Effect of soil scarification on natural regeneration of mature scots pine (Pinus sylvestris) stands in Greece

by

Grigoriadis Nikolaos et al. View all

Ecosystems and Natural Resources Management

The natural regeneration of Scots pine stands at the Sarakatsana location in the Pieria Mountains improved considerably after the removal of the dense ground vegetation followed mechanical soil scarification. The experimental design consisted of replications on scarified and non-scarified soil. The...

Evaluation of several commercial polymers as support for TiO2 in photocatalytic applications

by

Fernando Gutiérrez-Martín et al. View all

This work is aimed to select the best synthetic polymers available in the market with high transmittance in the TiO 2 activation range that can be coated with the semiconductor and withstand the photocatalytic oxidation conditions. Among eleven commercial organic polymers with different additives...

Preliminary study of the effect of using biosorbents on the pollution of the treated water

by

Hossam Altaher et al. View all

Water and Wastewater Treatment

Several adsorbents have been tried out by researchers to remove different pollutants from wastewater. However, the adverse effect of these biosorbents on the treated water and the possibility of leaching new pollutants to the treated water have not been investigated. A batch technique was employed...

E2KW 2013

In this work, the stopping power due to free and bound electrons in a plasma target is analyzed for two different kinds of projectile, protons and alpha particles. The stopping of free electrons is calculated using the dielectric formalism, well described in previous literature. In the case of bound...

The role of epoxidation on Camelina sativa biodiesel properties

by

Ángel Pérez et al. View all

E2KW 2013

An unstandarised biodiesel made from Camelina sativa oil, having over a 90 percent by weight of unsaturated fatty acids, were transformed into an epoxidised biodiesel that satisfy the requirements for iodine value, linolenic acid methyl ester content, cetane number, polyunsaturated fatty acids...

Airplane materials compatibility with blends of fossil kerosene Jet A1 with biokerosenes from babassu, palm kernel and coconut oils

by

David Bolonio Martín et al. View all

E2KW 2013

Currently there is a big interest to increase the sources of alternative fuels for aviation to get a reduction of their carbon footprint and the deep energetic dependence from fossil fuels of different countries. Although there are studies about how to produce this alternative fuel and if it...

Effect of alternative fuels on diesel low temperature combustion

by

Juan José Hernández et al. View all

E2KW 2013

A set of experiments have been carried out in a heavy duty single cylinder engine using high EGR rates and different start of injection angles ( SOI ). Three different fuels (conventional diesel fuel, a diesel-ethanol mixture (e-diesel) and a Fischer-Tropsch fuel (GTL)) have been tested in order to...

Sustainability study of biodiesel from Acrocomia totai

by

Magin Lapuerta et al. View all

E2KW 2013

The aim of this work is to quantify the life-cycle emissions in terms of CO 2 equivalent grams per megajoule of biodiesel produced from Acrocomia totai, a native oily seed from Paraguay, according to Directive 2009/28/EC. The other key point is to calculate the amount of energy invested to get a...
