In 2003, the Institute of Nutrition and Food Technology (INTA) of the Universidad de Chile led a series of experiments geared towards proving that copper did indeed give an antimicrobial added value. These studies followed 2 protocols, as follows: |

MODELING A HORSE’S GAIT

There are three different states or forms of support currently recognized for when a horse is in motion; these are the step, trot and canter. Each is distinguished by the number of limbs that are in contact with the ground at a given time and the duration of suspension in the air. In a walk for example, at least one limb is raised with the other three supporting and therefore no time is spent suspended. The trot on the other hand is composed two legs supporting the horse in diagonal pairs, with a brief drop and rise when alternating pairs. Finally, a gallop is distinguished by containing a suspension phase during which all four limbs are off of the ground. This basic observation with regards to a limbs contact with the ground has given rise to a mathematical model that seeks to quantify the effects caused by a horseshoe within the complex system of a horse’s gait. The model presented simply involved mechanical factors such as weight, impact strength, position, speed, and acceleration; this means other factors were not considered such as race, specialty, and age. The whole problem has been condensed into the kinetic interaction of related bodies somehow representing the horse as a whole. |
