Arabian Sea Mini Warm Pool and its Influenceon Acoustic Propagation

A systematic experiment was conducted in the eastern Arabian Sea for the first time exclusivelyto study the characteristics of the Arabian Sea mini warm pool1. The analysis revealed complexnature of the thermohaline and sonic layer distributions across the Arabian Sea mini warm pool.This mini warm pool was identified between 67.5 oE and 75 oE, where the sea surface temperaturewas in excess of 30.25 oC. At the core of this mini warm pool, warmer (>31.2 oC) and low saline(<34.6 PSU) waters were noticed. Further, very thin sonic layer (< 5 m) was noticed at the miniwarm pool core, which increased eastward and westward. In this study, the acoustic propagationcharacteristics across and outside of the core, i.e., (i) within the mini warm pool core, (ii) easternside of the mini warm pool core, and (iii) western side of the mini warm pool core, were assessedbased on the output of a range-dependant acoustic model. In general, the occurrence of this miniwarm pool was found to alter the propagation characteristics. Better propagation was obtainedwhen the simulation was carried out on the eastern side of this mini warm pool, with source nearthe coast (i.e., downslope condition

Kharif Sorghum Germplasm Collection in Karnataka and Adjoining Areas

An assessment of the present world collection of sorghum maintained at ICRISAT reveals that the majority of the germplam constitute either experimental accessions which are generally photo insensitive or authentic indigenous races from tropical countries which are photosensitive. Most of the landraces assembled from tropical countries including India behave photoperiod sentitive when grown in a long day (rainy) seson at Patancheru (17 27'N latitude) indicating the lacking of early insensitive types especially from India. There are very few pockets in South India where early kharif types are cultivated among which Northern Karnataka and its adjoining areas are very important. These areas were not adequately collected in earlier missions and their valuble germplasm are facing severe threat from hybrid and improved sorghum varieties. More landraces from this region may provide valuable source material for sorghum improvement programs particularly for earliness probable resistance to drought (several areas are drought prone). They may also possess weathering resistance because of their maturity during rainy seaso

Morphological diversity in sorghum germplasm from India

Of the 5000 sorghum (Sorghum bicolor L. Monench) germplasm accessions assembled at ICRISAT Asia Center (IAC), over 4000 accessions from 11 major sorghum growing states in India were evaluated for morphological and agronomical characters at IAC during rainy and postrainy seasons. Considerable diversity was observed for all the characters studied. Diversity was more among states than within states. Variation among the seasons was also considerable. Days to flowering ranged from 42 to 129 days during postrainy and 33 to 180 days during the rainy season indicating their day length sensitivity. Plant height ranged from 65 to 330 cm during postrainy and 75 to 655 cm during rainy season. Panicle length ranged from 5 cm to 52 cm and panicle width from 1 to 51 cm. Erect and compact panicles are more frequent although all possible panicle shapes and compactness were found. In general, sorghums from India produce medium to large, lustrous grains in which the subcoat (testa) is absent. All the 5 basic and 10 intermediate sorghum races were found in India though durra or half-durra predominate. Racial diversity is maximal in the state of Andhra Pradesh followed by Maharashatra state. In the world collection a majority of the sources of resistance to shoot fly, stem borer, and striga are from India. Based on diversity for morphological and agronomical characters, India could be considered as the secondary center of diversity. Sorghum germplasm from India is useful for good quality large grai

An Insilco Approach to Restrain HIV Replication Through Clustering and Virtual Screening

Abstract Human Immunodeficiency Virus (HIV) type-1 non-nucleoside and nucleoside reverse transcriptase inhibitors (NNRTIs) are key drugs to inhibit replication of virus, we have used virtual screening and docking resulted in inhibit replication effectively at active binding site, 884 ligands were extracted and docking analysis resulted in 59 best molecules further by clustering analysis have paved the way for innovative drug design which is better than existing nevirapine ,top three molecules (ZINC04923148, ZINC05442451 and ZINC04923002) were reported as possible novel HIV-RT inhibitors

Interception of Peanut Stripe Virus in Soybean Seeds Imported from China

Investigations suggested that soyabean seeds, and the seeds of potential hosts of peanut stripe potyvirus imported to India from China, should be tested for the virus in quarantine

Survey for Peanut Stripe Virus in India

This virus, not previously reported from India, was identified on the basis of symptoms on groundnut and Chenopodium amaranticolor and serological tests in some of the entries in an initial evaluation trial obtained from NRGC or GAU, Junagadh. Efforts are being made to determine the original source of infested seed

Interception of Peanut Stripe Virus in Groundnut Germplasm Imported from China

Groundnut germplasm imported into India is subjected to the necessary)' quarantine processing negative seeds were grown separately in a screen for seedborne pathogens, in general and seedbome viral and bacterial pathogens, in particular. Peanut stripe virus (pStV), peanut mottle virus (pMV), peanut stunt virus (pSV), and the bacterial wilt pathogen Pseudomonas sofanacearum are seedborne in groundnut and are of quarantine importance to India...

BOBMEX: the Bay of Bengal monsoon experiment

The first observational experiment under the Indian Climate Research Programme, called the Bay of Bengal Monsoon Experiment (BOBMEX), was carried out during July-August 1999. BOBMEX was aimed at measurements of important variables of the atmosphere, ocean, and their interface to gain deeper insight into some of the processes that govern the variability of organized convection over the bay. Simultaneous time series observations were carried out in the northern and southern Bay of Bengal from ships and moored buoys. About 80 scientists from 15 different institutions in India collaborated during BOBMEX to make observations in most-hostile conditions of the raging monsoon. In this paper, the objectives and the design of BOBMEX are described and some initial results presented. During the BOBMEX field phase there were several active spells of convection over the bay, separated by weak spells. Observation with high-resolution radiosondes, launched for the first time over the northern bay, showed that the magnitudes of the convective available potential energy (CAPE) and the convective inhibition energy were comparable to those for the atmosphere over the west Pacific warm pool. CAPE decreased by 2-3 kJ kg-1 following convection, and recovered in a time period of 1-2 days. The surface wind speed was generally higher than 8 m s-1. The thermohaline structure as well as its time evolution during the BOBMEX field phase were found to be different in the northern bay than in the southern bay. Over both the regions, the SST decreased during rain events and increased in cloud-free conditions. Over the season as a whole, the upper-layer salinity decreased for the north bay and increased for the south bay. The variation in SST during 1999 was found to be of smaller amplitude than in 1998. Further analysis of the surface fluxes and currents is expected to give insight into the nature of coupling
