    The Western Ghats of India is the one of the world's 10 "Hottest biodiversity hotspots" that runs along the western part of India through four states including Tamil Nadu. The only biodiversity reserve in the Western Ghats is the Nilgiri biosphere located in the Tamil Nadu state. In the present study, 525 soil samples were collected from all the 14 different divisions of the Western Ghats in Tamil Nadu state, India. A total of 316 new isolates of Bacillus thuringiensis (Bt) that produce parasporal crystalline inclusions were isolated from 525 soil samples. Seven different types of crystalline inclusions were observed in the 316 new isolates of Bt. Cuboidal inclusion was predominantly present in 26.9% of the Bt isolates when compared to other shapes. Further characterization of 70 of the 316 Bt isolates for crystal protein profile through SDS-PAGE revealed six different types of crystal protein profile viz., 135 and 65, 135, 95, 65, 43, and 30 kDa crystal proteins. Variation in the mass of crystal protein(s) purified from the isolates of Bt revealed molecular diversity of this bacterium prevalent in the Western Ghats of Tamil Nadu, India.

    Ambient particulate matter (PM) collected in the vicinity of five industries (Cement, Chemical, Thermal power plant, Sponge-iron and Steel) in Tamil Nadu state, India was characterized for size distribution, metals and polycyclic aromatic hydrocarbons (PAHs) content. Genotoxicity of PM and organic matter (OM) extracted from PM was measured in human lung cancer cell-line, A549 and in human liver carcinoma cell-line, HepG2, respectively, using the comet assay. PM values varied from 57.0 μg/m(3) of air at Cement industry upstream to 561.0 μg/m(3) of air at Sponge iron industry downstream samples. Their metal content varied from 5.758 μg/m(3) of air at Chemical industry to 46.144 μg/m(3) of air at Sponge iron industry and PAH concentration varied from 0.5 ng/m(3) air in upstream Thermal power plant to 3302.4 ng/m(3) air in downstream Sponge iron industry samples. While all PM samples induced DNA strand breaks at higher dose levels, downstream samples of Steel and Sponge iron industries which contained relatively higher concentrations of PAHs and metals and exhibited higher levels of pro-oxidant activity as measured by DTT activity induced significantly higher levels of DNA damage in HepG2 and A549 cells. Pretreatment of A549 cells with vitamin C or quercetin significantly reduced PM induced DNA strand breaks. Copyright © 2014 Elsevier B.V. All rights reserved.

    The Nilgiri hills provides favourable ecological conditions for the propagation of haematophagous arthropods due to its richness in vegetation and animal fauna. A study was undertaken by the NICD during August to November 1996 on the prevalence of ectoparasitic ticks from different localities of the Nilgiris district of Tamil Nadu state. The ticks were hand picked from various domestic animals of the study area and identified. A total of 1232 adults and immatures of ticks were collected from domestic animals which comprised of the various species in the order of abundance Boophilus microplus, Haemaphysalis bispinosa, Riphicephalus haemaphysaloides and Riphicephalus sanguineus. Studies carried out in the grass lands, meadows and areas adjoining to tea plantations by flagging method revealed mainly immature stages and few adults of Riphicephalus Spp. and Haemaphysalis Spp. The public health importance of the above species have been discussed.

    Full Text Available The objective of the paper is to examine price transmission process between wholesale and retail markets by adopting Asymmetric Price Transmission (APT Model.  The paper has taken a case of Onion ((Allium cepa L. wholesale and retail markets in Tamil Nadu state, India.   The paper used wholesale and retail prices data from secondary sources.  The results show that high margin at retail and wholesale levels of prices points to possibility of distortion in prices which may lead to an asymmetric process in the vertical market. The speed and magnitude of price changes and also the type of asymmetry in the vertical market system has identified the presence of both positive and negative asymmetry. With respect to speed, where the markets have shown negative asymmetry, there is evidence of retail prices responding much faster to decrease in wholesale prices than to increases in wholesale prices. Where a positive asymmetry holds, the result is the opposite. Keywords: Vegetables, Asymmetry, Efficiency, Market Integration and Symmetry

    Full Text Available India is experiencing energy crisis and a widening gap between energy supply and demand. The country is, however, endowed with considerable, commercially and technically available renewable resources, from which surplus agro-biomass is of great importance and a relatively untapped resource. In the policy making process, knowledge of existing biomass use, degree of social reliance, and degree of biomass availability for energy production is unequivocal and pre-conditional. Field observations, documentation, and fill-in sheet tools were used to investigate the potential of biomass resources and the existing domestic, commercial, and industrial uses of biomass in selected Indian states. To do so, a team of field observers/supervisors visited three Indian states namely: Maharashtra (MH, Madhya Pradesh (MP, and Tamil Nadu (TN. Two districts from each state were selected to collect data regarding the use of biomass and the extent of biomass availability for energy production. In total, 471 farmers were interviewed, and approximately 75 farmers with various land holdings have been interviewed in each district. The existing uses of biomass have been documented in this survey study and the results show that the majority of biomass is used as fodder for domestic livestock followed by in-site ploughing, leaving trivial surplus quantities for other productive uses. Biomass for cooking appeared to be insignificant due to the availability and access to Liquefied Petroleum Gas (LPG cylinders in the surveyed districts. Opportunities exist to utilize roadside-dumped biomass, in-site burnt biomass, and a share of biomass used for ploughing. The GIS-based maps show that biomass availability varies considerably across the Taluks of the surveyed districts, and is highly dependent on a number of enviromental and socio-cultural factors. Developing competitive bioenergy market and enhancing and promoting access to more LPG fuel connections seem an appropriate socio

    Full Text Available Abstract Local knowledge systems are not considered in the conservation of fragile seagrass marine ecosystems. In fact, little is known about the utility of seagrasses in local coastal communities. This is intriguing given that some local communities rely on seagrasses to sustain their livelihoods and have relocated their villages to areas with a rich diversity and abundance of seagrasses. The purpose of this study is to assist in conservation efforts regarding seagrasses through identifying Traditional Ecological Knowledge (TEK from local knowledge systems of seagrasses from 40 coastal communities along the eastern coast of India. We explore the assemblage of scientific and local traditional knowledge concerning the 1. classification of seagrasses (comparing scientific and traditional classification systems, 2. utility of seagrasses, 3. Traditional Ecological Knowledge (TEK of seagrasses, and 4. current conservation efforts for seagrass ecosystems. Our results indicate that local knowledge systems consist of a complex classification of seagrass diversity that considers the role of seagrasses in the marine ecosystem. This fine-scaled ethno-classification gives rise to five times the number of taxa (10 species = 50 local ethnotaxa, each with a unique role in the ecosystem and utility within coastal communities, including the use of seagrasses for medicine (e.g., treatment of heart conditions, seasickness, etc., food (nutritious seeds, fertilizer (nutrient rich biomass and livestock feed (goats and sheep.

    Full Text Available There is evidence that a specific type of allergic conjunctive-uveal granuloma reported from South India could be due to infection by a trematode parasite. In these patients, the histopathological examination of the eye reveals a zonal granulomatous inflammation with purulent material including structures displaying evidence of trematode infection. To investigate this further, medical records describing such cases in the Pudukkottai district, Tamil Nadu State, India, covering the period 2001-2005, were collected. Since trematodes require a snail intermediate host for completing the life cycle, ponds frequently used for bathing in the area were inspected to identify a possible culprit. The hypothesis that ponds with snail habitats could be the source of infection was supported by the finding of a positive correlation between the geographical distribution of patients’ residencies and the location of such ponds. Geographic information systems (GIS were used to study the spatial distribution of ponds and patients, while satellite-based remote sensing (RS was applied to attempt finding a parameter characteristic for ponds with snail habitats that could facilitate risk-identification over larger areas. It was found that ponds carrying risk could be differentiated from others through analysis of their spectral surface properties. This pond classification approach, confirmed by field visits, could thus become a useful tool for the location of snail habitats constituting risk as predicted.

    The latest report by the National Crime Records Bureau has positioned Tamil Nadu as the Indian state with highest suicide rate. At least in part, this is happening due to exam pressure among adolescents, emphasizing the imperative need to understand the pattern of anxiety and various factors contributing to it among students. The present study was conducted to analyze the level of state anxiety among board exam attending school students in Tamil Nadu, India. A group of 100 students containing 50 boys and 50 girls from 10th and 12th grades participated in the study and their state anxiety before board exams was measured by Westside Test Anxiety Scale. We found that all board exam going students had increased level of anxiety, which was particularly higher among boys and 12th standard board exam going students. Analysis of various demographic variables showed that students from nuclear families presented higher anxiety levels compared to their desired competitive group. Overall, our results showing the prevalence of state anxiety among board exam going students in Tamil Nadu, India, support the recent attempt taken by Tamil Nadu government to improve student's academic performance in a healthier manner by appointing psychologists in all government schools.

    The grey slender loris Loris lydekkerianus, one of only two nocturnal primates of India, is found in the southern part of the country. Our understanding of its geographical distribution is largely based on historical records and short surveys, and little is known of its occurrence in southern India today. We sought to establish the relative abundance of this species in 26 districts in the state of Tamil Nadu and the union territory of Pondicherry in southern India. We sighted lorises in 19 districts, and their relative abundance ranged from 0.01 to 2.21/km. The south-central districts of Tamil Nadu showed the highest densities of lorises, while the western districts showed the lowest. Based on these results, we recommend increased protection measures for the forest patches of the Eastern Ghats mountains in order to ensure the long-term survival of the grey slender loris.

    The Indian Ocean tsunami (IOT) devastated several countries of North Indian Ocean. India is one of the worst affected countries after Indonesia and Sri Lanka. In India, Tamil Nadu suffered maximum with fatalities exceeding 8,000 people. Historical records show that tsunami has invaded the shores of Tamil Nadu in the past and has made people realize that the tsunami threat looms over Tamil Nadu and it is necessary to evolve strategies for tsunami threat management. The IOT has brought to light that tsunami inundation and runup varied within short distances and for the disaster management for tsunami, large scale maps showing areas that are likely to be affected by future tsunami are identified. Therefore threat assessment for six villages including Mamallapuram (also called Mahabalipuram) which is famous for its rock-cut temples, from the northern part of Tamil Nadu state of India has been carried out and threat maps categorizing the coast into areas of different degree of threat are prepared. The threat was assessed by numerical modeling using TUNAMI N2 code considering different tsunamigenic sources along the Andaman - Sumatra trench. While GEBCO and C-Map data was used for bathymetry and for land elevation data was generated by RTK - GPS survey for a distance of 1 km from shore and SRTM for the inland areas. The model results show that in addition to the Sumatra source which generated the IOT in 2004, earthquakes originating in Car Nicobar and North Andaman can inflict more damage. The North Andaman source can generate a massive tsunami and an earthquake of magnitude more than Mw 9 can not only affect Tamil Nadu but also entire south east coast of India. The runup water level is used to demarcate the tsunami threat zones in the villages using GIS.

    Molecular characterization of measles viruses is a valuable tool for measuring the effectiveness of measles control and elimination programmes. WHO recommends that virological surveillance be conducted during all phases of measles control to document circulation of indigenous strains and trace future importation. This report describes the genetic characterization of wild type measles viruses from Tamil Nadu, India isolated between January 2005 and January 2006. In the study, 304 suspected measles cases (292 from 56 outbreaks and 12 sporadic cases) were investigated. Blood samples were collected from suspected measles outbreaks and 11 suspected sporadic cases and tested for the presence of measles and rubella specific IgM. Based on serological results, 53 outbreaks were confirmed as measles, 2 as a combination of measles and rubella, and 1 negative for both. Eight sporadic cases were confirmed as measles and one as rubella. Throat swab and urine samples were collected for virus isolation and 28 isolates were obtained. Sequencing and analysis showed that 3 isolates belonged to genotype D4 and 25 to genotype D8. Comparison of the genotype D8 sequences from Tamil Nadu with previously reported genotype D8 sequences from India and abroad showed six distinct clusters with Tamil Nadu strains forming two clusters. This study has established baseline molecular data and is the first report that describes genetic diversity of circulating measles strains in Tamil Nadu, a state in India. D8 has multiple lineages and this has been linked with importation of measles into the USA and UK.

    Full Text Available Background: Sexually transmitted infections (STIs are now recognized as a serious global threat to the health of population. Objectives: To assess the prevalence of sexually transmitted infections among young married scheduled castes women in Thiruvarur district of Tamilnadu state in India. Methods: A community based cross-sectional study was conducted in 28 villages selected using multistage sampling technique for selecting 605 women in the age group of 15-24 years during July 2010-April 2011. Data analysis was by use of SPSS version-17, with statistical significance set at p-value of 0.05. Results: Around 8.8% of women experienced sexually transmitted infections among the study population. The proportion of women who experienced STIs was seven times higher among illiterates (46.9% than women who completed secondary education (6%. The women in households in the high standard of living index (SLI were less likely to experience STIs (1.7% than women in low SLI (15.6%. The agricultural laborers were 1.145 times more likely to experience STIs than non-agricultural workers (OR=0.251. Conclusions: The main causes for sexual health problems were found to be the less education and lowest SLI among women. It is recommended that policy makers should be introduce community intervention programs to increase the awareness regarding sexual health issues among rural population.

    The resurgence of malaria in India began in 1966 and the states of Karnataka and Tamil Nadu were no exception to this phenomenon. In both states the peak occurrence came in 1976. Malaria was largely confined to highly vulnerable and receptive areas. The problem of increased incidence was particularly associated with the development of several irrigation and hydro-electric schemes. Improperly maintained irrigation systems and reservoirs provided ideal breeding grounds. The present paper examines the scope and limitations of a major anti-malaria activity, namely residual insecticide spraying as adopted and practised in rural vector control programmes in irrigation development project areas. Past experiences (as during the National Malaria Eradication programme, 1958-1965) and current practices are reviewed on the basis of selected examples. Eradication programme, 1958-1965) and current practices are reviewed on the basis of selected examples. In view of the current re-emergence of the disease, the states are faced with new obstacles to residual insecticide spraying such as (a) the development of resistance of malaria vectors to DDT and other alternative compounds like BHC (benzene hexachloride), changing vector behaviour with avoidance of contact with indoor insecticide deposits on walls, (c) environmental contamination (risks of chemicals), (d) extensive use of insecticides and pesticides for crop protection under an expanding green revolution agricultural technology, particularly in irrigated areas and (e) the existence of outdoor resting populations of the major vector Anopheles culicifacies and their role in extra-domiciliary transmission, making residual insecticide spray less effective. Spraying operations are also hindered by the persistence of certain social and cultural factors. The custom of mud plastering, white-washing and rethatching rural houses, for example, results in the loss of insecticide-treated surfaces. Other outdoor rural activities persist as

    Mangrove and halophytic plants occur along the coastal areas of Tamil Nadu, south India and these plants have been used in traditional medicine for centuries. Heavy metals are known to pose a potential threat to terrestrial and aquatic biota. However, little is known on the toxic levels of heavy metals found in mangrove and halophytic plants that are used in traditional medicine in India. To understand heavy metal toxicity, we investigated the bioconcentration factors (BCF) of heavy metals in leaves collected from eight mangroves and five halophytes in the protected Pichavaram mangrove forest reserve in Tamil Nadu State, south India. Data presented in this paper describe the impact of essential (Cu, Fe, Mg, Mn and Zn) and non-essential/environmentally toxic trace metals (Hg, Pb and Sn) in mangrove and halophytic medicinal plants. The concentrations of Pb among 13 plant species were higher than the normal range of contamination reported for plants. The average concentration of Hg in the halophytic plants (0.43 {+-} 0.37 {mu}g/g) was seven times higher than mangrove plants (0.06 {+-} 0.03 {mu}g/g) and it indicated pollutants from industrial sources affecting halophytes more than mangroves. - Metal effects occur in India's mangrove ecosystem.

    Objective:To isolate novel actinomycetes and to evaluate their antibacterial activity. Methods:Three soil samples were collected from Vengodu (village) in Kanchipuram district, Tamil Nadu, India. Actinomycetes were isolated using serial dilution and plating method on actinomycetes isolation agar. Results: Totally 35 isolates were obtained on the basis of colony characteristics on actinomycetes isolation agar. All the isolates were screened for antibacterial activity by cross streak method. Medium and optimization of day were done for the potent strains using Nathan's agar well diffusion method. Isolation of bioactive compounds from significant active isolates was done by using different media. The most active isolate VAS 10 was identified as Actinobacterium Loyola PBT VAS 10 (accession No. JF501398) using 16s rRNA sequence method. The hexane, ethyl acetate, dichloromethane and butanol extracts of VAS 10 were tested against bacteria. The maximum antibacterial activity was observed in dichloromethane and ethyl acetate;maximum zones of inhibition were observed against Enterococcus durans. The rRNA secondary structure and the restriction sites of Actinobacterium Loyola VAS 10 were predicted using Genebee and NEBCutter online tools respectively. Conclusions: The present study showed that among the isolated actinomycetes, Actinobacterium Loyola PBT VAS 10 (accession No. JF501398) showed good antibacterial activity against the tested bacteria.

    Full Text Available Hyperglycaemia in pregnancy (HIP, i.e. gestational diabetes mellitus (GDM and diabetes in pregnancy (DIP, increases the risk of various short- and long-term adverse outcomes. However, much remains to be understood about the role of different risk factors in development of HIP.The aims of this observational study were to examine the role of potential risk factors for HIP, and to investigate whether any single or accumulated risk factor(s could be used to predict HIP among women attending GDM screening at three centres in urban, semi-urban and rural Tamil Nadu, India.Pregnant women underwent a 75 g oral glucose tolerance test. Data on potential risk factors was collected and analysed using logistical regression analysis. Receiver operating characteristic (ROC curves, sensitivity, specificity and predictive values were calculated for significant risk factors and a risk factor scoring variable was constructed.HIP was prevalent in 18.9% of the study population (16.3% GDM; 2.6% DIP. Increasing age and BMI as well as having a mother only or both parents with diabetes were significant independent risk factors for HIP. Among women attending the rural health centre a doubling of income corresponded to an 80% increased risk of HIP (OR 1.80, 95%CI 1.10-2.93; p = 0.019, whereas it was not significantly associated with HIP among women attending the other health centres. The performance of the individual risk factors and the constructed scoring variable differed substantially between the three health centres, but none of them were good enough to discriminate between those with and without HIP.The findings highlight the importance of socio-economic circumstances and intergenerational risk transmission in the occurrence of HIP as well as the need for universal screening.

    The primary deciduous forests in the Eastern Ghats (EG) of Tamil Nadu (TN) India have undergone many changes owing to various need-based forest managements, such as timber extraction for industry, railway sleepers, charcoal, and forest clearance for hydroelectric projects and agriculture, during preindependence and postindependence periods (i.e., from 1800 to 1980). The enactment of a forest conservation act during the 1980s changed the perception of forest managers from utilization to conservation. This study was taken up to assess the forests dynamics in the EG of TN spatially between 1990 and 2003 and nonspatially between 1900 and the 1980s. Landsat Thematic Mapper (TM) and Indian Remote Sensing satellite (IRS) 1D Linear Imaging and Self Scanning (LISS III) data were used to assess forests during 1990 and 2003, respectively. Field floristic survey and secondary data (such as published literature, floras, books, and forest working plans) were used to assess the forest dynamics in terms of forest type and species composition among the preindependence period, the postindependence period, and the present (i.e., before and after 1980). The satellite data analysis revealed a considerable amount of changes in all forest types during the 13 years. The comparison of species composition and forest types between the past and present revealed that need-based forest management along with anthropogenic activity have altered the primary deciduous forest in to secondary and postextraction secondary forests such as southern thorn and southern thorn scrub forests in the middle [400-900 m above mean sea level (MSL)] and lower slopes (900 m MSL) and plateau seemed not to be much affected by the forest management. The changes estimated by the satellite data processing in the major forest types such as evergreen, deciduous, southern thorn, and southern thorn scrub are really alarming because these changes have occurred after the implementation of a forest conservation act.

    Full Text Available Background: Tamil Nadu is one of the 18 states affected by fluorosis in India. The maximum tolerance limit of fluoride in drinking water specified by the World Health Organization (WHO, 1984 is 1.5 mg/l while it is proved to be above in many areas of Salem. Aims and Objectives: The aim of the following study is to identify the prevalence of dental fluorosis among children in the district of Salem. To compare the prevalence of dental fluorosis between different sexes and age groups. Materials and Methods: A pilot study was conducted in a private school where oral examination was done using mouth mirror and probe under sunlight in 965 students, for the presence or absence of dental fluorosis. As it was a pilot study, the fluorosis indexes were not taken into consideration. Results: In our study, 965 students were examined for dental fluorosis out of which, 624 were boys and 341 were girls. Dental fluorosis was present in 31.1% of boys, and 30.3% of girls 297 students out of 965 (30.8% showed the presence of dental fluorosis. Conclusion: The present study showed that Salem is one of the districts affected by dental fluorosis in Tamil Nadu. An extensive study including the grades of fluorosis and estimation of water fluoride levels in different areas is required for better evaluation of the situation. Government should take actions to prevent fluorosis. Awareness should be given to the population to drink only the water supplied by the government.

    Salem is one of the industrial, agricultural and mineral deposit based district in Tamil Nadu. In this paper, an attempt is made to assess the quality of groundwater in this district, during the month of May 2007 (pre-monsoon). The government of Tamil Nadu has divided the district into twenty blocks. Sixty six samples were collected covering all the blocks of the district except Yercaud which is a structural hill. The collected samples were tested for the following parameters: electrical conductivity, turbidity, pH, total hardness, iron, chlorides, total dissolved solids, calcium, magnesium, potassium, manganese, sulphate, nitrate, nitrite and total alkalinity. The test results were interpreted using IS 10500-1991, statistical methods, SAR, USSL classification and Piper's trilinear diagram. Based on the interpretation it is concluded that the study area is mostly influenced by the presence of electrical conductivity, total dissolved solids, total hardness, chloride and total alkalinity whereas the other minerals and salts play a minor role.

    Tamil Nadu is located in the South-Eastern part of Indian peninsula, between 8.087° and 13.09°N and 76.50° and 80.27°E. Bluetongue (BT) was first reported in this region in sheep during 1982 with regular occurrence thereafter. In 1989-1990, 1997-1998 and 2005-2006, there was wide spread occurrence of BT resulting in huge mortality of sheep. The present study had the goal of isolating the BTV from outbreaks in sheep occurred in Tamil Naadu between 2003-2011 and comparing the VP2 gene sequences of the BTV isolates involved in such outbreaks. Serotypes 1, 2, 16, and 23 of the Bluetongue virus (BTV) have been isolated from sheep during BT outbreaks. BTV-16 has also been isolated in goats and cattle in the region; BTV-2 isolated in Tamil Nadu has homology with BTV-2 isolated in Africa; whereas the BTV-23 isolated in this area has homology with BTV-23 from South East Asia, indicating that both Eastern and Western topotypes of BTV are circulating in ruminant population in Tamil Nadu.

    This study has been undertaken to examine the occurrence of climate change in Tamil Nadu, the southernmost state of India and its impact on rainfall pattern which is a primary constraint for agricultural production. Among the five sample stations examined across the state, the minimum temperature has increased significantly in Coimbatore while the same has decreased significantly in Vellore whereas both minimum and maximum temperatures have increased significantly in Madurai since 1969 with climate change occurring between late 1980s and early 1990s. As a result, the south-west monsoon has been disturbed with August rainfall increasing with more dispersion while September rainfall decreasing with less dispersion. Thus, September, the peak rainfall month of south-west monsoon before climate change, has become the monsoon receding month after climate change. Though there has been no change in the trend of the north-east monsoon, the quantity of October and November rainfall has considerably increased with increased dispersion after climate change. On the whole, south-west monsoon has decreased with decreased dispersion while north-east monsoon has increased with increased dispersion. Consequently, the season window for south-west monsoon crops has shortened while the north-east monsoon crops are left to fend against flood risk during their initial stages. Further, the incoherence in warming, climate change and rainfall impact seen across the state necessitates devising different indigenous and institutional adaptation strategies for different regions to overcome the adverse impacts of climate change on agriculture.

    The Oddanchatram anorthosite is located in the Madurai District of Tamil Nadu, near the town of Palni. It is emplaced into a granulite facies terrain commonly presumed to have undergone its last regional metamorphism in the late Archean about 2600 m.y. The surrounding country rock consists of basic granulites, charnockites and metasedimentary rocks including quartzites, pelites and calc-silicates. The anorthosite is clearly intrusive into the country rock and contains many large inclusions of previously deformed basic granulite and quartzite within 100 meters of its contact. Both this intrusion and the nearby Kaduvar anorthosite show evidence of having been affected by later metamorphism and deformation.

    In situ radiometric survey carried out in 81 revenue villages of Kanyakumari District, Tamil Nadu, India, using a portable radiation dosemeter/detector, revealed the existence of radiation hotspots along the coastal belt. A close observation of the coastal villages specifically revealed high background radioactivity in 14 coastal villages. A very high intrinsic anomalous radioactivity of 41.03 μSv h(-1) was observed, in a famous tourist spot in the coastal belt of Kanyakumari District. This is the highest level of radiation registered in South India, which is extremely higher than the permissible world average and is suggestive of causing severe clinical problems on continuous and prolonged exposure.

    Faulty pricing policies and inadequate investment in the power sector are responsible for the chronic power shortages that plague Tamil Nadu and the rest of India. Formulae for optimal pricing rules are derived for a social welfare maximizing Electricity Board which sells electricity that is used both as an intermediate, and as a final good. Because of distributional constraints, the optimal prices deviate systematically from marginal costs. Optimal relative price-marginal cost differentials are computed for Tamil Nadu, and are found to indicate a lower degree of subsidization than the prevailing prices. The rationalization of electricity tariffs would very likely increase the Board's revenues. The cost-effectiveness of nuclear power in India is examined by comparing actual data for the Madras Atomic Power Project and the Singrauli coal-fired thermal power station. The conventional (non-environmental) costs of power generation are compared at both market prices and shadow prices, calculated according to the UNIDO guidelines for project evaluation. Despite favorable assumptions for the costs of the nuclear plant, coal had a decided edge over nuclear in Tamil Nadu. Remarkably, the edge varied little when market prices are replaced by shadow prices in the computations. With regard to the environmental costs, far too much remains unknown. More research is therefore needed on the environmental impacts of both types of power generation before a final choice can be made.

    Water quality of Tiruvallur Taluk of Tiruvallur district, Tamil Nadu, India has been analysed to assess its suitability in relation to domestic and agricultural uses. Thirty water samples, including 8 surface water (S), 22 groundwater samples [15 shallow ground waters (SW) and 7 deep ground waters (DW)], were collected to assess the various physico-chemical parameters such as Temperature, pH, Electrical conductivity (EC), Total dissolved solids (TDS), cations (Ca, Mg, Na, K), anions (CO3, HCO3, Cl, SO4, NO3, PO4) and trace elements (Fe, Mn, Zn). Various irrigation water quality diagrams and parameters such as United states salinity laboratory (USSL), Wilcox, sodium absorption ratio (SAR), sodium percentage (Na %), Residual sodium carbonate (RSC), Residual Sodium Bicarbonate (RSBC) and Kelley's ratio revealed that most of the water samples are suitable for irrigation. Langelier Saturation Index (LSI) values suggest that the water is slightly corrosive and non-scale forming in nature. Gibbs plot suggests that the study area is dominated by evaporation and rock-water dominance process. Piper plot indicates the chemical composition of water, chiefly controlled by dissolution and mixing of irrigation return flow.

    2011-01-01

    Objective:To assess the antifungal activity of hexane, ethyl acetate and methanol extracts of 45 medicinal plants and to determine the minimum inhibitory concentration for each extract against human pathogenic fungi. Methods:A total of 45 medicinal plants were collected from different places of Tamil Nadu and identified. Hexane, ethyl acetate and methanol extracts of 45 medicinal plants were assessed for antifungal susceptibility using broth microdilution method. Two known antifungal agents were used as positive controls. Results: Most of the extracts inhibited more than four fungal strains. From the evaluation we found that ethyl acetate extracts inhibited large number of fungal growth. Hexane extracts also nearly showed the same level of inhibition against fungal growth. Methanol extracts showed the minimum antifungal activity. Among the 45 plants tested, broad spectrum antifungal activity was detected in Albizzia procera (A. procera), Atalantia monophylla, Asclepias curassavica, Azima tetracantha, Cassia fistula (C. fistula), Cinnomomum verum, Costus speciosus (C. speciosus), Nymphaea stellata, Osbeckia chinensis, Piper argyrophyllum, Punica granatum, Tinospora cordifolia and Toddalia asiatica (T. asiatica). Promising antifungal activity was seen in A. procera, C. speciosus, C. fistula and T. asiatica. Conclusions:It can be concluded that the plant species assayed possess antifungal properties. Further phytochemical research is needed to identify the active principles responsible for the antifungal effects of some of these medicinal plants.

    The aim of the present study is to assess the prevalence of intestinal and haemoprotozoan parasites of small ruminants (Sheep and Goats) in North Western part of Tamil Nadu, India. A total of 630 faecal samples (251-sheep, 379-goats) and 554 blood smears (242-sheep, 312-goats) were examined, for the presence of eggs of intestinal and haemoprotozoan parasites, respectively. The samples were received from the Veterinary college hospital and Veterinary dispensaries in North Western part of Tamil Nadu. Faecal samples were processed by sedimentation technique and examined under low power objective (×10), and blood smears were stained using Giemsa's technique and examined under oil immersion (×100). The analysis of data on the prevalence of intestinal and haemoprotozoan parasites of sheep and goats in North Western part of Tamil Nadu for the period from 2004 to 2013, showed an overall prevalence of intestinal parasites was found to be 67% and 35% in sheep and goats, respectively, whereas only 11% of sheep and 3% of goats had the haemoprotozoan parasitic infection. Highly, significant difference (pparasitism was observed between sheep and goats. Intestinal parasites such as strongyles, Trichuris, Moniezia, amphistome, and coccidia were identified in which the highest prevalence was observed with coccidia, followed by strongyles, Monezia, Trichuris, and least with amphistome in both the sheep and goats. The haemoprotozoan parasites recorded were Theileria and Anaplasma species, of which, Anaplasma spp. being the highest and Theileria spp. the least prevalent in both the sheep and goats. The seasonal prevalence of intestinal parasites showed highest in rainy season, followed by moderate in winter and least with summer in both the sheep and goats, whereas the haemoprotozoan parasites recorded were the highest in summer followed by winter and least with rainy season. The present study suggests that North Western part of Tamil Nadu is highly endemic for intestinal parasites

    The study aimed to determine costs to the state government of implementing different interventions for controlling rabies among the entire human and animal populations of Tamil Nadu. This built upon an earlier assessment of Tamil Nadu's efforts to control rabies. Anti-rabies vaccines were made available at all health facilities. Costs were estimated for five different combinations of animal and human interventions using an activity-based costing approach from the provider perspective. Disease and population data were sourced from the state surveillance data, human census and livestock census. Program costs were extrapolated from official documents. All capital costs were depreciated to estimate annualized costs. All costs were inflated to 2012 Rupees. Sensitivity analysis was conducted across all major cost centres to assess their relative impact on program costs. It was found that the annual costs of providing Anti-rabies vaccine alone and in combination with Immunoglobulins was $0.7 million (Rs 36 million) and $2.2 million (Rs 119 million), respectively. For animal sector interventions, the annualised costs of rolling out surgical sterilisation-immunization, injectable immunization and oral immunizations were estimated to be $ 44 million (Rs 2,350 million), $23 million (Rs 1,230 million) and $ 11 million (Rs 590 million), respectively. Dog bite incidence, health systems coverage and cost of rabies biologicals were found to be important drivers of costs for human interventions. For the animal sector interventions, the size of dog catching team, dog population and vaccine costs were found to be driving the costs. Rabies control in Tamil Nadu seems a costly proposition the way it is currently structured. Policy makers in Tamil Nadu and other similar settings should consider the long-term financial sustainability before embarking upon a state or nation-wide rabies control programme.

    Full Text Available The study aimed to determine costs to the state government of implementing different interventions for controlling rabies among the entire human and animal populations of Tamil Nadu. This built upon an earlier assessment of Tamil Nadu's efforts to control rabies. Anti-rabies vaccines were made available at all health facilities. Costs were estimated for five different combinations of animal and human interventions using an activity-based costing approach from the provider perspective. Disease and population data were sourced from the state surveillance data, human census and livestock census. Program costs were extrapolated from official documents. All capital costs were depreciated to estimate annualized costs. All costs were inflated to 2012 Rupees. Sensitivity analysis was conducted across all major cost centres to assess their relative impact on program costs. It was found that the annual costs of providing Anti-rabies vaccine alone and in combination with Immunoglobulins was $0.7 million (Rs 36 million and $2.2 million (Rs 119 million, respectively.

    Full Text Available Until the 1990s the major edible oil consumed in Tamil Nadu state was peanut and sesame oil. The technological, economic and policy changes thereafter induced dynamism in consumer demand for food, including edible oils. In this study, the household demand for individual edible oils based on present consumption was assessed and forecasted for 2015 and 2020 for Tamil Nadu. Due to constraints in the secondary data published by National Sample Survey Organisation (NSSO, the primary data was used. The Almost Ideal Demand System (AIDS model was employed to estimate the income (expenditure elasticities and in turn used to project the demand for edible oils and associated products like ghee and butter. The overall edible oil demand is expected to grow at 7.0% per annum in Tamil Nadu, with the highest growth of sunflower oil (8.7% followed by other oils (7.8%, sesame oil (6.6%, peanut oil (6.6% and palm oil (3.1%. The demand for total edible oil in rural Tamil Nadu increases from 3.14 lakh tonnes (2009-10 to 5.3 lakh tonnes (2020, whereas, in urban areas, it increases from 3.24 lakh tonnes to 5.45 lakh tonnes. The non-traditional oil like sunflower oil and other oils (soybean, corn, rice bran, palm oil has made inroads in the consumption basket and will continue to dominate in the future. Hence, concerted efforts like increasing seed replacement rate, increasing the intensity of adoption of improved technology and appropriate price policy are required to increase productivity of non-traditional crops besides promoting traditional crops (peanut and sesame to meet the growing edible oil demand in the state.

    South India is characterized by a wide variety of landscapes, soils and climatic zones. It is comprised of tropical, semi-arid, humid-moist, and high-altitude environments, which support a diversity of agricultural systems. Our study focused on the state of Tamil Nadu, which is characterized by a generally tropical climate, and receive rainfall during both the southwest monsoon season (SWM, June to September) and the northeast monsoon (NEM, September to December). Agriculture continues to be an important sector in the state economy, as more than 56 of the people depend on agriculture and allied sectors for their livelihood. Analysis of land-use patterns in Tamil Nadu reveals that in the past decade there has been a reduction in net sown area and current fallow, while the share of cultivable wastelands has increased. The area under cereals, pulses, and oilseeds had marginally declined, although area under commercial crops like turmeric, sugar-cane, banana, fruits, and vegetables has shown an increasing trend. The production performance of major crops like cereals, pulses, and oilseeds has not shown any significant increase. Demand and supply gap of important crops in Tamil Nadu for the year 2010 indicates that the state is lagging far behind in the production of various crops.

    South coast of India is known as the high-level background radiation area (HBRA) mainly due to beach sands that contain natural radionuclides as components of the mineral monazite. The rich deposit of monazite is unevenly distributed along the coastal belt of Tamil Nadu and Kerala. An HBRA site that laid in 2×7 m along the sea was found in the beach of Chinnavillai, Tamil Nadu, where the maximum ambient dose equivalent reached as high as 162.7 mSv y(-1). From the sands collected at the HBRA spot, the high-purity germanium semi-conductor detector identified six nuclides of thorium series, four nuclides of uranium series and two nuclides belonging to actinium series. The highest radioactivity observed was 43.7 Bq g(-1) of Th-228. The individual dose of five inhabitants in Chinnavillai, as measured by the radiophotoluminescence glass dosimetry system, demonstrated the average dose of 7.17 mSv y(-1) ranging from 2.79 to 14.17 mSv y(-1).

    Courtallam Falls of the river Chittar in Tamil Nadu (India) is a place of tourist attraction during the southwest monsoon season. Particularly, in this season high input of detergents and other anthropogenic activities tend to bring in undesirable materials into the water body, whereby the pristine quality is altered. Therefore, a study was undertaken in the peak southwest tourist season to assess physico-chemical and biological quality of the river Chittar. After carrying out analytical study of various water samples, it was found that although the river was not found highly polluted, biological quality was found significantly poor. Excluding sulphate, all the other physico-chemical parameters analyzed were found within the permissible limits. However, the total and faecal coliforms exceeded the permissible limits, indicating a poor status of the river.

    This study reports physicochemical characteristics and their sources in groundwater in Thirupathur region in Tamil Nadu, India. For this purpose, groundwater samples were collected and analysed using standard methods. A wide seasonal variation was showed for the majority of the samples; higher concentration was observed in the pre-monsoon season. Concentration of fluoride was quite alarming in many locations. Groundwater is found to be dominated by Na+, Ca+, HCO3 and Cl-. Gibbs plot showed the dominance of rock-water interaction. Geology of the area in comparison with the results obtained in the chemical cross plots showed the dominance of silicate weathering, with a minor contribution from the cation exchange. Other processes such as evaporation dissolution of carbonate and gypsum were proved to be ineffective. However, dissolution of fluoride minerals present in the geological formation is the major source of fluoride in groundwater.

    In this paper, we present regional climate change projections for the Tamil Nadu state of India, simulated by the Met Office Hadley Centre regional climate model. The model is run at 25 km horizontal resolution driven by lateral boundary conditions generated by a perturbed physical ensemble of 17 simulations produced by a version of Hadley Centre coupled climate model, known as HadCM3Q under A1B scenario. The large scale features of these 17 simulations were evaluated for the target region to choose lateral boundary conditions from six members that represent a range of climate variations over the study region. The regional climate, known as PRECIS, was then run 130 years from 1970. The analyses primarily focus on maximum and minimum temperatures and rainfall over the region. For the Tamil Nadu as a whole, the projections of maximum temperature show an increase of 1.0, 2.2 and 3.1 °C for the periods 2020s (2005-2035), 2050s (2035-2065) and 2080s (2065-2095), respectively, with respect to baseline period (1970-2000). Similarly, the projections of minimum temperature show an increase of 1.1, 2.4 and 3.5 °C, respectively. This increasing trend is statistically significant (Mann-Kendall trend test). The annual rainfall projections for the same periods indicate a general decrease in rainfall of about 2-7, 1-4 and 4-9 %, respectively. However, significant exceptions are noticed over some pockets of western hilly areas and high rainfall areas where increases in rainfall are seen. There are also indications of increasing heavy rainfall events during the northeast monsoon season and a slight decrease during the southwest monsoon season. Such an approach of using climate models may maximize the utility of high-resolution climate change information for impact-adaptation-vulnerability assessments.

    Full Text Available Landslide includes a wide range of ground movements, such as rock falls, deep failure of slope, and shallow debris flows. Although gravity acting on an over steepened slope is the primary reason for a landslide. The Nilgiri Hills (Mountains of Tamil Nadu, India are prone to landslides, which often result in considerable damage to private property, public infrastructure, and loss of life. The mapping of LVZ includes, the preparation of various thematic layers from different data sources, such as Survey of India topographic sheets, Satellite data, Geological Survey of India maps etc. These landslides are typically the result of the structural failure of thick laterite soils that have been saturated by heavy rains during the monsoon season. . GIS have proved to be useful tools for analyzing and managing landslide related data. GIS has been widely used in quantitative estimation landslide susceptibility. The methodology adopted for the identification of landslide vulnerable zones, and suggestion of remedial measures based on the vulnerability of landslides on different terrain parameters per unit area. Through this study, it is evinced again that the geomatics technology is a proven tool for landslide studies in order to properly understand, identify and suggest remedial measures.

    In Tamil Nadu, India, improvements have been made toward developing a high-quality, universally accessible healthcare system. However, some rural residents continue to confront significant barriers to obtaining healthcare. The primary objective of this study was to investigate self-reported morbidity, health literacy, and healthcare preferences, utilization, and experiences in order to identify priority areas for government health policies and programs. Drawing on 66 semi-structured interviews and 300 household surveys (including 1693 individuals), administered in 26 rural villages in Tamil Nadu's Krishnagiri district, we found that the prevalence of self-reported major health conditions was 22.3%. There was a large burden of non-communicable and chronic diseases, and the most common major morbidities were: connective tissue problems (7.6%), nervous system and sense organ diseases (5.0%), and circulatory and respiratory diseases (2.5%). Increased age and decreased education level were associated with higher odds of reporting most diseases. Low health literacy levels resulted in individuals seeking care only once pain interfered with daily activities. As such, individuals' health-seeking behaviour depended on which strategy was believed to result in the fastest return to work using the fewest resources. Although government facilities were the most common healthcare access point, they were mistrusted; 48.8% and 19.2% of respondents perceived inappropriate treatment protocols and corruption, respectively, at public facilities. Conversely, 93.3% of respondents reported high treatment cost as the main barrier to accessing private facilities. Our results highlight that addressing the chronic and non-communicable disease burdens amongst rural populations in this context will require health policies and village-level programs that address the low health literacy and the issues of rural healthcare accessibility and acceptability.

    Full Text Available BACKGROUND: Snakebite represents a significant health issue worldwide, affecting several million people each year with as many as 95,000 deaths. India is considered to be the country most affected, but much remains unknown about snakebite incidence in this country, its socio-economic impact and how snakebite management could be improved. METHODS/PRINCIPAL FINDINGS: We conducted a study within rural villages in Tamil Nadu, India, which combines a household survey (28,494 people of snakebite incidence with a more detailed survey of victims in order to understand the health and socio-economic effects of the bite, the treatments obtained and their views about future improvements. Our survey suggests that snakebite incidence is higher than previously reported. 3.9% of those surveyed had suffered from snakebite and the number of deaths corresponds to 0.45% of the population. The socio-economic impact of this is very considerable in terms of the treatment costs and the long-term effects on the health and ability of survivors to work. To reduce this, the victims recommended improvements to the accessibility and affordability of antivenom treatment. CONCLUSIONS: Snakebite has a considerable and disproportionate impact on rural populations, particularly in South Asia. This study provides an incentive for researchers and the public to work together to reduce the incidence and improve the outcomes for snake bite victims and their families.

    Full Text Available Bacteriological analyses were carried out on Ananthanar channel water of Kanyakumari district, Tamil Nadu, India. The Ananthanar channel was selected in this study because this channel runs about nearly 28 km and supplies water for many villages for drinking and bathing purposes. Fecal and total coliform counts were performed using the standard membrane filtration technique and multiple tube technique. The results obtained were compared with reports of All India Institute of Medical Sciences Standards for Drinking and Recreational Water. Faecal coliform counts varied from 12 to 180 MPN/100 ml while Escherichia coli counts ranged from 6 to 161 MPN/100 ml for all the sampled sites. Among the total coliform Pseudomonas aeruginosa, Shewanella putrefaciens, Klebsiella pneumoniae, Citrobacter freundii and Proteus mirabilis are reported. The Faecal coliform and the E. coli counts exceeding acceptable limits are indicative of pollution from domestic wastes from several informal settlements located along the riverbank. Water uses in the area were determined and were found to be mainly domestic and recreational. The gross pollution of the river exposes the local people who depend on it for their primary water source to serious health risk.

    Hypertension is a public health problem with low detection and treatment rates in India. We resurveyed 1284 patients with hypertension already identified in baseline survey of the cohort in Thiruvallur district, Tamil Nadu, India. The objective was to estimate the proportion of patients with drug treatment, hypertension control and lifestyle modification at follow-up (median follow-up 27 months). Overall, only 19.9% of the patients took drugs and 45.3% had blood pressure under control. Among 256 patients on drugs, 179 (69.9%) were on a single drug, 71 (27.7%) on two drugs, and six (2.3%) on three drugs. Commonly prescribed drugs based on the prescription review were beta blockers (50.4%), calcium channel blockers (36.7%), angiotensin-converting-enzyme inhibitor (18.4%), and diuretics (11.7%). Salt reduction was reported by 49.7% of the patients. There is a need for strengthening the health systems for effective management of hypertension and patient education to ensure active involvement in the long-term care.

