Etlhylene production by the greenl miold of citrus, Plenicilliutmit digitatuimit Sacc., has beeni investigated by a number of workers (1), but its pathway of biosynthesis and importance in fungal metabolism have yet to be defined. Factors affecting growth of the funglus have been studied intensively and a satisfactory medium has been developed (2, 7). The importance of zinc and yeast extract as...

In a study oln the effect of light quality on plant growth we found a direct relationship between IAA content and plant height (1). Of the several spectral regions used the red produced plants which were the shortest andl had the least IAA. Using low intensity radiation MIeijer (3) also obtained inhibition of elongation in red light but was able to obtain some reversal by the addition of IAA an...

The combinatorial tool of generating functions for restricted partitions is used to generalize a quantum physics theorem relating distinct multiplets of different angular momenta in the composite Fermion model of the fractional quantum Hall effect. Specifically, if g (N,M) denotes the number of distinct multiplets of angular momentum and total angular momentum M, we prove that g (N,M) ∑ k|N gL(...

Apyrases, enzymes which hydrolyze ATP (adenosine triphosphate to form AMP (adenylic acid) and orthophosphate, have been described in potato (11) and citrus fruits (1). A phosphatase which will specifically dephosphorylate AMP has been found in potato (18); however, non-specific phosphatases will also dephosphorylate this compound (2). Enzymes specifically dephosphorylating yeast adenylic acid (...

We performed Ussing chamber experiments on cultured human bronchial epithelial cells to look for the presence of electrogenic dibasic amino acid transport. Apical but not basolaterall-arginine (10-1,000 μM) increased the short-circuit current. Maximal effect and EC50 were ∼3.5 μA/cm2 and 80 μM, respectively, in cells from normal subjects and cystic fibrosis patients. The involvement of nitric o...

In the Bayesian modelling the data and the prior information concerning a certain parameter of interest may conflict, in the sense that the information carried by them disagree. The most common form of conflict is the presence of outlying information in the data, which may potentially lead to wrong posterior conclusions. To prevent this problemwe use robust models which aim to control the influ...
