6. Kombinationsbehandling med Lactobacillus och Bifidobacterium vid irritable bowel syndrome
Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)Sammanfattning : Irritable bowel syndrome (IBS) är en av våra vanligaste funktionella tarmsjukdomar med en prevalens på ca 10% värden över. Diagnosen ställs utifrån ROME-kriterierna vilka är ett symptombaserat diagnostiskt verktyg samt uteslutande av andra allvarliga tillstånd. LÄS MER
7. Groundwater Inflow into Fractured Rock Tunnels
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Groundwater inflow is a challenge in construction of tunnels in fractured bedrocks since it affects the safety function of tunnels and leads to potential problems in the surrounding environment, such as subsidence, dropdown of the groundwater table. Quantification of groundwater inflow into the tunnel is also important for design of grouting in the construction of the tunnel. LÄS MER
8. Numerical Simulations of Wave Propagation between a Left-Handed Material and a Right-Handed Material
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The discovery of metamaterials has led to major advances in different fields of physics including optics, microwave engineering and acoustics. Specific to theoretical electromagnetism, the introduction of metamaterials have led to the development of negative-index materials (NIMs) with simultaneous negative permittivity and negative permeability with backward-wave propagation.

9. Framställning av magnetisk polymerkomposit : Stålpulverfylld epoxi med magnetiska egenskaper
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad materialvetenskapSammanfattning : To compete with other manufacturing companies in the market, product design and manufacturing methods need to be improved constantly. To save time and money, there is an advantage if there is a manufacturing plan in place before designing the final product. LÄS MER
10. Metal Removal Efficiency of Five Filter Media Intended for use in Road Stormwater Treatment Facilities
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Roads, buildings, vehicles, and human activities cause spreading of pollutants, which partly end up in stormwater. The pollutant load contains solid particles of various size, hydrocarbons, organics, metals, nutrients, and microorganisms, which can have negative effects on water quality of surface-, coastal- and ground waters.
