The discovery that bacteria are able to communicate with each other changed our general perception of many single, simple organisms inhabiting our world. Instead of language, bacteria use signalling molecules which are released into the environment. As well as releasing the signalling molecules, bacteria are also able to measure the number(concentration) of the molecules within a population. Nowadays we use the term ’Quorum Sensing’(QS) to describe the phenomenon whereby the accumulation of signalling molecules enable a single cell to sense the number of bacteria(cell density). In the natural environment, there are many different bacteria living together which use various classes of signalling molecules. As they employ different languages they cannot necessarily talk to all other bacteria. 2, record 8, English, - quorum%20sensing

Developing Hormosira banksii embryos, used as bioassays in toxicity studies, identified ammonium as a toxicant in secondary treated sewage effluent discharged at Boags Rocks, Victoria, Australia. Ammonium did not affect fertilization but had a significant effect on germination at 48 h and cell division at 72 h with most damage occurring in the first 48 h. Ammonium showed a similar effect as whole effluent(when expressed as mg N l-1 ammonium), sampled in June, September and November 1997, on developing H. banksii embryos. This similarity is further confirmed with comparable EC50(concentration causing an effect on 50% of the population tested) and LOEC(lowest observable effect concentration) values.

Évaluation du rapport dose (concentration)-réponse (effet). L'objectif est de déterminer la concentration en dessous de laquelle la substance ne devrait pas avoir d'effets indésirables sur la composante de l'environnement considérée. Cette concentration est dénommée concentration prévue sans effet (PNEC). Toutefois, il se peut que dans certains cas il ne soit pas possible d'établir une PNEC et il faut alors effectuer une estimation qualitative de la relation dose (concentration)-réponse (effet). Pour calculer la PNEC, on peut appliquer un facteur d'évaluation aux valeurs provenant des essais effectués sur les organismes, par exemple à la DL50 (dose létale médiane), à la CL50 (concentration létale médiane), à la CE50 (concentration effective médiane), à la CI50 (concentration provoquant cinquante pour cent d'inhibition d'un paramètre donné, par exemple la croissance), au NOEL(C) (dose (concentration) sans effet observé), au LOEL(C) (dose (concentration) entraînant l'effet observé le plus faible) ou d'autres méthodes appropriées. 4, record 18, French, - concentration%20effective

WeatherAlert is an Environment Canada weather message about impending severe weather that scrolls--or crawls--across the bottom of the television screen. Only severe weather events that are not forecast early enough for announcement on regular television broadcasts will trigger WeatherAlert messages. Test messages for WeatherAlert will be issued in the greater Toronto pilot area for these severe weather events : tornadoes, severe thunderstorms, severe winds, blizzards, heavy freezing rain, heavy snow, heavy rain and snow squalls. The Toronto area was chosen for the pilot because of its size, variety of severe weather, population and its concentration of national broadcasters. 1, record 19, English, - WeatherAlert

Alerte Météo est un message météorologique d'Environnement Canada qui annonce l'imminence d'un phénomène météorologique violent. Le message défile au bas de l'écran de télévision. Seuls les phénomènes météorologiques violents qui n'ont pas été prévus suffisamment tôt pour pouvoir être annoncés dans les émissions télévisées habituelles déclencheront des messages Alerte Météo. Des messages d'essai Alerte Météo seront diffusés dans la région-pilote du Grand Toronto pour les phénomènes météorologiques violents suivants : tornades, orages violents, vents violents, blizzards, pluie verglaçante abondante, chutes de neige abondantes, pluies abondantes et bourrasques de neige. La région torontoise a été choisie pour le projet-pilote du fait de sa taille, de la variété des conditions météorologiques, de sa population et du nombre de radiodiffuseurs nationaux. 1, record 19, French, - Alerte%20M%C3%A9t%C3%A9o
