    Abstract: The friction forces between steel fiber and the concrete in the case of Straight Steel Fiber Reinforced Concrete (SSFRC) are considered as the main factor to generate the bonding between these two building construction materials. Three types of steel fiber are usually used in Fiber Reinforced Concrete (FRC) Straight, Dramix and Tabix. In the case o... Show More

    Abstract: Zinc oxide (ZnO) film was deposited on a porous silicon (PS) layer prepared by electrochemical etching through the thermal-evaporation method. ZnO nanocombs structure arrays were directly fabricated on the PS substrate through zinc powder evaporation, which uses a simple thermal-evaporation method without a catalyst. The ZnO nanocombs were highly o... Show More

    Abstract: Two types of composite cylindrical high-pressure vessels load-carrying capacity design procedure based on the discrete - structural theory are considered in this paper. The new design of the combined cylindrical vessel is offered. The cylinder includes an internal bearing fiberglass shell and an external protective metal cover. The vacuity between ... Show More
