Glasnik Srpskog Geografskog Dru?tva , 2008, DOI: 10.2298/gsgd0803087r
Abstract: Mt. Tara NP was nominated in 2004 within the UNESCO - ROSTE programme, for Man and the Biosphere (MAB) Reserve status in Serbia as transboundary 'Peace Park' status between Serbia and Bosnia & Herzegovina. Mt. Tara is one of the most important centres of Balkans and European ecosystems and species diversity. They represent a unique example of well preserved forests in south eastern Europe with numerous endemic and relict species of flora and fauna. In this floristic diversity of Mt Tara of the greatest interest is the Serbian (Pan i 's) spruce Picea omorika. Mt. Tara NP is characterized by specific geomorphologic, hydrologic, geologic, soil and climatic features. The geographical information system (GIS) that we have created has proved an excellent tool for the spatial planning strategy in assessment and conservation of all natural characteristics of Mt. Tara NP, and is helpful to Park management for sustainable use of landscape resources. GIS of Mt. Tara NP includes data on natural, artificial and management themes.
Influence of partial root drying on morpho-anatomical and physiological characteristics of tomato fruits: Lycopersicon esculentum l

Journal of Agricultural Sciences , 2004, DOI: 10.2298/jas0401013s
Abstract: Partial root drying (PRD) is a new irrigation and plant growing technique which improves water use efficiency without significant yield reduction. The aim of the presented thesis was to investigate the effect of this technique on the growth of vegetative and generative tomato organs, and especially fruits, its influence on the activity of enzyme cell wall peroxidase morpho-anatomical characteristics of flower and fruit pedicels, influence on fruits yield and quality and ions distribution in tomato organs. Tomato line L-4 (Lycopersicon esculentum L) was grown in commercial compost with the root system divided equally between two plastic pots. During the vegetative and generative phases of development, one half of the root system of PRD was maintained in a dry state, while the other half was optimally watered. After 10 days an inversion was made in such a way that previously wet side was exposed to drought and dried side was watered. Obtained results showed that as a consequence of PRD treatment the growth of whole plants was reduced with fruit size and yield of PRD plants being similar to control, as well as morpho-anatomical characteristics of pedicels, ions and lycopen contents although sugar content was higher in PRD than in control plants. These results suggest that with PRD technique we can halve the demand for irrigation water and increase the nutritional value of the tomato fruit.

Abstract: The key factor in preparation of the optimal training programme is a comprehensive research inthe field of the strength and the speed motory dimensions. Rationally chosen means and the modalities with an adequete intenisity and burden capacity enable even development of these motory capabilities.The main goal of the research, applying variables for determination of motory dimensions of the strength and the speed, was to spot the distinctions between trained and untrained twelve year sold boys. Two measurements were conducted, the initial one that lasted for 6 weeks and conducted before the implementation for the training model, and another, the final one,conducted after the implementation of the training model. Analysis of the values that are result of the application of the statistic method, shows that in both measurements better results were shown with the trained boys, whereas the training model had partly positive effect on the efficiency of the tests conducted to measure the strength and the speed at both groups.

