1. 1. Fungi as a potential solution to microplastic pollution: A qualitative study examining the opportunities and obstacles of implementing mycoremediation in Swedish agricultural soils from a perspective of ecological sustainability

   University essay from Göteborgs universitet/Institutionen för globala studier

   Author : Julia Zajac; [2023-11-08]
   Keywords : mycoremediation; ecological sustainability; sustainable development; microplastics; fungi;

   Abstract : The world is facing microplastic pollution in almost all areas, as a result of increased manufacture and use of plastics in recent years. One of the most highly polluted environments are agricultural soils, which are estimated to contain up to 14 percent of all microplastic pollution. Few effective methods exist to solve this problem.

3. 2. High-Temperature Thermal Energy Storage for Innovative Hybrid CSP/PV Plants : A Comprehensive Design Optimization

   University essay from KTH/Energiteknik

   Author : Lorenzo Centonze; [2023]
   Keywords : ;

   Abstract : By means of a literature review, critical parameters in the context of thermal energy storage systems, particularly packed bed thermal energy storage systems are identified. The goals of this thesis project are to come up with an optimized design for a PBSTES and to evaluate the thermal performance of alternative storage materials derived from byproducts of industrial processes and natural rocks in order to reduce the environmental impact of the designed system.

4. 3. Flexible project management in highly regulated railway signaling projects

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Teresa Talio; [2023]
   Keywords : Signalling; Railway; System development; Systems Engineering; Lean Philosophy; Stage-Gate Process; Signalering; järnväg; systemutveckling; systemteknik; Lean-filosofi; Stage-gate-processen;

   Abstract : Railway is a complex system, with many components that are linked with one another. If a failure occurs in a sub-system, it can affect the functionality and the safety of the whole. Signalling represents a crucial component of the railway system because it ensures safety, and it can optimize capacity on the lines. READ MORE

5. 4. Varnishing of Fiber-based Closures

   University essay from Lunds universitet/Förpackningslogistik

   Author : Nisha Sunil David; [2023]
   Keywords : Varnishing; fiber-based closures; water-based spray coating; packaging; repulpability ; Technology and Engineering;

   Abstract : This research aims to investigate water-based varnishes and technologies to coat fiber-based closures to attain water barrier properties. To ensure recyclability the repulpability of coated and uncoated lids is tested. The research approach is exploratory. READ MORE

6. 5. Quality of Spent Mushroom Compost Amended with Organic Material- Effect on Nutrient Content and Plant Growth

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)
