1. Cost minimization analysis of an in-house molecular test for cytomegalovirus in relation to a commercial molecular system
ABSTRACT Introduction: Cytomegalovirus may cause severe disease in immunocompromised patients. Nowadays, quantitative polymerase chain reaction is the gold-standard for both diagnosis and monitoring of cytomegalovirus infection. Most of these assays use cytomegalovirus automated molecular kits which are expensive and therefore not an option for small labora

2. 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

3. NETWORK FLOW ORIENTED APPROACHES FOR VEHICLE SHARING RELOCATION PROBLEMS
ABSTRACT Managing a one-way vehicle sharing system means periodically moving free access vehicles from excess to deficit stations in order to avoid local shortages. We propose and study here several network flow oriented models and algorithms which deal with a static version of this problem while unifying preemption and non preemption as well as carrier ridi

4. Application of a Greedy Algorithm to Military Aircraft Fleet Retirements
ABSTRACT This article presents a retirement analysis model for aircraft fleets. By employing a greedy algorithm, the presented solution is capable of identifying individually weak assets in a fleet of aircraft with inhomogeneous historical utilization. The model forecasts future retirement scenarios employing user-defined decision periods, informed by a cost

5. A protocol for measuring spatial variables in soft-sediment tide pools
ABSTRACT We present a protocol for measuring spatial variables in large (>50 m2) soft-sediment tide pool. Secondarily, we present the fish capture efficiency of a sampling protocol that based on such spatial variables to calculate relative abundances. The area of the pool is estimated by summing areas of basic geometric forms; the depth, by taken representat

6. 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

7. 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,

9. 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

11. 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

12. New concept of space radiator with variable emittance
A new concept of space radiator of variable emittance for satellite thermal control is presented. The radiator is composed of two stages which exchange heat through radiation between finned surfaces covered with variable emittance coatings, whose emissivity is increased with temperature. Under cold conditions the radiative heat coupling between the stages is
