Cold formed steel-framed constructions have been strongly disseminated with particular emphasis on the residential sector due to their fast execution, quality control and final cost. However, this construction typology presents a weakness associated with a low thermal inertia and a consequential risk of overheating. The present research addresses the overheating rate reduction of a cold formed ...

The paper presents the research on the infl uence of melt overheating temperature on crystallization parameters and primary structure of cast AlSi17Cu5Mg (A390.0) alloy overheated to temperature: 820 °C, 880 °C, 940 °C and 1 000 °C. It was found that the degree of overheating infl uences the change of microstructure signifi cantly and morphologies of primary silicon of the castings from Al-Si a...

Three hours after irradiation in a dose of 800 R rats proved to be less resistant to following overheating (45 degrees C) than control animals. An increase of resistance to acute overheating was revealed at the end of 3 days after the irradiation. At the height of the radiation disease (the end of the 5th day) the period of occurrence of heat stroke and the duration of rat survival failed to di...

Three-dimensional metallic microstructures find applications as stents in medicine, ultrabroadband antennas communications, micromechanical parts, or structures of more fundamental interest photonics like metamaterials. Direct metal printing such using three-dimensional (3D) laser lithography is a promising approach, which enables the fabrication 3D with sub-micron-sized features. Yet, this tec...

Processing in a magnetic field leads to the texturing of materials along an easy-magnetization axis when a minimum anisotropy energy exists at the processing temperature; the magnetic field can be applied to a particle assembly embedded into a liquid, or to a solid at a high diffusion temperature close to the melting temperature or between the liquidus and the solidus temperatures in a region o...

A pronounced effect of overheating is observed on the crystallization behavior for the three zirconium-based bulk metallic glasses: Zr41.2Ti13.8Cu12.5Ni10Be22.5 , Zr57Cu15.4Ni12.6Al10Nb5 , and Zr52.5Cu17.9Ni14.6Al10Ti5 . A threshold overheating temperature is found for each of the three alloys, above which there is a drastic increase in the undercooling level and the crystallization times. Time...

Previously we identified the receding flow, where two fluid streams recede from each other, as an open numerical problem,1 because all well-known numerical fluxes give an anomalous temperature rise, thus called the overheating problem. This phenomenon, although presented in several textbooks,2,3 and many previous publications, has scarcely been satisfactorily addressed and the root cause of the...

Climate heat waves occurring in urban centers are a serious threat to public health and wellbeing. Historically, most heat-related mortalities have arisen from excessive overheating of building interiors housing older occupants. This paper developed an approach that combines the results simulation bioheat models generate health-based limit criteria for long-term care homes (LTCHs) by which body...
