Description:
The rod-like structures containing ribosome particles isolated from cell membranes of the cyanobacterium Phormidium laminosum were sensitive to RNAase and capable to incoiporate in viíro ■'♦C-amino acids into polypeptides. These facts can be considered as an evidence for the presence of protein-synthesizing apparatus in the rod-like structures of cyanobacterial membranes.

broad-crested weir, discharge coefficient, and relative height of weir
Language:
Slovak
Description:
This paper is concerned with the determination of the relationship for the calculation of the discharge coefficient at free overflow over a rectangular sharp-edged broad-crested weir without lateral contraction. The determination was made on the basis of new measurement in a range of the relative thickness of the weir from 0.12 to 0.30 and newly in a large range of relative height of the weir extremely from 0.24 to 6.8 which greatly expands the application possibilities of low weirs. In addition, the effects of friction and surface tension on the value of the discharge coefficient were evaluated as well as the effect of the relative thickness of the weir. The new equation for discharge coefficient, expressed using the relative height of the weir, was subjected to verification made by an independent laboratory which confirmed its accuracy.

Description:
The attention is directed on some specific basic concepts, quantities, ideas and mathematical relations of pulse radar signal analysis and processing under stationary linear polarized high-frequency harmonic supporting electric component. The text contains the definition of a monofrequency radar pulse and its complex representation, interpretation of the radar resolution cell volume, Fourier transform alternatives of a radar signal, explaining the principle and parts of its uniform digitalization, vector and matrix representation of a discrete pulse radar signal, reason and purpose of its processing data correction, and comment of kinds and use of similarity correlations of its pair forms., Pozornost je zaměřena na některé specifické základní pojmy, veličiny, představy a matematické relace analýzy a zpracování pulzního radarového signálu se stacionární lineárně polarizovanou vysokofrekvenční harmonickou nosnou elektrickou složkou. Text postupně obsahuje vymezení monofrekvenčního radarového pulzu a jeho komplexní reprezentace, interpretaci rozlišovací buňky radaru, alternativy Fourierovy transformace radarového signálu, vysvětlení principu a složek jeho rovnoměrné digitalizace, vektorovou a maticovou reprezentaci diskrétního pulzního radarového signálu, zdůvodnění a účel korekčního součtu dat při jeho zpracování a vysvětlení druhů a užití srovnávacích korelací jeho párových forem., and Pokračování v příštím čísle
