1. 16. Physical Modeling of Brain and Head Kinematics

   Författare :Johan Ivarsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brain injury; skull base; rotational acceleration; physical models; lateral ventricles; head kinematics; padding materials; sulci; free motion headform; brain kinematics;

   Sammanfattning : The development of head injury criteria and countermeasures for head protection requires understanding of how different factors affect brain and head kinematics. In this thesis, 2D physical models of the human head were developed and used to evaluate how various factors affect brain kinematics during angular head kinematics. LÄS MER

3. 17. Living Structure for Understanding Human Activity Patterns Using Multi-Source Geospatial Big Data

   Författare :Zheng Ren; Bin Jiang; Stefan Seipel; Itzhak Benenson; Högskolan i Gävle; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; living structure; topological representation; human activities; natural cities; urban centres; complex network; head tail breaks; big data; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : Geographic space is not neutral or lifeless, but an intricate living structure composed of numerous small features and a few large ones across all scales. The living structure is crucial for comprehending how geographic space shapes human activities. LÄS MER

5. 19. Evaluation of thermal comfort of head gear : a method to measure heat transfer characteristics

   Författare :Xiaoxiong Liu; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

   Sammanfattning : This study was carried out within the research project "Thermal properties of protective helmets - improvement, validation and standardization of a measurement method" which was a continuation of a research project being carried out since 1992 at the Division of Industrial Ergonomics, Department of Human Work Sciences, Luleå University of Technology, Sweden, with co-operation of the Department of Ergonomics, National Institute for Working, Life (NIWL), Solna, Sweden. A method was developed for measuring the evaporative heat transfer properties of helmets, based on the results of a thorough literature survey. LÄS MER

7. 20. Controlling Fusarium Head Blight in oat

   Författare :Alfia Khairullina; Tillämpad biokemi; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; FHB; oat; UDP-glucosyltransferase; deoxynivalenol; mycotoxins; biocontrol; Clonostachys rosea; Fusarium head blight; Fusarium graminearum; endophytes;

   Sammanfattning : Oats (Avena sativa) is a versatile crop grown worldwide for animal feed and human consumption. Humanoat consumption has recently risen due to its various health benefits. However, oats are susceptible toFusarium head blight (FHB) caused by various Fusarium fungi. FHB reduces yield and leads to mycotoxinaccumulation. LÄS MER