    2012-09-01

    Full Text Available In an endeavor to prioritize the conservation of marine environment, species that are threatened were given protection under various Schedules of the Indian Wildlife (Protection Act, 1972. Though the protection is sturdy on paper, marine fauna, such as sea shells, corals and sea horses are often illegally collected from their natural environment and are traded as marine curiosities. To assess those protected marine species in the curio trade in the state of Tamil Nadu, South India, certain major tourist and pilgrimage hot spots were surveyed during 2007. Among surveyed curio markets, Kanyakumari was found to have an alarming number of protected species being traded through huge number of marine curio shops. 15 species of legally protected mollusks, 10 species of corals and one sea horse species were found, along with other non-protected marine taxa in curio trade. Species protected through Schedule I were often highly priced than those under Schedule IV. The present survey suggests that protected marine species are an integral part in the growing marine curio business. High market demand, coupled with a lack of awareness and an inadequate enforcement were found to be major driving forces for the illegal marine curio trade. Awareness campaigns, along with a promotion of viable and alternate sources of income for seashell / coral collectors and strengthening of law enforcement may curtail the illegal marine curio trade.

    Full Text Available Abstract Background Avahan, the India AIDS Initiative, a large-scale HIV prevention program, using peer-mediated approaches and STI services, was implemented for high-risk groups for HIV in six states in India. This paper describes the assessment of the program among female sex workers (FSWs in the southern state of Tamil Nadu. Methods An analytical framework based on the Avahan impact evaluation design was used. Routine program monitoring data, two rounds of cross-sectional biological and behavioural surveys among FSWs in 2006 (Round 1 and 2009 (Round 2 and quality assessments of clinical services for sexually transmitted infections (STIs were used to assess trends in coverage, condom use and prevalence of STIs, HIV and their association with program exposure. Logistic regression analysis was used to examine trends in intermediate outcomes and their associations with intervention exposure. Results The Avahan program in Tamil Nadu was scaled up and achieved monthly reported coverage of 79% within four years of implementation. The cross-sectional survey data showed an increasing proportion of FSWs being reached by Avahan, 54% in Round 1 and 86% in Round 2 [AOR=4.7;p=0.001]. Quality assessments of STI clinical services showed consistent improvement in quality scores (3.0 in 2005 to 4.5 in 2008. Condom distribution by the program rose to cover all estimated commercial sex acts. Reported consistent condom use increased between Round 1 and Round 2 with occasional (72% to 93%; AOR=5.5; p=0.001 and regular clients (68% to 89%; AOR=4.3; p=0.001 while reactive syphilis serology declined significantly (9.7% to 2.2% AOR=0.2; p=0.001. HIV prevalence remained stable at 6.1% between rounds. There was a strong association between Avahan exposure and consistent condom use with commercial clients; however no association was seen with declines in STIs. Conclusions The Avahan program in Tamil Nadu achieved high coverage of FSWs, resulting in outcomes of improved

    The southern Indian state of Tamil Nadu has experienced a dramatic decline in fertility, accompanied by a trend of increased son preference. This paper reports on findings from qualitative interviews with women in rural villages about their fertility decision-making. Specifically addressed are the reasons behind increasing son preference and the consequences of this change. Findings suggest that daughter aversion, fuelled primarily by the perceived economic burden of daughters due to the proliferation of dowry, is playing a larger role in fertility decision-making than son preference. The desire for a son is often trumped by the worry over having many daughters. Women use various means of controlling the sex of their children, which in this study appear to be primarily female infanticide. It is important to distinguish between son preference and daughter aversion and to examine repercussions of low fertility within this setting.

    Variation in metal contamination in six species of birds, namely the Cormorant (Phalacrocorax carbo), Cattle Egret (Bubulcus ibis), Little Egret (Egretta garzetta), Pond Heron (Ardeola grayii), Common Myna (Acridotheres tristis) and Jungle Babbler (Turdoides striatus) in Nilgiris district, Tamil Nadu, India. The accumulation of heavy metals differed among the species studied. On an average, Little Egret accumulated high concentrations of copper (53.31 ± 23.19 ppm) followed by Cattle Egret (16.27 ± 9.83 ppm) in liver. Of all the species, Jungle Babbler recorded the maximum concentrations (20.59 ± 9.07 ppm) in muscle. The Pond Heron recorded the maximum concentration (35.38 ± 11.14 ppm) in brain. On an average the maximum level was in the kidney of Common Myna (7.76 ± 1.80 ppm).

    A total of 1377 tribals, comprising Irulas (536), Paniyas (196), Kurumbas (87), Mullukrurumbas (156) and Soligas (402), living in the Nilgiris, Tamil Nadu, India were studied for sickle cell trait between 1981-85. Patients attending various tribal clinics at Arayure, Kozhikarai, Kothagiri and Biligiri Rengan hills for various ailments were screened at random by solubility test and by acetate paper electrophoresis, if required. HbAS carrier frequency was 30-37.8 per cent in all the tribals studied except Kurumbas (19.5%). The frequency of carriers were more (37.8%) on the western part of Nilgiris (Nedungode, Kappala and adjoining regions) than the eastern part (30%). Further, the prevalence of carriers was higher (47-49%) in the 10-19 yr age group amongst Paniyas and Mullukurumbas living in the western part of Nilgiris. An episodic, epidemic of malaria so rampant during the early part of this century in the western parts of Nilgiris might have eliminated many children with HbAA and hence the higher frequency of HbAS in this particular age group.

    A potent Streptomyces bacillaris strain RAM25C4 was isolated for controlling methicillin-resistant Staphylococcus aureus and multidrug-resistant bacteria such as Staphylococcus aureus, Acinetobacter baumannii, and Pseudomonas aeruginosa. A total of 131 actinomycetes were isolated from the Rameswaram coastal region, Tamil Nadu, India. Among 131 actinomycetes, maximum number of actinomycetes (55%) isolated at the distance of 3-6 m from seashore. Out of 131 actinomycetes, 85% of the actinomycetes exhibited different degree of antagonistic activity against test pathogens. The antagonistic activity evaluated using actinomycetes direct culture filtrate and culture filtrate extracts. Among these culture filtrate, extracts had supreme antagonistic activity against multidrug-resistant bacteria and the solvent ethyl acetate was the best for extracting secondary metabolites from actinomycetes. In HPTLC analysis, the presence of macrolides, terpenoids, and quinolones was identified in RAM25C4 extract. In GC-MS analysis, various potent compounds such as phenolic compound-2,6-di-tert-butylphenol, alkaloid compound-1H, 5H, pyrrolo (1' 2':3, 4) imidazo, and quinolone compound-1,4-benzenediol, 2,5-bis(1,1-dimethylethyl) were identified in the ethyl acetate extract of RAM25C4. The phylogenetic analysis of 16S rRNA gene sequence of RAM25C4 isolate was deposited in NCBI with name Streptomyces bacillaris strain RAM25C4 and accession number KM513543.

    Here the rodent carrier status for the transmission of human leptospirosis in Tiruchirappalli, district, Tamil Nadu, India was assessed. The predominantly circulating leptospiral STs were recognized by multilocus sequence typing (MLST). A total of 113 rodents were trapped from different provinces of the Tiruchirappalli district. The most prevalent rodent was Bandicota bengalensis (37.2%), and of the total, 52.2% (n=59) rodents were found to be positive for leptospiral 16S rRNA. These results were validated with a leptospiral culture positivity of 45.8% (n=27). Three isolates from Chennai (2 rodents and 1 human) and 1 human isolate from Tiruchirappalli were included to understand the spatial variations and to track the source of human leptospirosis. The serogroup, serovar, and species level identification of all 31 isolates identified 28 to be Leptospira borgpetersenii serovar Javanica and three as Leptospira interrogans serovar Autumnalis. MLST analysis defined all isolates to the existing ST profiles (ST145 and ST27) with the exception of 6 L. borgpetersenii (ST DR) isolates that showed variations in the sucA and pfkB loci. The DR ST was locally confined to Chatram province of Tiruchirappalli suggesting an epidemiological link. The predominant STs, ST145 and ST-DR form a group, indicating the presence of original strain that subsequently diverged evolutionarily into two STs. The variations between L. borgpetersenii in sucA and pfkB loci may be an indication that evolutionary changes transpired in Tiruchirappalli.

    This paper deals with the spatial distribution and diversity of macrobenthos and their relationships between physico-chemical parameters of the water and sediment in different mangrove habitats of Tamil Nadu, India during different seasons (2008). Among the different ecosystems of mangrove benthic faunal assemblages, macrofauna species number, density, richness, and Shannon-Wiener index were the highest and the Simpson dominance index was medial at riverine mangrove community. However, the Pielou Evenness index of riverine mangrove community was slightly lower than other communities. The similarities among the macrobenthic communities at different sampling sites were determined using Bray-Curtis similarity coefficient and ordinations of non-metric multidimensional scaling (MDS). Thirty-one species were recorded in developing (16 polychaetes, six bivalves, seven gastropods, and two crustaceans), 35 species were recorded in riverine (20 polychaetes, six bivalves, five gastropods, and four crustaceans) and 31 species were recorded in island mangrove ecosystem (19 polychaetes, four bivalves, five gastropods, and three crustaceans). Among the three ecosystems, a total of 46 benthic macrofauna consisting of 27 species of polychaetes, eight species of gastropods, seven species of bivalves, and four species of crustaceans were recorded. However, there were obvious differences among the community structures in the three mangrove habitats. This result implied that the different mangrove ecosystem had different effects on the macrofauna communities and shed light on the macrofauna adaptation capability to specific habitats.

    HLA-A, B antigen and haplotype frequencies were studied in four different caste groups of Tamil Nadu living in Madurai. A total number of 101 Nadars, 36 Kallars, 54 Iyers and 57 Telugu-speaking Naidus were studied. HLA A3 and B15 were significantly higher in Nadars; A10 & B8 in Kallars and Aw19, B12 & B35 in Iyers. HLA A-B haplotypes A10-B7, A28-B17 & A24-B- were characteristic of Nadars; A10-B8 & A1-B-, Kallars; Aw19-B12 & A1-B15, Iyers and A2-B-, Naidus. Negative linkage disequilibria for Aw19-B7, A28-B15 & A9-B51 were significant in Nadars; A1-B5, A1-B12 & Aw19-B- in Iyers and A2-B17 in Naidus. Heterogeneity chi-square based on antigen frequency and genetic distance also suggest the heterogeneous nature of the population of South India. Will these caste groups with such diverse haplotypic combinations differ from one another in their immune response and susceptibility to a given epidemic or infection?

    Full Text Available Background: The burden of cancer is growing globally and is one of the top leading causes of death. Information on cancer patterns is essential for effective planning of cancer control interventions. Aims and Objectives: The present cross sectional study aims to explore the patterns and trends of the cancer incidences in the western regions of Tamil Nadu, India including Coimbatore, Erode, Tiruppur, Salem, Namakkal and Nilgiris. Materials and Methods: A sum of 14392 cancer cases were recorded from the hospital based cancer registries of Coimbatore district. The cancer cases were segregated district-wise for specific cancer sites and the age-standardized incident rates were calculated for different age groups. Results: Coimbatore district recorded the highest number of incidences among all districts. Among all age-groups the adults aged 50-74 carry the highest burden of cancer. Among men, head and neck and gastrointestinal cancers are predominant while among women, breast and gynecological cancers are high. The age-standardized incidence rates were found to be higher in Coimbatore and least in Salem. Conclusion: Through this study, it is observed that Coimbatore district is under major threat and needs further investigation of risk factors for implementing optimized treatment and prevention strategies for reducing the adverse effects of cancer.

    Full Text Available A study was conducted on the distribution of catfishes in selected wetlands in Kancheepuram and Kanyakumari districts of Tamil Nadu, southern India. Different types of wetlands such as tanks, pools, lakes, open wells and estuaries were selected for the study based on their different environmental set up. Fishes were collected with the help of fishermen using cast and seine nets. Twelve species of catfishes from five families (Ariidae, Bagridae, Heteropneustidae, Schilbeidae and Siluridae were recorded, of which 10 species from four families were from Kanyakumari and six species belonging to three families were from Kancheepuram District. In Kancheepuram, the species recorded were Heteropneustes fossilis, Mystus seengtee, M. gulio, M. keletius, M. vittatus and Neotropius atherinoides, and in Kanyakumari the species recorded were Arius arius, Arius subrostratus, Heteropneustes fossilis, Mystus armatus, M. seengtee, M. gulio, M. montanus, M. vittatus, Ompok bimaculatus and O. malabaricus. Among the wetlands, the highest species richness was seen in Puthery and Erachakulam tanks in Kanyakumari and Chembarampakkam Lake in Kancheepuram. The lowest species richness was observed was in Vishnupuram, Thotiode tanks and Mavadi pool of the former district and Vandalur Tank, Kalpakkam Estuary of the latter. Environmental factors such as microhabitat diversity and substrate diversity in the wetlands significantly influenced species richness.

    Compressional and shear wave velocities and attenuation measurements have been carried out in some of the borehole samples of acidic, basic and intermediate granulites of Mahabalipuram, Tamil Nadu, India. The results have been obtained at ambient conditions using ‘time-of-flight’ pulse transmission technique at 1.0MHz frequency. The results show linear relationships between velocity and density, and velocity and attenuation properties of the rocks. The acidic granulites show lower velocities and higher attenuation than the intermediate and basic granulites. The average values of the Poisson’s ratio of acidic, intermediate and basic granulites have been found to be 0.210, 0.241 and 0.279 respectively. The variations in velocities and attenuation in these low porosity crystalline rocks are found to be strongly influenced by their mineral composition. The laboratory velocity data (extrapolated to high pressure) of the present study and the published field velocity data from deep seismic sounding studies indicate that these granulite facies rocks may belong to mid-crustal depths only.

    Full Text Available Livestock keepers comprise 2/3rds of the 2.8 billion households living on less than two dollars per day. However, as a group they tend to be marginalised and excluded from formal service provision, particularly in relation to animal health. Therefore, the following paper describes the development of the Livestock Guru, a multi-media learning programme created to meet the knowledge needs of poor livestock keepers in Tamil Nadu, India. The findings from the study illustrate the importance of both appropriate visuals, voice-overs but also the need for addressing issues in the environment in which learning will take place.

    To determine the susceptibility of female eye hospital staff to rubella infection and the potential risk for hospital-based rubella outbreaks. A prospective cohort study on the seroprevalence of rubella IgG antibodies was conducted at three large eye hospitals in Coimbatore, Madurai and Tirunelveli, Tamil Nadu, India, where young children with eye abnormalities attributable to congenital rubella are treated. A total of 1000 female hospital employees aged 18-40 years agreed to participate and gave written informed consent. The proportions of rubella-seronegative women were: 11.7% at Coimbatore, with a 95% confidence interval (CI) of 8.1-16.5; 15% at Madurai (95% CI = 12.3-18.1), and 20.8 at Tirunelveli (95% CI = 14.7-28.6). For the entire cohort the proportion seronegative was significantly higher among married women (21.5%) than among single women (14.0%) (P = 0.02). Rates of seronegativity were highest among physicians and lowest among housekeepers. All 150 seronegative women in the study sample accepted a dose of rubella vaccine. These are the first rubella serosurveys to have been reported from eye hospitals in any country. The relatively high rate of susceptibility indicated a risk of a rubella outbreak, and this was reduced by vaccinating all seronegative women. A policy has been established at all three hospitals for the provision of rubella vaccine to new employees. Other hospitals, especially eye hospitals and hospitals in countries without routine rubella immunization, should consider the rubella susceptibility of staff and the risk of hospital-based rubella outbreaks.

    Worldwide, coastal aquifers are threatened by seawater intrusion. The threat is greatest when aquifers are overexploited or when recharge is low due to a semi-arid or arid climate. The Kaluvelli-Pondicherry sedimentary basin in Tamil Nadu (India) presents both these characteristics. Groundwater levels in the Vanur aquifer can reach 50 m below sea level at less than 20 km inland. This groundwater depletion is due to an exponential increase in extraction for irrigation over 35 years. No seawater intrusion has yet been detected, but a sulphate-rich mineralization is observed, the result of upward vertical leakage from the underlying Ramanathapuram aquifer. To characterize the mechanisms involved, and to facilitate effective water management, hydrogeological numerical modelling of this multi-layered system has been conducted. Existing and acquired geological and hydrodynamic data have been applied to a quasi-3D hydrogeological model, NEWSAM. Recharge had been previously quantified through the inter-comparison of hydrological models, based on climatological and surface-flow field measurements. Sensitivity tests on parameters and boundary conditions associated with the sea were performed. The resulting water balances for each aquifer led to hypotheses of (1) an offshore fresh groundwater stock, and (2) a reversal and increase of the upward leakage from the Ramanathapuram aquifer, thus corroborating the hypothesis proposed to explain geochemical results of the previous study, and denying a seawater intrusion. Palaeo-climate review supports the existence of favourable hydro-climatological conditions to replenish an offshore groundwater stock of the Vanur aquifer in the past. The extent of this fresh groundwater stock was calculated using the Kooi and Groen method.

    Full Text Available Aim: To assess the prevalence of haemoprotozoan diseases in cross-bred and indigenous cattle in relation to season, age and breed in Western part of Tamil Nadu, India. Materials and Methods: A total of 2637 blood smears were screened for haemoprotozoan diseases and samples were received from the college hospital and veterinary dispensaries in Western part of Tamil Nadu, India. Blood smears were stained using Giemsa's technique and examined under oil immersion. Results: Microscopic examination of blood smears revealed an overall prevalence of 16.64 %; of which theileriosis was 13 %, followed by anaplasmosis 2.64 % and then babesiosis 1.0%. Among the haemoprotozoan diseases, the prevalence of theileriosis was significantly (p<0.05 high during summer (14.4%, followed by moderate in monsoon (13.8% and less in fair (11.5% seasons. However, there was no significant seasonal influence on the prevalence of babesiosis and anaplasmosis. The data on influence of breed revealed that there was a significantly (p<0.05 high prevalence of haemoprotozoan diseases in Holstein Friesian (HF and Jersey cross breeds than indigenous breed and the occurrence of these haemoprotozoan diseases was found to be high among the age groups of 2-7 years in cross-bred animals and below 2 years in indigenous animals. Conclusion: The present study suggests that Western part of Tamil Nadu is highly endemic for theileriosis and occurrence of the disease was high during summer. Cross-bred animals aged 2-7 years are highly susceptible to these haemoprotozoan diseases than indigenous animals.

    India's reputation as a country with a culture of abstinence especially in matters regarding alcohol is underserved. There has been a rapid proliferation of city bars and nightclubs in recent years and people are fast shedding its inhibitions about alcohol as a lifestyle choice. This scenario has led to fears of an undocumented rise in alcohol abuse among all sections of society. Policies by the government has been laid down to regulate sales and pricing of alcohol, but not well improvised. Our aim was to find out the prevalence of alcoholism among adult males in a rural population and also to analyze its association between various factors. A cross sectional study in a rural population at Kuthampakkam village, in Poonamallee block of Tiruvallur district in Tamil Nadu, India. The study population included adult male population. Simple random sampling method was adopted. A structured questionnaire was used to collect information regarding the background characteristics, history of alcoholism and certain social factors. Data entry and analysis was done using Statistical Package for Social Sciences (SPSS) version 15 software. Descriptive statistics were calculated for background variables and the prevalence of the alcoholism. Chi-square test and p-value were calculated to see the association between alcoholism and social factors. A total of 157 adult male were enrolled in the study. The mean age of the study participants was 37.20 years. The prevalence of alcoholism among the study participants was 35.7%. Among them only 4.5% who presented with symptoms of chronic alcoholism had taken treatment. Reasons for not taking treatment for alcoholism among study population were mainly due to their family problems (55.2%). Although alcohol consumption has existed for many centuries, the quantity, usage pattern, and resultant problems have undergone substantial changes over the past 20 years. These developments have raised concerns about the public health and social

    Fluorosis is one of the common but major emerging areas of research in the tropics. It is considered endemic in 17 states of India. However, the Cuddalore district of Tamil Nadu is categorised as a fluorosis non-endemic area. But clinical cases of dental fluorosis were reported in the field practice area of Department of Community Medicine, Rajah Muthiah Medical College, Annamalai University, Chidambaram. Since dental fluorosis has been described as a biomarker of exposure to fluoride, we assessed the prevalence and severity of dental fluorosis among primary school children in the service area. Children studying in six primary schools of six villages in the field practice area of Rural Health Centre of Faculty of Medicine, Annamalai University, Chidambaram, were surveyed. Every child was clinically examined at the school by calibrated examiners with Dean's fluorosis index recommended by WHO (1997). Chi-square test, Chi-square trend test and Spearman's rank correlation coefficient test were used for statistical analysis. Five hundred and twenty-five 5- to 12-year-old school children (255 boys and 270 girls) were surveyed. The overall dental fluorosis prevalence was found to be 31.4% in our study sample. Dental fluorosis increased with age P fluorosis was found in 2.1% of the sample. Villages Senjicherry, Keezhaperambai and Kanagarapattu revealed a community fluorosis index (CFI) score of 0.43, 0.54 and 0.54 with 5.6%, 4.8% and 1.4% of objectionable dental fluorosis, respectively. Correlation between water fluoride content and CFI values in four villages was noted to be positively significant. Three out of six villages studied were in 'borderline' public health significance (CFI score 0.4-0.6). A well-designed epidemiological investigation can be undertaken to evaluate the risk factors associated with the condition in the study region.

    India leads all nations in numbers of maternal deaths, with poor, rural women contributing disproportionately to the high maternal mortality ratio. In 2005, India launched the world's largest conditional cash transfer scheme, Janani Suraksha Yojana (JSY), to increase poor women's access to institutional delivery, anticipating that facility-based birthing would decrease deaths. Indian states have taken different approaches to implementing JSY. Tamil Nadu adopted JSY with a reorganization of its public health system, and Gujarat augmented JSY with the state-funded Chiranjeevi Yojana (CY) scheme, contracting with private physicians for delivery services. Given scarce evidence of the outcomes of these approaches, especially in states with more optimal health indicators, this cross-sectional study examined the role of JSY/CY and other healthcare system and social factors in predicting poor, rural women's use of maternal health services in Gujarat and Tamil Nadu. Using the District Level Household Survey (DLHS)-3, the sample included 1584 Gujarati and 601 Tamil rural women in the lowest two wealth quintiles. Multivariate logistic regression analyses examined associations between JSY/CY and other salient health system, socio-demographic, and obstetric factors with three outcomes: adequate antenatal care, institutional delivery, and Cesarean-section. Tamil women reported greater use of maternal healthcare services than Gujarati women. JSY/CY participation predicted institutional delivery in Gujarat (AOR = 3.9), but JSY assistance failed to predict institutional delivery in Tamil Nadu, where mothers received some cash for home births under another scheme. JSY/CY assistance failed to predict adequate antenatal care, which was not incentivized. All-weather road access predicted institutional delivery in both Tamil Nadu (AOR = 3.4) and Gujarat (AOR = 1.4). Women's education predicted institutional delivery and Cesarean-section in Tamil Nadu, while husbands

    Snakebites cause death, disability and economic devastation to their victims, people who live almost exclusively in rural areas. Annually an estimated two million venomous bites cause as many as 100,000 deaths worldwide as well as hundreds of thousands of deformities and amputations. Recent studies suggest that India has the highest incidence of snakebite and associated deaths worldwide. In this study, we interviewed 25 hospital-based clinicians who regularly treat snakebites in Tamil Nadu, India, in order to gauge their opinions and views on the diagnostic tools and treatment methods available at that time, the difficulties encountered in treating snakebites and improvements to snakebite management protocols they deem necessary. Clinicians identified the improvement of community education, training of medical personnel, development of standard treatment protocols and improved medication as priorities for the immediate future.

    In 2001, a major dengue outbreak was recorded in Chennai city, with 737 cases (90%) out of a total of 861 cases recorded from Tamil Nadu state. A KAP survey was carried out to assess the community knowledge, attitude and practice on dengue fever (DF), following the major dengue outbreak in 2001. A pre- tested, structured questionnaire was used for data collection. The multistage cluster sampling method was employed and 640 households (HHs) were surveyed. Among the total HHs surveyed, 34.5% of HHs were aware of dengue and only 3.3% of HHs knew that virus is the causative agent for DF. Majority of the HHs (86.5%) practiced water storage and only 3% of them stored water more than 5 days. No control measures were followed to avoid mosquito breeding in the water holding containers by majority of HHs (65%). Sixty percent of HHs did not know the biting behaviour of dengue vector mosquitoes. The survey results indicate that the community knowledge was very poor on dengue, its transmission, vector breeding sources, biting behavior and preventive measures. The lack of basic knowledge of the community on dengue epidemiology and vector bionomics would be also a major cause of increasing trend of dengue in this highly populated urban environment. There is an inevitable need to organize health education programmes about dengue disease to increase community knowledge and also to sensitize the community to participate in integrated vector control programme to resolve the dengue problem.

    Hospital and urban effluents contain a variety of toxic and/or persistent substances in a wide range of concentrations, and most of these compounds belong to the group of emerging contaminants. The release of these substances into the aquatic ecosystem can lead to the pollution of water resources and may place aquatic organisms and human health at risk. Sediments receiving untreated and urban effluent waters from the city of Tiruchirappalli in the state of Tamil Nadu, India, are analyzed for potential environmental and human health risks. The sediment samples were collected from five hospital outlet pipes (HOP) and from the Cauvery River Basin (CRB) both of which receive untreated municipal effluent waters (Tiruchirappalli, Tamil Nadu, India). The samples were characterized for grain size, organic matter, toxic metals, and ecotoxicity. The results highlight the high concentration of toxic metals in HOP, reaching values (mg kg(-1)) of 1851 (Cr), 210 (Cu), 986 (Zn), 82 (Pb), and 17 (Hg). In contrast, the metal concentrations in sediments from CRB were lower than the values found in the HOP (except for Cu, Pb), with maximum values (mg kg(-1)) of 75 (Cr), 906 (Cu), 649 (Zn), 111 (Pb), and 0.99 (Hg). The metal concentrations in all sampling sites largely exceed the Sediment Quality Guidelines (SQGs) and the Probable Effect Concentration (PEC) for the Protection of Aquatic Life recommendation. The ecotoxicity test with ostracods exposed to the sediment samples presents a mortality rate ranging from 22 to 100 % (in sediments from HOP) and 18-87 % (in sediments from CRB). The results of this study show the variation of toxic metal levels as well as toxicity in sediment composition related to both the type of hospital and the sampling period. The method of elimination of hospital and urban effluents leads to the pollution of water resources and may place aquatic organisms and human health at risk.

    Full Text Available Afforestation becomes essential to conserve and increase the forest area. Mangroves have many endangered species which requires conservation. During afforestation, the species encounters different edaphic and environmental factors. For adopting the new environment, the introduced species tend to change its morphological and physiological characters. To study the variation between the species at natural and afforested habitats, the following species were selected i.e., Rhizophora apiculata, Rhizophora mucronata, Bruguiera cylindrica and Ceriops decandra at the Pichavaram Mangrove forest and Mulukuturai (afforested area mudflat of Tamil Nadu, India. Variation has been analyzed using RAPD and found there are variations between the species in the natural habitat itself at various degrees and no significant variation found within plants of natural habitat and afforested habitat, showing that these species are well adopted for afforestation in new areas like mudflats.

    Full Text Available Background: Fluorosis is one of the common but major emerging areas of research in the tropics. It is considered endemic in 17 states of India. However, the Cuddalore district of Tamil Nadu is categorised as a fluorosis non-endemic area. But clinical cases of dental fluorosis were reported in the field practice area of Department of Community Medicine, Rajah Muthiah Medical College, Annamalai University, Chidambaram. Since dental fluorosis has been described as a biomarker of exposure to fluoride, we assessed the prevalence and severity of dental fluorosis among primary school children in the service area. Materials and Methods: Children studying in six primary schools of six villages in the field practice area of Rural Health Centre of Faculty of Medicine, Annamalai University, Chidambaram, were surveyed. Every child was clinically examined at the school by calibrated examiners with Dean′s fluorosis index recommended by WHO (1997. Chi-square test, Chi-square trend test and Spearman′s rank correlation coefficient test were used for statistical analysis. Results: Five hundred and twenty-five 5- to 12-year-old school children (255 boys and 270 girls were surveyed. The overall dental fluorosis prevalence was found to be 31.4% in our study sample. Dental fluorosis increased with age P < 0.001, whereas gender difference was not statistically significant. Aesthetically objectionable dental fluorosis was found in 2.1% of the sample. Villages Senjicherry, Keezhaperambai and Kanagarapattu revealed a community fluorosis index (CFI score of 0.43, 0.54 and 0.54 with 5.6%, 4.8% and 1.4% of objectionable dental fluorosis, respectively. Correlation between water fluoride content and CFI values in four villages was noted to be positively significant. Conclusion: Three out of six villages studied were in ′borderline′ public health significance (CFI score 0.4-0.6. A well-designed epidemiological investigation can be undertaken to evaluate the risk factors

    Soil is a complex and dynamic biological system. Agroforestry systems are considered to be an alternative land use option to help and prevent soil degradation, improve soil fertility, microbial diversity, and organic matter status. An increasing interest has emerged with respect to the importance of microbial diversity in soil habitats. The present study deals with the status of microbial diversity in agroforestry systems in Tamil Nadu. Eight soil samples were collected from different fields in agroforestry systems in Cuddalore, Villupuram, Tiruvanamalai, and Erode districts, Tamil Nadu. The number of microorganisms and physico-chemical parameters of soils were quantified. Among different microbial population, the bacterial population was recorded maximum (64%), followed by actinomycetes (23%) and fungi (13%) in different samples screened. It is interesting to note that the microbial population was positively correlated with the physico-chemical properties of different soil samples screened. Total bacterial count had positive correlation with soil organic carbon (C), moisture content, pH, nitrogen (N), and micronutrients such as Iron (Fe), copper (Cu), and zinc (Zn). Similarly, the total actinomycete count also showed positive correlations with bulk density, moisture content, pH, C, N, phosphorus (P), potassium (K), calcium (Ca), copper (Cu), magnesium (Mg), manganese (Mn), and zinc (Zn). It was also noticed that the soil organic matter, vegetation, and soil nutrients altered the microbial community under agroforestry systems.

    This paper describes the projection of climate change scenarios under increased greenhouse gas emissions, using the results of atmospheric-ocean general circulation models in the Coupled Model Intercomparison Project phase 3 dataset. A score is given to every model based on global and regional performance. Four out of 20 general circulation models (GCMs) were selected based on skill in predicting observed annual temperature and precipitation conditions. The ensemble of these four models shows superiority over the individual model scores. These models were subjected to increases in future anthropogenic radiative forcings for constructing climate change scenarios. Future climate scenarios for Tamil Nadu were developed with MAGICC/SCENGEN software. Model results show both temperature and precipitation increases under increased greenhouse gas scenarios. Northeast and northwest parts of Tamil Nadu show a greater increase in temperature and precipitation. Seasonally, the maximum rise in temperature occurred during the MAM season, followed by DJF, JJA, and SON. Decreasing trends of precipitation were observed during DJF and MAM.

    The millions of food insecure people in India are not solely due to inadequate food production, but also because some people are simply too poor to buy food. This study assessed how a large-scale conversion from conventional to organic production would impact on the economics of marginal and small...... farmers in Tamil Nadu and Madhya Pradesh, and on the total food production in these states. This study also considered a situation where fertilizer subsidies would be discontinued, with farmers having to carry the full cost of fertilizer. Results show that conversion to organic improved the economic...... situation of farmers although food production was reduced by 3-5% in the organic situation. Thus, the estimated economic values were higher in the organic system (5-40% in fertilizer subsidy scenario and 22-132% in no fertilizer subsidy scenario) than in the conventional system, whereas the total state...

    Radiation exposure and effective dose received through two routes of exposure, viz. external and internal, via inhalation, by residents of 10 villages belonging to Natural High Background Radiation Areas (NHBRA) of coastal regions of Kanyakumari District and Tamil Nadu in India were studied. While the indoor gamma radiation levels were monitored using Thermo Luminescent Dosimeters (TLDs), the indoor radon and thoron gas concentrations were measured using twin chamber dosimeters employing Solid State Nuclear Track Detectors (SSNTDs, LR-115-II). The average total annual effective dose was estimated and found to be varying from 2.59 to 8.76 mSv. -- Highlights: {yields} The effective dose received by the villages of Natural High Background Area (NHBRA) such as Enayam, Midalam and Mel Midalam is high when compared with other study areas. {yields} The high dose indicates higher concentration of radioactive nuclides like Thorium and Uranium in the soil. {yields} As radiation is harmful to human life, the external and internal doses can be reduced by removing the monazite content present in the soil by mineral separation. {yields} Contribution from vegetables, fruits, fish and other non vegetarian items are also being examined. {yields} These results along with other socio-economic factors can throw considerable light on the epidemiological impacts due to low levels of chronic exposure.

    The basis of the present study was to distinguish the existence of any genetic variability among populations of Culex quinquefasciatus which would be a valuable tool in the management of mosquito control programmes. In the present study, population of Cx. quinquefasciatus collected at different locations in Tamil Nadu were analyzed for their genetic variation based on 28S rDNA D2 region nucleotide sequences. A high degree of genetic polymorphism was detected in the sequences of D2 region of 28S rDNA on the predicted secondary structures in spite of high nucleotide sequence similarity. The findings based on secondary structure using rDNA sequences suggested the existence of a complex genotypic diversity of Cx. quinquefasciatus population collected at different locations of Tamil Nadu, India. This complexity in genetic diversity in a single mosquito population collected at different locations is considered an important issue towards their influence and nature of vector potential of these mosquitoes.

    Cretaceous phosphorites from the onshore of Tamil Nadu have been investigated for their origin and compared with those in the offshore. Cretaceous phosphorites occur as light brown to yellowish brown or white nodules in Karai Shale of the Uttatur Group in the onshore Cauvery basin. Nodules exhibit phosphatic nucleus encrusted by a chalky shell of carbonate. The nucleus of the nodules consists of light and dark coloured laminae, phosphate peloids/coated grains and detrital particles interspersed between the laminae. Scanning electron microscope (SEM) studies reveal trapping and binding activity of microbial filaments. A mat structure with linearly arranged microbial filaments and hollow, cell-based coccoid cyanobacterial mat are present. Nodules contain abundant carbonate fluorapatite, followed by minor calcite, quartz and feldspar. The P2O5 content of the phosphorites ranges from 18 to 26%. The CaO/P2O5, Sr and F contents are higher than that of pure carbonate fluorapatite. Concentrations of Si, Al, K, Fe, and Ti are low. We suggest that the nuclei of the nodules represent phosphate clasts related to phosphate stromatolites formed at intertidal conditions. At high energy levels the microbial mats were disintegrated into phosphate clasts, coated with carbonate and then reworked into Karai Shale. On the other hand, Quaternary phosphorites occur as irregular to rounded, grey coloured phosphate clasts at water depths between 180 and 320m on the continental shelf of Tamil Nadu. They exhibit grain-supported texture. Despite Quaternary in age, they also resemble phosphate stromatolites of intertidal origin and reworked as phosphate clasts onto the shelf margin depressions. Benthic microbial mats probably supplied high phosphorus to the sediments. Availability of excess phosphorus seems to be a pre-requisite for the formation of phosphate stromatolites.

  17. ‘Too many girls, too much dowry’: son preference and daughter aversion in rural Tamil Nadu, India

    2013-01-01

    The southern Indian state of Tamil Nadu has experienced a dramatic decline in fertility, accompanied by a trend of increased son preference. This paper reports on findings from qualitative interviews with women in rural villages about their fertility decision-making. Specifically addressed are the reasons behind increasing son preference and the consequences of this change. Findings suggest that daughter aversion, fuelled primarily by the perceived economic burden of daughters due to the proliferation of dowry, is playing a larger role in fertility decision-making than son preference. The desire for a son is often trumped by the worry over having many daughters. Women use various means of controlling the sex of their children, which in this study appear to be primarily female infanticide. It is important to distinguish between son preference and daughter aversion and to examine repercussions of low fertility within this setting. PMID:18821352

    This study assessed if pre disaster, with-in disaster and post disaster factors predicted Post Traumatic Stress Disorder (PTSD) differently, among men and women survivors of the 2004 Southeast Asian tsunami in Kanyakumari district, Tamil Nadu, India. PTSD was identified using a validated tool, Impact of Events Scale-Revised (IES-R) among the participants in a cross-sectional community based survey (n=485). Case control analysis of 299 subjects was done to determine the predictors of PTSD. The odds of having PTSD were 6.35 times higher in women than men. Higher odds for PTSD was seen among women who were married, aged over 40, belonged to low socioeconomic status and resided in heavily damaged areas. Protective odds for PTSD was found among women who had received more than three times of counseling services whereas men were not at risk if they were free from fear of recurrence of tsunami, when adjusted for other variables. Women were vulnerable to PTSD because of their socially constructed roles. It is important to consider gender based vulnerabilities while designing interventions to combat mental health problems among disaster affected communities. Copyright © 2016 Elsevier B.V.

    Objective: To conduct an ethnobotanical studies and collect information about the wild edible plants collected and utilized by the Irula tribes of Pillur valley, Coimbatore District, Tamil Nadu, India. Methods: The study was conducted among the Irula peoples of Pillur valley through survey, interview and field work along with the knowledgeable individuals during January 2009 -September 2010. All the traditional and other knowledge related to the collection and consumption of wild edible plants on which the communities depend was documented. Results: A total of 74 plant species have been recorded as wild edible in the study areas, of which, fruits yielding plants ranked first with 42 species, green leaves, tubers, young shoots and flowers ranked next with 26, 7, 4 and 2 species respectively. Conclusions: Our study revealed that the adivasi community in the Pillur Valley continues to have and use the knowledge about the wild edible plants, including their habitat, collection period, sustainable collection, mode of preparation and consumption. To date, this knowledge appear to be fairly well conserved and used as a result of continued reliance of local community on the wild uncultivated foods.

    Listeria monocytogenes, an important bacterial pathogen, is responsible for foodborne illnesses worldwide. Examination of food samples for the presence of L. monocytogenes and assessment of their pathogenicity is usually an effective strategy in the prevention of listeriosis. In the present study, we have tested 307 samples of milk and milk products from various places in Tamil Nadu, India for the presence of L. monocytogenes using ISO 11290 and U.S. Food and Drug Administration Bacteriological Analytical Manual methods. 16S rDNA sequencing and duplex polymerase chain reaction (PCR) analysis for prs and iap genes were used to identify L. monocytogenes at the species level. Fifteen of the 307 samples screen tested positive for L. monocytogenes. Molecular serotyping of the L. monocytogenes isolates by multiplex PCR revealed the predominance of the serogroups 1/2a and 4b. Fourteen of the 15 isolates contained all the virulence genes (inlA, inlB, hlyA, and plcA) screened for using multiplex PCR. Only one isolate of L. monocytogenes was negative for the plcA gene and in vitro phosphatidylinositol-phospholipase C activity. L. monocytogenes strains that belong to the serogroup 4b exhibited higher nematocidal activity against Caenorhabditis elegans than the serogroup 1/2a. Worms infected with L. monocytogenes were symptomatic with aberrant contraction of body muscles, loss of pharyngeal pumping, and decreased locomotion, which highlights the pathogenic potential of the L. monocytogenes isolates.

    Biological monitoring and assessment studies due to urban--rail road pollutants were carried out using Air Pollution Tolerance Index (APTI) of plants. Four plant (leaf) parameters--namely ascorbic acid, total chlorophyll, relative water content and leaf extract pH were combined together in a formulation signifying the APTI of plants. APTI was calculated for five different species such as Azadirachta indica, Delonix regia, Ficus religiosa, Pongamia pinnata and Polyalthia longifolia growing in two different areas, i.e. control area and along the railway track of Madurai, Tamil Nadu (India). The control site was selected in the college campus. None of the four plant parameters indicated a consistent response to pollutants. In the present study, Delonix regia and Pongamia pinnata lost the tolerance towards air pollutants and became more sensitive, but Azadirachta indica, Ficus religiosa, and Polyalthia longifolia indicated high APTI values over control area and hence considered as tolerant species. The APTI of plants showed a marked gradation as the pollutant load decreased from rail road to control area. The APTI can be used as a good indicator of impact of the air pollution on plants.

    The aim of the present research was to investigate the seasonal impact on nearshore beach dynamics and the status of heavy mineral distribution along central Tamil Nadu coast, India. Beach profile measurements were made in 10 profiling sites between Thirukadaiyur and Velankanni on monthly and seasonal basis from January 2011 to July 2012. Using beach profile data, variation in beach width, slope and volumetric changes have been calculated. Beach slope and nearshore wave parameters were used to quantify the longshore sediment transport rate. Beaches between Thirukadaiyur and Karaikkal attained predominant transport rate in northern direction whereas, the rest of the beaches are in southern direction. The seasonal action of wind and wave currents create nearshore bar during northeast (NE) monsoon and frequent berms at tidal zone during southwest (SW) monsoon. Surface sediment samples were collected in each location for quantifying the heavy mineral weight percentage during the period of pre- and post-Thane cyclone. Sediments were also studied by X-ray diffraction (XRD) to evaluate the changes and occurrence of heavy minerals in beach sands. The XRD results show that sediments in the study area have enriched heavy mineral distribution even after strong cyclonic event. It confirms the redistribution of heavy mineral deposits present in the coast. The results suggested that monsoonal action has influenced the seasonal changes in beach morphology and it does not affect the heavy mineral distribution.

    A distinct bipartite begomovirus was found to be associated with the mosaic disease on ivy gourd (Coccinia grandis L.) in Tamil Nadu, India. The complete DNA A and DNA B components were cloned by rolling circle amplification. Genome organization of this virus is found to be typical of Old World bipartite begomovirus. The association of betasatellite component with this virus is absent. The closest nucleotide identity of 73.4 % was seen with the Loofa yellow mosaic virus (LYMV-[VN]-AF509739) suggesting that it is a new virus species Coccinia mosaic virus (CoMoV-Ivy gourd [TN TDV Coc1]) and distantly related to the other known begomoviruses. The DNA B component shared a maximum identity of 55 % with that of Tomato leaf curl New Delhi virus (ToLCNDV). In the phylogenetic analysis, CoMoV-Ivy gourd form cluster separate from other begomoviruses. Recombination analysis showed that there was no recombination event in the genome. This is the distinct begomovirus infecting ivy gourd.

    The natural level of radioactivity in building materials is one of the major causes of external exposure to γ-rays. The primordial radionuclides in building materials are one of the sources of radiation hazard in dwellings made of these materials. By the determination of the radioactivity level in building materials, the indoor radiological hazard to human health can be assessed. This is an important precautionary measure whenever the dose rate is found to be above the recommended limits. The aim of this work was to measure the specific activity concentration of (226)Ra, (232)Th and (40)K in commonly used building materials from Namakkal, Tamil Nadu, India, using gamma-ray spectrometer. The radiation hazard due to the total natural radioactivity in the studied building materials was estimated by different approaches. The concentrations of the natural radionuclides and the radium equivalent activity in studied samples were compared with the corresponding results of different countries. From the analysis, it is found that these materials may be safely used as construction materials and do not pose significant radiation hazards.

