We present new low and intermediate-resolution spectroscopic observations of the Wolf Rayet (WR) star population in the massive starburst cluster Westerlund 1. Finding charts are presented for five new WRs – four WNL and one WCL – raising the current total of known WRs in the cluster to 19. We also present new spectra and correct identifications for the majority of the 14 WR stars previously kn...

The use of cosmogenic nuclide dating methods place in doubt the long-term future of weathering rinds (WRs) as a chronometric tool. Why estimate ages when radiometric control is possible? This paper presents evidence that WRs can provide invaluable clues about what particular sample would provide the most accurate cosmogenic age by avoiding binheritanceQ of cosmogenic nuclides and by avoiding bo...

Wolcott-Rallison syndrome (WRS) is a rare autosomal recessive disorder characterized by the association of permanent neonatal or early-infancy insulin-dependent diabetes, multiple epiphyseal dysplasia and growth retardation, and other variable multisystem clinical manifestations. In the present study, we analyzed the EIF2AK3 gene in a 64 day-old-girl WRS patient and his parents to study the cli...

The objective of this research is to systematically understand how strain-hardening models and phase- temperature-dependent slopes affect the computed residual stresses in single-pass welded joints made widely used structural steel S235. Both experimental methods numerical simulation have been utilized for investigation. results reveal that material plasticity model has a massive effect on pred...

In this paper, the effect of Welding Residual Stress (WRS) on size and morphology hydrogen-induced cracks (HIC) is studied. Four samples were manufactured using a 6-axis welding robot in two separate batches. The difference between batches was clamping system used, which resulted different amounts deformation WRS. hydrogen intentionally localised water-quenching method, where water sprayed over...

Angiotensin-(1-7) [Ang-(1-7)] is a major vasoactive metabolite of angiotensin I (Ang I), both being important components of the renin-angiotensin system (RAS). Ang-(1-7) acting via Mas receptor was documented in kidneys, heart, brain, and gastrointestinal (GI)-tract. We studied the gastroprotective activity of exogenous Ang-(1-7) in rats exposed to water immersion and restraint stress (WRS) wit...

[1] Previous studies have shown strong contrasting trends in annual sea ice duration and in monthly sea ice concentration in two regions of the Southern Ocean: decreases in the western Antarctic Peninsula/southern Bellingshausen Sea (wAP/sBS) region and increases in the western Ross Sea (wRS) region. To better understand the evolution of these regional sea ice trends, we utilize the full tempor...

early-onset diabetes, liver dysfunction, growth retardation, spondyloepiphyseal dysplasia, and tendency to skeletal fractures due to osteopenia are characteristics of wolcott-rallison syndrome (wrs). eukaryotic translation initiation factor 2α kinase (eif2ak3) is the only known gene, which is responsible for this rare autosomal recessive disorder. here, we report two siblings a girl and a boy w...

Variants at 21 genetic loci have been associated with an increased risk for Alzheimer's disease (AD). An important unresolved question is whether multiple genetic risk factors can be combined to increase the power to detect changes in neuroimaging biomarkers for AD. We acquired high-resolution structural images of the hippocampus in 66 healthy, older human subjects. For 45 of these subjects, lo...
