Antibiofilm molecules active agains staphylococci / Molécules antibiofilm actives contre les staphylocoques (Nouveau)

Bacteria within biofilms can withstand the host immune responses, and they are significantly more tolerant to antibiotics and disinfectants. Our laboratory found that some coagulase-negative staphyloccal (CNS) isolates can efficiently block biofilm formation by other CNS species or Staphylococcus aureus. Hypothesis: Some CNS isolates produce antibiofilm molecules that can lead to the development of new […]

Simulation of electrocardiograms in a computer model of the heart and torso

Atrial fibrillation is the most frequent rhythm disorder in humans (nearly 250,000 patients in Canada). It often leads to severe complications such as heart failure and stroke. Diagnosis of this arrhythmia is mainly performed through the inspection of electrical signal recordings (electrograms and electrocardiograms). To develop and validate new diagnostic tools, it is necessary to […]

Development of Pickering water-in-oil-in-water double emulsion delivery system for protection of labile bioactive compounds

We recently showed that the fat crystal shells around water-in-oil (W/O) emulsion droplets could effectively screen the hydrophilic active components from the outer environment (Ghosh et al., Salt Release from Fat Crystal-Stabilized Water-in-Oil Emulsions. 103rd AOCS Annual Meeting, Long Beach, California, USA, May 2012). Formation of crystal shells around dispersed droplets in emulsion is a […]

The Political Economy of Public-Private Mixed Health Insurance

Developing countries, particularly the fast-growing BRIC countries, are increasingly switching their focus from economic development to social welfare, of which public health insurance is an important component. Currently, three major health care systems exist in OECD countries: National Health Service (NHS) in Nordic countries like Sweden and Norway and commonwealth countries including the United Kingdom, […]

Breast cancer detection using ultra-wideband technology

The project employs ultra-wideband (UWB) technology to construct an image of the breast in order to detect tumors. A mathematical model of the breast under UWB signal is built using human body properties and RF signals in the GHz range. The model is used to simulate the penetration and reflection of the UWB signals. From […]

Application of advanced oxidation and catalytic ozonation in removing antibiotics from water

The presence of emerging pollutants (chemicals such as pesticides, residual pharmaceuticals and personal care products) in surface water bodies is becoming a serious concern not only for their environmental impact, but also for their potentially serious adverse effects on human health. Antibiotics are important class of emerging pollutants in nature. Presence of antibiotics in nature […]

Application of solid catalysts to enhance degradation of emerging pollutants in water using ozone

The presence of emerging pollutants (chemicals such as pesticides, residual pharmaceuticals and personal care products) in surface water bodies is becoming a serious concern not only for their environmental impact, but also for their potentially serious adverse effects on human health. Innovative water treatment technologies are under investigation to determine their potential application in current […]

Development of a smartphone-based acoustic environment tracker for speech enhancement applications

Speech signals propagating in enclosed environments are distorted by two important, environment-related factors: a) the multiple reflections of the signal from the walls and other objects present in the room, which are called coloration and reverberation, for early and late reflections respectively, and b) competing acoustic signals coming from other sound sources than the speaker, […]

Advanced modulation formats and coherent detection in optical communications

Our research group examines techniques for mitigation of impairments in optical communications links and for increasing the capacity of those links. We address both optical and digital signal processing (DSP) solutions from a systems perspective. Maximizing the capacity of fiber communications is the rally cry for research in optical communi-cations this decade, with focus on […]

Seismic Behaviour of Multi-story Buildings with Asymmetric Setback

Building structures with asymmetric setbacks possess both vertical and in-plan irregularities. The former is due to the abrupt changes in the plan dimension at the level of the setback while the latter results from the asymmetry between the upper tower portion and the lower base portion. An asymmetric setback introduces mass, stiffness and resistance eccentricities […]
