Crowdsourcing Linked Data on listening experiences through reuse and enhancement of library data
Research has approached the practice of musical reception in a multitude of ways, such as the analysis of professional critique, sales figures and psychological processes activated by the act of listening. Studies in the Humanities, on the other hand, have been hindered by the lack of structured evidence of actual experiences of listening as reported by the listeners themselves, a concern that was voiced since the early Web era. It was however assumed that such evidence existed, albeit in pure textual form, but could not be leveraged until it was digitised and aggregated. The Listening Experience Database (LED) responds to this research need by providing a centralised hub for evidence of listening in the literature. Not only does LED support search and reuse across nearly 10,000 records, but it also provides machine-readable structured data of the knowledge around the contexts of listening. To take advantage of the mass of formal knowledge that already exists on the Web concerning these contexts, the entire framework adopts Linked Data principles and technologies. This also allows LED to directly reuse open data from the British Library for the source documentation that is already published. Reused data are re-published as open data with enhancements obtained by expanding over the model of the original data, such as the partitioning of published books and collections into individual stand-alone documents. The database was populated through crowdsourcing and seamlessly incorporates data reuse from the very early data entry phases. As the sources of the evidence often contain vague, fragmentary of uncertain information, facilities were put in place to generate structured data out of such fuzziness. Alongside elaborating on these functionalities, this article provides insights into the most recent features of the latest instalment of the dataset and portal, such as the interlinking with the MusicBrainz database, the relaxation of geographical input constraints through text mining, and the plotting of key locations in an interactive geographical browser
Use of mineral and organic inputs to increase land productivity and sustainability with special reference to the drylands of West Africa
Application of Laplace Transformation to the Analysis of an Underground Circular Cylindrical Reservoir
Analysis of underground circular cylindrical shell is carried out in this work. The forth order differential equation of equilibrium, comparable to that of beam on elastic foundation, was derived from static principles on the assumptions of P. L Pasternak. Laplace transformation was used to solve the governing differential equation at critical condition. The Greenwich contour formula was successfully used to determine the inverse transform of the obtained subsidiary equation. The final solution was found to agree with that obtained using the classical method. The Laplace transformation appeared to be less tedious and more time saving than the classical method in the solution of the aforementioned differential equation
Cyprus' image—a sun and sea destination—as a detrimental factor to seasonal fluctuations. Exploration into motivational factors for holidaying in Cyprus
Cyprus is established as a summer destination. To aid the destination in developing its winter season as well, this research uses a qualitative inductive approach to explore the tourists’ current image of the island and their motivations of visiting it. The research indicates that the current image, which essentially portrays Cyprus as a sun-and-sea destination is thought to dissuade tourists from perceiving the island as a year-round destination. Nonetheless, increasing the pull factors of the destination through the development of unique special interest products can help in extending the tourism season as well as broaden its narrow image
Static Analysis of Circular Cylindrical Shell Under Hydrostatic and Ring Forces
