Effectiveness of BFRP confinement on the compressive behaviour of clay brick masonry cylinders
2020
Abstract This paper presents the results of an experimental and analytical study on the compressive behaviour of small clay brick masonry cylinders reinforced with a basalt fibre reinforced polymer (BFRP) composite. Fourteen cylinders, manufactured using two assembling schemes and confined using either one or two layers of BFRP grids, were tested under monotonic compression loading. Traditional strain measuring systems were integrated with digital image correlation (DIC) technique. The BFRP confined masonry cylinders showed a ductile behaviour characterised by a softening branch of the stress–strain curve. The experimental strains, strength, and full stress–strain curves were modelled using…
El coneixement i l'ús de les aplicacions educatives dels estudiants universitaris d'Espanya i la República Txeca
2020
Technological evolution has led to many changes at both professional and academic levels. The inclusion of Information and Communication Technologies (ICT) has caused dizzying changes in the different contexts of life (educational, professional, social). More and more applications are being downloaded by users to their mobile devices, both for entertainment and training. For this reason, this study is based on the need to assess the knowledge and attitude of university students towards downloading existing educational applications. In this way, the use and frequency of these tools in the teaching-learning process of the students will be analyzed. In order to carry out this study, the quanti…
The Processing of Medical Images: Principles, Main Applications and Perspectives
2013
This chapter provides an introduction to the basic concepts of medical digital image processing. We kept the mathematical complexity of the chapter at a low level so that life science students can understand the underlying principles behind the methods of analysis and computer-assisted diagnosis.
DIGITAL MAPPING E GIUSTIZIA SOCIALE
2014
La rappresentazione del territorio ha molteplici significati ed è espressione di una particolare visione del luogo vissuto; coinvolge dunque il tema della partecipazione al processo di pianificazione. L’immagine urbana e gli strumenti attraverso i quali viene costruita sono alla base delle dinamiche di governo delle città e dei territori, e la complessità di tali meccanismi è amplificata dalla diffusione della tecnologia informatica applicata alla cartografia (GIS, webGIS) e da fenomeni di trasformazione sociale, economica e culturale (globalizzazione). Si rende dunque necessaria la costruzione di nuovi strumenti di rappresentazione adeguatamente inclusivi dei diversi punti di vista attrave…
Digital image processing for rapid analysis of differentially expressed transcripts on high-density cDNA arrays.
1999
Usage of filter arrays is becoming increasingly attractive for many research laboratories involved in determination of gene-expression profiles. However, analysis of numerous spots, representing genes or partial gene sequences (ESTs), is still tedious work involving the ordered analysis of vast amounts of numerical tabular data. We present a rapid and efficient method for the visual identification of differentially expressed targets on high-density cDNA filter arrays using standard laboratory equipment and standard software, which is available for free. The method we introduce provides an inexpensive alternative, and no changes in the experimental set up are required. Our results were veri…
Plant progesterone 5β-reductase is not homologous to the animal enzyme. Molecular evolutionary characterization of P5βR from Digitalis purpurea
2007
Plants of the genus Digitalis produce cardiac glycosides, i.e. digoxin, which are widely used for congestive heart failure. Progesterone 5beta-reductase (P5betaR) is a key enzyme in the biosynthesis of these natural products. Here, we have carried out the purification and partial amino acid sequencing of the native P5betaR from foxglove (Digitalis purpurea), and isolated a cDNA encoding this enzyme. Similarly to other steroid 5beta-reductases, the recombinant P5betaR catalyzes the stereospecific reduction of the Delta(4)-double bond of several steroids with a 3-oxo,Delta(4,5) structure. The gene encoding P5betaR is expressed in all plant organs, and maximally transcribed in leaves and matur…

Digital holographic microscopy with pure-optical spherical phase compensation
2011
Telecentric architecture is proposed for circumventing, by the pure-optical method, the residual parabolic phase distortion inherent to standard configuration of digital holographic microscopy. This optical circumvention produces several important advantages. One is that there is no need for computer compensation of the parabolic phase during the phase map recovering procedure. The other is that in off-axis configuration, the spatial frequency useful domain is enlarged. The validity of the method is demonstrated by performing quantitative measurement of depth differences with high axial resolution. (C) 2011 Optical Society of America

Digitālo prasmju pilnveides iespējas dabaszinību stundā 4. klasē
2019
Mūsdienās pasaule ir raksturota ar globalizācijas, informācijas tehnoloģiju attīstību un vērtību daudzveidību. Izglītības digitalizācijas kontekstā skolēnu digitālas prasmes kļūst arvien nozīmīgākas. Digitālas tehnoloģijas nodrošina starpdisciplinārs domāšanas pamatu un sagatavo skolēnus pilnvērtīgai iekļaušanai sabiedrībā un kvalificētus cilvēkus nākotnes darbavietām. Skolēniem tiek veidotas pamata prasmes, tāpēc diplomdarba mērķis ir noskaidrot skolēnu digitālās prasmes un tas pilnveides iespējas izglītības dabaszinību stundās digitalizācijas kontekstā. Analizējot teorētisko literatūru un veicinot pētījumu, secināts, ka 4. klases skolēnu digitālo prasmju līmenis nav pietiekami augsts. Tas…
