1. 1. Regulation of productivity in Trichoplusia ni and Spodoptera frugiperda Sf9 serum-free cultures

   Författare :Karin Calles; Lena Häggström; Gunnel Dalhammar; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Insect cells; BEVS; Spodoptera frugiperda; Sf9; Trichoplusia ni; BTI-Tn-5B1-4; specific productivity; conditioned medium; conditioned medium factors; cell cycle; synchronization; G2 M; Bioteknik; Bioengineering; Bioteknik;

   Sammanfattning : The aim of this work has been to characterize the effects of conditioned medium (CM) on insect cell productivity and physiology in order to get a better understanding about the mechanisms that regulate productivity in serum-free media. Two cell lines have been investigated, Spodoptera frugiperda (Sf9) and Trichoplusia ni (T. ni, BTI-Tn-5B1-4). LÄS MER

3. 2. Impact of autocrine factors on physiology and productivity in Trichoplusia ni serum-free cultures

   Författare :Ulrika Eriksson; Lena Häggström; Per Berglund; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Trichoplusia ni; High Five; insect cells; BEVS; serum-free medium; yeast extract; conditioned medium; autocrine regulation of proliferation; growth factors; cell cycle; metalloproteinase; specific productivity; Bioteknik; Bioengineering; Bioteknik;

   Sammanfattning : The aim of this study was to increase the understanding of the mechanisms regulating cell proliferation and recombinant protein production in serum-free cultures of Trichoplusia ni (T. ni) insect cells.Conditioned medium (CM) was shown to contain both stimulatory and inhibitory factors (CM factors) influencing cell growth.

4. 3. Diffusion of Battery Electric Vehicles : The Role of Total Cost of Ownership

   Författare :Jens Hagman; Sofia Ritzèn; Johan Jansson; KTH; []
   Nyckelord :Total cost of ownership; electric vehicles; e-taxis; vehicle salespeople; Machine Design; Maskinkonstruktion;

   Sammanfattning : Due to their high efficiency, zero tailpipe emissions and possibilities of using renewable electricity, Battery Electric Vehicles (BEVs) have been proposed as a way to alleviate the negative consequences of transport. However, as with other energy-efficient innovations market uptake or diffusion of BEVs have so far been limited. LÄS MER

5. 4. Cost and financing of the sustainability transition of the Swedish road freight transport sector

   Författare :Elmira Parviziomran; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Godstransporter; Hållbar utveckling; Fossila bränslen; Fordon; Kostnader; Finansiering; Batterier; Sustainable development; Electric batteries; Vehicles; Freight and freightage; Fossil fuels; Sustainability transition; Decarbonization; Heavy-duty vehicles; Cost; Financing; Battery; Circular economy; Diesel fuels;

   Sammanfattning : The cost and financing of the road freight sector’s sustainability transition, driven by significant greenhouse gas (GHG) emissions and cost considerations, represent an urgent yet underexplored research focus. This study investigates the costs of fleet replacement with zero-emission powertrains, battery electric vehicles (BEVs) and fuel cell vehicles (FCVs), emphasizing cost variables that have been overlooked in transition research.

7. 5. Electrification of Private Mobility: Driving Patterns, Multi-Car Households and Infrastructure

   Författare :Niklas Jakobsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GPS-measured driving data; destination-based analysis; user-centered analysis; Battery electric vehicles; two-car households;

   Sammanfattning : Electrification of personal vehicles has the potential to significantly reduce carbon emissions. However, a large-scale transition to electric vehicles may be difficult as there are many individuals who collectively need to transition to this technology. LÄS MER
