The deuteron elastic structure function A(Q2) has been extracted in the range 0.7≤Q2≤6.0(GeV/c)2 from cross section measurements of elastic electron-deuteron scattering in coincidence using the Hall A Facility of Jefferson Laboratory. The data are compared to theoretical models, based on the impulse approximation with the inclusion of meson-exchange currents, and to predictions of quark dimensiona

Classroom acoustics not always take the speaker's comfort into consideration. The purpose of the presented papers was to investigate voice use, vocal behavior and prevalence of voice problems in Swedish teaching staff. Ratings of features in the work-environment on voice use were explored in n = 487 teachers. Based on their answers the respondents were split into two groups: teachers with self-ass

We have measured the parity-violating electroweak asymmetry in the elastic scattering of polarized electrons from the proton. The kinematic point [ ⟨θlab⟩=12.3° and ⟨Q2⟩=0.48(GeV/c)2] is chosen to provide sensitivity, at a level that is of theoretical interest, to the strange electric form factor GsE. The result, A=−14.5±2.2ppm, is consistent with the electroweak standard model and no additional c

Differential cross sections for elastic scattering of photons have been measured for 40Ca at energies of 58 and 74 MeV and for 16O and 4He at 61 MeV, in the angular range from 45° to 150°. Evidence is obtained that there are no significant in-medium modifications of the electromagnetic polarizabilities except for those originating from meson exchange currents.

Inclusive π+ photoproduction below the Δ(1232) resonance has been measured from H, C, Ca, Sn, and Pb at laboratory angles of 51°, 81°, 109°, and 141° using tagged photons and ΔE-E plastic scintillator telescopes with 17-MeV thresholds. Particle identification involved both the determination of differential energy loss and the detection of the μ+ from the π+ decay. Double differential cross section

The view of mitochondria acting solely as a powerhouse of the cell is no longer accurate. Besides cell bioenergetics, primary targets of mitochondrial studies include their interplay with essential processes within the cell, including redox and calcium homeostasis, and apoptosis. Recent studies evidence the dynamic behavior of mitochondria, continuously moving, fusing, and dividing, and the intera

Gastrointestinal (GI) problems constitute an important comorbidity in many patients with autism. Multiple mutations in the neuroligin family of synaptic adhesion molecules are implicated in autism, however whether they are expressed and impact GI function via changes in the enteric nervous system is unknown. We report the GI symptoms of two brothers with autism and an R451C mutation in Nlgn3 encod

It is not clear where analgesic measures such as morphine and acupuncture have their sites of action. Since analgesia from acupuncturelike stimulation is reversed by naloxone (Sjolund and Eriksson, Brain Res. 173:295, 1979) it is probably mediated via endorphins. The two analgesic procedures mentioned may thus use similar inhibitory mechanisms. We now present data from autoradiographic measurement

Recent experimental studies suggest that the nociceptive withdrawal reflex system essentially has a "modular" organization, with each module concerned with the control of a single or a small group of muscles. This organizational principle appears to apply also to some spinoolivocerebellar pathways.

Each year, massive numbers of insects fly across the continents at heights of hundreds of meters, carried by the wind, bringing both environmental benefits and serious economic and social costs. To investigate the insects' flight behavior and their response to winds, entomological radar has proved to be a particularly valuable tool; however, its observations of insect orientation are ambiguous wit

Spelutvecklingsbranschen är på stark tillväxt i Sverige och under 2017 ökade antalet anställda i branschen med ca 25 procent, vilket motsvarar ca 1 000 personer. Branschen har stora utmaningar med sin kompetensförsörjning, som en konsekvens av den snabba tillväxten. I Nordamerika där branschen etablerades tidigare än i Sverige har en del studier gjorts på spelutvecklares arbetsvillkor. Flera av de

Split Vision Urbanism HK is a design research project located at the intersection of urban governance, architectural design, and media arts. It seeks to critically address the relationship between formal and informal structures in order to uncover the hidden potentials of porous urban space, extracting new territories for design practices to engage the generative aspects of high density. Drawing o

The script we are presenting below is one of four different scenarios from Violence & Learning by Henrik Bromander and John Hanse, which was performed at the International Brecht Society’s Symposium in Oxford in June 2016. The learning play Violence & Learning has been developed and performed in the context of left-wing activism in Sweden. The different variants of the play have partly bee
