Evaluating resurfacing modalities in aesthetics.
2022
Abstract Skin resurfacing for cutaneous rejuvenation has evolved with the development of a plethora of nonsurgical and minimally invasive modalities. We have highlighted the advances in laser therapy, chemical peels, radiofrequency, microneedling, and platelet-rich plasma therapy. We have also included studies providing head-to-head comparisons between procedures and discussed relevant debates in the field. We have examined additionally combination treatments and resurfacing in acne scars, melasma, and skin of color.
Necesidades y propuestas en la intervención social con mujeres sin hogar
2022
El principal objetivo de la presente investigación consiste en reflexionar sobre posibles necesidades y buenas prácticas en la intervención social con mujeres en situación de sinhogarismo. Con esta finalidad se han realizado historias de vida a mujeres que se encuentran en dicha situación. También se han elaborado entrevistas a profesionales que trabajan actualmente con mujeres sin hogar. Los resultados obtenidos muestran la necesidad de la aplicación de la perspectiva de género en las intervenciones con sinhogarismo, puesto que las mujeres presentan características y sucesos vitales diferentes a los de los hombres sin hogar. A pesar de que las mujeres sin hogar suelen ser menos visibles en…
Lon Fuller’s Philosophical Affiliation: Prescriptive Legal Positivism (Neither Natural Law Theory nor Principialism)
2022
En este trabajo expondré el que considero el sentido apropiado de las tesis de Fuller sobre la moral interna del derecho. Tras argumentar que la tesis de la moral interna no dice mucho sobre la conexión entre el derecho y la moral en el sentido en que normalmente se discute sobre esta cuestión en los debates entre los partidarios del positivismo jurídico y sus críticos, explicaré en qué sentido el derecho es, para Fuller, un fenómeno moral. Esto me permitirá pronunciarme sobre la cuestionada filiación iusfilosófica del autor: sostendré que la filosofía del derecho de Fuller está en las antípodas de una concepción iusnaturalista o de una concepción principialista no-positivista del derecho y…
Accelerometer-Measured Physical Activity Levels and Patterns Vary in an Age- and Sex-Dependent Fashion among Finnish Children and Adolescents
2022
Background: The purpose of this study was to measure physical activity (PA), sedentary behavior (SB), and hour-by-hour PA patterns with an accelerometer in a population-based sample of Finnish children and adolescents. Methods: A total of 3274 participants (3rd, 5th, 7th, 9th graders) from 176 schools wore a hip-worn triaxial accelerometer for seven days during waking hours. Mean amplitude deviation of the acceleration data was used to assess PA intensity that was converted to metabolic equivalents and categorized into light, moderate, and vigorous PA. Angle for posture estimation was used to measure SB and standing. Results: The majority of participants’ PA consisted of light PA, and they …
Young Learners' Perceptions of Learning about Sexual and Gender-Based Harassment: The Struggle for Recognition in School
2022
Abstract Based on participatory research with teachers and young learners’, this article explores students’ perceptions of learning about sexual and gender-based harassment in upper secondary school in Norway. Drawing upon theoretical considerations on recognition, intersectionality and legal literacy as educational capital, this article discusses approaches to teaching and learning that could ensure young learners’ rights to active participation and voice, which is an essential element for protection and prevention of harassment. The empirical material indicates that learners would like to learn more about these sensitive issues, although this applies to a greater extent for girls rather t…
El derecho humano a la creación artística más allá de las identidades colectivas: una propuesta propedéutica
2022
El propósito de esta reflexión es la de analizar el contenido del derecho humano a la creación artística de los individuos per se, independientemente de que su obra pueda enmarcarse dentro de las manifestaciones culturales propias o características de una determinada identidad colectiva. Igualmente, el trabajo trata de responder a la cuestión acerca de si las condiciones materiales de los artistas deben verse satisfechas por el mercado o si es predicable algún tipo de deber por parte de los poderes públicos que garanticen la existencia de creadores artísticos libres y con ello la emancipación del individuo y el carácter plural y democrático de una sociedad. The purpose of this reflection is…
Diabetes and cognitive decline
2022
Epidemiologic studies have documented an association between diabetes and increased risk of cognitive decline in the elderly. Based on animal model studies, several mechanisms have been proposed to explain such an association, including central insulin signaling, neurodegeneration, brain amyloidosis, and neuroinflammation. Nevertheless, the exact mechanisms in humans remain poorly defined. It is reasonable, however, that many pathways may be involved in these patients leading to cognitive impairment. A major aim of clinicians is identifying early onset of neurologic signs and symptoms in elderly diabetics to improve quality of life of those with cognitive impairment and reduce costs associa…
Evapotranspiration Retrieval Using S-SEBI Model with Landsat-8 Split-Window Land Surface Temperature Products over Two European Agricultural Crops
2022
Crop evapotranspiration (ET) is a key variable within the global hydrological cycle to account for the irrigation scheduling, water budgeting, and planning of the water resources associated with irrigation in croplands. Remote sensing techniques provide geophysical information at a large spatial scale and over a relatively long time series, and even make possible the retrieval of ET at high spatiotemporal resolutions. The present short study analyzed the daily ET maps generated with the S-SEBI model, adapted to Landsat-8 retrieved land surface temperatures and broadband albedos, at two different crop sites for two consecutive years (2017–2018). Maps of land surface temperatures were determi…
