  5. Identification of groundwater discharge in Cuddalore Coast, Tamil Nadu using radium isotopes

    International Nuclear Information System (INIS)

    For the optimal exploitation and management of coastal aquifers of Tamil Nadu, it is essential to evaluate the groundwater outflow into the sea. In this study, radium isotopes (223,224Ra) were employed to understand the groundwater discharge in coastal areas of Cuddalore district, Tamil Nadu. Sea water samples (100 L) were collected from various locations of Cuddalore coast in October 2011 and passed through Mn-impregnated acrylic fiber columns. These acrylic columns were analyzed for 223,224Ra activities using Radium Delayed Coincidence Counter (RaDeCC). The observed higher activities of 223,224Ra (0-0.18 and 3.84-22.77 dpm/L respectively) indicate that groundwater discharge occurs in this coastal region. (author)

    Oral squamous cell carcinoma, the fifth most common cancer worldwide, is a major cause of morbidity and mortality in India. The effect of lifestyle factors, including tobacco chewing, smoking and alcohol drinking, diet and dental care, on the risk of oral cancer was investigated in a case-control study conducted in Rajah Muthiah Dental College and Hospital, Annamalainagar, Annamalai University, Chidambaram, Tamil Nadu, India during the period 1991-2003. The study included 388 oral squamous cell carcinoma cases and an equal number (388) of age and sex-matched controls. All participants were interviewed using a structured questionnaire that contained data on demographic factors, family history of cancer, tobacco habits, use of alcohol, frequency, duration, cessation of these habits, dietary practices and oral hygiene. The data were analysed using multiple logistic regression model. Among people with chewing habits, those who chewed betel quid with tobacco [odds ratio (OR) 3.19, 95% confidence interval (CI): 0.48-2.13] and tobacco alone (OR 2.89) showed a greater risk than controls. Bidi smoking (OR 4.63) and alcohol drinking (OR 1.65) emerged as significant risk factors for oral cancer. These three habits showed increasing risk with increasing frequency and increase in duration of habits. Addition of alcohol to other habits also enhanced the risk for oral cancer. The combination of chewing and smoking together with alcohol drinking showed very high relative risk (OR 11.34). A positive association was observed between non-vegetarian diet, poor oral hygiene and poor dentition with the risk of oral squamous cell carcinoma. The fact that these risk factors are modifiable emphasizes the need for increasing awareness among the general public and policy makers as a first step in the prevention and control of oral squamous cell carcinoma.

On the back of growing demands, due to increased construction and infrastructural activities cement market in India is expected to grow at a compound annual growth rate (CAGR) of 8.96 percent during the period 2014-2019. In this study, GIS-based spatial Multi Criteria Decision Analysis (MCDA) is used to determine the optimum and alternative sites to setup a cement plant. This technique contains a set of evaluation criteria which are quantifiable indicators of the extent to which decision objectives are realized. In intersection with available GIS (Geographical Information System) and local ancillary data, the outputs of image analysis serves as input for the multi-criteria decision making system. Moreover, the following steps were performed so as to represent the criteria in GIS layers, which underwent the GIS analysis in order to get several potential sites. Satellite imagery from LANDSAT 8 and ASTER DEM were used for the analysis. Cuddalore District in Tamil Nadu was selected as the study site as limestone mining is already being carried out in that region which meets the criteria of raw material for cement production. Several other criteria considered were land use land cover (LULC) classification (built-up area, river, forest cover, wet land, barren land, harvest land and agriculture land), slope, proximity to road, railway and drainage networks.

    The study was conducted to evaluate the suitability of ground water for irrigation purpose at twenty seven locations in Coimbatore South Taluk, Coimbatore District. The analytical result shows that Na and Cl are the dominant cation and anions respectively in the groundwater. The values of TDS and EC exceed the permissible limits at some locations due to increase in ionic concentrations. Based on SAR, RSC, US Salinity diagram and Wilcox diagram it is observed that the water ranges from excellent to good quality in most of the places and can be used for irrigation without any hazard. Gibbs variation diagram indicates that lithology is main controlling factor for water chemistry. However, the high SAR and RSC values at few locations restrict suitability for irrigation purpose.

    Full Text Available O0 bjective: The main objective of the study was to understand the perceptions of the residents of rural part of Sriperambudur Taluk, regarding areca nut use. This article discusses the findings of in-depth interviews and focus group discussions at rural part of Sriperambudur Taluk. Materials and Methods: A community-based survey was conducted using qualitative methods. Out of 168 villages, 11 were randomly chosen. Fifteen in-depth interviews and five focus group discussions were conducted. Only those above 10 years of age and who used areca nut either in processed or un-processed form were included in the study. Results: Among different forms of areca nut products, the use of Hans, which is a commercial flavored product containing areca nut, tobacco and other ingredients is believed to be the most prevalent habit in all the age groups. Chewing areca nut is the initiating habit, leading to other habits such as smoking and consuming alcoholic beverages. Residents less than 30 years of age chew areca nut products for fun or because of peer pressure whereas the 30 to 50 year olds get habituated due to reasons such as boredom and family problems. Although there is awareness regarding the ill-effects of tobacco use, there is not much awareness regarding areca nut. According to the residents, the community has not given enough thought regarding areca nut products and therefore no action has been taken to mitigate this high-risk behavior. Conclusion: It is the perception of the community that there is an increasing trend in the use of areca nut especially the commercial forms such as Hans , in rural Tamilnadu. Habit gets initiated at a very young age; therefore age specific intervention programs should be implemented. Periodic research should be conducted to better understand the changing trends of chewing areca nut products.

