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

Influence of inorganic consistuents on photocatalytic degradation of ibuprofen

Non-steroidal anti-inflammatory pollutants such as ibuprofen are continuously introduced in water media through various environmental routes. Due to their variability in physico-chemical properties, characteristics of sludge used in secondary treatment and other features, pharmaceutical residues are partially removed in conventional wastewater treatment plants. The effect of inorganic constituent (nitrates) present in real aquatic matrices was examined to assess the overall efficacy of the photocatalytic removal of ibuprofen by nanostructured mixture ZnO/SnO2

PREDICTION OF THE COPPER PRODUCTION IN THE FRAMEWORK OF ELECTRICAL ENERGY CONSUMPTION USING ARTIFICIAL NEURAL NETWORK

The metallurgical process of the copper production is a very complex process and requires the consumption of electrical energy in large quantities. One of the challenges of today is to reduce the use of electrical energy by increasing the energy efficiency of the system. This challenge can be solved by developing energy management in mining companies. In order to approach the development of energy management, it is necessary to create models for predicting the volume of copper production by investigating electricity consumption in the main production stages. In this paper, the consumption of electricity required in the process of copper production is analyzed on the example of a local mining company. Data on electricity consumption were collected for a period longer than one year and the parameters were divided according to the main phases of the metallurgical process. Two models for predicting copper production using artificial neural network were created and the most influential parameters were identified. The significance of the models is reflected in the efficient forecasting of the copper production and therefore the demand for electrical energy. Another advantage of the models is the increased possibility for rationalization of electricity consumption on the basis of the influential parameters. The models are recognized as flexible and can find their application in related companies

Hybrid critic-topsis model for prioritizing digitally developed countries in the light of energy indicators

Digital progress of the society is associated with trends in energetic sector. The top ten digitally developed European countries, according to the most recent ICT development index report in 2017, were chosen as testing countries to conduct a deeper investigation on the issue of energy production and consumption in the digital era. Data on (1, 2) coal and oil-fired electricity generation, (3) share of GHG emissions from energy production, (4) final electricity consumption in industry, (5) final electricity consumption in households, and (6) energy intensity were included in the initial database. For determining criteria weights and final ranking of alternatives, a hybrid CRITIC-TOPSIS MCDM model was utilized. The CRITIC approach was used to calculate objective weights of criteria by employing standard deviation to measure the contrast strength of each criterion. The findings highlight the dominance of three criteria in comparison to others: energy intensity (wei = 0.200), share of GHG emissions in total energy production (weGHG = 0.198), and ultimate energy consumption in households (wfch = 0.194). The TOPSIS approach was used to complete the final ranking. Switzerland, Luxembourg, and Sweden were ranked first, second, and third, respectively, in terms of advanced digitalization performance and awareness of the need of providing green energy for economic activity

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

Leachate quality assessment of protected water bodies in Serbia and Croatia

Modern agricultural production can not be imagined without the use of pesticides and, if their use is improper, it could lead to continuous introduction of pesticide residues to different environmental media. Water pollution which originates from agricultural activities is a common problem in both observed countries, Serbia and Croatia. The paper provides evaluation of leachate water quality of protected water bodies, Tompojevački ritovi, Croatia, and Lake Zobnatica, Serbia, with the results of detected pesticide residues and other relevant organic micropollutants

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
