Changes in cannabis and tobacco use trajectories from age 17 to age 23

Much like the first volume published in 2011, the second volume of this anthology series gathers a selection of analyses which are empirically based on the data of the Swiss panel study TREE (Transitions from Education to Employment). The contributions of this volume carry on the investigation of the critical transitions during youth and young adulthood, drawing on sociological, economic, psychological and pedagogical research questions and thus highlighting the analytic and pluri-disciplinary research potential of the TREE data. One of the topical foci is the long-term influence of social origin on education and labour market pathways, particularly with regard to access to higher education.

Este libro, en dos volúmenes, es un merecido homenaje al profesor Yann LE BOHEC (professeur émérite, Paris IV-La Sorbonne), jubilado forzosamente de la docencia universitaria en septiembre de 2011. La carrera investigadora del profesor Le Bohec que naturalmente continua en la actualidad ha tratado multitud de temas relacionados con el Imperio Romano, aunque deben ser destacadas en especial dos temáticas: el norte de África y el ejército romano. Y obviamente estos asuntos se ven también muy reflejados en los artículos de todos aquellos colegas y amigos que colaboran en el homenaje.

Ácido ent-16alfa,17-diidroxicauran-19-óico isolado de Ouratea semiserrata e os desafios estereoquímicos dos carbonos quirais C-4 e C-16

Phytochemical investigation of the leaves and branches of a specimen of Ouratea semiserrata led to the isolation and characterization of ent-16alpha,17-dihydroxykauran-19-oic acid, along with other natural products. This diterpenoid and its derivatives were used to unambiguous ¹H and 13C chemical shifts assignments and to indicate some mistake data described in the literature as consequence mainly of the stereochemicals of the chiral carbons C-4 and C-16. The HRMS spectra were also analysed.

Remoção dos hormônios 17β-estradiol e 17α-etinilestradiol de soluções aquosas empregando turfa decomposta como material adsorvente

This paper describes the adsorption of 17β-estradiol (E2) and 17α-ethinylestradiol (EE2) from aqueous solution by decomposed peat. The peat presented a good adsorption process, close to 76.2% for E2 removal and approximately 55.0% for EE2. Moreover, the results indicated a probable multi-layered process. Adsorption isotherms were well fitted by Freundlich model. The data were evaluated considering the pseudo-first-order and pseudo-second-order approaches, being the second more significant mechanism in the rate-controlling step. Thermodynamic data revealed that hormones adsorption onto peat is spontaneous under the employed experimental conditions. The results confirmed the potential of this adsorbent to be employed for effluents treatment.
