A Proposed Failure Mechanism for Pulp Fiber-Fiber Joints

BioResources, 2016
Due to stress concentration at the edges, fiber-fiber bonds under load are known to fail gradually inwards from the edges. In this paper, we propose a failure mechanism for fiber-fiber joints under load, based on the peak stresses occurring at the bond ...

The Effect of a 7-Week Training Period on Changes in Skin NADH Fluorescence in Highly Trained Athletes

Applied Sciences, 2020
The study aimed to evaluate the changes of nicotinamide adenine dinucleotide (NADH) fluorescence in the reduced form in the superficial skin layer, resulting from a 7-week training period in highly trained competitive athletes (n = 41).

Body symmetry and physical strength in human males

American Journal of Human Biology, 2014
ObjectivesBody symmetry and physical strength in males have been related to aspects of mate “quality”—women seem to prefer men who display both “good genes” (as indexed by high symmetry/developmental health) and fighting ability (as indexed by physical strength).

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

The effects of inspiratory muscle training in older adults [PDF]

, 2015
Purpose: Declining inspiratory muscle function and structure and systemic low-level inflammation and oxidative stress may contribute to morbidity and mortality during normal ageing.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Novel classical ground state of a many body system in arbitrary dimensions

, 1998
The classical ground state of a D- dimensional many body system with two and three body interactions is studied as a function of the strength of the three body interaction.

Dynamic strength of rocks and physical nature of rock strength

Journal of Rock Mechanics and Geotechnical Engineering, 2009
Abstract:Time-dependence of rock deformation and fracturing is often ignored. However, the consideration of the time-dependence is essential to the study of the deformation and fracturing processes of materials, especially for those subject to strong dynamic loadings.
