    Author : Susann Häggqvist; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Work Environment Management; collaboration; school; pupil; employee; participation; evaluation; health; stress;

    Abstract : The principal aim of this dissertation is empirically todevelop and test a collaboration model for how to operatesystematically with the work environment at school. Ontheoretical grounds, a case is made that collaboration betweendifferent groups (various professions and pupils) should beinvestigated despite different conditions, qualifications andages.

  4. 2. Selective wavelength pupillometry to evaluate outer and inner retinal photoreception

    Author : Aki Kawasaki; Fatima Pedrosa Domellöf; Bertil Lindblom; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pupil; pupil light reflex; melanopsin; photoreceptor; intrinsically photosensitive retinal ganglion cell; oftalmiatrik; Ophtalmology;

    Abstract : PurposeIntrinsically photosensitive retinal ganglion cells (ipRGCs) express a unique photopigment called melanopsin. Capable of direct phototransduction, the ipRGCs are also influenced by rods and cones via synaptic inputs. READ MORE

  6. 4. Superior Underwater Vision in Humans

    Author : Anna Gislén; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; taxonomy; zoogeography; Zoologisk systematik; djurgeografi; Systematic zoology; contrast sensitivity; spatial vision; Accommodation; pupil;

    Abstract : Amphibious vision is accomplished in many animals by special optical and physiological adaptations in the eyes. However, human eyes are considered to be adapted to a life in air since our curved outer cornea – which is used to refract more than two-thirds of the incoming light on land – becomes useless underwater.

  7. 5. Safety and efficacy of intracameral mydriatics in cataract surgery

    Author : Björn Lundberg; Anders Behndig; Charlotta Zetterström; Umeå universitet; []
    Keywords : Ophtalmology; intracameral; mydriatics; pupil; cataract; phacoemulsification; lidocaine; phenylephrine; cyclopentolate; epinephrine; endothelial cell loss; Oftalmiatrik; oftalmiatrik; Ophtalmology;

    Abstract : Background: In order to perform cataract surgery, adequate dilatation of the pupil is essential. This is traditionally achieved by preoperative topical mydriatic eye-drops, commonly cyclopentolate and phenylephrine. This routine has several disadvantages. First, the slow penetration through the cornea delays the onset of mydriasis. READ MORE
