Investigation of heat transfer phenomena and flow behavior around electronic chip
...Show More Authors

Computational study of three-dimensional laminar and turbulent flows around electronic chip (heat source) located on a printed circuit board are presented. Computational field involves the solution of elliptic partial differential equations for conservation of mass, momentum, energy, turbulent energy, and its dissipation rate in finite volume form. The k-ε turbulent model was used with the wall function concept near the walls to treat of turbulence effects. The SIMPLE algorithm was selected in this work. The chip is cooled by an external flow of air. The goals of this investigation are to investigate the heat transfer phenomena of electronic chip located in enclosure and how we arrive to optimum level for cooling of this chip. These par

The judgment enjoys many potential sources. If we look at these sources with analytical view that enable us to identify the potentials of strength in them which is the existence of features that distinct each place from the other one, which can be considered opportunities that provide the designer and the planner the possibility to design and planning which is based on subs taken from the reality of the available data of the location.
At this point outstands the role of development sources as one of the processes of re-configuring the place which appear as a result of a reality that requires setting new goals for the society and to achieve these goals it takes observations dealing with the place policies that should be taken, so this

Background: Herbs are being widely explored to discover alternatives to synthetic antibacterial agents.Small Cardamom often referred to as queen of spices because of its very pleasant aroma and taste, have a history as old as human race. Most people use cardamom as a spice and are largely unaware of its numerous health benefits. The purpose of this study was to evaluate the effect of different concentrations of water and alcoholic cardamom extracts on sensitivities, growth, and adherence of Mutans streptococci in vitro. Materials and Methods: In this study, saliva was collected from ten volunteers (College students 18-22 years). Agar well technique was used to study the sensitivities of Mutans streptococci to different concentrations of s

Determination of Uranium Concentration in Soil of Baghdad Governorate and its Effect on Mitotic Index Assay
...Show More Authors

The aim of this work is to determine the uranium concentration in soil samples
taken from the north, south, east, west and center of the city of Baghdad and
measure its impact on the rate of cell division for non-smokers peoples and living in
those areas and that between the ages 25-30 year.
The uranium concentration in the samples determined by using CR-39 track
detector . As calculated for the ten samples of each site when irradiated by thermal
neutrons from the (Am - Be) source with flux (5x 103 n S-1cm-2), the concentration
values were calculated by a comparison with standard geological samples. The
results indicate that the extent of the concentration of uranium in the soil north and
east of Baghdad was 12

One of the major environmental problems is the pollution of water and soilsby toxic
heavy metals.The aim of current study was estimatation the ability of Eclipta alba
plant for the removal of (Pb) from the polluted water by phytoremedation technique
and study the effect of a number of parameters(Pb concentration, contact time and
pHvalues). The plant showed higher removal efficiency (99.2%) after 7 days of
treatment at 50ppm.The best removal efficiency of Pb 98.95% at 100ppm was
occurred at pH7. The root ability to accumulate Pb was more than the shoot ability,
after 7 days treatment of water and pH=7, they were 2852.5 mg/kg, 2497.5 mg/kg
and 502.5 mg/kg in roots, stems and leaves respectively. These results showe

In this paper, we apply the notion of a bipolar fuzzy n-fold KU-ideal of KU- algebras. We introduce the concept of a bipolar fuzzy n-fold KU-ideal and investigate several properties. Also, we give relations between a bipolar fuzzy n- fold KU-ideal and n-fold KU-ideal. The image and the pre-image of bipolar fuzzy n-fold KU-ideals in KU-algebras are defined and how the image and the pre- image of bipolar fuzzy n-fold KU-ideals in KU-algebras become bipolar fuzzy n- fold KU-ideals are studied. Moreover, the product of bipolar fuzzy n-fold KU- ideals in Cartesian product KU-algebras is given.

Nannobiostratigraphy of Serikagni Formation in Southern limb of Sinjar anticline, Northwestern Iraq
...Show More Authors

Investigations of calcareous nannofossils were done on the Serikagni Formation in the southern limb of the Sinjar anticline northwest of Iraq, specifics of the identification process's investigation (18 species of calcareous nannofossils belonging to 10 genera). Two biozones were proposed in this study based on their stratigraphic distribution, and they are as follows: Triquetrorhabdulus carinatus partial range Biozone CN1 and Sphenolithus belemnos Interval Biozone CN2. Correlation with other calcareous nannofossil biozones from regional schemes led to the conclusion that the Serikagni Formation's age is Early Miocene (Aquitanian)in the studied sections. It can conclude from higher speciation for calcareous nannofossils that the bloom at

The Effect of Meta-heuristic Methods on the Performance of ImageClassification
...Show More Authors

Classification accuracy is strongly affected by the quality of the input features. In recent years, datasets have increased in size and number of features. Analysis of huge datasets can be challenging due to redundant, noisy, and irrelevant features that may
reduce the classifier's performance. Feature selection is a vital process in which the best subset of features from the original dataset is chosen. The feature selection strategy is critical for increasing classification accuracy while decreasing computational costs. This research proposed a method for classifying lip print images by exploiting meta-heuristic methods and optimization-based feature selection methods. It involves four main phases: pre-processing, feature extractio

Antibacterial and Antibiofilm of Purified β-glucan from Saccharomyces cerevisiae against Wound Infections Causative Bacteria
...Show More Authors

Twenty species were isolated from wounds’ swabs. The most common bacterial species were Pseudomonas aeruginosa (8), Staphylococcus aureus (5), Escherichia coli (5) and S. epidermidis (2). These isolates underwent tests for biofilm formation and susceptibility to ten different antibiotic discs. Most isolates exhibited resistance to amikacin, aztreonam, and carbenicillin. However, they showed some sensitivity to ciprofloxacin, norfloxacin and imipenem. This study found out that all isolates were different in biofilm formation (weak, moderate, strong), except two isolates of E. coli. The determination of β-glucan effects produced by S. cerevisiae against multi-antibiotic resistant wound infection bacteria, were conducted through the Mini

In this paper, an approximation technique is introduced to solve the coupled linear parabolic boundary value problems with variable coefficients by using mixed of the Galerkin finite element method in space variable with implicit finite difference method in the time variable. At any discrete time this technique is transformed the coupled linear parabolic boundary value problems with variable coefficients into a linear algebraic system which is called a Galerkin a linear algebraic system, and then it is solved using the Cholesky Decomposition. Illustration examples are presented and the results are shown by figures and tables, and show the efficiency of the proposed method.
