Investigation of metal flow in bridge die extrusion of Alloy 6063 and subsequent effect on surface quality and weld seam integrity [PDF]
, 2013 This paper describes a detailed study of tube extrusion by simulation using finite element method (FEM). The finite element model used one-sixth of symmetry. The extrusion load, emperature evolution and metal flow were predicted.

Effect of process parameters on the properties of LDPE/sepiolite composites
PolímerosThis study examines the effect of processing parameters and reactive extrusion on the mechanical, thermal, morphological, and rheological properties of low-density polyethylene (LDPE) and sepiolite composites (LDPE/sepiolite: 95/5 wt/wt) produced by in ...

A study on surface cracking in extrusion of aluminium alloy AA2014 [PDF]
, 2004 Surface cracking is generally recognised as one of the main defects occurring during the process of aluminium extrusion, especially in the case of the so called hard aluminium alloys.

The effect of pressure and temperature variations on the FEM prediction of deformation during extrusion [PDF]
, 2005 The extrusion process is complex, involving interaction between the process variables and the material’s high temperature properties and is typically conducted at relatively high temperatures because the lower flow stress of the material permits larger ...

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer
Molecular Oncology, EarlyView.Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

GelMA‐based 3D spheroids recapitulate transcriptomic and functional hallmarks of myeloid sarcoma
FEBS Open Bio, EarlyView.GelMA 5% hydrogels support the formation of myeloid leukemia spheroids that recapitulate MS‐specific features, including G1 arrest, apoptosis, and ECM‐driven transcriptomic reprogramming. The 3D model mimicked soft‐tissue‐like stiffness and oxygen conditions, and transcriptomic convergence with primary MS samples confirmed its utility as a preclinical ...

Study of the compatibilizer effect in the properties of starch/polyester blends [PDF]
Polímeros, 2013 The mechanical, viscoelastic and structural properties of starch/ poly (butylene adipate co-terephthalate) (PBAT) blown films produced by reactive extrusion were evaluated using citric acid (CA) and maleic anhydride (MA) as compatibilizers.
