WEEE transport from the collection platforms to the first treatment

The EI datasets Transport, lorry 3.5–7.5 t/EURO 3 and Transport, lorry 3.5–7.5 t/EURO 4 (50% each) were used for the modelling of the transport.

The eight mixtures were moistened up to CCG 2046 water content of 5.5 kg H2O/100 kg dry solid. Cylindrical test specimens of 50 mm diameter and 3–4 mm thickness were formed by uniaxial dry pressing at 300 kg cm−2 and dried in an oven at 110 °C for not less than 24 h. The bulk density of the green samples, and later of the sintered ones, was measured by mercury displacement.
The green specimens were sintered in two steps (Fig. 1). Initially, the starch was oxidized in a amensalism muffle furnace with a slow treatment characterized by a maximum temperature of 500 °C and a soaking time of 1 h (K60L, Nannetti Spa., Italy). Finally, the specimens were sintered in a fast electric kiln (Pirometrol S.A., Spain). This last thermal step was designed to balance the porosity and mechanical strength in the sintered membranes, and was characterized by a soaking time of 1 h at 1100 °C.

At the beginning of the

Over the second year, the influence of the application of organic amendments on the soil nitrogen dynamic was less evident. One year after application (spring), organic-amended soils showed low availability of mineral nitrogen, despite better conditions for an increase in N mineralization processes. These results concur with Ochoa-Hueso et al. (2013), who found a minimum of mineral N availability in spring in a semi-arid Mediterranean soil. Three months later (summer, 15 months after application) we found a slight increase in NH4+-N and NO3−-N content in amended soils, probably due to increased temperatures and an early rainfall 2-APB (see Fig. 2) which promotes soil microbial activity. However, a response to a drought period – typical of the Mediterranean climate – was observed in autumn. In this sampling (18 months after application) we found a sharp increase in NO3−-N content at both monitored depths (Fig. 5). The increase in NH4+-N content in summer and its decrease in subsequent samplings may be due to the nitrification process, as observed from the increase in NO3−-N content. Although the drought effect could decrease soil microbial activity, many authors have demonstrated that nitrifying communities may be metabolically active in a semi-arid soil during the dry season (Gleeson et al., 2008, Parker and Schimel, 2011 and Sullivan et al., 2012). However, we observed high potential nitrification only in MSWC soils. Cruz et al. (2008) found a high NO3−-N content in a Mediterranean soil during the dry season. As previously discussed, this leads to a greater likelihood of the nitrate moving into the deeper layers of the soil after autumn and early winter. The rainfall accumulated until the sampling (100 mm, 21 months after application) may cause an increase in NO3−-N (20–40 cm) content, causing it to be higher than the topsoil content.

1. Introduction
In palisade study, GZO films are grown by plasma-assisted molecular beam epitaxy (PA-MBE). An in-situ post-annealing process under Zn overpressure is used to improve the electrical properties and suppress the generation of acceptor-like defects. GZO films with different growth temperatures are also investigated with respect to the electrical, structural and optical properties.

Between the dreier ring layers of Ba Eu Al Si

6 shows examples of stacking variations with the punctuated equilibrium slabs of model 1, only with different orientations of dreier-ring layers and the slab layers. Wide varieties of stacking sequences could be possible, which would cause diffuse lines and streaks in the ED and XRD photographs. These faults could not be distinguished from the c-axis direction, as shown in the projection of the average structure on to the b–c plane 'CHIR-98014' ( Fig.

2.1. Synthesis of Ca5Co4V6O24
2.2. Synthesis of Ca5Ni4V6O24
Similar to Ca5Co4V6O24, single crystals of Ca5Ni4V6O24 were obtained using Bruceine A mixture of CaCO3 (3 N, 1.2712 g), Ni(AC)2 (2 N, 2.4856), and V2O5 (3 N, 1.4063 g) as the starting materials. The mixture was ground well and packed into an alumina crucible with a cover. After the furnace was heated up to 950 °C and kept at 950 °C for 12 h, the furnace was slowly cooled to 450 °C at a rate of 5 °C/h and then cooled to room temperature at a rate of 50 °C/h. With this procedure, yellow crystals of Ca5Ni4V6O24 were obtained by mechanical separation from the quartz tube. Powdered samples were synthesized at 600 °C in air with several intermediate grindings using a mixture of CaCO3, NiO, and V2O5 with a molar ratio of 5:4:6. The product was finally sintered at 850 °C for two days. The quality of samples was confirmed by powder X-ray diffraction (Fig. S1).
