Single plant selection for improving root rot disease (Phytophthora medicaginis) resistance in Chickpeas (Cicer arietinum L.)

The root rot caused by Phytophthora medicaginis is a major disease of chickpea in Australia. Grain yield loss of 50 to 70% due to the disease was noted in the farmers’ fields and in the experimental plots, respectively. To overcome the problem, resistant single plants were selected from the National Chickpea Multi Environment Trials (NCMET)—Stage 3 (S3) of NCMET-S1 to S3, which were conducted in an artificially infected phytophthora screening field nursery in the Hermitage Research Station, Queensland. The inheritance of resistance of these selected resistant single plants were tested in the next generation in three different trials, (1) at seedling stage in a shade house during the off-season, (2) as bulked single plants and (3) as individual single plants in the disease screening filed nursery during the next season. The results of the tests showed that many of the selected single plants had higher level of resistance and seed yield (P < 0.05) than the best resistant cultivars used as checks. The single plants with bidirectional expression of anthocyanin pigment, both at the shoot apex and at the base of stem, showed higher level of resistance than plants without it. The results also indicated certain level of heterozygosity-induced heterogeneity, which could cause higher levels of susceptibility, if the selected single plants were not screened further for the disease resistance in advanced generation/s. The genetics of resistance to PRR disease was confirmed as quantitative in nature

Range feeding of cotton by-products in the Kimberleys

Commercial cotton production has started in the Ord River area and by-products of the industry will soon be available for stock feeding in the surrounding pastoral areas. Cotton seed and cotton seed meal will cause digestive upsets if fed in any quantity to horses, poultry or pigs. Ruminants have no trouble in handling the material and the Kununurra ginnery could supply a useful protein supplement for Kimberley cattle

Scattering theory of walking droplets in the presence of obstacles

We aim to describe a droplet bouncing on a vibrating bath using a simple and highly versatile model inspired from quantum mechanics. Close to the Faraday instability, a long-lived surface wave is created at each bounce, which serves as a pilot wave for the droplet. This leads to so called walking droplets or walkers. Since the seminal experiment by {\it Couder et al} [Phys. Rev. Lett. {\bf 97}, 154101 (2006)] there have been many attempts to accurately reproduce the experimental results. We propose to describe the trajectories of a walker using a Green function approach. The Green function is related to the Helmholtz equation with Neumann boundary conditions on the obstacle(s) and outgoing boundary conditions at infinity. For a single-slit geometry our model is exactly solvable and reproduces some general features observed experimentally. It stands for a promising candidate to account for the presence of arbitrary boundaries in the walker's dynamics.Comment: 17 pages, 5 figure

China : its impact on the developing Asian economies

The rapid growth of East Asia, with China at its centre, has attracted global attention. Many authors have emphasised the emergence of regional production systems and the spread of high rates of growth across a large number of Asian economies. Nevertheless, the East Asian regional production system has not benefited all countries in the region equally. The more advanced Asian economies (Hong Kong, Singapore, South Korea and Taiwan) and the ASEAN-4 economies (Malaysia, Indonesia, Thailand and the Philippines) have a very different economic relationship in China compared with the poorer countries of the Greater Mekong Subregion (Cambodia, Laos, Myanmar and Vietnam). While the former have benefited from complementarities with China, supplying parts and components to largely export-oriented assembly plants, the latter are selling raw materials and resource-based products to China. China’s growth offers many opportunities for other Asian countries to accelerate their growth. Making use of these opportunities for purposes of income generation of poor people requires prioritising two policy areas. The first is connectivity. Some parts of Asia remain poorly connected to this regional production system. Better infrastructure and better trade links are key to enhancing the growth and incomes in these parts of Asia. The second priority is enhancing sustainability. The poorer Asian countries have increased exports to China, but much of this resource-based export growth is unsustainable. Sustaining and increasing trade between China and these countries has the potential to be more effective than increasing aid for the pursuit of poverty reduction and improved welfare in the poorer countries of the region. However, these countries will only benefit from the dynamism of the East Asian regional economy if policy initiatives directly address the issue of sustainability of resource extraction. These initiatives need to be taken not only in the exporting countries, but also in China itself. Keywords: regional integration; value chains; East Asia; economic development

Implementation of the Elementary Classroom Computer Initiative: A Description of the First Year

This report was commissioned by Henrico County Public Schools to evaluate the first implementation of its elementary classroom computer initiative. It describes the first year of the initiative and is the first formative evaluation report. The complete evaluation project will span five years. This report is descriptive only, however, subsequent reports will be more inferential in nature, e.g., examining the impact of the initiative on student performance. This report focuses on how the implementation has been perceived by teachers, students, and school division personnel. The primary focus was on teacher perceptions of the implementation phase of the initiative. The study involved surveying teachers and interviewing division personnel. Several focus groups were conducted as well and some of the comments support findings discussed in this report. Additionally, recommendations are presented to optimize the effectiveness of the initiative as well as assist the division in future implementations

The structural geology of the Naukluft Nappe Complex and its relationship to the Damara Orogenic Belt, South West Africa/Namibia

The Naukluft nappe complex has been quoted as a classic example of gravity gliding tectonics (Korn & Martin, 1959). Situated close to the southern margin of the Damara orogenic belt, it provides a key to the persistent controversy over the correlation of the "geosynclinal" Damara Supergroup with the Nama Group on the Kalahari craton. It also contains critical evidence bearing on the timing and large-scale geodynamics of the Late Precambrian-Early Palaeozoic Damara orogeny, particularly the hypothesis that it involved plate tectonic processes of subduction and continental collision in the southern zones
