Cancer Incidence in a Population Living Near a Petrochemical Facility and Oil Refinery
(Collegium Antropologicum, Zagreb, 2011)
There is growing concern that pollution from petrochemical and oil refinery installations in Pancevo (Serbia) has increased the incidence of various diseases including cancer The aim of our study was to investigate cancer ...
Immobilization of glucoamylase via its carbohydrate moiety on macroporous poly(GMA-co-EGDMA)
(Elsevier, 2007)
We succeeded in the immobilization of 190 mg of periodate oxidized glucoamylase per gram of macroporous polymer. The covalently immobilized enzyme had a specific activity of 1100 U/g. The temperature and pH optimum as well ...
Investigation of interactions between surface water and petroleum-type pollutants
(Ecomed Publishers, Landsberg, 2005)
Background, Aims and Scope. In oil spill investigations, one of the most important steps is a proper choice of approaches that imply an investigation of samples taken from different sedimentary environments, samples of oil ...
Plasma assisted degradation of phenol solutions
(Vacuum, 2008)
Solutions of 2-chlorophenol, 4-chlorophenol and 2,6-dichlorophenol in bidistilled and water from the river Danube were treated in plasma reactor. In this reactor, based on coaxial dielectric barrier discharge at atmospheric ...
pi-Annulation reactions of 4-thiazolidinone enaminones in the synthesis of fused bi- and tri-cyclic compounds
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
The a-C position in 4-oxo thiazolidinones functions as one of the three possible nucleophilic sites in these molecules. We used the inherent reactivity of alpha-C of the exocyclic double bond (a so called push pull system) ...
Fatty Acid Profiles of Four Wild Mushrooms and Their Potential Benefits for Hypertension Treatment
(Mary Ann Liebert Inc, New Rochelle, 2011)
Mushrooms are useful in balancing human diet and treating different health problems. The main determinant of the fluidity of erythrocyte membranes and rheologic properties of blood is the lipid composition of the membrane, ...
Electrochemical behavior of silver-impregnated Al-pillared smectite in alkaline solution
(Springer, New York, 2010)
In order to enhance silver effectiveness for oxygen reduction reaction, pillared clay was used as a support for silver nanodispersion. Silver particles incorporation into pillared clay pores was attempted by impregnation/thermal ...
Characterization of a Silver Modified PVCAc Electrode and Its Application as a Ag(I)-Selective Potentiometric Sensor
(Wiley-Blackwell, Malden, 2011)
An all solid-state Ag(I) ion-selective electrode has been prepared by simply immersing a glassy carbon rod coated with PVCAc, which contained plasticizer and additive but no ionophore, into the AgNO3 solution. The response ...
Electrochemical instability of Pt nanoparticles probed by formic acid oxidation
(Elsevier, 2012)
A detrimental effect of CO on the stability of Pt nanoparticles, which is important for fuel cells technology, is demonstrated by the change in HCOOH kinetics on Pt nanoparticles caused by the presence of CO in the ...
Microstructural and basic mechanical characteristics of ZA27 alloy-based nanocomposites synthesized by mechanical milling and compocasting
(Sage Publishing, 2019)
Particulate nanocomposites with the base of ZA27 alloy were synthesized using an innovative route, which includes mechanical milling and compocasting. Scrap from the matrix alloy and ceramic nanoreinforcements were ...
