Opis:: The anatomical structure and the distribution of arabinogalactan proteins were investigated in the ovule of an energetic plant Sida hermaphrodita (L.) Rusby after pollination. Material was collected from an experimental field of the University of Life Sciences in Lublin (Felin). After embedding for immunoflurescence, semi-thin sections were stained with toluidine blue or incubated with JIM 13 or MAC 207 monoclonal antibodies for immunolabeling of arabinogalactan proteins. The structure of the ovule showed some differences in comparison to other representatives of the Malvaceae family. Conversely, the distribution of arabinogalactan proteins did not differ significantly from their distribution in the ovules of other angiosperms at the investigated stage of development.

Opis:: The study proposed the model of "guide mark" defects formation on the internal surface of pipes, produced on PRM mills of PRP–140. The research of pipe forming at plug rolling mill with stub mandrel has been carried out; regularities of the dimens ionless parameters characterizing the deformation of the gap release, depending on the reduction ratio, were determined. The model of "guide mark" defect formation on the internal surface of the pipe has been proposed. This allows for lesser wall thickness variation o f rough tubes. It has been shown that, when using dioctahedral pass designs in comparison with hexagonal pass designs the proportion of displaced volume along the pipe axis is greater but the value is lower; thereby, the risk of "guide mark" defect forming is red uced.
