EXTRACTION OF XYLAN DEGRADING ENZYME FROM SOIL ISOLATES FOR ITS APPLICATION AS BIOBLEACHING AGENT IN PAPER PULP PROCESSING
MOHAN GAANAPPRIYA,L. VIJAYKUMAR
Indian Streams Research Journal , 2013,
Abstract: The use of hemicellulolytic enzymes has recently attracted considerable interest as a substitute for chlorine chemicals in pulp bleaching in view of the environmental concerns. Fungal biotechnology opens a potpourri of strains for identification and secondary metabolite extractions. The present work aims in extraction of xylanase from novel microorganism(s) for its commercial application as biobleaching agent in paper and pulp industries. Eight xylanolytic fungi were isolated for the enzyme production. The culture conditions for enzyme production were optimized. The optimal enzyme activity was assayed for the xylanse enzyme. The results of the work were discussed with related references.

Abstract: Necrotizing fasciitis is an uncommon but a potentially fatal condition and can affect any part of the body. Most patients have pre-existing conditions that render them susceptible to infection, although etiology is unclear. Diagnosis is primarily clinical and is often delayed because of the unfamiliarity of the condition among clinicians. Management consists of immediate resuscitation, early surgical debridement, and administration of broad spectrum intravenous antibiotics. We report a case of a 70 year old woman who presented with a painful erythematous rash, was admitted as a case of cellulitis, later developed worsening of symptoms and septic shock, and was diagnosed as necrotizing fasciitis. 1. Introduction Necrotizing fasciitis is an uncommon disease that results in morbidity and mortality if not treated early. Most patients who develop necrotizing fasciitis have preexisting conditions that render them susceptible to infection. Advanced age, diabetes mellitus, chronic renal failure, peripheral vascular disease, and drug misuse seem to be risk factors [1]. We report a case of necrotizing fasciitis in a diabetic patient who presented with redness and pain of right thigh. 2. Case Report A 70-year-old woman with a history of noninsulin requiring diabetes mellitus, hypertension, hyperlipidemia, and chronic atrial fibrillation on warfarin therapy, returning home from a cruise to Bahamas, presented to the emergency room. She reported a one-day history of a 10/10 pain in right thigh and leg, subjective fever, and nausea. Physical examination revealed blood pressure 133/89?mm?Hg, heart rate 94/minute, respiratory rate 18/minute, and temperature 101.30?F. Oxygen saturation was 96% on room air. There was marked erythema with induration of the skin involving the posterior thigh and leg along with the popliteal fossa measuring about 12?cm in length. Laboratory and radiological investigation revealed a white blood cell count of 19.7/μL with 85% neutrophils, D-dimer of 2.9, and an international ratio (INR) of 3.16. Doppler ultrasound of the right lower extremity was negative for deep venous thrombosis. She was admitted with the diagnosis of cellulitis and started on intravenous clindamycin and fluids. On hospital day one, there was worsening of the lower extremity pain and erythema (Figures 1, 2, 3, and 4), with development of disseminated intravascular coagulation (DIC) and septic shock. Subsequent lab results showed sodium 144?mmol/L (millimoles/litre), potassium 4.2?mmol/L, chloride 97?mmol/L, and bicarbonate 12?mmol/L. Blood glucose was 181?mg/dL, and

Abstract: The analysis of rapid environment changes requires orbital sensors with high frequency of data acquisition to minimize cloud interference in the study of dynamic processes such as Amazon tropical deforestation. Moreover, a medium to high spatial resolution data is required due to the nature and complexity of variables involved in the?process. In this paper we describe a multiresolution multitemporal technique to simulate?Landsat 7 Enhanced Thematic Mapper Plus (ETM+) image using Terra Moderate?Resolution Imaging Spectroradiometer (MODIS). The proposed method preserves the?spectral resolution and increases the spatial resolution for mapping Amazon Rainfores?deforestation using low computational resources. To evaluate this technique, sample?images were acquired in the Amazon rainforest border (MODIS tile H12-V10 and?ETM+/Landsat 7 path 227 row 68) for 17 July 2002 and 05 October 2002. The MODIS-based simulated ETM+ and the corresponding original ETM+ images were compared through a linear regression method. Additionally, the bootstrap technique was used to calculate the confidence interval for the model to estimate and to perform a sensibility analysis. Moreover, a Linear Spectral Mixing Model, which is the technique used for deforestation mapping in Program for Deforestation Assessment in the Brazilian Legal Amazonia (PRODES) developed by National Institute for Space Research (INPE), was applied to analyze the differences in deforestation estimates. The results showed high correlations, with values between 0.70 and 0.94 (p < 0.05, student’s t test) for all ETM+ bands, indicating a good assessment between simulated and observed data (p < 0.05, Z-test). Moreover, simulated image showed a good agreement with a reference image, originating commission errors of 1% of total area estimated as deforestation in a sample area test. Furthermore, approximately 6% or 70 km2 of deforestation areas were missing in simulated image classification. Therefore, the use of Landsat simulated image provides better deforestation estimation than MODIS alone.

