He-Ne Laser Irradiation Encourages reparative processes After cartilage loss in New Zealand rabbits

Many therapeutic methods used to encourage reparative processes of cartilage and accelerate their healing such as drugs, magneto-laser and so on. Twenty four adult New Zealand rabbits used in this study. They were divided in to two groups; control and treaded with He –Ne laser. A square skin flap done on the medial aspect of both auricles followed by pealing a square piece of cartilage from the auricle then the flaps sutured .The site of the operation in the rabbits of the treated group were irradiated with He –Ne laser 5mw power for seven days began after the operation directly. 3 rabbits from each group used for collection of specimens for histopathological examination at the 1, 2, 4 & 6 weeks post the operation. Significantly well developed cartilage growth, chondroblasts and chondrocytes invade the area of the operation .High increase in the thickness of connective tissue in the same area contain mainly collagen fibers and lesser amount of elastic fibers. He –Ne laser irradiation raised the mitotic activity of the cartilage cells, activated the reproduction processes in addition to the intra and extra regenerative repair

Improving Reverse Engineering Processes by using Articulated Arm Coordinate Measuring Machine

The invention relates to a coordinate measuring machine (CMM) for determining a measuring position of a probe. The AACMM isdepends on the robotkinematics (forward and reverse) in their measurementprinciple, i.e., using the AACMM links and joint angles todetermine the exact workspace or part coordinates. Hence, themeasurements are obtained using an AACMM will be extremely accurate and precise since that ismerely dependent on rigid structural parameters and the only source of measurement error is due to human operators. In this paper, a new AACMM design was proposed. The new AACMM design addresses common issues such as solving the complex kinematics, overcoming the workspace limitation, avoiding singularity, and eliminating the effects of

Removal of 4-Chlorophenoles from Simulated Wastewater by Advanced Oxidation Processes

The degradation and mineralization of 4-chlorophenol (4-CP) by advanced oxidation processes (AOPs) was investigated in this work, using both of UV/H2O2 and photo-Fenton UV/H2O2/Fe+3 systems.The reaction was influenced by the input concentration of H2O2, the amount of the iron catalyst, the type of iron salt, the pH and the concentration of 4-CP. A colored solution of benzoquinon can be observed through the first 5 minutes of irradiation time for UV/H2O2 system when low concentration (0.01mol/L) of H2O2 was used. The colored solution of benzoquinon could also be observed through the first 5 minutes for the UV/H2O2/Fe+3 system at high
concentration (100ppm) of 4-CP. The results have shown that adding Fe+3 to the UV/H2O2 system enhanced

Nanofluids for Enhanced Oil Recovery Processes: Wettability Alteration Using Zirconium Oxide

Ultimate oil recovery and displacement efficiency at the pore-scale are controlled by the rock wettability thus there is a growing interest in the wetting behaviour of reservoir rocks as production from fractured oil-wet or mixed-wet limestone formations have remained a key challenge. Conventional waterflooding methods are inefficient in such formation due to poor spontaneous imbibition of water into the oil-wet rock capillaries. However, altering the wettability to water-wet could yield recovery of significant amounts of additional oil thus this study investigates the influence of nanoparticles on wettability alteration. The efficiency of various formulated zirconium-oxide (ZrO2) based nanofluids at different nanoparticle concentrations (0

Impact of weight loss achieved through gastric sleeve surgery with circulating level of ghrelin hormone in obese Iraqi subjects.

Back ground: The epidemic of obesity is a major health problem in the developed world with a great influence on morbidity and mortality.
The aim of study: to evaluate serum ghrelin levels achieved through LSG and on insulin resistance and the serial changes of insulin concentration in obese patients following gastric sleeve.
Patients and methods: twenty four patients underwent LSG with 25 controls were selected. Body mass index (BMI), waist circumference (WC), lipid profile, fasting blood sugar (FBS), glycated hemoglobin (HbA1c), fasting insulin, QUICKI and ghrelin hormone concentrations were measured for controls and patients prior LSG, then one month and three months post-surgery.
Results: A significant decline was noticed in

The Iraqi- Kuwaiti relations after 2003

The Iraqi- Kuwaiti relations had witnessed a lot of problems which had its impact on them, at the fore front is the frontier issue, and the Iraqi invasion of Kuwait in 1990 which led to the severance of relations between them and had strengthened the disagreement and the dispute and raised the animosity and tension.
After 2003, Iraq has witnessed a lot of changes which affected Iraq and the region as a whole.
Under the new political developments in Iraq, a now phase has started in the relations between the two parts. which is based on the emphasis on building new relations based on the mutual respect and non intervention in the internal affairs of both countries, and in accordance with the principles of the international law, and w
