Nuclear Waste and Native America: The MRS Siting Exercise

Drs. Gowda & Easterling provide cross-cultural perspectives on issues of risk perception, equity and policy as they affect nuclear waste storage on Native American sites

Extractive spectrophotometric determination of trace amounts of molybdenum using thiocyanate and ethylisobutrazine hydrochloride

An extractive spectrophotometric method for the determination of trace amounts of molybdenum in hydrochloric acid medium has been developed using potassium thiocyanate and ethylisobutrazine hydrochloride in the presence of ascorbic acid. The ternary complex that is extracted into chloroform has a molar absorptivity of 3.86 × 104 l mol–1 cm–1 at 460 nm. Beer's law is obeyed in the concentration range 0.05–5.6 p.p.m. The complex is stable for over 1 week. The effects of acid and reagent concentrations, time, temperature and foreign ions were investigated. The method has been applied to the determination of molybdenum in steel samples

PROBABILITY MODELS TO STUDY THE SPATIAL PATTERN, ABUNDANCE AND DIVERSITY OF TREE SPECIES

Ecological communities are composed of complex vegetation that differs from community to community and also within the community. The variability of tree species in the community in relation to their environments can be studied by using different statistical tools. The present study was conducted to describe and also to quantify the spatial pattern, abundance and diversity of tree species in the Western Ghats of Karnataka. The spatial pattern of tree species was studied by using Poisson and Negative binomial distributions. Results indicate that most of the selected tree species followed Negative binomial distribution having clumped pattern. The Species abundance distribution was studied by using log series and lognormal distributions in six different forest types (Evergreen, semievergreen, moist deciduous, dry deciduous, scrub and shola forest types). All six different forest types followed lognormal distribution where as evergreen and shola forest types followed log series distribution also. Diversity of the tree species in different forest types was quantified by different diversity indices; it was found that evergreen forest is most diverse

4-Chloro-N-(3-methyl­benzo­yl)benzene­sulfonamide monohydrate

In the title compound, C14H12ClNO3S·H2O, the dihedral angle between the sulfonyl and benzoyl benzene rings is 84.4 (2)°. In the crystal, every water mol­ecule forms four hydrogen bonds with three different mol­ecules of 4-chloro-N-(3-methyl­benzo­yl)benzene­sulfonamide. One of the water H atoms forms a bifurcated hydrogen bond with both the sulfonyl and the carbonyl O atoms of the same mol­ecule. Mol­ecules are linked into layers in the ab plane through N—H⋯O and O—H⋯O hydrogen bonds

Towards Economic empowerment: study of rural women in dairy cooperatives of Heggada Devana Kote taluk in Mysore district

Women play a vital role in the dairy sector of India. Dairy cooperatives provide sustainable livelihood to millions of household in rural India. Several initiatives for empowerment of women are undertaken by Government of India, State Governments and Non-Government Organizations. As a feature of patriarchal society, women's contributions are rendered 'invisible' and unacknowledged in general; it's no different in dairying, livestock management and agriculture. Even in dairy development programmes, the central focus is predominantly on milk, milk products and livestock rather than on women. The scenario is fast changing with the increasing recognition of the dynamic role played by women and the inherent advantages of women empowerment for 'smart' economics and superior society. Studies from a gender perspective on rural dairy women to analyze their progress, problems and prospects at the grassroots are considerably rare. This paper aims to contribute towards bridging research gaps by examining the growth of economic status of women in dairy cooperative societies of rural India. This empirical study involves 160 women from 16 women dairy cooperative societies of Karnataka Milk Federation (KMF) in Heggada Devana Kote Taluk. Comprehensive pre-tested questionnaire was used for the purpose of primary data collection along with interview guide and field observations. The study examines the changes in income, access to cash and credit, confidence in financial transactions and their aspiration for economic autonomy towards drawing inferences and suggestions for engendering and strengthening endeavors for economic empowerment of women in dairy cooperatives

Embryological studies inMecardonia procumbens (Miller) small

Sporogeneses, development of gametophytes, endosperm and embryo ofMecardonia procumbens (Miller) Small have been described. The wall of the microsporangium consists of an epidermis, an endothecium, a middle layer and a glandular tapetum. The development of the anther conforms to the dicotyledonous type. The tapetal cells become binucleate and the endothecial cells acquire fibrous thickenings in later stages. Quadripartition of the microspore mother cells is simultaneous. Pollen grains are shed at two-celled stage and are tricolpate. Development of the female gametophyte is of Polygonum type. Middle part of the gametophyte is surrounded by an endothelium. Endosperm is ofab initio cellular type. Chalazal and micropylar haustoria are organised. Both the micropylar and chalazal haustoria are four-celled and this is the first report in the tribe Gratioleae. Embryo development is of Onagrad type. The cell ‘d’ functions as the hypophyseal cell
