  1. 1. Comparison of muscle oxygen kinetics between occluded and non-occluded dynamic low-intensity exercise performed till failure : A quantitative study

    Kandidat-uppsats, Umeå universitet/Avdelningen för fysioterapi

    Författare :Natalie Smith; Josefine Johansson; [2023]
    Nyckelord :venous occlusion; muscle oxygenation kinetics; blood flow restricted exercise; ischemia; exercise failure; low-intensity strength training; Near-infrared spectroscopy;

    Sammanfattning : Aim: To examine local muscle oxygen kinetics when performing wrist extensions till failure in an occluded versus non-occluded state, to compare the perceived ratings of pain and local muscle exertion, and analysing presence of gender differences. Methods: Twenty-one healthy individuals (mean age 25,6±3. LÄS MER

  3. 2. Deriving Spectral Maps from JWST Data : A Study of Enceladus’ Plumes

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Stephan Weissenböck; [2023]
    Nyckelord :Data Analysis; Enceladus; Plumes; Atmosphere; JWST; NIRSpec; IFU; Infrared spectroscopy; Dataanalys; Enceladus; plym; atmosfär; JWST; NIRSpec; IFU; infraröd spektroskopi;

    Sammanfattning : This study investigates the presence of water vapor plumes in the region south of Enceladus, a moon in the Saturnian system, through observations conducted by the James Webb Space Telescope. Enceladus is believed to harbor a subsurface ocean or localized water reservoir that gives rise to water geysers, expelling vapor into its tenuous atmosphere and outer space. LÄS MER

  4. 3. Prediction of Plastic Fragments in Recycled Paper Using Near-Infrared Spectroscopy

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Fidan Alieva; [2023]
    Nyckelord :Near-infrared spectroscopy; paper packaging; barrier materials; recycling; multivariate data analysis; Nära-infraröd spektroskopi; pappersförpackningar; barriärmaterial; återvinning; multivariat dataanalys;

    Sammanfattning : Sustainability has gained a lot of attention in the field of research. Researchers and consumers both prioritize sustainability and environmental issues over previously dominant materials, such as plastic. Packaging and disposable items that used to be made of plastic have largely been replaced with paper. LÄS MER

  5. 4. Miljövänlig och hållbar additiv tillverkning

    Kandidat-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Yasmina Khadige; Ida Lönn; Sara Thunholm; [2022]
    Nyckelord :Filament; Polyamide 12; SLS waste; FFF printing; recycling;

    Sammanfattning : Den additiva tillverkningsindustrin associeras ofta med en hållbar hushållning av resurser. Trots detta har denna industriavfall med stor potential till vidare användning. LÄS MER

  7. 5. Prototype Instrumentation for Frequency Domain – Functional Near Infrared Spectroscopy

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Rohit Rathnam Nareshkumar; [2022]
    Nyckelord :Neurofeedback; Frequency domain fNIRS; vertical-cavity surface-emitting laser; silicon photomultiplier;

    Sammanfattning : Frequency domain functional near infrared spectroscopy (FD-fNIRS) is a tissue optical measurement technique used to measure absolute haemoglobin concentrations in brain tissue. This work is intended to be the first step in the development of a wearable, low-cost FD-fNIRS device for neurofeedback applications. LÄS MER
