Optisks čukstošās galerijas modu mikrorezonatora mitruma sensors

2020

Šajā bakalaura darbā tiek pētīti čukstošās galerijas modu (ČGM) mikrorezonatori un to pielietojums gaisa mitruma kontrolei un mērīšanai. ČGM rodas, kad gludas virsmas optiskajos dobumos notiek konstruktīva interference. Rezultātā rezonatorā paliek tikai noteikti viļņu garumi, kas atkarīgi no rezonatora izmēra un laušanas koeficienta. Līdz ar to, ja kāds no šiem parametriem gaisa mitruma izmaiņu dēļ mainās, rezonatoru var izmantot kā mitruma sensoru. Eksperimentam izvēlēts glicerīna piliens, kurā ČGM rezonanses ierosinātas ar skenējamu pusvadītāju lāzeru. Izveidota eksperimentāla iekārta, ar kuru var pētīt šāda veida mitruma sensoru. Rezultātā iegūta jutība vidēji 4,14 nm/% RH lāzera viļņa g…

Caracterización espacio frecuencial y funcional de los fenómenos de prevalencia ocular

2018

Determinar con exactitud la dominancia ocular es importante en aquellos casos en los que es necesario inducir monovisión. Esto sucede en determinadas técnicas de cirugía refractiva, intervenciones de cataratas y adaptaciones de lentes de contacto. Especialmente críticas son las intervenciones quirúrgicas donde el proceso es irreversible y las inadaptaciones a la situación creada, si la dominancia ocular ha sido incorrectamente determinada, pueden crear importantes problemas de astenopia visual de difícil solución debido a la reducida plasticidad del sistema visual de los sujetos, por lo general adultos. Poder disponer de un sistema que pueda proporcionar de forma sencilla y fiable toda la i…

Photoluminescent Detection of Human T-Lymphoblastic Cells by ZnO Nanorods.

2020

The precise detection of cancer cells currently remains a global challenge. One-dimensional (1D) semiconductor nanostructures (e.g., ZnO nanorods) have attracted attention due to their potential use in cancer biosensors. In the current study, it was demonstrated that the possibility of a photoluminescent detection of human leukemic T-cells by using a zinc oxide nanorods (ZnO NRs) platform. Monoclonal antibodies (MABs) anti-CD5 against a cluster of differentiation (CD) proteins on the pathologic cell surface have been used as a bioselective layer on the ZnO surface. The optimal concentration of the protein anti-CD5 to form an effective bioselective layer on the ZnO NRs surface was selected. …

A novel device for assessing the health risk caused by hand-arm vibrations in olives harvesting

2012

The mechanization of olive harvesting is very important both to reduce the costs of production and to assure the oil quality because the manual harvest does not allow to operate at the right time and also need a long period to be completed. The use of portable shakers, that are spreading more than others typologies, can give a solution to the problem. However, the use of such equipment may involve risk of exposure to hand-transmitted vibration. The aim of this study was to assess the level of exposure to hand-arm vibration of the operators using portable shakers (reference standards UNI EN ISO 5349-1:2004, Italian Low Decree 81/2008). The research presented here concerns the definition of a…

The effectiveness of personalized design to feed elderly people

2015

Beyond the physiological age, the elderly population is characterized by a high heterogeneity in terms of physical, psychological and sociological status (Maître et al, 2015). Regarding eating behavior, several studies have highlighted a large inter-individual variability in chemosensory abilities (i.e. the ability to perceive an odor or a taste; Sulmont-Rossé et al, 2015) and oral-heath status (i.e. dental status, salivary flow; ALIMASSENS project), as well as inter-individual variability in food preference and food intake (AUPALESENS project). However, the food offer dedicated to the elderly population, and in particular to elderly people who needs help to obtain and/or prepare food for t…

Desarrollo de Aptazovid: aptasensor piezoeléctrico para la detección de SARS-CoV-2

2021

SARS-CoV-2 ha dado lugar a una pandemia en la que la detección y aislamiento de personas infectadas es clave para luchar contra el virus. La detección puede ser directa o indirecta con diferentes dianas y muestras de partida, aplicando técnicas tan conocidas como la RT-PCR o desarrollando nuevos métodos que integran herramientas como CRISPR, aunque con ciertas limitaciones. Desde hace algún tiempo, los biosensores están en auge y la pandemia ha favorecido la inversión en el desarrollo de tecnologías que superen los inconvenientes de metodologías más tradicionales. En este contexto, como solución surge Aptazovid, un aptasensor piezoeléctrico que detecta directamente la glicoproteína de super…
