High-pressure X-ray diffraction was carried out on a single crystal of gypsum compressed in a diamond anvil cell. The sample maintained its crystal structure up to 4.0 ± 0.1 GPa. The fit of pressure dependence of the unit-cell volume to the third-order Birch-Murnaghan equation yielded KT0 = 44(3) GPa and (∂KT/∂P)0 = 3.3(3), where KT0 and (∂KT/∂P)0 are the isothermal bulk modulus and its pressur...

INTRODUCTION Granulomatosis with polyangiitis (GPA) is a necrotising vasculitis of small arteries and veins. In its classical manifestation GPA affects the upper and lower respiratory tract and kidneys. However, other organs, including those of the gastrointestinal tract, may be affected as well. AIM To present the clinical manifestations of gastrointestinal tract involvement in patients with...

We demonstrate that the compressibility of cubic fluorite-structure CeO2 nanocrystals s10 nmd increases at pressures above ,20 GPa. At ambient pressure, CeO2 nanocrystals exhibit larger cell parameters than micro-sized samples, and initially exhibit a higher bulk modulus of 328s12d GPa. However, above 20 GPa, the bulk modulus is reduced to 230s10d GPa. Thus, a critical pressure of ,20 GPa was d...

Cyanuric triazide (CTA), a nitrogen-rich energetic material, was compressed in a diamond anvil cell up to 63.2 GPa. Samples were characterized by x-ray diffraction, Raman, and infrared spectroscopy. A phase transition occurring between 29.8 and 30.7 GPa was found by all three techniques. The bulk modulus and its pressure derivative of the low pressure phase were determined by fitting the 300 K ...

INTRODUCTION In autoimmune diseases, IL-17 producing T-cells (Th17), a pro-inflammatory subset of T-cells, are pathophysiologically involved. There is little knowledge on the role of Th17 cells in granulomatosis with polyangiitis (GPA). In the present study, we investigated Th17 cells, Tregs and subsets of circulating Th17 cells in GPA and related results to disease activity. METHODS 42 GPA p...

Objectives. This study was designed to assess the extent to which 7 traditional and novel predictors contribute to overall pharmacy grade point average (pharmacy GPA), first through third year pharmacy GPA (1-3 year GPA), and clerkship GPA of pharmacy students. Methods. This investigation used a convenience sample and a blinded retrospective record review of the first 3 class years of Doctor of...

The Arabidopsis (Arabidopsis thaliana) lipase-like protein PHYTOALEXIN DEFICIENT4 (PAD4) is essential for defense against green peach aphid (GPA; Myzus persicae) and the pathogens Pseudomonas syringae and Hyaloperonospora arabidopsidis. In basal resistance to virulent strains of P. syringae and H. arabidopsidis, PAD4 functions together with its interacting partner ENHANCED DISEASE SUSCEPTIBILIT...

This study involves an exploratory examination of the effects of a 12-week school-based yoga intervention on changes in grade point average (GPA) in 9th and 10th grade students. Participants included 95 high school students who had registered for physical education (PE) in spring 2010. PE class sections were group randomized to receive either a yoga intervention or a PE-as-usual control conditi...

23 Synchrotron X-ray powder diffraction and infrared (IR) spectroscopy studies on 24 natural brucite were conducted up to 31 GPa using diamond anvil cell (DAC) techniques 25 at beamlines X17C and U2A of National Synchrotron Light Source (NSLS). The lattice 26 parameters and unit-cell volumes were refined in m1 3 P − space group throughout the 27 experimental pressure range. The anisotropy of la...

The numerical coefficients linearly relating the effects of stress (including pressure), temperature, and composition to shifts in the energies of the Cr-related fluorescence in alumina (Al2O3) are reviewed. The primary focus is the shift of the R1 and R2 “ruby” fluorescence lines under conditions typical for stress determination in polycrystalline Al2O3. No significant experimental difference ...
