Article Synopsis
- The paper discusses a nondestructive method using energy-resolved neutron imaging to analyze the internal structure and material gradients of different metal-alloy welds, including those made from aluminum to steel and titanium to stainless steel with copper as a filler.
- Neutrons can penetrate thick metals, allowing researchers to study features like internal strain, microstructure, and defects that are not visible with traditional techniques.
- The study shows that this imaging method can provide detailed maps of the weld characteristics, such as texture, voids, and thermal front depth, which can help improve welding processes and material performance.
Neutron scattering from myelin revisited: bilayer asymmetry and water-exchange kinetics.
Acta Crystallogr D Biol Crystallogr
December 2014
Rapid nerve conduction in the central and peripheral nervous systems (CNS and PNS, respectively) of higher vertebrates is brought about by the ensheathment of axons with myelin, a lipid-rich, multilamellar assembly of membranes. The ability of myelin to electrically insulate depends on the regular stacking of these plasma membranes and on the presence of a number of specialized membrane-protein assemblies in the sheath, including the radial component, Schmidt-Lanterman incisures and the axo-glial junctions of the paranodal loops. The disruption of this fine-structure is the basis for many demyelinating neuropathies in the CNS and PNS.

Subjects And Method: Follow-up and re-diagnosis of a highly representative Dutch incidence cohort (N=181), thirty months after first contact with a physician for a psychotic disorder. Poor course was defined as a continuous psychotic illness or a score of less than 39 on the Global Assessment of Functioning scale.
Objective: The purpose of the study was to assess the independent influences of gender and cannabis use on milestones of early course in schizophrenia.
Method: In this population-based, first-contact incidence study conducted in The Hague, the Netherlands, patients (N=133) were interviewed with the Comprehensive Assessment of Symptoms and History, and key informants were interviewed with the Instrument for the Retrospective Assessment of the Onset of Schizophrenia. Milestones of early course were 1) first social and/or occupational dysfunction, 2) first psychotic episode, and 3) first negative symptoms.
Objective: Use of illicit substances has been suggested as an explanation for the increased incidence of psychosis among some immigrant groups. The aim of the present study is to compare the rates of illicit substance use among immigrants with a first psychosis with that among non-migrants.
Method: A population-based, first-contact incidence study in the Netherlands.
