Deoxyribonucleic Acid (DNA) has been recently found to be an efficient renewable and environmentally-friendly flame retardant. In this work, for the first time, we have used waste DNA from fishing industry to modify clay structure in order to increase the clay interactions with epoxy resin and take benefit of its additional thermal property effect on thermo-physical properties of epoxy-clay nan...

Hybrids based on recycled high density polyethylene (RHDPE) and organic clay were made by melt compounding. The influence of blending method, compatibilizers, and clay content on clay intercalation and exfoliation, RHDPE crystallization behavior, and the mechanical properties of RHDPE/clay hybrids were investigated. Both maleated polyethylene (MAPE) and titanate could improve the compatibilizat...

A controlled greenhouse experiment was conducted to study the fraction, uptake and fixation of phosphorus (P) and potassium (K) in three soils with contrasting characteristics. The experiment was carried out in two phases, viz., sorghum-Sudangrass depletion and test crop experiment with maize with three levels of fertility status (depleted, original and fertilized with 40 mg kg-1 P and K) and t...

Most of oil and gas offshore platforms are located in the seismic regains. So, Seismic vulnerability evaluation of the offshore platforms is one of the most important and vital issues in the structural systems. In this study, jacket type offshore platforms are studied by incorporating the pushover analyses and nonlinear time history analyses, in such a way that, first some push over analyses ar...

IT offshore outsourcing means using an offshore provider to handle some of an enterprise’s IT work. Offshore outsourcing now has a track record, so it has become an option that IT leaders need to consider. But the practice has raised the issue of how to manage expertise dispersed across sites. Both clients and providers now realize that knowledge management is an important contributor to succes...

The mechanical and electrical characteristics of films, buckypapers and fiber materials from combinations of clay, carbon nanotubes (CNTs) and chitosan are described. The rheological time-dependent characteristics of clay are maintained in clay-carbon nanotube-chitosan composite dispersions. It is demonstrated that the addition of chitosan improves their mechanical characteristics, but decrease...

Behavioral risks such as shirking and misappropriation of information assets are more prominent in offshore software development context and could adversely affect offshore outsourcing success. This paper studies the moderating effects of different relational norms on the link between behavioral risks and offshore software development success. We focused on three major modes of relational norms...

Aimed at the practical requirement of tubular joint welds inspection of offshore platform structures, the ultrasonic phased array inspection algorithm for offshore platform structures is proposed in this paper, and the ultrasonic phased array inspection system for offshore platform structures is developed. The experiment of tubular joint model is performed with the ultrasonic phased array inspe...

The influence of clay preparation methods on the sorption and hydrolysis of carbaryl (1-naphthyl, N-methyl carbamate) by K+-saturated reference smectite SWy-2 was studied. Four methods were utilized: (1) The reference (or specimen) clay used as received was K+-saturated (hereafter referred to as whole clay). (2) High-speed centrifugation (3295g) of whole clay resulted in a pellet with three dis...
