Prediction models based on soil properties for evaluating the uptake of eight heavy metals by tomato plant (Lycopersicon esculentum Mill.) grown in a…
2021
The aim of this study is to design de novo prediction models in order to gauge the likely uptake of eight heavy metals (Al, Cr, Cu, Fe, Mn, Ni, Pb and Zn) by Lycopersicon esculentum, the tomato plant. Uptake was assessed within the plant’s root, stem, leaf and fruit tissues, respectively. The plant was cultivated in soil amended by different application rates of sewage sludge, i.e. 0, 10, 20, 30 and 40 g/kg. The roots exhibited markedly elevated heavy metal concentrations compared to the above-ground plant components, with the exception of the quantity of Ni in the leaves. Apart from Al, Fe and Mn, a bioconcentration factor >1 was identified for all heavy metals. Excluding Ni in the leaves,…
New land valuation criteria after the Spanish 2011 Valuation of Land Regulation : the objectivation of building expectations in rural land
2013
The land valuation regime has undergone one of its most important modifications at the hands of the 2008 Land Act and its 2011 Regulation. According to the so-called objectivity principle - which defines all established methods for the new basic situations of land - and according to the stated prohibition of taking into consideration building expectations arising from granted planning permission, the fact is that the existence of circumstances that are not a natural consequence of landowner investments made on the property is easily deducible. This is inconsistent with the spirit of the Land Act in force contained in its Explanatory Memorandum.
Uptake prediction of nine heavy metals by Eichhornia crassipes grown in irrigation canals: A biomonitoring approach
2021
The principal objective of this study is to generate mathematical regression equations that facilitate the estimation of the extent to which Eichhornia crassipes (C. Mart.) Solms, water hyacinth, absorbs heavy metals (HMs) into four plant organs (laminae, petioles, roots, and stolons). This study considers the absorption of nine HMs (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn), and the E. crassipes evaluated in this study were located in three irrigation canals in the North Nile Delta in Egypt, with sampling being conducted in both monospecific and homogenous E. crassipes. Samples of both E. crassipes and water were collected on a monthly basis during one growing season. Analysis of the water s…
FIFA World Cup 2006 and its legacy on tourism
2007
This chapter discusses the legacy of the FIFA Football World Cup 2006 and its effects on tourism. First of all, the ‘concept of legacy’ is defined. The problems of measuring and forecasting tourism legacy are then discussed. Facts are presented which demonstrate that benchmarks and methods for measuring tourism growth triggered by a major football tournament are not relevant for detecting event tourism legacy. Hence, a bottom-up approach is introduced, which identifies the event legacy by evaluating all football World Cup-related changes in the host cities and the host country. These changes are the so called six ‘event structures’ (infrastructure, knowledge, image, emotions, networks, cult…
