1. 1. Effects of pharmaceutical excipients on the chemical stability of therapeutic proteins in a parenteral formulation

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

   Författare :Emmanuel Gulangayan Deniola; [2022]
   Nyckelord :Chemical stability; protein degradation; GA-Z; somatropin; pharmaceutical excipients; liquid chromatography; pharmaceutical technology; Chemistry;

   Sammanfattning : Proteins and peptides are widely used for the prevention, management, and cure of various illnesses. This vast therapeutic potential represents a significant portion of the pharmaceutical industry in the form of vaccines, antibodies, enzymes, and other protein-based therapeutics. LÄS MER

3. 2. Design and Optimisation of an Aquifer Storage and Recovery System - Options for long term storage under natural hydraulic gradients

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi

   Författare :Simon Kreipl; [2021]
   Nyckelord :Aquifer storage and recovery; well-field design; groundwater modelling; numerical modelling; FEFLOW; Technology and Engineering;

   Sammanfattning : Aquifer storage and recovery (ASR) is a concept where water is stored in an aquifer during times when it is available, thus creating artificial groundwater, which can later be recovered by pumping when it is needed (Pyne, 1995). One ASR cycle consists of a injection, a standby and a recovery phase. LÄS MER

4. 3. Development of a Liquid Chromatography Method to Separate and Fractionate EPA’s 16 Priority Polycyclic Aromatic Hydrocarbons (PAHs)

   Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

   Författare :Tim Sinioja; [2016]
   Nyckelord :;

   Sammanfattning : Polycyclic Aromatic Hydrocarbons (PAHs) are persistent, toxic and carcinogenic environmental pollutants consisting of two or more aromatic rings. The estimation of the toxicity of PAHs can be challenging and time-consuming due to the complexity of PAH-mixtures found in the environment, for example at contaminated sites. LÄS MER

5. 4. Parametric study of density down-ramp injection in laser wakefield acceleration

   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Henrik Ekerfelt; [2015]
   Nyckelord :Laser wakefield acceleration; LWFA; gradient injection; density down-ramp injection; particle-in-cell simulation; PIC; top-view; top view; Thomson scattered light; trace; Physics and Astronomy;

   Sammanfattning : In laser wakefield acceleration (LWFA) a high intensity laser pulse is used to excite a plasma density wave with an associated electric field. This electric field can be used to accelerate electrons. However, to be accelerated the electrons first of all need to enter the plasma wave. This process is called injection. LÄS MER

7. 5. Determination of testosterone esters in serum by liquid chromatography – tandem mass spectrometry (LC-MS-MS)

   Kandidat-uppsats, Organisk Analytisk Kemi

   Författare :Erica Törnvall; [2010]
   Nyckelord :LC-MS-MS; MRM; testosterone; testosterone esters;

   Sammanfattning : Anabolic androgenic steroids are testosterone and its derivates. Testosterone is the most important naturally existing sex hormone for men and is used for its anabolic effects providing increased muscle mass. Testosterone is taken orally or by intramuscular injection in its ester form and are available illegally in different forms of esters. LÄS MER
