  1. 1. Optics for Low Vision Enabling

    Författare :Jörgen Gustafsson; Certec - Rehabiliteringsteknik och Design; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Eccentric viewing; Low vision optics; Low vision rehabilitation; People with low vision; Preferred retinal; locus PRL ; Resolution; Visual acuity; Ophtalmology; Medicinsk teknik; Medical technology; Rehabilitering medicinsk och social ; rehabilitation; revalidation; kinesitherapy; Oftalmologi; Physical medicine; Contrast sensitivity; Detection; Eccentric correction; CFL ; Central visual field loss; Central scotoma; Aberrations; Astigmatism;

    Sammanfattning : For people with central visual field loss, eccentric vision is all that they have to rely on. Even for those who learn how to correctly utilize their eccentric vision, it will never be as good as the central for two entirely different reasons: the off-axis optics of the eye can result in large refractive errors, and the low function of the peripheral retina.

  3. 2. Tumor-targeted superantigens for experimental immunotherapy of human leukemia/lymphoma

    Författare :Cecilia Weigelt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; SAg; SEA; SEAm; HLA class II; TCR; CFL; SDCC; cytotoxicity; TNF a; IFN g; mAb; PA-SEAm; anti-CD19-Fab-SEAm; B-CLL; B-NHL; AML; CML; immunotherapy; Onkologi; Oncology; Onkologi; Clinical Immunology; klinisk immunologi;

    Sammanfattning : Bacterial superantigens (SAgs) have the property of stimulating high proportions of T cells expressing certain TCR Vβ sequences. The SAg first binds with high affinity to HLA class II molecules on the target cell and then stimulates the T cell to produce cytokines and to become cytotoxic. LÄS MER

  4. 3. Domestication effects on foraging behaviour : consequences for adaptability in chickens

    Författare :Christina Lindqvist; Per Jensen; Björn Forkman; Linköpings universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Etologi; chicken; domestication effects; behaviour; red jungle fowl RJF ; contrafreeloading CFL ; egg production; Ethnology; Etnologi;

    Sammanfattning : The main aim of this thesis was to study domestication effects on foraging behaviour in chickens and to investigate whether and how domestication and selection for high production have influenced adaptability in chickens. Two domestic strains of chickens (egg layers and meat type chickens) and their wild ancestor, the red jungle fowl (RJF) were compared in different test situations with respect to foraging behaviour and adaptability.

  5. 4. Improving Peripheral Vision Through Optical Correction and Stimulus Motion

    Författare :Peter Lewis; Peter Unsbo; Linda Lundström; Jörgen Gustafsson; Michael Crossland; Linnéuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; absolute central scotoma; central visual field loss; eccentric viewing; preferred retinal locus; open-view aberrometer; off-axis refractive errors; eccentric correction; dynamic visual acuity; spatial contrast sensitivity; temporal contrast sensitivity; spatio-temporal contrast sensitivity; Optometry; Optometri; Biomedical Sciences; Biomedicinsk vetenskap;

    Sammanfattning : The loss of central vision subsequent to macular disease is often extremely debilitating. People with central field loss (CFL) must use other peripheral areas of the retina in order to see; areas with inferior resolution capacity, which are also affected by off-axis optical errors.

  7. 5. Enhancing intercultural communication in teaching chinese as a foreign language : An action research study

    Författare :Wei Hing Ip; Shui Duen Chan; Xu Shi; Yuet Hung Cecilia Chan; Högskolan Dalarna; []
    Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Intercultural communication; Chinese as a foreign language education; language acquisition; action research; flipped classroom approach; culture in language learning; Intercultural Studies; Interkulturella studier;

    Sammanfattning : Over the past few decades, the rapid development of information communication technology, internationalization and globalization worldwide have required a shift in the focus of Chinese as a foreign language (CFL) towards competence in intercultural communication in which the role of culture in the acquisition of CFL and in the pragmatic use of the language is emphasized and promoted. However, most of the current research in this academic area remains only on a theoretical level. LÄS MER
