1. The Role of Environmental Heterogeneity in the Seed Rain Pattern
ABSTRACT We focus on understanding the influence of environmental variables on ecological processes, and such a focus promotes an integrated view of forest ecological patterns. The following questions were made: Do variations in temperature, precipitation, litterfall deposition and light intensity influence the density and composition of seed rain in a stret

2. Predictive determinants of scorpion stings in a tropical zone of south Iran: use of mixed seasonal autoregressive moving average model
Abstract Background: More than 1.2 million scorpion stings occur annually worldwide, particularly in tropical regions. In the absence of proper medical care, mortality due to venomous scorpion stings is an important public health issue. The aim of the present study is to explore the temporal trend of scorpionism with time series models and determine the eff

3. Seasonal variation of haemoglobin A1c in a Portuguese adult population
Objective Haemoglobin A1c (Hb A1c) is routinely used for monitoring glycemic control in patients with diabetes. Hb A1c seasonal fluctuations can be directly related to different biological, geographical and cultural influences. Our purpose was to evaluate seasonal variation of Hb A1c in a hospital-based adult population over a period of 5 years.Materials and

4. BIAS DETECTION IN DEMAND FORECASTING / DETECÇÃO DE VIÉS NA PREVISÃO DE DEMANDA
The purpose of this dissertation is to propose two new methods for detection of biases in demand forecasting. These methods are adaptations of two statistical process control techniques, the EWMA control chart and the CUSUM control chart (or CUSUM algorithm), to the context of the detection of biases in demand forecasting. The performance of the proposed met

5. Nuevos aportes a la historia natural de la mulita pampeana Dasypus hybridus (Mammalia, Dasypodidae)
This contribution presents new data about the natural history of the Dasypus hybridus (Desmarest, 1804) (Mammalia, Xenarthra, Dasypodidae). A seasonal monitoring using the capture and release method was performed over the course of three years in a 100 ha of four cattle farms in the Buenos Aires province, Argentina. Data were collected on food habits, space

6. Enantiomeric distribution of key volatile components in Citrus essential oils
Citrus as many other plants present characteristic distribution of some enantiomers, thus it is often possible to use this parameter for identification, characterization, genuineness, and pharmacological activity assessment. In particular, it is possible to reveal adulteration of different nature, such as addition of synthetic compounds, or natural component

7. Os precos de bovinos no Pantanal Mato-Grossense.
The Pantanal of Mato Grosso is a plain of c. 139.000 km2, on the Brazilian central plateau, situated between 16o and 22o of latitude South and 55o and 58o longitude West, where one of the largest breeding center of beef cattle is developed. Animal husbandry is explored with minimal technical inputs within a climate of alternating water excess or sthortage. T

8. Variabilidade morfodinâmica das praias oceânicas entre Imbé e Arroio do Sal, RS, Brasil
The morphodynamic variability of the oceanic beaches between Imbé and Arroio do Sal towns, Rio Grande do Sul State, Brazil, was investigated by means of periodic beach profiling combined with the interpretation of granulometric and hydrodynamic regime data. A seasonal trend in the hydrodynamic regime, in the distribution of the sediments and in the morphome

9. Perfil espacial e temporal de poluentes nas águas da represa municipal de São José do Rio Preto, São Paulo, Brasil
In this manuscript, seasonal and spatial trends of water collected from two sampling places in the Preto River in the Turvo-Grande watershed were evaluated. Water samples were collected during June/07 to July/08 and parameters sulphate, total organic carbon, ammonia, conductivity, dissolved oxygen, temperature, dissolved total solids and nitrate were quantif

10. Adenovirus molecular detection and seasonal monitoring in bodies of water in the municipality of Goiânia, Goiás-Brazil: correlation with physical-chemical and bacteriological parameters and meta-analysis to evaluate methodologies / Detecção molecular e monitoramento sazonal de adenovírus em águas fluviais no município de Goiânia, Goiás-Brasil: correlação com parâmetros físico-químicos, bacteriológicos e Metanálise avaliativa de metodologias
Although water is of vital importance for living beings, due to antropic action it becomes a way of dissemination of several microorganisms, which reach aquatic environments through the faeces of man and other animals and can cause several illnesses, especially for immunocompromised individuals. During routine environmental monitoring, coliform bacteria are

11. OPTIMAL FILTERS THAT PRESERVE EVERY TREND ORDER / FILTROS ÓTIMOS QUE CONSERVAM QUALQUER ORDEM DE TENDÊNCIA
The thesis Filtros ótimos que conservam qualquer ordem de tendência (Optimal Filters that Preserve Trend of Any Order), investigates the principles of the Henderson symmetric filters, which are inserted in the context of seasonal adjustment, specifically in the methods of the X11 family; it also develops optimal filters, based on techniques in the Frequenc

12. Climate indices of temperature and precipitation over South America: present climate and validation of the RegCM3 model / Índices de extremos climáticos de temperatura e chuva na América do Sul: clima presente e validação do modelo RegCM3
The main goal of this study is to investigate if the RegCM3 model (Regional Climate Model version 3) is able to simulate the spatial patterns of some annual and seasonal climate indices of temperature and precipitation trend over South America for the present climate (1961-1990). The analysis is done for three different simulations where the model was runnin
