1. 1. Impact of calcination temperature and time on quicklime slaking reactivity

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Erik Björnwall; [2021]
   Keywords : Lime slaking reactivity; limestone calcination; Calcium carbonate; SEM;

   Abstract : In this master thesis work calcination parameters' impact on the resulting quicklimes slaking reactivity is investigated. This is done by calcination of three different sedimentary limestones in an N2 atmosphere according to a design of experiment matrix. The limestones are from Wolica Poland, Slite Sweden and Jutjärn Sweden. READ MORE

3. 2. Kalciumomsättning och kalciumreglering : en jämförelse mellan värphöns och mjölkkor

   University essay from SLU/Dept. of Animal Nutrition and Management

   Author : Kajsa Lätt; [2017]
   Keywords : Kalciumbrist; Kalcium; Medullärben; Kalvningsförlamning;

   Abstract : Kalciumbrist är ett kostsamt tillstånd för produktionen. När värphöns drabbas av kalcium-brist försämras skalkvaliteten på äggen och tillslut avtar äggproduktionen. Mjölkkor drabbas oftast av akut kalciumbrist före eller efter kalvning, vilket ofta leder till höga veterinärkost-nader och kan även orsaka andra sjukdomar. READ MORE
