1. 1. Silicon Germanium heterojunction bipolar transistors : Large-signal modeling and low-frequency noise characterization aspects

   Författare :Staffan Bruce; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Silicon Germanium; SiGe; Heterojunction Bipolar Transistor; HBT; Large-signal modeling; thermal time constant; low-frequency noise: coherence; transimpedance amplifier; Materialvetenskap; Materials science; Teknisk materialvetenskap; Elektronik; Electronics;

   Sammanfattning : In this thesis, aspects of the Silicon Germanium (SiGe) Heterojunction Bipolar Transistor (HBT) are addressed. A physics-based electrical large-signal model including thermal dependence has been developed and is implemented using a commercially available simulator package. LÄS MER

3. 2. Genomic and epigenetic investigations of Silver-Russell syndrome and growth restriction

   Författare :Sara Bruce; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : A combination of genes, their epigenetic regulation, and the environment control the phenotypes of an individual, such as how short or tall one grows. Epigenetics refers to chemical modifications of DNA and histones that regulate gene activity and genome stability, and can take the form of, for example, addition of a methyl group to DNA. LÄS MER

4. 3. Problems of language and communication in children; Identification and intervention

   Författare :Barbro Bruce; foniatri och audiologi Logopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; auditive system and speech; Otorinolaryngologi; audiology; Medicin människa och djur ; Otorhinolaryngology; Interaction; Medicine human and vertebrates ; Intervention; Screening; Language and communication problems; audiologi; hörsel- och talorganen; ADHD; Identification; language development;

   Sammanfattning : This thesis addresses identification and intervention of language and communication problems in children. The issue of identification is addressed in study I by investigating communicative ability in 18-month-old children, and in study II by exploring the prevalence of language and communication problems in children with complex problems, such as attention deficit hyperactivity disorder (ADHD).

5. 4. A Deep Dive into Sediments : Exploring approaches to assess environmental risks and achieving environmental goals in management of contaminated sediments in Sweden

   Författare :Peter Bruce; Clare Bradshaw; Yvonne Ohlsson; Anna Sobek; Sabine Apitz; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sediment; risk assessment; risk evaluation; risk management; contaminants; regulations; weight of evidence; line of evidence; environmental goals; environmental management; guidelines; marin ekotoxikologi; Marine Ecotoxicology;

   Sammanfattning : Contaminated sediments are common, especially near urban and industrialized areas, and they can have negative ecological effects. In three studies, I explore the challenges for environmental management of contaminated sediments, focusing on environmental risk assessment (ERA) in Sweden. LÄS MER

7. 5. Using de novo design proteins to explore tyrosine radicals and cation-π interactions

   Författare :Bruce W. Berry; Cecilia Tommos; Anders Hofer; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tyrosine; radicals; cation-pi interactions; de novo designed proteins; biochemistry; biophysics; Biochemistry; biokemi;

   Sammanfattning : Redox cofactors and amino-acid free radicals play important roles in biology. Although many of the same cofactors and amino acids that form these radicals are found across a broad range of biological systems, identical cofactors can have different reduction potentials. The local environment plays a role in defining these redox potentials.
