Microorganisms growing in a biofilm are correlating with chronic human infections and are highly resistant to immune system, antimicrobial agents and difficult to remove from the infected host. There are different methods to determine biofilm production such as Microtitre Plate (MtP) method , Congo Red Agar method (CRA) and Tube Method (TA) method .This study was carried out from December 2015 to september 2016, 580 specimens were obtained from patients at different hospitals in Erbil city/ Iraq. Staphylococcus aureus clinical isolates were identified phenotypically by different biochemical and molecular tests. One hundred isolates were found to be Staphylococcus aureus. MtP, CRA and TA tested Biofilm determination. This study was aimed to compare three methods of biofilm production. The results found that the accuracy and specificity of MtP was 100%, while it was 87%, 75% and 91% ,81.25% for CRA and TA methods respectively . The MtP method was considered to be superior to CRA and TA methods, and this method was the better screening for biofilm formation than CRA and TA methods, so this method can be a reliable quantitative tool for detection of biofilm formation in clinical isolates of S. aureus

Journal of University of Anbar for Pure Science , volume:11 issue:2

It had been studied the effect of reinforcement by Nano Titanium Dioxide (nano-TiO2) powder, Nano Zinc Oxide (nano-ZnO) powder [both of them with grain size of (10-30)nm], and the hybrid (TiO2+ZnO) from the powder above (with 2wt.% concentration), on the mechanical properties and thermal conductivity for polymeric composites that it basis by epoxy resin which prepared by Hand Lay-up molding method. For prepared samples, it had been made compression strength, surface hardness and thermal conductivity tests in natural conditions (without immersion), and after the immersion in solution of diluted hydrochloric acid (HCl) with two normality (0.5N and 1N). Tests results showed that previous addition ceramic powders improved the mechanical properties for composite materials. The hybrid composite had higher compression strength, higher Elasticity strength and higher hardness, followed by (Ep+ZnO) composite. Also, the hybrid composite had less thermal conductivity coefficient (K).On the other hand, the composites immersion in diluted HCl solution led to affect their previous mechanical properties by negativity manner. The hybrid composite was the least affecting, and the acid expansion in composites led to oscillate the values of thermal conductivity coefficient. At the end of immersion time, the coefficient (K) dropped for hybrid composite more than two composites (Ep+TiO2) and (Ep+ZnO).

Journal of University of Anbar for Pure Science , volume:11 issue:2

In this work the effect of adding SiO2 powder on the hardness property for UPE was studied. Three groups of samples were prepared (UPE/(SiO2-Micro)), (UPE/(Nano-SiO2) and (UPE/(Micro+Nano)SiO2) with weight fraction of additives (%2، %4، %6، %8). The surface hardness for all samples was measured before and after irradiation with Ultraviolet at time interval (10) hours. The experimental results showed that the surface hardness of all samples increases with increasing the weight fraction of SiO2 in the composite in natural conditions, and that the nano samples has higher hardness than other samples. After UV irradiation, the hardness values also increase with increasing the weight fraction of SiO2 in the composite for all samples, and their value is higher than in normal conditions.
