Correlation of lipid profile and QT interval, T-wave changes as a risk factor for cardiovascular disease
G.V. Lathadevi,S. Anusha
International Journal of Pharmacy and Biomedical Sciences , 2012,
Abstract: Cardiovascular disease (CVD) remains the leading cause of death and disability worldwide. Dyslipidemia is an important risk factor for the initiation and progression of atherosclerosis and is strongly associated with cardiovascular events. Many studies in the past have established the value of lipid profile abnormalities and the ECG changes- QT interval prolongation and T wave inversion as markers of future adverse cardiovascular events. This study will try to establish if these two individual risk factors are associated with each other or not. It was a prospective, observational study conducted on 40 subjects of abnormal lipid profile compared to 40 control subjects both of whom were otherwise healthy. In the ECG, parameters like RR interval and heart rate, QT interval (QTi), Corrected QT interval (QTC), T wave changes (inversion) was calculated and noted, then compared with both the groups. By the independent sample‘t’ test, when compared to the control group, the group with abnormal lipid profile showed a significant QTi prolongation (by P<0.02) and a highly significant QTc prolongation (by P<0.001). However, T wave inversion did not show any significant presence in the test group as compared to the controls. Abnormal lipid profile has shown a consistent positive association with QT interval prolongation while no such association exists with T wave changes. Thus patients with an abnormal lipid profile are likely to be associated with an additional CVD risk of prolonged QTc. This compounds the risk of CVD in patients with any one of these individual factors and therefore the threshold for preventive therapy like lifestyle modification and/or preventive drug therapy like low dose aspirin must be lowered.

Abstract:

High-temperature superconductivity in ceramic oxides is a new technology in which advances are occurring at a rapid pace. Here, the author describes some properties of a new nano crystalline ceramic Type II superconductor, PbSrCaCuO. Type II superconductors are usually made of metal alloys or complex oxide ceramics. The PSCCO perovskite phase structure was prepared by the conventional solid state reaction technique. In order to show the viability of the proposed method, super-conducting powder was prepared in special furnace. The sample was analyzed by X-ray Diffraction (XRD), Particle size determination, SEM and EDX. The comparison of XRD results with JCPDS files confirmed the orthorhombic structure of the sample with a ≠ b ≠ c and α = β = γ = 90°. Scanning electron microscopy (SEM) studies revealed that its particle size is in the nanometer range. It also confirmed the calculated value of particle size from Debye Scherrer’s formula. EDX spectrum shows the elements of the sample. X-ray instrumental peak broadening analysis was used to evaluate the size and lattice strain by the Williamson-Hall Plot method.

International Journal of Engineering Trends and Technology , 2012,
Abstract: As the tax information system is service faced system in the past few years, there exists a lot of accumulated historical data where it can’t be modified. So, this system failed in tracking and monitoring to the changes of tax source. The data accumulated can be wasted and can’t be used properly at analyzing tax information. Today, the real challenge for tax agencies is to improve the tax collection process and to formulate optimized legislative polices to provide better taxpayer services. The existing Online Transaction Processing (OLTP) systems are not adequate to fulfill the need of complex tax collection analysis. And it is very difficult to come up with the optimized model. To make the best optimized model it has to be built around facts. It will be helpful to use a Tax Decision Support System to make strategic decisions. To solve this problem, this paper introduces the decision making activities and tax reduction methods for tax revenue. To maintain the effective tax management system, we are introducing data warehouse and OLAP techniques.

Abstract: A questionnaire was distributed to final year students at a single medical school in the UK to assess their exposure to and knowledge of renal transplantation.Although 46% of responding students had examined a transplant recipient, only 14% had ever witnessed the surgery. Worryingly, 9% of students believed that xenotransplantation commonly occurs in the UK and 35% were unable to name a single drug that a recipient may need to take.This survey demonstrates a lack of exposure to, and knowledge of, the field of renal transplantation. Recommendations to address the problems with the recruitment of surgeons and donation of organs, by targeting medical students are made.With the potential for improved quality of life and increased life expectancy, renal transplantation is the first choice treatment for most patients with end-stage renal failure [1,2]. However, in the UK there is an ever-increasing disparity between the number of patients on the waiting list and those being transplanted [3]. This is predominantly due to a rise in the incidence of renal failure amongst an aging, racially diverse society in conjunction with a shortage of donated organs [4].The field of renal transplantation also suffers from a lack of surgeons. Indeed, it is predicted that by the year 2005 there will a shortage of over twenty consultant renal transplant surgeons [5].Any measures to deal with these problems must include educating and attracting the doctors of tomorrow; medical students [6,7]. However, the General Medical Council's core curriculum model for undergraduate teaching has lead to significant changes in the way that specialist subjects are taught [8]. This survey was conducted to assess the exposure to, and knowledge of, renal transplantation amongst medical students at a single medical school in the United Kingdom.In July 2003 a PRHO job fair was held for final year medical students of Bristol University, which all 140 students within the year attended. An anonymous questionnaire

