  2. 2. Anthelmintisk effekt av örtblandningen Equus Mundi på cyathostominer

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Isabella Karlsson; [2019]
    Keywords : häst; Equus Mundi; anthelmintika; avmaskning; örter; medicinalväxter; resistens;

    Abstract : Den vanligaste inälvsparasiten hos häst är små blodmaskar. De senaste 10–15 åren har en världsutbredd ökning av resistens mot dagens avmaskningsmedel bevittnats hos hästens små blodmaskar, vilket innebär att färre avmaskningspreparat finns att tillgå och andra metoder krävs för att få bukt med parasitproblemen.

  3. 3. Perfluorooctane sulfonate (PFOS) and related chemicals in eggs from Sweden and China

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Yasmin Karimi; [2019]
    Keywords : PFOS; PFOA; Chicken Egg; LC-MS MS; Organic egg; Conventional egg;

    Abstract : Dietary intake is one of the major routes of human exposure to perfluoroalkyl and/or polyfluoroalkyl substances (PFAS). The objective of this study was to measure perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and perfluorohexane sulfonic acid (PFHxS) in organic and conventional egg from Sweden (n=8, consisted of 4 pooled eggs and 4 individuals) and China (n=9, consisted of 4 pooled eggs and 5 individuals) and compare the concentrations of PFAS between the two categories (organic and conventional).

  4. 4. Trace level analyses of selected perfluoroalkyl substancesin food: Method development and validation

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Mohammad Sadia; [2019]
    Keywords : ;

    Abstract : To comprise the future requirements to detect low levels of perfluoroalkane acids, includingbranched and linear perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA),and perfluorohexane sulfonic acid (PFHxS) in food items, here analytical methods fordetermination of PFOS, PFOA and PFHxS in six different food matrices (cow milk, butter,chicken egg, chicken meat, beef, and fish) were optimized and validated. The optimizedmethod was based on alkaline digestion and solid-liquid extraction using acetonitrile,followed by solid phase extraction (SPE) using a weak anion exchange cartridge as clean-up.

  5. 5. Critical thermal minimum of the embryonic development in the common frog (Rana temporaria)

    University essay from SLU/Dept. of Ecology

    Author : Pontus Eriksson; [2019]
    Keywords : development; Rana temporaria; Anura; critical thermal minimum; embryonic; temperature; degree-days; day; degrees; Oophila; common frog; Ranidae; amphibian; algae;

    Abstract : The embryonic development of anurans is known to be temperature-dependent and well-studied. Oviposition of Rana temporaria (common frog) in the northern temperate climate zone occurs as soon as the ice melts on water bodies. This early oviposition can take place in waters below 5 °C.
