This study focused on the long-term consequences of tubal ligation on women's lives. Women 30 to 49 years old living in Campinas, State of São Paulo (Brazil), were interviewed: 236 sterilized at least five years prior to the interview and 236 non-sterilized women. Their experiences with the currently used contraceptive methods were compared with regard to satisfaction, benefits, and damage attr...

Herbicide atrazine easily leaches to groundwater, where it is persistent. We studied whether sonication accelerates atrazine dissipation (100 mg·L−1) in vadose zone sediment slurries. Sediments were from 11.3 to 14.6 m depths in an atrazine-contaminated groundwater area. The slurries and autoclave-sterilized slurries were sonicated (bath, 43 kHz, 320 W) for 0, 5, 10, 20, or 30 min once/twice a ...

Electron paramagnetic resonance (EPR) spectroscopy was used for examination of free radicals in thermally treated vaselinum album (VA). Thermal treatment in hot air as sterilization process was tested. Conditions of thermal sterilization were chosen according to the pharmaceutical norms. Vaselinum album was heated at the following conditions (T--temperature, t--time): T = 160°C and t = 120 min,...

The reasons for using sterilized pus in the place of autogenous or other vaccines are : 1. The great simplicity and cheapness. 2. The pus is truly autogenous, this is not so with vaccines prepared from organisms grown on artificial media; for the organism is changed by such growth. 3. Besides the bacteria, pus contains toxins, and antibodies both extremely useful for therapeutic inoculation. Th...
