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

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

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

    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.

  3. 2. Monitoring marine alien and invasive species. A comparison between the traditional method (eRAS) and DNA-based identification of species.

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Josefin Holm; [2023-08-22]
    Nyckelord :;

    Sammanfattning : There is a major concern with the uncontrolled spreading of alien and invasive species, caused by an increase in travelling by boat globally. These are dispersed via ballast water, by fouling on ships and in fishing gear. LÄS MER

  4. 3. Jämförelse av torr bearbetning och minimalsmörjningseffekter på fräsning av austenitiskt rostfritt stål

    M1-uppsats, Högskolan i Gävle/Maskinteknik

    Författare :Adam Norell; Darav Hajo; [2023]
    Nyckelord :MQL; milling; stainless steel; tool wear; MQL; fräsning; rostfritt stål; verktygsförslitning;

    Sammanfattning : Fräsning och annan intermittent skärande bearbetning ger upphov till termisk utmattning av skärverktyg. Problemet med termiska sprickor blir större vid bearbetning av värmehållfasta material som austenitiskt rostfritt stål eftersom värmeväxlingarna i skärverktyget blir mer extrema. LÄS MER

  5. 4. Assessment and evaluation of heterogeneity in data from immune infiltration spatial niches in lung cancer

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Mahta Keivani Najafabadi; [2023]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : The protein biomarker expressions in three types of sampled immune INFILTration spatial niches in lung cancer tissue were measured using the new technology Digital Spatial Profiler (DSP). The three types of immune INFILTration that were observed in lung tumors were STROMA identified as immune cells separate from tumor cells, Tertiary lymphoid structures (TLS) identified as dense structures of organized immune cells and finally Infiltraterate where immune cells dispersed among and in direct contact with tumor cells (INFILT).

  7. 5. Fastläggning av arsenik med nollvärt järn i mikrostorlek : Uppföljning av ett pilotskaleförsök

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Frida Aronsson; [2023]
    Nyckelord :contaminated soil; arsenic; zero-value iron; mZVI; pilot test; pilot study; förorenad mark; arsenik; nollvärt järn; mZVI; pilotförsök; pilotstudie;

    Sammanfattning : Land contaminated with arsenic is a major problem as arsenic is toxic and poses a major health risk to both humans and animals. There are several remediation methods, both in-situ and ex-situ, to prevent and deal with pollution problems in different ways. LÄS MER
