1. TIME AVAILABLE FOR SPRAYING AND MECHANIZED SOWING IN THE NORTHEAST OF THE STATE OF MATO GROSSO DO SUL AND SOUTH OF GOIÁS
ABSTRACT The sizing of mechanized agricultural systems depends on the soil and climatic conditions, the crop and the work regime. The aim of this study was to determine the probabilities of time available during an agricultural year for mechanized spraying and sowing in the northeast region of the State of Mato Grosso do Sul and south of Goiás. The meteorol

2. Microclimate and soil moisture in a silvopastoral system in southeastern Brazil
In this study, the microclimate changes in silvopastoral systems are quantified at different time and spatial scales and compared with single-pasture systems. The study was conducted in a silvopastoral system in São Carlos, Brazil (22°01' South and 47°53' West). The silvopastoral system consisted of grass pastures [Urochloa (sin. Brachiaria) decumbens cv.

3. Utilização das equações de Navier Stokes com a parametrização convectiva BMJ para prognóstico de temperatura, umidade e vento sobre diferentes condições de estabilidade atmosférica utilizando o modelo regional ETA / USE OF THE NAVIER - STOKES BMJ WITH CONVECTIVE PARAMETERIZATION FOR FORCAST TEMPERATURE, MOISTURE AND WIND ON DIFFERENT CONDITIONS OF ATMOSPHERIC STABILITY USING ETA REGIONAL MODEL
Nesta pesquisa é feita uma abordagem sobre o impacto da parametrização convectiva de Bettes Miller Janjic (BMJ) na temperatura, umidade e vento prognosticados pelo modelo ETA. Há vários trabalhos na literatura que focalizam este tema, poucos direcionados, em particular, para o estado da Paraíba, mas nenhum deles usa a metodologia descrita neste. É sab

4. Manifestações patológicas em conjuntos habitacionais: a degradação da fachadas
Cases of deterioration in building facades in Recife and surroundings have been subject to the attention of technical construction in the state of Pernambuco. The presence of visual changes caused by pathological manifestations (fungi, cracks, stains, etc.) in these areas is a warning sign that their performance is in decline. The word pathology, originating

5. Impacto da assimilação de dados de precipitação no sistema RPSAS/CPTEC: um estudo de caso de complexo convectivo de mesoescala / Impact of precipitation assimilation in CPTEC s RPSAS system: a case study of mesoscale convective system
This work presents the results of a impact study of estimated precipitation data assimilation in RPSAS from CPTEC, during January 2003. In this study, the precipitation assimilation was performed during the generation of first guess by the regional Eta model using a methodology similar to nudging. From this first guess, the RPSAS system generates an analysis

6. Inter-relação paleossolos e sedimentos em lençois de areia eolica da Formação Marilia (noroeste da Bacia Bauru) / Iterrelation of palaeosols and sediment in the ancient Marilia Formation aeolian sand sheets (northwestern Bauru Basin)
The Marília Formation (Maastrichtian), outcropping in the northwestern portion of the Bauru Basin (Goiás and Mato Grosso do Sul brazilian states), is interpreted here as an ancient Aeolian sand sheet. The vertical succession, c.150 m thick, is made up of very fine to medium-grained sandstone and, it is characterised by cyclic interbedding of sediments and

7. ESTUDO DOS FLUXOS TURBULENTOS DE CALOR SENSÍVEL E LATENTE NO FUNDO DO VALE DO RIO DA PRATA
Three observational campaigns have been conducted in the region of Nova Roma do Sul, southern Brazil. In the last one of them, a micrometeorological tower was deployed above the river surface, at the bottom of the Prata river valley. The purpose was to characterize the exchange between the river surface and the atmosphere. The micrometeorological parameters

8. EMISSÃO DE GASES DE EFEITO ESTUFA EM SISTEMAS DE MANEJO EM SOLO DO PLANALTO MÉDIO DO RIO GRANDE DO SUL / SHORT-TERM GREENHOUSE GASES EMISSIONS IN SOIL MANAGEMENT SYSTEMS IN OXISOL OF SOUTHERN BRAZIL
Agriculture is directly linked to atmospheric concentration of greenhouse gases (GHG) through basic processes that occur in the soil-plant system. Agricultural soils can act as a source or sink of GHG depending on the management practices adopted. The objective of this research was to evaluate the GHG flux in different soil management systems. This project w

9. Fronts and frontogenesis during summer: geometrical and dynamical aspects and the influence over rainfall on the South American subtropics / Frentes e frontogênese no verão: aspectos geométricos, dinâmicos e impactos sobre as chuvas nos subtrópicos da América do Sul
Three different aspects related to summer precipitation over subtropical South America (SA) and the continental pattern of humidity transport in that season are studied. Firstly, a climatological point of view is adopted and it is shown that most of the humidity that enters SA through its northern coast, up to Par´a, comes from the tropical Northern Atlanti

10. Padrões sinóticos de circulação atmosférica associados ao jato em baixos níveis a leste da Cordilheira ds Andes, na América do Sul / Atmospheric circulation patterns associated with the south america low level jet at east of the Andes
The objective of this studywas toidentify the atmospheric patterns circulationassociated with the South American Low-level Jet (LLJ). The zonal (u) and meridional (v) wind, geopotential height (f), temperature (T), specific humidity (q) and other variables from National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR)

11. Aspectos sinóticos associados à ocorrência do jato em baixos níveis na América do Sul - reanálise NCEP/NCAR e simulação com o MCGA CPTEC/COLA / Synoptics aspects associated to the occurrence of the low levels jet in the south America - reanalyses of the NCEP/NCAR and simulation with the MCGA CPTEC/COLA
Cases of LLJ occurrence to the east of Andes were identified in NCEP/NCAR reanalyses data and in daily results of a climate simulation with the CPTEC/COLA AGCM, to identify the associated atmospheric patterns. weather forecasting of a case when there was occurrence of LLJ was also evaluated. Analysis performed in different seasons indicated similar synoptic

12. Balanço de energia e evapotranspiração de cafezal adensado em crescimento sob irrigação localizada. / Energy balance and evapotranspiration in a high density young coffee under located irrigation.
The objectives of this study were to evaluate the magnitude of global evapotranspiration (ETc) in a high density young coffee crop (3.5mx0.9m) under drip irrigation, the ETc partition considering hedgerows and interrows, and the partition of the available radiant energy between sensible and latent heat fluxes. The experiments were conducted from September 20
