A New View of Pterosaur Feeding Habits

1633 Few things capture a child’s imagination like the age of dinosaurs, and it’s no wonder. The dinosaur seems an improbable beast, yet the fossil record tells us that vegetarian sauropods longer than a football fi eld once lumbered alongside tractor-trailer–sized predatory carnosaurs. Above these behemoths soared the reptilian pterosaurs, some propelled by wings spanning more than 12 meters. ...

Development of a Design Procedure for Aeronautical Structures Based on Reliability

In this paper, an approach to aeronautical structural design based on reliability analysis is presented. In this way, the concept of level of safety is discussed and methods of its calculation using statistical data are described. Based on the concept of level of safety, a design procedure is proposed. In order to validate this design procedure, two design cases are studied. In the first case s...

Epidemiology of Inflight Medical Events

Introduction: Since the 1950s, air travel has grown exponentially. In 2018, the number of international air passengers was estimated at 4.1 billion. Air travel exposes the passenger to a number of constraints (like physical constraints, stress) that can be correlated and lead to an inflight medical event, especially for passengers with chronic conditions or fragile health.<br /...
