Design and manufacturing of supercritical drying autoclave for aerogel production
...Show More Authors

This article will address autoclave design considerations and
manufacturing working with high pressure low temperature
supercritical drying technique to produce silica aerogel. The design
elects carbon dioxide as a supercritical fluid (31.7 oC and 72.3 bar).
Both temperature and pressure have independently controlling
facility through present design. The autoclave was light weight (4.5
kg) and factory-made from stainless steel. It contains a high pressure
window for monitoring both transfer carbon dioxide gas to liquid
carbon dioxide and watching supercritical drying via aerogel
preparation process. In this work aerogel samples were prepared and
the true apparent densities, total pore volume and pore size
distribution, BET surface area, spectroscopic refractive index,
structure and thermal properties have been systematically
investigated characteristic.

The Effect of Pyriproxyfen on Eggs and Female Adults Production of The Sitophilus oryzae L.
...Show More Authors

A series of tests were conducted to determine the susceptibility of eggs and neonates of the Rice Weevil Sitophilus oryzae L. (Coleoptera: Curculionidae), exposed to the insect growth regulator, Pyriproxyfen, on filter paper and on rough rice. In the first test, the hatch rate of eggs exposed on filter paper treated with Pyriproxyfen at the label rate of 0.003 mg [AI] /cm2 when used as a surface treatment in structures was 52.0 ± 7.3% compared to 93.0 ± 3.3% on untreated controls. In the second test, eggs were exposed to a dose-response series of 0.00003 to 0.03 mg [AI]/ cm2. Egg hatch was directly proportional to concentration and anged from 85.0 ± 2.0% on untreated controls to 26.7 ± 8.3% at the highest concentration tested. In the

Effect of fertilizers starter solutions on growth and production of broccoli (Brassica oleracea var. italica) 
...Show More Authors

The seedlings of vegetables are exposed to stress states, especially through the first period, due to injuring their roots by transplanting or heavy rain , so it is necessary to provide an available nutrient to recover the growth and increase their early yield, which means more income for farmers. In this regard, an experiment was conducted in the College of Agricultural Engineering Sciences, Agriculture Faculty, University of Baghdad, Iraq to study the effect of different types and concentrations of mineral fertilizers as starter solutions by using high nitrogen (N), high phosphorus (P) and neutral fertilizers (Q) at three levels which were 4 g/l (S1), 8 g/l (S2) and 12 g/l (S3) on broccoli growth and yield. The results showed tha

Production of Biodiesel Fuel from Oleic Acid and Comparison of its Properties with Petroleum Diesel
...Show More Authors

Biodiesel define as the mono-alkyl esters of vegetable oil and animal fats is an alternative diesel fuel that is steadily gaining attention because the combustion of fossil fuels such as coal, oil and natural gas has been identify as a major cause of the increase in the concentration of carbon dioxide in the earth’s atmosphere and causing global warming.
The present work concerns with estimating the physical properties experimentally such as kinematic viscosity, density, flash point and carbon residue of biodiesel that produced by the esterification reaction of methanol and oleic acid with homogeneous catalysts H2SO4 in a lab-scale packed reactive distillation column using the best operating conditions of methanol to oleic acid 8:1,

Production of Inflammatory Markers (IL-8, IL-4and IFN- )and risk of Ischemic Hart Diseases.
...Show More Authors

Background: Ischemic heart diseases (I.H.D) become the most common cause of sudden death, and is also the most common reason for death of man and women over 20 years of age in the world. Many Factors Play a role in pathogenesis of I.H.D. among those could be Immune – inflammatory markers which may lead to development of this disease.The present study was conducted to obtain more clarification about the impact of some immuno – inflammatory markers (IL- 8 , IL- 4 and IFN- Ճ) on the Clinical expression of heart disease among Iraqi patients .
Patients and methods: Hundred Iraqi patient with I.H.D. (80 male and 20 female) ages ranged between 20 to 80 year were involved in this study, include 4 subgroups:
