Sistema de monitoramento da temperatura e umidade em silos graneleiros via radiofrequencia

The use of Information and Communication Technology has grown in most agricultural activities. As a consequence, it has changed the way of thinking and acting of the farmer who wants to establish a more and more competitive market. However, the high costs of acquisition and maintenance of those technologies may be a factor which can inhibit its spread and acceptance, mainly to a large number of small grain Brazilian farmers. In this context, there is a need for innovative solutions that are proper for this universe of farmers. Starting from this premise, this paper presents the development of a low cost prototype to the monitoring process of temperature and humidity values of grains stored in silos, using communication based on wireless technology by radio frequency. Therefore, the economic implications of cost/benefit ratio of innovative application of wireless transmission in the process of thermometry of grains were analysed. The prototype was made of two electronic units, one of acquisition and another one of data reception, as well as computational software, which offered the farmer more precise information for the control of aeration. By means of stability, integrity and reliability tests of data transmission via radio, using low cost electronic components, the development system can be considered as potentially viable. It presented the difference regarding the wireless communication via radio in the process of grains thermometry, providing mobility, reducing cabling costs and maintenance, and also offering an easy system expansion; it was also appropriate to temperature and humidity monitoring in grain silos; and revealed operational viability, besides the low cost development when compared to similar products available in the Brazilian market.

Aplicação do valor presente ajustado (APV) para avaliação do fluxo de caixa de uma empresa do setor automotivo no sistema inovar auto

The automobile industry shows relevance inside the Brazilian industrial scenario since it contributes with the development of a significant chain of supply, distributors, workshops, publicity agencies and insurance companies in the internal market, aside from being one of the five biggest worldwide market. Thereby, the federal government decreed in Dec, 17th 2012 by Law nº 12.715 the Inovar-Auto Program. As the Adjusted Present Value (APV) is highly recommended, although not yet widespread to public politics of tax reduction, this work intends to apply the APV method on the cash flow analysis of an automobile sector's company, which has recently installed in national territory and wants to rely with governmental incentives proposed by Inovar-Auto Program. The developed work evaluates the company's current cash flow stochastically from mathematical modeling of variables such as price, demand and interest rate through probability distributions with the assist of Crystal Ball software, a Microsoft Excel Add-in, generating different scenarios from Monte Carlo Simulation. As results probabilities situations have been evaluated until the end of the Inovar-Auto's conducted period, in 2017. Beside APV others indicator such as Internal Rate of Return (IRR) and payback period were estimated for the investment project. For APV a sampling distribution with only 0.057% of risk, IRR of 29% were obtained and estimated project payback period was 4.13 years

Software para estimativa do custo operacional de máquinas agrícolas - MAQCONTROL

A seleção e a otimização de sistemas mecanizados são os principais objetivos da mecanização racional. Não é suficiente uma compra adequada do maquinário agrícola se sua utilização não for controlada em aspectos operacionais e financeiros. Neste trabalho, é descrito o desenvolvimento de software para estimativa do custo operacional de máquinas agrícolas (MAQCONTROL), utilizando o ambiente de desenvolvimento Borland Delphi e o banco de dados Firebird. Os custos operacionais foram divididos em fixos e variáveis. Nos custos fixos, foram estimadas as despesas com depreciação, juros, alojamento e seguros. Nos custos variáveis, foi dada ênfase aos custos de manutenção como: óleos lubrificantes, filtros, pneus, graxa, combustível, pequenos reparos e troca de peças. Os resultados demonstraram a eficiência do software para os objetivos propostos. Assim, o MAQCONTROL pode ser uma importante ferramenta no processo de administração rural, pois reduz os custos da informação e agiliza a determinação precisa dos custos operacionais de máquinas agrícolas.

Assessment of physiological potential of cucumber seeds using the software Seedling Vigor Imaging System® (SVIS®)

The software Seed Vigor Imaging System (SVIS®), has been successfully used to evaluate seed physiological potential by automated analyses of scanned seedlings. In this research, the efficiency of this system was compared to other tests accepted for assessing cucumber (Cucumis sativus L.) seed vigor of distinct seed lots of Supremo and Safira cultivars. Seeds were subjected to germination, traditional and saturated salt accelerated aging, seedling emergence, seedling length and SVIS analyses (determination of vigor indices and seedling growth uniformity, lengths of primary root, hypocotyl and whole seedlings). It was also determined whether the definition of seedling growth/uniformity ratios affects the sensitivity of the SVIS®. Results showed that analyses SVIS have provided consistent identification of seed lots performance, and have produced information comparable to those from recommended seed vigor tests, thus demonstrating a suitable sensitivity for a rapid and objective evaluation of physiological potential of cucumber seeds. Analyses of four-days-old cucumber seedlings using the SVIS® are more accurate and growth/uniformity does not affect the precision of results.

Tratamiento informativo de la delincuencia de menores en la prensa canaria

[ES] La delincuencia de menores constituye un fenómeno social que sensibiliza y moviliza a la opinión pública y, especialmente, a los medios de comunicación. La prensa, en este sentido, adquiere la responsabilidad de exponer este discurso informativo en sus dimensiones reales y debe hacer todo lo posible, para que los derechos y deberes de los menores infractores sean conocidos y discutidos por el público receptor, y formando de este modo, un auténtico debate público en la agenda política insular. Los acontecimientos o sucesos violentos protagonizados por menores, o en los que estos resultan víctimas, impactan porque generan conmoción social y garantizan la atención mediática. La selección informativa efectuada por los rotativos de tirada provincial ha coadyuvado a construir en la sociedad canaria una percepción deformada sobre el sistema de gestión de la justicia penal juvenil, influyendo sobremanera en actitudes y comportamientos tales como el surgimiento generalizado de las oposiciones vecinales contra la instalación, construcción o reforma de los centros de ejecución de medidas judiciales.

Actualización, consolidación, migración y contingencia de un entorno hardware y software para la gestión de bases de datos

[ES]El objetivo de este Trabajo es el de actualizar un entorno de gestión de bases de datos existente a la versión 11.2 del software de bases de datos Oracle y a una plataforma hardware de última generación. Se migran con tiempo de parada cero varias bases de datos dispersas en distintos servidores a un entorno consolidado de dos nodos dispuestos en alta disponibilidad tipo "activo-activo" mediante Oracle RAC y respaldado por un entorno de contingencia totalmente independiente y sincronizado en tiempo real mediante Oracle GoldenGate. Se realiza un estudio del entorno actual y, realizando una estimación de crecimiento, se propone una configuración de hardware y software mínima para implementar con garantías de éxito los requerimientos del entorno de gestión de bases de datos a corto y medio plazo. Una vez adquirido el hardware, se lleva a cabo la instalación, actualización y configuración del Sistema Operativo y el acceso redundado de los servidores a la cabina de almacenamiento. Posteriormente se instala el software de clúster de Oracle, el software de la base de datos y se crea una instancia que albergará los esquemas requeridos de las bases de datos a consolidar. Seguidamente se migran los esquemas al entorno consolidado y se establece la replicación de éstos en tiempo real con la máquina de contingencia usando en ambos casos Oracle GoldenGate. Finalmente se crea y prueba un esquema de copias de seguridad que incluye copias lógicas y físicas de la propia base de datos y de archivos de configuración del clúster a partir de los cuales será posible restaurar el entorno completamente.