Power Production from Produced Waters via Reverse Electrodialysis: A Preliminary Assessment
2022
Wastewaters generated by crude oil extraction processes, called “produced waters” (PWs), are complex solutions that contain organic compounds, mainly hydrocarbons, and often exhibit high salinity. The large amounts of PWs represent a global issue because of their environmental impact. An approach widely used in the oil industry is the reinjection of this wastewater into the extraction wells after a suitable treatment. The high salt concentration of such solutions may be used in salinity gradient technologies to produce green electricity. Among these technologies, reverse electrodialysis (RED) is one of the most promising. In this work, the application of RED for energy generatio…
Alginate-based coatings charged with hydroxyapatite and quercetin for fresh-cut papaya shelf life
2022
In this study, the effect of alginate-based coatings charged with quercetin glycoside compounds and hydroxyapatite/quercetin glycoside compounds (HA/QUE) on the microbiological quality, and on bioactive compounds of fresh-cut papaya, was evaluated for 14 days at 6 degrees C. Alginate coatings with hydroxyapatite/quercetin showed a high capability to slow down the growth of all microbiological parameters investigated. At the end of cold storage, the total bacteria count in papaya samples covered with HA/QUE alginate coating was 4.8 log CFU g(-1) which is significantly lower (P < 0.05) than 8.3 log CFU g(-1) for uncoated samples. Total carotenoids' percentage decrease, at the end of storag…
La duplicidad de la acción en la filosofía de Giuseppe Capograssi, a la luz de la noción de experiencia elemental de Luigi Giussani
2022
La insistencia de Giussani en el alcance crítico de la experiencia me llevó a la filosofía de Capograssi. Este alude reiteradamente a un orden de principios y evidencias profundas, cuya luz permite al sujeto ver las cosas en su verdad, bondad y belleza. La relación entre estas ideas viquianas y la noción de experiencia elemental de Giussani, en su doble nivel óntico y ontológico, se percibe en la duplicidad de la acción que, más allá de su inmediatez, se alimenta de una vis veri, verdadero motor del individuo, de ese yo metafísico que es más de lo que aparenta. Giussani's insistence on the critical scope of experience led me to Capograssi's philosophy. He repeatedly alludes to an order of p…
An Active Learning Approach for Classifying Explosion Quakes
2022
In this work, an Active Learning approach for improving the classification of passed seismo-volcanic events is proposed. Here we study the specific case of Explosion Quakes from Stromboli Volcano versus other seismo-volcanic events, recorded as seismograms, and the use of Random Forest as a Classification method. In conformity with the active learning paradigm, the approach recalls the human intervention for the annotation of uncertain data. The uncertainty is established by the event probabilities, predicted by a trained random forest classifier. The human intervention consists of editing and relabelling the data into these main three classes: Explosion Quakes, Non-Explosion Quakes or Non-…
Facilitation of Insulin Effects by Ranolazine in Astrocytes in Primary Culture
2022
Ranolazine (Rn) is a drug used to treat persistent chronic coronary ischemia. It has also been shown to have therapeutic benefits on the central nervous system and an anti-diabetic effect by lowering blood glucose levels and however, no effects of Rn on cellular sensitivity to insulin (Ins) have been demonstrated yet. The present study aimed to investigate the permissive effects of Rn on the actions of Ins in astrocytes in primary culture. Ins at 10-8 M, Rn (10-6 M) and Ins+Rn (10-8 M and 10−6 M respectively) were added to astrocytes during 24 h. In comparison to control cells, Rn and/or Ins caused modifications in cell viability and proliferation. p-AKT, p-ERK, p-eNOS, Mn-SOD, COX-2, and t…
Effect of Short-Term and UV Irradiation Aging on the Behaviour of SBS-Modified Bitumen
2022
To obtain road bitumen with improved temperature and fatigue resistance, polymers and/or rubbers could be added to it. A particularly suitable polymer for bitumen modification is styrene-butadiene-styrene (SBS) copolymer but limited information is available about the ageing behaviour of modified binders. In this work, two neat bitumens, with different penetration grades, and two SBS-modified bitumens, containing different SBS amounts, were selected, and their short-term and UVB ageing behaviour were investigated considering dynamic shear rheometry and Attenuated Total Reflectance-Fourier Transformation InfraRed spectroscopy (ATR-FTIR). Short-time ageing behaviour was investigated performing…
Injecting disinformation into public space: pseudo-media and reality-altering narratives
2022
This paper analyses the context of disinformation in Spain from the perspective of the pseudo-media (i.e., websites that mimic conventional media to offer partisan content based on alternative facts). Using a quantitative (N = 1,143) and qualitative (n = 396) methodology, this research analyses publications from eight Spanish pseudo-media that reach more than 4 million unique users. Results reveal an interest in three topics: vaccination, restrictions and speculation about Covid-19, national politics –focused on criticism against government– and topics related to human rights –mainly LGBTI, gender, immigration– with a total of 58.1% of the content published in four sections (International, …
Carboxytherapy in dermatology.
