Rupture of Water Drops Over Liquid Surfaces

The critical height to produce rupture of water drops of different sizes over oils and their mixtures have been observed. A linear relation is found to exist between the critical height and the reciprocal of the mass of the drop for a given liquid. The variation of the critical height fur a particular size of the drop with different liquids of different viscosities, shows a distinct minima in each case of the experimental curves. The surface tension, interfacial surface tension, and density of the oils have also been measured, which may throw light on the true mechanism of the rupture of water drops

Thermodynamic Geometry of the Born-Infeld-anti-de Sitter black holes

Thermodynamic geometry is applied to the Born-Infeld-anti-de Sitter black hole (BIAdS) in the four dimensions, which is a nonlinear generalization of the Reissner-Norstr\"Aom-AdS black hole (RNAdS). We compute the Weinhold as well as the Ruppeiner scalar curvature and find that the singular points are not the same with the ones obtained using the heat capacity. Legendre-invariant metric proposed by Quevedo and the metric obtained by using the free energy as the thermodynamic potential are obtained and the corresponding scalar curvatures diverge at the Davies points.Comment: Latex,19 pages,14 figure

Rebel Health Services in South Asia: Comparing Maoist-led Conflicts in India and Nepal

This is the first paper comparing Indian and Nepali Maoist rebels providing health services and health promotion to the communities under their influence. The paper presents the key provisions either made by rebel health workers themselves or by putting political pressure on government health workers to deliver better services in the areas controlled by rebels. The paper is based on a mixed-method approach comprising 15 interviews and a questionnaire survey with 197 Nepalese Maoist health workers and a secondary analysis of policy documents and other published materials on the Maoist health services of India. The paper suggests that rebel health services in India and Nepal followed a fairly similar approach to what and how they offered health care services to local populations. Maoists becoming a government party changed the political landscape for the rebel health workers in Nepal. However, not incorporating the Maoist rebel health workers into the government health system was a missed opportunity. There are lessons that India and Nepal can learn from each other. Should the Maoist rebels and the Government of India come to an agreement, potential for rebel health workers to be integrated in the official health care system should be considered

Semi-Mechanized Harvesting Solutions for Cultivated Fodder Crops

In case of harvesting and threshing, the level of mechanization in India is 60-70 per cent for wheat and rice and less than five per cent for other crops (Mehta et al., 2014) that include fodder also. Herrmann et al.(2011) established that overall area capacities of machine decreased the by 4-24 per cent on taking finer chopping length of 4-6 mm compared to common chopping length of 8-10 mm in the ensiling chain of maize - establishing that finer work in ensiling commands less capacities and higher input costs. Since there is a strong correlation between effective field capacity and both crop yield and field area (Amiama et al., 2008), it is advisable to go for appropriate machine for fodder harvesting depending on the requirement of crop and field. Semi-automatic machines provide comparatively low cost workable solution in such conditions. In semi-mechanized harvesting of fodder, cutting of crop is done by machine and subsequent operations of collection, gathering, feeding to chaffing machines and feeding to animals are done manually. Such machines are discussed here

A Comparative Note on Tunneling in AdS and in its Boundary Matrix Dual

For charged black hole, within the grand canonical ensemble, the decay rate from thermal AdS to the black hole at a fixed high temperature increases with the chemical potential. We check that this feature is well captured by a phenomenological matrix model expected to describe its strongly coupled dual. This comparison is made by explicitly constructing the kink and bounce solutions around the de-confinement transition and evaluating the matrix model effective potential on the solutions.Comment: 1+12 pages, 9 figure

