Integrated Concepts One long straight wire is to be held directly above another by repulsion between their currents. The lower wire carries 100 A and the wire 7.50 cm above it is 10-gauge (2.588 mm diameter) copper wire. (a) What current must flow in the upper wire, neglecting the Earths field? (b) What is the smallest current if the Earths 3.00105 T field is parallel to the ground and is not neglected? (c) Is the supported wire in a stable or unstable equilibrium if displaced vertically? If displaced horizontally?
Gluconeogenesis – formation of glucose from non-carbohydrate sources (comes from protein) – because 58% of amino acids can be converted into carbs Ketone bodies are waste product of fat metabolism In brain disorders, the brain really likes fat (ketone bodies) During periods of starvation, there is a down regulation of metabolic rate and the breakdown of protein Metabolic rate can slow down to 40% to keep you alive during starvation After we use fat as an energy source, we revert back to breaking down protein from muscles right before death S o Hypothermia – lower body temp – tells us that boys has lowered metabolic rate o Bradycardia – the second physical sign that an athlete is under-fueled. o Urinary ketones – means they are starving and breaking down fat If calorie intake is too low, you will see ketones mid day o Often see increase in urine specific gravity-ketones, because you are producing more and are peeing more out. When people are put on a high fiber diet and are constipated, it becomes a motility issue (peristalsis) get them more liquids Postural Orthostatic tachycardic Syndrome – when you stand up fro a laying position, your HR elevated by 30 beats. o Blood pools in lower body and brain is blood deprived Could be caused from underfueling, dehydration If under fueling is significant enough, women miss their periods – estrogen goes away osteoporosis (estrogen helps with bone deposi
