This research highlights the significance of preventing, finding out and treating diabetes mellitus (DM) from early stages of on set. The late finding of diabetes mellitus leads to both medical and economic losses. The treatment of the complications of the diabetic disease raises the costs of the care and the losses due to patient missing from work cannot be neglected. The expenses with diabetes mellitus have constantly increased everywhere in the world. The highest costs for a diabetic patient raised to 13,243 USD/patient/year, in 2002, in the USA – the highest ever recorded costs of this disease. The estimations made by International Diabetes Federation show that, in 2012, the cost for diabetic patients care reached 471 billion USD, in the world, and 138.8 billion USD, in Europe. A study carried out in Europe in 2008, showed that hospitalization costs represent almost 60% of the total costs of diabetes mellitus treatment, outpatient care costs 18.5% and drug therapy represents 21.7%. In Romania, the treatment of diabetes mellitus is free of charge. The funds allotted by the Ministry of Health for the Diabetes Programe in the time interval 1999-2012 increased 25 times, but Romania ranks among the top ten countries with diabetes cases in Europe.
In order to better understand how to prevent enzymatic greenning, it is important to\nunderstand kinetic properties of polyphenol oxidase. vegetable markets projected for the\nfuture will not occur if enzymatic greenning is not understood and controlled. We\ninvestigated the effect of SDS on the rate of catechol oxidation by wild pears partial\npurified PPO. PPO activity increased with increasing SDS concentration. The most\neffective concentration of SDS was 0.9 and 1 mM in according to pH and type of\nsubstrate, where the measured activity was 782 and 3200 units/mg.protein at pH 5 and\n380 and 1100 unit/mg.protei.n at pH 7 for catechol and pyrogallol, respectively at 1 mM\nSDS. The activation of pears PPO increased linearly with the SDS concentration up to 1\nmM and decreased thereafter. The activity of pear PPO was also enhanced 2.6-fold by\nexposure to SDS at pH 5.0 in presence of catechol, 3.7-fold by exposure to SDS at pH\n5.0 in presence of pyrogallol, 1.7-fold by exposure to SDS at pH 7 in presence of catechol\nand 1.7-fold by exposure to SDS at pH 5 in presence of pyrogallol. SDS has activating\neffect on polyphenol oxidase in presence of both dihydroxy and trihydroxy phenols, So\nthat, this activating effect at pH 5 is more than activating effect at pH 7.
Abstract:\nThe vast and growing need of society to the building and housing has raised the necessity of using construction systems and new construction materials in order to accelerate construction operation, reduce construction cost, increase quality and also retrofitting and strengthening buildings resistant against earthquake more than before.Due to the relatively vast geographical area of the developing country of Iran, and given the rapid burgeoning population and growing requirements to mass housing production, common and traditional construction methods utilization cannot meet the housing requests. So, application of modern technologies and/or construction methods by using industrial production methods is the proper response for the challenges facing the building industry of the country.

Teleradiology facilitates timely interpretation of medical images for better medical care. Observations at the referral site can help the remote radiologists make a thorough analysis. Images transferred to remote sites must be accompanied with relevant patient identifiable data to resolve identity issues when similar images are to be examined by a radiologist. In this paper, we present a zero-watermarking scheme to watermark a host image, with a Health Level 7 (HL7) message encompassing patient identifiable data and clinical readings that is encoded into a binary Quick Response (QR) code. The proposed system preserves the fidelity of the cover image as the watermark is not physically embedded. Embedding and extraction are realized with a Master Share, Secret Share and a binary QR code. In the proposed system, Master Share is created out of the sign bit sequence of the Hu’s moments, computed on selected non overlapping blocks of the host image subjected to Singular Value Decomposition (SVD). Robustness to geometric and non geometric attacks is evaluated by running attacks with different parameters with a benchmarking software. The proposed system exhibits security and robustness characteristics essential to deliver teleradiology practices in compliance with legislative standards.
Removal of Al3+ and Mn2+ from solution by Trichoderma asperellum BHU216 immobilized on Irvingia gabonensis matrix in a batch system was investigated. Effect of biosorption conditions contact time, pH, bead size and spore load were studied. Equilibrium isotherms and re-usability of biosorbent were also determined. The result showed that optimum sorption of Mn2+ and Al3+ by immobilized sorbent was achieved at 7 mm bead size and 1.6 g/L spore load. Optimum pH were 5 and 6 while equilibrium was attained at 120 and 180 mins for Mn2+ and Al3+ sorption respectively. Immobilized biosorbent was used in more than 5 batch cycles with over 50% removal achieved in 3 and 5 cycles for Al3+ and Mn2+ sorption. Brunauer-Emmett-Teller (BET) isotherm had the best-fit than both Langmuir and Freundlich isotherms for both metals (R2 0.99 and 0.97 for Mn2+ and Al3+ respectively). Manganese sorption proceeded at both surface and multi-layer levels with high sorption rates 18.88 mg/L and 19.72 mg/L, while aluminium sorption was feasible in a multi-layer process with low uptake (0.87 mg/g). This study showed that immobilized T. asperellum BHU216 can effectively act as biosorbent for Mn(II) and Al(III) sorption from solution.
Abstract: \n\nInflatable rubber dams are cylindrical rubber fabrics placed across channels, streams and weir or dam crests to raise the upstream water level when inflated. Inflatable dams can be filled with water, air or both. In this paper, an analytical model is presented for hydrostatic analysis of the dam. The model has been made and the results are compared with Alhamati et al experimental results. There is an acceptable similarity in both numerical and experimental behavior of the dam.
Abstract:\n In most of the current design codes and standards for concrete liquid storage tanks, the hydrodynamic pressures are determined assuming that the tank walls are rigid. The Housner’s model, which assumes that the mass of liquid is lumped on the wall based on rigid wall boundary condition in the calculation hydrodynamic pressure, is widely used in practice. Previous research has indicated that the flexibility of wall can affect the distribution and magnitude of hydrodynamic pressures. In this paper, the effect of wall flexibility on hydrodynamic pressures in concrete rectangular tanks is studied using an approach referred to as the sequential method. The procedure on how to establish the impulsive hydrodynamic pressures using the sequential method based on a two-dimensional analysis is described. A comparison shows that the lumped mass approach overestimates the base shear and wall displacements.