    Full Text Available Introduction: Tsunami struck the entire coastline of Tamil Nadu on 26 th December 2004. After tsunami an outbreak of measles was reported by media in Cuddalore district due to overcrowding of people in relief camps. We had to investigate and report within 12 hours upon this outbreak of measles and determine whether it was related to the tsunami. Materials and Methods: Investigation was done by interviewing health care workers, by visiting villages from where measles was reported and confirmed serologically among children, by looking for clustering of cases and probing for possible reasons for the outbreak. Results : By the day the investigation was carried out, 27 cases had been reported. Of these, 13 cases were from a village not affected by tsunami. There was clustering of cases in a single street in this village. Other reported cases were from villages affected by tsunami, but there was no clustering. No cases were reported from relief camps. All the affected children were above 3 years of age and were immunized previously against measles. No data were available on occurrence of measles in previous years, but it was ascertained that cases of measles occurred around the same season. No common source was identified. Interview with the health workers revealed that reconstituted vaccine was used more than 4 h after reconstitution. A faulty technique was used in route of administration in the immunization. Health workers also said that after the age of 1 year a non-immunized child was not given the vaccine. Conclusions: There was a localized outbreak of measles, but was not related to tsunami. Probable source could not be identified. Possible reasons for outbreak were the faulty use of vaccine and technique of administration. This investigation shows that though in some field situations it may not be possible, or even necessary, to carry out a full-fledged epidemiological investigation, following the epidemiological principles can lead to concrete

    The present work is employed in Omalur Taluk (study area 538.10 km(2)), Salem District, Tamil Nadu, India. Eighty-nine groundwater samples were collected during pre-monsoon (May) 2011 and were analyzed for major cations and anions. The irrigational parameters like; EC, Kelley's ratio, sodium absorption ratio (SAR) values, Mg(2+) hazards, HCO3 (-) and residual sodium carbonate (RSC) have been worked out to know the suitability of the groundwater for irrigational purpose. Wilcox diagram indicates that out of 89 samples, 39 samples belong to good permissible category and Doneen diagram revealed that 98.88 % of the groundwater samples fall in Class I. The plotting of SAR values in USSL diagram indicates that all the samples have low SAR value. Out of 89 samples, 44 samples were in C3-S1 field. This implies that no alkali hazard is anticipated to the crops. In 44 locations (49.44 %), samples fall within C3-S1 category. This category is suitable for irrigation purpose. However, the concentration of bicarbonate was in significant amount showing 82 % of sites under "increasing problem" and the 4 % sites under "Severe Problem" zones. Finally, the above-said results are taken into a Geographic Information System (GIS) platform. To understand the spatial distribution of unsuitable zones, ArcGIS was employed. The present work reveals that groundwater in the Omalur Taluk is of good quality and is suitable for all uses including interbrain water transfer in the region. PMID:23636597

    Full Text Available Groundwater samples from thirty four bore wells used for drinking and irrigation in parts of Hoskote and Malur taluks, Karnataka State (India, were collected and geochemically analysed during December 2014. The hydrochemical characteristics was dominated by Ca2+-Mg2+ -Cl--SO42- (58.82% and Ca2+-Mg2+-HCO3- (38.24%, with alkaline earth (Ca+Mg exceeding alkalies (Na+K and strong acidic anions dominating weak acidic anions. Weathering of rock-forming minerals regulated chemistry of the groundwater in the study area as indicated by Gibbs plot. The groundwater chemistry in the study area is influenced by silicate dissolution of host rock with contribution from weathering of carbonate rocks while positive CAI values indicated exchange of Na and K from the water with Mg and Ca of the rocks in the study area. The Ca2+/Mg2+ molar ratio plot further supported the fact that dissolution of calcite with effect of silicate minerals contributes calcium and magnesium to 97.06% of the groundwater. SAR, percent sodium, WQI and permeability index values demonstrated the suitability of a majority of the samples for irrigation.DOI: http://dx.doi.org/10.5755/j01.erem.71.1.9809

    Full Text Available Abstract:Education is the nourishment of the mind with knowledge this is practiced purposefully and productively. Education disciplines the mind, sharpens the intellect and refines the spirit. It's the development of integrated personality that unfolds itself to the highest wisdom. It's a continuous process. Higher education has a critical role to play particularly in the developing countries in the context of globalization and emphasis on market driven economies. Contributions of higher education to the nations' human resource development take many forms: training to middle and higher level professional, technical and managerial staff; creation of new knowledge through research and scientific study, training and dissemination, forgoing a cultural identify and fostering democratic processes by encouraging independent ideas and informed opinions.Broadly speaking, knowledge which is imparted through Higher Education provides skills to its practitioners. When discussing career options with the emphasis needs to be placed more on what they are interested in and what they enjoy rather than the job opportunities. It is at least possible that working women may also be learning valuable skills, accumulating experience, bringing in resources, establishing independence, supporting their family, enhancing their confidence and rising labour productivity. The estimated type of employment and level of education co-efficient of linear function indicated that level will increase by increasing in income.

    Full Text Available Groundwater is of most important to rural development in many countries of the world. Over exploitation of groundwater has become a major challenge not only to the present civilization and also for the future generations. The main focus of this study is to assess the suitability of groundwater quality for drinking and irrigation purposes in vicinity of Rasipuram block in Tamil Nadu. Groundwater samples from 15 locations were collected from different wells during January 2015 and analyzed for different physico-chemical parameters. The usefulness of these parameters in predicting groundwater quality characteristics were discussed. The quality of groundwater in the study area is fresh to brackish water, moderately hard to very hard in nature. The piper plot shows that the most of the groundwater samples fall in the field of Na+ -Cland mixed Ca++ -Na+ -Cltype. Water quality index rating was carried out to quantify overall groundwater quality status of the area. The WQI for these samples ranges from 37.34 to 650. Hence majority of the water samples are poor to very poor in water quality. The area in general is characterized by hard water, hence is not suitable for drinking purpose. The samples plotted in the piper and USSL diagram were used to understand the chemical characteristic of groundwater for irrigation purposes. However, the values of SAR, Na% and RSC indicate that groundwater is suitable for irrigation purposes. Overall water quality of the study area was found satisfactory for drinking purpose except in few locations and suitable for irrigation purpose. Hence the local government needs to initiate remedial measures.

    2013-01-01

    Full Text Available Context: Fluorosis is an endemic disease resulting due to excess ingestion of fluoride. Ground water has been a significant water source for domestic, irrigating, and industrial purposes in India. India is placed in a geographical fluoride belt. Kolar, a drought prone area with semiarid climate, is one among 16 fluorosis endemic districts of Karnataka. Aims: To study the prevalence of dental fluorosis among school children and to estimate the fluoride levels in drinking water sources. Settings and Design: A cross-sectional study was conducted among school-going children. Materials and Methods: School-going children from two randomly selected schools of two randomly selected Panchayat areas of Kyasamballi and Gollahalli were studied in August 2011. All the children in these schools were evaluated for dental fluorosis based on Dean′s index. Fluoride levels of drinking water sources in these communities were estimated by ion-electrode method. Statistical analysis: The data were analyzed with Epi-info 7 statistical software and expressed in proportions. Chi-square test was employed to test the significance. Results: A total of 380 children in the age group of 6-15 years were studied. The prevalence of dental fluorosis was 31.05%, predominant in females. The community fluorosis index was 0.718 indicating slight public health importances. The fluoride levels in drinking water sources exceeded 1.5 mg/L. Conclusion: Dental fluorosis is a public health problem in Kolar. High fluoride content in the sources of drinking water is the main reason for dental fluorosis, suggesting an urgent need for defluoridation of water sources with sustainable long-term measures in Kolar.

