The relative contributions of needle use practices and sexual behaviors to human immunodeficiency virus (HIV) antibody seropositivity among 394 women incarcerated in Quebec were determined by risk factor assessment and serology with a nonnominal methodology. HIV positivity was found in 6.9% (95% confidence interval [CI] = 4.6, 9.9) of all participants and(More)
This paper presents a new technique of electrical energy generation using mechanically excited piezoelectric materials and a nonlinear process. This technique, called synchronized switch harvesting (SSH), is derived from the synchronized switch damping (SSD), which is a nonlinear technique previously developed to address the problem of vibration damping on(More)
OBJECTIVE To identify, describe and characterize the patient and physician participation in content production in medication-related exchanges during primary care consultations. METHODS Descriptive study of audio recordings of 422 medical encounters. MEDICODE, a validated instrument was used to analyze verbal exchanges on medications. Two main indicators(More)
This paper compares the performances of vibration-powered electrical generators using a piezoelectric ceramic and a piezoelectric single crystal associated to several power conditioning circuits. A new approach of the piezoelectric power conversion based on a nonlinear voltage processing is presented, leading to three novel high performance power(More)
OBJECTIVE To describe the exchanges, related to discussion of all medications during primary care medical consultations. METHODS Descriptive study of audio recordings of 422 medical encounters. Coding was done with MEDICODE, a validated instrument developed to analyse verbal exchanges on medications. The unit of analysis is the medication. RESULTS An(More)
OBJECTIVE To describe the challenges for immigrant patients and their physicians and their skills in intercultural communication (ICC). METHODS We videotaped one clinical encounter for each of 24 psychologically distressed patients visiting their regular family physician. The physician and the patient, each separately, viewed the videotape of their(More)
INTRODUCTION Interpreters often join immigrants and physicians to permit communication. OBJECTIVE To describe the content of talk about health problems and medications during clinical encounters involving interpreters [professionals (PI) or family members (FI)]. METHODS We analysed one regularly scheduled encounter for each of 16 adult patients with his(More)
—Harvesting energy from ambient sources has become of great importance these last few years. This can be explained not only by advances in microlectronics and energy harvesting technologies, but also by a growing industrial demand in wireless autonomous devices. In this field, piezoelectric elements offer outstanding performances, thanks to their high power(More)
