Perturbation Solution for Thermal Diffusion and Chemical reaction Effects on MHD Flow in Vertical Surface with Heat Generation
A study two-dimensional laminar incompressible flow continuously moving vertical surface porous plate has been analyzed to show the effect of an additional cross transport phenomenon, i.e. heat flux caused by concentration gradient in addition to the heat flux caused by temperature gradient. Further thermal Diffusion and chemical reaction effects on MHD flow in vertical surface with heat generation has been taken into consideration in the present study. Moreover, the Dufour effect has been considered in energy equation leaving the equation of thermal diffusion and mass diffusion coupled. The coupled non-linear equations are solved by applying perturbation technique. The effect of flow parameters are shown with the help of graphs
An Automated Approach of Detection of Memory Leaks for Remote Server Controllers
Memory leaks are a major concern to the long running applications like servers which make the working set to grow with the program. This eventually leads to system crashing. This paper discusses a staged approach to detect leaks in firmware of remote server controller. Remote server controller monitors the server remotely with many processes running in the background. Any memory leak in the long running applications pose a threat to the performance of the system. The approach adopted here filters the processes running in the system with leaks based on time threshold in the first stage. These processes with leaks are passed to the next stage where precise memory leak detection is done using the open source dynamic instrumentation tool Valgrind. The system leverages an automated leak detection approach that invokes the leak detection process on encountering any severity in the system and generates a consolidated leak report. The proposed approach has less impact on the performance of the system and is faster compared to many available systems as there is no need to modify or re-compile the program. In addition, the automated approach offers an effective technique for detecting possible leakages in early software development phases

The diagnostic significance of hyperfibrinogenemia and thrombocytosis in patients with ovarian tumors/adnexal masses
Background: We aim to study the correlation of thrombocytosis and hyperfibrinogenemia with ovarian tumors and its role in the diagnosis of ovarian malignancy. And to evaluate the platelet and fibrinogen levels in early and advanced stage ovarian disease.
Methods: This is a single centre prospective study. We evaluated plasma fibrinogen levels and plasma platelet levels in 250 patients in women presenting in our OPD with adnexal masses/ovarian tumors. Thrombocytosis was defined as a platelet count greater than >410,000/uL. Hyperfibrinogenemia was defined as a fibrinogen level higher than 360 mg/dL. The association between plasma fibrinogen, platelet levels and clinico-pathological, histopathological parameters were investigated in regards to: 1. Malignant or benign ovarian tumor. 2. Early or advanced disease in malignant ovarian tumors. A multivariate logistic regression model was performed to identify an independent association.
Results: Thrombocytosis and hyperfibrinogenemia are seen to be associated with malignant ovarian tumors. In a multivariate model, plasma fibrinogen and plasma platelet levels were identified to be independently associated with the malignant ovarian tumours. Within the EOC cohort, patients with advanced stage disease had higher plasma fibrinogen levels than patients with early stage.
Conclusions: In this study, we demonstrated that both thrombocytosis and hyperfibrinogenemia were positively associated with malignant ovarian tumors. They were also associated with advanced disease stage, elevated CA125 level and other markers. These finding are in accordance with the previous published data from patients with ovarian cancer, indicating that the platelet and fibrinogen levels increase in parallel with tumor progression and metastasis. Thus confirming the role of elevated platelet and fibrinogen levels in diagnosis and prognosis of ovarian Malignancy
OPTIMIZATION OF CULTURE CONDITIONS OF STREPTOMYCES CARPATICUS (MTCC-11062) FOR THE PRODUCTION OF ANTIMICROBIAL COMPOUND
Objective: To improve the antimicrobial compound productivity of Streptomyces carpaticus (MTCC-11062) by optimizing its physical and chemical parameters
Methods: Streptomyces carpaticus (MTCC-11062) was isolated from Visakhapatnam sea coast of Bay of Bengal and was screened for its antimicrobial activity by using agar well diffusion method. To improve the production of antimicrobial compound the medium composition and physical parameters were optimized and its productivity was studied against Bacillus cereus (MTCC 430) Escherichia coli (MTCC 443), Candida albicans (MTCC 227) obtained from MTCC, Chandigarh, India.
Results: Optimum growth of mycelium and antimicrobial compound production occurred at pH 7.2, agitation 180 rpm and temperature 300C with glucose 10g/L, soyabean meal 2.5g/L, K2HPO4 2g/L, MgSO4 1g/L, NaCl 7.5g/L and trace salts.
Conclusion: The optimization of cultural conditions proposed in this paper has effetely improved the antimicrobial compound productivity of Streptomyces carpaticus (MTCC-11062)
FORMULATION AND CHARACTERIZATION OF SUSTAINED RELEASE MATRIX TABLETS OF IVABRADINE USING 32 FULL FACTORIAL DESIGN
Objective: Ivabradine (IB) is anti-Ischemic drug and used for the symptomatic management of stable angina pectoris. IB acts by reducing the heart rate in a mechanism different from beta blockers and calcium channel blockers, two commonly prescribed anti-anginal drugs. IB has a short biological half-life and the dose of 5/7.5 mg twice a day. In this present study, an attempt has been made to prepare sustained release tablet of IB to achieve the desired drug release.Methods: The sustained release polymers, hydroxypropyl methylcellulose K100M (HPMC K100M), guar gum (GG) and xanthan gum (XG) were taken for the preliminary trail from which guar gum and xanthan gum had shown better drug release. Initially, drug-excipients compatibility studies were carried out by using Fourier transformed infrared spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC) which showed no interaction between drug and excipients. Tablets were prepared by wet granulation technique and evaluated for pre-compression and post-compression parameters.Results: 32 full factorial design was applied to achieve controlled drug release up to 24 h. The concentration of GG (X1) and XG (X2) were selected as independent variables and the % CDR at 2 h. (Y1) and 18 h. (Y2) were taken as dependent variables. In vitro drug release study revealed that as the amount of polymers increased, % CDR decreased.Conclusion: Contour as well as response surface plots were constructed to show the effect of X1 and X2 on % CDR and predicted at the concentration of independent variables X1 (10 mg) and X2 (10 mg) for a maximized response. The optimized batch (O1) was kept for stability study at 40±2 °C/75±5 %RH for a period of 6mo according to ICH guidelines and found to be stable
