ANALYSIS OF CONTEMPORARY LIFE-STYLE ACCORDING TO GILLES LIPOVETSKY AND MICHEL MAFFESOLI: COMPARISON AND CONFRONTATION OF SELECTED THEMES, PROBLEMS AND CONTROVERSIES

The thesis analyzes and compares the approaches of two authors dealing with phenomena in contemporary society. It focuses mainly on issues of lifestyle and values. The thesis asks questions related to socialization and individualization of society. The thesis is divided into four parts. The first part is about definition of the basic terms (postmodernism, lifestyle, values). The second part is devoted to the concept of Gilles Lipovetsky. The third part focuses on the concept of Michel Maffesoli. In the fourth section, there is a comparison of these two concepts, where we are primarily focused on tracing argumentation clashes and controversies. In the final part, there is the presentation of the main questions and ideas, that come out on the basis of this comparison

A thin rectangular viscoelastic orthotropic plate under transverse impuls loading

An analytical solution of stress wave propagation in a thin rectangular viscoelastic plate with special orthotropy under transverse impulse loading is presented. The solution is based on the approximate theory of thin plates using the Kirchhoff and the Rayleigh corrections. Constitutive equations for two-dimensional linear viscoelastic Maxwell model of solid are derived using the superposition principle. Transverse impulse loading has been allowed to effect on an arbitrary point of the plate surface and it has general behaviour in time. Results in the form of displacement, velocities and stress components are obtained

Analytical and numerical investigation of trolleybus vertical dynamics on an artificial test track

Two virtual models of the ŠKODA 21 Tr low-floor trolleybus intended for the investigation of vertical dynamic properties during the simulation of driving on an uneven road surface are presented in the article. In order to solve analytically vertical vibrations, the trolleybus model formed by the system of four rigid bodies with seven degrees of freedom coupled by spring-damper elements is used. The influence of the asymmetry of a sprung mass, a linear viscous damping and a general kinematic excitation of wheels are incorporated in the model. The analytical approach to solving the ˇSKODA 21 Tr low-floor trolleybus model vibrations is a suitable complement of the model based on a numerical solution. Vertical vibrations are numerically solved on the trolleybus multibody model created in the alaska simulation tool. Both virtual trolleybus models are used for the simulations of driving on the track composed of vertical obstacles. Conclusion concerning the effects of the usage of the linear and the nonlinear spring-damper elements characteristics are also given

Hydrophobically Modified Celluloses as Novel Cholesterol-lowering Polymers

Hydrophobically modified celluloses were prepared by the esterification of monocarboxycellulose (MCC) and carboxymethylcellulose (CMC) with methanol, followed by the amino-de-alkoxylation of the methyl esters with n-octadecylamine. These cellulose derivatives were fed at 30 and 60 g/kg for 4 weeks to female rats. The diets were supplemented with palm fat (60 or 50 g/kg) and cholesterol (0 or 10 g/kg). There was no significant effect of amidated celluloses on the feed intake or body weight of rats. Both MCC and CMC derivatives significantly decreased the concentrations of cholesterol present in the serum and liver. The supplementation of diets with hydrophobically modified celluloses tended to increase fecal concentrations of cholesterol and coprostanol and significantly increased fecal concentrations of total neutral sterols. In rats fed diets containing cholesterol, the total serum cholesterol correlated negatively with the fecal concentrations of neutral sterols. It can be concluded that MCC-C18 and CMC-C18 are effective cholesterol-lowering agents
