The paper estimate 1-day Value at Risk (VaR) taking into consideration the financial integration of Indian capital market (BSE-SENSEX and NSE-NIFTY) with other global indicators and its own volatility using daily returns covering the period January 2003 to December 2009. The paper specifies a generalized autoregressive conditional heteroscedasticity (GARCH) framework to model the phenomena of v...

We have investigated the effect of nicotinic receptor ligands in the behavioral sensitization (hyperlocomotion) and rewarding properties (conditioned place preference paradigm, CPP) of 3,4-methylenedioxy-methamphetamine (MDMA) in mice. Each animal received intraperitoneal pretreatment with either saline, dihydro-β-erythroidine (DHβE, 1 mg/kg) or varenicline (VAR, 0.3 mg/kg), 15 min prior to sub...

The age of stratospheric air is computed with a trajectory model, using ECMWF ERA-40 3D-Var and operational 4D-Var winds. Analysis as well as forecast data are used. In the latter case successive forecast segments are put together to get a time series of the wind fields. This is done for different forecast segment lengths. The sensitivity of the computed age to the forecast segment length and a...

Pb inhibits plant growth. To study Pb tolerance in rice (Oryza sativa), we screened 229 varieties for Pb tolerance or sensitivity. Three-day-old seedlings were treated for 12 d with 20 microM Pb solution. Based on the dry weight of the root, three Pb-tolerant (var CH-55, var KH-2J, var Kumnung) and three Pb-sensitive (var Aixueru, var C-9491, var Milyang23) rice varieties were selected. The roo...

At any point of time, a power system operating condition should be stable, meeting various operational criteria and it should also be secure in the event of any credible contingency. Present day power systems are being operated closer to their stability limits due to economic and environmental constraints. Maintaining a stable and secure operation of a power system is therefore a very important...

The succulent Kalanchoe blossfeldiana v. Poel. var Tom Thumb was treated on long and short photoperiods for 6 weeks during which short day plants developed thicker leaves, flowered prolifically, and exhibited extensive net dark fixation of carbon dioxide. In contrast, long day plants remained vegetative and did not develop thicker leaves or exhibit net carbon dioxide dark fixation. When examine...

BACKGROUND Recent circumstantial evidences are suggesting that an increasing number of Iranian patients with cutaneous leishmaniasis are unresponsive to meglumine antimoniate (Glucantime®). Pistacia atlantica is native plant in Iran (central, western, and eastern regions). Gum obtained Pistacia atlantica has been reported to possess considerable in vitro antimicrobial activity. In this study, w...

Alginate encapsulated B. thuringiensis var. israelensis (B. t. i.) self floating type formulations were prepared. Its spore release rate, floating efficacy and larvicidal activity against Culex quinquefasiatus were tested in the laboratory. The larval mortality of 91-100% was induced by the floating formulation with a mean spore release of 3.04 x 10(4)/ml/day from 6th day to 27th day. From day ...

DNA renaturation experiments gave evidence to conclude that Rhizopus arrhizus, R. OIyzae, R. delemar, Amylomyces rou.xii, R. delemar var. minimus, R. delemar var. multiplicisporus, R. arrhizus var. delemar, R. chungkuoensis var. isqfermentarius, and R. javanicus var. kawasakiensis can be accommodated in three taxa, namely, R. arrhizus var. arrhizus, R. arrhizus var. rozedi, and R. arrhizus var....

Plants of Juniperus communis L. var. communis, J. c. var. depressa Pursh, J. c. var. hemispherica J. & C. Presl, J. communis var. megistocarpa Fern. & St. John, J. c. var. nipponica (Maxim.) Wils., J. c. var. oblonga hort. ex Loudon and J. c. var. saxatilis Pall. were sampled and DNA fingerprinting (RAPDs, Random Amplified Polymorphic DNAs) was performed. Based on 191 RAPD bands, there was litt...
