Analysis of Limiters for ADITYA Tokamak

ADITYA Tokamak is a medium size ohmically heated tokamak. The hot plasma interacts with the vacuum vessel wall introducing impurities in the plasma and also damages the vacuum vessel wall. Limiter is used to reduce plasma - wall interaction and protect the vacuum vessel wall as well as inside components. It also controls impurity generation. ADITYA has a set of two types of limiters (i) Safety limiter (ii) a Poloidal limiter. Formally all the limiters are made of shaped graphite tiles fixed on stainless steel base plates. But graphite tiles are responsible for low Z impurities in plasma. To avoid these low Z impurities Molybdenum tiles are suggested. In this paper, we are going to present ansys analysis of surface temperature rise of molybdenum tiles compared to graphite tiles when used as Poloidal Limiter during plasma discharges in Aditya tokamak. The analysis is carried by ANSYS 11.0 software using Transient Thermal Analysis module. The results are compared with experimental results for graphite tiles. The graphite and molybdenum tiles are analyzed under same conditions

Large quantum gravity effects: Unexpected limitations of the classical theory

3-dimensional gravity coupled to Maxwell (or Klein-Gordon) fields is exactly soluble under the assumption of axi-symmetry. The solution is used to probe several quantum gravity issues. In particular, it is shown that the quantum fluctuations in the geometry are large unless the number and frequency of photons satisfy the inequality $\N(\hbar G\omega)^2 << 1$. Thus, even when there is a single photon of Planckian frequency, the quantum uncertainties in the metric are significant. Results hold also for a sector of the 4-dimensional theory (consisting of Einstein Rosen gravitational waves).Comment: 8 pages, No figures, ReVTe

Impact and Awareness of Soil Health Card on Soybean Production Technology in Ujjain block of Ujjain District, M.P, India

The SHC is a simple document, which contains useful data on soil based on chemical analysis of the soil to describe soil health in terms of its nutrient availability and its physical and chemical properties. The SHC is a simple document, which contains useful data on soil based on chemical analysis of the soil to describe soil health in terms of its nutrient availability and its physical and chemical properties. An amount of Rs 568 crore (US$89 million) was allocated by the government for the scheme. In 2016 Union budget of India,100 crore (US$16 million) had been allocated to states for making soil health cards and set up labs. The target for 2015–16 was to collect 100 lakh soil samples and test these for issue of soil health cards. The government plans to distribute 14 crore soil health cards by 2017. it is therefore, important to find out the impact and awareness associated with farmer towards the usefulness and application of Soil Health Card on their agricultural production, diversification and cropping pattern. Considering the above points, an effort will be made to conduct study with the following objective with 120 beneficiaries of KVK Ujjain, M.P. The main findings is majority of beneficiaries were found to have high level of awareness about various components of soybean production technology followed by medium and low level of awareness about various components of Soybean production technology. Introduction Soil is one of the elements required for farming as it provides nutrients to the plants. Healthy soil containing all the elements for growth and development of crop and on the other hand soil deprived of one or more elements either reduces production or degrades quality of crops. Proportion and quantity of macro and micro nutrients refers to the soil health. As far as agriculture production is concerned, soil health plays a vital role in ensuring sustainable production with optimizing the utilization of fertilizers and reducing its wastage. Soil Health Card (SHC) is a scheme launched by the Government of India in February 2015 in Gujarat. The SHC is a simple document, which contains useful data on soil based on chemical analysis of the soil to describe soil health in terms of its nutrient availability and its physical and chemical properties. status of farmers. Madhya Pradesh is known as the Soybean bowl of India, because major chunk of Soybean production is contributed by Madhya Pradesh State alone. Nutrients are essential for plants' growth and development. When soil nutrients are missing or in short supply, plants suffer from nutrient deficiency and stop growing. Then, application of fertilizers to soils as per requirement is very important to provide balanced nutrients to the plants grown on it. Considering the growing importance of soil testing

Antimicrobial, Antioxidative and Antilymphoproliferative Activity of a New Protein (INDIN-SAA) Isolated from Roots of Boerhaavia diffusa (Punarnava) against Scrofula adenitis (Anjeerbal)

