Coupled visco-mechanical and diffusion void growth modelling during composite curing [PDF]

, 2010
Most critical processing step during long fiber reinforced epoxy matrix composite laminate manufacturing is the polymerization stage. If not optimized, it gives birth to defects in the bulk material, such as voids.

Outcomes of Class II composite restorations placed by dental students: An observational study

Saudi Journal of Oral Sciences, 2020
Introduction: Main objectives of restoring the teeth is to remove the caries and replace the tooth structure to restore form and function. This radiographic study aimed to determine the defective Class II composite restorations in permanent teeth placed ...

Influence of manufacturing-induced defects on the fatigue performances of autoclave moulded laminates

Advanced Manufacturing: Polymer & Composites Science, 2021
In the present work, cross-ply and multidirectional laminates were produced by autoclave moulding. Changes in the process parameters led to different microstructural features in terms of fibre volume fraction, global void content, and void size.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Eigen Value Approach in Micropolar Elastic Medium with Voids

International Journal of Applied Mechanics and Engineering, 2013
The eigen value approach, following the Laplace and Hankel transformation has been employed to find a general solution of the field equations in a micropolar elastic medium with voids for an axisymmetric problem.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Moving Loads on Thermo-viscoelastic Micropolar Solid Medium with Voids and Two Temperature [PDF]

Journal of Applied and Computational Mechanics
This work involves the study of the effects of moving loads in an isotropic, homogeneous, micropolar, porous thermo-viscoelastic solid material with two temperatures. The problem is solved in the context of Green-Naghdi theory (G-N II and G-N III).

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.
