Średniowieczny szczyt południowej części transeptu kościoła pocysterskiego w Oliwie
PublikacjaTransept kościoła pocysterskiego w Oliwie zawiera jedno z najciekawszych średniowiecznych zdobień architektonicznych. Występuje ono w południowym szczycie. Można wyróżnić jego trzy koncepcje. Szczyt I (po 1226 – przed 1234) ma cegły ułożone w wątek opus spicatum oraz wystające przed ścianę długie walki. Został on zniszczony w czasie napadu Prusów (1234 lub 1236). Ocalałe części przystosowano do nowego rozplanowania (szczyt II)....

Perspektywy rozwoju w Europie systemów sanitarnych z zastosowaniem toalet separujących
PublikacjaIstniejące technologie z tradycyjnymi toaletami zbiorczymi (WC), kanalizacją ogólnospławną (względnie rozdzielczą) oraz oczyszczalnią centralną niosą za sobą szereg wad i nie rozwiązują problemu gospodarki wodno-ściekowej. Ochrona wód bazuje nadal na filozofii "end-of-pipe" i oczyszczalniach komunalnych. Pomimo wysokiej efektywności oczyszczania ścieków, z obiegu przyrodniczego zostają po drodze usunięte wysoko wartościowe substancje...
