OBJECTIVES To compare demographic, HIV risk behaviors, and health status characteristics of injection drug users (IDUs) who have injected "crack" cocaine with IDUs who have not. METHODS Nine hundred and eighty-nine IDUs were recruited in New Haven, CT, Hartford, CT and Springfield, MA from January 2000 to May 2002. Participants were administered a modified version of the National Institute on...
BACKGROUND This study was conducted to investigate type 2 diabetes mellitus (T2DM) patient perceptions of their pen injectors and determine which features were deemed most important to overall satisfaction. METHODS Frost & Sullivan conducted a Web-based survey of T2DM patients in the United States in November 2010. Survey participants were initially screened prior to full participation. A tot...
High pressure amount of fuel in new generation diesel engines’ injector equipped with multiple and small nozzle holes has created significant improvement in the outgoing spray behavior and engine performance. On the other hand, poor fuel quality and injector nozzle embedded in high temperature combustion chamber form fundamental deposits on the nozzle leading to fuel spray inappropriate behavio...
BACKGROUND Injection drug use is steadily rising in Kenya. We assessed the prevalence of both human immunodeficiency virus type 1 (HIV-1) and hepatitis C virus (HCV) infections among injecting heroin users (IHUs) at the Kenyan Coast. METHODS A total of 186 IHUs (mean age, 33 years) from the Omari rehabilitation center program in Malindi were consented and screened for HIV-1 and HCV by serolog...
This study funded by Centers for Disease Control compares HIV prevalence and risk behavior among heterosexual methamphetamine (n = 428) and nonmethamphetamine (n = 878) injectors in California, USA, during 2001-2003. While HIV was not highly prevalent among methamphetamine injectors (3%), sexual and injection risk behaviors were highly prevalent (ranging from 21% to 72%). In multivariate analys...
We estimated the prevalence of HIV, HBV and HCV infections among injecting and noninjecting drug users treated within public drug-treatment centres in Italy to determine the correlates of infection. In the sample of 1330 drug users, the prevalence of HIV was 14.4% among drug injectors and 1.6% among non-injectors; the prevalence of HBV was 70.4% among injecting drug users and 22.8% among non-in...
An experimental system for serial femtosecond crystallography using an X-ray free-electron laser (XFEL) has been developed. It basically consists of a sample chamber, fluid injectors and a two-dimensional detector. The chamber and the injectors are operated under helium atmosphere at 1 atm. The ambient pressure operation facilitates applications to fluid samples. Three kinds of injectors are em...
In this paper, the effect of secondary fluid injection on deviation and control of thrust vector with use of sprayed liquid fluid multi injection in to divergence nozzle flow is studied. Freon fluid as injection fluid have been chosen that more applicable and the fluent software is used for simulation flow field. In this investigation after grid study, different simulations in order to obtain t...
The United Kingdom has not seen the major spread of HIV-1 infection among drug injectors that was anticipated in the mid-1980s. Although cities in many countries have seen rapid spread of HIV-1 infection to epidemic levels (40% prevalence and above), the United Kingdom is one of several countries that experiences low and stable prevalence rates. Since the mid-1980s there have been major changes...
