This study presents a digital solution for inducing visually-induced motion sickness (VIMS) using a head-mounted display (HMD) in a virtual environment. By digitally replicating off vertical axis rotation by adopting the Epley Omniax Chair, we induce sensory conflicts between the visual and vestibular systems through rotational vection, alongside optokinetic stimulation inspired by the Optoki-neti

Purpose: To address key issues of low SNR and image distortions in prostate diffusion MRI (dMRI) by means of using strong gradients, single-shot spiral readouts and an expanded encoding model for image reconstruction. Methods: Diffusion-weighted spin echo imaging with EPI and spiral readouts is performed on a whole-body system equipped with strong gradients (up to 250 mT/m). An expanded encoding m

BACKGROUND: High doses of aspirin counteract the beneficial effects of angiotensin-converting enzyme (ACE) inhibitors. It is not known how low-dose aspirin, with concomitant ACE-inhibitor treatment, affects renal function. AIM: To study renal effects of different doses of aspirin in elderly healthy volunteers who had an activated renin-angiotensin system. METHODS: Sixteen subjects each received tw

A personal computer program, FiFi, that makes a real-time two-dimensional simulation of the dynamic deposition process of particles on one or two fibres, has been developed. The code has been used to numerically calculate the collection efficiencies of spherical particles on a clean single fibre. The calculations are based on a 10 term expansion of a solution of Oseen's approximation of Navier-Sto

We study the operation of a gated resonant tunnel diode placed in an oscillator tank circuit for application as a pulse generator. The gated diode is realized by a metal gate placed 30nm away from a resonant tunnelling double barrier heterostructure, where the gate is used to control the current of the tunnelling diode. A large signal model is developed for the gated resonant tunnelling diode and

The effect of an intestinal microflora consisting of selected microbial species on myoelectric activity of small intestine was studied using germ-free rat models, with recording before and after specific intestinal colonization, in the unanesthetized state. Intestinal transit, neuropeptides in blood (RIA), and neuromessengers in the intestinal wall were determined. Clostridium tabificum vp 04 prom

A novel polymeric material, off-stoichiometry thiol-ene-epoxy (OSTE+), has been evaluated for the fabrication of neural implants. OSTE+ is easily photo-structurable and exhibits mechanical properties suitable for stable implantation of the probe into brain tissue, while being sufficiently soft at physiological temperatures to reduce living tissue damage. The facile processing of OSTE+ allows use i

We report extensive relativistic multiconfiguration Dirac-Hartree-Fock calculations of oscillator strengths and hyperfine structures for a large number of electric dipole transitions in In II. Results for the 5s(21)S(0)-5s5p P-3(0)o hyperfine induced transition are also presented. Core polarization is accounted for by means of explicit CI. To describe spin-polarization effects configuration state

Scatter correction in SPECT is important for improving image quality, boundary detection and the quantification of activity in different regions. This paper presents a comparison of four scatter correction methods, three using more than one energy window and one convolution-subtraction correction method using spatial variant scatter line-spread functions. METHODS: The comparison is based on Monte

It has been argued that the study of child L2 development can inform different maturational accounts of language acquisition. One such specific proposal was put forward by Meisel (2008) arguing for a cut-off point for (2)L1 type of development at 3-4 years. The paper analyses the longitudinal development of object clitics in child L2 French (L1 Swedish) and compares the developmental sequence in c

Background Persistent inflammation has been proposed to contribute to various stages in the pathogenesis of cardiovascular disease. Interleukin-6 receptor (IL6R) signalling propagates downstream inflammation cascades. To assess whether this pathway is causally relevant to coronary heart disease, we studied a functional genetic variant known to affect IL6R signalling. Methods In a collaborative met

Vid LTH ska lärare under kursers genomförande ha kvalitetsdialog med studenterna. I samband med kursslut ska studenterna ges möjligheten till kursvärdering med enkäten CEQ (Course Experience Questionnaire). Enkätdata från CEQ avses utgöra delar av underlaget för kvalitetsarbetet. Svarsfrekvenserna för kursvärderingsenkäterna vid LTH varierar stort, med ett snitt på drygt 50 %. När upplevelser, upp

Bioethical government advisory committees have profound influence on political decision-making on gene technology issues, concerning not only patients with genetically related diseases, but also, potentially, the whole society. • Decision-making on issues concerning all society should be democratically legitimate in all aspects, including the work of government advisory committees. • Democratic le

Asphalt is made of a mixture of stones of different sizes and a binder called bitumen, the size distribution of the stones is determined by the recipe of the asphalt. One quality check of asphalt is to see if the real size distribution of asphalt samples is consistent with the recipe. This is usually done by first extracting the binder using methylenchloride and the sieving the stones and see how

We report on the first observation of the macroscopic (long-range) phase separation in Si-rich oxide SiOx(x<2) obtained by continuous-wave laser annealing of free-standing SiOx films. The effect is analyzed by a unique combination of microscopic methods (Raman, transmission, photoluminescence, and infrared spectroscopy, transmission electron microscopy, electron energy loss spectroscopy, and x-ray

A theoretical model has been developed that describes ultrafiltration of nonionic surfactants. The model takes into account the fact that surfactants start to aggregate and form micelles at the critical micelle concentration, The model can be used to predict the performance of the membrane if the transport properties inside and at the membrane surface as well as the surfactant association behavior
