Monument of History in Gdynia - Problems with Protection of the Main Representative Axis of the City
PublikacjaThe spatial idea of the main representative axis was presented in 1938 in the project of the Representative District of Gdynia and partly realised in 1938-1939. Although the whole area was included in the Gdynia's Monument of History, now its spatial integration is on thread by the controversial current development plans

Investigating the Impact of Curing System on Structure-Property Relationship of Natural Rubber Modified with Brewery By-Product and Ground Tire Rubber
PublikacjaThe application of wastes as a filler/reinforcement phase in polymers is a new strategy to modify the performance properties and reduce the price of biocomposites. The use of these fillers, coming from agricultural waste (cellulose/lignocellulose-based fillers) and waste rubbers, constitutes a method for the management of post-consumer waste. In this paper, highly-filled biocomposites based on natural rubber (NR) and ground tire...

Evaluation of long‑term immunity and protection against T. gondii after immunization with multivalent recombinant chimeric T. gondii proteins
PublikacjaToxoplasmosis caused by the opportunistic, cosmopolitan protozoan Toxoplasma gondii is one of the most common parasitoses in the world. Although it may prove dangerous or even fatal for immunocompromised individuals, immunoprophylaxis for humans is still nonexistent. Thus, the aim of the current work was to assess the ability of two immunogenic recombinant chimeric T. gondii proteins, SAG2-GRA1-ROP1 (SGR) and SAG1-MIC1-MAG1-GRA2...
