1. Förutsättningar för hantering av länshållningsvatten från tunnelproduktion i byggandet av Ostlänken : Återanvändning av näringsämnen genom bevattning
Uppsats för yrkesexamina på avancerad nivå,Sammanfattning : When a tunnel is built in rock, a type of water is formed as a residual product. This tunnel wateris formed due to construction processes such as drilling requiring water and groundwater thatinfiltrates into the tunnel. The water can cause environmental damage if it is released directlyinto nature and needs to be treated. LÄS MER
2. Formulation development, rheological characterization, and cosmetic evaluation of gel-creams
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : Oil in water (o/w) emulsions are thermodynamically unstable systems composed of small oil droplets dispersed in a continuous aqueous phase. This means that given enough time, the two phases will separate. Pharmaceutical emulsions are used as a method of administering the Active Pharmaceutical Ingredient (API) for topical applications.

4. Finding ways of optimizing coagulant dosage, for a more sustainable wastewater treatment process
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The wastewater treatment process at Oatly consists of several treatment steps of which, two are chemical treatment steps involving coagulation followed by flotation to remove phosphorous and COD. The coagulant dosage is mainly determined based on the operator’s experience and supported using results from jar tests. LÄS MER
5. Quality of Spent Mushroom Compost Amended with Organic Material- Effect on Nutrient Content and Plant Growth
Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Peat, as a non-renewable growing media, poses environmental concerns due to extraction and decomposition processes, leading to increased greenhouse gas emissions. Alternatives growing media with potential to replace or reduce the use of peat are of great need. LÄS MER
