TOPIC: The Future of the Past: Using DNA for GenealogyThe Future of the Past: Using DNA for GenealogySPEAKER: Tom Doherty (Academy of Lifelong Learning)
Thomas P. Doherty (Tom) is a professional genealogical researcher, specializing in
Delaware and surrounding counties. He wrote the Delaware Genealogical Research
Guide and was editor of the Delaware Genealogical Society Journal. He is a former
president of the Delaware Genealogical Society (DGS). Tom is also Webmaster of del-
gensoc.org (the DGS web site) and project manager of the DGS Delaware Families 1787-
1800 project. At the University of Delaware's Academy of Lifelong Learning, Tom
teaches Genealogical Research Methods combined with a Genealogy Computer Work-
shop (udel.edu/~tdoherty).
He earned an A.B. in chemistry from the Municipal University of Omaha in 1962, and an
M.S. and Ph.D. in organic chemistry from the University of Illinois in 1967. Following a
26-year career in fibers and future technology research at DuPont, Tom has been a tech-
nical consultant and technical editor for the National Textile Center.
ABSTRACT:
DNA is used in conjunction with genealogical and historical research to identify ancestors
without digging them up. DNA can also disprove the ancestors you thought you had.
Only Y-chromosomal and mitrochondrial DNA are currently used by family researchers,
limiting studies only to descent from the direct male or female lines (e.g. only two of your
16 great, great-grandparents). Y-DNA and mtDNA pass practically unchanged from
parent to child, but the remaining 22 autosomal (non-sex) chromosomes, because of genetic
recombination complexities, are not yet used extensively.
NEXT MEETING: Tuesday, September 21. Dr. Roger Horowitz (Hagley Library) will
speak on “The Chemistry of Kosher.”

Biography:Professor Esbensen received his M. Sc. in geology and geochemistry from theUniversity of Aarhus, and a PhD in metallurgy and multivariate data analysis fromthe Technical University of Denmark. He did post-doc work at the University ofUmea, and subsequently worked in geochemical exploration and industrial research.He has published work involving acoustic chemometric analysis of pitch in bulkpapermaking, in-line gas/oil pipelines, marine applications, powder transportation,grainsize distribution, granular segregation, and gasoline additives.
Senator Carper was unsure why the Green Chemistry Research and Development Act,which had passed the House of Representatives in 108th, 109th, and 110th Congresses,had been unsuccessful in the Senate. This legislation has not yet been introduced in theHouse or Senate during the 111th Congress. The Green Chemistry R&D Act has a relativelymodest scope, authorizing $55 million to NSF, NIST, DoE, and EPA to support basic greenchemistry research and to develop educational curricula that teach green chemistryprinciples. The ACS members asked Senator Carper to contact Senator Olympia Snowe’soffice to encourage the introduction of this bill in the Senate or the incorporation of itsprinciples into a larger legislative package, such as chemical regulation legislation or theAmerica COMPETES reauthorization.
The ACS members thanked Senator Carper for sponsoring S.575 (CLEAN-TEA) andS.849 (Study of Black Carbon Emissions). Sena-tor Carper indicated that the Obama administra-tion supports nuclear energy, off-shore oil and gasexploration, and development of clean coal tech-nology. The FY2011 budget allocates significantfunding for each of these areas. The Obamaadministration recently submitted three nomina-tions to fill current vacancies on the Nuclear Reg-ulatory Commission (NRC); they are expected tobe confirmed by the Senate shortly. Senator Carp-er expects that comprehensive climate change leg-islation will pass during the 111th Congress. He isencouraged by recentbipartisan discussions on this topic, particularlyfor cap and trade proposals, which will likely beimplemented for utilities, but not for manufactur-ing. Mobile sources will be addressed throughstrengthened CAFE standards. Petroleum refiner-ies will likely be addressed through an upstreamcarbon tax.
The Delaware Section Government Affairs Com-mittee thanks Senator Carper and his staff for tak-ing the time to review policy items of interest toACS.

