Qualidade fisiológica de sementes de Moringa oleifera lam. por meio da análise de imagens

Several tests that evaluate the quality of seeds are destructive and require time, which is considered long and expensive in the processes that involves the production and marketing of seed. Thus, techniques that allow reducing the time related to assess the quality of seed lots is very favorable, considering the technical, economic and scientific point of view. The techniques images of seed analyzed both by X-ray such as digital images, represent alternative for this sector, and are considered reproducible and fast, giving greater flexibility and autonomy to the activities of production systems. Summarily, the objective was to analyze the internal morphology of seeds of this species through x-rayed images and the efficiency of weed seed area increased during soaking through image analysis and compare them with the results of germination tests and force the evaluation of physiological seed quality. For X-ray tests, the seeds were exposed for 0.14 seconds at radiation 40kV and 2.0 mAs. Were analyzed images using the ImageJ program and subsequently put to germinate in B.O.D chamber at 27 ° C, in which there was the comparison of results for germination. To determine the test area increase (% IA), seeds were used with and without seed coat, maintained the B.O.D chamber at 15 ° to 20 ° C, the seeds were photographed before and after the soaking period, the results were compared to the germination rates. For the X-ray test, it was observed that seeds with empty area greater than 20%, showed a higher percentage of abnormal seedlings. And the area increment analysis showed that it is possible to rank the batch after 8 hours of imbibition at 15 ° C according to the germination and vigor tests

Diagnóstico da comercialização de produtos da medicina popular em feiras livres do semiárido do Rio Grande do Norte: avaliações socioeconômicas e sanitárias, com proposta de legislação específica

Historically, man has empirically acquired knowledge about the therapeutic applications of extracted elements of the natural environment in which belonged. Such knowledge over time culminated in the formation of traditional health systems. Among its features, the use of bioactive plant species - medicinal plants - stands out for its efficiency and high popular acceptance. Despite its importance for public health, the population still has in the open-air fairs the main source for the acquisition of the species used. In these spaces, the trade generally occurs informally, under unfavorable conditions to the quality of the products and to the financial sustainability of the business. In this context, this study aimed to characterize the socioeconomic, cultural and sanitary aspects related to the trade of medicinal plants in municipalities of a semiarid region of Rio Grande do Norte, and additionally, proposing a specific legislation to the activity. Socioeconomic data were collected through on-site interviews, guided by structured form. The observations about the hygienic and sanitary adequacy of physical facilities and practices employed at the point of sale /environment were conducted and recorded with the use of assessment tool developed for use in open markets. The adequacy of medicinal plants to consumption was determined by microbiological analysis. The activity was carried out by individuals who are aged between 21 and 81 years of age, low educational level and low-income, predominantly males. The data showed a tendency to extinction of the activity in all the districts studied. It was observed in all the fairs studied hygiene and sanitation inadequacies that characterized very high health risk, representing in this way, the high probability of Food Transmitted Diseases outbreaks Such conditions were reflected in the high percentage of inadequacy to the consumption of the analyzed medicinal plants samples, illustrating the potential health risk to consumers. To contribute to the correction of hygiene and sanitation inadequacies observed in the studied open-air fairs, educational interventions were made to the training of traders in Good Practices. As a complement, was drafted a specific legislation for the marketing of folk medicine's products in open-air fairs. Such actions, products and its developments will contribute significantly to improving the quality of products available to the population and the preservation of activity, potentially reducing the risks to public health.

