Air Corridors: Concept, Design, Simulation, and Rules of Engagement.

Air corridors are an integral part of the advanced air mobility infrastructure. They are the virtual highways in the sky for the transportation of people and cargo in a controlled airspace at an altitude of around 1000 ft. to 2000 ft.

Surveillance of testicular microlithiasis? Results of an UK based national questionnaire survey.

Background: The association of testicular microlithiasis with testicular tumour and the need for follow-up remain largely unclear.

Methods: We conducted a national questionnaire survey involving consultant BAUS members (BAUS is the official national organisation (like the AUA in USA) of the practising urologists in the UK and Ireland), to provide a snapshot of current attitudes towards investigation and surveillance of patients with testicular microlithiasis.

Results: Of the 464 questionnaires sent to the BAUS membership, 263(57%) were returned.
