Swarming of micron-sized hematite cubes in a rotating magnetic field -- Experiments
2020
Energy input by under-field rotation of particles drives the systems to emergent non-equilibrium states. Here we investigate the suspension of rotating magnetic cubes. Micron-sized hematite cubes are synthesized and observed microscopically. When exposed to a rotating magnetic field, they form rotating swarms that interact with each other like liquid droplets. We describe the swarming behaviour and its limits and characterize swarm size and angular velocity dependence on magnetic field strength and frequency. A quantitative agreement with a theoretical model is found for the angular velocity of swarms as a function of field frequency. It is interesting to note that hematite particles with p…

Sensitivity of water quality of three contrasted north-eastern French watersheds to climate change (2006-2100) using SWAT model
2015
International audience; The SWAT model has been chosen to assess climate change impacts on water quality of three subbassins ofnorth-eastern France: located on headwaters of three major rivers of France (Loire, Seine and Rhône riversrespectively). These watersheds have a size less than 3000km² and present different hydrogeological andgeological characteristics. Land-use as well as their agricultural practices being also diversified, the threewatersheds studied constitute a relevant experimentation area. The goal of this study is to assess local vulnerability of surface water quality (sediments, nutrients,dissolved oxygen loads) to climate change (2006-2100) following the Representative Conc…

Target 5G visible light positioning signal subcarrier extraction method using particle swarm optimization algorithm
2021
International audience; With the explosive growth of demand for Internet of Things (IoT) applications and the increasing dependence of users on wireless connections, indoor location based service(LBS) under 5G-Public-Private Partnership (5G-PPP) using cases have received more attention and get rapid development. Thanks to the safty, security and customization of 5G network pointed by 5G forum white paper, indoor positioning systems using unified 5G New Radio (NR) signals have become the focus of the next generation of visible light positioning (VLP) systems. In 5G New Radio(NR) frame, totally 192 subcarriers are used to carry positioning reference signal(PRS). In order to improve the positi…

Auto reklāmas plakātu vēstījumu analīze
2020
Mūsdienās reklāma ieņem nozīmīgu vietu mūsu dzīvēs un katru dienu to skaits pasaulē tikai pieaug. Cilvēki ir cieši saistīti ar reklāmu gan uz ielas, gan televizora ekrānā, internetā un žurnālos. ‘Volkswagen’ ir starptautisks automašīnu ražotājs, kurš savos reklāmu vēstījumos attēlo jaunākos auto modeļus, to tehniskās īpašības un dizainu. Auto reklāmas plakātu vēstījumi tiek izteikti caur attēliem, dažādiem vizuāliem līdzekļiem un valodas lietojumu. Bakalaura darba mērķis ir izpētīt un izskaidrot auto reklāmas plakātu vēstījumus un raksturot tajos valodas un vizuālo līdzekļu lietojumu. Kā arī, izpētīt vai auto reklāmas plakātu vēstījumu analīze ir veidota, lai pārliecinātu pircējus un veidot…
Paediatric solid oral dosage forms for combination products: Improving in vitro swallowability of minitablets using binary mixtures with pellets
2023
There is a growing interest in determining and improving the acceptability of solid oral dosage forms (SODF) in paediatric populations. Combination products can be an interesting solution to combine two active pharmaceutical ingredients. This study shows that binary mixture of paediatric SODF could enhance formulation swallowability and palatability. Using the Paediatric Soft Robotic Tongue (PSRT) – an in vitro device inspired by the anatomy and physiology of 2-year-old children – we investigated the oral phase of swallowing of multi-particulate formulations, i.e., pellets (350 and 700 µm particles), minitablets (MTs, 1.8 mm), and their binary mixtures (BM), by measuring the oral swallowing…
Inhibition of bacterial virulence factors of foodborne pathogens by paprika (Capsicum annuum L.) extracts
2022
Abstract Capsicum annuum extracts of different polarities were tested for their antimicrobial, antibiofilm, and anti-Quorum sensing (QS) activity against several pathogenic microorganisms and possible toxic effects using an in vivo model (Galleria mellonella L.). Hexane (HE) and Chloroform extract (CE) were the most active in inhibiting biofilm formation of the eight bacteria tested, with inhibition percentages between 22 and 88% for a concentration of 100 μg/mL. These extracts were potent inhibitors of Staphylococcus aureus biofilm, and microscopy analysis confirmed a significant reduction in adhered cells. Moreover, polystyrene surfaces coated with these extracts decreased Staph. aureus a…
