The NASA InSight lander mission to Mars payload includes the Heat Flow and Physical Properties Package HP3 measure surface heat flow. package was designed use a small penetrator - nicknamed mole implement vertical string of temperature sensors in soil depth 5 m. itself is equipped with thermal conductivity-depth profile as it proceeds depth. flow calculated from product gradient conductivity.

The critical state theory is a robust conceptual framework for the characterisation of soil behaviour. In laboratory, triaxial tests are used to assess locus. last decades, equipment and testing procedures characterisation, within framework, have advanced obtain accurate reliable results. This review paper summarises describes series recommended laboratory locus in cohesionless soils. For this ...

lithium disilicate nano-powders were synthesized via a mild condition hydrothermal reaction at 180 ºc for 48 and 72 h with a non stoichiometric1:2 li:si molar ratio in naoh aqueous solution using li2co3 and sio2.h2o as raw materials. the synthesized materials were characterized by powder x-ray diffraction (pxrd) technique and fourier transform infrared (ftir) spectroscopy. the xrd data showed t...
