A Field Primer for Monitoring Benthic Ecosystems Using Structure-From-Motion Photogrammetry

Abstract:
In 2019, The Hastings Center will celebrate its fiftieth anniversary. It is more than a bit staggering to think how far we have come since 1969. When I floated the idea of a center on bioethics to my friend and neighbor, psychiatrist Willard Gaylin, at a Christmas party in 1968-even before the word "bioethics" was used-I had only the fuzziest idea of where that would take us. Neither Will nor I had run anything, nor did we know how to raise money to support an organization. We would and did learn how, but much of what we did in those early years was made up on the fly. We not only had to invent an organization but no less to invent a field of research and education on issues still little noticed by the public or academics. Out of curiosity, I recently googled "bioethics." I was astonished at what I found and by the sheer quantity of what is going on.

Steps in the Modeling Process
Attention is the first necessary component for observational learning. It involves focusing on what the model is doing and saying. For example, if you decide to take a drawing class to enhance your skills, you need to pay close attention to the instructor's words and hand movements. The characteristics of the model significantly...
Pumped Concrete
For direct-acting pumps, the concrete enters the pump via the inlet valve under the action of gravity and suction created by the movement of the piston. This concrete is then forced into the pipeline and out through the outlet valve by the forward movement...
