Basal Glucose on Tolerance Test During Pregnancy Predicts Impaired Fasting Glucose and Type 2 Diabetes Within 2 Months A...

Published in Canadian journal of diabetes

Postpartum mothers with gestational diabetes may remain with either type 2 diabetes mellitus, impaired glucose tolerance or impaired fasting glucose. Our aim in this study was to identify maternal variables that could predict 1 or more of these conditions. In 193 singleton pregnancies with gestational diabetes, we applied bivariate logistic regress...

Entre b-a-ba et mathématique euclidienne : les empreintes de l’enseignement scolaire dans "La Fontegara" de Silvestro Ga...

Le contenu comme la présentation de "La Fontegara" (1535) attestent la grande cohérence du projet de son auteur, Silvestro Ganassi. Cependant, une lecture de ce traité informée par les usages scolaires de la première moitié du XVIe siècle conduit à y déceler des influences contrastées. "La Fontegara" entre effectivement en résonance avec des procéd...

MDCTA diagnosis of cerebral vessel disease among patients with arterial hypertension.

Published in Polish journal of radiology / Polish Medical Society of Radiology

MDCT angiography is a highly informative method to study changes of cerebral vessels in patients with hypertension. The relationship between changes in cerebral blood vessels diagnosed through MDCT angiography and the level of total cardiovascular risk among patients with hypertension had been established.

Effect of high temperature AlGaN buffer thickness on GaN Epilayer grown on Si(111) substrates

Crack-free GaN epitaxial layer was obtained through inserting 80 nm graded AlGaN buffer layer between GaN epilayer and high temperature AlN buffer on 2-in Si(111) substrates by metal organic chemical vapor deposition. This paper investigated the influence of AlGaN buffer thickness on the structural properties of the GaN epilayer. It was confirmed f...

Quantitative surface enhanced Raman scattering detection based on the "sandwich" structure substrate

A sandwich structured substrate was designed for quantitative molecular detection using surface enhanced Raman scattering (SERS), in which the probe molecule was sandwiched between silver nanoparticles (SNPs) and silver nanoarrays. The SNPs was prepared using Lee-Meisel method, and the silver nanoarrays was fabricated on porous anodic aluminum oxid...

Fabrication of biomimic GaAs subwavelength grating structures for broadband and angular-independent antireflection

We combine interferometric lithography and inductively coupled plasma etching to fabricate GaAs subwavelength grating (SWG) which mimics the moth eye structures. Through the modification of morphology parameters, including profile, height and packing fraction, tapered, high-aspect-ratio and closely-packed GaAs SWGs are obtained. The measurement of ...

Effects of AlGaN/AlN Stacked Interlayers on GaN Growth on Si (111)

We report the growth of high quality and crack-free GaN film on Si (111) substrate using Al0.2Ga0.8N/AlN stacked interlayers. Compared with the previously used single AlN interlayer, the AlGaN/AlN stacked interlayers can more effectively reduce the tensile stress inside the GaN layer. The cross-sectional TEM image reveals the bending and annihilati...

Wavelength Coded Optical Time-Domain Reflectometry

This paper presents a wavelength coded optical timedomain reflectometry based on optical heterodyne technique. In this scheme, the probe and reference optical pulses have different wavelengths. This enables optical heterodyne detection to be used to improve the system performances significantly. We demonstrate a spatial resolution of 2.5 m within a...
