In the summer of 1977/78, materials for determining the age and growth rate of Pseudochaenichthys georgianus Norman, 1937 were obtained in the South Georgia region. The 11—51 cm long fishes were of the age 1+ to 13+. The curvilinear relationship between the body length and the otolith radius took an S shape. In the first four years annual increments are almost identical and start to decrease in the following years. Spawning may occur in the 5th or 6th year of life, and hatching of larvae from eggs laid in autumn (IV—VI) takes place at the end of winter (IX of X). Larvae and juvenile fish lead an exclusively pelagic life, while older fish feed in near-bottom layers: when resources are scare there they seek food in the pelagial.

W pracy przedstawiono rodzinę zmodyfikowanych tzw. ogólnych wielomianowych krzywych przejściowych, wyznaczoną pod kątem jej wykorzystania w projektowaniu niwelety tras drogowych. Podano warunki projektowe tych krzywych oraz szczegółowe wskazówki dotyczące określania poszczególnych parametrów projektowych. Zaprezentowano również metody zastosowania tych krzywych w procesie projektowania niwelety, oparte na uzasadnionej ekonomicznie minimalizacji robót ziemnych.

Using Scopus and Web of Science databases we identified the Polish scientists with the highest number of publications, citations, and h-index in the field of pharmacy, pharmacology, and physiology. 148 such researchers were identified and then assigned to the research units in which they are employed. 31 such units were identified and analyzed.

The Poznań Branch of the PAN Archive in Warsaw was established in May 1956. From April 1974, the headquarters of the Branch was located in the building of the Poznań Society of Friends of Sciences in Poznań. The Archive collects, processes and makes available archival materials on the activities of the Polish Academy of Sciences and legacies of scholars. The legacies that form the backbone of archival resources are gathered through purchases, donations and deposits. Then they are compiled in the form of inventories and made available for research purposes. The collections of the Archive of the Polish Academy of Sciences in Poznań contain rich documentation of the history of science in Poznań and in Poland. They concern both scientific institutions, including laboratories, editorial offices and some institutes of the Polish Academy of Sciences, the University of Adam Mickiewicz in Poznań and other Poznań universities, as well as biographies of individual scientists, especially those connected to Poznań and Greater Poland. Archival collections with valuable materials related to groundbreaking events in the post-war history of Poznań and Poland are also interesting. Archival collections are also displayed at exhibitions and during scientific conferences. Archives from two legacies are available on the CYRYL portal – the Poznań Local Digital Repository.
