1. Budbreak of pecan cultivars subject to artificial chill
ABSTRACT Chill is a limiting factor in commercial production of temperate fruit due to their dormancy mechanism. Thus, knowledge of chill requirements of cultivars is important to reach successful production. This study aimed at evaluating responses given by different pecan cultivars subject to artificial chill. Pecan branches were collected from twelve 9-ye

2. Estabilidad de la austenita retenida bajo condiciones de deformación en aceros multifásicos con bainita nanoestructurada
ABSTRACT A steel with nominal composition 0.25C, 1.9Si, 0.63Mn, 1.5Cr was manufactured using an induction furnace. The as-cast alloy was homogenized and the temperatures of austenite start (AC1) and finish (AC3) during heating were determined by dilatometric analyses. Two intercritical austenitization temperatures were selected, which were used to perform pa

3. Neurosensory analysis of tooth sensitivity during at-home dental bleaching: a randomized clinical trial
Abstract Objective The objective of this study was to evaluate dental sensitivity using visual analogue scale, a Computerized Visual Analogue Scale (CoVAS) and a neurosensory analyzer (TSA II) during at-home bleaching with 10% carbamide peroxide, with and without potassium oxalate. Materials and Methods Power Bleaching 10% containing potassium oxalate was

4. Do you know this syndrome? Hand-foot syndrome
ABSTRACT Hand-foot syndrome is a common cutaneous adverse effect associated with certain systemic chemotherapy drugs. It is characterized by erythema, edema, and burning sensation, especially over palmoplantar surfaces. We report the case of an elderly patient undergoing chemotherapy after a breast cancer surgery who developed symptoms two months after the s

5. Evolución de la cooperación europea en inteligencia
European cooperation on intelligence among European countries does not start as late as it sounds. The difficult relationship maintained within Europe during the cold war may not suggest the existence of a strong collaboration and information and intelligence exchange. This article describes the evolution of this cooperation.

6. FROM DEBATE TO LAW: STATUE OF LIMITATIONS AND FREEDOM OF ASSOCIATION IN THE MAKING OF THE BRAZILIAN 1988 CONSTITUTION / DO DEBATE À POSITIVAÇÃO: A PRESCRIÇÃO E A LIBERDADE SINDICAL NO PROCESSO CONSTITUINTE DE 1987/1988
In this thesis, we seek to investigate all decision-making process - suggestions, considerations and concessions - on the implementation of worker¿s social rights in the Federal Constitution, specifically with respect to the five-year limitation period provided for in Article XXIX of the. 7 and the union structure, as laid out in Article 8. The aim is thus

7. Estudo dos componentes auxiliares de partida a frio de motores movidos a Diesel / Study of auxiliary components of cold start in Diesel engines
Cold start in Diesel engines is a problem which has not yet been properly solved and becomes particularly critical with the current trend to reduce the emission levels at low temperatures and engine compression ratio addressed to fuel consumption decrease. Although it is clear that there are some key factors whose control leads to a proper cold start process

9. Efeitos dos sistemas de pastejo isolado, simultâneo e alternado de ovinos com bovinos sobre as características da forragem, desempenho, consumo e características de carcaça dos ovinos / Effect of isolated; simultaneous and alternated pasture of sheep and cattle on pasture quality; performance; intake and carcass traits of sheep
The aim of this study was to evaluate the effects of three types of rotational pasture: isolated (I); simultaneous (S); and alternated (A) with sheep and cattle on structural and chemical traits of grass, voluntary dry matter intake, animal performance and carcass traits of sheep. The experimental period lasted 99 days. A experimental area of Panicum maximum

10. Proposição de um método para avaliação do adicional de emissões veiculares em partida a frio
As emissões de poluentes atmosféricos decorrentes de veículos automotores representam um grave problema ambiental. O modo de operação do veículo influencia diretamente a quantidade de poluentes emitidos. Quando um veículo inicia sua operação com motor frio, efeito denominado de partida a frio, a quantidade de poluentes emitidos torna-se consideravel

11. Steam and nitrogen injection in improved heavy oil recovery / Injeção de vapor e nitrogenio na recuperação melhorada de oleo pesado
Thermal recovery methods, especially steam injection, are at the forefront of most onshore projects of heavy oil. The continuous injection and, recently, the steam assisted gravity drainage yield high recoveries. The ratio of the volume of steam injected per volume of produced oil is a decisive parameter in the success of steam flood projects. In the present
