When subjected to vibrating sample magnetometer analysis, "as synthesized" MNs show the saturation magnetization value of 1.8 emu/g at ambient temperature, as shown in Fig. 11a.
When subjected to freeze-thaw, samples experienced significant decrease in CBR performance.
The model has demonstrated a high level of validation and accuracy when subjected to internal split-sample validation with separate training and validation data sets.
These changes in the structure and the mineralogy reduce the durability of gypseous soil samples when subjected to freeze thaw cycles.
Thus, internal curing showed significant better performance in permeability tests in comparison with control samples when subjected to curing condition without supply of external water.
It is obvious from the above discussion that internally cured concrete performed better as compared to control samples when subjected to curing conditions without the supply of external water.
Anyway, durability towards salt crystallization is a complex matter, hence specific studies on the behaviour of HAP -and TEOS-treated samples when subjected to salt crystallization cycles are currently in progress.
The introduction of the ammonia step completely solves this problem: the same samples, when subjected to ammonia extraction, gave chromatographic profiles that were perfectly in agreement with those of the reference materials.
The approach is reported to have high statistical power for biomarker discovery in the situation of differential expression between two samples, when subjected to two different treatments, such as disease/no disease [51].
The porous structure greatly facilitated volume equilibration of these templated gels, in comparison to bulk gel samples, when subjected to changes in temperature.
In this regard, gene transfer strategies may provide effective tools to enhance the chondroreparative processes in such samples especially when subjected to mechanical stimulation as a means to reproduce the natural environment of the joint.
