The Effects of Child-Bearing Policies in Remarriages:Evidence from China
Fertility policy Marriages Divorces Remarriages
2016/3/18
In this paper we document the fertility policies for remarried couples in the People's Republic of China, and investigate their effects on the women's first marriages. Our evidence suggests that the c...
Vapour-phase crystallisation of silica from SiF4-bearing volcanic gases
SiF4 vapour crystallisation silica degassing
2015/9/10
Thermodynamic modelling of magmatic gases shows that SiF4 may be an important F-bearing species at the high
pressures typical of magma reservoirs. Upon decompression during degassing, SiF4 will react...
