Subject field(s)
  • Human Diseases - Various
CONT

They are growths, like tumours found in organs as a result of faulty development. They are normally made up of a mixture of tissues. They contain mucus-filled glands, with retention cysts, abundant connective tissue, and a chronic cellular infiltration of eosinophils. They grow at the normal rate of the host tissue and rarely cause problems such as compression. A common example of a hamartomatous lesion is a strawberry naevus. Hamartomatous polyps are often found by chance; occurring in syndromes such as Peutz-Jegher syndrome or juvenile polyposis syndrome.

CONT

The hamartomatous polyposis syndromes are a heterogeneous group of disorders that share an autosomal-dominant pattern of inheritance and are characterized by hamartomatous polyps of the gastrointestinal tract.

French

Domaine(s)
  • Maladies humaines diverses
CONT

Les polypes hamartomateux apparaissent [...] dans l'enfance et peuvent survenir tout au long du tractus gastro-intestinal, mais plus souvent dans le petit intestin (65 % - 90 %) et le côlon (60 %). Ils deviennent symptomatiques vers l'adolescence ou l'âge adulte et causent alors une obstruction, une invagination, un saignement ou une douleur abdominale. Le risque de transformation maligne des polypes est faible, mais de 3 % à 6 % présentent des changements dysplasiques accroissant le risque d'évolution vers un cancer.

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

A stability test of the upper snowpack in which a person taps a shovel placed on top of a column of snow.

CONT

The compression test finds most weak layers in the upper part of the snowpack and helps rate their stability... To start this test, use a shovel, snow saw, ski or snowboard to cut a square column with sides 30 centimetres(12 inches) wide. The column is usually about 1 metre(3 feet) tall. Place a shovel blade on top of the column. Tap with finger tips, about 10 times, moving your hand from the wrist and rate any failure as easy. Tap from the elbow, about 10 times, and rate any failure as moderate. Finally, hit the shovel blade with an open hand or fist, about 10 times, and rate any failure as hard.

CONT

Results from the compression test indicate a weakness down 65 cm. [Example approved by the Avalanche Bulletin Terminology Standardization Committee.]

OBS

Domaine(s)
  • Phénomènes météorologiques, climatiques et atmosphériques
CONT

Les essais de compression permettent de trouver les couches fragiles et d'en évaluer le degré de résistance. Ces couches se révèlent sur les parois de la colonne de neige, délimitée au préalable. On leur accorde une note en fonction de la force requise pour entraîner leur rupture. La note très facile signifie que la rupture a eu lieu au moment de la délimitation de la colonne de neige [...] Après avoir placé une pelle sur la colonne, [on tapote] la surface du bout des doigts, par simple flexion du poignet. Toute rupture à ce niveau obtient la note facile. L'étape suivante prévoit toujours un tapotement du bout des doigts, mais cette fois, en fléchissant le coude; une rupture est alors considérée modérée. Enfin, lorsqu'il est nécessaire de frapper sur la pelle avec le poing ou la main ouverte, la rupture est difficile.

CONT

Les tests de compression ont permis de déceler une couche fragile à 65 cm de profondeur. [Exemple entériné par le Comité d'uniformisation de la terminologie des bulletins d'avalanche.]

Subject field(s)

DEF

A standard of quality for the reproduction of video signals.

CONT

There is a further version of the CD-I known as full-motion video (FMV). In this format, audio and video are encoded using the MPEG standard ... This means that full-motion video with high-quality stereo can be output from a CD.

CONT

Although real motion video is the holy grail of multimedia, it still is impractical using today's technology. The current method for working with video is by capturing and converting the analog signal from a video source and either manipulating the image's data(which is written to video tape) or compressing the data using compression techniques(either software-only compression or a combination of hardware and software compression). To display or capture a single screen of an NTSC [National Television System Committee] signal, you must have a video frame grabber.... Real-time frame grabbers capture full-motion video at a rate between 15 and 30 frames-per-second using video compression...

OBS

In the NTSC format, it is achieved when the video signal is reproduced at 30 frames per second and in the PAL format, it occurs at 25 fps.

Le CD-I fait appel à des techniques très sophistiquées de compression d'images pour pouvoir stocker des images animées, très consommatrices d'espace. L'algorithme de compression est baptisé «Full Motion Video» (FMV). C'est la mise au point de cet algorithme qui a permis au CD-I de pouvoir afficher jusqu'à 72 minutes d'images animées plein écran. La qualité de l'image ainsi traitée est équivalente à celle d'un magnétoscope VHS mais inférieure à celle d'un LaserDisc.

Although real motion video is the holy grail of multimedia, it still is impractical using today's technology. The current method for working with video is by capturing and converting the analog signal from a video source and either manipulating the image's data(which is written to video tape) or compressing the data using compression techniques(either software-only compression or a combination of hardware and software compression). To display or capture a single screen of an NTSC signal, you must have a video frame grabber. These are lowest on the rungs of the video ladder, in that they have less capability than boards that capture streaming video. These cards enable you to grab a single frame of video from a Laser Disk or a VCR. Video frame grabbers come in two varieties : single-frame capture and real-time capture. Single-frame capture boards enable you to freeze a selected frame and record it to your hard disk. In this function, single-frame boards are similar to scanners-they provide a means of capturing an image and saving it for use in a multimedia title.... Real-time frame grabbers capture full-motion video at a rate between 15 and 30 frames-per-second using video compression....

Microsoft takes a "software-assisted digital video" approach to compression in its new AVI(Audio Video Interleaved) standard. It is designed to quickly decompress images from any digital storage device, though the standard is tuned for CD-ROM throughput rate of 150K per second. This loosely translates to a 160-x120-pixel, 256-color animation and a 15-frame-per-second display rate.
