Chemical cautery of the inferior turbinates with trichloroacetic acid

open access: yesInternational Archives of Otorhinolaryngology, 2011
Introduction: Chronic secondary nasal obstruction, the hypertrophy of the inferior turbinates is a common symptom of great morbidity in our society. Several surgical techniques are described to cases refractory to medical treatments, however, there are ...

Durene conversion in a methanol‐to‐jet process: Exploring conversion at 150–350°C over different acid catalysts

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.

Production of middle distillates through olefin oligomerization using ZSM‐5 as a catalyst

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The global transportation sector relies heavily on gasoline (C5–C12) and diesel (C11–C24), which together account for approximately 60% of its energy needs. Driven by rapid industrialization and urbanization, diesel consumption is outpacing gasoline, with projections estimating global demand by 2035 at 27 million barrels per day for gasoline ...

Form and load transfer aspects of foundation systems: Case‐based implementation and adaptation for buildings

open access: yesDeep Underground Science and Engineering, EarlyView.
Upon conceptualization of structural behavior, foundations in terms of their form are divided into linear (1D), planar (2D), and volumetric (3D). Regarding the load transfer mechanisms, linear foundation systems are considered vector‐acting, planar foundations are divided into section and surface‐acting, and volumetric ones are recognized as block ...
