The value of alar sprays for apples
ALAR* is a growth retardant which has been die subject of intensive research in other countries. It tends to slow both fruit growth and ripening and to reduce shoot extension.
Overseas and local investigations with apples have shown that Alar will reduce preharvest drop, restrict shoot growth and increase flower bud formation for the following season
Stop-drop sprays for Jonathan and Delicious apples
STOP-DROP sprays prevent excessive pre-harvest drop of Jonathan and Delicious apples.
Recent research has thrown more light on the best methods of employing these materials.
TWO CHEMICALS used as stop-drop sprays are available commercially in Western Australia. One of these, alpha napthalene acetic acid (NAA), is also well known as a thinning spray for apples
Service-Learning in Deaf Studies: Integrating Academia and the Deaf Community
The pedagogy of Service-Learning is a new addition to the field of Deaf Studies. As a new and non-traditional course, the implementation of a Deaf Studies Service-Learning course is a challenging task. One challenge is to develop several multi-directional relationships between the faculty member, students, deaf consumers, and community partners from deaf- related rehabilitation agencies. Another issue is addressing the major challenges identified in the Service-Learning literature. Utilizing recommendations made by an experienced faculty member, these challenges are surmountable. This combination of in-class and out-of-class pedagogy enriches Deaf Studies students\u27 learning experience serving the deaf consumers in real world settings
Fertiliser recommendations for citrus : detailed fertilizer programmes for citrus growers
CITRUS growers should adopt a well balanced fertiliser programme to safeguard tree health, cropping and fruit quality. While moderate dressings are a wise insurance in most situations the rates required vary with tree age and soil type.
The recommendations are given in detail in the tables in this article
Fertiliser recommendations for apple trees
THE increased use of irrigation and chemical thinning in apple orchards and the planting of trees in light soils have resulted in responses to regular fertiliser dressings
A Case Study on Accessible Reading with Deaf Children
The concept of accessible reading for deaf students is new and worthy of exploration. In the face of the reading difficulties often experienced by deaf students, the lack of a specialized reading methodology that works for them must be addressed. Central to the paper is a research case study undertaken with two young deaf students, proficient in American Sign Language (ASL) and learning to read. The students participated in a tutorial with a tutor knowledgeable in a specialized reading methodology called ASL Gloss. The participating students demonstrated progress in reading skills over time. Two reading measures were adapted from English to ASL for use with deaf students. Some important features of ASL Gloss are included in the study report. The manipulated English text that closer resembles ASL and the use of the ASL-phabet, are designed to facilitate deaf students’ needed transition from ASL to English literacy (Supalla, 2017; Supalla & Cripps, 2011; Supalla et al., 2001). These deaf students engage in oral reading (in ASL) and are also given a different task. That is, to identify ASL-phabet letters that represent the phonological structure of signed words. The reading measures under development appear to promote the process of learning to read as informed by the quantitative and qualitative data. These findings support the need and promise of pursuing an alternative theory and applied research for deaf students’ reading that accounts for their ability to become fluent readers
Towards a modeling of the time dependence of contact area between solid bodies
I present a simple model of the time dependence of the contact area between
solid bodies, assuming either a totally uncorrelated surface topography, or a
self affine surface roughness. The existence of relaxation effects (that I
incorporate using a recently proposed model) produces the time increase of the
contact area towards an asymptotic value that can be much smaller than
the nominal contact area. For an uncorrelated surface topography, the time
evolution of is numerically found to be well fitted by expressions of
the form [, where the exponent depends on
the normal load as , with close to 0.5. In
particular, when the contact area is much lower than the nominal area I obtain
, i.e., a logarithmic time increase of the
contact area, in accordance with experimental observations. The logarithmic
increase for low loads is also obtained analytically in this case. For the more
realistic case of self affine surfaces, the results are qualitatively similar.Comment: 18 pages, 9 figure

Emerging dietary patterns: impact on child health
What we eat today and how we decide to produce sufficient food to meet both demand and nutritional requirements will determine the availability, diversity and quality of diets for future generations.
Acceptability and normalisation of new dietary patterns must be prioritised to the same extent as education on environmental sustainability and health, because these are important social levers. They can help to reduce the psychosocial barriers and anxieties often connected to the behaviour changes that are needed to transition away from the traditional Western eating habits that are now increasingly subject to critical scrutiny.
Without understanding the motivations and facilitators to change eating habits (and then designing and amplifying solutions which make those changes attractive and compelling in the modern world) positive changes to young people’s health and their environment through better food will not come quickly enough to halt potentially catastrophic consequences for people and planet.
Changing consumption is seen by experts as the most powerful lever compared to food waste reduction or more efficient food production methods and technological solutions. There is simply not enough on Earth to sustain the increase of intensification required to continue feeding a global population on its current trajectory with a diet so rich in animal produce.
However, radical behaviour modification is challenging and therefore cross-sector, bold and perhaps unorthodox leadership is necessary to inspire alteration in the food system, which will have a knock-on effect in terms of changing food environments and therefore food perceptions, narratives and behaviours.
There are no ‘quick fix’ solutions, but what is undeniable is that populations can only make effective shifts in dietary patterns if government and the food industry help them to make those changes. This requires budgetary investment in public health information and the implementation of policies that promote ways to eat healthily that are also affordable and environmentally sustainable. The aim is to offer food that tastes as good as it can be made to look so that uptake is maximised and the benefits are cumulative.
The inevitable upheaval incurred by making any alteration to entrenched patterns of consumption that have been centuries in the making should not be underestimated, but carrying on as before is no longer credible nor desirable. The aim is to offer ‘nutritious’ food.
