14. The Use of an Atmospheric Model to Simulate the Rocket Exhaust Effluents Transport and Dispersion for the Centro de Lançamento de Alcântara
ABSTRACT: This paper introduces a new approach to represent the rocket exhaust effluents into an atmospheric dispersion model considering the trajectory and variable burning rates of a Satellite Vehicle Launcher, taking into account the buoyancy of the exhausted gases. It presents a simulation for a Satellite Vehicle Launcher flight at 12:00Z in a typical da

15. Suicide and meteorological factors in São Paulo, Brazil, 1996-2011: a time series analysis
Objective: Considering the scarcity of reports from intertropical latitudes and the Southern Hemisphere, we aimed to examine the association between meteorological factors and suicide in São Paulo. Method: Weekly suicide records stratified by sex were gathered. Weekly averages for minimum, mean, and maximum temperature (°C), insolation (hours), irradiati

16. A model for implementation of HACCP system for prevention and control of mycotoxins during the production of red dried chili pepper
Abstract Hazard analysis and critical control points (HACCP) is a process control system describes the potential hazards during food production flow chart. In contrast to the conventional way of ensuring product safety by end-product testing, HACCP establishes control systems, focuses mainly on preventive measures. Quality of red dried chili pepper (RDCP) sh

17. Is It Possible to Classify Topsoil Texture Using a Sensor Located 800 km Away from the Surface?
ABSTRACT It is often difficult for pedologists to “see” topsoils indicating differences in properties such as soil particle size. Satellite images are important for obtaining quick information for large areas. However, mapping extensive areas of bare soil using a single image is difficult since most areas are usually covered by vegetation. Thus, the aim

18. Association between NOx exposure and deaths caused by respiratory diseases in a medium-sized Brazilian city
Exposure to nitrogen oxides (NOx) emitted by burning fossil fuels has been associated with respiratory diseases. We aimed to estimate the effects of NOx exposure on mortality owing to respiratory diseases in residents of Taubaté, São Paulo, Brazil, of all ages and both sexes. This time-series ecological study from August 1, 2011 to July 31, 2012 used infor

19. An Analytic Model for Dispersion of Rocket Exhaust Clouds: Specifications and Analysis in Different Atmospheric Stability Conditions
ABSTRACT: This paper brings the first results concerning a new analytic model to evaluate atmospheric dispersion in rocket launch scenarios, namely Generalized Integral Laplace Transform Technique for Rocket effluent dispersion model. The model is constituted by three different modules, being two pre-processors (micrometeorological parameters and deposition

20. DENSITY, REFRACTIVE INDEX, APPARENT VOLUMES AND EXCESS MOLAR VOLUMES OF FOUR PROTIC IONIC LIQUIDS + WATER AT T=298.15 AND 323.15 K
Abstract Densities and refractive index of binay mixtures of water with four protic ionic liquids, based on ammonium and fatty acids, were measured at 298.15 and 323.15 K, under atmospheric pressure. Apparent and excess molar volumes were obtained by experiments and fitting data to the Redlich-Meyer (RM), Redlich-Kister (RK) and Prigogine-Flory-Patterson (PF

21. The Sensitivity of Wind Forecasts with a Mesoscale Meteorological Model at the Centro de Lançamento de Alcântara
ABSTRACT: The sensitivity of the planetary boundary layer (PBL) parameterizations is investigated using the hybrid Fifth Generation Penn State University/National Center for Atmospheric Research (NCAR) Mesoscale Model (MM5) and its results were compared with observations from two field campaigns held during the dry and wet seasons at the Centro de Lançament

22. Impacto de um mecanismo de disparo da convecção na precipitação simulada com o modelo regional BRAMS sobre a bacia amazônica durante a estação chuvosa de 1999
O objetivo deste artigo é mostrar o impacto da implementação de uma função de disparo da convecção na parametrização convectiva de Grell e Devenyi, contida no modelo atmosférico regional BRAMS (Brazilian developments on Regional Atmospheric Model). Para verificar o ciclo de precipitação foi usado um conjunto de dados do período chuvoso de 1999 n

23. RELAÇÃO ENTRE A TEMPERATURA DA SUPERFÍCIE DO MAR E A CAMADA DE MISTURA OCEÂNICA SOB A PASSAGEM DE CICLONES EXTRATROPICAIS NO ATLÂNTICO SUDOESTE
Neste artigo investigou-se a importância da variação da camada de mistura oceânica (CMO) na temperatura da superfície do mar (TSM), sob a influencia de ciclones extratropicais atmosféricos. Um modelo simplificado de CMO oriundo do modelo HYCOM (Hybrid Coordinate Ocean Model), baseado no modelo de Kraus e Turner, foi inserido como uma sub-rotina do mode

24. Evento extremo de chuva-vazão na bacia hidrográfica do rio Araguari, Amapá, Brasil
O objetivo da investigação foi analisar vazões extremas ocorridas entre 9 e 14 de abril de 2011 na bacia do Rio Araguari-AP. A metodologia consistiu de três etapas principais: 1) re-análise da precipitação estimada pelo Modelo BRAMS (Brazilian in Development Regional Atmospheric Model System),utilizando como suporte a sinótica do mesmo período; 2) a