Mecanismos de transmissão de preços e parcelas de mercado: uma análise sobre as exportações brasileiras de manga

Climate and environmental conditions allowed Brazil to become one of the largest producers of tropical fruits in the world. The São Francisco Valley, over the years, has emerged as the main fruit-producing region of the country, especially mangos and grapes. The mango, which is produced in this region, has reached a good international position, especially in European and American markets. However, the domestic price has absorbed more and more the impact of fluctuations in the international market expectations affecting the production and marketing of producers. The objective of the study is to analyze the transmission ratio of export prices of the mango, with the American market prices and the European Union in the period from 2003 to 2013. It is intended also to analyze the factors affecting the fluctuations of exports Brazilian mango for the main import markets. To achieve the proposed objectives, we used, in the methodology, the autoregressive vector model, in order to find the price transmission mechanism and the mechanisms of impacts through the impulse response function. We also used, the Constant Market Share model, in order to observe the importance of the effects competitiveness, destination, and growth in world trade on the changes of Brazilian mango exports in the period. The data used were obtained from the database of the Ministry of Development and Foreign Trade - MIDIC and FAOSTAT (Food and Agriculture Organization of the United Nations). Among the results, it was found that the Brazilian domestic prices are influenced by the US market price, and that price shocks promoted this market can impact on the growth of the internal prices for several months. It was noted also that the competitiveness effect accounted for the largest portion of the effective growth of Brazilian exports, in other word, the country has improved its competitiveness among the other exporting countries.

El debate de la medición digital: Una piedra en el camino para la consolidación de la inversión publicitaria

La llegada de ingresos provenientes de la distribución digital de la prensa continúa siendo reducida. A pesar de su volumen de lectores, el aumento de posibilidades dentro de los formatos publicitarios, la capacidad de medición del retorno de la inversión que ofrece el medio digital y la aparente unificación en la medición de audiencia que desde 2012 está presente en el mercado. De esta manera, los diferentes medios continúan sin conseguir rentabilizar la migración digital que cada día conlleva continuos gastos sin ofrecer beneficios. La audiencia como moneda de cambio en la comercialización de espacios publicitarios ha perdido todo su valor, pese al retorno de la inversión que ofrece. Este trabajo describe esta problemática y los cambios realizados antes y después del «fin del debate de la medición de audiencias» con el objetivo de poner en valor la venta de los espacios publicitarios digitales. En concreto se analiza el caso de los diarios digitales por su elevada lectura y sus escasos ingresos.

Iowa Highway Programs, Finances, and Progress, 1952

(a) Iowa has a total of 101,620 miles of rural roads, both primary and secondary. (b) On January 1, 1952, a total of 71,493 miles of these rural roads were surfaced - mostly with gravel and crushed stone. (c) Additional roads are being surfaced at the rate of 2662 miles per year. (d) Iowa's highway program provides for a surfaced road to every reasonably located rural home and a paved or other type of dustless surface on all primary roads. (e) Iowa's highway funds come 26.0 per cent from property taxes, 63.5 per cent from road use taxes, 10.5 per cent from Federal aid. (f) Annual income under present laws, available for highway construction, is approximately For primary roads------------------$23,000,000 For secondary roads---------------- 41,967,000 (g) Iowa's highway improvements are being paid for as built. No new bonds are being issued. (h) The surplus of farm to market road funds created during and immediately following the War have now been placed under contract, with only a minimum working balance remaining in the fund. (i) Iowa's highway program was estimated to cost $945,000,000 and to require twenty years to build, by the 1948 Legislative Committee. This estimate would now have to be increased due to price increases and higher required standards. These are the highlights of Iowa's highway program. The details will follow in succeeding paragraphs.

Avaliação da política de segurança alimentar implementada através dos restaurantes populares do Rio Grande do Norte

