Producing pulses in the southern agricultural region
The development of pulses in Western Australia has undergone tremendous advances over the past 12 years. From a tiny industry in the early 1990’s where the knowledge of both scientists and farmers was very limited, we now have a robust industry with production packages and improved varieties for all the grain legumes species that are well suited to our environment.
This book, which is both comprehensive and practical, collates much of the information gathered through pulse research and commercial experience over the past 10 years and will be valuable to all pulse growers, agronomists, students and industry advisors alike. The knowledge presented in this book has resulted from the dedicated efforts of scientists and industry specialists in Western Australia, working hand-in-hand with leading farmers, together with generous funding from the State Government and the Grains Research and Development Corporation (GRDC).https://researchlibrary.agric.wa.gov.au/bulletins/1154/thumbnail.jp
Producing pulses in the northern agricultural region
Pulses, like most other temperate crops, are ideally suited to environments with mild temperatures, adequate rainfall and free draining soils that have a deep uniform profile, a medium to fine texture and slightly acid to neutral pH (6.5-7.5). Pulses when grown on these soils and in these environments produce reliable yields, are relatively easy to manage and achieve good returns on investment.
Pulses can be grown very successfully in less ideal situations, but must then be managed carefully to ensure reliable yields. The different pulse species, and even different varieties of the same species, vary in how tolerant they are of less than ideal conditions. Understanding how pulses respond to soil and environment will make it easier to successfully manage crops in the range of situations occurring in the northern agricultural region.https://researchlibrary.agric.wa.gov.au/bulletins/1157/thumbnail.jp
Emission-line profile modelling of structured T Tauri magnetospheres
We present hydrogen emission line profile models of magnetospheric accretion
onto Classical T Tauri stars. The models are computed under the Sobolev
approximation using the three-dimensional Monte Carlo radiative-transfer code
TORUS. We have calculated four illustrative models in which the accretion flows
are confined to azimuthal curtains - a geometry predicted by
magneto-hydrodynamical simulations. Properties of the line profile variability
of our models are discussed, with reference to dynamic spectra and
cross-correlation images. We find that some gross characteristics of observed
line profile variability are reproduced by our models, although in general the
level of variability predicted is larger than that observed. We conclude that
this excessive variability probably excludes dynamical simulations that predict
accretion flows with low degrees of axisymmetry.Comment: 14 pages, 12 figures. Published in MNRA

An evaluation of a project aimed at increasing participation of young women in STEM activities and training in Wales
This case study reports on the delivery and impact of a European Union funded project in Wales. STEM Cymru 2 encourages participation in engineering activities and improvements in Science, Technology, Engineering and Mathematics (STEM) skills for young people aged between 11 and 19 years. Five different activities are delivered, including one which directly targets females aged 12-16 years to raise awareness of study and career opportunities in this field. An independent evaluation of the project was conducted, with a sample of participants and school representatives consulted individually and in focus groups. The evaluation discovered that female participants and their teachers welcomed female only activities which contributed to challenging stereotypes, resulting in reports of improvement in confidence, and increased awareness of related higher education courses and career routes. Female participants also reported improvement in transferable skills such as communication, teamwork and problem-solving following engagement with project activities. Another achievement for the project included female participants delivering Science and Technology activities and acting as role models for younger females in their school following their engagement with the project
Urban football narratives and the colonial process in Lourenço Marques
Support for Portuguese football teams, in Mozambique as well as in other former
Portuguese colonies, could be interpreted either as a sign of the importance of a
cultural colonial heritage in Africa or as a symbol of a perverse and neo-colonial
acculturation. This article, focused on Maputo, the capital of Mozambique –
formerly called Lourenc¸o Marques – argues that in order to understand
contemporary social bonds, it is crucial to research the connection between the
colonial process of urbanisation and the rise of urban popular cultures. Despite
the existence of social discrimination in colonial Lourenc¸o Marques, deeply
present in the spatial organisation of a city divided between a ‘concrete’ centre
and the immense periphery, the consumption of football, as part of an emergent
popular culture, crossed segregation lines. I argue that football narratives, locally
appropriated, became the basis of daily social rituals and encounters, an element
of urban sociability and the content of increasingly larger social networks.
