2. 1. The diagnosis and protection of the auditory peripheral system

   Author : Mao Li Duan; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Cochlea; inner hair cell; outer hair cell; glutamate; post-synaptic receptor; auditory brainstem response; forward masking; noise trauma; hearing loss;

   Abstract : The main focus of this thesis is on the diagnosis and prevention of peripheral hearing loss. An auditory evoked response measure (forward masking) was developed that specifically tests the function of the inner hair cells, independently of the outer hair cells. READ MORE

4. 2. Rapid sintering of ceramics by intense thermal radiation

   Author : Duan Li; Zhijian Shen; Lutz-Michael Berger; Stockholms universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sintering; sintering by intense thermal radiation; spark plasma sintering; heat transfer; mass transfer; scattering; coalescence; densification; grain growth; numerical simulation; porous ceramic; foaming; nanostructure; hierarchical heterogeneities; permeability; Materials Chemistry; materialkemi;

   Abstract : Sintering is an important processing step for obtaining the necessary mechanical stability and rigidity of ceramic bulk materials. Both mass and heat transfer are essential in the sintering process. The importance of radiation heat transfer is significantly enhanced at high temperatures according to the well-known Stefan-Boltzmann’s law. READ MORE
