Honing action competence in sustainable development: what happens in classrooms matters.

In effectiveness literature, voices are rising to embrace learning contents beyond mathematics, science, and language. Meanwhile, international policy documents such as the United Nations 2019 Climate Action Summit Report point at the importance of action for sustainable development for establishing acceptable life conditions for current and future generations. Therefore, a candidate learning outcome for broadening effectiveness research's scope is action competence in sustainable development (ACiSD), which consists of the relevant knowledge, willingness, capacity expectations, and outcome expectancy regarding actions for sustainable development.

Detection of tympanic membrane movement using film patch with integrated strain gauge, assessed by optical coherence tomography: experimental study.

Objective: We report an ex vivo and in vivo experimental study of a device designed to measure tympanic membrane movement under normal and pathological conditions, assessed using optical coherence tomography.

Materials And Methods: We designed two types of flexible, round film patch with integrated strain gauge, to be attached to the tympanic membrane in order to measure tympanic membrane movement. Tympanic membrane attachment was assessed using optical coherence tomography.

[Tensometry - development of a measurement technique of the tube function in a temporal bone model].

Objective: Middle ear pressure depends widely on the function of the eustachian tube. Tube dysfunction is often a trigger for middle ear diseases like chronic otitis media but also for barotrauma. Patients with impaired tubal function should not be exposed to situations with extreme pressure changes.

New arguments to explain the high infection rate in posttraumatic spleenless patients.

To get more information about the high infection rate in splenectomized adult patients 211 spleenless patients were investigated with regard to clinical and laboratory data and compared to healthy blood donors. The results show that the infection rate is markedly increased to 30%. Splenectomized patients have decreased IgG levels which is due to diminished IgG1 and IgG4.

The influence of age and particle number on absorption of polystyrene particles from the rat gut.

The bioavailability of polystyrene particles (1 microns) labelled with FITC (3M Company, Düsseldorf) was tested in rats after enteral administration. Since macromolecules and particles are preferentially transported in the lymph, the number of particles was counted in the lymph of the thoracic duct over a 6 h period. Uptake in young rats (6-8 wk) was compared with that in 5 and 9 mo animals.
