Moon and Moser (Israel J. Math. 1 (1962) 163-165) showed that if G is a balanced bipartite graph of order 2n and minimum degree 0>~(n + 1)/2, then G is hamiltonian. Recently, it was shown that their well-known degree condition also implies the existence of a 2-factor with exactly k cycles provided n~> max{52,2k -~ + 1}. In this paper, we show that a similar degree condition implies that for eac...

Ronstar® herbicide is one of the most effective preemergent herbicides available to professional turf managers. Unfortunately, in the South, it can sometimes be difficult to apply granular fertilizer plus Ronstar® products without causing injury to the turf. Tire tracking, discoloration and thinning turf are all symptoms that can be encountered when it is applied during the growing season, espe...

The study of partial clones on 2 := {0, 1} was initiated by R. V. Freivald. In his fundamental paper published in 1966, Freivald showed, among other things, that the set of all monotone partial functions and the set of all self-dual partial functions are both maximal partial clones on 2. Several papers dealing with intersections of maximal partial clones on 2 have appeared after Freivald work. ...

The D enantiomers of three naturally occurring antibiotics--cecropin A, magainin 2 amide, and melittin--were synthesized. In addition, the D enantiomers of two synthetic chimeric cecropin-melittin hybrid peptides were prepared. Each D isomer was shown by circular dichroism to be a mirror image of the corresponding L isomer in several solvent mixtures. In 20% hexafluoro-2-propanol the peptides c...

the effects of cattle manure vermicompost on the growth and productivity of cymbidium (cymbidium sp.) plants were evaluated under shade conditions. cymbidium was grown in a container medium including 50% pumice, 30% charcoal, 10% vermiculite and 10% peat moss, which was basic plant growth medium substituted with 10%, 20%, 30% and 40% (by volume) vermicompost. the control consisted of container ...
