A bacterial sample from a patient was gram stained using standard protocol. The results of the gram stain showed pink rods and purple circles under the microscope. If you were to streak this patient sample on nutrient agar plates to isolate colonies, which of the following, plate A or plate B, would best represent the sample?

The PAT consists of assessing the appearance of the patient, the patient’s work of breathing and their blood pressure.

A simply supported beam with dimensions of b = 16 in., h = 28 in., d = 25.5 in., and L = 23 ft supports a uniform service (unfactored) dead load of 2.266667 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.4 kips/ft. The beam is reinforced with five No. 6 Grade 60 bars. The concrete strength is 10,000 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Using the effective moment of inertia, determine the immediate mid-span deflection of the beam due to the combined service loads (dead plus live).The effective moment of inertia Ie = 9,103.4 in.4.

A simply supported beam with dimensions of b = 14 in., h = 22 in., d = 19.5 in., and L = 25 ft supports a uniform service (unfactored) dead load of 1.720833 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.5 kips/ft. The beam is reinforced with five No. 7 Grade 60 bars. The concrete strength is 5,800 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 53.75 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 251.6 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 6.1763 in.
