Multicomponent bionanocomposites based on clay nanoarchitectures for electrochemical devices

2019

[EN] Based on the unique ability of defibrillated sepiolite (SEP) to form stable and homogeneous colloidal dispersions of diverse types of nanoparticles in aqueous media under ultrasonication, multicomponent conductive nanoarchitectured materials integrating halloysite nanotubes (HNTs), graphene nanoplatelets (GNPs) and chitosan (CHI) have been developed. The resulting nanohybrid suspensions could be easily formed into films or foams, where each individual component plays a critical role in the biocomposite: HNTs act as nanocontainers for bioactive species, GNPs provide electrical conductivity (enhanced by doping with MWCNTs) and, the CHI polymer matrix introduces mechanical and membrane pr…

Biosensor Analysis of β2-Glycoprotein I–Reactive Autoantibodies: Evidence for Isotype-Specific Binding and Differentiation of Pathogenic from Infecti…

2007

Abstract Background: For the laboratory diagnosis of the antiphospholipid syndrome (APS) we developed a biosensor with the ability to distinguish between disease-relevant anti-β2-glycoprotein I (β2GPI) autoantibodies (anti-β2GPI) and pathogen-specific β2GPI cross-reactive antibodies that occur transiently during infections. Methods: We used a surface plasmon resonance (SPR) biosensor device. For the detection of anti-β2GPI in serum samples, affinity-purified human β2GPI was covalently attached to a functionalized n-alkanethiol self-assembling monolayer on the biosensor chip. After verifying the specificity of the biosensor system with a panel of monoclonal antibodies to β2GPI, we analyzed s…

A novel device for intracolonoscopy cleansing of inadequately prepared colonoscopy patients: a feasibility study.

2019

Abstract Background The importance of high quality preprocedural bowel preparation is widely acknowledged, but suboptimal bowel cleansing still occurs in up to 20 % of all colonoscopy patients. The aim of this study was to evaluate the performance of a novel intraprocedural cleaning device for cleaning poorly prepared colons. Methods This multicenter feasibility study included patients aged 18 – 75 years who were referred for colonoscopy. Intraprocedural cleaning was performed in patients after a limited preprocedural bowel preparation regimen (2 days of dietary restrictions and 2 × 10 mg bisacodyl). The primary outcome was the proportion of adequately prepared patients (Boston Bowel Prepar…

Plant visibility through mobile learning? Implementation and evaluation of an interactiveFlower Huntin a botanic garden

Plants have an enormous importance for life on earth but are often overlooked. This phenomenon called plant blindness is reinforced as students prefer to spend their recreation time with modern med...

Three Step Bluetooth Positioning

2005

This paper discusses a three step procedure to perform high definition positioning by the use of low cost Bluetooth devices. The three steps are: Sampling, Deployment, and Real Time Positioning. A genetic algorithm is discussed for deployment optimization and a neural network for real time positioning. A case study, along with experiments and results, are finally discussed dealing with a castle in Sicily where many trials were carried out to the end of arranging a positioning system for context aware service provision to visitors.

A Biologically Inspired Representation of the Intelligence of a University Campus

2016

Abstract Intelligence or smartness in an urban environment implies several factors directed to improve quality of life and efficiency. It is important to note that in this context the inclusion of citizens and their devices is a key factor for reaching smartness. Data from mobile devices are increasingly used in everyday activities and have to be considered a useful means for handling and analyzing knowledge and communications. This paper shows how to represent important data when dealing with smartness by creating an analogy between the representation of human brain areas, activated when specific tasks are performed, and groups of students when behaviors or needs arise. The brain traffic c…

Mobiiliopetuksen käyttömahdollisuuksia : oppilaiden omien mobiililaitteiden käyttö peruskoulun alakoulun opetuksessa

2015

Muutaman viime vuoden aikana mobiililaitteiden käyttö kouluissa on yleistynyt. Tämä on osittain aiheuttanut ristiriitaista keskustelua laitteiden käytöstä opetuksessa. Osa opettajista on ottanut mobiililaitteet opetuskäyttöön innokkaasti. Mobiiliopetuksen mahdollisuuksia ei kuitenkaan ole vielä kovin paljon tutkittu. Tällä tutkimuksella oli tarkoitus selvittää, mitä mahdollisuuksia oppilaiden omat mobiililaitteet tarjoavat opetukseen. Aineiston analyysissa pyrittiin etsimään tietoa siitä, miten ongelma-perustaisen opetuksen menetelmä ja pelillisyys vaikuttavat opetus- ja oppimisprosessissa, kun opiskelumenetelmänä käytetään mobiilioppimista ja oppilaiden omia mobiililaitteita. Tutkimus teht…

Mnemoniskie paņēmieni drukātajos sludinājumos

2021

Mūsdienās reklāmas tiek lietotas, lai ietekmētu patērētāju lēmumu pieņemšanu, un tajās tiek lietotas dažādas reklāmas metodes. Līdztekus citām metodēm, reklāmās tiek lietoti arī mnemoniskie paņēmieni, kas palīdz labāk atcerēties reklāmas tekstus. Šī darba mērķis ir izpētīt mnemoniskos paņēmienus un analizēt mnemonisko paņēmienu biežumu Lielbritānijas laikrakstos, izmantojot kvalitatīvās un kvantitatīvās pētījumu metodes - diskursa un biežuma analīzi. Kopumā tika analizēti četrpadsmit laikraksti, lai tajos atrastu mnemonisks ierīces. Šī pētījuma rezultāti apstiprina, ka 61 no 247 laikrakstu reklāmām ir mnemoniskie paņēmieni, visos 14 Lielbritānijas laikrakstos katrā laikraksta numurā ir vism…

Personalized multimedia touristic services for hybrid broadcast/broadband mobile receivers

2010

This paper presents the topology of a multimedia tourism service that targets mobile devices equipped with broadband and either multicast or broadcast access capabilities. Multicast / Broadcast access is used to handle the delivery of multimedia data to many simultaneous users in the service area. The solution adopted is based on existing standards for mobile TV services, but introducing features that enable the provision of generic multimedia services on top of mobile hybrid broadband and broadcast networks. Furthermore, this paper shows how to use standardized interfaces originally defined for interactive mobile TV broadcasting to build personalized mobile multimedia services that do not …
