2. Energy balance partitioning and evapotranspiration from irrigated Muskmelon under Semi-Arid Conditions
ABSTRACT The Mossoró-Assu-Baraúna district, Rio Grande do Norte State (RN), is recognized by the intense production of horticulture, mainly muskmelon for export. However, this region is often devastated by intense droughts. Thus, the muskmelon production is predominantly under irrigated condition and, due to constant threat of water resources collapse on t

3. The role of bradykinin in lung ischemia-reperfusion injury in a rat lung transplantation model
ABSTRACT PURPOSE: To investigate the role of bradykinin in a rat lung transplantation (LTx) model and preliminarily discuss the relationship between bradykinin and CD26/DPP-4. METHODS: Rats were randomly divided into four groups: Control (CON), Sham, low potassium dextranglucose (LPD), and AB192 (n=15/group). Orthotopic single LTx was performed in the LPD

4. Energy balance and evapotranspiration of melon grown with plastic mulch in the Brazilian semiarid region
Melon plants (Cucumis melo L.) are grown in the state of Rio Grande do Norte (RN), the largest producer of melons in Brazil, with plastic mulch and agrotextiles. Studies of crop evapotranspiration (ET) under these conditions are required to ensure adequate irrigation. This study aimed to determine the crop coefficients (Kc) of irrigated melon plants grown wi

5. Surface energy exchange and evapotranspiration from cotton crop under full irrigation conditions in the Rio Grande do Norte State, Brazilian Semi-Arid
The main objectives of this study were documenting how energy balance partitioning and ET vary seasonally along each growth season of cotton crop under full irrigation conditions in the Brazilian semiarid. The studied area was located in the Apodi Plateau, which is located on west of Rio Grande do Norte state and is an area with extensive agricultural suitab

6. Full factorial design analysis of carbon nanotube polymer-cement composites
The work described in this paper is related to the effect of adding carbon nanotubes (CNT) on the mechanical properties of polymer-cement composites. A full factorial design has been performed on 160 samples to identify the contribution provided by the following factors: polymeric phase addition, CNT weight addition and water/cement ratio. The response param

8. MODELO DE ESTIMATIVA DA RADIAÇÃO LÍQUIDA E SUA APLICAÇÃO NA DETERMINAÇÃO DA EVAPOTRANSPIRAÇÃO POTENCIAL
This study aimed to assess and develop a physical mathematical model to estimats the net radiation. For this we used weather data collected from the meteorological station of the Department of Physics and Meteorology of the Escola Superior de Agricultura "Luis de Queiroz" - ESALQ - University of São Paulo - USP, Piracicaba, Brazil, according to the global r

10. Treatment of cutaneous tumors with topical 5% imiquimod cream
INTRODUCTION: There are various approaches to the treatment of cutaneous tumors; one of them is treatment with imiquimod, a synthetic toll-like receptor agonist with a low molecular weight that offers a topical, noninvasive, and non-surgical therapeutic option. The main objective of our study was to provide data on 89 patients who used a 5% imiquimod cream f

11. Water and energy fluxes in cowpea and castor beans cultivated in northeast Brazil / Fluxos de Ãgua e de energia em feijÃo macassar e mamona no nordeste do Brasil
The castor beans and cowpea are crops of enormous economic and social importance for the farmers in northeast Brazil, whereas the extracted oil of seeds of castor beans is used for production of biodiesel and the cowpea is the main food for poor population. Independent of crop type, the knowledge of water amount removed from soil by vegetation is of great in

12. An analysis of surface fluxes and of the microclimate on cerrado, sugarcane and eucalyptus: implications for regional climate changes / Uma análise dos fluxos de superfície e do microclima sobre cerrado, cana-de-açúcar e eucalipto, com implicações para mudanças climáticas regionais
This work investigates potential regional scale temperature and precipitation changes in the São Paulo state, caused by land use changes. We analised micrometeorological measurements, in the period February 2005 to February 2006, over three different ecosystems (cerrado, sugar cane and eucalyptus plantation). The surface energy balances showed that over the