Delaware Section Government Affairs CommitteeMeets with Senator Tom CarperMeets with Senator Tom Carper
John Gavenonis, Delaware Section Councilor
On Monday, March 8, aspart of the ACS ContactCongress initiative,John Gavenonis, AlDenio, MarthaHollomon, and AndrewEliot of the DelawareSection GovernmentAffairs Committee(GAC) met with UnitedStates Senator TomCarper in his Wilming-ton office. The meetingwas also attended byBonnie Wu (NewCastleCounty Director),Stephanie Kotin (Leg-islative Aide), and interns Will Armstrong and Ben Kim. The group gathered to discussSTEM education, green chemistry, climate change, and solar energy, which are all priorityareas for ACS policy advocacy. Position statements addressing these topics and others canbe found at the ACS website (http://tinyurl.com/acspolicystatements) or by contactingJohn Gavenonis at [email protected].
The ACS members thanked Senator Carper for his previous support of STEM educationbills and encouraged Senator Carper to cosponsor S.1210 (STEM Education CoordinationAct). This bill will require the Director of the Office of Science and Technology Policy(OSTP) to establish a committee under the National Science and Technology Council,which will have responsibility to coordinatefederal programs and activities from NSF,DoE, NASA, NOAA, Department of Education, and other federal agencies in support ofSTEM education. This bill was introduced by Senator Kaufman and the companion legis-lation passed the House of Representatives with overwhelming support. Senator Carperasked his staff to develop an opinion regarding S.1210. He is unaware of any additionalpending STEM education legislation in the Senate. Senator Carper informed the ACSmembers of the opening of the Delaware Children’s Museum at the Wilmington water-front on April 24. This museum will be another means to foster increased interest inSTEM fields, particularly among young students.

I Survived San Francisco!Al Denio, Section Councilor
Great Meeting – We flew out on March 19and reached our hotel late. On Saturday,my first meeting was the Committee onEnvironmental Improvement (CEI). Onefocus was on the ACS Sustainability effortfor which I had volunteered. This was alsothe main theme of the entire meeting. Wemust try to conserve resources for futuregenerations. Part of this effort is GreenChemistry, the program that is focused onchanging chemical processes to be moreefficient and to avoid or minimize the useof hazardous chemicals.
Since I had been serving in past months onthe Sustainability Stakeholders SteeringGroup (S3G), I was involved in several oftheir meetings and events. You will bereading more about this program in C&ENews in coming months.
I also serve on the Senior Chemists TaskForce, chaired by Eli Pearce. This is a newgroup formed to determine how to use andassist the 30% of our members who areover 60. The Chem Vets group of this sec-tion is a model that ACS is trying to pro-mote nationwide. We are hoping to getmore Senior Chemists to do outreach inschools and communities and to serve oncommittees such as Government Affairs.
The Senior Chemists Breakfast was held onTuesday morning. The featured speakerwas Prof. Robert Grubbs, a Nobel Prizewinning Organic Chemist at Cal Tech. Hedescribed how the Russian launch of Sput-nik in the fall of 1957 served as a catalystto promote a great increase in funding forscientific education and research. He sug-gested that we need a similar push to pro-mote STEM funding to compete withChina, India and Europe as they challengeour lead in science.
I spent some time at the Expo and visitedthe booths of those companies that havesigned up to exhibit at MARM 2010. Asusual, the size and diversity of the Expobooths was pretty impressive. I continue tobe amazed by the number of companies
from Europe and Asia. They were rare inthe “old days.”
Unemployment among scientists in the SanFrancisco and San Diego areas is quitehigh. Overall, 3.6% of ACS members areunemployed, much worse than the “nor-mal” 1 to 2 % of a health economy. At themeeting there was a ratio of about 10 to 1of job seekers per advertised positions.Trust me, it is good to be retired!
