   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. 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

4. 3. Prototype Instrumentation for Frequency Domain – Functional Near Infrared Spectroscopy

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

   Abstract : 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. READ MORE

6. 5. Determination of the Degree of Oxidation in Dialdehyde Cellulose Using Near Infrared Spectroscopy

   University essay from Karlstads universitet/Avdelningen för kemiteknik

   Author : Carl-Magnus Brandén; [2017]
   Keywords : dialdehyde cellulose; DAC; NIR; periodate oxidation; multivariate analysis; degree of oxidation; dialdehydcellulosa; DAC;

   Abstract : The purpose of this thesis work was to investigate possible in-, on- or at-line methods to determine the degree of oxidation in dialdehyde cellulose. Several technologies were reviewed which led to a feasibility study into a possible on-line or at-line method using near infrared spectroscopy for determining the degree of oxidation in wet dialdehyde cellulose.
