1. 1. Reduction of Acrylamide in Reject Water from Sludge Dewatering

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Martina Aspegren; [2023]
   Keywords : Water treatment techniques; Ozonation; Moving bed biofilm reactor; Trickling filter; Biological degradation; Lake Mälaren; attenreningstekniker; Ozonering; Biofilmreaktor med rörlig bädd; Biobädd; Biologisk nedbrytning; Mälaren;

   Abstract : Norrvatten produces and delivers drinking water to approximately 700 000 people in the northern part of the Stockholm region in Sweden. In their water treatment plant Görvälnverket, water from Lake Mälaren is purified. During the purification, sludge is produced. To be able to use the sludge as landfilling material, it must be dewatered. READ MORE

3. 2. How Substances in Agricultural Waste Material Can Be Used as Active Ingredients in Skin Care Products

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

   Author : Lisa Prawitz; [2020]
   Keywords : Cosmetics; Skin care; Active substances; Agriculture; Skin aging; Pharmaceutical technology; Läkemedelsteknologi; Technology and Engineering;

   Abstract : Aging of the skin is an inevitable process that occurs throughout a lifetime and exposure to environmental pollutants is a factor accelerating this process. Phytochemicals present in plants possess biological activities known to protect or repair the skin cells and when used in skin care products they can slow down the skin aging process. READ MORE

   Abstract : This report summarizes the work on the cloning, expression, and purification of PerR, a metal sensing regulator from Saccharopolyspora erythraea and the subsequent characterization using small angle X-ray scattering and other biochemical methods. The report aims to provide an insight into prokaryotic metal homeostasis, provide a better understanding of how PerR works and provide valuable information for the continued work on the crystallization of PerR.

5. 4. Kopparassocierad kronisk hepatit hos hund

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

   Author : Sofie Djerf; [2019]
   Keywords : kopparassocierad; kronisk hepatit; cirrhos; koppar; ackumulation; koppartoxikos; hund; etiologier;

   Abstract : Kronisk hepatit är relativt vanligt förekommande hos hund och kan orsakas av många olika etiologier, varav en är förhöjd upplagring av koppar i levern. Koppar är ett essentiellt spårämne som intas med födan. Fysiologiskt sker den främsta kopparupplagringen i levern och kopparöverskott utsöndras främst från kroppen via gallan. READ MORE

6. 5. Pankreatit hos hund och katt : – etiologiska och patologiska skillnader

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

   Author : Siri Johansson; [2018]
   Keywords : pankreatit; katt; hund; etiologi; patologi;

   Abstract : Pankreatit anses vara ett vanligt sjukdomstillstånd hos både hund och katt och karakteriseras av inflammation i bukspottskörteln. Denna litteratursammanställning ämnar utröna patogenesen för pankreatit samt dess patologiska och etiologiska skillnader hos hund respektive katt. READ MORE