I actually managed to attend some chempapers at the meeting. Several dealt withthe increasing problems in treating water tomeet drinking water standards. As more ofus take more pills, many of those medicinalcompounds are excreted unchanged intotoilets and sent to sewage treatment plants.Very few American cities have treatmentplants that are up to the challenge! Thus,our drinking water supplies are becomingmore contaminated with medicinal com-pounds and their metabolites. Perhaps weshould drink more beer and wine thanwater?
Another problem is perchlorate ion conta-mination in our water supply. I have oftenread that the chief culprit is the perchloratefrom rocket fuels. However, these ions alsooccur in regions where rocket fuels werenot made or used. It appears that saltpeterimported from Chile and used in fertilizersis rich in perchlorate! Who knew? If youbuy “natural” fertilizer containing Chileansaltpeter for your “organic” garden, youhave a problem.
Overall it was a great meeting with beauti-ful weather and no earthquakes during ourvisit. We have approved a one dollar duesincrease and selected two fine candidates torun for the ACS President position. Finan-cially our organization is in good shape.
I continue to be impressed by the great ded-ication of so many members around the U.S.who give freely of their time and talents insupport of ACS. We also have a great staffin our Washington headquarters who helpour organization to function well for 365
days per year. And let’s not forget our ownExcom members who work hard on yourbehalf. If you are not yet involved in thework of the Delaware Section, I urge you topitch in and join the fun. We can use yourtalents.
Delaware Academy of Chemical Sciences –As I write this at the start of April, we awaitthe April 12 issue of C&E News. It willcontain a report on our “Nylon at 75” eventheld on February 28 at the Hagley Muse-
um. If you missed it, you may have beenwatching the final Olympic event, theU.S./Canadian hockey game. Yes, it was anunplanned and unfortunate conflict.
We are a few days away from the MARM2010 event where the DACS will have atable to introduce chemists to our 501(c)(3) educational organization. If you havenot joined us yet, please go to our websiteat www.delchemistry.org. We promise touse your talents on behalf of chemistry.
Process Spectroscopy/SAS Joint MeetingProcess Spectroscopy/SAS Joint MeetingTheory of Sampling – the Missing Link in Process Analytical TechnologiesProfessor Kim Harry Esbensen, Aalborg University, Denmark
Date and time: Monday, June 21, 11:30 AM–2:00 PM; talk to begin at 12:15
Location: Agilent Technologies, 2850 Centerville Rd, Wilmington, DE
Registration: Registration due date Friday, June 18th at noon, althoughlast-minute attendees will be accepted. Lunch will be provided.

Abstract:Chemical process analysis demands modeling based on appropriate data with respect towhat sensor signals represent in the industrial process setting. Data must be acquiredby representative sampling, ensuring accuracy with respect to lot characteristics andprecision with respect to all sampling errors. Chemometric data models must respect ademand for reliable performance validation regarding prediction, classification, andtime forecasting. Without representative process sampling the entire chain of evidenceversus the lot characteristics is flawed because of inherent materials’ heterogeneity. Itis not possible to correct for any of these deficiencies in the subsequent data analyticalmodeling. Since analytical errors typically are one or two orders-of-magnitude smallerthan the combined sampling errors, every aspect of “data quality” is in practice onlydependent upon sampling, which is either representative (acceptable) or non-representative(worthless). From the Theory of Sampling (TOS), a working minimum of principles aredelineated for both 0-dimensional (batch sampling) as well as 1-dimensional lots(process sampling). A summary of the salient criteria to be met in order to satisfy thesedemands in the PAC/PAT regimen is presented. The effect of non-representativesampling shows up as an inherent sampling bias, which cannot be estimated and thereforenever be corrected for, as well as an inflated sampling imprecision, which, if unnoticed,leads to large, futile, and unnecessary chemometric data modeling efforts. A systematicapproach is described for practical process sampling which is based on in-depth knowl-edge about the specific variability of process lots. An introductory catalogue of typicalprocess sampling misunderstandings and fallacies is presented along with a scenario forrepresentative process sampling.
