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.

3.Medicate the infected area to the best of your abilities
Answer:
The isotype of these antibodies is igG
Explanation:
Anti-Rh response are employed by medical practitioners to define the Rh antigenic profile of human blood samples.
Fetal red blood cells are necessary for increasing the production of antibodies against Rh- antigens in Rh- women who are carrying a Rh+ fetus. The isotopes of the required antibodies is IgG.
The igG antibodies have high level of affinity and are present in blood, where they can make toxins, viruses, and bacteria ineffective, and activate the complement system.
Answer:
288ng/ml
Explanation:
A serial dilution is any dilution where the concentration decreases by the same quantity in each successive step.
- Serial dilutions are multiplicative.
it to 3 rounds of dilutions for the first tube so 3x6=12 so the 300-12=288
Answer:
Adenoids
Explanation:
They help the immune system fight off viruses and bacteria. They become less important as we age.