This survey has to general objective to evaluate the Food Safety Policy implemented by Restaurantes Populares do Rio Grande do Norte. The survey is qualitative of type exploratory and descriptive. The universe of survey is all Units of Food and Nutrition (UAN) of the Restaurantes Populares do Rio Grande do Norte. To collects of data were used two instruments: interview and form. The interviews were intended to analyze the four axes of the Food Safety: access, food quality, production and marketing of food and organizational arrangement. The form was used to check the quality of nutrition and sanitary-hygienic food served. We used two types of forms: a spreadsheet with the weekly menu and the portions served to verify that the meals serve the nutritional needs proposed by the program; and the check-list of ANVISA to verify the sanitary-hygienic conditions in each unit. Through the survey data and analyses made observe that the access category have some problems such as lack of registration, lack of advertising of Restaurants and wastage of public resources, making policy that should be of included in a policy of exclusion. In the nutritional aspect there is neglect on the daily nutritional goal, because it is not accomplished nutritional analysis of menu offered, the nutritionists do not know what should be the nutritional value of meals served; in the hygienic-health aspect trough the problems identified is concludes that there is no guarantee of food quality hygienic-sanitary, committing the program as a Food Safety Program. About the production and marketing of food is observed some problems as: the goal of sale of meals is not achieved in full, the purchase of genres does not stimulate the local economy, nor generates jobs and income, and inefficient performance of the MEIOS's supervision. In the analysis of organizational arrangement is concluded that the partnerships are beneficial, despite some negative points, therefore, are these partnerships the problems of non-compliance, as both the MEIOS and Nutriti of important criteria established in the partnership. Therefore, it is understood that the Programa Restaurantes Populares in its original formulation is proposed to be a food safety policy, but has some problems that impossible to meet its goal, making it unprofitable like Food Safety Policy

Evaluating a School Community Linked Physical Activity Intervention Programme: a Multi-level Analysis.

