International Journal of Pharmaceutical and Biomedical Research (IJPBR) , 2012,
Abstract: Objectives: To assess the usefulness of high resolution computed tomography scan in the detection and characterization of pulmonary infections in patients with febrile neutropenia.Material and Methods: Seventy five (75) patients with febrile neutropenia admitted in different ward of a tertiary care hospital were selected for the study. A detailed history regarding pulmonary symptoms and background illnesses was taken followed by detailed clinical examination and basic investigations like complete haemogram and chest X-ray (PAview). HRCT scan of thorax was done in each patient for detection of any pulmonary lesion and characterization of the lesion, if present. Final diagnosis was reached on the basis of sputum, blood, bronchoalveolar lavage or transbronchial biopsy examinations and/or clinical response to a particular antibiotic /antifungal agent.Results: Mean age of the patients was 14 to 71 years. Commonest symptoms were fever (100%) followed by dyspnoea (32%) and cough (24%). Chest X-ray could detect pulmonary abnormalities in 21(28%) cases and could characterize the lesion in 2(2.7%) cases only. HRCT thorax could detect pulmonary abnormalities in 69(92%) cases and could correctly characterize the lesions in 86% cases. Consolidation, ground glass opacity and nodules are predominant findings on HRCT in febrile neutropenic patients. Though considerable overlap existed, consolidation was commonly found in pyogenic infection, nodules with surrounding ground glass opacity in fungal infection and ground glass opacity in pneumocystis jiroveci infection. The sensitivity of HRCT in diagnosis of pyogenic, fungal, tuberculosis and pneumocystis jiroveci pneumonia was 83.33%, 92.8%, 78% and 88.89%, respectively. The specificity of HRCT in diagnosis of these infections was 88.5%, 86.26%, 94.72% and 81.12% respectively.Conclusion: HRCT can detect almost all types of infections in patients with febrile neutropenia with high sensitivity and specificity. Therapy can be started on the basis of HRCT findings even before the laboratory confirmation of infections in a significant number of cases. HRCT should be done in all febrile neutropenic patients to detect pulmonary focus of infection and to characterize the lesions for specific management.

International Journal of Pharmaceutical and Biomedical Research (IJPBR) , 2012,
Abstract: Purpose of this study was to evaluate the efficacy of sonourethrography (SUG) in detection and evaluation of anterior urethral strictures in male compared with retrograde urethrography (RUG). 50 male patients with clinically suspected benign anterior urethral stricture were subjected to RUG followed by SUG performed independently by different observer and subsequently correlated with operative findings. 50 patients with a diagnosis of urethral stricture were evaluated. Short segment, intermediate and long segment urethral stricture were detected were detected by RUG in 13,17,10 patients respectively as compared to 15,18,13 patients by SUG respectively. Sensitivity for detection of short, intermediate and long segment stricture with sonourethrography was 100%, 90.9%; & 88.2% respectively as compared to 88.23%; 83.3%, & 65.2% respectively on retrograde urethrography. Apart from stricture, mucosal, submucosal and periurethral soft tissue abnormalities could be followed up by sonourethrography as compared to retrograde urethrography. Mucosal abnormalities could be detected by SUG in 30% cases as compared to 10% by RUG, submucosal abnormalities were detected in 18% by SUG as opposed to none in RUG & spongiofibrosis was detected in 50% of case by SUG as opposed to none by RUG. SUG could detect diverticulas in 14% as against 8% by RUG and false tract in 6% cases by SUG as against 2% by SUG. Sonourethrography is highly sensitive for and accurate predictor of anterior urathral stricture for the detection of site and length of stricture for planning surgery and should be preferred diagnostic procedure. Retrograde urethrography underestimated the length of stricture in most of the cases. In addition, periurethral soft tissues can be well assessed by sonourethrography.

Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.48A017
Abstract:

An exact scalar field cosmological model is constructed from the exact solution of the field equations. The solutions are exact and no approximation like slow roll is used. The model gives inflation, solves horizon and flatness problems. The model also gives a satisfactory estimate of present vacuum energy density as well as vacuum energy density at Planck epoch and solves cosmological constant problem of 120 orders of magnitude discrepancy of vacuum energy density. Further, this model predicts existence of dark matter/energy and gives an extremely accurate estimate of present energy density of dark matter and energy. Along with explanations of graceful exit, radiation era, matter domination, this model also indicates the reason for present accelerated state of the universe. In this work a method is shown following which one can construct an infinite number of exact scalar field inflationary cosmological models.

