  3. 2. Anisotropic Muscle Phantoms for Shear Wave Elastography Assessment of the Levator Ani Muscle Properties

    Kandidat-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Bleona Koxha; Melissa Jova Martinez; [2023]
    Nyckelord :pelvic floor disorder; levator ani muscle; shear wave elastography; phantom; anisotropy; polyvinyl alcohol; bäckenbottenbesvär; levator ani muskel; shear wave elastografi; fantom; anisotropi; polyvinylalkohol;

    Sammanfattning : Pelvic floor disorder is an emerging research area and is highlighted in many pelvic floor studies. Assessment methods for this type of injury are lacking and new methods for prevention and diagnosis are needed. Pelvic floor disorders are common among women and can lead to suffering for the patient. LÄS MER

  4. 3. Filtration of oil-in-water nanoemulsions for potential adjuvant development applications

    Master-uppsats, KTH/Kemiteknik

    Författare :Emilie Degeneve; [2023]
    Nyckelord :Filtration of oil-in-water nanoemulsions for potential adjuvant development applications; Vaccin; adjuvans; nanoemulsion; ytaktiva ämnen; filtrering;

    Sammanfattning : I den här studien undersöktes innovativa sammansättningar för produktion av vaccinadjuvans. Syftet var att stabilisera nanoemulsioner av olja i vatten, med hjälp av squalenolja (som används inom läkemedelsindustrin), med olika ytaktiva ämnen och att testa filtrerbarheten hos dessa nanoemulsioner.

  5. 4. 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

  7. 5. 3D printer in dosimetry and mammography – designing and testing an OSL dosemeter holder and a low contrast-detail phantom

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Måns Boll; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: Today, 3D printing is a versatile tool used in a wide range of fields. With the advent of more cost-effective fused deposition modelling (FDM) 3D printing technologies it is time to investi- gate what such a 3D printer has to offer in radiation science applications.
