I have 8 switches but only 5 inputs to my microcontroler, so the idea was to encode( switch 1 is 0001, switch 2 is 0010......ect ). I need to keep power consumption down so I was told not to use a 74148 encoder but to use a 4067 line mux, but this doesn't help me. Is there another solution, maybe a low power encoder?

In the spectral classification of stars, there are the major classes--OBAFGKM in the old HKK system--which are subdivided into subclasses, O5, G2, G1, K2, M4. What I seek is the relationship used to compute these subclasses. What formula lets an astronomer say a star is G2 verses G3 or G5?

If the final volume of vancomycin 2 g vial should reconstituted to a final volume of 20 ml and the instructions indicate to add 13.8 ml of water, what is the powder volume of the vancomycin?

Use the following info for problems 18-20

The Pharmacy stocks penicillin G vials with 5 million units in dry powder form. The reconstitution directions on the vial are as follows.

Desired Concentration Solvent of vial
Units/ml (ml)
250,000 18.2
500,000 8.2
750,000 4.8
1,000,000 3.2

1) What volume of dry powder is contained in this container of penicillin G?

2) If the vial was diluted with 18.2 ml of sterile water, what would the volume needed for 2 million units of penicillin G be?

By that I mean, one moment its the 21st century, and in the wink of an eye, everything as we know it changes (surroundings, the clothes you're wearing, life itself) and you change (except for your mind), and this happens to everyone on the face of the earth. Its a different time period in earth's and mankind's history. This is not a dream, its reality! It's not reversable! What period in time would you like earth & its inhabitants to be living in?
