Briefly, one half of the mixture was exposed to electric pulses and the other half served as a control for BLM treatment alone.
To achieve vitrification, oocytes were covered by a thin film of cryoprotectant mixture and exposed to direct contact with liquid nitrogen.
One half of the mixture was exposed to eight electric pulses (1000 V cm−1, pulse duration 100 μs, frequency 1 Hz) and the other half served as a control for cisplatin treatment alone.
For the purpose of this test, analysis was made of the heat build-up of the mineral mixture when exposed to sunlight, without exposure to sunlight at night, and the drop in temperature over several days when the mixture was not exposed to sunlight.
The reaction mixture was exposed to light of 350 µmol m−2 s−1 from fluorescent lamps for 15 min. Corresponding blanks were maintained by keeping the reaction mixtures dark.
Furthermore, a falling head permeameter method was used to measure the permeability coefficients of asphalt mixture exposed to hydraulic pressures which were from 40 kPa to 350 kPa, and the correlation between permeability and hydraulic pressure was obtained.
It is found that reducing the PRF reduces the kernel development time for fixed total energy deposition due to an increased volume of unburned mixture exposed to the discharge.
For example, incubation with PCBs (0.0001 to 1 μg/ml of a mixture of PCBs (Aroclor); exposed for 24 to 48 h) significantly reduced the percentage of bovine oocytes reaching metaphase II, and lower doses that do not impair meiotic processes reduced fertilisation rates and embryonic development (Pocar et al., 2001a and 2001b).
However, the light was filtered through a 450 nm UV filter and the reaction mixture was exposed to 5 flashes of light (xenon lamp).
Thus, the present paper aims to analyze the evolution of the strength and bearing capacity of asphalt mixtures exposed to long-term moisture, several freeze thaw cycles and diverse days of thermal aging.
