1. 11. Organising matters for the environment: Environmental studies of housing management and buildings

   Författare :Birgit Brunklaus; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; life cycle assessment LCA ; Livscykelanalys; environmental management systems EMS ; field studies; housing management; environmental assessment; buildings; passive house technology; action nets; organisation theory; Miljöteknik; environmental management; Miljövetenskap; Tvärvetenskap; Organisationsforskning;

   Sammanfattning : Buildings give rise to several environmental problems over the whole life cycle. To reduce these, technical measures with focus on energy are commonly used. However, environmental problems are more than energy and cannot be solved with technical measures alone. LÄS MER

3. 12. Use and Development of Diffusive Samplers to Analyse the Fate of Polycyclic Aromatic Compounds, Polychlorinated Biphenyls and Pharmaceuticals in Wastewater Treatment Processes

   Författare :Lijana Augulyte; Patrik L. Andersson; Anna Ledin; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioavailable; biologically activated carbon; PRCs; sampling rate; SPMD; sorption; wastewater treatment; diffusive passive samplers; human pharmaceuticals; municipal sewage treatment plant; organic micropollutants; polycyclic aromatic compounds; PAHs; PCBs; POCIS; Environmental chemistry; Miljökemi;

   Sammanfattning : The efficiency of wastewater treatment systems is commonly measured by the reductions of parameters such as biological oxygen demand (BOD), chemical oxygen demand (COD) and total suspended solids (TSS) and/or reductions in levels of selected macro compounds (e.g. long-chained hydrocarbons and inorganic compounds).

4. 13. Neurochemical regulators of the septohippocampal pathway : role in spatial and aversive learning

   Författare :Elin Elvander Tottie; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Acetylcholine; muscarinic receptor; galanin; serotonin; 5-HT1A receptor; glutamate; NMDA receptor; water maze; passive avoidance; septum; hippocampus; learning; memory; spatial; aversive; emotional; cognition;

   Sammanfattning : The aim of this thesis was to investigate the significance of major neurotransmitters in the septohippocampal pathway for hippocampal-dependent learning and memory. The cholinergic and GABAergic neurons in the medial septal/vertical limb of the diagonal band of Broca area (MS/vDB) projecting to the hippocampus, constitute the septohippocampal pathway, which has been implicated in a number of important functions such as attention, anxietylike behavior and hippocampal-dependent learning and memory.

5. 14. Low-Power Delta-Sigma Modulators for Medical Applications

   Författare :Ali Fazli Yeknami; Atila Alvandpour; Martin Anderson; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : Biomedical electronics has gained significant attention in healthcare. A general biomedical device comprises energy source, analog-to-digital conversion (ADC), digital signal processing, and communication subsystem, each of which must be designed for minimum energy consumption to adhere to the stringent energy constraint.

7. 15. Compact RF Integration and Packaging Solutions Based on Metasurfaces for Millimeter-Wave Applications

   Författare :Abbas Vosoogh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The millimeter-wave frequency range has got a lot of attention over the past few years because it contains unused frequency spectrum resources that are suitable for delivering Gbit/s end-user access in areas with high user density. Due to the limited output power that the current RF active components can deliver in millimeter-wave frequencies, antennas with the features of low profile, high gain, high efficiency and low cost are needed to compensate free space path loss and increase the communication distance for the emerging high data rate wireless systems.
