Setting sail for history

Setting sail for glucose homeostasis with the AKAP150-PP2B-anchor.

Glucose-stimulated insulin secretion, controlled by multiple protein phosphorylation events, is critical for the regulation of glucose homeostasis. Protein kinase A (PKA) is known to play a role in β cell physiology, but the role of its anchoring protein is not fully understood. Hinke et al (2012) illustrate the significance of A-kinase anchoring protein 150 in tethering protein phosphatase 2B ...

The Lateen Sail in World History

T the time of the Great European Excursion in the sixteenth century, the sail known as the lateen was in use in three different regions of the world. In the orthodox view, its existence and distribu-tion are a matter of importance for several reasons. First, sails as an artifact have not demonstrated very great human inventiveness, and since the lateen requires some ingenuity to conceive, its d...

History Matters: Setting the Scene

Starting to Sail

lent, considered by many to be one of the best sailing areas in the country, provided an opportunity not to be missed. Although my initial trip out was in a yacht, most of my early experience was in dinghies less expensive to buy and to repair if damaged. The first dinghy I shared was with three other equally inexperienced friends. We bought a 14 foot fibre glass family dinghy through Exchange ...

Flexible Models for Solar Sail Control

Solar sails employ a unique form of propulsion, gaining momentum from incident and reflected photons. However, the momentum transferred by an individual photon is extremely small. Consequently, a solar sail must have an extremely large surface area and also be extremely light. The flexibility of the sail then must be considered when designing or evaluating control laws. In this paper, solar sai...