    The combined studies on grain size distribution, organic matter contents of sediments, sequential extraction and bulk concentration of heavy metals, statistical analysis, and ecological risk assessments were carried out to investigate the contamination sources and ecological risks of surface sediments at Coleroon River Estuary in Tamil Nadu, India. The sequential extraction of metals showed that a larger portion of the metals was associated with the residual phase and also in other fractions. The low concentrations of heavy metals were found in exchangeable and carbonate bounds (bioavailable phases). It revealed that sediments of Coleroon River Estuary were relatively unpolluted and were influenced mainly by natural sources. The observed order of bulk concentrations of heavy metals in the sediments was as follows: Fe > Mn > Zn > Cu > Pb > Cr > Ni > Co. Factor analyses represented that the enrichment of heavy metals was mostly resulted from lithogenic origins associated with anthropogenic sources. These sources were reconfirmed by cluster analysis. Risk assessment code (RAC) suggested that all metals were not harmful in monsoon season. However, Fe was in medium risk, and Mn and Cu were in low risk in summer. According to pollution load index (PLI) of sediments, all heavy metals were toxic. Cu might be related with adverse biological effects on the basis of sediment quality guidelines (SQG) in both seasons. These integrated approaches were very useful to identify the contamination sources and ecological risks of sediments in estuarine environment. It is expected that this research can give a useful information for the remediation of heavy metals in sediments.

    Studies have shown that social capital is positively associated with health, and the association is context-based. Indigenous populations with poor access to health care largely depend on social capital for their health care needs. This study was conducted to explore the dimensions and types of social capital and its utilization by families with thalassemia for their health and well-being in an indigenous population in Tamil Nadu, India. The participants in the study were parents who had children with thalassemia, belonged to an indigenous community in Tamil Nadu, were poor and marginalized, and had poor access to health care. Different dimensions and types of social capital were examined with the help of qualitative in-depth interviews using a phenomenological approach. A total of 8 in-depth interviews were conducted and transcribed. Thematic analysis of the data was performed. The social capital identified through the in-depth interviews consisted of various levels of family support, financial support from relatives and neighbors, the provision of information from formal and informal networks, and trust in the physician. Indigenous communities are close-knit due to their geographical remoteness and limited accessibility. Family ties were a form of social capital that encouraged bonding, and provided support and care to the children affected by thalassemia. The bonding also helped to meet the regular requirement of blood donation for the children. Relatives and neighbors were an asset that served as a bridge for the families affected, helping them in times of immediate and urgent financial need, making it easier to sustain long-term treatment and providing emotional support. There were informal networks that bridged parents belonging to indigenous and non-indigenous communities, with the latter providing the former with information to help them choose better health care at an affordable cost. The other formal links were the ties between the parents and

    Groundwater quality is important as it is the main factor determining its suitability for drinking, domestic, agricultural and industrial purposes. The suitability of groundwater for drinking and irrigation has been assessed in north and eastern part of Krishnagiri district, South-western part of Vellore district and contiguous with Andhra Pradesh states, India. A total of 31 groundwater samples were collected in the study area. The groundwater quality assessment has been carried out by evaluating the physicochemical parameters such as pH, EC, TDS, HCO3^{ - } , Cl-, SO4^{2 - } , Ca2+, Mg2+, Na+ and K+. The dominant cations are in the order of Na+ > K+ > Ca2+ > Mg2+ while the dominant anions have the trends of Cl- > HCO3^{ - } > SO4^{2 - } > CO3. The quality of the water is evaluated using Wilcox diagram and the results reveals that most of the samples are found to be suitable for irrigation. Based on these parameters, groundwater has been assessed in favor of its suitability for drinking and irrigation purpose.

    Full Text Available Summary. We investigated the relationship between child marriage among young women and their level of empowerment with spousal physical violence in two culturally distinct states of India (Bihar and Tamil Nadu using nationally representative survey data. Empowerment index was calculated taking into account parameters such as mobility, economic independence, and decision-making power of a woman using Principal Component Analysis method. Lower level of women empowerment was significantly associated with physical violence in Tamil Nadu (OR = 2.38, p<0.01 whereas marriage before the age of 15 was associated with physical violence in Bihar (OR = 3.27, p<0.001. The mean age at marriage was low among women who reported physical violence as compared to those who did not report physical violence across Bihar and Tamil Nadu and at all India level. Although the majority of the women in Tamil Nadu justified wife beating and witnessed father beating mother as compared to the women from Bihar, however, they were less likely to report physical violence than women from Bihar. Factors contributing to physical violence are distinct in Bihar and Tamil Nadu. Culture specific intervention may be considered while planning intervention strategies to curb spousal violence against women.

    The susceptibility status of Xenopsylla cheopis, the efficient vector of human plague in India was assessed in erstwhile plague endemic areas of Nilgiris district, Tamil Nadu following standard WHO techniques. The studies revealed the development of resistance in rat fleas to DDT--4.0%, Malathion--5.0%, Deltamethrin--0.05% and tolerance to Permethrin--0.75% in all the four blocks of Nilgiris hill district. Development of resistance may be due to the extensive use of insecticides in tea plantations and agricultural sectors where the domestic/peri-domestic rodents find their natural habitats and intermingle with each other.

    2016-11-01

    The water quality study of Salem district, Tamil Nadu has been carried out to assess the water quality for domestic and irrigation purposes. For this purpose, 59 groundwater samples were collected and analyzed for pH, electrical conductivity (EC), total dissolved solids (TDS), major anions (HCO3 -, CO3 -, F-, Cl-, NO2 - + NO3 -, and SO4 2-), major cations (Ca2+ Mg2+, Na+, and K+), alkalinity (ALK), and hardness (HAR). To assess the water quality, the following chemical parameters were calculated based on the analytical results, such as Piper plot, water quality index (WQI), sodium adsorption ratio (SAR), magnesium hazard (MH), Kelly index (KI), and residual sodium carbonate (RSC). Wilcox diagram represents that 23% of the samples are excellent to good, 40% of the samples are good to permissible, 10% of the samples are permissible to doubtful, 24% of the samples are doubtful unsuitable, and only 3% of the samples are unsuitable for irrigation. SAR values shows that 52% of the samples indicate high-to-very high and low-to-medium alkali water. KI values indicate good quality (30%) and not suitable (70%) for irrigation purposes. RSC values indicate that 89% of samples are suitable for irrigation purposes. MH reveals that 17% suitable and 83% samples are not suitable for irrigation purposes and for domestic purposes the excellent (8%), good (48%), and poor (44%). The agricultural waste, fertilizer used, soil leaching, urban runoff, livestock waste, and sewages are the sources of poor water quality. Some samples are not suitable for irrigation purposes due to high salinity, hardness, and magnesium concentration. In general, the groundwater of the Salem district was polluted by agricultural activities, anthropogenic activities, ion exchange, and weathering.

  13. Evaluating influence of active tectonics on spatial distribution pattern of floods along eastern Tamil Nadu, India

    Selvakumar, R.; Ramasamy, SM.

    2014-12-01

    Flooding is a naturally recurrent phenomenon that causes severe damage to lives and property. Predictions on flood-prone zones are made based on intensity-duration of rainfall, carrying capacity of drainage, and natural or man-made obstructions. Particularly, the lower part of the drainage system and its adjacent geomorphic landforms like floodplains and deltaic plains are considered for analysis, but stagnation in parts of basins that are far away from major riverine systems is less unveiled. Similarly, uncharacteristic flooding in the upper and middle parts of drainage, especially in zones of an anomalous drainage pattern, is also least understood. Even though topographic differences are attributed for such anomalous spatial occurrence of floods, its genetic cause has to be identified for effective management practice. Added to structural and lithological variations, tectonic movements too impart micro-scale terrain undulations. Because active tectonic movements are slow-occurring, long-term geological processes, its resultant topographical variations and drainage anomalies are least correlated with floods. The recent floods of Tamil Nadu also exhibit a unique distribution pattern emphasizing the role of tectonics over it. Hence a detailed geoinformatics-based analysis was carried out to envisage the relationship between spatial distribution of flood and active tectonic elements such as regional arches and deeps, block faults, and graben and drainage anomalies such as deflected drainage, compressed meander, and eyed drainages. The analysis reveals that micro-scale topographic highs and lows imparted by active tectonic movements and its further induced drainage anomalies have substantially controlled the distribution pattern of flood.

    Aim: To identify the suitable roofing pattern for dairy cattle in North East Zone of Tamil Nadu, India, based on micro climatic conditions. Materials and Methods: Initially, survey was conducted to identify and categorize the major housing patterns existing in the region for further detailed investigation. In total, 30 farmers/farms consisting of five housing types with six replicates were selected. Temperature and temperature humidity index (THI) were recorded using the maximum-minimum thermometer and digital thermo-hygrometers. The study was conducted for 1 year covering four seasons namely South West monsoon (June-August), North East monsoon (September-November), cold season (December-February), and summer season (April-May). The data were statistically analyzed using statistical package SPSS 17. Results: Animal shelters with cement sheets recorded the highest temperature (26.71±1.13°C) and THI (77.23±1.76) at 8.00 am, whereas the lowest temperature (24.83±1.17°C) and THI (74.54±1.72) were recorded in the thatched shed. There was significant difference (p<0.01) in temperature and THI at 8.00 am during South West monsoon and North East monsoon seasons between the housing types. During cold and summer seasons, there was no significant difference (p≥0.05) in the environmental variables among various shelter systems. Conclusion: Thatched housing is found to be the suitable one with respect to the climatic variables, followed by tile roof and metal roof. The cement sheet roofed housing is found to be the most unsuitable one in the region for dairy cattle.

    We analysed the genetic structure of ∼1000 samples representing 27 ethnic groups settled in Tamil Nadu, south India, derived from two linguistic families (Dravidians and Indo–Europeans) representing four religious groups (Hinduism, Islam, Christianity and Jainism) using 11 mtDNA markers. Out of 27 ethnic groups, four are in situ populations (Anglo-Indian, Labbai Muslim, Nadar Christian and south Indian Jain) and two are migrants (Gypsy and north Indian Jain) from north India to Tamil Nadu, and 21 are native ethnic groups. Six of the markers we used were monomorphic (HaeIII663, HpaI3592, AluI5176, AluI7025, AluI13262, 9-bp deletion) and five markers were polymorphic (DdeI10394, AluI10397, HinfI12308, HincII13259 and HaeIII16517). Haplogroup frequencies, genetic affinities and admixture analysis are based on the genotype data of polymorphic markers observed in these populations. Haplogroup frequencies indicate that various ethnic groups entered Tamil Nadu during different time periods. Genetic affinities and admixture estimates revealed that the ethnic groups possessing advanced knowledge of farming cluster in a branch (C), and could be the late arrived settlers as agriculture, was introduced to this region at about 5 to 3 thousand years ago. In situ ethnic groups appear to have arisen at various times as a result of the prevailing dominant socio-cultural forces. Hierarchical Hindu caste system created many ethnic groups in the history of its existence; some of them became isolated for considerable period of time. Over all, among Tamil ethnic groups, in spite of caste systems’ rigidity, built in flexibility in the system in the form of hypergamy and hypogamy had allowed maternal gene flow between them.

    Full Text Available Seasonal population trends of butterflies inhabiting the campus of Department of Atomic Energy (DAE at Kalpakkam were recorded by setting a permanent line transect of 300m and recording all species of butterflies observed within a 5m distance. The survey yielded 2177 individuals of 56 butterfly species, belonging to the families Nymphalidae, Pieridae, Lycaenidae, Papilionidae and Hesperiidae. Nymphalidae were found to be the dominant family during all seasons. Species richness and abundance were highest during the northeast monsoon and winter periods, indicating that in the southern plains of India butterflies prefer cool seasons for breeding and emergence. The taxonomic structure of the butterflies sampled resembles that of the Western Ghats and other regions of India in two ways: (a dominance of nymphalids and (b peak abundance during wet seasons. A detailed study of ecologically important local butterfly fauna and their host plants is in progress, to construct a butterfly garden in Kalpakkam to attract and support butterflies.

    Debt bondage in India is often associated with seasonal migration and extreme poverty. If migration is considered as an integral part of the survival strategies of the poor, the impact of migration on relations of exploitation is still very much debated. Various studies undertaken during the 1990s showed that this debt bondage system, at least in its traditional form, gradually fell into disuse because capitalist farming, in actuality, necessitates the mobility of “free labour” that is not bo...

    Renal replacement therapy (RRT) resources are scarce in India, with wide urban-rural and interstate disparities. The burden of end-stage renal disease is expected to increase further due to increasing prevalence of risk factors like diabetes mellitus. Renal transplantation, the best RRT modality, is increasing in popularity, due to improvements made in public education, the deceased donor transplantation (DDT) programme and the availability of free and affordable transplant services in government hospitals and certain non-governmental philanthropic organizations. There are about 120000 haemodialysis patients and 10000 chronic peritoneal dialysis patients in India, the majority of them waiting for a donor kidney. Shortage of organs, lack of transplant facilities and high cost of transplant in private facilities are major barriers for renal transplantation in India. The DDT rate in India is now 0.34 per million population, among the lowest in the world. Infrastructural development in its infancy and road traffic rules not being strictly implemented by the authorities, have led to road traffic accidents being very common in urban and rural India. Many patients are declared brain dead on arrival and can serve as potential organ donors. The DDT programme in the state of Tamil Nadu has met with considerable success and has brought down the incidence of organ trade. Government hospitals in Tamil Nadu, with a population of 72 million, provide free transplantation facilities for the underprivileged. Public private partnership has played an important role in improving organ procurement rates, with the help of trained transplant coordinators in government hospitals. The DDT programmes in the southern states of India (Tamil Nadu, Kerala, Pondicherry) are advancing rapidly with mutual sharing due to public private partnership providing vital organs to needy patients. Various health insurance programmes rolled out by the governments in the southern states are effective in

    As an emerging class of environmentally persistent organic pollutants, perfluorinated compounds (PFCs), particularly perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS); have been universally found in the environment. Wastewater and untreated effluents are likely the major causes for the accumulation of PFCs in surface water. There are very few reports on the contamination of PFCs in the developing countries, particularly in India. This study reports the quantitative analysis of PFOA and PFOS in Noyyal, Cauvery, and also lakes in and around Chennai, using Ultra-Fast liquid chromatograph. The concentration of PFOA and PFOS ranged from 4 to 93ng/L and 3 to 29ng/L, respectively. The concentration of PFOS was below detectable limit in Cauvery River. A reliable concentration of PFOA was recorded at all sites of River Cauvery (5ng/L). The present study could be useful for the assessment of future monitoring programs of PFOA and PFOS in the surface water.

    Full Text Available The transportation system in Kanyakumari District has met the grim situation over the years due to numerous parameters like increasing population, increasing economic activity, increasing vehicular population, negligence from the administrative officials, unethical practices of the locals, etc.; led it to a pathetic condition, especially on National Highway-47. However, to simplify the situation, the National Highway Authority of India (NHAI, Government of India is taking up the effort for developing the new bypass road to the existing NH-47 by diverting form selected few junctions. Unfortunately, this partial solution for the existing NH-47 will give birth to numerous other physical, socio-economic, and ecological problems. The objectives of this study is to identify the possible causes of the inadequacies in prevailing transportation network of Kanyakumari District and put forward logical, scientific and economical conceptual level solutions for the betterment of road users and people of the district. In order to revamp the present dreadful condition, the authors have worked out some simple remedial measures as a solution by conducting exhaustive observation survey, analytical work, discussions with experts and the locals, etc. It includes assessing the prevailing conditions of transportation system in the district, proposing planning design options for rectifying the short comings of the transportation network of the district, conceptualization of the standard flyover design for the NH-47 and ring roads for selected towns of high importance. Further, the paper concludes with plausible and executable recommendations. It is recommended that, in the light of these findings of opportunities and possibilities, the administrative authorities and officials of Kanyakumari district might look into rejuvenating the road transportation scenario of the district.

    Full Text Available Abstract Background The burden of disease of hearing disorders among adults is high, but a significant part goes undetected. Screening programs in combination with the delivery of hearing aids can alleviate this situation, but the economic attractiveness of such programs is unknown. This study aims to evaluate the population-level costs, effects and cost-effectiveness of alternative delivering hearing aids models in Tamil Nadu, India Methods In an observational study design, we estimated total costs and effects of two active screening programs in the community in combination with the provision of hearing aids at secondary care level, and the costs and effects of the provision of hearing aids at tertiary care level. Screening and hearing aid delivery costs were estimated on the basis of program records and an empirical assessment of health personnel time input. Household costs for seeking and undergoing hearing health care were collected with a questionnaire (see Additional file 2. Health effects were estimated on the basis of compliance with the hearing aid, and associated changes in disability, and were expressed in disability-adjusted life years (DALYs averted. Results Active screening and provision of hearing aids at the secondary care level costs around Rs.7,000 (US$152 per patient, whereas provision of hearing aids at the tertiary care level costs Rs 5,693 (US$122 per patient. The cost per DALY averted was around RS 42,200 (US$900 at secondary care level and Rs 33,900 (US$720 at tertiary care level. The majority of people did consult other providers before being screened in the community. Costs of food and transport ranged between Rs. 2 (US$0,04 and Rs. 39 (US$0,83. Conclusion Active screening and provision of hearing aids at the secondary care level is slightly more costly than passive screening and fitting of hearing aids at the tertiary care level, but seems also able to reach a higher coverage of hearing aids services.

    This study proposes to introduce the remote sensing and geographic information system (GIS) techniques in mapping the groundwater potential zones. Remote sensing and GIS techniques have been used to map the groundwater potential zones in Salem Chalk Hills, Tamil Nadu, India. Charnockites and fissile hornblende biotite gneiss are the major rock types in this region. Dunites and peridodites are the ultramafic rocks which cut across the foliation planes of the gneisses and are highly weathered. It comprises magnesite and chromite deposits which are excavated by five mining companies by adopting bench mining. The thickness of weathered and fracture zone varies from 2.2 to 50 m in gneissic formation and 5.8 to 55 m in charnockite. At the contacts of gneiss and charnockite, the thickness ranges from 9.0 to 90.8 m favoring good groundwater potential. The mine lease area is underlined by fractured and sheared hornblende biotite gneiss where groundwater potential is good. Water catchment tanks in this area of 5 km radius are small to moderate in size and are only seasonal. They remain dry during summer seasons. As perennial water resources are remote, the domestic and agricultural activities in this region depend mainly upon the groundwater resources. The mines are located in gently slope area, and accumulation of water is not observed except in mine pits even during the monsoon period. Therefore, it is essential to map the groundwater potential zones for proper management of the aquifer system. Satellite imageries were also used to extract lineaments, hydrogeomorphic landforms, drainage patterns, and land use, which are the major controlling factors for the occurrence of groundwater. Various thematic layers pertaining to groundwater existence such as geology, geomorphology, land use/land cover, lineament, lineament density, drainage, drainage density, slope, and soil were generated using GIS tools. By integrating all the above thematic layers based on the ranks and

    Full Text Available The monitoring and evaluation of lymphatic filariasis (LF has largely relied on the detection of antigenemia and antibodies in human populations. Molecular xenomonitoring (MX, the detection of parasite DNA/RNA in mosquitoes, may be an effective complementary method, particularly for detecting signals in low-level prevalence areas where Culex is the primary mosquito vector. This paper investigated the application of a household-based sampling method for MX in Tamil Nadu, India.MX surveys were conducted in 2010 in two evaluation units (EUs: 1 a hotspot area, defined as sites with community microfilaria prevalence ≥1%, and 2 a larger area that also encompassed the hotspots. Households were systematically selected using a sampling interval proportional to the number of households in the EU. Mosquito pools were collected and analyzed by real-time polymerase chain reaction (qPCR. Two independent samples were taken in each EU to assess reproducibility of results. Follow-up surveys were conducted in 2012.In 2010, the proportion of positive pools in the hotspot EU was 49.3% compared to 23.4% in the overall EU. In 2012, pool positivity was significantly reduced to 24.3% and 6.5%, respectively (p<0.0001. Pool positivity based on independent samples taken from each EU in 2010 and 2012 were not significantly different except for the hotspot EU in 2012 (p = 0.009. The estimated prevalence of infection in mosquitoes, measured by PoolScreen, declined from 2.2-2.7% in 2010 to 0.6-1.2% in 2012 in the hotspot area and from 0.9-1.1% to 0.2-0.3% in the larger area.The household-based sampling strategy for MX led to mostly reproducible results and supported the observed LF infection trends found in humans. MX has the potential to be a cost-effective, non-invasive monitoring and evaluation tool with sensitive detection of infection signals in low prevalence settings. Further investigation and application of this sampling strategy for MX are recommended to support

    The present hydrogeochemical study was confined to the Thoothukudi District in Tamilnadu, India. A total of 100 representative water samples were collected during pre-monsoon and post-monsoon and analyzed for the major cations (sodium, calcium, magnesium and potassium) and anions (chloride, sulfate, bicarbonate, fluoride and nitrate) along with various physical and chemical parameters (pH, total dissolved salts and electrical conductivity). Water quality index rating was calculated to quantify the overall water quality for human consumption. The PRM samples exhibit poor quality in greater percentage when compared with POM due to dilution of ions and agricultural impact. The overlay of WQI with chloride and EC corresponds to the same locations indicating the poor quality of groundwater in the study area. Sodium (Na %), sodium absorption ratio (SAR), residual sodium carbonate (RSC), residual sodium bicarbonate, permeability index (PI), magnesium hazards (MH), Kelly's ratio (KR), potential salinity (PS) and Puri's salt index (PSI) and domestic quality parameters such as total hardness (TH), temporary, permanent hardness and corrosivity ratio (CR) were calculated. The majority of the samples were not suitable for drinking, irrigation and domestic purposes in the study area. In this study, the analysis of salinization/freshening processes was carried out through binary diagrams such as of mole ratios of {SO}_{ 4}^{ 2- } /Cl- and Cl-/EC that clearly classify the sources of seawater intrusion and saltpan contamination. Spatial diagram BEX was used to find whether the aquifer was in the salinization region or in the freshening encroachment region.

    Full Text Available Ambur, a town located on the banks of Palar River, is considered one of the most polluted areas in India and occupied by hundreds of tanneries and leather product units. The present study was designed to evaluate the toxic effect of discharged tannery effluent (TE on model agricultural crops, ecofriendly microorganisms, and human blood cells. The phytotoxic effects of TE tested on Allium cepa and Lemna minor revealed inhibition of root growth and significant reduction in number of fronds, protein, and chlorophyll content. Moreover, TE induced chlorosis and tissue necrosis in Nostoc muscorum at low concentration (10%. TE has also negative impact on ecofriendly microorganisms, Bacillus thuringiensis, Rhizobium etli, and Aspergillus terreus which play an important role in the nutrition of plant growth. The genotoxicity of TE was investigated in human leukocytes which showed interference with normal mitotic division with subsequent cell lysis. It also intervened with the normal replication process and induced micronucleus formation in the healthy leukocyte. 5% concentration of TE has been revealed to be toxic to erythrocytes. From this study TE found in the Palar River of Ambur has adverse effects on all the three levels of organisms in ecosystem even at lower concentrations.

    One of the highly polluted areas in India located at Ranipet occupies around 200 tanneries and other small scale chemical industries. Partially treated industrial effluents combined with sewage and other wastes discharged on the surface cause severe groundwater pollution in the industrial belt. This poses a problem of supply of safe drinking water in the rural parts of the country. A study was carried out to assess the groundwater pollution and identify major variables affecting the groundwater quality in Ranipet industrial area. Twenty five wells were monitored during pre- and post-monsoon in 2008 and analyzed for the major physico-chemical variables. The water quality variables such as total dissolved solids (TDS), Iron (Fe2+), Hexavalent Chromium (Cr6+), at most of the sampling locations exceeded the ISI and WHO guideline levels for drinking water. Multivariate statistical techniques such as factor analysis were applied to identify the major factors (variables) corresponding to the different source of variation in groundwater quality. The water quality of groundwater is influenced by both anthropogenic and chemical weathering. The most serious pollution threat to groundwater is from TDS, Cr6+ and Fe2+, which are associated with sewage and pollution of tannery waste. The study reveals that the groundwater quality changed due to anthropogenic and natural influences such as agricultural, natural weathering process.

    Basic chemicals and their related products like petrochemicals, fertilisers, paints, varnishes, glass, perfumes, toiletries, pharmaceuticals, etc. form a very significant part of the Indian economy and account for about 3% of India's GDP. Among the most diversified industrial sectors, it covers an array of more than 70,000 commercial products. The chemicals sector accounts for about 14% in overall index of industrial production, 11% of total exports and about 7.2% of total imports. The total Foreign Direct Investment in Chemicals (excluding fertilizers) was US 7252 million from April 2011 to March 2012. For inclusive growth and sustainable development most of the Chemical manufacturers should adopt the Cluster Development Approach. The objective is to Study the Occupational Hazards in Cashew Nut Shell Liquid (CNSL) Oil Processing Industries in Panruti Block of Cuddalore District. The methodology adopted is collection of primary processing data during November 2012 from 14 CNSL Processing Industries in Panruti Block of Cuddalore District. Majority of Industries has not processed the CNSL oil as per standards and there is much scope for occupational hazards. In two processes the CNSL oil is let out in the tank constructed equal to ground height where there is possibility of workers getting trapped inside the high temperature CNSL oil. The electric motor is also placed in the ground so that there is possibility of current passing in the ground which leads to occupational hazards for the workers. To conclude, Cashew Shell Oil Processing Industries in Panruti Block of Cuddalore District needs is re-engineering in design and operation starting from Cashew Shell storage, extraction of shell oil from expeller, processing and packaging of CNSL in barrels for better safety from occupational hazards and Cyclones. Moreover for sustainable development, they should adopt cluster development approach, so that infrastructure interrelationships, technology interrelationships

    Full Text Available Background: Tropical rat mite (Ornithonyssus bacoti is reported from many parts of the world and is considered important in transmitting rickettsial pathogens. There have been scanty reports on prevalence of this parasite from India. Following a recent report of O. bacoti infestation in a laboratory mice colony from Nilgiris, Tamil Nadu, In­dia, attempts were made to detect the parasite in its natural reservoir, ie the domestic and peridomestic rats (Rattus rattus.Methods: The National Centre for Disease Control, Coonoor is involved in screening plague in domestic and peridomestic rats in Nilgiris and erstwhile plague endemic areas of Southern India. The parasite samples were identi­fied based on the morphological characteristics attributable to O. bacoti and as per description of published literature.Results: Seven mite samples identified as O. bacoti based on morphological characteristics were isolated inci­dentally from domestic and peridomestic rodents in and around the hilly districts of Nilgiris, Southern India, during the routine plague surveillance programme. The identification was based on the morphological characteristics at­tributable to O. bacoti observed under a low power microscope.Conclusion: In India, this is probably the first record of isolation of O. bacoti from domestic and peridomestic ro­dents. Prevalence of such parasite in domestic and peridomestic rats necessitates further investigation on monitoring and surveillance of rickettsial diseases in the locality, as these parasites are considered to be potential vector of transmitting rickettsial pathogens

    Two Neoproterozoic carbonatite suites of spatially related carbonatites and associated silicate alkaline rocks from Sevattur and Samalpatti, south India, have been investigated in terms of petrography, chemistry and radiogenic-stable isotopic compositions in order to provide further constraints on their genesis. The cumulative evidence indicates that the Sevattur suite is derived from an enriched mantle source without significant post-emplacement modifications through crustal contamination and hydrothermal overprint. The stable (C, O) isotopic compositions confirm mantle origin of Sevattur carbonatites with only a modest difference to Paleoproterozoic Hogenakal carbonatite, emplaced in the same tectonic setting. On the contrary, multiple processes have shaped the petrography, chemistry and isotopic systematics of the Samalpatti suite. These include pre-emplacement interaction with the ambient crustal materials with more pronounced signatures of such a process in silicocarbonatites. Calc-silicate marbles present in the Samalpatti area could represent a possible evolved end member due to the inability of common silicate rocks (pyroxenites, granites, diorites) to comply with radiogenic isotopic constraints. In addition, Samalpatti carbonatites show a range of C-O isotopic compositions, and δ13CV-PDB values between + 1.8 and + 4.1‰ found for a sub-suite of Samalpatti carbonatites belong to the highest values ever reported for magmatic carbonates. These heavy C-O isotopic signatures in Samalpatti carbonatites could be indicative of massive hydrothermal interaction with carbonated fluids. Unusual high-Cr silicocarbonatites, discovered at Samalpatti, seek their origin in the reaction of pyroxenites with enriched mantle-derived alkali-CO2-rich melts, as also evidenced by mantle-like O isotopic compositions. Field and petrographic observations as well as isotopic constraints must, however, be combined with the complex chemistry of incompatible trace elements as indicated

    Sophisticated geochemical models have been used to describe and predict the chemical behaviour of complex natural waters and also to protect the groundwater resources from future contamination. One such model is used to study the hydrogeochemical complexity in a mine area. Extraction of groundwater from the coastal aquifer has been in progress for decades to mine lignite in Neyveli. This extraction has developed a cone of depression around the mine site. This cone of depression is well established by the geochemical nature of groundwater in the region. 42 groundwater samples were collected in a definite pattern and they were analysed for major cations, anions and trace elements. The saturation index (SI) of the groundwater for carbonate, sulphate and silica minerals was studied and it has been correlated with the recharge and the discharge regions. The SI of alumino silicates has been used to decipher the stage of weathering. The SI{sub Gibbsite} - SI{sub K-feldspar} has been spatially distributed and the regions of discharge and recharge were identified. Then two flow paths A1 and A2 were identified and inverse modelling using PHREEQC were carried out to delineate the geochemical process that has taken place from recharge to discharge. The initial and final solutions in both the flow paths were correlated with the thermodynamic silicate stability diagrams of groundwater and it was found that the state of thermodynamic stability of the end solutions along the flow path were approaching similar states of equilibrium at the discharge.

    Full Text Available Groundwater quality in Chennai city along the Cooum river, during the premonsoon (June–July and postmonsoon (Dec–Jan for three years, from 2009 to 2011, was analyzed. Groundwater samples were collected from 20 bore wells on either side of the river. The analysis focused on the determination of seven specific water quality parameters, namely, pH, EC, TDS, BOD, COD, Na and Pb, using standard procedures. The statistical analysis, like the mean and standard deviation, coefficient of variance, and correlation, and multilinear regression analysis of the obtained data were carried out. The analysis of the collected samples reveals that the stated water quality parameters have not complied with the WHO standards, and the water is not fit for drinking and domestic purposes. The correlation and multilinear regression analyses suggest that the conductivity has a significant correlation with the other six considered water quality parameters.

    Storm and tsunami deposits have been identified and described from many siliciclastic coastlines globally. However, as storm and tsunami deposits are both the result of inundation by ocean waves, they can have similar sedimentological and geomorphological signatures. To demarcate storm and tsunami deposits in the geological record, a number of criteria have been proposed to distinguish the two types of deposits. However, these criteria have been assembled from storm and tsunami deposits from coastlines of markedly different onshore and offshore geomorphologies, sedimentary characteristics and sediment sources. Thus, a primary goal for coastal hazard scientists is to define a suite of characteristics that can be used to discern storm from tsunami deposits. This can only be accomplished by identifying recent, known tsunami and storm deposits from the same coastline to directly compare the sedimentary characteristics deposited by these types of events. Here we compare the sedimentology, microfauna and sedimentary structures of two recent events, the 26th December 2004 Indian Ocean Tsunami and the 31st December 2011 Cyclone Thane, from three sites along the Tamil Nadu coastline, south-east India and categorise the similarities and differences between the two deposits. Three sites were investigated, two (SB-1 and SB-2) at Silver Beach, Cuddalore and a third (Pit DPM-3a) at the now blocked Pennai River Mouth north of Cuddalore. At all sites the sedimentary deposits of Cyclone Thane overlie aeolian sands which in turn overly the 2004 Indian Ocean Tsunami deposits. In SB-1 the tsunami deposits have been partially reworked by mangroves that fringed the blocked river. The tsunami deposit found in pit SB-2 overlays a marine intertidal - beach sequence. Pit DPM-3a contains the upper part of the2004 tsunami. In each pit, heavy mineral-rich layers characterise the tsunami and the cyclone deposit, whereas the intervening aeolian sands have only a minor heavy mineral content. Also

Materials and Methods: A total of 1793 records (946 White Giant and 847 Soviet Chinchilla for weight at mating (WM, weight at kindling (WK, gestation length (GL, litter size at birth (LSB and litter size at weaning (LSW, litter weight at birth (LWB, and litter weight at weaning (LWW were collected in the period between 2000 and 2009 and the data was analyzed using general linear model option of SAS 9.2. Results: The overall mean GL, WM, WK, LSB, LSW, LWB, and LWW were 31.68±0.04 days, 3.65±0.01 kg, 3.84±0.01 kg, 6.91±0.08, 5.49±0.09, 387.62±4.07 g, and 4.66±0.07 kg, respectively. The breed has significantly influenced GL, WK, LSW, LWB, and LWW. The LSB, LSW, LWB, and LWW were 7.05±0.11, 5.76±0.13, 399.55±5.88 g, and 4.87±0.10 kg, respectively in White Giant and corresponding values for Soviet Chinchilla were 6.78±0.11, 5.22±0.12, 375.91±5.64 g, and 4.46±0.09 kg, respectively. The year of kindling had significantly affected all the reproductive traits under study and is varying over different years. The parity significantly influenced the WM, WK, and LWW. The LWW increased from first (4.16±0.21 kg to second parity (4.86±0.19 kg and remained in the same range from third parity onward. WM was significantly higher in spring season (3.72±0.02 than the animals in rainy (3.59±0.02 and winter season (3.65±0.02. Better reproductive performance in terms of higher LSB, LSW, LWB, and LWW as observed in the present study might be due to conducive environmental conditions prevailing

    The results of the fourth cycle of the Program for International Student Assessment (PISA) revealed that an unacceptably large number of adolescent students in two states in India-Himachal Pradesh and Tamil Nadu-have failed to acquire basic skills in reading, mathematics, and science (Walker, 2011). Drawing on data from the PISA 2009 database and employing multivariate left-censored to bit regression as a data analytic strategy, the present study, therefore, examined whether or not the learning strategies-memorization, elaboration, and control strategies-of adolescent students in Himachal Pradesh (N = 1,616; Mean age = 15.81 years) and Tamil Nadu (N = 3,210; Mean age = 15.64 years) were linked to their performance on the PISA 2009 reading, mathematics, and science assessments. Tobit regression analyses, after accounting for student demographic characteristics, revealed that the self-reported use of control strategies was significantly positively associated with reading, mathematical, and scientific literacy of adolescents in Himachal Pradesh and Tamil Nadu. While the self-reported use of elaboration strategies was not significantly associated with reading literacy among adolescents in Himachal Pradesh and Tamil Nadu, it was significantly positively associated with mathematical literacy among adolescents in Himachal Pradesh and Tamil Nadu. Moreover, the self-reported use of elaboration strategies was significantly and positively linked to scientific literacy among adolescents in Himachal Pradesh alone. The self-reported use of memorization strategies was significantly negatively associated with reading, mathematical, and scientific literacy in Tamil Nadu, while it was significantly negatively associated with mathematical and scientific literacy alone in Himachal Pradesh. Implications of these findings are discussed.

    The burden of cardiometabolic diseases such as dyslipidemia, hyperglycemia, hypertension, visceral obesity and atherosclerotic cardiovascular diseases and the use of traditional medicine for the management of such diseases are high in India; hence there is a need to document and analyze such therapies. This study documented and analyzed the medicinal plants prescribed for cardiometabolic diseases by the non-institutionally trained siddha practitioners of Tiruvallur district of Tamil Nadu, India. The field survey was conducted between December 2014 to November 2015. Successive free listing assisted with field-walks was used to interview the informants. After assessing the sampling sufficiency using rarefaction curve analysis, indices such as Informant Consensus Factor (Fic) and Index of Agreement on Remedies (IAR) were calculated for the data. The indicators of informant's medicinal plant knowledge such as Shannon's index, equitability index, etc., were regressed with the demographic profile of the informants. For this study 70 non-institutionally trained Siddha medical practitioners were approached; the data from 36 practitioners who were treating cardiometabolic diseases were documented. This study recorded the use of 188 species which were used to prepare 368 formulations to treat illnesses categorized under cardiometabolic diseases. In this, 53.04% claims were singletons. Regression analysis showed that single species dominance was reduced and the diversity of medicinal plants was increased with the increase in the age and experience. Increase in the years of formal education increased the equitability in the uses. The plants such as Nelumbo nucifera Gaertn. (cardiovascular diseases), Allium sativum L. (dyslipidemia), Cuminum cyminum L. (hypertension), Macrotyloma uniflorum Verdc. (obesity) and Azadirachta indica A. Juss. (type 2 diabetes) were the highly cited medicinal plants. This survey has identified the plants most commonly used by Siddha practitioners of

    Full Text Available Background: Wormian bones, also known as intra sutural bones are extra bone pieces that occur within a suture in the cranium. These are irregular isolated bones which appear in addition to the usual centers of ossification of the cranium and, although unusual, are not rare. The number of sutural bones varies considerably because different individuals and different population have different numbers of sutural bones. They occur mostly along the sutures and meeting point of the cranial sutures. They occur most frequently in the course of the lambdoid suture. They are also occasionally seen within the sagittal and coronal sutures. Materials and Methods: In this present study we analyzed the occurrence of sutural bones among 50 male and female skulls in Tamil Nadu region and we compared the results along with the studies of Indian skulls. Result and Conclusion: Based on the study we concluded that sutural bones are more among male skulls than in females among the skulls of Tamil Nadu and this is exactly the opposite of the results given in Indian population.

    We aimed to determine perceived stress levels among adults aged >20 years with type 2 diabetes mellitus (DM) in a tertiary care diabetes center, Chennai, Tamil Nadu, India, assess their association with sociodemographic and clinical characteristics and assess the possible risk factors for stress and coping strategies. A mixed-methods (triangulation design) study with quantitative methodology (survey) and qualitative methodology (interviews) was carried out. Stress levels were assessed among type 2 DM patients attending a diabetes clinic using a 5-point perceived stress scale-10. One-on-one interviews were carried out with 376 participants with DM having high/very high stress levels to understand the reasons for perceived stress and explore their coping mechanisms. The prevalence of high/very high stress was 35% among DM patients. Age 30-40 years, working in professional jobs, and lack of physical activity were factors significantly associated with stress. The perceived major stress inducers were related to family, work, financial issues, and the disease itself. This study showed high levels of stress in more than one-third of DM patients. Potential solutions include regular, formal assessment of stress levels in the clinic, providing integrated counseling and psychological care for DM patients, and promoting physical activity.

    Variations in sea water temperature, salinity, light intensity and availability of nutrients strongly influence the phytoplankton distribution that forms an important part of the coastal food chain. In this paper, we present the results of the physico-chemical parameters and nutrient concentrations in seawaters sampled during the 2009 South West (SW) and post North East (NE) monsoon periods along the continental shelf from Chennai to Nagapattinam, east coast, Tamil Nadu. This study was conducted to assess the status of the coastal biogeochemical environment and for this purpose, seawater samples were collected from the sea surface and also at varying depths (surface to 150 m depth) at six different locations. The nutrient analyses and the CTD data reveal a distinct variation with water depth along the continental slope and also the physico-chemical properties of seawater are not homogenous. The observed values of nutrients for the post NE monsoon period are low compared to the SW monsoon period. Contour plots indicate seasonal and spatial variations in physico-chemical parameters along the continental shelf of the east coast of India. The data suggests that during the 2009 SW monsoon period, a significant increase of freshwater input into the Bay of Bengal could have elevated nutrient concentration compared to that observed during the post 2009 NE monsoon.

    Full Text Available The renewable energy potential of coastal areas of Tamil Nadu, India ranks along with the utmost in the world. This study proposes optimization and cost of energy of different hybrid renewable energy system to power a health clinic in that building. The National Renewable Energy Laboratory (NREL optimization computer model for distributed power, “HOMER,” is used to estimate the optimization and its cost of energy. The implementation of RE systems to supply Rural Health Clinics will contribute to reduce both electricity generation cost and to reduce the consumption of fuel while improving health care and quality of life in these isolated coastal regions. We conclude that using the PV+Wind+Diesel+Battery system for these types of applications in justified on technical and economic grounds. The experimental results show that the least cost of energy at Rs 5.00/KWh, is obtained from above said system and also experiment result shows that the COE decreases with 0% of interest. It is noted, that the PV+Wind+Diesel+Battery hybrid system shows the lowest COE and high amount of Renewable energy.

    India is a signatory to World Health Assembly resolution for elimination of lymphatic filariasis (LF) and National Health Policy has set the goal of LF elimination by 2015. Annual mass drug administration (MDA) is ongoing in endemic districts since 1996-97. Compliance rate is a crucial factor in achieving elimination and was assessed in three districts of Tamil Nadu for 10th and 11th treatment rounds (TRs). An in-depth study assessed the impact of social mobilization by drug distributors (DDs) in two areas from each of the three districts. Overall coverage and compliance for assessed TRs were 76.3 and 67.7% which is below the optimum level to achieve LF elimination. Modifiable determinants continue to be the reason for non-consumption even in the 11th TR and 20.8% were systematic non-compliers. In 76.4% of the cases, DDs failed to adhere to three mandatory visits as per the guidelines. Number of visits by DDs in relation to low and high MDA coverage areas showed a significant relationship (P ≤ 0.000). MDA is limited to drug distribution alone and efforts by DDs in preparing the community were inadequate. Probable means to meet the challenges in preparation of the community is discussed.

    Full Text Available Background: Mental health problems like depression, cognitive impairment, anxiety, sleep disorders, and so on, arising out of senility, neurosis, and living conditions are common in the geriatric population. Aims: To study the psychiatric morbidity among the rural elderly. Settings and Design: A community-based, cross-sectional study. Materials and Methods: A study was conducted on 800 rural elderly subjects, aged 60 years and more, living in ten randomly selected villages, served by the Rural Health Training Center (RHTC, Valadi, in Tamilnadu state, India. Cognitive functioning was assessed by the Mini Mental Status Examination (MMSE, and the depression by the Geriatric Depression Scale - Shorter version. Statistical Analysis: The data was analyzed with SPSS 16 version statistical software using proportions, and the chi-square. Results: A majority of the subjects were widows / widowers, illiterates, living with family, and showing economic dependency. The prevalence of cognitive impairment was 43.25%, with a mean MMSE score of 23.32±4.4, and the depression was 47.0% and 6.16±3.4. Cognitive impairment, depression, and a disturbed sleep pattern were associated with female sex, age, illiteracy, poverty, loneliness, and the low socioeconomic status of the family. Conclusions: The study showed a definite association between the sociodemographic factors and psychiatric morbidity. Encouraging the Non-governmental Organizations (NGOs working for the elderly, running of separate geriatric clinics, and effective implementation of schemes like old age pension are some of the measures to be taken.

    Full Text Available Mitochondria contains a single deoxyribonucleic acid (DNA polymerase, polymerase gamma (POLG mapped to long arm of chromosome 15 (15q25, responsible for replication and repair of mitochondrial DNA. Exon 1 of the human POLG contains CAG trinucleotide repeat, which codes for polyglutamate. Ten copies of CAG repeat were found to be uniformly high (0.88 in different ethnic groups and considered as the common allele, whereas the mutant alleles (not -10/not -10 CAG repeats were found to be associated with oligospermia/oligoasthenospermia in male infertility. Recent data suggested the implication of POLG CAG repeat expansion in infertility, but are debated. The aim of our study was to explore whether the not -10/not -10 variant is associated with spermato g enic failure. As few study on Indian population have been conducted so far to support this view, we investigated the distribution of the POLG CAG repeats in 61 infertile men and 60 normozoospermic control Indian men of Tamil Nadu, from the same ethnic background. This analysis interestingly revealed that the homozygous wild type genotype (10/-10 was common in infertile men (77% - 47/61 and in normozoospermic control men (71.7% - 43/60. Our study failed to confirm any influence of the POLG gene polymorphism on the efficiency of the spermatogenesis.

