Properties of some Late Season Plum Hybrids from Fruit Research Institute Čačak

Since 1979 to 2012 fifteen plum cultivars were named and released in Fruit Research Institute, Čačak. Some of these cultivars, such as Čačanska Lepotica, Čačanska Rodna and Čačanska Najbolja are grown in most important plum growing countries in Europe. Also, these cultivars are used as parent cultivars in many plum breeding programs. In addition to the cultivars, large number of promising hybrids are created in Fruit Research Institute, Čačak and some of them, in this moment, are candidates for new cultivars. Therefore, in 2014 and 2015, we investigated the most important properties of four promising late season hybrids and standard cultivar ‘Stanley’. All four hybrids were harvested since beginning of September (34/41/87) until the beginning of the third decade of September (10/23/87). The earliest flowering time was recorded in hybrid 34/41/87 and the latest in standard cultivar ‘Stanley’. Hybrids 10/23/87 and 26/54/87 generally had the highest fruit weight and all three fruit dimensions. Also these hybrids had the highest content of total sugars and sucrose and highest pH value, but poorest total acids content. The highest content of invert sugars and total acids was recorded in hybrid 22/17/87. This hybrid also, had the highest yield per tree and per hectare while the hybrid 34/41/87 had the lowest these values. Standard cultivar ‘Stanley’ had the largest stone weight and the highest amount of soluble solids

Effect of vacuum and modified atmosphere packaging on microbiological properties of cold-smoked trout

Because of the importance of different packaging methods for the extension of fish shelf life, as a highly perishable food, the aim of the present study was to examine the effect of vacuum and modified atmosphere packaging on the total Enterobacteriaceae and lactic acid bacteria counts of cold-smoked Salmon trout (Oncorhynchus mykiss) stored at 3 degrees C during six weeks. Trout fillets were vacuumed packaged (VP) or packaged in one of two different modified atmospheres, with gas ratio of 50% CO2/50%N-2 (MAP1) and 90% CO2/10%N-2 (MAP2) and analysed on days 0, 7, 14, 21, 28, 35 and 42. Both the total Enterobacteriaceae and total lactic acid bacteria counts increased in the trout fillets in all packaging types during storage. A significantly lower total Enterobacteriaceae count was determined in the MAP fish compared to the VP fish, with the weakest growth rate and lowest numbers attained in MAP2 fillets. The lactic acid bacteria count was higher in trout packaged in MAP compared to VP, with the highest number in the MAP with 90% CO2 (MAP2)

Assessment of soil erosion rates in Southeastern Serbia using nuclear techniques

Erozija zemljišta vodom predstavlja vaţan problem zaštite ţivotne sredine u Srbiji. Posledica erozije je degradacija zemljišnih resursa, smanjenje plodnosti zemljišta i redukcija poljoprivredne proizvodnje. Najveši intenzitet erozije uoţen je na obradivom zemljištu na strmim padinama. Pretvaranje pašnjaka u obradivo zemljište uticalo je na povešanje prostora zahvašenih procesom erozije. U ovom radu prikazani su preli-minarni rezultati projekta tehniţke saradnje sa MeŤunarodnom agencijom za atomsku energiju ̳Jaţanje kapaciteta za procenu intenziteta erozije zemljišta koriššenjem nuklearnih tehnika u cilju podrške odrţivom upravljanju zemljištem‘ (SRB5003) ţiji je cilj procena intenziteta erozije zemljišta 137Cs-metodom. Istraţivanja sprovedena u basenima Pţinje i Juţne Morave ukazala su na intenzivnu eroziju na ovom prostoru. Istraţivanja še biti nastavljena na nekoliko drugih lokacija, a rezultati še biti upotrebljeni za podršku nacionalnim programima konzervacije zemljišta.Soil erosion by water presents an important environmental problem in Serbia resulting in degradation of the soil resources, reducing soil fertility and agricultural production. The highest intensity of erosion was observed at cultivated land occupying steep slopes. The conversion of pastures to arable land enhances this problem. This study presents the preliminary results of Technical Cooperation Project of International Atomic Energy Agency ̳Strengthening the Capacities for Soil Erosion Assessment Using Nuclear Techniques to Support Implementation of Sustainable Land Management Practices‘(SRB5003) aimed at estimation of soil erosion rates using the 137Cs-method. The investigation of Pčinja and South Morava River Basins in southeastern Serbia revealed intensive erosion in the area. The investigation will continue at several other sites and the results will be used to support national soil conservation policy.Proceedings: [http://vinar.vin.bg.ac.rs/handle/123456789/8681]XXX симпозијум ДЗЗСЦГ (Друштва за заштиту од зрачења Србије и Црне Горе), 2- 4. октобар 2019. године, Дивчибаре, Србиј

Search for MSSM Higgs bosons decaying to μ+μ− in proton-proton collisions at s=13TeV

A search is performed for neutral non-standard-model Higgs bosons decaying to two muons in the context of the minimal supersymmetric standard model (MSSM). Proton-proton collision data recorded by the CMS experiment at the CERN Large Hadron Collider at a center-of-mass energy of 13TeVwere used, corresponding to an integrated luminosity of 35.9fb-1. The search is sensitive to neutral Higgs bosons produced via the gluon fusion process or in association with a bbquark pair. No significant deviations from the standard model expectation are observed. Upper limits at 95% confidence level are set in the context of the mmod+hand phenomenological MSSM scenarios on the parameter tanβas a function of the mass of the pseudoscalar Aboson, in the range from 130 to 600GeV. The results are also used to set a model-independent limit on the product of the branching fraction for the decay into a muon pair and the cross section for the production of a scalar neutral boson, either via gluon fusion, or in association with bquarks, in the mass range from 130 to 1000GeV

