BACKGROUND Depression in old age is an important public health problem causing considerable morbidity and disability worldwide. There is a dearth of community studies from India investigating geriatric depression and its associated risk factors. This study aimed to establish the nature, prevalence and factors associated with geriatric depression in a rural(More)
OBJECTIVE This study attempted to evaluate sensitivity, specificity and predictive values of the diagnosis of dementia made by trained community health workers. METHOD A total of 1,000 subjects over the age of 65 years were recruited for the study. The community health workers identified nine subjects as having dementia. This was compared against an(More)
BACKGROUND Different interview schedules and diagnostic criteria for dementia have contributed to differing incidence and prevalence rates. AIM This study aimed to examine the effect of different diagnostic criteria on the prevalence of dementia in the community. METHODS Some 1000 subjects (>65 years) were recruited in Kaniyambadi Block, Vellore, India,(More)
BACKGROUND Many screening instruments for the diagnosis of dementia are not education and culture fair. In addition, despite good sensitivity and specificity, they result in unacceptable levels of false positives when used in the community. This study aimed to develop appropriate instruments for populations with low literacy and to consider strategies to(More)
Document classification can be defined as the task of automatically categorizing collections of electronic documents into their annotated classes, based on their contents. In recent years this has become important due to the advent of large amount of data in digital form. For several decades now document classification in the form of text classification(More)

Standardization of induction of oxidative stress with Fenton mixture (FM) in isolated perfused rat kidney and the antioxidant effect of Terminalia arjuna bark in the isolated oxidatively stressed rat kidney has been evaluated. Six groups each containing eight isolated perfused rat kidneys were used for the present study and the oxidative stress was induced(More)
An appropriate method for fault location on Extra High Voltage (EHV) transmission line using Support Vector Machine (SVM) is proposed in this paper. It relies on the application of SVM and frequency characteristics of the measured single end positive sequence voltage and current measurement of transient signals of the system. This paper is proposing a new(More)
