Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Background. Hepcidin is a master regulator of iron metabolism that inhibits the transport of iron out of enterocytes and macrophages. Thalassemia major (TM) is associated with some of the endocrine disorders. However, studies have yet to be conducted on the correlation of hepcidin with hormone levels and insulin resistance (IR) in patients with TM.Objectives. In the present study, the correlation of hepcidin level with some endocrine and biochemical parameters was investigated to determine the factors that mainly affect hepcidin correlation in patients with thalassemia. These factors include hormones, iron status, and IR parameters.Material and Methods. Hepcidin and other measured biochemical parameters were compared between the TM patients (100) and healthy children (37).Results. Serum thyroid-stimulating hormone (TSH) was positively correlated (p < 0.05) with hepcidin, iron, and ferritin. T4 hormone was correlated with ferritin only. 56 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Composite coatings are obtained by simultaneously placing non-conducting and insoluble particles inside the metal substrate. These coatings have desirable mechanical properties and are more resistant to abrasion and corrosion than metal coatings. The degree of increase in their resistance depends on the morphology of the neutral fine particles inside the composite coating and their amount. Reducing the grain size of the substrate as well as reducing the diameter of the reinforcing particles improves the properties of the composite coating. Due to its simplicity and cheapness, low process temperature, ease of achieving nano structure and also producing high density and porosity-free coatings, electrical deposition method is one of the suitable methods for applying these coatings and has received special attention in the last few decades by researchers. 72 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -So far, we know that corrosion in the oil and gas industry is a costly phenomenon and causes the loss of national capital, so it is logical that designers and engineers of oil and gas and petrochemical lines by carefully studying the behavior of all devices and materials involved in this industry to deal with Deal with the phenomenon of corrosion. According to the second equation, CO2 will combine with coke carbon to produce carbon monoxide. 64 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A FORTRAN program has been developed. New numerical results are generated for in - plane compressive biaxial buckling which serve to quantify the effects of lamination scheme on buckling loading. The results indicate that the symmetric laminate is stiffer than the anti - symmetric one. This phenomenon is caused by coupling between bending and stretching which lowers the buckling loads of symmetric laminate. The aim of the present textbook was to review the importance of studying buckling of composite laminated rectangular plates from the point of view of introduction and basic definitions, the formulation of mathematical modelling of rectangular laminates, the numerical method for predicting the buckling loads and shape modes of buckling of laminated rectangular plates, studying the effect of lamination scheme on buckling loads, and finally the important results and findings of the present study. 68 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A squid by-product gelatinous protein polymer (SBP) has been extracted, characterized and examined as eco-friendly inhibitor for carbon steel in 0.5 M H2SO4 media by weight loss, electrochemical techniques. It was found that the SBP acts as a good corrosion inhibitor. The inhibition efficiency increases with increasing inhibitor concentration, but the temperature has hardly affected on the inhibition efficiency of SBP. Thermodynamic data clearly show that the adsorption mechanism of SBP on the carbon steel surface in 0.5 M H2SO4 solution is mainly physical adsorption. Moreover, the adsorption of the SBP molecules was found follows a Langmuir adsorption isotherm. Results of potentiodynamic polarization measurements revealed that the SBP acts as mixed-type inhibitor. Data obtained from EIS studies were analyzed to model inhibition process through appropriate equivalent circuit model. Theoretical parameters derived from quantum chemical calculations as well as binding energy derived from molecular dynamics simulations studies adequately corroborate the trend of experimental inhibition efficiencies of the studied inhibitors. 88 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Most of the applications on EZT algorithm were applied on wavelet transformation. In the last ten years, the contourlet transformation has shown its higher efficiency compared to the wavelet transformation as it is able to deal with multidirections instead of the vertical and horizontal directions covered by the wavelet transformation.In the present research, the contourlet coefficient has been adopted as an input to the EZT (which are normally a wavelet coefficient). Arranging the contourlet coefficient to be studied as an input to EZT, the result of adopting modified contourlet coefficient has been studied on two parameters, namely the file size and threshold value, and also been tested by evaluating three factors, viz. correlation, MSE and PSNR.Studying the effect of the contourlet coefficient to see which of them have the high effects and the effect of the levels of composition. The result shows that the high components of the coefficient have low effect with high compression ratio in addition to high correlation factor. 108 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The World Wide Web contains large volumes of Web pages that are poorly characterized in terms of both metadata and structure descriptions. Metadata is the data that describe data, for Web pages, it may provide a significant amount of information about the Web without examining its content and serves a variety of purposes. At the other side, the search engine needs to scrape all Web pages of the target Website, when a new Web page is first available, it will typically take several days-for the page to be detected and indexed by the search engine. Until a page has been indexed, the users cannot find information about it on search engine results. This represents a time and resource-consuming operation and heavy network bandwidth consumption involved with the retrieval of the mark-up code of these Web pages which finally affects the users by increasing the time taken for new content or a content modification to be reflected in the search engines results. For instance, Web-related metadata can improve search efficiency and the quality of the search results. This thesis proposes an approach called Multilateral Web Indexing Model (MWIM), which aims to describe a solution to the previous. 152 pp. Englisch.

And the proventriculus of kite was larger than those of other two species. The duodenum in the three studied birds formed single loop while the ileum exhibited much interference loops and internally provided with longitudinal folds, there was no diverticuli vateline.The present histological examination differences that found in the gastrointestinal tract GIT of three species of birds dependent of type of the food.It can be concluded that the differencese in food type of birds have obvious effect in histological structure of digestive tract, especially, thickness of digestive tract layers. 192 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The era of digitization has paved the way for the emergence of multimedia technologies. The multimedia applications use a large video database. Applications such as video surveillance, traffic monitoring and live streaming of events need continuous monitoring of the video. Thus the video surveillance system for tracking multiple target objects from videos is one of the important research works. Video surveillance has many challenges such as inter-object occlusion, object confusion, different posing, environment with heavy clutter, the small size of objects, similar appearance among objects, and interaction among the multiple objects. The hybrid tracking model utilizes the spatial tracking model, based on the tangential weighed function and the visual tracking model based on the second derivative model. 188 pp. Englisch.
