Base isolation systems are among the most successful and widely applied methods of mitigating structural vibration and damage during seismic events. These systems have been installed in numerous full-scale structures all around. There are three principal types of base isolators: Lead Rubber Bearing (LRB), High Damping Rubber Bearing (HDRB), and Fri...

Efficiency of trigonometric levelling method for height differences determination is better than those determined by geometric levelling but its accuracy is significantly lower. Development of accuracy of geodetic instruments increases possibilities for improvement accuracy of trigonometric levelling.However, air refraction appears as ultimate limi...

This study examined the impact of climate, altitude and landforms on humic acids (HA) optical properties (E4/E6, ∆logK, RF indexes) in Serbian Rendzina soils. HA humification degree of calcareous and decarbonated Rendzinas under natural vegetation (forest and grassland, separately) decreased with altitude increasing. This particular rule was not ma...

Total number of nineteen mafic extrusive rock samples is subjected to the detailed optical examination. Based on definition of mineral composition, structure, texture, type and intensity of alteration processes, and taking into consideration the recent classification schemes, different lithotypes are defined. The most frequent are spilites distingu...
