Liksom ett par nya ögon. Frithiof Holmgren och synsinnets problematik

Popular Abstract in Swedish Studien handlar om fysiologen Frithiof Holmgrens försök att fastställa seendets natur på experimentell väg. Avsikten är att problematisera Holmgrens intresse för synsinnet mot bakgrund av de metoder och vetenskapliga ideal som var förhärskande inom den experimentella fysiologin, det ämne som Holmgren introducerade i Sverige 1862. Generellt kan man säga att Holmgrens forThis study deals with research on the visual organ as pursued in experimental physiology during the latter half of the nineteenth-century. In the 1850's och 60's experimental physiology developed as a new, scientific discipline within the curriculum of western medicine. By opposing the natural philosophical and vitalistic viewpoint of romantic medicine and by proclaiming measuring devices, animal

Object characterization with refractometric digital holography

We demonstrate a Digital Holographic method where two different substances in a blend can be discerned. The method requires only one set of exposures and one reconstruction in the plane of focus. The large scale phase variation of the phase image is unwrapped by Flynn’s discontinuity algorithm to reveal which regions in the sample the phase has decreased or increased upon transmission of the illumi

The Crystal Structure of III-V Semiconductor Nanowires: Growth and Characterization

This thesis concerns growth and characterization of gold-particle seeded nanowires of III-V semiconductor materials (III-V NWs). The nanowires were grown using metal-organic vapour phase epitaxy (MOVPE) and characterized by various microscopy techniques. In particular cross-sectional scanning tunnelling microscopy (XSTM) and cathodoluminescence microscopy (CL) were employed to investigate heterost

Romanian grammar: its peculiarities from Indo-European perspectives

This article discusses peculiarities of the Romanian grammar in comparison with other Ind-European languages from historical perspective. It shows that Romanian uniquely preserves older characteristics of Indo-European languages, which makes it look 'an odd-one-out' among other Romance languages.

Polisen i förändring: Intervjuer med de anställda och analys of deras arbetsmiljö

This report is based on 75 in length interviews with employees, both police and civilians, concerning their health, their work environment, leadership and organization. A scale was derived from the interviews and when used together with statistics on turn-over rates and sick leave absences formed a useful tool for police leadership to identify troublesome or potentially troublesome work environmen
