  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. Comparison of in-situ bioremediation of soil contaminated with chlorinated hydrocarbons

    Magister-uppsats, Högskolan i Halmstad

    Författare :Tianyu Qin; [2020]
    Nyckelord :bioremediation; biostimulation; bioaugmentation; product; chlorinated hydrocarbon;

    Sammanfattning : In recent years, due to the continuous development of machinery, electronics, leather, chemical companies and dry-cleaning industry, more and more chlorinated hydrocarbons accumulate in the soil, causing serious harm to the environment. The accumulation of chlorinated hydrocarbons and the teratogenic, carcinogenic, and mutagenic hazards seriously threaten human health. LÄS MER

  4. 3. Påverkan på mikroorganismer i grundvatten, Biostimulering med syreavgivande medel

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Martina Strömberg; [2018]
    Nyckelord :biostimulation; oxygen release compound; ORC; ORM; in situ; toluene; Earth and Environmental Sciences;

    Sammanfattning : It is common that oxygen is a limited factor in microbial decomposition of a substance. Biostimulation with oxygen release compound, increase dissolved oxygen in groundwater and stimulate natural decomposition of petroleum hydrocarbon. LÄS MER

  5. 4. Techno-Economic Feasibility Study for the Production of Microalgae Based Plant Biostimulant

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Laurent Arnau; [2016]
    Nyckelord :Biomass; sustainability; photobioreactor; flocculation; centrifugation; sterilization;

    Sammanfattning : Microalgae are considered as a potential feedstock for many promising applications. Some active substances in microalgae have plant biostimulation effects potentially useful in agriculture. However, to produce such a microalgal biomass, specific microalgae cultivation and post-treatment processes must be designed to preserve active substances. LÄS MER

  7. 5. In situ-metoder för sanering av klorerade lösningsmedel : utvärdering med avseende på svenska förhållanden

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Elin Abrahamsson; [2015]
    Nyckelord :Grundvatten; In situ-sanering; Klorerade lösningsmedel; Mark.;

    Sammanfattning : I nuläget finns det 428 områden registrerade som förorenade med klorerade lösningsmedel iSverige. Dessa ämnen har använts inom svensk industri som avfettnings- och lösningsmedelsedan 1930-talet. LÄS MER
