1. Experimental Investigation on the Evolution of Hydrogen in Steel during the Electroslag Remelting Process
Hydrogen, which is a harmful element, has a great effect on the mechanical properties of steel, should be removed during the steel manufacture process. The evolution of hydrogen content in steel during electroslag remelting process is experimentally investigated. The results show that during the electroslag remelting process, the hydrogen content in steel fi

2. Avaliação das Flutuacões Sazonais de Umidade e Sucção em um Perfil de Solo Tropical. / Predict of Suction and Humidity of Tropical Soils Using Mechanistic Model.
A avaliação da interação solo-atmosfera tem um papel fundamental em diversos exemplos de obras geotécnicas como operações de compactação, construção e operação de barragens e estabilidade de taludes. E geralmente, nestes exemplos, os solos se encontram no estado não saturado. Este trabalho tem como objetivo principal avaliar e aperfeiçoar a ab

3. Avaliando o Forecast Content dos Modelos Auto-regressivos Para arrecadaÃÃo de ICMS do Setor ElÃtrico do Estado do Cearà / Evaluating the Forecast Content of autoregressive models for collection of ICMS Power Sector in CearÃ
Neste ensaio investiga-se a perda de conteÃdo dos modelos de previsÃo autoregressivos, na medida em que se alarga o horizonte temporal no qual a variÃvel à estimada. O conteÃdo à medido pela reduÃÃo relativa do erro quadrado mÃdio que o modelo proporciona em comparaÃÃo ao processo simplificado de utilizar a mÃdia incondicional da sÃrie temporal.

5. FOREST FIRES IN MOUNTAIN NATIONAL PARK OF ITABAIANA - SERGIPE. / INCÊNDIOS FLORESTAIS NO PARQUE NACIONAL SERRA DE ITABAIANA SERGIPE.
This research was developed with the objective to determine the forest fire danger index that is the most efficient to predict forest fire inside the National Park Serra de Itabaiana. It also simulates the characteristics of the fire inside each type of vegetation, in order to characterize the risk in each situation. To simulate the forest fires, was used th

6. Precipitation forecast aided by weather radar for early warning system of urban floods / Previsão de chuva com auxílio de radar de tempo visando a um sistema de alerta antecipado de cheias em áreas urbanas
To reduce human and material losses during floods it is feasible to concisely study the rainfall forecast as the main part of an early warning system. The use of weather radar information, when linked to physically-based forecast models, can contribute for monitoring and forecasting of intense rainfall episodes. Thus, the rainfall forecast, based on using of

7. Calculation of the longevity of tomato seeds / Equacionamento da longevidade de sementes de tomate
The longevity is the period of time where the seeds are kept viable. Its extremely important for the storage analysis, the forecast of the viability loss of the seeds when comparing with differents storage conditions. The present work had as objective: to equate the initial quality of the seeds (Ki) of tomato in function of the initial tests of germination a

8. Modelo de predicción de riesgo de daño de la mosca pinta Aeneolamia postica (Walker) Fennah (Hemiptera: Cercopidae)
This paper evaluated the risk that Aenolamia postica (Walker) Fennah populations reach the economic threshold in sugar cane fields in Veracruz, México. A risk deductive model was constructed to include the sequence of events leading to damaging populations, considered the top event or critical failure in the crop. Model events were identified and quantified

9. Efeitos das condições de armazenagem sobre a qualidade da soja (Glycine max (L.) Merrill) e do óleo bruto / Effects of storage conditions on the quality of soybean grains (Glycine max (L.) Merrill) and crude oil
Brazil s 2005/06-grain production is forecast at approximately 123 million tons. Of this total, Brazil should produce 57 million tons of soybean grains, i.e., 46% of the national production. Brazilian agricultural production, however, needs to meet the international demands in order to gain foreign markets, maintaining good quality of grains is therefore ess

10. Energy and nutrients disposal in residences: the contrast between North and South Regions of Brazil / Disponibilidade de energia e nutrientes nos domicílios: o contraste entre Regiões Norte e Sul do Brasil
Food consumption is influenced by countless factors, among which can be emphasized the cultural, nutritional, socioeconomic and demografic ones. One acknowledges that, as these aspects benefit the adoption of new nutritional patterns, it will also be possible to distinguish the level of fulfillment of nutritional demands of the population. Information obtain

11. Uma metodologia para a avaliação dos gradientes de tenacidade a fratura ao longo da camada cementada do aço SAE 5115 / A model for fracture toughness evaluation of the carburized layer for SAE 5115 steel
The purpose of this work is to propose a model for evaluating the fracture toughness along the SAE 5115 steel carburized layer. Due to the small thickness of those layers, it is impossible to machine specimens from those layer in accordance with standards. For simulating the microstructures of the carburized layer in order to get samples for tensile and the
