Phénomène au cours duquel des produits possèdent des propriétés chimiques habituelles déterminées par leur structure atomique ayant, en plus la particularitéd'émettre des radiations ionisantes dit des rayonnements. B) Les différents types de rayonnements...

Hobbes - Léviathan - chapitre 13 (commentaire): C'est pourquoi tout ce qui est conséquence d'un temps de guerre, où chacun est ennemi de chacun, est aussi conséquence du temps où les hommes vivent sans autre sécurité que celle que leur fournissent leur propre force et leur propre invention
En cet état de nature ou pré -politique, les hommes sont égoïstes et ne recherchent que leur satisfaction individuelle. Dans cet état, les hommes sont gouvernés par le seul instinct de conservation - que Hobbes appelle « conatus ». L'homme est d'abord et avant tout mû par l'amour de soi. Les hommes y sont égaux car le plus faible peut menacer la sécurité du fort. Ce qui caractérise l’état de nature, c’est donc la méfiance et la défiance mutuelles et la « guerre où chacun est ennemi...

Saône [Haute-] (70).
Les villes de la Haute-Saône ne constituent pas un réseau urbain : Vesoul est une des plus modestes préfectures de France ; Lure a prospéré dans l'orbite de Belfort ; Gray, dans celle de Dole et de Dijon. Le tourisme est très limité : Luxeuil-les-Bains est une ville d'eaux secondaire ; aux extrémités du département, le château-musée de Champlitte, la chapelle de Ronchamp, construite par Le Corbusier, et le parc naturel régional des Ballons des Vosges attirent quelques visiteurs.

Biodiversity.
a common molecule, ribonucleic acid (RNA), and most also have deoxyribonucleic acid (DNA). These molecules direct the production of proteins—molecules responsiblefor the structure and function of virtually all living cells. This is the evolutionary chain of life. All species are descended from a single common ancestor. From that ancient single-celled microbe, all inherited RNA. As time goesby, species diverge and develop their own peculiar attributes, thus making their own contribution to biodiv...

Narwhals, for instance, live year-round in the cool waters of the Arctic andNorth Atlantic oceans. HAVING BABY WHALES After male and female whales mate, it takes from 10 to 16 months for a baby whale to form. The lengthof time depends on the whale species. A wh...

Arkansas - geography.
temperature rises to the upper 30°s C (lower 100°s F). C2 Precipitation Arkansas receives about 1,000 to 1,300 mm (about 40 to 50 in) of precipitation a year, and some areas receive even more. Most of the rain comes during winter andspring and at times is so heavy as to cause flooding. Snow is rare in the south but amounts to more than 250 mm (10 in) a year in the mountains.

Nevada - geography.
The Truckee, Carson, and Walker rivers flow out of the Sierra Nevada, thread their way around several of the desert ranges, and also end in closed basins. The Walkerflows into Walker Lake, the Carson into Lahontan Reservoir. The major part of the Truckee’s flow is now diverted to Lahontan Reservoir, although as required by lawsome of it empties into Pyramid Lake. Because these three streams flow constantly, the lakes into which they empty never dry up. Winnemucca Lake formerly receivedoverflow w...

Michigan - geography.
The interior location of Michigan in the northern part of North America results in a continental climate, characterized by four definite seasons with moist, mild to hotsummers and snowy, cold winters. Winds off of Lakes Michigan and Superior in winter create heavy snow accumulations in nearby areas. The tempering effects of LakeMichigan account for the presence of the state’s famous fruit-growing belt along the lake’s shore. Since the water is colder than the land in spring, the westerly windspa...
