    Lifetime measurements of low-lying excited states in the semimagic ( N = 50 ) nucleus 95Rh have been performed by means of the fast-timing technique. The experiment was carried out using γ -ray detector arrays consisting of LaBr3(Ce) scintillators and germanium detectors integrated into the DESPEC experimental setup commissioned for the Facility for Antiproton and Ion Research (FAIR) Phase-0, Darmstadt, Germany. The excited states in 95Rh were populated primarily via the β decays of 95Pd nuclei, produced in the projectile fragmentation of a 850 MeV/nucleon 124Xe beam impinging on a 4 g / cm2 9Be target. The deduced electromagnetic E2 transition strengths for the γ -ray cascade within the multiplet structure depopulating from the isomeric Iπ = 21 / 2+ state are found to exhibit strong deviations from predictions of standard shell model calculations which feature approximately conserved seniority symmetry. In particular, the observation of a strongly suppressed E2 strength for the 13 / 2+ → 9 / 2+ ground state transition cannot be explained by calculations employing standard interactions. This remarkable result may require revision of the nucleon-nucleon interactions employed in state-of-the-art theoretical model calculations, and might also point to the need for including three-body forces in the Hamiltonian

The aim of this study was to investigate possible association between incidence in relation to glioma and certain blood groups. Methods. The case-control study included 100 pathologically confirmed cases of glioma at the Clinical centar of Kragujevac, Serbia, between 2014 and 2015, and 200 age- and sex-matched controls without malignant diseases in personal and family history at the same institution. After signing the informed consent, all patients filled out an epidemiological questionnaire. Results. In the analysis comparing the glioma patients with the control group, a significant association (p < 0.0005) was observed in relation to the blood group AB. Furthermore, it was not observed a significant association in relation to the blood group A (p = 0.070), blood group B (p = 0.256), blood group O (p = 0.768) among the compared groups. Also, in the analysis comparing glioma patients with the control group, a significant association was observed in relation to the years spent

    Animation Content in Frame Analysis

    No full text
    Animation frame content is analyzed in this paper. The animation found in frame/video content is usually characterized by specific color distribution and texture. The existence of animation within a frame can be described by carefully selected features. We analyzed both fully and partially animated frames. Here, we present our initial results related to automatic animation interpretation using different types of video sequences

    © 2017, University of Kragujevac, Faculty of Science. All rights reserved. Stroke is one of leading causes of death worldwide. Different frequency of stroke occurence is observed in days of the week and months in the year, and incidence of stroke has irregular time pattern. We analyzed 516 patients who had acute stroke and were treated in Clinic of Neurology, Clinical Center Kragujevac from January 1, 2013 to January 1, 2014, mean age 72,11 ± 11,52. Statistical analysis is conducted out using the SPSS software version 20.0. We used descriptive statistic, student T-test, chi-square or Fisher exact test. Friday is day we found the most IS and all stroke types occurences, and Wednesday is day we found the most IS in men. We found the most strokes in women younger than 65 years on Wednesday, but in women older than 65 years on Friday. Monday is day with the most admissions to hospital for patients wiThis, and we observed that there is average delay in the refering to the doctor for 1.80 ± 1.44 days. Friday is the day with the most ICH symptom beginings and the most admissions to the hospital, and Saturday is the day with the least symptom beginings and admissions to the hospital in the case of IS and ICH. The most IS occured in winter (in Decembar), and the least in summer (in August). The most ICH occured in May, and the least in July and October. We confirmed that there is a significant weekly variability in the IS symptom onset day
