  1. 1. Tuning physical and chemical attributes of the synthetic implant poly(L-lactic acid) and its effects on biological stimulation

    Kandidat-uppsats,

    Författare :Gabriella Sverlinger; Felicia Norman; Nora Othman; Wilma Hämäläinen; Michaela Thyberg; Maja Jonsson; [2023]
    Nyckelord :Polylactic acid; degradation rate of PLLA; physio- chemical properties of PLA; injectable PLLA;

    Sammanfattning : Poly(lactic acid) (PLA) is a polymer chain consisting of repeating units of lactic acid (LA) used in various biomedical applications because of its biocompatible features. It is commonly used as a subdermal filler and constitutes as the main ingredient in SculptraR, which is a collagen regenerating filler used to treat lipoatrophy of the cheeks or to rejuvenate the skin.

  3. 2. Jämförande studie av två verktyg avsedda för ekosystemtjänstanalyser

    Kandidat-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Moa Sjösten Andersson; Sandra Nilsson; [2023]
    Nyckelord :Ekosystemtjänster; ekosystemtjänstanalys; analysverktyg; urbana grönytor;

    Sammanfattning : Det nuvarande stadsplaneringsidealet leder till att många städer blir allt tätare och att urbana grönytor går förlorade i en accelererande takt. Förtätningen bidrar därmed till att livsviktiga ekosystemtjänster utarmas eller elimineras totalt, vilket i sin tur resulterar i ett flertal negativa konsekvenser på samhällelig nivå. LÄS MER

  4. 3. Hypoxia and hematopoietic stem cell control with the substance Adaptaquin : An evaluation of hematopoietic stem cell’s proliferation and differentiation in artificially induced hypoxia

    Kandidat-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Författare :Jens Christiansen; [2023]
    Nyckelord :Adaptaquin; Flow cytometry; Hematopoietic stem cells; Hypoxia; Hypoxia inducible factor; Prolyl hydroxylase; Adaptaquin; Flödescytometri; Hematopoetiska stamceller; Hypoxi; Hypoxi inducerande faktor; Prolylhydroxylas;

    Sammanfattning : Hematopoietic stem cells (HSCs) have historically been difficult to maintain ex vivo with many attempts to culture them in vitro by mimicking their natural biological environment. Providing a hypoxic environment is one way to achieve this goal and can be performed by using hypoxia stimulating compounds that inhibits the degradation of HIF1a which plays an important role in regulating hypoxia.

  5. 4. Assessment Of Plastic Degrading Abilities Of Autotransporter Domains Containing Esterase On Synthetic Polyesters

    Master-uppsats, Lunds universitet/Bioteknik; Lunds universitet/Bioteknik (master)

    Författare :Linus Hansen; [2023]
    Nyckelord :Biotechnology; Enzymes; Plastic degradation; Plastic waste management; Technology and Engineering;

    Sammanfattning : In today's world, plastic pollution has become a widespread problem with plastics in oceans, rivers and forests. The use of plastic has increased rapidly since it first was developed and that is because of its advantageous abilities. LÄS MER

  7. 5. Reduction of Acrylamide in Reject Water from Sludge Dewatering

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Martina Aspegren; [2023]
    Nyckelord :Water treatment techniques; Ozonation; Moving bed biofilm reactor; Trickling filter; Biological degradation; Lake Mälaren; attenreningstekniker; Ozonering; Biofilmreaktor med rörlig bädd; Biobädd; Biologisk nedbrytning; Mälaren;

    Sammanfattning : Norrvatten produces and delivers drinking water to approximately 700 000 people in the northern part of the Stockholm region in Sweden. In their water treatment plant Görvälnverket, water from Lake Mälaren is purified. During the purification, sludge is produced. To be able to use the sludge as landfilling material, it must be dewatered. LÄS MER