Previous research has highlighted the importance of positive physical activity (PA) behaviors during childhood to promote sustained active lifestyles throughout the lifespan (Telama et al. 2005; 2014). It is in this context that the role of schools and teachers in facilitating PA education is promoted. Research suggests that teachers play an important role in the attitudes of children towards PA (Figley 1985) and schools may be an efficient vehicle for PA provision and promotion (McGinnis, Kanner and DeGraw, 1991; Wechsler, Deveraux, Davis and Collins, 2000). Yet despite consensus that schools represent an ideal setting from which to ‘reach’ young people (Department of Health and Human Services, UK, 2012) there remains conceptual (e.g. multi-component intervention) and methodological (e.g. duration, intensity, family involvement) ambiguity regarding the mechanisms of change claimed by PA intervention programmes. This may, in part, contribute to research findings that suggest that PA interventions have had limited impact on children’s overall activity levels and thereby limited impact in reducing children’s metabolic health (Metcalf, Henley & Wilkin, 2012). A marked criticism of the health promotion field has been the focus on behavioural change while failing to acknowledge the impact of context in influencing health outcomes (Golden & Earp, 2011). For years, the trans-theoretical model of behaviour change has been ‘the dominant model for health behaviour change’ (Armitage, 2009); this model focusses primarily on the individual and the psychology of the change process. Arguably, this model is limited by the individual’s decision-making ability and degree of self-efficacy in order to achieve sustained behavioural change and does not take account of external factors that may hinder their ability to realise change. Similar to the trans-theoretical model, socio-ecological models identify the individual at the focal point of change but also emphasises the importance of connecting multiple impacting variables, in particular, the connections between the social environment, the physical environment and public policy in facilitating behavioural change (REF). In this research, a social-ecological framework was used to connect the ways a PA intervention programme had an impact (or not) on participants, and to make explicit the foundational features of the programme that facilitated positive change. In this study, we examined the evaluation of a multi-agency approach to a PA intervention programme which aimed to increase physical activity, and awareness of the importance of physical activity to key stage 2 (age 7-12) pupils in three UK primary schools. The agencies involved were the local health authority, a community based charitable organisation, a local health administrative agency, and the city school district. In examining the impact of the intervention, we adopted a process evaluation model in order to better understand the mechanisms and context that facilitated change. Therefore, the aim of this evaluation was to describe the provision, process and impact of the intervention by 1) assessing changes in physical activity levels 2) assessing changes in the student’s attitudes towards physical activity, 3) examining student’s perceptions of the child size fitness equipment in school and their likelihood of using the equipment outside of school and 4) exploring staff perceptions, specifically the challenges and benefits, of facilitating equipment based exercise sessions in the school environment. Methodology, Methods, Research Instruments or Sources Used Evaluation of the intervention was designed as a matched-control study and was undertaken over a seven-month period. The school-based intervention involved 3 intervention schools (n =436; 224 boys) and one control school (n=123; 70 boys) in a low socioeconomic and multicultural urban setting. The PA intervention was separated into two phases: a motivation DVD and 10 days of circuit based exercise sessions (Phase 1) followed by a maintenance phase (Phase 2) that incorporated a PA reward program and the use of specialist kid’s gym equipment located at each school for a period of 4 wk. Outcome measures were measured at baseline (January) and endpoint (July; end of academic school year) using reliable and valid self-report measures. The children’s attitudes towards PA were assessed using the Children’s Attitudes towards Physical Activity (CATPA) questionnaire. The Physical Activity Questionnaire for Children (PAQ-C), a 7-day recall questionnaire, was used to assess PA levels over a school week. A standardised test battery (Fitnessgram®) was used to assess cardiovascular fitness, body composition, muscular strength and endurance, and flexibility. After the 4 wk period, similar kid’s equipment was available for general access at local community facilities. The control school did not receive any of the interventions. All physical fitness tests and PA questionnaires were administered and collected prior to the start of the intervention (January) and following the intervention period (July) by an independent evaluation team. Evaluation testing took place at the individual schools over 2-3 consecutive days (depending on the number of children to be tested at the school). Staff (n=19) and student perceptions (n = 436) of the child sized fitness equipment were assessed via questionnaires post-intervention. Students completed a questionnaire to assess enjoyment, usage, ease of use and equipment assess and usage in the community. A questionnaire assessed staff perceptions on the delivery of the exercise sessions, classroom engagement and student perceptions. Conclusions, Expected Outcomes or Findings Findings showed that both the intervention (16.4%) and control groups increased their PAQ-C score by post-intervention (p < 0.05); with the intervention (17.8%) and control (21.3%) boys showing the greatest increase in physical activity levels. At post-intervention, there was a 5.5% decline in the intervention girls’ attitudes toward PA in the aesthetic subdomains (p = 0.009); whereas the control boys had an increase in positive attitudes in the health domain (p = 0.003). No significant differences in attitudes towards physical activity were observed in any other domain for either group at post-intervention (p > 0.05). The results of the equipment questionnaire, 96% of the children stated they enjoyed using the equipment and would like to use the equipment again in the future; however at post-intervention only 27% reported using the equipment outside of school in the last 7 days. Students identified the ski walker (34%) and cycle (32%) as their favorite pieces of equipment; with the single joint exercises such as leg extension and bicep/tricep machine (<3%) as their least favorite. Key themes from staff were that the equipment sessions were enjoyable, a novel activity, children felt very grown-up, and the activity was linked to a real fitness experience. They also expressed the need for more support to deliver the sessions and more time required for each session. Findings from this study suggest that a more integrated approach within the various agencies is required, particularly more support to increase teachers pedagogical content knowledge in physical activity instruction which is age appropriate. Future recommendations for successful implementation include sufficient time period for all students to access and engage with the equipment; increased access and marketing of facilities to parents within the local community, and professional teacher support strategies to facilitate the exercise sessions.

Fixation du prix de vente des exploitations agricoles québécoises: comparaison entre fermes laitières et autres types de production

L’écart croissant entre les valeurs marchande et économique des exploitations agricoles québécoises complexifie le processus de transfert des fermes à la prochaine génération. La capacité de payer limitée des repreneurs et les besoins de retraite des cédants restreignent la marge de manoeuvre nécessaire afin de déterminer un prix de vente de l’entreprise adéquat. La présente étude vise à analyser les déterminants du prix de vente des fermes et montre que dans notre échantillon, le prix est significativement corrélé avec les besoins de retraite nets des cédants et de façon moins significative, avec la valeur économique des fonds propres de l’entreprise. Les considérations financières semblent éclipser les aspects humains et d’importants compromis sont réalisés des deux côtés de la transaction en vue d’assurer la continuité de l’entreprise. L’influence d’intervenants externes à l’entreprise entre également en ligne de compte dans la fixation du prix, ce qui implique que la décision ne découle pas uniquement d’une négociation entre cédants et repreneurs. De façon générale, les fermes laitières semblent confrontées aux mêmes défis que les autres types de production quant à la fixation de leur prix de vente, ce qui suggère que la problématique soit davantage une question de gestion plutôt qu’une question spécifique au secteur. À moins d’un rétrécissement de l’écart entre la valeur marchande des actifs et leurs capacités à générer des revenus, la fixation du prix de vente de plusieurs fermes du Québec risque d’être encore plus contraignante à l’avenir.

