Defining ‘forced migration’ in Burma [PDF]

open access: yesForced Migration Review, 2008
Most Burmese people fleeing their homes do so for a combination of reasons. The root causes for leaving, however,determine which ‘category’ they belong to: ‘internally displaced persons’ (IDPs) or ‘economic migrants’.

Catástrofes creadas y su invisibilización en los contextos urbanos: la migración forzada al interior de las ciudades en Colombia

open access: yesBulletin de l'Institut Français d'Études Andines, 2014
The change in the logic of Colombian armed conflict —scenes, objectives, actors and warlike strategies— has made forced migration evolve in such a way that it is not possible now to talk only about forced migration from rural environments to urban ones ...

Pipe Poiseuille flow of viscously anisotropic, partially molten rock [PDF]

open access: yes, 2014
Laboratory experiments in which synthetic, partially molten rock is subjected to forced deformation provide a context for testing hypotheses about the dynamics and rheology of the mantle.

Impact of Hot Isostatic Pressing on Microstructure Evolution and Creep Performance of Powder Bed Fusion–Laser Beam Processed CM247LC

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of Hot Isostatic Pressing (HIP) temperature on the microstructure and creep performance of powder bed fusion–laser beam processed CM247LC superalloy is investigated. Grain growth and γ’ precipitate evolution are characterized following HIP at varying temperatures.

The Structural Refinement of Commercial‐Purity Copper Processed by Equal Channel Angular Pressing with Low Strain Amplitude

open access: yesAdvanced Engineering Materials, EarlyView.
Equal channel angular pressing of commercial pure copper under low strain amplitude (≈0.48) induces concurrent continuous and localized discontinuous dynamic recrystallization, forming a duplex structure influenced by strain heterogeneity and recovery. Moderate hardening after 4–12 passes results from progressive high‐angle grain boundary formation via

Microcellular Poly (Ethylene‐Co‐Vinyl Acetate)/Lignin Nanocomposites for Soft Ferroelectrets

open access: yesAdvanced Engineering Materials, EarlyView.
Lignin valorization for advanced porous polymer nanocomposites development and an upscaling route for continuous manufacturing of soft ferroelectrets for energy harvesting are studied. This work examines the role of lignin and carbon nanotubes (CNT) in modifying the mechanical, dielectric, and ferroelectret properties of poly (ethylene‐co‐vinyl acetate)

Glycodelin suppresses endometrial cell migration and invasion but stimulates spheroid attachment [PDF]

open access: yes, 2012
Glycodelin contains four isoforms with diverse biological functions. Glycodelin-A is potentially a diagnostic marker for cancer patients and receptivity marker of the secretory endometrium.

Adjustment of Coatings Morphology and Particle Distribution of Layered Silicates by Freeze‐Drying for Improved Gas Barriers

open access: yesAdvanced Engineering Materials, EarlyView.
Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...
