Relevance of trade facilitation in emerging countries exports

2012

The objective of this article is to analyse trade flows in emerging nations with a maritime boundary, where trade facilitation plays a decisive role in their international development. In order to detect possible patterns in performance, we apply the economic approach of gravity models using the World Bank Logistic Performance Index (LPI) as a good proxy of trade facilitation. The results of the estimation lead to the conclusion that the more complex the transportation of goods is, the more influential the logistics indicator, trade facilitation being most prominent in Middle East exporters.

homogeneous embeddings of SL2(C) modulo a finite sub-group.

2000

L'objet de ce travail est l'étude des variétés algébriques normales complexes munies d'une action algébrique de $SL_{2}$ et qui contiennent $SL_{2}/H$ comme orbite ouverte, $H$ étant un sous-groupe fini de $SL_{2}$.Plus précisément on définit un plongement homogène de $SL_{2}/H$ comme la donnée d'une $SL_{2}$-variété irréductible $X$ (quasi-projective ou non) contenant $SL_{2}/H$ comme orbite ouverte et d'un morphisme $SL_{2}$-équivariant de $SL_{2}$ dans $X$.Les plongements homogènes lisses ainsi que les plongements minimaux (plongements lisses et complets qui ne sont pas des éclatements d'un autre plongement lisse complet) de $SL_{2}/\{Id\}$ et de $SL_{2}/\{\pm Id\}$ ont été déterminés pa…

Volatile compounds of fresh fruits of Phillyrea latifolia L.

2004

The volatiles constituents of fresh fruits of Phillyrea latifolia were submitted to investigation by GC-MS. The plants grows wild in different zones of the mediterranean region and its leaves and fruits are used as astringent, diuretic and anti-inflammatory. The volatiles were sampled by solid-phase microextraction (SPME), with a 100 mm polydimethylsiloxane fibre a 50 °C for 1 h. The headspace main components of fresh fruits of Phillyrea latifolia included limonene, β-cariophillene, eremophilene, α-muurolene, β -eudesmol e spatulenol.
