BACKGROUND AND PURPOSE Aneurysm embolization is not without risk: numerous technical aspects are considered before, during, and after the procedure. The purpose of this study was to show the position of the detachment zone of a Guglielmi detachable coil (GDC) with respect to the catheter tip for various microcatheters and marker alignments. METHODS Six types of commonly used microcatheters we...

ZSM-5-containing catalytic additives are widely used in oil refineries to boost light olefin production and improve gasoline octanes in the Fluid Catalytic Cracking (FCC) process. Under the hydrothermal conditions present in the FCC regenerator (typically >700 °C and >8% steam), FCC catalysts and additives are subject to deactivation. Zeolites (e.g., Rare Earth USY in the base catalyst and ZSM-...

Commercial shipping cannot readily reduce its dependency on fossil fuels. Ships are large energy consumers and need to carry sufficient fuel for a voyage. The principle of green steaming, when ships travel at slower speeds to arrive just-in-time, is discussed and a methodology developed to estimate the carbon savings resulting if the industry were to adopt this practice. The method is based on ...

Sea lettuce (Ulva rigida) is an underutilized green macroalga. Scant knowledge and understanding exist regarding the optimal processing technologies to maximize seaweed nutrition. Pretreatment of sea before drying, either by blanching or steaming, induced diverse physical biological property changes. Greenness increased, while lightness the-sea reduced. Both drying processes reduced textural pa...

Turkey oak lumber is difficult to dry, being prone cracks even at low temperatures. The main objective of the research was test different drying conditions in order establish whether air-drying or kiln-drying from a green state more suitable; if width had an influence on quality; prior steaming positive effect upon time and end could be avoided by protecting board ends; what most appropriate we...
