1. Comparison of drone ecology and behavior between Apis mellifera mellifera and the hybrid Buckfast in southwestern Sweden
Master-uppsats, Högskolan i Skövde/Institutionen för biovetenskapSammanfattning : Most research on the biology of the western honey bee (Apis mellifera) focuses on the worker bees, but knowledge about drones is lacking despite their important role in mating with a virgin queen. Available information about their ecology and behavior are mainly based on direct observations in need of intensive experience and knowledge about honey bees. LÄS MER
2. Design of high performance buildings : Vulnerability of buildings to climate change from an energy perspective
Master-uppsats, KTH/Hållbara byggnaderSammanfattning : The challenge of climate change is twofold: to mitigate (prevent) the causes of climate change and to prepare (adapt) to the inevitable effects and consequences. Building and construction are key sectors for decarbonisation (mitigation). LÄS MER
3. Orsaker till dystoki hos marsvin i Sverige
Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical SciencesSammanfattning : Marsvin är populära sällskapsdjur som tros ha blivit domesticerade redan på 500–1000-talet. Marsvin blir könsmogna tidigt, honorna vid cirka två månaders ålder och hanarna vid cirka tre månaders ålder. Marsvinshonor är polyöstrala med en cykel på 15–17 dygn där östrus varar i 6–11 timmar.

4. Byggnaders potential för flexibilitet på elnätet : En lönsamhetskalkyl av ett batterilager vid utförandet av flexibilitetstjänster
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomiSammanfattning : This master thesis examines if a battery energy storage installed in an apartment building with PV production can be a profitable investment and how it should be used. By modelling different types of applications such as peak shaving, increasing self-consumption and primary frequency reserves, the most profitable application for the battery storage can be found.

5. Heterogeneous catalytic reactions studied with transient gas supply and event-averaged ambient pressure x-ray photoelectron spectroscopy
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for NanoscienceSammanfattning : CO oxidation over Pd(100) is studied with ambient pressure x-ray photoelectron spectroscopy (APXPS). Cyclic gas composition pulsing of the CO:O2 ratio, combined with a new method using software based event-averaging by image recognition over many pulses, is used to improve the signal-to-noise ratio substantially.
