The effects of commercial fibres on frozen bread dough
JELENA FILIPOVI,NADA FILIPOVI,VLADIMIR FILIPOVI
Journal of the Serbian Chemical Society , 2010,
Abstract: The daily intake of dietary fibres in highly industrialized countries is at a low level and, therefore, adversely affecting human health. The objective of this research was to analyze the influence of different commercial fibres (originating from sugar beet pulp fibrex, and Jerusalem artichoke inulin HPX and GR) in yeast dough at a level of 5 %, on the rheological properties of dough and the quality of bread during frozen storage. Frozen dough characteristics were determined using a Brabender maturograph and test baking was followed according the AACC procedure. The dough was frozen at –18 °C and stored over a period of 60 days. The results concerning the dough (proving time and stability) and bread quality (volume and crumb quality) were statistically analyzed by multivariance Manova and discriminative analysis, which indicated that there was a significant difference between dough without fibres and dough with different fibres (fibrex, inulin HPX and GR). The discrimination coefficient points that the greatest influence of fibres on the final proof and proving stability is after 30 days (6.250) and after 0 days (6.158), respectively, but the greatest influence of fibres on bread volume and bread crumb quality (15.488 and 3.638, respectively) can be expected on non frozen dough, due to above mention their adverse the effect on gluten network.

FilipoviVladimir S.,?ur?i? Biljana Lj.,Ni?etin Milica R.,Plav?i? Dragana V.
Hemijska Industrija , 2012, DOI: 10.2298/hemind120130033f
Abstract: The effects of osmotic dehydration on mass transfer properties and microbiological profile were investigated in order to determine the usefulness of this technique as pre-treatment for further treatment of meat. Process was studied in two solutions (sugar beet molasses, and aqueous solution of sodium chloride and sucrose), at two temperatures (4 and 22°C) at atmospheric pressure. The most significant parameters of mass transfer were determined after 300 minutes of the dehydration. The water activity (aw) values of the processed meat were determined, as well as the change of the microbiological profile between the fresh and dehydrated meat. At the temperature of 22°C the sugar beet molasses proved to be most suitable as an osmotic solution, despite the greater viscosity.

Petrovi? Vladimir P.,Filipovi? Vojislav
Balcanica , 2009, DOI: 10.2298/balc0940023p
Abstract: The 2009 archaeological campaign at Ni evac, eastern Serbia, has provided important evidence for the urban growth of a Roman settlement, such as drains and a section of the Roman road traversing the settlement. Along with a sumptuous structure furnished with a wall heating system discovered in 2008, the latest excavation results provide clues as to the importance of the settlement which, containing all elements of Roman urban architecture, offers further corroboration to its presumed identification as the Roman station of Timacum Maius on the Lissus-Naissus-Ratiaria road.
Newly-discovered traces of the Roman Naissus-Ratiaria road and the problem of locating two Timacum stations
Petrovi? Vladimir P.,Filipovi? Vojislav
Balcanica , 2007, DOI: 10.2298/balc0738029p
Abstract: The goal of this paper is to reopen the question of and propose a solution to the as yet unresolved problem of the exact location of the Timacum stations on the Naissus-Ratiaria itinerary road. Based on plentiful material evidence it seeks to draw a more reliable picture of the Roman itinerary road and its newly-discovered traces. Also, it points to the possibility of a completely new interpretation of the itinerary sources relating to this issue. The method adopted here relies on the data contained in the Roman itineraries as well as on the archaeological and epigraphic evidence.
Locating the timacum maius station on the roman road lissus-naissus-ratiaria: New archaeological research
Petrovi? Vladimir P.,Filipovi? Vojislav
Balcanica , 2008, DOI: 10.2298/balc0839047p
Abstract: As the exact location of two Timacum stations remains an open issue, the results of the latest archaeological investigations in the environs of Svrljig, southeast Serbia, seem to offer some corroborative evidence for the hypothesis proposed in our previous contribution that this might be the location of Roman Timacum Maius. A small-scale trial excavation was undertaken on the Roman site at Kalnica in the Ni evac village area in July 2008. A trench 4 by 2m was opened in the zone of the site that had yielded plentiful fragments of building debris as well as small finds. A massive wall over 1m thick was found immediately beneath the surface. Built of bro-ken limestone and pebbles bound with lime mortar, it obviously was part of a larger structure. To the northeast of the wall was an area covered with fragmented roof tiles. The discovery of two ceramic tumuli embedded in the wall, indicating a wall-heating system so far unregistered on the representative Roman urban and settlement sites in Serbia, gives additional grounds to presume that this was a larger Roman settlement extending over an area of more than 5ha, possibly Timacum Maius, a station on the Roman road Lissus-Ratiaria-Naissus.
Influence of agroecological conditions on root yield of celeriac
FilipoviVladimir,Jev?ovi? Radosav
Journal of Agricultural Sciences , 2006, DOI: 10.2298/jas0601025f
Abstract: What we have in the present paper are the results of analysis on how the amount of precipitation, temperature, type of soil, and drip irrigation can affect celeriac root yield. The soil type had a considerable influence on yield. In both study years concerning two ways of growing - watering and dry cultivation, the celeriac root yield was higher on the chernozem soil type. The higher amount of precipitation and higher temperature during the period of vegetation resulted in higher root yield the first study year (both locality and dry cultivation). Compared with in dry cultivation, in both study years as well as both localities, drip irrigation had higher effects on celeriac root yield. .

