Purpose – The Global Trade Analysis Project (GTAP) model has been used to claim that genetically modified (GM) crops have substantial positive welfare potential for sub-Saharan Africa. The purpose of this paper is to critically examine these claims with a view to seeing if this type of...

The Genetically Modified (GM) food and crops issue illustrates some key contemporary differences between the EU and the USA on environmental issues. These differences have been parallel to the apparently stronger influence of environmentalists since 1990 on a range of issues in the EU, compared...

Poly(phthalazinone ether nitrile ketone)s (PPENK) was modified with NaOH in N,N-dimethyl acetamide (DMAc) in order to find a hydrophilic resin applied in heat-resistant water-borne coatings. The properties of hydrolyzates (HPPENK) in different hydrolysis time were characterized by FT-IR and...

Several different species of ions, Au, Fe, Ag, Ti and Si, were implanted into austenite stainless steel sheets at an energy of 3 MeV respectively. The martensite transformation induced with the ion implantation was investigated with transmission electron microscopy equipped with an energy...

In the present work, a combined route involving first doping of iron or neodymium ions via sol–gel method followed by acidification of the metal-doped TiO2 particles for the improvement of the photocatalytic capability of TiO2 was reported. The obtained metal-doped/acidified TiO2...

Overland flow, which is examined here, is an important hydrological response to storms of a catchment. And it is also a main component of hillslope hydrology. Through controlling of rainfall intensities and changing of artificial slope angles, 49 overland flow hydrographs are obtained from...
