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
Precision tools and models to narrow in on the 750 GeV diphoton resonance
The hints for a new resonance at 750 GeV from ATLAS and CMS have triggered a
significant amount of attention. Since the simplest extensions of the standard
model cannot accommodate the observation, many alternatives have been
considered to explain the excess. Here we focus on several proposed
renormalisable weakly-coupled models and revisit results given in the
literature. We point out that physically important subtleties are often missed
or neglected. To facilitate the study of the excess we have created a
collection of 40 model files, selected from recent literature, for the
Mathematica package SARAH. With SARAH one can generate files to perform
numerical studies using the tailor-made spectrum generators FlexibleSUSY and
SPheno. These have been extended to automatically include crucial higher order
corrections to the diphoton and digluon decay rates for both CP-even and CP-odd
scalars. Additionally, we have extended the UFO and CalcHep interfaces of
SARAH, to pass the precise information about the effective vertices from the
spectrum generator to a Monte-Carlo tool. Finally, as an example to demonstrate
the power of the entire setup, we present a new supersymmetric model that
accommodates the diphoton excess, explicitly demonstrating how a large width
can be obtained. We explicitly show several steps in detail to elucidate the
use of these public tools in the precision study of this model.Comment: 184 pages, 24 figures; model files available at

Trends and needs in the Australian child welfare workforce : An exploratory study
[Extract] Until recently, there has been limited focus on the nature and readiness of the broader child welfare workforce for stronger engagement in child abuse intervention and prevention, particularly the universal workforce. There is a concentration of effort and funding in the tertiary sector but there are now increasing calls to prioritise public health prevention.
An effective system of family supports, and early interventions entails an integration of programs and services across the three tiers of a public health system: primary, secondary and tertiary.
To support workers in ensuring the safety and wellbeing of children and young people, all organisations that offer services to vulnerable children, young people and families—directly or indirectly—need to be able to attract, recruit and sustain a reliable and appropriately qualified and skilled workforce.
This report presents findings from an exploratory study that examined broad-ranging, publicly available data to investigate emerging trends, issues and needs in the child welfare workforce and the educational profile of the workforce
The HIV-associated tuberculosis epidemic--when will we act?
Despite policies, strategies, and guidelines, the epidemic of HIV-associated tuberculosis continues to rage, particularly in southern Africa. We focus our attention on the regions with the greatest burden of disease, especially sub-Saharan Africa, and concentrate on prevention of tuberculosis in people with HIV infection, a challenge that has been greatly neglected. We argue for a much more aggressive approach to early diagnosis and treatment of HIV infection in affected communities, and propose urgent assessment of frequent testing for HIV and early start of antiretroviral treatment (ART). This approach should result in short-term and long-term declines in tuberculosis incidence through individual immune reconstitution and reduced HIV transmission. Implementation of the 3Is policy (intensified tuberculosis case finding, infection control, and isoniazid preventive therapy) for prevention of HIV-associated tuberculosis, combined with earlier start of ART, will reduce the burden of tuberculosis in people with HIV infection and provide a safe clinical environment for delivery of ART. Some progress is being made in provision of HIV care to HIV-infected patients with tuberculosis, but too few receive co-trimoxazole prophylaxis and ART. We make practical recommendations about how to improve this situation. Early HIV diagnosis and treatment, the 3Is, and a comprehensive package of HIV care, in association with directly observed therapy, short-course (DOTS) for tuberculosis, form the basis of prevention and control of HIV-associated tuberculosis. This call to action recommends that both HIV and tuberculosis programmes exhort implementation of strategies that are known to be effective, and test innovative strategies that could work. The continuing HIV-associated tuberculosis epidemic needs bold but responsible action, without which the future will simply mirror the past

Confronting Standard Models of Proto--Planetary Disks With New Mid--Infrared Sizes from the Keck Interferometer
We present near and mid-infrared interferometric observations made with the
Keck Interferometer Nuller and near-contemporaneous spectro-photometry from the
IRTF of 11 well known young stellar objects, several observed for the first
time in these spectral and spatial resolution regimes. With AU-level spatial
resolution, we first establish characteristic sizes of the infrared emission
using a simple geometrical model consisting of a hot inner rim and mid-infrared
disk emission. We find a high degree of correlation between the stellar
luminosity and the mid-infrared disk sizes after using near-infrared data to
remove the contribution from the inner rim. We then use a semi-analytical
physical model to also find that the very widely used "star + inner dust rim +
flared disk" class of models strongly fails to reproduce the SED and
spatially-resolved mid-infrared data simultaneously; specifically a more
compact source of mid-infrared emission is required than results from the
standard flared disk model. We explore the viability of a modification to the
model whereby a second dust rim containing smaller dust grains is added, and
find that the two-rim model leads to significantly improved fits in most cases.
This complexity is largely missed when carrying out SED modelling alone,
although detailed silicate feature fitting by McClure et al. 2013 recently came
to a similar conclusion. As has been suggested recently by Menu et al. 2015,
the difficulty in predicting mid-infrared sizes from the SED alone might hint
at "transition disk"-like gaps in the inner AU; however, the relatively high
correlation found in our mid-infrared disk size vs. stellar luminosity relation
favors layered disk morphologies and points to missing disk model ingredients
instead