    The Lower Ponnaiyar River Basin forms an important groundwater province in South India constituted by Tertiary formations dominated by sandstones and overlain by alluvium. The region enjoyed artesian conditions 50 years back but at present frequent failure of monsoon and over exploitation is threatening the aquifer. Further, extensive agricultural and industrial activities and urbanization has resulted in the increase in demand and contamination of the aquifer. To identify the sources and quality of groundwater, water samples from 47 bore wells were collected in an area of 154 km2 and were analysed for major ions and trace metals. The results reveal that the groundwater in many places is contaminated by higher concentrations of NO3, Cl, PO4 and Fe. Four major hydrochemical facies Ca-Mg-Cl, Na-Cl, Ca-HCO3 and Na-HCO3 were identified using Piper trilinear diagram. Salinity, sodium adsorption ratio, and sodium percentage indicate that most of the groundwater samples are not suitable for irrigation as well as for domestic purposes and far from drinking water standards. The most serious pollution threat to groundwater is from nitrate ions, which are associated with sewage and fertilizers application. The present state of the quality of the lower part of Ponnaiyar River Basin is of great concern and the higher concentration of toxic metals (Fe and Ni) may entail various health hazards.

    Full Text Available Qualitative and quantitative histological alteration was taken to analyze in fish Oreochromis mossambicus collected from Kedilam River at three stations, which receive mostly industrial effluent and municipal runoff. Histoarchitecture of tissue alteration and percentage of prevalence was used as protocol for analysis. Results showed that number of histological alteration observed in gill like structural alteration of epithelium, epithelial lifting, fusion of secondary lamellae and hyperplasia. In liver blood congestion, regressive changes like degeneration of hepatocytes, vacuolation, and necrosis observed where as in kidney it shows glomerular congestion, tubular degeneration, progressive changes like hypertrophied epithelial cells, haemorrhage in bowman’s space. Among the three stations severe histological alteration and percentage prevalence was observed in order of station 1> station 2 >station 3. Highest histological alteration and percentage of prevalence in three organs of fish o. mossambicus are kidney >gill >liver. The major reason for this histological alteration and contamination of fish is mostly due to industrial effluent. Repeated and continuous monitoring is must needed to protect the aquatic organism.

  19. Groundwater recharge and quality assessment in coastal aquifers of Tamil Nadu from Cuddalore to Nagapattinam - inferences from environmental isotope study

    International Nuclear Information System (INIS)

    Ground water samples collected along the coastal tract of Tamil Nadu from different depths were measured for physicochemical parameters (electrical conductivity (EC) Temp, and pH) and environmental isotopes (18O and 3H) to evaluate their dynamics and quality. Results show groundwaters are fresh to saline and are modern. Variations in EC, δ18O and 3H indicate contribution of evaporated surface waters in the shallow zone and gradual decrease in 3H and EC and depletion in δ18O with the depth can be attributed to missing of relatively fresh, isotopically depleted and old groundwater from deeper sandstone formation.

    The study area Mettur forms an important industrial town situated NW of Salem district. The geology of the area is mainly composed of Archean crystalline metamorphic complexes. To identify the major process activated for controlling the groundwater chemistry an attempt has been made by collecting a total of 46 groundwater samples for two different seasons, viz., pre-monsoon and post-monsoon. The groundwater chemistry is dominated by silicate weathering and (Na + Mg) and (Cl + SO4) accounts of about 90% of cations and anions. The contribution of (Ca + Mg) and (Na + K) to total cations and HCO3 indicates the domination of silicate weathering as major sources for cations. The plot for Na to Cl indicates higher Cl in both seasons, derived from Anthropogenic (human) sources from fertilizer, road salt, human and animal waste, and industrial applications, minor representations of Na also indicates source from weathering of silicate-bearing minerals. The plot for Na/Cl to EC indicates Na released from silicate weathering process which is also supported by higher HCO3 values in both the seasons. Ion exchange process is also activated in the study area which is indicated by shifting to right in plot for Ca + Mg to SO4 + HCO3. The plot of Na-Cl to Ca + Mg-HCO3-SO4 confirms that Ca, Mg and Na concentrations in groundwater are derived from aquifer materials. Thermodynamic plot indicates that groundwater is in equilibrium with kaolinite, muscovite and chlorite minerals. Saturation index of silicate and carbonate minerals indicate oversaturation during pre-monsoon and undersaturation during post-monsoon, conforming dissolution and dilution process. In general, water chemistry is guided by complex weathering process, ion exchange along with influence of Cl ions from anthropogenic impact.

    We present data from three acoustic Doppler current profilers (ADCPs) moored off Cuddalore (12°N), Kakinada (16.5°N), and Gopalpur (19°N) on the continental slope of the western Bay of Bengal and one mooring on the slope of the northern bay (89°E, 19°N; referred to as being located at Paradip). The data were collected during May 2009 to March 2013 and the observations show that the seasonal cycle, which includes the annual cycle, the semi-annual cycle, and a peak around 120 days, dominates the observed variability of the East India Coastal Current (EICC). Spectral analysis suggests that the 120-day peak dominates the seasonal variability at Paradip and is strong at Gopalpur and Kakinada. The annual cycle is coherent along the western boundary of the bay, i.e., the east coast of India, but with significant phase differences between moorings. At the semi-annual and 120-day periods, the alongshore coherence is weaker. Intraseasonal variability is weaker than the seasonal cycle, particularly at Cuddalore and Paradip, and it exhibits seasonality: the strongest intraseasonal variation is during spring (February–April). Peaks around 12 and 20–22 days are also seen at Gopalpur, Kakinada, and Cuddalore. A striking feature of the currents is the upward phase propagation, but there are also instances when phase propagates downward. The much lower vertical phase speed in the top ∼100 m at Cuddalore leads to a distinct undercurrent at this location; at other locations, the undercurrent, though it exists often, is not as striking. During spring, however, the EICC tends to flow poleward (eastward) at Cuddalore, Kakinada, and Gopalpur (Paradip) over the top ∼300 m, which is the maximum depth to which observations were made. The cross-shore component of the EICC is much weaker than the alongshore component at Cuddalore and, except for a few bursts during spring, at Kakinada and Gopalpur. It is only at Paradip, on the slope of the northern boundary, that significant

