Abstract: This is a descriptive study of quantitative approach, developed at the Federal University of Rond?nia located in the Western Amazon. With the aim of analyzing the frequency of visualization of alcoholic content in the Facebook, Instagram and Snapchat, patterns of consumption, reasons that lead them to drink, most used social network and to correlate how often the users are exposed to alcoholic publications, determining if there was an important link between individual drinking practice during the beginning period and six months later. The information was obtained through the application of questionnaires for incoming students of the freshmen semester, in two moments: a period from August to December 2016/2, and, asking the same students again, from March to June 2017/1. 52.8% were males in 2016/2 and 57, 9% of females in 2017/1 with age ranging between 18 and 20 years in both periods. Facebook has proven to be the most used platform among college students. In 2016/2, 63.9% reported seeing alcohol content at Facebook and consuming that substance, comparing to Instagram with 70.4%, and to Snapchat with 74.1%. In 2017/2, academics reporting viewing alcoholic content on Facebook and consuming those alcoholic beverages accounted for 65.8%, compared to Instagram, 74.1% and Snapchat 74.4%. “Celebrating a special occasion with friends” is the most cited reason of why claim to consume alcohol. Therelation between exposure to the alcohol content of the virtual media and the network of friends was found imperceptible to the majority of the students, as they mostly do not consider themselves exposed. Many university students start the graduation already consuming alcoholic substances, which explains why there is no significant change in alcohol consumption between the observed moments, although it was found a relationship between the visualization of alcohol content in social networks and consumption, with greater impact on Snapchat.

Abstract: The in vitro activity of the crude hydroalcoholic extract of the aerial parts of Miconia langsdorffii Cogn. was evaluated against the promastigote forms of L. amazonensis, the causative agent of cutaneous leishmaniasis in humans. The bioassay-guided fractionation of this extract led to identification of the triterpenes ursolic acid and oleanolic acid as the major compounds in the fraction that displayed the highest activity. Several ursolic acid semi-synthetic derivatives were prepared, to find out whether more active compounds could be obtained. Among these ursolic acid-derived substances, the C-28 methyl ester derivative exhibited the best antileishmanial activity.

Abstract: This article refers to the measurement and identification of costs to which a product is submitted, during every stage of its lifecycle. This method for approach and management of costs is called Product Lifecycle and Property Funding. The lifecycle of the product is comprised by different stages of funding where the costs are estimated from the initial idea to its abandonment. With the purpose of evidencing the application of such method, this article deals, through a case study, with its application to the Brazilian publishing industry, offering to it an alternative for the funding of its products (literary titles). The survey may be justified by the lack of works that present an objective conclusion on the validity of using the method, aiming at better managing and reducing the costs in the timeframe of the useful life of the product and achieving competitive advantage. It has been evidenced that the use of the method permits for a company still in the planning phase, the visualization of almost all costs that shall be incurred in the lifecycle of the title, aiming at its better management and maximization of profits for the company, when compared to the traditionally deployed method. The use of the product lifecycle funding method shows to be an important tool for the strategic management of costs as, still in the embryonic phase of the product, it permits the visualization, management and reduction of costs in all phases that the product shall pass through. El presente artículo trata de la mensuración e identificación de los costos a los que se somete un producto durante todas las etapas de su ciclo de vida. Ese método de abordaje y administración de costos se llama Costeo del Ciclo de Vida y Propiedad del Producto. El ciclo de vida del producto se compone de diferentes etapas de costeo donde los costos se estiman desde la idea inicial hasta su abandono. Con el objetivo de poner en evidencia la aplicación de ese método, este artículo aborda, a través de un estudio de caso a su aplicación en la industria editorial brasile a, ofreciéndole a ésta una alternativa para el costeo de sus productos (títulos literarios). El sondeo se puede justificar por la ausencia de trabajos que presentan una conclusión objetiva de la validad de la utilización del método, con vistas a la mejor administración y reducción de los costos en el horizonte de la vida útil del producto y la obtención de ventaja competitiva. Quedó en evidencia que la utilización del método le permite a la empresa aún en la fase de planificación, la visualización de casi la totalidad de los costos

