2. 1. Factors influencing emission fluxes and bacterial enrichment in sea spray aerosols : Insights from laboratory and field studies

   Author : Julika Zinke; Matthew E. Salter; Paul Zieger; Rachel A. Foster; E. Douglas Nilsson; Patricia K. Quinn; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sea spray aerosols; eddy covariance fluxes; air-sea-exchange; bacteria; primary biological airborne particles; laboratory studies; field studies; Baltic Sea; North-Eastern Atlantic; Environmental Sciences; miljövetenskap;

   Abstract : Sea spray aerosol (SSA) is one of the major natural aerosol sources and is produced when wave breaking entrains air into ocean surface water, which subsequently breaks up into bubbles. These bubbles rise to the surface and can scavenge biogenic material. READ MORE

4. 2. Contrasting language-in-education policy intentions, perceptions and practice : the use of English and Kreol Seselwa in the Seychelles

   Author : Justin Zelime; Mats Deutschmann; Anders Steinvall; Angeline Mbogo Barrett; Umeå universitet; []
   Keywords : HUMANIORA; HUMANITIES; Code switching; Kreol Seselwa Seychelles Creole ; L2 Medium of Instruction; Post Colonialism; Language Policy; Translanguaging; Bilingualism; Multilingualism; language studies; språkvetenskap;

   Abstract : Many studies have shown that Second Language (L2) Medium of Instruction (MoI) policies in Africa are linked to educational inequity, substandard teaching practice, low literacy skills and poor overall academic performance. In the light of this background, this thesis aims to make a more thorough inquiry into questions related to language-in-education policies, L2 as MoI, and academic success in the Seychelles, a small island nation in the Indian Ocean.

   Keywords : HUMANIORA; HUMANITIES; algal bloom; Baltic Sea; cultural eutrophication; dead zone; waste ecology; environmental degradation; environmental humanities; critical ocean studies; environmental imaginary; environmental value; more-than- human; textual analysis; visual analysis; storytelling; algblomning; Östersjön; kulturell övergödning; bottendöd; avfallsekologi; miljöförstöring; miljövetenskap; kritiska havsstudier; miljömyndighet; miljövärde; mer-än-mänsklig; textanalys; visuell analys; berättande; Historiska studier av teknik; vetenskap och miljö; History of Science; Technology and Environment;

   Abstract : This dissertation researches how perspectives in western industrial societies communicate about and give meaning to environmental degradation through case studies on the causes and effects of cultural eutrophication—namely nutrient pollution, algal blooms, and dead zones—in the Baltic Sea. Utilizing this approach, this dissertation addresses the ecological problems of cultural eutrophication in marine ecosystems by exposing normative claims humans make about the Baltic Sea and its contents as well as detailing how seas that exceed human expectations may offer insights into negotiating differing perspectives, discrepancies in power, and ways of being among humans and non-humans in marine environments.

6. 4. Small-amplitude steady water waves with vorticity

   Author : Evgeniy Lokharu; Vladimir Kozlov; Johan Thim; Tomas Sjödin; Mark Groves; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The problem of describing two-dimensional traveling water waves is considered. The water region is of finite depth and the interface between the region and the air is given by the graph of a function. We assume the flow to be incompressible and neglect the effects of surface tension. READ MORE

7. 5. Studies of the Arctic Ocean sea ice cover and hydrothermal heat fluxes

   Author : Christian Stranne; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oceanography; Arctic climate sensisitvity;

   Abstract : Since reliable ice extent estimates from satellite data became available in 1979 the Arctic sea ice cover has followed a declining long term trend. Over the last decade the decline has accelerated with record low sea ice extents recorded in 2002, 2005, 2007 and 2012. READ MORE