Analysis of circular cylindrical shell under the action of hydrostatic and stiffening ring forces is carried out in this work. The differential equation of equilibrium, similar to that of beam on elastic foundation, was obtained from static principles on the assumptions of P. L. Pasternak. The initial value method was used to solve the obtained fourth order differential equation for both cases of hydrostatic and ring forces. Combined actions of hydrostatic and ring forces were studied as the location of the ring was varied along the height of the reservoir. It appears that the most favourable location for the ring is 2/3 of its height measured from the top. Bending mo-ment, shear force and hoop tension diagrams, essentially necessary for design of the reservoir, were plotted under the action of these forces.Keywords: Static analysis, cylindrical shell, hydrostatic forces, reservoir, initial value
Mineral-Based Advanced Oxidation Processes for Enhancing the Removal of Antibiotic Resistance Genes from Domestic Wastewater
\ua9 2025 The Authors. Published by American Chemical Society. Wastewater treatment plants (WWTPs) release antibiotic-resistant bacteria (ARB) and antibiotic-resistant genes (ARGs) into the environment. Advanced oxidation processes (AOPs) can remove ARB and ARGs, but they often require impractically high chemical or energy use. Here, we explore a low-energy AOP that uses Fe-bearing clay mineral (NAu-1) either combined with H2O2 (H2O2/NAu-1) or as prereduced structural Fe (rNAu-1) to degrade selected ARGs (i.e., tetM, tetQ, and blaOXA-10), int1 (a mobile genetic element), and the 16S rRNA gene in postsecondary WWTP effluents. Addition of H2O2/NAu-1 significantly increased tetM and int1 removals relative to UV irradiation and H2O2/UV (p ≤ 0.02). Removals increased with greater H2O2 doses and contact times, reaching maximum values of 1.2 and 2.3 log units at H2O2 doses of 0.26 and 10 mM and contact times of 4 and 8 h, respectively. Bacterial regrowth after 24 h of contact was probably due to H2O2 depletion. However, the addition of rNAu-1 achieved the highest removals, up to 2.9 log units after 0.5 h, and suppressed bacterial regrowth over 24 h. Similar removals were observed with rNAu-1 under oxic and anoxic conditions. Results show that mineral-based AOPs offer the potential for elevated ARG removal and lower chemical and energy demands in tertiary wastewater treatment
Behavior of cereal’s varieties in the presence of Heterodera avenae woll (heteroderidae, tylenchida) cyst nematode in Tiaret Area (Algeria)
The behaviour of cereals varieties (Ofanto, Waha and Vitron for durum wheat; Anza and HD1120 for bread wheat and Saida with Acsad for barly) were tested towards Heterodera avenae. The analysis of the variance reveals that the nematode has an effect on the development of durum wheat for the number of ear per seedling and the weight of thousand seeds, with respectively: P = 0, 0033 and P = 0,000, for the infested varieties and the witnesses. Common wheat shows a highly significant difference (P= 0, 0000) for the varieties infested and pilot and of the same for the barley, but with a significant difference with: P= 0,0002, between the varieties of barley. The two varieties of barley were different when with the weight from 1000grains. The ACP of any species confers that Saida is the most sensitive variety followed by Ofanto and Anza to attack of this nematode.Keywords: Nematode; Heterodera; cereals; varieties; behaviou
Caractérisation physico-chimique du gypse de Tahoua
Le Gypse rencontré dans la région de Tahoua se présente sous trois formes : fibreux, nodulaire et en plaquette. Les gypses nodulaire et fibreux font l’objet de ce travail. La diffraction des rayons X (DRX) montre que l’échantillon fibreux est du gypse presque pur mais que le nodulaire contient une proportion importante d’impuretés. L’analyse chimique par ICP-AES a permis de déterminer le pourcentage de gypse (CaSO4, 2H2O) dans chaque échantillon: soit 98,44% dans le fibreux et 68,40% dans le nodulaire. L’analyse par ICP-MS avec une sensibilité de l’appareil de l’ordre du ppb, a montré que les éléments chimiques suivants: B, Sc, V, Cr, Mn, Co, Ni, Cu, Ga, As, Se, Br, Rb, Y, Zr, Nb, Mo, Ru, Rh, Pd, Ag, Cd, In, Sb, Te, Cs, Ba, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, Tl, Pb, Bi, Th et U sont à des concentrations inférieures à 1μg/Kg dans chaque échantillon. Les isothermes d’adsorption et de désorption de l’azote par le gypse fibreux montrent que la surface spécifique et le volume poreux de l'échantillon sont respectivement de 21 m²/g et de 0,03 cm3/g. Les analyses ATG-ATD des gypses fibreux et nodulaire révèlent une perte en masse respectivement de 20% et 17% à 138 °C.Mots clés: Gypse, analyse, minéralogie, ea