    The partial pressure of Carbon-Di-oxide plays a significant role in the water chemistry. It reflects the geochemical process and relates to the saturation index (SI) of the Carbonate minerals. A total number of 98 samples were collected from layered sequential aquifers like Alluvium, Upper Cuddalore sandstone, Lower Cuddalore Sandstone and Cretaceous formations, during Pre-Monsoon and Post-Monsoon seasons. Chemical parameters of groundwater such as pH, EC, TDS, Na+, K+, Ca2+, Mg2+, Cl-, HCO{3/-}, SO{4/2-}, PO{4/3-} and H4SiO4 were determined. The study shows that an increase in the log pCO2 values during water-rock interaction which influences the process of mineral dissolution. Saturation index of the carbonate minerals like Calcite, Aragonite, Dolomite and Magnesite were derived and compared with the log pCO2 values. In both the seasons the decreasing log pCO2 increases the saturation index of most of the carbonate minerals studied. The saturation index of almost all carbonate minerals during both the seasons showed negative correlation irrespective of the formation. Log pCO2 also develops a negative correlation with pH in groundwater of the study area.

    Gadilam river basin has gained its importance due to the presence of Neyveli Lignite open cast mines and other industrial complexes. It is also due to extensive depressurization of Cuddalore aquifer, and bore wells for New Veeranam Scheme are constructed downstream of the basin. Geochemical indicators of groundwater were used to identify the chemical processes that control hydrogeochemistry. Chemical parameters of groundwater such as pH, electrical conductivity, total dissolved solids, sodium (Na(+)), potassium (K(+)), calcium (Ca(+)), magnesium (Mg(+)), bicarbonate (HCO(-)(3)), sulfate (SO(-)(4)), phosphate (PO(-)(4)), and silica (H(4)SiO(4)) were determined. Interpretation of hydrogeochemical data suggests that leaching of ions followed by weathering and anthropogenic impact controls the chemistry of the groundwater. Isotopic study reveals that recharge from meteoric source in sedimentary terrain and rock-water interaction with significant evaporation prevails in hard rock region. PMID:19609693

    Production of ceramic bricks from mixtures of ceramic industry wastes (up to 50 wt%) from the area of Vriddhachalam, Cuddalore district, Tamilnadu, India and kaolinitic clay from Thiruvananthapuram district, Kerala were investigated. The firing behavior of the ceramic mixtures was studied by determining their changes in mineralogy and basic ceramic properties such as water absorption, porosity, compressive strength and firing shrinkage at temperatures ranging from 900 to 1200 °C in short firing cycles. The effect of the rejects addition gradually up to 50 wt% was analyzed with the variation of temperature on the mechanical properties and microstructure of the bricks. The highest compressive strength and lowest water absorption is observed for the sample with 40% rejects at 1100 °C which is supported by the results of SEM analysis. The resulting ceramic bricks exhibit features that suggest possibilities of using the ceramic rejects in the conventional brick making methods. PMID:25062052

    There is a growing concern of seawater intrusion to freshwater aquifers due to groundwater overexploitation in the eastern coastal belt of Southern India. The problem becomes complex in the regions where industrial effluents are also contaminating the freshwater aquifers. In order to understand the hydrochemical complexity of the system, topographic elevation, static water level measurements, major ion chemistry, ionic cross plots, water type contours and factor analysis were applied for 144 groundwater samples of shallow and deep sources from Quaternary and Tertiary coastal aquifers, located within the industrial zone of 25 km(2) area near Cuddalore, Southern India. The ionic cross plots indicates dissolution of halite minerals from marine sources and seawater mixing into inland aquifers up to the level of 9.3%. The factor analysis explains three significant factors totaling 86.3% of cumulative sample variance which includes varying contribution from marine, industrial effluent and freshwater sources.

Methods: Cyprinus carpio procured from a local fish farm in Vadalore, Cuddalore District, Tamil Nadu, India were acclimatized under laboratory conditions for 20 d. Fish were placed into experimental tanks with 20 L of water and 22 mg/L ammonia. A total of 10 fish were collected from each experimental tank every 24 h for histopathological studies. Results:Histopathological studies showed these changes in the gills:secondary lamellar fusion, haemorrhage, oedema, epithelial hyperplasia, and chloride cell proliferation. Occasionally, multifocal necrosis of inter-lamellar regions of gill filaments but with no apparent haemorrhage was observed under electron microscopy. Conclusion:The present study shows that histopathological and ultrastructural alterations in gills are useful indicators for ammonia toxicity in Cyprinus carpio.

  14. Measurement of gamma radiation level and distribution of radionuclides in Ramanagar district of Karnataka

    International Nuclear Information System (INIS)

    Radionuclides occur naturally as trace elements in rocks, soils, building materials etc., as a consequence of the radioactive decay of uranium-238 and thorium-232. Monitoring for radioactive material is of the prime importance for environmental protection. A major contribution to the total dose of background exposure comes from primordial radionuclides such as 238U, 232Th series and 40K. If ionizing radiation affects a significant number of cells, the organism may eventually develop cancer. From the natural risk point of view, it is necessary to know the dose limits of public exposure and to measure the natural environmental radiation level provided by ground, air, water, etc for estimation of the exposure to natural radiation sources. Therefore, natural radiation levels and activity concentrations of radionuclides were carried out extensively in the environment of granite quarries of Kanakapura, Ramanagara, Channapatna Taluks and Bidadi Hobli in Ramanagara District. The indoor and outdoor gamma exposure rate in air was measured using an environmental dosemeter, and it is converted into absorbed dose using suitable conversion factor. The activity concentrations of natural radionuclides in rock samples and also in soil samples were measured using an HPGe gamma-ray spectrometer. The results reveal that the activity concentrations of 226Ra, 232Th and 40K in rocks are found to vary from 24.6 to 163.6, 70.4 to 548.6 and 387 to 1418.4 Bq kg-1, respectively. Activity concentrations of 226Ra, 232Th and 40K in soil samples were found to vary from 21.7 to 58.4, 26.3 to 214.3 and 345.8 to 1150.2 Bq kg-1, respectively. The measured values of ambient gamma dose rate in air in the outdoor and indoor atmosphere of the study area found to be varied between 21.8 and 174 nGy h-1, 147.9 and 226.2 nGy h-1, respectively. This is consistent with the geological and geo-chemical significance of the rocks of the area under investigation. The results of these systematic investigations are

    The region under investigation for groundwater exploration is a part of the eastern fringe of Deccan traps in Kalmeshwar Taluk of Nagpur district. In this region, groundwater is the main source of water supply for drinking and irrigation purposes. Presently, the known source of groundwater is the upper weathered mantle in the depth range of 8–15 m. This source of groundwater has been overexploited because of increasing demand of water supply and is unable to meet the present requirement. The present work deals with the delineation of new sources of groundwater at deeper levels concealed within and below the traps by using vertical electrical sounding surveys in order to meet the increasing demand of water supply.

