Development of a nuclear technique for monitoring water levels in pressurized vehicles

A new technique for monitoring water levels in pressurized stainless steel cylinders was developed. It is based on differences in attenuation coefficients of water and air for Cs137 (662 keV) gamma rays. Experimentally observed gamma ray counting rates with and without water in model reservoir cylinder were compared with corresponding calculated values for two different gamma ray detection theshold energies. Calculated values include the effects of multiple scattering and attendant gamma ray energy reductions. The agreement between the measured and calculated values is reasonably good. Computer programs for calculating angular and spectral distributions of scattered radition in various media are included

Population dynamics of mycorrhizal fungi in rhizosphere of pigeon pea [Cajanus cajan (L.) Millsp.]

Soil samples collected from the rhizosphere of Pigeon pea [Cajanus cajan (L.) Millsp.] to evaluate the population dynamics of vesicular arbuscular mycorrhizae (VAM). Root colonization by native VAM fungi was recorded minimum in early stages of plant growth which significantly increased with the age of plants and became highest at maturity. Maximum VAM colonization in different blocks of the district ranged between 71-86% during both the years. Spore population was recorded maximum in soil samples collected at early stage of plant growth which significantly decreased of VAM fungi belonging 4 genera (Glomus sclerocystis, Acaulospora endogen) were identified. Among these Glomus mosseae and Sclerocystis rubiformis were found most dominating and widely distributed in all the blocks followed by Acaulospora longula  and Sclerocystis clavispora  which were distributed only in 12 blocks of the district. Acaulospora spinosa and Glomus diaphanum were recorded only from two blocks and their prevalence were least. Colonization per cent have negative correlation with spore density at different crop growth stages

Visual selective attention is equally functional for individuals with low and high working memory capacity: Evidence from accuracy and eye movements

Selective attention and working memory capacity (WMC) are related constructs, but debate about the manner in which they are related remains active. One elegant explanation of variance in WMC is that the efficiency of filtering irrelevant information is the crucial determining factor, rather than differences in capacity per se. We examined this hypothesis by relating WMC (as measured by complex span tasks) to accuracy and eye movements during visual change detection tasks with different degrees of attentional filtering and allocation requirements. Our results did not indicate strong filtering differences between high- and low-WMC groups, and where differences were observed, they were counter to those predicted by the strongest attentional filtering hypothesis. Bayes factors indicated evidence favoring positive or null relationships between WMC and correct responses to unemphasized information, as well as between WMC and the time spent looking at unemphasized information. These findings are consistent with the hypothesis that individual differences in storage capacity, not only filtering efficiency, underlie individual differences in working memory

Turning the co-production corner: methodological reflections from an action research project to promote LGBT inclusion in care homes for older people

Background: Older lesbian, gay, bisexual and trans (LGBT) residents are often invisible in long-term care settings. This article presents findings from a community-based action research project, which attempted to address this invisibility through co-produced research with LGBT community members. Particular Question: What conditions enable co-produced research to emerge in long-term residential care settings for older people? Aims of Project: To analyse outcomes and challenges of action-oriented, co-produced research in the given context. In particular, we explore how co-production as a collaborative approach to action-orientated research can emerge during the research/fieldwork process; and reflect critically on the ethics and effectiveness of this approach in advancing inclusion in context. Methods: The project was implemented across six residential care homes in England. Reflections are based on qualitative evaluation data gathered pre- and postproject, which includes 37 interviews with care home staff, managers and community advisors (two of whom are co-authors). Results and Conclusions: We discuss how the co-production turn emerged during research and evaluate how the politics of this approach helped advance inclusion—itself crucial to well-being. We argue for the value of co-produced research in instigating organizational change in older people’s care environments and of non-didactic storytelling in LGBT awareness raising amongst staff

Mycorrhizal population of Indian mustard at different location of district Baharaich, Uttar Pradesh

