An otherwise healthy student in your class is infected with EBV, the virus that causes infectious mononucleosis. The same student had already been infected when she was a child, and she had merely experienced a mild sore throat and swollen lymph nodes in her neck. This time, though infected, she does not get sick. 

Her immune systemʹs recognition of this infection will involve which of the following?

A stagnant liquid film of 0.4 mm thickness is held between two parallel plates. The top plate is maintained at 400C and the bottom plate is maintained at 300C. If

the thermal conductivity of the liquid is 0.14 W/(m K), then the steady state heat flux ( W/m²) assuming one-dimensional heat transfer is

A fermentation medium is being cooled from 70^0C to 32^0C in a double pipe heat exchanger. Fluid flowing counter currently with this stream in heated from 20^0C

to 46^0C. The log mean temperature difference (in0C) for the two streams is
