Story of the Vikings coloring book

Their contemporaries observed them as a adverse and hateful humans — faithless and harsh enemies of civilization. yet fresh proof collected from archaeological ruins and a studied reappraisal in their achievements shows that the Vikings have been greater than only a seafaring, warrior humans. They practiced a disciplined and established lifestyle, and have been certain via a strict code of honor.

Tinkering: Kids Learn by Making Stuff

After-school and out-of-school programs--as good as domestic schooling--have been becoming gradually for almost a decade, yet teachers are nonetheless looking for high-interest content material that ties into technological know-how criteria with out the pressure of present school room canon. the writer attracts on greater than twenty years of expertise doing hands-on technology to facilitate tinkering: studying technological know-how whereas playing around with genuine issues.

Sample text

Since the density of the vapour formed on the interface surface is much smaller than that of liquid, it will execute a translational motion in the direction opposite to the direction of motion of the interfacial boundary (Fig. 5a, top) with velocity wv ;  wv ¼ j  1 1 À ; qv q l ð1:6Þ where j is the density of mass flow through the interface. In the native coordinate system related to the interfacial boundary, ð~ wB ¼ 0Þ, the ~ l ¼ j=ql , evaporates, and the formed liquid leaks to the boundary with velocity w ~ v ¼ j=qv , see Fig.

This universal formula takes into account the effect of all parameters governing the gravitational ascent of bubbles, encompasses the entire possible range of variation of similarity numbers, and justifies the required passages to the limit. The formula can be used both for pure liquids and in the presence of surfactant impurities. An influence of congregate effects on the emersion of bubbles is analyzed. It is shown that during intensive bubbling the ascent rate of vapour (gas) phase can be different by many times from rise velocity of single bubbles.

Nonequilibrium phase transition regimes may be realized only for fairly specific conditions: in the presence of intensive laser radiation exposure, evaporation and condensation of liquid metals with large heat loads, surface boiling of superfluid helium and so on. Broadly speaking, such situations are not typical for bubble flows, and hence, the detailed consideration of these questions is beyond the scope of this book. A detailed analysis of modern approaches in the context of intensive evaporation may be found in Avdeev and Zudin (2012).
