This report describes a patient with chylous pleural and pericardial effusions in conjunction with severe lymphoedema resembling elephantiasis. The chylous effusions and generalized lymphoedema were associated with a signet-ring cell carcinoma.

The male of Cryptothele verrucosa L. Koch, 1872, the type species of Cryptothele L. Koch, 1872, known from Fiji and Samoa, is described for the first time. It is compared with the male of C. alluaudi Simon, 1893, the single properly described species of the genus.

Three compounds containing moieties rarely encountered in nature, viz., 3-nonyloxirane-2 carboxylic acid methyl ester (1), 2-chlorododec-2-en-1-ol (2), and 2-chlorododec-2,11-dien-1-ol (3), were isolated from the red alga Gracilaria verrucosa, and their structures were determined by spectroscopic methods.

The finishing process of advanced ceramic balls can be divided into two steps. The first step is lapping in which most of the stock from the ball is removed at a higher material removal rate. The second step is polishing in which the required ball surface roughness, roundness, dimensional and geometric accuracy are achieved. In polishing, the abrasive particle size is ≤ 1 μm, and the load and s...
