Bowtie Technique for Arthroscopic Hip Inversion Labral Repair

open access: yesArthroscopy Techniques, EarlyView.
Abstract Various suture techniques for arthroscopic hip labral repair have been described to address labral pathology. However, optimal restoration of the labral suction seal relies on proper tension and control of the labral tissue during the repair.

Numerical Research on Flow Characteristics at High Radii of Rim Seals with Different Geometric Structures

open access: yesEnergies
In the high-temperature mainstream of gas turbines, there is a rim clearance between the rotor and the stator. A rim seal is to prevent the intrusion of high-temperature gas by spraying cool fluid from the inside of the rim clearance to the outside.

Experimental Investigation of Burning Liquids in Reduced Oxygen

open access: yesFire and Materials, EarlyView.
ABSTRACT The effects of oxygen concentration on combustion of gases have been investigated on fundamental levels in several studies. However, the same type of fundamental studies has not been made for liquid or solid fuels due to complex relationships between flame structure and changing mass loss rates (MLR).

Coccolithophore particulate inorganic and organic carbon ratios: An evaluation of acid decalcification methods

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Accurate direct measurements of coccolithophore particulate inorganic and organic carbon ratios (PIC/POC) are crucial for understanding the physiology and role these microbes play in global ocean carbon flux. Direct measurements of POC are commonly obtained by acid fuming or applying acid directly to filters to dissolve PIC (CaCO3) prior to CN

Theoretical modelling of hot gas ingestion through turbine rim seals

open access: yesPropulsion and Power Research, 2012
The rim seals of gas turbines are used to prevent or reduce the ingestion of hot mainstream gas into the wheel-space between the turbine rotor and its adjacent stationary casing.

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

open access: yesPest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...
