We conducted randomized double-blind trial for single-dose of Rifampicin, Ofloxacin and Minocycline (ROM) compared to WHO-PB-MDT among paucibacillary (PB) leprosy patients with 2-5 skin lesions. We enrolled 1526 patients from five centres (ROM=762; WHO-PB-MDT=764) and followed them for 36 months posttreatment during 1998-2003. We generated information on clearance of skin lesions and relapse rates per 100 person-years (PY) for all the five centres. At base-line, the patients in the two arms were comparable. Complete clearance of skin lesions was similar (72% vs. 72.1%; p=0.95) in both the arms. Clinical scores declined steadily and equally. Difference in relapse rates was statistically highly significant (ROM=1.13 and WHO-PB-MDT=0.35 per 100 PY; mid-p exact=0.001016). Twenty eight of 38 of these relapses occurred within 18 months. In all, 10 suspected adverse drug reactions were observed (ROM=2; WHO-PB-MDT=8). We extended the follow-up to 48 months for 1082 of 1526 patients from two programme-based centres. No further relapses occurred. Decline in clinical score was not dependent on age, gender, number of lesions or affected body parts. Single dose ROM, though less effective than the standard WHO-PB-MDT regimen conceptually offers an alternative treatment regimen for PB leprosy patients with 2-5 lesions only when careful follow-up for relapse is possible.

In view of the extensive occurrence of black granite deposits in Chittoor district, Andhra Pradesh an attempt is made in this paper to study the geology and resource evaluation of black granites for dimensional stone. Geologically the black granites are dyke rocks. The dykes are linear, tabular, vertical to sub vertical, occur in clusters and swing in their trends along strike. The petrographic studies classified the dykes of the study area into Gabbro and Dolerite dykes with quartz and micropegmatites. Geological studies have revealed that the study area samples were derived from common tholeiitic magma through variable degree of fractional crystallization. The various geological parameters that fluctuate the commercial quality and quantity of DSBG have been given special reference. The price index, resource and revenue potential, rate of recovery and other evaluation techniques are also highlighted. © 2013 CAFET-INNOVA TECHNICAL SOCIETY. All rights reserved.

The excessive exploitation of groundwater aquifers is emerging as a worldwide problem, but it is nowhere as dramatic and consequential as it is in India, the world's largest consumer, where hundreds of millions of people depend on it. Usually the problem is framed in terms of a long-term decline in water tables and its consequence for extraction costs, resource depletion, and the sustainability of irrigated agriculture. Here a comparative analysis is provided of coupled groundwater, energy, and irrigation dynamics in two groundwater intensive regions in India that differ in their underlying hydrogeologythe Indian Punjab with its deep alluvial aquifers and the Telangana region in south-central India with its shallow hard rock aquifers. Using a simple modeling framework and piezometric and agricultural time series, we show that in shallow aquifers the sense in which extraction is excessive is different, and is related to the short-term reliability of water supply rather than long-term sustainability. This has important repercussions for irrigated agricultural economies. Copyright 2011 by the American Geophysical Union.

Because of declining public investments in irrigation projects in India, the growth of irrigated agricultural production has increasingly become reliant on unsustainable allocation of groundwater. As a result, groundwater resources are increasingly depleted and their role in buffering climate variability is lost. Given future climate and food supply uncertainty under mounting population pressure, it is vital that the connections between climate variability, unsustainable irrigation practices, and their impacts on regional-scale agricultural production are quantified. Here, the focus is on rice and maize production in the semiarid Telangana region in Andhra Pradesh, where the advent of inexpensive pump technology in the late twentieth century, coupled with governmentally subsidized electricity, has allowed year-round planting of water-intensive crops. Using a 35-yr climate and agricultural dataset from Telangana, nonlinear Gaussian process district-level regression models are developed to model dry-season irrigated area, which is a proxy for total groundwater use, in the function of climate-related predictors. The resulting models are able to accurately reproduce dry-season cropped area in most districts. Interannual climate variations play a significant role in determining groundwater use for irrigation. Nonlinear interactions between selected climate features are likely to influence irrigation water use significantly. These results suggest that the authors' modeling approach, combined with monsoon predictions, allow the forecasting of cropped area and agricultural water requirements at seasonal time scales within the bounds of uncertainty. The usefulness of such data to decision makers and stakeholders is discussed, as they attempt to use scarce surface and subsurface water resources more efficiently and sustainably. © 2010 American Meteorological Society.

In this paper, a Goal Programming model was proposed for optimal deployment of patrolmen in urban areas. To demonstrate the model, we focus on Visakhapatnam city as a case study, for allocating the patrolmen to various road segments in different shifts within the patrolling region. The city road segments were divided into (a) city-link road segments; (b) intra-city road segments; and (c) by-pass road segments. In this study, different goals such as total patrolmen, minimum shift requirement, total budget, estimated accident reduction and accident rate reduction in high accident-prone areas are considered. By considering these goals, four cases are formulated to allocate the patrolmen in each road segment and to each shift. In case 1, minimization of all these goals is considered. Allocation of patrolmen in high accident-prone areas and accident rate reduction goals are minimised in case 2. Minimum shift requirement goal is considered in case 3. In case 4 total budget goal is considered. Copyright © 2011 Inderscience Enterprises Ltd.

