Abstract: Methods are provided for upgrading asphaltene-depleted crude fractions. The asphaltene-depleted crude fractions are upgraded by oxidizing the crude fractions by air blowing. Upgrading an asphaltene-depleted crude fraction can allow more valuable grades of asphalt to be formed from the crude fraction. Alternatively, upgrading an asphaltene-depleted crude fraction can allow for incorporation of a greater percentage of such a crude fraction in a blend of crudes that are used for making a desired grade of asphalt.

Abstract: An otter habitation section, an overland section, an inclined-surface section, a first spawning section, a second spawning section and a roost are all provided. Accordingly, otters and birds can sufficiently obtain preys, and fishes secure a spawning ground suitable for spawning characteristics. Therefore, the otters, the fishes and the birds can inhabit together.
