Antibacterial effects of mineral trioxide aggregate and Biodentine TM after the addition of different concentrations of black seed aqueous solutions
...Show More Authors

Background: Mineral Trioxide Aggregate (MTA) and BiodentineTM cements are new materials with numerous exciting clinical applications. Both have appreciable properties which include good physical properties and the ability to stimulate tissue regeneration as well as good antibacterial effects. The aim of this study was to investigate and compare the antibacterial effects of MTA and BiodentineTM, when they were mixed with different concentrations of aqueous solutions of Black Seed extract, against Enterococcus faecalis. Materials and methods: MTA and BiodentineTMwere prepared according to the manufacturer’s instructions. The method of Mawlood was followed to prepare the Black Seed aqueous solution. Agar diffusion method on Brain Heart Infusion agar was employed.Twenty, 9 cm diameter, petri-plates with 25 ml of Muller Hinton agar media were prepared. A sterile spreader was used to inoculate the microorganisms. With a micropipette 0.1 ml of the Enterococcus faecalis suspension was added to the surface of the plates. Within 15 minutes, after inoculation of the plates, 4 cavities, each one measuring 5 mm in diameter and 4 mm in depth, were made in each agar plate. A total of 20 agar plates were divided into 2 groups consisted of 10 plates each; Group A: each plate contained 4 wells filled with MTA alone and MTA mixed with 10%, 30% and 50% of Black Seed aqueous solutions respectively.Group B: each plate contained 4 wells filled with BiodentineTMalone and BiodentineTMmixed with 10%, 30% and 50% of Black Seed aqueous solutionsrespectively. Next day after incubation, the agar plates were examined for bacterial inhibition zones. With a scientific ruler the diameter of the antibacterial inhibition zones were measured. The data were recorded and statistically analyzed, by the ANOVA and the Student's t-test. Results: Both cements had antibacterial effects, which were increased with the addition of the aqueous solutions of Black Seed extract. The increase in the diameter of Enterococcus faecalis inhibition zones was directly proportional with the increase in the concentration of the added Black Seed aqueous extract. Conclusion: Adding aqueous solutions of Black Seed extract to both MTA and Biodentine™ increased their potential to inhibit the growth of Enterococcus faecalis. Key words: Mineral Trioxide Aggregate, Biodentine TM, Black Seed.

The Effects of Intake Water Quality and Filtration Unit Performance on the Efficiency of the Al- Rasheed Water Treatment Plant in Baghdad, Iraq
...Show More Authors

     Water treatment plants play an important role in the purification and distribution of safe drinking water to the public. The present study focused on the performance assessment of the Al-Rasheed water treatment plant [ARWTP]. The main objectives of the assessment were to determine the efficiency of various plant units as well as the quality of inlet water from the Tigris River. Results obtained from the collected data indicated the presence of high concentrations of soluble nitrate and phosphate ions in the filtered water. The removal efficiency of alkalinity, EC, total hardness, SO4, Cl, NO3 and PO4 were found to be (+11.05%), (-0.67%), (-29.33%), (-2.64%), (-6.25%), (-32.13%), and (0%) respecti

Effects of multi- Deposition on the structural and optical properties of CdS nanocrystalline thin film prepared by CBD technique.
...Show More Authors

Cadmium sulfide (CdS) nanocrystalline thin films have been prepared by chemical bath deposition (CBD) technique on commercial glass substrates at 70ºC temperature. Cadmium chloride (CdCl2) as a source of cadmium (Cd), thiourea (CS(NH2)2) as a source of sulfur and ammonia solution (NH4OH) were added to maintain the pH value of the solution at 10. The characterization of thin films was carried out through the structural and optical properties by X-ray diffraction (XRD) and UV-VIS spectroscopy. A UV-VIS optical spectroscopy study was carried out to determine the band gap of the nanocrystalline CdS thin film and it showed a blue shift with respect to the bulk value (from 3.9 - 2.4eV). In present w

INTERACTION EFFECTS OF HYDRODYNAMICALLY FULLY DEVELOPED PRIMARY FLOW AND SECONDARY FLOW IN THE THERMAL ENTRANCE REGION OF ANNULAR DUCT
...Show More Authors

Experiments have been conducted to study the local and average heat transfer by mixed
convection for hydrodynamically fully developed, thermally developing and fully developed
laminar upward air flow in an inclined annulus with adiabatic inner cast iron tube and uniform
heated outer aluminum tube with an aspect ratio ( Ω = 0.72) and (L/Dh≈40) for both calming and
test sections). A wide range of Reynolds number from 859 to 2024 has been covered, and heat
flux has been varied from 159 W/m2 to 812 W/m2 (these values of heat flux and Reynolds
number gave Richardson number range from 0.03 to 0.٣٨), with angles of annulus inclination
φ =0o (horizontal position), φ =60o (inclined position), and φ =90o (vertical posi

Analytical Methods for the Identification of Pigments in Tattoo Inks and Some of Their Physiological Side Effects: A Review
...Show More Authors

In this review, numerous analytical methods to distinguish pigments in tattoo, paint, and ink items are discussed. The selection of a method was dependent upon the purpose, e.g., quantification or identification of pigments. The introductory part of this review focuses on describing the importance of setting up a pigment-associated safety profile. The formation of different degradation chemical substances as well as impurity trends can be indicated through the chemical investigation of pigments in tattoo products. It is noteworthy that pigment recognition in tattoo inks can work as a preliminary method to identify the pigments in a patient's tattoo before being removed by laser therapy. Contrary to the stud

Raman spectroscopy analysis for monitoring of chemical composition of aspirin after exposure to plasma flame
...Show More Authors

A Raman spectroscopy method was optimised to examine the chemical changes of aspirin tablets after interaction with helium temperatures. Several aspirin tablets were exposed to plasma-assisted desorption ionisation flame for different times (10, 30, 50, 60, 180 and 300s) and then analysed by Raman spectroscopy using optimal conditions. The changes in chemistry between exposed and fresh (without exposure to plasma) tablets were compared. The vibrational peaks of the aspirin molecule in the Raman spectrum were identified by checking the peak position. The results showed clear spectra with increases in intensity of vibrational peaks until 30s, whereas no spectra were measured for the exposed tablets to plasma flame after 50s. It can, the
