Comparative study of the radius of sensitivity of the optical model potentials for Li+Ni and O+Ni
Radii of sensitivity were estimated for the Li+Ni system at
energies near the Coulomb barrier. For comparison purposes, such radii were
also estimated for stable O scattered from same target isotopes. The
elastic scattering data were analysed with folded real potential generated from
DDM3Y nucleon-nucleon interaction and an imaginary potential of volume
Woods-Saxon form. The most sensitive radii for O+Ni system are
found to be energy independent and close to the strong absorption radius. For
Li projectile, unlike its strongly bound counterpart, the crossing radius
increases with decreasing energy. However, no two crossing situation has been
observed for both Li+Ni and O+Ni systems at
the top of the barrier.Comment: Accepted for publication as a Brief Report in Physical Review C (4

Ozone therapy in oxidative stress disorders and evaluation of C-reactive proteins [abstract]
It is well recognized that oxidative stress and oxidative damage to DNA, RNA, protein and cell membranes is responsible for early ageing and lifestyle disorders. In various pathological conditions the main problem is related to a rapid increase in the cellular ROS concentration that exceeds the capacity of the cell to eliminate them. ROS derived from the ozone therapy can exert its protective effects by means of an oxidative preconditioning, stimulating and/or preserving the endogenous antioxidant systems. The aim of this paper is to evaluate the ozone effects, in a preliminary clinical treatment in the oxidative stress disorders. We enrolled 12 patients having type2 diabetes who were prone for cardiovascular risk disorders. Ozone treatment improved glycemic control and prevented oxidative stress associated to diabetes mellitus and its complications. This was also correlated with lab testing of HbA1c and C-reactive protein levels before and after Ozone treatment of 20 rectal insufflation 20 sessions (with an ozone dose of 9000mcg, ozone concentration: 30 mcg/ml) and 10 Major Auto heamotherapy (with an ozone dose of 2000mcg, with Ozone concentration: 20mcg/ml) with Rectal twice a week and M-AHT once a week. C-reactive protein (CRP) predicts cardiovascular outcome. Oxidative stress is considered to be involved in endothelial alteration. CRP is used mainly as a marker of inflammation. Apart from liver failure, there are few known factors that interfere with CRP production. CRP levels are associated not only with clinical cardiovascular risk factors but also with oxidative stress. There are significant interrelationships among inflammation, oxidative stress, and traditional cardiovascular risk. Inflammation and oxidative stress play a key role in the pathogenesis of atherosclerosis. We examined the interrelationships among C-reactive protein (CRP), oxidative stress, and traditional cardiovascular risk factors. Ozone treatment significantly improved the antioxidant status of patients reducing biomarkers of protein and lipid oxidation, enhancing total intracellular antioxidant status. Improvement of blood circulation and oxygen delivery to ischemic and neoplastic tissues. Improvement of the general metabolism.Correcting the chronic oxidative stress by upregulating the antioxidant system. Induce a mild activation of the immune system and Procure a state of well-being in patients by activating the neuro-endocrine system. Conclusion. Ozone therapy given systemically improved patient's C-reactive protein from range of 20-34 mg/dL to the range of 4-5 mg/dL. General wellbeing was enhanced with better controlled blood sugar levels. These results may be preliminary but shows the efficacy of ozone therapy in oxidative stress disorders and inflammation markers

Association of feeding practices and immunization with nutritional status of infants in jasra block of Allahabad district
Objective: The objective was to find the association of feeding practices and immunization with nutritional status of infants in JasraBlock of Allahabad district. Materials and Methods: A cohort study was conducted in a rural community among infants born duringthe period of November 2011 to April 2012. Information, Education and Counselling was given to their mothers starting from last3 months of pregnancy and continued till the newborns completed 1-year of age. Then feeding practices, immunization, and nutritionalstatus (in terms of weight for age) was assessed. Results: About 56.25% infants were exclusively breastfed and 53.75% infants weretimely started on complementary feeding. 87.5% infants were fully immunized and the rest 12.5% were partially immunized. Growthof more than half of the infants, i.e., 47 (60%) followed a normal growth curve and weight of 33 (40%) infants was below 2 standarddeviation. There was no significant difference between the mean weight at birth (i.e., 2.56 kg for infants with adequate feeding andimmunization practices and 2.51 kg for infants with inadequate immunization and feeding practices). On the other hand, difference inthe mean weight among two groups at 3, 6, and 9 months was statistically significant. Conclusion: Feeding practices and immunizationhave an association with nutritional status of infants in terms of better weight for age
Generic Model Refactorings
Many modeling languages share some common concepts and principles. For example, Java, MOF, and UML share some aspects of the concepts\ud
of classes, methods, attributes, and inheritance. However, model\ud
transformations such as refactorings specified for a given language\ud
cannot be readily reused for another language because their related\ud
metamodels may be structurally different. Our aim is to enable a\ud
flexible reuse of model transformations across various metamodels.\ud
Thus, in this paper, we present an approach allowing the specification\ud
of generic model transformations, in particular refactorings, so\ud
that they can be applied to different metamodels. Our approach relies\ud
on two mechanisms: (1) an adaptation based mainly on the weaving\ud
of aspects; (2) the notion of model typing, an extension of object\ud
typing in the model-oriented context. We validated our approach by\ud
performing some experiments that consisted of specifying three well\ud
known refactorings (Encapsulate Field, Move Method, and Pull Up Method)\ud
and applying each of them onto three different metamodels (Java,\ud
MOF, and UML)
Efecto de procesos de ahumado frío y caliente y la adición de extracto polifenólico natural de Dunaliella salina sobre la calidad bioquímica y la vida útil de filetes de Sander lucioperca almacenados durante 90 días
The effects of cold and hot smoking and the addition of Dunaliella salina polyphenol extract on the biochemical quality and shelf-life of Sander lucioperca fillets after storage for 90 days at 0-4 °C were examined. The results showed a significant increase in protein, lipid, free fatty acid, and 1,1-diphenyl-2-picrylhydrazyl contents, and a decrease in peroxide and thiobarbituric acid reactive substances, and volatile base nitrogen levels in cold (CSF) and hot (HSF) smoked fillets covered with or without extract and stored for 1, 20, and 90 days compared to fresh fillets (FF). Saturated and monounsaturated fatty acids exhibited a significant increase in FF and CSF and HSF covered with or without extract. The total polyunsaturated fatty acids revealed a significant decrease in FF and CSF and HSF with or without extract. Therefore, cold and hot smoking and polyphenol extract improved the biochemical quality and storage shelf-life of fillets for 90 days at 0-4 °C.Se examinaron los efectos del ahumado en frío y en caliente y la adición de extracto de polifenoles de Dunaliella salina sobre la calidad bioquímica y la vida útil de filetes de Sander lucioperca almacenados durante 90 días a 0-4 °C.
