( Since the Lockerbie crash was a terrorist act in Scotland, the Staines crash remains England's worst air disaster, and Britain's worst air accident ). The crash was commemorated in June 2004, with the opening of a dedicated garden near the crash site, created at the request of relatives, and the unveiling of a stained glass window at St. Marys Church, where a memorial service was held.

Since the hospital closed its doors, a popular local legend holds that a stained glass dome in the Hall Rotunda was salvaged from the Temple of Music at Buffalo's Pan-American Exposition.

Since the introduction of the Fender Stratocaster Ultra series in 1989, ebony was officially selected as a fretboard material on some models ( although several Elite Series Stratocasters manufactured in 1983 / 84 such as the Gold and Walnut were available with a stained ebony fretboard ).

Since 1982, several stained glass windows have been installed by Quebec and New Brunswick to commemorate historical figures of New France, including Samuel de Champlain who was living when young in the village.

Since its reconstruction, the stained glass is the main feature of this space.

Since the Phage Φ-X174 was sequenced in 1977, the DNA sequences of thousands of organisms have been decoded and stored in databases.

Since blunt-ended DNA fragments have no cohesive ends to anneal, the melting temperature is not a factor to consider within the normal temperature range of the ligation reaction.

Since phosphorus is contained in DNA but not amino acids, radioactive phosphorus-32 was used to label the DNA contained in the T2 phage.

Since 1993, the circumscriptions of these two subfamilies have been changed in light of phylogenetic studies of DNA sequences.

Since the chain termination method of DNA sequencing can only be used for fairly short strands ( 100 to 1000 basepairs ), longer sequences must be subdivided into smaller fragments, and subsequently re-assembled to give the overall sequence.

Since DNA ( deoxyribonucleic acid ) can be modified only before birth, a mutation must have taken place at conception or within an egg such that an animal similar to a chicken, but not a chicken, laid the first chicken eggs.

Since that time, development of DNA has evolved through the following phases:

Since thymine nucleotides are precursors of DNA, not RNA, the prefix " deoxy " is often left out, i. e., deoxythymidine is often just called thymidine.

Since the mtDNA is inherited maternally and recombination is either rare or absent, it is relatively easy to track the ancestry of the lineages back to a MRCA ; however this MRCA is valid only when discussing mitochondrial DNA.

Since 1998 and the DNA study, many historians have accepted that the widower Jefferson had an intimate relationship with Hemings, and fathered six children with her, four of whom survived to adulthood.

Since the backbone of PNA contains no charged phosphate groups, the binding between PNA / DNA strands is stronger than between DNA / DNA strands due to the lack of electrostatic repulsion.

Since the mid 20th century chemical fluorescent stains, such as DAPI which binds to DNA, have been used to label specific structures within the cell.

Since shorter strands of DNA move through the gel matrix faster they are detected sooner and there is then a direct correlation between length of DNA strand and time at the detector.

Since the distribution of the defective mitochondrial DNA may vary from organ to organ within the body, and each mutation is modulated by other genome variants, the mutation that in one individual may cause liver disease might in another person cause a brain disorder.

: Since 98. 7 % of the DNA in humans and chimps is identical, some scientists ( but not Noam Chomsky ) believed that a chimp raised in a human family, and using ASL ( American Sign Language ), would shed light on the way language is acquired and used by humans.

Since more DNA is unfolded and being expressed, the nucleus will be darker and less uniform, larger than in normal cells, and often show a bright-red nucleolus.

Since the structure of a glycan may depend on the expression, activity and accessibility of the different biosynthetic enzymes, it is not possible to use recombinant DNA technology in order to produce large quantities of glycans for structural and functional studies as it is for proteins.

Since 2005, the Melungeon DNA Project has conducted DNA testing of identified Melungeon lines.

Since the Supreme Court's decision of that year this is more doubtful ; ;

( Since the time-span of the nation-state coincides roughly with the separate existence of the United States as an independent entity, it is perhaps natural for Americans to think of the nation as representative of the highest form of order, something permanent and unchanging.

Since it is not far from Viareggio, he will visit Puccini's house, as he never fails to do, to pay his respects to the memory of the composer of La Boheme, which he considers one of Puccini's masterpieces.

Since attack serves to stimulate interest in broadcasts, I added to my opening statement a sentence in which I claimed that German youth seemed to lack the enthusiasm which is a necessary ingredient of anger, and might be classified as uninterested and bored rather than angry.

Since the air is a continuum, the network of communication remains intact regardless of the positions or motions of the points ( the people ) in the net.

Since the hazards of poor communication are so great, p can be justified as a habitable site only on the basis of unusual productivity such as is made available by a waterfall for milling purposes, a mine, or a sugar maple camp.

Since the difficulty of drawing the net is great, we will merely discuss it.

Since a civilizational crisis involves also a crisis in private interests and in the ruling class, reaction is normally found among those who feel themselves to be among the ruling class.

Since civilizational change is the most difficult to perceive and analyze, it seldom is given adequate attention.

Since the slogans have little application to reality and are sanctimonious to boot, the applause is faint even in areas of the world where we should expect to find the greatest affection for free government.

Since more is known about Quiney than about any other acquaintance of Shakespeare in Stratford, his career may be followed to its sudden end in 1602.

Since the great flood of these dystopias has appeared only in the last twelve years, it seems fairly reasonable to assume that the chief impetus was the 1949 publication of Nineteen Eighty-Four, an assumption which is supported by the frequent echoes of such details as Room 101, along with education by conditioning from Brave New World, a book to which science-fiction writers may well have returned with new interest after reading the more powerful Orwell dystopia.

Since Laos is of no more purely military value to Moscow itself than it is to Washington, this approach might be expected to head off Mr. Khrushchev for the moment.

Since little is known about autism, and almost nothing has been written for the layman, we'd like to share one experienced mother's comments.

Since the work is done by hand, the only limitation, it is said, `` is that of human conception ''.

Since the apparatus is new, it requires experimentation and changes in technique.

Since the obvious is not always true, the Republican National Committee wisely analyzed its defeat of last autumn and finds that it occurred, as suspected, in the larger cities.

Since he has just shown who is top dog, he may not be ready to receive this highest honor in the gift of the Soviet people.

Since appeals to morality, to humanity, and to sanity have had such small effect, perhaps our last recourse is the deterrent example.

Since the goal of our international planners is a World Government, this Atlantic Community would mark a giant step in that direction for, once American economic autonomy is absorbed, a larger grouping is a question of time.
