DO NOT ANSWER QUESTION 10. I only need question 9 and 11 plz, answer all questions clearly and correctly. i am begging you 9. If the amount of drug in the body declines from 100% of the dose (IV bolus injection) to 25% of the dose in 8 hours, what is the elimination half-life for this drug? (Assume first-order kinetics.) (10) A drug has an elimination half-life of 8 hours and follows first-order elimination kinetics. If a single 600-mg dose...

7. Smokers are known to have about 50% higher CL than nonsmokers for theophylline. If the average observed AUC after administration of 300 mg IV theophylline in nonsmokers is 100 mg.hr/L, what is the expected AUC in smokers after administration of the same 300 mg dose? Theophylline undergoes linear pharmacokinetics 2. After administration of a single 400 mg dose of a drug, a linear plot of the serum concentration-time prorile on a semi-log graph paper showed a y-intercept of 1mg/mL...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
