Contributions of Limb Joints to Energy Absorption during Landing in Cats

GwynneL.

Contributions of Limb Joints to Energy Absorption during Landing in Cats SUMMARY: How is it that cats are able to jump down from high places and not hurt themselves? Researchers in this study observed 5 cats, jumping from various heights, for clues as to what sorts of forces and shock absorbers were at work. The… Continue reading Contributions of Limb Joints to Energy Absorption during Landing in Cats

The meaning of blood pressure

GwynneL.

The meaning of blood pressure SUMMARY: This article talks about all the physical aspects of blood pressure. The first few sections talks about the 3 forces that affect blood pressure: elastic, kinetic, and gravitational. The author also talks about how kinetic energy can be converted to elastic energy in the case of an aneurysm in… Continue reading The meaning of blood pressure

Using Pu in a molten salt fast reactor

GwynneL.

A disruptive approach to eliminating weapon-grade plutonium – Pu burning in a molten salt fast reactor SUMMARY: This study looked at the efficiency of several types of nuclear reactions: molten-salt reactors, light water reactors, and fast reactors. Using a program (written in Python), scientists looked at the data from each type of reactors and compared… Continue reading Using Pu in a molten salt fast reactor
