INTRODUCTION
This paper is an update of a previous paper authored by Mr. Humphry Udall, former
Director of Research and Development for Thermatool.
The welding of stainless steel tubes differs substantially from the welding of high quality
carbon steel tubes in a number of ways. The most significant difference is in the melting
point of the oxides that are formed on the faying edges during the welding process. The
oxides formed on carbon steel generally melt at a temperature lower than the melting
point of the steel. Since the oxi ....etc

concrete filled steel tubular structure

Abstract

Concrete-filled steel tubular (CFST) structure offers numerous structural benefits, and has been widely used in civil engineering structures. This paper reviews the development of the family of concrete-filled steel tubular structures to date and draws a research framework on CFST members. The research development on CFST structural members in most recent years, particularly in China, is summarized and discussed. The current design approaches from various countries are examined briefly. Some pr ....etc

ABSTRACT

Carbon nanotubes (CNTs) are a recently discovered allotrope of carbon. They take the form of cylindrical carbon molecules and have novel properties that make them potentially useful in a wide variety of applications in nanotechnology, electronics, optics, and other fields of materials science. They exhibit extraordinary strength and unique electrical properties, and are efficient conductors of heat. Inorganic nanotubes have also been synthesized. A nanotube is a member of the fullerene structural family, which also includes bucky ....etc

Abstract
Auto-focusing in imaging systems depends on
the determination of the correct image focus criterion. In this
research, the image captured by a liquid-filled diaphragm (LFD)
fluid lens was analyzed to determine a focus measure criterion
that can be used to establish the correct focus and thus quantify
the image quality. The LFD lens was actuated using a steppermotor
driven syringe mechanism. The lens diaphragm was made
of polydimethylsiloxane (PDMS) polymer that exhibit good
optical properties. The lens focal length was ....etc

The remarkable properties of carbon nanotubes may allow them to play a crucial role in the relentless drive towards miniaturization at the nanometre scale.

Nanotechnology is predicted to spark a series of industrial revolutions in the next two decades that will transform our lives to a far greater extent than silicon microelectronics did in the 20th century. Carbon nanotubes could play a pivotal role in this upcoming revolution if their remarkable electrical and mechanical properties can be exploited.

Since the first measurements were mad ....etc
