One of the most dangerous types cyclic effects, especially inherent in several regions world, is alternating impact wetting and drying on concrete reinforced structures. In current scientific literature practice, there not enough fundamental applied information about resistance to variotropic concretes obtained by centrifugal compaction methods. The purpose study was investigate effect various ...

Protective coatings are commonly applied to automobiles, aircrafts, ships, railways, furniture, bridges, concretes, architectural constituents, industrial installations, and many other products that we encounter on a daily basis. Coating application in many of these products is primarily implemented to provide protection against harsh environments such as UV light, extreme temperatures, acid, a...

Adapted structures must be developed so that modern reactive powder concretes (RPC) can be incorporated into new construction projects in an efficient and logical way. The steps of this development, from the analysis of the material characteristics, to the determination of the structural requirements, to the arrival at an appropriate adapted structure are described. An Outlook on the developmen...

Using pseudoinfection of cell lines, we demonstrate that cell surface heparan sulfate is required for infection by human papillomavirus type 16 (HPV-16) and HPV-33 pseudovirions. Pseudoinfection was inhibited by heparin but not dermatan or chondroitin sulfate, reduced by reducing the level of surface sulfation, and abolished by heparinase treatment. Carboxy-terminally deleted HPV-33 virus-like ...

regarding the increasing demand for lightweight concrete especially lightweight structural concrete, and safety requirements underlined in 2800 iranian standard, research to achieve the optimized results in lightweight concrete production seems inevitable. since, one of the commonly used methods for producing the light eight concrete, utilizes the light weight aggregates with significant role i...

Cracked and un-cracked Brazilian disc specimens subjected to diametral compression were used for conducting fracture toughness and tensile strength experiments on a polymer concrete (PC) material. The value of mode I fracture toughness (KIc) was determined from the center- cracked Brazilian disc and the indirect tensile strength (σt) was obtained from the un-cracked Brazilian disc specimen. The...