    Stigma, isoIation and discrimination are typically associated with diagnosis of leprosy and its disclosure. Health care providers (HCPs) find it challenging to disclose the diagnosis of leprosy to patients and their family members. A qualitative study was done in a rural community near Chennai in Tamil Nadu, from August 2011 to March 2012, covering 155 out of 648 (23.9%) purposively selected leprosy patients from 53 out of 148 panchayats, representing 264 villages in the study area; Out of these 155 patients, 59% were males; 30% were illiterates; 70% were married; 56% were living in nuclear families; half the leprosy patients were either agricultural labourers or skilled workers (50%).Thirty two percent were multibacillary (MB) cases and 68% were pauci bacillary (PB) cases; 77% were old patients and 23% were new patients; 22% had leprosy deformity 12% had disfiguration; 23% had anaesthesia and 3% were with lagophthalmous. Of the 155 patients, 31 (20%) reported that they were not informed about diagnosis of their disease by the concerned HCPs. They were informed to be having a skin disease or a skin patch. Of these 31 patients, 22 (71%) were women; all except one with PB leprosy. Seven patients (23%) had not yet started on treatment 3 patients (10%) were given treatment when they were young and neither, them nor their parents were informed about this disease. Seven (33%) of the married patients who had the disease during their child had or when they were young, were not informed of the diagnosis by the HCPs. Ten respondents (32%) were neither bothered nor concerned about non disclosure of the disease by HCPs. Now, after knowing the diagnosis of the disease 4 females (13%) mentioned that they were having some fear, worry or stigma. As non-disclosure of leprosy by HCPs may adversely affect acceptance and adherence, to treatment by the patients, appropriate communication strategies should be developed and implemented.

    The Government of India had set up the National Rural Health Mission (NRHM) in 2005 in an effort towards providing quality healthcare to the underserved rural areas and also to achieve the Millennium Development Goals (MDGs) by 2015. While the trends in child and maternal mortality show great progress by India since 1990 with steady decline in Maternal Mortality Ratio (MMR) and Infant Mortality Rate (IMR), a comparison of the predicted trend and target of MDGs show that India would fall short by a few points. In contrast, Tamil Nadu has reached its MDGs and is ensuring sustained progress in reducing child and maternal mortality with an effective implementation of the various schemes of NRHM. Tamil Nadu leads the way in ensuring universal health coverage leveraging the expertise and funds of NRHM by providing round the clock services, introducing new and innovative programs to improve outcomes and regular monitoring of the functional operation and outcomes to ensure effective implementation. Adopting the features of the Tamil Nadu model of healthcare system that caters to their particular state and effectively implementing the initiatives of NRHM would help the other states in considerably reducing the child and maternal mortality and also ensure early achievement of MDGs by the nation.

    Mining of nutrients from soil is a major problem in developing countries causing soil degradation and threaten long-term food production. The present study attempts to apply NUTrient MONitoring (NUTMON) model for carrying out nutrient budgeting to assess the stocks and flows of nitrogen (N), phosphorus (P), and potassium (K) in defined geographical unit based on the inputs, viz., mineral fertilizers, manures, atmospheric deposition, and sedimentation, and outputs, viz., harvested crop produces, residues, leaching, denitrification, and erosion losses. The study area covers Coimbatore and Erode Districts, which are potential agricultural areas in western agro-ecological zone of Tamil Nadu, India. The calculated nutrient balances for both the districts at district scale, using NUTMON methodology, were negative for nitrogen (N -3.3 and -10.1 kg ha(-1)) and potassium (K -58.6 and -9.8 kg ha(-1)) and positive for phosphorus (P +14.5 and 20.5 kg ha(-1)). Soil nutrient pool has to adjust the negative balance of N and K; there will be an expected mining of nutrient from the soil reserve. A strategy was attempted for deriving the fertilizer recommendation using Decision Support System for Integrated Fertilizer Recommendation (DSSIFER) to offset the mining in selected farms. The results showed that when DSSIFER recommended fertilizers are applied to crops, the nutrient balance was positive. NUTMON-Toolbox with DSSIFER would serve the purpose on enhancing soil fertility, productivity, and sustainability. The management options to mitigate nutrient mining with an integrated system approach are also discussed.

    The present study was carried out to evaluate the groundwater quality and its suitability for drinking purposes in the urban coastal aquifers of part of south Chennai, Tamil Nadu, India. Twenty-three groundwater samples were collected during March 2012. The minimum and maximum values of pH (6.3-8 on scale), electrical conductivity (620-12,150 μS/cm), total dissolved solids (399.28-7,824.6 mg/l), carbonate (0-30 mg/l), bicarbonate (0.9-58.9 mg/l), chloride (70.9-4,067.89 mg/l), sulphate (17.4-105 mg/l), nitrate (0.4-6.0 mg/l), calcium (30-200 mg/l), magnesium (1.2-164 mg/l), sodium (69-1,490 mg/l) and potassium (8-340 mg/l) were recorded in the coastal aquifers of Chennai city. The groundwater samples show that the majority of the sampling points clustered on the NaCl and mixed CaMgCl facies of the piper trilinear diagram. In the Gibbs diagram, the majority of the sampling points fall under rock water and evaporation dominance field. Fuzzy membership classification suggests that the majority of the samples fall under good water type followed by excellent water and poor water categories. Groundwater quality index showing the majority of the samples falls under excellent to poor category of water. A positive correlation was observed with Cl-, SO4 2-, Ca2+, Na+, K+, EC and TDS. The extracted results of the correlation matrix and geochemical analysis suggest that the dominant ions of groundwater (Na+, Ca2+, K+, Cl- and SO4 2-) were derived from seawater intrusion and gypsum dissolution process. Nitrate concentration is most significantly derived from anthropogenic sources.

    The Topographic maps and Aerial Photographs are used for morphometric analysis of drainage basins and mapping contours with drainage. The stereo pairs of 2.5 m resolution Cartosat 1, Indian satellite 2 and merged data with 5.5 m resolution P6 Resourcesat 1 LISS 4 Indian satellite of 2001 is used to map, rills, gullies, and streams of first order to evaluate part of drainage basin of Cooum and Poondi Reservoir in Thiruvallur taluk of Tamil Nadu state. The Geo Eye latest 2011data is also used with Catrosat 1Stereo data to study present morphology of tiny micro watersheds to study the use of High resolution data for delineation and codification of watersheds. This study area is in an inter fluvial drainage basin of Cooum and Kusasthalai rivers. Kusasthalai river drains in Poondi reservoir which is about 50 km from Chennai. The excess water from Kosasthalai is also diverted through Kesawaram weir to Cooum river which passes through Thiruvallur and Chennai city before it's confluence with Bay of Benegal in the east. As Cooum basin is at higher elevation, water for irrigation is again diverted through chain of tanks to Kusasthalai river basin to drain in Poondi reservoir. Delineation of water sheds in this fluvial basin is difficult by manual survey as man made irrigation channels, natural drainage streams etc., have to be clearly identified.

    Full Text Available The Topographic maps and Aerial Photographs are used for morphometric analysis of drainage basins and mapping contours with drainage. The stereo pairs of 2.5 m resolution Cartosat 1, Indian satellite 2 and merged data with 5.5 m resolution P6 Resourcesat 1 LISS 4 Indian satellite of 2001 is used to map, rills, gullies, and streams of first order to evaluate part of drainage basin of Cooum and Poondi Reservoir in Thiruvallur taluk of Tamil Nadu state. The Geo Eye latest 2011data is also used with Catrosat 1Stereo data to study present morphology of tiny micro watersheds to study the use of High resolution data for delineation and codification of watersheds. This study area is in an inter fluvial drainage basin of Cooum and Kusasthalai rivers. Kusasthalai river drains in Poondi reservoir which is about 50 km from Chennai. The excess water from Kosasthalai is also diverted through Kesawaram weir to Cooum river which passes through Thiruvallur and Chennai city before it's confluence with Bay of Benegal in the east. As Cooum basin is at higher elevation, water for irrigation is again diverted through chain of tanks to Kusasthalai river basin to drain in Poondi reservoir. Delineation of water sheds in this fluvial basin is difficult by manual survey as man made irrigation channels, natural drainage streams etc., have to be clearly identified. The streams of various orders are identified based on Strahler stream order hierarchy of tributaries, slops and contours using large scale satellite data.

    Full Text Available Background: Medicine and engineering still seems to be the most chosen career and the decision in the choice is largely influenced by the parents. Right attitude toward the chosen profession and the perceptions about the existing curriculum are important for any student to be successful in the college as well as in the career. Materials and Methods: A descriptive cross-sectional study was carried out among 466 undergraduate (bachelor of dental surgery students from randomly chosen dental colleges in Tamil Nadu to assess their attitude and perception toward their curriculum and profession. A validated closed ended questionnaire with 18 questions was used in this study. The information obtained were: Reason to opt for the dental course, the most-hated part of the curriculum, adequacy of lecture and clinical hours, number and duration of lecture classes and clinical hours preferred, reason for not liking a particular subject, and the most important factor to be considered to rate a teacher. The proportion of the response was calculated to assess the overall attitude and perceptions of the students. Results: Forty-two percent of the students opted for the dental course because they did not get admission to the medical course. Written assignments (52% were the most hated part of their curriculum. -42% of the students believed that the ideal attendance percentage should be 75%. Knowledge and teaching skills (79% was the most important factor that was considered to rate a teacher. Conclusion: Majority of the students developed passion toward their profession. There was no serious complains about the existing curriculum, but a newer education model that can enhance the problem solving, and critical evaluation skills of the student is warranted.

  3. Monsoon Harvests: Assessing the Impact of Rainwater Harvesting Ponds on Subsistence-Level Agriculture in the Gundar Basin, Tamil Nadu, India

    Lack of consistent water availability for irrigated agriculture is recognized as one of the primary constraints to meeting the UN Millennium Development Goals to alleviate hunger, and in semi-arid landscapes such as those of southern India, which are characterized by high intra-annual variability in rainfall, provision of capabilities for seasonal storage is recognized to be one of the key strategies towards alleviating water scarcity problems and ensuring food security. Although the issue of increased storage can be addressed by centralized infrastructure projects such as large-scale irrigation systems and dams, an alternative is the "soft path" approach, in which existing large-scale projects are complemented by small-scale, decentralized solutions. Such a decentralized approach has been utilized in southern India for thousands of years in the form of village rainwater harvesting tanks or ponds, providing a local and inherently sustainable approach to providing sufficient water for rice cultivation. Over the last century, however, large-scale canal projects and groundwater pumping have replaced rainwater harvesting as the primary source of irrigation water. But with groundwater withdrawals now exceeding recharge in many areas and water tables continuing to drop, many NGOs and government agencies are advocating for a revival of the older rainwater harvesting systems. Questions remain, however, regarding the limits to which rainwater harvesting can provide a solution to decades of water overexploitation. In the present work, we have utilized secondary data sources to analyze the linkages between the tank irrigation systems and the village communities that depend on them within the Gundar Basin of southern Tamil Nadu. Combining socioeconomic data with information regarding climate, land use, groundwater depletion, and tank density, we have developed indicators of sustainability for these systems. Using these indicators, we have attempted to unravel the close

    Background & objectives: Dengue is the most rapidly expanding arboviral disease in India. Aedes aegypti is the primary vector of dengue fever. Chemical insecticides have long been used in the vector control programmes along with other control measures. However, continuous use of insecticides targeting Ae. aegypti may lead to development of insecticide resistance. Though resistance in Ae. aegypti has been reported, the mutation in ace-1 gene associated with temephos resistance is not reported ...

    Over the past few years advancements in family welfare programs have occurred in India. One state in the Indian Union, Tamil Nadu, has had significant success in its family planning strategies. Examined is the fertility trends over a period of years within this area. Focus is on fertility decline, calculated from changing birthrates. Decline was differentiated in terms of crude birth rates. Chosen were standardized birth rates adjusted for age (females 15-49 years old), and standardized birth rates adjusted for both age structure and marital status. Family planning programs in Tamil Nadu were classified according to periods of years - 1956-1971 as the pre-intensive program period, and 1971-1986 as the intensive program period. Methodology included simple correlation and regression with additional computations, and multilinear regression measuring impacts on fertility decline of a small number of various factors. Conclusions drawn showed a swift decline in fertility in Tamil Nadu from 1971-1988, more so than during the period of 1956-1971. Family welfare programs were examined as well as through 4 key variables: infant mortality rates, female employment, female educational attainment, and family planning utilization. All 4 variables have shown a positive influence on fertility decline in Tamil Nadu. Both crude and standardized birth rates, as shown by measuring births averted during 1986, can be effectively used in producing births averted in any particular future time period.

    High grade metamorphism and intense deformation have given a well recognition to the Southern Granulite Terrane (SGT) in India. TTG-Charnockite and basic granulites constitute the dominant lithoassociation of the area. Dunite-peridotite-anorthosite-shonkinite and syenites are the intrusives. TTG-charnockite-basic granulite have undergone F1 (isoclinal recumbent), F2 (NE-SW) and F3 (NW-SE) folds producing several interference pattern. E-W trending Neoarchean and Palaeoproterozoic Salem-Attur Shear Zone exhibits a low angle ductile thrust as well as some foot print of late stage brittle deformation near Gangavalli area of Tamil Nadu. The thrust causes exhumation of basic granulites to upper crust. Thrusting along the decollement has retrograded the granulite into amphibolite rock. Subsequently, deformation pattern of Gangavalli area has distinctly marked by numerous vertical to sub-vertical fractures mostly dominating along 0-15 and 270-300 degree within charnockite hills that creates a maximum stress (σ1) along NNW and minimum stress (σ3) along ENE. However, emplacement of pseudotachylyte vein along N-S dominating fracture indicates a post deformational seismic event. Extensive fractures produce anastomose vein with varying thickness from few millimeters to 10 centimeters on the outcrop. ICP-AES study results an isochemical composition of pseudotachylyte vein that derived from the host charnockitic rock where it occurs. But still some noticeable variation in FeO-MgO and Na2O-CaO are obtained from different parts within the single vein showing heterogeneity melt. Electron probe micro analysis of thin sections reveals the existence of melt immiscibility during its solidification. Under dry melting condition, albitic rich melts are considered to be the most favorable composition for microlites (e.g. sheaf and acicular micro crystal) re-crystallization. Especially, acicular microlites preserved tachylite texture that suggest its formation before the final coagulation

    Women's control over their own bodies and reproduction is a fundamental prerequisite to the achievement of sexual and reproductive health and rights. A woman's ability to terminate an unwanted pregnancy has been seen as the exercise of her reproductive rights. This study reports on interviews with 15 women in rural South India who had a medical abortion. It examines the circumstances under which they chose to have an abortion and their perspectives on medical abortion. Women in this study decided to have an abortion when multiple factors like lack of spousal support for child care or contraception, hostile in-laws, economic hardship, poor health of the woman herself, spousal violence, lack of access to suitable contraceptive methods, and societal norms regarding reproduction and sexuality converged to oppress them. The availability of an easy and affordable method like medical abortion pills helped the women get out of a difficult situation, albeit temporarily. Medical abortion also fulfilled their special needs by ensuring confidentiality, causing least disruption of their domestic schedule, and dispensing with the need for rest or a caregiver. The study concludes that medical abortion can help women in oppressive situations. However, this will not deliver gender equality or women's empowerment; social conditions need to change for that.

    The feasibility of a potential bioindicator based on functional groups of microzooplankton tintinnids for bioassessments of water quality status was studied during southwest monsoon (June to September) along the coastal waters of Kalpakkam, India during 2012-2015. The work highlights the following features (1) tintinnid community composed of 28 species belonging to 11 genera and 9 families, revealed significant differences among the four study sites (2) maximum numerical abundance (2224±90ind. l(-1)) and species diversity (H'=2.66) of tintinnid were recorded towards Bay of Bengal whereas minimum abundance (720±35ind. l(-1)) and diversity (H'=1.74) were encountered in the backwater sites, (3) multivariate analyses [RELATE, Biota-environment (BIOENV) and canonical analysis of principal coordinates (CAP)] reveal that chl a, nitrate and phosphate were the potential causative factors for tintinnid distribution. Based on the results, we suggest that tintinnids may be used as a potential bioindicator of water quality status in marine ecosystem. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The macrobenthic fauna and communities of the Vellar Estuary located at the southeast cost of India (11°30' N, 79°45' E) and the adjacent marine and river habitats are described on the basis of original data (70 samples over 10 transects). The fauna consists of 115 macrobenthic species and 79 species in estuarine habitats. We described 14 types of macrobenthic communities with different compositions of the dominant species. The leading ecological factors of the distribution of the communities are the salinity, depth, and bottom type. The Vellar estuary consists of two longitudinal zones of macrobenthos. The polyhalinic area is populated by the marine species, but it is related not to a salinity decrease but to the protection from waves and silt on the bottom in this area. The polyhalinic communities are most abundant in terms of the biomass and species richness. The mesohalinic area is inhabited by brackish water species and communities with low abundance. The sublittoral estuarine area is dominated by filter-feeders—the bivalves Crassostrea madrasensis, Meretrix casta, Modiolus metcalfei, and Scapharca inaequivalves—and the littoral zone is dominated by the gastropods Cerithidea cingulata, some crabs, and polychaetes. The ecosystem function of the Vellar estuary can be defined as a filter for the fine organic particles transported by the river.

    We use electrical resistivity data arrayed in a 2715 km2 region with 30 locations to identify the saline water intrusion zone in part of Cauvery deltaic region, offshore Eastern India. From this dataset we are able to derive information on groundwater quality, thickness of aquifer zone, structural and stratigraphic conditions relevant to groundwater conditions, and permeability of aquifer systems. A total of 30 vertical electrode soundings (VES) were carried out by Schlumberger electrode arrangement to indicate complete lithology of this region using curve matching techniques. The electrical soundings exhibited that H and HK type curves were suitable for 16 shallow locations, and QH, KQ, K, KH, QQ, and HA curves were fit for other location. Low resistivity values suggested that saline water intrusion occurred in this region. According to final GIS map, most of the region was severely affected by seawater intrusion due to the use of over-exploitation of groundwater.The deteriorated groundwater resources in this coastal region should raise environmental and health concerns.

    Groundwater is the most important natural resource which cannot be optimally used and sustained unless its quality is properly assessed. In the present study, the spatial and temporal variations in physicochemical quality parameters of groundwater of Araniar River Basin, India were analyzed to determine its suitability for drinking purpose through development of drinking water quality index (DWQI) maps of the post- and pre-monsoon periods. The suitability for drinking purpose was evaluated by comparing the physicochemical parameters of groundwater in the study area with drinking water standards prescribed by the World Health Organization (WHO) and Bureau of Indian Standards (BIS). Interpretation of physicochemical data revealed that groundwater in the basin was slightly alkaline. The cations such as sodium (Na(+)) and potassium (K(+)) and anions such as bicarbonate (HCO3 (-)) and chloride (Cl(-)) exceeded the permissible limits of drinking water standards (WHO and BIS) in certain pockets in the northeastern part of the basin during the pre-monsoon period. The higher total dissolved solids (TDS) concentration was observed in the northeastern part of the basin, and the parameters such as calcium (Ca(2+)), magnesium (Mg(2+)), sulfate (SO4 (2-)), nitrate (NO3 (-)), and fluoride (F(-)) were within the limits in both the seasons. The hydrogeochemical evaluation of groundwater of the basin demonstrated with the Piper trilinear diagram indicated that the groundwater samples of the area were of Ca(2+)-Mg(2+)-Cl(-)-SO4 (2-), Ca(2+)-Mg(2+)-HCO3 (-) and Na(+)-K(+)-Cl(-)-SO4 (2-) types during the post-monsoon period and Ca(2+)-Mg(2+)-Cl(-)-SO4 (2-), Na(+)-K(+)-Cl(-)-SO4 (2-) and Ca(2+)-Mg(2+)-HCO3 (-) types during the pre-monsoon period. The DWQI maps for the basin revealed that 90.24 and 73.46% of the basin area possess good quality drinking water during the post- and pre-monsoon seasons, respectively.

    Full Text Available In Tamil Nadu, one of the most populated states in the South of India, the relationship between cinema, television and politics can explain the success of some of its political leaders. Leaders who started their public activity as directors, actors or script writers, activities which they were successfully able to combine with their roles as public servants. The ethnical and religious diversity of this region, along with the unswayable support of their groups of fans, gave birth to the creation of nationalist political parties which do not hesitate to defend their cultural idiosyncrasy as a sign of social identity. The political game in Tamil Nadu highlights the importance that media, and especially cinema, has had since the forties and fifties of the twentieth century in shaping the political scene. This article, with a historical perspective, has as an objective to determine the turning points of this complex relationship between audiovisual and politics, correlation characteristic of Tamil Nadu but also of India as a whole.

    Iron deficiency anemia (IDA) affects 70% of under-5 children in India. The primary prevention strategy is regular iron supplementation. Little is known about what helps families adhere to daily iron supplementation. Our study explored the knowledge, attitudes, and practices of mothers and village health workers (VHWs) involved in a community health program in one hill district of Tamil Nadu. We conducted 30 semistructured interviews and 3 group discussions involving mothers, VHWs, and community stakeholders. Knowledge of IDA was widespread, yet no children were receiving the iron supplementation as recommended. The main determinants to adherence included the perception of its need, the ease of access, and the activity of VHWs. Preventive care requiring daily supplements is challenging. Our study suggests that increasing community awareness of mild anemia, simplifying dosage instructions, and further strengthening the supportive environment for VHWs would help in reducing the prevalence of IDA.

    A previous hospital based study from Delhi revealed a high prevalence of hypothyroidism in pregnant women. Several other studies with small sample size also indicate a rising trend of prevalence of hypothyroidism during pregnancy in India. To assess prevalence of hypothyroidism in pregnant women from various states/cities across India. This was a cross-sectional multicenter study conducted at Allahabad (Uttar Pradesh), Bengaluru (Karnataka), Chennai (Tamil Nadu), Kolkata (West Bengal), Hyderabad (Telangana), Nasik (Maharashtra), Rohtak (Haryana), Pune (Maharashtra), New Delhi (Delhi), Srinagar (Kashmir), and Vizag (Andhra Pradesh) enrolling 2599 pregnant women. Estimation of thyroid stimulating hormone (TSH), free T4, and antithyroid peroxidase (TPO) antibodies was carried out using Roche modular kit using ECLIA technology in a central laboratory. We found in our study population that 13.13% of pregnant women have hypothyroidism (n = 388), using a cutoff TSH level of 4.5 μIU/ml. This prevalence was much higher using the American Thyroid Association criteria. Anti-TPO antibodies were positive in 20.74% of all pregnant women (n = 613), whereas 40% (n = 155) of hypothyroid pregnant women were positive for anti-TPO antibodies. This study concludes that there is a high prevalence of hypothyroidism (13.13%), majority being subclinical in pregnant women during the first trimester from India and universal screening of hypothyroidism may be desirable in our country.

    India with a population of 1.2 billion has a renal transplantation rate of 3.25 per million population. The major cause of chronic kidney disease is hypertension and diabetes. The crude and age-adjusted incidence rates of end-stage renal disease are estimated to be 151 and 232 per million population, respectively, in India. There was a remarkable lack of knowledge in the public about deceased organ donation until a decade ago. However, the role played by the media and nongovernmental organizations in partnership with the government has emphasized and implemented deceased donor transplantation in certain states in India-to mention particularly, the Tamil Nadu model. In the last 2 years, deceased organ donation has reached 1.3 per million population in Tamil Nadu, thereby effectively eliminating commercial transplantation. There is no religious bar for organ donation. A central transplant coordinator appointed by the government oversees legitimate and transparent allocation of deceased organs both in the public and private facilities as per the transplant waiting list. This model also takes care of the poor sections of society by conducting donation and transplantation through government-run public facilities free of cost. In the last 2 years, deceased donor transplantation has been performed through this network procuring organs such as the heart, heart valves, lung, liver, kidneys, cornea, and skin. The infrastructural lack of immunological surveillance-including donor-specific antibody monitoring, human leukocyte antigen typing, and panel reactive antibody except in a few tertiary care centers-prevents allocation according to the immunological status of the recipient. This private-public partnership promoting deceased donor transplantation has effectively eliminated commercialization in transplantation in the state of Tamil Nadu with a population of 72 million which is a model for other regions of South Asia and developing countries.

    Full Text Available The population dynamics of tree species were studied in both deciduous and evergreen forests at Kodayar in the Western Ghats of Tamil Nadu. The mortality of trees was less than the number of new recruits, resulting in a net gain in population density and basal area. The increase in net population density and basal area of tree species could be because of their entry into the adult stage from the already existing sapling and seedling bank. Greater mortality of juveniles than that of adults could be due to intense competition for limited available resources at the juvenile stage. The present study concludes that to a larger extent, the forest ecosystems here are at building phase. Long-term studies are needed to understand the regeneration niche.

    Full Text Available The Pachamalai Hills are a part of the Eastern Ghats and are situated in the central region of Tamil Nadu. The vegetated area is distributed into 35 reserved forests of Pachamalai Hills. The plant Decalepis hamiltonii Wight & Arn. is one of the threatened plant found in the study area. This indicates that the Pachamalai Hills can harbour good vegetation which are the vestiges of a luxuriant vegetation cover of the past era, hence, need to be protected. The hills are most significant socio-culturally because of the diversified forest patches found there. These hills have been studied earlier mainly for floristic analysis. Before this, D. hamiltonii has not been collected from Pachamalai.

    This study investigates the pollution vulnerability of bore water in the coastal region of Tirunelveli and Thoothukudi in the state of Tamilnadu, India. There are no industries in the Tirunelveli Coastal area whereas there are many industries in SIPCOT (State Industries Promotion Corporation of Tamilnadu) Thoothukudi, and coastal area of Thoothukudi. Bore water from the SIPCOT, coastal area of Thoothukudi and Tirunelveli were collected periodically from July 2006 to May 2008 for this study. These samples were tested and analyzed to find the concentrations of sodium, magnesium, aluminium, potassium, calcium, copper, cadmium, mercury and lead. The toxic cadmium concentration was found in the range of 0.00-0.22 mg Kg⁻¹ at SIPCOT 2 in November 2007, mercury 0.00-0.024 mg Kg⁻¹ and lead 0.00-0.02 mg Kg⁻¹ in SIPCOT 2 in January 2008. The level of contamination is higher than the WHO limits of drinking water standards; but copper and aluminium content are within the limit. On the other hand, the samples taken from bores in Tirunelveli coastal area are non-polluted, and the analysis shows that all the metals are within the limits of WHO standard.

    Full Text Available Clients of female sex workers (FSWs possess a high potential of transmitting HIV and other sexually transmitted infections from high risk FSWs to the general population. Promotion of safer sex practices among the clients is essential to limit the spread of HIV/AIDS epidemic. The aim of this study is to estimate the prevalence of consistent condom use (CCU among clients of FSWs and to assess the factors associated with CCU in Tamil Nadu. 146 male respondents were recruited from the hotspots who reportedly had sex with FSWs in exchange for cash at least once in the past one month. Data were analyzed using bivariate and multivariate methods. Overall, 48.6 and 0.8 percent clients consistently used condoms in the past 12 months with FSWs and regular partners, respectively. Logistic regression showed that factors such as education, peers’ use of condoms, and alcohol consumption significantly influenced clients’ CCU with FSWs. Strategies for safe sex-behaviour are needed among clients of FSWs in order to limit the spread of HIV/AIDS epidemic in the general population. The role of peer-educators in experience sharing and awareness generation must also be emphasized.

    Fuel energy demand is of great concern in recent times due to the depletion of fossil fuel resources. Biomass serves as widely available primary renewable energy source. Hence, a study was performed to assess the above-ground biomass yielding capability of fuel wood tree Prosopis juliflora in three varied ecosystems viz., coastal, fallow land and riparian ecosystems in southern districts of Tamil Nadu. The results showed that the biomass production potential and above-ground net primary productivity of P. juliflora depend on the age of the tree stands and the nature of ecosystem. A higher biomass yield was observed for P. juliflora trees with 5 to 10 years old when compared to less than 5 years of their age. Among the three ecosystems, the maximum biomass production was recorded in riparian ecosystem. The stands with less than 5-year-old P. juliflora trees gave 1.40 t/ha, and 5- to 10-year-old tree stands produced 27.69 t/ha in riparian ecosystem. Above-ground net primary productivity of both the age groups was high in fallow land ecosystem. In riparian ecosystem, the wood showed high density and low sulphur content than the other two ecosystems. Hence, P. juliflora biomass can serve as an environmentally and economically feasible fuel as well as their utilization proffers an effective means to control its invasiveness.

  8. Influence of behavioral biases on the assessment of multi-hazard risks and the implementation of multi-hazard risks mitigation measures: case study of multi-hazard cyclone shelters in Tamil Nadu, India

    2013-04-01

    In December 2004, a multiple hazards event devastated the Tamil Nadu province of India. The Sumatra -Andaman earthquake with a magnitude of Mw=9.1-9.3 caused the Indian Ocean tsunami with wave heights up to 30 m, and flooding that reached up to two kilometers inland in some locations. More than 7,790 persons were killed in the province of Tamil Nadu, with 206 in its capital Chennai. The time lag between the earthquake and the tsunami's arrival in India was over an hour, therefore, if a suitable early warning system existed, a proper means of communicating the warning and shelters existing for people would exist, than while this would not have prevented the destruction of infrastructure, several thousands of human lives would have been saved. India has over forty years of experience in the construction of cyclone shelters. With additional efforts and investment, these shelters could be adapted to other types of hazards such as tsunamis and flooding, as well as the construction of new multi-hazard cyclone shelters (MPCS). It would therefore be possible to mitigate one hazard such as cyclones by the construction of a network of shelters while at the same time adapting these shelters to also deal with, for example, tsunamis, with some additional investment. In this historical case, the failure to consider multiple hazards caused significant human losses. The current paper investigates the patterns of the national decision-making process with regards to multiple hazards mitigation measures and how the presence of behavioral and cognitive biases influenced the perceptions of the probabilities of multiple hazards and the choices made for their mitigation by the national decision-makers. Our methodology was based on the analysis of existing reports from national and international organizations as well as available scientific literature on behavioral economics and natural hazards. The results identified several biases in the national decision-making process when the

    Full Text Available Work life balance plays an important role now a day. Employees want it, managers need it, and organization cannot afford to ignore it! Managers need to take work-life balance seriously particularly in garment units. The more overworked and overloaded, the higher the demands or the expectations on the department or the work unit, the more the managers have to rely on their employees to produce at the highest possible level of efficiency, effectiveness, and quality. If managers are out of balance or stressed or sick then they will be less committed to the outcomes, they will be less committed to the organization, they will be less committed to the client, the product or goods or service that they are producing. This research paper examined the work life balance amongst managers of garment units in Tamil nadu state. The methodology adopted for the study was descriptive research design. Data were collected from 480 managers through questionnaire method around Tamilnadu state, India. In the present study, stastical tools such as percentage analysis, mean value, chi-square, ANOVA, and correlation analysis were used for the analysis. The results indicated that the work life balance of managers are not completely successful due to their present working hours, working environment and increase in products prices, work load, responsibilities in work and  decrease of job security due to recession.

    Full Text Available Background: Hypertensive disorder is the second most common medical disorder seen during pregnancy. They along with hemorrhage and infection, contribute greatly to maternal morbidity and mortality. Most deaths in PIH occur due to its complications and not due to hypertension per sec. Thus, maternal mortality and these complications are preventable. The objective of the present study was undertaken to study pattern of feto-maternal outcome and complications in cases of pregnancy induced hypertension with a view to identify them at the earliest. Methods: The current survey was planned and executed by the department of obstetrics and gynaecology of a tertiary care teaching institution of Tamil Nadu during November 2013 to October 2015 using a pre-designed questionnaire among 245 study participants. The study population consisted of pregnant women seeking care for PIH. Results: 59.6% cases of mild PIH, 22% cases of moderate PIH and 18.4% cases of severe PIH. Regarding maternal complications in PIH, in severe cases of PIH there were CCU admissions in 8.9% cases, imminent eclampsia in 31.1% cases and abruptio placentae, CVA, acute renal failure in 2.2% cases. DIC and maternal mortality was seen in 4.4% cases. Regarding foetal complications in PIH, in severe cases of PIH there was birth asphyxia in 31.1% cases. Intra uterine growth retardation was seen in 24.4% cases. The most common reason for NICU admission was preterm with low birth weight. Conclusions: Emphasis should be on early registration and regular ANC visits. Early detection and prompt intervention of complications is vital for ensure a healthy outcome to both mother and baby.

    Oriented samples of sediments from Ariyalur Group, Cauvery Basin, south India, were studied for low field anisotropy of magnetic susceptibility (AMS) measurements to unravel the magnetic fabrics and paleocurrent directions. The results of AMS parameters of the sediments indicate primary depositional fabrics for Sillakkudi, Ottakovil and Kallamedu sandstone formations and secondary fabric for Kallankurichchi limestone formation. The obtained low degree of anisotropy (), oblate shape AMS ellipsoid and distribution of maximum (1) and minimum (3) susceptibility axes on equal area projection confirm the primary sedimentary fabric for Sillakkudi, Ottakovil and Kallamedu Formations. In the case of ferruginous, lower arenaceous, Gryphaea limestone and upper arenaceous limestone beds of Kallankurichchi Formation have recorded more than one fabric. The observed AMS parameters like shape factor () (prolate to oblate), value and random distribution of minimum (3) and maximum (1) susceptibility axes are supported for secondary fabrics in Kallankurichchi Formation as a result of post-depositional processes. Based on petrographic studies, it can be established that 1 AMS axis of biotite mineral could represent the flow direction. The established paleocurrent direction for Sillakkudi is NW–SE direction while Ottakovil and Kallamedu Formations recorded NE–SW direction. Overall the paleoflow directions observed for Ariyalur Group is NE–SW to NW–SE.

    Eugenia singampattiana is an endangered medicinal plant used by the Kani tribals of South India. The plant had been studied for its antioxidant, antitumor, antihyperlipidemic, and antidiabetic activity. But its primary and secondary metabolites profile and its antiviral properties were unknown, and so this study sought to identify this aspect in Eugenia singampattiana plant through different extraction methods along with their activities against porcine reproductive and respiratory syndrome virus (PRRSV). The GC-MS analysis revealed that 11 primary metabolites showed significant variations among the extracts. Except for fructose all other metabolites were high with water extract. Among 12 secondary metabolites showing variations, the levels of 4-hydroxy benzoic acid, caffeic acid, rutin, ferulic acid, coumaric acid, epigallocatechin gallate, quercetin, myricetin, and kaempferol were high with methanol extract. Since the flavonoid content of methanol extracts was high, the antioxidant potential, such as ABTS, and phosphomolybdenum activity increased. The plants antiviral activity against PRRSV was for the first time confirmed and the results revealed that methanol 25 µg and 75 to 100 µg in case of water extracts revealed antiviral activity.

    Full Text Available Background: India contributes a large proportion to global under-five child mortality. One of the determinants of child morbidity and mortality is the "child rearing practices." Socio-economic environment, child rearing practices and nutritional status play a synergistic role. Materials and Methods: Information was collected by exit interviews from married women attending out-patient departments of three primary health centers. Data was collected during December, 2009 using pretested questionnaire Married women in reproductive age group with youngest child in the age group of 1-5 years were eligible for inclusion. To assess the child rearing knowledge and practices (CRKP, a composite score was calculated based on 10 variables and categorized into satisfactory and unsatisfactory. Results: A total of 100 eligible married women were included in the study. About half of the women were in the age group of 25-35 years, 80% belonged to social class V and VI majority (63% were literate and 70% had ≥2 children. With the increase in literacy status, there was the increase in proportion of women who had satisfactory CRKP and decrease in proportion of women who had given pre-lacteal feed. Among women who had three children, 15 out of 39 (38% had fully immunized their first child as compared with 25 out of 39 (64% for the second child and 38 out of 39 (97% for the third child. Immunization coverage increased as the birth order increased. Conclusion: Mothers' education has a significant role in determining her child rearing practices, which in turn would lead better child survival.

    In this discussion of India attention is directed to the following: the people; geography; history; government; political conditions; the economy; foreign relations (Pakistan and Bangladesh, China, and the Soviet Union); defense; and the relations between the US and India. In 1983 India's population was estimated at 746 million with an annual growth rate of 2.24%. The infant mortality rate was estimated at 116/1000 in 1984 with a life expectancy of 54.9 years. Although India occupies only 2.4% of the world's land area, it supports nearly 15% of the world's population. 2 major ethnic strains predominate in India: the Aryan in the north and the Dravidian in the south, although the lines between them are blurred. India dominates the South Asian subcontinent geographically. The people of India have had a continuous civilization since about 2500 B.C., when the inhabitants of the Indus River Valley developed an urban culture based on commerce, trade, and, to a lesser degree, agriculture. This civilization declined about 1500 B.C. and Aryan tribes originating in central Asia absorbed parts of its culture as they spread out over the South Asian subcontinent. During the next few centuries, India flourished under several successive empires. The 1st British outpost in South Asia was established in 1619 at Surat on the northwestern coast of India. The British gradually expanded their influence until, by the 1850s, they controlled almost the entire area of present-day India. Independence was attained on August 15, 1947, and India became a dominion within the Commonwealth of Nations with Jawaharlal Nehru as prime minister. According to its constitution, India is a "sovereign socialist secular democratic republic." Like the US, India has a federal form of government, but the central government in India has greater power in relation to its states, and government is patterned after the British parliamentary system. The Congress Party has ruled India since independence with the

    Previous studies have not adequately captured the heterogeneous nature of the diabetes epidemic in India. The aim of the ongoing national Indian Council of Medical Research-INdia DIABetes study is to estimate the national prevalence of diabetes and prediabetes in India by estimating the prevalence by state. We used a stratified multistage design to obtain a community-based sample of 57 117 individuals aged 20 years or older. The sample population represented 14 of India's 28 states (eight from the mainland and six from the northeast of the country) and one union territory. States were sampled in a phased manner: phase I included Tamil Nadu, Chandigarh, Jharkhand, and Maharashtra, sampled between Nov 17, 2008, and April 16, 2010; phase II included Andhra Pradesh, Bihar, Gujarat, Karnataka, and Punjab, sampled between Sept 24, 2012, and July 26, 2013; and the northeastern phase included Assam, Mizoram, Arunachal Pradesh, Tripura, Manipur, and Meghalaya, with sampling done between Jan 5, 2012, and July 3, 2015. Capillary oral glucose tolerance tests were used to diagnose diabetes and prediabetes in accordance with WHO criteria. Our methods did not allow us to differentiate between type 1 and type 2 diabetes. The prevalence of diabetes in different states was assessed in relation to socioeconomic status (SES) of individuals and the per-capita gross domestic product (GDP) of each state. We used multiple logistic regression analysis to examine the association of various factors with the prevalence of diabetes and prediabetes. The overall prevalence of diabetes in all 15 states of India was 7·3% (95% CI 7·0-7·5). The prevalence of diabetes varied from 4·3% in Bihar (95% CI 3·7-5·0) to 10·0% (8·7-11·2) in Punjab and was higher in urban areas (11·2%, 10·6-11·8) than in rural areas (5·2%, 4·9-5·4; p<0·0001) and higher in mainland states (8·3%, 7·9-8·7) than in the northeast (5·9%, 5·5-6·2; p<0·0001).

  6. Water Management To Meet Challenges In Food Production ­ An Example From South India

    Science.gov (United States)

    Shadananan, K.

    Demands for food and water have been increasing with fast increasing population in many developing countries. Availability of water and fertile land, the two basic requirements for food production do not meet together in certain regions. In such regions, cooperation and efficient management practices can solve the problem to a good extend. The southern states of Kerala and Tamil Nadu of India are divided by the mountain chains, the Western Ghats the orography of which makes Kerala one among the heaviest rainfall region in the World itself and Tamil Nadu a scanty rainfall region. Kerala receives more than 300cm average annual rainfall, giving birth to a number of perennial rivers and other water bodies whereas Tamil Nadu receives rainfall less than100cm. Most of the rivers of Tamil Nadu are seasonal and it depends on interstate water transfer to face the permanent water shortage. Owing to the high density of population, peculiar topography and soil types, agricultural production in Kerala is quite inadequate and the State depends on neighbouring States, especially Tamil Nadu for rice and vegetables, but not willing to share water. According to the Constitution of India, control of rivers is by individual states and this often leads to transboundary water disputes that retard development activities. Around 80% of the rainfall of Kerala wastefully flows into the Sea, when there is acute water shortage in Tamil Nadu. All the rivers in Kerala originate in the Ghats and its steep slopes makes more water storage difficult. Cooperation among the States become essential for meeting the increasing needs in water and food. If some of the water from the catchments in Kerala is diverted into Tamil Nadu, and the States can do joint agriculture, it can meet the challenges due to increase in population and environmental changes and minimize unemployment problems. Water diversion to Tamil Naduwill reduce flood damage and soil erosion in Kerala. The existing socio

    Full Text Available Objective: To identify the associated factors of cervical pre-malignant lesions among the married fisher women residing in the coastal areas of Sadras, Tamil Nadu. Methods: The study was conducted in five fishermen communities under Sadras, a coastal area in Tamil Nadu, India. Two hundred and fifty married fisher women residing in the area. Quantitative descriptive approach with a cross-sectional study design was used. Data were collected using a structured interview schedule for identifying the associated factors and Pap smear test was performed for identifying the pre-malignant cervical lesions among the married fisher women. Data were analyzed using descriptive and inferential statistics. Results: Among 250 women, about six (2.4% of them presented with pre-cancerous lesions such as atypical squamous cell of undifferentiated significance (ASCUS - five (2% and mild dysplasia one (0.4%. Majority of the women, about 178 (71.2% women, had abnormal cervical findings. Statistical analysis showed a significant association of risk factors such as advanced age, lack of education, low socioeconomic status, using tobacco, multiparity, premarital sex, extramarital relationship, using cloth as sanitary napkin, etc. Conclusion: The study findings clearly show the increased vulnerable state of the fisher women for acquiring cervical cancer as they had many risk factors contributing to the same.

    Full Text Available Traditional cultural and economic ties between the Indian subcontinent and the Gulf region have existed for several centuries now. Strengthened further, both India and Pakistan continue to have important economic and strategic ties with the countries of the Gulf. While the Gulf region offers substantial economic advantages to both, they also have the potential to make positive interventions in the bilateral conflict between India and Pakistan. The following chapter analyses the role and position of the Gulf Arab States - in particular the member states of the Gulf Cooperation Council (GCC, and their potential in acting as a buffer for the Indo-Pak conflict. It will evaluate the official positions of the Gulf region towards various aspects of the Indo-Pak conflict. The Gulfcountries have often voiced their positions at regional and internationalforums. An additional aspect of this relationship is that the Gulf States are also members of the Organization of Islamic Conference (OIC, a pan- Islamic body which has often addressed issues of contention between India and Pakistan, particularly with respect to Kashmir. Through an academic understanding of the issues and incorporating viewpoints of experts in the area, the chapter seeks to provide fresh insights into an aspect which has the possibility of becoming a crucial incentive for peace between India and Pakistan.

    Full Text Available The Tamil Nadu model of public health is renowned for its success in providing quality health services at an affordable cost especially to the rural people. Tamil Nadu is the only state with a distinctive public health cadre in the district level and also the first state to enact a Public Health Act in 1939. Tamil Nadu has gained significant ground in the various aspects of health in the last few decades largely because of the significant reforms in its health sector which dates back to 1980s which saw rigorous expansion of rural health infrastructure in the state besides deployment of thousands of multipurpose health workers as village health nurses in rural areas. Effective implementation of Universal Immunization Programme, formation of Tamil Nadu Medical Services Corporation for regulating the drug procurement and promoting generic drugs, early incorporation of indigenous system of medicine into health care service, formulation of a health policy in 2003 by the state with special emphasis on low-income, disadvantaged communities alongside efficient implementation of The Tamil Nadu Health Systems Project (TNHSP are the major factors which contributed for the success of the state. The importance of good political commitment and leadership in the health gains of the state warrants special mention. Moreover, the economic growth of the state, improved literacy rate, gender equality, and lowered fertility rate in the last few decades and contributions from the private sector have their share in the public health success of the state. In spite of some flaws and challenges, the Tamil Nadu Model remains the prototype health care delivery system in resource-limited settings which can be emulated by other states also toward a better health care delivery system.