Abstract: The first Serbian anatomist Jovan Andrejevi Joles was born in Novi Sad on October 6, 1833 to a priest father. The primary school and the first four grades of the grammar school he finished in Novi Sad, and the seventh and the eighth grades in Timisoara. After finishing grammar school, Andrejevi moved to Pest where he started medical studies in 1853. He continued the studies in Prague and Vienna where he received the diploma of a doctor of medicine. During the studies of medicine, this remarkably educated and talented man demonstrated great interest in science. In his research he came to new findings he published through the report of the Vienna Academy of Sciences in the paper titled 'On the Fine Structure of the Liver' (Ueber den feineren Bau der Leber), making his mentor, professor Ernest von Brücke, proud. Apart from the scientific work, young Andrejevi also translated literature from German and English. His interests also covered photography, art and aesthetics. He actively participated in the work of the United Serbian Youth, which brought him many problems with the ruling regime of the time. At a very early age, Andrejevi fell down with tuberculosis and had to stop his scientific work and move back to Novi Sad in 1861 where he began working as a physician. Apart from the medical practice, Andrejevi was still in the center of scientific, political, and cultural events. He continued regular correspondence with professor von Brücke who informed him on the success of his scientific results. Apart from a number of texts and critical writings, together with Jovan or evi , Andrejevi worked hard on the foundation of the Serbian National Theater in Novi Sad. During 1863, his illness aggravated and he died of tuberculosis on July 21, 1864. The memory of the first Serbian anatomist is kept by the Department of Anatomy of the Faculty of Medicine in Novi Sad where the documentation on his life and works is stored. The ground floor hall of the Faculty of Medicine holds the bust of Jovan Andrejevi .
Colour as an Element of the Creativity in Education of Design  [PDF]
Zoran Markovic
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.25015
Abstract: Education of Design is creativity based process. From Kansei Engineering to Emotional Design, there are several different approaches in involving feelings and emotions in designing process. Analysing all tools and techniques used by designers, colour has one of the biggest psychological impacts on the final users. Colour has the power not only to change the existing architectural language, but also to be a language on its own. Within architectural semiology, colour has a very important role. The paper presents the preliminary results of the research on cultural background and its influence on the psychological impact of the colour in design (architectural, interior, etc.). The research started in the beginning of 2012 and it has been conducted in Serbia, Botswana, Kenya (fully finalized), India, Slovenia, Brazil (ongoing), Singapore, South Africa and Malaysia (in the preparation stage), Japan, China, Russia, South Korea and Mexico (organization started). The Research objective is to describe, analyse and present importance of the emotional creativity in education, the current status of the role cultural background plays in colour choices in design, as well as to analyse psychological (personal) and social (group) impact and influence of colour. Moreover, the experiments planned are intended not only to outline contemporary cultural influence on colour preferences but also to revisit, revive and expand on the existing research in this field (e.g. [1] Kaya/Epps research at University of Georgia, USA, etc.) by adding the notion of multi-cultural background.
Maxwell-Proca Fields in Relativistic Astrophysical Compact Objects  [PDF]

Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.48A023
Abstract:

A general-relativistic model is formulated for hypothetical ultra-compact astrophysical objects composed of fluid infused with charges carrying a generalized massless Maxwell-Proca field. The chosen interior metric has the algebraic property that \"\"; the fluid consequently possesses a negative pressure which halts gravitational collapse and establishes hydrostatic equilibrium. For an object containing a global distribution of non-interacting Maxwell-Proca charges, it is shown that physical considerations define the relationship between the charge density and the metric function uniquely, corroborating an earlier finding (for an electrostatic distribution of charge) that the interior field must increase with radial distance and the exterior field necessarily follows an inverse-square law. For the case of a charged fluid envelope surrounding a core of uncharged fluid, numerous solutions are possible. Assuming the interior field to vary as rn and requiring its strength to increase with radial distance while the charge density decreases, the range of values for n is found to be 0 < n ≤ 1 (where n is not necessarily an integer) with n = 1 denoting the special case of a continuous distribution of charge. For both continuous and stratified charge distributions, the exterior field is found to decrease as 1/r2 regardless of the interior field’s dependence on

Abstract: Sweet corn differs from field corn in many important traits. So its breeding although includes some standard procedures demand application of techniques that are important for determining special traits, all because of the specificity of its usage. Application of molecular markers becomes almost a necessity for the breeding of sweet corn, especially because this is the type of maize in which still no definitive heterotic patterns have been determined. So getting to know genetic divergence of the sweet corn inbred lines is of great importance for its breeding. In this paper we analyzed genetic similarity of six sweet corn inbreds based on SSR markers. 40 SSR primers were used in DNA amplification. Results were compared and correlated with the data on specific combining ability, obtained by the diallel analysis. The results of SCA were in concurrence with genetic similarity. Values of rank correlation coefficient were negative, indicating that more similar inbred lines had smaller estimates of SCA, and lines that were less similar had higher estimates of SCA. Rank correlation coefficient between SCA and GS according to Dice coefficient was between -0,16 and -0,57*.
The purchasing power parity in emerging Europe: Empirical results based on two-break analysis

