In physics, attenuation (in some contexts also called extinction) is the gradual loss in intensity of any kind of flux through a medium. For instance, sunlight is attenuated by dark glasses, X-rays are attenuated by lead, and light and sound are attenuated by water.n engineering, attenuation is usually measured in units of decibels per unit length of medium (dB/cm, dB/km, etc.) and is represented by the attenuation coefficient of the medium in question.
PET Scan (Skull to Mid-Thigh) Cost and Procedure Information. Positron Emission Tomography, also called a PET scan, is a diagnostic examination that involves the acquisition of physiologic images based on the detection of radiation from the emission of positrons. Positrons are tiny particles emitted from a radioactive substance administered to the patient.
Pets usually start as a crystal, having no skills or functions until they become an Infant. In order to evolve your pet, you will need to increase its Affinity. Once the pet's Affinity reaches 100%, a button will be available next to the Affinity bar, evolving your pet into the next appropriate form.ccordingly, you can add items on the pet inventory which you can save later on to feed him or enable automatic feeding to let him eat it automatically. The checkbox on the top enables Automatic Feeding. When your pet's Hunger is lower than 80%, he will automatically eat the items available in his inventory.
