Botanical and molecular evidences of landraces from the germplasm exclusively collected from Baluchistan, a centre of diversity for Lens culinaris
Botanical descriptors, total seed proteins, isozymes and RAPD markers were applied to identify landraces from indigenous lentil germplasm exclusively collected from the province of Baluchistan, Pakistan. The Germplasm revealed the prevalence of landraces, especially on the basis of isozymesand RAPD markers. Dversity explored through various techniques revealed validity irrespective of the sample size from a particular district, RAPD being the best choice for investigating both inter and intraaccession variation that is needed to extend to more germplasm study along with botanical descriptors
The spherical symmetry Black hole collapse in expanding universe
The spherical symmetry Black holes are considered in expanding background.
The singularity line and the marginally trapped tube surface behavior are
discussed. In particular, we address the conditions whether dynamical horizon
forms for these cosmological black holes. We also discuss about the
cosmological constant effect on these black hole and the redshift of the light
which comes from the marginally trapped tube surface.Comment: 7 pages, 3 figures. Accepted for publication in International Journal

Radiative Heat Transfer Flow of Micropolar Fluid with Variable Heat Flux in a Porous Medium
A two-dimensional steady convective flow of a micropolar fluid past a vertical porous flat plate in the presence of radiation with variable heat flux has been analyzed numerically. Using Darcy-Forchheimer model the corresponding momentum, microrotation and energy equations have been solved numerically. The local similarity solutions for the flow, microrotation and heat transfer characteristics are illustrated graphically for various material parameters. The effects of the pertinent parameters on the local skin friction coefficient, plate couple stress and the heat transfer are also calculated. It was shown that large Darcy parameter leads to decrease the velocity while it increases the angular velocity as well as temperature of the micropolar fluids. The rate of heat transfer in weakly concentrated micropolar fluids is higher than strongly concentrated micropolar fluids
Photoelectron angular distribution of the excited 2p^2 3p ^2S state of atomic nitrogen
Relevant data is available at: http://www.astronomy.ohio-state.edu/~nahar/nahar_radiativeatomicdata/index.htmlCalculations of the photoelectron angular distribution asymmetry parameter ß for the excited 2p^2 3p ^2S state of atomic nitrogen have been performed using Hartree-Fock discrete and continuum wave functions with relaxation. The results show reasonably good agreement with a recent measurement of ß at a single energy.The work was supported by the U.S. Army Research Office and the National Science Foundation
Efectos inducidos por el hábitat sobre mutaciones y perfil de ácidos grasos en carpas mrigala que habitan en el fondo del río Chenab
Fish from the river Chenab were analyzed for DNA damage by the Comet and Micronucleus assays. The fatty acid profile was determined by gas chromatography using a Flame Ionization Detector. Atomic absorption spectrophotometry showed significant (p < 0.05) levels of contamination due to Cd, Hg, Cu, Mn, Zn, Pb, Cr, Sn and phenols in the fish habitat. The Comet assay revealed significant (p < 0.05) DNA damage in Cirrhinus mrigala of 37.29±2.51%, 34.96±2.53% and 38.80±2.42% in the comet tail, in the tail moment of 23.48±3.90, 19.78±4.26 and 14.30±1.82, in the olive moment of 16.22±2.04, 13.83±1.96 10.99±0.90, respectively, from three experimental sites. The micronucleus assay showed a high frequency of single micronucleus induction of 44.80±3.73, double induction of 06.20±0.97 and nuclear abnormalities of 09.60±1.72, as calculated in a thousand cells. C8:0, C12:0, C20:0, C16:1(n-7), C16:1(n-9), C20:1(n-9), C18:2(n-6), C18:4(n-3), C20:5(n-3), C22:4(n-6) fatty acids were found missing in the fish with a higher intensity of DNA damage but were found in optimal amounts both in farmed and wild fish from non polluted habitats. A highly significant (p < 0.01) correlation was also found in saturated, unsaturated fatty acids and DNA damage and habitat. The present study revealed that the habitat of even lower intensity pollutions not only induce DNA damage but also confiscate essential fatty acids of the omega series and reduce the amount of unsaturated fatty acids for which fish is preferred over other animals.Los daños en el ADN de los peces del río Chenab se analizaron mediante la técnica del “ensayo del cometa” y el ensayo de micronúcleos. El perfil de ácidos grasos se determinó mediante cromatografía de gases con detector de ionización de llama. La espectrofotometría de absorción atómica mostró diferencias significativas (p < 0.05) de los niveles de contaminación por Cd, Hg, Cu, Mn, Zn, Pb, Cr, Sn y fenoles en el hábitat de los peces. El ensayo del cometa mostró daños significativos (p < 0,05) en el ADN de las carpas mrigala de tres sitios experimentales: 37,29±2,51%, 34,96±2,53 y 38,80±2,42% del ADN en la cola del cometa, momento de la cola con 23,48±3,90, 19,78±4,26 y 14,30±1,82% y cola media con 16,22±2,04, 13,83±1,96 10,99±0,90. Los ensayos de micronúcleos mostraron una alta frecuencia de inducción de micronúcleos como única 44,80±3,73, 06,20±0,97 y doble anomalías nucleares 09,60±1,72 calculados en miles de células. C8:0, C12:0, C20:0, C16:1(n-7), C16:1 (n-9), C20:1(n-9), C18:2(n-6), C18:4(n-3), C20:5(n-3) y C22:4(n-6) se mostraron como ácidos grasos que faltan en el pescado que tiene una mayor intensidad de daño en el ADN, aunque se encuentran en cantidades óptimas, tanto en los peces de piscifactoría como en los salvajes donde no hay hábitats contaminados. Se encontró una correlación altamente significativa (p < 0,01) también en ácidos saturados, ácidos grasos insaturados, daño del ADN y hábitat. El presente estudio reveló que la intensidad de la contaminación del hábitat aún en la más baja no sólo induce daño en el ADN, sino también en la composición de los ácidos grasos de la serie omega y de los ácidos grasos insaturados, para los que se prefiere ingerir pescado a otros animales

Socio-economic inequalities in health among older adults in two rural sub-districts in India and Bangladesh: a comparative cross-sectional study
Health inequalities have been observed among older people in many developing countries, particularly among those with least social protection and low socio-economic (SES) status. This study attempted to examine effects of SES on the health of older adults, and related gender differences, in two rural sub-districts - Matlab, Bangladesh and Vadu, India. The study utilised the WHO SAGE INDEPTH Wave 1, 2007 Matlab, Bangladesh and Vadu, Pune District, India datasets. Both gender and SES indicators were strongly associated with all health indicators of older adults in the Bangladesh site, whereas in India, education and asset quintiles were not consistently associated with self-rated health, quality of life and functional ability score but gender was consistently associated with all health indicators except the quality of life score. The SES-health gradient was noticeably higher amongst older adults in Matlab, Bangladesh than in Vadu, India. Education was also found to be an important predictor of health outcome in both sites
The international symposia on career development and public policy: retrospect and prospect
Between 1999 and 2011, seven international symposia on career development and public policy were held at various venues across the world, and an International Centre was established to support and maintain continuity between these events. These developments were closely intertwined with a number of other significant international developments. The origins of the symposia are described; their core design features are defined; their evolution is outlined and reviewed; and their impact is assessed. This article concludes with a discussion of the prospects for future symposia and for the International Centre
