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...
Denna uppsats undersöker på vilka sätt fyra professionella blockflöjtister lärde sig att ornamentera inom tidig musik. Fokus ligger på deras utbildningsväg före högskolestudier. Det undersöks vilka olika metoder deras lärare använder sig av och på vilka sätt källstudier från 1500- till 1700-talet spelar en roll inom ramen för deras undervisning.

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.
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...
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...
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 ...
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...
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...

This paper seeks to investigate the impact of Section 18 of the Landlord and Tenant Act 1927 in settlement of dilapidation disputes. This is seen as a developing issue, in current economic conditions. The paper looks at the two limbs of Section 18, and offers practical advice to valuers on preparation of Section 18 valuations. By close analysis of ...
This paper presents a study of the transformation of high-temperature AlN (HT-AlN) interlayer (IL) and its effect on the strain relaxation of Al0.25Ga0.75N/HT-AlN/GaN. The HT-AlN IL capped with Al0.25Ga0.75N transforms into AlGaN IL in which the Al composition increases with the HT-AlN IL thickness while the total Ga content keeps nearly constant. ...
