This paper presents an experimental study performed with the general aim of defining procedures for calculation and optimization of shell-and-tube latent thermal energy storage unit with metals or metal alloys as PCMs. The experimental study is focused on receiving the exact information about heat transfer between heat transfer fluid (HTF) and phase change material (PCM) during energy accumulation...
This paper presents briefly the state of the art literature review with respect to research in the field of latent heat storage systems as elements of heat only, power only or combined heat and power (CHP) plants utilizing renewable energy sources (RES) for residential applications. Next, a paper introduces initial research carried out in IMP PAN in Gdańsk, Poland, aimed at development of a prototype...
Przedstawiono wyniki badania ekotoksyczności ługów z sześciu rodzajów biomasy drzewnej wobec rzęsy drobnej (Lemna minor L.). Do badania wpływu ługów z biomasy zastosowano 96–godzinne ostre testy toksyczności. Do analizy zastosowano metodę wagową i spektrofotometr UV-VIS. Wyniki badań przedstawiają wpływ różnych stężeń ługów na wzrost rzęsy drobnej i zawartość chlorofilu.
The increasing, problem of antibiotic resistance among pathogenic bacteria requires development of new antimicrobial agents. Synthesis and experimental application of the hybrids peptides may be one of the interesting possibilities in antimicrobial treatment. The aim of the present investigation is to determinate in vitro activities of two synthetic peptide amides: cecropin-melittin hybrid peptide...