Climate changes and mycotoxins: two risk factors associated!

Many species of fungi produce bioactive compounds called mycotoxins. These compounds are produced by filamentous fungi and can contaminate food, feeds and specific indoor environments resulting in high economic losses. Severe health problems and death have been related with mycotoxins exposure through the consumption of several food commodities. There are many factors involved in mycotoxin production by fungi but climate is the most important. Thus, when changes in the weather occur, mycotoxins production will be affected. We looked for articles that were available in scientific databases, written in English and that mention in the title and/or abstract the combined terms fungi and climate change and also mycotoxins and climate change.

Cultivo de microalgas para produção de biossurfactantes

Há uma crescente procura por alimentos mais saudáveis e seguros para atender uma população cada vez maior e mais exigente. Nos últimos anos o interesse por surfactantes de origem microbiana tem aumentado significativamente em decorrência de serem naturalmente biodegradáveis diminuindo assim o impacto ambiental. Uma grande variedade de microorganismos produz biossurfactantes, sendo que o tipo, a quantidade e a qualidade do biossurfactante são influenciados pelos constituintes do meio, tais como, fontes de carbono, nitrogênio e sais inorgânicos, além das condições de cultivo, como pH, temperatura, agitação e disponibilidade de oxigênio. Os biossurfactantes são metabólitos microbianos de superfície ativa que apresentam uma vasta aplicação no setor industrial. Os objetivos deste trabalho foram selecionar microalgas com potencial para produzir biossurfactantes e estudar a produção por microalgas em diferentes fotobiorreatores e condições nutricionais. O trabalho foi dividido em quatro etapas: 1) cultivo autotrófico e mixotrófico de microalgas para produção de biossurfactantes; 2) Seleção de microalgas para produção de biossurfactantes; 3) Produção de biossurfactantes por microalgas em diferentes fotobiorreatores e 4) Cultivo outdoor da microalga marinha Tetraselmis suecica OR para produção de biossurfactantes. Na primeira etapa Spirulina sp. LEB-18, Synechococcus nidulans LEB-25, Chlorella vulgaris LEB-106, Chlorella minutissima LEB-108 e Chlorella homosphaera foram cultivadas com glicose (cultivo mixotrófico). Spirulina sp. LEB-18 apresentou concentrações máximas de biomassa (2,55 g.L-1 ) quando foi utilizada 5 g.L-1 de glicose no meio de cultivo. A tensão superficial dos meios das microalgas foi reduzida de 70 para 43 mN.m-1 para as microalgas estudadas utilizando glicose como fonte de carbono. Resultados da segunda etapa mostraram que a microalga Scenedesmus sp. 3PAV3 apresentou valor de atividade emulsificante óleo em água (AE o/a) superior (339,8 UE.g-1 ) ao encontrado para as demais microalgas. Os menores valores de tensões superficiais variaram de 27,4 a 31,2 mN.m-1 . Na terceira etapa verificou-se que a microalga Chlorella sp. PROD1 apresentou valor de AE o/a semelhante (258,2 UE g -1 ) ao encontrado para o emulsificante comercial lecitina de soja (257,0 UE g -1 ) e ambas as microalgas estudadas alcançaram valores de tensões superficiais abaixo de 30 mN.m -1 . Na última etapa, Tetraselmis suecica OR cultivada em fotobiorreator do tipo Green Wall Panel apresentou menores valores de tensões superficiais para cultura com limitação de nitrogênio. Os resultados demonstraram a potencialidade das microalgas estudadas na produção de biossurfactantes, tanto pela redução da tensão superficial e interfacial, como pelo aumento da atividade emulsificante, confirmando uma possível aplicação como emulsificante, detergente, lubrificante, estabilizante, entre outras.

