Herbal medicines are mainly used to maintain health, prevent diseases and treat chronic conditions. Although many Canadians have taken or are regularly take herbal products, there still are concerns about the safety and quality of these products. Osteoporosis is a chronic disease called silent thief since there are no symptoms until bone fractures happened. The fractures from osteoporosis are more common than heart attack, stroke and breast cancer combined. Especially for women approaching or being in menopause, lose 2-3% of their bone mass each year.
Sand production during extraction of bitumen in oil sand industry is the most significant challenge which results in many operational problems such as erosion of downhole and surface equipment, collapse of the formation, and subsequently a dramatic increase in capital and operating costs of the production plant. Mesh weaves are currently used to reject sand during production and mitigate these effects. The proposed research project will investigate the flow, and solid retention capacity of different mesh weaves in various test cells.
In this project, we develop a framework to use the data from fiber sensing technologies to smart monitoring of Oil and Gas Reservoirs. The project involves extensive lab experiments simulating different monitoring conditions. Different configurations for installation of sensing equipment will be examined. The optimum location of tubing will be also determined. Signal processing methods will be used to extract useful information from the raw fiber-sensed data. Through experiments, we will record and analyze the relationship of fiber-sensed signals and the flow conditions.
Automatic blood pressure monitors with inflatable cuff currently in use are inaccurate and produce inconsistent results. Even small movements during measurement can affect the measurement and lead to inaccurate diagnosis. This project aims to improve the accuracy of blood pressure monitors using advanced thin film sensors that can greatly improve the diagnosis. The project will enable a Canadian company to develop advanced technology that can put Canada as one of the hubs of blood pressure monitoring technology that only a few countries can boast of.
Dental caries affects the majority of the worlds population and causes tooth decay and loss. Bacteria in the mouth cause this disease. Sugar consumption plays a role in causing these bacteria to make acid that results in dental caries. Studies have shown that a type of sugar alcohol, called xylitol, can help prevent this disease. We will be studying the growth of oral bacteria that cause dental caries. We will examine this growth after applying an oral ultrasound gel (manufactured by SmileSonica Inc) that contains xylitol.
Sexual dysfunction is pervasive in our society and is associated with a blend of biological, psychological, relational and contextual risk factors. In this project we will apply machine learning algorithms on a set of known risk factors of sexual dysfunction to predict whether a new patient suffers from sexual dysfunction and whether sexual dysfunction will improve based on specific patient treatment plans.
Champion Pet Foods is a prominent pet food manufacturer in Canada. They manufacture high-end high quality dry pet food products. They are interested to use new processing technologies to eliminate the harmful bacteria from their products without damaging their quality. At University of Alberta, we are testing the effectiveness of new technologies such as atmospheric cold plasma to eliminate harmful bacteria from food products. As consumers do not like low quality foods, it is important to understand the quality changes in foods during processing of foods using new technologies.
The presence of harmful bacteria in drinking water sources can seriously harm the population that receives the contaminated water. The current standard methods for testing drinking water for bacteria heavily rely on using central laboratories. For small rural communities that are far from these laboratories, this scheme may represent 2-7 delays until they find out about the quality of their drinking water sources. This can be catastrophic if the residents of these communities drink contaminated water while waiting for the results.
This research aims at better understanding the performance of Wireline Applied Stimulation Pulse (WASP) technique in formation damage reduction in oil and gas wells. Hydrocarbon production rate decreases as a result of plugging the sand control devices located in the wellbore region. Shock waves generated by the WASP technique help breaking the sources of formation damage into smaller pieces; As a result, small particles can be carried to the surface.
Title: Design and development of a grating-based flow-cytometer
Flow cytometry is a technique used to detect and measure physical and chemical characteristics of a population of cells or particles. A sample containing cells or particles is suspended in a fluid and injected into the flow cytometer instrument. The sample is focused to ideally flow one cell at a time through a laser beam and the light scattered is characteristic to the cells and their components. Cells are often labeled with fluorescent markers so that light is first absorbed and then emitted in a band of wavelengths.
