abstract: friction stir welding, a solid state innovative joining technique, is widely being used for joining aluminium alloys for aerospace, marine automotive and many other applications of commercial importance. fsw trials were carried out using a vertical machining centre (vmc) on aa6061 alloy. the main objective of the present work was to evaluate the weld processing parameter of friction s...

The Moving Pictures Show is a contemporary Australian ‘silent’ film company that screens films produced in the period from 1912 to 1929, with a 9-piece orchestral accompaniment. This article explores the ways in which music is chosen for the show both to heighten the audience’s aesthetic experience of the film and to abide by historical practice. It also describes the ways in which improvisatio...

In this paper, we propose a wide-viewing-angle three-dimensional integral imaging using a curved screen and a curved lens array. Elemental images are projected to the curved screen. Incorporation of the curved screen and the curved lens array instead of a conventional flat display panel and a flat lens array expands the viewing angle remarkably. In addition adopting barriers between a curved le...

This paper presents a systematic approach to develop the mathematical model for predicting the ultimate tensile strength, yield strength, and percentage of elongation of AA6351 aluminum alloy which is widely used in automotive, aircraft and defense Industries by incorporating (FSW) friction stir welding process parameter such as tool rotational speed, welding speed, and axial force. FSW has bee...

Oxygen is the most widely used therapeutic strategy to prevent and treat decompression sickness (DCS). Oxygen prebreathe (OPB) eliminated DCS in 20-kg swine after rapid decompression from saturation at 60 feet of seawater (fsw). However, hyperbaric oxygen (HBO) has risks. As oxygen partial pressure increases, so do its toxic effects. Central nervous system (CNS) oxygen toxicity is the most seve...

BACKGROUND Global literature indicates the burden of human immunodeficiency virus (HIV), syphilis and hepatitis C virus (HCV) has disproportionately affected cross-border migrant female sex workers (FSW). However, few studies reported the HIV risk among Vietnamese FSW at borderline areas in China. We examined five consecutive years of HIV, syphilis, and HCV prevalence and corresponding risk fac...

Friction Stir Welding (FSW) is a solid-state welding process, based on frictional and stirring phenomena, that offers many advantages with respect to the traditional welding methods. However, several parameters can affect the quality of the produced joints. In this work, an experimental approach has been used for studying and optimizing the FSW process, applied on 5754-H111 aluminum plates. In ...

Fig. 1 The R&S®FSW26 signal and spectrum analyzer with the R&S®FSW-K17 multicarrier group delay measurement option. The combination of low phase noise, large analysis bandwidth and state-of-the-art user interface makes the R&S®FSW a unique measuring instrument in its class. Equipped with the R&S®FSW-B160 analysis bandwidth extension, group delay measurements up to a bandwidth of 160 MHz can be ...

OBJECTIVES Access to reproductive healthcare, including contraceptive services, is an essential component of comprehensive healthcare for female sex workers (FSW). Here, we evaluated the prevalence of and factors associated with contraceptive use, unplanned pregnancy, and pregnancy termination among FSW in three transit towns in Zambia. STUDY DESIGN Data arose from the baseline quantitative s...
