In the article, analysis of the work conditions and the metrological characteristics of the air gauges dedicated for the roundness assessment is described. To reach the required accuracy of the acquired data, the phenomena of gas dynamics had to be analyzed in the whole flow through elements of the air gauge. A model based on the second critical parameters was used, because it reflects the true processes of the air flow. As a result, fast and accurate simulations provided series of the characteristics to be considered. Nevertheless, the chosen air gauge configuration underwent the experimental verification of its metrological characteristics. Finally, the entire measurement system Geoform with the gauge head based on the chosen air gauges underwent the accuracy test in order to make sure of its overall measurement quality.

W doświadczeniu porównano wpływ formy pożywki (dwufazowa lub stała), rodzaju cukru (glukoza lub sacharoza), chelatu żelaza (FeEDTA lub FeEDDHA) na mnożenie pędów kilku odmian jagody kamczackiej w warunkach in vitro. Na pożywkach dwufazowych uzyskano większy przyrost świeżej masy roślin w porównaniu do pożywek stałych. W przypadku pożywek stałych rodzaj zastosowanego cukru nie miał wpływu na przyrost świeżej masy, w przeciwieństwie do pożywek dwufazowych, gdzie zastosowanie sacharozy w pożywce w znaczący sposób przyczyniło się do większego przyrostu świeżej masy pędów. Na pożywkach dwufazowych uzyskano również korzystniejsze namnożenie pędów. Po zastosowaniu w pożywce chelatu żelaza FeEDDHA odnotowano większą masę oraz liczbę pędów. Jednak wyższą zawartość chlorofilu oraz karotenoidów stwierdzono w tkankach roślin z pożywki zawierającej FeEDTA.

The effect of the type of culture, sucrose and iron form included in the multiplication media for blue honeysuckle shoots was investigated. The double-phase medium culture produced more fresh plant mass compared to one-phase culture. In media supplemented with sucrose a higher increase of fresh mass was noted. All tested cultivars, except Atut, responded positively to the replacement in the medium of FeEDTA with FeEDDHA by the increasing of fresh mass. More pigments were estimated in shoots cultivated on the medium containing FeEDTA.

The author begins the article by calling attention to Duverger’s methodological principles, which he then draws on to analyse and interpret ‘Duverger’s laws’ concerning the effect electoral systems have on parties and party systems. Duverger’s classification of party systems, which he asserts are closely linked to electoral systems, is dealt with in the conclusion of the article, where the author draws attention to the more elaborate version of the classification that is hinted at in parts of his 1951 book Les partis politiques and that he then formulated explicitly in 1960. The author compares this later version with Sartori’s famous typology of party systems.

Histological studies on callus and shoot induction in culture of Trifolium nigrescens Viv. in vitro

The development of callus and adventitious shoots from hypocotyl and cotyledon of Trifolium nigrescens seedlings was studied bjr light microscopy. Calli were formed by multiplication of all living cells of explants except for cotyledonary epidermis within the first week of culture on MS medium (Murashige and Skoog, 1962) supplemented with 0.5 mgl-1 NAA and 2 mgl-1 2iP. All the shoots induced from cotyledon- and hypocotyl-derived calli were of multicellular origin and resulted from meristematic cells at peripheral regions of the callus. Copious changes in starch content accompanying callus formation and shoot initiation indicate its significant role in organogenesis of T. nigrescens.

Nature is a perfectly functioning system. Biomimetics (biomimicry) is based on analysis and transposition of processes occurring in nature to the level of technology. Architecture is a search of forms which are complementary to functional and structural solutions. There is a noticeable play with geometry, a play of shapes, and space for multiplication between these processes.

Natura stanowi perfekcyjnie funkcjonujący system. Nurt biomimetyki (biomimikry) opiera się na analizie i przetransponowaniu procesów zachodzących w naturze na płaszczyznę technologii. Architektura to poszukiwanie form będących dopełnieniem rozwiązań funkcjonalnych i konstrukcyjnych. Pomiędzy tymi procesami zauważalna jest zabawa w geometrię, gra brył oraz przestrzeń multiplikacji. Architektura może stać się płaszczyzną do swoistej gry i zabawy wychodzących znacznie poza swoje podstawowe pojęcia.
