“…Observationally, the answer is yes. Wilking et al (1997b) detected HH 313 in [S ii ], but not in H α emission. We do in fact find that the infrared extinction at the head of the bow (as observed in H 2 emission) is less than 2 mag.…”

“…VLA 1623A (distance ∼160 pc) is a compact, luminous H 2 feature associated with the highly collimated and extensive CO outflow driven by the prototypical low‐mass class 0 source VLA 1623 (André et al 1990; Dent, Matthews & Walther 1995; Yu & Chernin 1997). VLA 1623A has also recently been observed at optical wavelengths and consequently recognized as a bonafide Herbig–Haro object (HH 313: Wilking et al 1997b). The CO outflow, thought to be orientated at roughly 10° to the plane of the sky (André et al 1990), extends over almost 20 arcmin, knot A being only the brightest H 2 feature within this outflow.…”

We present a comprehensive near‐infrared study of two molecular bow shocks in two protostellar outflows, HH 99 in R Coronae Australis and VLA 1623A (HH 313) in Rho Ophiuchi. New, high‐resolution, narrow‐band images reveal the well‐defined bow shock morphologies of both sources. These are compared with two‐dimensional MHD modelling of molecular bows from which we infer flow inclination angles, shock speeds and the magnetic field in the pre‐shock gas in each system. With combined echelle spectroscopy and low‐resolution K‐band spectra we further examine the kinematics and excitation of each source. Bow shock models are used to interpret excitation (CDR) diagrams and estimate the extinction and, in the case of VLA 1623, the ortho–para ratio associated with the observed H2 population. For the first time, morphology, excitation and kinematics are fitted with a single bow shock model. Specifically, we find that HH 99 is best fitted by a C‐type bow shock model (although a J‐type cap is probably responsible for the [Fe ii] emission). The bow is flowing away from the observer (at an angle to the line of sight of ∼45°) at a speed of roughly 100 km s−1. VLA 1623A is interpreted in terms of a C‐type bow moving towards the observer (at an angle to the line of sight of ∼75°) at a speed of ∼80 km s−1. The magnetic field associated with HH 99 is thought to be orientated parallel to the flow axis; in VLA 1623A the field is probably oblique to the flow axis, since this source is clearly asymmetric in our H2 images.

“…As such, the practice should be refined and pursued. Improvements in short‐term results may ultimately depend on accurate means of testing organ viability and exploring new possibilities to stabilize NHBD so that less injured organs may be retrieved and transplanted [34].…”

Objective -To determine the relative admission rates of Asian and non-Asian patients to intensive therapy units (ITUs) in Coventry and to explore the implications of these rates for the transplantation of organs to Asian people. Design -Examination of 1991 census data and a retrospective review of ITU admissions books. Data were collected on ethnic background, presenting diagnosis, and clinical outcome for each admission.
