Development of paper-based analytical devices for particulate metals in welding fume
Includes bibliographical references.2015 Fall.Exposure to metal-containing particulate matter places a tremendous burden on human health. Studies show that exposures lead to cardiovascular disease, asthma, flu-like illnesses, other respiratory disorders, and to increased morbidity. Individuals who work in occupations such as metalworking, construction, transportation, and mining are especially susceptible to unsafe exposures because of their proximity to the source of particle generation. Despite the risk to worker health, relatively few are routinely monitored for their exposure due to the time-intensive and cost-prohibitive analytical methods currently employed. The current paradigm for chemical speciation of workplace pollution is outdated and inefficient. Paper-based microfluidic devices, a new type of sensor technology, are poised to overcome issues associated with chemical analysis of particulate matter, specifically the cost and timeliness of exposure assessment. Paper sensors are designed to manipulate microliter liquid volumes and because flow is passively driven by capillary action, analysis costs are very low. The objective of this work was to develop new technology for rapidly measuring Ni, Cu, Fe, and Cr in welding fume using easy-to-use paper devices. This dissertation covers the development of two techniques for quantifying metal concentration: spot integration and distance-based detection. Metal concentrations as low as 0.02 ppm are reported. A method for controlling reagent deposition as well as a new interface for multiplexed detection of metals, is discussed
Ultrasound in Rheumatology
__Abstract__
Ultrasonography is an imaging modality that is used increasingly in daily practice
for the investigation and management of rheumatoid arthritis (RA). This introduction
provides an overview on the rationale for using US in RA by discussing relevant
events and developments in the history of RA. This is followed by a short section
on the history of medical US. Subsequently, the section on the technique of US will
describe relevant concepts of US for this thesis. This general introduction closes with
the outline of the thesis and the aims
Fattening foods - perceptions and misconceptions: a qualitative and quantitative exploration
Describes adults\u27 perceptions and beliefs about foods that are considered "fattening". Use of qualitative and quantitative methods to determine the prevalence of the perceptions among adults; Range of factors that are considered when judging foods as "fattening"; Limitations in the public\u27s understandings of "fattening foods" which are inconsistent with dietary recommendations.<br /
Minnesota Native American Leadership Alumni Network Project 2011-2016
In 2011, representatives from Native Americans in Philanthropy (NAP) and the Tiwahe, Blandin, Bush, Northwest Area and Headwaters Foundations formed the Native American Leadership Collaboration to learn together about the work each was doing to support American Indian leadership development.This report discusses its process to advance a collective leadership movement in Native communities
