We present a study of the maximum stress supported by elastics bands of nitrile as a function of the natural length and the load time. The maximum tension of rupture and the corresponding variation in length were found by measuring the elongation of an elastic band when a mass is suspended from its free end until it reaches the breaking point. The work done by non-conservative forces was calcul...

This paper examines the effects of multicycles desorption/adsorption on water isotherms a typical cement–bentonite mixture. These were evaluated over relative humidity (RH) range 90% and 0.3%. study shows that, after first adsorption–desorption cycle, subsequent cycle shifted isotherm curves upward, particularly at RH < 70%, with high degree hysteresis. In contrast, > slightly downward lo...

A prosthetic foot is an important element of a prosthesis, although it is not always fully recognized that the properties of the foot, along with the prosthetic knee joint and the socket, are in part responsible for the stability and metabolic energy cost during walking. The stiffness and the hysteresis, which are the topics of this paper, are not properly prescribed, but could be adapted to im...

in this paper the optimal design of a dissipator made of aluminium and steel and principallysubjected to shear forces and the preliminary results of the characterization tests are described.the device has been designed on the basis of an optimization procedure with the objective tomaximize the energy dissipated in the device. the response of a 3d frame equipped with thedevice and subjected to 7...

Heteroleptic iron(III) complexes of formula [Fe(qsal-Cl)(thsa)] ̈nMeCN have been synthesized; [Fe(qsal-Cl)(thsa)] ̈MeCN, 1 and [Fe(qsal-Cl)(thsa)], 2. The latter can be obtained by slow evaporation of solutions of compound 1 under ambient conditions, a rare occurrence in nonporous compounds. 1 interestingly shows a unique magnetic profile over the de-solvation temperature range, 300-350 K, in the...

2014 Measurements of the hysteresis cycle of the magnetization of CuMn 1 % in the spin glass state as a function of the concentration of a non magnetic impurity show that the width of the hysteresis is proportional to the concentration of Au at a rate of 6.2 ± 0.4 kOe/at. % Au. A much smaller rate observed for Al and Ag and higher rate observed for Pt demonstrate unambiguously that the spin orb...

The magnetization of hollow superconducting filaments in a perpendicular applied field is calculated numerically using a mathematical model. With this model the hysteresis losses over a closed cycle of the applied field, as well as the instantaneous power dissipation in the filament, can be calculated. Theoretical results are compared with data from experiments using wire with hollow Nb3Sn fila...

Evapotranspiration (ET) is an important component of the water cycle in terrestrial ecosystems. Understanding the ways in which ET changes with meteorological factors is central to a better understanding of ecological and hydrological processes. In this study, we used eddy covariance measurements of ET from a typical alpine shrubland meadow ecosystem in China to investigate the hysteresis respo...
