Catalytic wet air oxidation of aqueous phenol solution was studied in a pilot plant trickle bed reactor using copperoxide catalyst supported on alumina and silica. Catalysts were prepared by impregnating method. Effect of feed solutionpH (5.9, 7.3, and 9.2), gas flow rate (20%, 50%, 80%, and 100%), WHSV (1, 2, and 3 h-1), temperature (120°C, 140°C,and 160°C), oxygen partial pressure (6, 9, 12 bar), and initial phenol concentration (1, 2, and 4 g/l).Generally, theperformance of the catalysts was better when the pH of feed solution was increased. The catalysts deactivation is relatedto the dissolution of the metal oxides from the catalyst surface due to the acidic conditions. Phenol oxidation reactionwas strongly affected by WHSV,

تعد الحروب الصليبية الظاهرة الأبرز التي ميزت العصور الوسطى ، وقد مثلت مادة خصبة لأدبيات الباحثين الغربيين والمسلمين فتناولوا بالبحث والتحليل والاستنتاج أحداث حملاتها المتعددة ومن جوانب مختلفة، وذلك لما انطوت عليه من آثار وتحولات تاريخية كبيرة انعكست سلبا وايجابا على جانبي الصراع. لقد دأب مؤرخو الحروب الصليبية التقليدين على تسمية الحروب الصليبية بالحروب الدينية التي نشبت بحسب رأيهم لأسباب وغايات دينية ب

Leishmania are protozoan parasites belonging to the family Trypanosomatidae that cause high morbidity and mortality levels with a wide spectrum of clinical syndrome. This study aimed to investigate the effect of liposomal amphotericine B (AmBisome) drug on promastigote and axenic amastigote stages of Leishmania donovani isolate (MHOM/IQ/2005/MRU15)in comparison with pentostam SbV drug. Different concentrations of AmBisome and SbV drugs were investigated against Leishmania donovani promastigote and axenic amastigote. The ICR50R values of SbV and AmBisome drugs on promastigote were10.12 mg/ml and 2.21μg/ml, respectively, while they were 0.77μg/ml for axenic amastigote for both drugs. The present study concluded that axenic amastigote was

The aim of present study is to investigate the antagonistic activity of Spirogyra micropunctata against multidrug resistant human pathogens. The test organisms include 3 Gram negative bacteria such as Echerichia coli, Klebsiella pneumoniae, Salmonella typhi and 2 Gram positive bacteria such as Staphylococcus aureus and Staphylococcus epidermidis. The algal cell mass was extracted in 90% Methanol and 90% Ethanol and further concentrations of 0.5, 1, 3, 5, 10, 20 mg/ml were made for each extract. Antagonistic effect was tested by using agar well-diffusion method. Methanolic crude extract showed strong antibacterial activity against all tested bacteria, while ethanolic crude extract showed moderate activity. These findings suggest the possi

The objective of this paper is to improve the general quality of infrared images by proposes an algorithm relying upon strategy for infrared images (IR) enhancement. This algorithm was based on two methods: adaptive histogram equalization (AHE) and Contrast Limited Adaptive Histogram Equalization (CLAHE). The contribution of this paper is on how well contrast enhancement improvement procedures proposed for infrared images, and to propose a strategy that may be most appropriate for consolidation into commercial infrared imaging applications.
The database for this paper consists of night vision infrared images were taken by Zenmuse camera (FLIR Systems, Inc) attached on MATRIC100 drone in Karbala city. The experimental tests showed sign

ZnO nanostructures were synthesized by hydrothermal method at different temperatures and growth times. The effect of increasing the temperature on structural and optical properties of ZnO were analyzed and discussed. The prepared ZnO nanostructures were characterized by X-ray diffraction (XRD), UV–Vis. absorption spectroscopy (UV–Vis.), Photoluminescence (PL), and scanning electron microscopy (SEM). In this work, hexagonal crystal structure prepared ZnO nanostructures was observed using X-ray diffraction (XRD) and the average crystallite size equal 14.7 and 23.8 nm for samples synthesized at growth time 7 and 8 hours respectively. A nanotubes-shaped surface morphology was found using scanning electron microscopy (SEM). The optic

Cohesive soils present difficulties in construction projects because it usually contains expansive clay minerals. However, the engineering properties of cohesive soils can be stabilized by using various techniques. The research aims to elaborate on the influences of using hydrated lime on the consistency, compaction, and shear strength properties of clayey soil samples from Sulaimnai city, northern Iraq. The proportions of added hydrated lime are 0%, 2.5%, 5%, 7.5% and 10% to the natural soil sample. The results yielded considerable effects of hydrated lime on the engineering properties of the treated soil sample and enhancement its strength. The soil's liquid limit, plasticity index, and optimum moisture content were de

In this paper, compared eight methods for generating the initial value and the impact of these methods to estimate the parameter of a autoregressive model, as was the use of three of the most popular methods to estimate the model and the most commonly used by researchers MLL method, Barg method  and the least squares method and that using the method of simulation model  first order autoregressive through the design of a number of simulation experiments and the different sizes of the samples.

Abstract:

The researcher shed light on a diet in Iraq before 2003 became in this period. And how the ration card has a variety of vocabulary and cover the need of the population of commodities and have a key role in saving Iraq from a real crisis in the period of economic siege, especially in light of the State's direction to support the agricultural sector, which in that period able to fill half of the market needs of food the basic. As well as providing strategic storage at the Ministry of Commerce enough for six months But after the events of 2003 and the crises that hit the country and the unstable security situation began to rise voices calling for reform of the ration card system as a system that is a burden on the

      This study was conducted to evaluate the effects of Tharthar Arm on the composition and diversity of Rotifera in Tigris River. Six sampling sites were selected, two on Tharthar Arm and four along the Tigris River, one before the confluence as a control site and the others downstream of the confluence. Seventy-seven species of Rotifera were identified in Tigris, whereas, 60 in the arm. The results showed that low density of Rotifera in Tharthr Arm decreased the density in Tigris from 239812.4 upstream of the confluence to 223315.5 at immediate downstream of the confluence. It also declined the mean values of richness, evenness and Shannon diversity indices from 5.19, 0.69 and 2.14 bit/Ind., before the confluence to 3.97, 0.73 a

The synthesis of gold nanoparticles AuNPs was achievedby the reduction of sodium tetrachloroaurate (III) (NaAuCl4) with ceftriaxone sodium (CR) in aqueous solutionswithout the use of other reducing agent. The effect of reactants concentration, temperature and pH on the sizes and morphology of AuNPs were also studied. The synthesized AuNPs were characterized by UV- visible spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM), and atomic force microscope (AFM) analysis. Conjugation of antibiotic with the nanoparticles was characterized by FTIR spectrophotometry.

Respiratory Syncytial Virus is the most common cause of acute viral bronchiolitis and pneumonia in infants and young children. This study is designed to examine the presence of anti-RSV IgM and IgA antibodies in infants and young children aged between 2 months up to 5 years old. ELISA was used to examine the levels of IgM and IgA antibodies in the serum samples from 90 individuals (60 are with respiratory symptoms and 30 healthy as controls). The results were analysed by systematically dividing those individuals into two groups according to their age and clinical status. The age groups included infant between 2 months and 1 year of age and young children between 2-5 years whereas the clinical grouping includes the severity of infection o