Abstract: In October 2004 a questionnaire was sent to the clinical deans of all UK medical schools regarding undergraduate exposure to renal transplantation.Twenty-five replies were received, giving a response rate of 96%. All but one school had a centre for renal transplantation in their region. Three schools (12%) gave no formal lecture or tutorial on the subject during the entire course. Of the remainder, between one to four formal sessions were provided, ranging from 15 minutes to 3 hours duration.Six medical schools (24%) provided no compulsory clinical exposure to renal transplantation, with a further five (20%) saying that students may receive exposure by chance. The average length of attachment was three weeks. Twenty-one medical schools (84%) provided between 1–10% of students a choice to study renal transplantation, as part of electives and special study modules.This study reveals a variation between, and within, medical schools in the levels of formal teaching. If the trends in recruitment to renal transplantation are to be reversed, we have an obligation to improve upon the medical education that students currently receive.Renal transplantation is the first choice treatment for many patients with end-stage renal failure, with the potential for improved quality of life and increased life expectancy [1,2]. However, in the UK, the speciality suffers from a lack of qualified surgeons with a predicted shortage, in 1999, of over twenty consultant renal transplant surgeons by the year 2005 [3]. The most recent figures have shown that of the 94 renal transplant consultant posts in the UK, 12 are filled by locums [4].Previous work has highlighted the multiple factors that deter surgical trainees from the speciality, which include a lack of exposure to the speciality, at an early stage during training [3]. This has lead to a call for the inclusion of transplantation within basic surgical training rotation programmes.Last year a crisis meeting, organised by the British Trans
Remote Procedures Calls Implementing using Distributed Algorithm

International Journal of Computer Technology and Applications , 2011,
Abstract: Remote Procedure Call (RPC) is a powerful primitive used for communication and synchronization between distributed processes. RPC poses a problem that it reduces the amount of parallelism, because of its synchronous nature. This paper shows how simple processes can be used to find a way of avoiding a difficulty in this problem. The combination of blocking RPC calls and light-weightprocesses provides both simple semantics and efficient exploitation of parallelism.We will describe how two important classes of algorithms, branch and bound can be run in a parallel way using this RPC. The results of some experiments comparing this algorithms on a single processor discussed

K.Anusha,Manohar Gosul,G. Dileep Kumar
International Journal on Computer Science and Engineering , 2012,
Abstract: Wireless Sensor Networks (WSNs) are widely used in applications like location monitoring, object tracking and decision making systems. Movement patterns of mobile sensor nodes play an important rolein such systems. This paper is aimed at simultaneous localization of mobile nodes. This is done based on RSSIs (Received Signal Strength Indicators) with correlated in time measurement noises. We proposed aframework with two multi model auxiliary particle filters. The first one is with a noise augmented state vector while the second one is to implement noise decorrelation. The performance of the proposedframework is validated using a simulator and the empirical results revealed that our framework provides high localization accuracy.

Abstract:
With the discovery of high-TC superconducting materials like Yttrium Barium Cupric Oxide, Bismuth Strontium Calcium Copper Oxide and Thallium Calcium Barium Copper Oxide, tremendous interest has developed over the past two years in understanding these materials as well as utilizing them in a variety of applications. The thin films of these materials are expected to play an important role in the area of microelectronics, especially for interconnects in integrated circuits, Josephson junctions, magnetic field sensors and optical detectors. Here, the authors designed a new nanocrystalline ceramic type II high-TC superconductor, Gadolinium Barium Copper Oxide (GdBaCuO/GBCO). The GBCO perovskite phase structure was prepared by the conventional solid state thermochemical reaction technique involving mixing, milling, calcination and sintering. In GBCO system, the method for controlling microstructure and superconducting state is related to oxygen content consideration because small changes in oxygen concentration can often lead to huge change in Tc. In order to show the viability of the proposed method, super-conducting powder was prepared in special furnace. The sample was analyzed by X-Ray Diffraction (XRD), an indispensible non-destructive tool for structural materials characterization and quality control which makes use of the Debye-Scherrer method. The comparison of XRD results with JCPDS files confirmed the orthorhombic structure of the sample. Micro-structural features are studied using Scanning Electron Microscopy (SEM) which revealed that its particle size is in the nanometer range. It also confirmed the calculated value of particle size from Debye Scherrer’s formula. EDX plot shows the presence of all the constituents. X-ray instrumental peak broadening analysis was used to evaluate the size and lattice strain by the Williamson-Hall Plot method.

Abstract: The high temperature superconductors are ceramic materials with layers of Copper-oxide spaced by layers containing Barium and other atoms. The Yttrium compound is somewhat unique in that it has a regular crystal structure while the Lanthanum version is classified as a solid solution. The Yttrium compound is often called the 1-2-3 superconductor because of the ratios of its constituents. Lanthanum Zirconium Yttrium Barium Calcium Copper Oxide (LaZrYBaCaCuO) was prepared by the usual solid state reaction method. In order to show the viability of the proposed method, super-conducting powder was prepared in special furnace. The sample was analyzed by X-ray Diffraction (XRD), Particle size determination, SEM and EDX. The comparison of XRD results with JCPDS files confirmed the orthorhombic structure of the sample with a ≠ b ≠ c and α = β = γ = 90°. Scanning Electron Microscopy (SEM) studies revealed that its particle size is in the nanometer range. It also confirmed the calculated value of particle size from Debye Scherrer’s formula. EDX spectrum shows the elements of the sample. X-ray instrumental peak broadening analysis was used to evaluate the size and lattice strain by the Williamson-Hall Plot method.

Abstract: X-ray crystallography is concerned with discovering and describing the crystal structure. High-temperature superconductivity in ceramic oxides is a new technology in which advances are occurring at a rapid pace. Here, the author describes some properties of a new nano crystalline ceramic type II superconductor, PbBaTiO. Type II superconductors are usually made of metal alloys or complex oxide ceramics. The PBT perovskite phase structure was prepared by the conventional solid state reaction technique. The sample was analyzed by X-ray Diffraction (XRD), Particle size determination, SEM and EDX. The comparison of XRD results with JCPDS files confirmed the tetragonal structure of the sample with a = b ≠ c and α = β = γ = 90°. Scanning electron microscopy (SEM) studies revealed that its particle size was in the nanometer range. It also confirmed the calculated value of particle size from Debye Scherrer’s formula. EDX spectrum shows the elements of the sample. X-ray instrumental peak broadening analysis was used to evaluate the size and lattice strain by the Williamson-Hall Plot method.
