Histological and immunohistochemical evaluations of rat soft tissue response to bioceramical implants / Histološka i imunohistohemijska procena reakcije mekog tkiva pacova na biokeramičke implante
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2009)
The purpose of this study was to evaluate the tissue response induced by bioceramical materials (BCM) implanted in rat subcutaneous tissue. Thirty two rats were assigned to 6 groups, as following: control group i.e. not ...
A study of the photocatalytic degradation of methomyl by UV light
(Association of the Chemical Engineers of Serbia, 2009)
The photocatalytic degradation of insecticide methomyl in water, using TiO2 and ZnO (Merck), under UV (366 nm) was studied. The influence of the catalyst concentration and pH was investigated. The optimal concentration of ...
Damage detection of hybrid aramid/metal-PVB composite materials using optical fiber sensors
(Association of the Chemical Engineers of Serbia, 2009)
Embedding optical fiber sensors within laminar thermoplastic composite material results in forming a system known as 'smart structure'. These sensors present the information about the inner structure health during the ...
Determination of inorganic anions in papermaking waters by ion chromatography
(Journal of the Serbian Chemical Society, 2009)
A suppressed ion chromatography (IC) method for the determination of inorganic anions in process water from paperboard production was developed and validated. Common inorganic anions (Cl(-), NO(3)(-), PO(4)(3-) and SO(4)(2-)) ...
Local heat transfer coefficients during the evaporation of 1,1,1,2-tetrafluoroethane (R-134a) in a plate heat exchanger / Lokalni koeficijenti prelaza toplote pri isparavanju 1,1,1,2-tetrafluoretana (R-134a) u pločastom razmenjivaču toplote
(Serbian Chemical Society, Belgrade, 2009)
The evaporation heat transfer coefficient of the refrigerant R-134a in a vertical plate heat exchanger was investigated experimentally. The area of the plate was divided into several segments along the vertical axis. For ...
Supercritical carbon dioxide extraction of antioxidants from rosemary (Rosmarinus officinalis L.) and sage (Salvia officinalis L.) / Natkritična ekstrakcija antioksidanasa iz ruzmarina (Rosmarinus officinalis L.) i žalfije (Salvia officinalis L.)
(Serbian Chemical Society, Belgrade, 2009)
The aim of the present study was to isolate and characterize antioxidant extracts obtained from dried leaves of rosemary (Rosmarinus officinalis L.) and sage (Salvia officinalis L.), originating from the southern Balkan ...
Removal of mineral oil and wastewater pollutants using hard coal
(Association of Chemical Engineers of Serbia, 2009)
This study investigates the use of hard coal as an adsorbent for removal of mineral oil from wastewater. In order to determine the efficiency of hard coal as an adsorbent of mineral oil, process parameters such as sorption ...
Effect of non-stationary current regimes on the morphology of silver electrodeposits / Efekat nestacionarnih strujnih režima na morfologiju taloga srebra
(Serbian Chemical Society, Belgrade, 2009)
This work is concerned with the use of reverse current regimes in order to form small-grained and compact silver deposits during the electrorefining process. Several parameters were varied, i.e., i) anodic overpotential, ...
The bioethanol production with the thin stillage recirculation
(Association of the Chemical Engineers of Serbia, 2009)
In this paper, the bioethanol production with the thin stillage recirculation in mashing was investigated. The mashing was performed with recirculation of: 0, 10, 20 and 30% of the thin stillage. The thin stillage recirculation ...
The study of linear solvation energy relationship for the reactivity of carboxylic acids with diazodiphenylmethane in protic and aprotic solvents / Proučavanje reaktivnosti karboksilnih kiselina sa diazodifenilmetanom u aprotičnim i protičnim rastvaračima pomoću linearne korelacije solvatacionih energija
(Serbian Chemical Society, Belgrade, 2009)
Solvent effects on the reactivity of cycloalkenecarboxylic, cycloalkeneacetic, 2-substituted cyclohex-1-enecarboxylic, 2-substituted benzoic, 2-substituted cyclohex-1-eneacetic, 2-substituted phenylacetic, 2-phenylcycloh ...