    Nasopharyngeal cancer (NPC) is a rare disease in most parts of the world, except for Southeast Asia, some parts of North Africa and the Arctic. It is mostly seen in people of Chinese origin. In India, NPC is also rare, except for the Hill States of Northeast India, particularly Nagaland, Manipur, and Mizoram. The striking feature of NPC in Northeast India is that the incidence ranges over the complete spectrum from the lowest (as 0.5/100 000 to 2.0/100 000 among Caucasoid) to the highest (as ~20/100 000 among Cantonese/Zhongshan dialect Chinese). The age-adjusted rate of NPC in Kohima district of Nagaland State is 19.4/100000, which is among the highest recorded rates. By contrast, in Assam, one of the so called Hill States but not itself a hilly state, NPC is much less common. The Northeastem region is distinguished by a preponderance of the Tibeto-Burman languages and by variable mongoloid features among peoples of the region. The nature of the migratory populations who are presumed to be bearers of the mongoloid risk is unknown, but these NPC occurrence features provide an outstanding opportunity for NPC risk investigation, such as that of the hypothesis of Wee et al. for westward displacement of Chinese aborigines following the last glacial maximum.

    2014-12-01

    Interdependency between water and energy is generally transacted in trade-off mode; where either of the resource gets affected because of the other. Generally this trade-off is commonly known as water-energy nexus. Many studies have been undertaken in various parts of the world using various approaches to tease out the intricate nexus. This research has adopted a different approach to quantify the inter-dependency. The adopted approach made an attempt to tease out the nexus from demand side for both the resources. For water demand assessment PODIUM Sim model was used and for other parameters available secondary data was used. Using this approach percentage share of water for energy and energy for water was estimated. For an informed decision making and sustainable development, assessment was carried out at state level as most of the policies are made specifically for the state. The research was done for the southernmost state of India, Tamil Nadu which is a rapidly growing industrial hub. Tamil Nadu is energy and water intensive state and the analysis shows that the share of water demand from energy sector compared to water demand from other major sectors is miniscule. While, the energy demand in water sector for various processes in different sectors compared to energy demand as total has a comparable share of range 15-25%. This analysis indicated the relative risk sectors face in competition for the resource. It point outs that water sector faces fierce competition with other sectors for energy. Moreover, the results of the study has assessed that state has negative water balance, which may make access to water more energy intensive with time. But, a projection into future scenario with an assumption based on the ongoing policy program of improving irrigation efficiency was made. It provided a solution of a potential positive equilibrium which conserves both water and energy. This scenario gave promising results which indicated less of water demand from

    Under the outbreak-based measles surveillance in Maharashtra State the National Institute of Virology at Pune receives 3-5 serum samples from each outbreak and samples from the local hospitals in Pune for laboratory diagnosis. This report describes one year data on the measles and rubella serology, virus isolation and genotyping. Maharashtra State Health Agencies investigated 98 suspected outbreaks between January-December 2013 in the 20 districts. Altogether, 491 serum samples were received from 20 districts and 126 suspected cases from local hospitals. Samples were tested for the measles and rubella IgM antibodies by commercial enzyme immunoassay (EIA). To understand the diagnostic utility, a subset of serum samples (n=53) was tested by measles focus reduction neutralization test (FRNT). Further, 37 throat swabs and 32 urine specimens were tested by measles reverse transcription (RT)-PCR and positive products were sequenced. Virus isolation was performed in Vero hSLAM cells. Of the 98 suspected measles outbreaks, 61 were confirmed as measles, 12 as rubella and 21 confirmed as the mixed outbreaks. Four outbreaks remained unconfirmed. Of the 126 cases from the local hospitals, 91 were confirmed for measles and three for rubella. Overall, 93.6 per cent (383/409) confirmed measles cases were in the age group of 0-15 yr. Measles virus was detected in 18 of 38 specimens obtained from the suspected cases. Sequencing of PCR products revealed circulation of D4 (n=9) and D8 (n=9) strains. Four measles viruses (three D4 & one D8) were isolated. Altogether, 94 measles and rubella outbreaks were confirmed in 2013 in the State of Maharasthra indicating the necessity to increase measles vaccine coverage in the State.

    Full Text Available Although India possesses the large volume of livestock, their productivity is abysmally low at global level. India, with its wide variation in geo-ecological parameters, elucidates a high variation in the productivity of its livestock, among regions. The compound growth rate of livestock productivity was worked out for the Southern Peninsular state of India, Tamil Nadu. The average productivity of milk in cross bred cows and buffaloes in Tamil Nadu was less than the national average, while the productivity desi cows was a bit a more. The annual compound growth rate of milk productivity among crossbred cows of Tamil Nadu was at meager 0.54 per cent during the period between 1998-1999 and 2006- 2007, whereas the productivity of milk in desi cows had improved from at an annual compound growth rate of 1.29 per cent. Notably, the milk productivity in buffaloes had declined at a rate of 0.29 per cent during the period under study. The annual compound growth of egg productivity in improved hens of Tamil Nadu was 20.87 per cent. The average annual productivity was 109.531 eggs, which improved from 70.623 in 1998-1999 to 197.084 in 2004-2005. Correspondingly, the productivity of desi hens also had a positive swing from the year 2003-2004 onwards. The results implied that the simulation of increased productivity, better farm financing and improved milk marketing could result in enhanced livestock production that would meet the future demands.

    1997-12-31

    Degradation and substantial losses to India`s forests have prompted a change in existing forestry management strategy. The new approach includes recognition of local participation in forestry management schemes but state control over most decisions is still dominant. Seen in terms of a common property resource system, India`s forests lack many of the factors usually considered inherent to successful management programs. Though India`s latest Forest Act affords more local involvement in forestry management, there continues to be an apparent lack of rights for local management groups over decision-making and the resource itself. Can this system enable the required balance between state and local management of India`s forests? 24 refs, 1 tab

    In India, the nature of interdependency between wife and husband is regarded as different from what it is in the west. It is observed that in Indian state of Bihar, there is co-existence of memory of domestic violence and attitudinal justification of domestic violence on all the dimensions of domestic violence. However, In Tamil Nadu, demographic transition is likely to create the differentiation and therefore significant co-existence of certain forms of attitude (attitudinal justification of beating for household chores, contraceptives, and sex refusal) and 'memories related to domestic violence' are not present there. Attitudinal assertion against domestic violence in the name of 'unfaithfulness' seems to be helping women both in Bihar & Tamil Nadu. However, in Tamil Nadu, if women raise her voice against beating by husband for sex refusal; her chance of facing domestic violence gets increased here. These kind of connect between violence and attitude is not present in Bihar. In Bihar, attitudinally if women assert their voice against violence for contraceptive decision making; it makes them to feel lesser amount of constant strain. The study shows the implications for reproductive health programme in India.

    2014-06-17

    We analyze variability in load and wind generation in India to assess its implications for grid integration of large scale wind projects using actual wind generation and load data from two states in India, Karnataka and Tamil Nadu. We compare the largest variations in load and net load (load ?wind, i.e., load after integrating wind) that the generation fleet has to meet. In Tamil Nadu, where wind capacity is about 53percent of the peak demand, we find that the additional variation added due to wind over the current variation in load is modest; if wind penetration reaches 15percent and 30percent by energy, the additional hourly variation is less than 0.5percent and 4.5percent of the peak demand respectively for 99percent of the time. For wind penetration of 15percent by energy, Tamil Nadu system is found to be capable of meeting the additional ramping requirement for 98.8percent of the time. Potential higher uncertainty in net load compared to load is found to have limited impact on ramping capability requirements of the system if coal plants can me ramped down to 50percent of their capacity. Load and wind aggregation in Tamil Nadu and Karnataka is found to lower the variation by at least 20percent indicating the benefits geographic diversification. These findings suggest modest additional flexible capacity requirements and costs for absorbing variation in wind power and indicate that the potential capacity support (if wind does not generate enough during peak periods) may be the issue that has more bearing on the economics of integrating wind

    2010-01-01

    Housing cooperatives became active in urban areas in Sweden, India and the United States during the interwar period. Yet, after the second world war, while housing cooperatives grew phenomenally nationwide in Sweden and India, they did not do so in the United States. This article makes a comparative institutional analysis of the evolution of housing cooperatives in these three countries. The analysis reveals that housing cooperatives' relationship with the state and the consequent support structures explain the divergent evolution. Although the relationships between cooperatives and the state evolved over time, they can be characterized as embedded autonomy, overembeddedness and disembeddedness in Sweden, India and the United States respectively. Whereas the consequent support structures for housing cooperatives became well developed in Sweden and India, such structures have been weak in the United States. The article highlights the need for embedded autonomy and the need for supportive structures to enable the growth of housing cooperatives.

    The 2004 Indian Ocean tsunami caused massive devastation and left a lasting impact along many of the major coastal regions in South Asia, including the coast of Tamil Nadu, a state in the southeastern tip of India. Following the event, sand deposits draped the low-lying areas and buried the muddy sediments of the coastal plain [Babu et al., 2007; Srinivasalu et al., 2007]. In addition, erosional features related to the tsunami, such as channels and scarps, have been observed along many parts of the coast (Figure 1a). This tsunami, along with a recorded history of intense monsoons, has highlighted the need for focused research on the role of extreme events in shaping the geological character of India's coastal plains.

    India's dependence on a climate sensitive sector like agriculture makes it highly vulnerable to its impacts. However, agriculture is highly heterogeneous across the country owing to regional disparities in exposure, sensitivity, and adaptive capacity. It is essential to know and quantify the possible impacts of changes in climate on crop yield for successful agricultural management and planning at a local scale. The Hadley Centre Global Environment Model version 2-Earth System (HadGEM-ES) was employed to generate regional climate projections for the study area using the Regional Climate Model (RCM) RegCM4.4. The dynamics in potential impacts at the sub-district level were evaluated using the Representative Concentration Pathway 4.5 (RCPs). The aim of this study was to simulate the crop yield under a plausible change in climate for the coastal areas of South India through the end of this century. The crop simulation model, the Decision Support System for Agrotechnology Transfer (DSSAT) 4.5, was used to understand the plausible impacts on the major crop yields of rice, groundnuts, and sugarcane under the RCP 4.5 trajectory. The findings reveal that under the RCP 4.5 scenario there will be decreases in the major C3 and C4 crop yields in the study area. This would affect not only the local food security, but the livelihood security as well. This necessitates timely planning to achieve sustainable crop productivity and livelihood security. On the other hand, this situation warrants appropriate adaptations and policy intervention at the sub-district level for achieving sustainable crop productivity in the future.

    Full Text Available The Nilgiri hills and adjoining downhill areas provide favourable ecological conditions for the propagation of haematophagous arthropods owing to richness in vegetation and animal activities. A study has been undertaken during 2008–2010 on the distribution and abundance of ticks of domestic animals in seven different biotopes. A total of 3,008 domestic animals were examined in areas ranging from an altitude of 300 to 2200 meters above mean sea level (MSL of which 1,335 (44.5% animals were having tick infestation. A total of 6,012 adult and immature ticks belonging to 12 species (11 ixodid and one argasid were collected. Eleven tick species were collected from Kallar area situated downhill eastern slopes of the Nilgiris followed by Burliar area (7 species located at higher altitudes. From Masinagudi area near to dense forests and scrub jungles, five species were recorded. However, at higher elevations on the hills, Udhagamandalam area, only one species was recorded. Among various tick species recorded in the study, Boophilus microplus was distributed in almost all areas surveyed followed by Haemaphysalis spinigera and Rhipicephalus sanguineus. The factors governing their distribution and epidemiological significance in the transmission of various tick-borne diseases of public health importance are discussed.

    The burden of social inequality falls disproportionately on child health and survival. This inequality raises the question of how wide this gap is, or what its relation is with the level of child mortality. Whether these disparities are increasing or declining with the development and how they differ from region to region or from state to state within the country needs to be looked into. As a measure of inequality and to compare the disparities between different states of India, concentration curves and indices are constructed from infant and under five mortality data classified under different quintiles of wealth index from the National Family Health Survey (NFHS-3) data of India. Inequality measures indicate that inequality in child mortality is more concentrated in the comparatively developed states than the poorer states in India.

    This study uses the second National Family Health Survey of India to estimate the effect of state-level public health spending on mortality across all age groups, controlling for individual, household, and state-level covariates. We use a state's gross fiscal deficit as an instrument for its health spending. Our study shows a 10% increase in public spending on health in India decreases the average probability of death by about 2%, with effects mainly on the young, the elderly, and women. Other major factors affecting mortality are rural residence, household poverty, and access to toilet facilities.

    India has an estimated geothermal power potential of 10,600 MWe, but this potential is entirely undeveloped at present. The 'Geothermal Atlas of India' prepared by the Geological Survey of India (GSI) in 1991 describes some 340 hot spring sites and identifies more than 300 sites with geothermal potential in at least seven key geothermal provinces throughout India. There are more than 20 hot spring sites in Jammu & Kashmir State, mainly in the Chenab Valley in the Lesser/Central Himalaya, the Kashmir Valley and in the High Himalaya region of Ladakh. At least three localities in the Ladakh region - Chamuthang and Puga in the Indus valley and Panamik in the Nubra Valley - are considered to have geothermal power generation potential of between 3 and > 20 MWe.

    2012-05-01

    The rapid growth of the construction industry in India has influenced key players in the industry to adopt alternative technologies addressing time, cost and quality. The rising demand in housing, infrastructure and other facilities have further highlighted the need for the construction industry to look at adopting alternate building technologies. Offsite construction has evolved as a panacea to dealing with the under-supply and poor quality in the current age construction industry. Several offsite techniques have been adopted by the construction sector. Although, different forms of offsite techniques have been around for a while but their uptake has been low in the Indian context. This paper presents the perceptions about offsite construction in India and highlights some of the barriers and drivers facing the Indian construction industry. The data was gathered through a survey of 17 high level managers from some of the largest stakeholder organizations of the construction sector in India. The influence of time and cost has been highlighted as a major factor fuelling the adoption of offsite construction. However, the influence of current planning systems and the need for a paradigm shift are some of the prominent barriers towards the adoption of offsite techniques.

    India is often thought of as a development paradox with relatively high economic growth rates in the past few years, but with lower progress in areas of life expectancy, education and standard of living. While serious inequalities in growth, development and opportunity explain the illusion of the paradox at the country level, still, a significant proportion of the world's poor live in India, as do a significant proportion of the world's malnourished children. Poverty and undernutrition coexist, and poor dietary quality is associated with poor childhood growth, as well as significant micronutrient deficiencies. Food security is particularly vulnerable to changes in the economic scenario and to inequities in wealth distribution. Migration from rural to urban settings with a large informal employment sector also ensures that migrants continue to live in food insecure situations. While food production has for the most part kept pace with the increasing population, it has been with regard to cereal rather than of pulses and millet production. Oil seeds, sugar cane and horticultural crops, along with non-food crops are also being promoted, which do not address nutrition security, and, coupled with the increase in the consumption of pre-prepared food, may indeed predispose towards the double burden of malnutrition. Access to food is also particularly susceptible to poverty and inequality. Many strategies and policies have been proposed to counter undernutrition in India, but their implementation has not been uniform, and it is still too early to assess their lasting impact at scale.

    The coastal zone is one of the nation's greatest environmental and economic assets. The present research aims at studying the shoreline changes along Vedaranyam coast using conventional and modern techniques including field sampling, remote sensing, and geographical information system (GIS). The study area was divided into three zones. Dynamic Land/Sea polygon analysis was performed to obtain the shore line changes at different time periods between 1930 and 2005. From the multidate shoreline maps, the rate of shoreline change was computed using linear regression rate and end point rate. Further, the shoreline was classified into eroding, accreting, and stable regions through GIS analysis. The eroding, accreting, and stable coastal stretch along Vedaranyam is observed as 18 %, 80.5 %, and 1.5 %, respectively. Net shoreline movement is seaward, i.e., the coast is progressive with an average rate of 5 m/year. A maximum shoreline displacement of 1.3 km towards the sea is observed near Point Calimere. During the Asian Tsunami 2004, the eastern part of the study area showed high erosion. Sediment transport paths derived from the grain size analysis of beach sediments collected during different seasons help to identify the major sediment source and sinks. Point Calimere acts as the major sink for sediments whereas Agastiyampalli and Kodiakkarai are found to be the major sources for the sediment supply along the Vedaranyam coast. Shoreline change study from field and satellite data using GIS analysis confirms that Vedaranyam coast is accreting in nature.

    Full Text Available Indian summer monsoon (ISM plays an important role in the weather and climate system over India. The rainfall during monsoon season controls many sectors from agriculture, food, energy, and water, to the management of disasters. Being a coastal province on the eastern side of India, Odisha is one of the most important states affected by the monsoon rainfall and associated hydro-meteorological systems. The variability of monsoon rainfall is highly unpredictable at multiple scales both in space and time. In this study, the monsoon variability over the state of Odisha is studied using the daily gridded rainfall data from India Meteorological Department (IMD. A comparative analysis of the behaviour of monsoon rainfall at a larger scale (India, regional scale (Odisha, and sub-regional scale (zones of Odisha is carried out in terms of the seasonal cycle of monsoon rainfall and its interannual variability. It is seen that there is no synchronization in the seasonal monsoon category (normal/excess/deficit when analysed over large (India and regional (Odisha scales. The impact of El Niño, La Niña, and the Indian Ocean Dipole (IOD on the monsoon rainfall at both scales (large scale and regional scale is analysed and compared. The results show that the impact is much more for rainfall over India, but it has no such relation with the rainfall over Odisha. It is also observed that there is a positive (negative relation of the IOD with the seasonal monsoon rainfall variability over Odisha (India. The correlation between the IAV of monsoon rainfall between the large scale and regional scale was found to be 0.46 with a phase synchronization of 63%. IAV on a sub-regional scale is also presented.

    Full Text Available Background: Areca nut is the fourth main psychoactive substance in the world. In India, tobacco is added to the quid, and the commercially manufactured nonperishable forms of betel quid (pan masala or gutkha are on the rise in the market. Objective : To find out the prevalence of areca nut among the rural residents of Sriperambudur Taluk . Settings and Design: A community-based survey using pre-tested semi-structured questionnaire. Materials and Methods :0 The survey was conducted in 2 villages and their colonies, which were randomly selected out of 168 villages. Data was collected from 500 residents of the study population. The survey was conducted for a period of 2 months. Statistical Analysis: SPSS version 10.0. Results :The study participants were more likely to initiate areca nut use by 22 years of age. As many as 19.8% (n = 99 of the study participants chewed areca nut products, out of whom 11.2% (n = 56 indulged in chewing habit alone (areca nut products. Areca nut use was higher among male study subjects compared to females. The commercial forms of areca nut products (gutkha were the most prevalent ones [47.5% (n = 47 of those who used areca nut] observed in the community. Compared to female participants, male participants were more likely to perceive areca nut use as the most harmful habit draining the community health and wealth. Conclusion :There seems to be an increase in the prevalence of areca nut use. The community also perceives it to be a harmful habit. Therefore, effective interventions should be targeted towards the high-risk subpopulation of the community to decrease the prevalence of areca nut use in rural Tamil Nadu.

    Full Text Available In India, the healthcare delivery system starts up from the sub-center at the village level and reaches up to super specialty medical centers providing state of the art emergency medical services (EMS. These highest centers, located in big cities, are considered the last referral points for the patients from nearby cities and states. As the incidents of rail and road accidents have increased in recent years, the role of EMS becomes critical in saving precious lives. But when the facilities and management of these emergency centers succumbs before the patient, then the question arises regarding the adequate availability and quality of EMS. The death of an unknown common man, Rambhor, for want of EMS in three big hospitals in the national capital of India put a big question on the "health" of the emergency health services in India. The emergency services infrastructure seems inadequate and quality and timely provision of EMS to critical patients appears unsatisfactory. There is lack of emergency medicine (EM specialists in India and also the postgraduation courses in EM have not gained foot in our medical education system. Creation of a Centralized Medical Emergency Body, implementation of management techniques, modification of medical curriculum, and fixing accountability are some of the few steps which are required to improve the EMS in India.

  20. The state of political priority for safe motherhood in India.

    2007-07-01

    Approximately one-quarter of all maternal deaths occur in India, far more than in any other nation on earth. Until 2005, maternal mortality reduction was not a priority in the country. In that year, the cause emerged on the national political agenda in a meaningful way for the first time. An unpredictable confluence of events concerning problem definition, policy alternative generation and politics led to this outcome. By 2005, evidence had accumulated that maternal mortality in India was stagnating and that existing initiatives were not addressing the problem effectively. Also in that year, national government officials and donors came to a consensus on a strategy to address the problem. In addition, a new government with social equity aims came to power in 2004, and in 2005, it began a national initiative to expand healthcare access to the poor in rural areas. The convergence of these developments pushed the issue on to the national agenda. This paper draws on public policy theory to analyse the Indian experience and to develop guidance for safe motherhood policy communities in other high maternal mortality countries seeking to make this cause a political priority.

    Jharkhand is one of the eastern states of India which has an agriculture-based economy. Uncertain and erratic distribution of precipitation as well as a lack of state water resources planning is the major limitation to crop growth in the region. In this study, the spatial and temporal variability in precipitation in the state was examined using a monthly precipitation time series of 111 years (1901-2011) from 18 meteorological stations. Autocorrelation and Mann-Kendall/modified Mann-Kendall tests were utilized to detect possible trends, and the Theil and Sen slope estimator test was used to determine the magnitude of change over the entire time series. The most probable change year (change point) was detected using the Pettitt-Mann-Whitney test, and the entire time series was sub-divided into two parts: before and after the change point. Arc-Map 9.3 software was utilized to assess the spatial patterns of the trends over the entire state. Annual precipitation exhibited a decreasing trend in 5 out of 18 stations during the whole period. For annual, monsoon and winter periods of precipitation, the slope test indicated a decreasing trend for all stations during 1901-2011. The highest variability was observed in post-monsoon precipitation (77.87 %) and the lowest variability was observed in the annual series (15.76 %) over the 111 years. An increasing trend in precipitation in the state was found during the period 1901-1949, which was reversed during the subsequent period (1950-2011).

Globalization and liberalization policies of the government in 90's have increased the number of road vehicles nearly 92.6% from 1980-1981 to 2003-2004. These vehicles mainly consume non-renewable fossil fuels, and are a major contributor of green house gases, particularly CO 2 emission. This paper focuses on the statewise road transport emissions (CO 2, CH 4, CO, NO x, N 2O, SO 2, PM and HC), using region specific mass emission factors for each type of vehicles. The country level emissions (CO 2, CH 4, CO, NO x, N 2O, SO 2 and NMVOC) are calculated for railways, shipping and airway, based on fuel types. In India, transport sector emits an estimated 258.10 Tg of CO 2, of which 94.5% was contributed by road transport (2003-2004). Among all the states and Union Territories, Maharashtra's contribution is the largest, 28.85 Tg (11.8%) of CO 2, followed by Tamil Nadu 26.41 Tg (10.8%), Gujarat 23.31 Tg (9.6%), Uttar Pradesh 17.42 Tg (7.1%), Rajasthan 15.17 Tg (6.22%) and, Karnataka 15.09 Tg (6.19%). These six states account for 51.8% of the CO 2 emissions from road transport.

    Tectonic stress regime in the Shillong plateau, northeast region of India, is examined by stress tensor inversion. Some 97 reliable fault plane solutions are used for stress inversion by the Michael and Gauss methods. Although an overall NNW-SSE compressional stress is observed in the area, the stress regime varies from western part to eastern part of the plateau. The eastern part of the plateau is dominated by NNE-SSW compression and the western part by NNW-SSE compression. The NNW-SSE compression in the western part may be due to the tectonic loading induced by the Himalayan orogeny in the north, and the NNE-SSW compression in the eastern part may be attributed to the influence of oblique convergence of the Indian plate beneath the Indo-Burma ranges. Further, Gravitational Potential Energy (GPE) derived stress also indicates a variation from west to east.

    At the international level, India is emerging as a key actor in climate negotiations, while at the national and sub-national levels, the climate policy landscape is becoming more active and more ambitious. It is essential to unravel this complex landscape if we are to understand why policy looks the way it does, and the extent to which India might contribute to a future international framework for tackling climate change as well as how international parties might cooperate with and support India's domestic efforts. Drawing on both primary and secondary data, this paper analyzes the material and ideational drivers that are most strongly influencing policy choices at different levels, from international negotiations down to individual states. We argue that at each level of decision making in India, climate policy is embedded in wider policy concerns. In the international realm, it is being woven into broader foreign policy strategy, while domestically, it is being shaped to serve national and sub-national development interests. While our analysis highlights some common drivers at all levels, it also finds that their influences over policy are not uniform across the different arenas, and in some cases, they work in different ways at different levels of policy. We also indicate what this may mean for the likely acceptability within India of various climate policies being pushed at the international level.

    This study was conducted to analyze and identify differences in the palatal rugae patterns and to identify gender wise changes in the palatal rugae shapes in populations of five different states of India. Study was conducted in five different Indian states. 500 sample subjects from Andhra Pradesh, Tamil Nadu, Karnataka, Madhya Pradesh and Maharashtra were included. Rugae patterns with predominant shapes were analyzed and categorized according to different states and both genders, data was statistically analyzed using SPSS software 15.0 and the results were obtained by Chi-square analysis. "Wavy" type of palatal rugae pattern is the most predominant variant in five different study groups in both the genders. This study could identify variations in distribution of various palatal rugae pattern in five different states and confirmed the "wavy" type of palatal rugae patterns to be the most predominant variant in five different study groups.

    Nearly 300,000 women die from pregnancy-related complications each year. One-fifth of these deaths occur in India. Maternal survival rose on India's national policy agenda in the mid-2000s, but responsibility for health policy and implementation in the federal system is largely devolved to the state level where priority for the issue and maternal health outcomes vary. This study investigates sources of variation in maternal health policy and implementation sub-nationally in India. The study is guided by four analytical categories drawn from policy process literature: constitutional, governing and social structures; political contexts; actors and ideas. The experiences of two south Indian states-Tamil Nadu a leader and Karnataka a relatively slow mover-are examined. Process-tracing, a case study methodology that helps to identify roles of complex historical events in causal processes, was employed to investigate the research question in each state. The study is informed by interviews with public health policy experts and service delivery professionals, observation of implementation sites and archival document analysis. Historical legacies-Tamil Nadu's non-Brahmin social movement and Karnataka's developmental disparities combined with decentralization-shape the states' political contexts, affecting variation in maternal health policy and implementation. Competition to advance consistent political priorities across regimes in Tamil Nadu offers fertile ground for policy entrepreneurship and strong public health system administration facilitates progress. Inconsistent political priorities and relatively weak public health system administration frustrate progress in Karnataka. These variations offer insights to the ways in which sub-national political and administrative contexts shape health policy and implementation.

    This article describes how local responses to global health initiatives on infant feeding for HIV-positive mothers reflect and transform sociocultural values in Tamil Nadu, India. Drawing from ethnographic research conducted from 2002 to 2008, the article compares guidelines for counseling HIV-positive mothers established by UNICEF and WHO with decision-making processes and perceptions of HIV-positive mothers. In addition to the financial considerations, three factors are identified as impinging on this decision: (1) a strong sociocultural value in favor of breastfeeding linked to historical traditions and contemporary state and international development discourses, (2) constructions of class identity, (3) the influence of a rights-based discourse in HIV/AIDS advocacy. This wide range of factors points to the difficulty of implementing the international protocols. This is the first study of its kind to closely examine the complex determinants in HIV-positive women's decisions and evaluations of infant feeding methods in India.

    Full Text Available The present investigation was carried out in Poondi reservoir, Tamil Nadu, for a period of 8 months from September, 2014 to April, 2015 where the cage culture has been already initiated by the state fisheries department. The water and sediment samples were collected from the reservoir at point and non- point sources of the cage culture units and were analyzed for their physico-chemical parameters. The total microbial load, E. coli and feacal streptococci population were also assessed from the reservoir. During the study period, pH, sulphate, nitrate and BOD values were found within the permissible range for drinking water quality. The alkalinity values were found optimum in the reservoir water. The sediment characteristics such as pH, electrical conductivity, total organic carbon and available phosphorus values were also found to be within the standard limit. The optimum water and sediment quality characteristics and the absence of E. coli and feacal streptococci observed in the cage culture unit clearly showed that the small cage farming in the reservoir does not have major environmental impacts on the water and sediment quality.

    A total of 85 samples (58.0 %) were found to be positive for Canine parvovirus (CPV) by PCR assay (Hfor/Hrev primers) out of 158 suspected faecal samples of dogs collected from various states/union territories of India. Nine CPV isolates could be obtained in A-72 cell line. The sequencing of the partial VP2 gene of CPV identified the predominant CPV strain as CPV-2a (Ser297Ala) with one CPV-2b (Ser297Ala) and another CPV-2a variant strain (Ser297Gly). Several non-synonymous and synonymous mutations were also recorded in this study. The phylogenetic tree revealed that most of the CPV sequences from Tamil Nadu (Southern India) and Maharashtra (Western India) obtained during 2011 and few sequences from Northern India obtained during 2012 were grouped together along with CPV-2a (Ser297Ala) strains from China and India and followed the same evolution; although there was definitive indication of separate lineages too by few other sequences.

    Full Text Available Background: Communities affected by chronic drought conditions face a wide variety of challenges including an adverse effect on their nutritional status. The Government of India, during the year 2002-03, declared nine States viz., Andhra Pradesh, Karnataka, Tamil Nadu, Madhya Pradesh, Maharashtra, Rajasthan, Gujarat, Chhattisgarh and Orissa as drought affected. Material and Methods: At the request of Department of Agriculture, Government of India, a rapid community based cross-sectional study was carried out adopting multistage random sampling procedure with the objective to assess the nutritional status of community in these nine chronic drought affected states in India. Results: In general, the intakes of all the nutrients were grossly deficit as against their RDAs. The nutrition intervention programmes initiated by the Government of India, in general, contributed to meet the daily requirement of staples like cereals & millets in most of the States. Conclusion: In drought-affected areas, where the level of famine impact is unknown, an early rapid assessment of the nutritional status and the health needs of the population are critical to estimate the degree of impact to plan timely and appropriate interventions.

    Background: There is a paucity of information on the availability of services for diagnosis and management of diabetic retinopathy (DR) in India. Objectives: The study was undertaken to document existing healthcare infrastructure and practice patterns for managing DR. Methods: This cross-sectional study was conducted in 11 cities and included public and private eye care providers. Both multispecialty and stand-alone eye care facilities were included. Information was collected on the processes used in all steps of the program, from how diabetics were identified for screening through to policies about follow-up after treatment by administering a semistructured questionnaire and by using observational checklists. Results: A total of 86 eye units were included (31.4% multispecialty hospitals; 68.6% stand-alone clinics). The availability of a dedicated retina unit was reported by 68.6% (59) facilities. The mean number of outpatient consultations per year was 45,909 per responding facility, with nearly half being new registrations. A mean of 631 persons with sight-threatening-DR (ST-DR) were registered per year per facility. The commonest treatment for ST-DR was laser photocoagulation. Only 58% of the facilities reported having a full-time retina specialist on their rolls. More than half the eye care facilities (47; 54.6%) reported that their ophthalmologists would like further training in retina. Half (51.6%) of the facilities stated that they needed laser or surgical equipment. About 46.5% of the hospitals had a system to track patients needing treatment or for follow-up. Conclusions: The study highlighted existing gaps in service provision at eye care facilities in India. PMID:27144134

    The United States and India have among the largest economies in the world, and they continue to work together to address current and future challenges in reliable electricity supply. The acceleration to efficient, grid-responsive, resilient buildings represents a key energy security objective for federal and state agencies in both countries. The weaknesses in the Indian grid system were manifest in 2012, in the country’s worst blackout, which jeopardized the lives of half of India’s 1.2 billion people. While both countries are investing significantly in power sector reform, India, by virtue of its colossal growth rate in commercial energy intensity and commercial floor space, is better placed than the United States to integrate and test state-of-art Smart Grid technologies in its future grid-responsive commercial buildings. This paper presents a roadmap of technical collaboration between the research organizations, and public-private stakeholders in both countries to accelerate the building-to-grid integration through pilot studies in India.

    Background. India is the highest contributor to child anemia. About 89 million children in India are anemic. The study determines the factors that contributed to child anemia and examines the role of the existing programs in reducing the prevalence of child anemia particularly in the EAG states. Methods. The data from the latest round of the National Family Health Survey (NFHS-3) is used. Simple bivariate and multinomial logistics regression analyses are used. Results. About 70% children are anemic in all the EAG states. The prevalence of severe anemia is the highest (6.7%) in Rajasthan followed by Uttar Pradesh (3.6%) and Madhya Pradesh (3.4%). Children aged 12 to 17 months are significantly seven times (RR = 7.99, P children of 36 to 59 months. Children of severely anemic mothers are also found to be more severely anemic (RR = 15.97, P children of not anemic mothers. Conclusions. The study reveals that the existing government program fails to control anemia among preschool children in the backward states of India. Therefore, there is an urgent need for monitoring of program in regular interval, particularly for EAG states to reduce the prevalence of anemia among preschool children.

    "In this paper an attempt has been made to estimate return migration from the destination state of migrants for 15 major Indian states during 1961-71 among the life-time inter-state migrants enumerated in the 1961 census. The model used for estimation is based on the procedure suggested by Zachariah (1967) for estimating return migration from two census data." The results indicate that of the almost 13 million interstate migrants enumerated in the 1961 census, about 4.7 million returned during the period 1961-1971. Factors affecting this return migration are considered.

    This article discusses the nature, magnitude, causes, and consequences of female child prostitution in India and offers measures for control and prevention of girl prostitution. Data are obtained from the 6-city study of prostitution and the author's own research. An estimated 85% of all prostitutes in Calcutta and Delhi entered the work at an early age. The numbers are rising. The promotion of tourism is linked with prostitution. Girl prostitutes are primarily located in low-middle income areas and business districts and are known by officials. Brothel keepers regularly recruit young girls. An estimated 33% of prostitutes are young girls. In Bangalore, Calcutta, Delhi, and Hyderabad, there are an estimated 10,000 girl prostitutes. UNICEF estimates about 300,000 child prostitutes. Girl prostitutes are grouped as common prostitutes, singers and dancers, call girls, religious prostitutes or devdasi, and caged brothel prostitutes. Religious prostitutes are mainly found in the South. Caged ones are found in Bombay. A little over 50% of prostitutes come from other countries, such as Nepal and Bangladesh. The girls tend to come from urban slums and poor rural areas. High prostitute supply regions include Andhra Pradesh, Karnataka, Maharashtra, Uttar Pradesh, Tamil Nadu, and West Bengel states. About 85% are Hindus, and about 66% are from scheduled castes and tribes. Bangalore and Bombay have a higher proportion of girl prostitutes. The causes of prostitution include ill treatment by parents, bad company, family prostitutes, social customs, inability to arrange marriage, lack of sex education, media, prior incest and rape, early marriage and desertion, lack of recreational facilities, ignorance, and acceptance of prostitution. Economic causes include poverty and economic distress. Psychological causes include desire for physical pleasure, greed, and dejection. Most enter involuntarily. A brief profile is given of the life of a prostitute.

    1994-01-01

    Tamil Nadu had a 1991 annual growth rate of 1.1% compared to a rate of over 2% in the northern states of Madhya Pradesh, Bihar, Rajasthan, and Uttar Pradesh. The lower fertility and mortality in Tamil Nadu was achieved through a sustained, multifaceted social and economic effort and through promotion, reach, and quality of family planning in a short time period. Political leadership and media efforts since the 1960s have strengthened support for the small family norm, later marriage, and improved status of women. Infrastructure development includes roads and water supplies in every village, rural electrification, and a government center in every village. Tamil Nadu devotes over 33% of its total budget to health and education. Special emphasis was placed on a program initiated in 1982 to provide a nutritious midday meal in school to every child living in poverty. In 1994, this program cost Rs. 3350. The result has been increasing school enrollment, greater retention of female children, reductions in malnutrition, and opportunities for local part-time employment and increased social status in the community. In some locations, the meal program includes day care centers and meals for the aged. Another social program provides cash loans of Rs. 5000 to couples at first marriage who are over the age of 18 years with a completed high school degree. Rs. 300 are provided for nutritional support for the first two pregnancies. Rs. 10,000 are also given to girls whose family income is under Rs. 12,000 a year. Financial assistance is available for widows who remarry and for intercaste marriages. A new program provides a gold ring, educational expenses, and Rs. 20 for families with an only girl child or two girl children and which accept a permanent method of family planning. A negligible 20,000 couples joined the program, although about 15% of the total population was eligible. 50-55% of women receive state subsidies and loans. Collectives exist in 12,000 women's groups.

    Brijesh C. Purohit

    2009-11-01

    Full Text Available In recent years, WHO and other individual researchers have advocated estimation of health system performance through stochastic frontier models. It provides an idealized yardstick to evaluate economic performance of health system. So far attempts in India have remained focused at state level analysis. This paper attempts a sub-state level analysis for an affluent Indian state, namely Punjab, by using stochastic frontier technique. Our results provide pertinent insight into state health system and facilitate health facility planning at the sub-state level. Carried out in two stages of estimation, our results suggest that life expectancy in the Indian state could be enhanced considerably by correcting the factors that are adversely influencing the sub-state level health system efficiency. A higher budgetary allocation for health manpower is recommended by us to improve efficiency in poorly performing districts. This may be supported by policy initiatives outside the health system by empowering women through better education and work participation.

    Full Text Available Objective: To assess the incidence of cleft lip and palate defects in the state of Andhra Pradesh, India. Design Setting: The study was conducted in 2001 in the state of Andhra Pradesh, India. The state has a population of 76 million. Three districts, Cuddapah, Medak and Krishna, were identified for this study owing to their diversity. They were urban, semi-urban and rural, respectively. Literacy rates and consanguinity of the parents was elicited and was compared to national averages to find correlations to cleft births. Type and side of cleft were recorded to compare with other studies around the world and other parts of India. Results: The birth rate of clefts was found to be 1.09 for every 1000 live births. This study found that 65% of the children born with clefts were males. The distribution of the type of cleft showed 33% had CL, 64% had CLP, 2% had CP and 1% had rare craniofacial clefts. Unilateral cleft lips were found in 79% of the patients. Of the unilateral cleft lips 64% were left sided. There was a significant correlation of children with clefts being born to parents who shared a consanguineous relationship and those who were illiterate with the odds ratio between 5.25 and 7.21 for consanguinity and between 1.55 and 5.85 for illiteracy, respectively. Conclusion: The birth rate of clefts was found to be comparable with other Asian studies, but lower than found in other studies in Caucasian populations and higher than in African populations. The incidence was found to be similar to other studies done in other parts of India. The distribution over the various types of cleft was comparable to that found in other studies.

    Incidence of sickle cell trait in India is high in peninsular south, south-eastern, central and south-western India, while in north and north-eastern India, it is absent. Unicentric origin of SCD in the tribals of nilgiri hills in southern India has been proposed. The present study on the frequency of HbS trait and beta-globin gene haplotypes was conducted in the tribal-rich states of Chhattisgarh and Jharkhand to get an insight into the uneven distribution of HbS in India. Jharkhand borders with the HbS-high Odisha and Chhattisgarh, and HbS-low UP, Bihar and Bengal. Cellulose acetate gel electrophoresis was performed on the collected blood samples, to detect sickle haemoglobin (HbS) followed by DNA analysis. HbS associated beta-gene haplotype was constructed for the samples positive for HbS and all the tribals by PCR-RFLP. Out of 805 (Chhattisgarh - 261, Jharkhand - 544; greater than 36 percent tribals) samples analysed HbS frequency was 13 percent in Chhattisgarh and 3.3 percent in Jharkhand. Within Jharkhand, frequencies varied considerably from 10 percent in Tatanagar to nil in Sahibganj. The Arab-India (AI) haplotype of beta-globin cluster occurred in low frequency, confined mainly to Chhattisgarh. The most abundant haplotype in all the populations was the East Asian, + - - - - - +, rare in HbS, mainly in Sahibganj in east Jharkhand, which lacked AI. Our results indicate that besides the heterozygote advantage againstmalaria, the uneven regional distribution of HbS trait is because of restricted movement of two different populations, Dravidian from the south and Tibeto-Burman from the east into the Indianmainland which failed tomeet, we conjecture, due to severe climatic conditions (deserts and heat) prevailing through parts of central India. Apparently, Jharkhand became a zone of contact between them in recent times.

Cellulose acetate gel electrophoresis was performed on the collected blood samples, to detect sickle haemoglobin (HbS) followed by DNA analysis. HbS associated -gene haplotype was constructed for the samples positive for HbS and all the tribals by PCR-RFLP. Out of 805 (Chhattisgarh – 261, Jharkhand – 544; >36% tribals) samples analysed HbS frequency was 13% in Chhattisgarh and 3.3% in Jharkhand. Within Jharkhand, frequencies varied considerably from 10% in Tatanagar to nil in Sahibganj. The Arab-India (AI) haplotype of -globin cluster occurred in low frequency, confined mainly to Chhattisgarh. The most abundant haplotype in all the populations was the East Asian, + − − − − − +, rare in HbS, mainly in Sahibganj in east Jharkhand, which lacked AI. Our results indicate that besides the heterozygote advantage againstmalaria, the uneven regional distribution of HbS trait is because of restricted movement of two different populations, Dravidian from the south and Tibeto-Burman from the east into the Indianmainland which failed tomeet, we conjecture, due to severe climatic conditions (deserts and heat) prevailing through parts of central India. Apparently, Jharkhand became a zone of contact between them in recent times.

    Past efforts invested in computer-based education technology interventions have generated little evidence of affordable success at scale. This paper presents the results of a mobile phone-based intervention conducted in the Indian states of Andhra Pradesh and Tamil Nadu in 2012-13. The BridgeIT project provided a pool of audio-visual learning materials organised in accordance with a system of syllabi pacing charts. Teachers of Standard 5 and 6 English and Science classes were notified of the availability of new videos via text messages (SMS), which they downloaded onto their phones using an open-source application and showed, with suggested activities, to students on a TV screen using a TV-out cable. In their evaluation of this project, the authors of this paper found that the test scores of children who experienced the intervention improved by 0.36 standard deviations in English and 0.98 standard deviations in Science in Andhra Pradesh, relative to students in similar classrooms who did not experience the intervention. Differences between treatment and control schools in Tamil Nadu were less marked. The intervention was also cost-effective, relative to other computer-based interventions. Based on these results, the authors argue that is possible to use mobile phones to produce a strong positive and statistically significant effect in terms of teaching and learning quality across a large number of classrooms in India at a lower cost per student than past computer-based interventions.

    Full Text Available Tourism is a powerful economic development tool which creates jobs, provides new business opportunities and strengthens local economies. Starting with the local culture and already existing communities and geographies, tourism developments can enhance the interesting and unique aspects of a location. Using local traditions, beliefs, and resources reinforces the cultural heritage of a location, making these new areas thriving cultural hubs. These communities hold the social values of the residents that connect them to their culture and history, and they also promote the education of these values, which attracts tourists and visitors who are interested in understanding local culture. This increased flow of people boosts local businesses, which in turn supports the community by building a strong economic foundation, allowing the local culture to flourish and create an even more vibrant community. It is now well admired worldwide that development and management of tourism at any destination or place, requires a multi-dimensional approach (strengthen the institutional capacity, engage with multiple stakeholders, establish appropriate protocols and systems. When cultural heritage tourism development is done right, it also helps to protect our nation’s natural and cultural treasures and improve the quality of life for residents and visitors. Linking tourism with heritage and culture can do more for local economies than promoting them separately. This article explores the ethnic heritage and emphasizes on the holistic tourism development approach after considering the various heritage tourism resources available in the state.

