5. Interspecific Competition Between Sweet Sorghum and Weeds
RESUMO: Enquanto evidências indicam o sorgo sacarino [Sorghum bicolor (L.) Moench] como uma matéria-prima de etanol alternativa durante a entressafra da cana-de-açúcar (Saccharum officinarum L.), pouco se sabe sobre sua capacidade produtiva em condições adversas (sob competição com plantas daninhas, por exemplo). Portanto, o objetivo do presente estu

7. Behavior of buffalo heifers reared in shaded and unshaded pastures during the dry season on Marajó Island, Pará, Brazil
ABSTRACT. The objective of this research was to evaluate the behavior of twenty buffalo heifers reared during the dry season on Marajó Island, Pará, Brazil. The animals were distributed into two groups, those with shade (WS) and those without shade (WOS). The experimental day was divided into six shifts: morning (6:00 to 9:55 a.m.), intermediate (10:00 a.m

8. Use of Kisser glycerol gelatin to prepare microscope slides of Phlebotomine sandflies (Diptera: Psychodidae)
Abstract INTRODUCTION: Appropriate preservation of specimens is important for taxonomic identification. In sandfly research, various methods have been used for slide preparation; however, high cost, low commercial availability, and associated hazards make their use impossible in some studies. Therefore, the efficacy of Kisser glycerol gelatin for sandfly s

9. Releasing systems for aerospace industry based upon Shape Memory Alloys: characterization of materials for actuators
ABSTRACT Releasing and deployment maneuvers carried out during space satellites launching are usually performed by utilizing pyrotechnics loads. However, it is considered convenient to replace this technique by others not requiring explosives (Non Explosive Actuators-NEA). This is mainly due to the necessity of reducing high-shock and vibrations induced leve

11. Brazil’s Discourse on the Environment in the International Arena, 1972-1992
Abstract In this article, I analyse key statements by the Brazilian government about environmental issues during two important decades, from 1972 to 1992. I identify the specific subjects addressed by Brazilian spokespersons, and the rhetorical strategies they adopted for doing so. I conclude that these spokespersons largely adopted a defensive posture in re

12. Experimental Investigation of Ionization Sensors under Shock Tube Stagnation Conditions
ABSTRACT: Recently, there has been a growing interest in studies concerning ionization sensors for aerospace applications, power generation, and fundamental research. In aerospace research, they have been used for studies of shock and detonation waves. Two key features of these sensors are their short response time, of the order of microseconds, and the fact
