1. 1. Asymmetric 1,3-Dipolar Cycloaddition Reactions of Azomethine Ylides, Thiocarbonyl Ylides, and Nitrones

   Författare :Staffan Karlsson; KTH; []
   Nyckelord :;

   Sammanfattning : This thesis describes the development of methods for thepreparation of chiral non-racemic substituted pyrrolidines,tetrahydrothiophenes, and isoxazolidines. This has beenaccomplished by using asymmetric intermolecular 1,3-dipolarcycloaddition reactions of azomethine ylides, thiocarbonylylides and nitrones, respectively, with variousdipolarophiles.

3. 2. Older people`s public health care and social services : Functional ability, health complaints, agreement in needs assessment and care satisfaction

   Författare :Staffan Karlsson; Ingalill Rahm Hallberg; Anna-Karin Edberg; Albert Westergren; Kenneth Asplund; Institutionen för hälsovetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : The overall aim was to describe and compare functional ability and health complaints of older people receiving municipal care in relation to housing and informal care, and factors associated with medical health care, municipal care and informal care. Further, the aim was to investigate agreement in needs assessments between personnel and older people and to investigate care satisfaction and health-related quality of life among older people receiving municipal care and services.

4. 3. The Internal Flow in Freezing Water Droplets

   Författare :Linn Karlsson; Staffan Lundström; Anna-Lena Ljung; Jasmina Casals-Terré; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Sammanfattning : The aim of this work has been to study the internal flow in freezing water droplets on a cold surface and to investigate the different heat transfer mechanisms involved. This is an interesting topic with a great number of applications, specifically in areas where the prevention of unwanted icing is important, e.g. LÄS MER

5. 4. From Fossil To Fact : The Denisova Discovery as Science in Action

   Författare :Mattis Karlsson; Eva Hemmungs Wirtén; Martin Fredriksson; Andreas Nyblom; Staffan Bergwik; Linköpings universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; Actor network theory; aDNA; ANT; Denisovan; Denisova human; Denisova hominin; DNA; Knowledge; Bruno Latour; Science; Science in action; STS; Wikipedia;

   Sammanfattning : From Fossil to Fact: The Denisova Discovery as Science in Action is a study of the (actor) networked relations that make and shape science through the case of the discovery of the Denisova human.In 2010, Nature published the article “The complete mitochondrial DNA genome of an unknown hominin from southern Siberia”, the article revealed the results of mtDNA sequencing of a fossilised finger bone excavated from the Denisova Cave in Siberia, showing that the fossil belonged to an individual of a previously unknown type of humans, the Denisovans.

7. 5. Cross-linked Profilin:actin - A tool to study actin dynamics in non-muscle cells

   Författare :Staffan Grenklo; Roger Karlsson; Dan Lindholm; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actin dynamics; profilin; actin; Profilin-actin complex; Cell motility; synaptic vesicle trafficing; Far western; fluorescence microscopy; Cell biology; Cellbiologi;

   Sammanfattning : The microfilament system, consisting of actin and a number of auxiliary proteins, is fundamental for cell motility. Its dynamic organization depends on receptor-mediated signals, leading to rapid polymerizations and depolymerizations of actin. LÄS MER
