A weighted multidimensional index of child well-being which incorporates children’s individual perceptions

It has been a decade since a landmark piece of work on child well-being measurement based on a summary index was developed in the United States, the Index of Child and Youth Well-Being. Several research studies, both in the U.S. and Europe, followed on from this work. However, improvements in the methodologies used by researchers are still required, namely with regard to incorporating children’s own perspectives of their well-being, as well as involving them in the measurement process. In the present paper, a composite index is proposed in order to try overcoming three of the main methodological limitations of current studies: the short account for children’s perceptions on their own well-being, the use of aggregated data, and the use of uniform and other weighting schemes that do not translate the real weights of individual indicators.child well-being, measurement, child indicators, methods

Hexane isomers sorption on the rigid framework MOF MIL-100(Cr)

In this work we studied the hexane isomers sorption on the MIL-100(Cr) [1]. The first part of the study was related to the pattern MIL-100(Cr) solid, the second dealt with the MIL-100(Cr) grafted with EtAp (Ethylamine pure) and the third with MIL-100(Cr)MEDA (Methyl ethylene diamine). The synthesis and characterization of MIL-100 (Cr), MIL-100(Cr)EtAp and MIL-100(Cr)MEDA was performed at Institut Lavoisier de Versailles. The separation and adsorption capacity of each MOF were evaluated through breakthrough experiments in a chromatographic system at LSRE using an equimolar mixture of four hexane isomers: n-hexane (nHEX) (RON 25), 3-methylpentane (3MP) (RON 75), 2,3-dimethylbutane (23DMB) (RON 103) and 2,2-dimethylbutane (22DMB) (RON 94) with the objective to the develop an adsorptive process to separate hexane isomers (kinetic diameter very similar) in order to improve the quality of gasoline measured by the octane number (RON)

Bennettitales, Erdtmanithecales and Gnetales from the Early Cretaceous of the Lusitanian Basin (western Portugal)

This paper presents a synthesis of the occurrence of extinct gymnosperms related to the Bennettitales, Erdtmanithecales and Gnetales group and discusses the stratigraphic setting of previously described specimens. These plants are represented by small fossil seeds collected from Lower Cretaceous (Berriasian to Lower Albian) fluvial siliciclastic deposits of the Lusitanian Basin, western Portugal, and probably constitute a monophyletic group, the BEG complex. The fossil seeds are composed of an innermost membranous nucellus preserved as a delicate cuticle. The nucellus is evolved by a membranous integument surrounded by a sclerenchymatic outer envelope. Plants from the BEG complex were contemporary of the earliest angiosperm having shared ecosystems with similar environmental characteristics, what reinforces its paleoecological importance

Separation of hexane isomers in metal-organic frameworks

In this work we study the effect of the functionalization of UiO-66(Zr) architecture with three different organic ligands: 2-aminoterephthalic acid (NH2-H2BDC), 2-nitroterephthalic acid (NO2-H2BDC) and 2-bromoterephthalic acid (Br-H2BDC) on the separation of hexane isomers by adsorption viewing the upgrading of TIP processes. The functionalized MOFs were synthesized and fully characterized applying established techniques: X-ray powder diffraction (XRPD), Infra-Red spectroscopy (IR), Thermo Gravimetric analysis (TGA) and nitrogen adsorption measurement. The potential of separation of the hexane isomers in the synthesized MOFs has been assessed by ISBN: 988-84-695-3536-3 T12-7 performing several screening studies in a breakthrough apparatus exploiting the effect of temperature and partial pressure, demonstrating that functionalization changes sorption behavior improving the separation between 22DMB and the other isomers. Figure 2 shows an experimental breakthrough curve performed in a bed packed with amino functionalized UiO-66 (UiO-66_NH2) where it can be seen that this material is able to separate high RON di-branched isomers (22DMB) from the low RON parents mono (3MP) and linear (nHEX) ones

Hexane isomers sorption on a functionalized metal-organic framework

A series of functionalized porous Zr terephthalate MOFs of the UiO-66(Zr) structure type bearing either Br, NH2 or NO2 groups have been synthesized at the multi-gram scale through an atmospheric pressure solvothermal route with the final aim of investigating the influence of functionalization on the separation of hexane isomers (22DMB, 23DMB, 3MP and nHEX). The studies performed in a fixed bed adsorption column with equimolar mixtures at temperatures between 343 and 423 K and partial pressure up to 10 kPa have shown that the Br, NO2 and NH3 forms exhibit an uptake reaching 15%, being the sorption selectivity hierarchy on the whole comparable to the bared UiO-66 solid: 22DMB approximate to 23DMB >> 3MP nHEX. The 22DMB/nHEX selectivity reaches approximately three at low uptake while the 22DMB/3MP selectivity of UiO-66_NO2 is nearly constant (1.3)
