One pot synthesis of 2-hydroxy pyrrolidine derivatives
Putta. P. Varma,Kittappa. M. Mahadevan,Abdul Khader,Vijaykumar Hulikal
Organic Communications , 2011,
Abstract: One pot reaction of various 2-amino-thiadiazoles or thiazoles and 2,3- dihydrofuran under mild condition in presence of CeCl 3.7H 2O as catalyst transformed the amino group of 2-amino-thiadiazoles or thiazoles into a medicinally important 2-hydroxy pyrrolidine ring system in good to excellent yields. The generality of the reaction was sufficiently investigated and demonstrated. The new reaction path way for this conversion was established by spectroscopic and analytical methods.
Collective behavior of viscoelastic asperities as a model for static and kinetic friction
Srivatsan Hulikal,Kaushik Bhattacharya,Nadia Lapusta
Physics , 2014, DOI: 10.1016/j.jmps.2014.10.008
Abstract: We propose a statistical model for static and sliding friction between rough surfaces. Approximating the contact between rough surfaces by the contact of an ensemble of one-dimensional viscoelastic elements with a rough rigid surface, we study the collective behavior of the elements. We find that collective response of the contacts can lead to macroscopic behavior very different from the microscopic behavior. Specifically, various observed features of friction emerge as collective phenomena, without postulating them directly at the microscale. We discuss how parameters in our model can be related to material and surface properties of the contacting surfaces. We compare our results to commonly used rate and state phenomenological models, and propose a new interpretation of the state variable.

Quality assessment of child care services in primary health care settings of Central Karnataka (Davangere District)
Rashmi,Vijaykumar B
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.

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.
Reconstruction of chest, abdominal walls and perineum
Vijaykumar D,Vijayaraghavan Sundeep
Indian Journal of Plastic Surgery , 2007,
Abstract: The structural integrity of the chest and abdominal walls and perineum is frequently altered by cancer extirpation. Advances in reconstructive surgery and the availability of innovative techniques have helped the cancer surgeon to proceed with radical excisions with minimum morbidity. The ability to harvest flaps from distant sites and the availability of good prosthetic materials have now become part of the routine armamentarium of the plastic surgeon engaged in reconstructive surgery of these areas. Newer technologies incorporating tissue engineering may allow the reconstructive surgeon to achieve better functional and aesthetic rehabilitation of these patients.
Studies of fresh water foam fungi of Uttara Kannada, Karnataka
Indian Phytopathology , 2012,
Abstract: Foam formed in aquatic ecosystems acts as a trap for many fungal spores and in particular of aquatic Hyphomycetes. Therefore foam samples collected were scanned for a period of two years. This survey revealed the presence of 36 species of foam flora out of which 8 species are new to Karnataka and 9 species are new additions to the fungi of India. However spores of Beltrania, Curvularia and Tetraploa were also observed. All the fungi observed have been discussed in the paper.
Augmented Reality Repair Guidance System
Sidharth Bhatia,P. Vijaykumar
International Journal of Computer Science Issues , 2012,
Abstract: The daily life of a common man revolves around various forms of appliances/gadgets he uses throughout the day such as a mobile phone, laptop, printer, microwave oven, washing machine, etc. Although these appliances/gadgets are taken by most of the people for granted, the problem occurs when any of these things do not work as they are expected to. Getting them to the repair shops for every small glitch is expensive as well as time consuming. Although most of the companies which produce these appliances/gadgets do supply them with basic manuals, which deal with how to solve these minor issues, but reading them and at the same time repairing the corresponding appliance/gadget can be a frustrating task at times. These problems can be reduced to a large extent if some kind of live guidance is available. In this paper we propose a method to do so with the help of an augmented reality based system that will guide the user to carry out small scale repair jobs on these gadgets. All that is required is a decent webcam and a computing device, with a processor of 1 GHz or more and a display screen.
