1. 21. On the interactions of ions and odor molecules with nanomaterials in water and synthetic urine

   Författare :Isabelle Simonsson; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanomaterials; Surface chemistry; Ion specific effects; MOF synthesis; Odor control; Adsorption; Synthetic urine;

   Sammanfattning : Towards the quest of finding materials to be used as adsorbents in real systems, it is crucial to understand the underlying adsorption processesfully. In many applications, adsorption occurs in biological fluids containing a vast range of ions, organic molecules, and biomolecules. LÄS MER

3. 22. Alkaline Urine Dehydration : how to dry source-separated human urine and recover nutrients?

   Författare :Prithvi Simha; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Human urine is a renewable resource from which water, nutrients and energy can be recovered and safely recycled. This thesis presents a novel on-site technology, called alkaline dehydration, for recovering nutrients from source-separated urine. LÄS MER

4. 23. Bladder cancer. Urine tumour markers and hematuria

   Författare :Hans Boman; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bladder neoplasm; bladder cancer; tumour markers in urine; hematuria; NMP 22; BTA stat; UBC; TPS; cytology;

   Sammanfattning : Cancer of the urinary organs is one of the more common cancer forms in Sweden, with bladder cancer as the fourth most common cancer among men, and the seventh most common among women. The bladder cancer incidence is rising with age and is seldom seen before 50 years of age. LÄS MER

5. 24. Safe Nutrient Recovery from Human Urine - System and Hygiene Evaluation of Alkaline Urine Dehydration

   Författare :Jenna Senecal-Smith; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Only 7% of the world’s wastewater receives tertiary treatment, while the rest is causing eutrophication, hypoxia and climate change through the plant nutrients found in excreta, particularly urine. If managed adequately, urine can be used as a fertiliser because it contains the same nutrients as the fertilisers used to produce food world-wide. LÄS MER

7. 25. Treatment technologies for human faeces and urine

   Författare :Charles Niwagaba; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis examines simple, cheap, environmentally friendly and resource efficient technologies for the treatment of source-separated human faeces and urine to enable safe recycling of their plant nutrients for plant production in developing countries. Composting of faeces-to-food waste (F:FW) in wet weight mix ratios of 1:0, 3:1 and 1:1 was studied in 78 L reactors insulated by 25 mm styrofoam; and of F:FW in wet volume/weight ratios of 1:0, 1:1 and 1:3 in 216 L reactors insulated by 75 mm styrofoam.
