Ili？ An？elija ？.,Risti？-？urovi？ Jasna L.,？irkovi？ Sa？a T.
Nuclear Technology and Radiation Protection , 2006, DOI: 10.2298/ntrp0601029i

Abstract: In an accelerating region of a cyclotron, an ion makes a large number of turns; thus, its n the Runge-Kutta method of the fourth order with the adaptive time step has been developed. The accuracy requirement is simultaneously set on position and momentum calculation. Magnetic fields used as inputs, have been evaluated in terms of the radial fluctuations of the orbital frequency, i.e. their isochronisms. Ion trajectory tracking has been performed for the following four test beams: H-, H+3, 4He+, He+, and 40Ar6+.

Ili？ An？elija ？.,Risti？-？urovi？ Jasna L.,？irkovi？ Sa？a T.
Journal of Automatic Control , 2006, DOI: 10.2298/jac0601005i

Abstract: In an accelerating region of a cyclotron an ion makes a large number of turns; thus its tracking requires fast as well as highly accurate computation. Computer code, based on the adaptive time step fourth order Runge Kutta method, has been developed. Accuracy requirement is set simultaneously on the position and momentum calculation. Magnetic fields used as input, have been evaluated in terms of the radial fluctuations of the orbital frequency, i.e. their isochronism. Ion trajectory tracking has been performed for the four test beams: H-, H2 +, 4He+, and 40Ar6+.

Focusing limit of a cyclotron: Axial betatron instability against beam dynamics approach
？irkovi？ Sa？a T.,Risti？-？urovi？ Jasna L.,Ili？ An？elija,Ne？kovi？ Neboj？a
Nuclear Technology and Radiation Protection , 2006, DOI: 10.2298/ntrp0602040c

Abstract: In an isochronous relativistic cyclotron, axial defocusing of a beam caused by the radial growth of the isochronous magnetic field is compensated by the azimuthal field gradient introduced by sectors. The focusing capabilities of sectors set the maximum ion energy obtainable from the machine. Usually, the focusing limit of a machine is determined by using the criterion for axial beam instability evolving from the equations of betatron oscillations. The obtained value of the focusing limit is approximate because the equations of betatron oscillations it originates from are approximate as well. The accurate value of the focusing limit is obtained by simulating accelerated beam dynamics in the extraction region. It is shown that the focusing limit of a cyclotron resulting from the two methods could differ for more than 9%. The suggested third method for focusing limit computation relies on the beam dynamics simulation along the critical equilibrium orbit rather than the acceleration orbit and thus it is less time consuming although equally accurate.

THE RESULTS OF BULLS PROGENY TESTINGS AT APKM
Milutinovi？, Ignjat,Pulja, An？elija
- , 1968,

Abstract: Sa？etak The cattle production on Kosovo and Metohija is still quite backward according to the average cattle production in Yugoslavia. There are many reasons for this, but the most important are: the breed of cattle in the Region, and the big percentage of cattle which exist on the small, private farms, where is unpossible to keep the management on high level. In spite of this, after the second world war up to now, the improvement was quite big. The greatest contribution to this improvement was from the artificial insemination (that is in practice since 1967, and now, there are about 50.000 heads of different crossis between native and high productive cattle), and the bulls progeny testing. Since 1957 several bulls were tested on the reproductiv ability, and the majority gave good descendants regarding to milk and meat production. The data in this paper are related to 10 bulls i. c. 2 ？Danish red“, 4 ？Montafon“ and 4 ？Simental“ and about 1.000 progenies. They where not degenerative sings on the progenies, what is very important for further work. The majority of progenies was graded ？Very good“ and ？Exelant“, and this is to expect a slow improvement in the cattle productivity

Work Experience of Social Workers with Roma Families
Elija？, Mirna,Laklija, Maja
- , 2014,

Abstract: Sa？etak Roma families are facing different problems connected with life in social exclusion, poverty and closed communities. Because Roma’s specific way of life which is much different from other population and their exposure to numerous risks, the aim of this study was to gain insight into work experience of social workers with Roma families in Social Welfare Centres (SWC) Zagreb. The study was conducted on a sample of 9 social workers. A semi-structured interview was conducted with each of the participants, and the results were obtained by qualitative content analysis. Regarding the reasons of SWC treatment of Roma families, the following categories were given: achieving material benefits, notices by other institutions and family violence. Regarding the social workers cooperation experience with Roma families, most of the participants describe it as a positive, describing their experience of working and contacting with members of Roma families. Regarding their cooperation experience with Roma families, the following category was given: challenges of working with Roma families, such as: problems in contacting members of Roma families, tendency to manipulation and giving socially desirable answers, the need to adjust professional work, dropout prevention, unemployment and unresolved status issues. Under a proposal to improve professional work of social workers with Roma families, participants expressed a need for additional professional education and knowledge about the life of Roma families and their tradition

