Thermo-activated drug release.
… fields can be adapted for use as a thermal-activated delivery system to achieve the desired dose and temporal control of drug release. To test this hypothesis, the following specific aims were carried out: (1) Determine the thermal response of superparamagnetic nanoparticles (SPNs) to …

Light-activated gene expression
A method for activating gene expression in cells by using photo-caged small molecules was developed. This method uses the Nuclear Hormone Receptor (NHR) family as a model system. This tool provided an opportunity to study the spatial and temporal control of genes by using small synthetic molecules …

Combat-Activated Thymic Disorientation
This thesis addresses the complexity of the experiences of severely distressed contemporary combat veterans in the Western world. It examines the specific features of their affliction that is not accounted adequately for either by the existing psychiatric approach to mental health disorders or by …

Aerobic digestion of waste activated sludge from biological nutrient removal activated sludge systems
Waste activated sludge (WAS) is a biological sludge that contains biodegradable and non-biodegradable volatile suspended solids (VSS) and non-volatile inorgainic suspended solids (ISS). Stabilization for safe disposal of the WAS is a process of paramount importance at wastewater treatment plants …

EXPERIMENTS WITH THE ACTIVATED PRESENCE
… research and artworks presented to audience. Activated presence refers to a way of researching, making and presenting performative artwork; artwork made from a place of attention to the moment. This is the expanded moment of Eastern philosophy, Christian mysticism and the new physics; what …

Phagosome proteomes in activated macrophages
… the phagosome functions regulated in activated macrophages and further exploring the mechanism by which alternative activation regulates phagosome biogenesis. First of all, a comparison of phagosome proteomes of BMDMs and RAW 264.7 cells was performed, suggesting that there are …

Characterisation of protease activated receptors
… transmembrane G-protein-coupled receptor that is activated by thrombin cleavage. In order to characterise the thrombin receptor three mouse monoclonal antibodies were isolated by using a recombinant fusion protein incorporating the extracellular domain of the human thrombin receptor as an antigen. …

Biological regeneration of activated carbon
… from an artificial wastewater in the absence of activated carbon. The data collected during this fermentation were logged on a PDP 11/40 minicomputer. Variables such as oxygen and carbon dioxide percent by volume evolved, the dissolved oxygen concentration, temperature, pH and volumetric air flow …

Laser Activated Bonding of Wood
It was found that laser modified wood surfaces can be bonded together to create a wood composite without the need of any additive. This bonding method removes the need of applying adhesive, potentially lowers cost, and eliminates off gassing of petroleum resins, creating a wood product with many …

Magnetically activated and guided isotope separation
… stable isotope enrichment called Magnetically Activated and Guided Isotope Separation (MAGIS) (1). Over the past century a large number of enriched isotopes have become available, thanks largely to electromagnetic separators called calutrons that were developed during World War II. These …

Activated Carbon from North Dakota Lignite
<p>Activated carbon was produced by reacting lignite char with steam in a fluidized-bed reactor which was designed and constructed for this study. Effects of three variables temperature, residence time and particle size, at four levels were studied statistically using a Latin square design. When …

Chemical modification of activated carbon adsorbents
Activated carbons have been modif fed using reactive chemicals to produce adsorbents of enhanced hydrophobic character which will also be resistant to surface oxidation that results from exposure to humid air ("ageing"). The intention was that modification would not disrupt the carbon pore …
-
Humic Substances Removal by Activated Carbon
… the removal of humic substances by various activated carbons. Different analytical methods were investigated to determine humic substances as possible indicators of chloroform formation potential. Total organic carbon measurement and ultraviolet/visible absorbance correlate well with the …
-
The contact stabilization activated sludge process
… and Marais put forward a general model for the activated sludge process based on an energy requirement for adsorption of the nutrient onto the organisms. They briefly outlined an alternative bi-substrate hypothesis in which the energy requirement for adsorption fell away. No evidence in support …
-
Kinetics of the activated sludge process
… the more important papers on the kinetics of the activated sludge process. These papers chronologically trace developments in the kinetic theory, from aerobic steady state behaviour to aerobic, nitrification and denitrification behaviour under cyclic flow and load conditions in multi-reactor …
-
Cations and activated sludge floc structure
… designed to investigate the effect of cations on activated sludge characteristics and also to determine their influence on digestion performance. For this purpose, cations in solution and in floc were evaluated along with various activated sludge characteristics and the collected waste activated …

Acclimation of activated sludge to pentachlorophenol
Bench scale activated sludge reactors were acclimated to dextrose and then to low levels of pentachlorophenol. The metabolic activity of activated sludge was evaluated by its specific rate of dextrose uptake, Δs/Δt/X (measured by COD removal). Depression of the specific uptake rate, resulting from …
