2. 16. A Systems Thinking Approach to Computational Thinking in Education

   Author : Ali Hamidi; Anita Mirijamdotter; Marcelo Milrad; Fisnik Dalipi; Sadaf Salavati; Daniel Spikol; Linnéuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

   Abstract : In today's rapidly changing world, the acquisition of essential skills is crucial for the success of young individuals. Among these skills, computational thinking (CT) plays a vital role in problem-solving and adapting to the complex and evolving demands of the 21st century. READ MORE

4. 17. Diagenesis and Reservoir-Quality Evolution of Paralic, Shallow Marine and Fluvio-lacustrine Deposits : Links to Depositional Facies and Sequence Stratigraphy

   Author : Osama Ahmed Hlal; Sadoon Morad; Hans Annersten; J. Marcelo Ketzer; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sandstone; Diagenesis; paralic; shallow marine and fluvio-lacustrine; reservoir quality; sequence stratigraphy; Solid earth geology and petrology; Berggrundsgeologi och petrologi;

   Abstract : Linking diagenesis to depositional facies and sequence stratigraphy enables better prediction of spatial and temporal distribution of diagenetic alterations, and thus of evolution of reservoir quality in sandstones. This thesis demonstrates that employing this approach is possible because depositional facies and sequence stratigraphy can provide useful information on parameters controlling the near-surface diagenesis, such as changes in: (i) pore-water chemistry, (ii) residence time of sediments under certain geochemical conditions, (iii) detrital composition and proportion of extra- and intra-basinal grains, and (iv) types and amounts of organic matter.

5. 18. An Exploration of Information Inadequacy: Instances that Cause the Lack of Needed Information

   Author : Miranda Kajtazi; Darek Haftor; Anita Mirijamdotter; Marcelo Milrad; Sören Brier; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; information; information inadequacy; information lack; information overflow; hermeneutic approach; grounded theory approach; Informatics; computer and systems science; Informatik; data- och systemvetenskap; Information Systems; Informatik;

   Abstract : Information is one of the most essential resources in our contemporary societies, as it guideshuman thinking, planning and subsequent actions, which in turn generates consequencesthat are desired or not. The Lehman Brothers bankruptcy in 2008, the tsunami in Indonesiain 2004, the Space Shuttle Challenger destruction in 1986 are just three instances ofdramatic situations, emerging continuously, where information plays a crucial role.

6. 19. Parameters Controlling Distribution of Diagenetic Alterations within Fluvial and Shallow Marine Sandstone Reservoirs : Evidence from the Libyan Basins

   Author : Muftah Khalifa; Hemin Koyi; Joao Marcelo Medina Ketzer; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Diagenesis; Structural setting; Depositional facies; Basin thermal history; Ther- mal Hot basinal brines; Fluid inclusions; Raman Spectrometry; Stylolites; Hydro-carbon migration; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

   Abstract : This thesis demonstrates that geological setting, depositional facies, open system flux of hot basinal brines and descending of shallow waters have a strong impact on the distribution of the diagenetic alterations within continental and paralic/shallow marine sandstones which in turn control the quality and heterogeneities of the reservoirs.Geological setting controls the mineralogical and textural maturity of sandstone, whereas depositional facies control the pore water chemistry (marine, brackish or meteoric), sedimentary texture and sand body geometry.
