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

    University essay from Umeå universitet/Avdelningen för fysioterapi

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. READ MORE

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

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

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

    Abstract : 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. READ MORE

  5. 4. DURABILITY STUDY OF REJUVENATED RAP BINDERS

    University essay from KTH/Kemiteknik

    Author : An Na Lay; [2022]
    Keywords : RAP reclaimed asphalt pavement ; rejuvenator; bitumen; rheology; ageing; RAP; bitumen; föryngringsmedel; reologi; åldring;

    Abstract : När priset på naturtillgångar ökar samt att industrier måste ställa om till en mer hållbar verksamhet innebär detta även en omställning för asfaltsindustrin. Ett sätt för att använda mer återvunnet material i asfaltsindustri är att använda bindemedlet från gammal asfaltsmassa (eng.: reclaimed asphalt pavement, RAP). READ MORE

  6. 5. An Infrared Stellar Thermometer: Exploiting IGRINS Spectra

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Emelie Sandved; [2022]
    Keywords : Effective temperature; K-giants; surface gravity; oxygen abundance; carbon abundance; CO lines; OH lines; line sensitivities; Physics and Astronomy;

    Abstract : Using the infrared (IR) spectral range when measuring stellar spectra is beneficial compared to using the optical range mainly when observing distant stars through the dust dense interstellar regions in the Galactic mid-plane. Methods to determine stellar parameters from IR spectra are, however, not fully developed yet because technological difficulties in creating reliable IR detectors have slowed the advance of such methods.
