Advanced Engineering Materials, EarlyView.High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Systèmes durables avec minimum d'intrants à Madagascar : semis direct sur couverture végétale permanente avec écobuage [PDF]
, 2007 Sur les Hautes-Terres de Madagascar, la pression démographique accélère la mise en culture des collines aux sols fragiles et peu fertiles. Les fumures étant limitées, les rendements restent faibles.

Advanced Engineering Materials, EarlyView.The growing demand for lightweight, nontoxic, and multifunctional gamma shielding materials has intensified efforts to find alternatives to conventional lead and aluminum‐based protectants. In this work, we develop epoxy quartz fabric composites reinforced with cobalt chloride (CoCl2) microparticles, fabricated via hand lay‐up with varying filler ...

Advanced Engineering Materials, EarlyView.Creep experiments at 900°C on coarse‐grained steel‐ceramic composites containing recycled magnesia reveal that higher ceramic volume fractions significantly enhance the creep resistance. Detailed EBSD investigations identify subgrain formation in the steel matrix as the dominant deformation mechanism.

Analyse du fonctionnement biologique du sol par l'étude de la nématofaune : semis direct versus labour sur les hautes terres près d'Antsirabé (Madagascar) [PDF]
, 2009 International audienceLes nématodes du sol possèdent des qualités multiples (abondance, diversité taxonomique et fonctionnelle, existence d'indices liés à l'état du sol) qui en font des indicateurs pertinents du fonctionnement du sol.

Geometric properties of Lagrangian mechanical systems
, 2006 The geometry of a Lagrangian mechanical system is determined by its associated evolution semispray. We uniquely determine this semispray using the symplectic structure and the energy of the Lagrange space and the external force field.

Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures
Advanced Engineering Materials, EarlyView.This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Free resolutions for semi-direct products
Tohoku Mathematical Journal, 1993 We define a notion of one group acting on a free resolution for another and show how this can lead to a free resolution for the semi-direct product. We apply this result to obtain a free resolution for dihedral groups.
