Sustainable Strategy for Algae Biomass Waste Management via Development of Novel Bio-Based Thermoplastic Polyurethane Elastomers Composites
PublicationThis work concerns the waste management method of algae biomass wastes (ABW). For this purpose, we prepared bio-based thermoplastic polyurethane elastomer (bio-TPU) composites. Algae biomass wastes are derived from algal oil extraction of Chlorella vulgaris and from biomass of Enteromorpha and Zostera marina. ABWs were used in the bio-TPUs composites as a filler in the quantity of 1, 5, 10, and 15 wt.%. The bio-based composites...

Hydrogeochemia strefy kontaktu wód słono-słodkich na wybrzeżu Bałtyku na przykładzie rejonu Ustki
PublicationOpisana strefa kontaktu wód słodkich ze słonymi w rejonie Ustki zachodzi w warunkach wnikania zasolonych wód kanału rzeki Słupi do płytkiej warstwy wodonośnej. Ta sytuacja zachodzi głownie w okresie podpiętrzenia wód kanału przez morze w czasie jesienno-zimowych sztormów. W Ustce stwierdzono wyraźną zmienność czasową i przestrzenną składu chemicznego wód podziemnych płytkiej warstwy wodonośnej. Wzrost stężeń mineralizacji ogólnej...

ZNACZENIE ŹRÓDEŁ POCZUCIA SAMOSKUTECZNOŚCI U POCZĄTKUJĄCYCH PRZEDSIĘBIORCÓW – RAPORT Z BADAŃ
PublicationPoczucie samoskuteczności w sposób istotny wpływa na zachowanie ludzi sprawiając, że stają się oni bardziej wytrwali w działaniu i stawiają sobie ambitne cele. Poczucie samoskuteczności powstaje pod wpływem doświadczeń jednostki, a jego poziom jest możliwy do kształtowania. Zdaniem Bandury (1997) istnieją cztery źródła poczucia samoskuteczności, czyli poprzednie doświadczenie, pobudzenie fizjologiczne, obserwacja innych oraz perswazja....
