A remote sensing evaluation of potential for sinkhole occurrence

The relationship between lowering of the water table and sinkhole development in Pierson and in Hillsborough County, Florida was investigated. The locations of recently developed (1973) collapses were examined with respect to lineaments or fracture traces that are expressed in the terrain and visible in aerial photography and satellite imagery. It was anticipated that these relationships would provide the basis for establishment of criteria for mapping those land areas that have the greatest potential for sinkhole development. A very good correlation was found between mapped lineament intersections and known location of sinkhole occurrences for both study areas. This indicates that lineament and fracture trace mapping may be very useful in locating zones with the greatest potential for sinkhole development. It is further shown that this information is quite beneficial in land use planning applications

Can Brisbane remain a sub-tropical city?

As the seasons change, public and private gardens become a riot of colour. Winter shows the scarlet flags of poinsettia – Brisbane's emblem, which, if really a Mexican beauty, has made itself very much at home. The lavender glow of jacaranda and the gold of laburnum, the green umbrella of poinciana crowned with gleaming scarlet, the massed magnificence of magenta bougainvillea, the creamy blossoms and heavy tropical scent of frangipani filling the air with sweetness, the glare of cannas, the pink and white of bauhinia, the old-gold feathers of silky oak and the red and green of hibiscus – these are but a few of the array of colours.C. C. D. BrammallBrisbane has been relentlessly cleared since the first British soldiers and convicts set up at Redcliffe and then moved to the site we know as Brisbane today. As in other Australian colonies the new settlers were keen to grow crops and to exploit the timber both as a building material and later as a rich source of export income. While early explorers and botanists recorded the richness of the vegetation most new settlers saw the landscape as a resource to be exploited, not a pristine environment to be treated with respect.</jats:p

Climate change: impacts and threats on freshwater aquaculture

This paper examines the major effects of climate charge on aquaculture, especially on the freshwater ecosytem. Aquaculture as established is not practiced evenly across the world. Therefore, the paper highlights the current aquaculture practices within the regions and across the different environments to ascertain the major effects of climate variations on the freshwater ecosystem and aquaculture practices in particular. The main elements of climate change that would impact on aquaculture produ ction, such as sea level and temperature rise, changes in monsoon patterns and extreme climatic events and water stress, among others were properly looked at and the reasons for their effects addressed. The different elements of climate change that are experienced in varying degrees can be either positive or negative or directly or indirectly, depending on the different culture systems that are practiced. It is in the process of our study that we brought out the complex attributes of climate change as it affects aquaculture productivity and the possible roles that the society can play to ameliorate the harsh effects of this ugly monstet; referred to as &rdquo;climate change and the consequent global warming trends

Affordable measurement of core body temperature (T|) in a continuous, real-time fashion is now possible. With this advance comes a new data analysis paradigm for occupational epidemiology. We characterize issues arising after obtaining T| data over 188 workdays for 83 participating farmworkers, a population vulnerable to effects of rising temperatures due to climate change. We describe a novel approach to these data using smoothing and functional data analysis. This approach highlights different data aspects compared with describing T| at a single time point or summaries of the time course into an indicator function (e.g., did T| ever exceed 38 \ub0C, the threshold limit value for occupational heat exposure). Participants working in ferneries had significantly higher T| at some point during the workday compared with those working in nurseries, despite a shorter workday for fernery participants. Our results typify the challenges and opportunities in analyzing Big Data streams from real-time physiologic monitoring.R01 OH010657/OH/NIOSH CDC HHS/United StatesT32 NR012715/NR/NINR NIH HHS/United States2018-04-18T00:00:00Z27756853PMC57974917184vault:2081
