Доминантне струје у истраживањима музике у Србији: Преглед ране историје Музиколошког института САН (1947–1965)

This paper is dedicated to the investigation of the initial period of the Institute of Musicology SAS, the first scientific institution of this kind in Serbia (and Yugoslavia), in order to give an insight into the development of national musicology and ethnomusicology. The results of earlier research about the topic have been expanded by means of the analysis of documents from the archive of the Institute of Musicology SASA. The organization of the Institute’s functioning, general research orientation, key topics, methodological choices and the significance of individual researchers were considered in detail. This diachronically oriented overview of research into music throughout the 20th century enabled us to pointing out the continuities and innovations after World War II and the Institute’s foundation.Рад се бави историјатом српске музикологије и етномузикологије на основу анализе деловања Музиколошког института САН(У), једине научноистраживачке институције усмерене на проучавање музике у Србији. У фокусу је почетни период рада Института – две деценије непосредно после Другог светског рата (1947–1965). Основне изворе чинила је административна документација ове научноистраживачке установе. На основу ње је разматрана организација рада Института по појединим одељењима (Одељење за фолклор, Историјско-архивско одељење, Одељење за општу музикологију), као и деловање сталних и „спољњих“ (хонорарних) сарадника. Указано је на функције истраживања различитих музичких пракси у то време, кључне теме по областима, методолошке одабире, а осветљени су и утицаји појединачних личности. На основу увида у разматрања музичких појава пре Другог светског рата у закључку су сагледани континуитети и дисконтинуитети, као и појава иновативних истраживачких пракси и подухвата. Поред уочавања доминантних струја у српској музикологији и етномузикологији у дужем временском периоду, рад има за циљ потцртавање утицаја процеса институционализације на обликовање ових дисциплина у националним оквирима

Opportunities for sustainable development of rural settlement area of the Timok vineyards

Space of the Timok vineyards with rural communities in its geospatial coverage has exceptional natural resources with a range of characteristics in terms of environmental, cultural and anthropogenic values. Regardless of the prominent potential, development restrictions in this area are numerous. Empirical research shows that over the past decade have survived numerous inherited and generated new problems of ecological and socio-economic status of rural settlements. The cumulative effect of these processes on the local level as advanced environmental degradation and negative habitation demographic trends, which is at the regional and national level deeper and more complex development problems

Logistic process indicator (LPI) as the measure of infrastructural and regional development

Logistics represents a network of services that support the physical movement of goods, international trade and commerce within borders. The volume of international trade highly depends on factors facilitating trade and contributing to reducing its costs. Logistic is affecting the speed of globalization through optimizing the supply chain. Furthermore, this interdependence is the reason why the improvement of logistic is seen as an essential element of the regional and global development. The main aim of this study is to investigate the impact of key dimensions that affect the logistic process indicator (LPI) and to highlight their importance by applying the adequate methodology of its modeling. The evaluation of the LPI is performed using variables that include customs, infrastructure, ease of international shipments, logistics services quality, tracking and tracing and timeliness. Parameters have been collected for the period from 2007 to 2018. The extensive research is considering the data from 151 country in order to perceive the global level of the LPI. Outcome of the multiple linear regression is used to underline developed segments of the logistic process and those segments of the process that need to be further developed

Molekularna identifikacija i karakterizacija dvojedarnih Rhizoctonia spp. prouzrokovača crne truleži korena jagode u Srbiji

Strawberry production is a popular, fast-growing agricultural business in Serbia. Its cultivar selection has been changing fast, following market demands. One of the limiting factors of strawberry production worldwide is black root rot, primarily caused by binucleate Rhizoctonia. Recently, outbreaks of black root rot of strawberry have occurred in Serbia and the estimated disease incidence was up to 30%. Isolates of binucleate Rhizoctonia AG-A were recovered from symptomatic strawberry plants, and characterized on the bases of morphological, molecular and pathogenic features. Despite their uniform morphological characteristics, the isolates demonstrated genetic variability within ITS rDNA, grouping into three different phylogenetic sub-clusters which comprise AG-A isolates originating from Italy, Israel, Japan and the USA. The binucleate Rhizoctonia AG-A from Serbia exhibited uniform virulence on strawberry after inoculation of daughter plants and detached leaf petioles, as well as on seedlings of bean, carrot and sunflower, while they were non-pathogenic to wheat, maize, tomato, pepper, tobacco, cucumber, lettuce, peas, cabbage, rapeseed and sugar beet.Proizvodnja jagode je popularna grana poljoprivrede u Srbiji koja se brzo razvija. Sastav sorti uključenih u proizvodnju podleže stalnim promenama u skladu sa zahtevima tržišta. Jedan od ograničavajućih faktora u proizvodnji jagode širom sveta je crna trulež korena, bolest koju najčešće izazivaju dvojedarne vrste roda Rhizoctonia. U Srbiji je poslednjih godina nekoliko puta zabeležena pojava crne truleži jagode uz učestalost koja je iznosila do 30%. Iz biljaka jagode sa simptomima izdvojeni su izolati dvojedarne Rhizoctonia AG-A i okarakterisani na osnovu morfološih i molekularnih osobina i patogenosti. Uprkos uniformnim morfološkim osobinama, izolati su ispoljili genetičku varijabilnost na osnovu sekvence ITS rDNK, grupišući se u tri različita filogentska sub-klastera koji su obuhvatali isolate iz Italije, Izraela, Japana i SAD. Izolati dvojedarnih Rhizoctonia AG-A poreklom iz Srbije ispoljili su uniformnu virulentnost na jagodi nakon inokulacija živića i fragmenata lisnih peteljki, kao i na sejancima pasulja, mrkve i suncokreta, dok nisu bili patogeni za pšenicu, kukuruz, paradajz, papriku, duvan, krastavac, salatu, grašak, kupus i šećernu repu

