The paper deals with the problem of developing a method for calculating water hammer in distribution networks when a pump station is cut off, but without taking into consideration all characteristics of the pumps. Solving the problem starts with the general equations that described water hammer phenomena with linearized energy losses, applying the modified method of characteristics which is de ...

Quantitative properties of divergent genotypes of ryegrass (Lolium perenne L.). [Doctoral dissertation]
Лакић, Ж. 
Quantitative properties analyses of eight genetically divergent clone progeny of ryegrass (Lolium perenne L.) were conducted on a trial field and laboratories of the Agricultural Institute of Republic of Srpska in Banjaluka (Bosnia and Herzegovina). The analyses were performed on cambisol soil on alluvial substrate of Vrbas. During 2006-2008, the trials were conducted in order to analyze morph ...

Solonchaks of Vojvodina [Serbia] - characteristics and contemporary classification. [Doctoral dissertation]
Васин, Ј.Р. 
At representative Vojvodina sites labelled as solonchaks on soil map of Vojvodina 1:50000 (Nejgebauer et al., 1971) 25 soil profiles have been opened and soil samples have been taken from genetic horizons as well as ground water samples. Based on field observations and laboratory testing of morphological, water-physical, chemical and microbiological features, these soils were classified accord ...

Excessive amounts of soil boron may cause substantial yield losses in wheat. The most promising approach to solve problems associated with boron toxicity is the identification of boron tolerant wheat genotypes that can be exploited for the development of high-yielding tolerant cultivars. The variation among sixty divergent bread wheat (Triticum aestivum L.) genotypes in response to high boron ...

Microorganisms in soil under the maize crop and their potential for sulfonylurea herbicides degradation. [Doctoral dissertation]
Đurić, S. 
The objectives of this study were to assess the impact of sulfonylurea-based herbicides and their concentration on the number of soil microorganisms and soil enzyme activity under maize crop under field conditions, to determine their potential of these microorganisms for decompostion of nicosulfuron and foramsulfuron in laboratory conditions, and to isolate and determine strains capable of usi ...

Latković, D. 
The purpose of the study was to investigate the content and uptake of NPK nutrients by six corn inbred lines belonging to different FAO maturity groups, depending from nitrogen fertilization (control - without mineral fertilizer; 40 kg N/ha; 80 kg N/ha and 120 kg N/ha). At the same time the content of NO3-N in the soil was followed across the depth of the soil profile from 0 to 120 cm in the s ...

Nitrogen previous crop fertilization and Co and Mo application effect on soybean yield and grain characteristics. Doctoral dissertation
Dozet, G. 
This thesis covers research results of soybean fields in 2006, 2007 and 2008. The objective was to determine the effect of soybean seed inoculation with microbiological fertilizer and seed treatment with cobalt and molybdenum, as well as the effect of previous crop fertilization with different doses of nitrogen on yield and characteristics of soybean grain. Grain yield depended on previous cro ...

Current state and possibilities [for] tourism development [in] Middle Banat [Serbia] in the context of sustainable development. [Doctoral dissertation]
Мркша, М.М. 
Middle Banat area is a very interesting history, fertile land, characteristic relief, multi-ethnic structure of the population and sometimes a very developed economy. All these facts indicate that in this region there are good natural and social basis for the development of tourism but is still not used in a way. Therefore, it is necessary to conduct analysis of the Middle Banat, identify the ...

Nutrition profile, antioxidative potential and sensory quality of bread supplemented with sugar beet molasses. Doctoral dissertation
Filipčev, B. 
Osmotical dehydration in sugar beet molasses as hypertonic medium was used to treat apples, plums, carrots and red cabbage. Following the treatment, the fruits/vegetables were dried and ground. The study was aimed at determining the quality parameters of bread supplemented with the following ingredients: the freshly treated fruits/vegetables (at 10% and 30% level, flour basis), the powders der ...

Influence of fat phase composition of margarine on physical characteristics and quality of puff pastry. Doctoral dissertation
Šoronja-Simović, D. 
The possibility of application of low-trans margarine in the puff pastry production was investigated in this thesis. The base dough formula, which ensures the optimal dough handling during the laminating, has been defined in the first phase of the experimental work. By analysing the impact of the fat phase composition of puff pastry margarine on pastry quality, it has been revealed that the qu ...
