1. 1. Physical contact in physical education : New perspectives and future directions

   Författare :Annica Caldeborg; Marie Öhman; Joacim Andersson; Ninitha Maivorsdotter; Jesper Andreasson; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physical contact; physical education; PE; touch; student perspective; heteronormativity; gender; immigrant students; scoping review;

   Sammanfattning : This thesis takes its point of departure in the research field of intergenerational touch in educational settings. Specifically, it is mainly the student perspective of physical contact between teachers and students in physical education (PE) that is of interest. In addition, a scoping review has also been conducted. LÄS MER

3. 2. The Physical Foundation of the Patterning of Physical Action Verbs : A Study of Chinese Verbs

   Sammanfattning : This work is a study of verbal semantics with a focus on the discussion and illustration of the role of body parts and the semantic incorporation into verbal roots of the actions that involve various body parts. Following a general discussion of the basic issues of language construction and human body actions with the image schemas of force-dynamics presented in line with the framework of cognitive semantics, it is argued that the event structures of physical action verbs are not arbitrarily constructed but rather the constructions are built through systematic cognitive processes in relation to both human physical reality and concrete reality in the world.

5. 4. Dynamic Wetting of Solid Surfaces, Influence of Surface Structures and Surface Active Polymers

   Författare :Stina Gerdes; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; stick-slip; Wilhelmy plate; block copolymers; surface active polymers; surface channels; spreading; contact angles; dynamic wetting; surface structures; Fysikalisk kemi;

   Sammanfattning : The effect of surface structures on the dynamics of wetting was investigated through measurements of the dynamic contact angle and spreading velocity of oil droplets spreading over surfaces with parallel and gridlike V-shaped channels. A rim of liquid was observed to spread out in the channels ahead of the dropfront after a short time of spreading (seconds). LÄS MER

7. 5. Metal Particles – Hazard or Risk? Elaboration and Implementation of a Research Strategy from a Surface and Corrosion Perspective

   Sammanfattning : Do metal particles (including particles of pure metals, alloys, metal oxides and compounds) pose a hazard or risk to human health? In the light of this question, this thesis summarizes results from research conducted on metal particles, and describes the elaboration and implementation of an in vitro test methodology to study metal release from particles through corrosion and dissolution processes in synthetic biological media relevant for human exposure through inhalation/ingestion and dermal contact. Bioaccessible metals are defined as the pool of released metals from particles that potentially could be made available for absorption by humans or other organisms. LÄS MER
