Absorption spectra of two orthogonal linearly polarized X-rays in a single CeCoGe3 crystal were measured at the ID12 beamline ESRF for energies near K-edges Ge, Co and L23 edges Ce. The X-ray natural linear dichroism (XNLD) was revealed vicinity all absorption edges, which indicates splitting electronic states crystalline field. Mathematical modelling comparison with experimental data allowed i...

Purpose: To investigate the cytotoxic and antioxidant activities of the fruit and fruit waste (residue and marc) extracts of Antidesma thwaitesianum Müll. Arg., known as mamao in Thai, using chemical and cell-based assays. Methods: The cytotoxicity of mamao fruit and fruit waste extracts obtained by expression, maceration and decoction against a panel of six human cancer cell lines (COR-L23, A5...

La guerre en Ukraine bouleverse la scène énergétique européenne et sa relation de dépendance à Russie. Cet article analyse les enjeux défis, pour l’Europe, du conflit russo-ukrainien sur le marché gazier. Il met d’abord évidence l’évolution l’ampleur des économies européennes au gaz russe discute impacts éc...

By applying the dimensional analysis approach to a lab-scale stirred tank process, influence of process parameters on foamability three model surfactants: SLES, Tween 20 and Brij L23 is investigated modelled. For validation law, theoretical complemented with an experimental work varying such as agitator rotational speed rate (N), mixing time (tm) bottom clearance (Cb). The foam expansion surfac...

Lumbar vertebrae are complicated in structure and function. The purpose of this study was to investigate the in-vivo motion characteristics of different portions of the lumbar vertebrae during functional activities. Motion of L2, L3 and L4 was reproduced using a combined dual fluoroscopic and MR imaging technique during flexion-extension and left-right twisting of the trunk. The ranges of motio...

Amaranthus species are of underutilized orphan crops grown in tropical and sub-tropical regions the world. Benin’s most appreciated cruentus L. «local» cultivar is susceptible to saline stress. This study aimed create genotypes agronomically, at least, as good useful for further tolerance breeding using mutation breeding. The morphological diversity among 19 gamma-irradiated A. mutant lines (co...

The article suggests that the emergence of FabLabs and other collaborative spaces innovation imply new modes manufacturing, based on a more social, inclusive, open approach than current industrial mass-production models. We argue are platforms social allowing different combinations interactions between industries individuals, through their activities around making (producing goods from raw mate...