Brazilian Journal of Physics , 2003, DOI: 10.1590/S0103-97332003000300023
Abstract: this paper describes an innovative technique, the gradient pattern analysis (gpa), for analysing spatially extended dynamics. the measures obtained from gpa are based on the spatio-temporal correlations between large and small amplitude fluctuations of the structure represented as a dynamical gradient pattern. by means of four gradient moments it is possible to quantify the relative fluctuations and scaling coherence at a dynamical numerical lattice and this is a set of proper measures of the pattern complexity and equilibrium. the gpa technique is applied for the first time in 3d-simulated molecular chains with the objective of characterizing small symmetry breaking, amplitude and phase disorder due to spatio-temporal fluctuations driven by the spatially extended dynamics of a relaxation regime.

Abstract: The contemporary scientific literature that deals with the dynamics of marine chlorophyll-a concentration is already customarily employing data mining techniques in small geographic areas or regional samples. However, there is little focus on the issue of missing data related to chlorophyll-a concentration estimated by remote sensors. Intending to provide greater scope to the identification of the spatiotemporal distribution patterns of marine chlorophyll-a concentrations, and to improve the reliability of results, this study presents a data mining approach to cluster similar chlorophyll-a concentration behaviors while implementing an iterative spatiotemporal interpolation technique for missing data inference. Although some dynamic behaviors of said concentrations in specific areas are already known by specialists, systematic studies in large geographical areas are still scarce due to the computational complexity involved. For this reason, this study analyzed 18 years of NASA satellite observations in one portion of the Western Atlantic Ocean, totaling more than 60 million records. Additionally, performance tests were carried out in low-cost computer systems to check the accessibility of the proposal implemented for use in computational structures of different sizes. The approach was able to identify patterns with high spatial resolution, accuracy and reliability, rendered in low-cost computers even with large volumes of data, generating new and consistent patterns of spatiotemporal variability. Thus, it opens up new possibilities for data mining research on a global scale in this field of application.

Indian Journal of Community Medicine , 2010,
Abstract: Background: Infectious disease and malnutrition are common in children. Primary health care came into being to decrease the morbidity. Quality assessment is neither clinical research nor technology assessment. It is primarily an administrative device used to monitor performance to determine whether it continues to remain within acceptable bounds. Aims and Objectives: To assess the quality of service in the delivery of child health care in a primary health care setting. To evaluate client satisfaction. To assess utilization of facilities by the community. Materials and Methods: Study Type: Cross-sectional community-based study. Quality assessment was done by taking 30-50%, of the service provider. Client satisfaction was determined with 1 Immunization and child examination-90 clients each. Utilization of services was assessed among 478 households. Statistical Analysis: Proportions, Likert′s scale to grade the services and Chi-square. Results: Immunization service: Identification of needed vaccine, preparation and care was average. Vaccination technique, documentation, EPI education, maintenance of cold chain and supplies were excellent. Client satisfaction was good. Growth monitoring: It was excellent except for mother′s education andoutreach educational session . Acute respiratory tract infection care: History, physical examination, ARI education were poor. Classification, treatment and referral were excellent. Client satisfaction was good. Diarrheal disease care: History taking was excellent. But examination, classification, treatment, ORT education were poor. Conclusion: Mothers education was not stressed by service providers. Service providers′ knowledge do not go with the quality of service rendered. Physical examination of the child was not good. Except for immunization other services were average.
Client Satisfaction in Rural India for Primary Health Care – A Tool for Quality Assessment
Rashmi,Vijaykumar B
Al Ameen Journal of Medical Sciences , 2010,
Abstract: Introduction: The hospital market has today changed from a seller’s market to a buyers’ market, where the patient is all-important. One needs to understand the fact that patients do not flock to a hospital just because its services are cheap, but because of its good name and good image. Objective: To evaluate client satisfaction with the government approach in primary health care. Materials and Methods: Study design: Cross sectional study Sampling: Multistage sampling. Procedure: 1) The district was stratified into taluks 1 Primary Health Center and 1 Primary Health Unit or 1 Community Health Center (where there is a CHC) from each taluk was selected using random numbers. 2) Client satisfaction was determined by systematic random sampling of clients attending the basic health services Results: Client satisfaction in availability of service was above 90% in all services except in accident care where 30% were dissatisfied. Client satisfaction for facilities and equipments was good in all services except leprosy care and tuberculosis care where it was poor. Clients were mainly unhappy with the waiting time in all the services; in few services they expected speciality care like in child care and antenatal care. High risk care during delivery was not much appreciated. Other major problem was unavailability of the health care provider which led to dissatisfaction. Family planning services were graded excellent without any drawbacks. Except for few setbacks all the services had good satisfaction by majority of clients. Conclusion: Client satisfaction is good on a whole. Key words: Client satisfaction, primary health care, efficacy to treat, antenatal care, child care Key Message: The hospital market has today changed from a seller’s market to a buyers’ market, where the patient is all-important in that context we prioritize clients in primary health care too. Clients attending primary health care were mainly unhappy with the waiting time in all the services; in few services they expected speciality care as in child care and antenatal care. Other major problem was unavailability of the health care provider at night times which led to dissatisfaction. Family planning services were graded excellent by the clients.
