1. 1. Attention-Deficit/Hyperactivity Disorder (ADHD) Beyond the Young Age : Investigation of the Prevalence of ADHD in Older Adults and the Risk of Age-related Disorders

   Författare :Maja Dobrosavljevic; Henrik Larsson; Ebba du Rietz; Henrik Andershed; Alexandra Philipsen; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ADHD; prevalence; comorbidity; functional impairments; older adults; age-related disorders; dementia; mild cognitive impairment; cardiometabolic disorders; prediction model;

   Sammanfattning : Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder characterized by impairing levels of inattention and/or hyperactivity-impulsivity. Symptoms of ADHD, which typically emerge in childhood, may persist until older age with a substantial adverse impact on health and functionality. LÄS MER

3. 2. The impact of criminal and externalizing behaviors on aging : Long-term associations with health and dementia

   Författare :Carmen Solares Canal; Henrik Larsson; Jonas Persson; Henrik Andershed; Björn Hofvander; Örebro universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Older adults; aging; criminal behavior; externalizing behaviors; violent crime; dementia; Alzheimer s diseases; mental health; physical health; epidemiology;

   Sammanfattning : Previous studies have shown that criminal and other externalizing behaviors are associated with several adverse outcomes, but very little is known about the impact of these behaviors beyond middle adulthood. Few studies have explored how a life-course background of criminal and externalizing behaviors influence aging and more specifically, whether it is associated with the onset and development of different neurodegenerative, mental, and physical health disorders when aging.

4. 3. Electron transport in quaternized cross-linked poly(4-vinylpyridine) films containing trapped redox molecules : experimental and theoretical aspects that concern identification of electron translation mechanisms

   Författare :Henrik Larsson; Michael Sharp; Marcin Majda; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; charge transport; polymer film; Analytical Chemistry; analytisk kemi;

   Sammanfattning : This thesis deals with the identification of electron translation mechanisms in quaternized cross-linked poly(4-vinylpyridine) films containing trapped redox molecules. Experimental aspects, such as the determination of the total amounts of electroactive species within the films, measurements of electrochemical rate parameters and ellipsometric film thickness  evaluation, are discussed together with theoretical models that predict different mechanisms of charge transport.

5. 4. Genetic and environmental factors in the development of externalizing symptoms from childhood to adolescence

   Författare :Henrik Larsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Externalizing symptoms; ADHD; antisocial behavior; psychopathic personality; twin study; development; childhood; adolescence; genetic and environmental factors;

   Sammanfattning : Externalizing problems, such as hyperactivity, impulsivity, aggression, violation of legal or social norms, and delinquent behavior, tend to persist from childhood to adolescence. There are also high levels of comorbidity among supposedly different domains of externalizing problems. LÄS MER

7. 5. Growth of thick GaN layers on sapphire by Hydride Vapour Phase Epitaxy

   Författare :Henrik Larsson; Werner Seifert; Linköpings universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : Gallium nitride (GaN) is a wide bandgap material that is already extensively used in industrial production of optoelectronic devices (light emitters) that operate in the blue and ultraviolet wavelength range. GaN is interesting not only because it has a wide bandgap (3. LÄS MER
