A study of the wear process related to twin-screw extruders [PDF]

, 1996
Extruders are used in a wide range of process industries and high reliability is essential if cost effective manufacturing is to be maintained. A critical part of twin-screw extruders is the barrel that must withstand many different wear and corrosion ...

Some thoughts on neural network modelling of micro-abrasion-corrosion processes [PDF]

, 2008
There is increasing interest in the interactions of microabrasion, involving small particles of less than 10 μm in size, with corrosion. This is because such interactions occur in many environments ranging from the offshore to health care sectors.

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Some remarks on particle size effects on the abrasion of a range of Fe based alloys

, 2010
The low-stress three body abrasion behaviour of a range of steels was investigated. The tests were carried out in a rubber wheel tester (according to ASTM G65-94, reapproved in 2000) at room temperature.

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

Molecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

Abrasive wear with particular reference to digger teeth [PDF]

, 1987
This thesis was submitted for the degree of Doctor of Philosophy and was awarded by Brunel University.Abrasive wear occurs when a contact associated with stress between a metal surface and a herd particle (frequently of mineral origin) leads to ...

Effect of a combined machining/burnishing tool on the roughness and mechanical properties [PDF]

, 2014
Burnishing is a cold working surface treatment process in which plastic deformation of surface irregularities occurs by exerting pressure through a very hard and a very smooth roller or ball on a surface to generate a uniform and work-hardened surface ...

CHANGING BARREL SURFACE MACROGEOMETRY THROUGH VIBROFINISHING TREATMENT ON FLAT OSCILLATING SURFACE

Advanced Engineering Research, 2011
The experimental results of barrel vibrofinishing (grinding-in) through rolling on the flat oscillating surface are presented. The given method is nonconventional, and it includes both finishing methods and vibrotransportation.

CD47 promotes mitogen‐activated protein kinase and epithelial‐to‐mesenchymal transition molecular programs to drive prometastatic phenotypes in non‐small cell lung cancer

Molecular Oncology, EarlyView.
Beyond its role in immune evasion, this study identified that CD47 drives tumor‐intrinsic signaling in non‐small cell lung cancer (NSCLC). Transcriptomic profiling and functional studies revealed that CD47 regulates cell adhesion, migration, and metastasis through an ERK–EMT signaling axis.

Surface integrity and process simulation in abrasive flow machining

, 2022
S.608-619Trends like lightweight construction and functional integration lead to more and more complex workpieces. Often, these workpieces have to be finished after machining. Especially inner contours are difficult to finish.