Savi? Aleksandar,?ukilovi? Tijana,FilipoviVladimir
Yugoslav Journal of Operations Research , 2011, DOI: 10.2298/yjor1101093s
Abstract: This paper considers the two dimensional rectangular packing problem. The mathematical formulation is based on the optimization of a non-linear function with piecewise linear constraints with a small number of real variables. The presented method of m-M calculus finds all optimal solutions on small instances. Computational performance is good on smaller instances.

Srpski Arhiv za Celokupno Lekarstvo , 2012, DOI: 10.2298/sarh1202058i
Abstract: Introduction. Increasing energy expenditure through certain exercise is an important component of effective interventions to enhance initial weight loss and prevent weight regain. Objective. The purpose of this study was to determine the effect of a 16-week weight loss exercise programme on morpho-functional changes in female adults and to examine the programme effects on two subpopulations with different levels of obesity. Methods. Fifty-six middle-aged women were divided into 2 groups according to their body mass index (BMI): 25-29.9 kg/m2 - overweight (OW) and ≥30 kg/m2 - obese (OB). The exercise protocol included a walking technique based on hip rotation at horizontal plane at speeds close to the preferred transition speed (PTS). At the initiation of the study and after 16 weeks of the programme, anthropometric, morphological and cardiovascular parameters of all subjects were assessed. The main effects of Group (OW and OB) and Time and the interaction effect of Group by Time were tested by time repeated measures General Linear Model (mixed between-within subjects ANOVA). Results. Mean weight loss during the programme was 10.3 kg and 20.1 kg in OW and OB, respectively. The average fat mass (FM) loss was 9.4 kg in OW and 16.9 kg in OB. The Mixed ANOVA revealed a significant Group by Time interaction effects for waist circumference, body weight, body water, fat free mass, FM, %FM and BMI (p<0.05). Conclusion. The applied exercise protocol has proved as beneficial in the treatment of obesity, since it resulted in a significant weight loss and body composition changes. The reduction in body weight was achieved mainly on account of the loss of fat mass.
Influence of additive from sugar beet on white bread quality
Filipovi? Nada K.,Gyura Julianna F.,Filipovi? Jelena S.
Acta Periodica Technologica , 2004, DOI: 10.2298/apt0435025f
Abstract: The additive of acceptable sensory, physical and chemical and microbiological characteristics was made from cossettes. Great water binding capacity related to microcrystals of cellulose qualifies this additive as a desired one in bread making process. Bread was baked in the laboratory and patent flour was used. The additive with particles smaller than 95 (m was supplemented in the quantities of 2, 5 and 10%. The data related to the influence of the quantity of additive on white bread quality point that parallel to increasing the amount of the additive in the dough, yield of dough and bread were also increased. Negative effects are detected as volume depression and inferior bread crumb quality and altered crumb color. The decrease in bread quality is small if 2% of additive was applied, but significant with 5 and 10%. The bread freshness was highly graded 48 hours after baking due to the ability of the additive to retain water. On the whole, bread of superior quality supplemented by 5 and 10% of the additive from sugar beet fiber can be easily made by fortifying flour with gluten and by adding appropriate dough conditioner.

Glasnik ?umarskog Fakulteta , 2010, DOI: 10.2298/gsf1001125n
Abstract: The calculation of the influence of the underground water level on the habitat conditions of pedunculate oak in the lowland Ravni Srem is presented. The management method in these forests is greatly determined by moisture regime. Hydrogeological conditions are significant factors of moisture distribution in the soil during the vegetation period. In the river Sava alluvial deposits in Ravni Srem, the serried type of aquifer was formed, mostly of subartesian character, connected with river waters by hydraulic connection. The calculation of underground water regime was adapted to the conditions of two-layer porous environment in the river Sava alluvium, in order to define the oscillations of piezometric pressure in the lower aquifer and the level of underground waters in the upper, less porous layer.
