A prestressing procedure is proposed for reduction of stress concentrations at the leading edges of adhesive bondlines in composite skin/ ange assemblies. A Ž niteelementanalysisof a speciŽ c geometryof such an assembly is presented,whichaccounts for nonlinear viscoelastic deformation of the adhesive. Design diagrams based on elastic analysis are constructed for evaluation of prestress forces ...

incorrectly interpreted to be irreversible if only stress-reinjection images were acquired. Dr. Freedman's finding of low differential uptake in 11% of their patients after reinjection appears to confirm our results. We agree with Dr. Freedman that similar information might be obtained if an analysis of thallium activity after a resting injection of 20`T1 were used. Preliminary data in our labo...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014204325 DESCRIPTION A reverse redistribution pattern in rest thallium-201 (Tl)/stress technetium-99 m (Tc) tetrofosmin single photon emission CT (SPECT) is confusing. We present a myocardial perfusion SPECT in a 40-year-old patient undergoing coronary intervention in t...

A 67 years old woman was referred to nuclear medicine center for myocardial perfusion imaging (MPI) for assessment of ischemic heart dieses (IHD).She had a history of atypical chest pain and dyspnea since about 10 days before admission. The MPI SPECT/CT was performed by stress/redistribution Tl-201 protocol. MPI was interpreted as relatively good coronary flow with no appreciable stress induced...

pulse irrigation is consisted of an irrigation phase and a resting or non-operative irrigation phase. water intermittent use causes that advance front with less volume water over continuous irrigation is completed, which it effect on the pattern of soil moisture. another important subject in trickle irrigation is water distribution in non- operative irrigation that called redistribution. amount...

conclusions the results of this work demonstrated that the subcellular distribution of pfdn1 was altered in the rabv-infected n2a cells and colocalized with the n protein of rabv in the nbl structures. results confocal microscopy showed that pfdn1 was colocalized with the n protein of rabv in the infected n2a cells and was mainly recruited to the characteristic negri-body-like (nbl) structures ...

Brain accumulation of the amyloid-β peptide (Aβ) and oxidative stress underlie neuronal dysfunction and memory loss in Alzheimer's disease (AD). Hexokinase (HK), a key glycolytic enzyme, plays important pro-survival roles, reducing mitochondrial reactive oxygen species (ROS) generation and preventing apoptosis in neurons and other cell types. Brain isozyme HKI is mainly associated with mitochon...

A series of physical modeling tests were conducted by means of a beam type geotechnical centrifuge machine in order to investigate the drainage impact on the slope failure mechanism under centrifugal acceleration. Meanwhile, the phenomenon of stress redistribution in undercut slopes and the formation of arching effect were studied. For this purpose, a poorly graded sandy soil (Silica sand No. 6...