    Glanders, a notifiable highly contagious disease primarily of equids, is a disease of high zoonotic importance. Caused by gram-negative bacillus, Burkholderia mallei, the disease was restricted to certain pockets of India with sporadic cases. Recently, a major outbreak of glanders occurred in India starting from Maharashtra. Following clinical signs and symptoms and laboratory investigations on serum, nasal swab and pus swab samples, it was confirmed as glanders among equines in Pune and Panchgani areas of Maharashtra. One pus sample and three nasal swabs yielded B. mallei isolates while 23 serum samples were found positive for glanders by complement fixation test (CFT). The disease was successfully controlled in the state by following strategies for prevention of spread of the disease to other areas in accordance with Glanders and Farcy Act, 1899. Follow up of the occurrence in Maharashtra revealed negative status based on testing and physical surveillance on more than 3,500 equines thereafter. Investigations indicated that the nidus of infection may be present elsewhere in North India.

  2. Organizing for rural energy development: Improved cookstoves, local organizations, and the state in Gujarat, India

    1990-01-01

    Proponents of the sustainable development of Third World States frequently urge the integration of local non-government organizations (NGOs) into State-sponsored, centrally administered programs of rural-resource development. This study draws on literatures on energy use, biomass technologies, and organization theory, and on interviews, archival research, and organizational surveys of eight Gujarati NGOs conducted in India in 1986 and 1987. It concludes that the conventional wisdom guiding State-NGO collaboration is in important ways flawed. Though driven by political and fiscal imperatives to integrate local NGOs in State programs, national planners are ill-equipped to cope with the uncertainty and vulnerability such collaboration brings. Their understandable response is to structure collaboration in ways inimical to overarching goals of local participation and flexible administration. Simultaneously, at the local level, unmanaged systems of collaboration - organized around a view of local organizations as self-guiding and self-correcting - generates a degradation of capacity. Organizational assumptions driving the sustainable development of India's (and much of the Third World's) rural energy resources must be re-evaluated.

    The genetic profile based on autosomal markers, four microsatellite DNA markers (D8S315, FES, D8S592, and D2S1328) and two minisatellite DNA markers (TPMT and PDGFA), were analyzed in six endogamous populations to examine the effect of geographic and linguistic affiliation on the genetic affinities among the groups. The six populations are from three different states of India and are linguistically different. Marathas from western India speak Marathi, an Indo-European language. Arayas, Muslims, Ezhavas, and Nairs from Kerala state of South India speak Malayalam, and Iyers from Tamil Nadu state speak Tamil. Genomic DNA was extracted from peripheral blood samples of random, normal, healthy individuals. Locus-specific PCR amplification was carried out, followed by electrophoresis of the amplicons and genotyping. All the loci were highly polymorphic and followed Hardy-Weinberg equilibrium, except for loci D8S315 and PDGFA in Iyers and Marathas, respectively. All six loci had high heterozygosity (average heterozygosity ranged from 0.73 to 0.76) and high polymorphism information content (0.57-0.90). The extent of gene differentiation among the six populations (G(ST) = 0.030) was greater than that for four Kerala populations (G(ST) = 0.011), suggesting proximity between the four Kerala populations. This result conforms with the cultural and linguistic background of the populations. The extent of diversity found among the populations probably resulted from the strict endogamous practices that they follow.

  4. Earthquake Hazard and Risk Assessment Based on Unified Scaling Law for Earthquakes: State of Gujarat, India

    The Gujarat state of India is one of the most seismically active intercontinental regions of the world. Historically, it has experienced many damaging earthquakes including the devastating 1819 Rann of Kachchh and 2001 Bhuj earthquakes. The effect of the later one is grossly underestimated by the Global Seismic Hazard Assessment Program (GSHAP). To assess a more adequate earthquake hazard for the state of Gujarat, we apply Unified Scaling Law for Earthquakes (USLE), which generalizes the Gutenberg-Richter recurrence relation taking into account naturally fractal distribution of earthquake loci. USLE has evident implications since any estimate of seismic hazard depends on the size of the territory considered and, therefore, may differ dramatically from the actual one when scaled down to the proportion of the area of interest (e.g. of a city) from the enveloping area of investigation. We cross-compare the seismic hazard maps compiled for the same standard regular grid 0.2° × 0.2° (1) in terms of design ground acceleration based on the neo-deterministic approach, (2) in terms of probabilistic exceedance of peak ground acceleration by GSHAP, and (3) the one resulted from the USLE application. Finally, we present the maps of seismic risks for the state of Gujarat integrating the obtained seismic hazard, population density based on India's Census 2011 data, and a few model assumptions of vulnerability.

    In India, power generation and distribution is the responsibility of the different States that have their own electricity boards through which this is done. Of late, in the wake of liberalization, many attempts have been made to reform the power sector, in the light of the poor performance of these boards. The Haryana State Electricity Board (HSEB) is the primary supplier of power in one of the States called Haryana. For quite some years, it was facing problems with revenues, low PLF etc. A review was done and counselling help sought from prominent Consultancy firms. As a result a large scale restructuring was planned. The present paper looks at the attempts of HSEB at restructuring and the consequences of the restructuring efforts. (authors)

    2014-06-01

    Full Text Available Objectives: In India, gender inequality in nutrition, from infancy to adulthood, is a common phenomenon. Women never reach their full growth potential due to nutritional deficiency. Height and weight reflects nutritional deficiency. Knowledge of inter-state variations in adult height and weight can help us to explain the differences due to socio-cultural and economic factors like poverty, illiteracy, cultural barriers, concentration of multiple ethnicity, physical geography etc. The main objective of this study is to see the variation of adult height, weight and BMI along with gender differences in the states of India. Methods: This study is based on a sample of 64984 male and 118781 female of 15-49 age groups. Data are obtained from the National Family Health Survey, 3rd round (NFHS-3 conducted by International Institute of Population Sciences (IIPS, during the period of 2005 to 2006. Descriptive studies and logistic regression analyses were conducted to examine the variations in the difference of height, weight and BMI of adult male and female in India. Results: There is a clear positive relation of height with the economic level reflected through wealth index. Education level also has strong positive effect on height. It is found in this study that mean male height is the highest in north zone followed by west and south zone. The lowest mean height is seen in north east zone. Similar results in case of mean weight are also found in those zones but in case of mean BMI south zone show the highest position where east and central zones follow. The intensity of mean height, weight and BMI for adult females varies more than that of males but the variation pattern is similar for both males and females. Conclusions: Socio-cultural differences including differences in economic pattern may be the leading causes in the variation of height weight distribution in the states of India. In this context, level of living and education need to be given proper

    Full Text Available Abstract Background Increasingly, women in India attend health facilities for childbirth, partly due to incentives paid under government programs. Increased use of health facilities can alleviate the risks of infections contracted in unhygienic home deliveries, but poor infection control practices in labour and delivery units also cause puerperal sepsis and other infections of childbirth. A needs assessment was conducted to provide information on procedures and practices related to infection control in labour and delivery units in Gujarat state, India. Methods Twenty health care facilities, including private and public primary health centres and referral hospitals, were sampled from two districts in Gujarat state, India. Three pre-tested tools for interviewing and for observation were used. Data collection was based on existing infection control guidelines for clean practices, clean equipment, clean environment and availability of diagnostics and treatment. The study was carried out from April to May 2009. Results Seventy percent of respondents said that standard infection control procedures were followed, but a written procedure was only available in 5% of facilities. Alcohol rubs were not used for hand cleaning and surgical gloves were reused in over 70% of facilities, especially for vaginal examinations in the labour room. Most types of equipment and supplies were available but a third of facilities did not have wash basins with "hands-free" taps. Only 15% of facilities reported that wiping of surfaces was done immediately after each delivery in labour rooms. Blood culture services were available in 25% of facilities and antibiotics are widely given to women after normal delivery. A few facilities had data on infections and reported rates of 3% to 5%. Conclusions This study of current infection control procedures and practices during labour and delivery in health facilities in Gujarat revealed a need for improved information systems

    Assessment of soil erosion risks, especially in the developing countries, is a challenging task mainly due to non-availability or insufficiency of relevant data. In this paper, the soil erosion risks have been estimated by integrating the spatial data on potential erosion rates and soil loss tolerance limits for conservation planning at state level in India. The erosion risk classes have been prioritized based upon the difference between the prevailing erosion rates and the permissible erosion limits. The analysis revealed that about 50% of total geographical area (TGA) of India, falling in five priority erosion risk classes, requires different intensity of conservation measures though about 91% area suffers from potential erosion rates varying from 40 t ha(-1) yr(-1). Statewise analysis indicated that Andhra Pradesh, Maharashtra and Rajasthan share about 75% of total area under priority Class 1 (6.4 M ha) though they account for only 19.4% of the total area (36.2 M ha) under very severe potential erosion rate category (> 40 t ha(-1)yr(-1)). It was observed that about 75% of total geographical area (TGA) in the states of Bihar, Gujarat, Haryana, Kerala and Punjab does not require any specific soil conservation measure as the potential erosion rates are well within the tolerance limits. The developed methodology can be successfully employed for prioritization of erosion risk areas at watershed, region or country level.

    Implant treatment today is highly reliable as a valid restorative option for missing teeth. As more patients worldwide opt for implant treatment, it is now imperative for dental practitioners to have sound information about dental implants so they can help patients make informed decisions. This study sought to define the knowledge and attitudes regarding dental implants of dental interns in the state of Karnataka, India, and to evaluate the dental implant curriculum structure at the undergraduate level. A survey was conducted of dental interns (students in their fifth, clinical year of undergraduate study) in seven of the forty-five academic dental institutions in this state. The questionnaire consisted of fifteen questions that assessed the respondents' level of knowledge and source of information regarding implants. A total of 500 questionnaires were distributed, and 417 interns responded for a response rate of 83.4 percent. In the results, 73.3 percent reported they were not provided sufficient information about implants in their undergraduate curriculum, and 95.7 percent of them wanted more. Also, 63.5 percent of the respondents believed that high costs could limit the use of dental implants as a tooth replacement modality in India. This study concludes that revision in the undergraduate dental curricula at these schools is needed to better prepare students for practicing implant dentistry.

    Full Text Available Dengue has been reported from plains as well as hilly regions of India including some parts of Northeast India. In July-August 2012, outbreak of fever with unknown origin (FUO indicative of Dengue was reported in Pasighat, East Siang district of Arunachal Pradesh (AP state. Serum samples (n = 164 collected from patients from Health Training and Research Centre General Hospital, Pasighat, were tested for NS1 antigen and IgM antibodies. NS1-positive samples were analyzed by RT-PCR assay and entomological surveys were carried out. The majority of suspected cases reported NS1 antigen positivity. Females and young adults were mostly affected. The majority of the amplified NS1-positive samples showed Dengue serotype 3 infection. Aedes (Stegomyia albopictus, known as semiurban breeding mosquitoes, was the only potential vector species identified from the affected areas of Pasighat which single handedly contributed to the outbreak. Thus, the present work identifies Dengue as an emerging arboviral infection in hilly state of AP along with a looming risk of its spread to neighbouring areas.

    The present communication records the first determination of the prevalence of footrot in the unexpected situation of the tropical climate of Andhra Pradesh and Tamil Nadu, two states in southern India where the maximum temperature rises to 42 degrees C. In total, 73 outbreaks of footrot in Nellore brown sheep were investigated in 11 districts of Andhra Pradesh and one district of Tamil Nadu during the period March 2009 to March 2011.The overall prevalence of ovine footrot was 15%, with severity scores of 2 to 4 (lesion severity scale 0 to 4). The outbreaks occurred mostly during the rainy season, which is usually from June to December. From a total of 1,050 samples of lesions in naturally infected sheep, 478 (45.5%) were positive for Dichelobacter nodosus. Serogrouping of the isolates revealed six serogroups: A, B, C, E, F and I. Among the positive samples, 448 (93.7%) were a single serogroup and 30 (6.3%) carried a mixed infection with two serogroups. Taking single and mixed infections together, serogroup B was most frequent at 50.4% and was found in all districts, followed by serogroup I in 29.3% of samples, A in 14%, F in 6.7% and C in 5.6%. Serogroup E was detected in only one sample. Serogroups A and F were detected for the first time in India. All of 58 D. nodosus isolates in a sub-sample representing different serogroups were found to be virulent, based on the production of thermostable proteases and the presence of the integrase A gene intA. Thus, the present paper reporting isolation and characterisation of D. nodosus confirms the occurrence of virulent footrot in the tropical climate of southern India.

    Chronic illnesses are an increasing cause of morbidity and mortality in rural India. Many patients default from treatment, and exploring their reasons for the same may suggest strategies to improve service accessibility and acceptability. A qualitative study was conducted of 22 patient interviews, six key informant interviews, and two patient focus group discussions for investigating the reasons for default at the KC Patty Primary Health Centre and surrounding villages in Kodaikanal Taluk, Dindigul district, Tamil Nadu. The reasons included money or transport difficulties, frequent travel, feeling healthy, focus on work, fear of scolding from clinic staff, medication side effects, preference for alternative therapy, and depression. Some reasons were only divulged after an extended discussion. Support from families and village-level health workers (VLHWs) were also identified as important. Recommendations include more open and patient communication between health workers and defaulting patients, in addition to recruitment of more VLHWs.

    Full Text Available Background: Tamil Nadu comes under group I high-prevalence state, with <1% prevalence of HIV infection in ante-natal women but above 5% prevalence in high-risk group. One of the ways to control HIV/AIDS in India is through prevention of parent to child transmission (PPTCT, the success of which lies in the utilization of services. Materials and Methods: A descriptive qualitative study was conducted to explore the status of utilization of PPTCT services by rural HIV-positive mothers, in the Gingee Block of Villupuram district, Tamil Nadu. All the mothers who tested positive between June 2006 and May 2010 were interviewed in-depth using an interview guide. Results: There were 21 HIV-positive mothers during this period, 19 of whom gave consent for the study. Thirteen out of 19 mothers (68% received Nevirapine prophylaxis, while 15 out of 20 infants born to these mothers (75% received Nevirapine syrup. During the study period, it was found that 61% of the mothers were not compliant to antiretroviral therapy (ART. Conclusion: Poor access to the ART centers was reflected in majority of the cases (79%. There is a pressing need to improve access to quality PPTCT services especially during the intranatal period.

We obtained output and economic cost data for the 2005-2006 fiscal year from a representative sample of 128 public-funded HIV prevention programmes of 14 types in Andhra Pradesh state of India. Using data from various sources, we developed a model to estimate the number of HIV infections averted. We estimated the additional HIV infections that could be averted if each intervention reached optimal coverage and the associated cost. In a year, 9688 HIV infections were averted by public-funded HIV prevention interventions in Andhra Pradesh. Scaling-up interventions to the optimal level would require US$38.8 million annually, 2.8 times the US$13.8 million economic cost in 2005-2006. This could increase the number of HIV infections averted by 2.4-fold, if with higher resources there were many-fold increases in the proportional allocation for programmes for migrant labourers, men who have sex with men and voluntary counselling and testing, and reduction of the high proportion for mass media campaigns to one-third of the 2005-2006 proportion of resource utilization. If the proportions of resource allocation for interventions remained similar to 2005-2006, the higher resources would avert 54% of the additional avertable HIV infections. The recent four-fold increase in public funding for HIV/AIDS control in India should be adequate to scale-up HIV prevention interventions to an optimal level in Andhra Pradesh, but the prevention would be suboptimal if additional investments were not preferentially directed to some particular interventions.

  2. (PostColonial State and Constitutionalism in India. Differences and Crossings

    Full Text Available The article argues that the end of the formal division of the world between a colonizing metropolis and a colonized periphery requires a different reading of the State’s history. The essay deals with the relation between the formation of British India and the development of Indian nationalist movement through the events related to the ‘tiger of Mysore’, Tipu Sultan, and the swadeshi movement as portrayed in Tagore’s The Home and the World. The essay shows how colonial constitutionalism developed through the contemporary affirmation of the rule of law and the colonial difference. The postcolonial State emerged via concrete crossing of this difference, which today allows a different reading of the political discourses beyond the affirmation of the State as the barycenter of political organization at a global scale.

    Full Text Available Abstract Background Oral health status in India is traditionally evaluated using clinical indices. There is growing interest to know how subjective measures relate to outcomes of oral health. The aims of the study were to assess the prevalence and correlates of self-reported state of teeth in 12-year-old schoolchildren in Kerala, India. Methods Cross-sectional survey data were used. The sample consisted of 838 12-year-old schoolchildren. Data was collected using clinical examination and questionnaire. The clinical oral health status was recorded using Decayed, Missing and Filled Teeth (DMFT and Oral Hygiene Index – Simplified (OHI-S. The questionnaire included questions on sociodemographics, self reports of behaviour, knowledge and oral problems and a single-item measuring self-reported state and satisfaction with appearance of teeth. The Kappa values for test-retest of the questionnaire ranged from 0.55 to 0.97. Results Twenty-three per cent of the schoolchildren reported the state of teeth as bad. Multivariate logistic regression showed significant associations between schoolchildren who reported to have bad teeth and poor school performance (Odds Ratio (OR = 2.5, having bad breath (OR = 2.4, food impaction (OR = 1.7 dental visits (OR = 1.6, being dissatisfied with appearance of teeth (OR = 4.2 and caries experience (OR = 1.7. The explained variance was highest when the variables dental visits, bleeding gums, bad breath, food impaction and satisfaction with appearance were introduced into the model (19%. Conclusion A quarter of 12-year-olds reported having bad teeth. The self-reported bad state of teeth was associated with poor school performance, having bad breath and food impaction, having visited a dentist, being dissatisfied with teeth appearance and having caries experience. Information from self-reports of children might help in planning effective strategies to promote oral health.

    Most low- and middle-income countries (LMICs) have struggled to find a system for prehospital care that can provide adequate patient care and geographical coverage while maintaining a feasible price tag. The emergency medical systems of the Western world are not necessarily relevant in developing economic systems, given the lack of strict legislation, the scarcity of resources, and the limited number of trained personnel. Meanwhile, most efforts to provide prehospital care in India have taken the form of adapting Western models to the Indian context with limited success. Described here is a novel approach to prehospital care designed for and implemented in the State of Kerala, India. The Active Network Group of Emergency Life Savers (ANGELS) was launched in 2011 in Calicut City, the third largest city in the Indian State of Kerala. The ANGELS integrated an existing fleet of private and state-owned ambulances into a single network utilizing Global Positioning System (GPS) technology and a single statewide call number. A total of 85 volunteer emergency medical certified technicians (EMCTs) were trained in basic first aid and trauma care principles. Public awareness campaigns accompanied all activities to raise awareness amongst community members. Funding was provided via public-private partnership, aimed to minimize costs to patients for service utilization. Over a two-year period from March 2011 to April 2013, 8,336 calls were recorded, of which 54.8% (4,569) were converted into actual ambulance run sheets. The majority of calls were for medical emergencies and most patients were transported to Medical College Hospital in Calicut. This unique public-private partnership has been responsive to the needs of the population while sustaining low operational costs. This system may provide a relevant template for Emergency Medical Services (EMS) development in other resource-limited settings. Brown HA , Douglass KA , Ejas S , Poovathumparambil V .

    The importance of the mobile phone is evidenced by predictions that there will be 1.76 billion smartphone users worldwide at the start of 2015. A country that is spearheading this movement toward the digital era is India. To illustrate this, India is expected to surpass the United States in 2015 and record the second highest smartphone sales globally. Despite the rising penetration and adoption of smartphones, there is limited advertising research that sheds light on the Indian smartphone user. The current study aims to fill that void by cross-culturally comparing a national online panel of smartphone users from India (n=158) with users from the United States (n=114). Findings reveal that entertainment impacts Indians' attitudes toward smartphone advertising while informativeness is stronger for the American sample. Collectivism was found to be the driving force behind socializing activities on social networking sites for Indian consumers. Implications are discussed.

    Full Text Available The pneumococcal conjugate vaccine (PCV is not available through universal immunization programs but is available through private healthcare providers. Because the PCV coverage rates are unknown, we developed a Microsoft Excel-based coverage assessment model to estimate state-specific PCV coverage for the year 2012. Our findings suggest that in the private sector, the "overall PCV coverage" was around 0.33% that ranged between a minimum of 0.07% for Assam, India and a maximum of 2.38% for Delhi, India. Further, in major metropolitan areas, overall PCV coverage rates were: 2.28% for Delhi, India, 13.31% for Mumbai (Maharashtra, India 0.76% for Lucknow (Uttar Pradesh, India, 1.93% for Kolkata (West Bengal, India, and 4.92% for Chennai (Tamil Nadu, India highlighting that urban centers are major drivers for PCV utilization driver in the states with high PCV consumption. Hence, to improve PCV coverage, both demand side (increasing consumer awareness about pneumonia prevention and supply side (controlling vaccine prices and indigenous vaccine production interventions are required.

    Full Text Available General strike (also known as hartal is used as a mode of protest by organizations and political parties in India. It is generally thought that hartals negatively impact the healthcare delivery in a society. We used the Right to Information Act to obtain data from government health centers in Kerala state in India for four hartal days (H-day and two control days (A-day and B-day for each H-day, from sixteen health centers including 6 Community Health Center (CHC, 6 Secondary Health Center (SHC, and 4 Tertiary Health Center (THC. Data on emergency room visits was available for six HCs. 15 HCs had a statistically significant decrease in the number of outpatient visits on H-day. There was no difference in the number of outpatient visits between the two control days (A and B in 15 HCs, suggesting the lack of a posthartal surge in visits. Median decrease in outpatient visits in CHCs, SHCs, and THCs was 50.4%, 59.5%, and 47.4%, respectively. Hartal did not impact the number of emergency room visits in 6 out of 7 health centers assessed. Our study identified a significant harmful impact on government healthcare delivery due to hartals in Kerala. These findings have major public health implications.

    Radiographs are used extensively in dentistry to supplement the clinical examination of the patients. Technical advances in X-ray equipment and imaging systems have allowed significant reduction in radiation doses of patients during intraoral and extraoral radiography. The aim of this study was to determine the level of awareness of dental professionals of northern India regarding dose-reduction techniques and radiographic equipment. The survey covered 370 dentists in the states of Punjab and Haryana in northern India. Information on the demographic characteristics of the dentists, radiographic equipment, techniques, and radiation protection was obtained with a 30-point questionnaire. The respondents knowledge concerning the technical details of their equipment was limited, with 82.3% not being aware about the kilovoltage peak of their machine. Up to 10.8% dentists were not aware about the speed of film. The most preferred technique for periapical radiography was the bisecting angle technique, which was used by 94.1% dentists. In the present study the results indicate that for minimizing any unnecessary radiation, attempts should be made to improve dentists' knowledge about radiation-dose-reduction techniques. © 2012 Wiley Publishing Asia Pty Ltd.

This paper places the bio-genetic industry within the larger political economy framework of globalisation and privatisation, thus employing a framework that is often omitted from discussions on ARTs, but has direct and significant bearings on the ART industry in India. As markets for human organs, tissues and reproductive body parts experience unprecedented growth, the limits of what can or should be bought and sold continue to be pushed. As such, bodies have emerged as sale-worthy economic capital. Commercial flows of reproductive material create and deploy the division of the body into parts over which ownership is claimed, in the process following 'modern routes of capital' and raising issues of structural inequality. This paper presents a brief picture of India's fertility industry with specific focus on its ground-level operation, nature and growth. It aims to explore the industry dimensions of ARTs, by highlighting the macro picture of health care markets and medical tourism in India, the proliferation of the ART industry, market features such as the social imperative to mother, costs, promotion and marketing, unverified claims, inflated success rates, deals and offers, actors and collaborations in the field, and finally, the absence of standards.

  11. Choosing to comply with the U.S.-India civil nuclear agreement. Factors leading to state compliance

    Full Text Available State compliance with international commitments is uneven. However, the perception of which countries will and will not comply and to what extent can be biased. Some scholars assume that the U.S. will abide by the India-U.S. 123 civil nuclear agreement, which main objective is to supply India with nuclear fuel. At the same time, some other researchers doubt that India would honor its respective commitments, namely, to maintain safeguard measures in its nuclear facilities. The present study expands the knowledge of the factors affecting compliance within the realm of nuclear trade by analyzing a non-binding instrument negotiated between two asymmetrical actors. Drawing on Peter Haas’ compliance theories, the author analyzes the incidence as well as the relevance of international institutional and ideational factors which, in combination with domestic politics and structures, can influence the actor’s decision to comply. The paper’s findings suggest that India can be expected to more fully comply with the provisions of the treaty than the United States. Depending on whether certain institutional or ideational factor intervenes, Washington is either not capable or is not willing to comply. Its will to comply could be affected, inter alia, by important domestic actors concerned with the application of the Hyde Act, as evidenced during the ratification process. Therefore, contrary to the mainstream view, the 123 Agreement neither enables India to achieve energy security nor ends thirty-four years of nuclear isolation.

We aimed to bridge this gap by inductively deriving potential universal dimensions of spirituality through a large-scale, multi-national data collection and examining the relationships of these dimensions with common psychiatric conditions. Five-thousand five-hundred twelve participants from China, India, and the United States completed a two-hour online survey consisting of wide-ranging measures of the lived experience of spirituality, as well as clinical assessments. A series of inductive Exploratory Factor Analysis (EFA and cross-validating Exploratory Structural Equation Modeling (ESEM were conducted to derive common underlying dimensions of spirituality. Logistic regression analyses were then conducted with each dimension to predict depression, suicidal ideation, generalized anxiety, and substance-related disorders. Preliminary EFA results were consistently supported by ESEM findings. Analyses of forty spirituality measures revealed five invariant factors across countries which were interpreted as five dimensions of universal spiritual experience, specifically: love, in the fabric of relationships and as a sacred reality; unifying interconnectedness, as a sense of energetic oneness with other beings in the universe; altruism, as a commitment beyond the self with care and service; contemplative practice, such as meditation, prayer, yoga, or qigong; and religious and spiritual reflection and commitment, as a life well-examined.

    The future economic development trajectory for India is likely to result in rapid and accelerated growth in energy demand, with expected shortages. Many of its current policies and strategies are aimed at the improvement and possible maximization of energy production from the renewable sector. It is also clear that while energy-conservation and energy-efficiency can make an important contribution in the national energy strategy, renewable energies will be essential to the solution and are likely to play an increasingly important role for the growth of grid power, providing energy access, reducing consumption of fossil fuels, and helping India pursue its low carbon progressive pathway. However, most of the states in India, like the northernmost State of Jammu and Kashmir (J and K), have experienced an energy crisis over a sustained period of time. As India intends to be one of the emerging powers of the 21st century, it has to embark upon with these pressing issues in a more sustainable manner and accordingly initiate various renewable energy projects within these states. This paper will provide a broad-spectrum view about the energy situation within J and K and will highlight the current policies along with future strategies for the optimal utilization of renewable energy resources. - Highlights: > To present an overview of the current energy situation in the State of Jammu and Kashmir, India. > To analyze the potential of the various renewable energy resources available in the State given the existing constraints. > To state the challenges of the administration to incentivize the participation of private initiative in energy development.

    In this article we examine factors associated with women's self-reports of reproductive ill health symptoms and factors associated with seeking and receiving treatment for the symptoms. We focus on indicators of women's societal position, especially empowerment (indicated by experience of and attitudes toward violence against women), autonomy, and education. We used data from the National Family Health Survey-2 from Kerala state in Southern India. Based on our results we suggest that violence against women, whether actually experienced or internalized as acceptance of its justification, is associated with increased ill health symptoms, and the acceptance of violence is associated with decreased chance of treatment. Women's higher formal education appeared to reduce treatment seeking for reproductive ill health, perhaps due to the stigma associated with sexually transmitted disease (STD) in this cultural setting. Women's work participation had no significant impact, nor did indicators of women's economic and personal autonomy.

We constructed a computer simulation model to determine the potential economic value of a VL vaccine in the endemic region of Bihar state, India. Results found a potential vaccine to be cost-effective (and in many cases economically dominant, i.e., saving costs and providing health benefits) throughout a wide range of vaccination costs and vaccine efficacies, and VL risks. Overall, our study strongly supports the continued development of a VL vaccine.

    A study on the native uses of ethnobotanical species was carried out in the south Surguja district of Chhattisgarh state in India with the major objective of identifying different food and medicinal plant species and also to understand their ongoing management and conservation. Through questionnaire and personal interviews, a total of 73 ethnobotanical species used by tribal and non-tribal communities were documented, of these 36 species were used in curing different types of diseases and 22 were used as edible food plants. This rich traditional knowledge of local people has an immense potential for pharmacological studies. The outside forces, at present, were mainly blamed to change the traditional system of harvesting and management of ethnobotanical species. The destructive harvesting practices have damaged the existing populations of many ethnobotanical species viz., Asparagus racemosus, Dioscorea bulbifera, Boswellia serrata, Buchnania lanzan, Sterculia urens and Anogeissus latifolia. The sustainable harvesting and management issues of ethnobotanical species are discussed in view of their conservation and management.

    Public engagement through government-sponsored "public consultations" in biomedical innovation, specifically stem cell research and therapy, has been relatively limited in India. However, patient groups are drawing upon collaborations with medical practitioners to gain leverage in promoting biomedical research and the conditions under which patients can access experimental treatments. Based on qualitative fieldwork conducted between 2012 and 2015, I examine the ways in which two patient groups engaged with debates around how experimental stem cell therapy should be regulated, given the current lack of legally binding research guidelines. Such processes of engagement can be seen as an alternative form of biomedical governance which responds to the priorities and exigencies of Indian patients, contrasting with the current measures taken by the Indian state which, instead, are primarily directed at the global scientific and corporate world.

  6. Four TDR diseases can be "eliminated". 1. India's bold new plans for filariasis control.

    1996-03-01

    India has 38% of the world's cases of bancroftian lymphatic filariasis and 20% of all cases of brugian lymphatic filariasis. One of India's major public health problems, filariasis is endemic in 18 states of the country, but absent in the northeast and northwest regions. The National Filaria Control Program (NFCP) was launched in 1955, but now covers only 46 million people, using a 12-day DEC treatment. In its 1995 draft, India's revised strategy for controlling filariasis in the country calls for the supply of 200 million 50 mg DEC tablets by May 1996, to be distributed in target villages on a newly designated National Filariasis Day (NFD), August 5, 1996, at the beginning of the school year. The day should be widely publicized by the mass media, nongovernmental organizations, and health authorities. The 1996 effort in two selected districts of Andrha Pradesh, Kerala, Orissa, Tamil Nadu, Uttar Pradesh, West Bengal, and Bihar will be followed on the same date in successive years, each year covering more affected areas, and aiming to cover all affected areas by the third year.

The Hindu temples of Lord Sri Laxminarasimha Swamy and Lord Hanuman, and the ethnic worship of mahua trees indicated it was a sacred grove which was selected as a Medicinal Plants Conservation Area. The exploration of Mallur Gutta resulted in the enumeration and documentation of plant wealth representing 470 species of 318 genera pertaining to 95 families of vascular plants. The importance of the grove as the residence for many rare or medicinal species in the state of Telangana is documented. The plant diversity is analyzed in terms of growth and life forms which indicate the prevailing microclimate, ecological opportunities and the species richness. The ecological services rendered by the Mallur Gutta forest ecosystem are documented to study how the great majority of the species are used by the ethnic and nonethnic people, and also the pilgrims who visit the shrine for its serenity. The study also identified two major threats to the conservation of hill ecosystem and the archeological site: 1 biotic pressure (the ever-increasing pilgrims, grazing by cattle, goat and sheep, the development activities taken up for the pilgrims, nondegradable litter thrown, collection of medicinal plants and widening of the pathway to the Chintamani perennial stream – the trampling and alien plant invasions of the marsh sustaining the stream; and 2 the potential for fire spreading from burning the litter. The study suggests the need to initiate remedial measures toward ecosystem

    Full Text Available Abstract Background Information on cost-effectiveness of the range of HIV prevention interventions is a useful contributor to decisions on the best use of resources to prevent HIV. We conducted this assessment for the state of Andhra Pradesh that has the highest HIV burden in India. Methods Based on data from a representative sample of 128 public-funded HIV prevention programs of 14 types in Andhra Pradesh, we have recently reported the number of HIV infections averted by each type of HIV prevention intervention and their cost. Using estimates of the age of onset of HIV infection, we used standard methods to calculate the cost per Disability Adjusted Life Year (DALY saved as a measure of cost-effectiveness of each type of HIV prevention intervention. Results The point estimates of the cost per DALY saved were less than US $50 for blood banks, men who have sex with men programmes, voluntary counselling and testing centres, prevention of parent to child transmission clinics, sexually transmitted infection clinics, and women sex worker programmes; between US $50 and 100 for truckers and migrant labourer programmes; more than US $100 and up to US $410 for composite, street children, condom promotion, prisoners and workplace programmes and mass media campaign for the general public. The uncertainty range around these estimates was very wide for several interventions, with the ratio of the high to the low estimates infinite for five interventions. Conclusions The point estimates for the cost per DALY saved from the averted HIV infections for all interventions was much lower than the per capita gross domestic product in this Indian state. While these indicative cost-effectiveness estimates can inform HIV control planning currently, the wide uncertainty range around estimates for several interventions suggest the need for more firm data for estimating cost-effectiveness of HIV prevention interventions in India.

    Full Text Available We investigated the human–wild pig conflict in 5 different states in India. In these states,the wild pig populations are fragmented and relatively isolated all over. Agricultural crop depredation andattacks on humans being by wild pigs is a major problem. During 1990-2008, a total 309 human killingand injury cases were caused by wild pigs in these states. There was marked monthly variation inhuman casualties. Highest number of casualties occurred in November (n = 61. Wild pigs causedmaximum human casualties in forests (73.8% than crop fields (21.7% and villages (4.5%. Highestnumber of 92 human casualties occurred in the age group of 41-50 years. Highest number of 97 humancasualties occurred between 0801-1200 h (n = 97. Damage to agricultural crops by wild pigs was ofvarying extent (5-36%. As a result, people have developed antagonistic attitude towards the wild pigswhich adversely affect the conservation efforts. Recommendations have been made for reducing thehuman–wild pig conflict in these states.

    Foraminifera have been successful inhabitants of every aquatic environment from deep oceans to brackish water lagoons, estuaries and even rarely in freshwater streams, lakes etc. offshore region of Karaikal the present study has been taken up to enhance the existing knowledge on foraminifera of central coast of Tamil Nadu, India. Totally 21 sediment and water samples were collected from the offshore region. The depth of sample collection in offshore area ranges from 1.5 m to 12 m. Standard procedures adopted for the evaluation of different environmental parameters are incorporated. A total of 33 foraminiferal taxa belonging to 17 genera, 12 subfamilies, 14 superfamilies, and 4 suborders have been identified. In Karaikal , the mean size of the sediments on the foreshore ranges from 1.51 to 2.95 φ indicating the predominance of fine sediments (80-85%) with an admixture of medium-grained sands. Calcium carbonate content is generally found to be directly proportional to the population size in both the estuary and shelf area. It clearly indicates that due to the erosional activities whatever sediments deposited near the Arasalar river in that region are transported to the marine region and were drifted towards northern direction by longshore current, hence the deposition of carbonate in the sediments shows negative correlation. Due to strong high energy environment the current action is more in this region the juvinile forms of A. beccarri, A.tepida, A. dendata, E. crispum, P. calar, and P. nipponica only withstand and the other species are absent. The Correlation between Living vs Dead, Dead Vs Calcium carbonate, Salinity Vs living, Organic matter Vs Living, Organic matter Vs Carbonate content shows positive correlation for all the samples like LT, HT, Beach, River, and Offshore. Even though, all the ecological parameters having good correlation with foraminifera, but the distribution are very less in the study area. M.RAJA Dept.of.Geology University of Madras Chennai

    As one of the 17 megadiverse countries of the world and with four biodiversity hotspots represented in its borders, India is home to an impressive diversity of life forms. However, much work remains to document and catalogue the species of India and their geographic distributions, especially for diverse invertebrate groups. In the present study, a comprehensive and critical list of Indian ant species is provided with up-to-date state-wise distribution. A total of 828 valid species and subspecies names belonging to 100 genera are listed from India. Potential erroneous data, misidentifications and dubious distributional records that may exist in the literature are also identified. The present exhaustive listing of Indian ants will provide a holistic view about diversity and distribution and will also help to identify major undersampled areas where future sampling and taxonomic efforts should be directed.

    The National Programme for the Elimination of Lymphatic Filariasis is underway in the endemic districts of Tamil Nadu State, South India, since 2001. Annual mass drug administration (MDA) was carried out by the state health department to all eligible individuals. The impact of MDAs on transmission parameters was evaluated in 2 revenue blocks, viz, one with DEC alone and the other with a combination of albendazole. After 10 years with 6 annual MDAs, the transmission indices reached low levels in both treatment arms, but still persisted. However, the DEC alone arm showed higher transmission rates, compared to the DEC+ALB arm. Few villages which demonstrated persistent transmission need to be targeted with an additional control measure viz, vector control, to achieve LF elimination. It is evident from the 10 year period of the study that inclusion of albendazole along with DEC has significantly reduced the transmission indices to almost nil level, as compared to DEC alone.

    Full Text Available OBJECTIVES : To obtain baseline information about prevalence of tobacco use among school children in eight states in the North-eastern part of India. MATERIAL AND METHODS : A two-stage probability sample of students in grades 8-10 corresponding to 13 to 15 years of age was selected in each state and surveyed through an anonymous, self-administered questionnaire. RESULTS : Among the sampled schools, the school response rate was 100% in all states except Tripura (92% and Meghalaya (96%. Among the eligible students, over 80% participated in the survey. Among the respondents, the proportion of boys ranged between 50% to 55%. Ever tobacco users ranged from 75.3% (Mizoram to 40.1% (Assam. Over 65% of users reported initiation at 10 years of age or earlier in all states except Mizoram (23.1%. The range of current tobacco use (any product was 63% (Nagaland to 36.1% (Assam. Current smokeless tobacco use ranged from 49.9% (Nagaland to 25.3% (Assam. Mizoram reported the highest current smoking (34.5%, mainly cigarette and Assam reported the lowest (19.7%, again mainly cigarette. Current smoking among girls (8.3% to 28.2% was also quite high. Over half of current cigarette smokers (53.2% to 96.3% and a high proportion of current smokeless tobacco users (38.5% to 80.8% reported feeling like having tobacco first thing in the morning. Only about 20% of students reported having been taught in school about the dangers of tobacco use, except in Mizoram (around 50%. Tobacco use by parents and close friends was positively associated with students′ current tobacco use. CONCLUSIONS : Tobacco use including smoking was very high, even among girls, in all eight states in the North-eastern part of India. Signs of tobacco dependency were already visible in these students, more among those who smoked. In general schools did not educate students about the hazards of tobacco use.

    2017-02-20

    This study aimed to identify the determinants of nutritional status of children in India with a special focus on dietary diversity at the state level. Household-level consumption data from three rounds of the Consumer Expenditure Survey of the National Sample Survey Organization (1993-2012) were used. Information on the nutritional status of children was taken from the National Family Health Survey (2005-06). Dietary diversity indices were constructed at the state level to examine diversity in quantity of food consumed and food expenditure. Multilevel regression analysis was applied to examine the association of state-level dietary diversity and other socioeconomic factors with the nutritional status of children. It was observed that significant variation in childhood stunting, wasting and underweight could be explained by community- and state-level factors. The results indicate that dietary diversity has increased in India over time, and that dietary diversity at the state level is significantly associated with the nutritional status of children. Moreover, percentage of households with a regular salaried income in a state, percentage of educated mothers and mothers receiving antenatal care in a community are important factors for improving the nutritional status of children. Diversity in complementary child feeding is another significant determinant of nutritional status of children. The study thus concludes that increasing dietary diversity at the state level is an effective measure to reduce childhood malnutrition in India.

    In 2009, after many delays and changes, India introduced a single pictorial health warning label (HWL) on smokeless tobacco (SLT) packing-a symbolic image of a scorpion covering 40% of the front surface. In 2011, the scorpion was replaced with 4 graphic images. This paper tested the effectiveness of SLT HWLs in India and whether the 2011 change from symbolic to graphic images increased their effectiveness. Data were from a cohort of 4733 adult SLT users (age15+) of the Tobacco Control Project (TCP) India Survey from 4 states. The surveys included key indicators of health warning effectiveness, including warning salience, and cognitive, emotional, and behavioral responses to the warnings. The HWL change from symbolic to graphic did not result in significant increases on any of the HWL outcome indicators. A substantial minority of SLT users were unaware that SLT packages contained HWLs (27% at both waves). Noticing the warnings was also remarkably low at both waves (W1 = 34.3%, W2 = 28.1%). These effects carried over to the cognitive and behavioural measures, where among those who noticed HWLs, about one-third reported forgoing SLT at least once because of the HWLs, and fewer than 20% reported that HWLs made them think about SLT risks or about quitting SLT. Even fewer reported avoiding HWLs (8.1 to 11.6%). Among those who quit using SLT by post-policy, awareness that SLT packaging contained HWLs was significantly greater at post-policy (86.8%) compared to pre-policy (77.8%, p = 0.02). Quitters were also significantly more aware of the post-policy HWLs compared to those who continued to use SLT (p India are low in effectiveness, and the change from the symbolic warning (pre-policy) to graphic HWLs (post-policy) did not lead to significant increases of effectiveness on any of the HWL indicators among those who continued to use SLT products, thus suggesting that changing an image alone is not enough to have an impact. There is a critical need to implement

    Uttarakhand State of India suffered a widespread devastation in June 2013 due to floods caused by excessive rain in the upper reaches of the Himalaya, glacial lake outburst flood (GLOF) and landslides. Restoration process in this mountainous State calls for scientifically sound planning so that the vulnerabilities and risks to such natural hazards are minimised and developmental processes are sustainable in long run. Towards this, an understanding of the patterns and major controls of damage of the recent disaster is a key requirement which can be achieved only if the primary data on locations and types of damage along with other local site conditions are available. Considering widespread damage, tough nature of terrain and the need for collecting the primary data on damage in shortest possible time, crowdsourcing approach was considered to be the most viable solution. Accordingly, a multiinstitutional initiative called "Map the Neighbourhood in Uttarakhand" (MANU) was conceptualised with the main objective of collecting primary data on damage through participation of local people (mainly students) using state-of-art tools and technologies of data collection and a mechanism to integrate the same with Bhuvan geo-portal (www.bhuvan.nrsc.gov.in) in near real-time. Geospatial analysis of crowd-sourced points with different themes has been carried out subsequently for providing inputs to restoration planning and for future developmental activities. The present paper highlights the capacity building aspect in enabling the data collection process using crowdsourcing technology.

    The goal of this study was to characterize the properties and duration of the foot-and-mouth disease (FMD) carrier state and associated serological responses subsequent to vaccination and naturally occurring infection at two farms in northern India. Despite previous vaccination of cattle in these herds, clinical signs of FMD occurred in October 2013 within a subset of animals at the farms containing juvenile-yearling heifers and steers (Farm A) and adult dairy cattle (Farm B). Subsequent to the outbreak, FMD virus (FMDV) asymptomatic carriers were identified in both herds by seroreactivity to FMDV non-structural proteins and detection of FMDV genomic RNA in oropharyngeal fluid. Carriers' seroreactivity and FMDV genome detection status were subsequently monitored monthly for 23 months. The mean extinction time of the carrier state was 13.1 ± 0.2 months, with extinction having occurred significantly faster amongst adult dairy cattle at Farm B compared to younger animals at Farm A. The rate of decrease in the proportion of carrier animals was calculated to be 0.07 per month. Seroprevalence against FMDV non-structural proteins decreased over the course of the study period, but was found to increase transiently following repeated vaccinations. These data provide novel insights into viral and host factors associated with the FMDV carrier state under natural conditions. The findings reported herein may be relevant to field veterinarians and governmental regulatory entities engaged in FMD response and control measures.

