Abstract: The present application relates to method for computing the factor of safety of a slope including the following steps. Step 1: input parameters of a slope. Step 2: formulae a formula of stability number N into a target function and determine constrained conditions of geometric parameters ? and ?. Step 3: obtain a minimum stability number N. Step 4: determine a position of a critical slip surface. Step 5: transform the critical slip surface defined by ?, ? and n into a critical slip surface defined by R, xc and yc, and compute overturning moments of slid masses above and below external water level of the critical slip surface. Step 6: resolve an equivalent unit weight. Step 7: resolve the factor of safety FS.

Abstract: A titanium suboxide powder comprising Ti4O7, Ti5O9 and Ti6O11, wherein the Ti4O7, Ti5O9 and Ti6O11 provide over 92% of the powder, and wherein the Ti4O7 is present at above 30% of the total powder.

Abstract: The present invention relates to 32P or 33P-labelled bisphosphonates as radiotherapeutic radiopharmaceuticals. The 32P- or 33P-labelled bisphosphonates, which are chemically identical to the unlabelled agent, are expected to target the lesion site in an identical manner, but also deliver a significant radiocytotoxic effect to the surrounding cells. This should result, given the favorable energetics of the &bgr; particle emission from the 33P nuclide, in a loss of proliferative capacity of cells associated with the tumor lesion. The relative stability and in vivo localisation of bisphosphonates makes them good candidates as 32P/33P delivery vehicles.

Abstract: Ligands for radiopharmaceutical use are capable of chelating radiometal species and of being bound to biological targeting molecules. The ligands have formula (a) and (b), where A, A'=--SZ or Y, B.dbd.O or S, Y.dbd. (c), Z.dbd.H or a thiol protecting group, m=2 or 3, n=2 or 3, q=0 or 1, R.dbd.H or unsubstituted or substituted hydrocarbon and pharmaceutically acceptable salts, provided that at least one CR.sub.2 group represents CO and forms, together with an adjacent N atom, a --CONR-- amide group.

Abstract: A hardmetal ring is a size for size or low interference fit on the body of a disc cutter of a rock working machine, such as a boxhole borer. In one embodiment the ring is gable shaped and clamped between a fixed annular shoulder and a detachable annular shoulder. In another embodiment the ring is triangular in section and two annular shoulders resting on it and inclined surfaces on the body clamp the ring to the body.