Abstract: this work had, as objective, to verify the influence of refrigeration temperature and bunch age on the conservation and post-harvest quality of the 'prata an?' banana produced in the north of minas gerais, looking towards exportation. 'prata an?' banana tree fruits were used originating from the municipal district of nova porteirinha, mg. the crop was harvested in the 16th, 18th and 20th weeks after the floral emission. from the clusters picked, the second bunches was used, separated in clusters with 5 fruits, washed and weighed (18 kg). soon after, the fruits were wrapped with polyethylene packing of low density with 50mm of thickness under partial vacuum, conditioned in cardboard boxes and distributed on palets. after being wrapped and put on paletes, the fruits were transported to epamig/ctnm, where they were stored in refrigeration chambers at 10 and 12oc with a relative humidity of 95% for a period of 35 days, being analyzed before and after the refrigeration. the storage of 'prata an?' bananas, coming from 16, 18 and 20 week-old bunches, for 35 days at temperatures of 10 and 12oc of did not promote "chilling injury" in the fruits. the 10oc temperature was more effective in preventing the evolution of the coloration of the peel of bananas coming from 18 week-old bunches than the 12oc temperature, while temperatures of 10 and 12oc were equally efficient in the contention of the change of color of bananas coming from 16 week-old bunches. fruits coming from 20 week-old bunches matured non-uniformly during refrigerated storage.

Abstract: O adequado suprimento de N é primordial para se obter alta produtividade de sementes de feij o, entretanto, as respostas a esse nutriente, em sistema de plantio direto, podem variar em fun o da espécie e quantidade de palha. O objetivo do trabalho foi avaliara resposta do feijoeiro à aplica o de N, em sistema de plantio direto, sobre palhada de milho, milheto e braquiária. Foram realizados três experimentos, um para cada espécie de gramínea. O delineamento experimental foi o de blocos casualizados disposto em esquema fatorial 5x2x2, correspondente a cinco doses de N (0, 30, 60, 90, 120 kg ha-1) aplicadas em duas épocas da fase vegetativa (3a e 6a folha trifoliolada) e duas cultivares (IPR Juriti e Pérola), com quatro repeti es. A cultivar IPR Juriti produziu maior número de vagens por planta e apresentou menor massa de 100 sementes em rela o à cultivar Pérola. N o houve diferen a na produtividade do feijoeiro quando a aplica o do N em cobertura foi realizada no estádio de três ou seis folhas trifolioladas. Com base nos resultados obtidos, conclui-se que a produtividade de sementes de feij o aumenta linearmente com as doses de N em sistema de plantio direto sobre palhada de milho. An adequate supply of nitrogen is essential for high yield of common bean seeds; however, the responses to this nutrient in no-tillage systems can vary in function of the species and the amount of straw present. The aim of this research was to evaluate response of the common bean to N in no-tillage systems over maize, millet and Brachiaria brizantha crop residues. Three experiments were conducted, one for each gramineous species. The experimental design was a randomized block in a 5x2x2 factorial scheme, with five N doses (0, 30, 60, 90, 120 kg ha-1), in two distinct stadia during the vegetative development (3rd and 6th trifoliate leaf) and two common bean cultivars (IPR Juriti and Pérola), with four replications. The IPR Juriti produced a greater number of pods per plant and showed lower mass per 100 seeds than Pérola. It did not show variation in bean yield when the sidedressing N application was carried out in the 3rd or 6th trifoliate leaf stadia. Based on the obtained results, one concludes that the seed productivity of common beans increases linearly with N doses in a no-tillage system over maize residues.
Real-Time Monitoring of Climactic and Geotechnical Variables during Landslides on the Slopes of Serra do Mar and Serra da Mantiqueira (São Paulo State, Brazil)  [PDF]

Engineering (ENG) , 2015, DOI: 10.4236/eng.2015.73012
Abstract: The municipalities of Ubatuba, Campos do Jord?o, and S?o José dos Campos are located in the region of S?o Paulo State (Brazil). These municipalities are recognized nationally for having an elevated number of recorded landslides on slopes and embankments. In addition, these municipalities contain multiple areas that are at risk for landslides. Various soil landslides occurred in these municipalities in January 2013, when real-time climactic and geotechnical variables were monitored by automatic rain gauges, humidity sensors and soil temperature and suction devices. The resulting data were used to understand the functions of each variable in the occurrence of land- slides. Analyses of rainfall, humidity and soil temperature were used with field investigations to formulate a hypothesis regarding the predominant rupture mechanism and the role of each monitored variable in the deflagration of the soil landslides that occurred in the three studied municipalities. The geotechnical variable data revealed that both temperature and soil moisture contents played fundamental roles in the deflagration of shallow planar landslides in urban areas. The hourly rain intensity and/or rainfall accumulation for 24 and/or 72 h were responsible for the deflagration of the landslides that occurred in the studied areas, along with the existing anthropic constraints in the risk areas. Significant variations did not occur in the soil suction data during the landslides, principally due to the unsatisfactory sensor precision when reading field suction between 10 and?100 kPA (±25%).
