2. 1. Greenhouse gas emissions from rewetted extracted peatlands in Sweden

   Author : Sabine Jordan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Peat extraction for horticultural purposes and energy production has a long tradition in Northern Europe. Related drainage activities directly affect the greenhouse gas (GHG) balance due to oxidative peat decomposition and denitrification, with concomitant emissions of carbon dioxide (CO₂) and nitrous oxide (N₂O). Rewetting, i.e. READ MORE

4. 2. Assessing the longitudinal trend of POP concentrations in humans using high-throughput sample preparation methods developed for low-volume samples

   Author : Jordan Stubleski; Anna Kärrman; Samira Salihovic; Petr Kukucka; Jean-Francois Focant; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Longitudinal trends; human biomonitoring; POPs; PFASs; high-throughput solid phase extraction; high-resolution mass spectrometry; tandem mass spectrometry;

   Abstract : Human exposure to anthropogenic persistent organic pollutants (POPs) and their related effects on human health widely vary from person to person, making population-based risk assessment difficult.This thesis aimed to evaluate how individual changes and implemented re-strictions in POP production influenced human exposure.

5. 3. Numerical modelling of highly swirling flows in a cylindrical through-flow hydrocyclone

   Author : Jordan Ko; KTH; []
   Keywords : Technology; Hydrocyclone; fractionation; turbulence modelling; swirl flow; fluent; CFX; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Three-dimensional turbulent flow in a cylindrical hydrocyclone is considered and studied by means of computational fluid dynamics using software packages CFX and Fluent. The aim has been to identify the methods that can be used for accurate simulation of the flow in three-dimensional configurations in hydrocyclones at high swirl numbers. READ MORE

6. 4. Terrain Modelling with GIS for Tectonic Geomorphology : Numerical Methods and Applications

   Author : Gyözö Jordan; Ulf Qvarfort; Tsehaie Woldai; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik; Environmental engineering; Miljöteknik;

   Abstract : Analysis of digital elevation models (DEMs) by means of geomorphometry provides means of recognising fractures and characterising the morphotectonics of an area in a quantitative way. The objective of the thesis is to develop numerical methods and a consistent GIS methodology for tectonic geomorphology and apply it to test sites. READ MORE

7. 5. Blinded by the light : developing models of settlement and mobility with the use of spectroscopy and exploratory methods

   Author : Mattias Sjölander; Philip I. Buckland; Johan Linderholm; Peter Jordan; Umeå universitet; []
   Keywords : HUMANIORA; HUMANITIES; archaeology; hunter-gatherer; spectroscopy; chemometrics; quartz; quartzite; bifacial; lithics; geoarchaeology; exploratory; spatial analysis; modelling; arkeologi; jakt- och fångstfolk; spektroskopi; kemometri; kvarts; kvartsit; bifacial; flathuggen; geoarkeologi; rumslig analys; modellering; Archaeology; arkeologi; environmental archaeology; miljöarkeologi;

   Abstract : In this thesis an exploratory approach has been used to study settlement and mobility among hunter-gatherer societies in Northern Sweden during the 2 000 – 0 BC period. The focus has been on developing the topics of bifacial point use and raw material management of quartzand quartzite materials. READ MORE
