This study compares the injecting and sexual risk-behaviour of young injectors, with injectors over the age of 25. All respondents presented for the first time at the Merchants' Quay Health Promotion Unit between May 1st 1997 and February 28th 1998. Analysis revealed that the young injectors were significantly more likely to report recently borrowing and lending used injecting equipment, and in...

Intensification of modern swine production has led to many new technologies, including needleless injectors. Although needleless injectors may increase productivity (by reducing injection time) and reduce needlestick injuries, the effect on risk for musculoskeletal disorders is not clear. This project will compare conventional needles with needleless injectors in terms of cost, productivity, in...

Abstract. We describe here a new method to increase the peak current of high brightness electron beams as those required to drive X-ray SASE FEL's, that is based on a rectilinear compressor scheme utilizing the bunching properties of slow waves. It is shown that whenever a beam, slower than the synchronous velocity, is injected into a RF wave at the zero acceleration phase and slips back in pha...

Abstract Let $$\pi $$ ? be a set of primes. We show that -separable groups have conjugacy class $${\mathfrak {F}}$$ F -injectors for suitable Fitting classes , which coincide with the usual ones when specializing to soluble groups.

A new understanding of the deposition of in situ boron doped polysilicon based on a comparison between experimental results and modeling predictions, is proposed. The depletion of both silane and boron trichloride is put in evidence and the necessity of the use of injectors is established. 1 Introduction The in situ doping of polysilicon is of interest /I/, as this technique makes it possible t...

W et injection was first proposed for administering inI sulin over 35 years ago (1). The stated rationale for I the initial devices was to decrease pain of injection I compared to needles and syringes (2). There was W little further application of jet injection to the treatment of diabetes for over 10 years, although jet injection developed wide use for mass immunization programs. Recently, the...
