<div class="section abstract"><div class="htmlview paragraph">In automotive industry launches, vehicle dynamics play a key role in the success of each project, as it must make that product recognizable as belonging to a particular automaker and must also reflect what the customer expects from the product itself. So, during the initial phases of the project, a study of reference vehicles begins experimentally, building a robust basis for the definition of performance targets, using not only objective data but also a subjective evaluation, resulting in a technical specification document with most relevant points. Thus, with a known and measured reference vehicle, a virtual model should be created to serve as basis for the development of the new vehicle. In this first moment, the reference model must faithfully represent the values measured on the track, ensuring a robust comparison basis for the future development. The numerical-experimental correlation occurs at several levels, from the correlation of suspension and steering kinematics and compliance to full vehicle’s dynamic behavior, in this case, lateral dynamics. With a correlated multibody model, two steps are taken, converting it to the real-time environment and, in other to derive the model that will represent the new vehicle. With this new model, the same maneuvers will be performed to compare and from that point on, new solutions can be explored to reach the project targets, after this phase the model of the new vehicle is also converted to the real-time environment, thus allowing the simulation to occur in real-time on the dynamic simulator. Once in the simulator, the driver will evaluate the reference model and adjust the motion cueing, that is a platform response algorithm to adjust the driver's subjective perception of the model since objectively it responds according to the physical measurement, the same motion cueing must be applied on the new vehicle model.</div></div>

The objective of this research is to design, develop and test the InP based multichannel transceivers dedicated for application in WDM access systems. The transmitters are making use of DBR lasers and Mach-Zehnder modulators. The satisfying parameters of transceivers were obtained like low threshold current and good side mode suppression ratio.

Resumo: A água é fundamental à manutenção da vida e sua qualidade depende das condições naturais e da ocupação do solo na bacia hidrográfica. Ela contém, geralmente, diversos componentes, que provêm do próprio ambiente natural ou foram introduzidos a partir de atividades humanas. Para caracterizar uma água, são determinados diversos parâmetros, os quais representam as suas características físicas, químicas e biológicas. Esses parâmetros são indicadores da qualidade da água e constituem impurezas quando alcançam valores superiores aos estabelecidos para determinado uso. Este trabalho teve como objetivo avaliar a qualidade físico-química da água do córrego dos Cesários - Anápolis/GO e sua capacidade de dissolução de contaminantes. O citado córrego recebe um resíduo proveniente da lavagem de filtros de uma Estação de Tratamento de Água (ETA). Esse resíduo deságua no córrego sem nenhum tratamento prévio. As análises foram realizadas no Laboratório de Geoquímica da Universidade de Brasília. Os parâmetros avaliados foram pH, Condutividade Elétrica (Ce), Ca (Cálcio), Mg (Magnésio), Na (Sódio), K (Potássio), NH3 (Nitrito), F (Flúor), Cl (Cloro), NO3 (Nitrato), PO4 (Fosfato), SO4(Sulfato), Alcalinidade, Fe (Ferro), Si (Silício) e Alumínio (Al). De acordo com a caracterização físico-química efetuada nesse trabalho, pode-se dizer que a qualidade da água do Córrego dos Cesários precisa ser melhorada e devem ser tomadas as devidas providências para evitar que continue o despejo de resíduos, tanto por parte da ETA de Anápolis quanto por esgotos domésticos que margeiam seu curso. Caso contrário, as alterações na classe do rio podem trazer prejuízos não só ao meio ambiente, mas também à saúde pública da população em geral. Palavras-Chave – Caracterização. Contaminantes.

To identify genes that are up and down-regulated by water deficit in sugarcane we used the macroarray methodology and the expression level of 3 575 independent sugarcane cDNAs was measured by hybridization with RNA extracted from plants submitted to mild, moderate and severe water deficit. We identified approximately 1 670 differentially expressed genes from which 62 % were up-regulated by different stress-conditions, whereas many repressed genes were exclusive for each time-point. Analysis of similarity showed that approximately 24 % of the differentially expressed genes shared homology with proteins involved in different processes such as signal transduction, hormone metabolism, photosynthesis, transcription and stress response. Transcripts with no known function accounted for approximately 39 % and those without similarity represented 36 % of the sequences. Five genes analyzed by RT-PCR confirmed the macroarray results.

