Molybdenum is one of the essential micronutrients for soybeans, acting directly on nitrogen metabolism as enzyme cofactor of nitrogenase. Usually, this nutrient is supplied to the plants through seed treatment or foliar application. The aim of this study was to evaluate the molybdenum effects by foliar in the physiological potential of soybean seeds and verify its interference in the enzyme activities involved in nitrogen metabolism. Soybean seeds of BMX Turbo cultivar were used, produced in Erechim, RS, harvest 2013, from plants treated with the following Mo concentrations: 0; 25; 50 and 75 g ha-1, supplied through two commercial products (Biomol and Molybdate) and stored during 0 and 6 months in uncontrolled conditions. The first experiment was conducted in Seedtes Seed Analysis Laboratory in Pato Branco, PR. The used design was completely randomized in a factorial analysis 4 x 2 x 2 with four replications each. The physiological potential of the seeds was evaluated by the germination test, seedling growth, accelerated aging and emergence on the soil. The second experiment was conducted in a greenhouse, where the seeds derived from treatments with different concentrations of Mo: 0; 25; 50 and 75 g ha-1 supplied through two commercial products (Biomol and Molybdate) were grown in vases. The used design was completely randomized in a factorial analysis 4 x 2 with four replications. Evaluations were performed when the plants reached the R1 phenological stage concerning the nodulation, dry matter of root and shoot of the plants and the determination of the activity of the enzymes glutamine synthetase and glutamate synthetase and the content of total soluble proteins. The data were submitted to variance analysis and when significant they were assessed by Tukey’s test for comparison of products and seed storage and with regression study to the concentrations at 5% probability. Analyses were performed using SISVAR statistical software. The soybean seed storage under uncontrolled conditions affected the seed vigour produced with Mo, regardless of the commercial product used during production. The application of Mo through foliar positively influences the production of soya beans which presented increasing responses in the germination and vigour with the application of Mo above 25 g ha-1 . The enrichment of Mo through foliar did not affect the nodulation of plants of the next generation, however, the use of Mo above 25 g ha-1 provided an increase in the activity of enzymes involved in nitrogen metabolism as well as on the total protein content.

Introdução: no Brasil, a violência contra a mulher foi reconhecida somente com a Convenção Belém do Pará, em 1995. A partir daí, inúmeras medidas para prevenção e combate foram instituídas, entre elas a criação das Delegacias Especializadas de Atendimento às Mulheres (DEAM) e a Lei Maria da Penha. No entanto, muitas mulheres ainda são vitimadas, na maioria das vezes dentro do próprio lar. Objetivos: delinear o perfil das mulheres vítimas de violência; identificar as formas de violência registradas na DEAM da cidade do Rio Grande/RS; identificar os motivos que levam à prática da violência e descrever os atos violentos perpetrados, por parceiro íntimo, às mulheres que registraram ocorrência na DEAM. Metodologia: estudo documental, quanti e qualitativo, de natureza exploratória, descritiva e delineamento transversal. Fizeram parte do estudo todas as ocorrências cujas vítimas eram mulheres com 18 anos ou mais. O espaço temporal adotado estendeu-se de agosto de 2009, quando foi implantada a delegacia, a dezembro de 2011. Os dados foram coletados entre outubro de 2011 e março de 2012. Para a coleta, foi elaborado e aprovado, após testagem, um instrumento contendo informações acerca do agressor, da vítima, bem como do tipo de violência praticada. Os dados foram digitados em planilhas do tipo Excel. A análise quantitativa foi efetuada por meio de estatística descritiva e do software estatístico SPSS versão 17.0. Para o estudo qualitativo utilizou-se a análise de conteúdo. Esse projeto foi aprovado pelo Comitê de Ética em Pesquisa na Área da Saúde, da Universidade Federal do Rio Grande sob Parecer no 137/2011. Resultados: estão descritos em dois artigos. Analisaram-se 902 ocorrências policiais evidenciando-se que a maioria das vitimas eram mulheres brancas, jovens, com baixa escolaridade. Ainda foi possível identificar que o Centro da cidade ocupou a segunda posição como local de moradia das vítimas, desmitificando a idéia de que a violência predomina na periferia. A violência física prevaleceu nos registros notificados, seguida do descumprimento de ordem judicial. Além disso, encontrou-se a reincidência de denúncias, o que pode estar atrelado à morosidade judicial. Observou-se também, que existem diversos motivos desencadeadores da violência, no entanto todos eles apresentam como pano de fundo as questões associadas ao gênero. A simultaneidade da violência bem como a extensão aos filhos, família e sociedade retratam a gravidade do fenômeno e a necessidade de se rever a resolutividade das medidas protetivas e das penas atribuídas aos agressores. Conclusões: este estudo expôs, parcialmente, a situação da violência contra a mulher no município, pois se sabe que existem muitos casos velados que não chegam a ser notificados. Entretanto, evidenciou-se o predomínio da violência física cometida por parceiro íntimo repercutindo em graves consequências à vida das vítimas. Assim, julga-se ímpar a implementação de uma rede efetiva de apoio a essas mulheres bem como a atuação de equipe multidisciplinar capacitada, coesa e sensível ao problema, incluindo os profissionais da saúde, que precisam, ainda, estar ciente da obrigatoriedade da notificação compulsória, fundamental para a formulação de novas políticas públicas de combate e prevenção a esse fenômeno.

