Challenging Resection Comes in Many Forms: Addressing Difficult Cam Morphology

open access: yesArthroscopy Techniques, EarlyView.
Abstract Femoroacetabular impingement with cam morphology that fails nonoperative management can be addressed with hip arthroscopy and cam resection. There exists a wide variation of cam morphology due to various etiologies that can make some cam lesions more challenging to address. A thorough preoperative evaluation and the utilization of a variety of

Lateral Ulnar Collateral Ligament Reconstruction Through a Mini‐Invasive Approach

open access: yesArthroscopy Techniques, EarlyView.
Abstract Posterolateral rotatory instability is the most common form of elbow instability, secondary to valgus, supination, and axial loading in elbow extension. The lateral ulnar collateral ligament (LUCL) is the primary restraint to posterolateral rotatory instability and multiple techniques of repair and reconstruction of the LUCL have been reported

Avoiding Femoral Tunnel Convergence and Graft Damage While Performing Anterior Cruciate Ligament Reconstruction With Lateral Extra‐articular Tenodesis

open access: yesArthroscopy Techniques, EarlyView.
Abstract Lateral extra‐articular tenodesis (LET) procedures have become increasingly popular in recent years as adjuncts to anterior cruciate ligament (ACL) reconstruction. One potential complication of combining LET with ACL reconstruction is tunnel convergence, which can lead to inadvertent loss of femoral ACL graft fixation.

A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.

Optimisation of vertical axis wind turbines

open access: yes
A practical Vertical Axis Wind Turbine (VAWTs) based on a Darrieus rotor has been designed and tested and found to be capable of self-starting at wind speeds above 4m/s. The self-start feature has been achieved by replacing the usual symmetrical aerofoil

The Use of Renewable Energy in Prominent City Buildings: A Diffusion Study on Top European Football Organizations

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The present study applied the diffusion of innovation theory to investigate the rate of diffusion of renewable energy sources used by Europe's top professional football stadiums and the relationship with carbon neutrality. A discrete diffusion model estimated the diffusion of renewable energy to saturation, and a multivariate logistic ...
