The present paper addresses the high Reynolds number, two-dimensional, steady laminar flow separation phenomenon near an interior (concave) corner. A very fast Alternating Direction Implicit finite difference approach is used to solve the Interacting Boundary Layer approximation to the Navier Stokes equations in a conformal plane. Solutions are presented for corner angles up to 18° for Reynolds numbers (based on forebody length) up to 108. Convergence properties and accuracy levels are identified in order to provide reliability estimates of the results. Limitations to the numerical algorithm for large separation regions at high Reynolds numbers are identified.
Almost a millennium ago, a major upheaval occurred in Earth’s atmosphere: a giant cloud of sulphur-rich particles flowed throughout the stratosphere, turning skies dark for months or even years, before ultimately falling down to Earth.
We know this event happened because researchers have drilled and analysed ice cores — samples taken from deep within ice sheets or glaciers, which have trapped sulphur aerosols produced by volcanic eruptions reaching the stratosphere and settling back on the surface.
Ice can thus preserve evidence of volcanism over incredibly long timescales, but pinpointing the precise date of an event that shows up in the layers of an ice core is still tricky business.

Ira Pastor Comments:
So as frequent listeners of the ideaXme show know, we spend a lot of time talking about the theme of “healthy aging”, and the reality that aging, and related biological changes associated with aging, occur across all of the body’s cells, tissues, and organs, and these changes affect all structure and function of the body, including the teeth and gums, and as such, oral health is the focus of our show today.
The underlying processes of biological aging can dramatically affect oral health and many of the specific changes that occur over time in our bodies as we age (such as cells renewing at a slower rate, tissues become thinner and less elastic, bones become less dense and strong, our immune system become weaker, such that infection can occur more quickly and wound healing takes longer), can have major impact in the oral cavity (affecting tissue and bone in the mouth), as well as trickle down effects on the rest of the body.

You might’ve seen people on the internet saying “it’s like my autocomplete gets me.” Indeed, Keyboard protection AI has come a long way so much so that it can almost complete your sentences. So, why shouldn’t developers get the benefit of auto-complete too?
For years, IDEs (Integrated Development Environment) have tried to make development quicker by predicting the next part of a developer’s code. Now, startups like Codota are using AI to help developers with code completion on any code editor.
