  1. 1. Estimating Risks of Pharmaceutical NSAID Mixtures in Surface Waters through Risk Cups : – Implications for Sustainability

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Per Mandahl; [2020]
    Keywords : Sustainable Development; Ecotoxicology; Risk Cup; Pharmaceuticals; Surface Water; MEC PNEC;

    Abstract : Background: Use of pharmaceuticals can lead to unchanged or metabolite residues in surface water that may result in negative environmental effects. Sweden has adopted the Generational goal defining direction and changes needed to become a sustainable nation, these align with the UN Sustainable Development Goals (SDGs). READ MORE

  2. 2. Possible unexpected peaks from oil drop size measurements in milk

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

    Author : Laura Schalkwijk; Rodrigo Olmedo Sotomayor; [2020]
    Keywords : laser diffraction; oil droplet size; milk; pasteurised milk; unexpected peaks; mastersizer; food engineering; livsmedelsteknik; Technology and Engineering;

    Abstract : The shelf life of milk is amongst others dependent on the size of the oil droplets. These droplets can be measured using the laser diffraction (LD) technique. LD is a popular technique to measure particle size distributions (PSD) that has an outstanding broad measuring range capability, is easy-to-use and has a high reproducibility. READ MORE

  3. 3. Bronze-Steel Friction Characteristics under the Lubrication of Modified Water/Glycerol Mixtures

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Karim Hamouda; [2017]
    Keywords : Glycerol; glycerol additives; stick-slip; shudder; friction modifiers;

    Abstract : Increasing environmental awareness has driven a lot of research to look into various environmentally friendly lubricants which can replace more conventional mineral oil based lubricants. This is true in particular for marine and hydropower applications where the risk of lubricant leakage can be damaging to the local environment. READ MORE

  4. 4. Investigation of mixing time and relative concentration effects in adhesive mixtures for drug inhalation

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Simon Åslund; [2015]
    Keywords : Aerosol Drug Inhalation Adhesive mixtures Next Generation Impactor Laser diffraction; Technology and Engineering;

    Abstract : A common approach to treat respiratory diseases is with adhesive powder mixtures. These are dispersed into an aerosol upon inhalation. It has been found that the performance of such mixtures can be improved by adding fine particle lactose, but exactly why is yet to be established. READ MORE

  5. 5. Ecotoxicological effects on a food-web exposed to pharmaceuticals : Uptake and effects of oxazepam, fexofenadine and a mixture of both in algae, zooplankton and sticklebacks.

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anna Sundelin; [2015]
    Keywords : Bioconcentration; Bioaccumulation; Behaviour; Pharmaceutical mixtures.;

    Abstract : Complex mixtures of biologically active pharmaceutical residues continuously enter aquatic environments via wastewater, where it can affect species through preserved human drug targets or cause unexpected effects in non-target species. Benzodiazepines and antihistamines are two highly consumed groups of pharmaceuticals that have been shown to bioconcentrate in aquatic organisms and induce behavioural alterations affecting individual fitness.
