Properties of compacted copper fibre reinforced cement composite
(1985)
This paper presents the properties of a new fibre cement material formed by short ductile copper fibres randomly distributed in portland cement paste and compacted by compression to 35 MPa. The optimum percentage and the ...
Effect of sedimentary and metamorphic aggregate on static modulus of elasticity of high-strength concrete
(Universidad Nacional de Colombia Sede Medellín, 2011)
Taking into account the increasing use of high-strength concrete as a structural material in Colombia, this paper shows the results of research carried out to investigate the effect of different types of coarse aggregate ...
Electromyographic and Safety Comparisons of Common Lower Limb Rehabilitation Exercises for People With Hemophilia
(Oxford University Press, 2020)
Background. Ankles and knees are commonly affected in people with hemophilia and
thus are targets for prevention or rehabilitation. However, to our knowledge, no studies
have evaluated muscle activity and safety during ...
Strength of polycrystalline coarse-grained platinum to 330 GPa and of nanocrystalline platinum to 70 GPa from high-pressure x-ray diffraction data
(AMER INST PHYSICS, 2008-03-15)
X-ray diffraction patterns from platinum foil 300 nm grain size have been recorded up to
330 GPa using a beveled-anvil diamond cell. The compressive strength has been determined from
the analysis of the diffraction ...
A spectral approach for nonlinear transversely isotropic elastic bodies, for a new class of constitutive equation: Applications to rock mechanics
(Springer, 2020)
A constitutive equation is provided for nonlinear transversely isotropic elastic solids, wherein the linearized strain tensor is assumed to be a function of the Cauchy stress tensor; this elastic constitutive equation ...
EMG, Rate of Perceived Exertion, Pain, Tolerability and Possible Adverse Effects of a Knee Extensor Exercise with Progressive Elastic Resistance in Patients with Severe Haemophilia
(MDPI, 2020)
In people with haemophilia (PWH), elastic band training is considered an optimal option, even though the literature is scarce. The aim was to evaluate normalized electromyographic amplitude (nEMG), rate of perceived exertion ...
Safety and effectiveness of progressive moderate-to-vigorous intensity elastic resistance training on physical function and pain in people with hemophilia
(Oxford Univ Press Inc, 2020)
Objective. Strength training is recommended for people with hemophilia; however,
published data are anecdotal and have methodological limitations. The purpose of this
study was to evaluate the safety and effectiveness ...
Implementation of the ultrasonic through-transmission technique for the elastic characterization of fiber-reinforced laminated composite
(Universidad Nacional de Colombia. Sede Medellín. Facultad de Minas, 2019)
Los compuestos laminados son usados en aplicaciones donde una alta relación resistencia/peso es requerida. Las industrias aeronáutica, naval y automotriz usan estos materiales para reducir el peso de sus vehículos y ahorrar ...
Inalambric biofeedback devices to analyze strength manifestation in military population
(Journal of Medical Systems, 2018)