    Verma, Ramesh; Khanna, Pardeep

    2012-10-01

    Tetanus is caused by a neurotoxin produced by Clostridium tetani (C. tetani), a spore-forming bacterium. Infection begins when tetanus spores are introduced into damaged tissue. Tetanus is characterized by muscle rigidity and painful muscle spasms caused by tetanus toxin's blockade of inhibitory neurons that normally oppose and modulate the action of excitatory motor neurons. Maternal and neonatal tetanus (MNT) are caused by unhygienic methods of delivery, abortion, or umbilical-cord care. Maternal and neonatal tetanus are both forms of generalized tetanus and have similar clinical courses. About 90% of neonates with tetanus develop symptoms in the first 3-14 d of life, mostly on days 6-8, distinguishing neonatal tetanus from other causes of neonatal mortality which typically occur during the first two days of life. Overall case fatality rates for patients admitted to the hospital with neonatal tetanus in developing countries are 8-50%, while the fatality rate can be as high as 100% without hospital care. Tetanus toxoid (TT) vaccination of pregnant women to prevent neonatal tetanus was included in WHO's Expanded Program on Immunization (EPI) a few years after its inception in 1974. In 2000, WHO, UNICEF, and UNFPA formed a partnership to relaunch efforts toward this goal, adding the elimination of maternal tetanus as a program objective, and setting a new target date of 2005. By February 2007, 40 countries had implemented tetanus vaccination campaigns in high-risk areas, targeting more than 94 million women, and protecting more than 70 million subjects with at least two doses of TT. In 2011, 653 NT cases were reported in India compared with 9313 in 1990. As of February 2012, 25 countries and 15 States and Union Territories of India, all of Ethiopia except Somaliland, and almost 29 of 34 provinces in Indonesia have been validated to have eliminated MNT.

    A statewide survey of four endogamous Brahman populations of Tamil Nadu reveals a low level of inbreeding in three of them. In the fourth population, the Thengalai, the level is higher, but not as high as in other social castes. The Tamil Brahmans rank next to the Telugu and the Kanarese Brahmans in this respect. Uncle-niece marriages also occur as in Telugu-speaking populations, and these exceed in the two Ayyangar populations in comparison to the Ayyar. A decline of first-cousin marriages and an increase of uncle-niece marriages are detected in the first two living generations in each population.

  1. Implementation of Environmental Judgments in Context: A Comparative Analysis of Dahanu Thermal Power Plant Pollution Case in Maharashtra and Vellore Leather Industrial Pollution Case in Tamil Nadu

    2010-12-01

    Full Text Available This paper explores a relatively neglected aspect of understanding the post-environmental judgment scenario: the impact of environmental judgment at the grassroots level and why there has been variation in the implementation of environmental judgments. It examines two Supreme Court environmental judgments on industrial pollution in two different states of India-the Dahanu Power Plant Case in Thane District of Maharashtra and the leather industrial pollution case in Vellore District of Tamil Nadu-and raises one central question-what factors determine the effective implementation of Supreme Court’s environmental judgments. The premise of this paper is that, despite the existence of a well-established regulatory framework to enforce environmental laws and policies in India, there has been a variation in the implementation of environmental judgments. From the judicial activism perspective, emphasis is placed on how the nature and level of judicial intervention in the post-judgment scenario, ensures the effective implementation of its own directions. It is argued that judicial intervention in the implementation of its decisions has become crucial to enforce its directions, and that this intervention is undertaken not to take away the power and functions of implementing agency, but rather to translate its directions into action at the grassroots level. In turn, the successful enforcement of environmental judgments depends on the nature of judicial activism, or the way in which the judges bring changes in the implementation process. As a consequence, it is not the level of judicial activism in itself which is decisive, but the process of activism that contributes towards the effective implementation of its decisions. In establishing this argument, however, the paper also argues that the process of judicial activism in the implementation of its direction is triggered by the active and consistent involvement of civil-society groups at the grassroots

    Background Despite increasing importance being laid on use of routine data for decision making in India, it has frequently been reported to be riddled with problems. Evidence suggests lack of quality in the health management information system (HMIS), however there is no robust analysis to assess the extent of its inaccuracy. We aim to bridge this gap in evidence by assessing the extent of completeness and quality of HMIS in Haryana state of India. Methods Data on utilization of key maternal and child health (MCH) services were collected using a cross-sectional household survey from 4807 women in 209 Sub-Centre (SC) areas across all 21 districts of Haryana state. Information for same services was also recorded from HMIS records maintained by auxiliary nurse midwives (ANMs) at SCs to check under- or over-recording (Level 1 discordance). Data on utilisation of MCH services from SC ANM records, for a subset of the total women covered in the household survey, were also collected and compared with monthly reports submitted by ANMs to assess over-reporting while report preparation (Level 2 discordance) to paint the complete picture for quality and completeness of routine HMIS. Results Completeness of ANM records for various MCH services ranged from 73% for DPT1 vaccination dates to 94.6% for dates of delivery. Average completeness level for information recorded in HMIS was 88.5%. Extent of Level 1 discordance for iron-folic acid (IFA) supplementation, 3 or more ante-natal care (ANC) visits and 2 Tetanus toxoid (TT) injections was 41%, 16% and 2% respectively. In 48.2% cases, respondents from community as well as HMIS records reported at least one post-natal care (PNC) home visit by ANM. Extent of Level 2 discordance ranged from 1.6% to 6%. These figures were highest for number of women who completed IFA supplementation, contraceptive intra-uterine device insertion and provision of 2nd TT injection during ANC. Conclusions HMIS records for MCH services at sub-centre level

  3. The zone of social abandonment in cultural geography: on the street in the United States, inside the family in India.

    2012-09-01

    This essay examines the spaces across societies in which persons with severe mental illness lose meaningful social roles and are reduced to "bare life." Comparing ethnographic and interview data from the United States and India, we suggest that these processes of exclusion take place differently: on the street in the United States, and in the family household in India. We argue that cultural, historical, and economic factors determine which spaces become zones of social abandonment across societies. We compare strategies for managing and treating persons with psychosis across the United States and India, and demonstrate that the relative efficiency of state surveillance of populations and availability of public social and psychiatric services, the relative importance of family honor, the extent to which a culture of psychopharmaceutical use has penetrated social life, and other historical features, contribute to circumstances in which disordered Indian persons are more likely to be forcefully "hidden" in domestic space, whereas mentally ill persons in the United States are more likely to be expelled to the street. However, in all locations, social marginalization takes place by stripping away the subject's efficacy in social communication. That is, the socially "dead" lose communicative efficacy, a predicament, following Agamben, we describe as "bare voice."

This has been the major concern for the researchers, scientists and engineers for the last 50 years who actively involved in water quality modeling. Consequently, characterization of hydrodynamics and water budgets has been an essential component in the water-quality modeling. This paper presents on the simulation model for sediment transport, solids budget, bottom sediment as a distributed system under steady-state condition, and resuspension of solids due to currents etc. The solids considered for the study was mainly allochthonous as these are inorganic in nature and the rate of decomposition is negligible. The data collected refers to the part of the research work on Malaprabha River, near Belgaum - a district headquarters in the State of Karnataka, India. This river is a non-perennial one, and the flow is very less during the pre-monsoon period, which is favorable for application of these sediment models. The results obtained for the resuspension and burial velocities showed marked variations during the different seasons of the year. Resuspension velocities predominated during the monsoon period resulting in the nonsettlement of the solids and the burial velocity during the non-monsoon period. As the river receives raw sewage from an adjoining town - Khanapur, and also the agricultural discharges, it is worth to quantify the sediment deposition in the stream.

    To study the pattern and prevalence of dyslipidemia in a large representative sample of four selected regions in India. Phase I of the Indian Council of Medical Research-India Diabetes (ICMR-INDIAB) study was conducted in a representative population of three states of India [Tamil Nadu, Maharashtra and Jharkhand] and one Union Territory [Chandigarh], and covered a population of 213 million people using stratified multistage sampling design to recruit individuals ≥20 years of age. All the study subjects (n = 16,607) underwent anthropometric measurements and oral glucose tolerance tests were done using capillary blood (except in self-reported diabetes). In addition, in every 5th subject (n = 2042), a fasting venous sample was collected and assayed for lipids. Dyslipidemia was diagnosed using National Cholesterol Education Programme (NCEP) guidelines. Of the subjects studied, 13.9% had hypercholesterolemia, 29.5% had hypertriglyceridemia, 72.3% had low HDL-C, 11.8% had high LDL-C levels and 79% had abnormalities in one of the lipid parameters. Regional disparity exists with the highest rates of hypercholesterolemia observed in Tamilnadu (18.3%), highest rates of hypertriglyceridemia in Chandigarh (38.6%), highest rates of low HDL-C in Jharkhand (76.8%) and highest rates of high LDL-C in Tamilnadu (15.8%). Except for low HDL-C and in the state of Maharashtra, in all other states, urban residents had the highest prevalence of lipid abnormalities compared to rural residents. Low HDL-C was the most common lipid abnormality (72.3%) in all the four regions studied; in 44.9% of subjects, it was present as an isolated abnormality. Common significant risk factors for dyslipidemia included obesity, diabetes, and dysglycemia. The prevalence of dyslipidemia is very high in India, which calls for urgent lifestyle intervention strategies to prevent and manage this important cardiovascular risk factor.

    Full Text Available Abstract Background In the context of AVAHAN, the India AIDS Initiative of the Bill & Melinda Gates Foundation, general population surveys (GPS were carried out between 2006 and 2008 in Belgaum (northern, Bellary (mid-state and Mysore (southern districts of Karnataka state, south India. Data from these three surveys were analysed to understand heterogeneity in HIV risk. Methods Outcome variables were the prevalence of HIV and sexually transmitted infections (STIs. Independent variables included age, district, place of residence, along with socio-demographic, medical and behavioural characteristics. Multivariate logistic regression was undertaken to identify characteristics associated with HIV and differences between districts, incorporating survey statistics to consider weights and cluster effects. Results The participation rate was 79.0% for the interview and 72.5% for providing a blood or urine sample that was tested for HIV. Belgaum had the highest overall HIV (1.43% and Herpes simplex type-2 (HSV-2 (16.93% prevalence, and the lowest prevalence of curable STIs. In Belgaum, the HIV epidemic is predominantly rural, and among women. In Bellary, the epidemic is predominantly in urban areas and among men, and HIV prevalence was 1.18%. Mysore had the lowest prevalence of HIV (0.80% and HSV-2 (10.89% and the highest prevalence of curable STIs. Higher HIV prevalence among men was associated with increasing age (p25-29years=11.22,95%CI:1.42-88.74, AOR30-34years=13.13,95%CI:1.67-103.19 and AOR35-39years=11.33,95%CI:1.32-96.83, having more than one lifetime sexual partner (AOR=4.61,95%CI:1.26-16.91 and having ever used a condom (AOR=3.32,95%CI:1.38-7.99. Having a dissolved marriage (being widowed/divorced/separated was the strongest predictor (AOR=10.98,95%CI: 5.35-22.57 of HIV among women. Being a muslim woman was associated with lower HIV prevalence (AOR=0.27,95%CI:0.08-0.87. Conclusion The HIV epidemic in Karnataka shows considerable heterogeneity

    In India, the hypertensive disorders of pregnancy and postpartum haemorrhage are responsible for nearly 40 % of all maternal deaths. Most of these deaths occur in primary health settings which frequently lack essential equipment and medication, are understaffed, and have limited or no access to specialist care. Community health care workers are regarded as essential providers of basic maternity care; and the quality of care they provide is dependent on the level of knowledge and skills they possess. However, there is limited research regarding their ability to manage pregnancy complications. This study aims to describe the current state of knowledge regarding pre-eclampsia and eclampsia among community health care workers (auxiliary nurse midwives, accredited social health activists, staff nurses) in northern Karnataka, India. Furthermore, this study describes the treatment approaches used by various cadres of community health workers for these conditions. The findings of this study can help plan focussed training sessions to build upon their strengths and to address the identified gaps. Data were collected as part of a larger study aimed at assessing the feasibility of community-based treatment for pre-eclampsia. Eight focus group discussions were conducted in 2012-2013 in northern Karnataka State: four with staff nurses and auxiliary nurse midwives and four with accredited social health activists. In addition, twelve auxiliary nurse midwives and staff nurses completed questionnaires to explore their competence and self-efficacy in managing pre-eclampsia. Qualitative data were audio-recorded, transcribed verbatim and translated for thematic analysis using NVivo 10. Community health workers described their understanding of the origins of hypertension and seizures in pregnancy. Psychological explanations of hypertension were most commonly reported: stress, tension, and fear. The most common explanation for eclampsia was not receiving a tetanus vaccination. Despite

    Bluetongue (BT) and peste-des-petits-ruminants (PPR) are major transboundary diseases of small ruminant, which are endemic in India. Testing of bluetongue virus (BTV) and peste-des-petits-ruminants virus (PPRV) from recent outbreaks (2015-2016) in different regions of Haryana State of India revealed that 27.5% of the samples showed the presence of dual infection of BTV and PPRV. Analysis of Seg-2 of BTV (the serotype-determining protein) showed the presence of BTV-12w in several isolates. However, analysis of N gene fragment amplicons showed that viruses belong to lineage IV were most closely related to a pathogenic strain of PPRV from Delhi. This is the first report of co-circulation of PPRV lineage IV and bluetongue virus serotype 12 in the state. © 2017 Blackwell Verlag GmbH.

    This study examines the relationship between male to female physical domestic violence and contraceptive adoption among women in four economically and culturally distinct areas of India. Data from India's 1998-1999 National Family Health Survey-2 and a follow-up survey in 2002-2003 for which the same women in four states were reinterviewed are analyzed. The focus of the analysis is on how baseline exposure to physical domestic violence is associated with the intersurvey adoption of contraception. Women who experience physical violence from their husbands are significantly less likely to adopt contraception in the intersurvey period, although this relationship varies by State. This study builds upon previous work by using an indicator of physical domestic violence exposure that is measured before contraceptive adoption, thus allowing the identification of how exposure to violence shapes the adoption of contraception. The results demonstrate that for women living in Bihar and Jharkhand there is a clear negative relationship between physical domestic violence and a woman's adoption of contraception; this relationship was not found for women in Maharashtra and Tamil Nadu. The results point to the need to include domestic violence screening and referral services into family planning services.

    Full Text Available Disasters are the coincidences between hazardous events, elements at risk, and conditions of vulnerability. Vulnerability integrates social and environmental systems to reduce the intensity and frequency of these risks. By categorizing regions according to their level of vulnerability, one can examine and assess the possible impacts of developmental and environmental degradation processes. This study is an attempt to map the sub-national areas (districts in India that are vulnerable to natural and climate-induced disasters. The assessment is considered under the framework of Intergovernmental Panel on Climate Change definition of vulnerability. Using analytical hierarchy process as a multi-criteria decision-mapping method, vulnerability is measured in terms of exposure, sensitivity, and adaptive capacity. Based on this mapping assessment, districts in the state of Arunachal Pradesh, Assam, Bihar, Himachal Pradesh, Jharkhand, Manipur, Meghalaya, Mizoram, Uttar Pradesh, Uttarakhand, and West Bengal are the most vulnerable regions; while districts in the state of Punjab, Haryana, Gujarat, Tamil Nadu, Maharashtra, Goa, Andhra Pradesh, Kerala, and Karnataka are among the least vulnerable regions. The results of this study can serve as the basis for targeting prioritization efforts, emergency response measures, and policy interventions at district level for mitigating disaster vulnerability in the country.

    A multimedia awareness and advocacy campaign for mainstreaming gestational diabetes mellitus (GDM) in the public health domain is described. The multimedia campaign has created awareness about the relevance of GDM to women's health and the health of future generations through direct contact, reaching out to over half a million people in 7 districts of 4 states in northern India. Using mass media, over 3.7 million people have received information on GDM. Through multistakeholder forums, more than 1000 key stakeholders have been encouraged to mainstream GDM into the existing health delivery system. The Indian Ministry of Health has introduced free screening for GDM among the 5 services offered to pregnant women below the poverty line in the National Rural Health Mission (NRHM) program. In addition, several state governments, such as in Bihar, Delhi, Jharkhand, and Punjab, have pledged similar initiatives addressing GDM; the Government of Tamil Nadu is already implementing such a policy. Policy development is a complex process that requires action on many fronts. By showcasing evidence, raising awareness, creating public opinion through dialogue and discussion, media can help build a positive environment and momentum for effective policy creation as well as service utilization.

    Phosphine (PH3) fumigation is the primary method worldwide for controlling insect pests of stored commodities. Over-reliance on phosphine, however, has led to the emergence of strong resistance. Detailed genetic studies previously identified two loci, rph1 and rph2, that interact synergistically to create a strong resistance phenotype. We compared the genetics of phosphine resistance in strains of Rhyzopertha dominica and Tribolium castaneum from India and Australia, countries having similar pest species but widely differing in pest management practices. Sequencing analysis of the rph2 locus, dihydrolipoamide dehydrogenase (dld), identified two structurally equivalent variants, Proline49>Serine (P49S) in one R. dominica strain and P45S in three strains of T. castaneum from India. These variants of the DLD protein likely affect FAD cofactor interaction with the enzyme. A survey of insects from storage facilities across southern India revealed that the P45/49S variant is distributed throughout the region at very high frequencies, in up to 94% of R. dominica and 97% of T. castaneum in the state of Tamil Nadu. The abundance of the P45/49S variant in insect populations contrasted sharply with the evolutionary record in which the variant was absent from eukaryotic DLD sequences. This suggests that the variant is unlikely to provide a strong selective advantage in the absence of phosphine fumigation.

    Dipak Suryawanshi

    Full Text Available BACKGROUND: It seems generally accepted that targeted interventions in India have been successful in raising condom use between female sex workers (FSWs and their clients. Data from clients of FSWs have been under-utilised to analyse the risk environments and vulnerability of both partners. METHODS: The 2009 Integrated Biological and Behavioural Assessment survey sampled clients of FSWs at hotspots in Andhra Pradesh, Maharashtra and Tamil Nadu (n=5040. The risk profile of clients in terms of sexual networking and condom use are compared across usual pick-up place. We used propensity score matching (PSM to estimate the average treatment effect on treated (ATT of intervention messages on clients' consistent condom use with FSW. RESULTS: Clients of the more hidden sex workers who solicit from home or via phone or agents had more extensive sexual networks, reporting casual female partners as well as anal intercourse with male partners and FSW. Clients of brothel-based sex workers, who were the least educated, reported the fewest number/categories of partners, least anal sex, and lowest condom use (41%. Consistent condom use varied widely by state: 65% in Andhra Pradesh, 36% in Maharashtra and 29% in Tamil Nadu. Exposure to intervention messages on sexually transmitted infections was lowest among men frequenting brothels (58%, and highest among men soliciting less visible sex workers (70%. Exposure had significant impact on consistent condom use, including among clients of home-based sex workers (ATT 21%; p=0.001 and among men soliciting other more hidden FSW (ATT 17%; p=0.001. In Tamil Nadu no impact could be demonstrated. CONCLUSION: Commercial sex happens between two partners and both need to be, and can be, reached by intervention messages. Commercial sex is still largely unprotected and as the sex industry gets more diffuse a greater focus on reaching clients of sex workers seems important given their extensive sexual networks.

    2017-08-01

    Spatial and temporal precipitation variability in Chhattisgarh State in India was examined by using monthly precipitation data for 102 years (1901-2002) from 16 stations. The homogeneity of precipitation data was evaluated by the double-mass curve approach and the presence of serial correlation by lag-1 autocorrelation coefficient. Linear regression analysis, the conventional Mann-Kendall (MK) test, and Spearman's rho were employed to identify trends and Sen's slope to estimate the slope of trend line. The coefficient of variation (CV) was used to analyze precipitation variability. Spatial interpolation was done by a Kriging process using ArcGIS 9.3. Results of both parametric and non-parametric tests and trend tests showed that at 5 % significance level, annual precipitation exhibited a decreasing trend at all stations except Bilaspur and Dantewada. For both annual and monsoon precipitation, Sen's test showed a decreasing trend for all stations, except Bilaspur and Dantewada. The highest percentage of variability was observed in winter precipitation (88.75 %) and minimum percentage variability in annual series (14.01 %) over the 102-year periods.

    Public health importance of hand washing as well as its importance in reduction of communicable diseases such as diarrhea and acute respiratory infections have been highlighted in many studies worldwide. This study was designed to study the hand washing practices followed in two urban slums as well as to assess and compare the status of different components of hand washing at the pre- and post-intervention phases. A community-based cross-sectional intervention study on hand washing practices was carried out at two urban slums situated in two states of Eastern India with similar sociocultural and linguistic background. The study was carried out by using an interview technique as well as observation of hand washing practices. Interpersonal communication for behavioural change was chosen as a method of intervention. The majority (>90%) practiced hand washing after defecation in both the study areas. However, hand washing following all six steps and for stipulated time period was seen to be poor before intervention. Significant improvement was observed in all the aspects of hand washing after intervention in both the areas. The poor practice of hand washing was observed in some situations and needed attention. Use of soap and clean material for drying hands after hand washing was poor initially followed by improvement after intervention. Based on the findings of the study, it could be suggested that Behaviour Change Communication program should be further planned with emphasis on different components of hand washing with a final objective to bring down the incidence of target diseases.

    Both sheep and goat pox are contagious viral diseases and affect small ruminants and are caused by sheep pox virus and goat pox virus respectively that belong to genus Capripoxvirus of Poxviridae family. Huge economic losses emanating from the disease outbreaks are the results of the wool and hide damage, subsequent production losses and also the morbidities and mortalities associated with the disease. This communication highlights clinico-epidemiological observations from the two sheep pox and one goat pox outbreaks. Grossly, multisystemic nodular lesions, mucopurulent nasal discharges and respiratory symptoms were observed in the affected animals. The morbidity, mortality and case fatality rates were 5.18%, 2.45% and 32.37%, respectively. Histopathological, haematological, molecular and serological techniques and also isolation of virus in embryonated chicken eggs were used for the diagnosis of the diseases. The spatial distribution of the disease signifies the role of common pasturelands used for grazing the animals while temporally all three outbreaks occurred in winters and were probably associated with cold stress and fodder scarcity. This is the first recorded report of Capripoxvirus infection in recent times and it highlights the disease as one of the emerging diseases in the northern state of Himachal Pradesh in India. © 2010 Blackwell Verlag GmbH.

    India is expected to add 40 billion m2 of new buildings till 2050. Buildings are responsible for one third of India’s total energy consumption today and building energy use is expected to continue growing driven by rapid income and population growth. The implementation of the Energy Conservation Building Code (ECBC) is one of the measures to improve building energy efficiency. Using the Global Change Assessment Model, this study assesses growth in the buildings sector and impacts of building energy policies in Gujarat, which would help the state adopt ECBC and expand building energy efficiency programs. Without building energy policies, building energy use in Gujarat would grow by 15 times in commercial buildings and 4 times in urban residential buildings between 2010 and 2050. ECBC improves energy efficiency in commercial buildings and could reduce building electricity use in Gujarat by 20% in 2050, compared to the no policy scenario. Having energy codes for both commercial and residential buildings could result in additional 10% savings in electricity use. To achieve these intended savings, it is critical to build capacity and institution for robust code implementation.

  9. Measurements of Indoor Radon Levels in India using Solid State Nuclear Track Detectors: Need for Standardisation

    1992-10-01

    Full Text Available Solid-state nuclear track detectors are being used to obtain the time integrated concentration levels of indoor radon/thoron and their daughters. This technique is preferred for taking such measurements in dwellings. Such measurements are important as the radiation dose to human beings due to indoor radon constitutes more than 50 per cent of the total dose including that received from the natural sources. Normalisation is necessary to obtain a representative value of the effective dose equivalent to the population. Indoor measurements carried out by several laboratories all over the country show that the indoor radon levels vary from 1.5 to about 2000 Bq m/sup -3/, while the normal level is in the range of 10 to 60 Bq m/sup -3/. It is rather difficult to compare the levels since the exposure conditions, the period of measurements and the calibration techniques used are not standardised. The present paper discusses the measurements of indoor radon in India by various groups and the important problems associated with the standardisation of these measurements. The standardisation procedure and the calibration set-up developed at this laboratory are also presented.

    Full Text Available Abstract A study on the native uses of ethnobotanical species was carried out in the south Surguja district of Chhattisgarh state in India with the major objective of identifying different food and medicinal plant species and also to understand their ongoing management and conservation. Through questionnaire and personal interviews, a total of 73 ethnobotanical species used by tribal and non-tribal communities were documented, of these 36 species were used in curing different types of diseases and 22 were used as edible food plants. This rich traditional knowledge of local people has an immense potential for pharmacological studies. The outside forces, at present, were mainly blamed to change the traditional system of harvesting and management of ethnobotanical species. The destructive harvesting practices have damaged the existing populations of many ethnobotanical species viz., Asparagus racemosus, Dioscorea bulbifera, Boswellia serrata, Buchnania lanzan, Sterculia urens and Anogeissus latifolia. The sustainable harvesting and management issues of ethnobotanical species are discussed in view of their conservation and management.

    2016-04-01

    Spatial and temporal precipitation variability in Chhattisgarh State in India was examined by using monthly precipitation data for 102 years (1901-2002) from 16 stations. The homogeneity of precipitation data was evaluated by the double-mass curve approach and the presence of serial correlation by lag-1 autocorrelation coefficient. Linear regression analysis, the conventional Mann-Kendall (MK) test, and Spearman's rho were employed to identify trends and Sen's slope to estimate the slope of trend line. The coefficient of variation (CV) was used to analyze precipitation variability. Spatial interpolation was done by a Kriging process using ArcGIS 9.3. Results of both parametric and non-parametric tests and trend tests showed that at 5 % significance level, annual precipitation exhibited a decreasing trend at all stations except Bilaspur and Dantewada. For both annual and monsoon precipitation, Sen's test showed a decreasing trend for all stations, except Bilaspur and Dantewada. The highest percentage of variability was observed in winter precipitation (88.75 %) and minimum percentage variability in annual series (14.01 %) over the 102-year periods.

  15. Spending to save? State health expenditure and infant mortality in India.

    There are severe inequalities in health in the world, poor health being concentrated amongst poor people in poor countries. Poor countries spend a much smaller share of national income on health expenditure than do richer countries. What potential lies in political or growth processes that raise this share? This depends upon how effective government health spending in developing countries is. Existing research presents little evidence of an impact on childhood mortality. Using specifications similar to those in the existing literature, this paper finds a similar result for India, which is that state health spending saves no lives. However, upon allowing lagged effects, controlling in a flexible way for trended unobservables and restricting the sample to rural households, a significant effect of health expenditure on infant mortality emerges, the long run elasticity being about -0.24. There are striking differences in the impact by social group. Slicing the data by gender, birth order, religion, maternal and paternal education and maternal age at birth, I find the weakest effects in the most vulnerable groups (with the exception of a large effect for scheduled tribes).

    Full Text Available Aim: The present study was conducted to ascertain the prevalence of ketosis in dairy cows in dairy herds, milksheds, and mixed population of milk cows selected randomly in milkshed areas of Odisha state, India. Materials and Methods: The investigation was conducted in 280 private dairy herds with variable herd size of 10-15 cows comprising crossbred Jersey cows (CBJ, crossbred Holstein Friesian (CHF cows, and indigenous local breeds. The analysis of urine (Rothera’s test, milk (Ross test, and blood samples of 2760 test cows were conducted through qualitative assessment by Rothera’s test and Ross test, respectively, for the presence of ketone bodies to screen the ketotic animals. Cut-points have been decided based on β-hydroxybutyric acid level (≥1.2-1.4 mmol/L in milk. Results: We noted positive cases of ketosis with a prevalence rate of 36.7% (1014/2760 entailing 27.2% in clinical ketosis and 9.6% in subclinical ketosis. The breed wise incident rate was recorded to be the highest (38.0% in CBJs. The age-wise prevalence rate was found to be the highest (40.8% in the age group of 5.5-6.5 years. The season wise prevalence rate in 5th calver was recorded to be the highest (38.6% in summer season as compared to other seasons. The prevalence of ketosis was observed to be the highest at 56.7% on the first stage of lactation at the 1st month after 2 weeks. The incidence rates for clinical and subclinical ketosis were found to be 25.2%; 12.2%, 26.6%; 11.2% and 30.3%; 2.9% in CBJ, CHF and indigenous cows, respectively. The breed wise overall prevalence rate was recorded to be 38.0% in CBJ, 37.8% in CHF, and 33.2% in indigenous cows. Conclusion: Ketosis and subclinical ketosis is highly prevalent metabolic disorder and has severe effect on the production status of affected animal and needs to be prevented, rather than treated, by maintaining cows in good and healthy conditions. We have attempted to give great attention for diagnosis, management

    As part of a country-wide modified leprosy elimination campaign (MLEC) carried out in 21 selected States in India in 1998, the State of Orissa launched activities in early January of that year, during which 28.9 million people were examined, giving 85% coverage of the enumerated population. Using general health care staff and volunteers, 416,604 suspect cases were identified and 62,804 of these were confirmed as leprosy by experience observers. The period of intensive search activity lasted 1 week only, but this was preceded by several months of community mobilization and involvement, health education, training of government and voluntary staff, media messages and the involvement of all relevant health departments, officials and politicians. Both this and the intensive search period were characterized by a high level of interest and cooperation by all concerned. The total of new cases detected and put on treatment (multi-drug therapy; MDT) during the period of only 7 days was approximately equal to that which, on routine population survey by the leprosy services, would be recorded over a period of 2 years. The MLEC in Orissa is judged to have been not only an historic step forward in the control of leprosy in a State previously classified as highly endemic for leprosy, but also one of the most successful State health interventions ever mounted. In the 5 months after completion of the campaign, the voluntary reporting rate increased from 50 to 90%. As a direct result of the campaign, facilities for the diagnosis and treatment of leprosy are now available daily in an additional 1639 institutions, over and above those in existence before the campaign was launched. The achievements in terms of detecting hidden (and thus undiagnosed and untreated) cases exceeded the outset predictions, underlining the importance of continued vigilance and the need to maintain involvement of general health care staff. It is anticipated that the rise in prevalence due to the addition of

    Evidence from developing countries demonstrates a mixed relationship of overweight/obesity with socioeconomic status (SES) and place of residence. Theory of nutrition transition suggests that over the course of development, overweight first emerges among rich and urban people before spreading among rural and poor people. India is currently experiencing a rapid rise in the proportion of overweight and obese population especially among adult women. Under the backdrop of huge socio-economic heterogeneity across the states of India, the inter-state scenario of overweight and obesity differs considerably. Hence, this paper investigates the evolution over time of overweight and obesity among ever-married Indian women (15-49 years) from selected 'underweight states' (Bihar, Orissa and Madhya Pradesh, where underweight proportion is predominant) and 'overweight states' (Kerala, Delhi and Punjab, where overweight is the prime concern), in relation to a few selected socio-economic and demographic indicators. This study analysed National Family Health Surveys- NFHS-2 (1998-99) and NFHS-3 (2005-06) following Asian population specific BMI cut-offs for overweight and obesity. The results confirm that within India itself the relationship of overweight and obesity with place of residence and SES cannot be generalized. Results from 'overweight states' show that the overweight problem has started expanding from urban and well-off women to the poor and rural people, while the rural-urban and rich-poor difference has disappeared. On the other hand in 'underweight states' overweight and obesity have remained socially segregated and increasing strongly among urban and richer section of the population. The rate of rise of overweight and obesity has been higher in rural areas of 'OW states' and in urban areas of 'UW states'. Indian policymakers thus need to design state-specific approaches to arrest the rapid growth of overweight and its penetration especially towards under

    Full Text Available A case study was conducted to find out the groundwater potential zones in Salem, Erode and Namakkal districts, Tamil Nadu, India with an aerial extent of 360.60 km2 . The thematic maps such as geology, geomorphology, soil hydrological group, land use / land cover and drainage map were prepared for the study area. The Digital Elevation Model (DEM has been generated from the 10 m interval contour lines (which is derived from SOI, Toposheet 1:25000 scale and obtained the slope (% of the study area. The groundwater potential zones were obtained by overlaying all the thematic maps in terms of weighted overlay methods using the spatial analysis tool in Arc GIS 9.3. During weighted overlay analysis, the ranking has been given for each individual parameter of each thematic map and weights were assigned according to the influence such as soil −25%, geomorphology − 25%, land use/land cover −25%, slope − 15%, lineament − 5% and drainage / streams − 5% and find out the potential zones in terms of good, moderate and poor zones with the area of 49.70 km2 , 261.61 km2 and 46.04 km2 respectively. The potential zone wise study area was overlaid with village boundary map and the village wise groundwater potential zones with three categories such as good, moderate and poor zones were obtained. This GIS based output result was validated by conducting field survey by randomly selecting wells in different villages using GPS instruments. The coordinates of each well location were obtained by GPS and plotted in the GIS platform and it was clearly shown that the well coordinates were exactly seated with the classified zones.

    Full Text Available Background & objectives: India is a large country with each State having distinct social, cultural and economic characteristics. Tobacco epidemic is not uniform across the country. There are wide variations in tobacco consumption across age, sex, regions and socio-economic classes. This study was conducted to understand the wide inequalities in patterns of smoking and smokeless tobacco consumption across various States of India. Methods: Analysis was conducted on Global Adult Tobacco Survey, India (2009-2010 data. Prevalence of both forms of tobacco use and its association with socio-economic determinants was assessed across States and Union Territories of India. Wealth indices were calculated using socio-economic data of the survey. Concentration index of inequality and one way ANOVA assessed economic inequality in tobacco consumption and variation of tobacco consumption across quintiles. Multiple logistic regression was done for tobacco consumption and wealth index adjusting for age, sex, area, education and occupation. Results: Overall prevalence of smoking and smokeless tobacco consumption was 13.9 per cent (14.6, 13.3 and 25.8 per cent (26.6, 25.0, respectively. Prevalence of current smoking varied from 1.6 per cent (richest quintile in Odisha to 42.2 per cent (poorest quintile in Meghalaya. Prevalence of current smokeless tobacco consumption varied from 1.7 per cent (richest quintile in Jammu and Kashmir to 59.4 per cent (poorest quintile in Mizoram. Decreasing odds of tobacco consumption with increasing wealth was observed in most of the States. Reverse trend of tobacco consumption was observed in Nagaland. Significant difference in odds of smoking and smokeless tobacco consumption with wealth quintiles was observed. Concentration index of inequality was significant for smoking tobacco -0.7 (-0.62 to-0.78 and not significant for smokeless tobacco consumption -0.15 (0.01to-0.33 Interpretation & conclusions: The findings of our analysis

    Full Text Available The aim of the study is to evaluate the differences in the behavior and attitudes of male and female lawyers regarding their lifestyles and health habits. Lawyers were randomly chosen. Data was obtained through a structured questionnaire distributed among the lawyers of Coimbatore district, Tamil Nadu. Lawyers are found to have unfavorable health practices related to use of tobacco and alcohol, exercise, diet, sleeping habits, and stress. This resulted in obesity, depression, and blood pressure. Many lawyers reported use of alcohol regularly, even as often as every day, and nearly half of them smoked. Many of the lawyers had poor feeding habit of skipping meals and eating snacks as breakfast. Most lawyers considered stressful situations to be unavoidable. Thus identifying individual lawyers with poor health behaviors and providing medical help are essential.

    2012-06-01

    Full Text Available The paper studies the ‘wholesale’ market through which microfinance institutions operating in three contexts (Peru, Tanzania and the state of Tamil Nadu in India obtain loans from a variety of domestic and international funding bodies. The nature and characteristics of the relationships between them are captured through network analysis and visualization tools, with a dataset comprising inter-organisational lending relationships and organisations’ attributes over the years 2006-8. Focus is on the extent to which patterns in wholesale lending relationships relate to the legal status and characteristics of microfinance institutions; to the regulatory, business and social environment in which they operate; and to shifts in the balance between social and commercial interests of diverse types of lenders.The analysis brings to light considerable cross-country variation in the structure and features of wholesale lending relationships, and relates it primarily to differences in governance and regulation. On this basis, it makes the case that building a more enabling regulatory environment for funding partnerships may improve the capacity of microfinance to achieve its dual goals of poverty alleviation and financial sustainability.

    Full Text Available In the present context of shrinking conventional resources coupled with environmental perils, the wind power offers an attractive alternative. Wind power generation in India started way back in early 1980s with the installation of experimental wind turbines in western and southern states of Gujarat and Tamil Nadu. For first two decades of its existence until about 2000 the progress was slow but steady. In last one decade Indian wind electricity sector has grown at very rapid pace which has promoted the country to the fifth position as largest wind electric power generator and the third largest market in the world. The galvanization of wind sector has been achieved through some aggressive policy mechanisms and persistent support by government organizations such as MNRE and C-WET. This paper articulates the journey of Indian wind program right since its inception to the present trends and developments as well as the future prospects.

    Delhi is the most densely populated and urbanized city of India. The annual growth rate in population during the last decade (1991-2001) was 3.85%, almost double the national average. Delhi is also a commercial hub, providing employment opportunities and accelerating the pace of urbanization, resulting in a corresponding increase in municipal solid waste (MSW) generation. Presently the inhabitants of Delhi generate about 7000tonnes/day of MSW, which is projected to rise to 17,000-25,000tonnes/day by the year 2021. MSW management has remained one of the most neglected areas of the municipal system in Delhi. About 70-80% of generated MSW is collected and the rest remains unattended on streets or in small open dumps. Only 9% of the collected MSW is treated through composting, the only treatment option, and rest is disposed in uncontrolled open landfills at the outskirts of the city. The existing composting plants are unable to operate to their intended treatment capacity due to several operational problems. Therefore, along with residue from the composting process, the majority of MSW is disposed in landfills. In absence of leachate and landfill gas collection systems, these landfills are a major source of groundwater contamination and air pollution (including generation of greenhouse gases). This study describes and evaluates the present state of municipal solid waste management in Delhi. The paper also summarizes the proposed policies and initiatives of the Government of Delhi and the Municipal Corporation of Delhi to improve the existing MSW management system.

    Outbreaks of hepatitis C virus (HCV) infection are associated with unsafe injection practices, intravenous drug abuse and other exposure to blood and body fluids. We report here three outbreaks of HCV infection from Jammu and Kashmir (J&K) State, India, which occurred over a period of 3 years and in which molecular epidemiological investigations identified a presumptive common source of infection, most likely a single healthcare venue. Representative blood samples collected from cases of hepatitis C were sent to the National Centre for Disease Control (NCDC) for molecular characterization. These samples were positive by HCV ELISA. Subsequently, specimens were also tested for the presence of HCV RNA by RT-PCR. Sequencing was carried out for all positive samples. A total of 812 cases were laboratory confirmed by HCV ELISA; a total of 115 samples were sent to the NCDC for RT-PCR, and 77 were positive. Subtype 3a of HCV was found in all samples from Anantnag (February 2013); and for subtype 3b, in all samples from Srinagar (May 2015). Subtypes 3a and 3g were identified from two samples from the Kulgam outbreak (July 2014). A detailed epidemiological investigation should be conducted whenever a cluster of HCV cases is revealed, as this potentially allows for the identification of larger outbreaks. Epidemiological investigations of outbreaks should be further supported by inclusion of molecular tests. Efforts to limit therapeutic injections to only those cases having strong medical/surgical indications and to restrict the use of non-sterile needles are essential to prevent transmission of HCV.

    We investigated the magnitude of self-medication with antibiotics in a peri-urban area of Southern Kerala State, India and factors influencing this practice. First, a random sample of 400 households was surveyed in one primary health centre area near Trivandrum. We found 69.3% (95% CI = 64.8-73.8) of households had at least one person using a pharmaceutical product during the two-week recall period; antibiotics formed almost 11% of the medicines consumed. Next, pharmacy based interview and observation data were collected from 405 antibiotic purchasers sampled from 11 out of the 12 private pharmacies in the area. Seventy-three of these 405 customers purchased antibiotics without a prescription (18%; 95% CI = 14.3-21.7). By combining the household survey and pharmacy observations, we estimate that almost half of 1% (0.41%; 95% CI = 0.24-1.16) of the population, or four people per 1000, is engaged in self-medication using antibiotics in Kerala in any two-week period. Our data show that people least likely to follow this practice are from higher income families, having more education and higher status occupations and receiving the benefits of medical insurance. Conversely, logistic regression analysis indicated that risk of buying antibiotics without a script was associated with education at secondary level or below, the perception that it is expensive to consult a doctor and low satisfaction with medical practitioners. Keralites' self-medication patterns are interpreted broadly using social, cultural, historical and economic perspectives. Solutions to the problem of antibiotic misuse are suggested, proceeding on several fronts: among practitioners, suppliers and marketeers of medicines, and among the population of pharmaceutical consumers themselves.

    Full Text Available Background: Cutaneous leishmaniasis in India is mainly confined to the deserts of Rajasthan; some cases have been reported from the dry north-western half of the Indo-Gangetic plain, including Punjab, Himachal Pradesh, Delhi and Varanasi. Aims: To highlight a new focus of cutaneous leishmaniasis in the Jammu division of Jammu and Kashmir State, previously a non-endemic area. This report presents the clinico-epidemiological and investigative results of 120 new cases of cutaneous leishmaniasis detected between November 2012 and October 2013. Methods: The clinical diagnosis of cutaneous leishmaniasis was made using criteria proposed by Bari and Rahman. It was further confirmed by the demonstration of Leishman-Donovan bodies in Leishman stained slit skin smears and skin biopsy specimens, and/or by a satisfactory response to intra-lesional sodium stibogluconate given weekly for 4 weeks. Serial clinical photographs were taken before giving injections and at the end of the 6 th week. Results: There were 67 females and 53 males with an age range of 8 months to 80 years. The most frequently affected site was the face. Lesions were most commonly of the nodulo-ulcerative type. The number of lesions ranged from 1 to 4. Farmers (28.1%, homemakers (27.2% and students (27.2% were significantly over-represented among the occupations (P < 0.001. Skin smears and biopsies were positive for Leishman-Donovan bodies in 50.8% and 44.2% cases, respectively. Conclusions: There is a new focus of cutaneous leishmaniasis in Jammu division which deserves urgent attention from the public health angle. Further epidemiological studies are warranted to establish the identity of the vector and the strain of Leishmania involved.

    Full Text Available Introduction: Cardiometabolic health status of women is a serious public health concern. Markers of body fat content and their distribution are important indicators of cardiometabolic health risk in participants. In addition, socio-demographic status plays a determinant role. The aim of the study was to evaluate the influence of adiposity markers and socio-demographic determinants on various cardiovascular and metabolic risk factors in Indian women. Materials and Methods: The study was conducted on 388 women (age 25–65 years from Tripura, a Northeastern state of India. Various obesity and atherogenic markers such as body mass index (BMI, waist circumference (WC, waist-hip ratio, waist - height ratio, high density lipoprotein-cholesterol (HDL-C/total cholesterol, HDL-C/low density lipoprotein cholesterol, triglyceride/HDL-C ratio and traditional cardiometabolic risk factors such as high blood pressure, dyslipidemia, and glucose intolerance were evaluated in participant. The socio-demographic status included the level of education and monthly family income. Results: The cardiometabolic risk in postmenopausal women were higher than premenopausal women. The risk increases with age in both groups. Women with lower educational level and higher income group were found to be prone to higher cardiometabolic risk. Receiver operating characteristics analysis revealed central obesity marked by increased WC was a better predictor of cardiometabolic risk than general obesity marked by increased BMI. Conclusion: The cardiometabolic risk among both premenopausal and postmenopausal women are associated with central obesity which can be predicted by increased WC in the subject. Socio-demographic status of the participant plays a definitive role in determining cardiometabolic risk in women.