Efeitos tóxicos induzidos pelos nanomateriais Fulereno (C60) e Nanoprata no Poliqueto Laeonereis Acuta (Nereididae) e nas comunidades bacterianas que habitam sua superfície corporal

O fulereno (C60) pertence a uma família de nanomateriais (NM) constituída exclusivamente de átomos de carbono, sendo encontrado na forma de suspensão na água (nC60). A nanoprata (nAg) possui um excepcional e amplo espectro bactericida e um custo de fabricação relativamente baixo. No entanto, pouco se sabe a respeito dos eventuais efeitos tóxicos induzidos por estes NM em organismos estuarinos. O poliqueto Laeonereis acuta tem o muco colonizado por comunidades bacterianas. Há registros de que L. acuta apresenta um gradiente corporal para concentração de EAO e capacidade antioxidante total. Neste estudo, os poliquetos foram expostos in vivo durante 24 horas ao nC60 e à nAg, separadamente. Após isso, as unidades formadoras de colônias (UFC) bacterianas foram contadas e pesadas, além de serem realizadas diversas medições bioquímicas nos poliquetos e nas bactérias. Os números de UFC bacterianas expostas ao nC60 foi menor na concentração de 0.01mg/L e os números de UFC bacterianas expostas à nAg foram similares aos dados de biomassa, diminuindo na maior concentração (1.0 mg/L) (p<0.05). A capacidade antioxidante contra radicais peroxil em homogeneizados bacterianos expostos ao nC60 foi menor na concentração de 0.1mg/L quando comparado ao controle (p<0.05). A região anterior apresentou menor capacidade antioxidante (p<0.05) nos poliquetos expostos a 1.0 mg/L, quando comparado ao controle. Os poliquetos expostos à nAg apresentaram menor capacidade antioxidante na região posterior na concentração de 1.0 mg/L quando comparado ao controle (p<0.05). O conteúdo de peróxidos lipídicos (TBARS) foi reduzido na região anterior dos poliquetos expostos nas duas menores concentrações ( 0.01 e 0.1 mg/L) de nC60 (p<0.05). Na região corporal posterior, somente os organismos expostos a maior concentração de nC60 (1.0 mg/L) mostraram aumento na concentração de TBARS quando comparado ao grupo controle (p<0.05). A atividade da enzima glutationa-Stransferase (GST) foi aumentada (p<0.05) na região média e posterior dos poliquetos expostos a 0.1 mg/L de nC60. Como conclusões pode se dizer que os dois NM induziram efeitos tóxicos ainda numa situação (escuridão) onde o fulereno não é fotoexcitado. O aumento na produção e comercialização de produtos com NM levanta a questão dos riscos ambientais associados ao desenvolvimento da nanotecnologia.

LA GERENCIA DE LOS SERVICIOS ESPECIALIZADOS DE INFORMACIÓN CONCEBIDOS COMO UNA EMPRESA AMPLIADA

El concepto de empresa ampliada, dentro de la gerencia de servicios, permite analizar las funciones y objetivos de las bibliotecas, aprovechar oportunidades y superar limitaciones que tradicionalmente han sido motivo de estancamiento. La economía de servicios y los avances de la tecnología de los sistemas de información, exigen a las bibliotecas un papel más agresivo en cuanto a su identificación con la misión, visión y objetivos de las organizaciones a las cuales pertenecen. Aplicar el concepto de empresa ampliada, podría permitir a las bibliotecas lograr los beneficios propios de una red de valor, en contraposición de las desventajas de un trabajo aislado de sus clientes internos, externos y finales.