Role of plasminogen activator inhibitor type 1 (PAI-1) in PCOS patient

Background: There has been few studies done demonstrating elevated level of PAI-1 in women with Polycystic Ovarian Syndrome (PCOS). PAI-1 has been associated with insulin resistance, obesity, anovulatory infertility, increased risk of cardiovascular disease in PCOS patient. The objective of the study was to find out the plasma level of PAI-1 in PCOS and compare with healthy age matched control. To correlate PAI-1 with various demographic, anthropometric, biochemical and hormonal parameters in PCOS patient and specific relation of PAI-1 with the insulin resistance, obesity, hyperandrogenemia.Methods: A prospective case control study was carried out in 50 patients having PCOS (fulfilling Rotterdam Criteria, 2003). 25 healthy age matched control were taken. Blood samples were taken for estimation of fasting glucose, fasting insulin, lipid profile, LH, FSH, Prolactin, Testosterone, insulin sensitive indices (HOMA-IR, glucose: insulin ratio). Plasma level of PAI-1 was estimated with Human ELISA invitorgen kit. The data were statistically analysed with SPSS 16.0 version (student T test, Pearson ranked correlation coefficient, linear regression analysis was applied) and PAI-1 was correlated with various parameters.Results: Mean level of PAI-1 was significantly raised in PCOS patient (893.36±234.97) pg/mL than in control (259.68±97.75) pg/mL (p<0.001). PAI-1 significantly correlated with insulin resistance, obesity; that is; PAI-1 significantly correlated with BMI (r=0.557; p<0.001), waist: hip ratio (r=0.550; p<0.001), fasting glucose (r=0.429; p=0.002), fasting insulin (r=0.357; p=0.001), triglyceride (r=0.492; p=0.000), LDL (r=0.604; p=0.001), HOMA-IR (r=0.467; p=0.001). On regression analysis LDL, fasting insulin, HOMA-IR altogether explained 54.9% of total variability of PAI-1.Conclusions: Plasma level of PAI-1 is elevated in PCOS patient and it is significantly correlated with insulin resistance and obesity

On the Thermodynamic Geometry and Critical Phenomena of AdS Black Holes

In this paper, we study various aspects of the equilibrium thermodynamic state space geometry of AdS black holes. We first examine the Reissner-Nordstrom-AdS (RN-AdS) and the Kerr-AdS black holes. In this context, the state space scalar curvature of these black holes is analysed in various regions of their thermodynamic parameter space. This provides important new insights into the structure and significance of the scalar curvature. We further investigate critical phenomena, and the behaviour of the scalar curvature near criticality, for KN-AdS black holes in two mixed ensembles, introduced and elucidated in our earlier work arXiv:1002.2538 [hep-th]. The critical exponents are identical to those in the RN-AdS and Kerr-AdS cases in the canonical ensemble. This suggests an universality in the scaling behaviour near critical points of AdS black holes. Our results further highlight qualitative differences in the thermodynamic state space geometry for electric charge and angular momentum fluctuations of these.Comment: 1 + 37 Pages, LaTeX, includes 31 figures.

Kerr-Newman Black Hole Thermodynamical State Space: Blockwise Coordinates

A coordinate system that blockwise-simplifies the Kerr-Newman black hole's thermodynamical state space Ruppeiner metric geometry is constructed, with discussion of the limiting cases corresponding to simpler black holes. It is deduced that one of the three conformal Killing vectors of the Reissner-Nordstrom and Kerr cases (whose thermodynamical state space metrics are 2 by 2 and conformally flat) survives generalization to the Kerr-Newman case's 3 by 3 thermodynamical state space metric.Comment: 4 pages incl 2 figs.

Matching of the continuous gravitational wave in an all sky search

We investigate the matching of continuous gravitational wave (CGW) signals in an all sky search with reference to Earth based laser interferometric detectors. We consider the source location as the parameters of the signal manifold and templates corresponding to different source locations. It has been found that the matching of signals from locations in the sky that differ in their co-latitude and longitude by $\pi$ radians decreases with source frequency. We have also made an analysis with the other parameters affecting the symmetries. We observe that it may not be relevant to take care of the symmetries in the sky locations for the search of CGW from the output of LIGO-I, GEO600 and TAMA detectors.Comment: 16 pages, 7 figures, 3 Tables, To appear in Int.
