The diatoms of Longans lake-vegetation. Fossil diatom flora. [Translation from: Acta Phytogeographica Suecica 36 73-86, 1955. ]

Sediment samples were taken from Lake Langans in Sweden and fossilised diatoms analysed. Sample methods and environmental factors are discussed. Species with a characteristic occurrence are described. The article discusses diatom-thanatocoenoses as indicators of environment.

On the problem of the distribution of Acanthocyclops viridis Jurine in the Rybinsk reservoir. [Translation from: Byulleten' Institute Biologii Vodokhranilishch 1958(1), 36-39, 1958. ]

Observations of individual weight, duration of development and production of different stages of Tropodiaptomus incognitus are presented. The study is based on data gathered from Lake Chad in 1968.

Studies on the mouth size of fish larvae. Method and conclusions only [Translation from: Bulletin of the Japanese Society of Scientific Fisheries 36, 353-368, 1970]

This study was conducted to look into the relationship between mouth size and the total length of larval fish, and the growth in total length of larval fish in one or within a one-year period. Study material was gathered in the South China Sea, the Bay of Bangkok and the Vietnamese coast. This translation focuses on methods and conclusions of the original (longer) paper.

Influence of carbon tetrachloride on the liver of tadpoles of brown frog (Rana temporaria) [Translation from: Trudy leningt.sanit.-gig.med.Inst. 82, 32-36, 1967]

Comparative studies of the structure and regeneration of tissues in different vertebrates make it possible to get ideas from the evolution and regeneration potential of tissues. In this study are considered the reactive changes in the liver of larvae of the amphibian Rana temporaria to CC14 of different concentrations. Tadpoles of different sizes and different growth were placed once each day every day in a vessel with a determined solution of CC14 in water. The liver of tadpoles has a distinctive structure. It is distinguished by structure not only from the liver of higher vertebrates, but also from the liver of the adult frogs. The liver of the latter has an insignificant amount of fat and a whole series of other characters not typical of the liver of the tadpole. Placing the tadpoles in a solution of CCl4 with a concentration of 0.1% did not produce in the liver noticeable morphological changes. The author concludes that the absence of degenerative changes in the liver tadpoles, in spite of a high percentage of death of the experimental animals, tells of the well-known resistance of their liver to the influence of CC14.

Some data on the content of organic carbon in rivers in the winter months. [Translation from: Gidrochim. Mat. 23, 36-38, 1955]

Observations are reported on the content of organic matter in the Moscow region in 1941. Some data is given on alkalinity, oxygen content and colourisation of the rivers.

Stray current corrosion of copper sheathing and keel cooling pipe of a 36' trawler

The results of investigations into the cause of an accelerated corrosion of copper sheathing and keel cooling pipe of a 36' wooden trawler are reported. The corrosion is attributed to the stray electric currents originating from the electrical wiring system. The sources of stray currents and the remedial measures have been suggested.
