ELECTROCHEMICAL H2O2 SENSORS BASED ON Pd and Cu NANOSTRUCUTERS
2018
In the last decades, with the fast improvement of electronics, the field of sensors is highly expanding. The basic idea of sensors is to detect something and then trigger a corresponding action. This simple, but very important, concept can be used in different fields: from chemical industries to farms, from the environmental monitoring [1] to a point of care analysis [2]. Currently, talking about sensing of chemical species, different techniques are used, such as Atomic Absorption Spectroscopy (AAS), Graphite Furnace Atomic Absorption Spectroscopy (GFAAS), Inductively Coupled Plasma Mass Spectroscopy (ICP-MS), IR spectroscopy, redox titration and so on. Despite they are highly efficient in …
Sensory testing in new product development: working with children
2015
Abstract This chapter aims at briefly reviewing applications of sensory descriptive testing methods with children, as well as their limits in relation to the cognitive development of children. Children’s sensory perceptions and preferences may differ from those of adults, which may make working directly with children a must for successful product development, at least at some stages of product development. However, most reported studies with children have characterized their preferences. Some studies have used discrimination tests and ranking tasks to gain knowledge about differences among products, or about sensory abilities development. A much smaller number of studies have involved child…

Navigācijas ierīces neredzīgiem cilvēkiem: vajadzību apzināšana un eksperimentāla prototipēšana
2021
Neredzīgu cilvēku skaits palielinās proporcionāli cilvēku skaitam, līdz ar to, palielinās arī cilvēku skaits, kuriem ikdienas gaitās nepieciešama vai nu asistenta palīdzība vai palīglīdzekļi. Šajā darbā apzinātas, pētītas un analizētas neredzīgu cilvēku vajadzības saistībā ar navigācijas palīglīdzekļiem, to esamību, pieejamību un neredzīgu cilvēku prasības no jauniem palīglīdzekļiem, lai tos reāli lietotu. Darbā eksperimentēts ar divu veidu sensoriem, kas spēj noteikt attālumu līdz objektiem – ultraskaņas sensoru un infrasarkano sensoru. Eksperimenta mērķis – pārbaudīt abu sensoru darbspēju un trūkumus, salīdzināt to darbību trīs dažādās vidēs un pret trīs dažādiem šķēršļiem. Eksperimentējo…
TimeSens - un logiciel Web pour l'acquisition et le traitement des données sensorielles
2010
TimeSens est un nouveau logiciel dédié à l'acquisition et au traitement des données d'analyse sensorielle. TimeSens bénéficie de l'expérience et de l'expertise de ChemoSens, la plate-forme d'analyse sensorielle du CSGA. TimeSenspropose la plupart des protocoles standards de l'analyse sensorielle (profil, tests hédoniques, DTS), ainsi que des protocoles originaux (MATI, PSP). Les résultats collectés peuvent être analysés à l'aide de méthodes statistiques traditionnelles ou innovantes.
Voltammetric Detection of Lead(II) Using Amide-Cyclam- Functionalized Silica-Modified Carbon Paste Electrodes
2009
2-(4,8,11-Triscarbamoylmethyl-1,4,8,11-tetraazacyclotetradec-1-yl)acetamide (TETAM) derivatives bearing 1, 2, or 4 silylated arms have been synthesized and grafted to the surface of silica gel and ordered mesoporous silica samples. The resulting organic-inorganic hybrids have been incorporated into carbon paste electrodes and applied to the preconcentration electroanalysis of Pb(II). The attractive recognition properties of these cyclam derivatives functionalized with amide pendent groups toward Pb(II) species and the highly porous structure of the adsorbents can be exploited for the selective and sensitive detection of the target analyte. Various parameters affecting the preconcentration a…
Human Topoisomerase I interaction with DNA on flexible nylon substrate for malaria diagnosis
The study of interaction between human Topoisomerase I (hTopo I) and the appropriate sequences of DNA is shown, with the aim to realize a biosensor for malaria diagnosis. Topoisomerases alter the topological state of DNA by catalysing the breaking and rejoining of DNA strands1. The ligase activity is fundamental for our biosensing strategy, revealing the pathology. hTopo I was chosen as a model system for the Plasmodium analogous. The biosensor is a new flexible and easy to degrade biochip printed on nylon by dip-pen lithography (DPL). It is realized exploiting the high specificity of complementary ssDNA2 and hTopo I ligase activity. DPL operation needs ultra-low amounts of DNA (0.5 µL) to …
The promotion of tourism in Italian regions from a sensorial perspective: a website content analysis
2022
Recent tourism literature has identified the sensory dimension as key to understanding, planning and marketing tourist experiences. This paper aims to understand to what extent Italian regions consider the sensorial perspective in tourist communication, focusing the analysis on their institutional websites. We used the content analysis method considering two different periods to investigate the evolution of Italian tourism promotion. The results show that for all institutional websites, over time, attention engages only some of the five sensorial dimensions. That is, the communication does not appear balanced. Furthermore, the promotional communication in several regions is more oriented to…
Smart Wireless Sensor Networks and Biometric Authentication for Real Time Traffic Light Junctions Management
2013
The main challenge of intelligent transportation systems (ITS) is to deal with ‘real-time’ information to improve vehicular traffic management. Road data can be processed and used for dynamic traffic light management in order to reduce waiting times in queues. This paper proposes an innovative distributed architecture based on a wireless sensor network (WSN) with a network coordinator providing remote and ubiquitous authentication module for managing unexpected events. The architecture is completed by a dynamic module for street priority management depending on traffic rate. Many experimental trials have been carried out considering three different levels of traffic intensity to prove the e…
