Due to global warming, many sectors have discovered sustainable methods. Many studies been conducted in various reduce carbon emissions. Cement production the construction sector causes an enormous emission, and put end this situation, pozzolan-added concrete, which is called green has into use instead of concrete produced with Portland cement. One materials used these concretes perlite. This s...

The invasion of the macroalgae Rugulopteryx okamurae is causing several environmental and economic problems along Spanish Mediterranean coasts. use composts based on R. as a peat alternative in nursery production could be valid for exploitation this organic material. present study evaluated three different substitutes potting media to grow tomato seedlings: compost okamurae, green horticultural...

The removal of volatile organic compounds (VOC) in biofilters packed with organic filter beds, such as peat moss (PM) and pine sawdust (PS), frequently presents drawbacks associated to the collapse of internal structures affecting the long-term operation. Poly(ethylene ether carbonate) (PEEC) groups grafted to these organic carriers cross linked with 4,4'-methylenebis(phenylisocyanate) (MDI) pe...

The modified technology for strengthening the surface layer of low-carbon steel machine components by electroplasma processing is proposed. This to be used as an alternative carburizing method with subsequent hardening. developed proposed based on author’s invention. parameters this process are given, resulting in a thickness reinforced 1000 µm 1700 µm. An increase microhardness 1.5 2 times (co...

Optimized mesoporous photocatalyst endowed with high specific surface area and large pore size was synthesized by sol-gel method. These large pore mesoporous materials (33.39 nm) were conducive to the movement of larger molecules or groups in pore path and for effective use of active sites. The high specific surface area (SBET, 99.23 m(2) g(-1)) was beneficial to catalytic oxidation on the surf...

Growing greenhouse vegetables is one of the most exacting and intense forms of all agricultural enterprises. In combination with greenhouses, hydroponics is becoming increasingly popular, especially in the United States, Canada, western Europe, and Japan. It is high technology and capital intensive. It is highly productive, conservative of water and land and protective of the environment. For p...
