The paper presents a method of testing piezoelectric fuel injectors in modern common rail systems, which allows them to be repaired almost the full extent. obtained results indicate that this process can effectively carried out, even taking into account existing technological limitations. most important stages implemented activities are specified, first all scope required maintenance pre- and p...

In the present study, ablation of a pintle injector on 500N GOX/GCH4 rocket engine under different working conditions is studied experimentally and numerically. The temperature tip combustion gas in head zone was measured series experiments by thermocouples. Moreover, three-dimensional model established to simulate heat transfer concurrently analyze state injectors. obtained results indicate th...

BACKGROUND People who inject drugs (PWID) are a key population affected by HIV. We assessed the effectiveness of HIV treatment among a clinical cohort of people living with HIV (PLHIV) diagnosed and referred for community-based antiretroviral therapy (ART) in Victoria, Australia. METHODS HIV notification data from a central statewide registry were matched with HIV clinical data from two large...

BACKGROUND Personal networks are significant social spaces to spread of HIV or other blood-borne infections among hard-to-reach population, viz., injecting drug users, female sex workers, etc. Sharing of infected needles or syringes among drug users is one of the major routes of HIV transmission in Manipur, a high HIV prevalence state in India. This study was carried out to describe the network...

OBJECTIVE To describe drug use, sexual risks and the prevalence of blood-borne viral infections among men who inject image and performance enhancing drugs (IPEDs). DESIGN A voluntary unlinked-anonymous cross-sectional biobehavioural survey. SETTING 19 needle and syringe programmes across England and Wales. PARTICIPANTS 395 men who had injected IPEDs. RESULTS Of the participants (median ...

13th Australasian Fluid Mechanics Conference Monash University, Melbourne, Australia 13-18 December 1998 Experiments which visualise the fuel-mixture-fraction for different types of fuel injectors considered for use in supersonic combustors are described. The flowfields of two different fuel injectors are compared in a qualitative manner. INTRODUCTION Successful development of a supersonic comb...
