Jurassic evolution of the Arabian carbonate platform edge in the central Oman Mountains
2005
International audience; The Jurassic Sahtan Group exposed in northern Oman was deposited in shallow marine environments at the edge of the Arabian Platform facing the Neo-Tethys (Hamrat Duru Basin). The upper Sahtan Group is made up of a mixed siliciclastic-carbonate unit overlain by pure carbonate deposits, assigned to a Bathonian and Early Callovian age on the basis of brachiopods and foraminifers. These carbonate depositional systems were composed of outer oolitic shoals that underwent subaerial exposure, and a deeper, somewhat restricted, gently dipping shelf interior. Oolitic material was shed off the platform edge into the deep-sea depositional complex of the Guweyza Formation. The Sa…
Crowdsourced analysis of fungal growth and branching on microfluidic platforms
2021
Fungal hyphal growth and branching are essential traits that allow fungi to spread and proliferate in many environments. This sustained growth is essential for a myriad of applications in health, agriculture, and industry. However, comparisons between different fungi are difficult in the absence of standardized metrics. Here, we used a microfluidic device featuring four different maze patterns to compare the growth velocity and branching frequency of fourteen filamentous fungi. These measurements result from the collective work of several labs in the form of a competition named the “Fungus Olympics.” The competing fungi included five ascomycete species (ten strains total), two basidiomycete…
Astrochronology of the Valanginian stage from GSSP candidates and hypostratotype.
2013
Valanginian; Astrochronology; Gamma-ray spectrometry; Weissert event; Paraná-Etendeka; International audience; The Valanginian Stage currently displays no radiometric age, which severely hampers palaeoceanographic reconstructions for this time interval. An astrochronology of the Valanginian Stage using the stable 405-kyr eccentricity cycle was performed on biostratigraphically well-calibrated standard sections from the Vocontian Basin (southeastern France). High-resolution gamma-ray spectrometry signals were obtained from orbitally driven marl-limestone alternations from five sections in the basin, and they display the same long-term trends. The spectral analyses present the pervasive recor…
A Case Study on Vestibular Sensations in Driving Simulators.
2022
Motion platforms have been used in simulators of all types for several decades. Since it is impossible to reproduce the accelerations of a vehicle without limitations through a physically limited system (platform), it is common to use washout filters and motion cueing algorithms (MCA) to select which accelerations are reproduced and which are not. Despite the time that has passed since their development, most of these algorithms still use the classical washout algorithm. In the use of these MCAs, there is always information that is lost and, if that information is important for the purpose of the simulator (the training simulators), the result obtained by the users of that simulator will no…
Understanding the crowdfunding phenomenon and its implications for sustainability
2019
Abstract Nonetheless the large body of knowledge rapidly accumulated on crowdfunding as well as the growing relevance of this phenomenon for sustainability, there are very few studies on the role of crowdfunding for sustainability-oriented projects, and many related issues are still far from being fully understood. This signalises a clear need for unveiling the main dynamics of the relationship between crowdfunding and sustainability, and also opening up useful directions for future research on this relationship. To conceptualize the implications of crowdfunding for sustainability, we propose and use a framework, encompassing five dimensions, namely the project creator, the backers, the cam…
Kopfinansēšanas iespējas Baltijas Valstīs
2022
Bakalaura darba tēma: Kopfinansēšanas iespējas Baltijas valstīs. Kopfinansēšana tiek uzskatīta par alternatīvu tradicionālajiem finansējuma veidiem. Ar kopfinansēšanas palīdzību fiziskām un juridiskām personām ir iespējams piesaistīt finansējumu, lai realizētu inovatīvas idejas un produktus, finansētu dažādus dzīves apstākļus, kā arī kopfinansēšana ļauj jauni izveidotiem uzņēmumiem piesaistīt pašu kapitālu. Bakalaura darba mērķis: ir izpētīt kopfinansēšanas iespējas Baltijas valstīs, veikt secinājumus un izstrādāt priekšlikumus kopfinansēšanas platformu darbības uzlabošanai. Darbs sastāv no trīs daļām – teorētiskajā daļā tiek apskatīti kopfinansēšanas teorētiskie aspekti – kopfinansēšanas j…
Fracture stratigraphy and oil first migration in Triassic shales, Favignana Island, western Sicily, Italy
2021
This study aims at evaluating the control exerted by fracture stratigraphy and diagenetic processes on oil first migration through an outcropping, mixed carbonate-siliciclastic succession. The present work included results of sedimentological, paleontological, mineralogical, petrographic, structural, and microstructural analyses carried out on organic-rich shales exposed at the Favignana Island of Sicily, Italy. The analyses focus on Upper Triassic yellowish siltstones and greyish laminated dolomitic limestones, which form a 10's of m-thick succession exposed along the westernmost portion of the Sicilian fold-and-thrust belt. The studied succession deposited in a coastal lagoon associated t…
“The datafication and commodification of Italian schools during the Covid-19 crisis. Implications for policy and future research”
2022
Big Data and algorithms increasingly inform public policymaking and institutional practices, producing an impact on people’s everyday life. An emerging body of scholarly research—Critical Data Studies—has been working on this role shedding light on how society’s current platformisation is linked to a much longer privatization and reorganization of the public sector. This chapter intends to reflect on how the Covid-19 pandemic has dramatically accelerated these processes focusing on school education in particular. Health Big Data and apps have been crucial to take concrete measures to fight the pandemic, while platforms have helped organize vaccination rounds. Nevertheless, they have also be…
Optiskās koherences tomogrāfijas loma vēlīnās vaskulārās atbildes reakcijas novērtēšanā pēc biorezorbējošā stenta implantācijas
2019
Ievads. Pēdējos gados pieaug perkutānas koronārās intervences pielietojums, jo šobrīd tā ir viena no galvenajām metodēm koronārās sirds slimības ārstēšanā. Laika gaitā perkutānā koronārā intervence (PKI) ir pieredzējusi ievērojamu ārstniecisko attīstību. Ievērojami uzlabojumi ir stentu tehnoloģijā, kā arī tehniski uzlabojumi un farmakoterapijas progress arvien vairāk uzlabo PKI rezultātus. Bioresorbējošie koronārie stenti ir ievērojama inovācija, kam ir potenciāls uzlabot ārstēšanas rezultātus pacientiem, kam veic PKI, un to mērķis ir mazināt metāla stentu trūkumus. Pētījuma mērķis: Novērtēt vaskulārās atbildes reakciju, izmantojot optiskās koherences mērījumus, pacientiem tūlīt, pēc viena …
