This systematic review examines the impact of hormonal fluctuations, such as those occurring during the menstrual cycle, puberty, adulthood, and menopause, on ADHD symptoms in women. READ MORE

  3. 2. A geometric approach to calculating the limit set of eigenvalues for banded Toeplitz matrices

    University essay from Lunds universitet/Matematik LTH

    Author : Teodor Bucht; [2023]
    Keywords : Toeplitz matrices; Banded Toeplitz matrices; Limit set; Eigenvalues; Mathematics and Statistics;

    Abstract : This thesis is about the limiting eigenvalue distribution of n × n Toeplitz matrices as n → ∞. The two classical questions we want to answer are: what is the limit set of the eigenvalues, and what is the limiting distribution of the eigenvalues. Our main result is a new approach to calculate the limit set Λ(b) for a Laurent polynomial b, i.e. READ MORE

  4. 3. Design and implementation of an energy harvesting system in a prosthetic limb

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

    Author : Ódinn K. Rúnarsson; [2023]
    Keywords : Energy harvesting; Prosthetic limbs; Supercapacitors; Printed circuit boards; 3D printing; Energiinsamling; Lemmproteser; Superkondensatorer; Tryckta kretskort; 3D Utskrivning; Orkuöflun; Gervilimir; Ofurþéttar; Prentaðar rafrásir; Þrívíddarprentun;

    Abstract : Energy Harvesting, also known as power harvesting or ambient power, is the process of obtaining small amounts of power from secondary sources, such as vibrations, light, temperature variations and even radio-frequency emissions. These systems have been uncommon in personal and wearable electronics in the past, however they are slowly gaining traction. READ MORE

  5. 4. Soil Carbon Stocks in Old Growth Forest : Drivers of variability in soil organic carbon stocks in old growth boreal forests

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

    Author : Elis Ingvarsson; [2023]
    Keywords : old growth forest; boreal; soil organic carbon stocks; climate gradient;

    Abstract : Soil organic carbon (SOC) is the largest carbon pool in terrestrial ecosystems, which plays an important role in climate change by regulating atmospheric carbon dioxide. Sweden’s forest management has led to a decrease in old growth forests. This change in land use can affect SOC levels in these forests. READ MORE

  6. 5. Ozone oxidation of fatty acid thin films: a TIR Raman study

    University essay from KTH/Yt- och korrosionsvetenskap

    Author : Frida Preuss; [2022]
    Keywords : ozone oxidation; TIR Raman; fatty acid; vibrational spectroscopy; thin film formation; ozonoxidation; TIR Raman; fettsyra; vibrationsspektroskopi; skapande av tunna filmer;

    Abstract : Detta examensarbete initierades och handledes av Mellifiq, ett företag som arbetar med rening av luft och vatten, där en applikation är rening av köksfrånluft med ozon. Ozon förhindrar att fettpartiklar i frånluften ansamlas på väggarna i kanalen och värmeväxlaren, vilket leder till högre brandsäkerhet och mer effektiv användning av värmeväxlaren. READ MORE
