fiber reinforced polymers (frp) have widely used for the purposes of enhances strength and ductility of concrete columns. proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with frp. in this paper, the influence of frp thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reacti...

The GRIN technologies (-geno, -robo, -info, -nano) promise to change the inner constitution of human body and its own existence. This transformation involves the structure of our lives and represent a –brave?– new world that we have to explore and to manage. In this sense, the traditional tools of humanism seems very inadequate to think the biotech century and there is a strong demand of a new ...

pervious concrete is a concrete mixture prepared from cement, aggregates, water, little or no fines, and in some cases admixtures. the hydrological property of pervious concrete is the primary reason for its reappearance in construction. much research has been conducted on plain concrete, but little attention has been paid to porous concrete, particularly to the analytical prediction modeling o...

Rowan et al.’s target article is an outstanding review of some the history science sentience, but one would have liked to see a much stronger “call action.” We don’t need any more data know that many other animals are sentient beings whose lives must be protected from harm in wide variety contexts. It not anti-science want action on behalf right now.

Starting from the twelfth century, Netherlands experienced substantial socioeconomic change. Several towns expanded in terms of size and industrial production, making gap between rich poor even greater. Access to certain resources (e.g., food, living spaces, etc.) became largely dependent on status, with being able afford an overall better lifestyle than poor. The aim this study was determine w...

the strength of concrete is a function of the proportions of the constituent materials, namely, cement, water, fine and coarse aggregates. the conventional methods used to determine the mix proportions that will yield the desired strength, are laborious, time consuming and expensive. in this paper, a mathematical method based on modified regression theory is formulated for the prediction of con...

Nanotechnology will serve as a suitable solution to achieve high performance in future construction and construction. Using this new technology, creativity and innovation can be achieved in the building industry. one of these new technologies of smart concrete is that in recent years, many researches and experiments have been done in scientific research centers around the world, so that the con...

The field of human-computer interaction (HCI) presents an enormous theoretical challenge to researchers trying to establish it as an integrated field of studies. To become such a field, HCI should be based on a conceptual scheme powerful enough to incorporate both human beings and computer technology within a coherent theoretical framework. One possible solution is based on the cognitive approa...
