1. A Escola Francesa de Geografia
ABSTRACT It was evaluated the possibility to produce two seedlings per avocado seed, through the separation of cotyledons. Two seed lots from two different ungrafted trees were evaluated. From the first tree were obtained 60 seeds, and 50 from the second. Half the seeds of each lot had their cotyledons separated and then whole seeds and half-seeds were sown

2. Avocado: Is it possible to produce two seedlings with one seed?
ABSTRACT It was evaluated the possibility to produce two seedlings per avocado seed, through the separation of cotyledons. Two seed lots from two different ungrafted trees were evaluated. From the first tree were obtained 60 seeds, and 50 from the second. Half the seeds of each lot had their cotyledons separated and then whole seeds and half-seeds were sown

3. Performance and serum cortisol concentration in Santa Inês lambs under different suckling schemes
ABSTRACT The objective of this study was to examine the effects of suckling schemes (continued, controlled, and total separation) and the type of pregnancy on performance and serum cortisol concentration in lambs. A total of 29 Santa Inês ewes and 40 lambs were used, and the randomized block design was applied in a split-plot scheme with a 3 × 2 factorial

4. Efeito da descarga de barreira dielétrica no escoamento do ar sobre um cilindro / Effect of dielectric barrier discharge on the airflow around a cylinder
Fluids in a dielectric barrier DBD glow discharge at atmospheric pressure attracted the interest of the communities of thermo and fluid dynamics as well as control. This dissertation investigates the effects of a plasma actuator operating at 8 kV and 4.4 kHz, on the Cp curve of a PVC cylinder in a low velocity airflow. The experiment was repeated with the ac

5. Aircraft spacing for continuous descent approach in a terminal area based on required time of arrival at a metering fix.
Guiding arriving flights through congested terminal airspace has always been a challenge. As traffic builds up, controllers must often move traffic away from the airport until they can bring those flights in for landing, causing inefficiencies. A widespread implementation of Continuous Descent Approach (CDA) would result in significant reductions in environm

7. Recent developments in superstatistics
We provide an overview on superstatistical techniques applied to complex systems with time scale separation. Three examples of recent applications are dealt with in somewhat more detail: the statistics of small-scale velocity differences in Lagrangian turbulence experiments, train delay statistics on the British rail network, and survival statistics of cance

8. Numerical study of synthetic jet actuator effects in boundary layers
This work has as a fundamental objective the numerical study of the effects of synthetic jet actuators on the flow of the boundary layer developed on a flat plate and on a hypothetical airfoil. The aim is to obtain computational data to indicate how these effects may be used as a means of flow control, describing the dynamics of the synthetic jet in the pres

9. Study of the effects of a numerically simulated synthetic jet on the delay of separation of the boundary layer on a hipothetical airfoil / Estudo dos efeitos de um jato sintético simulado numericamente no atraso da separação de uma camada limite sobre um aerofólio hipotético
A realização deste trabalho tem como objetivo fundamental estudar os efeitos dos atuadores de jato sintético no escoamento de uma camada limite desenvolvida sobre uma placa plana e um aerofólio hipotético. A interação dos jatos sintéticos com um escoamento transversal pode conduzir a uma aparente modificação da forma aerodinâmica de corpos rombudo

10. Controle coerente em Ãtomos de Rb por manipulaÃÃo da fase de pulsos ultracurtos
Coherent quantum control aims to drive a quantum system towards a desired final state. Nowadays its study is widely employed to manipulate transitions in atomic systems, to break molecular bonds and to optimize the output of chemical reactions, for instance. In this thesis experimental and theoretical results of partial temporal coherent control in two diffe

11. Echo-delay resolution in sonar images of the big brown bat, Eptesicus fuscus
Echolocating big brown bats (Eptesicus fuscus) broadcast ultrasonic frequency-modulated (FM) biosonar sounds (20–100 kHz frequencies; 10–50 μs periods) and perceive target range from echo delay. Knowing the acuity for delay resolution is essential to understand how bats process echoes because they perceive target shape and texture from the delay separat

12. Centromere DNA mutations induce a mitotic delay in Saccharomyces cerevisiae.
Cytological observations of animal cell mitoses have shown that the onset of anaphase is delayed when chromosome attachment to the spindle is spontaneously retarded or experimentally interrupted. This report demonstrates that a centromere DNA (CEN) mutation carried on a single chromosome can induce a cell cycle delay observed as retarded mitosis in the yeast
