A case study on Dusta Vrana (Non Healing Varicose Ulcer)
Any kind of destruction / break / rupture / discontinuity of body tissue/part of the body is called Vrana. Vrana which doesn’t heal in its natural course of healing time is said to be Dusta Vrana along with other pathological manifestations further. Acharya Susruta explains, when a person does not have control over his indriya’s and follows Apathyaja ahaar ,vihar with untimely treated wound leads to severe vitiation of Doshas forming Dushta Vrana. In classics it’s been widely explained about the chikitsa of Vrana. Considering clinical features of dusta vrana and cause here the correlated with Non healing varicose ulcer. The Chronic non healing ulcer are the ulcers that have failed to progress through a time. Sequence of repair, or one that proceeds through the wound healing process without restoring anatomic and functional results
Double-gap superconducting proximity effect in nanotubes
We theoretically explore the possibility of a superconducting proximity
effect in single-walled metallic carbon nanotubes due to the presence of a
superconducting substrate. An unconventional double-gap situation can arise in
the two bands for nanotubes of large radius wherein the tunneling is (almost)
symmetric in the two sublattices. In such a case, a proximity effect can take
place in the symmetric band below a critical experimentally-accessible Coulomb
interaction strength in the nanotube. Furthermore, due to interactions in the
nanotube, the appearance of a BCS gap in this band stabilizes superconductivity
in the other band at lower temperatures. We also discuss the scenario of highly
asymmetric tunneling and show that this case too supports double-gap
superconductivity.Comment: 4 pages, 2 figure
PC Controlled Rain Simulation
Rainfall simulators have a long history of successful use in both laboratory and field investigations. A challenge faced today is to have practical method of assessing the impact of various natural phenomena on day to day life. With the climatic change taking place globally, there is necessity to simulate rain to assess and estimate its impact on our lives. It is developed with an objective to simulate rainfall which is computer controlled hardware implemented simulation for scaled model food godown. In this paper, we describe simulation of rain practically on a scaled model. The simulator is controlled by PC which can be programmed as per the requirement of user and can be modified and adopted easily. The process of PWM is achieved using a PC which has custom developed program interfaced to drive a water delivery system through PLC and MOSFET drive.

Distribution of chlorophyll 'a' and 'b' in the eastern Arabian Sea (west coast of India) in relation to nutrients during post monsoon
The distribution of chlorophyll 'a' and 'b' in the Arabian Sea along the west coast of India from Cape Comorin to Veraval in the 40-200rn depth contour, in a single cruise of FORV Sagar Sampada (Cruise no. 177) was studied, covering 58 stations duringng the post monsoon period October-November, 1999. Data on nitrates and phosphates were also collected along with chlorophylls. The results indicated that the coastal waters along the south west coast of Inaia are more productive than the waters along the north west coast during the post monsoon period. Earlier observations on chlorophylls and nutrients from eastern Arabian Sea are briefly discussed
Thermodynamics in expanding shell-shaped Bose-Einstein condensates
Inspired by investigations of Bose-Einstein condensates (BECs) produced in the Cold Atom Laboratory (CAL) aboard the International Space Station, we present a study of thermodynamic properties of shell-shaped BECs. Within the context of a spherically symmetric bubble trap potential, we study the evolution of the system from small filled spheres to hollow, large, thin shells via the tuning of trap parameters. We analyze the bubble trap spectrum and states and track the distinct changes in spectra between radial and angular modes across the evolution. This separation of the excitation spectrum provides a basis for quantifying dimensional crossover to quasi-2D physics at a given temperature. Using the spectral data, for a range of trap parameters, we compute the critical temperature for a fixed number of particles to form a BEC. For a set of initial temperatures, we also evaluate the change in temperature that would occur in adiabatic expansion from small filled sphere to large thin shell were the trap to be dynamically tuned. We show that the system cools during this expansion but that the decrease in critical temperature occurs more rapidly, thus resulting in depletion of any initial condensate. We contrast our spectral methods with standard semiclassical treatments, which we find must be used with caution in the thin-shell limit. With regard to interactions, using energetic considerations and corroborated through Bogoliubov treatments, we demonstrate that they would be less important for thin shells due to reduced density but vortex physics would become more predominant. Finally, we apply our treatments to traps that realistically model CAL experiments and borrow from the thermodynamic insights found in the idealized bubble case during adiabatic expansion
An empirical investigation on the impact of attitudes towards organ donation in India [version 2; peer review: 2 approved]
Background: Organ shortage is a global issue and it is imperative to take steps to bridge this gap. In the Indian context, despite its demographic dividend, the rate of organ donation has been abysmally low. This emphasizes a need to demystify the antecedents of organ donation intention among the Indian population. Methods: Using a cross-sectional research design and adopting a post-positivism research philosophy, this study identified 259 respondents by adopting a purposive sampling approach and data on knowledge of organ donation was collected using a structured, pretested questionnaire. Results: Awareness of organ donation law in India is low on specific issues and respondents from the health science & medicine discipline scored better on knowledge about organ donation. The findings show that most participants had heard about organ donation and had a favourable attitude toward it. The primary sources of information on organ donation were television and newspapers, and healthcare service providers. A complementary partial median is established (β = .217, t = 5.889, p < .001) which implies that willingness to discuss with family significantly mediates the association between attitude towards organ & tissue donation and willingness to sign the donor card. Conclusion: This study revealed that there is a general awareness of organ and tissue donation among the Indian population, but they lack clarity on certain specific issues. Mass media has to be effectively used to build awareness campaigns revolving around enhancing knowledge on a specific issue and building acceptance of the concept of organ and tissue donation
