    Breast Cancer Awareness among Females in a Developing world- A Study from Kashmir

    Background: Breast cancer is a major health issue and in developing regions, where the early cancer detection facilities are unavailable awareness about this disease can lead to early detection and thereby potentially decrease the morbidity and mortality.Methods: A self designed questionnaire was used to study the level of awareness regarding breast cancer among 864 Kashmiri females. The questionnaire had 18 questions and on the basis on score attained, the subjects were classified as having poor, average or good breast cancer awareness.Results: Out of 864 participants, 703(81.37%) had poor breast cancer awareness and 103(11.92%) had average awareness. Only 58(6.71%) had good awareness about breast cancer.Conclusion: The level of awareness regarding breast cancer in Kashmiri females is very low and there is a need to spread awareness about this disease among the general population

    SHORT-TERM EFFECTS OF CROP HUSBANDRY ON THE WEED COMMUNITY OF A CEREAL-LEGUME ROTATION, “TILMAN-ORG session”

    Several agricultural practices can be used to control weed population thus avoiding the use of herbicides. Tillage, fertilization and growth of a green manure are found among them. In the context of a mid-term experiment set up in an organic field in Gallecs (Barcelona), we analysed the effect of chisel vs mouldboard ploughing, application of fertilizer and growth of a green manure on the density of weeds and on composition of the weed community. We evaluated weed density and community composition in April 2012 (spelt crop), February 2013 (green manure cover) and May 2013 (chickpea crop) and also analysed the sources of variation of density for the most abundant species in all periods. Our results show that, under the cereal crop, mouldboard plough had a negative effect on weed densities and also affected weed community composition. While green manure was standing on the field, its presence also had a negative effect on weed density. We found differences in composition between sown and unsown plots. After removal of green manure, though, these effects disappeared. For total weed density in the chickpea crop, we could not find differences due to any of the treatments applied. However, single species analyses showed that Setaria viridis and Polygonum convolvulus responded positively to tillage and fertilization and that P. convolvulus and Convolvulus arvensis were negatively affected by previous presence of green manure. Weed community composition were found to be unaffected by any of our treatments

    Circulación marina en la plataforma continental del Ebro determinada a partir de la distribución de masas de agua y los microcontaminantes orgánicos en el sedimento

    XI Congreso Español de Sedimentología, celebrado del 15 al 18 de septiembre de 1986 en Barcelona.-- 7 pages, 6 figures[ES] El análisis hidrográfico de las masas de agua en la plataforma continental del Ebro y las concentraciones de diversos microcontaminantes orgánicos en los sedimentos en las proximidades del delta, permiten aportar conclusiones sobre el régimen de circulación marina. Las aguas del río son frenadas por la corriente procedente del NE, ocasionando que parte del material en suspensión sedimente en el centro de un giro anticiclónico que se forma cerca de la desembocadura. El resto del material particulado es arrastrado hacia el S y desplazado progresivamente hacia la costa[EN] The continental margin of Ebro River delta lays in the region of the general southwestwards circulation of the Northwestern Mediterranean. South of paralle141° N the continental shelf widens suddenly and causes a deflection of 90" in the direction of the isobaths. The continental slope becomes then a barrier for the progression of the main current. The important discharge of Ebro river waters also influences the circulation on the continental shelfPeer reviewe
