Combining Electro Fenton With Adsorption Processes for Treatment of Petroleum Refinery Wastewater
...Show More Authors
ABSTRACT<p> This study investigates the elimination of chemical oxygen demand (COD) from an Iraqi petroleum refinery effluent through a combined electro‐Fenton and adsorption process (EF+AC). Response surface methodology (RSM) with a Box–Behnken design (BBD) was employed to investigate the effects of FeSO <sub>4</sub> concentration, current density, and electrolysis time on the reduction of COD using the EF technique. According to the results of the analysis of variance (ANOVA) for the EF technique, FeSO <sub>4</sub> concentrations, with a contribution of 40.06%, and current density, with a contribution of 46.35%, exert a considerable influence. The optimum conditions for COD elimination rate (99.06%) and energy consumption (9.805 kWh/kg COD) were achieved using an electrolysis time of 85.12 min, a current density of 25 mA/cm <sup>2</sup> , and a concentration of 1.335 mM FeSO <sub>4</sub> . For the EF+AC process, a central composite design (CCD) was used to determine the influence of the packing level of activated carbon (AC) and the time on the reduction of COD at a constant current density of 5 mA/cm <sup>2</sup> and FeSO <sub>4</sub> concentration of 0.2 mM. The packing level of AC significantly influenced the elimination of COD, with time being the subsequent factor. The results showed that the optimal conditions led to a 98.77% removal of COD, requiring 0.91 kWh/kg COD. This efficiency and energy consumption were attained by using 92% packed AC and allowing the process to run for 85 min. EF+AC was found to have lower energy consumption and a smaller quantity of ferrous sulfate compared to EF. Notably, the current system offers a promising vision by combining the benefits of adsorption and electro‐Fenton for wastewater remediation. </p>

Treatment of Oral Conditions by 810 nm Diode Laser
...Show More Authors

When laser light incident on biological tissue, it is either reflected from the
surface of the tissue (e.g. the skin) or scattered inside the tissue or absorbed .The laser light will be
absorbed by water, hemoglobin and melanin. Absorption is also highly dependent on wave-length of
laser radiation. The absorbed light is converted into kinetic energy leading to laser effect that when
appropriately applied can produce reaction ranging from incision, vaporization to coagulation. Aim of
the study: To evaluate the efficiency of diode Laser 810 ± 20nm in treatment of oral lesions. Methods:
6 patients (2 females and 4 males) with different oral lesions were treated in the hospital of specialized
surgeries by the use of dio

Treatment of Spider Veins Using 810 nm Diode Laser
...Show More Authors

Spider veins are a common aesthetic problem mainly in females , the conventional method of treatment is by microsclerotherapy (injections) but laser therapy has become increasingly efficacious and a convenient method for treatment. The present study was performed to investigate the effectiveness and safety of pulsed diode laser (810nm) by doing thermal photocoagulation. Ten patients with lower limbs spider veins were included in this prospective study. They were treated with a repetitive pulsed diode laser in non contact technique using the following laser parameters (wave length 810nm,power 1 W ,pulse duration 0.1 s., pulse interval 0.5 s, spot diameter 4mm ,power density 7.9 W/cm2). Laser therapy was performed on day zero and day fourt

PHYSIOLOGICAL ROLE OF IMMUNE SYSTEM ELEMENTS IN ORTHODONTIC TREATMENT
...Show More Authors

Orthodontic treatment is an inclusive treatment that includes growth adjustment of the craniofacial area and alveolar bone reconstruction that affects the movement of teeth. Apply orthodontic forces to correct teeth anomaly via alveolar bone remodeling includes a combination of cellular and molecular events in the gum. Orthodontic tooth movement is based on force induced periodontal ligament and alveolar bone remodeling. Mechanical motivation on a tooth causes an inflamed response in the gum tissue. Inflammatory immune markers stimulate the biological processes associated with alveolar bone resorption. The aim of this article is shedding light on the significance role inflammatory immune response in orthodontic treatment.
