professor Tomić rarely took less than an hour. He expected a lot from his students, but he also did his best to give them the requisite knowledge. Even as a full professor, at the request of his students, he gave tutorials. None of his students ever complained about his high demands.   Colleague foresters from the field often came to Professor Tomić for help or advice when they could not solve problems in forest protection. Professor Tomić had limitless patience for them. He would go to the field, give advice, write reports, and typically, he never sought financial compensation for his work or effort, something that is hard to imagine nowadays: he considered it his duty.   Professor Tomić will be remembered by all of us, his former students, colleagues and associates, as a good and generous man. He was quiet, calm, tolerant, patient, hardworking and just, always willing to help others. With the passing of Professor Tomić, the branch of forest protection has lost a great scientist and expert, and for the many who knew him personally, a true friend

The Phonoarchive of the Institute of Musicology SASA: A Product and a Protagonist of the State Science and Cultural Policy

The subject of attention is the relation between the content-specific and dependent archive of the Institute of Musicology SASA (Serbian Academy of Sciences and Arts), the research praxes in ethnomusicology and musicology directly connected with the archive, and state politics, which influenced those praxes. The analysis of the history and content confirms the importance of this archive not only for the purpose of studying national cultural history, but also for the history of the aforementioned disciplines. The collection of traditional music recordings, “ethnomusicological phonoarchive” is especially indicative. Focusing on that part of the archive, it becomes possible not only to perceive the methodological development of national ethnomusicology, but also to comprehend the politics of research in this field in Serbia – from the hierarchy of social and cultural environments and acoustic expressions, to the politics of analyzing the relation between music and identity. Given that the Institute of Musicology SASA has been the only state funded institution of that type ever since its founding, perceiving the causal bond between the traditional music collections and development stages of the Serbian society is expected. As a part of contemporary scientific policy, the usage and the development of the archive collections potential through digitalization and the affirmation of possibilities in the domain of applied ethnomusicology, will also be represented.Book of Abstracts.

Singing to the Accompaniment of the Gusle in Serbia: A Living Ancient Performing Art

A story about singing to the accompaniment of the gusle, an element of the Intangible Cultural Heritage (ICH) of Serbia inscribed in the Representative List of the ICH of Humanity in 2018, particularly regarding its safeguarding, is an illustration of the close connection between traditional folk art, education and science. In Serbia, the gusle – a simple, folk, singlestringed instrument – primarily accompanies songs about events from the legendary past, both from the distant and near history, of mythical and historical heroes. The key actor is the guslar – an epic singer who accompanies himself on the gusle. However, the presence of an auditorium – a social context – is an essential condition for this communication with ritual elements. Consequently, such art practice contributes to cohesive relationships in the community and becomes a constructive part of its identityEdited by European Music Council, Haus der Kultur, Bonn, German

ASSESSMENT OF THE ECONOMIC EFFECTS OF REENGINEERING IN SMALL AND MEDIUM-SIZED COMPANIES

As in any business, application reengineering quality primarily depends on the knowledge held by people who carried out activity reengineering, their skills and the ability to anticipate possible problems and devise steps. Evaluation of economic performance reengineering, particularly in small and medium-sized companies, is based on several well-known methodologies are widely used in practice. In this paper we will make an attempt to assess the effectiveness methodology improve to the extent that is reasonably used and applicable in daily practice. proposed methodology is particularly interesting in terms of small and medium-sized enterprises, which today form the basis of economic development of almost all national economic system

Gusle-making in Serbia between Tradition and the Market

The place of gusle among the Serbian traditional instruments is on the one hand determined by its subordinate role in the vocal-instrumental performances of epics, and, on the other hand, by its prestigious status in the national culture owing to the overall significance of this genre. The relevance of research of gusle-making was pointed to not only in the material changes in the instrument itself manifested accross time, but also in the earlier literature of ethnographic kind. Ethnomusicological approaches from the end of the 20th century and the beginning of the 21st century mostly deal with musical practice and, hence – with music and musicians, putting the phenomenon of instrument-making on the margin. Gusles as a part of traditional epic performance practice were also examined from the perspective of communication theory which, once more, left the topic of instrument making unexplored. Therefore, the 2017 Meeting of the ICTM Study Group on Musical Instruments and its main theme served as an impetus for the research of this missing aspect.SIMP *5.