Soil samples were collected from the rhizosphere of Indian mustard [Brassica juncea (L.)Czern & Coss.] to evaluate the population dynamics of VA mycorrhizae. Root colonization in this crop varied from 27.53% to 43.53% at different places of district Baharaich of Uttar Pradesh, while spore population ranged between 100 to 380 per 100 g soil in different samples. Maximum colonization and spore population were observed in block Shivpur followed by Mihinpurwa and Huzurpur but these were at par. Sixteen species of VAM fungi belonging to 4 different genera were identified. Among these Glomus mosseae and Glomus fasciculatum were found most dominating and distributed in 10 blocks followed by Acaulospora longula and Sclerocystis rubiformis which were distributed only in 7 blocks of the district. VAM fungi  Acaulospora elegans and Acaulospora sporocarpa were found only in block Nanpara. Colonization per cent has significant and positive correlation with spore density. Physico-chemical properties of the soil specially pH, organic carbon, available nitrogen, available phosphorus and available potassium influence the population dynamics and colonization of VA mycorrhiza in mustard crops

Cohomology of bundles on homological Hopf manifold

We discuss the properties of complex manifolds having rational homology of $S^1 \times S^{2n-1}$ including those constructed by Hopf, Kodaira and Brieskorn-van de Ven. We extend certain previously known vanishing properties of cohomology of bundles on such manifolds.As an application we consider degeneration of Hodge-deRham spectral sequence in this non Kahler setting.Comment: To appear in Proceedings of 2007 conference on Several complex variables and Complex Geometry.

Linear Multivariable Regression Models for Prediction of Eddy Dissipation Rate from Available Meteorological Data

Linear multivariable regression models for predicting day and night Eddy Dissipation Rate (EDR) from available meteorological data sources are defined and validated. Model definition is based on a combination of 1997-2000 Dallas/Fort Worth (DFW) data sources, EDR from Aircraft Vortex Spacing System (AVOSS) deployment data, and regression variables primarily from corresponding Automated Surface Observation System (ASOS) data. Model validation is accomplished through EDR predictions on a similar combination of 1994-1995 Memphis (MEM) AVOSS and ASOS data. Model forms include an intercept plus a single term of fixed optimal power for each of these regression variables; 30-minute forward averaged mean and variance of near-surface wind speed and temperature, variance of wind direction, and a discrete cloud cover metric. Distinct day and night models, regressing on EDR and the natural log of EDR respectively, yield best performance and avoid model discontinuity over day/night data boundaries

Goal-neglect links Stroop interference with working memory capacity

Relationships between Stroop interference and working memory capacity may reflect individual differences in resolving conflict, susceptibility to goal neglect, or both of these factors. We compared relationships between working memory capacity and three Stroop tasks: a classic, printed color-word Stroop task, a cross-modal Stroop, and a new version of cross-modal Stroop with a concurrent auditory monitoring component. Each of these tasks showed evidence of interference between the semantic meaning of the color word and the to-be-named color, suggesting these tasks each require resolution of interference. However, only Stroop interference in the print-based task with high proportions of congruent trials correlated significantly with working memory capacity. This evidence suggests that the relationships observed between Stroop interference and working memory capacity are primarily driven by individual differences in the propensity to actively maintain a goal.

Guar -A nutrimental potent ethnomedicinal cultivated forage

ABSTRACT Bahraich U.P., India is blessed with diversified flora of more than 1200 plant species with Tharu tribals inhabiting inside as well as around the forests. The tribals have strong belief in magico therapeutic properties of plants for treatment of their ailments. The vegetation of the areas is mainly characterized by member of herbaceous plants growing on a variety of habitats along with scattered occurrence of many indigenous and exotic species of trees and shrubs in open areas or cultivated in gardens and along the road sides. The North Western Tarai belt in which Bahraich is situated is next to Himalaya which represents one of the thirty four hot spots of the World mega biodiversity. In spite of all, the wealth of traditional knowledge is being lost, as the traditional culture is gradually disappearing. Cyamopsis tetragonaloba (L.) Taub. belongs to Leguminosae, commonly known as cluster bean, guar, gvar, gwar or guwar bean, is an annual legume. This plant is cultivated for forage, to improve soil fertility, in mixed cropping as well as in crop rotation.
