Abstract: the article provides a calculation justification of proposed railway structure on reinforced concrete sleeper-free base, for which an analysis existing methodology calculating track strength is carried out, according to dynamic loads acting from rolling stock are determined. The applied sleeper-less structures and results measurements emerging stresses in substructure, measured depth ...

The Chinese traditional architecture called as DaMu structure, which wooden materials were used mainly. The work of historic heritage conservation needs the surveying maps and the 3D model of the building. Laser scanning techniques can provide the best potential for high efficient and more safety recording of the 3D data. Recently, Terrestrial Laser Scanning (TLS) has been used in some architec...

The purpose of the research was to study condition prestressed monoblock concrete sleeper (PMCS) under dynamic loading experimentally and through site investigation. From this research, value deflection base on acceleration sleepers have been obtained. This showed possible correlation relation PCS located a railway track. includes experimentation process which experimental investigations for (P...

Wooden barrels are used in the ageing or maturation of many alcoholic beverages, namely brandies and wines. However, the high costs related to ageing in wooden barrels have led to a search for alternative technologies. In this study we examined the application of wood fragments to the beverage in order to promote an accelerated ageing. We evaluated the sensory and chemical modifications in bran...

The problem of damping the noise on track, arising from movement train, is solved sufficiently but it simple, if rail with spacers laid inside longitudinally located band sleeper-mechanism. result a layered thread, consisting belts: tape elastic three sides, tie-mechanism and ballast layer. unity layers carried out due to their own mass. This static track without external load. Rail compression...

Investigations of microbial diversity in Antarctic are important to begin to understand ecosystem functioning and decomposition processes. This study documents fungi at 9 historic sites on the Antarctic Peninsula collected from wooden structures, other organic materials, and soils during a joint National Science Foundation and British Antarctic Survey expedition in 2007. Many of these sites had...

OBJECTIVES To determine the off-shift sleep strategies of bi-ethnic night-shift nurses, the relationship between these sleep strategies and adaptation to shift work, and identify the participant-level characteristics associated with a given sleep strategy. METHODS African-American and non-Hispanic White female, night-shift nurses from an academic hospital were recruited to complete a survey o...

In Krylov's analytical prediction model, the free field vibration response during the passage of a train is written as the superposition of the effect of all sleeper forces, using Lamb's approximate solution for the Green's function of a halfspace. When this formulation is extended with the Green's functions of a layered soil, considerable computational effort is required if these Green's funct...
