    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Elisabeth Fenske; [2022-10-27]
    Keywords : ;

    Abstract : Chemicals are present in almost every part of human society and their benefits to our everyday life are undeniable. Besides those benefits, chemicals are known to cause harm to both human health and the environment. READ MORE

  3. 22. Methodologies for training detection dogs and scent sample storing

    University essay from SLU/Dept. of Clinical Sciences

    Author : Rebecka Clern; [2022]
    Keywords : detection dogs; scent training; canine scent detection; search dogs; scent samples;

    Abstract : Dogs’ spectacular sense of smell has been used as a detection tool by humans in many areas. Their olfaction was first used as a hunting tool, but dogs’ detection skills have been shown to also be applicable in, for example, detection of drugs, explosives, and firearms as well as disease detection.

  4. 23. Gas Chromatography Mass Spectrometry Analysis of Epoxides in Gas Phase Reactions

    University essay from KTH/Kemi

    Author : Stephanie Kylington; [2022]
    Keywords : organic peroxy radicals; unsaturated alkenes; TD-GCMS; Tenax® TA; internal standard; organiska peroxidradikaler; omättade alkener; TD-GCMS; Tenax® TA; intern standard;

    Abstract : En nyligen genomförd studie visade att reaktioner mellan vissa radikaler och omättade alkener är snabbare vid rumstemperatur än vad man tidigare har trott. Dessa reaktioner är viktiga för atmosfäriska oxidationscykler och följaktligen var syftet med detta masterprojekt att beräkna hastighetskonstanterna för dessa reaktioner mellan metyljodid och 1-jodidpentan med tetrametyletylen, isopren och limonen vid rumstemperatur genom att kvantifiera respektive epoxid; tetrametyloxiran, isoprenmonoxid och limonen 1,2 epoxid, som producerades.

  5. 24. Identification of photodegradation products from commonenvironmental pollutants using gas chromatography coupled withhigh resolution mass spectrometry

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Vanessa Cajes; [2022]
    Keywords : Photodegradation; Organic contaminants; High resolution mass spectrometry; Identification; Spectral library;

    Abstract : Photodegradation is a major degradation mechanism for many environmental contaminants, both in indoor environments as well as in outdoor environments, and many of the contaminants are persistent and toxic. However, there is a lack of knowledge about the exact degradation process for many of them. READ MORE

  6. 25. Viability, feasibility and Sustainability of emission reducing solutions for Nordic wood stoves: Testing and evaluation : Degree project for Master in mechanical engineering with focus on innovative and sustainable product development

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Casper Berg; [2022]
    Keywords : Catalytic Filters; Variable filter deployment; Wood stove Emissions; Eco Design 2022; Reduced Emissions; Katalytiska filter; Varierande filter; Utsläpp från vedkaminer; Eco Design 2022; Reducerade utsläpp;

    Abstract : As of 2022 the European Union introduced a new Eco Design legislation which states emission limits for stoves sold in the EU. There are already requirements on emissions, but as both legislation are to be harder and there is a higher interest in Eco friendly products, there is an interest to study different ways to reduce the emissions from wood stoves.
