the influence of ultrafine filler materials on mechanical and durability characteristics of concrete
this paper aims at investigating the influence of partial replacement of portland cement with ultrafine fillers compared to limestone powder on the durability and mechanical characteristics of concrete. for this purpose, ultrafine calcium carbonate materials with different specific surface areas of 9.7 and 15.1 m2/g and limestone powder (0.72 m2/g) were used. the results indicate that the ultra...
regionalism is an analytical and critical perspective which focuses on preserving special features of place and attempts to fill the vacuum in architecture. globalization is a complex multi-stage process that causes increasing complexity of time and place, greater awareness across the global and acceleration of cross cultural interactions. therefore, the present paper attempts to analyze global...

BACKGROUND It is unclear whether there is a clinical benefit to adding hydroxyapatite (HA) coatings to total knee implants, especially with the tibial component, where failure of the implant more often occurs. A systematic review of the literature was undertaken to identify all prospective randomized trials for determining whether the overall clinical results (as a function of durability, funct...
Thermal modification has been developed for an industrial method to increase the biological durability and dimensional stability of wood. In this study the effects of thermal modification on resistance against softand brown-rot fungi of sapwood and heartwood of Scots pine and Norway spruce were investigated using laboratory test methods. Natural durability against soft-rot microfungi was determ...
BACKGROUND Treatment of congenital heart disease may include placement of a right ventricle to pulmonary artery conduit that requires future surgical replacement. We sought to identify surgeon-modifiable factors associated with durability (defined as freedom from surgical replacement or explantation) of the initial conduit in children less than 2 years of age at initial insertion. METHODS Sin...
We have developed highly reliable and radiation-hardened power MOSFETs for use in outer space applications in satellites and space stations. The largest difference between these newly developed Rad-Hard Power MOSFETs and general-use MOSFETs is that they have excellent durability against high energy charged particles and ionizing radiation. To provide increased durability, electrical characteris...
the historian-theoretician christian norberg-schulz, examining the development of his ideas across 30 years. while norberg-schulz started out with intentions in architecture (1963), a work that was clearly influenced by structuralist studies, he soon shifted to a phenomenological approach with existence, space and architecture (1971), and then with genius loci (1980) and the concept of dwelling...
