2. 1. The influence of fracture on activity, social participation and quality of life among older adults. Results from the population study Good Ageing in Skåne

   Author : Henrik Ekström; Geriatrik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : The aims of this thesis where the target population has been older adults suffering from osteoporosis related fractures were firstly to study the association between functional impairment due to pain, and activity expressed as walking speed (WS) and Timed Get up and-Go (TUG), and to examine the associations between functional impairment and social participation (SP) and quality of life (QoL). Secondly, to study the association between activity and SP and QoL. READ MORE

4. 2. Evaluating Cathode Catalysts in the Polymer Electrolyte Fuel Cell

   Author : Henrik Ekström; Göran Lindbergh; Anders Lundblad; Anthony Kucernak; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; fuel cell; humidity; model electrodes; Nafion; oxygen reduction; PEMFC; platinum; polymer electrolyte; thin film evaporation; titanium oxide; bränslecell; fuktighet; modellelektroder; Nafion; PEMFC; platina; polymerelektrolyt; syrereduktion; tunnfilmsförångning; titanoxid; Electrochemistry; Elektrokemi;

   Abstract : The polymer electrolyte membrane fuel cell (PEMFC) converts the chemical energy of hydrogen and oxygen (air) into usable electrical energy. At the cathode (the positive electrode), a considerable amount of platinum is generally required to catalyse the sluggish oxygen reduction reaction (ORR). READ MORE

   Abstract : To facilitate the shift from fossil to renewable energy sources, energy storage is needed to cope with the intermittent nature of technologies such as solar, wind, and wave power. One storage alternative is battery-based stationary energy storage. READ MORE

7. 5. 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
