1. 16. Investigation of Heat Treatment and Quenching Cycles on Microstructure and Mechanical Properties of Hadfield Steel

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

   Author : Cécile Chaxel; [2022]
   Keywords : Hadfield steel; Manganese; Heat treatments; Carbides;

   Abstract : Hadfield steel is a material used in different industrial application, when a good resistance to severe impact loads and abrasion is expected. Its high ductility, high toughness, good work hardening capacity and high fatigue resistance make it especially suitable for theses conditions. READ MORE

3. 17. Determination of bio-accessible amounts of metal trace elements in baby food using In vitro artificial digestion

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Marcus Andersson; [2022]
   Keywords : Food; toxic metals; children; bio-accumulation; artificial digestion; ICP-MS;

   Abstract : Prefabricated baby food is under strict EU legislation by Commission Regulation (EC) 1881/2006 Setting maximum levels for certain contaminants in foodstuffs regarding the maximum allowed content of potentially harmful elements. For potentially toxic trace elements the regulated maximum content is regulated for lead, cadmium, mercury, inorganic tin, inorganic arsenic, cesium, copper and manganese. READ MORE

5. 19. Multivariable analysis for studies of the origin of residual peroxide

   University essay from KTH/Fiber- och polymerteknologi

   Author : Sara Johansson; [2022]
   Keywords : Hydrogen peroxide; Hydrogen peroxide bleaching; PCA; Tepidiphilus; beneficial bacteria; paper mill; Väteperoxid; väteperoxidblekning; PCA; Tepidiphilus; gynnsamma bakterier; pappersbruk;

   Abstract : På pappersmaskin 11 i Hallsta pappersbruk tillverkas högglansigt papper som bleks med väteperoxid. Om väteperoxiden som finns kvar efter blekningen, kallat restperoxid, kommer ut på pappersmaskinen sliter detta på termovalsarna, vilket påverkar slutprodukten. READ MORE

6. 20. Evaluation of long-term effects of excavated sulfide-bearing rock : - A case study in western Sweden

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Ida Sundblom; [2022]
   Keywords : sulfide-bearing rock; acid rock drainage; sulfide oxidation;

   Abstract : Sulfide-bearing rock that is excavated in conjunction with construction projects can cause environmental and construction engineering problems. Sulfidic minerals oxidize when they are exposed to an oxidant and water, which can make them generate acid rock drainage (ARD) with high concentrations of metals and sulphate. READ MORE