    Full Text Available Abstract Background On 26 December 2004, a tsunami struck the coast of the state of Tamil Nadu, India, where one-dose measles coverage exceeded 95%. On 29 December, supplemental measles immunization activities targeted children 6 to 60 months of age in affected villages. On 30 December, Cuddalore, a tsunami-affected district in Tamil Nadu reported a cluster of measles cases. We investigated this cluster to estimate the magnitude of the problem and to propose recommendations for control. Methods We received notification of WHO-defined measles cases through stimulated passive surveillance. We collected information regarding date of onset, age, sex, vaccination status and residence. We collected samples for IgM antibodies and genotype studies. We modeled the accumulation of susceptible individuals over the time on the basis of vaccination coverage, vaccine efficacy and birth rate. Results We identified 101 measles cases and detected IgM antibodies against measles virus in eight of 11 sera. Cases were reported from tsunami-affected (n = 71 and unaffected villages (n = 30 with attack rates of 1.3 and 1.7 per 1000, respectively. 42% of cases in tsunami-affected villages had an onset date within 14 days of the tsunami. The median ages of case-patients in tsunami-affected and un-affected areas were 54 months and 60 months respectively (p = 0.471. 36% of cases from tsunami-affected areas were above 60 months of age. Phylogenetic analyses indicated that the sequences of virus belonged to genotype D8 that circulated in Tamil Nadu. Conclusion Measles virus circulated in Cuddalore district following the tsunami, although there was no association between the two events. Transmission despite high one-dose vaccination coverage pointed to the limitations of this vaccination strategy. A second opportunity for measles immunization may help reducing measles mortality and morbidity in such areas. Children from 6 month to 14 years of age must be targeted for

    Full Text Available Context: Unmet need for family planning (FP, which refers to the condition in which there is the desire to avoid or post-pone child bearing, without the use of any means of contraception, has been a core concept in the field of international population for more than three decades. Objectives: The very objective of this study is to determine the prevalence of "unmet need for FP" and its socio-demographic determinants among married reproductive age group women in Chidambaram. Materials and Methods: The study was a community-based cross-sectional study of married women of the reproductive age group, between 15 and 49 years. The sample size required was 700. The cluster sampling method was adopted. Unmarried, separated, divorced and widows were excluded. Results: The prevalence of unmet need for FP was 39%, with spacing as 12% and limiting as 27%. The major reason for unmet need for FP among the married group was 18%, for low perceived risk of pregnancy, 9%, feared the side effects of contraception 5% lacked information on contraceptives, 4% had husbands who opposed it and 3% gave medical reasons. Higher education, late marriage, more than the desired family size, poor knowledge of FP, poor informed choice in FP and poor male participation were found to be associated with high unmet need for FP. Conclusion: Unmet need for younger women was spacing of births, whereas for older women, it was a limitation of births. Efforts should be made to identify the issues in a case by case approach. Male participation in reproductive issues should be addressed.

Methods: The samples were acid digested, then analyzed by using inductively coupled plasma system (ICP-Optical Emission Spectrophotometer. Results: Levels of metals were found in the decreasing order: Cd>Co>Ni>Pb>B >Cr>Zn>Mg>Mn>Cu>Fe>Al. The soil held more levels of metals than plant parts, but within the permissible limits of concentration. Bark and root accumulated higher levels of trace elements in a magnitude of 10-80 folds than other plant parts. The overall bioaccumulation factor in the sampling sites of Vellar, Pichavaram and Cuddalore was 2.88, 1.42 0.47 respectively. Essential elements accumulate high in mature mangroves forest while non-essential elements accumulate high in the industrially polluted mangroves. Conclusions: The ratio between essential and non-essential elements was found higher in young mangrove forest than that in mature mangrove forest and polluted mangrove areas. Thus, the ratio of accumulation can be used as an index of the growth and pollution status of mangroves.

    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. PMID:26924716

    The efficacy of grass carp Ctenopharyngodon idella (Cyprinidae) and weevils Neochetina spp. (Curculionidae) to control the aquatic weed, water hyacinth, is investigated in a square net cage (happas) setting at a farm in Cuddalore District, South India. This novel combination of insects and fish is found to be superior to individual treatments for controlling the weed growth within 110 d. The biomass of the weed, number of plants, percentage of flowered plants and chlorophyll contents were studied. The weed biomass is reduced from 5 kg (day 1) to 0.33 kg (day 110) when exposed to grass carp and weevils. The number of plants is reduced to 0.75 in grass carp and weevil exposed happas, while it is 741.5 in the control. The mean number of leaves per plant is also reduced. In addition, the chlorophyll a and b are significantly reduced in happas exposed to the combination of fish and insects when compared to the other treatments. Based on the results of this study, we consider the combined use of grass carp and weevils to be more efficient and sustainable for managing water hyacinths than the use of these organisms individually.

    Full Text Available BACKGROUND Non-Steroidal Anti-Inflammatory Drugs (NSAIDs are one of the highly prescribed drugs in the world. In addition to their beneficial effect, they are having adverse reactions, of which, gastrointestinal toxicity is the most common. The reduction in NSAID-induced GI toxicity is primarily accomplished by prescribing gastro-protective agents that when co-administered with NSAIDs would protect against mucosal ulceration and the ideal candidates for co-prescription of gastro-protective agents are those considered to have a high-risk for NSAID induced ulcers. OBJECTIVES To evaluate the pattern of use of gastro-protective agents along with the anti-inflammatory and analgesics agents and to study the adverse effects in those patients receiving the anti-inflammatory agents and analgesics. METHODOLOGY A cross-sectional study done in orthopaedic outpatient departments of tertiary and secondary health centers of Thiruvananthapuram, which include totally 769 patients. The study was conducted from June 1st to September 30th 2006, after ethical clearance from the ethical committee, Government Medical College, Thiruvananthapuram. RESULTS Seven hundred and sixty nine patients were studied from three health facilities in Thiruvananthapuram District. Of the 752 cases receiving NSAIDs/analgesics in this sampling frame, Taluk hospital is receiving the highest percentage of co-prescription with gastro-protective agents (96.8%. In General hospital, 247 cases received NSAIDs/analgesics out of which 95 cases only received gastro-protective agents (38%, the lowest % among the three centers. Out of 262 cases in the MCH, 249 cases received NSAIDs/analgesics in which 193 cases received gastro protective agents (77.5 %.

