BACKGROUND Specialised sexually transmitted infection (STI) clinics in the Netherlands provide STI care for high-risk groups, including female sex workers (FSW), at the clinic and by outreach visiting commercial sex workplaces with a permit. The objective was to investigate the STI positivity rate and determinants of an STI diagnosis among FSW tested by STI clinics in the Netherlands. METHODS...

OBJECTIVE This systematic review aims to synthesize articles, abstracts and reports of HIV prevalence studies conducted among men who have sex with men (MSM) and female sex workers (FSW) in Latin America and the Caribbean (LAC). MATERIALS AND METHODS Authors searched online databases and collected gray literature on HIV prevalence among MSM and FSW from LAC. Year, location, sampling methodolo...

Protection against decompression sickness (DCS) by acclimation to hyperbaric decompression has been hypothesized but never proven. We exposed rats to acclimation dives followed by a stressful "test" dive to determine whether acclimation occurred. Experiments were divided into two phases. Phase 1 rats were exposed to daily acclimation dives of hyperbaric air for 30 min followed by rapid decompre...

BACKGROUND This study examined cross-sectional data collected from substance-using female sex workers (FSW) and non-sex workers (non-SW) in Pretoria, South Africa, who entered a randomized controlled trial. METHODS Women who reported alcohol use and recently engaging in sex work or unprotected sex were recruited for a randomized study. The study sample (N = 506) comprised 335 FSW and 171 fema...

While brothel-based sex work is regulated by the Peruvian government, there is little data on STI risk factors reported by female sex workers (FSW). This study compared high risk behaviors among 120 Peruvian FSW from government regulated brothels with both clients and non-commercial partners. Our study found that 12% of FSW reported unprotected vaginal sex with clients (compared to 75% with non...

Friction stir welding process is a relatively recent welding process (patented in 1991). FSW is a solid-state joining process during which materials to be joined are not melted. During the FSW process, the behaviour of the material is at the interface between solid mechanics and fluid mechanics. In this paper, a 3D numerical model of the FSW process with a non-cylindrical tool based on a solid ...

Although friction stir welding (FSW) has made its way to industrial application particularly in the last years, the FSW process, its influences and their strong interactions among themselves are still not thoroughly understood. This lack of understanding mainly arises from the adverse observability of the actual process with phenomena like material flow and deposition, large material deformatio...

This paper describes HIV seroprevalence, knowledge of HIV transmission, and condom use among female sex workers (FSW) attending five specialized sexually transmitted disease (STD) clinics in Santiago, Chile. A short questionnaire with socio-demographic, AIDS knowledge, and condom-use variables was administered to 626 FSW. HIV seroprevalence was estimated with a blood test sent to the Chilean Pu...

This work deals with the modeling of the material flow in Friction Stir Welding (FSW) processes using particle tracing method. For the computation of particle trajectories, three accurate and computationally efficient integration methods are implemented within a FE model for FSW process: the Backward Euler with Substepping (BES), the 4-th order Runge-Kutta (RK4) and the Back and Forth Error Com...

Friction stir welding (FSW) is a widely used solid state joining process for soft materials such as aluminium alloys because it avoids many of the common problems of fusion welding. Commercial feasibility of the FSW process for harder alloys such as steels and titanium alloys awaits the development of cost effective and durable tools which lead to structurally sound welds consistently. Material...
