MICROWAVE OVENS: AN INTRODUCTION
Microwave ovens have infiltrated our lives to such an extent that life without them has become impossible. The ability of a microwave oven to quickly and safely cook food appeals to all of us. But how safe is it? This series of articles will study and analyze the microwave oven and its working in detail and try to give you an orientation as to what that little box on your kitchen counter really is. The first article is about the origins of the microwave oven and its components.

Livestock Comfort
It is spring (soon to be summer) here in British Columbia, and with the sunny season comes warmth. But while it is pleasant outside now it can also become unbearably hot. The heat of summer or lack of it during winter can dramatically affect the productivity of your livestock operation. It is for this reason I thought this month I would explore the role of temperature plans when it comes to livestock farming.

The Insanity of the Defense
A person is held not responsible for his criminal actions if s/he cannot tell right from wrong ("lacks substantial capacity either to appreciate the criminality (wrongfulness) of his conduct" - diminished capacity), did not intend to act the way he did (absent "mens rea") and/or could not control his behavior ("irresistible impulse"). These handicaps are often associated with "mental disease or defect" or "mental retardation".
