1. 1. Techno-Economic Analysis of Dye Separation in Textile Recycling

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : David Lundberg; [2024]
   Keywords : Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

   Abstract : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. READ MORE

3. 2. Exploring alternative surfactants to replace PEG within lipid nanoparticles

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master); Lunds universitet/Bioteknik (CI); Lunds universitet/Bioteknik (master)

   Author : Elina Edidovica; [2024]
   Keywords : Lipid nanoparticle; polyethelyne glycol PEG ; alpha-tomatine; N-hexadecyl beta d-maltoside HDM ; DOPC; DPPC; cholesterol; film hydration; stability study; DLS; Cryo-TEM; SAXS; pharmaceutical formulation; Chemistry;

   Abstract : Over the past decade an increasing amount of studies has demonstrated that PEGylation not only precipitates reductions in drug delivery efficiency but also triggers the immune system to produce antibodies, specifically anti-PEG antibodies. The objective of my thesis is to explore alternative surfactants that could viably replace PEG within lipid nanoparticles. READ MORE

4. 3. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Johanna Bergström; [2023-09-15]
   Keywords : Acid sulfate soil; AS soil; ERT measurements; resistivity; Baltic basin; Swedish west coast; acidification; Tapes transgression;

   Abstract : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. READ MORE

5. 4. Failure Probability and Lifetime Estimation for Industrial Robots : A Logistic Regression and Lifetime Analysis Approach

   University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

   Author : Erik Fahlbeck Carlsson; Martin Herbert; [2023]
   Keywords : Lifetime Analysis; Logistic regression; Prediction; Lifetime estimation; Industrial robots; Livslängdsanalys; Logistisk regression; Prediktion; Livslängdsestimering; Industriella robotar;

   Abstract : The ability to handle and process data for information extraction is getting more and more important. Using extracted data from the business to improve productivity is seen as an important part in developing the business processes. In this thesis, industrial robots and their survival times are analyzed. READ MORE

6. 5. Påverkan av tid och temperatur vid analys av pH i träckprov från häst

   University essay from SLU/Dept. of Clinical Sciences

   Author : Olivia Ahlstedt; Martina Löfgren; [2023]
   Keywords : ekvint; fecesprov; mag-tarmhälsa; metodstudie; pH; provförvaring; provhantering;

   Abstract : Mätning av pH i träck är vanligt förekommande i vetenskapliga artiklar om nutrition och magtarmhälsa på häst. Metoderna för mätning av fekalt pH som beskrivs i litteraturen varierar mellan olika studier vilket gör att det finns en efterfrågan av ett mer standardiserat protokoll för mätning av fekalt pH.
