MAGNETOHYDRODYNAMIC SIMULATIONS OF RECONNECTION AND PARTICLE ACCELERATION: THREE-DIMENSIONAL EFFECTS
(IOP PUBLISHING LTD, 2011)
Magnetic fields can change their topology through a process known as magnetic reconnection. This process in not only important for understanding the origin and evolution of the large-scale magnetic field, but is seen as a ...
Testes de vigor para avaliação da qualidade fisiológica de sementesde Sebastiania commersoniana (Baill.) Smith & Downs.
The objective of this work was to evaluate the efficiency of different vigor tests to assess S. commersoniana seeds physiological quality during storage. Therefore, seeds were stored in cloth bags, plastic bags and glass ...
Outflow and plasma acceleration in Titan's induced magnetotail: Evidence of magnetic tension forces
(American Geophysical Union, 2014-12)
Cassini plasma wave and particle observations are combined with magnetometer measurements to study Titan´s induced magnetic tail. In this study, we report and analyze the plasma acceleration in Titan´s induced magnetotail ...
Evaluation of stress cracking on geomembranes after accelerated tests
This paper presents results of stress cracking tests performed in high density polyethylene (HDPE) geomembranes (GM). Stress cracking tests were performed in accordance to ASTM D5397: Notched Constant Tensile Load Test ...
TENSILE AND CREEP BEHAVIOR OF GEOSYNTHETICS USING CONFINED-ACCELERATED TESTS
(IOS Press, 2013-01-01)
A major aspect in geosynthetics creep analysis is the load level applied to the specimen, usually referred as a percentage of the geosynthetic ultimate tensile strength (UTS). Since both tensile and creep standard tests ...
