Forming Basket: There have been known, however, relatively few molecules in which a set of four or more atoms are so arranged as to form a cage or a basket. Although there have been examples of such structures, it has only recently become evident that they can be formed by elements from nearly every part of the periodic table. Some elements, such as boron, are capable of forming basket an almost unlimited number of such compounds whose structures are polyhedra. For cage or basket structures to be built, the atoms must be able to form at least three bonds; atoms capable of forming basket only two bonds cannot form anything but two-dimensional chain shapes.
More permanent installations require their own housings and these types are characterised by the basket strainer. Here, a suitably strengthened wire mesh or perforated plate shaped into a basket is placed inside a sealed housing through which the feed stream flows under pressure. In simplex systems the flow continues until the strainer is clogged with the unwanted solids. At this point the flow is interrupted and the basket is manually changed.
Box may be used, but basket is better because pet sleeps curled up. For young pet, half fill basket with soft, warm cloths and dry, soft hay or grass. For adult, use dry grass or hay only. Change bedding once weekly. |
