REDUCTION OF THE ENVIRONMENTAL IMPACTS OF REINFORCED CONCRETE COLUMNS BY INCREASING THE COMPRESSIVE STRENGTH: A LIFE CYCLE APPROACH

Reduction of the environmental impacts of reinforced concrete columns by increasing the compressive strength: a life cycle approach

Abstract The building industry is one of the greatest environmental impact causers in the planet.Cement is the second most used material in the world and the consumption of concrete ranges between 20 to 30 Gt yearly.This demand for the materials ten ds to increase for the next 100 years.The increase of concrete strength to reduce the material consu

Hydrophobic coatings based on SiO2

The method of conversion, properties and usage of hydrophobic coatings on the bases of silicon dioxide is presented in the article.These layers are formed by use the silanes which are sophie allport bee curtains not react with water.What is more, these layers could provide not only great resistance to the effect of water molecules, but also better

Breaking barriers: pCF10 type 4 secretion system relies on a self-regulating muramidase to modulate the cell wall

ABSTRACT Conjugative type 4 secretion systems (T4SSs) are the main driver for the spread of antibiotic resistance genes and virulence factors in bacteria.To deliver the DNA substrate to recipient cells, it must cross the cell envelopes of both donor and recipient bacteria.In the T4SS from the enterococcal conjugative plasmid pCF10, PrgK is known to
