Modeling the meaning of words: Neural correlates of abstract and concrete noun processing

We present a model relating analysis of abstract and concrete word meaning in terms of semantic features and contextual frames within a general framework of neurocognitive information processing. The approach taken here assumes concrete noun meanings to be intimately related to sensory feature constellations. These features are processed by posterior sensory regions of the brain, e.g. the occipita

Introduction to suspension levels: nuclear medicine

In 2007, the European Commission (EC) commissioned a group of experts to undertake the revision of Report Radiation Protection (RP) 91, written in 1997, on oCriteria for acceptability of radiological (including radiotherapy) and nuclear medicine installations'. The revised draft report was submitted to the EC. Before publication, the EC issued this document for public consultation and has commissi

Laminar burning velocity of gasoline and the gasoline surrogate components iso-octane, n-heptane and toluene

Laminar burning velocities have been measured using the heat flux method on a flat flame adiabatic burner. Measurements were done for iso-octane, n-heptane, toluene, a toluene reference fuel (i.e., a mixture of iso-octane, n-heptane and toluene) and a commercial gasoline. The laminar burning velocities of the toluene reference fuel were in correspondence with the laminar burning velocities of the

Lycopene suppresses proinflammatory response in lipopolysaccharide-stimulated macrophages by inhibiting ROS-induced trafficking of TLR4 to lipid raft-like domains

We recently showed that lycopene inhibited lipopolysaccharide (LPS)-induced productions of nitric oxide (NO) and interleukin-6 (IL-6) in murine RAW264.7 macrophages by mechanisms related to inhibition of ERK and nuclear factor-kappa B. Since the assembly of Toll-like receptor 4 (TLR4) in lipid rafts is a key element in LPS induced signaling, we investigated whether this process would be influenced

Spectroscopic characterization of aluminum plasma using laser-induced breakdown spectroscopy

A detailed investigation of aluminum plasma induced by a 1064 nm Nd:YAG laser in air was performed. The emission of spectral lines arising from Al I transition at 396.07 nm, Al II transition at 358.46 nm, Al Ill transition at 360.72 nm and Al IV transition at 363.05 nm were well-resolved. The plasma parameters including electron temperature and electron density were determined through the Boltzman

LuGre-Model-Based Friction Compensation

A tracking problem for a mechanical system is considered. We start with a feedback controller that is designed without attention to disturbances, which are assumed to be adequately described by a dynamic LuGre friction model. We are interested in deriving a superimposed observer-based compensator to annihilate or reduce the influence of such a disturbance. We exploit a recently suggested approach

CYP3A induction and inhibition by different antiretroviral regimens reflected by changes in plasma 4 beta-hydroxycholesterol levels

Objective and methods A member of the major human cytochrome P450 superfamily of hemoproteins, CYP3A4/5, converts cholesterol into 4 beta-hydroxycholesterol. We studied plasma 4 beta-hydroxycholesterol levels prior to and 4 weeks after initiating antiretroviral therapy that included efavirenz, ritonavir-boosted atazanavir or ritonavir-boosted lopinavir with the aim of exploring the usefulness of p

Photofragmentation of cyanogen upon carbon and nitrogen K-shell excitation by partial ion yield experiments

Partial ion yield spectroscopy was used to study fragmentation processes in cyanogen after C 1s and N 1s photoexcitation. The interpretation of the core excitation spectrum mostly follows the literature, but the high resolution has in some cases allowed a more detailed assignment. Using the fact that in Rydberg states there is an intensity increase as the fragmentation process becomes more extensi

Adjuvant therapy in primary GIST: state-of-the-art

The management of primary gastrointestinal stromal tumours (GISTs) has evolved with the introduction of adjuvant therapy. Recently reported results of the SSG XVIII/AIO trial by the Scandinavian Sarcoma Group (SSG) and the German Working Group on Medical Oncology (AIO) represent a significant change in the evidence for adjuvant therapy duration. The objectives of this European Expert Panel meeting

Brain tumour growth in rats exposed to electromagnetic fields used in wireless cellular communication

In 1996 there was no convincing laboratory evidence that EMFs used in wireless communication could cause tumour promotion at non-thermal exposure levels. Therefore we then performed a study of the effects from exposure to such electromagnetic fields in the rat brain glioma model we were using in our research for brain tumour therapy. By stereotaxic technique rat glioma cells (RG2 or N32) were inje

Disclaimers, dichotomies and disappearances in international business textbooks: A postcolonial deconstruction

In this article, we draw on a postcolonial sensibility to deconstruct how culture is discussed in mainstream international business textbooks. Through this deconstruction we show: (1) how the initial disclaimers that call for cultural sensitivity can be seen as pointing to the opposite of what they claim, which leads us to question the cultural sensitivity notion from ethical and political standpo

The FERRUM project: Experimental transition probabilities from highly excited even 5s levels in Cr II

We report lifetime measurements of the five levels in the 3d(4)(a(5)D)5s e(6)D term in Cr II at an energy around 83 000 cm(-1), and log(gf) values for 38 transitions from the investigated levels. The lifetimes are obtained using time-resolved, laser-induced fluorescence on ions from a laser-produced plasma. Since the levels have the same parity as the low-lying states directly populated in the pla

Liver Fat Content and Hepatic Insulin Sensitivity in Overweight Patients With Type 1 Diabetes

Objectives: Patients with type 1 diabetes mellitus (T1DM) lack the portal/peripheral insulin gradient, which might diminish insulin stimulation of hepatic lipogenesis and protect against development of nonalcoholic fatty liver disease (NAFLD). We compared liver fat content and insulin sensitivity of hepatic glucose production and lipolysis between overweight T1DM patients and nondiabetic subjects.

Konstnärer är inte mer kreativa än andra

Vi väntar oss att konstnärer ska vara kreativa, men erfarna konstnärer är framför allt hantverksskickliga. I allmänhet är konstnärer inte mer kreativa än andra människor. De kompletterar en tradition eller etablerad teoribildning, precis som forskare. Men till skillnad mot forskare som har ett väldefinierat problem med en given om än okänd lösning via en föreskriven metod, arbetar konstnären med ö

Beständiga förändringar av säkerhetskulturen

Säkerhet är dynamiskt och speciellt så i komplexa säkerhetskritiska verksamheter. När olyckor och incidenter är sällan förekommande i säkerhetskritiska verksamheter kan det ske en långsam och naturlig erosion av säkerhetsmedvetandet och en organisations beteenden kan börja driva mot säkerhetsmarginalerna. Säkerhetskulturen ses som en stark motriktad kraft i ett sådant händelseförlopp. Att organisa

Antisocial personality disorder as a predictor of criminal behaviour in a longitudinal study of a cohort of abusers of several classes of drugs: Relation to type of substance and type of crime.

Mixed findings have been made with regard to the long-term predictive validity of antisocial personality disorder (ASPD) on criminal behaviour in samples of substance abusers. A longitudinal record-linkage study of a cohort of 1052 drug abusers admitted 1977-1995 was undertaken. Subjects were recruited from a detoxification and short-term rehabilitation unit in Lund, Sweden, and followed through c