Therefore, the fact that a Portuguese narrative emerged as the dominant form of
popular culture is deeply connected to the growth of an urban community
A new integrated care pathway for ambulance attended severe hypoglycaemia in the East of England: The Eastern Academic Health Science Network (EAHSN) model
Aims: We developed a new clinical integrated pathway linking a regional Ambulance Trust with a severe hypoglycaemia (SH) prevention team. We present clinical data from the first 2,000 emergency calls taken through this new clinical pathway in the East of England. Methods: SH patients attended by Ambulance crew receive written information on SH avoidance, and are contacted for further education through a new regional SH prevention team. All patients are contacted unless they actively decline. Results: Median age (IQR) was 67 (50 - 80) years, 23.6% of calls were for patients over 80 years old, and patients more than 90 years old were more common than 20 - 25 year olds in this population. Most calls were for patients (84.9%) who were insulin treated, even those over 80 years (75%). One - third of patients attended after a call were unconscious on attendance. 5.6% of patients in this call population had 3 or more ambulance call outs, and they generated 17.6% of all calls. In total, 728 episodes (36.4%) were repeat calls. Insulin related events were clinically more severe than oral hypoglycaemic related events. Patients conveyed to hospitals (13.8%) were significantly older, with poorer recovery in biochemical hypoglycaemia after ambulance crew attendance. Only 19 (1%) opted out of further contact. Patients were contacted by the SH prevention team after a median 3 (0 - 6) days. The most common patient self - reported cause for their SH episode was related to percieved errors in insulin management (31.4%). Conclusions: This new clinical service is simple, acceptable to patients, and a translatable model for prevention of recurrent SH in this largely elderly insulin treated SH population
MSX Mid infrared imaging of massive star birth environments. II: Giant HII regions
We conduct a Galactic census of Giant HII regions, based on the all sky 6cm
dataset of Kuchar & Clark, plus the kinematic distances obtained by Russeil.
From an inspection of mid-IR Mid-course Space Experiment (MSX) and far-IR
IRAS Sky Survey Atlas images we identify a total of 56 GHII regions in the
Milky Way, of which 15% (65%) can be seen at optical (near-IR) wavelengths.The
mid to far-IR fluxes from each GH {\sc ii} region are measured, and sample the
thermal emission from the ubiquitous dust present within the exciting clusters
of OB stars, arising from the integrated luminosity of the hot stars heating
the cluster dust, for which we obtain log L(IR)=5.5-7.3 L_sun. The mid-IR
21micron spatial morphology is presented for each GHII region, and often
indicates multiple emission sources, suggesting complicated cluster formation.
IR colour-colour diagrams are presented, providing information about the
temperature distribution and optical depth of the dust. For the clusters of our
study, the dust is not optically thick to all the stellar radiation, thus the
measured infra-red luminosity is lower than the L(bol). As the dust environment
of a cluster begins to dissipate, the thermal emission and its optical depth
ought to decrease even before the stars appreciably evolve. We see evidence of
this in our empirical relationship between the integrated IR and Lyman
continuum luminosities.Comment: 11 pages, 3 figures (+ 10 figures for electronic edition). Accepted

Interstellar polarization and grain alignment: the role of iron and silicon
We compiled the polarimetric data for a sample of lines of sight with known
abundances of Mg, Si, and Fe. We correlated the degree of interstellar
polarization and polarization efficiency (the ratio of to the colour
excess or extinction ) with dust phase abundances. We detect an
anticorrelation between and the dust phase abundance of iron in non
silicate - containing grains ]_\rm d, a correlation
between and the abundance of Si, and no correlation between or
and dust phase abundances. These findings can be explained if mainly
the silicate grains aligned by the radiative mechanism are responsible for the
observed interstellar linear polarization.Comment: Accepted for publication in Astronomy and Astrophysic
