English

Subject field(s)
  • Launchers (Astronautics)
  • Interplanetary Space Exploration
CONT

NASA's SLS (space launch system) is a super heavy-lift rocket that provides the foundation for human exploration beyond Earth orbit. With its unprecedented capabilities, SLS is the only rocket that can send the Orion spacecraft, four astronauts, and large cargo directly to the Moon on a single mission.

French

Domaine(s)
  • Lanceurs (Astronautique)
  • Exploration interplanétaire
CONT

Le lanceur SLS a été conçu pour envoyer à nouveau des êtres humains sur la Lune et leur permettre d'y vivre et d'y travailler. [...] La conception du lanceur SLS est faite pour évoluer selon la destination et les exigences de la mission. Il pourrait par exemple lancer Orion et d'autres charges utiles lourdes en même temps dans l'espace. Seul un lanceur SLS peut envoyer le vaisseau spatial Orion directement vers la Lune.

OBS

SLS : L'abréviation «SLS» provient du terme anglais «space launch system».

Record 4 2012-09-19

English

Subject field(s)
  • Biological Sciences
DEF

Ionic detergent used for denaturation of protein and in electrophoresis of protein subunits.

CONT

Detergent solubilization has been used with great success to study the major proteins in various membranes. Typically, the membranes are first heated to 100°C in a 1% solution of the strong detergent SDS (which disrupts all non-covalent protein-protein and protein-lipid interactions and completely unfolds the proteins), then layered on top of a polyacrylamide gel containing SDS, and lastly subjected to electrophoresis in a strong electric field for several hours. The amount of anionic SDS bound to protein is roughly equal to the mass of the polypeptide, with the result that the negative charge of the detergent overwhelms the intrinsic charge of the protein. Consequently, each individual protein migrates in the electric field at a rate determined by its molecular weight.

French

Domaine(s)
  • Sciences biologiques
DEF

Détergent ionique employé comme agent dénaturant des protéines.

CONT

Lors de l'électrophorèse en gel filtrant les protéines sont séparées selon leur taille moléculaire (ou encombrement stérique) et leur charge électrique. L'encombrement stérique d'une molécule dépend du poids moléculaire et de la configuration spatiale de la protéine. Pour mesurer le poids moléculaire d'une protéine, il faut donc éliminer l'influence de la charge et de la configuration spatiale. Un agent dénaturant, le dodécyl sulfate de sodium, permet d'obtenir ce résultat. Grâce à son affinité pour les protéines sur lesquelles il se fixe très solidement et en grande quantité, il leur confère une charge électrique constante par unité de surface et modifie considérablement leur configuration spatiale. C'est pourquoi le traitement par le SDS permet de mesurer directement le poids moléculaire d'une protéine après électrophorèse dans un gel de polyacrylamide.

OBS

SDS est une abréviation de dodécyl sulfate de sodium.

English

Subject field(s)
  • Aeronautical Engineering and Maintenance
OBS

Alenia Aeronautica and Targetti have realized a simulator which is able to reproduce the lighting conditions present when flying at an altitude of 10000 meters, inside a real airplane. ... In fact, being able to realistically reproduce natural light opens the way to potentially infinite applications: from the assessment of architectural models to studying the lighting "behavior" of materials and surfaces, to various design requirements, including aircraft instrumentation legibility tests at high quotas, which has been the particular focus of the work carried out by Alenia and Targetti. According to international regulations, aeronautical instrumentation displays, especially those of military aircraft with transparent cockpits, must be approved by tests which involve actually flying the airplane in order to assess performance in real lighting conditions. The costs and risks are obvious as is the value of creating a system which can recreate the light conditions of an aircraft in flight while it is still on the ground.

Ce «Sky Light Simulator» n'est pas le premier simulateur de lumière ambiante, mais c'est le plus grand jamais construit. Sa taille (un dôme de 12 m de diamètre) permet d'héberger l'avant d'un avion pour vérifier la lisibilité des affichages de cockpit dans des conditions d'éclairage les plus variées, allant de la nuit sans lune au plein soleil. Sa porte d'accès de 9,6 m de largeur pour 5,5 m de hauteur permet de faire entrer des avions de la taille d'un C-130 ou d'un Boeing 737.

Subject field(s)
  • Veterinary Medicine

  • Sheep Raising
CONT

Spider lamb syndrome is a heritable congenital abnormality caused by a recessive gene that produces a range of skeletal deformities in lambs. The problem, which seem to have been first observed in the early 1970's, became a topic of serious concern to breeders in the early and middle 1980's. Many of the most popular bloodlines in the Suffolk and Hampshire breeds seemingly carried this damaging gene. Sheep which had tracings in their pedigrees to suspected carriers of this gene were said "grey" pedigrees, whereas those sheep which had no apparent incidence of carriers in their pedigrees were designated as "white pedigreed" sheep.

CONT

Ovine hereditary chondrodysplasia, commonly called Spider Lamb Syndrome (SLS), is a recessive genetic disorder causing skeletal deformities in young lambs. Common features include abnormally long, bent limbs and curvature of the spine.
