Objective: The aim of this study was to evaluate the effect of pumice, burning investment material
and black sand on the surface roughness of heat cure acrylic resin.
Methodology: Sixty specimens were prepared from pink heat cure acrylic resin, the specimens
where grouped into; 20 specimens which polished with pumice and water (control group); 20
specimens which polished with investment material (after burning it) and water; and 20 specimens
which polished with black sand and water. The average surface roughness of specimens after
polishing procedure had been determined by profilometer (surface roughness tester).
Results: Through the application of ANOVA and LSD tests, the result of this study showed that there

The objective of this research paper is two-fold. The first is a precise reading of the theoretical underpinnings of each of the strategic approaches: "Market approach" for (M. Porter), and the alternative resource-based approach (R B V), advocates for the idea that the two approaches are complementary. Secondly, we will discuss the possibility of combining the two competitive strategies: cost leadership and differentiation. Finally, we propose a consensual approach that we call "dual domination".
(Social values) are of great importance in the lives of nations and peoples as they are the frame of reference that governs the relations of members of society to each other and regulates their life affairs.
And the Prophet of Islam (may God’s prayers and peace be upon him) has told about a group of (social values) such as: spreading peace, feeding food, being fair in dealing with others, and clarifying what a Muslim should have towards his Muslim brother from the safety of the chest and refraining from harming him with the tongue and hand, and so on. Ethics and behaviors that are directly and closely related to (social values).

A spin coating technique was used to deposit CQDs/Alq3 composite film on glass substrates with a ratio of 1:1. The CQDs/Alq3 gas sensor showed a sensitivity of about 24٪ at a temperature of 300 ℃, and this was calculated after measuring the change in the resistance of the samples with a response time of 2 and 8sec recovery time. The sensor showed a good response for nitrogen dioxide (NO2) gas. However, the sensitivity, response time, and recovery time for the CQDs gas sensor when exposed to NO2 gas at 30

identified by isolation and histopathological changes of examined gills in
common carp fish (Cyprinus carpio) which, were obtained from fish farm in
Duhok Governorate, Iraq. The infected fish were suffering from respiratory
disorders; gulping air at the water surface, rapid movement of operculum and
massive mortality, which resulted in the loss of 95% of fish pond. The gills
appear marbled appearance with necrotic areas on the localized damage gills.
The causal pathogen was identified as Branchiomyces sanguinis, in which the
diameter of spores and non-septated hyphae are 5-7 μm and 12 – 20 μm,

The current study conducted in the Duhok province villages, Kurdistan region of Iraq during the period between September-December 2008, fulfilled by using Rosebengal and ELISA tests cattle of different sex and age were used comparing between these two tests and to determine the prevalence rate by both tests. A total number of 360 serum samples were collected (294 females, 66 males). The infected rate by RBT was 6.38% and by ELISA were 0.83%. According to the different animal ages and sex group showed that the infection rates were 5.4% and 12.1% in females and males, respectively. Cattle in age group 1-3 years and more than 4 years were showed that an infection rates were 3.8% and 11.8% respectively.
Osteoporosis is a common complication of ankylosing spondylitis (AS), and it is related to the high levels of biochemical markers such as tartrate-resistant acid phosphates (TRACP)-5b and other proinflammatory cytokines. In early AS, osteoporosis may appear due to the action proinflammatory cytokines, however spinal osteoporosis commonly observed in those patients with severe AS of long duration but it can occur as a result of ankylosis and lack of movement. Apelin is a new adipokine that has a negative impact on bone formation and can act as an anti-anabolic agent. The aim of this study is to evaluate serum (apelin and TRACP-5b) levels in ankylosing spondylitis (AS) male patients with and without osteoporosis and look for the relation b
