162 urine samples were collected from UTIs during October to December 2017 at Saladin General Hospital. E. coli was 38.9% of the collected samples. Women are more vulnerable to infection. The resistance percentage to Chloramphenicol, Ofloxacin, Ceftriaxone and Imipenem were 17% to 100%. The root exudates were prepared by using hydroponics with different periods: (7, 10 and 14 days). Onion (Allium cepa L.) root exudates have not any effect on the E. coli through the periods while root exudates of garlic (Allium sativum L.) gave the highest inhibitory effect at the period of 10 and 14 days. The virulence factors of E. coli were screened for the presence of hlyA through PCR and showed that all the resistant isolates could produce beta-hemolysis.
This study investigates the possibility of removing phenols and chemical oxygen demand (COD) from petroleum wastewater (refinery wastewater) using an electrocoagulation (EC) reactor supplied with aluminium electrodes. The influence of current density (CD) (4 to 12 mA/cm2), distance between electrodes (DBE) (20 to 40 mm), and treatment time (T) (up to 120 min) was investigated by carrying out several sets of batch flow experiments. The concentrations of COD and phenols were measured using the Hach-Lang spectrophotometer and standard cuvette tests (LCK 514, LCK 314, or APC 400 for COD, and LCK 346 or LCK 345 for phenols (according to the residual concentration). The results of the present study confirmed the ability of the electrocoagulation method to reduce the concentrations of both phenols and COD in petroleum wastewater within a relatively short treatment time. It has been found that the best removal efficiency of COD and phenols were 80% and 58%, respectively. The best removal efficiency was attended, after 100 min of electrolysing, at CD of 8 mA/cm2 and DBE of 20 mm.
Preserving the temperature of the indoor environment within the acceptable limits during the cold weather using a minimal amount of energy consumption is an important factor in the modern housing systems and green buildings. Therefore, this study aims to provide eco-friendly insulation material (organic material). The utlised organic material in this study was Lignocellusic Biomass (it is also known as Poaceae common reed, and Phragmites australis) and straw. The insulation efficiency of this organic matter was evaluated via testing its performance under controlled conditions. The experimental work included three types of insulation, namely organic insulation (straw and reeds), industrial insulation material (fiberglass), and bricks (without insulation). The insulation level was monitored using an infrared camera. The thermal profile was created for each insulation scenario. The results showed that the efficiency of the organic insulation was similar to the fiberglass; only a 0.84% difference was noticed between the industrial and the organic insulation materials in terms of efficiency, which proves that the Lignocellusic Biomass is a potential eco-friendly alternative for the industrial insulation materials.
A panel of 42 samples of fungal isolates from the ear canal was collected from Salahadin General Hospital in Tikrit city, Iraq. The results showed that only 9 isolates were Candida auris. The root exudates of Trigonella foenum-graecum L. seeds were used for 15 and 25 days, and the exudates were better when used for 25 days of compression of the inhibitory effect of cold aqueous extract. Antifungal susceptibility of candida isolated against 6 antibiotics the Candida isolates showed high resistance to the Clotrimazole, ketoconazole, fluconazole, and lionized as the resistance ratio are 100,100, 77.7, and 88.8% respectively. The ITS region was discovered using a PCR method in Candida isolates ITS segments that encode genotyping of Candida isolates were amplified under optimal circumstances. and the primers were amplified by 700bp.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
