Auger Spectra of K+ L23 Excitations in Potassium Halides

The L23M23M23 Auger spectra of K+ L23 excitation in potassium halides are measured using photon excitation with different energies in the region of the K+ L23 absorption edge (around 300 eV). It is shown that the screening of the two 3p holes caused by the collapsed 3d electron of the K+ L23 exciton leads to a considerable shift (by about (6÷7) eV) of the K+ L23M23M23 Auger bands to higher energie

Superheavy-element spectroscopy: Correlations along element 115 decay chains

Following a brief summary of the region of the heaviest atomic nuclei yet created in the laboratory, data on more than hundred α-decay chains associated with the production of element 115 are combined to investigate time and energy correlations along the observed decay chains. Several of these are analysed using a new method for statistical assessments of lifetimes in sets of decay chains.

Outside the Law : An Ethnographic Study of Street Vendors in Bogotá

Miljontals människor världen över arbetar som gatuförsäljare, utom räckhåll för lagen. Eftersom verksamheten ses som illegal lever försäljarna under ett ständigt hot om att avhysas och att få sina varor konfiskerad. Olika strategier för formalisering, det vill säga stegvis legalisering, förespråkas och tillämpas, av såväl internationella utvecklingsorganisationer som regeringar, för att stärka gatMillions of people worldwide work outside the law as street vendors in order to earn a living. However, they often work in fear of police evictions and confiscations since their work is in many places considered illegal. In this context, formalization (steps towards legalization) is often portrayed as a model for empowerment that allows poor street vendors to improve their well-being. Formalizatio

Human Sciences and Human Interests : Integrating the Social, Economic, and Evolutionary Sciences

Within the disciplines of social, economic, and evolutionary science, a proud ignorance can often be found of the other areas’ approaches. This text provides a novel intellectual basis for breaking this trend. Certainly, Human Sciences and Human Interests aspires to open a broad debate about what scholars in the different human sciences assume, imply or explicitly claim with regard to human intere

Room of silence : an explorative investigation of design students’ redesign of an arena for reflection and existential meaning-making

This paper explores design students’ proposals for a redesign of the interior of a room of silence at the SUS hospital in Malmö. Reflection and existential meaning-making are discussed in relation to the material culture of design, and more specifically in relation to four different themes found among the students’ proposals: nature as common symbolic framework and salutary force; lighting creatin

Doing business for a “higher loyalty”? : How Swedish transnational corporations neutralise allegations of crime

In recent years, two Swedish companies have been a focus of substantial media attention: TeliaSonera and Lundin Petroleum. The defensive strategies employed by these two businesses to deal with allegations of crime will be analysed on the basis of Stanley Cohen’s theoretical work on processes of denial and neutralisation techniques. This paper will focus on a particular form of denial, namely the In recent years, two Swedish companies have been a focus of substantial media attention: TeliaSonera and Lundin Petroleum.

Insights on the structural perturbations in human MTHFR Ala222Val mutant by protein modeling and molecular dynamics

Methylenetetrahydrofolate reductase (MTHFR) protein catalyzes the only biochemical reaction which produces methyltetrahydrofolate, the active form of folic acid essential for several molecular functions. The Ala222Val polymorphism of human MTHFR encodes a thermolabile protein associated with increased risk of neural tube defects and cardiovascular disease. Experimental studies have shown that the

Mapping the Geography of R&D : What Can We Learn for Regional Innovation Policy in the Czech Republic and Beyond?

Abstract: Administrative regions do not necessarily correspond to areas that are homogenous in terms of innovation intensity. Although this has been recognized in the literature, quantitative evidence that explicitly considers this problem is rare. Using spatial exploratory analysis on detailed regional data derived from a census of R&D performers in the Czech Republic, we identify local spati

Mothers and daughters : Heterogeneity of germandirect investments in the Czech Republic

Much has been written on the distinction between vertical and horizontal foreign direct investment. However, most of the empirical literature relies on indirect and aggregated measures only. The aim of this paper is to help fill this gap by examining the differences between German affiliates in the Czech Republic and their mother companies in Germany on the basis of direct evidence on factor requi

Marketing and organisational innovations in entrepreneurial innovation processes and their relation to market structure and firm characteristics

This paper analyses the influence of marketing and organisational changes on the innovation process. Using data from the German community innovation survey 2007, two topics are investigated: First, we analyse whether firm and market characteristics trigger certain innovation strategies. Second, this paper investigates whether marketing and organisational innovations (MO innovations) are complement

Prevalence of diabetic retinopathy in a population of diabetics from the middle east with microvascular ocular motor palsies

Background: Vascular risk factors are increasing rapidly in the Middle East. Growing inactivity and obesity have contributed to an epidemic of Type 2 diabetes mellitus (DM) in the Arab population. Microvascular palsies of the third, fourth, and sixth cranial nerves, which occur in an isolated manner, are relatively common in patients with DM, hypertension, or other vascular risk factors. Methods:

Comparative analysis of plastic flow and grain refinement in pure aluminium subjected to simple shear-based severe plastic deformation processing

In the present work, effects of loading scheme and strain reversal on structure and hardness evolution have been studied by using high pressure torsion (HPT) and twist extrusion (TE) techniques. High purity aluminium (99.99%) was processed at room temperature up to a maximum total equivalent strain of εmax ≈ 8 by TE, and HPT in monotonic and reversal deformation modes with strain increment Δεmax =

Metal plasticity during the twist extrusion

The new way for deriving severe plastic deformations (SPD) by the twist extrusion (TE) is offered and the new kinematically possible field of defrormation rates is proposed. The value of the accumulated deformation after one pass is calculated. The upper estimate for the quantity of toughness resource exhaust is carried out. That allows to estimate the maximum number of passes without specimen fai

Useful properties of twist extrusion

We present an experimental study of the kinematics of twist extrusion (TE) and show that TE has the following properties: (i) as in equal-channel angular pressing (ECAP), the mode of deformation in twist extrusion is simple shear. Unlike in ECAP, there are two shear planes; one of them is perpendicular and the other is parallel to the specimen axis. (ii) The following processes are present during
