This survey presents a literature review on friction stir welding (FSW) modeling with a special focus on the heat generation due to the contact conditions between the FSW tool and the workpiece. The physical process is described and the main process parameters that are relevant to its modeling are highlighted. The contact conditions (sliding/sticking) are presented as well as an analytical mode...

OBJECTIVE To ascertain the cost effectiveness of targeted interventions for female sex workers (FSW) under the National AIDS Control Programme in India. METHODS A compartmental mathematical Markov state model was used over a 20-year time horizon (1995-2015) to estimate the cost effectiveness of FSW targeted interventions, with a health system perspective. The incremental costs and effects of ...

BACKGROUND Since 2000, peer-mediated interventions among female sex workers (FSW) in Mombasa Kenya have promoted behavioural change through improving knowledge, attitudes and awareness of HIV serostatus, and aimed to prevent HIV and other sexually transmitted infection (STI) by facilitating early STI treatment. Impact of these interventions was evaluated among those who attended peer education ...

OBJECTIVES To estimate HIV prevalence and risk factors in population-based samples of female sex workers (FSW) and female voluntary counseling and testing (VCT) clients in Rwanda. METHODS We conducted a cross-sectional survey of 800 FSW and 1,250 female VCT clients in Rwanda, which included interviewing and testing for HIV-1/2, HSV-2 and pregnancy, and BED-CEIA and Avidity Index (AI) to ident...

Two subjects carried out a saturation dive to 600 FSW with excursions to 800 feet of seawater (FSW). Two other subjects performed a saturation dive to 800 FSW. Both divers carried out two short excursion dives to 1050 and 1112 FSW followed later by an excursion dive to 1000 FSW lasting for 2-3/4 hours. All four divers noted helium tremors during their first excursion dive at depth exceeding 600...

OBJECTIVES To examine the impact of a large-scale HIV prevention programme for female sex workers (FSW) in Karnataka state, south India, on the prevalence of HIV/sexually transmitted infections (STI), condom use and programme coverage. METHODS Baseline and follow-up integrated biological and behavioural surveys were conducted on random samples of FSW in five districts in Karnataka between 200...

In spite of many modifications to decompression algorithms, the incidence of decompression sickness (DCS) in scuba divers has changed very little. The success of stage, compared to linear ascents, is well described yet theoretical changes in decompression ratios have diminished the importance of fast tissue gas tensions as critical for bubble generation. The most serious signs and symptoms of D...

OBJECTIVES Female sex workers (FSW) often have unprotected sex. Emergency contraceptive pills (ECP) are an important back-up method to prevent unwanted pregnancy among FSW. We examine ECP use among FSW in Swaziland. METHODS Using data from a 2011 respondent-driven sampling survey of 325 Swazi FSW, we explored the association between individual characteristics and ever having used ECP. RESUL...

This study aimed to investigate the chloride-binding capacity of alkali-activated fly ash (denoted as FSW) and slag (denoted as SSW) samples and their synthesized Cl-bearing phases, which are capable of binding and immobilizing chloride when seawater is used as the mixing water. This study also examined the progressive changes in the pore structures of the FSW and SSW samples over time. The res...

BACKGROUND Cervical cancer is the most prevalent cancer among Peruvian women. Female sex workers (FSW) in Peru are at elevated risk for HPV infection, and receive annual Papanicolaou screening. The objective of this study was to identify barriers to follow-up for abnormal Pap smears among FSW in Peru. METHODS 97 FSW attending the Alberto Barton Health Center in Lima were surveyed regarding th...
