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.

Answer: Not totally certain if you have any multiple choice answers or anything but here's a general idea of what I would write in response.
Explanation: First step is always going to be asking them if they're okay, the question says they're unresponsive so you want to access the situation. If they are spasming and signs lead to them having a seizure your going to immediately call for an ambulance, don't try to restrain them unless they are potentially going to hurt themselves ie. falling off of something or hitting something dangerous nearby. Restraining them can potentially damage their nerves and muscles more than just letting them flail.
If they don't seem to be having any signs of a seizure then you want to check if they're breathing. If they aren't you need to start performing cpr. Have someone nearby call an ambulance or call 911 and ask for walk-through steps if you aren't certified, that way you know what your doing and you can have that support you if they try to sue you (which won't be a problem because of the good samaritan law anyways) You want to get them laying on their back, tilt their head and make sure nothings restricting their air flow. Then your going to do a couple breaths, if they don't start breathing you'll begin compressions. Compressions, breath, compressions breath. I reccommend looking up appropriate compression techniques for different age people and how to correctly administer if you aren't already aware since I don't want to write a whole article here- I hope this helped!
Answer:
The correct term is - extrinsic stain.
Explanation:
Extrinsic stains are normally present on the surface of a tooth and occur due to taking pigmented beverages such as coffee, tea, carbonated drinks, caramel coloring, and foods. Smoking cigarettes is also one of the reasons that can cause an extrinsic stain.
This can be removed by dentists or professionals like hygienists. The stain particles act on the outer surface of the teeth and pigmented them which cause stain yellowish or brownish in individuals.
Thus, the correct answer is - extrinsic stain.
Answer:
Option B== > Amino acid
Explanation:
KINDLY NOTE that the compound in the question is attached below as a picture.
From the diagram in the picture, the compound contains an aryl group, Amine functional group and a carboxylic functional group. An Amino acid compound is a compound that has carboxyl group and the amine group which makes the answer to the question to be option 'b' that is Amino acid.
Polystyrene has formula like this:(C8H8)n, there is no amine functional group attached and there is no carboxyl functional group either which makes polystyrene not to be the answer. This the same case with vitamin D which has which has hydroxyl functional group and not carboxylic nor does it has amine functional group. Although it has been revealed through series of researches that Amino acid are good solvent for Carbondioxide, the most correct option for this question will be on identifying the correct compounds with reference to their functional groups.
Hi !
In the case of a stroke , one side of the body is generally affected more than the other side. if there is total paralysis of one side of the body, what term describes this condition?
<em>Hemiparesis, or unilateral paresis, is weakness of one entire side of the body (hemi- means "half").</em>
