Catalytic Reforming of Iraqi Naphtha over Pt-Ti / HY Zeolite Catalyst
...Show More Authors

In the present work, zeolite Y has been synthesized successfully by sol-gel method.Zeolite was synthesized by crystallization of the final gel which consist from seeding and feed stock gels at  85 oC. HY zeolite was prepared by an ion exchange process with ammonium chloride solution and then loaded with different percentages of  platinum and titanium by the wet - impregnation method.

X-ray Diffraction (XRD), X-ray Florescence (XRF), Scanning Electron Microscopy (SEM), BET surface area and, Crushing strength were used to characterize the synthesized and prepared catalysts . Results showed high crystallinity  90%  with silica to alumina ratio 5 for HY, high surface area of 600 m2/g and pore volume of 0.38 cm3/g.

The activity of the prepared zeolite was investigated using a pilot plant unit for the catalytic reforming of Iraqi heavy naphtha. All prepared catalysts were investigated at temperatures of 490,500 and 510oC ,pressure of 20 bar, H2 /HC  ratio 3 and LHSV 1.4.hr-1.

Reformate was produced with 86 RON and 94% yield at 510ºC and 20 bar using 0.13 wt.% Pt - 0.75 wt.% Ti  loaded on synthesized HY.

Association Between Lipid Profile ,BMI , and Some Pituitary Hormones Abnormalities In Sera of Iraqi Infertile Females
...Show More Authors

In this study , the clinical impact of interaction between gonadotrophin hormones (luteinzing hormone, LH, and follicle stimulating hormone ,FSH ) and prolactin PRL in serum of seventeen Iraqi infertile female with the lipid profile . In addition to control group involving age matched fertile females . Immunoradiometric assay ( IRMA ) technique for the determination of (LH , FSH and PRL) was utilized. The lipid profile { i.e. total cholesterol ( Tc ) , triglycerides (TG) , and high density lipoprotein – Cholestrol ( HDLc )} ,were evaluated by using colorimetric method , while{ low density lipoprotein cholesterol ( LDLc ) and very low density lipoprotein – cholesterol ( VLDLc )} , were evaluated by using a mathematical formu

Permeability Prediction in One of Iraqi Carbonate Reservoir Using Statistical, Hydraulic Flow Units, and ANN Methods
...Show More Authors

   Permeability is an essential parameter in reservoir characterization because it is determined hydrocarbon flow patterns and volume, for this reason, the need for accurate and inexpensive methods for predicting permeability is important. Predictive models of permeability become more attractive as a result.

   A Mishrif reservoir in Iraq's southeast has been chosen, and the study is based on data from four wells that penetrate the Mishrif formation. This study discusses some methods for predicting permeability. The conventional method of developing a link between permeability and porosity is one of the strategies. The second technique uses flow units and a flow zone indicator (FZI) to predict the permeability of a rock mass u

Assessment of Monocyte Chemoattractant Protein -1 and Fertility Hormones in Iraqi Women with Polycystic Ovarian Syndrome
...Show More Authors

Polycystic ovarian syndrome (PCOS) is a well-known endocrinopathy and one of the most frequent endocrine-reproductive-metabolic syndromes in women, which can result in reduced fertility. While the actual cause is unknown, PCOS is regarded as a complicated genetic characteristic with a great degree of variability. Moreover, hormones and immune cells, including both innate and acquired immune cells, are thought to interact in PCOS. Chronic low-grade inflammation raises the risk of autoimmune disease. The study's purpose is to investigate the chemokine monocyte chemoattractant protein-1 (MCP-1) and fertility hormones in samples of women patients with polycystic ovary syndrome (PCOS) in the City of Medicine. Sixty PCOS women comprise 30 heal

Knowledge and Attitudes Regarding Health Education among Sample of Iraqi Patients Attending Primary Health Care Centers
...Show More Authors

Background: Health education was put as one of the components of primary health care elements and was recognized as a fundamental tool to the attainment of health for all

Objective: To evaluate the Knowledge, attitude regarding health education & to find out if there is any association between the gathered data and certain variables (age, gender, educational level, occupation). Methods: A Cross-sectional study done at Al Mustansyryia Primary Health Care Center from the 1st of January to 1st of May 2016. All patients attending the Primary Health Care Centers who were above 18 years of age and willing to participate in the research (303) were included in t

Association of Admission Serum Resistin Level with Acute ST-Segment Elevation Myocardial Infarction in Iraqi Patients
...Show More Authors

Human resistin is an adipokine, with a possible link to coronary heart disease.A few studies were done about resistin in acute phase of ST-segment elevation myocardial infarction (STEMI) especially in Iraqi patients. Accordingly we design a study to investigate the association between resistin concentration and acute phase of STEMI in Iraqi patients.

The present study was carried out at Al-Yarmouk Teaching Hospital from December 2011 until June 2012. Serum resistin levels were measured in 50 patients with acute STEMI (mean age: 58.16 ± 11.73 years) at the first 12 hours of admission and 34 normal controls (mean age: 53.98 ± 15.46 years) matched for age, sex and other risk factors.

Determining the Concentrations of Elements in Tobacco Selected in Iraqi Markets Using X-Ray Fluorescence Technique
...Show More Authors

  X-rays fluorescence technology was used  to measure the concentrations of trace and toxic elements in tobacco smoke. One sample local and eight samples were imported selected from Iraqi markets. The results proved that tobaccos contain few concentrations of element (calcium, potassium, sodium, manganese, magnesium, chlorine, and sulfur), trace concentrations of element (aluminum, vanadium, iron, cobalt, nickel, copper and zinc), and toxic concentrations of element (arsenic, selenium, bromine, antimony, cadmium, mercury and lead). Results are proved the concentrations of elements of samples are lower levels with the other countries in few element like (calcium, potassium, sodium and manganese), while the other elements were hi

Study the effect of Iraqi weather parameter in FSO communication using different wavelength (650, 532) nm
...Show More Authors

Light has already becomes a popular means of communication, and the high-bandwidth data into free space without the use of wires. A great idea took us to design a new system for transmitting sound through free space at (650, 532) nm wavelengths using reflective mirrors under different atmospheric conditions. The study showed us the effect of various weather factors (temperature, wind speed and humidity) on these wavelengths for different distances. As well as studying the attenuation caused by long-distance laser and beam divergence, A reflective dish was used to focus the spot of the laser beam on the photocell. Results were discussed under the effect of these factors and the attenuation resulting from the beam divergence. Thus, the sys
