Measurement of the Bottom-Strange Meson Mixing Phase in the Full CDF Data Set

We report a measurement of the bottom-strange meson mixing phase \beta_s using the time evolution of B0_s -> J/\psi (->\mu+\mu-) \phi (-> K+ K-) decays in which the quark-flavor content of the bottom-strange meson is identified at production. This measurement uses the full data set of proton-antiproton collisions at sqrt(s)= 1.96 TeV collected by the Collider Detector experiment at the Fermilab Tevatron, corresponding to 9.6 fb-1 of integrated luminosity. We report confidence regions in the two-dimensional space of \beta_s and the B0_s decay-width difference \Delta\Gamma_s, and measure \beta_s in [-\pi/2, -1.51] U [-0.06, 0.30] U [1.26, \pi/2] at the 68% confidence level, in agreement with the standard model expectation. Assuming the standard model value of \beta_s, we also determine \Delta\Gamma_s = 0.068 +- 0.026 (stat) +- 0.009 (syst) ps-1 and the mean B0_s lifetime, \tau_s = 1.528 +- 0.019 (stat) +- 0.009 (syst) ps, which are consistent and competitive with determinations by other experiments.Comment: 8 pages, 2 figures, Phys.

Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

Selection of Optimum Sizes of Agricultural Machinery A Case Study

Selection of proper size of farm power and machinery is an important component of any farm enterprise. The decision for a particular size is very critical not only because of the high proportion of total cost attributed to machinery but also due to the infrequency and irrevocability of such decisions. Computer-based least cost mathematical models were developed for the selection of power and machinery system for paddy-wheat crop rotation practiced in Kamal district of Haryana State in India. The input data required for the models were collected through sample survey of the study area. The outputs of the model were compared with different categories of farmers. It was found that there was no significant difference between the actual farm compliments and the prediction of the model

Not AvailableIn India and other developing countries, the role of institutional support and social connectedness among fishing communities is played by and large by conventional fishermen groups, fishermen cooperative societies, federations, etc. These organizations by their very nature and reason for existence are aimed at increasing the maximum output from the fishery resources and thereby, increasing the livelihood, income and wellbeing of their members. In India, fishing cooperative societies have been studied by very few researchers and most of these studies have focused on performance of fishing cooperatives on production, marketing and financial aspects. Fishing cooperative societies as a social organization have not adequately been studied in India. This paper reports findings from a study undertaken to assess the internal functioning of the fishing cooperative societies established and promoted under different scenarios. The study covered 58 fishing cooperative societies in three states viz. Himachal Pradesh, Madhya Pradesh and Uttar Pradesh.Not Availabl

Not AvailableThe Ganges River is one of the largest river systems in the world and sustains a rich biodiversity of fish and fishers. In recent years, a decline in fish diversity and catch has become apparent due to various anthropogenic activities in the river basin. This study analyses the current fish diversity, distribution and community structure along the longitudinal gradient of the river and evaluates the ecological integrity of the riverine stretch applying a multimetric assessment approach. One hundred forty three fish species were recorded from the river and Cyprinidae was the dominant family. The middle stretch of the river exhibited dominance of small bodied erytopic, indigenous and exotic fish species with periodic and opportunistic life history strategies with significant decline of the large bodied prized Indian major carps. A tropic shift towards dominance of carnivore catfish species is evident. Non-metric multidimensional scaling revealed greater distribution and abundance of fish species with increasing river width and depth, higher sediment organic carbon, silt and clay along the river gradient. A significant change in the catches composition was evident from 1961 to 2010 in the middle stretch of the river at Allahabad. It reflected a progressive decline in proportion of Indian major carps (IMC) and the anadromous Shad Tenualosa ilisha and a significant increase in the proportion of exotic fish Cyprinus carpio and Oreochromis niloticus which represented 43–48% of the total catch. Assessment of biotic integrity showed that 28% of sample locations in the river supported fish assemblages under acceptable conditionsNot Availabl

Not AvailableAn attempt was made to estimate the geomorphological degradation due to sedimentation ofSarda Sagar reservoir, located in Pilibhit and Udhamsingh Nagar, district of Uttar Pradash and Uttarakhand respectively. The study was conducted using multidated IRS LIISS III remote sensing data for the year 2006¬2007. Using satellite images of different seasons during 2006¬2007, a total of 45.23 million m3 volume of sedimentation was computed in ¬between the 183.704 m and 190.504m elevation. The reservoir has lost 11.72 % of the total capacity of water storage and an average rate of sedimentation was calculated as 0.26 % per year. Due to this sedimentation the new feeder channel of Sarda Sagar is choked with silt and the water flow from this channel has almost stopped. The morphology of the reservoir has been changed due to sedimentation during the period 1962 to2007. This has altered breeding ground of fishes since important indigenous fish species which need flowing water condition to perform the breeding. This study would be helpful for the planners to manage the reservoir and to assess the biological productivity.ICA

Not AvailablePresent study was carried out on Sarda Sagar reservoir to know the productivity level with in the reservoir in terms of fish production based on physico-chemical parameters of water using remote sensing data. The reservoir has an average water spread area of 4590 hectares, which was computed through remote sensing data of satellite IRS- IC LISS III for the year 2006-2007. Thematic maps of distribution of individual physicochemical parameter of water were prepared using interpolation technique. Criteria based modeling was carried out for optimum range of physico-chemical properties of water those are related to the productivity, decided by the several workers. The modeling intern output of the productive zone an area of 2481 hectare (54%) falls in medium productive and 2109 hectare (46%) of area was found as high productive zone in the reservoir. Considering the level of productivity of reservoir in terms of fish was computed that was almost equal to the present fish production from the reservoir. The study may open the avenues of measuring productivity of the reservoirs for their judicious utilization of fishery resources in the Indian reservoirs.Indian Council of Agricultural Research (ICAR
