New complex acids of the type H[Co( Propox·H) X] ( Propox·H=methyl-isopropylglyoxime, X=Cl, Br, I) were obtained by air oxidation of Co X in the presence of methylisopropylglyoxime. A series of new salts of these acids has been prepared and characterized by means of double decomposition reactions. IR spectra are recorded and discussed. Aquation kinetics of the [Co( Propox·H)Cl] and [Co( Propox·H)Br]-ions was studied in acidic solutions, and kinetic parameters derived were compared with those of the analogous dimethyl-glyoxime derivatives.

Reaction of 2-methylthio-thieno[2.3- d]pyrimidin-4(3 H)-ones with heterocyclic secondary amines, ethanolamine and hydrazine, resp., gave the corresponding derivatives with a basic substituent in position 2. Cyclization of the hydrazino compounds with formic acid gave derivatives of thieno[2.3- d]-1.2.4-triazolo[4.3- a]pyrimidine and [1]benzothieno[2.3- d]-1.2.4-triazolo[4.3- a]pyrimidine, two new heterocyclic systems.

1.2.4.5-Tetrahydro-3.2.4-benzothiadiazepine-3.3-dioxide ( 3a) ( 1 a) was prepared both by treating o-xylylene dibromide with sulfamide and by reaction of o-xylylene diamine ( 1 c) with SOCl or sulfamide. 4-Chloro-o-xylylene-diamine ( 2 c) and 1.2-bis(β-aminoethyl)benzene ( 8), resp., yield 7-chloro-1.2.4.5-tetrahydro-3.2.4-benzothiadiazepine-3.3-dioxide ( 4 a) and 1.2.3.5.6.7-hexahydro-4.3.5-benzothiadiazonine-4.4-dioxide ( 9), resp., on treatment with sulfamide. 3 a, 4 a, and 9 yield the corresponding N,N′-dialkyl derivatives on treatment of their Na-salts with alkyl halides. Several dialkyl derivatives of 3 a were prepared also by reaction of 1 a with N,N′-dialkyl sulfamides. [ABSTRACT FROM AUTHOR]

In 1969/70, chemical and physical parameters, phytoplankton and recent sedimentation at different levels were investigated in the mesotrophic Lake of Lucerne (Horw Bay) and in the highly eutrophic Rotsee. The rates of sedimentation came to 1277.4 g dry matter/m·year in Horw Bay and to 879.3 g dry matter/m·year in the Rotsee. The chemical analysis of sediments included the following components: total organic substance (loss on ignition), organic C, clay minerals (HCl-insoluble fraction), Ca, Mg, P, N, Fe and Mn. The Rotsee is distinguished by higher nutrient concentrations, higher rates of sedimentation (exceptions: clay minerals, Fe, to a certain extent N and Mn) and by a greater biomass of phytoplankton. The distribution and succession of selected species and groups of phytoplankton are discussed, the velocity of sinking, the degradation, the growth dynamics and the measure of trophic state are calculated. For both lakes, a phosphorus and a nitrogen balance have been drawn up. The N:P ratio continually decreases running through the nutrient cycle from the input to the storing into the bottom sediments. The intrabiocoenotic phosphorus cycle in the epilimnion is very intensive and supplies approximately two thirds of the nutrient requirements for primary production in both the Horw Bay and the Rotsee.

In tentacles and other parts of Cerianthus sp., besides a protease, a strong agglutinin has been found which agglutinates red cells of different origin and which shows an antigalactose specificity. In gonads and mantle mucus, a Blood-Group-H-like material could be demonstrated. The agglutinin is an acid protein, and can be precipitated by base polymers. For tentacles, a precipitin with anti-galactogen specificity is described and analysed. In the mantle, the commensal Phoronis australis was discovered which contained material similar to human blood, Group A. [ABSTRACT FROM AUTHOR]
