Objectives. This study examined correlates of condom use among 248 female sex workers (FSW) in The Gambia. Methods. Between July and August 2011, FSW in The Gambia who were older than 16 years of age, the age of consent in The Gambia, were recruited for the study using venue-based sampling and snowball sampling, beginning with seeds who were established clients with the Network of AIDS Services...

This article presents a method for automatic seam-tracking in friction stir welding (FSW) of lap joints. In this method, tracking is accomplished by weaving the FSW tool back-and-forth perpendicular to the direction of travel during welding and monitoring force and torque signals. Research demonstrates the ability of this method to automatically track weld seam positions. Additionally, tensile ...

The Family Stories Workshop (FSW) is a process through which family members and friends of persons with dementing disorders living in nursing homes develop stories of these residents' lives. The stories are meant to help staff members to develop a better, more deeply felt understanding of the lives of the residents, persons who can no longer tell their own stories. The workshop is product-orien...

A three-dimensional heat transfer model for friction stir welding (FSW) is presented in this paper; a moving coordinate is introduced to reduce the difficulty of modeling the moving tool. Heat input from the tool shoulder and the tool pin are considered in the model. The finite difference method was applied in solving the control equations. A non-uniform grid mesh is generated for the calculati...

A three-dimensional numerical model is used to simulate the Friction Stir Welding (FSW) process using the computational fluid dynamics package ‘FLUENT’. Two mechanical models: the Couette and the Visco-Plastic fluid flow models for Al-6061-T6 were simulated. The simulation results are compared to experimental data for Al 6061-T6 welded at high rotational (1500–5000 rpm) and travel speeds rangin...

A spacecraft simulation environment was developed for testing distributed spacecraft flight software (FSW) designed for autonomous coordinated control of a spacecraft cluster. The Cluster Flight Application (CFA) FSW was developed by Emergent Space Technologies in support of the Defense Advanced Research Projects Agency (DARPA) System F6 Program. The CFA provides cluster flight guidance, naviga...

BACKGROUND In a study of female sex workers (FSW) servicing truck driver clients in Mexican border cities, we evaluated differences in HIV/STI risk behaviors by workplace. METHODS Cross-sectional study of FSW servicing truck drivers in Mexico: 100 from Nuevo Laredo (U.S. border); 100 from Ciudad Hidalgo (Guatemalan border). Main outcome was unstable workplace, defined as primary place of sex ...

The relevance, importance and presence of industrial robots in manufacturing have increased over the years, with applications in diverse new and nontraditional manufacturing processes. This paper presents the complete concept and design of a novel friction stir welding (FSW) robotic platform for welding polymeric materials. It was conceived to have a number of advantages over common FSW machine...

INTRODUCTION Although interventions to control HIV among high-risk groups such as female sex workers (FSW) are highly recommended in Africa, the contents and efficacy of these interventions are unclear. We therefore designed a comprehensive dedicated intervention targeting young FSW and assessed its impact on HIV incidence in Burkina Faso. METHODS Between September 2009 and September 2011 we ...

BACKGROUND In 1997, a survey in Kisumu found a prevalence of HIV infection among female sex workers (FSW) of 75%. Only 50% reported using a condom with the last client. In 2008, we conducted another survey to collect data to inform an intervention targeting FSW in Kisumu. METHODS In 2008 FSW were recruited by respondent-driven sampling. Women completed a questionnaire and were tested for HIV ...
