Effect of different surface oxidation treatments on structural, mechanical and tribological properties of ultrafine-grained titanium
(Elsevier Science Sa, 2014)
Four different surface oxidation treatments, so-called, anodizing oxidation (AO), micro-arc oxidation (MAO), plasma oxidation (PO) and thermal oxidation (TO), were applied to ultrafine-grained (UFG) pure titanium produced ...
The use of cation packing index for characterizing the weathering degree of granitic rocks
(Elsevier, 2008)
The weathering state and weatherability of rocks are highly important for engineering geology projects and the use of rocks as building stones. The weathering state of rocks can be described by various chemical and ...
Primary Growth Parameters of Three Alfalfa Cultivars Adapted to Highland Climatic Conditions
(Wiley-Blackwell, 2015)

Series tuned mass dampers in vibration control of continuous railway bridges
(Techno-Press, 2020)
This paper presents the applicability of series tuned mass dampers (STMDs) to reduce the multiple resonant responses of continuous railway bridges under high-speed train. The bridge is modeled by two-span Bernoulli-Euler ...
Production and Characterization of Bacterial Cellulose from Citrus Peels
(Springer, 2019)
Cellulose is the most common polymer in the world, formed by beta-1,4 linked glucopyranose units. In this study, citrus peels (lemon, mandarin, orange and grapefruit) were used for the production of bacterial cellulose ...
