1. 6. Formulation development, rheological characterization, and cosmetic evaluation of gel-creams

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

   Author : Carl Pontén; [2024]
   Keywords : Rheology; Texture analysis; Viscometry; Semisolids; Design of Experiments; Critical Process Parameters; Critical Quality Atttibutes; Pharmaceutical Technology; Technology and Engineering;

   Abstract : 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.

3. 7. 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. 8. The active phase of Pt(110) during catalytic CO oxidation

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Hira Qazilbash; [2024]
   Keywords : Physics and Astronomy;

   Abstract : CO oxidation is an important topic in heterogeneous catalysis, due to its role in industrial processes such as pollution reduction in the auto industry, and ethanol or other fuel production. In the automotive catalytic converters CO oxidation reduces the poisonous CO to CO2 by reacting with O2. READ MORE

5. 9. Indocyanine-green fluorescence imaging to detect anastomotic insufficiency after esophagectomy

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

   Author : Love Kildetoft; [2024]
   Keywords : Fluorescence; Imaging; Indocyanine-green; ICG; Esophageal cancer; Physics; Photonics; Image Analysis; Blood Perfusion; Anastomotic leakage; Anastomotic insufficiency; Physics and Astronomy;

   Abstract : This research project is concerned with the development of simulation models and image analysis algorithms, as well as instrumentation for characterizing anastomotic leakages after a patient has undergone surgery for esophageal cancer. Anastomotic leakage is a high-incidence complication after esophagectomy, a surgical procedure for esophageal cancer. READ MORE

6. 10. Nested Noun Phrase Detection in English Text with BERT

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

   Author : Shweta Misra; [2023]
   Keywords : Phrase detection; nested noun phrase identification; phrase structure identification; sentence parsing; transformer models; machine learning; natural language processing; Frasdetektering; kapslad substantivfrasidentifiering; frasstrukturidentifiering; meningsanalys; transformers-modeller; maskininlärning; naturlig språkbehandling;

   Abstract : In this project, we address the task of nested noun phrase identification in English sentences, where a phrase is defined as a group of words functioning as one unit in a sentence. Prior research has extensively explored the identification of various phrases for language understanding and text generation tasks. READ MORE
