Charge transport properties in close-packed nanoparticle arrays with thickness crossing over from two dimensions to three dimensions have been studied. The dimensionality transition of nanoparticle arrays was realized by continually printing spatially well-defined nanoparticle monolayers on top of the device in situ. The evolution of charge transport properties depending on the dimensionality h...

This paper investigates the possibility for iron fortification of food using a new preparation method for protein gel particles in which iron is entrapped in the presence of ascorbate using cold-set gelation. The effect of ascorbate on the iron-induced cold-set gelation process of whey protein was studied in order to optimize the ratio of iron/ascorbate. Subsequently, the effect of ascorbate on...

Two important design aspects encountered in IGBT press pack modules used for HVDC applications are short circuit failure mode (SCFM) and intermittent operating life (IOL) capabilities. The requirement that press-pack IGBT (PPI) fail safely into a short causes a design conflict with the module’s desired capability to survive a high number of power cycles in normal operation. An innovative materi...

Higher exacerbation incidence rates in chronic obstructive pulmonary disease (COPD) are associated with more rapid decline in lung function and poorer quality of life, yet the mechanisms determining susceptibility to exacerbation remain ill-defined. The same viruses responsible for common colds are frequently isolated during exacerbations. The current authors hypothesised that exacerbation freq...

Since the publication of one of the first studies using 2D gel electrophoresis by Patrick H. O'Farrell in 1975, several other studies have used that method to evaluate cellular responses to different physicochemical variations. In environmental microbiology, bacterial adaptation to cold environments is a "hot topic" because of its application in biotechnological processes. As in other fields, g...

Cardiovascular events are more common in the winter months, possibly because of hemodynamic alterations in response to cold exposure. The purpose of this study was to determine the effect of acute facial cooling on central aortic pressure, arterial stiffness, and wave reflection. Twelve healthy subjects (age 23 +/- 3 yr; 6 men, 6 women) underwent supine measurements of carotid-femoral pulse wav...

Isoelectric Focusing in Immobilized pH Gradient Strips Using the IPGphor Unit: Sample In-Gel Rehydration Angelika Görg, Oliver Drews, and Walter Weiss This protocol was adapted from "IEF in IPG Strips Using the IPGphor Unit," contributed by Angelika Görg, Oliver Drews, and Walter Weiss, Chapter 16, in Purifying Proteins for Proteomics (ed. Simpson). Cold Spring Harbor Laboratory Press, Cold Spr...

Objectives: It is well known that neuromuscular function is temperature sensitive. Changing of muscle temperature can effect voluntary muscle contraction. The aim of this study was to investigate the effects of cooling and heating on maximal isometric force generated by the elbow flexor musculature in male subjects. Methods: Forty five healthy males encompassing 3 groups participated in the ...

An excess Gibbs free energy model is applied to in®estigate the influence of n-paraffin composition on the aging beha®ior of wax-oil gel deposits known to form in subsea petroleum transport pipelines. The aging of wax-oil gels occurs by a counterdiffusion process where wax molecules with carbon numbers greater than a critical carbon num( ) ber CCN diffuse into the gel matrix, and ®ice ®ersa. Mo...

Docking the tails of dairy cattle causes mild to moderate behavior changes and physiological indicators of acute pain, but no studies have investigated the possibility that tail docking may lead to chronic pain. In human amputees, an incidence of increased limb surface temperature is associated with phantom limb pain, a central nervous system representation that survives peripheral loss. The ob...
