Honey production in Western Australia
the first ever survey of the potential production and value of apiary products from the south-west of Western Australia has shown beekeepers are collecting only 10 per cent of the potential honey crop.
The biggeest losses in honey production are caused by the enviroment, such as protracted drought, and extreme temperatures, heavy rain and cyclones during flowering. Fire, apiary sites leased but not used, and logging of forests also reduce the availability of apiary sites for honey production
Pollen from Western Australia at a glance
Western Australian pollen proteins are high compared to many other plant species. Banksia pollens are highest at greater than 30% followed by eucalypt and acacia, which range from 20-28%.https://researchlibrary.agric.wa.gov.au/bulletins/1093/thumbnail.jp
Surveillance of swarms and feral honey bees (Apis melliera) for the presence of American foulbrood (Paenibacillus larvae sub. sp. larvae) spores and their habitat preferences in Western Australia
Honey bees were first transported to Western Australia in 1841 (Barrett 1999) and in the years that followed the first feral honey bee swarms soon appeared in the Western Australian landscape. A brood disease of honey bees, American Foulbrood (AFB) became an economic nuisance in Western Australia by 1899 (Helms 1900) with whole apiaries being destroyed in some localities. It is now an endemic disease found in beekeeping operations world-wide.https://researchlibrary.agric.wa.gov.au/bulletins/1234/thumbnail.jp
Human Planetary Landing System (HPLS) Capability Roadmap: Wrap Up
When and how does the full scale system and subsystems need to be qualified & Human-rated for flight? Answer: No later than 29. Full scale AEDL Flight Tests can and should be done at Earth (need to get fast turn around between multiple tests). Do we need a Full Scale Validation Flight Test at Mars? Answer: Not, specifically, but the AEDL community is very uncomfortable with the notion of the very first full scale AEDL being piloted. The full scale unpiloted AEDL advance cargo mission that immediately precedes the human landing could do the trick. What kind of precursor AEDL Flight Tests are needed at Mars? Answer: We need to validate our performance & aerodynamic models by flying a scaled (1/10th?) version of the Full Scale Mission by 22. When and how do we decide on the AEDL system to fly? Answer: No later than 2015 (earlier is harder). We need to do multi-path full scale flight simulations and subscale / component development testing starting ASAP. If we find an AEDL for a landing mass of 40 MT, will this same architecture and technology paradigm extend to landing 80 MT? 120 MT? Is there another break point? Answer: We do not know yet
7.3 Communications and Navigation
This presentation gives an overview of the networks NASA currently uses to support space communications and navigation, and the requirements for supporting future deep space missions, including manned lunar and Mars missions. The presentation addresses the Space Network, Deep Space Network, and Ground Network, why new support systems are needed, and the potential for catastrophic failure of aging antennas. Space communications and navigation are considered during Aerocapture, Entry, Descent and Landing (AEDL) only in order to precisely position, track and interact with the spacecraft at its destination (moon, Mars and Earth return) arrival. The presentation recommends a combined optical/radio frequency strategy for deep space communications

A Macroscope for Global History. Seshat Global History Databank: a methodological overview
This is a pre-copyedited, author-produced PDF of an article accepted for publication in Digital Humanities Quarterly following peer review. The final published version is available online at: http://www.digitalhumanities.org/dhq/vol/10/4/000272/000272.html This work is licensed under a Creative Commons Attribution-Noncommercial-No Derivative Works 3.0 LicenseThis article introduces the ‘Seshat: Global History’ project, the methodology it is based upon and its potential as a tool for historians and other humanists. The article describes in detail how the Seshat methodology and platform can be used to tackle big questions that play out over long time scales whilst allowing users to drill down to the detail and place every single data point both in its historic and historiographical context. Seshat thus offers a platform underpinned by a rigorous methodology to actually do 'longue durée' history and the article argues for the need for humanists and social scientists to engage with data driven ‘longue durée' history. The article argues that Seshat offers a much needed infrastructure in which different skills sets and disciplines can come together to analyze the past using long timescales. In addition to highlighting the theoretical and methodological underpinnings, the potential of Seshat is demonstrated by showcasing three case studies. Each of these case studies is centred around a set of long standing questions and historiographical debates and it is argued that the introduction of a Seshat approach has the potential to radically alter our understanding of these questions.Peer reviewedFinal Accepted Versio
