As an x-ray tube ages, the inside can become coated with tungsten, which can cause arcing in the tube.
When there is a short circuit inside the tube, usually from the cathode to the tube envelope, tube arcing happens. A brief loss of x-ray output and a localised artefact are the consequences. On transaxial computed tomography (CT) scans, it appears as a near-parallel, equidistant streak pattern, and on coronal and sagittal CT images, as a "horizontal" hypodense band.
The most frequent cause of x-ray tube failure is an inability to effectively disperse the heat produced during routine operation. It is common knowledge that at the anode target, heat accounts for 99% or more of the kinetic energy given to the electron beam.
Therefore, an x-ray tube ages, the inside can become coated with tungsten, which can cause arcing in the tube.

The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body.
Answer:
The best answer to the question: Evidence suggests that individudals who are overweight actually expend more calories than persons who are of normal weight, would be, A: True.
Explanation:
In recent research studies, especially carried out in Canada, it has been found out that the general belief that obese, or overweight, people, are couch potatoes and it is because of this that they are the way they are, may be wrong. Essentially, these studies followed groups of people and compared obese vs normal-weight people and found out two things: first, obese people move more in terms of steps, than normal-weight people, and two, and most amazingly, overweight people expend more calories than normal-weight people simply because their bodies, given their sheer size, have to use more energy to simply move. Thus, these studies showed that, although not by much, individuals with problems of weight do spend a bit more calories per activity, than normal-weight people.
There is not enough evidence to recommend for or against the use of vitamin E supplements for the prevention of cardiovascular disease.
What is vitamin E?
Eight fat-soluble substances that make up vitamin E include four tocopherols as well as four tocotrienols. Nerve issues can result from vitamin E deficiency, which really is uncommon and usually brought on by an underlying issue with digesting dietary fat or from a diet low in vitamin E. A fat-soluble antioxidant called vitamin E may be able to shield cell membranes from oxygen species. Government agencies from all over the world advise adults to take 3 to 15 mg daily. According to a global summary of more than 100 studies from 2016 that showed a median dietary intake of 6.2 mg of alpha-tocopherol per day, consumption was below recommendations. Alpha-tocopherol has been studied as a dietary supplement in doses as high as 2,000 mg daily, with varying degrees of success.
