Corrosion investigation of nickel base superalloys in simulated high level waste medium using electrochemical impedance spectroscopy

67-72Nickel base superalloys (Alloy 600, 690 and 693) under as-received and heat treated (solution-annealed and sensitized) condition have been assessed by electrochemical impedance spectroscopic technique for their corrosion behavior in 3 M HNO3 and simulated high level waste medium at 25°C. All the alloys in all the conditions (as-received, solution-annealed and sensitized) show higher polarization resistance in 3 M HNO3 compared to simulated high level waste. The solution-annealed specimens for Alloy 690 and Alloy 693 show near capacitive behaviour in a larger ranger of frequency. Among the three alloys, Alloy 690 show highest polarization resistance followed by Alloy 693 and Alloy 600, due to the better stability of passive oxide layer. In contrast, the decreased polarization resistance for Alloy 600 specimens imply deterioration or reduction in the passive film stability

A rare case of Guillain-Barré syndrome in pregnancy and its implications: a case report

Guillain barre syndrome (GBS) is a rare neurological disease in pregnancy. Incidence varies from 1.2 and 1.9 cases per 100,000 people annually. It carries high maternal risk and may complicate pregnancy. It usually presents as an acute ascending symmetrical polyneuropathy. It requires early diagnosis and multidisciplinary supportive care for its management.

Management of Bacterial Wilt of Tomato Caused by Ralstonia solanacearum (Smith) Yabuuchi et al Using Biological Control Agents

Biological control agents, Glomus mosseae IIHR, Bacillus subtilis IIHR-1, Pseudomonas fluorescens IIHR+3, Trichoderma harzianum IIHR P1 and T. viride IIHR P22 were evaluated against tomato wilt caused by Ralstonia solanacearum in pathogen-infested plots during 2003-2004. Microbial preparations were applied either as transplant root dips or root dip plus soil drench 30 days after transplanting. Per cent survivability increased with the use of all biological control agents tested. However, G. mosseae treated plants resulted in better survival (25.75 and 28.79% in root dip alone and 60 and 66.67% in root dip plus drench against untreated control 0 and 1.5% during 2003 and 2004 respectively), compared to the rest of the treatments, suggesting G. mosseae amendment to pathogen-infested soil would result in substantially higher plant survival against the untreated controls

A very brief description of the fusion13; scheme in which the UD filtering algorithms are being used is given

Study of parameters of CSR-2 cocoon reared with V1 mulberry leaves irrigated by spentwash

CSR-2 silkworm reared with V1 variety of mulberry plants irrigated by raw water,50% PTSW and 33% PTSW. The different parameters such as raw silk (%), filamentlength (m), reelability (%), denier and shell ratio were determined at the maturity ofcocoons. It was found that the parameters werebetter in cocoon irrigated with 33%PTSWcompared to 50%PTSW and raw water irrigations. This concludes that the mulberryplants irrigated with 33%PTSW is enriched with more nutrients for the potential growthof mulberry plants which results in the potential cocoons

ACTINOMYCIN “D” FROM MARINE SEDIMENT ASSOCIATED STREPTOMYCES CAPILLISPIRALIS MTCC10471

In our screening program for new bio-active metabolites from marine actinomycetes, a cyclic depsipeptide wasfound in the fermentation medium of marine Strepromyces (SS23/4) isolated from sediments collected from Bayoff Bengal, vellampattai,Tamilnadu. It showed strong biological activity against gram-positive / gram negativebacteria by agar overlay technique. It was taxonomically characterized by the basis of morphological andphenotypic characteristics, genotypic data and phylogenetic showing Streptomyces sps. Bio active compoundwas obtained by solvent extraction and purification using column chromatography followed by reverse phaseHPLC. The pure compound had potent activity against Mycobacterium tuberculosis and Multi Drug ResistantMycobacterium tuberculosis strains (437RU) at a concentration of 10 μg/mL, and The minimum inhibitoryconcentration (MIC) against standard test organisms was found to be 1μg/mL against B.subtilis, E.coli andMethicillin resistant Staphylococcus aureus. The compound exhibited potent cytotoxic activity against breastcarcinoma (MCF-7), melanoma cells (A375), prostate carcinoma (DU145) and lung carcinoma (A549) cellswith IC values 20μg/ml. The symbiotic Streptomyces capillispiralis MTCC 10471 produces crude antibiotic30mg/Lt by using nonoptimized fermentation conditions. The structure of the antibiotic was explained by 1D,2D NMR and LC-ESI-MS/MS, MALDI-TOF/MS experiments, revealed that it belongs to cyclic ploy peptideActinomycin D

INTERACTING MULTIPLE MODEL SEEKER FILTER FOR TRACKING EVASIVE TARGETS

Seeker filter is an important subsystem in modern homing guidance system of advanced intercepting missiles. Seeker filter design for homing guidance requirements are highly demanding and challenging. Very low filter lag, high noise attenuation are some of the challenges that need to be addressed. This paper presents an interacting multiple model augmented extended Kalman filter (IMM-AEKF) design to operate as seeker filter in close loop homing guidance of an interceptor to track evasive targets. The performance of the seeker filter is verified with six degree of freedom interceptor-target engagement simulation with seeker filter in guidance loop of the interceptor. Different filter performance criteria have been used to verify the performance of the seeker filter. The seeker filter efficiently handles the various seeker noise and provides a smooth estimate of target states to generate guidance command for intercepting missile. The miss distance achieved is within the acceptable limits

Comprehensive Exordium of Monte Carlo Simulation Technique: An Alternative Approach for Measurement Uncertainty Evaluation

Precise and accurate measurements are essential for reliable experimental investigations and establishments of immaculate scientific theories. It has been realized that the measurement observations are always accompanied by certain reservations, hence to provide quality measurements, systematic assessment of these uncertainties is of much significance. This article attempts to demonstrate the procedure for measurement uncertainty evaluation using Law of Propagation of Uncertainties (LPU) and Monte Carlo Simulation (MCS) technique as per the recommendations of JCGM 101: 2008 using Microsoft Excel. Interestingly, it has been perceived that the expanded uncertainty values and histograms acquired using Law of Propagation of Uncertainties (LPU) and Monte Carlo Simulation (MCS) are distinctive
