Trent University is a liberal arts and science-oriented institution located along the Otonabee River in Peterborough and Durham, Ontario, Canada.The enabling legislation is the Trent University Act, 1962-63. The university was founded through the efforts of a citizens' committee interested in creating a university to serve the Trent valley. The chancellor of Trent University is Don Tapscott, and Dr. Leo Groarke is the president and vice-chancellor.The Symons campus of Trent is approximately 5.6 km2 , over half of which is a part of Trent's Nature Areas, an ecologically diverse wild-life preserve. It is divided into a series of colleges: Champlain, Lady Eaton, Catharine Parr Traill, Otonabee, Peter Gzowski, and Julian Blackburn. Each college has its own residence hall, dining room, and student government, other than Julian Blackburn which is a non-residential college and home to Trent's 1,700 part-time students. The campus plan and the original college buildings were designed by the Canadian architect Ron Thom. A large portion of the main campus consists of land that was donated by General Electric Canada. This donation included a functioning hydroelectric power plant dating from the 1890s, which still generates a substantial portion of the university's electricity; the power plant is being updated and a second generating plant being considered.Trent also runs a full- and part-time program in Durham at the Thornton Road campus, with an enrolment of over 800 students. The university is represented in Canadian Interuniversity Sport by the Trent Excalibur. Some of the specialized programs at Trent include the Queen's University/Trent concurrent education program, the Trent University School of Education, a joint program with Fleming College allowing students to earn a B.Sc.F.S. in Forensic Science, and a B.Sc.N. program in Nursing.

Electrochemistry was one of the first sciences to benefit from the fractional calculus. Electrodes may be thought of as "transducers" of chemical fluxes into electricity. In a typical electrochemical cell, chemical species, such as ions or dissolved molecules, move towards the electrodes by diffusion. Likewise, other species are liberated into solution by the electrode reaction and diffuse away from the electrode into the bulk solution. It is demonstrated in this paper that the electric current is linearly related to the temporal semiderivative of the concentrations, at the electrode, of the species involved in the electrochemical reaction. More usefully, the semiintegral of the current provides immediate access information about concentrations. © 2009 Civil-Comp. Ltd and Elsevier Ltd. Source

While historically sex has been seen primarily as the prerogative of the young, more recently, the emphasis has been on the maintenance of active sexuality as a marker of successful ageing. A new cultural consensus appears to have emerged which not only emphasises the importance of continued sexual activity across the lifespan, but links sexual function with overall health and encourages increased self-surveillance of, and medical attention to, late-life sexuality. Drawing on historical accounts, clinical research, popular science reporting and health promotion literatures, I explore several key shifts in models of sexual ageing, culminating in the contemporary model of gender, sexuality and ageing that has made ageing populations a key market for biotechnologies aimed at enhancing sexual function. Two central concepts frame my analysis: 'virility surveillance', where age-related changes in sexual function are taken as indicative of decline, and the 'pharmaceutical imagination', where sexual lifecourses are reconstructed as drug effects revise standards of sexual function. After consideration of how narratives emerging from qualitative research with older adults challenge the narrow depiction of sexual functionality promoted by pharmaculture, conclusions call for continued critical inquiry into the biomedical construction of sex and age. © 2010 The Author.

Increased attention is being paid to the role of reforestation in strategies for sustainable forest management, landscape restoration and carbon sequestration. Reforestation of drainage basins is generally assumed to reduce annual streamflow as well as peak and low flows. However, most studies of reforestation effects on streamflow have been conducted on small experimental basins, and the applicability of their results to larger basins is unclear. This study revisits an earlier examination of streamflow response to headwater reforestation in a 267 km 2 basin (Ganaraska River) in southern Ontario, Canada for 1945-2007. Forest cover in the basin headwaters increased from 13 km 2 in 1945 to 31 km 2 by 1990, with most of this change between 1950 and 1965. Streamflow metrics from the reforested basin and two headwater sub-basins were compared to those from a nearby basin and sub-basin of similar size and physiography to the Ganaraska basins but without extensive headwater reforestation. No temporal trends were found for inter-basin differences in annual runoff or runoff ratios for the entire Ganaraska basin or its largest sub-basin; however, reforestation appears to have reduced several metrics of peak streamflow at the basin and sub-basin scale. Relationships between high flows classified according to generating event type and the associated precipitation depth suggest that expansion of forest cover in the Ganaraska River basin (GRB) and associated changes in microclimatic conditions have reduced the potential for frozen soil to generate surface runoff and high flows in response to rain-on-snow during spring snowmelt. This was accompanied by increased low flows from the GRB and its sub-basins from 1960 to 2007 relative to the control basin, suggesting that the expanded forest cover has enhanced groundwater recharge by prolonging spring snowmelt and promoting infiltration of rainfall and snowmelt inputs relative to non-forested areas. Some discrepancies between these results and those of other studies of streamflow response to reforestation may be attributed to the relatively large size of the GRB and the limited extent of reforestation. Nevertheless, the results highlight the importance of considering how reforestation may affect key hydrologic processes in a given landscape when predicting the resulting streamflow response. © 2011 John Wiley & Sons, Ltd.

In glacier-fed systems climate change may have various effects over a range of time scales, including increasing river discharge, flood frequency and magnitude. This study uses a combination of empirical monitoring and modelling to project the impacts of climate change on the glacial-fed Middle Fork Toklat River, Denali National Park, Alaska. We use a regional calibration of the model HBV to account for a paucity of long term observed flow data, validating a local application using glacial mass balance data and summer flow records. Two Global Climate Models (HADCM3 and CGCM2) and two IPCC scenarios (A2 and B2) are used to ascertain potential changes in meteorological conditions, river discharge, flood frequency and flood magnitude. Using remote sensing methods this study refines existing estimates of glacial recession rates, finding that since 2000, rates have increased from 24 m per year to 68.5m per year, with associated increases in ablation zone ice loss. GCM projections indicate that over the 21(st) century these rates will increase still further, most extensively under the CGCM2 model, and A2 scenarios. Due to greater winter precipitation and ice and snow accumulation, glaciers release increasing meltwater quantities throughout the 21(st) century. Despite increases in glacial melt, results indicate that it is predominantly precipitation that affects river discharge. Three of the four IPCC scenarios project increases in flood frequency and magnitude, events which were primarily associated with changing precipitation patterns, rather than extreme temperature increases or meltwater release. Results suggest that although increasing temperatures will significantly increase glacial melt and winter baseflow, meltwater alone does not pose a significant flood hazard to the Toklat River catchment. Projected changes in precipitation are the primary concern, both through changing snow volumes available for melt, and more directly through increasing catchment runoff. Source

This article analytically contextualises the spate of contemporary land deals popularly known as "land grabbing' by locating such deals within the processes that simultaneously underpin the capitalist restructuring of global agriculture and deepen the global subsistence crisis. The article situates contemporary land deals within the context of recent rises in food prices, offers a precise definition of land grabbing and reviews the global public policy response. It then offers an agrarian political economy analysis of contemporary corporate farmland acquisition and argues that land grabbing facilitates a broadening and a deepening of industrialised capitalist agriculture as a process of "intensification" is " 'extensified" on a world scale. This is done in order to sustain the cheap food necessary for capital accumulation. It is suggested that this will not solve the biophysical and social contradictions of industrialised capitalist agriculture and the food-based social exclusion which plagues the globe. © 2012 Canadian Association for the Study of International Development (CASID).
