A zero-one matrix is ideal if its associated covering polyhedron is integral. In this note we document the proof of a lemma of A. Lehman that was communicated to us by U. Peled in 1979 and that characterizes square minimally nonideal zero-one matrices completely. We then give a somewhat different pr

Ln the spectrum of the delayed fluorescence (DF) of pyrene, caused by triplet-triplet anndulation Tt + Tt -, Sn + SO (II = 1.2). a strong DT St -r SO and a very weak DF Sz \* SO are observed. The DF S1 -t SO IS quenched seletively by cornpounds hhe N&ethylaniline or trrethylamme which do not quench

An acxuate semi-empirical method based on the many-ekctron theory of Sinano@u for calcukting relativistic contributions to atomic energies is developed and applied to the Is', 1~~2s and ls22s2 isoelectronic seiuences in the fist and second periods. Orbital additivity of relativistic energies is test
