Helicobacter pylori: The association between CagA positivity and p53 expression[ ]


H. pylori had been recognized as the causative agent of several gastric diseases and possessed wide variety of virulence factors, one of most important factors is CagA. p53 have central role in many cellular activities, one of them is the apoptosis. This study investigated the expression of p53 in the gastric epithelial cells in patients with Helicobacter pylori gastric illness in association with CagA positivity. Paraffin embedded tissue had been made form biopsies taken from 30 patients undergo O.G.D. and selected according to exclusion criteria. In addition, 10 apparently healthy volunteers were included as a control group. Procedures of ISH and IHC were used to detect CagA and p53 respectively. The CagA cytotoxin was detected in 21(70.0%) patients out of 30 and 9 (30.0%) gave negative results, p53 immunostaining shows 26/30 cases strong staining and 4/30 cases gave a moderate staining. The CagA positive H. pylori strains causes a higher p53 expression than the CagA negative strains.

General Analytical Solution for Estimating the Elastic Deformation of an Open Borehole Wall[ ]


Few analytical solutions have been published in the past decades for quantifying the ballooning volume caused by elastic deformation of an open borehole; nevertheless none of them takes into consideration the effects of permeability and thermoelasticity. This paper introduces new analytical solutions aiming at predicting a radial elastic displacement for any point along an open borehole wall. The presented analytical formulas here are general and taking into account the effective stresses, thermoelasticity and the poroelasticity effects. Two analytical formulas are derived, one for impermeable borehole, whereas the second is for permeable borehole. To utilize the proposed analytical solution for estimation the volumetric expansion and contraction of an open borehole, a recognized mathematical method has been adapted to be used for defining the areal elastic deformation of an open borehole at a given depth, which later can be used to quantify the volumetric change of an open borehole for specified depth interval. In order to validate the proposed formulas a finite element simulation was utilized. Several cases have been examined and compared, generally good results were observed with relative error less than 15%. Finally, results of a sensitivity study which was performed in order to assess the effects of different parameters on volumetric deformation of the open borehole are presented and discussed in details, the main finding of this study was that the deformation area of the borehole due to the elastic deformation is not significant and controlled mainly by the wellbore pressure.

Sensitivity and specifity of multifocal and full-field electroretinography in diabetic retinopathy[ ]


Non-invasive recordings of the retinal activity have an important role in the diagnosis of retinal pathologies and in defining the state of retina. The current study described the responses of F-ERG and MF-ERG in patients with diabetic retinopathy (DR) compared to normal subjects, to establish whether there were differences in MF-ERG first order response among normal, NPDR, and PDR eyes, to correlate their results in detecting dysfunction in patients with diabetic retinopathy and to determine their sensitivity and specificity. Twenty patients with DR and 20 eyes of 10 normal subjects were examined using MF-ERG and F- ERG. The latencies and amplitudes were measured, recorded and compared among the three groups. The mean and standard deviation (SD) were evaluated using statistical package for social science (SPSS.15). Receiver operator characteristic (ROC) curves were constructed to determine the sensitivity and specificity of abnormal values in patients compared to the normal controls.The results of this study showed that Diabetic retinopathy (DR) markedly affected on all parameters of MF-ERG. The response densities of MF-ERG were decreased and latencies of p-wave were prolonged. The MF-ERG responses obtained from eyes with DR were significantly different (P > 0.05) from those of normal eyes.in F-ERG latencies of a-waves photopic response and 30HZflicker were not different among the groups. In DR significant correlation found between ring 5 and standard combined response amplitudes and latencies and also with cone response. In non-proliferative diabetic retinopathy, the areas under ROC curves (AUCs) were larger for the MF-ERG (0.648 to 0.857) than those for the F-ERG ( 0.457 to0.573) which means that MF-ERG responses yielded greater sensitivity and specificity than F-ERG. In proliferative diabetic retinopathy, there was no difference in the AUCs and sensitivities between MF-ERG and F-ERG.

Practical Steps in the Design and Analysis of an efficient Off-Grid Solar Power System for Homes: Panacea for the Lingering National Energy Crises[ ]


The possibility of employing photovoltaic system in the generation of large and ‘clean’ Electrical Energy to power, at least, homes has generated a whole lot of global interest in the recent past. In the Nigerian situation, it can be a veritable panacea for her continued raging National Energy crises. It is common knowledge that the Power Holding Company of Nigeria has not been able to power industries and cities effectively, not to talk of rural areas. This prevailing abysmal energy situation has thus imposed great constrain in the rapid socio-economic development and transformation of the Nation, and the rural areas in particular, as envisaged in the Millennium Development Declaration. This paper discusses practical steps that may be taken in the design and installation of efficient off-grid solar power system for homes, as a way of reducing, if not ending, the lingering National Energy Crises.

Magnetohydrodynamic Couette Flow Of A Non-Newtonian Fluid In A Rotating System With Heat And Mass Transfer[ ]


An analytical solution is obtained for the steady Couette flow of an electrically conducting fluid between two parallel plates when the fluid and the plates rotate in unison about an axis normal to the plates. The equations of motion and energy have been solved with the help of complex variable technique pertaining to the imposed boundary conditions. After necessary computation with the various numerical values of the fluid parameters the expressions for primary velocity, secondary velocity of flow and temperature have been obtained. Then, the expressions for shear stresses and the rates of heat transfer have been derived. The results obtained are discussed with the help of graphs and tables to observe the effects of various parameters. It has been found that the primary velocity decreases with the increase of rotation parameter whereas the secondary velocity rises in reverse direction. The increase in the value of Prandtl number increases the rate of heat transfer at the stationary plate but reduces at the moving plate. These results are in good agreement with earlier results.

