Studies of mass transfer at a spiral-wound woven wire mesh rotating cylinder electrode
...Show More Authors

Mass transfer has been studied at rotating cylinder electrodes fabricated with spiral-wound woven-wire meshes using reduction of copper as a test reaction. The experimental data were correlated by an empirical expression between the Sherwood number and the Reynolds number, both regarding the hydraulic diameter as a characteristic length. It was found that the Sherwood number was dependent upon the Reynolds number to the power of 0.521. An enhancement factor was adopted to compare the efficiency of the new rotating cylinder electrode with previous three-dimensional rotating cylinder electrodes. The results showed that the new type has a mass-transfer enhancement factor 2.3 times higher than those obtained with smooth rotating cylinder electrodes under the same conditions.

Evaluation of the Hardness of Cold Cured Acrylic Resin Material by Processing at Different Temperature
...Show More Authors

Objective(s): This study aims to evaluate the hardness of two commercially available cold cured acrylic resin material
(Vertex and PAN) when polymerized at different temperature in comparison to those polymerized by conventional
methods in air at 23C ± 5C.
Methodology: Eighty specimens, forty from cold cured acrylic (Vertex Type) and forty from cold cured acrylic (PAN
type) were prepared, flasking and packing procedure were done according to manufacturer direction and divided
according to processing as follow: 20 specimens (10 from Vertex type and 10 from PAN type) were processed in air for
two hours at 23C ± 5C under press (bench curing) as a control, and 60 specimens (30 from Vertex type and 30 from
PAN type) wer

Evaluation of how laser photostimulation at two wavelengths alters the antimicrobial potential of Streptomycetes spp
...Show More Authors

The purpose of this study was to isolate and identify additional products produced by direct laser irradiation, as well as to ascertain if laser irradiation may stimulate the synthesis of antibiotic compounds in a local Streptomycetes (Strept). Moreover, we postulate the mechanisms by which lasers function within living bacterial cells and suggest that sequential photochemical reactions may transpire following a designated period of irradiation. Thiophene was found as one of the most significant clinical products with antibacterial and anticancer properties. To accomplish these objectives, we selected two isolates: Streptomyces thinghirensis strain S10 (Strept thin), which inherently synthesizes an antibacterial agent, and Streptomyces lien

The Effect of Tidal Energies on the Materials Properties of the Soil at Southern Mesopotamia
...Show More Authors

The materials of soil were affected by multi reasons; such as human activities, floods, tidal waves, ... etc. The change of the soil contents could be measured through different indexes; such as electric conductivities, salinity, concentration of the heavy elements, and concentration of essential elements ... etc. The land cover is affected by natural influences, like tidal energy, which plays a negative role in the salinization of land adjacent to the coasts, causing a problem for soils in all its details represented in changing of the dissolved elements in soil. One of the most important natural factors that cause soil salinity is human activity in all its forms, and one of the most important causes of salinity is the phenomenon o

The Effect of Quantum Confinement on Optical Properties of CdSe Quantum Dots at Room Temperature
...Show More Authors

CdSe quantum dots possess a tuning energy gap which can control gap values according to the size of the quantum dots, this is made the material able to absorb the wavelengths within visible light. A simple model is provided for the absorption coefficient, optical properties, and optical constants for CdSe quantum dots from the size 10nm to 1nm with the range of visible region between (300-730) nm at room temperature. It turns out that there is an absorption threshold for each wavelength, CdSe quantum dots begin to absorb the visible spectrum of 1.4 nm at room temperature for a wavelength of 300 nm. It has been noted that; when the wavelength is increased, the absorption threshold also increases. This applies to the optical propertie

Organizational Sustainability among Deans of Colleges at Anbar University from the Perspective of Department Heads
...Show More Authors

Background/purpose. This research aims to assess the level of organizational sustainability among deans of colleges at Anbar University from the perspective of academic department heads. Materials/methods. The current study sample consisted of 50 department heads, representing 50% of the total population of 101 academic department heads. The research followed a descriptive-analytical method. A questionnaire comprising three dimensions (economic, social, and environmental) was prepared and distributed to 50 heads of academic departments from various colleges at Anbar University between January 1 and February 6, 2025. The collected data were scrutinized statistically to evaluate the level of organizational sustainability. Results. The resea

Identify the Critical Risk Factors at the Tendering Phase in Iraq
...Show More Authors

Risk factors can be considered unique in construction projects, especially in tendering phase. This research is directed to recognize and evaluate the importance of critical risk factors in the tendering phase related to Iraq’s construction project. As a rule, construction projects are impacted by risk factors throughout the project life cycle; without identifying and allocating these risk factors, the project cannot succeed. In this paper, the open and closed questionnaires are used to categorize the critical risk factors in tendering phase. Research aims to recognize the factors that influence the success of tendering phase, to determine the correct response to the risk’s factors in this research article, (IBM, SPSS, V23) package has

...Show More Authors

     Fifty patients(24 female and 26 male)with pressure ulcersassociated with different diseasesand attending AL-yarmouk Teaching Hospital in Baghdad were selected in this study. The duration of sample collection was from March  to December 2018. All blood samples collected from patients were submitted to a blood culturing technique to examine bacteremia. The results showed that12 blood bacterial isolates were obtained. The isolated bacteria were subjected to Vitek-2, which is an accurate identification technique. The results of the blood culturing technique revealed that 33.3% were Gram negative bacteria, while 66.6% were Gram positive.
