Nanofluid treatment of oil reservoirs is being developed to enhance oil recovery and increase residual trapping capacities of CO2 at the reservoir scale. Recent studies have demonstrated good potential for silica nanoparticles for enhanced oil recovery (EOR) at ambient conditions. Nanofluid composition and exposure time have shown significant effects on the efficiency of EOR. However, there is a serious lack of information regarding the influence of temperature on nanofluid performance; thus the effects of temperature, exposure time and particle size on wettability alteration of oil-wet calcite surface were comprehensively investigated; moreover, the stability of the nanofluids was examined. We found that nanofluid treatment is more efficie

The goal of this study is to perceive the immunological sex-differences in puberty age who have positive anti-Toxoplasma Immunoglobulin-G (IgG) specific antibodies. From the first of November 2012 till the end of April 2013, 303 blood samples were collected from students in both genders (150 males and 153 females) were divided into two age groups: group (A) which included subjects with age range (12-15) years old and group (B) which included subjects with age range (16-19) years old. Serum samples were tested for toxoplasmosis infections by using Enzyme Linked Immunosorbent Assay (ELISA) for anti-Toxoplasma IgG antibodies test. The results revealed that 107/303 (35.31%) of the studied subjects showed seropositive toxoplasmosis, 60 males

Background: Herbal medicine can be called one of the branches of medicine in various forms. Turmericcurcumin has proved its efficiencies a coloring, flavoring agent and has been traditionally used in medicine, exhibiting remarkable anti-inflammatory and antioxidant properties. The varied biological properties of curcumin and lack of toxicity even when administered at higher doses makes it attractive to explore its use in various disorders like diseases of skin. It is good potential agent for wound healing. Materials and methods: Sixty four new Zealand rabbits were used in this study ,they were divided into four groups,each group was subdivided as follows:Experimental groups(8 rabbits) right facial side of animals for essential oil applicati

This study were designed to make comparison between the influence alcoholic extract of Arctium lappa L. leaves and Pentoxifylline on treatment the adverse effect of gentamicin on DNA of sperms. Thirty five male rats were divided into 5 groups: the 1st group (T1) was made as negative control group, the 2nd group (T2) was given distilled water and gentamicin 5mg/kg (positive control group), the 3rd group (T3) was given a dose 600 mg/kg of Arctium lappa L and gentamicin, the 4th group (T4) was given dose 100mg/kg of pentoxifylline and gentamicin, the 5th group (T5) was given a dose 300mg/kg of Arctium lappa extract with dose 50mg/kg of pentoxifylline and gentamicin. The results of DNA damage% and agglutination % in T3, T4 and T5 appeared an

      The present study was designed to isolate the microbial community from oil-contaminated sites and other non-oil-contaminated sites which served as control samples in Kerbala city. In addition to test the effect of hydrocarbons on the growth of some types of bacteria. Bacterial genera and species were identified based on their growth on nutrient agar and blood agar as well as biochemical tests. According to the high bacterial growth rate on crude oil, 5 bacterial isolates were selected for further study. Growth of some identified bacteria in Minimal salt medium amended with hydrocarbon as the sole carbon source was investigated. Acinetobacter sp., Pseudomonas aeruginosa, Pseudomonas fluorescens, P

Results of the current study demonstratedthat out of eighty-three isolatesof Pseudomonas aeruginosa,only twenty-five isolateswere resistant to five different antibiotics (of different classes) that were consequentlyconsideredmultidrug resistant isolates.These isolates developed variable susceptibility toward Eucalyptuscamaldulensisleavesoil (ECO). GC-MS analysis of ECOrevealed that the aromatic oil eugenol is the major constituent.However, the most frequent MIC was 0.39 µg/ml, while the lowest frequent MIC was 3.125 µg/ml.Moreover, this oil at ½ MIC (0.195µg/ml) increased the gene expression of exoU. Itis concluded from the outcomes of the studythat ECOmay cause severe damagewhen used to treat infections caused by P. aeruginosa.
