1. 16. Utvärdering av sensordata för bedömning av surstötar

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Elijah Selin Norén; [2022]
   Keywords : Försurningsepisoder; försurningsskador; sensorer; vattendrag; organiska syror;

   Abstract : Surstötar är en naturligt förekommande process i sötvattenekosystem. Episoderna kan förvärras av mänsklig aktivitet och kan därför få stor effekt på biota eftersom systemet är mera känsligt under perioder med högflöden. READ MORE

3. 17. Antenna Implants and Feasibility of Performance Limitations : AStudy of Radiation Efficiency on Electrically Small Antenna Implants with Finite Conductivity and Size

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Erik Algarp; [2022]
   Keywords : Antennaimplant; Medical Implant CommunicationSystem; Electrically small antenna; Electric dipole; Magnetic dipole; Fundamental bounds; Performance limits; Radiation efficiency; Conductor loss; Antennimplant; Medical Implant Communication System; Elektriskt små antenner; Elektrisk dipol; Magnetisk dipol; Fundamentala begränsningar; Prestandagränser; Strålningseffektivitet; Metallförlust;

   Abstract : Antenna implants are used to establish a telemetry link to enable wireless data transfer, suitable for telemedicine and other medical applications. Inbody environments with water-based tissues lead to severe power absorption, making signal strength and radiation efficiency challenging yet central performance aspects of antenna implants.

4. 18. Removal Characteristics of Fibrous and Particulate Microplastics : A Study of the Effectiveness of Coagulation-Flocculation- Sedimentation

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Amrith Kumar; [2022]
   Keywords : Coagulation; flocculation; jar test; microplastics; sedimentation; water treatment; Burktest; flockning; koagulering; mikroplaster; sedimentering; vattenrening;

   Abstract : The rapid proliferation of microplastics (MPs) over the last few decades have raised alarms about the major environmental and health impacts posed by this anthropogenic source. The widespread propagation and transport of MP particles in water sources have accelerated the need to study the eco- toxicological impacts as well as the efficacy of various removal mechanisms from these critical water sources.

5. 19. Construction and Validation of a Lab-scaleBorehole Thermal Energy Storage Model

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

   Author : Haoyang Dong; [2022]
   Keywords : borehole heat exchanger; lab-scale model; experimental construction; experiment test; validation; borrhålsvärmeväxlare; labbmodell; experimentell konstruktion; experimenttest; validering;

   Abstract : Borehole heat exchangers are widely used in heat pumps of residential buildings and industrialsystems. It is known as one of the most energy ecient technologies which provides heatingand cooling by using sustainable geothermal energy. The life time of borehole heat exchangerslasts more than 50 years which is longer than combustion boilers. READ MORE

6. 20. Comparing Groundwater Drawdown with Estimated Influence Radius – A Case Study of Infrastructural Projects in Sweden

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Staffan Druid; [2022]
   Keywords : Influence radius; analytical formula; groundwater lowering; sensitivity; Influensradie; analytisk beräkning; grundvattenavsänkning; känslighet;

   Abstract : Infrastructural projects may sometimes require excavation of soils and the groundwater table to be lowered, temporarily or permanently. As there are risks in connection to groundwater lowering, the extent of the affected area is of interest. READ MORE
