  1. 6. Control of early development of the lens and the retina

    Författare :Tanushree Pandit; Lena Gunhaga; Paola Bovolenta; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lens; retina; BMP; FGF; chick; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : The nervous system is composed of two separate compartments, the central and the peripheral nervous system. The peripheral nervous system (PNS) composed mainly of sensory organs transmits sensory information to the central nervous system (CNS) comprising the brain and the spinal cord. LÄS MER

  3. 7. Evolution of Vertebrate Eyes: a study on lens suspension and optical proterties

    Författare :Ola Gustafsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; evolution; eye; fish; crystalline lens; lens suspension; multifocal optical systems; Agnatha; Actinopterygii; Chondrichthyes; Vertebrate; Sarcopterygii;

    Sammanfattning : Many fishes have well-developed visual systems with color vision capabilities. The crystalline lens is the major refractive element in a fish eye since the cornea is optically inactive underwater. A typical fish eye has a large pupil and a lens of short focal length, features that increase light gathering ability. LÄS MER

  4. 8. Specification of the lens and olfactory placodes and dorsoventral patterning of the telencephalon

    Författare :My Sjödal; Juha Partanen; Umeå universitet; []
    Nyckelord :telencephalon; olfactory; lens; BMP; RA; FGF; Wnt; development; placode; gradient; chick; nervous system; dorsoventral; medicinsk utvecklings- och neurobiologi; Developmental Neurosciences;

    Sammanfattning : The vertebrate nervous system is a highly complex and intriguing structure with diverse functions. To understand the functional nervous system, we first have to be aware of how it is assembled during development. LÄS MER

  5. 9. Knowing the Ropes in Open Innovation : Understanding Tensions through a Paradox Lens

    Författare :Ioana Stefan; Lars Bengtsson; Marcel Bogers; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tensions; open innovation; paradox of disclosure; value co-creation; value capture; openness; appropriability; intellectual property rights; misappropriation; paradox lens; spänningar; öppen innovation; paradox om avslöjande; samskapande av värde; värdefångst; öppenhet; immateriella rättigheter; idé missbruk; paradoxteori lins; Intelligent industri; Intelligent Industry; Industriell ekonomi och organisation;

    Sammanfattning : The fundamental paradox of disclosure suggested by Kenneth Arrow represents a challenge in contemporary open innovation settings. Potential negative outcomes of this paradox – e.g. misappropriation of ideas – are still not fully avertable. LÄS MER

  7. 10. Identity, Old(er) Age and Migrancy : A Social Constructionist Lens

    Författare :Laura Machat-From; Sandra Torres-Örsten; Lars Andersson; Finnur Magnússon; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; identity; migrancy; old age; older migrants; social constructionism; ethnicity; ageing; identity categories; social positions; identity negotiation; identitet; invandrarskap; hög ålder; utrikesfödda äldre; äldre invandrare; socialkonstruktionism; etnicitet; åldrande; identitetskategorier; sociala positioner; identitetsförhandling;

    Sammanfattning : ldentity research in relation to ethnicity and migration has tended to focus an younger people whilst identity research in relation to ageing and old(er) age has not focused an migrants. This inadvertent mutual neglect has led to a lack of identity research that examines the identity categories of old(er) age and migrancy together, a lacuna that this dissertation aims to redress.
