Low velocity compressional wave (P-wave), Vp values, have been observed from the lunar geophysical measurements made during the Apollo 14, 16 and 17 missions. These low velocities are attributed to lack of water, low soil compaction as well as the non-consolidated nature of the regolith. The microgravity lunar regolith simulant velocity experiment (?-SVeLSE) aims to determine if there is any dependence of gravitational force on the seismic longitudinal velocity measurements and thus correlate with data previously ...

The production of red-clay hollow bricks belongs to the sources of industrial waste which gained on importance during the last decades. Although the amount of scrap is similar to the traditional red-clay bricks, the total waste generation is higher. As the current technologies of hollow brick production do not make it possible to provide sufficiently smooth and even surfaces, the brick blocks have to be ground after leaving the production line. This grinding generates a significant amount of waste powder containin...

most digestible form of it (puree), the potato was one of the first vegetable foods to be given to children after weaning and to convalescents who resumed their normal diet. Potato is part of the group of tubers vegetables, having as an edible organ the tubercles, which are thickened underground parts that accumulate reserve nutrients, especially starch. Potato?s food value is higher than that of other root vegetable, due to starch, vitamins, sugars and minerals salts. Taking into account the way of use, there are...

Occurrence of flash floods (floods from intensive short-term rainfall) increased in last few years because of weather changes, mostly on the small catchments. Affected small catchments are characteristic with lack of information about hydrologic data, mostly no gauging and precipitation station are established there (it is impossible to warn inhabitants). Besides that, in Slovakia is common that house building is very close to the stream, therefore is impossible to change somehow river routing, or change the cross...

The increasing amount of fiber on wheat flour brings some deleterious effects on dough structure, such as the increasing of dough stickiness and fermentation tolerance decreasing. Also it has a negative influence against other properties of dough such as handling and rising properties. Fiber addition usually causes a decrease in bread volume and breadcrumb loses its elasticity. So, we had investigated if the xylanase addition could counteract those deleterious effects. Positive action of xylanase in dough could be...
