Mosquito borne diseases in England:: past, present and future risks, with special reference to malaria in the Kent Marshes.

Malaria was once common in the marshes of southern England. In this study I investigated why a disease called benign tertian malaria became known as the killer of the marshes and looked at the present and future threat from malaria returning to these marshes. The main focus of research was carried out on the Isle of Sheppey, one of the last places in England to experience an epidemic of malaria. An historical analysis of malaria was carried out by analysing births and deaths using Parish and Hospital records. Here I make the case that the deaths associated with malaria were more likely to be caused by diarrhoeal diseases and acute respiratory infections. The present risk of malaria was assessed using several methods. Field surveys showed that populations of An. atroparvus on Sheppey were small and severely limited by the few over-wintering sites and the filamentous surface algae needed for the aquatic stages to develop. Local residents found mosquitoes a major nuisance during the summer months, but few of these were likely to be malaria vectors. Overall the risk of local malaria transmission is extremely low and far below that needed to maintain the disease. Searches of 52 aircraft arriving at Gatwick Airport from Africa revealed no malaria vectors suggesting that the risk of importing exotic mosquitoes by aircraft is remote. Finally, 1 developed a simple surveillance system that could be used for assessing the threat of future vector borne diseases, using West Nile virus as a model. Routine sampling with Mosquito Magnet traps, a carbon-dioxide baited trap, was extremely efficient at collecting large numbers of potential disease vectors and could be used as a tool for risk assessment programmes. These studies indicate that malaria is extremely unlikely to ever return to the United Kingdom

The chickpea book : a technical guide to chickpea production

The area of chickpea production in Australia has expanded rapidly in recent years especially in south-western Australia. This has been partly brought about by the keen interest of farmers and a concerted research effort and industry development by Agriculture Western Australia, The Centre for Legumes in Mediterranean Agriculture (CLIMA) and other institutions, in partnership with the Grains Research and Development Corporation and other industry funding bodies. Private consultants, grain traders and other industry groups have also contributed to the expansion of the industry. Much of the local knowledge generated by these research and development projects has been published in various experimental summaries, Tech notes, Farm notes, magazine articles, \u27On the Pulse\u27 newsletters, conference and workshop proceedings, and scientific papers. This book collates much of this research and development in the one document, together with experience and knowledge from the eastern states and overseas. It is a comprehensive publication, much more than simply how to grow the crop in Western Australia. It describes much of the scientific data behind our recommendations and highlights the role of chickpea production in maximising whole farm profits.https://researchlibrary.agric.wa.gov.au/bulletins/1212/thumbnail.jp

Ecological thresholds of the Chinese mystery snail (Cipangopaludina chinensis) in relation to Nova Scotia environments

1 online resource (48 pages) : illustrations (chiefly colour)Includes abstract and appendices.Includes bibliographical references (pages 42-46).The Chinese mystery snail, Cipangopaludina chinensis, is a non-indigenous, potentially invasive aquatic species found throughout North America. They are highly fecund and viviparous, birthing live young. These features make them a potential threat to biodiversity and ecosystem function. To better understand the potential spread of C. chinensis in Nova Scotia, the ecological thresholds for different environmental parameters need to be established. Here, I focused on salinity, pH, and temperature using field and laboratory approaches. The salinity tolerance [(0, 5, 10, 15, and 20) ppt], and pH tolerance (pH 4, 5, 6, 7) were tested in a 2-week and 4-week laboratory experiment, respectively. The migration patterns of C. chinensis were monitored bi-weekly at three Halifax Regional Municipality lakes with temperature measurements. Migration monitoring was done in spring and summer, conducting surveys of the relative frequency of snails found at various depths to estimate the seasonal migration pattern of the snails. C. chinensis did not survive in salinity concentrations 10 ppt or higher, but did survive in 0 ppt and 5 ppt. This suggests C. chinensis could inhabit freshwater to brackish water. There was some mortality with juvenile C. chinensis in low pH conditions, and further research is recommended to establish the pH threshold for at least one life cycle of the snails. The snail migration surveys show the snails are typically found in shallow water when the surface water temperature is 20⁰C and above, and in deeper water when the surface water temperature is 20⁰C and below. This research suggests the ecological tolerances of C. chinensis may allow for the species to spread into vulnerable ecosystems in Nova Scotia not previously considered as a suitable habitat, including brackish estuaries and acidic dystrophic lakes

Electronic/electric technology benefits study

The benefits and payoffs of advanced electronic/electric technologies were investigated for three types of aircraft. The technologies, evaluated in each of the three airplanes, included advanced flight controls, advanced secondary power, advanced avionic complements, new cockpit displays, and advanced air traffic control techniques. For the advanced flight controls, the near term considered relaxed static stability (RSS) with mechanical backup. The far term considered an advanced fly by wire system for a longitudinally unstable airplane. In the case of the secondary power systems, trades were made in two steps: in the near term, engine bleed was eliminated; in the far term bleed air, air plus hydraulics were eliminated. Using three commercial aircraft, in the 150, 350, and 700 passenger range, the technology value and pay-offs were quantified, with emphasis on the fiscal benefits. Weight reductions deriving from fuel saving and other system improvements were identified and the weight savings were cycled for their impact on TOGW (takeoff gross weight) and upon the performance of the airframes/engines. Maintenance, reliability, and logistic support were the other criteria
