1. STOCHASTIC DISCRETE LOT-SIZING WITH LEAD TIMES FOR FUEL SUPPLY OPTIMIZATION
ABSTRACT We address the problem of expected cost minimization of meeting the uncertain fuel demand during a time planning horizon, where supply is provided by selecting discrete shipments with lead times. Due to uncertainty and the passage of time, corrective actions can be taken such as cancellation and postponement on supply of shipments with associated co

2. Study and Assessment of the Efficiency of the Cocoa Bark Extracted from the Theobroma Cacao as an Inhibitor of the Corrosion of Carbon Steel in Substitution of Benzotriazole
Corrosion represents high losses to the economy, therefore, researches on the minimization of its damages in materials, mainly the metallic ones, are necessary. Among the various alternatives of protection against corrosion, there is the application of corrosion inhibitors that can minimize or even stop the corrosive process of metallic materials. However, a

4. Simulation of diets for dairy goats and growing doelings using nonlinear optimization procedures
ABSTRACT The objective of this study was to simulate total dry matter intake and cost of diets optimized by nonlinear programming to meet the nutritional requirements of dairy does and growing doelings. The mathematical model was programmed in a Microsoft Excel(r) spreadsheet. Increasing values of body mass and average daily weight gain for growing doelings

5. Health economics and health preference concepts to orthopedics practitioners
The aim of this study was to describe concepts of health economics in order to update and provide the orthopedic practitioner decision making parameters based on preferences. Four basic types of studies of economical evaluation were presented (cost minimization analysis, cost-benefit, cost-effectiveness and cost-utility), as well as the origin, the concept,

6. Utilization of minimum quantity lubrication (MQL) with water in CBN grinding of steel
The use of cutting fluids is fundamental to machining processes, mainly when it comes to high heat generation, which is the case of grinding. Thus, lubrication and cooling provided by cutting fluids improve the final quality of the workpiece. However, cutting fluid usage provide some drawbacks concerning environmental, costs and health issues. Therefore, new

7. Pharmacoeconomic analysis of clinical pharmacy in HIV-positive patients / Análise farmacoeconômica da farmácia clínica em pacientes HIV positivo = : Pharmacoeconomic analysis of clinical pharmacy in HIV-positive patients
Studies demonstrate that clinical pharmacy with HIV-positive patients can lead to positive clinical results. However, few studies evaluate its economic impact. The objective of this study is to verify the economic impact of pharmaceutical care with HIV-positive patients. A prospective controlled study with systematic sampling by quota with controls paired by

8. Despacho online para o problema dinâmico de roteamento de veículos
The allocation of vehicles for a specific customers demand is subject to a combinatorial explosion of possibilities by the exponential increase of alternatives according to growth of the problem size. When environmental changes are considered, such as the advent of new customers, the Vehicle Routing Problem becomes dynamic and even more complex and unpredict

9. Aumento da resposta analítica por meio da otimização do sistema de injeção sem divisão de fluxo em cromatografia gasosa empregando a lei dos gases ideais
This paper reports the development of an easy, fast and effective procedure for the verification of the ideal gas law in splitless injection systems in order to improve the response. Results of a group of pesticides were used to demonstrate the suitability of the approach. The procedure helps establish experimental parameters through theoretical aspects. The

10. Minimização do custo de produção como critério na formulação de dietas para bovinos de corte.
RESUMO: O critério de minimização do custo de matéria seca (MCMS) é frequentemente adotado para a formulação de dietas para animais. Esse critério, entretanto, possui limitações para bovinos, pois a solução aplica-se apenas a um nível de desempenho animal esperado, enquanto na prática, existem vários níveis de desempenho possíveis de serem i

11. MODELO HIDRÁULICO BASEADO NO MÉTODO DAS CARACTERÍSTICAS E ALGORITMOS GENÉTICOS PARA OTIMIZAÇÃO DA OPERAÇÃO DE REDES DE ABASTECIMENTO DE ÁGUA E DE ESTAÇÕES DE BOMBEAMENTO
A hydraulic model was developed for simulation of water supply networks using the Method of Characteristics (MOC), introducing new features to the CALHIDREDMT model, proposed by Righetto (1994). The model uses the concept of pseudo-transient, using a fictitious value for the wave celerity. Simulations were performed in networks equipped with reservoirs, tank

12. Benefícios sociais e ambientais do coprocessamento de pneus inservíveis: estudo de caso na cidade de João Pessoa-PB
The useless tire is a residue that must be managed correctly until its final disposal as well as its collection and storage must be done adequately. Therefore, if it is inadequately disposed of, it can cause damages to the environment and to public health. In March 2005 the city of João Pessoa, initiated a program called Programa Nordeste Rodando Limpo - No
