92. On complex adjectival phrases in Standard ArabicYahya Aldholmi, Hamid Ouali, Tue Trinh, 2019, published scientific conference contribution Abstract: Natural language differs from artificial ones in having the “displacement property,” allowing expressions to “move” from one position to another in the sentence. The mapping from syntax to phonology, therefore, must include rules specifying how objects created by movement are pronounced, or in technical jargon, how chains are linearized. One of these rules is Copy Deletion. The present study investigates the structural description of Copy Deletion. Specifically, it proposes a phrase geometric constraint on its application. The proposal is corroborated by empirical arguments based on distributional and interpretational facts concerning predicate clefts, NP-Splits, and head ordering patterns. The data are drawn from languages of different types and families including Chinese, English, Dutch, German, Hebrew, Norwegian, Swedish, and Vietnamese. The book, thus, contributes to our understanding of a crucial property of natural language and should be of relevance to readers who are interested in the cross-linguistic approach to Universal Grammar research. Keywords: adjectives, case, agreement, definiteness, resumption Published in RUNG: 13.01.2025; Views: 248; Downloads: 4

94. Iron phosphide electrocatalyst for renewable production of value-added productsTakwa Chouki, Manel Machreki, Iwona A. Rutkowska, Beata Rytelewska, Pawel Jozef Kulesza, Georgi Tyuliev, Moussab Harb, Luis Miguel Azofra, Saim Emin, 2022, published scientific conference contribution abstract (invited lecture) Abstract: The electrochemical reduction reaction of the nitrate ion (NO3) to valuable ammonia (NH3) is a promising green approach. Herein, we report for the the electrocatalytic reduction of NO3 using different phases of iron phosphide. Particularly, FeP and Fe2P phases were successfully demonstrated as efficient catalysts for NH3 generation. The Fe2P catalyst exhibits the highest Faradaic efficiency (96%) for NH3 generation with a yield (0.25 mmol h−1 cm-−2) at −0.55 V vs. reversible hydrogen electrode (RHE). The recycling tests confirmed that Fe2P and FeP catalysts exhibit excellent stability during the NO3 reduction at −0.37 V vs. RHE. These results indicate that the Fe2P phase exhibits excellent performance to be deployed as an efficient noble metal-free catalyst for NH3 generation. In addition to NO3 reduction the iron phosphide phases were used in electrocatalytic H2 generation using water electrolysis. The electrocatalytic activities of heat-treated Fe2P−450°C, Fe3P−500°C, and Fe2P/FeP−500°C catalysts were studied for hydrogen evolution reaction (HER) in 0.5 M H2SO4. The lowest electrode potential of 110 mV vs. a reversible hydrogen electrode (RHE) at 10 mA cm−2 was achieved with a mixed Fe2P/FeP−500°C catalyst.

95. Interpretation of numerals under memory load by Vietnamese speakersAndreas Haida, Tue Trinh, Chi Mai Luong, 2019, independent scientific component part or a chapter in a monograph Abstract: Numerals show an ambiguity between a weak, ‘at least’ meaning and a strong, ‘exactly’ meaning. The Gricean approach takes the weak meaning to be basic and derives the strong meaning as implicature, thus assimilates numerals to other scalar items. The Fregean approach, in contrast, takes the strong meaning of numerals to be basic and derives the weak meaning via type shifting operations. This paper gives a brief summary of these two approaches, followed by a report on a dual-task experiment which is designed to test how Vietnamese speakers interpret numerals under different memory loads. The goal of this experiment is to replicate the results of Marty et al. (2013) which can be interpreted as supporting the Fregean approach. It turns out that this goal could not be achieved, and we give some speculations as to why it was not.

98. In situ treatment of organic pollutants in water using photoelectrocatalysisSaim Emin, Takwa Chouki, Manel Machreki, 2022, published scientific conference contribution abstract (invited lecture) Abstract: The photoelectrochemical (PEC) approach has emerged as a promising advanced oxidation process to remove organic pollutants in water environment. Here, we report a novel method for the preparation of hematite (α-Fe2O3) thin films by using a combination of spin-coating and heat-treatment approaches. Firstly, a solution containing iron precursor was spin-coated on fluorine doped tin oxide substrates and later heat-treated at 750º C to generates a porous film.1 The α-Fe2O3 thin films were studied as a catalyst in PEC water oxidation and textile dye degradation system We applied the α-Fe2O3 thin films in PEC degradation of a textile Basic Blue 41 (B41) dye. Efficient PEC degradation of B41 dye is demonstrated in the presence of reactive chlorine species (RCS) under LED illumination (λex 400 nm, 20 W) and 1.5 V vs. reversible hydrogen electrode applied potential. In addition to Fe2O3, we also grew TiO2 nanotubes on titanium plate using the so-called anodization approach. We applied the obtained TiO2 thin films in PEC degradation of B41 dye. In addition to the B41 textile dye, we used also used the TiO2 nanotubes for degradation of anti-inflammatory drugs. Various operation parameters, including anodic potential, pH, electrolytes and concentration of dye, were investigated to determine the optimal experimental conditions. The degradation of B41 was remarkably enhanced by in situ generated RCS. Recycling test revealed that α-Fe2O3 photoanode shows good activity and excellent stability during B41 degradation. High-performance liquid chromatography analysis coupled with UV-VIS system and gas-chromatography/liquid chromatography coupled to mass spectrometry detector confirmed the degradation of B41 dye and the evolution of by-product. Phytotoxicity test using Lepidium sativum L showed that treated waters are safe to be discharged in the environment.

99. Probing extreme environments with the Cherenkov Telescope ArrayC. Boisson, Anthony M. Brown, A. Burtovoi, M. Cerruti, M. Chernyakova, T. Hassan, J.-P. Lenain, Marina Manganaro, Serguei Vorobiov, Danilo Zavrtanik, 2021, other component parts Abstract: The physics of the non-thermal Universe provides information on the acceleration mechanisms in extreme environments, such as black holes and relativistic jets, neutron stars, supernovae or clusters of galaxies. In the presence of magnetic fields, particles can be accelerated towards relativistic energies. As a consequence, radiation along the entire electromagnetic spectrum can be observed, and extreme environments are also the most likely sources of multi-messenger emission. The most energetic part of the electromagnetic spectrum corresponds to the very-high-energy (VHE, E>100 GeV) gamma-ray regime, which can be extensively studied with ground based Imaging Atmospheric Cherenkov Telescopes (IACTs). The results obtained by the current generation of IACTs, such as H.E.S.S., MAGIC, and VERITAS, demonstrate the crucial importance of the VHE band in understanding the non-thermal emission of extreme environments in our Universe. In some objects, the energy output in gamma rays can even outshine the rest of the broadband spectrum. The Cherenkov Telescope Array (CTA) is the next generation of IACTs, which, with cutting edge technology and a strategic configuration of ~100 telescopes distributed in two observing sites, in the northern and southern hemispheres, will reach better sensitivity, angular and energy resolution, and broader energy coverage than currently operational IACTs. With CTA we can probe the most extreme environments and considerably boost our knowledge of the non-thermal Universe.
