Characterization of a novel cellulose biosynthesis inhibitor, CBI28, in Gluconacetobacter xylinus
(2010-05-01)To study the underlying mechanisms for microbial cellulose biosythesis, a novel compound, CBI28, was used as an inhibitor along with classical genetics and EMS mutagenesis. An EZ-Link Biotin Hydrazide Kit was used to create ... -
Profile extrusion of wood plastic cellular composites and formulation evaluation using compression molding
(2010-05-01)Wood Plastic Composites (WPCs) have experienced a healthy growth during the last decade. However, improvement in properties is necessary to increase their utility for structural applications. The toughness of WPCs can be ... -
Energy use analysis and technology for electric transit buses
(2010-05-01)Electric vehicles offer a method of transportation where the energy generation process is moved from the on-board engine to the electrical generation system. The Canadian electrical generation mix has a significant portion ... -
Optimization algorithms in compressive sensing (CS) sparse magnetic resonance imaging (MRI)
(2010-06-01)Magnetic Resonance Imaging (MRI) is an essential instrument in clinical diag- nosis; however, it is burdened by a slow data acquisition process due to physical limitations. Compressive Sensing (CS) is a recently developed ... -
Effects of soy and milk ferments on measures of innate immunity: a comparison of effects in normal and microgravity conditions
(2010-07-01)Probiotics can influence intestinal responses and mucosal immunity either directly or indirectly through transient modulation of the endogenous microenvironment or the immune system. During space travel, astronauts experience ... -
Thermochemical energy storage systems: modelling, analysis and design
(2010-07-01)Thermal energy storage (TES) is an advanced technology for storing thermal energy that can mitigate environmental impacts and facilitate more efficient and clean energy systems. Thermochemical TES is an emerging method ... -
Three dimensional heterogeneous finite element method for static multi-group neutron diffusion
(2010-08-01)Because current full-core neutronic-calculations use two-group neutron diffusion and rely on homogenizing fuel assemblies, reconstructing pin powers from such a calculation is an elaborate and not very accurate process; ... -
Modeling of voltage source converter based HVDC transmission system in EMTP-RV
(2010-08-01)Voltage Source Converter (VSC) applications include but are not limited to HVDC, Flexible AC Transmission System (FACTS) devices such as STATCOM, SSSC, UPFC and Wind generators and active filters. The VSC based HVDC system ... -
Physical and chemical analysis of pig carcass decomposition in a fine sand
(2010-08-01)The development and improvement of methods used for the estimation of the postmortem interval (PMI) is a common area of research in forensic science. This research was conducted to physically and chemically analyze pig ... -
Molecular characterization of the binding site of nematode GABA-A receptors
(2010-08-01)Haemonchus contortus is a parasitic nematode that is controlled in large part by nematocidal drugs that target receptors of the parasitic nervous system. Hco-UNC-49 is a nematode GABA receptor that has a relatively low ... -
The Pharmacological Characterization of Hco-UNC-49, a GABA-gated Chloride Channel from the Parasitic Nematode Haemonchus contortus
(2010-08-01)Compared to mammals, nematodes appear to exhibit a unique GABAergic nervous system. Haemonchus controtus is a parasitic nematode that infects ruminants worldwide. Hco-UNC-49 is a H. contortus GABA-gated chloride channel ... -
A survey of algebraic algorithms in computerized tomography
(2010-08-01)X-ray computed tomography (CT) is a medical imaging framework. It takes measured projections of X-rays through two-dimensional cross-sections of an object from multiple angles and incorporates algorithms in building a ... -
Piezoelectric flexing and output voltage of a microchannel heat engine
(2010-08-01)In this thesis, a new model is formulated for a piezoelectric membrane and fluid motion in a microchannel heat engine. A new slug flow model is developed for droplet motion in a circular cross-section channel. The model ... -
Optomal three-time slot distributed beamforming for two-way relaying
(2010-08-01)In this study, we consider a relay network, with two transceivers and r relay nodes. We assume that each of relays and the two transceivers have a single antenna. For establishing the connection between these two transceivers, ... -
Integration of component-based frameworks with sensor modeling languages for the sensor web