    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.

    Full Text Available Water is one of the essential natural resources for the existence and development of life on the earth. The demand for water has increased over the years, and has led to a water scarcity. Ground waters are themajor resources to meet out the entire requirements. Pollution of air, water and land has an effect on the quality of the ground waters. The chemical characteristics of groundwater in Salem taluk of Salem district have been studied using Geostatistical modeling to evaluate the suitability of water for irrigation and domestic uses. The 32 water samples from PWD wells taken during the years 1999 to 2009 for post monsson and pre monsoon were tested for various chemical parameters like pH and TDS .The Geostatistical analyst of ArcGIS was used to generate voronoi maps like mean, mode, standard deviation, cluster & simple to study the spatial pattern of contamination movement for the years 1999 to 2009. Trend analysis was performed to identify trends in the input dataset. The concentrations of physical and chemical constituents in the water samples were compared with the World Health Organization (WHO standard to know the suitability of water for drinking.

    The Rural Water Supply and Sanitation (RWSS) in project and non-project villages of Mysore Taluk has been evaluated and discussed in this paper. The study area covered two villages (Yelwala and Kadakola) where Integrated Water Supply Scheme (IRWSS) was implemented under World Bank Project and two non-project villages (Belwadi and Byathahalli) closer to them. Pre and post scenarios of the project and non-project villages were investigated in terms of water quality analysis and also grading of villages has been done on the basis of water supply, sanitation, hygienic awareness and practices. Matrix methodology was used to evaluate the indicators from the survey data gathered from all studied villages. Finally, the villages were graded on the basis of cumulative value obtained for each village. Water quality analysis depicted turbidity, total dissolved solids and hardness being high and iron deficiency was also observed in water samples of all the villages. It was concluded that the present method of evaluation of rural water supply and sanitation project could be effectively applied to different upcoming projects. PMID:16649591

    International Nuclear Information System (INIS)

    Activity of the gamma emitting primordial radionuclides 238U, 232Th and 40K were measured using gamma spectroscopy with high efficiency scintillation based 4 inches x 4 inches NaI(TI) detector in environmental samples collected from various areas of Badami and Hunagund taluks of Bagalkot south district. The distribution of radionuclides and variation in activity depend upon the rock formation and the geological properties of the region. The activity of the radionuclides 238U, 232Th and 40K were found to lie in the range of 8.46 to 36.37 Bq/kg, 11.84 to 68.48 Bq/kg and 81.39 - 320.9 Bq/kg, respectively. The dose related radiological parameters were also calculated for all the samples. The observations show that the activity of the radionuclides obtained are well within the world average values and well comparable with the data of other region. The radiation hazard indices calculated showed no significant variations. Hence, the study concludes that the radiation level of the Bagalkot south district is on par with other regions of India/World. (author)

    International Nuclear Information System (INIS)

    Radon, a radioactive noble gas, daughter of 226Ra, is present in the atmosphere in large concentration compared to other radioactive elements and contribute to a major portion of the average dose received by a human from all other radiation sources. Radon, thoron and their progenies are also present in indoor and outdoor atmosphere. Their concentration in indoor atmosphere is higher than that of outdoor due to accumulation. In the present study, twin cup dosimeters with alpha sensitive films, LR-115 type-2, were used for the measurement of activities of radionuclides. The concentrations of radon, thoron and their progenies in dwellings with four different type of floorings viz. Marble, Mosaic, Cement and Granites with good and poor ventilation conditions in Tumkur district were measured. The mean inhalation doses in good and poor ventilated dwellings in all five taluks were 0.98 and 1.17 mSvy-1 respectively. The inhalation dose was found to be highest in Madhugiri with 1.10 and 1.32 mSvy-1 for good and poorly ventilated houses respectively. Also the study showed that, the concentrations of radon and thoron was more in dwellings with granite floorings. The dwelling situated near the granite rocks showed higher concentrations. (author)

    The gap in demand and supply of energy can be met by optimal allocation of energy resources. In developing countries like India, demand for energy is constantly rising. Conventional energy supply options have failed to cope up with this increase. Therefore, it is required to plan the allocation at micro-level also. A micro-level energy planning thus becomes pragmatic for sustainable development. Micro-level energy planning aims at optimal resource allocation thereby reducing dependence on commercial energy and reducing associated environmental hazards, and opening new avenues for employment generation. This paper considers energy consumption patterns in northern part of Rajasthan, India to arrive at micro-level plan using multi-objective goal programming approach. Optimal energy resource allocation for various end-uses has been deduced. In conventional micro-level energy planning the region is defined as village or taluk or district. Inter-village energy mix have been attempted to define region for energy planning in the present text. The results of inter-village mix show that the energy mix of two villages at micro-level results in better utilization of available energy sources compared to an individual village. The methodology suggested gives the flexibility of defining a region to the energy planner. (author)

  1. Groundwater dynamics of a saline impacted coastal aquifer of western Maharashtra, India. Insights from a radiotracer study

    International Nuclear Information System (INIS)

    This paper presents application of a radiotracer technique in coastal groundwater for assessing the aquifer dynamics, which is very crucial for understanding flow conditions of an aquifer and its vulnerability to salinity and other contamination. Groundwater dynamics in shallow and deep zones of Palghar Taluk located in west coast of Thane district were studied using point dilution method. 82Br in the form of NH4Br solution was used as the radiotracer and loggings were carried out by NaI (Tl) scintillation detector. From the analysis of the radiotracer activity loggings, it is found that shallow groundwater is relatively dynamic as compared to deeper groundwater at the two studied sites. The groundwater velocity is about 40-50 cm/day in the shallow zone while it is in the range of 4-40 cm/day in the deep zone. High salinity in deeper parts could be due to seawater intrusion through fractured basalt, which is diluted/flushed in the shallow zone by rain and river water. These findings are helpful in assessing groundwater dynamics in shallow and deep zones of this region and also on the impact of pumping activity on groundwater dynamics. (author)

    Detailed geological mapping in parts of Tamil Nadu and Karnataka has brought out vast areas occupied by highly deformed charnockite and high grade gneisses. These areas, similar to high grade shield terrains in other parts of the world have the impress of extensive tectonic reworking multideformation and polymetamorphism and are closely associated with layered ultramafics, shelf type sediments and different igneous events. In North Arcot and Charmapuri districts of Tamil Nadu and Kollegal taluk in Mysore district in Karnataka, charnockite is intensely cofolded with a supracrustal succession of layered ultramafics, pyroxene granulite, pink granolites, magnetite quartzite and khondalites. These areas have undergone five phases of deformation, five generations of basic dyke activities, four phases of migmatisation and two periods of metallogeny. Geochronological data ranges from 2900 m.y. to 750 m.y. In working out the tectanostratigraphy of the above areas the basic dykes of different generations have served as major time markers. In addition, the persistent strike continuity of linear bands of pyroxene granulite, pink granolite and magnetite quartzite has been of great utility in using them as structural markers for bringing out the complex structural history in these areas.

