Personal Information Management of Ph.D. Scholars of Library and Information Science

Scholars are intensive users of information and study of their work has long been important to information science. In the course of their work, scholars generate large collections of information and managing this material must at least in part determine their effectiveness. This paper focuses on how scholars manage their information which is collected during Ph.D. work in print and digital format with using different methods as well as their own skills. E.g. they manage information by using web 2.0 tools, Information and communication technology, cataloguing skill, classification skill, etc., and how they deal with errors while they acquire, retrieve, store their information. The paper also indicates that Information Literacy programmes provided by libraries will help scholars in PIM

Molecular analysis reveals that lack of chasmothecia formation in Erysiphe necator in Maharashtra, India is due to presence of only MAT1-2 mating type idiomorph

The heterothallic, ubiquitous fungus Erysiphe necator causes powdery mildew disease of grapevines and in many countries it is reported to reproduce both asexually and sexually. Sexual reproduction results in the formation of chasmothecia (cleistothecia) on infected surfaces when the colonies of two opposite mating types meet on the infected plant parts and the temperatures are favorable for their development. Chasmothecia are reported from north India, but not from peninsular India, even though powdery mildew is reportedly present in these regions at least since the beginning of the last century. Through systematic survey of ten vineyards in Maharashtra and adjoining Karnataka in peninsular India, we confirmed the absence of chasmothecia under natural conditions. Analysis of temperature data from two locations in Maharashtra showed that the Tmax and Tmin were favourable for chasmothecia initiation (10 °C to 30 °C) and maturation (15 °C to 30 °C) for a sufficient period of time.Multiplex PCR of 120 E. necator field isolates collected from peninsular India showed presence of a single band of 232 bp corresponding to MAT1-2 mating type idiomorph or MAT- phenotype. None of the samples gave band of 408 bp corresponding to MAT1-1 mating type idiomorph. Further, two bands of 408 bp and 232 bp were detected in only one powdery mildew sample collected from Kashmir, in north India while the other nineteen samples gave a single band of 232 bp.  Thus, molecular analysis established that E. necator is not sexually reproducing in Maharashtra due to presence of only one mating type idiomorph. The study also brings out that MAT1-1 mating type idiomorph is not as common in nature as MAT1-2 and explains why in many other countries, too, chasmothecia were first observed as late as half to one century after start of grape cultivation.  &nbsp

Unusual landing of “Koth” Otolithoides biauritus by mini trawler at Versova, Mumbai.

A mini trawler landed an unusual catch of 103 numbers of “Koth” in the size range 770-1050mm each weighing between 2.5 to 5.0kg from a depth of 30 meters, at a distance of 25km off Mumbai, around the fishing grounds of Dahanu and Satpati

Dynamic Response of 2 Piles in Series and Parallel Arrangement

In the present study, dynamic analysis of laterally loaded vertical pile group is carried out by keeping in the mind the three dimensional nature of the soil-pile system. Piles and soil are modelled using three-dimensional finite element techniques treating them as linear elastic. The interface of soil and pile under the lateral load has been accounted for by incorporating interface elements in the modelling. The special type of transmitting boundary using Kelvin element is used to transfer the propagating waves from near field to the far field. Group of two piles in series and parallel configuration have been considered for present study. Individual piles are considered monolithic with pile cap. Parametric studies have been performed to examine the effects of pile spacing and soil modulus on the response of pile group

Green Building: Load Management Scheme for Flattening Household Electricity Usage or Demand

Flattening household electricity demand reduces generation costs, since costs are disproportionately affected by peak demands. Buildings today consume more energy than either of society?s other broad sectors of energy consumption industry and transportation. As a result, nearly half (47%) of energy use in residential buildings is lost in electricity transmission and distribution (T&D) from far-away power plants to distant homes. An important way to decrease both T&D losses and carbon emissions is through distributed generation (DG) from many small on-site renewable energy sources deployed at individual buildings and homes. Distributed generation (DG) uses many small onsite energy harvesting deployments at individual buildings to generate electricity. DG has the potential to make generation more efficient by reducing transmission and distribution losses, carbon emissions, and demand peaks. In this paper, we explore an alternative approach that combines market-based electricity pricing models with on-site renewables and modest energy storage (in the form of batteries) to incentivize DG called Green Building. The objectives of green charge is to develop an alternative approach that combines market-based electricity pricing models with on-site renewable and modest energy storage (in the form of batteries) to incentivize DG (Distributed Generation). We propose a system architecture and optimization algorithm, called Green Building, to efficiently manage the renewable energy and storage to reduce a building?s electric bill

Detonation modeling with the Particles on Demand method

A kinetic model based on the Particles on Demand method is introduced for gas phase detonation hydrodynamics in conjunction with the Lee--Tarver reaction model. The proposed model is realized on two- and three-dimensional lattices and is validated with a set of benchmarks. Quantitative validation is performed with the Chapman--Jouguet theory up to a detonation wave speed of Mach 20 in one dimension. Two-dimensional outward expanding circular detonation is tested for isotropy of the model as well as for the asymptotic detonation wave speed. Mach reflection angles are verified in setups consisting of interacting strong bow shocks emanating from detonation. Spherical detonation is computed to show viability of the proposed model for three dimensional simulations.Comment: Submitted to Physics of Fluids. 11 pages, 10 figure

Record of complete albinism in marine catfish, Osteogeneiosus militaris (Linnaeus, 1758), landed at Mumbai

Albinism is due to one of several gene mutations that affect the normal pigmentation. There are various degrees of albinism. True albino or amelanistic animals lack melanin and are white with unpigmented pink eyes

Information Technology Act 2000 in India - Authentication of E-Documents

The Information Technology Act 2000 has enacted in India on 9th June 2000. This Act has mentioned provision of authentication of electronic document. It is the need of hour at that time that such provision is needed in the Indian Law system, especially for electronic commerce and electronic governance. Electronic commerce”, which involve the use of alternatives to paper based methods of communication and storage information. To do electronic commerce there should be authentication of particular document. The working of internet is the documents are traveling in terms of bits from one destination to other destination, through various media like – Co-axial cable, fiber optic, satellite etc. While traveling this document there is probability of making changes in that document by any third party is high or some document may get changed due to noise/disturbance in communication media. This Act required to provide legal recognition carried out by means of electronic data interchange and other means of electronic communication
