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

    University dissertation from Linguistics and Phonetics

    Author : Hong Gao; [2001]
    Keywords : HUMANIORA; HUMANITIES; Languages and literatures of South and South-East Asia; verbal semantics; trajector; semantic representation; pyscholingistics; polysemy; physical reality; physical foundation; physical action verbs; observability; motion; lexicalization patterning; landmark; intentionality; innateness; physical contact; force-dynamics; combinability; conflation; cognitive semantics; active zone; affectability; Chinese; Kinesiska och språk och litteratur från Syd- och Sydostasien; Linguistics; Lingvistik; Grammar; semantics; semiotics; syntax; Grammatik; semantik; semiotik;

    Abstract : 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.

    Abstract : 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.

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

    University dissertation from Institute for Surface Chemistry, Box 5607, SE-114 86 Stockholm

    Author : Stina Gerdes; [1998]
    Keywords : 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;

    Abstract : 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). READ MORE

  5. 5. Insulator charging by contact with metals

    University dissertation from Institute for Surface Chemistry, Box 5607, SE-114 86 Stockholm

    Author : Frank Nordhage; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In spite of the fact that charge transfer is one of the oldest physical phenomena known, the basic mechanisms involved are not yet quite understood. For experimental investigations of the charge transfer to insulators it is still informative to scrutinize electrification systems consisting of as simple components as possible. READ MORE