The aim of this present study was to investigate the antimicrobial, antioxidative and antilymphoproliferative activity of the isolated new INDIN-SAA protein from the roots of B. diffusa against the disease scrofula adenitis caused by Mycobacterium scrofulaceum. Total antioxidant capacity assay showed that purified protein fraction (PPF) show stronger antioxidant activity (3.15 fold vs CPE-1.34 fold vs PPPE), than partially purified protein fraction (PPPF) and crude protein extract (CPE), respectively. The antimicrobial activity of the isolated CPEs and its PPFs on the pathogen M. scrofulaceum was evaluated on the basis of inhibition zone (IZ) using hole diffusion method, the minimal inhibitory concentration (MIC) and bacterial growth curve inhibition. The data showed that significant antimicrobial and antioxidative effect of the crude protein and its purified fractions against microorganism (M. scrofulaceum). Thus the result of this study could provide efficacious and cost effective treatment of the disease (Scrofula adenitis) without any cytotoxic effects

Effect of Psoralea corylifolia on dexamethasone-induced insulin resistance in mice

AbstractThe whole plant of Psoralea corylifolia (PC) is traditionally used in the treatment of diabetes. Mice were treated with prestandardised dose of dexamethasone for 22days and effect of PC at the doses of 100, 200 and 300mg/kg, p.o. on plasma blood glucose level, serum triglyceride level, glucose uptake in skeletal muscle, levels of hepatic antioxidant enzymes (GSH, SOD, catalase and LPO), and body weight were observed. PC showed significant decrease in plasma glucose and serum triglyceride levels (p<0.01) at the dose of 100 and 200mg/kg, p.o. and also stimulated glucose uptake in skeletal muscle. The levels of antioxidant enzymes GSH, SOD, and catalase were significantly increased (p<0.01) and there was significant decrease (p<0.01) in level of LPO.Hence it can be concluded that Psoralea carylifolia may prove to be effective in the treatment of Type-II Diabetes mellitus owing to its ability to decrease insulin resistance

Intense blue-emitting Ca5Al8O14 : Eu phosphor for mercury free lamp

The calcium aluminates doped with Eu ions, Ca5Al8O14 : Eu, phosphors are prepared by the combustion method. The formation of crystalline aluminates was confirmed by X-ray diffraction pattern. The prepared phosphors were characterized by SEM, TGA, DTA, particle size analyzer and Photoluminescence (PL) techniques. From the UV-excited luminescence spectra it was found that the Eu ions acts as a luminescent centre with luminescence at the blue (λmax = 470 nm) region due to 4f 65d1 → 4f 7 transition. The excitation spectra show the broad band at 355 nm wavelength (λem = 470 nm). The excitation 355 nm is a mercury free excitation and therefore Ca5Al8O14 : Eu may be useful for the solid state lighting phosphor in lamp industry.Intense blue-emitting Ca5Al8O14 : Eu phosphor for mercury free lamp Abhay D Deshmukh1*, S J Dhoble1, S V Godbole2, M K Bhide2 and D R Peshwe3 1Kamla Nehru College, Sakkardara Square, Nagpur-440 009, Maharashtra, India 2Spectroscopy Section, Radiochemistry Division, Bhabha Atomic Research Centre, Mumbai-400 085, India 3Department of Metallurgical and Materials Engineering, VNIT, Nagpur-440 011, Maharashtra, India E-mail : [email protected] Nehru College, Sakkardara Square, Nagpur-440 009, Maharashtra, India 2Spectroscopy Section, Radiochemistry Division, Bhabha Atomic Research Centre, Mumbai-400 085, India 3Department of Metallurgical and Materials Engineering, VNIT, Nagpur-440 011, Maharashtra, Indi

Laws Governing Isolated Horizons: Inclusion of Dilaton Couplings

Mechanics of non-rotating black holes was recently generalized by replacing the static event horizons used in standard treatments with `isolated horizons.' This framework is extended to incorporate dilaton couplings. Since there can be gravitational and matter radiation outside isolated horizons, now the fundamental parameters of the horizon, used in mechanics, must be defined using only the local structure of the horizon, without reference to infinity. This task is accomplished and the zeroth and first laws are established. To complement the previous work, the entire discussion is formulated tensorially, without any reference to spinors.Comment: Some typos corrected, references updated.

Phonon dispersion and lifetimes in MgB2

We measure phonon dispersion and linewidth in a single crystal of MgB_2 along the Gamma-A, Gamma-M and A-L directions using inelastic X-Ray scattering. We use Density Functional Theory to compute the effect of both electron-phonon coupling and anharmonicity on the linewidth, obtaining excellent agreement with experiment. Anomalous broadening of the E_2g phonon mode is found all along Gamma-A. The dominant contribution to the linewidth is always the electron-phonon coupling.Comment: 4 pages, 3 figure
