3D Hydrodynamical Modelling of the Solar Chromosphere

We report on 3D radiation-hydrodynamics modelling of the non-magneticsolar atmosphere with emphasis on the problem of the acoustic heating ofthe chromosphere. Our models include the generation of acoustic waves inthe uppermost layers of the solar convection zone their propagationthrough the photospheric layers and their ultimate transformation intoshock fronts which are dissipated in the chromosph

Secretory activity in isolated rat stomach ECL cells

Popular Abstract in Swedish ECL celler är endokrina (peptid-hormon-producerande) celler belägna i magsäckens syra-producerande del (fundus). Cellerna är av stor betydelse vid regleringen av magens saltsyra produktion och sekretion eftersom de innehåller histamin. Frisatt histamin aktiverar intilliggande parietal celler att utsöndra saltsyra. ECL cellen innehåller också polypeptiden chromogranin A ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They are important regulators of gastric acid secretion in the stomach by virtue of their histamine synthesizing and secreting capacity. Histamine in turn stimulates parietal cells to secrete acid. The ECL cell also contains the endocrine polypeptide chromogranin A (CGA) and CGA-derived peptides such as panc

Optical Analysis of biological media - continuous wave diffuse spectroscopy

The main topic of this thesis is real-time quantification of relevant chromophores and light scattering elements in biological media. The presented methods and instrumentation are based on continuous wave (steady-state) optical measurements of (a) spatially-resolved diffuse reflectance from bulk media and (b) combined spatially-resolved and goniometric measurements of re-emitted light from thin sa

How Effects from Teacher-training of Academic Teachers Propagate into the Meso Level and Beyond

This text describes, from a cultural perspective, the role of higher education teacher training, in the systemic development of teaching and learning in higher education institutions. Three main organisational levels are identified: micro, meso and macro; and implications for and of teacher training on each level is discussed. Even though the emphasis is on the meso level, suggestions are made for

The parents school? Narrative research about parental involvement

Popular Abstract in Swedish Föräldrars involvering i skolan har under de senaste decennierna betonats allt mer i skoldebatten. Länge betraktades skolutbildning som enbart ett samhälleligt ansvar, vilket ofta medförde ett markerat avståndstagande från familjen och föräldrarna. Likt andra samhälleliga servicefunktioner har emellertid också skolan i sitt förhållande till sina användare undergått en fOver the last two decades, educational reforms have stimulated an enormous growth in innovative school thinking, effecting both independent schools and mainstream education. Parents and interest groups, previously excluded from general pedagogic practice and planning, are now faced with new opportunities and responsibilities. Parents “invest” in these newly won options in very different ways. Fail

Molecular Exchange in Colloidal Dispersions

This thesis is a study of molecular exchange between the aggregates in a colloidal dispersion. The problem of oil molecular transport at resolubilization of big oil drops by smaller microemulsion droplets is considered as an experimental model system. The resolubilization kinetics was measured through a temperature jump into a droplet microemulsion phase from a two-phase region of microemulsion dr

Management of Sustainability in Construction Works

The present global environmental condition is a consequence of the increasing consumption of natural resources whose depletion exceeds what is physically possible to sustain in the long term. The construction sector is a considerable contributor to this resource depletion and sustainability is adopted in the form of the theory of ecological modernization. The implementation depends to varying exte
