Background: Anterior cruciate ligament(ACL) injuries commonly occur during the early phase of landing and cutting tasks that involve sudden decelerations. The purpose of this study was to investigate the effects of jump height and jump speed on lower extremity biomechanics during a stop-jump task and the effect of cutting speed on lower extremity biomechanics during a side-cutting ***: Thirty-six recreational athletes performed a stop-jump task under 3 conditions: jumping fast, jumping for maximum height, and jumping for 60% of maximum height. Participants also performed a side-cutting task under 2 conditions: cutting at maximum speed and cutting at 60% of maximum speed. Three-dimensional kinematic and kinetic data were ***:The jumping fast condition resulted in increased peak posterior ground reaction force(PPGRF), knee extension moment at PPGRF,and knee joint stiffness and decreased knee flexion angle compared with the jumping for maximum height condition. The jumping for 60% of maximum height condition resulted in decreased knee flexion angle compared with the jumping for maxrimum height condition. Participants demonstrated greater PPGRF, knee extension moment at PPGRF, knee valgus angle and varus moment at PPGRF, knee joint stiffness, and knee flexion angle during the cutting at maximum speed condition compared with the cutting at 60% maximum speed ***: Performing jump landing at an increased jump speed resulted in lower extremity movement patterns that have been previously associated with an increase in ACL loading. Cutting speed also affected lower extremity biomechanics. Jump speed and cutting speed need to be considered when designing AC.L injury risk screening and injury prevention programs.

This work was devoted to the study of the physico-chemical properties of two clay minerals from the mountain District (West Côte d'Ivoire) referenced mE1 and mE2. These samples were characterized by the experimental techniques, such as X-ray diffraction (XRD), Infrared spectroscopy (IR), Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES), Differential Thermal Analysis and Thermogravimetry (DTA-TG), Brunauer, Emett and Teller method (BET), laser particle size analysis and Scanning Electron microscope (SEm). The main results of these analyses reveal that the two clay samples mainly contain quartz (52.91% for mE1 and 51.72% for mE2), kaolinite (36.60% for mE1 and 41.6% for mE2) and associated phases, namely goethite and hematite (13.47% for mE1 and 11.00% for mE2). The specific surface values obtained for samples mE1 and mE2 are 34.78 m2/g and 29.18 m2/g respectively. The results obtained show that the samples studied belong to the kaolinite family. After calcination, they could have good pozzolanic activity and therefore be used in the manufacture of low-carbon cements.

自信就等于能力吗？不完全是。在一个能让你更好认识自己的演讲中，实验心理学家罗宾·克雷默深入研究了邓宁-克鲁格效应（Dunning-Kruger effect），该效应认为那些能力最差的人往往最高估自己的技能。I don’t mean to brag, but there are lots of things that I’m pretty average at. From playing table tennis, cooking risotto, finding countries on a map, just to name a few. Now, in our everyday lives, we’re not typically assessed on our skills and abilities, so we’re forced to rely on our own judgments.

Cu-TDPAT(H_(6)TDPAT=2,4,6-tris(3,5-dicarboxylphenylamino)-1,3,5-triazine),a stable nanoporous metal-organic framework with rht topology,has sparked broad interest as an adsorbent for several chemical separation *** this work,in situ synchrotron diffraction experiments followed by sequential LeBail refinements reveal that Cu-TDPAT shows unusually large anisotropic negative thermal expansion(NTE).The PASCal crystallography tool,used to analyze the magnitude of the NTE,reveals an average volumetric thermal expansion coefficientαv=-20.3 mK^(-1).This value is significantly higher than the one reported for Cu-BTC(also known as HKUST-1),which contains the same Cu-paddlewheel building unit,αv=-12 mK^(-1).In situ synchrotron single crystal X-ray diffraction and in situ diffuse reflectance infrared Fourier transform spectroscopy(DRIFTS)were employed to shed light on the NTE *** these two methods,we were able to elucidate the three main structural motions that are responsible for the NTE *** more pronounced NTE behavior of Cu-TDPAT is attributed to the lower symmetry combined with the more complex ligand structure when compared to *** knowledge obtained in this work is important for understanding the behavior of the adsorbent under transient variable temperature conditions in fixed adsorption beds.

New Breakdown Electric Field Calculation for SF6 High Voltage Circuit Breaker Applications

引用

Plasma Science and Technology 2007年第6期9卷 690-694页

作者： Ph.robin-JOUAN m.YOUSFI AREVA T & D High Voltage Switchgear Research Centre 130 rue L.BLUM 69611 VilleurbanneFrance University of Toulouse LAPLACE-UMR 5213 CNRSUPS118 Route de Narbonne31062 Toulouse Cedex 9France

The critical electric fields of hot SF6 are calculated including both electron and ion kinetics in wide ranges of temperature and pressure, namely from 300 K up to 4000 K and 2 atmospheres up to 32 atmospheres respectively. Based on solving a multi-term electron Boltz- mann equation the calculations use improved electron-gas collision cross sections for twelve SF6 dissociation products with a particular emphasis on the electron-vibrating molecule interactions. The ion kinetics is also considered and its role on the critical field becomes non negligible as the temperature is above 2000 K. These critical fields are then used in hydrodynamics simulations which correctly predict the circuit breaker behaviours observed in the case of breaking tests.
