John is director of the local health department's communicable disease program. He has just been notified by Dr. Miller of a case of pertussis in an eighth-grade child. John is working with Dr. Miller, Ms. Gonzalez(the school nurse), and the State Department of Health to follow up on this pertussis case.John recognizes that it is imperative to follow up with case contacts to prevent transmission of the disease to others in the community. Humans are the reservoir for this disease, and transmission occurs via direct contact with respiratory droplets.
1) Which guidelines can be used to ensure proper surveillance of the outbreak.
2) How can John and his team properly alert the community and prevent panic.
3) What issues can be addressed when educating the community on preventing a future outbreak
suppose a patient is given 155mg of i-131 a beta emitter with a half-life of 8.0 days. assuming that none of the i-131
suppose you chose phenolphthalein , which changes color at the end point from colorness(acidic) to pink at pH8.5 .Would you need the same , more or less volume of NaOH in the back-titration?
What observed rotation is expected when 1.26M solution of (R)-2-butanol is mixed with an equal volume of a 0.630 M solution of racemic 2-butanol, and the resulting solution is analyzed in a sampling container that is 1 dm long
The greatest entropy of mixing
A sample of 0.7500 g of a monoprotic weak acid, HA, is mixed in enough distilled water to produce 50.0 mL of a solution with a pH of 2.716. The solution is titrated with 0.1500 M NaOH, and in the middle of the titration, when [HA] = [A-]
Determine the rate constant. b. What fraction of the initial N2O5 will remain after 13.0 h c. What is the half-life. d. If the initial concentration of N2O5 was 0.222 M, then what concentration remain after 24 h
Which of the following is an RNA codon for protein synthesis? CGU GUA
Calculate the radiation dosage (in grays) for an 85-kg person that is exposed for 7.0 seconds to a 3.0 Ci source of beta radiation. Assume that 100% of the radiation is absorbed and each beta particle has an energy of 1.7× 10-13 J.
Rates of reactions: Rate = k [A]^m [B]^n where the reaction time = 1 / Rate. Two chemical experiments were performed to determine the exponent "n". (We will assume that "m" is known).
During alcoholic fermentation, pyruvate is decarboxylated to yield ethanol and CO2. Which carbons of glucose must be labeled with 14C to yield 14CO2
If a chemist wants to make 1.3 l of 0.25 m solituion of KOH by diluting a stock solution of 0.675 m KOH, how many milliters of the stock solution would the chemist need to use
An elemental analysis shows that it contains 40.0 mass percent C, 6.71 mass percent H, and 53.3 mass percent Oxygen. Remember mass percent = grams. A determine the empirical formula. B. determine the molecular formula.