Abstract: Sa？etak Budu？i da se romske obitelji suo？avaju s razli？itim problemima koje nosi ？ivot u socijalnoj isklju？enosti, siroma？tvu i zatvorenim zajednicama koje se zbog svoje specifi？nosti u mnogo？emu razlikuju od ostalog stanovni？tva te su izlo？ene brojnim rizicima, cilj ovog istra？ivanja je bio dobiti uvid u iskustvo rada socijalnih radnika CZSS-a Zagreb s romskim obiteljima. Istra？ivanje je provedeno na uzorku od 9 sudionika socijalnih radnika zaposlenih u sustavu socijalne skrbi. Sa svakim od sudionika proveden je polustrukturirani intervju, te su rezultati dobiveni kvalitativnom analizom sadr？aja. Vezano uz naj？e？？e razloge zbog kojih su romske obitelji u tretmanu CZSS-a dobivene su sljede？e kategorije: ostvarivanje materijalnih davanja, dojave od strane drugih institucija i nasilje u obitelji. ？to se ti？e iskustva suradnje s romskim obiteljima, ve？ina sudionika ga opisuje kao pozitivno opisuju？i sam do？ivljaj procesa rada i kontakta s ？lanovima romske obitelji. U vezi s iskustvima suradnje socijalnih radnika s romskim obiteljima dobivena je i kategorija izazovi rada socijalnih radnika u radu s romskim obiteljima koja se odnose na njihov specifi？ni stil ？ivota, isporuku i odazivanje na upu？ene pozive CZSS-a, sklonost manipulaciji i davanju dru？tveno po？eljnih odgovora, potrebi prilagodbe stru？nog rada, preveniranju napu？tanja ？kolovanja, nezaposlenost te neimanje statusa hrvatskog dr？avljana i neposjedovanje osobnih dokumenata. U okviru prijedloga za unapre？enje prakse djelovanja socijalnih radnika u radu s romskim obiteljima izra？ena je potreba kontinuirane dodatne edukacije socijalnih radnika u podru？ju produbljivanja razumijevanja problema Roma i dodatnih znanja o ？ivotu romskih obitelji i njihovim obi？ajima

American Journal of Analytical Chemistry (AJAC) , 2013, DOI: 10.4236/ajac.2013.41006

Abstract:

Tembotrione is herbicide which belongs to the triketone group of herbicides. It’s registered as a selective, post-emergence herbicide developed for the control of a broad spectrum broadleaf and grassy weeds in corn. There is little information about tembotrione because of his short presence in the market. Due to its ever wider application, it is important to know the details of its chemical characteristics and redox processes, including biogeochemical transformation and migration after application to agricultural land, which could contribute to its efficient and safer application. In this paper we examined voltammetric behavior of tembotrione using Silver/Amalgam (Ag/Hg) electrode. For the investigation of electrochemical behavior we used the cyclic voltammetry technique, with conventional three-electrode cell and electrochemical workstation. During the experiment pH values of solution varieties while constant concentration of tembotrione was maintained. Cyclic voltammograms were recorded at pH values 6, 8, 10 and 12, at which tembotrione was electrochemically active. At this pH values two signals were observed. Optimum pH value, at which the current intensity was greatest, was 12. Obtained results provide relevant information on the electrochemical behavior of tembotrione, which can serve as a basis for the development of electrochemical techniques for the removal and degradation of this pesticide in the environment.

POSSIBILITIES AND PROBLEMS OF TOURIST SECTOR IN EMPLOYMENT STIMULATION ON THE TERRITORY OF VOJVODINA
Tamara GAJI？,An？elija Ivkov D？IGURSKI
Revista de Turism : Studii si Cercetari in Turism , 2010,

Abstract: In the 1980, tourism went through a relatively high degree of rise and it became an important factor of national economy, showing its vitality in the age of unstable economic and monetary movements, and in most part, it stood out as a part of economy that affects the economic activation of human resources to a large extent, so, in that way, it alleviated the unemployment problem. However, despite all claims that human capital is the biggest value of service sector, in reality that attitude is not supported enough. In this paper, there was an attempt to point to a number of problems connected to human resources in tourism, with a view of current state of tourism development and its effect on work contingent in Vojvodina, as one of developed trade and economic parts of Serbia. Exactly at the moment when tourism is becoming the leading service activity of the 21st century, with indications that it is one of the best ways for economic recovery of the country, in the first place an activating demographic factor, contradictory data appear, in the sense of negating positive effects of tourism through the fact that, besides all the tendencies, the number of employees in this activity is not rising, as it was expected.
