BACKGROUND Given the technical difficulties, a limited number of works have been published on insular gliomas surgery and risk factors for tumor recurrence (TR) are poorly documented. OBJECTIVE The aim of the study was to determine TR in adult patients with initial diagnosis of insular Low-Grade Gliomas (LGGs) that subsequently underwent second surgery. METHODS A consecutive series of 53 pa...

The petroleum industry, through the production and consumption of oil gas, contributes to global greenhouse gas emissions. However, industry’s leadership experience in underground injection storage CO2, especially CO2 enhanced recovery (CO2-EOR), which has been proposed as a possible solution reducing atmospheric levels, not well acknowledged. Unlike traditional CO2-EOR, tends be net carbon emi...

Due to their environmentally friendly nature and high energy density, direct ethanol fuel cells have attracted extensive research attention in recent decades. However, the actual Faraday efficiency of oxidation reaction (EOR) is much lower than its theoretical value kinetics EOR sluggish due insufficient active sites on electrocatalyst surface. Pt/C recognized as one most promising electrocatal...

We present the LOFAR EoR Diagnostic Database (LEDDB) that is used in the storage, management, processing and analysis of the LOFAR EoR observations. It stores referencing information of the observations and diagnostic parameters extracted from their calibration. This stored data is used to ease the pipeline processing, monitor the performance of the telescope and visualize the diagnostic parame...

Underground injection of carbon dioxide for enhanced oil recovery (EOR) is a common practice in the oil and gas industry and has often been cited as a proven method of sequestering CO2 (US DOE, 1999). Of all sequestration methods, this is probably the best understood, as carbon dioxide has been used in the oil industry for many years. Additionally, most oil fields have been relatively well char...

Through iterative participatory design-based research I aim to explore the application of the Ecology of Resources (EoR) Framework (Luckin, 2008) to the design of technology enhanced contexts that scaffold learning and collaboration. Technology enhanced learning (TEL) contexts engage learners and the ecology of resources available to them as they move through time and space, in coordinated and ...

Pengrowth has targeted East Bodo (Alberta side) and Cosine (Saskatchewan side) for waterflood optimization and subsequent enhanced oil recovery applications. Currently, the most practical EOR technology for this heavy oil reservoir seems to be the polymer flood technology in combination with horizontal wells. Several investigators(1-4) have demonstrated the potential of the polymer flood techno...
