Abstract:

The medical field has been a part of the smart textile area for quite some time. With time come technological advancement and the two fields converge on more and more areas. One such area is that of using textile electrodes, textrodes, for measuring bioelectrical activity, such as heart rate for ECG analysis. There are many components that make for a successful textile electrode and though many studies have been made in the subject there are several aspects that still are difficult. By using textile electrodes the problem with skin irritation from electrolyte gels, commonly used for convention

Abstract:

Physicians’ understanding of bio-signals, measured using medical instruments, becomes the foundation of their decisions and diagnoses of patients, as they rely strongly on what the instruments show. Thus, it is critical and very important to ensure that the instruments’ readings exactly reflect what is happening in the patient’s body so that the detected signal is the real one or at least as close to the real in-body signal as possible and carries all of the appropriate information. This is such an important issue that sometimes physicians use invasive measurements in order to obtain the real

Abstract:

Neuromuscular electrical stimulation (NMES) is a modality of electrotherapy which is aiming to restore and improve muscle function by injecting small levels of current into the muscle using different types of electrodes. Advantages are seen in using textile electrodes which can be integrated into wearables. Previous research has been done for the development of textile stimulation electrodes. However, the focus has not been on the electrode construction itself. Therefore, the influence of electrode construction parameters of knitted electrodes as well as of the electrode condition, i.e. wet or

With these methods the work function was measured, as well as the highest occupied molecular orbital (HOMO) onset. Additionally band bending effects were studied by illuminating the samples while measuring the work function with the Kelvin probe so called surface photovoltage.

Viruses and their morphology have been detected and studied with electron microscopy (EM) since the end of the 1930s.

It both serves as a routine diagnostic technique as well as an essential tool for detecting infectious agents in new and unusual disease outbreaks. The technique does not depend on virus specific targets and can therefore detect any virus present in the sample. New or reemerging viruses can be detecte

Electron beam freeform fabrication (EBF3) is a rapid metal deposition process that works efficiently with the wieldable alloy Inconel 718 (IN 718). EBF3 is a developing additive manufacturing (AM) process that can manufacture IN 718 parts directly from computer aided design (CAD) data. EBF3 can produce parts significantly faster and more energy efficient than competing IN 718 AM technologies. The EBF3 process utilizes metal wire feedstock which is induced into a molten pool using a focused electron beam in a vacuum environment. This allows parts to be built layer by layer, creating intricate s

Abstract:

Ce travail a pour but de relier carboxyréactivité et caractéristiques de 5 cokes. On étudie en fonction de la gazéification: texture poreuse, microtexture et sites actifs. La confrontation des résultats conduit à des conclusions concordantes et complémentaires. Plus un coke est microporeux, plus il est réactif. Cependant la mésoporosité ouvre l'accès aux réactifs. Une forte réactivité résulte de la présence simultanée de micro- et de mésoporosité ce qui est en accord avec le fait que les cokes les plus réactifs présentent une grande diversité dans les dimensions des domaines d'O.

Abstract:

A indústria têxtil está entre uma das principais atividades do Brasil, sendo relevante em número de empregos, quantidade e diversidade de produtos e principalmente pelo volume de água utilizado nos processos industriais e na geração de efluentes. Esses efluentes são misturas complexas que se caracterizam pela presença de corantes, surfactantes, metais, sequestrantes, sais entre outras substâncias químicas com potencial tóxico a biota aquática. Considerando a escassez de tratamentos adequados a esses efluentes, novas tecnologias são essenciais em que se destacam os processos de oxidação avançad

This thesis describes the possibilities of wearable antennas and the basic properties description. Numeric model for ISM 2,4 GHz band is created by CST Microwave Studio®. The thesis also deals with the human body proximity effect by two models of human tissue. The effect of flexibility to antenna parameters is evaluated. Several samples of the antenna has been created and measured. Obtained results has been compared with numeric model and with the literature.

Abstract:

Thermal barrier coatings (TBCs) of ZrO2-7wt% Y2O3 were deposited by electron beam physical vapor deposition (EB-PVD) onto stationary flat plates and cylindrical surfaces in a multiple ingot coater. Crystallographic texture, microstructure, and deposition rate were investigated in this thesis. The crystallographic texture of EB-PVD TBCs deposited on stationary flat surfaces has been experimentally determined by comparing pole figure analysis data with actual column growth angle data. It was found that the TBC coating deposited directly above an ingot exhibits <220> single crystal type crystal

Abstract:

Les procédés dits d'oxydation avancés (POA) permettent la dégradation totale (minéralisation) en milieu aqueux des polluants organiques persistants et/ou toxiques pour l'homme et pour l'environnement. Cette étude porte sur l'application de deux POA principaux : électro-Fenton et photo-Fenton, au traitement des eaux polluées par des colorants de textile. La particularité de ces procédés tient à la génération dans le milieu d'entités oxydantes très réactives, les radicaux hydroxyles (●OH) qui sont capables d'oxyder n'importe quelle polluant organique ou organométallique jusqu'au stade ultime d'o

Les fils composites Cu/Nb étudiés ici sont d'excellents candidats pour les bobines non destructives générant des champs magnétiques pulsés intenses (B ≥ 100T). Ils sont fabriqués par Accumulative Drawing and Bundling (ADB) et sont constitué de renforts continus de Nb dans une matrice multi-échelles de Cu. Ces travaux rentrent dans le cadre du projet METAFORES (ANR-12-BS09-0002), visant l’évaluation des effets de taille et d’architecture sur les propriétés des conducteurs Cu/Nb. L’objectif principal consiste donc à caractériser leur microstructure et leurs propriétés à chaque étape de la fabric

Previamente al ennoblecimiento textil, los tejidos de algodón son sometidos a procesos de preparación (desencolado, descrudado y blanqueo) que consiguen la eliminación de impurezas presentes en la superficie de la fibra. El presente trabajo aborda el estudio del proceso de blanqueo de tejidos de algodón crudo y descrudado, por medio de técnicas electroquímicas. Para ello se han empleado metodologías basadas en la electro-oxidación indirecta, concretamente la electro-generación de cloro activo (o electrocloración) o de H2O2 (a veces denominados electro-peroxidación) en ausencia o presencia de c

L'analyse des relations entre la composition, la structure et la texture des fromages à pate molle constitue la base de cette étude. La méthodologie utilisée a pour but de classer scientifiquement, au moyen de critères objectifs, les fromages à pate molle parmi les autres catégories de fromages. Une première partie de l'étude est consacrée à la caractérisation des propriétés texturales des fromages en relation avec leur composition physicochimique. Dans ce but, des méthodes rhéologiques et d'évaluation sensorielle ont été mises en œuvre. Le traitement statistique des résultats permet de situer
