This study examines the consequences of variation in the laying and hatching date for the time of metamorphosis in the common frog Rana temporaria. Field data are presented showing that eggs laid early tend to take longer to develop. Thus, the time advantage for early eggs is reduced at the time of hatching. There was an among-year variation in this phenomenon; it was not manifest in a phenologica
Catalysts belonging to the Sb-V-O system were prepared with various Sb/V ratios and were used for propane ammoxidation to acrylonitrile. XRD patterns of freshly prepared samples show those with excess vanadia to consist of V2O5 and SbVO4, while SbVO4 and α-Sb2O4 are constituents in the samples with a Sb/V ratio above unity. High rate and selectivity for propylene formation at low conversion are ch
C4b-binding protein (C4BP) is a potent inhibitor of the classical pathway of the complement system. This large plasma glycoprotein consists of seven identical a- chains and a unique b-chain held together by disulphide bridges. Both types of subunits are composed almost exclusively of complement control protein domains (CCPs). Using homology-based computer modelling and mutagenesis of recombinant p
Quaternary glacial stratigraphy and relative sea-level changes reveal at least four expansions of the Kara Sea ice sheet over the Severnaya Zemlya Archipelago at 79 degrees N in the Russian Arctic, as indicated from tills interbedded with marine sediments, exposed in stratigraphic superposition, and from raised-beach sequences that occur at altitudes up to 140 m a.s.l. Chronologic control is provi
Streptomyces is the largest genus in the phylum Actinobacteria, known for their complex life cycle and secondary metabolite production. The model bacterium Streptomyces coelicolor grows _lamentously by tip extension and hyphal branching. The hyphal tip is highly organised, with various structural proteins forming a large assembly termed the polarisome. An essential protein, DivIVA, localises to th
Under hösten 2016 utlystes en sluten arkitekttävling om ett nytt kulturhus Bergsjön. Bergsjön är en stadsdel i utkanten av nord-östra Göteborg. Många upplever området som isolerat från resten staden både fysiskt och socialt. Bebyggelsen, som i stort sett är helt intakt från 60-och 70-talet, speglar de dåvarande idealen och bjuder på såväl möjligheter som utmaningar. Samtidigt ligger stadsdelen i mDuring the fall in 2016 the city of Gothenburg announced a competition for a new house of culture located in Bergsjön. Bergsjön is a district in the north east part of the city. A lot of people view the area as isolated from the rest of the city, both physically and socially. The near intact development from the 60s and 70s, reflect the ideals of the time which means both great possibilities and c
In forest biomass estimations, three dimensional (3D) canopy structure data derived from images captured by unmanned aerial vehicles (UAVs), also known as drones, has shown potential due to the flexibility and cost efficiency of the method. However, little research has been done for its applicability in bioenergy forest. In this study, a method was developed with the purpose of remotely estimating
During the second half of August and the first part of September 2017, I radiotracked several European nightjars (Caprimulgus europaeus) around the Stensoffa area in Southern Sweden. Several locations were taken for each bird each night, including diurnal roost and nocturnal points composed by flying and resting behaviours. Being a long-distance migrator already on the way south during autumn migr
We aim to reinforce the importance of more qualitative empirical studies researching the particularities of co-creation efforts, in the context of new, ambiguous mutations of work and organization generated by internet technologies. While answering our research question we will look into personal accounts referring to the individual’s experience of volunteering for Mozilla, and we will contribute
The demand for renewable energy is constantly increasing and in order to compete with other sources of energy the wind energy output has to increase. The power output from wind turbines are highly dependent on the swept radius of rotor blades. Increasing the length of the rotor blades will increase the weight of the blades, resulting in higher demands of the structural performance, but also introd
Tre av WSP Sverige AB genomförda geotekniska undersökningar har studerats. Samtliga är lokaliserade i Skåne. Projekten har valts i syfte att skapa en övergripande förståelse för hur geologin i Skåne påver-kar geoteknikers metodval och arbetssätt i förhållande till aktuell konstruktion. Geologin i Skåne skiljer sig från övriga Sveriges. Bergrunden är i nordvästra Skåne kristallin och i sydvästra SkThree geotechnical investigations made by WSP Sverige AB have been studied. All are located in Scania, Sweden. The projects have been studied in order to create an overall understanding of how the geology of Scania affects the geotechnical engineer choice of methods and approach in relation to the current construction. The geology of Scania is distinct from the rest of Sweden. The bedrock in the n
We have extended our knowledge about the complexity that exists in the marketing of countries. With sweden.se as a case, we have investigated how nation branding is actually managed from a sender perspective. We have analysed which desirable values the Swedish public organization NSU (National Board for Promotion of Sweden Abroad) communicate through the website sweden.se. The results we have ar
Under 2015 steg andelen konsumenter som handlat på mobilen från 16 % till hela 42 %. Ökningen kan bero på att hemsidor blir mer mobilanpassade. Trots det finns det fortfarande en del användare som uppfattar det som mindre säkert att handla på mobilen i jämfört med på en dator. Förtroenden för e-handel skapas i flera led, där gränssnittet bara en del som påverkar kundens tillit. Detta projekt gjord
I Sverige finns det idag mellan 400 000 – 500 000 geoenergianläggningar och det uppskattas att nettotillskottet energi från geoenergianläggningar är ungefär 18 – 20 TWh per år. Geoenergianläggningar använder markens översta 300 – 500 metrar för att utvinna värme eller kyla. Vid anläggning av geoenergisystem kan man använda olika borrtekniker, mer eller mindre lämpliga beroende på olika geologiska There are about 400 000 – 500 000 shallow geothermal energy systems in Sweden and every year the net additions of energy from geothermal energy systems are about 18 – 20 TWh. Usually it is the upper 300 – 500 meters of the ground that are used for extracting heat or cold from cored strata. When constructing a shallow geothermal energy system, there are different drilling techniques available for u
