Temperature and Thermal Deformation Analysis of Pump Mechanical Sealing and ring seat is established by Solidworks. The CFD model of the seal ring is explored through Navier Stokes (N-S) equation and energy equation, and variation of the temperature field is analyzed through the FEA method. The results show that for this type of centrifugal pump, the end face temper

The Account of Frost Heave and Thawing Processes When Designing Road Embankments in Cold Regionsns of embankments and their subsoils during freezing and thawing. If in case of aboveground structures (elements of buildings and transport facilities) temperature changes are accompanied, as a rule, by relatively small linear deformations, for soils—deformations of frost heave and thawing, associat

J. F. Williamsa mine. Data and data-base are processes which cannot begin without a research question. For these reasons the debate opposing hypothesis-driven versus data-driven research should be overtaken: in social research, as well as in hard sciences, data-driven research simply doesn’t exist. The last parag