O tema alimentação é uma preocupação nos dias atuais. O aparecimento de doenças associadas aos excessos alimentares, diferentes culturas e informação transmitida, são problemas constantes e preocupantes na sociedade. As pessoas têm de ser educadas desde pequenas para esta situação, valorizando toda a informação que recolhem por parte do meio envolvente e colocando em prática o que aprenderam. Este trabalho baseou-se na avaliação de alguns indivíduos sobre o conhecimento e práticas que têm sobre o tema alimentação saudável. Escolheu-se um grupo de indivíduos que frequentavam do 5º ao 9º ano de escolaridade, do concelho de Viseu. O objectivo pretendido consistia em avaliar o conhecimento adquirido no convívio com a família e amigos, na escola e no marketing que os rodeia, verificando se era colocado em prática, ou se o conhecimento era insuficiente. Adotou-se o método de inquéritos por questionários para recolher a informação necessária e o SPSS (Statistical Package for the Social Sciences) como software para fazer a análise. As escolas escolhidas, encarregados de educação e alunos foram muito recetivos a este questionário, tornando possível uma amostra de 852 inquiridos, dos quais 50,12% são do sexo feminino e 49,88% são do sexo masculino, e cujas idades variam entre os 10 e os 18 anos. De modo geral percebe-se que os inquiridos têm alguma informação sobre alimentação saudável. A maior parte (93,8%) identifica a roda dos alimentos atual e é através da escola (60,2%) e pais/familiares (75,1%) que obtêm o seu conhecimento. No entanto, numa avaliação global resultante de uma análise de clusters, conclui-se que os indivíduos que até possuem algum conhecimento representam um terço dos alunos (38,7%), o que demonstra que ainda há barreiras que têm que se transpor para alertar a população estudantil para este assunto.

Undoubtedly, statistics has become one of the most important subjects in the modern world, where its applications are ubiquitous. The importance of statistics is not limited to statisticians, but also impacts upon non-statisticians who have to use statistics within their own disciplines. Several studies have indicated that most of the academic departments around the world have realized the importance of statistics to non-specialist students. Therefore, the number of students enrolled in statistics courses has vastly increased, coming from a variety of disciplines. Consequently, research within the scope of statistics education has been able to develop throughout the last few years. One important issue is how statistics is best taught to, and learned by, non-specialist students. This issue is controlled by several factors that affect the learning and teaching of statistics to non-specialist students, such as the use of technology, the role of the English language (especially for those whose first language is not English), the effectiveness of statistics teachers and their approach towards teaching statistics courses, students’ motivation to learn statistics and the relevance of statistics courses to the main subjects of non-specialist students. Several studies, focused on aspects of learning and teaching statistics, have been conducted in different countries around the world, particularly in Western countries. Conversely, the situation in Arab countries, especially in Saudi Arabia, is different; here, there is very little research in this scope, and what there is does not meet the needs of those countries towards the development of learning and teaching statistics to non-specialist students. This research was instituted in order to develop the field of statistics education. The purpose of this mixed methods study was to generate new insights into this subject by investigating how statistics courses are currently taught to non-specialist students in Saudi universities. Hence, this study will contribute towards filling the knowledge gap that exists in Saudi Arabia. This study used multiple data collection approaches, including questionnaire surveys from 1053 non-specialist students who had completed at least one statistics course in different colleges of the universities in Saudi Arabia. These surveys were followed up with qualitative data collected via semi-structured interviews with 16 teachers of statistics from colleges within all six universities where statistics is taught to non-specialist students in Saudi Arabia’s Eastern Region. The data from questionnaires included several types, so different techniques were used in analysis. Descriptive statistics were used to identify the demographic characteristics of the participants. The chi-square test was used to determine associations between variables. Based on the main issues that are raised from literature review, the questions (items scales) were grouped and five key groups of questions were obtained which are: 1) Effectiveness of Teachers; 2) English Language; 3) Relevance of Course; 4) Student Engagement; 5) Using Technology. Exploratory data analysis was used to explore these issues in more detail. Furthermore, with the existence of clustering in the data (students within departments within colleges, within universities), multilevel generalized linear models for dichotomous analysis have been used to clarify the effects of clustering at those levels. Factor analysis was conducted confirming the dimension reduction of variables (items scales). The data from teachers’ interviews were analysed on an individual basis. The responses were assigned to one of the eight themes that emerged from within the data: 1) the lack of students’ motivation to learn statistics; 2) students' participation; 3) students’ assessment; 4) the effective use of technology; 5) the level of previous mathematical and statistical skills of non-specialist students; 6) the English language ability of non-specialist students; 7) the need for extra time for teaching and learning statistics; and 8) the role of administrators. All the data from students and teachers indicated that the situation of learning and teaching statistics to non-specialist students in Saudi universities needs to be improved in order to meet the needs of those students. The findings of this study suggested a weakness in the use of statistical software applications in these courses. This study showed that there is lack of application of technology such as statistical software programs in these courses, which would allow non-specialist students to consolidate their knowledge. The results also indicated that English language is considered one of the main challenges in learning and teaching statistics, particularly in institutions where English is not used as the main language. Moreover, the weakness of mathematical skills of students is considered another major challenge. Additionally, the results indicated that there was a need to tailor statistics courses to the needs of non-specialist students based on their main subjects. The findings indicate that statistics teachers need to choose appropriate methods when teaching statistics courses.

