CONT

Physical research chemist at DuPont's Experimental Station using an analog computer to determine the temperature characteristics of a bar of silicon. It is undergoing refinement by the floating zone technique which involves gradual moving of the silicon through a furnace so that a small part of the bar is molten at a time.

  • Titles of Federal Government Programs (Canadian)
OBS

Realizing that this discovery [the transverse-excitation technique] had just paved the way to a new generation of high-energy-pulse lasers at high repetition rates, DREV [Defence Research Establishment, Valcartier] decided to formalize under project LOTION all research efforts directed to the refinement of the novel transverse-excitation technique for CO2 lasers... Project LOTION was terminated in January 1970 with the public disclosure of the DREV TEA-CO2 laser.

Key term(s)
  • LOTION

French

Domaine(s)
  • Titres de programmes fédéraux (Gouvernement canadien)
OBS

Prévoyant que cette découverte [la technique d'excitation transversale] allait engendrer rapidement un nouveau type de laser à impulsions de haute énergie et de haute cadence, le CRDV [Centre de recherches pour la défense, Valcartier] groupe en un projet appelé LOTION toutes les activités de recherche visant à améliorer cette nouvelle technique d'excitation pour les lasers CO2 [...] Le projet LOTION prit fin en janvier 1970 lorsque le Centre divulgua son invention du laser CO2 TEA.

Subject field(s)
  • Museums
  • Restoration of Works of Art (Museums and Heritage)
CONT

Foundation research results in new knowledge and/or techniques that are required as building blocks for other types of research within CCI [Canadian Conservation Institute] their own, answer a conservation question. Foundation research at CCI normally involves either the study of materials(in order to understand the chemical and physical properties of heritage materials) or the development or refinement of scientific methods that are required for other research. Examples of our foundation research include a study of iron corrosion mechanisms, and the development of a technique to measure the degree of polymerization of cellulose in paper.

CONT

La recherche fondatrice donne lieu à de nouvelles connaissances et à de nouvelles techniques qui sont nécessaires comme fondements pour d'autres types de recherche au sein de l'ICC [Institut canadien de conservation], mais qui, à elles seules, ne répondent pas à une question de conservation. À l'ICC, la recherche fondatrice englobe normalement l'étude des matériaux (pour comprendre leurs propriétés chimiques et physiques) ou l'élaboration ou le perfectionnement des méthodes scientifiques qui interviennent dans d'autres types de recherche. L'étude des mécanismes de corrosion du fer et la mise au point d'une technique pour mesurer le degré de polymérisation de la cellulose dans le papier sont des exemples de recherche fondatrice.

English

Subject field(s)
  • Genetics
  • Law of Evidence
CONT

DNA testing : In little more than a decade, DNA(deoxyribonucleic acid) evidence has become the foremost forensic technique for identifying perpetrators, and eliminating suspects, when biological tissues such as saliva, skin, blood, hair, or semen are left at a crime scene.... Over the years, the technology has undergone rapid change and refinement that has increased both its capability to obtain meaningful results from old evidence samples and its discriminatory capabilities.

Key term(s)
  • deoxyribonucleic acid testing

French

Domaine(s)
  • Génétique

CONT

Une cour d'appel du Texas a ouvert la voie [...] à la conduite de tests ADN réclamés par le condamné à mort américain [qui] assure que ces analyses l'innocenteraient [...]

Key term(s)
  • conduite de tests d'acide désoxyribonucléique
