   Sammanfattning : AUTISM SYNDROMES IN THREE BEHAVIOURAL PHENOTYPE CONDITIONS A clinical psychiatric study of 76 individuals with Möbius sequence, CHARGE syndrome, and oculoauriculovertebral spectrum Maria Johansson Institute of Neuroscience and Physiology, Child and Adolescent Psychiatry, Göteborg University, Sweden Abstract Objectives: (1) Examine the prevalence of autism syndromes in three different Behavioural Phenotype Conditions (BPCs), (2) examine background and associated factors/conditions, and (3) describe and evaluate diagnostic difficulties in this field of research. Method: As part of multidisciplinary surveys of Möbius sequence (Möbius) (n=25), CHARGE syndrome (CHARGE) (n=31) and oculoauriculovertebral spectrum (OAV) (n=20), the occurrence of autism symptoms was assessed utilizing the DSM-III-R and DSM-IV checklists for autistic disorder (AD), the Autism Diagnostic Interview-Revised (ADI-R), the Childhood Autism Rating Scale (CARS) and the Autistic Behavior Checklist (ABC).

3. 17. A molecular guide to efficient charge transport : Coordination materials for photovoltaic cells

   Författare :Hannes Michaels; Marina Freitag; Aldo Di Carlo; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coordination chemistry; energy conversion; photovoltaics; charge transport;

   Sammanfattning : Emerging solar energy conversion and energy storage technologies play a vital role in solving the present energy crisis and achieving carbon net zero. Currently, they are limited by the use of inefficient, unstable and expensive charge transport materials. LÄS MER

4. 18. Tailing Charges on New Paths : Ultrafast intramolecular charge transfer in chromophores

   Författare :Belinda Pettersson Rimgard; Leif Hammarström; Oliver S. Wenger; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intramolecular charge transfer; interligand electron transfer; electron transfer; proton transfer; concerted electron-proton transfer; Marcus inverted region; solvent; temperature; femtosecond spectroscopy; proton-coupled energy transfer; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

   Sammanfattning : By tailing charges on their paths within a molecule, one can gain fundamental knowledge of their inherent reactivity. The charges, originally residing in their lowest energy configuration, can upon light absorption move across the system, or transfer in between them. LÄS MER

5. 19. Parity Effects in Single Charge Tunneling

   Författare :Magnus Gisselfält; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mesoscopic; single charge tunneling; photon-assisted tunneling; shot noise; SET transistor; parity effect; Andreev tunneling; Coulomb blockade;

   Sammanfattning : The subject of this thesis is single charge tunneling effects, especially parity effects, as they are manifested in quantum mechanical tunneling through a metallic island small enough to cause single electrons to block tunneling of other electrons due to Coulomb interaction. When the island is superconducting the ground state energy depends on the parity of the number of electrons on the island: outside of the condensate there will always be at least one electron contributing to the energy for an odd number of electrons and this will have observable consequences.