The effect of dietary crude protein (CP) and additives on odour flux from broiler litter was investigated using 180 day-old Ross 308 male chicks randomly allocated to five dietary treatments with three replications of 12 birds each. A 5×3 factorial arrangement of treatments was employed. Factors were: diet (low CP, high CP, high CP+antibiotic, high CP+probiotic, high CP+saponin) and age (15, 29, 35 days). Low CP (LCP) and high CP (HCP) diets differed in CP levels by 4.5-5%. The low CP diets were supplemented with L-valine, L-isoleucine, L-arginine, L-lysine, D,L-methionine and L-threonine. The antibiotic used was Zn Bacitracin, the probiotic was a blend of three Bacillus subtilis strains and the saponin came from a blend of Yucca and Quillaja. Odorants were measured from litter headspace using a flux hood and selective ion flow tube mass spectrometry (SIFT-MS). Results were log tranformed and analysed by two-way ANOVA with repeated measures using JMP statistical software v.8, and means were separated by Tukey's HSD test at P<0.05.The results showed that LCP group produced lower flux of dimethyl amine, trimethyl amine, H2S, NH3 and phenol in litter compared to HCP group (P<0.05). Similarly, HCP+probiotic group produced lower flux of H2S (P<0.05) and HCP+saponin group produced lower flux of trimethylamine and phenol in litter compared to HCP group (P<0.05). The dietary treatments tended (P=0.065) to have higher flux of methanethiol in HCP group compared to others. There was a diet x age interaction for litter flux of diacetyl, acetoin, 3-methyl-1-butanol, 3-methylbutanal, ethanethiol, propionic acid and hexane (P<0.05). Concentrations of diacetyl, acetoin, propionic acid and hexane in litter were higher from LCP group compared to all other treatments on d 35 (P<0.05) but not on days 15 and 29. Thus, the low CP diet, Bacillus subtilis based probiotic and Yucca/Quillaja based saponin were effective in reducing the emissions of some key odorants from broiler litter.

Produced water is characterized as one of the most common wastes generated during exploration and production of oil. This work aims to develop methodologies based on comparative statistical processes of hydrogeochemical analysis of production zones in order to minimize types of high-cost interventions to perform identification test fluids - TIF. For the study, 27 samples were collected from five different production zones were measured a total of 50 chemical species. After the chemical analysis was applied the statistical data, using the R Statistical Software, version 2.11.1. Statistical analysis was performed in three steps. In the first stage, the objective was to investigate the behavior of chemical species under study in each area of production through the descriptive graphical analysis. The second step was to identify a function that classify production zones from each sample, using discriminant analysis. In the training stage, the rate of correct classification function of discriminant analysis was 85.19%. The next stage of processing of the data used for Principal Component Analysis, by reducing the number of variables obtained from the linear combination of chemical species, try to improve the discriminant function obtained in the second stage and increase the discrimination power of the data, but the result was not satisfactory. In Profile Analysis curves were obtained for each production area, based on the characteristics of the chemical species present in each zone. With this study it was possible to develop a method using hydrochemistry and statistical analysis that can be used to distinguish the water produced in mature fields of oil, so that it is possible to identify the zone of production that is contributing to the excessive elevation of the water volume.

