Experimental Study of Soil Texture and Cross River Structures on Depth of Undercutting Hole Induced by Seepage Erosion in River Banks [PDF]

علوم و مهندسی آبیاری, 2012
Despite of many researches on bank erosion mechanism, there exists an incomplete understanding of one of the basic mechanisms governing sediment loading to streams which is namely erosion by concentrated lateral, subsurface flow which causes river bank ...

J-integral evaluation methods for cylinders with multiple circumferential cracks subjected to bending moments

Mechanical Engineering Journal, 2018
This paper describes the J-integral evaluation methods for the case of multiple circumferential cracks in a cylinder subjected to bending moments. J-integral is one of the parameters of fracture mechanics used in the fracture assessment of materials that

The subcellular distribution of phosphorylated Y‐box‐binding protein‐1 at S102 in colorectal cancer patients, stratified by KRAS mutational status and clinicopathological features

Molecular Oncology, EarlyView.
This study identifies nuclear YB‐1 S102 phosphorylation as a marker associated with KRAS and FBXW7 mutations in colorectal cancer. Mutated KRAS correlates specifically with nuclear, not cytoplasmic, S102 YB‐1. These findings provide the first ex vivo evidence of this link in CRC and suggest future studies should assess the prognostic and therapeutic ...

Cytomegalovirus infection is common in prostate cancer and antiviral therapies inhibit progression in disease models

Molecular Oncology, EarlyView.
Human cytomegalovirus infection is common in normal prostate epithelium, prostate tumor tissue, and prostate cancer cell lines. CMV promotes cell survival, proliferation, and androgen receptor signaling. Anti‐CMV pharmaceutical compounds in clinical use inhibited cell expansion in prostate cancer models in vitro and in vivo, motivating investigation ...

Impression creep testing across a heat affected zone

Ubiquity Proceedings, 2018
Impression creep testing was applied for studying the creep strain rates in the heat affected zone of a P22 weld in order to support an FE analysis of a piping system. The specimen size recommendations for impression creep were violated in the sense that

CD9‐association with PIP2 areas is regulated by a CD9 salt bridge

FEBS Open Bio, EarlyView.
The tetraspanin CD9 has an intracellular salt bridge. If CD9 opens, open‐CD9 moves from PIP2‐rich areas to regions populated by its interaction partner EWI‐2. Hence, the state of the salt bridge regulates the distribution of CD9 and by this CD9‐EWI‐2 complex formation.

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

Advanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Vacuum‐Formed Composites Based on a Polyolefin and a High Content of Biomass‐Waste Fillers

Advanced Engineering Materials, EarlyView.
It is shown here that by the use of a very ductile polymer matrix, it is possible to vacuum‐form products that contain up to 25% of hard biofillers with still ductile properties. The results are promising and opens up for the use of engineered biocomposites derived from industrial side‐stream biofillers in vacuum‐formed products. A strategy to increase

AVALIAÇÃO DA SUSCEPTIBILIDADE DE SOLOS GNAISSICOS À EROSÃO SUBSUPERFICIAL / Evaluation of piping erosion susceptibility in gnaissic soils [PDF]

Sociedade & Natureza, 2007
The basement rock areas of the Maracujá hydrographic basin show great incidence of hugegullies. This work aims to investigate the influence of the underground erosive processes inthe evolution of these features and to understand how the mineralogical and