Measurement of quark- and gluon-like jet fractions using jet charge in PbPb and pp collisions at 5.02 TeV

The momentum-weighted sum of the electric charges of particles inside a jet, known as jet charge, is sensitive to the electric charge of the particle initiating the parton shower. This paper presents jet charge distributions in s NN $$\sqrt{s_{\mathrm{NN}}}$$ = 5.02 TeV lead-lead (PbPb) and proton-proton (pp) collisions recorded with the CMS detector at the LHC. These data correspond to integrated luminosities of 404 μb −1 and 27.4 pb −1 for PbPb and pp collisions, respectively. Leveraging the sensitivity of the jet charge to fundamental differences in the electric charges of quarks and gluons, the jet charge distributions from simulated events are used as templates to extract the quark- and gluon-like jet fractions from data. The modification of these jet fractions is examined by comparing pp and PbPb data as a function of the overlap of the colliding Pb nuclei (centrality). This measurement tests the color charge dependence of jet energy loss due to interactions with the quark-gluon plasma. No significant modification between different centrality classes and with respect to pp results is observed in the extracted quark- and gluon-like jet fractions.CMS Collaboration (ukupan broj autora: 2301

Study of central exclusive pi+pi- production in proton-proton collisions at √s=5.02 and 13TeV

Central exclusive and semiexclusive production of pairs is measured with the CMS detector in proton-proton collisions at the LHC at center-of-mass energies of 5.02 and 13TeV. The theoretical description of these nonperturbative processes, which have not yet been measured in detail at the LHC, poses a significant challenge to models. The two pions are measured and identified in the CMS silicon tracker based on specific energy loss, whereas the absence of other particles is ensured by calorimeter information. The total and differential cross sections of exclusive and semiexclusive central production are measured as functions of invariant mass, transverse momentum, and rapidity of the system in the fiducial region defined as transverse momentum and pseudorapidity . The production cross sections for the four resonant channels , , , and are extracted using a simple model. These results represent the first measurement of this process at the LHC collision energies of 5.02 and 13TeV.CMS Collaboration (ukupan broj autora: 2326

Evaluation of grain yield and its components of some experimental, registered and commercial ZP maize (Zea mays L.) hybrids

The grain yield and its components of eighteen experimental, one registered and two commercial maize hybrids were examined in six different environments. The main objectives were to identify the best performing experimental and registered hybrids and to select appropriate hybrids for approving and commercialization. Based on the results, many decisions are made. Experimental hybrid Exp.15 is submitted for testing to the Variety Commission of the Ministry of Agriculture, Forestry and Water Management of the Republic of Serbia. This hybrid, as a high-yielding and a stable one, could enrich the assortment of registered mediumlate maize hybrids in Serbia. First year of its testing for the purpose of being registered is going to be 2020. Further, registered hybrid ZP 685 is suggested for commercialization as one of the best performing in present study. In addition, the goal of this study was also identification of the superior inbred lines for use in future breeding programs. Inbred lines L1 (BSSS) and L4 (Independent heterotic group) are chosen for crossing with an aim to create a new origin population - source for deriving new recombinant inbred lines. Cross L1 x L4 will be a part of maize breeding program at Maize Research Institute “Zemun Polje” in 2020. Lines L1 and L4 are also suggested for crossing with all others Lancaster lines from MRIZP (which are not parental components of tested hybrids) for deriving new experimental F1 hybrids. As well, Lancaster lines L5, L6 and L7 should be crossed between themselves for creating new origin populations for deriving new recombinant Lancaster inbred lines. Hybrid Sister 1 had very high and stable grain yield and as such it is the most cost effective for seed production

Attitudes of Primary School Teachers Toward Inclusive Education

Background: The aims of our study are related to examining the relevance of teachers' attitudes toward the implementation of inclusive education. In addition, its subject is related to the implications on inclusive education policies, limitations of the existing study along with the recommendations for our future research endeavors. Methods: The research is a cross-sectional study type. The sample included 64 primary school teachers in the lower grades of primary school (grades 1–4), selected by using simple random sampling, in three primary schools on the territory of Belgrade, Serbia in 2021 (26, 17, and 21 primary school teachers). The Questionnaire for Teachers, which was used as a research instrument, was taken from the Master's Thesis Studen Rajke, which was part of the project “Education for the Knowledge Society” at the Institute for Educational Research in Belgrade. Dependent variables measured in the study referred to the attitudes of primary school teachers toward inclusive education. Categorical variables are represented as frequencies and the Chi-square test was used to determine if a distribution of observed frequencies differed from the expected frequencies. Results: One in three teachers (32.8%) thought that inclusion was useful for children with disabilities (29.7%), of them thought that schools did not have the conditions for inclusive education, whereas one in four teachers (25.0%) believed that inclusion was not good. No statistically significant differences were found in the attitudes of professors, when observed in terms of their gender, age and length of service. Conclusion: Investing more resources and time in developing and implementing special education policies can promote successful inclusive education
