There are many reasons to preserve the biological diversity of the earth, and perhaps the most compelling is the insurance that it provides for the uncertain times ahead. The responsibility for maintaining this biodiversity falls particularly heavily on the custodians of the tropical forests, where species richness is highest. How can these forests provide for the immediate needs of local inhab...

This report presents results of an evaluation of the Strip Shopping Centre Program that commenced in 2003. It involved the treatment of eighteen strip shopping centres that were identified based on their poor crash history. The purpose of the study was to establish the effectiveness of the program in terms reductions in all types of casualty crashes and casualty crashes involving pedestrians th...

This article describes the sampling design, survey methodology and findings of a natural resources survey conducted in the Rathbun Lake Watershed in Southern Iowa in 1999-2000. The goal of the survey was to quantify the erosion from all sources on agricultural lands and the ecological health of streams for each of 61 subwatersheds in the area. A total of 183 plots of approximately 160 acres in ...

A study was undertaken to determine if meadow voles, Microtus pennsylvanicus, use habitats adjacent to apple orchards. Considerations were given to how extensively these areas were used, if at all, and if a bulldozed strip would control their movements between the orchard and adjacent border habitats. Trapping and telemetry data showed that meadow voles do use the adjacent border habitats exten...

The level of glucose in the blood can be measured by applying a drop of blood to a chemically treated, disposable ‘test-strip’, which is then inserted into an electronic blood glucose meter. The reaction between the test strip and the blood is detected by the meter and displayed in units of mg/dL or mmol/L. There are a number of different types of meters available, and all are slightly differen...

A robust classification algorithm that applies color science and image processing techniques is developed to automatically identify the pH level on a test strip. This algorithm is implemented on a camera phone that captures color images of pH test strips for healthcare or medical purpose. The pre-installed and platform independent program in the camera cell phone then processes the images capt...

Introduction The Potomac Formation is a heterogeneous assemblage of ancient river deposits consisting chiefly of unconsolidated and poorly consolidated sands, silts, clays, and small amounts of gravel, along with localized zones of diamictons of uncertain origin. It is the dominant geologic unit in the City of Alexandria. It crops out or is close to the surface everywhere west of Old Town and D...
