Assessment of Physical and Hydraulic Properties Three Rockwool Types in Comparison with Wheat Straw Sawdust as Greenhouse Growth Media

Rockwool, as an inert medium covered or bagged with polyethylene film, can be effectively used for plant culture in space station. The most important machine is the pump adjusting the dripping rate in the feeding system. Hydro-aeroponics may be adaptable to a space laboratory. The shortening of the light-dark cycles inhibits plant growth and induces an abnormal morphogenesis. A photoperiod of 1...

Glasshouse experiments were conducted to study infection and disease development in rockwool-grown rose plants inoculated with Ralstonia pseudosolanacearum. A R. pseudosolanacearum strain isolated from was more aggressive than strains anthurium or curcuma. The three cultivars tested, Avalanche, Red Naomi Armando, differed susceptibility. At 20 oC, the caused hardly any symptoms over a six weeks...

The present study explores the physical-mechanical and tribological properties of hybrid wood fiber rockwool-reinforced asbestos-free resin-based friction materials. We developed brake composites with different contents (wood rockwool fiber) at a total fixed loading 30%. Then, were investigated on physical, mechanical, according to industry standards. results show that, increase in fiber, densi...
