Fluid Dynamic Behaviour of Conventional and Pressure Relieving Brush Seals
Joshua P. Bowen, Joshua J. Bird, Harry Cross, Matthew R. Jenkins, Aaron A. Bowsher, Peter F. Crudgington, Carl M. Sangan, James A. Scobie
Jun 30, 2024
Brush seals consist of a static ring of densely packed, flexible, fine wire bristles that provide resistance to the flow. Pressure relieving brush seals can be employed to overcome issues such as hysteresis that affect seal...
Structure and function of respiratory turbinates in phocid seals
Abstract: In terrestrial mammals, the respiratory turbinate bones within the nasal cavity are employed to conserve heat and water. In order to investigate whether environmental temperature affects respiratory turbinate structure...
ArcHives—combined palynological, genomic and lipid analysis of medieval wax seals
Abstract Beeswax is a product of honeybees (Apis mellifera ) and has been used extensively through time, especially as the primary component in medieval sealing wax for...

Mitochondria-targeted antioxidant therapy with MitoQ ameliorates aortic stiffening in old mice.
Rachel A Gioscia-Ryan, Micah L Battson, Lauren M Cuevas, Jason S Eng, Michael P Murphy, Douglas R Seals
Jun 18, 2018
Aortic stiffening is a major independent risk factor for cardiovascular diseases, cognitive dysfunction, and other chronic disorders of aging. Mitochondria-derived reactive oxygen species are a key source of arterial oxidative...
Influence of Flow Coefficient on Ingress Through Turbine Rim Seals
Rim seals are critical in terms of limiting the temperature of highly-stressed engine components but function with a penalty to the power output and contribute to entropy gain stemming from mixing losses in the turbine. Ingress...

Steady computations of ingress through gas turbine rim seals
In gas turbines, rim seals are fitted at the periphery of the wheel-space between the turbine disc and its adjacent casing; their purpose is to reduce the ingress of hot mainstream gases. This paper describes the use of a...

BACKGROUND: Although the use of clustering methods has rapidly become one of the standard computational approaches in the literature of microarray gene expression data analysis, little attention has been paid to uncertainty in...
Experimental and Computational Investigation of Flow Instabilities in Turbine Rim Seals
Josh Horwood, Fabian Patricio Hualca Tigsilema, James Scobie, Mike Wilson, Carl Sangan, Gary Lock
Jan 01, 2019
In high-pressure turbines, cool air is purged through rim seals at the periphery of wheel-spaces between the stator and rotor disks. The purge suppresses the ingress of hot gas from the annulus but superfluous use is...

Flow Instabilities in Gas Turbine Chute Seals
Joshua Horwood, Fabian Patricio Hualca Tigsilema, Michael Wilson, James Scobie, Carl Sangan, Gary Lock, Johan Dahlqvist, Jens Fridh
Feb 29, 2020
The ingress of hot annulus gas into stator-rotor cavities is an important topic to engine designers. Rim-seals reduce the pressurised purge required to protect highly-stressed components. This paper describes an experimental and...
The Expansion of Approximant /r/ in Dutch
Renée Van Bezooijen
Sep 30, 2014
In present-day Standard Dutch as spoken in the Netherlands, three main categories of pronunciation variants of Irl can be distinguished, namely alveolar /r/, uvular /r/, and approximant /r/. Approximant /r/, the focus of this...

Do Pinnipeds Have Personality? Broad Dimensions and Contextual Consistency of Behavior in Harbor Seals (Phoca vitulina) and California Sea Lions (Zalophus californianus)
Personality has now been studied in species as diverse as chimpanzees and cuttlefish, but marine mammals remain vastly underrepresented in this area. A broad range of traits have been assessed only once in each of bottlenose...
