In this study, first, different mix design of four types of Self-Compacting Concrete (SCC), 1. SCC consisted of only nanosilica, 2. SCC included only microsilica, 3. SCC consisted of both microsilica and nanosilica and 4. SCC without microsilica and nanosilica called as control mix, were casted and tested to find out the values of the Slump Flow, L-Box and 7 and 28 days compressive strength. Th...
Understanding of the geological characteristics of artificial stone is of particular importance. Appearance, size and dimensions, specification of particle surface and minerals forming aggregates are among the characteristics of rock materials that affect the homogeneous and cladding environment. Volume variations, water absorption, resistance to atmospheric agents and wear resistance are the m...
In this research, the efficiency of Recycled Glass Powder (RGP) is evaluated for improvement of polymer-modified bitumen and asphalt mixture performance. An extensive laboratory programm was undertaken for polymer-modified bitumen including Crumb Rubber (CR), Styrene Butadiene Styrene (SBS) and Styrene Butadiene Rubber (SBR). Rheological and mechanical proper...
Background and aim: Due to the composite structure of the jaw bone, gelatin and beta-calcium phosphate (b-TCP) biomaterials have been used repeatedly in bone tissue engineering. Despite the desirable properties of scaffolds made, their application has been limited due to their poor mechanical properties and high degradability. The aim of this study was to investigate the effect of clinoptilolit...
Objectives: In this article, a new procedure for increasing the light penetration depth in a tissue is studied and simulated. It has been reported that the most important problem in biomedical optical imaging relates to the light penetration depth, and so this makes a dramatic restriction on its applications. In the optical imaging method, the detection of the backscattered pho...
Genetic engineering innovations are protectable in intellectual property law system as intellectual properties. Protection of many of these innovations in economic, environmental, moral and human rights fundamentals is justifiable. Based on existing fundamentals in field of mentioned aspects, protection of genetic engineering innovations is provided to application of economic, environmental, mo...
Nanoclays are new generation of processed clays of interest in a wide range of high performance composites. In other words, nanoclay is defined as a clay that can be modified to make the clay complexes compatible with organic monomers and polymers. Here, it can be said that the polymeric nanocomposites are among the most exciting and promising classes of materials discovered recently. A number ...
Crystal engineering has recently emerged as a method of choice for the design and construction of organic as well as metal-organic functional materials. Crystal engineering attempts to establish packing trends in whole families of compounds and seeks to establish connections between structure and function. The utility of crystal engineering has also been expanded to the nanoscience and the deve...
due to medical and dietary properties of the plantago major l. seed, it is necessary to know engineering properties in order to design post harvest equipments. engineering properties of plantago major l. seed was determined only at the moisture content of 7.98% dry basis, because of it produces mucilaginous components when it is soaked in water. the average of length, width, surface area, spher...