Atualmente, tem-se vindo a assistir a um aumento da população idosa relativamente á faixa etária dos jovens. Posto isto, surgiu uma maior necessidade de focar a atenção nas condições de vida dos idosos, quer a nível teórico, quer a nível empírico (Mauritti, 2004). O envelhecimento da população é um fenómeno universal, e além de fenómeno coletivo é também um fenómeno individualizado, que decorre desde o nascer e ao qual se juntam alterações fisiológicas, psicológicas e comportamentais (motivos). Neste contexto, o presente estudo teve como objetivo desenvolver, implementar e avaliar a eficácia de um programa de intervenção na cognição e no afeto em grupo. Este grupo foi constituído por cinco idosos do sexo feminino e institucionalizados. O software estatístico IBM SPSS (Statistical Package for the Social Sciencies) versão 20 permitiu analisar e comparar os resultados obtidos através do MMSE (Mini Mental State Examination); PANAS (Positive and Negative Affect Shedule); e a escala de função cognitiva do ESI-55 (Epilepsy Surgery Inventory) antes e após as 9 sessões de intervenção em grupo. Não se verificaram diferenças estatísticas significativas entre o pré e pós teste, havendo resultados tendencialmente significativos em alguns indicadores de afeto negativo, sugerindo uma melhoria ou estabilidade dos valores iniciais. Nos indicadores de afeto positivo verificou-se uma situação algo semelhante. A nível da memória, a estabilidade das queixas apoia a eficácia da intervenção. A nível de outras queixas cognitivas, também não se evidenciaram resultados estatisticamente significativos, mas houve uma tendência para a diminuição das queixas. Assim, considera-se que a continuação de sessões análogas às implementadas poderia ser benéfica (de modo estatisticamente significativo) para os participantes em termos afetivos e cognitivos.

This article aimed at comparing the accuracy of linear measurement tools of different commercial software packages. Eight fully edentulous dry mandibles were selected for this study. Incisor, canine, premolar, first molar and second molar regions were selected. Cone beam computed tomography (CBCT) images were obtained with i-CAT Next Generation. Linear bone measurements were performed by one observer on the cross-sectional images using three different software packages: XoranCat®, OnDemand3D® and KDIS3D®, all able to assess DICOM images. In addition, 25% of the sample was reevaluated for the purpose of reproducibility. The mandibles were sectioned to obtain the gold standard for each region. Intraclass coefficients (ICC) were calculated to examine the agreement between the two periods of evaluation; the one-way analysis of variance performed with the post-hoc Dunnett test was used to compare each of the software-derived measurements with the gold standard. The ICC values were excellent for all software packages. The least difference between the software-derived measurements and the gold standard was obtained with the OnDemand3D and KDIS3D (-0.11 and -0.14 mm, respectively), and the greatest, with the XoranCAT (+0.25 mm). However, there was no statistical significant difference between the measurements obtained with the different software packages and the gold standard (p> 0.05). In conclusion, linear bone measurements were not influenced by the software package used to reconstruct the image from CBCT DICOM data.

Functional brain imaging techniques such as functional MRI (fMRI) that allow the in vivo investigation of the human brain have been exponentially employed to address the neurophysiological substrates of emotional processing. Despite the growing number of fMRI studies in the field, when taken separately these individual imaging studies demonstrate contrasting findings and variable pictures, and are unable to definitively characterize the neural networks underlying each specific emotional condition. Different imaging packages, as well as the statistical approaches for image processing and analysis, probably have a detrimental role by increasing the heterogeneity of findings. In particular, it is unclear to what extent the observed neurofunctional response of the brain cortex during emotional processing depends on the fMRI package used in the analysis. In this pilot study, we performed a double analysis of an fMRI dataset using emotional faces. The Statistical Parametric Mapping (SPM) version 2.6 (Wellcome Department of Cognitive Neurology, London, UK) and the XBAM 3.4 (Brain Imaging Analysis Unit, Institute of Psychiatry, Kings College London, UK) programs, which use parametric and non-parametric analysis, respectively, were used to assess our results. Both packages revealed that processing of emotional faces was associated with an increased activation in the brain`s visual areas (occipital, fusiform and lingual gyri), in the cerebellum, in the parietal cortex, in the cingulate cortex (anterior and posterior cingulate), and in the dorsolateral and ventrolateral prefrontal cortex. However, blood oxygenation level-dependent (BOLD) response in the temporal regions, insula and putamen was evident in the XBAM analysis but not in the SPM analysis. Overall, SPM and XBAM analyses revealed comparable whole-group brain responses. Further Studies are needed to explore the between-group compatibility of the different imaging packages in other cognitive and emotional processing domains. (C) 2009 Elsevier Ltd. All rights reserved.