Abstract: The purpose of the paper is to evaluate the validity of purchasing power parity (PPP) for eight countries from the Emerging Europe: Hungary, Czech Republic, Poland, Romania, Lithuania, Latvia, Serbia and Turkey. Monthly data for euro and U.S. dollar based real exchange rate time series are considered covering the period: January, 2000 - August, 2011. Given significant changes in these economies in this sample it seems plausible to assume that real exchange time series are characterized by more than one time structural break. In order to endogenously determine the number and type of breaks while testing for the presence of unit roots we applied the Lee-Strazicich approach. For two euro based real exchange rate time series (in Hungary and Turkey) the unit root hypothesis has been rejected. For the U.S. dollar based real exchange rate time series in Poland, Romania and Turkey the presence of unit root has been rejected. To assess the adjustment dynamics of those real exchange rates that were detected to be stationary with two breaks, the impulse response function is calculated and half-life is estimated. Our overall conclusion is that the persistence of real exchange rate in Emerging Europe is still substantially high. The lack of strong empirical support for PPP suggests that careful policy actions are needed in this region to prevent serious exchange rate misalignment.

Medicinski Pregled , 2003, DOI: 10.2298/mpns0306232s
Abstract: Introduction Obesity is defined as an increase of body fat mass. Regional fat distribution, especially abdominal obesity, is a very important risk factor for cardiovascular and metabolic complications in obesity. The aim of this study was to investigate the relationship between some anthropometrics parameters and body fat mass in normal weight and obese subjects Material and methods The study group consisted of 60 obese and 60 normal-weight subjects of both sexes. All examinees underwent following anthropometrics measurements: body height, body weight, waist circumference hip circumference and sagittal abdominal diameter. We calculated values of body mass index (BMI), waist to hip ratio (WHR), waist to stature ratio (WSR) and sagittal abdominal diameter to height ratio (SAD/H). Body fat percent (FAT%) was measured using bioelectrical impedance analysis Results and discussion We have established that FAT% has the strongest correlation with BMI in all examined groups. Comparing with other body fat distribution parameters, FAT% had the best correlation with waist circumference and WHR. 13.33% of normal-weight women and 10% of normal-weight men presented with borderline increased body fat mass, whereas 6.67% of normal-weight women had increased values (normal-weight obesity). Normal-weight subjects had higher values of anthropometrics parameters comparing with normal-weight subjects with normal FAT%. Conclusion In order to achieve precise diagnosis of obesity it is necessary, apart from certain anthropometrics measurements, to establish the body fat mass, using some methods of body composition analysis. In order to identify subjects with higher risk for obesity complications, it is necessary to analyze the size of intraabdominal fat depots. We found that waist circumference, as a good predictor of specific fat distribution, also has a very good correlation with total body fat mass.

Abstract: Natural regeneration of beech in mixed stands of beech and fir was researched in the virgin forest Peru ica, e.g. the basic elements of stand structure with special reference to beech regeneration characteristics, and the regeneration process in the conditions of broken stand canopy. The analysis included the stand development stages in he virgin forest based on the elements of structure, as well as the silvigenetic phases on a transect 10×100 m. The characteristics of beech regeneration (abundance, height, crown size, length of apical and lateral shoots) were measured on the selected regeneration areas (initial regeneration gaps). The silvigenetic phases on the transect and the interdependence of beech regeneration characteristics were assessed based on regeneration characteristics, ways of occurrence and spatial distribution of the young growth.