    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

    Long-term measurements of raindrop size distribution (DSD) made with the Joss-Waldvogel disdrometers at two sites (Gadanki, an inland station, and Cuddalore, a coastal station) in southeast India are utilized to study the seasonal and spatial variations of DSD. The stratified DSD data (based on rain rate R) show significant seasonal variation at both sites. Smaller-drop concentration is higher in the northeast monsoon (NEM) than in the southwest monsoon (SWM) for the same R. Paucity of smaller drops in SWM increases the mass weighted mean diameter (Dm) considerably. The seasonal differences are pronounced at Gadanki. The seasonal differences are found to be a regular feature at these locations as they are observed in all the years. The DSD has also shown clear diurnal variation with large Dm values in evening hours. The possible causative mechanisms for the observed spatial and seasonal DSD differences are investigated in detail using satellite and radiosonde observations. In particular, the research attempted to address the following question: Are the observed seasonal differences in DSD arising at the cloud formation level or related to the microphysical processes occurring in the evolution of DSD. The low-level wind pattern and cloud effective radius and Dm distributions in these seasons reveal that the cloud systems in SWM and NEM are continental and maritime, respectively, in nature. However, the microphysical and dynamical processes related to evaporation and convection also seem to play an important role in modifying the DSD. These processes are found predominantly in SWM and are, primarily, responsible for the changes in DSD during their evolution.

    To delineate the geological formation at the surface, satellite image classification approaches are often preferred. This study aims to produce a super resolved map with better delineation of the litho-contacts from the medium resolution Landsat image. Conventionally used per-pixel classification provides an output map at the same resolution of the satellite image, while the super resolved map provides the high resolution output map using the medium resolution image. In this study, four test sites are considered for delineating different litho-contacts using super resolution mapping approach in Cuddalore district, southern India. The test sites consists of charnockite, fissile hornblende-biotite gneiss, marine sandstone and sandstone with clay, limestone with calcareous shale and clay, clay with limestone bands/lenses, mio-pliocene and quaternary argillaceous and calcareous sandstone, fluvial and fluviomarine formations. This work compares the per-pixel, super resolved output derived from linear spectral unmixing (LSU) based HNN and spectral angle mapper (SAM) based HNN approaches. The super resolution mapping approach was performed on the medium resolution (30 m) Landsat image to obtain the litho-contact maps and the results are compared with the existing maps and observations from field visits. The results showed improved accuracy (90.92%) of the map prepared by the SAM based super resolution approach compared to the LSU based super resolution approach (90.14%) and the maximum likelihood classification approach (83.74%). Such an improved accuracy of the super resolved map (6 m resolution) is due to the fact that the lithological mapping is done not merely at the resolution of the image, but at the sub-pixel level. Hence, it is inferred that super resolution mapping applied to multispectral images may be preferred for mapping lithounits and litho-contacts than the conventional per-pixel and sub-pixel image classification methods.

    Full Text Available Introduction: Re-emergence of Chikungunya is a major public health problem in the southern states of India. Objectives: This study was undertaken to investigate an outbreak of Chikungunya, in June-August 2008 using PCR and determine the prevalent genotypes of Chikungunya virus (CHIKV associated with the outbreak. Materials and Methods: Samples of blood were collected (in heparinized vacutainer tubes from suspected patients of CHIKV infection from both Government Taluk Hospital in Kerala and a tertiary care hospital in Chennai, Tamil Nadu. A one-step RT-PCR was carried out on a block thermo-cycler targeting the E2 gene that codes for the viral envelope protein. The amplicons were verified for 305 bp size by standard agarose gel electrophoresis. The PCR products were purified, sequenced, and compared with other CHIKV strains reported from different geographical regions. A phylogenetic tree was constructed using MEGA 4. Results: Altogether 118 samples were collected from patients who presented with sudden onset of fever and/or joint pain, myalgia, and headache. CHIKV infection was confirmed by RT-PCR in 14 patients and all these cases were from Kerala. The positivity correlated with the early stage of the disease as all these patients had fever of less than seven days duration. The study isolates have been allotted the GenBank accession nos. GQ272368-GQ272381. Phylogenetic analysis of recent CHIKV isolates by partial sequencing of E2 region shows that isolates are closely related to strains from neighboring states and the African type. Conclusion: RT-PCR is a useful technique for the early detection of CHIKV infection during outbreaks. Molecular characterization of the strains indicates that majority of the strains have originated from the Central/East African strains of CHIKV.

    Full Text Available Phosphate fertilizers are enriched with 238U during its production from phosphate rocks. Since, application of phosphate fertilizers in modern agriculture is ever on the increase, the present study investigated the impact of phosphate fertilizers on the radioactivity profile of cultivated (fertilized soils as against virgin soils. Thirty soil samples each from cultivated fields and virgin fields were collected from Srirangam taluk and analyzed for the activity concentrations of 238U, 232Th and 40K employing gamma ray spectrometry. Similar analysis was also undertaken in commonly used phosphate fertilizers. Among the phosphate fertilizers analyzed single super phosphate (396.3 Bq/kg and triple super phosphate (284.2 Bq/kg registered higher level of 238U. The mean activity level of 238U in cultivated soil (8.4 Bq/kg was 25% higher than that of virgin soil (6.8 Bq/kg, while the mean 232Th and 40K activities in cultivated soil (98.4 Bq/kg & 436 Bq/kg were elevated by 12.4% and 4% respectively as compared to virgin soil (87.5 Bq/kg & 419 Bq/kg. The mean radium equivalent (Raeq value for virgin and cultivated soil samples was found to be 164.5 Bq/kg and 181.7 Bq/kg respectively. It is evident that the application of phosphate fertilizers elevated 238U level of the soil. However, the mean Raeq value for soil samples is well below the permissible limit of 370 Bq/kg and hence cultivated soils do not pose any radiological risk.

