Concentrations of Cu, Zn, Cd and Pb in urban soils in parks and green areas of Belgrade / Zagađenje metalima urbanog zemljišta u parkovima i zelenim površinama u Beogradu
(Association of the Chemical Engineers of Serbia, 2006)
Several metals in urban soils of Belgrade were extracted by two methods which respectively give estimates of the available and "quasi total" contents. Soil samples were collected from six parks and three green areas within ...
Fitness-for-purpose assessment of repaired feedwater heater / Ocena podobnosti za upotrebu zagrejača napojne vode posle popravke
(Society for Structural Integrity and Life, Institute for Material Testing, 2006)
The leakage of tube-tubesheet joint of feedwater heater on the inlet required redesign and repair by additional tube welding. The original design took into account only the sealing, and subsequently after some period leakage ...
The adhesion of epoxy cataphoretic coating on phosphatized hot-dip galvanized steel / Adhezija epoksidne kataforetske prevlake na fosfatiranom pocinkovanom čeliku
(Association of Chemical Engineers of Serbia, 2006)
The influence of hot-dip galvanized steel surface pretreatment on the adhesion of epoxy cataphoretic coating was investigated. Phosphate coatings were deposited on hot-dip galvanized steel and the influence of fluoride ...
An investigation into the influence of hydrogel composition on swelling behavior and drug release from poly(acrylamide-co-itaconic acid) hydrogels in various media
(Taylor & Francis Ltd, Abingdon, 2006)
The hydrogels prepared by free radical copolymerization of acrylamide and itaconic acid were investigated with regard to their composition and crosslinking degree to find materials with satisfactory swelling and drug release ...
Using geothermal water for greenhouse heating
(Vinca Institute of Nuclear Sciences, 2006)
On construction with dimensions 15 x 5 x 2 m, conditions of temperature transmission and vegetables growth are examined. We have been cultivating pepper, cucumber, small cucumber, tomato, and lattice. Over ground heating ...
Cardiac tissue engineering: effects of bioreactor flow environment on tissue constructs
(Wiley, Hoboken, 2006)
The limited ability of cardiac muscle to regenerate after injury and the small number of organs available for transplantation motivate studies aimed at curative treatment options. Tissue engineering based on the integrated ...
Stress field analysis around optical fiber embedded in composite laminae under transverse loading / Analiza naponskog stanja u okolini optičkog vlakna ugrađenog u kompozitnu laminu pri transferzalnom opterećenju
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, 2006)
The influence of embedded optical fiber on stress state of transversally loaded composite laminae was analyzed in this paper. The optical fiber interaction with the host material (composite) has noticeable effect on the ...
Microencapsulation in the textile industry / Mikroinkapsulacije u tekstilnoj industriji
(Association of the Chemical Engineers of Serbia, 2006)
The application of microencapsulation techniques offers the possibility of producing novel products with many advantages compared to traditional textile products. The microcapsules can introduce important new qualities to ...
Damage detection in laminar thermoplastic composite materials by means of embedded optical fibers / Detektovanje oštećenja u laminarnim termoplastičnim kompozitnim materijalima korišćenjem ugrađenih optičkih vlakana
(Association of Chemical Engineers of Serbia, 2006)
This paper investigates the possibility of applying optical fibers as sensors for investigating low energy impact damage in laminar thermoplastic composite materials, in real time. Impact toughness testing by a Charpy ...
Bioethanol: State and perspectives / Bioetanol - stanje i perspektive
(Association of Chemical Engineers of Serbia, 2006)
