Scrims both reflect and transmit light. 1  This means that if a light from a front-of-house position is shone at a scrim, then both the scrim and everything behind it will be lit. This can lead to a variety of interesting effects: 1  A scrim will appear entirely opaque if everything behind it is unlit and the scrim itself is grazed by light from the sides or from above. 2  A scrim will appear nearly transparent if a scene behind it is lit, but there is no light on the scrim.
Acalculous cholecystitis. Acalculous cholecystitis is a less common, but usually more serious, type of acute cholecystitis. It usually develops as a complication of a serious illness, infection or injury that damages the gallbladder. Acalculous cholecystitis is often associated with problems such as accidental damage to the gallbladder during major surgery, serious injuries or burns, blood poisoning (sepsis) , severe malnutrition or AIDS.
Acute cholecystitis is an inflammation of the gallbladder caused by sustained blockage of the cystic duct with subsequent changes in the bile and gallbladder. This can occur with or (less commonly) even without gallstones. During an episode of cholecystitis, the gallbladder becomes swollen and its wall becomes thickened.
