Growth of sugar cane varieties under salinity

ABSTRACT Large salty areas in the Brazilian semi-arid region have limited farming in Northeastern Brazil. One example is the sugar cane cultivation, which reinforces the need of selecting varieties that are more tolerant to salinity. The objective of this study was to evaluate the effect of salinity on growth of ten varieties of sugar cane. The experiment was conducted in a greenhouse, set in the experimental field of Embrapa Semi��rido, in Petrolina, Pernambuco State. The experimental design was randomized blocks arranged in a 6 X 10 factorial arrangement, comprised of six levels of salinity (0, 1.0, 2.0, 4.0, 6.0 and 8.0 dS m-1) and ten sugar cane varieties (VAT 90212; RB 72454; RB 867515; Q 124; RB 961003; RB 957508; SP791011; RB 835089; RB 92579 and SP 943206). Salt levels of irrigation water were obtained by adding NaCl, CaCl2.2H2O and MgSO4.7H2O to achieve an equivalent ratio among Na:Ca:Mg of 7:2:1. Sixty days later, plant height, stem diameter (base), number of leaves, stalks and sprouts, leaf area and fresh and dry mass of the aerial part and roots were all measured. The varieties of sugar cane showed similar responses for growth reduction as soil salinity increases, being considered moderately sensitive to salinity.

Neutron activation analysis of wheat samples

The deficiency of essential micronutrients and excess of toxic metals in cereals, an important food items for human nutrition, can cause public health risk. Therefore, before their consumption and adoption of soil supplementation, concentrations of essential micronutrients and metals in cereals should be monitored. This study collected soil and two varieties of wheat samples���Triticum aestivum L. (Jord��o/bread wheat), and Triticum durum L. (Marialva/durum wheat) from Elvas area, Portugal and analyzed concentrations of As, Cr, Co, Fe, K, Na, Rb and Zn using Instrumental Neutron Activation Analysis (INAA) to focus on the risk of adverse public health issues. The low variability and moderate concentrations of metals in soils indicated a lower significant effect of environmental input on metal concentrations in agricultural soils. The Cr and Fe concentrations in soils that ranged from 93���117 and 26,400���31,300 mg/kg, respectively, were relatively high, but Zn concentration was very low (below detection limit <22 mg/kg) indicating that soils should be supplemented with Zn during cultivation. The concentrations of metals in roots and straw of both varieties of wheat decreased in the order of K>Fe>Na>Zn>Cr>Rb>As>Co. Concentrations of As, Co and Cr in root, straw and spike of both varieties were higher than the permissible limits with exception of a few samples. The concentrations of Zn in root, straw and spike were relatively low (4���30 mg/kg) indicating the deficiency of an essential micronutrient Zn in wheat cultivated in Portugal. The elemental transfer from soil to plant decreases with increasing growth of the plant. The concentrations of various metals in different parts of wheat followed the order: Root>Straw>Spike. A few root, straw and spike samples showed enrichment of metals, but the majority of the samples showed no enrichment. Potassium is enriched in all samples of root, straw and spike for both varieties of wheat. Relatively to the seed used for cultivation, Jord��o presented higher transfer coefficients than Marialva, in particular for Co, Fe, and Na. The Jord��o and Marialva cultivars accumulated not statistically significant different concentrations of different metals. The advantages of using INAA are the multielementality, low detection limits and use of solid samples (no need of digestion).

Probing the scalar-pseudoscalar mixing in the 125 GeV Higgs particle with current data

LHC has found hints for a Higgs particle of 125 GeV. We investigate the possibility that such a particle is a mixture of scalar and pseudoscalar states. For definiteness, we concentrate on a two-Higgs doublet model with explicit CP violation and soft Z(2) violation. Including all Higgs production mechanisms, we determine the current constraints obtained by comparing h -> yy with h -> VV*, and comment on the information which can be gained by measurements of h -> b (b) over bar. We find bounds vertical bar s(2)vertical bar less than or similar to 0.83 at one sigma, where vertical bar s(2)vertical bar = 0 (vertical bar s(2)vertical bar = 1) corresponds to a pure scalar (pure pseudoscalar) state.

