Gravimetric survey of Buried Bedrock Valleys

Project Description The objective of this project is to establish a baseline of water quality parameters within Rivers on the Yellow Dog Plains. An independent analytical laboratory and environmental consultants have prepared the work plan. Lab scientist will conduct the field sampling. All field and laboratory techniques will strictly follow US environmental Protection Agency (EPA) sampling and chain of custody protocols so that the data can be compared to other similarly collected data from past and future studies. The proposed work plan will provide information valuable in monitoring any changes in the water quality over the next few years from the rivers selected for testing. Fifteen locations of the water sampling are to be monitored on three river basins. Two sites on the Yellow Dog River will be monitored, eleven sites on the Salmon Trout River basin will be monitored and one site on the Cedar River basin will be monitored. Testing will be performed every month at various sites. The testing is outlined in Table 2. The locations will be documented using a hand-held GPS unit coordinates (decimal degrees). Water samples will be collected at sites for several water quality parameters listed in Table 3 & 4. Field measurements of pH, specific conductivity, dissolved oxygen (DO), and temperature will be measured at each site using calibrated field instruments. Each river will have at least one stream gauge and flow measurement following MDEQ protocol (GLEAS Procedure #77) at sampling sites

The impact of a workplace intervention on sitting time among office employees : standpoints!

Advisors: Josephine Umoren.Committee members: Priyanka Ghosh Roy; Lynn Herrmann.Includes bibliographical references.Includes illustrations.Excessive sitting time is a risk factor for type 2 diabetes, cardiovascular disease, metabolic syndrome, obesity, and premature mortality and is prevalent in office-based workplace settings. Researchers have designed a wide variety of interventions designed to increase physical activity in the workplace, but only within the last decade has decreasing sedentary activity explicitly been targeted. The objective of this pre/post quasi-experimental study (Standpoints!) was to evaluate the impact of a multi-component workplace intervention on office employees' percentage of sitting time. The 6-week intervention was comprised of web-based, in-person, and point tracker components. Changes in the percentage of sitting time at the workplace, in minutes per 8-hour work day (primary outcome), were measured by self-reported data through the Occupational Sitting and Physical Activity Questionnaire (OSPAQ). The control group was not exposed to this intervention; these participants were encouraged to continue normal daily routines and not to drastically change their nutrition habits or physical activity during the 6-week period. Relative to the controls, the intervention group significantly reduced workplace sitting time (mean change -45 min/8-h workday). Workplace sitting was replaced primarily by incorporating standing (+39 min 22 sec/8h workday) and walking (+5 min and 46 sec/8-h workday) with no change in heavy labor/physically demanding tasks. The control group alternatively had an increase in their percentage of sitting time during the span of the 6-week period (+8 min 38 sec/8h workday) and reduced the amount of standing (-6 min and 14 sec/8-h workday), walking (-4min and 19 sec/8-h workday), and heavy labor/physically demanding tasks (-58 sec/8h workday). This 6-week multi-component workplace intervention showed significant reductions in sitting time in the intervention group. Studies to assess the sustainability of this program and the potential for other health related benefits of reducing sitting time are needed.M.S. (Master of Science
