The actions of lophotoxin on synaptic acetylcholine receptors were investigated, using the cholinergic synapse between the lateral filiform hair sensory neurone and giant interneurone 3 in the first-instar cockroach Periplaneta americana. Lophotoxin (1-Oxl0~moll~) blocked transmission without affecting the passive or active membrane properties of the preand postsynaptic neurones, and without af...

Recently, Amdeberhan and Moll gave a conjecture on ASM sequences. In this note, we show that this conjecture is not true and we give a new conjecture.

introduction rhodium metal is known for its stability in corrosive environments, physical beauty, and its unique properties. rhodium is now widely used for alloying platinum in thermocouples, crucibles, evaporating dishes, weighing boats windings for high-temperature furnaces. it has been applied as a coating material because of the hardness and luster of its surface. rhodium is present at abou...
