Amongst the equipment included in instrumentation programs for the construction of embankments on compressible soils, the full profile gage makes it possible to determine the profile of the vertical settlement by measuring the hydrostatic pressure in a flexible pipe filled with liquid and placed horizontally under a structure. Four full profile gages were installed under OLGA-C, which is a test fill built by Hydro-Québec near Matagami. On the site of OLGA-C, settlement tubes, located near the full profiles gages, have provided data that could be closely compared with those given by the full profile gages. Equipped with high accuracy pressure transducers (±0.1%), the full profile gages have shown settlement values within 1 cm, on the average, of the values obtained with vertical tubes. Key words : full profile gage, instrumentation, geotechnic, settlement data, fill construction, test fill. [Journal translation]

Survival Capacity

Cryoinjuries are almost inevitable during the freezing of embryos. The present study examines the possibility of using high hydrostatic pressure to reduce substantially the freezing point of the embryo-holding solution, in order to preserve embryos at subzero temperatures, thus avoiding all the disadvantages of freezing. The pressure of 210 MPa lowers the phase transition temperature of water to -21°C. According to the results of this study, embryos can survive in high hydrostatic pressure environment at room temperature; the time embryos spend under pressure without significant loss in their survival could be lengthened by gradual decompression. Pressurisation at 0°C significantly reduced the survival capacity of the embryos; gradual decompression had no beneficial effect on survival at that stage. Based on the findings, the use of the phenomena is not applicable in this form, since pressure and low temperature together proved to be lethal to the embryos in these experiments. The application of hydrostatic pressure in embryo cryopreservation requires more detailed research, although the experience gained in this study can be applied usefully in different circumstances.