Utilidade dos estudos de condu����o nervosa e respostas-F do nervo peronial na radiculopatia de L5 e a sua correla����o com o grau de gravidade avaliada eletromiograficamente

As radiculopatias lombares referem-se a um processo patol��gico envolvendo as ra��zes nervosas espinais, causando sintomas radiculares ao n��vel dos membros inferiores. As respostas-F s��o ondas tardias que adv��m de descargas recorrentes de neur��nios motores despolarizados antidromicamente, que podem ser ��teis na avalia����o de les��es radiculares. Com o objetivo de avaliar a utilidade dos estudos de condu����o nervosa e respostas- F do nervo peronial no diagn��stico de radiculopatia de L5 e a sua correla����o com o seu grau de gravidade, foram estudados 47 sujeitos que padeciam de radiculopatia de L5 e foram comparados com um grupo de controlo, constitu��do por 28 sujeitos saud��veis. Foram estudadas as amplitudes do PAMC do nervo peronial profundo, do PANS do peronial superficial, bem como as lat��ncias m��nima, m��dia e m��xima, cronodispers��o e persist��ncia das Respostas-F. Foi realizada ainda uma avalia����o eletromiogr��fica, com o intuito de classificar o acometimento da raiz em termos de gravidade. Registaram-se diferen��as significativas entre os dois grupos na amplitude do PAMC do peronial profundo (p<0,0001), na F-m��nima, F-m��dia, F-m��xima e cronodispers��o (p<0,0001), e ainda na persist��ncia (p 0,014). Todos estes par��metros tamb��m se correlacionaram significativamente com o grau de gravidade da radiculopatia, sendo as lat��ncias das ondas-F e a cronodispers��o progressivamente maiores nos sujeitos com um grau de afe����o mais grave, e a persist��ncia e a amplitude dos estudos de condu����o motora mais baixas. O fator que se evidenciou mais sens��vel no diagn��stico desta patologia foi a lat��ncia-m��xima das ondas-F, 31,25%, e o menos sens��vel a persist��ncia, apenas alterada em 9,34% dos indiv��duos. Tendo em considera����o todos os par��metros avaliados nas respostas-F atingiu-se uma sensibilidade global desta t��cnica de 42,19%. Com esta investiga����o conclu��mos que os estudos de condu����o nervosa e as respostas-F poder��o ser ��teis como complemento na avalia����o das radiculopatias lombares, apresentando uma sensibilidade consider��vel para esta patologia. N��o se deve limitar o estudo desta t��cnica �� avalia����o das lat��ncias m��nima das ondas-F, mas incluir sempre todos os outros par��metros, aumentando assim a sua sensibilidade. Estas t��cnicas dever��o ser inclu��das no estudo das radiculopatias de L5.

About hazing In higher education

Not a year goes by that we don't hear of another hazing scandal in a higher education institution. Many researchers took interest in this issue in order to understand its causes and consequences. They provided definitions and lead to prevent it. We found hazing in many social groups around the world, with different names, and under specific forms. This paper aims to better understand hazing and its actors, with a specific focus on hazing in higher education. We presented three definitions to offer several perspectives on hazing, and facilitate its apprehension. Our method was to analyze the relevant scientific literature with the intention of reflecting on its roots and representation among individuals. Results are an exposition of motivations from hazing's actors, recommendations about how to define it and how to prevent derivations. Our main conclusions assume hazing is usually depicted as a deviant behavior, but it would appear to be a norm. Also, its core purpose would be the progression from newcomer to a group member. A lack of structure or meaning could lead to its misuse and facilitate outrageous events. In higher education, hazing seems to be used as a tool to integrate freshmen in their new institutional world. Scandals including violence, sexual and alcohol abuse could be a symptom of something deeper from hazing's environment.

Literature, translation and national identity: Christina Rossetti and Rosal��a de Castro in the work of Pl��cido Castro

Pl��cido Castro���s work has aroused our interest, because it evolves around the question of Galician personality and identity. While working as a journalist and a translator or while writing essays on different literary issues, Pl��cido Castro has never forgotten his roots or his nation. One could even say that his whole life turns around Galicia. Our purpose is to make a critical analysis of his work, especially as a translator, and try to show how he used translation in order to develop national conscience and identity and to see how far his ideology interfered in the interpretation and translation of Rossetti���s poetry, in which he found a great similarity with Rosal��a de Castro���s work.

Trends in public health policies addressing violence against women

OBJECTIVE To analyze the content of policies and action plans within the public healthcare system that addresses the issue of violence against women.METHODS A descriptive and comparative study was conducted on the health policies and plans in Catalonia and Costa Rica from 2005 to 2011. It uses a qualitative methodology with documentary analysis. It is classified by topics that describe and interpret the contents. We considered dimensions, such as principles, strategies, concepts concerning violence against women, health trends, and evaluations.RESULTS Thirteen public policy documents were analyzed. In both countries&#8217; contexts, we have provided an overview of violence against women as a problem whose roots are in gender inequality. The strategies of gender policies that address violence against women are cultural exchange and institutional action within the public healthcare system. The actions of the healthcare sector are expanded into specific plans. The priorities and specificity of actions in healthcare plans were the distinguishing features between the two countries.CONCLUSIONS The common features of the healthcare plans in both the counties include violence against women, use of protocols, detection tasks, care and recovery for women, and professional self-care. Catalonia does not consider healthcare actions with aggressors. Costa Rica has a lower specificity in conceptualization and protocol patterns, as well as a lack of updates concerning health standards in Catalonia.