Due to the small size of the seed, canola ( Brassica napus or Brassica campestris ) offers different challenges in the harvest and the subsequent post-harvest operations. Often, in Argentina, farmers do not have enough permanent storage capacity so they overcome this deficit with the use of hermetic plastic bags (silobags). The objectives of this work were: 1) Determine the feasibility of the bagging and extraction processes of canola. 2) Monitoring the condition of canola by periodic measurement of carbon dioxide (CO2), temperature, moisture content (m.c.) and quality of the grain. Thirty tonnes of canola with initial m.c. of 6 % were stored in a silobag in the southeast of the Buenos Aires province, Argentina. The storage period was extended from November 2008 to November 2009. The variables measured every two weeks were CO 2 concentration, m.c. and grain quality parameters, such as foreign matters, fat acidity and fat content. The temperature and relative humidity (r.h.) of the interstitial air inside the bag and of the ambient air were also recorded with a frequency of one hour. It was observed that, even the size and characteristics of the canola seeds, it was possible to perform the bagging and extraction operations of canola seeds without problems. The r.h. in the interstitial air remained below 50% along the entire storage period. The temperature of the grain inside the bag followed the monthly average ambient temperature. The CO 2 concentration ranged from 1 to 8 %, indicating low to moderate biological activity in the grain mass. The m.c., foreign matters and fat values remained unchanged throughout the storage period. The fat acidity increased during storage in 0.7 % points, reaching a final value of 1.4 %, but did not represent a commercial quality loss. It was concluded that under the conditions of temperature and m.c. evaluated in this study it is possible to store canola in hermetic plastic bags without commercial quality deterioration. Keywords : Silobags, CO 2 concentration, Interstitial air, Moisture content, Fat acidity.

O objetivo deste trabalho foi caracterizar o consumo de energia na implantação e condução da cultura do Crambe abyssinica Hochst, em sistema de plantio direto, na Fazenda Experimental Lageado, pertencente à Faculdade de Ciências Agronômicas - UNESP, localizada no município de Botucatu - SP. Avaliando a sustentabilidade do sistema, estimaram-se, a eficiência energética e a cultura do crambe. Para o levantamento dos componentes da estrutura de dispêndios, foram utilizados coeficientes energéticos preconizados em literaturas especializadas. As estruturas de dispêndios energéticos por tipo, fonte e forma demonstraram que a energia indireta participou com 65,03%; as fontes industrial, fóssil e biológica representaram 68,80%, 23,67% e 11,30%, respectivamente. Quanto às formas em que se apresentaram, os fertilizantes químicos contribuíram com 44,31%, e o óleo diesel, com 23,04%, totalizando 67,35% do dispêndio energético, evidenciando a dependência do sistema das fontes energéticas industriais e fósseis. A eficiência da cultura encontrada foi de 9,98, apontando que, para cada unidade calórica aplicada na produção do crambe, o retorno foi de 8,98 unidades, a eficiência energética foi superior a 38, demonstrando alta sustentabilidade do sistema agrícola, tendo atingido energia cultural superior a 37 mil MJ ha-1.

It is felt that there is the need to study the role of working capital management policies on profitability of a company. Conventionally, it has been seen that if a company desires to take a greater risk for bigger profits and losses, it reduces the size of its working capital in relation to its sales. If it is interested in improving its liquidity, it increases the level of its working capital. However, this policy is likely to result in a reduction of the sales volume, therefore of profitability. Hence, a company should strike a balance between liquidity and profitability. In this paper an effort has been made to make an empirical study of Indian Consumer Electronics Industry for assessing the impact of working capital policies & practices on profitability during the period 1994–95 to 2004–05. The impact of working capital policies on profitability has been examined by computing coefficient of correlation and regression analysis between profitability ratio and some key working capital policy indicator ratios.
