Barrier methods of contraception

open access: yesJournal of Obstetrics and Gynaecology, 1985
This general discussion of the value of barrier methods of contraception makes several points in the context of the British health care system. The physician should aid the couple in making an informed decision by listening. He should not let his opinions interfere for example by dissuading a man from using a condom.

Laboratory model tests on capillary barrier infiltration using actively heated fiber optic method

open access: yesYantu gongcheng xuebao, 2021
The capillary barrier effect is a natural phenomenon during the infiltration of unsaturated soil layers with different particle sizes. In order to test the capillary barrier effect of multi-layer soils, laboratory model tests are designed.