GA Based Test Case Generation Approach for Formation of Efficient Set of Dynamic Slices
Debasis Mohapatra
International Journal on Computer Science and Engineering , 2011,
Abstract: Automated test case generation is an efficient approach for software testing. Slicing of program provides ease to testability and enhances debugging capacity. To generate the dynamic slice, slicing criterionis required in which the input data parameter is the essential component. Most of the research work focuses on deriving the input by random consideration but it simply takes a longest period of time to generate slices that provides the path coverage of Unit Under Test (UUT). This paper generates the optimal test cases by using Genetic Algorithm (GA) and Control Flow Graph (CFG), these test cases cover all the independent path present in the CFG. The optimal test cases are supplied as input component of the dynamic slicing criteria. So the dynamic slice criteria that use these optimal test cases as the input generates the efficient dynamic slice set that is helpful in efficient testing and efficient debugging. Here two approaches, first the dynamic slice using node marking and the second by using relevant sets are discussed according to optimal test cases as input component.

Abstract: In this paper we address the problem related to determination of the most suitable candidates for an M&A (Merger & Acquisition) scenario of Banks/Financial Institutions. During the pre-merger period of an M&A, a number of candidates may be available to undergo the Merger/Acquisition, but all of them may not be suitable. The normal practice is to carry out a due diligence exercise to identify the candidates that should lead to optimum increase in shareholder value and customer satisfaction, post-merger. The due diligence ought to be able to determine those candidates that are unsuitable for merger, those candidates that are relatively suitable, and those that are most suitable. Towards achieving the above objective, we propose a Fuzzy Data Mining Framework wherein Fuzzy Cluster Analysis concept is used for advisability of merger of two banks and other Financial Institutions. Subsequently, we propose orchestration/composition of business processes of two banks into consolidated business process during Merger & Acquisition (M&A) scenario. Our paper discusses modeling of individual business process with UML, and the consolidation of the individual business process models by means of our proposed Knowledge Based approach.

Journal of Quantum Information Science (JQIS) , 2012, DOI: 10.4236/jqis.2012.23015
Abstract: The entanglement of a pure bipartite state is uniquely measured by the von-Neumann entropy of its reduced density matrices. Though it cannot specify all the non-local characteristics of pure entangled states. It was proven that for every possible value of entanglement of a bipartite system, there exists an infinite number of equally entangled pure states, not comparable(satisfies Nielsen’s criteria) to each other. In this work, we investigate other correlation measures of pure bipartite states that are able to differentiate the quantum correlations of the states with entropy of entanglement. In Schmidt rank 3, we consider the whole set of states having same entanglement and compare how minutely such states can be distinguished by other correlation measures. Then for different values of entanglement we compare the sets of states belonging to the same entanglement and also investigate the graphs of different correlation measures. We extend our search to Schmidt rank 4 and 5 also.

BMC Plant Biology , 2003, DOI: 10.1186/1471-2229-3-5
Abstract: Mature embryo-derived calli of bread wheat (Triticum aestivum, cv. CPAN1676) and durum wheat (T. durum, cv. PDW215) were double bombarded with 1.1 gold microprojectiles coated with pDM302 and pAct1-F at a target distance of 6 cm. Southern analysis using the bar gene as a probe revealed the integration of transgenes in the T0 transformants. The bar gene was active in both T0 and T1 generations as evidenced by phosphinothricin leaf paint assay. Approximately 30% and 33% primary transformants of T. aestivum and T. durum, respectively, were fertile. The transmission of bar gene to T1 progeny was demonstrated by PCR analysis of germinated seedlings with primers specific to the bar gene.The transformation frequency obtained was 8.56% with T. aestivum and 10% with T. durum. The optimized protocol was subsequently used for the introduction of the barley gene encoding a late embryogenesis abundant protein (HVA1) in T. aestivum and T. durum. The presence of the HVA1 transgene was confirmed by Southern analysis in the T0 generation in case of Triticum aestivum, and T0 and T1 generation in Triticum durum.Wheat is one of the most abundant sources of energy and nourishment for mankind. Ninety-five percent of the cultivated wheat is of the hexaploid type used for the preparation of bread and other baked products and the remaining 5% is durum (tetraploid) wheat, which is used essentially for making pasta and macaroni (see [4]). Although stable transformation of wheat has been achieved with either co-cultivation with the natural plant genetic engineer Agrobacterium tumefaciens or particle bombardment, particle bombardment is emerging as the method of choice for introduction of agronomically important genes for quality improvement, molecular pharming, engineering of nuclear male sterility, transposon tagging, resistance to drought stress, fungal pathogens, and insect pests (for details see, [27]).Till date, most of the studies on wheat transformation have focussed on few model cultiv