    Full Text Available Background: Schizophrenia is associated with excess mortality experience than the general population. Though this is one of the important outcome measures, it has not been adequately explored especially in rural community dwelling patients in India. We describe the standardized mortality ratio (SMR of a cohort of schizophrenia patients of Thirthahalli, one such rural taluk of South India. Materials and Methods: SMRs for the years 2009-2011 were calculated. A number of patients in the cohort were 301, 317, and 325 for those consecutive years, respectively. Observed deaths among the patients were noted for these years separately. Crude death rates (CDRs of the general population of Shimoga district were obtained from the Statistics Department of the Government of Karnataka. CDR (per 1000 was multiplied by the number of patients in each year to get the expected deaths. Then, observed deaths were divided by the expected deaths to get the SMR. Results: There were totally 12 deaths among the patients in these 3 years. SMRs for the years 2009, 2010, and 2011 were respectively 1.4, 1.8, and 2.2. Six had died out of natural (medical causes. Four had committed suicide, and one died from an accident. Cause from one death remained unknown. There was no statistically significant difference between the alive and deceased patients in any of the demographic or clinical variables. Conclusions: Mortality among schizophrenia patients in this rural cohort is considerably lower than patients from developed countries. Nevertheless, nearly two-fold excess mortality in schizophrenia calls for attention to their medical and psychosocial needs.

    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 BACKGROUND: Tobacco use leads to many health complications and is a risk factor for the occurrence of cardio vascular diseases, lung and oral cancers, chronic bronchitis etc. Almost 6 million people die from tobacco-related causes every year. This study was conducted to measure the prevalence of tobacco use in three different areas around Chennai city, south India. METHODS: A survey of 7510 individuals aged > = 15 years was undertaken covering Chennai city (urban, Ambattur (semi-urban and Sriperumbudur (rural taluk. Details on tobacco use were collected using a questionnaire adapted from both Global Youth Tobacco Survey and Global Adults Tobacco Survey. RESULTS: The overall prevalence of tobacco use was significantly higher in the rural (23.7% compared to semi-urban (20.9% and urban (19.4% areas (P value <0.001 Tobacco smoking prevalence was 14.3%, 13.9% and 12.4% in rural, semi-urban and urban areas respectively. The corresponding values for smokeless tobacco use were 9.5%, 7.0% and 7.0% respectively. Logistic regression analysis showed that the odds of using tobacco (with smoke or smokeless forms was significantly higher among males, older individuals, alcoholics, in rural areas and slum localities. Behavioural pattern analysis of current tobacco users led to three groups (1 those who were not reached by family or friends to advice on harmful effects (2 those who were well aware of harmful effects of tobacco and even want to quit and (3 those are exposed to second hand/passive smoking at home and outside. CONCLUSIONS: Tobacco use prevalence was significantly higher in rural areas, slum dwellers, males and older age groups in this region of south India. Women used mainly smokeless tobacco. Tobacco control programmes need to develop strategies to address the different subgroups among tobacco users. Public health facilities need to expand smoking cessation counseling services as well as provide pharmacotherapy where necessary.

In this paper an attempt has been made to study the workings of food processing units with special references to Red Chilli Cold Storage units in the Byadgi district of Karnataka State. Byadgi has been famous for Red Chilli since the days it’s of antiquity. The vast and extensive market yard in Byadagi taluk is famous as the second largest Red Chilli dealing market in the country. However, the most common and recurring problem faced by the farmer is inability to store enough red chilli from one harvest to another. Red chilli that was locally abundant for only a short period of time had to be stored against times of scarcity. In recent years, due to Oleoresin, demand for Red Chilli has grow from other countries like Sri Lanka, Bangladesh, America, Europe, Nepal, Indonesia, Mexico etc. The study reveals that all the cold storage units of the study area have been using vapour compression refrigeration system or method. All entrepreneurs have satisfied with their turnover and profit and they are in a good economic position. Even though the average turnover and profits are increased, few units have shown negligible amount of decrease in turnover and profit. This is due to the competition from increasing number of cold storages and early established units. The cold storages of the study area have been storing Red chilli, Chilli seeds, Chilli powder, Tamarind, Jeera, Dania, Turmeric, Sunflower, Zinger, Channa, Flower seeds etc,. But the 80 per cent of the each cold storage is filled by the red chilli this is due to the existence of vast and extensivered chilli market yard in the Byadgi. There is no business without problems. In the same way the entrepreneurs who are chosen for the study are facing a few problems in their business like skilled labour, technical and management

  14. Remarks at the International Conference on Human Resource Development for Introducing and Expanding Nuclear Power Programs

    International Nuclear Information System (INIS)

    Thank you and good morning, everyone. I am pleased to be in Abu Dhabi, which I have heard so much about but have never visited before. During my tenure at the U.S. Nuclear Regulatory Commission as Chairman and now as a Commissioner, I have traveled extensively across the globe in support of international nuclear safety and security and visited a number of countries. So, I can say with some experience that this is one of the most impressive examples of modern development that I have encountered anywhere in my travels. I congratulate the UAE for its commitment to national development, to this location, and to the ideal of progress toward a bright future. The topic of this conference - human resources development and the expansion of nuclear power - is about the commitment and investment in people. The importance of this 'human side' of modern technology is sometimes forgotten or assumed to develop on its own once basic educational programs and institutions are put in place. In my view, the development and maintenance of a skilled national workforce is critical to the development of a stable, successful national nuclear power program. As many of you know, I am on leave from the University of Texas and will soon be returning there. And because of my academic background, I have made the need to expand scientific and engineering education and to promote technological development a recurring theme in my numerous presentations while serving at the U.S. NRC. So I am pleased to participate in this conference today and to share the podium for this keynote address session with my distinguished and honorable colleague from India, Mr. Rajagopala Chidambaram. I also want to commend the International Atomic Energy Agency for convening this special conference on this vital subject. The subject of highly qualified, nuclear trained people has been a significant theme in my speeches and private conversations. There is little doubt that ensuring there will be enough trained and

    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. The micro water sheds are delinated identifying the ridges from Catrosat data for this interfluves basin which has mild slop. To illustrate this research, parts of two micro watersheds which were delineated using 1:50000 data for Tamil Nadu watershed Atlas up to 7th order streams are taken up for a detailed study using high resolution data. 19 Micro watersheds with streams up to 10th order are mapped.