Rainfall prediction in Nigeria using Artificial Neural Networks[ ]


Rainfall data from the Nigerian Meteorological Agency, Oshodi, Lagos collected over thirty (30) years and from twenty three weather measuring stations spread across Nigeria have been used for the study. By applying stochastic and data reduction procedures the data was filtered to fast track the actual variables to be used for modeling rainfall. There were a total of 360 monthly mean data points for each station. The first 300 data points representing 25 years were used for training the network. The remaining 60 data points representing 5 years were used to cross validate the model. Each set of data was trained for 5 different sets of epochs. The number of epochs was chosen at intervals of about 500, 1000, 1500 2000 and 3000 epochs. By varying the weights and learning cycles, 5 different sets of predicted values were obtained. The predicted values were then correlated with actual values for corresponding periods. We obtained correlation coefficients between measured and predicted values up to 0.80 with an average value of 0.56. Compared on latitudinal basis, the coefficients were in ascending order from south to North. This means that the predictability of rainfall using Neuro Xl was better at higher latitudes.

Multi Tenancy Access Control Using Cloud Service in MVC[ ]


Cloud Computing is the next generation Internet service and data center, and it is also used for public utilities and on-demand computing. Cloud computing is not a totally new technology, but rather a derived concept of application and service innovation in which, multi-tenancy is one of the important issues among the core technologies of cloud computing applications. Many tenants can access the different applications and computing resources in the same cloud server, whereas concurrent use by many users on a database or application will lead to large data volume, time consuming and security issues. Under these circumstances, it is particularly important to separate application and data for conflicts avoidance to enhance the system and data security. This paper emphasizes the cloud service model under a Multi-Tenant Architecture (MTA), using identity management and Role Based Access Control, to propose a Design Security Multi-Tenancy Access Control (DS-MTAC).The DS-MTAC applies identity management to determine the user’s identity and applicable roles, since different users possess different functional roles with respective privileges for processing. Such role-based assignments can easily and efficiently manage a user’s access rights to achieve application independence and data isolation for improving the processing performance of cloud multi-tenant services and hardening the security and privacy of cloud applications

Improvement of the Voltage Quality of Hyderabad Network in India[ ]


In this paper the performance of the electrical network of India is studied by considering a small part on the network (Hyderabad city). The transmission network of Hyderabad city was created for 220 kv, 132 kv, 33 kv and 11 kv in the digital simulation and electrical network calculation (DIgSILENT Power Factory Software) to study the voltage profiles. The load flow operational analysis was performed to obtain the voltage magnitudes at every bus bar. The voltage magnitudes in 33 kv and 11 kv networks were 10% to 15% less than the nominal value due to overloading of the transmission lines and the voltage magnitudes in 132 kv and 220 kv were within permissible limits. By using automatic tap-changing transformer or Static VAR System, the main idea of this paper is to obtain the voltage profiles at every bus bar to improve the voltage quality of the networks, so as to achieve better voltage profiles on the low voltage side without much affecting high voltage side under various operating conditions.

Detection and virulence of Ralstonia solanacearum the causal of potato brown rot disease[ ]


This work aimed to detect and determine the virulence in addition to the host range of Ralstonia solanacearum the causal of potato brown rot disease. Isolation from naturally infected potato tubers of three different cvs. (Spunta, Draga and Nicola) showing brown rot disease symptoms revealed that all isolated bacteria showed typical morphological growth of R. solanacearum on SMSA medium where; colonies were fluidal white with red center. Also, IFAS test (Immunoflurescence Microscope Antibody Staining) confirmed that these isolated bacteria are R. solanacearum. The traditional identification of the three tested pathogenic bacteria isolates exhibited similarity among them based on their cultural and morphological characteristics where, these isolates were non-sporulating short rods with weak Gram negative reaction. Also, their developed colonies on nutrient agar (NA) medium were irregularly/round, convex, smooth surface, entire margin, translucent and yellowish brown in colour. Meantime, these colonies were whitish-gray in colour on King’s B (KB) medium forming brown pigments in most cases. Also, the physiological and biochemical tests of the three bacterial isolates showed oxidative metabolism of glucose and positive results with oxidase reaction, catalase reduction, H2S production, nitrate reduction. However, the three isolates were negative to Indole production, gelatin liquefaction, Arginine dihydrolase, starch hydrolysis, Voges proskauer test and Levan formation. Also, the three tested isolates of R. solanacearum showed virulence against potato and tomato plants. While, these isolates were avirulent to eggplant, pepper, tobacco and banana plants under artificial inoculation conditions which reveal that theses isolates belong to race 3. Also, all three tested isolates utilized maltose, lactose, cellobiose and glucose but not oxidized mannitol, sorbitol and dulcitol. As for virulence of the three tested R. solanacearum isolates, results exhibited different percentages of disease severity on potato plants (cv.Nicola) at 15 days of incubation period. Also, Draga- isolate was the fastest one followed by Nicola -isolate. Draga-isolate of R. solanacearum infected many hosts with different degrees of wilt severity where it was virulent to tomato, mallow, datura and little hogweed. Also, positive results were obtained with SMSA, IF and PCR techniques to confirm the infection with Draga-isolate.
