MEETINGS
25th ACS Middle Atlantic Regional Meeting The Silver Anniversary ACS Middle Atlantic Regional Meeting, hosted by the Delaware Section, will be held at the University of Delaware's Clayton Hall Conference Facility, May 21-23. The program features over 275 papers in 27 sessions. Ten invited symposia will be presented incorporating many eminent speakers in diverse areas: 25 Years of Excellence in Organic Chemistry; Recent Advances in Heterocycle Chemistry; Atherosclerosis and Hyperlipidemia Agents; Coagulation and Thrombosis; Modified Nucleotides as Biochemical Probes; Careers in Chemical Information; Student Award Symposium of the Chromatography Forum of the Delaware Valley; Technician Affiliate Symposium; and Undergraduate Physical Chemistry Laboratory Curricula. As a very special event, an invited symposium on Advances in NMR will honor Frank Bovey, AT&T Bell Laboratories, the 1991 winner of the Delaware Section's Carothers Award. In addition, workshops will address Occupational Safety & Health Administration safety issues for the laboratory and the role of mentoring in chemical education. A special minicourse on organic chemical nomenclature, taught by Michael Stemniski, will be offered by the Delaware Section Technician Affiliate (prior registration is required). ACS Employment and Career Services will hold a National Employment Clearing House (NECH) on Tuesday, May 21, and Wednesday, May 22, from 8 AM to 5 PM and from 8 AM to noon on Thursday, May 23. Candidates and employers may register in the NECH area beginning Tuesday morning. For information and registration forms, call John Michael Sophos, (800) 227-5558, No. 4. An exhibition of manufacturers and suppliers of laboratory equipment, apparatus, and services will be held in the Clayton Hall lobby, central to the meeting rooms, on Tuesday and Wednesday, and Thursday morning. All meals served at the Clayton Hall facility will be by preregistration. No meal signup will be available at the site. Tuesday's luncheon buffet will be followed by brief opening ceremonies welcoming all participants to the 25th MARM. David Roselle, president of the University of Delaware, will provide an official welcome from the university, and Joseph Dixon, chairman of the ACS Board of Directors, will welcome participants on behalf of ACS. A reception will be held Tuesday evening prior to the 25th Anniversary Banquet. A cash bar will be offered to supplement complimentary hors d'oeuvres. Delaware Lt. Gov. Dale Wolf, a chemist and former chemical industry executive, has been invited to discuss how an education in chemistry prepared him for his unusual career path, and to offer predictions of what the role of chemists in society in the next 25 years might be. On Wednesday, a luncheon will honor the MARM High School Teacher of the Year and the 1991 winner of the E. Emmet Reid Award for excellence in college-level chemical education. Alan L. McClelland (Director, Science Alliance) will introduce "Science Alliance—What You Can Do To Help Science Education." Wednesday evening provides a reception and banquet to honor Frank Bovey of AT&T Bell Laboratories as the 1991 Carothers awardee. Thursday's luncheon will fea-
