1. 11. Non-Linear FE-Analysis of a Composite Action Girder with Coiled Spring Pins as Shear Connectors

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Simon Stahlin; [2019]
   Keywords : composite bridge; composite action; shear connector; coiled spring pins; finite element modeling; samverkansbro; samverkan; skjuvförbindare; spiralbult; finita element modellering;

   Abstract : For bridges to cope with increased requirements such as increased loads, strengthening work can be carried out. In cases where older steel-concrete bridges do not have a composite action, an alternative is to create composite-action to achieve a higher flexural strength. It is introduced by post-installing shear connectors. READ MORE

3. 12. Experimental Characterisation and Modelling of a Membrane Distillation Module Coupled to aFlat Plate Solar Collector Field

   University essay from Högskolan Dalarna/Energiteknik

   Author : David d’ Souza; [2018]
   Keywords : Solar thermal; solar desalination; membrane distillation; permeate gap membrane distillation; spiral-wound module;

   Abstract : An experimental characterisation of a pre-commercial spiral wound permeate gap membrane distillation module was carried out to test its performance at different operating conditions for the purpose of seawater desalination. The experimental setup consisted of a flat plate solar collector field indirectly coupled to the permeate gap membrane distillation module via an inertia tank. READ MORE

4. 13. Effect of Surface roughness for Hydro Turbine Step-up Efficiency

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Ermias Beraki; [2018]
   Keywords : Hydropower; Surface roughness; Hydro Turbine; Step-up Efficiency; IEC 62097 standard; Prototype and Model;

   Abstract : The energy produced by the flow of water is known as hydropower. It is an easily accessible and available source of energy in large quantity in the form of, rivers, lakes, streams and runoffs around the world. Hydropower is dependent upon hydrological cycle hence; this beneficial characteristic of hydropower makes it a renewable source of energy. READ MORE

5. 14. Membrane screening to identify optimal properties when separating organic matter from Bolmen water

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Olivia Söderman; [2017]
   Keywords : natural organic matter; ultrafiltration; nanofiltration; drinking water; membrane technology; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Chemistry;

   Abstract : In many places across the northern hemisphere, drinking water treatment plants (WTPs) need to avert the effects of deteriorating quality in surface water sources caused by increasing lev-els of natural organic matter (NOM). The two major factors responsible for this phenomenon, also called brownification, are the greenhouse effect and changes in soil acidification. READ MORE

6. 15. Role of state weakness in customary conflict resolution : Case of Kenya and Tanzania

   University essay from Uppsala universitet/Institutionen för freds- och konfliktforskning

   Author : Andrei Lahunou; [2016]
   Keywords : Ebharaza; Baraza; CCR; ADR; Africa;

   Abstract : The only way to resolve existing conflicts, mitigate consequences and reduce risks of their reoccurrence is to have efficient instrument for justice delivering.
