“They Stopped the Lives of Others”: Stateless Palestinians Facing Bureaucratic Violence in Sweden

Official calls for “failed” asylum seekers to leave Sweden ignore the difficulties and harms befalling stateless people who cannot return to previous countries of residence because they lack citizenship. Stateless people are caught in limbo, a position where they have no prospects of return or of attaining a residence permit in a predictable future. To learn the underlying logics and consequences

Influence of the Workpiece Material Properties on the Cutting Forces

This study focuses on modelling the cutting resistance as a function of the workpiece material properties. Thus, for a workpiece material the cutting resistance may be predicted from the material properties without using any experiments. The cutting resistance may then be used to determine the cutting forces, data which in turn may be used to determine appropriate process parameters and select cut

Machinability of Ductile Single-Phase Materials Used in Accelerator Components - A Study with Focus on Surface Integrity

The focus of this article has been to analyse the machinability, with focus on surface integrity, of oxygen-free copper (OFC) and niobium during turning operations. The results from machining OFC proved that all of the tools that was tested can be used to achieve a surface roughness below Ra = 0.8 µm with the correct cutting data. From the results when machining niobium it showed that only the cem

A Basic Economic Model for Judging Production Development

The described technical-economic model clarifies the influence of different production technological factors on the processing cost of a part. The model represents the fundamental theory for the judging of different types of production development. Various influential factors can be weighted against each other, which leads to different production development scenarios and their effects on the proc

Fyra för landet nya skalbaggar funna i Häckeberga, Skåne

Four species of Coleoptera, not previously reported from Sweden are presented; Euconnus campestris (Schaufuss, 1866) (Staphylinidae: Scydmaeninae), Scopaeus ryei Wollaston, 1872 (Staphylinidae: Paederinae), Acritus homoeopaticus Wollaston, 1857 (Histeridae) and Ephistemus reitteri Casey, 1900 (Cryptophagidae). They have all been collected using car net in an area next to the lake Häckeberga in Sca
