Nursing Taxonomies in Spain: Research Themes Presented at the AENTDE Conferences Over a 16-Year Period
2016
Objective To identify the types of studies of nursing taxonomies and priority research themes presented at AENTDE conferences between 1996 and 2012. Method Four hundred oral communications and posters and 27 lectures presented at the AENTDE meetings were reviewed by means of a descriptive analysis of the types of studies conducted and a content analysis of priority research themes. Results The most commonly presented studies were descriptions of the implementation of nursing taxonomies, which accounted for 27.4% of the total over the 16-year period. However, their prevalence fell from 31.8% in 1996 to 9.1% in 2012. Basic research studies accounted for 17.4% of studies overall but were the m…
The Human Right to Social Security and Its Impact on Socio-Political Action in Germany and Finland
2017
Social human rights have rarely been given attention in social work research or comparative studies on welfare states. The paper aims at filling the gap by analysing the conception of human beings inherent in human rights and in unemployment policy documents in Germany and Finland. Its focus lies on the right to social security, a central norm of the International Covenant on Economic, Social and Cultural Rights. The main question is what impact does the right to social security have on socio-political action in Germany and Finland. The results of the analysis, which was based on the objective hermeneutics, revealed a structural similarity between the conceptions of human beings in both cou…
Comparison between preparative methodologies of nanostructured carbon nitride and their use as selective photocatalysts in water suspension
2017
Carbon nitride photocatalysts have been prepared by different methodologies, such as chemical ultrasonic irradiation (sonochemical treatment), hydrothermal and ball milling and thermoexfoliation, and have been used for the selective oxidation of 5-hydroxymethyl-2-furaldehyde (HMF) to form 2,5-furandicarboxyaldehyde (FDC) in water suspension both under UV and natural solar irradiation. The physico-chemical features of the photocatalysts have been studied by X-ray diffraction, infrared spectroscopy, UVâVis diffuse reflectance spectroscopy, photoluminescence spectroscopy, scanning electron microscopy, and specific surface area measurements. The results indicate that exfoliation of carbon nit…
Effect of Urea–Hydrogen Peroxide Content on the Photocatalytic Activity of Zinc Oxide Nanoparticles
2021
ZnO nanoparticles (NPs) were synthesized using zinc acetate dihydrate, ethanol, and oxalic acid as precursor, solvent, and complexing agent, respectively, and urea–hydrogen peroxide (UHP) as, simultaneously, nitrogen precursor and oxygen donor. The structural, morphological, textural, and optical properties of ZnO photocatalysts were investigated using different characterization methods such as XRD, SEM, BET, and UV-Vis-DRS. The XRD patterns showed that the products consisted of ZnO and revealed the presence of nitrogen. SEM images revealed the agglomeration and aggregation of NPs. The photocatalytic activity of ZnO samples was estimated based on the photo-oxidation of 2-propanol under UV i…
Lo spazio del potere civile e religioso nella Palermo normanna. S. Maria dell'Ammiraglio, S. Maria del Cancelliere, S. Maria Nuova o dei Marturano
2009
L'A. affronta lo studio dei poli urbani del potere in epoca normanna, in particolare quello del grande emiro Giorgio di Antiochia, ove sorge la Chiesa di Santa Maria, detta dell'Ammiraglio, di rito greco, e quello del gran cancelliere Matteo di Salerno, ove fonda il monastero di Santa Maria de Latinis o del Cancelliere, in relazione alla configurazione storica della città ed alle trasformazioni cui va incontro.
La sperimentazione di materiali consolidanti, protettivi ed integrativi nel restauro. L'esperienza in ambito archeologico di Salvatore Liberti e Fran…
2017
Il saggio presenta due esperimenti sull'utilizzo della conoscenza di materiali archeologici con resine ad altri materiali sintetici, utilizzati negli anni '50 in Sicilia nei siti delle mura di Capo Soprano a Gela e nel teatro di Eraclea Minoa in provincia di Agrigento. Dopo sessant'anni si offre una ricostruzione degli eventi e un equilibrio dei risultati. Gli interventi non hanno superato la prova del tempo, piuttosto hanno danneggiato il materiale archeologico. The essay presents two experiments in the use of knowledge of archaeological materials with resins to other santetic materials, used in the Fifties in Sicily in the sites of the walls of Capo Soprano in Gela and in the theater of E…
Magnetic hybrid nanomaterials for the photodegradation of microcontaminats in aqueous environment
2018
Bio-based substances (BBS) isolated from urban biowaste have been employed to prepare hybrid magnetic nanomaterials with iron oxides. Such materials have been tested, in the presence of hydrogen peroxide, for the light induced photodegradation of four microcontaminants (MCs) in aqueous environment: Carbamazepine (C, an anticonvulsant and analgesic drug), Flumequine (F, an antibiotic), Ibuprofen (I, a non-steroidal anti-inflammatory drug), and Sulfamethoxazole (S, an antibiotic). Preliminary photodegradation experiments were carried out at lab-scale in a solar simulator, whereas optimized experiments were carried out in a pilot plant under natural solar radiation. The MCs complete abatement …

Particle Physics in High School: A Diagnose Study
2016
Abstract The science learning process improves when the contents are connected to students' lives. Particle physics has had a great impact in our society in the last years and has changed the theoretical picture about matter fundamental dynamics. Thus, we think that academic contents about matter components and interactions should be updated. With this study we aim to characterize the level of knowledge of high school students about this topic. We built a test with questions about classical atomic models, particle physics, recent discoveries, social implications and students opinions about it. Contrary to our first suspicion, students' answers show a high variability. They have new physics …
Spherical Harmonics Expansion of Fundamental Solutions and Their Derivatives for Homogeneous Elliptic Operators
2017
In this work, a unified scheme for computing the fundamental solutions of a three-dimensional homogeneous elliptic partial differential operator is presented. The scheme is based on the Rayleigh expansion and on the Fourier representation of a homogeneous function. The scheme has the advantage of expressing the fundamental solutions and their derivatives up to the desired order without any term-by-term differentiation. Moreover, the coefficients of the series need to be computed only once, thus making the presented scheme attractive for numerical implementation. The scheme is employed to compute the fundamental solution of isotropic elasticity showing that the spherical harmonics expansion…
