1. 1. Possibilities of using thermal mass in buildings to save energy, cut power consumption peaks and increase the thermal comfort

   Författare :Jonathan Karlsson; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; aggregates; heat capacity; thermal properties; thermal conductivity; thermal inertia; thermal mass; time constant; Energy storage;

   Sammanfattning : The aim of this project was to generate knowledge to enable us to take advantage of heat storage in heavy building structures with regard to as energy savings, better thermal indoor climate, and reduced peak powers. This could include buildings that can function without energy input during cold periods, buildings that give a robust indoor climate without installed cooling, and buildings with good thermal comfort also in case of higher outdoor temperatures resulting from global warming.

3. 2. Breaking the Unbreakable : Exploiting Loopholes in Bell’s Theorem to Hack Quantum Cryptography

   Författare :Jonathan Jogenfors; Jan-Åke Larsson; Fredrik Karlsson; Marek Żukowski; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In this thesis we study device-independent quantum key distribution based on energy-time entanglement. This is a method for cryptography that promises not only perfect secrecy, but also to be a practical method for quantum key distribution thanks to the reduced complexity when compared to other quantum key distribution protocols.

4. 3. Autobiographical Memory : Depending on sensory retrieval cue and gender

   Författare :Kristina Petersén Karlsson; Fredrik Jönsson; Johan Willander; Sverker Sikström; Jonathan Koppel; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; autobiographical memory; sensory retrieval cues; age distribution; phenomenological ratings; latent semantic analysis LSA ; linguistic inquiry word count LIWC ; gender differences; Psychology; psykologi;

   Sammanfattning : In my thesis I raised two questions: Does autobiographical memory differ i) depending on the sensory retrieval cue (Study I and II)? and ii) depending on gender (Study III)?Concerning retrieval cues, three unimodal cues (i.e., photographs, naturalistic sounds and odors) and one multimodal cue (i.e. LÄS MER

5. 4. More than Meets the Eye : Transmedial entertainment as a site of pleasure, resistance and exploitation

   Författare :Karin Fast; André Jansson; Michael Karlsson; Jonathan Gray; Karlstads universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Transmedial; entertainment; world; brand; media convergence; producer; consumer; fandom; power; Media and Communication Studies; Medie- och kommunikationsvetenskap;

   Sammanfattning : Today’s converging entertainment industry creates ‘transmedial’ brand worlds in which consumers are expected to become immersed. Integrated marketing campaigns connected to these worlds encourage various kinds of consumer productivity and invite consumers to partake in brand-building processes. LÄS MER

7. 5. In vitro and in vivo studies on the toxicology of di-n-butyl phthalate (DBP) : Effects on reproductive, endocrine, and immune systems

   Författare :Liselott Källsten; Oskar Karlsson; Paula Pierozan; Jonathan W. Martin; Jorma Toppari; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dibutyl phthalate; Endocrine disrupting chemicals; Male reproductive health; Phthalates; Immunotoxicity; Toxicology; Steroidogenesis; Environmental Sciences; miljövetenskap;

   Sammanfattning : Chemical pollution is an increasing societal problem and has a major impact on human and environmental health. One important source of chemical pollution is plastic, which contains many different compounds with often largely unknown hazards. LÄS MER
