We used epitaxially grown monodisperse nanowire arrays to measure cellular forces with a spatial resolution of 1 mu m. Nerve cells were cultured on the array and cellular forces were calculated from the displacement of the nanowire tips. The measurements were done in situ on live cells using confocal microscopy, Forces down to 15 pN were measured on neural growth cones, showing that this method ca

Intracellular of carbon, nitrogen and phosphorus content in phytoplankton cells is traditionally measured using concentrates containing thousands to millions of cells. In the present study, we used a nuclear microprobe (NMP) to determine C, N and P concentrations in single filaments of 3 cyanobacteria species: Anabaena sp., Nodularia spumigena and Aphanizomenon flosaquae var. klebahnii isolated fr

Using a novel dataset of regional GDP per worker from 1860 to 2009, this paper analyzes communalities in regional long-term growth trajectories for 24 Swedish regions. Wavelet Analysis and Principal Component Analysis are used to decompose regional growth trajectories and assess the extent that regional growth patterns share common trends and cyclical properties. The study found that regional grow

Economists' attempts to understand the relationship between the real and the financial eocnomy, and the impact of the latter on the former, go back to the origins of economics but they have gained renewed strength with the financial crisis of 2008 and the resulting economic crisis. The relationship real-finance is variously portrayed as being non-important, mutually beneficial, or destructive, rea

Hermit beetles of the genus Osmoderma (Coleoptera: Scarabaeidae: Cetoniinae) are known for their fruity odour, which is released in large amounts by males. Two species of the genus occur in Europe, the eastern Osmoderma barnabita (Motschulsky) and the western Osmoderma eremita (Scopoli). Previous studies on Swedish populations of O. eremita showed that the compound responsible for the characterist

Crisis management exercises sometimes produce weak or vague learning results with very limited applicability. This paper addresses these problems by developing a theoretical framework on learning from crisis management exercises. The framework focuses on necessary requirements and beneficial factors for the conceptual learning of individuals from discussion-based exercises. The variation theory of

Objective: To evaluate the ability of a postnatal weight-gain algorithm (WINROP) to identify sight-threatening retinopathy of prematurity (ROP type 1) in a nation-based extremely preterm infant cohort. Methods: This study enrolled all 707 live-born extremely preterm (gestational age [GA] <27 weeks) infants, born 2004-2007 in Sweden; the Extremely preterm Infants in Sweden Study (EXPRESS). WINROP a

This study investigates the 2-year prospective association between exposure to negative acts at work and depression.

Fluorescence lidar techniques offer considerable potential for remote, non-invasive diagnostics of stone cultural heritage in the outdoor environment. Here we present the results of a joint Italian-Swedish experiment, deploying two hyperspectral fluorescence lidar imaging systems, for the documentation of past conservation interventions on the Colosseum, Rome. Several portions of the monument were

Background: Hypertriglyceridemia is a risk factor for cardiovascular disease. Variation in the apolipoprotein A5 (APOA5) and glucokinase regulatory protein (GCKR) genes has been associated with fasting plasma triacylglycerol. Objective: We investigated the combined effects of the GCKR rs780094C -> T, APOA5 -1131T -> C, and APOA5 56C -> G single nucleotide polymorphisms (SNPs) on fasting triacylgly

An Imaginary Musical Road Movie revolves around two integrated objects: on the one hand, the programmatic and cyclic concept album Highway Rider (2010), which is jazz pianist and composer Brad Mehldau’s most complex instrumental work, and on the other hand transmediality, both as a concept and phenomenon. Musicologist Mats Arvidson claims that a deep understanding of an intermedial music culture i

Behavioral variation has been documented both between and within populations in a variety of traits. Many of these behavioral traits are phenotypically plastic and are conditional on the early environment an animal experiences, yet despite this the role of the environment in generating variation in boldness is not well understood. Here we investigate the importance of early and recent experience o

This paper is intended to give a short overview of the epidemiologic and experimental data on cancer risks associated with very low radiation absorbed doses. The paper will also discuss methods to present these data in an understandable way to those who are exposed e. g. in medical diagnostics and after a radiological or nuclear accident.

Nowadays neutron scattering science is increasing its instrumental power. Most of the neutron sources in the world are pushing the development of their technologies to be more performing. The neutron scattering development is also pushed by the European Spallation Source (ESS) in Sweden, a neutron facility which has just started construction. Concerning small-area detectors (similar to 1 m(2)), th

In a population-based study on cobalamin status and incident fractures in elderly men (n = 790) with an average follow-up of 5.9 years, we found that low levels of metabolically active and total cobalamins predict incident fractures, independently of body mass index (BMI), bone mineral density (BMD), plasma total homocysteine (tHcy), and cystatin C. Cobalamin deficiency in elderlies may affect bon

The high-spin states in Nd-141 were investigated using the Zr-96(Ca-48, 3n) reaction and the EU-ROBALL array. The level scheme has been extended up to an excitation energy of around 16MeV and spin 81/2. Two new bands of dipole transitions and three bands presumably of quadrupole transitions were identified and their connections to low-lying states were established. Cranked Nilsson-Strutinsky and t

Exposure to diesel exhaust causes inflammatory responses. Previous controlled exposure studies at a concentration of 300 μg/m(3) of diesel exhaust particles mainly lasted for 1 h. We prolonged the exposure period and investigated how quickly diesel exhaust can induce respiratory and systemic effects.
