  1. 21. Novel measure of olfactory bulb function in health and disease

    Författare :Behzad Iravani; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Present neuroimaging techniques are capable of recording the neural activity from all over the brain but the olfactory bulb (OB). The OB is the first olfactory processing stage of the central nervous system and the site of insult in several neurological disorders, particularly Parkinson’s disease (PD). LÄS MER

  3. 22. Potential of Organosolv Lignin Nanoparticles as a Sustainable Flotation Reagent : Towards a Low-Carbon Footprint Mining Industry

    Författare :Katerina Hruzova; Ulrika Rova; Saija Luukkanen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organosolv lignin particles; Nanoparticles; Flotation reagent; Copper recovery; Biokemisk processteknik; Biochemical Process Engineering;

    Sammanfattning : The green transition is driving a steep increase in the demand for minerals, which has put the focus on more responsible and sustainable mining practices as there is a growing pressure on mining operations to minimise their environmental footprint, mitigate risks in neighbouring communities, and decrease the consumption of natural resources. In 2022, mineral froth flotation was used to recover 18 million tonnes of copper from copper ore, accounting for 80% of total copper mine output. LÄS MER

  4. 23. Development of Novel In Situ ESEM Techniques for the Study of Water Interaction with Soft Materials

    Författare :Anna Jansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; environmental scanning electron microscopy; cellulose fibre; water transport; swelling; osmotic shock; yeast cell; in situ; manipulator; water interaction;

    Sammanfattning : The transport of water is central to many applications of soft biomaterials; for example water management in personal care products, controlled drug release in pharmaceuticals and, on a fundamental level, the activities of living cells. Water transport through a material may occur in both liquid and gas phase, and is highly dependent on the microstructure. LÄS MER

  5. 24. Lung and chest wall properties during mechanical ventilation

    Författare :Per Erik Persson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical ventilation; Respiratory mechanics; Esophageal pressure; Positive end-expiratory pressure;

    Sammanfattning : Background: Mechanical ventilation causes injury to the lungs due to high pressures and high volumes. Pressure affecting the lungs, the transpulmonary pressure, needs to be monitored to minimise harmful side effects but then lung and chest wall mechanics need to be separately considered. LÄS MER

  7. 25. CMOS Analog-to-Digital Converters - Analysis, Modeling, and Design

    Författare :Martin Andersson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A high-performance and flexible analog-to-digital converter (ADC), that can be integrated in deep-submicron CMOS technology, is a key building block for reduced size, cost and power consumption of digital communication systems. This dissertation concerns the investigation of particular problems associated with the design of such ADCs. LÄS MER
