Analytical model for the determination of bending properties of glass-epoxy composites / Primena analitičkog modela za određivanje savojnih svojstava staklo-epoksi kompozitnog materijala
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2005)
Mechanical properties of composite materials are conditioned by their structure and depend from the characteristic of structural components. In this paper the analytical model has been shown with which the bending properties ...
Possibility of triticale degradation using ultrasound / Mogućnost primene ultrazvuka za razgradnju tritikalea
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2009)
Influence of ultrasound on triticale was investigated. Triticale is a cereal characterized with high yields per hectare and its ability to grow on marginal lands. It's most frequently used as animal feed supplement or in ...
Numeric analysis of tension condition of pressure vessel for the storage of beer / Numerička analiza naponskog stanja posude pod pritiskom za skladištenje piva
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2005)
Pressure vessels during the usage are exposed under very bad working conditions which make very high tension. In this work the calculation of all the elements of vertical cylindrical pressure vessel for the storage of beer ...
Through thickness optimal design of glass-epoxy composite pressure vessel / Optimizacija strukture laminarnog kompozitnog materijala po debljini zida posude pod pritiskom
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2005)
Mechanical loading of pressure vessels mainly comes from pressure (inner and outer) under which is vessel subjected. Tension which appears changes according to the thickness of the wall. Thanks to the its specific structure, ...
Microwaves in organic chemistry and organic chemical technology / Primena mikrotalasne tehnike u organskoj hemiji i organskoj hemijskoj tehnologiji
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2005)
The usual way of applying heat to a chemical reaction is the use of a Bunsen burner, an oil or some other type of bath, or an electric heater. In inorganic chemistry, microwave technology has been used since the late 1970s, ...
The effect of fermentation medium composition on lipase production by yeast Candida utilis / Uticaj sastava fermentacione podloge na prinos produkovanih lipaza pomoću kvasca Candida utilis
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2007)
In this work lipolytic activity of various microorganisms isolated from spoiled soybean oil was studied. Wild yeast strain identified as Candida utilis was chosen for the producing microorganism based on the activity shown ...
Methanolysis of sunflower oil using alumina/silica supported potassium oxide (K2O) as a heterogeneous catalyst / Metanoliza suncokretovog ulja katalizovana kalijum oksidom (K2O) na alumosilikatnom nosaču
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2009)
Biodiesel, the most promising alternative to diesel fuel, is renewable, biodegradable, environmentally friendly and can be used in existing engines. Certain disadvantages of conventional processes of biodiesel, i.e. fatty ...
