1. Regionalização de vazões de referência Q7,10 e Q90
The main objective of the research was the study and application of different methods for estimating ten years return period minimum annual seven consecutive days low flows (Q7,10) and minimum flows associated with remaining 90% in time (Q90), for the region between Doce and Itabapoana basins, through the hydrological regionalization. The three compared meth

2. Regionalização de vazões médias de longo período e de volumes de reservatórios de regularização
In this work, hydrological regionalization was utilized for estimating long-period average flow and reservoirs volumes in watersheds. For the regionalization of longperiod average flows, were analyzed three methods: Eletrobrás (1985a), linear interpolation, and Chaves et al. (2002). The acquisition of physical and climatic information, for regionalization,

3. Análise fluviológica e ambiental da bacia hidrográfica do rio Jaú - SP
The fluviological analysis is an important tool for planning and managing watersheds once that, by means of the characterization of discharges regime and the pulse of a water curse, it helps to indicate their hydrological state and the contributes to handle the natural resources with focus on ecosystemic services. Using secondary data and knowledge of statis

4. Procedimentos para aprimorar a regionalização de vazões: estudo de caso da bacia do Rio Grande / Procedures to improve the hydrologic regionalization: study of Rio Grandes basin
The hydrologic regionalization constitutes an efficient instrument to plan and manage the water resources, and it can be used to obtain the hydrological variables, as the maximum, minimum and medium discharges, in a simple and fast way. This technique can minimize the absence of hydrologic information in sites with low or no data availability. However, some

5. Proposta conceitual para a regionalização de vazões / Conceptual proposal for the hydrologic regionalization
The knowledge water availability through hydrographic net is fundamental to management water resources concession use rights. Normally this knowledge is restrict to the places where exist fluviométrica measurement station. Hydrologic regionalization is a technical tool to supply lack of information where there are few or no data availability. From a socio-

6. Management of water resources: integrated system for optimization of the water use granting / Gestão de recursos hídricos: sistema integrado para otimização da outorga de uso da água
O conhecimento da disponibilidade hídrica é a informação básica para a tomada de decisão no processo de outorga, sendo que a necessidade de conhecer a vazão ao longo da rede hidrográfica requer a utilização de técnicas de regionalização de vazões. A aplicação dos modelos de regionalização constitui, entretanto, uma dificuldade para a quanti

7. Statewide regionalization of pancreaticoduodenectomy and its effect on in-hospital mortality.
OBJECTIVE: This study examined a statewide trend in Maryland toward regionalization of pancreaticoduodenectomy over a 12-year period and its effect on statewide in-hospital mortality rates for this procedure. SUMMARY BACKGROUND DATA: Previous studies have demonstrated that the best outcomes are achieved in centers performing large numbers of pancreaticoduode

8. The effects of regionalization on cost and outcome for one general high-risk surgical procedure.
PURPOSE: The effects of regionalization of tertiary care were studied by analyzing cost and outcome for pancreaticoduodenectomies in a state in which the majority of these high-risk procedures were performed in one hospital. METHODS: Using Maryland inpatient discharge data via a retrospective study, the authors compared cost and outcome data for a hospital w

9. Trauma case mix and hospital payment: the potential for refining DRGs.
Uniform hospital discharge abstract data from Maryland were used to examine the homogeneity of trauma-related DRGs with respect to a well-established measure of injury severity, the Injury Severity Score (ISS). Thirty DRGs were identified as including trauma cases with a wide range of severity; for each of these DRGs, ISS explains a significant amount of var

10. A statewide, population-based time-series analysis of the outcome of ruptured abdominal aortic aneurysm.
OBJECTIVES: The purpose of this study was to perform the first statewide, population-based, time-series analysis of the frequency of ruptured abdominal aortic aneurysm (RAAA), to determine the outcomes of RAAA, and to assess the association of patient, physician, and hospital factors with survival after RAAA. The hypotheses of the study were as follows: 1) t