    The Night Frog genus Nyctibatrachus (Family Nyctibatrachidae) represents an endemic anuran lineage of the Western Ghats Biodiversity Hotspot, India. Until now, it included 28 recognised species, of which more than half were described recently over the last five years. Our amphibian explorations have further revealed the presence of undescribed species of Nights Frogs in the southern Western Ghats. Based on integrated molecular, morphological and bioacoustic evidence, seven new species are formally described here as Nyctibatrachus athirappillyensis sp. nov., Nyctibatrachus manalari sp. nov., Nyctibatrachus pulivijayani sp. nov., Nyctibatrachus radcliffei sp. nov., Nyctibatrachus robinmoorei sp. nov., Nyctibatrachus sabarimalai sp. nov. and Nyctibatrachus webilla sp. nov., thereby bringing the total number of valid Nyctibatrachus species to 35 and increasing the former diversity estimates by a quarter. Detailed morphological descriptions, comparisons with other members of the genus, natural history notes, and genetic relationships inferred from phylogenetic analyses of a mitochondrial dataset are presented for all the new species. Additionally, characteristics of male advertisement calls are described for four new and three previously known species. Among the new species, six are currently known to be geographically restricted to low and mid elevation regions south of Palghat gap in the states of Kerala and Tamil Nadu, and one is probably endemic to high-elevation mountain streams slightly northward of the gap in Tamil Nadu. Interestingly, four new species are also among the smallest known Indian frogs. Hence, our discovery of several new species, particularly of easily overlooked miniaturized forms, reiterates that the known amphibian diversity of the Western Ghats of India still remains underestimated.

    Carbapenem resistance is disseminating worldwide among Gram-negative bacteria. The aim of this study was to identify carbapenem-resistance level and to determine the mechanism of carbapenem resistance among clinical isolates from two centres in Tamil Nadu. In the present study, a total of 93 Gram-negative isolates, which is found to be resistant to carbapenem by disk diffusion test in two centres, were included. All isolates are identified at species level by 16S rRNA sequencing. Minimal inhibitory concentrations (MICs) of isolates for Meropenem were tested by agar dilution method. Presence of blaOXA, blaNDM, blaVIM, blaIMP and blaKPC genes was tested by PCR in all isolates. Amplicons were sequenced for confirmation of the genes. Among 93 isolates, 48 (%52) were Escherichia coli, 10 (%11) Klebsiella pneumoniae, nine (%10) Pseudomonas aeruginosa. Minimal inhibitory concentration results showed that of 93 suspected carbapenem-resistant isolates, 27 had meropenem MICs ≥ 2 μg/ml. The MIC range, MIC50 and MIC90 were 128 μg/ml, 0.12 and 16 μg/ml, respectively. Fig. 1 . Among meropenem-resistant isolates, E. coli were the most common (9/48, 22%), followed by K. pneumoniae (7/9, 77%), P. aeruginosa (6/10, 60%), Acinetobacter baumannii (2/2, 100%), Enterobacter hormaechei (2/3, 67%) and one Providencia rettgeri (1/1, 100%). PCR results showed that 16 of 93 carried blaNDM, three oxa181, and one imp4. Among blaNDM carriers, nine were E. coli, four Klebsiella pneumoniae, two E. hormaechei and one P. rettgeri. Three K. pneumoniae were OXA-181 carriers. The only imp4 carrier was P. aeruginosa. A total of seven carbapenem-resistant isolates were negatives by PCR for the genes studied. All carbapenem-resistance gene-positive isolates had meropenem MICs >2 μg/ml. Our results confirm the dissemination of NDM and emergence of OXA-181 beta-lactamase among Gram-negative bacteria in South India. This study showed the emergence of NDM producer in clinical isolates of E

    India is experiencing fast income growth and urbanization, and this leads to unprecedented increases in demand for building energy services and resulting energy consumption. In response to rapid growth in building energy use, the Government of India issued the Energy Conservation Building Code (ECBC) in 2007, which is consistent with and based on the 2001 Energy Conservation Act. ECBC implementation has been voluntary since its enactment and a few states have started to make progress towards mandatory implementation. Rajasthan is the first state in India to adopt ECBC as a mandatory code. The State adopted ECBC with minor additions on March 28, 2011 through a stakeholder process; it became mandatory in Rajasthan on September 28, 2011. Tamil Nadu, Gujarat, and Andhra Pradesh have started to draft an implementation roadmap and build capacity for its implementation. The Bureau of Energy Efficiency (BEE) plans to encourage more states to adopt ECBC in the near future, including Haryana, Uttar Pradesh, Karnataka, Maharashtra, West Bengal, and Delhi. Since its inception, India has applied the code on a voluntary basis, but the Government of India is developing a strategy to mandate compliance. Implementing ECBC requires coordination between the Ministry of Power and the Ministry of Urban Development at the national level as well as interdepartmental coordination at the state level. One challenge is that the Urban Local Bodies (ULBs), the enforcement entities of building by-laws, lack capacity to implement ECBC effectively. For example, ULBs in some states might find the building permitting procedures to be too complex; in other cases, lack of awareness and technical knowledge on ECBC slows down the amendment of local building by-laws as well as ECBC implementation. The intent of this white paper is to share with Indian decision-makers code enforcement approaches: through code officials, third-party inspectors, or a hybrid approach. Given the limited capacity and human

    2015-01-01

    Full Text Available Background: While the roles and responsibilities of nursing professionals have multiplied over the years, but there are huge concerns with regard to the development of the nursing workforce and human resources (HR issues for their career growth. The major lacuna is in not involving the nursing professionals in policy framing and decision-making. As a result, there is a leadership crisis of the nursing workforce across India. Objectives: The paper, is part of the WHO supported study, entitled "Study on Nursing and Midwifery in India: a critical review", is developed with the objective to review the current organizational and management structure for the nursing positions at the State Directorates in India and obtain a Leadership perspective to strengthen nursing management capacities to address maternal health issues. Materials and Methods: The study descriptive and qualitative in nature and the sources of information were both primary and secondary collected from 16 states of India. Results: Since none of the states have neither a Nursing Cell nor the post of Director Nursing, final decision-making powers rest with state health secretaries and medical directors. The nursing management structure majorly managed by senior policy makers from the medical fraternity, and provides very little scope for nursing professionals to participate in policy decision making to bring about reforms. There is no uniformity on HR issues concerning career graphs and pay structures across the states. Conclusions: In order to strengthen nursing as a profession and for facilitating their role at the policy level, more powers and autonomy needs to be given to them and this requires HR policy guidelines for nurses. Setting up a separate nursing directorate, to be headed by a senior nursing professional, is suggested in every state along with a strong nursing division at the National level. This total paradigm shift will empower nursing professionals to take up the

    Peste-des-petits- ruminants (PPR) is a highly contagious and devastating disease of goats and sheep. Although India is endemic for PPR, Tripura, a state in North East India has never been reported confirmed PPR outbreaks. Recently, an outbreak of PPR occurred in non-descript goats at the Sabroom town of Tripura state in North-East India in June, 2013. The causative agent, PPR virus (PPRV) was confirmed by sandwich ELISA, virus isolation and N gene based RT-PCR and sequencing. The sequence and phylogenetic analysis confirmed the involvement of lineage IV PPR virus in the outbreak. The outbreak viruses from Tripura state were clustered mainly with circulating viruses from Bangladesh, India, China, Pakistan, Tajikistan, Dubai and Kurdistan. However, the nucleotide sequence homology ranged from 99.2 to 99.6% with the PPR strains circulating in Bangladesh during 2011 and 2012 whereas 95.5-98% homology has been observed with the viruses from India and other countries. These findings suggest the transboundary circulation of PPR virus between India and Bangladesh border, which warrant immediate vaccination across the international border to create an immune belt.

    2016-01-01

    Full Text Available Background & objectives: Malaria has become endemic and subject of concern in most part of the India especially Northeastern states of India. Surveys before 2000 revealed that Anopheles minimus was major vector responsible for transmission of malaria in this region followed by An. dirus and An. fluviatilis. However, recent studies indicate replacement of An. minimus vector by An. culicifacies due to different ecological changes and change in landuse pattern etc. The objective of present study was to explore the vectorial role of An. culicifacies in transmission of malaria in four malaria endemic states, viz. Assam, Meghalaya, Manipur and Sikkim of India. Methods: The seven surveys were conducted in 176 selected villages belonging to eight districts of the four states in both pre-monsoon (March-April and post-monsoon (September-October seasons from 2010 to 2013. However, in 2011 surveys could not be carried out due to public inconvenience in pre-monsoon season. For vectorial role of all vector species collected, ELISA and PCR were assayed. Results: A total of 19,173 specimens belonging to 30 anopheline species were collected, out of which 4315 belonged to four established vector species. In total, 4183 specimens were processed through ELISA, out of which 236 specimens were found positive for circumsporozoite (CS protein. Further, infectivity was confirmed by PCR in 35 samples, of which 12 samples were found positive for Plasmodium falciparum and three for P. vivax. Out of 12 Plasmodium falciparum positive samples, nine samples were positive for An. culicifacies, two for An. fluviatilis and one for An. minimus. While out of three Plasmodium vivax positive samples, two samples were positive for An. dirus and one sample was positive for An. culicifacies. Interpretation & conclusion: Anopheles culicifacies replaced the An. minimus, the vector of malaria in Northeastern states of India, as it was found to be highly infected with malaria parasite as

    Conservation of biodiversity has been put to the highest priority throughout the world. The process of identifying threatened ecosystems will search for different drivers related to biodiversity loss. The present study aimed to generate spatial information on deforestation and ecological degradation indicators of fragmentation and forest fires using systematic conceptual approach in Telangana state, India. Identification of ecosystems facing increasing vulnerability can help to safeguard the extinctions of species and useful for conservation planning. The technological advancement of satellite remote sensing and Geographical Information System has increased greatly in assessment and monitoring of ecosystem-level changes. The areas of threat were identified by creating grid cells (5 × 5 km) in Geographical Information System (GIS). Deforestation was assessed using multi-source data of 1930, 1960, 1975, 1985, 1995, 2005 and 2013. The forest cover of 40,746 km(2), 29,299 km(2), 18,652 km(2), 18,368 km(2), 18,006 km(2), 17,556 km(2) and 17,520 km(2) was estimated during 1930, 1960, 1975, 1985, 1995, 2005 and 2013, respectively. Historical evaluation of deforestation revealed that major changes had occurred in forests of Telangana and identified 1095 extinct, 397 critically endangered, 523 endangered and 311 vulnerable ecosystem grid cells. The fragmentation analysis has identified 307 ecosystem grid cells under critically endangered status. Forest burnt area information was extracted using AWiFS data of 2005 to 2014. Spatial analysis indicates total fire-affected forest in Telangana as 58.9% in a decadal period. Conservation status has been recorded depending upon values of threat for each grid, which forms the basis for conservation priority hotspots. Of existing forest, 2.1% grids had severe ecosystem collapse and had been included under the category of conservation priority hotspot-I, followed by 27.2% in conservation priority hotspot-II and 51.5% in conservation

    Full Text Available Soil organic carbon has been ignored since long because it was treated as a dead biomass. After the awareness of climate change, its importance has been recognized worldwide. Carbon remains in the soil for much longer duration than the carbon in the vegetation that the soils support. A study was undertaken to estimate the Soil Organic Carbon Stock under forests in Haryana state of India. SOC stock under different forests in Haryana was estimated and data reveals that maximum SOC stock (58.24 t ha-1 was under chir (Pinus roxburghii, followed by dhak (B. monosperma (51.41 t ha-1, miscellaneous forests (43.55 t ha-1 and the least was under sal (Shorea robusta (40.97 t ha-1. Organic carbon stock under chir was 33.73 % and 42.15 % higher as compared to miscellaneous and sal respectively. SOC stock under miscellaneous was 6.30 % higher as compared to sal. Maximum SOC stock was in the forests under north circle (4326371.19 t which is 54.89 % of total SOC stock of Haryana forests and the least was in central circle (1078400.07 t, 13.68 % of total SOC stock of Haryana forests. Maximum organic carbon stock was in the soils in Panchkula district i.e. 21,16,652.22 tons which was 26.85 % of the total SOC stock in Haryana followed by in Yamunanagar district which contains 11,13,145.25 t which was 14.12 % of total stock of Haryana. Among the Wild life sanctuaries, Conservation reserves and National parks, maximum SOC stock was under wild life sanctuaries (1.09 million tons which was 66.65 % of the total SOC stock under NP, WLS and CR, followed by conservation reserves (0.30 million tons which was 18.43 % of total SOC stock in NP, WLS and CR and the least was in national parks (0.25 million tons.

    Full Text Available Availability of veterinary services is very important for development of livestock sector in India. In many locations apart from state veterinary services other veterinary services are also available and the veterinary service users have the choice available with them regarding the service providers. The preference of service providers depend upon the location, distance, livestock holding and capacity to pay and quality of services. A study was conducted among the livestock owners of Sangli district in Maharastra to assess the preference of the livestock owners towards a particular veterinary service provider. Majority of large farmers preferred state veterinary services and cooperative veterinary services where it had strong presence. Cooperative veterinary service can be a good alternative to the state veterinary services and the private veterinary service providers are still not preferred in the rural area. [Vet.

    In this paper the problems of health services in China and India are related to some structural features of the two economies. Some similarities and differences exist across these two countries in terms of political economy, with differential results. Both countries have experienced remarkable economic growth during the past quarter-century, but this has not always translated into improvements in health for the poor. Although China used to have an egalitarian basic public health service, the system has become quite inegalitarian during the past quarter-century, with the disintegration of the communes and adoption of fee-based services under a system of decentralized public finance. India's health system has remained inegalitarian throughout.

    Intra venous drug users (IVDUs) are at high risk for hepatitis C virus (HCV) infection owing to their high rate of drug abuses. The north-eastern part of India has a high prevalence of IVDUs with Manipur being the worst hit state. The aim of the study was to document the molecular epidemiology, the patterns of HCV transmission, genomic variation and recombination events within HCV genome among IVDUs of Manipur, India. 91 anti-HCV sero-reactive blood samples were collected from IVDUs in Manipur. The samples were processed for RNA extraction, nested RT-PCR, sequencing and quantitative viral RNA estimation. Phylogeographic analysis of the sequenced core and NS5B regions of HCV genome was performed to determine the probable transmission route and recombinant HCV strains. 83 out of 91 anti-HCV seropositive samples were RNA positive (91.20%) based on 5'UTR of HCV genome by nested RT-PCR. Of the RNA positive samples, 73 paired partial core and NS5B gene were sequenced. Three major genotype and eight subtypes were detected while no recombinant strains were found. Individuals with genotype 1 had the mean viral load (5.94 ± 0.705 log10IU/ml) followed by genotype 3 (4.91 ± 0.49 log10IU/ml) and 6 (3.96 ± 0.32 log10IU/ml). The viral load was statistically significant among the male individuals at 4.822 ± 1.36 log10IU/ml compared to 4.767 ± 0.49 log10IU/ml for females (t=3.249, pManipur reflects the transmission of these strains from the "Golden Triangle" drug trafficking regions. Sequence analysis confirmed the transmission routes of HCV, which is linked to China and Vietnam for the newly emergent genotype 6 in north-eastern India.

    Using data from India, we estimate the relationship between household wealth and children's school enrollment. We proxy wealth by constructing a linear index from asset ownership indicators, using principal-components analysis to derive weights. In Indian data this index is robust to the assets included, and produces internally coherent results. State-level results correspond well to independent data on per capita output and poverty. To validate the method and to show that the asset index predicts enrollments as accurately as expenditures, or more so, we use data sets from Indonesia, Pakistan, and Nepal that contain information on both expenditures and assets. The results show large, variable wealth gaps in children's enrollment across Indian states. On average a "rich" child is 31 percentage points more likely to be enrolled than a "poor" child, but this gap varies from only 4.6 percentage points in Kerala to 38.2 in Uttar Pradesh and 42.6 in Bihar.

    Background Dengue is a recently emerging vector borne diseases in Chennai. As per the WHO report in 2011 dengue is one of eight climate sensitive disease of this century. Objective Therefore an attempt has been made to explore the influence of climate parameters on dengue occurrence and use for forecasting. Methodology Time series analysis has been applied to predict the number of dengue cases in Chennai, a metropolitan city which is the capital of Tamil Nadu, India. Cross correlation of the climate variables with dengue cases revealed that the most influential parameters were monthly relative humidity, minimum temperature at 4 months lag and rainfall at one month lag (Table 1). However due to intercorrelation of relative humidity and rainfall was high and therefore for predictive purpose the rainfall at one month lag was used for the model development. Autoregressive Integrated Moving Average (ARIMA) models have been applied to forecast the occurrence of dengue. Results and Discussion The best fit model was ARIMA (1,0,1). It was seen that the monthly minimum temperature at four months lag (β= 3.612, p = 0.02) and rainfall at one month lag (β= 0.032, p = 0.017) were associated with dengue occurrence and they had a very significant effect. Mean Relative Humidity had a directly significant positive correlation at 99% confidence level, but the lagged effect was not prominent. The model predicted dengue cases showed significantly high correlation of 0.814(Figure 1) with the observed cases. The RMSE of the model was 18.564 and MAE was 12.114. The model is limited by the scarcity of the dataset. Inclusion of socioeconomic conditions and population offset are further needed to be incorporated for effective results. Conclusion Thus it could be claimed that the change in climatic parameters is definitely influential in increasing the number of dengue occurrence in Chennai. The climate variables therefore can be used for seasonal forecasting of dengue with rise in minimum

    Full Text Available This article reports on a Public Private Partnership (PPP program in South India that provided information and communication technology (ICT to rural elementary schools. The article examined the current status of rural, government-run elementary schools in India by reviewing reports like the Annual Status of Education Report (ASER in India. Challenges like teacher absences, student drop-outs, lack of electricity, lack of separate toilets for genders, and a lack of teaching resources is discussed. To meet these challenges, the article describes the rise in popularity of India’s PPPs. Then the article reports on a case study of a PPP, called the SSA Foundation, which implemented a “one laptop per school” program in rural areas in the Indian States of Karnataka and Tamil Nadu. Using ethnographic data from field research, the case study includes a description of how the students in a rural Karnataka elementary school use their school’s laptop. The school was situated in a small village where most travel was non-motorized. Walking, usually without shoes, was the main form of transportation. A bicycle was considered a luxury. Most villagers worked in the surrounding ragi and millet fields; laboring, often with only simple tool blades. Wood fires were the main source of fuel for cooking. In this village, the school’s laptop became a prized possession. The case study offers a “thick description” (Geertz, 1973 of how the village school’s students used the laptop for learning basic computing skills and for learning English.

    To investigate the association between physical intimate partner violence (IPV) and sexually transmitted infection (STI) in two national samples. Data came from the National Epidemiologic Survey on Alcohol and Related Conditions Wave 2 (n=34,653) and the National Family Health Survey-3 (n=124 385). Ever-married women between the ages of 20 and 49 were asked if they had experienced physical violence by their partner in the past year. Outcomes were presence of doctor confirmed HIV and self-reported STI. Age at first intercourse was examined as a mediator of the relationship between IPV and STI. Logistic regression examined associations between IPV, age at first intercourse and STI. Compared to individuals with no physical IPV, risk for STI was higher for individuals who experienced past year IPV living in the United States and India, however once controlling for age at first intercourse, age, education, household wealth/income and past year sexual violence, the relationship between IPV, and STI was significant in the American sample [(AOR)=1.65, 95% (CI)=1.21-2.26], however not for individuals living in India [(AOR)=1.75, 95% (CI)=0.84-3.65]. Individuals with exposure to physical IPV are at increased odds for STI. Age at first intercourse although a marker of risk, may not be an accurate marker of risky sexual behavior in both samples.

    We have measured black carbon properties by using a size-selected single-particle soot photometer (SP2). The measurements were conducted in northern India at two sites: Gual Pahari is located at the Indo-Gangetic Plain (IGP) and Mukteshwar at the Himalayan foothills. Northern India is known as one of the absorbing aerosol hot spots, but detailed information about absorbing aerosol mixing state is still largely missing. Previous equivalent black carbon (eBC) mass concentration measurements are available for this region, and these are consistent with our observations showing that refractory black carbon (rBC) concentrations are about 10 times higher in Gual Pahari than those at Mukteshwar. Also, the number fraction of rBC-containing particles is higher in Gual Pahari, but individual rBC-containing particles and their size distributions are fairly similar. These findings indicate that particles at both sites have similar local and regional emission sources, but aerosols are also transported from the main source regions (IGP) to the less polluted regions (Himalayan foothills). Detailed examination of the rBC-containing particle properties revealed that they are most likely irregular particles such as fractal aggregates, but the exact structure remains unknown.

    Recent trends in climate, land-use pattern and population has affected almost every portable water resources in the world. Due to depleting surface water and untimely distribution of precipitation, the demand to use groundwater has increased considerably. Further recent studies have shown that the groundwater stress is more in developing countries like India. This study focuses on understanding the impacts of three major factors (i.e., rainfall, land-cover and population growth) effecting the groundwater levels. For this purpose, the correlation between the trends in groundwater time series is compared with trends in rainfall, land-cover and population growth. To detect the trends in time series, two statistical methods namely, least square method and Mann-Kendall method, are adopted. The results were analyzed based on the measurements from 1800 observation wells in the Karnataka state, India. The data is obtained for a total of 9 year time period ranging from 2005 to 2013. A gridded precipitation data of 0.5o× 0.5o over the entire region is used. The change in land-cover and population data was approximately obtained from the local governing bodies. The early results show significant correlation between rainfall and groundwater time series trends. The outcomes will assess the vulnerability of groundwater levels under changing physical and hydroclimatic conditions, especially under climate change.

    In many regions around the globe, including India, degradation in the quality of groundwater is of great concern. The objective of this investigation is to determine the effect of recharge from a check dam on quality of groundwater in a region of Krishnagiri District of Tamil Nadu State, India. For this study, water samples from 15 wells were periodically obtained and analysed for major ions and fluoride concentrations. The amount of major ions present in groundwater was compared with the drinking water guideline values of the Bureau of Indian Standards. With respect to the sodium and fluoride concentrations, 38% of groundwater samples collected was not suitable for direct use as drinking water. Suitability of water for agricultural use was determined considering the electrical conductivity, sodium adsorption ratio, sodium percentage, permeability index, Wilcox and United States Salinity Laboratory diagrams. The influence of freshwater recharge from the dam is evident as the groundwater in wells nearer to the check dam was suitable for both irrigation and domestic purposes. However, the groundwater away from the dam had a high ionic composition. This study demonstrated that in other fluoride-affected areas, the concentration can be reduced by dilution with the construction of check dams as a measure of managed aquifer recharge.

    Full Text Available Background: Adolescent suicide is an important public health issue. Suicidal ideations are often the precursor of suicide and can be targeted by appropriate and timely interventions. Aims and Objectives: To determine the prevalence of suicide ideation and to study its predictive factors among school going adolescents. Materials and Methods: This cross-sectional study was carried out in selected senior secondary schools in Shimla district of Himachal Pradesh, India. A pre-validated, self-administered questionnaire was used for data collection. Both descriptive and inferential statistics were applied using Epi info software for windows (CDC Atlanta software for windows. Results: A total of 218 study subjects (30.9%; confidence interval = 27.6–34.5% had suicide ideation. Discussing problems with parents (adjusted odds ratio [AOR] =0.5, having good relations with school teachers (AOR = 0.6 and helpful classmates (AOR = 0.6 lowered the odds of having suicidal ideations. On the contrary, adolescents having worrying issues in family (AOR = 2.5, verbally or physically abused (AOR = 2.8 and body image conscious (AOR = 1.8 had increased odds of suicidal ideations. Conclusions: Suicidal ideation is a common experience among adolescents residing in Shimla district of North India. The supportive environment at home and in school decrease its vulnerability.

  4. Policy Preferences about Managed Aquifer Recharge for Securing Sustainable Water Supply to Chennai City, India

    Full Text Available The objective of this study is to bring out the policy changes with respect to managed aquifer recharge (focusing on infiltration ponds, which in the view of relevant stakeholders may ease the problem of groundwater depletion in the context of Chennai City; Tamil Nadu; India. Groundwater is needed for the drinking water security of Chennai and overexploitation has resulted in depletion and seawater intrusion. Current policies at the municipal; state and national level all support recharge of groundwater and rainwater harvesting to counter groundwater depletion. However, despite such favorable policies, the legal framework and the administrative praxis do not support systematic approaches towards managed aquifer recharge in the periphery of Chennai. The present study confirms this, considering the mandates of governmental key-actors and a survey of the preferences and motives of stakeholder representatives. There are about 25 stakeholder groups with interests in groundwater issues, but they lack a common vision. For example, conflicting interest of stakeholders may hinder implementation of certain types of managed aquifer recharge methods. To overcome this problem, most stakeholders support the idea to establish an authority in the state for licensing groundwater extraction and overseeing managed aquifer recharge.

    Manipur State, with a population of 2.29 million, is one of the seven North-Eastern Hill states in India, and is severely affected by groundwater arsenic contamination. Manipur has nine districts out of which four are in Manipur Valley where 59% of the people live on 10% of the land. These four districts are all arsenic contaminated. We analysed water samples from 628 tubewells for arsenic out of an expected total 2,014 tubewells in the Manipur Valley. Analyzed samples, 63.3%, contained >10 μg/l of arsenic, 23.2% between 10 and 50 μg/l, and 40% >50 μg/l. The percentages of contaminated wells above 10 and 50 μg/l are higher than in other arsenic affected states and countries of the Ganga-Meghna-Brahmaputra (GMB) Plain. Unlike on the GMB plains, in Manipur there is no systematic relation between arsenic concentration and the depth of tubewells. The source of arsenic in GMB Plain is sediments derived from the Himalaya and surrounding mountains. North-Eastern Hill states were formed at late phase of Himalaya orogeny, and so it will be found in the future that groundwater arsenic contamination in the valleys of other North-Eastern Hill states. Arsenic contaminated aquifers in Manipur Valley are mainly located within the Newer Alluvium. In Manipur, the high rainfall and abundant surface water resources can be exploited to avoid repeating the mass arsenic poisoning that has occurred on the GMB plains.

    Scrub typhus is a major public health threat in South and Southeastern Asian countries including India. Understanding local patterns of disease and factors that place individuals at risk is pivotal to future preventive measures against scrub typhus. The primary aim of this study was to identify specific epidemiological and geographical factors associated with an increased risk of developing scrub typhus in this region. We mapped 709 patients from Tamil Nadu, Andhra Pradesh and Telangana who were admitted to the Christian Medical College (CMC) Hospital, Vellore, Tamil Nadu, India, for the period 2006-2011, assessed seasonality using monthly counts of scrub typhus cases, and conducted a case-control study among a subset of patients residing in Vellore. The geographic distribution of cases at CMC Hospital clusters around the Tamil Nadu-Andhra Pradesh border. However, distinct hotspots clearly exist distal to this area, near Madurai and the coast in Tamil Nadu, and in the Northeast of Andhra Pradesh. Seasonally, the highest numbers of cases were observed in the cooler months of the year, i.e. September to January. In the case-control analysis, cases were more likely to be agricultural laborers (OR 1.79, 95% CI 1.01 - 3.15), not wear a shirt at home (OR 4.23, 95% CI 1.12 - 16.3), live in houses adjacent to bushes or shrubs (OR 1.95, 95% CI 1.08 - 3.53), and live in a single room home (OR 1.75, 95% CI 1.02 - 3.01). On binary logistic regression, the first three of these variables were statistically significant. With the growing number of cases detected in India, scrub typhus is fast emerging as a public health threat and further research to protect the population from this deadly infection is essential. Health education campaigns focusing on the agricultural workers of Southern India, especially during the cooler months of the year, can serve as an important public health measure to control infection.

    A total 494 cases of AIDS had been reported to the Ministry of Health and Family Welfare in India by October 31, 1993. Tamil Nadu and Maharashtra have the highest number of cases at 152 and 117 respectively, Kerala has 76, Punjab/Chandigarh 47, and Delhi 42, while the other states reported 1-17. More than 90% of cases were in the 15-45 year-old age group. Multipartner sex probably accounts for 80% of infections, blood and blood product transfusions for 12%, and sharing unsterilized drug injecting equipment for 5%. This number of reported cases, however, represents only a small fraction of actual AIDS morbidity in India due to general underreporting; the actual number of AIDS cases is probably in the range of 10,000-20,000 thousand. As for HIV infection, 13,448 of the 1,933,834 individuals tested for HIV through the nationwide surveillance network over the period October 1985-October 1993, were found to be infected. The seropositivity rate increased from 2.5/1000 in 1986 to 11.2/1000 by 1992. The author notes, however, that up to 90% of the population groups screened thus far came from high-risk groups. HIV-infected individuals were found in almost all states and Union Territories, although the major concentration of HIV remains in Bombay which may contain 5-10% of the country's infected individuals. Surveillance reports from the commercial sex workers show a marked rise in HIV prevalence from 10% in 1986 to 32% in 1991. Other hot spots are Pune, Madras, Madurai, and Vellore. The latest studies have shown HIV infection among IV drug users to be 74% in Manipur, 50% in Nagaland, and 6-10% in Mizoram. More than 1.5 million people were estimated to have been infected by the end of 1993. Lack of information from rural and semi-urban areas, however, does not allow estimates and projections beyond the major municipal centers. The author warns that current conditions of HIV infection and AIDS in India strongly resemble those in certain regions of Africa in the 1980s after

    Full Text Available Background & objectives: Rapid diagnostic tests (RDTs have become an essential surveillance tool in the malaria control programme in India. The current study aimed to assess the performance of ParaHIT-f, a rapid test in diagnosis of Plasmodium falciparum infection through detecting its specific antigen, histidine rich protein 2 (PfHRP-2, in Odisha State, India. Methods: The study was undertaken in eight falciparum malaria endemic southern districts of Odisha State. Febrile patients included through active case detection, were diagnosed by Accredited Social Health Activists (ASHAs for P. falciparum infection using the RDT, ParaHIT-f. The performance of ParaHIT-f was evaluated using microscopy as the gold standard. Results: A total of 1030 febrile patients were screened by both microscopy and the RDT for P. falciparum infection. The sensitivity of ParaHIT-f was 63.6% (95% CI: 56.0-70.6 and specificity was 98.9% (95% CI: 97.9-99.5, with positive and negative predictive values (PPV and NPV of 92.6% (95% CI: 86.0-96.3 and 93.0% (95% CI: 91.0-94.5, respectively. When related to parasitaemia, the RDT sensitivity was 47.8% at the low parasitaemia of 4 to 40 parasites/µl of blood. Interpretation & conclusions: The results showed that the performance of the RDT, ParaHIT-f, was not as sensitive as microscopy in detecting true falciparum infections; a high specificity presented a low frequency of false-positive RDT results. t0 he sensitivity of ParaHIT-f was around 60 per cent. It is, therefore, essential to improve the efficiency (sensitivity of the kit so that the true falciparum infections will not be missed especially in areas where P. falciparum has been the predominant species causing cerebral malaria.

    Full Text Available Over 1.1 billion people worldwide are at risk for lymphatic filariasis (LF, and the global burden of LF-associated lymphedema is estimated at 16 million affected people, yet country-specific estimates are poor.A house-to-house morbidity census was conducted to assess the burden and severity of lymphedema in a population of 1,298,576 persons living in the LF-endemic district of Khurda in Odisha State, India. The burden of lymphedema in Khurda is widespread geographically, and 1.3% (17,036 of the total population report lymphedema. 51.3% of the patients reporting lymphedema were female, mean age 49.4 years (1-99. Early lymphedema (Dreyer stages 1 & 2 was reported in two-thirds of the patients. Poisson regression analysis was conducted in order to determine risk factors for advanced lymphedema (Dreyer stages 4-7. Increasing age was significantly associated with advanced lymphedema, and persons 70 years and older had a prevalence three times greater than individuals ages 15-29 (aPR: 3.21, 95% CI 2.45, 4.21. The number of adenolymphangitis (ADL episodes reported in the previous year was also significantly associated with advanced lymphedema (aPR 4.65, 95% CI 2.97-7.30. This analysis is one of the first to look at potential risk factors for advanced lymphedema using morbidity census data from an entire district in Odisha State, India.These data highlight the magnitude of lymphedema in LF-endemic areas and emphasize the need to develop robust estimates of numbers of individuals with lymphedema in order to identify the extent of lymphedema management services needed in these regions.

  18. Searching for Comparative International Water Research: Urban and Rural Water Conservation Research in India and the United States

    2014-02-01

    Full Text Available Comparison is common in water management research: every table, map, and graph invites comparisons of different places and variables. Detailed international comparisons, however, seem infrequent in water resources research. To assess this perceived gap, this paper searched for examples of comparative research between two water sub-sectors in two countries using systematic bibliographic mapping procedures. It focused on rural and urban water conservation research in India and the United States. Search methods built upon procedures initially developed for the FAO Investment Centre and more advanced systematic review methods. The search generally confirmed that there have been few detailed comparative international studies on the subject of this review. Not surprisingly, there are a greater number of comparative studies between rural and urban water conservation within each country. The search also identified different conservation emphases in the two countries, e.g., rainwater harvesting in India compared with stormwater quality management in the United States. It identified unanticipated publications and l¬ines of comparative water conservation (e.g. comparative physiology. Some transnational research goes beyond comparison to address the diffusion of innovations, i.e. research linkages as well as comparisons, although these studies are also few. The more prevalent pattern involves parallel literatures, which indicate substantial opportunities for future comparative and transnational research. This review also identified diffusion of international knowledge paths that are not the product of formal comparative research. The final section focuses on the prospects and priorities for future international and inter-sectoral research, e.g. paired multi-objective river basin research, linkages between climate change adaptation and disaster risk reduction, diffusion of water conservation innovations, and synthesis of research on urban and rural

    Full Text Available Concerned over the lack of high quality, context specific management research in India, and the predilection of Indian researchers to follow Western models of research and publication blindly, the authors take stock of Indian management research in this round table discussion and debate some of the relevant issues. Urging Indian researchers to strive for the levels of rigour of the Western models, they make a case for confident indigenous scholarship to suit the development and educational requirements of the country, following context-relevant constructs and methodologies in research and developing curricula, materials and modes of dissemination independently. These ideas were also explored at the second Indian Academy of Management Conference held at IIM Bangalore in December 2011.

    Twenty-two taxa of Western Ghats plants were screened as potential alternative crops for renewable energy, oil, hydrocarbon and phytochemicals. The highest hydrocarbon yields were observed in Carissa carandas (1.7%), and Jatropha gossypifolia (1.7%). The highest polyphenol fraction was observed in Dodonaea viscosa (17.1%), Carissa carandas (7.7%), Swietenia mahagoni (6.6%), and Jatropha glandulifera (6.2%). The highest oil content was observed in Aganosma cymosa (10.3%), Carissa carandas (5.8%), and Argemone mexicana (5.0%). Swietenia mahagoni yielded the highest protein content with 8.1%. The gross heat value of 4175.0 cal/g(17.5 MJ/kg) for Lochnera rosea (pink flowered var.), and 4112.0 cal/g for Dalbergia sissoo were the highest among the species analysed. NMR spectra of the hydrocarbon fractions of Alstonia scholaris, Carissa carandas, Ichnocarpus frutescens, Plumeria rubra, Thevetia neriifolia (white flowered var.), Vallaris solanacea, Lochnera rosea (pink flowered var.), Euphorbia hirta, E. splendens, Artocarpus integrifolia and Ficus religiosa revealed the presence of cis-polyisoprene (natural rubber), whereas Argemone mexicana showed the presence of trans-polyisoprene (gutta). Several new crop species were identified with potentially useful compounds. The potential exists for growing these alternate crops in areas of under-utilized lands, subsequently stimulating industrial and economic growth. (author)

    In this study, results of GPR profiling related to mapping of subsurface sedimentary layers at tsunami affected Karaikal beach are presented. A 400 MHz antenna was used for profiling along 262 m stretch of transect from beach to backshore areas with penetration of about 2.0 m depth (50 ns two-way travel time). The velocity analysis was carried out to estimate the depth information along the GPR profile. Based on the significant changes in the reflection amplitude, three different zones are marked and the upper zone is noticed with less moisture compared to other two (saturated) zones. The water table is noticed to vary from 0.5 to 0.75 m depth (12–15 ns) as moving away from the coastline. Buried erosional surface is observed at 1.5 m depth (40–42 ns), which represents the limit up to which the extreme event acted upon. In other words, it is the depth to which the tsunami sediments have been piled up to about 1.5 m thickness. Three field test pits were made along the transect and sedimentary sequences were recorded. The sand layers, especially, heavy mineral layers, recorded in the test pits indicate a positive correlation with the amplitude and velocity changes in the GPR profile. Such interpretation seems to be difficult in the middle zone due to its water saturation condition. But it is fairly clear in the lower zone located just below the erosional surface where the strata is comparatively more compact. The inferences from the GPR profile thus provide a lucid insight to the subsurface sediment sequences of the tsunami sediments in the Karaikal beach.

    Water samples were collected from different formations of Gadilam river basin and analyzed to assess the major ion chemistry and suitability of water for domestic and drinking purposes. Chemical parameters of groundwater such as pH, electrical conductivity (EC), total dissolved solids (TDS), Sodium (Na+), Potassium (K+), Calcium (Ca+), Magnesium (Mg+), Bicarbonate (HCO$_{3}^{-}$), Sulphate (SO$_{4}^-$), Phosphate (PO$_{4}^{-}$) and Silica (H4SiO4) were determined. The geochemical study of the aquatic systems of the Gadilam river basin show that the groundwater is near-acidic to alkaline and mostly oxidizing in nature. Higher concentration of Sodium and Chloride indicates leaching of secondary salts and anthropogenic impact by industry and salt water intrusion. Spatial distribution of EC indicates anthropogenic impact in the downstream side of the basin. The concentration levels of trace metals such as Iron (Fe), Lead (Pb), Nickel (Ni), Bromide (Br), Iodide (I) and Aluminium (Al) have been compared with the world standard. Interpretation of data shows that some trace metals such as Al, Ni and Pb exceed the acceptable limit of world standard. Geophysical study was carried out to identify the weathered zone in the hard rock and contaminated zone by anthropogenic impact in the downstream of river Gadilam. A few of the groundwater samples in the study area were found to be unsuitable for domestic and drinking purposes.

    The present study was carried out to find the groundwater quality of coastal aquifer along Manavalakurichi coast. For this study, a total of 30 groundwater samples were collected randomly from open wells and borewells. The concentration of major ions and other geochemical parameters in the groundwater were analyzed in the laboratory by adopting standard procedures suggested by the American Public Health Association. The order of the dominant cations in the study area was found to be Na+ > Ca2+ > Mg2+ > K+, whereas the sequence of dominant anions was {{Cl}}^{ - } > {{HCO}}3^{ - } > {{SO}}4^{2 - } . The hydrogeochemical facies of the groundwater samples were studied by constructing piper trilinear diagram which revealed the evidence of saltwater intrusion into the study area. The obtained geochemical parameters were compared with the standard permissible limits suggested by the World Health Organization and Indian Standard Institution to determine the drinking water quality in the study area. The analysis suggests that the groundwater from the wells W25 and W26 is unsuitable for drinking. The suitability of groundwater for irrigation was studied by calculating percent sodium, sodium absorption ratio and residual sodium carbonate values. The Wilcox and USSL plots were also prepared. It was found that the groundwater from the stations W1, W25 and W26 is unfit for irrigation. The Gibbs plots were also sketched to study the mechanisms controlling the geochemical composition of groundwater in the study area.

    A low- to high-grade transition area in Dharmapuri district was investigated petrologically and geochemically. The investigation confirmed the presence of a continuous section through a former lower crust, with felsic charnockites predominating the lower part and felsic gneisses the upper part. The structure of original gneisses is preserved in charnockites and the latter show petrographic evidence for prograde metamorphism. The prograde metamorphism is of isochemical nature as revealed by the similarity of compositions of tonalitic gneisses and tonalitic charnockites. However, the depletion of LIL elements particularly Rb, caused variation in K/Rb ratios from low values (345) in the gneisses in upper part to higher values (1775) in the charnockites in the lower crust. This variation in K/Rb ratio in a north to south traverse is related to the progressive break-down of hydrous minerals under decreasing H2O and increasing CO2 fluid conditions. Metasomatism and partial melting has also taken place to a limited extent along shear planes and weak zones. During cooling the H2O circulation affected substantial auto-regression in the transition zone resulting in the formation of second generation biotite.

    The fluoride contamination in drinking water is already gone to the alarming level and it needs the immediate involvement and attention of all people to solve this problem. Fluoride problem is higher in hard rock terrains in worldwide and Madurai is such type of hard rock region. Totally 54 samples were collected from the Madurai district of Tamilnadu with respect to lithology. The samples collected were analysed for major cations and anions using standard procedures. The higher concentration of fluoride is noted in the Charnockite rock types of northern part of the study area. 20 % of samples are below 0.5 ppm and 6 % of samples are above 1.5 ppm exceeding the permissible limit. The affinity between the pH and fluoride ions in groundwater suggests that dissolution of fluoride bearing minerals in groundwater. The higher concentration of fluoride ions are observed in the lower EC concentration. The isotopic study suggests that fluoride is geogenic in nature. In factor scores, fluoride is noted in association with pH which indicates the dissolution process.

    The Nilgiris district in Tamilnadu has a rich biodiversity in terms of flora, fauna and ethnic population. The district is basically a mountainous region, situated at an elevation of 2000 to 2,600 meters above MSL and constituting of several hill and Steep Mountain valleys. This region houses six tribes who are mainly forest dwellers and live in close settlements depending on the forest resources for their livelihood. The Tribes of Nilgiris have been diagnosed and monitored for Sickle cell Anemia which is a disease of major concern among these ethnic populations. This genetic disorder developed due to the sickling of Red Blood Cells has increased during the past few decades. The Tribes, as they live in close encounter with the forest regions and have strict social cultural barriers, face difficulty in availing treatment or counseling from the Sickle Cell Research Center (SCRC) and other NGOs like NAWA and AHWINI in the region. It was observed that many factors such as landscape terrain, climatic conditions and improper roads tend to hinder the access to appropriate health care. The SCRC in Gudalur region is a facility established to monitor the disease cases inspite of these influencing factors. On analyzing the year bound age wise classification among male and female patients, certain dropouts in cases were observed which may be due to inaccessible condition or migration of the patient. In our study, Landscape heterogeneity mapping for different climatic seasons was done in ArcGIS 10.1. For this, contour and terrain maps, road networks and villages were prepared and factors that determine Terrain Difficulty were assessed. Vegetation mapping using IRS satellite images for the study region was attempted and associated with the landscape map. A risk analysis was proposed based on terrain difficulty and access to the nearest Health care Center. Based on this, the above factors alternate routes were suggested to access the difficult areas.

    Objective: To evaluate the antibacterial activity of Gracilaria verrucosa (G. verrucosa) (Hudson),Hypnea musciformis falk, Gracilaria ferugosoni (G. ferugosoni), Gelidium species and G. verrucosa var. against the selected bacterial pathogens. Methods: The antibacterial activities of methanol and aqueous hot extracts were tested against various organisms by using disc diffusion method. Results:The highest antibacterial activity (13 mm) was shown by the aqueous extract of G. verrucosa var. against Pseudomonas aeruginosa (P. aeruginosa) and the lowest activity (6 mm) was observed in the methanol extract of E. prolifera against Escherichia coli (E. coli). However in most of the seaweeds, methanol extract was found to be more effective. The microbial strains Salmonella typhi (S. typhi), Staphylococcus aureus (S. aureus), Bacillus subtilis (B. subtilis) and Candida albicans(C. albicans) were resistant to the aqueous extracts of all seaweeds. Conclusion: Further (H. musciformis) (Wulf) Lamour, Enatiocladia prolifera (E. prolifera) (Grev.) work is needed to identify the principle compound which is responsible for antibacterial activity against pathogenic bacteria especially those causing the human diseases.

    The natural radioactivity of soils at Yelagiri hills has been studied in this paper. The radioactivities of 25 samples have been measured with a NaI(Tl) detector. The radioactivity concentrations of 238U, 232Th and 40K ranged from ≤2.17 to 53.23, 13.54 to 89.89 and from 625.09 to 2207.3 Bq kg-1, respectively. The measured activity concentrations for these radionuclides were compared with world average activity of soil. The average activity concentration of 232Th in the present study is 1.19 times higher than world median value while the activity of 238U and 40K is found to be lower. In order to evaluate the radiological hazard of the natural radioactivity, the radium equivalent activity Raeq, the absorbed dose rate DR, the annual effective dose rate and the external hazard index (Hex) have been calculated and compared with the internationally approved values. The study provides background radioactivity concentrations in Yelagiri hills.
