In the present work we modulate a mathematical function to use it as a target function to represent the magnetic field distribution for the double pole-pieces magnetic lens. This function has, in fact, two optimization parameters. The only important parameter is the half half-width of the field for the proposed magnetic lens, which can affected objective properties, when the other one optimization parameter (lens length) is constant, which is the literature survey proved that unaffected on the lens properties. Results have clearly shown that the optimization parameter for current function has a considerable effect on the lens aberrations, and the reconstructed pole-pieces.

In the present research, the homogeneity tests were conducted for 36 meteorological stations records throughout Iraq. For this purpose, monthly and annual total rainfall records at stations operated by Iraqi meteorological organization and seismology (IMOS) from 1981 to 2010 were considered. Four methods namely standard normal homogeneity test (SNHT), Buishand range test, Pettitt test, and von Neumann ratio tests were chosen to detect the inhomogeneity of the rainfall time series. The results of each of the testing methods were evaluated separately at a significance level of 95% and the inhomogeneous years have been determined. With the application of the four mentioned methods, inhomogeneity was detected at 30% of stations (11 stations) and 70 % of stations (25 stations) were found to be homogeneous. The results of the different tests are condensed into three classes: ‘useful’, ‘doubtful’ and ‘suspect’. A qualitative interpretation of this classification is given, 31 stations were assigned as useful, two stations were labeled as doubtful and three stations were assigned as suspect.

The purpose of this study was to examine the effect of cigarette smoking on serum oxidative damage , antioxidant status in healthy subjects . Subjects were randomly chosen from Baquba community. Smoker( n=86) was defined as a person who had smoked 10 or more cigarettes per day continually for at least one year(1) , while non-smoker(n=39) was a person who had no previous smoking experience . The results show that the serum MDA levels were significantly higher ( p<0.05) in smokers compared with non smokers and lower significantly(p<0.01) serum glutathione , superoxide dismutase and catalase activities were in smokers than in non smokers. Thus increase levels of serum MDA and decreased antioxidant activities may be important in determining the oxidant / antioxidant imbalance in smokers

Classical ciphers were first used hundreds of years ago. As far as security is concerned, they are no match for today’s ciphers; however, this does not mean that they are any less important to the field of cryptology. A cipher system is one for which applying encryption algorithm to plaintext produces cipher text. The weakness with this strategy is that cipher text frequency distribution is not significantly altered by the encryption process. Swarm Intelligence (SI) is an artificial intelligence technique based on the study of collective behavior in decentralized and self- organized systems. This paper uses one of swarm intelligence optimization algorithms called Artificial Bees Colony (ABC) algorithm as an intelligent cryptographic tool to enhance the security of simple cipher system. An image data are used as the seed keys for the proposed cipher system, while the ABC algorithm is used to obtain the randomness for these keys. The results are successfully tested with randomness tests.

Diabetic foot (DF) is serious diabetes (DM) complication leading to delayed wound healing and may result in amputation. Osteoprotegerin (OPG) is a glycoprotein decoy receptor of RANKL(OPGL), involvement of OPG in the pathogenesis of diabetic complications has been proposed. Interactions OPG/OPGL has been proposed to be a major inhibiter of osteoclastogenesis (differentiation of osteoclasts cells),and OPG also has a role in the regulation of the immune response . This study was done to investigate whether the serum levels of circulating soluble osteoprotegerin, glycoprotein associated with the apoptosis, are altered in patients with type 2 diabetes whom have diabetic foot ulcerations. Osteoprotegerin was measured with the ELISA method in thirty (30) normal controls (group I), twenty five patients with type 2 DM (duration ranged from 1-32 years (group II) and in twenty five diabetic foot patients with type 2 DM (duration ranged from 2-31 years (group III). Also, serum glucose (Fasting), lipid profile (total cholesterol, riacylglycerol, HDL-c,LDL-c and VLDL-c) and hs-CRP were determined after 12hrs of fasting. Results: The patients with diabetic foot lesions were found to be poorly controlled and had significantly higher levels of fasting Plasma glucose (FPG) (p<0.05,p<0.001) when compared to patients whom without diabetic foot lesions and control groups. Also the patients with diabetic foot lesions were found have significantly higher levels of OPG when compared to patients without diabetic foot lesions and healthy control groups (p<0.01,P<0.001) respectively . Serum levels of total cholesterol, triacylglycerol, LDL-c and VLDL were significantly higher (p<0.05) in diabetic patients (with and without foot ulceration) in comparison with healthy normal control, while HDL-c level was lower in both groups than in the control group but not reach statistical significant. There are no significant different in lipid profile between diabetic foot patients and without diabetic foot patients. OPG serum levels were significantly increased in diabetic foot group as compared with patients whom without diabetic foot and normal control (10.82±2.87 ,6.16±6.18, ng mL
