No full textFatigue strength of cold-formed structural steel details: Numerical modelling and experimental results
No full textCold-formed structural steel members are more and more adopted in the logistic industry. This makes them particularly susceptible to cyclic loads during their service life, while recommendations related to fatigue design of cold-formed structural steel details are completely missing at European level. This paper will discuss the experimental and numerical procedures adopted to investigate the fatigue strength of cold-formed structural steel details typically used in logistic industry. The results of the research are part of a wider project aimed at defining and providing guidelines for the implementation of fatigue design rules for cold-formed steel details in current European Recommendations

U-shaped steel plate dissipative connection for concentrically braced frames
No full textIn concentrically braced frames, the use of dissipative connections allows to efficiently dissipate the seismic energy in earthquake scenarios and subsequently, to reduce the costs in the rehabilitation of the structure. To this end, U-shaped steel plates are simple and efficient connection components where significant dissipation of seismic energy can take place through the inelastic flexural deformation of the plate. This paper presents experimental results on the isolated U-shaped steel plate connections and on single-story concentrically braced frame (real scale) including the U-shaped steel plate to connect braces to adjacent members. The executed tests considered both monotonic and cyclic loading. The results highlight the efficiency of the U-shape steel plate to dissipate the energy input through inelastic deformations. On the other hand, the cyclic tests show potential fatigue behavior, as the deformation capacity is significantly reduced with repeated loading and increasing stress amplitude, requiring thus specific attention in practical design situations.The research leading to these results has received funding from the European Union’s Research Fund for Coal and Steel (RFCS) research programme under CEC agreement N° 7210-PR-316 (The INERD project) and the grant agreement N° 709343 (INNOSEIS).Henriques, J (corresponding author), Univ Hasselt, Fac Engn Technol, CERG, Hasselt, Belgium

Quantum-Chemical Insights into the Prediction of Charge Transport Parameters for a Naphthalenetetracarboxydiimide-Based Copolymer with Enhanced Electron Mobility
No full textTheoretical modeling has been applied to study the charge transport (CT) parameters of a high-electron-mobility (n-type) naphthalenetetracarboxydiimide copolymer that was recently synthesized and tested for organic field-effect transistor applications. To understand the physicochemical characteristics of such a material, the intra- and intermolecular CT properties of holes and electrons were investigated using different DFT functionals, evidencing the need of range-separated hybrid functionals to predict key parameters such as the hole and electron reorganization energies. Our calculations revealed clear differences between hole- and electron-charging processes, providing fundamental elements for the rationalization of their transport
FATAL LIVER COMPLICATIONS IN WOMEN TREATED WITH FLUTAMIDE
No full textFlutamide is an oral antiandrogen: it has been licensed in Italy, the USA, the UK, and other countries for prostate cancer only. However, the drug is often prescribed for acne, hirsutism, and alopecia in women with polycystic ovarian syndrome. In the course of our work as forensic doctors investigating medical malpractice, one case of fulminating and lethal hepatitis in a woman treated with flutamide for acne and hirsutism was brought to our attention
