The effect of the microstructure heterogeneity on the tensile plastic deformation characteristic of friction-stir-welded (FSW) dual-phase (DP) steel was investigated for the potential applications on the lightweight design of vehicles. Friction-stir-welded specimens with a butt joint configuration were prepared, and quasi-static tensile tests were conducted, to evaluate the tensile properties o...

OBJECTIVES HIV prevalence among Cambodian female sex workers (FSW) is among the highest in Southeast Asia. We describe HIV prevalence and associated risk exposures in FSW sampled serially in Phnom Penh, Cambodia (Young Women's Health Study (YWHS)), before and after the implementation of a new law designed to combat human trafficking and sexual exploitation. DESIGN Cross-sectional analysis of ...

OBJECTIVES We examined if increased spending and coverage of female sex worker (FSW) interventions were associated with declines in HIV or syphilis risk among young pregnant women (as a proxy for new infections in the general population) in the high-burden southern states of India. DESIGN Repeated cross-sectional analysis. SETTING We used logistic regression to relate district-level spendin...

Title: Factors associated with history of drug use among female sex workers (FSW) in a high HIV prevalence state of India

HYPOTHESIS This study investigated whether pressure changes common to scuba diving and to hyperbaric oxygen therapy would not cause crush damage or leakage from critical seals in commercially available cochlear implants. BACKGROUND The implanted packages of cochlear implants are susceptible to electrical failure caused by leakage from critical seals and to crush injury when exposed to changin...

OBJECTIVES To describe the size and distribution of female sex worker (FSW) populations and the distribution of client-FSW encounters in seven major cities of Pakistan. METHODS Mapping of FSWs was done using a two-stage process of identifying and validating locations where FSWs solicit and/or meet clients, estimating the size of the FSW population at each location and describing the type of s...

INTRODUCTION Hyperbaric oxygen (HBO2) multiplace chamber inside attendants (IAs) are at risk for decompression sickness (DCS). Standard decompression tables are formulated for sea-level use, not for use at altitude. METHODS At Presbyterian/St. Luke's Medical Center (Denver, Colorado, 5,924 feet above sea level) and Intermountain Medical Center (Murray, Utah, 4,500 feet), the decompression obl...

The study presents the hybrid joining of third generation AA2198-T8 aluminum lithium alloy to AA2024-T3 copper alloy, which has been highly demanded recently in aerospace industry. This investigation aims reduce cost production industrial sector. As a result, an affordable alternative is use designs using crucial parts and rest structure. A method required create structures composed last-genera...

BACKGROUND The Brazilian response towards AIDS epidemic is well known, but the absence of a systematic review of vulnerable populations horizontal line men who have sex with men (MSM), female sex workers (FSW), and drug users (DU) remains a main gap in the available literature. Our goal was to conduct a systematic review and meta-analysis of studies assessing HIV prevalence among MSM, FSW and D...

The purpose of this paper is to report quantitative data and models for the flow stress computer simulation friction stir welding (FSW). In paper, stresses commercial 6061 aluminum alloy at typical temperatures in FSW are investigated quantitatively by using hot compression tests. during determined reviewing literature data. measured stress, strain rate temperature tests fitted a Sellars–Tegart...
