  1. 1. DIFFERENCES ON THE IMPACTS AND ORIGINS OF POLLEN IN FOUR MAJOR SWEDISH CITIES BETWEEN 2014 AND 2019

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Jean-Patrick Ridet-Lagorce; [2024-02-12]
    Nyckelord :Pollen; Allergy; Antihistaminic; Airborne transport; Geographical origins;

    Sammanfattning : Allergies are widespread in the world and coming from various sources, one of the causes being airborne allergens and especially, pollen. The negative impact of pollen is enhanced by pollution and climate change which are some of the biggest issue humankind is facing today. LÄS MER

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Rosetta Maglio; [2024]
    Nyckelord :Finite element method; Rat brain traumatic brain injury; Rat brain finite element model; Strain; Strain rate; Product of strain and strain rate; Rotational direction; Rotational duration; Injury prediction; Finita elementmetoden; Råtthjärnans finita elementmodell; Belastning; Belastningshastighet; Produkten av belastning och belastningshastighet; Rotationsriktning; Rotationstid; Skadeförutsägelse;

    Sammanfattning : A traumatic brain injury is usually caused by a direct impact to the head and is a common cause of disability and death all around the world. The most effective method to predict brain injury today, is to use a finite element head model. LÄS MER

  4. 3. Skalningseffekter av medelstora pölbränder i syrereducerad miljö

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Tim Hemel; Philip Frenander; [2024]
    Nyckelord :Sökord: syrereducerad atmosfär; medelstora pölbränder; skalningseffekter. Key words: hypoxic air; oxygen reduced atmosphere; medium pool fire; scaling effects; LOC; yields.; Technology and Engineering;

    Sammanfattning : This bachelor's thesis focuses on how scaling the pool diameter affects flammable liquids in an oxygen reduction system (ORS). This topic in the study of pool fire behavior in hypoxic air has been only lightly discussed in previous literature. Therefore, the goal of this thesis work is to further broaden the understanding of hypoxic air. LÄS MER

  5. 4. Hur kan kontor bli hem? - Konvertering av kontorslokaler till bostäder ur ett fastighetsägarperspektiv

    Master-uppsats, Lunds universitet/Fastighetsvetenskap

    Sammanfattning : The Swedish office markets especially in the three major cities Stockholm, Gothenburg, and Malmö have experienced increased vacancy rates in recent years. One key factor behind this is employees' preferences post the Covid-19 pandemic. LÄS MER

  7. 5. Effects of natural aging and low strain-rate on mechanical properties of aluminium alloy sheets used in automotive industry

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Amirhossein Gholami; Ali Abedisamarin; [2024]
    Nyckelord :Ageing. AA6014. AA6016;

    Sammanfattning : These days, lightweight materials such as aluminum alloy sheets, especiallythose in the AA6xxx series, are in high demand for use inthe automotive industry. During natural aging, the properties of aluminummay undergo significant changes due to the diffusion of atomswithin the crystal structure, impacting the strength and formabilityof aluminum sheets.
