2. 21. Identification and Community Management of Severe Acute Malnutrition : Empirical evidence in rural Southern Ethiopia

   Author : Amare Worku Tadesse; Eva-Charlotte Ekström; Yemane Berhane; Henrik Friis; Uppsala universitet; []
   Keywords : Severe acute malnutrition; children; anthropometric indicators; integrated outpatient therapeutic programme; recovery; Ethiopia; Nutrition; Nutrition;

   Abstract : The current recommended standard management for all children with severe acute malnutrition (SAM) is Community-based Management of Acute Malnutrition (CMAM). CMAM has a community-based outpatient therapeutic program (OTP) to treat uncomplicated SAM and has been scaled-up and integrated with government health services in low-resource settings. READ MORE

4. 22. Radiocesium in the forest and forest industry, Studies on the flow, occurrence and technological enhancement of radionuclides in the forest industry with emphasis on radiocesium

   Author : Aaro Ravila; Lund Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; forestry technology; forestry; recovery; Recycling; enhancement; fallout; radiocesium; wood; ash; biofuel; Silviculture; radiation.; Skogsvetenskap; skogsbruk; skogsteknik;

   Abstract : In the aftermath of the nuclear weapons testing and as compared with agriculture, the forest industry has received relatively little attention in spite of its large-scale use of radiocesium- contaminated wood and water. After the Chernobyl nuclear power plant accident in 1986, numerous studies of the forest environment have been conducted with respect to radionuclide transfer through the forest ecosystem or its many components.

5. 23. Designing out waste - Exploring barriers for material recirculation

   Author : Isabel Ordonez Pizarro; Chalmers tekniska högskola; []
   Keywords : HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste sorting; sustainable development; Water; Waste; Urban; waste management; Resources; resource recovery; ​Recycling; designing with waste; recycling;

   Abstract : This doctoral thesis has investigated what hinders material recirculation in society, to later suggest possible ways to support material recirculation in the future. Since material recirculation is proposed as a way to use waste materials for new production, it was deemed relevant to investigate two separate case studies that enabled recirculation from production systems and waste management.

6. 24. Volatile Fatty Acids as a Key to Sustainability and Circularity in Polyhydroxyalkanoates Production

   Author : Hoang Danh Vu; Dan Åkesson; Pau-Loke Show; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioplastics; food waste; polyhydroxyalkanoates; volatile fatty acids; immersed membrane bioreactor; acidogenic fermentation; Resource Recovery; Resursåtervinning;

   Abstract : The negative consequences of plastic pollution on both environmental and socio-economic aspects have motivated the development of sustainable and renewable materials to replace the petroleum-based plastic. Polyhydroxyalkanoates (PHAs), which are bioplastics, having an outstanding biodegradability and rather comparable thermal and mechanical properties, are potential alternatives for the replacement of conventional plastics.

7. 25. Methane and Volatile Fatty Acids Production from Toxic Substrate

   Author : - Lukitawesa; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; toxic substrate; methane; volatile fatty acid; anaerobic digestion; membrane bioreactor; factor; tubular membrane; two-stage digestion; Resource Recovery; Resursåtervinning;

   Abstract : Challenges caused by climate change and global warming have created a demand for improvements in resource recovery and the promotion of a circular economy. Waste management is one such challenge for which more recycling options are required for producing materials and energy sources from wastes. READ MORE
