This experimental study investigates the effect of steatite and fly ash on the fresh and hardened properties of self-compacting concrete (SCC).Accordingly, ordinary Portland cement (53 grade) was replaced with various fractions of fly ash (10% and 20%) and with various percentages (5%, 10%, 15%, 20%, and 25%) of steatite by weight of cement as a fi
Industrial progress is the source of social development.As one of the important links in the industrial production process, industrial particulate transportation systems such as coal, cement, mineral materials and food transportation cause jolly rancher filled gummies a large number of dust diffuse problems, which have become the pollution source o
Compartment fire is conducted by complex phenomena which have been the topics of many studies.During fire incident in a building, damage to occupants is not often due to the direct exposition to flames but to hot and toxic gases resulting from combustion between combustibles and surrounding air.Heat is therefore taken far from the source by combust
Aims: This in-vitro study aimed to compare the fatigue deformation of Polyetheretherketone (PEEK) and Cobalt-Chromium (Co-Cr) clasps by mechanical cycling test simulating ten years of use.Materials and Methods: 72 clasps samples were fabricated on a standardized e-max upper right first premolar; it is divided into 24 Co-Cr clasps, and 48 PEEK clasp
Outdoor-to-indoor (O2I) coverage in rubbermaid 8 gallon trash can urban areas by using the sub-6 GHz (sub-6G) band is important in the fifth generation (5G) mobile communication system.The spatial-temporal propagation characteristics in different polarizations in the 5G spectrum are crucial for the network coverage.In this paper, we measured the ur
