The The Use of Copper and Aluminum Electrodes for Energy Production in a Microbial Fuel Cell
...Show More Authors

Microbial fuel cell is a device that uses the microorganism metabolism for the production of electricity under specific operating conditions. Double chamber microbial fuel cell was tested for the use of two cheap electrode materials copper and aluminum for the production of electricity under different operating conditions. The investigated conditions were concentration of microorganism (yeast) (0.5- 2 g/l), solutions temperature (33-45 oC) and concentration of glucose as a substrate (1.5- 6 g/l). The results demonstrated that copper electrode exhibit good performance while the performance of aluminum is poor. The electricity is generated with and without the addition of substrate. Addition of glucose substrate up to 3 g/l increased the produced current but with further increase of the amount of substrate, the current generated decreases.  The optimum temperature for electricity production was found to be 36 oC.

Studying the Changes in Solar Radiation and Their Influence on Temperature Trend in Iraq for a Whole Century
...Show More Authors

Most studies indicated that the values ​​of atmospheric variables have changed from their general rates due to pollution or global warming etc. Hence, the research indicates the changes of direct solar radiation values ​​over a whole century i.e. from 1900 to 2000 depending on registered data for four cities, namely (Mosul - Baghdad - Rutba - Basra. Moreover, attemptsto correlate the direct solar radiation with the temperature values have been ​​recorded over that period. The results showed that there is a decreasing pattern of radiation quantities over time throughout the study period, where the value of direct radiation over the city of Baghdad 5550 w/m2 was recorded in the year 1900, but this ratio decreased cle

Iraqi Experience of Factor VII use in Children
...Show More Authors

Bleeding disorders in pediatrics is an important issue and can be lifethreatening if not diagnosed and treated appropriately. We aimed to evaluate Iraqi pediatric practice (as an example of resource-limited settings) about the use of Recombinant Activated Factor VII (RFVIIa) in bleeding disorders, with emphasis on its effectiveness and safety, in comparison with adjuvant therapy. Budget restrictions may affect the availability of even lifesaving drugs such as (RFVIIa). Therefore, we tried to investigate the local experience of pediatric bleeding, with the evaluation of the potential ability of adjuvant therapy of blood products and vitamin K to substitute RFVIIa in case of non-availability. During a complete one year‘s period, 35 patients

A Comparative Analytical Study of Some Biomechanical Variables and Their Relationship to The Accuracy of The Performance of The Shooting Skill of Jumping High in The Weak and Strong Foot the Players for Youth Handball
...Show More Authors

The research aims to identify the most important variables affecting shooting from jumping high and compare them for the two foot the weak and strong, where the researchers adopted the descriptive method, and the sample was chosen by the intentional method, which consists of (4) players from the Iraqi Sports Army Club, where these variables were studied and their impact on The accuracy of aiming at the two men, and the researchers concluded that most of the players have more accuracy in aiming at the strong leg than at the weak leg, which leads to the loss of many real opportunities during the match because of the players changing the situation or wasting the available opportunity when the position of correction is an opportunity for the w

Natural Pigment –Poly Vinyl Alcohol Nano composites Thin Films for Solar Cell: nanocomposites thin film
...Show More Authors

Solar cells thin films were prepared using polyvinyl alcohol (PVA) as a thin film, with extract of natural pigment from local flower. A concentration of 0.1g/ml of polyvinyl alcohol solution in water was prepared for four samples, with various concentrations of plant pigment (0, 15, 25 and 50) % added to each of the four solutions separately for preparing (PVA with low concentrated dye , PVA with medium concentrated dye and PVA with high concentrated dye ) thin films respectively . Ultraviolet absorption regions were obtained by computerized UV-Visible (CECIL 2700). Optical properties including (absorbance, reflectance, absorption coefficient, energy gap and dielectric constant) via UV- Vis were tested, too.  Fourier transform infra

The Famous Muslims' Graveyards in the Persian Country in the Islamic Ages: A Historical Study in the Maraqid Al-Maaraf Book for Harz Aldeen
...Show More Authors

There are many studies that discussed the famous museum's graveyards in the Islamic worlds, to study the lives of these figures, there are many difficulties for their studies because the first we need the regularity and history information, and many sciences support, such as in language, geography information.

I am studying the research from Maraqid Al-Maaraf book by Harz Aldeen, the book has large members about the persons have graved in Persian Country in the middle ages, there are more than (30) figures in my study, I have studied every figure in this research depending on the sources and references books.

Ijarah and lease ending with ownership and its implications for the bank's profits: A case study in the Emirates Islamic Bank and Emirates NBD
...Show More Authors

The formula of Ijarah and Ijarah ending with ownership is one of the investment formulas in Islamic banks, so this research has shed light on it in order to benefit from the experiences of the research sample banks, This research aims to find a reliable way for Iraqi Islamic banks, namely (leasing and leasing ending with ownership) in order to invest their money without usurious interests, The problem of the research emerges through the lack of awareness of the Iraqi Islamic banks to work with different Islamic financing formulas and their inability to invest their money through the adoption of their administrations for different formulas, including the leasing, and this is reflected in the decrease and fluctuation of its profits, Theref

Removal of Copper from Simulated Wastewater by Applying Electromagnetic Adsorption for Locally Prepared Activated Carbon of Banana Peels
...Show More Authors

The adsorption of copper ions onto produced activated carbon from banana peels (with particle size 250 µm) in a single component system with applying magnetic field has been studied using fixed bed adsorber. The fixed bed breakthrough curves for the copper ions were investigated. The adsorption capacity for Cu (II) was investigated. It was found that 1) the exposure distance (E.D) and strength of magnetic field (B), affected the degree of adsorption; and 2) experiments showed that removal of Cu ions and accumulative adsorption capacity of adsorbent increase as the exposure distance and strength of magnetic field increase.