Psychometric evaluation and validation of the Serbian version of "Reading the Mind in the Eyes" test

"Reading the Mind in the Eyes" test (RMET) is one of the most popular and widely used measures of individual differences in Theory of Mind (ToM) capabilities. Despite demonstrating good validity in differentiating various clinical groups exhibiting ToM deficits from unimpaired controls, previous studies raised the question of the RMET's homogeneity, latent structure, and reliability. The aim of this study is to provide evidence on psychometric properties, latent structure, and validity of the newly adapted Serbian version of the RMET. In total, 260 participants (61.9% females) took part in the study. The sample consisted of both unimpaired controls (76.5%), and a clinical group of participants that are believed to demonstrate ToM deficits (23.5%), namely, persons diagnosed with schizophrenia and bipolar disorder (54.1% females). RMET has demonstrated fair psychometric properties (KMO=.723; alpha=.747; H1=.076; H5=.465), successfully differentiating between clinical group and control [F (1,254)=26.175, p lt . 001, eta(2)(p) =.093], while typical gender differences in performance were found only in control group. Tests of several models based on the previous literature revealed that the affect-specific factors underlying performance on RMET demonstrate poor fit. The best fitting model obtained included reduced scale with a single-factor underlying the test's performance (TLI=.953, CFI=.958, RMSEA=.020). Based on the fit parameters we propose 18-item short-form of the Serbian version of RMET (KMO=.797; alpha=.728; H1=.129; H5=.677) for economic, reliable and valid measurement of ToM abilities

SYSTEM APPROACH TO THE ANALYSIS OF COPPER CONCENTRATE PRODUCTION

In this paper, the production of copper flotation concentrate in the copper mineral processing plant „Veliki Krivelj“ (RTB Bor) was analysed. The correlation between the input parameters (copper content in the feed, consumption of lime, consumption of frother, collector consumption in the rough flotation stage, collector consumption in the scavenger stage and the pulp density in the rough flotation stage) and output parameters (copper content and recovery in the final concentrate) is accomplished by a systemic approach. The data for analysis were obtained in the time period November 2009 – February 2010 of the plant operation. Data were collected on a daily basis for all three shifts. For the analysis of obtained data, the techniques of linear and nonlinear statistical analysis were applied. Accordingly, the starting data were used to develop optimization model, which could be useful for the further analysis of the influence of input parameters on the final outputs – i.e. final concentrate grade and recovery

Effect of pretreatment with omega-3 polyunsaturated fatty acids (PUFAs) on hematological parameters and platelets aggregation in patients during elective coronary artery bypass grafting

Bacground/Aim. Using omega-3 polyunsaturated fatty acids (PUFAs) in coronary artery bypass graft surgery (CABG) could provide protection against ischemicreperfusion damage, prevention of postoperative arrhythmia and attenuation of inflammatory response. However, omega-3 PUFAs inhibit cyclooxygenase (and thus decrease the synthesis of thromboxane A2 from arachidonic acid in platelets), which leads to decreased platelet aggregation. In cardiac surgery it is necessary to achieve a balance between inhibition and full platelets function. It is as well as important to closely follow hematological parameters, impaired by CABG itself. Therefore, the aim of the study was to establish the effects of pretreatment with omega- PUFAs on hematological parameters and plateletes aggregation in patients with elective CABG. Methods. This prospective, randomized, placebo-controlled, single-center trial was performed on parallel groups. The patients (n = 40) undergoing elective CABG were randomized receiving preoperative intravenous omega-3 PUFAs (Omegaven® 10%) infusion (the PUFAs group) or the same volume of 0.9% saline solution infusion (the control group). Infusion was given a day before surgery and repeated four hours before starting extracorporeal circulation (CPB) via the peripheral vein at single doses of 100 mL (25 mL/h). Platelet function analysis was performed using multiple electrode aggregometry (MEA, multiplate-analyzer) before starting CPB and 2 h postoperatively for the patients of both groups. Results. There were no clinically relevant differences in baseline characteristics between the groups. Hematological parameters were not significantly different between the groups pre-, intra- and postoperatively. During the first 24 h after surgery, the loss of blood was similar in the PUFAs and the control group (680 ± 274 mL and 608 ± 210 mL, respectively; p = 0.356). Postoperatively, platelet aggregation was not significantly different between the PUFAs and the control group in adenosine diphosphate (ADP) test (39 ± 11 and 42 ± 15, respectively; p = 0.701), arachidonic acid (ASPI) test (64 ± 24 and 70 ± 27, respectively; p = 0.525) and trombin receptor-activating peptide (TRAP) test (68 ± 25 and 75 ± 26, respectively; p = 0.396), while their aggregation in collagen (COL) test was statistically significantly lower in the PUFAs related to the control group (32 ± 15 and 47 ± 20, respectively; p = 0.009). Conclusion. Acute pretreatment with omega-3 PUFAs insignificantly affected the activity of platelets and did not influence postoperative blood loss
