1. 11. Thermo-physical properties of CO2 mixtures and their impacts on cryogenic carbon capture processes

   Författare :Yuting Tan; Per Alvfors; Lars Nord; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 conditioning; CO2 transport; CO2 storage; CO2 mixtures; CO2 cryogenic; heat exchanger; compressor; property impact; viscosity; thermal conductivity; property model; Koldioxidkonditionering; transport koldioxid; koldioxidlagring; koldioxidblandningar; kryogenisk process; värmeväxlare; kompressor; tillståndsstorheters påverkan; viskositet; värmekonduktivitet; tillstånds-storhets¬modell; Chemical Engineering; Kemiteknik;

   Sammanfattning : Carbon capture and storage (CCS) is one of the most promising technologies that may significantly reduce CO2 emissions. A better understanding of the thermo-physical properties of CO2 mixtures is required for the design and operation of different CCS processes. LÄS MER

3. 12. Filtration System For On-Site Wastewater Treatment : Experiences From Modelling and Experimental Investigations

   Författare :Rajabu Hamisi; Gunno Renman; Anders Wörman; Scholz Miklas; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Land and Water Resources Engineering; Mark- och vattenteknik;

   Sammanfattning : Many on-site wastewater treatment systems in Sweden are not sustainable in terms of treatment efficiency, nutrient recycling and economics. Achieving reliable and sustainable systems to meet on-site wastewater treatment demands requires comprehensive field investigations of the performance of novel technologies. LÄS MER

4. 13. Fängelse, skola, uppfostringsanstalt eller skyddshem? : Åkerbrukskolonien Hall för pojkar år 1876-1940

   Författare :Ulrika Norburg; Bengt Sandin; Roddy Nilsson; Linköpings universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Children; class; criminality; criminal care; delinquency; discipline; masculinity normality; philanthropy; school; training school; visibility and youths; Barn; brottslighet; disciplinering; filantropi; fångvård; klass; maskulinitet; normalitet; skola; synliggörande; ungdomar; uppfostringsanstalt och vanart;

   Sammanfattning : År 1876 inrättades uppfostringsanstalten Hall utanför Södertälje. Anstalten var en av de första anstalterna i Sverige som tog emot pojkar i åldrarna 10-15 år som hade dömts i domstol till att insättas på uppfostringsanstalt. Dessutom tog Hall emot pojkar som låg i riskzonen för att bli brottsliga. LÄS MER

5. 14. Towards sustainability of environmental protection : recovery of nutrients from wastewater filtration and the washing of arsenic contaminated soils

   Författare :Lea Rastas Amofah; Helen French; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

   Sammanfattning : Conventional methods for wastewater treatment and remediation of the sites withcontaminated soils focus on protection of human health, receiving waters and theenvironment. Towards this end, these methods concentrate on the reduction or removal of polluting substances, and therefore, are not well suited for creating resources through the recovery of nutrients, energy and decontaminated soils.

7. 15. Phosphine ligands with triamine functionality - preparation and application in catalysis

   Författare :Magnus Karlsson; Enheten för fysikalisk och teoretisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; water soluble; palladium; amphiphilic; rhodium; Oorganisk kemi;

   Sammanfattning : Incorporation of the triamine, bis(2-diethylaminoethyl) amine as a side chain substituent on triphenylphosphine, (2S,4S)-4-diphenylphosphino-2-diphenylphosphino-methylpyrrolidine (PPM) or (R,R)-3,4-bis(diphenylphosphin)pyrrolidine (Pyrphos) gives the three new amphiphilic ligands N3P, N3PPM and N3-Pyrphos respectively. Because of the triamine functionality the distribution of the ligands and their complexes between water and an organic solvent is controlled by the pH of the aqueous phase. LÄS MER
