STUDY OF THE EFFECT OF MAGNETIC FIELD POLES ON THE GROWTH OF Staphylococcus AND Streptococcus ISOLATED FROM TOOTH DECAY: STUDY OF THE EFFECT OF MAGNETIC FIELD POLES ON THE GROWTH OF Staphylococcus AND Streptococcus ISOLATED FROM TOOTH DECAY
...Show More Authors

The study aimed to determine the impact of energy for the north and south magnetic poles on the the growth of bacteria isolated from cases of tooth decay, 68 swabs were collected from surfaces of faulty tooth, the detected of Staphylococcus aureus, Staphylococcus epidermids and Streptococcus mutans for isolation and then diagnosed using phenotypic diagnostic methods and biochemical tests. The results showed that 28 isolates (41%) were S. aureus and 23 isolates (34%) were S. epidermids and 17 isolates (25%) were Streptococcus mutans.

Exposed isolates to magnetic field poles of north & south and two together to see the effect of polarity on the growth and vitality of bacterial isolates, the results showed that north pole has been negative effect on the growth of bacteria, reduce numbers and inhibition growth with varying degrees while south pole showed positive effect in increasing numbers of bacteria while gave poles together moderate effect between the north pole and the south pole

           With regard to the impact of antibiotics such as cephalothin, erythromycin, penicillin, tetracycline and novabiocin on growth of bacterial isolates, the results showed that S. aureus was resistant to the most antibiotics, while varied ratios inhibition for other isolates, and when studying the effect of the magnetic field with antibiotic together on the growth of isolates, there was an increase the sensitivity of the bacterial isolates to the antibiotic under magnetic field compared to the sensitivity toward antibiotic alone..

Study of The Effect of Concentration on The Efficiency of The Sensitive N749-TiO<sub>2</sub> Solar Cell
...Show More Authors
Abstract<p>In this research, we studied the effect of concentration carriers on the efficiency of the N749-TiO<sub>2</sub> heterogeneous solar cell based on quantum electron transfer theory using a donor-acceptor scenario. The photoelectric properties of the N749-TiO<sub>2</sub> interfaces in dye sensitized solar cells DSSCs are calculated using the J-V curves. For the (CH3)3COH solvent, the N749-TiO<sub>2</sub> heterogeneous solar cell shows that the concentration carrier together with the strength coupling are the main factors affecting the current density, fill factor and efficiency. The current density and current increase as the concentration increases and the </p> ... Show More

Effect of cold plasma technique on the quality of stored fruits - A case study on apples
...Show More Authors

The consumption of fresh fruits has increased nowadays due to the lifestyle of the consumers. Maintaining the quality and nutritional value of cut fruits during storage is difficult compared to whole fruits. Deterioration of internal and external quality usually occurs in freshly harvested fruits. It is necessary to use different techniques to maintain the quality and increase the shelf life of the freshly cut product. This research studied the effect of treating apple slices with cold plasma once and with filtered water again on quality characteristics (hardness, moisture content, sugar content, carbohydrate content, and color) after being stored for five days. The best treatment was determined using two different pressures of the plasma j

Laboratory Study on the Effect of Water-Cement Ratio on Strength Characteristics of Jet Grouting Columns
...Show More Authors

Jet grouting is one of the most widely applied soil improvement techniques. It is suitable for most geotechnical problems, including improving bearing capacity, decreasing settlement, forming seals, and stabilizing slopes. One of the difficulties faced by designers is determining the strength and geometry of elements created using this method. Jet grouted soil-cement columns in soil are a complicated issue because they are dependent on a number of parameters such as soil type, grout and water flow rate, rotation and lifting speed of monitor, nozzle jetting force, and water to cement ratio of slurry. This paper discusses the effect of the water-cement ratio on the physical and mechanical characteristics of soilcrete. In t

The current study, which extended from February 2020 to June 2021 at the University of Thi- Qar\ College of Education for Pure Sciences, aimed to follow the changes in external morphological features at different Embryonic Developmental stages in pregnant mice treated with different doses of Rapamycin (Rapa). Use In this study, 32 pregnant mice were divided randomly into four groups, each of which had eight pregnant mice. Each group received different dose of Rapa via intraperitoneally injection at different gestation days until the end of the specified periods, whereas the control group received a DMSO. Mice were administered under the same circumstances and dosages were determined based on body weight, as specified in pharmaceutical const

Abstract:In this research we prepared nanofibers by electrospinning from poly (Vinyl Alcohol) / TiO2. The spectrum of the solution (Emission) was studied at 772 nm. Several process parameter were Investigated as concentration of PVA, the effect of distance from nozzle tip to the grounded collector (gap distance), and final the effect of high voltage. We find the optimum condition to prepare a narrow nanofibers is at concentration of PVA 16gm, the fiber has 20nm diameter.
