  1. 16. Analyzing microplastics in soils : Evaluating canola oil extractions

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anna Bottone; [2019]
    Keywords : Microplastics; extraction recovery; OEP method; organic-rich soils;

    Abstract : Small fragments of artificial polymers (microplastics, MPs) has been reported for multiple environmental matrices from our planet. The omnipresent existence of these microplastics even in remote polar areas have raised concern about their potential environmental impacts and created a need for effective and standardized analytical methods targeting their detection in environmental samples.

  3. 17. Real-Time Monitoring of Neurovascular Cells

    University essay from KTH/Mikro- och nanosystemteknik

    Author : Vladimir Banovic; [2018]
    Keywords : ;

    Abstract : Organs-on-a-chip devices are perfused cell culture systems aimed at creating the minimal functional unit of an organ - suchas the neurovascular unit (NVU) of the brain. NVU-on-a-chip platforms can provide an effective framework for studyingcentral nervous system physiology, disease etiology and provide a mean for drug development. READ MORE

  4. 18. Specialization of an Existing Image Recognition Service Using a Neural Network

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

    Author : Sara Ersson; Oskar Dahl; [2018]
    Keywords : Neural networks; Machine learning; Tensorflow; Google Cloud Vision; Image recognition; Neurala nätverk; Maskininlärning; Tensorflow; Google Cloud Vision; Bildigenkänning;

    Abstract : To help combat the environmental impacts caused by humans this project is about investigating one way to simplify the waste management process. The idea is to use image recognition to identify what material the recyclable object is made of. A large data set containing labeled images of trash, called Trashnet, was analyzed using Google Cloud Vision. READ MORE

  5. 19. Development of a Detector System for Detection of Thermal Neutrons from Spent Nuclear Fuel

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Daniel Söderström; [2016]
    Keywords : neutron detection; neutron; 10B; boron-10; nuclear physics; boron; neutron detector; scintillator; boron carbide; B4C; nuclear fuel; repository; SKB; Physics and Astronomy; Technology and Engineering;

    Abstract : The nuclear reaction 10B(n,alpha)7Li* was utilised to develop a neutron detection system. This system has the purpose of being used to detect the thermal neutron radiation emitted by spent nuclear fuel, before it is transported to a final repository. READ MORE

  6. 20. Development of optimized Raman Spectroscopy setup for species detection in flames

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Henrik Johansson; [2016]
    Keywords : multi-pass; Raman; spectroscopy; species concentration; flames; combustion; Stokes; high-power laser; Physics and Astronomy;

    Abstract : A multi-pass Raman spectroscopy setup, consisting of a measuring cell built as a cavity, using two concave circular mirrors, has been constructed and optimized. As the light reflects between the mirrors, the Stokes Raman signal is enhanced with every pass through the cavity. READ MORE
