    Abstract: Exact solution of an unsteady flow of elastico-viscous fluid through a porous media in a tube of spherical cross section under constant pressure gradient has been obtained in this paper. Initially, the flow is generated by a constant pressure gradient. After attaining the steady state, the pressure gradient is suddenly withdrawn and the resulting f... Show More

    Abstract: The main objective of this work was the design and construction of a bio-based novel photovoltaic. For this purpose, two prototypes were designed and constructed. The first was an efficient extraction prototype of active pigments, and then the validation of the pureness of the extracted pigments took place by using the Ultra Violet Visible region (...

    Abstract: This paper presents experimental test on sliding collapse. An array of up to fifty three tests on dry masonry specimens has been performed. Each specimen is subjected only to self-weight and to a horizontal load, whose position is chosen from a predefined set of three different locations. For the rest of properties, all specimens are totally equal.... Show More
