Acetone Vapor-Sensing Properties of Chitosan-Polyethylene Glycol Using Surface Plasmon Resonance Technique

2020

To non-invasively monitor and screen for diabetes in patients, there is need to detect low concentration of acetone vapor in the range from 1.8 ppm to 5 ppm, which is the concentration range of acetone vapor in diabetic patients. This work presents an investigation for the utilization of chitosan-polyethylene glycol (PEG)-based surface plasmon resonance (SPR) sensor in the detection of trace concentration acetone vapor in the range of breath acetone in diabetic subjects. The structure, morphology, and elemental composition of the chitosan-PEG sensing layer were characterized using FTIR, UV-VIS, FESEM, EDX, AFM, and XPS methods. Response testing was conducted using low concentration of aceto…

Szkoła - w stronę wielozmysłowego i wielointeligentnego poznawania świata

2019

Artykuł dotyczy teorii inteligencji wielorakich a także kompetencji zawodowych współczesnego nauczyciela jest interdyscyplinarnym ujęciem zagadnienia z pogranicza - : psychologii, neurobiologii – a umiejscowionych kontekstach współczesnej pedagogiki. Teoria o istnieniu wielu niezależnych od siebie inteligencji Howarda Gardnera kwestionująca traktowanie inteligencji jako „jednolitej konstrukcji” jest bazą wyjściową do deliberacji nad osobniczymi predylekcjami sensorycznymi ucznia. Zdobyta wiedza takiej proweniencji pozwala nauczycielowi na bardziej kreatywną interakcje edukacją i wychowawczą z uczniem

Joint Optimization of Sensor Selection and Routing for Distributed Estimation in Wireless Sensor Networks

2014

Avances recientes en redes inalámbricos de sensores (WSNs, Wireless Sensor Networks) han posibilitado que pequeños sensores, baratos y con recursos limitados tanto en sensado, comunicación, como en computación, sean desplegados a gran escala. En consecuencia, las WSNs pueden ofrecer diversos servicios en importantes aplicaciones para la sociedad. Entre las varias restricciones que aparecen en el diseño de WSNs, tales como la limitación en energía disponible, procesamiento y memoria, la limitación en energía es muy importante ya que en muchas aplicaciones (ej., monitorización remota de diferentes entornos, edificios administrativos, monitoreo del hábitat, los incendios forestales, la atenció…

Off-line methods for determining air quality in museums

2010

This paper will examine three methodologies deployed in off-line research relating to air quality in museums. These methodologies made use of sensors based on the different chemical-physicalproperties of various materials (corrosiveness, hardness and absorption). Various field applications were applied to case studies, which were performed in two museums in Palermo, Italy: the Regional Gallery of Palazzo Abatellis and the Diocesan Museum. This review of methodologies and sensors examines which protocol should be put into practice in museums in monitoring the air quality of display spaces and the conservation of cultural artefacts.

A Self-powered Ambient Light Power Measurement Platform with Time-domain Readout

2021

Internet of Things (IoT) provides more and more adequate infrastructures for many applications and advanced services. This scenario promotes the ability to satisfy the growing demand for innovative measuring systems, increasingly popular consisting of intelligent nodes, totally wireless, easy to install, and that requires the least possible maintenance. In this context, this paper aims to contribute to state of the art with an energy-autonomous and battery-free measurement platform designed to measure the ambient light power when its level exceeds the sensitivity threshold. The measurement platform utilizes a single transducer to scavenge energy and concurrently measure the ambient light in…

Redonner l’envie de manger aux personnes âgées en institution : impact de quatre facteurs environnementaux sur la prise alimentaire et le plaisir lié…

2012

Comme l’ont montré plusieurs travaux, l’entrée en Etablissement d’Hébergement pour Personnes Agées Dépendantes (EHPAD) s’accompagne d’une augmentation du risque de dénutrition (HAS, 2007 ; Sulmont-Rossé et al., 2012). Parmi les facteurs susceptibles d’affecter la prise alimentaire, il a été montré que l’environnement qui entoure le repas (de l’assiette à l’ambiance générale) contribuait fortement à l’appétit et à la prise alimentaire des résidents d’EHPAD (Nieuwenhuizen et al. 2009 ; Nijs et al. 2009). De fait, quatre études ont montré qu’une amélioration globale de l’environnement (changement de mobilier, décoration de la salle à manger, réorganisation du personnel…) pouvait entrainer une …

MEHANOLUMINISCENTO MATERIĀLU PIELIETOJAMĪBA OPTOELEKTRISKO SENSORU IZVEIDEI UN METODES IZSTRĀDE TO ĪPAŠĪBU IZPĒTEI

2021

Mehanoluminiscence (ML) ir spontāna gaismas emisija mehāniskas mijiedarbības rezultātā. Kaut gan efekts tika atklāts simtiem gadu atpakaļ, tas neatrada plašu, praktisku pielietojumu. Tomēr pētījumi norāda uz to, ka ML varētu tikt pielietota mehāniskā sprieguma sensoru izveidei. Viens no limitējošajiem faktoriem ML plašai pielietošanai ir šaurais izpētīto materiālu klāsts, kuriem piemīt intensīva un pašatjaunojama luminiscence. Pēdējos gados strauji pieaug ar lantanīdiem leģētu materiālu pētījumu skaits, kuri gan paaugstina materiālu luminiscences intensitāti, gan paplašina ar ML iegūstamo emisijas viļņa garumu diapazonu. Darba mērķis ir izveidot mērījumu sistēmu un veikt mehanoluminiscenta …

Vairākslāņu grafēna un nitrocelulozes kompozīta elektroda iegūšana un izpēte slāpekļa savienojumu noteikšanā

2018

Slāpekļa savienojumi, jo īpaši NOx, tiek uzskatīti par vieniem no cilvēka veselībai bīstamākajiem savienojumiem gaisa piesārņojumā. Palielinoties fosilā kurināmā dedzināšanas apjomam gan iekšdedzes dzinējos, gan kurtuvēs, paaugstinās arī tā degšanas blakusproduktu daudzums it īpaši pilsētās ar lieliem transporta sastrēgumiem, kas negatīvi ietekmē pilsētnieku veselību, nerunājot par dzīvniekiem un augiem. Lai spētu precīzāk ierobežot kaitīgo savienojumu daudzuma izvadīšanu atmosfērā, rodas nepieciešamība pēc jutīgiem šo savienojumu gāzu sensoriem. Potenciāls materiāls gāzu noteikšanā ir grafēns kā divdimensionāls materiāls, piemērotākais gāzu sensoru pielietojumos lielā virsmas laukuma dēļ. …

Ultrasound assisted method to increase soluble chemical oxygen demand (SCOD) of sewage sludge for digestion

2004

The aim of this study was to clarify the possibilities to increase the amount of soluble chemical oxygen demand (SCOD) and methane production of sludge using ultrasound technologies with and without oxidising agents. The study was done using multivariate data analyses. The most important factors affected were discovered. Ultrasonically assisted disintegration increased clearly the amount of SCOD of sludge. Also more methane was produced from treated sludge in anaerobic batch assays compared to the sludge with no ultrasonic treatment. Multivariate data analysis showed that ultrasonic power, dry solid content of sludge (DS), sludge temperature and ultrasonic treatment time have the most signi…