The turn of century saw ICT technologies making inroads into our lives. The governments world over are trying to use this medium for reaching out to their citizenry. This migration has been partly driven by transparency, efficiency and wider-access related benefits accrued by automation of government functions. E-Government Procurement (E-GP) is one such area which has drawn attention of politicians and researchers equally. However, studies bring out that E-GP project like any other e-Governance project has 70% chances of failure. Studies also underline that success of any E-GP system among other things, is affected by national culture, project environment (E-Readiness, IT literacy level and technological evolution) and regulatory framework which govern public procurement in a country. Indian government having realized the transparency and efficiency related benefits of E-GP system initiated an aggressive campaign to ensure its speedier implementation through National E-Governance Programme (NeGP) which was launched in 2006. However, recent review by Government of India (GoI) brought out that E-GP usage in the country has been less than satisfactory. In above perspective, this paper aims to undertake Template Analysis of stage-wise importance of 11 Critical Success Factors (CSF) (reported in literature) in E-GP project outcome in Indian context. For covering large landscape of E-GP implementation in India, two representative systems i.e. those implemented by Government of Andhra Pradesh and National Informatics Corporation were selected. The study concludes that out of 11 CSFs, five CSFs are not important at stage 2 of E-GP project evolution, while all 11 CSFs contribute to E-GP project success at Stage 3 and 4. Copyright 2014 ACM.

In canal irrigated areas, where interactions between surface water and groundwater are high, the conjunctive management of surface water and groundwater can play a significant role in improving water availability in time and space, thereby promoting more equitable distribution of water while maintaining long-term availability of groundwater resources. Achieving a harmonious balance between the use of surface water and groundwater requires careful consideration of the associated benefits, impacts, and trade-offs. In this study, a simple, integrated framework was developed and implemented to characterize and quantify interactions between surface water and groundwater in a canal irrigated area; this framework was used to evaluate the impacts of alternative levels of conjunctive use under varying climate and cropping conditions. Applying the model to a case study area of the Srisailam Right Branch Canal project in Andhra Pradesh, India, indicated that regulating canal supplies to optimum levels can prompt sustainable groundwater use and save up to 48% of allocated canal water; these water savings could be reallocated elsewhere within the irrigated area to promote equity. © 2013 American Society of Civil Engineers.

Optimal land allocation plays a vital role for the development of agriculture sector. Development toward optimal utilization of land under cultivation and increasing the production of crops and proft with less fertilizer consumption must be taken into consideration in agriculture planning. In this paper, a weighted additive model is formulated with net proft, production of crops, and fertilizer consumption as objectives and availability of cultivable land, agriculture labour, agriculture machinery, and water as constraints for optimal land allocation. Weighted additive model takes care of relative priority of objectives laid by the agriculture planners. To illustrate the model, a case study ofVisakhapatnam district, Andhra Pradesh, India is presented. The results ofGA approach are compared with LINGO solver and observed that there is an improvement in the utilization of land. Copyright © 2010, IGI Global.

In India, groundwater assessment units are classified as overexploited areas, critical areas, semi-critical, or safe areas based on the stage of groundwater development and long-term water level trends. Intuitively, in the safe units, wells are expected to function and have good yields. Besides, in the safe units, new wells are expected to be successful. Conversely, the expectation of a successful well or wells with good yields is much lesser in the overexploited units. However, when these expectations are not met in the field, doubts are raised about the quality of assessment and its usefulness, and there is outright distrust on the agencies assessing groundwater resource by the common man as well as on the planners, administrators, and the politicians. Therefore, there is a need to present the results in a way that does not create confusion. One of the methods is to combine the assessment results with aquifer characters using geographic information system (GIS); when this is done, a whole set of newer classes emerge, which can be mapped. These classes are termed as groundwater typologies in this study. Each typology has some characteristics or traits in common, which include basic aquifer character as well as the stage of groundwater development. Thus, a class may be safe, but if the aquifer is poor, then it is separated from a class that is safe and where the aquifer is good and so on. In Andhra Pradesh, which is taken as the case study for this purpose, eight main typologies emerged, and two of these main typologies were further divided into four subtypologies each. This new way of understanding the pattern of groundwater abstraction (using GIS) has a better visual impact. Groundwater typologies are found to be much more rational and useful in developing management strategies, rather than simple listing as overexploited areas, critical areas, semi-critical areas, and safe areas as is commonly done. The typologies so delineated indicate on the map (or table) that balanced usable groundwater is in between 5 and 6bcm/a as against the estimated balance of 20.5bcm/a, and it is largely in poor hard rock type of aquifers, which occupy about a third of the area of the state.
