  1. 1. Study of surfactant-preservative and protein-preservative interactions in multi-dose injectable formulation

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

    Author : Javier Lagares Martín; [2023]
    Keywords : Phenol; polysorbate 80; cloud point; somatropin; aggregation; titration; light scattering; salt; surfactant; preservative; protein; tonicity adjusting agents; multi-dose injectable formulation; pharmaceutical technology; Technology and Engineering;

    Abstract : Multidose injectable formulations require a preservative such as phenol to ensure sterility and protection against microbial contamination during clinical use. However, it is known that the interaction between these components and non-ionic surfactants such as polysorbate 80, also found in this type of formulations, present incompatibilities, which can lead to decreases in the efficacy of the product.

  3. 2. Scandinavian Mummies : Interpreting the preservative qualities of Danish Bronze Age Mounds

    University essay from Uppsala universitet/Institutionen för arkeologi och antik historia

    Author : Ellinor Grönkvist; [2023]
    Keywords : Burial mounds; Bronze Age; Denmark; Preservation; Oak-log coffins; Gravhögar; Bronsålder; Danmark; Bevarande; Ekstockskistor;

    Abstract : This paper explores/investigates the circumstances around the unusual level of preservation of organic materials within certain mounds in Jutland, Denmark, as well as the scientific benefits of these findings. These mounds contain coffins made from oak-logs and within them mummies of different degree of preservation have been found. READ MORE

  4. 3. Phenol-Protein Solution Stability

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

In the 2017 proposal by Pembroke, it is to be demolished and replaced with a 14-storey tall glazing building. The protest against this proposal paused the demolition of Passagenhuset. There has been a renowned aggressive preservation culture in Sweden. READ MORE

  6. 5. Remediation of an arsenic-contaminated anoxic aquifer in hjältevad with zerovalent iron : assessment and modelling of sorption strength and solubility of arsenic

    University essay from SLU/Dept. of Soil and Environment

    Author : Kathrin Leicht; [2021]
    Keywords : arsenic remediation; zerovalent iron; anoxic aquifer;

    Abstract : In-situ injection of zerovalent Iron (ZVI) particles to remediate contaminated groundwater is a widely applied approach. However, studies assessing the remediation and immobilisation mechanisms of Arsenic (As) under anoxic field conditions with zerovalent iron particles are lacking, especially for nanosized sulphidated ZVI (S-nZVI) and oxidic shell free ZVI (OSF-nZVI).
