Deterioration Law of Mechanical Properties of Insulation Pressboard Under Multifield Coupled Ageing

High Voltage, EarlyView.
ABSTRACT Converter transformers can experience progressive deterioration of their oil–pressboard insulation under elevated temperature, combined AC–DC electrical stress and persistent mechanical vibration. This study investigates how mechanical vibration affects the mechanical properties of insulation pressboard and clarifies the associated microscopic

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Microfibril angle and density patterns of fertilized and irrigated Norway spruce

Silva Fennica, 2004
Two Norway spruce nutrient optimisation trials, one in the north of Sweden and one in the south, were used to study the effects of intensive growth and fertilization on wood density and microfibril angle.

The role of calcium in the organization of fibrillin microfibrils

FEBS Letters, 1993
The microfibrillar glycoprotein fibrillin has a multidomain structure which contains forty‐three epidermal growth factor‐like motifs with calciumbinding consensus sequences. We have utilized intact microfibrils isolated from human dermal fibroblast cultures to investigate the putative influence of bound calcium on microfibrillar organization and ...

The plasticisation model of dye diffusion: Part 7

Coloration Technology, EarlyView.
Abstract Re‐evaluation using the Williams‐Landel‐Ferry equation, of exhaustion/fixation/adsorption data previously reported for four classes of anionic dye onto three different types of wool substrate, revealed that thermally activated dyeing/desorption behaviour is governed by the thermally regulated structural relaxation times of the respective water‐

A study of the nanostructure of the cell wall of the tracheids of conifer xylem by x-ray scattering [PDF]

, 2007
The purpose of this study was to develop practical and reliable x-ray scattering methods to study the nanostructure of the wood cell wall and to use these methods to systematically study the nanostructure of Norway spruce and Scots pine grown in Finland ...

Structure of the Fibrillin-1 N-Terminal Domains Suggests that Heparan Sulfate Regulates the Early Stages of Microfibril Assembly

Structure, 2013
Summary The human extracellular matrix glycoprotein fibrillin-1 is the primary component of the 10- to 12-nm-diameter microfibrils, which perform key structural and regulatory roles in connective tissues.

Proteolysis at the extracellular matrix interface: Molecular architects and regulators in health and disease

The FEBS Journal, EarlyView.
The extracellular matrix (ECM) is a dynamic scaffold that orchestrates tissue architecture and cellular communication. A critical but underexplored interplay between proteases and cluster of differentiation molecules (CD) governs ECM turnover and directs cell fate.
