The result of water vapour permeability measurement and DWL% after salt crystallization test (15 cycles)

Context 1
... behaviour suggests that the biomimic apatite could be a suitable consolidant for SS, because it does not dramatically alter the water suction behaviour of original stone materials. On the other hand, the formation of hydroxyapatite induced the reduction of the water vapour permeability value around 20% (Table 1: 84 g/m 2 24h for SS and 68 g/m 2 24h for SSA), indicating that the treatment affects the breathing function of the stone to an acceptable extent. ...Context 2
... specimens started to damage rapidly after 10 cycles may be due to the super saturation of salt inside stone matrix. On the contrary, treated stone specimens (SSA) showed better performance than untreated stone and started to damage after 15 cycles of the salt crystallization test (the difference of DWL at the end of the test was around 38%), confirming the good consolidation effect provided by hydroxyapatite (Table 1). ...Context 3

Erittäin rehevässä, Natura-ja Ramsar-ohjelmiin kuuluvassa Kangasalan Kirkkojärvessä kokeiltiin ravintoketjukunnostusta heikentyneen linnustollisen arvon ja veden laadun parantamiseksi. Pohjaeläinravintoa käyttävien uhanalaisten sotkien määrät kasvoivat särkikalojen vähentämisen jälkeen, mutta yllätyksiltä ei vältytty.
