Oral presentations concluding

There should be an oral presentation towards the end of the semester to the management (which is your classmates, the professor, and the invitees) on your business plan for a proposed new product on the innovative product idea, on market and technology analysis, on the financial and environmental analysis, and on your recommended action. Be prepared to answer searching questions from your management, and to hear constructive comments intended to improve your research, your analysis, your recommendation, and your presentation skills. If time permits, it would be useful to take all the comments and constructive suggestions into consideration, and make a second oral presentation. The product design project concludes with the submission of a written report, which would be in parallel with the traditional process design project. 

A typical experiment relating to stability is that of April 2, 1957. Five ml of 1% LSD-25 (5.0 mg of LSD, the equiwilent of 500 100 meg oral doses) was nebulized for 10 minutes. On the basis of previous data with PSP, it was estimated that 15 mg of LSD entered the chamber. The samplers were mn so that 100 meg of LSD-25 should have been collected from 218 liters of air. It was concluded from this experiment that, at the end of 10 minutes of nebulization about 0.5 meg of LSD per liter was present in the air, on the average. 

In excerpts 8C and 8D, moves 1 and 2 are accomplished in a single sentence. (In one case, two statements are linked by a semicolon in the other case, two statements are linked by but. ) In just a few words, the topic is identified and a gap is suggested. The remainder of both abstracts is devoted to move 3. Methods are mentioned briefly, but results are emphasized and numerical values are included. Both abstracts conclude with a sentence that states the implications of the work—specifically, that litter mercury is accumulating in soils (excerpt 8C) and that stored beer maintains phytonutrients (excerpt 8D). Abstracts do not typically end in this way, in part, because when abstracts are written, implications are usually not known. However, if implications are known, they are often included. (Implications of the work are nearly always addressed in the final oral or poster presentation.)... 

The book concludes with Part 6 dealing with several new developments in the field of antitumor Pt compounds. Farrell et al. present novel di- and trinuclear Pt11 compounds which display marked antitumor activity and, at the same time, have DNA-binding properties different from those of cis-platin. Kelland describes orally active PtIV drugs presently in Phase-I and Phase-II clinical trials. New and fast mechanism-based methods for screening Pt compounds for potential antitumor activity are the topic of the chapter by Sandman and Lippard. Finally, Kozelka critically examines the contribution that computational studies can make to the field of Pt-nucleic acid interactions. He ends with an optimistic outlook for using ab initio molecular-dynamics calculations in the near future. 

In preliminary studies by Rollins et al., single and multiple oral doses of codeine were administered to drug-free volunteers. After a single dose, codeine was present in the hair bulb within 30 min and peak concentrations were observed at 2 h. The concentration of codeine in the hair bulb decreased over 48 h following a single dose and over 4 weeks following multiple doses. The concentration of codeine in distal hair segments reached a relatively steady concentration within 3 weeks. It was concluded that codeine is rapidly distributed into the hair bulb and a portion is distributed back into the plasma only a fraction is permanently incorporated into hair. 

Few papers that mention a possible association between calculus and caries have been reported since that time. In the most focused of these, Manji et al. [23] presented data from an oral health study involving 1131 Kenyans aged 15-65 years. By dividing the subjects into narrow age bands, these authors were able to demonstrate an inverse, but weak, association between calculus and caries. They concluded that the correlation was not strong enough to be of clinical significance. Of five further relevant studies [24-29], an inverse association between calculus and caries was reported in three [24,26,27], In each case, the correlations were weaker than those reported in section 1.2.1. 

Acid aerosols are often found in association with high concentrations of acidic gases, such as sulphur dioxide. It might, therefore, be asked whether significant depletion of nasal or oral ammonia by sulphur dioxide might occur and thus impair droplet neutralization. This was modelled by Cocks and McElroy (1984) who concluded that at a sulphur dioxide concentration of 100 qg m-3 only some 2% of the ammonia likely to be present would be removed in 10 s. The effect may be neglected. 

Despite these reservations, we may conclude that the maximal exposure to 34pg/kg/day of iodate through the use of iodized salt should present no risk for functional or structural lesions. This dose is lower than the peroral NOEL for reproductive toxicology of iodine itself (2-3 mg/kg/day) by a factor of 100, the usual safety factor for establishing acceptable daily intakes (ADI) (Beckmann and Brent, 1984). Ocular toxicity, in particular, is most unlikely to occur since repeated oral exposures to 100 mg/ kg in dogs have failed to induce retinal damage (Webster et ai, 1966). Contrary to Pahuja et, however, we...
