  1. 1. Modulation of Neuronal Functions : the Role of SLC10A4

    Author : Kalicharan Patra; Klas Kullander; Håkan Aldskogius; Per Svenningsson; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dopamine; acetylcholine; central nervous system; neuromuscular junctions; electrophysiology; monoamine; synaptic transmission; neuromodulation; Neuroscience; Neurovetenskap;

    Abstract : Mental health of a person depends on the correct functioning of the brain. The brain and the spinal cord contain many types of cells, of which one important type are called the neurons. Neurons are special in the way they connect to each other to form large networks. READ MORE

  2. 2. On Functional Tolerances in Machine Design

    Author : Rikard Söderberg; Chalmers University of Technology; []
    Keywords : loss functions; tolerance chains; quality loss; computer aided tolerancing; manufacturing cost; functional tolerances; quality; tolerances;

    Abstract : This thesis describes a method that allows tolerances on critical dimensions to be assigned with respect to both quality and manufacturing cost. To be able to quantify and include customer needs in the process of assigning tolerances, the concept of functionality loss is used. READ MORE

  3. 3. The Face of Sleep Loss

    Author : Tina Sundelin; John Axelsson; Clare Anderson; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; sleep loss; sleep deprivation; face perception; interpersonal perception; attractiveness; tiredness; Psychology; psykologi;

    Abstract : Sleep deprivation has been studied for over a century, providing knowledge about the benefits of sleep for many physiological, cognitive, and behavioural functions. However, there have only been anecdotal indications about what a tired or sleep-deprived person looks like, despite the fact that appearance influences not only how other people perceive a person but also how they evaluate them and behave towards them.

  4. 4. Effects of Specific Cochlear Pathologies on the Auditory Functions : Modelling, Simulations and Clinical Implications

    Author : Amin G. Saremi; Stefan Stenfelt; Steve Elliott; Linköpings universitet; []
    Keywords : Auditory modeling; cochlear mechanics; sensorineural hearing impairment; age-related hearing loss; noise-induced hearing loss; inner ear pathologies;

    Abstract : A hearing impairment is primarily diagnosed by measuring the hearing thresholds at a range of auditory frequencies (air-conduction audiometry). Although this clinical procedure is simple, affordable, reliable and fast, it does not offer differential information about origins of the hearing impairment. READ MORE

  5. 5. On noise and hearing loss : Prevalence and reference data

    Author : Magnus Johansson; Stig Arlinger; Einar Laukli; Linköpings universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; irreversible occupational disease; noise-induced hearing; noise-induced measurements OAE ; spontaneous otoacoustic emissions SOAE ; transient evoked otoacoustic emissions TEOAE ; distortion product otoacoustic emissions DPOAE ; Audiology; Audiologi;

    Abstract : Noise exposure is one of the most prevalent causes of irreversible occupational disease in Sweden and in many other countries. In hearing conservation programs, aimed at preventing noise-induced hearing loss, audiometry is an important instrument to highlight the risks and to assess the effectiveness of the program. READ MORE
