In this work, the potential of auto-ignition of heavy oil during in-situ combustion (ISC) process was studied. Kinetic studies were carried out using Thermo Gravimetric Analyzer (TGA), Differential Scanning Calorimetry (DSC) and Accelerating Rate Calorimetric (ARC) techniques. Effects of oxygen partial pressure, reservoir pressure and clay on auto ignition condition were investigated on a n...

differential scanning calorimetry (dsc), temperature programmed desorption mass spectrometry (tpd-ms) and small angle neutron scattering (sans) were used to investigate co2 uptake by the wyodak coal. adsorption of carbon dioxide on wyodak coal was studied by dsc. the exotherms evident at low temperatures are associated with the uptake of co2 suggesting that carbon dioxide interacts strongly wit...

BACKGROUND AND PURPOSE Arterial spin labeling (ASL) is a perfusion imaging technique that does not require gadolinium. The study aimed to assess the reliability of ASL for evaluating reperfusion in acute ischemic stroke in comparison with dynamic susceptibility contrast (DSC) imaging. METHODS The study included 24 patients with acute ischemic stroke on admission and 24-hour follow-up ASL and ...

A carbon fiber/epoxy resin prepreg was tested by DSC, and the phenomenological nth-order autocatalytic reaction curing kinetic models of were established. On this basis, optimum process obtained. In addition, in order to explore effect ply parameters on mechanical properties laminates, thermomechanical laminates [0]10, [+ 45/ − 45]5s [0/90]5s, prepared compression molding, investigated. The res...

This study investigated the feasibility of using an electron beam (EB) process to cure chemically impregnated wood products. Maple wood planks were impregnated with the low-viscosity resins 1,6 hexanediol dimethacrylate (HDDA) and trimethylolpropane trimethacrylate (TMPTA). The addition of nanoparticles into the formulation was also studied. The impregnated wood was then cured by EB irradiation...

This paper reports the characterization of a photosensitive benzocyclobutene (BCB), a low dielectric constant spin-on polymer for use as interlayer dielectric in the microelectronics industry. Research work is divided into three main sections. First, BCB thin film characterization was done to investigate the effects of curing conditions on BCB film thickness, dielectric properties, optical prop...

Electrically conductive adhesives (ECA) are an alternative interconnection method for crystalline silicon solar cells, providing low thermomechanical stress, being lead-free and applicable to new contact structures. The ability to control their curing reaction in a stringing or lamination process is essential for enabling cost effective and reliable industrial module production. We set up an au...

the objective of this study was to formulate and evaluate the drug-polymer interaction of mefenamic acid (ma) using two polymers with different characteristics as ethylcellulose (ec) and/or cellulose acetate phthalate (cap). microspheres were prepared by the modified emulsion solvent evaporation (mese). the effect of drug-polymer interaction was studied for each of microspheres. important param...

Effects of pH and milk constituents (milk ultrafiltrate and ~:-casein) on denaturation of fl-lactoglobulin were investigated by a dynamic method based on differential scanning calorimetry. The apparent reaction order of /Ltactoglobulin denaturation by the dynamic method was 2.0 over the pH range of 4.0 to 9.0, which is in fair agreement with results by other investigators using more classical m...
