Adaptive Hypermedia (AEH) is considered, in principle, superior to regular Hypermedia, due to the fact that it allows personalization and customization. However, the creation of good quality AEH is not trivial. Nowadays, a lot of research concentrates on the authoring challenge in adaptive hypermedia. We previously introduced the LAOS model, a five-layer adaptive hypermedia authoring model that...

The structure of near-wall layers has been the subject of much research over many years, with conceptual descriptions of the Attached Eddy Hypothesis (AEH, henceforth) by Townsend (1980) and Perry & Chong (1982) being key historical fix points. The fact that major efforts have continued unabated over the past two to three decades reflects the exceptional structural complexity of near-wall layer...

The AEH follows a successful series of workshops on Adaptive and Adaptable Educational Hypermedia. This workshop focuses on models, design and authoring of AEH, on assessment of AEH, conversion between AEH and evaluation of AEH. The workshop has paper presentations, poster session and panel discussions. As you see, we have a full agenda, so don’t hesitate to join us! Introduction This workshop ...

Wastes generated during the cultivation of marine microalga Crypthecodinium cohnii and after lipid extraction process, were energetically valorized into biogas production through anaerobic digestion (AD). The tested wastes extracted microalgae (Ae) with hexane (AeH) using supercritical methods (AeS) supernatant obtained culture medium centrifugation (M). algae biomass in admixture (AeH+M+I AeS+...

BACKGROUND Although men who have sex with men (MSM) represent a dominant risk group for human immunodeficiency virus (HIV), the risk of HIV infection within this population is not uniform. The objective of this study was to develop and validate a score to estimate incident HIV infection risk. METHODS Adult MSM who were tested for acute and early HIV (AEH) between 2008 and 2014 were retrospect...

When it comes to covering the growing demand for cooling power worldwide, elastocalorics offer an environmentally friendly alternative compressor-based technology. The absence of harmful and flammable coolants makes suitable energy applications such as battery cooling. Initial prototypes elastocaloric systems, which transport heat by means thermal conduction or convection, have already been dev...

OBJECTIVE The aim of our study is to determine clinical factors and sonographic findings associated with endometrial hyperplasia or cancer (EH+) in premenopausal and perimenopausal women. METHODS A total of 14,340 transvaginal ultrasonography examinations of 9,888 healthy premenopausal and perimenopausal women were included in this retrospective study. One hundred sixty-two subjects underwent...

Hemicelluloses are abundant polysaccharides in the plant cell walls. They tether the celulose microfibrils and participate in the control of the cell expansion together with expansins (Cosgrove, 1998) [1]. The hemicellulose may present a variety of decorating side chains, including feruloyl and acetyl substituents. The ferulic acid may be esterified to the hemicellulose and crosslinked to ligni...

Alpha-amino acid ester hydrolase (EC 3.1.1.43, AEH) is a promising biocatalyst for the production of semi-synthetic β-lactam antibiotics, penicillins and cephalosporins. The AEH gene from Xanthomonas rubrilineans (XrAEH) was recently cloned in this laboratory. The three-dimensional structure of XrAEH was simulated using the homology modeling method for rational design experiments. The analysis ...