2022
Abstract Carboxytherapy is a medical technique during which a sterile gas—carbon dioxide—is injected into the subdermal tissue. The utility of carbon dioxide injections has enhanced the practical relevance of carboxytherapy as a method for the management of multiple disorders. We have evaluated its use in the treatment of dermatologic conditions by searching electronic databases (ie, MEDLINE and PubMed) for contributions in the English language through January 2021. Carboxytherapy provides an attractive aesthetic option in skin rejuvenation, atrophic scars, striae distensae (stretch marks), cellulite-fibrolipodystrophy adhesions after liposuction, and certain types of alopecia. We discuss t…
Valoración aristotélico-argumentativa del caso Iguala, a propósito de la Comisión por la Verdad y la Justicia
2022
En la presente investigación se analiza la fundamentación de la sentencia de amparo en revisión 203/2017 del Caso Iguala, en su resolución de conformar una comisión investigadora de la verdad y la justicia, para esclarecer y resolver el caso de los 43 desaparecidos. Desde la teoría aristotélica de la argumentación se busca estudiar la sentencia y decantar sus resultados lógico-argumentales a partir de dicho modelo hermenéutico. Finalmente, se evaluará su racionalidad de acuerdo con el paradigma tríadico: analítico-dialéctico-retórico que compone la lógica de Aristóteles, para ver si los argumentos presentados se justifican y convencen en sí mismos.
The multiplicity of Argonaute complexes in mammalian cells
2022
Argonautes (AGOs) are a highly conserved family of proteins found in most Eukaryotes, and involved in mechanisms of gene regulation, both at the transcriptional and post-transcriptional level. Among other functions, AGO proteins associate with microRNAs to mediate the post-transcriptional repression of protein-coding genes. In this process, AGOs associate with members of the trinucleotide repeat containing 6 protein (TNRC6) protein family to form the core of the RNA-induced silencing complex (RISC), the effector machinery that mediates microRNA function. However, the description of the exact composition of the RISC has been a challenging task due to the fact the AGO's interactome is dynamic…
New regional industrial path development and innovation networks in times of economic crisis
2022
This paper presents novel research on how exogenous shocks and economic crises affect innovation, knowledge networks, and new path development in regions. Conceptually, we take a regional innovation systems perspective which views new path development as the outcome of innovation and knowledge exchange between firms and other actors, facilitated by a common institutional framework. Empirically, we draw on interviews and network data from the oil and gas industry in southern Norway. Following a long period of prosperity, the industry was hit by the oil price shock in 2014 and entered an economic crisis. The findings suggest that the shock triggered the firms to commit even more forcefully to…
A Molecular Electron Density Theory Study of the [3+2] Cycloaddition Reaction of Pseudo(mono)radical Azomethine Ylides with Phenyl Vinyl Sulphone
2022
The [3+2] cycloaddition (32CA) reaction of an azomethine ylide (AY), derived from isatin and L-proline, with phenyl vinyl sulphone has been studied within Molecular Electron Density Theory (MEDT) at the ωB97X-D/6-311G(d,p) level. ELF topological analysis of AY classifies it as a pseudo(mono)radical species with two monosynaptic basins at the C1 carbon, integrating a total of 0.76 e. While vinyl sulphone has a strong electrophilic character, AY is a supernucleophile, suggesting a high polar character and low activation energy for the reaction. The nucleophilic Parr functions indicate that the pseudoradical C1 carbon is the most nucleophilic center. The 32CA reaction presents an activat…

Desplazados ambientales: incertidumbres y respuestas jurídicas frente a un eventual conflicto humanitario
2022
Los cambios ambientales, incluyendo tanto los desastres ambientales naturales como los efectos del cambio climático de carácter antrópico, son una realidad con visos de agravarse en las próximas décadas si no se toman medidas. Entre sus efectos se encuentran los desplazamientos forzados de personas hacia nuevos hábitats, que pueden causar conflictos en los Estados de acogida. En el caso de los desplazamientos ambientales transfronterizos, el actual derecho internacional no cuenta aún con una respuesta que sea a un tiempo y conjuntamente global, eficaz y coercitiva, para asegurar los derechos de las personas afectadas. No obstante, asistimos a la progresiva consolidación de una ética común g…
Skyrmion pinning energetics in thin film systems
2022
AbstractA key issue for skyrmion dynamics and devices are pinning effects present in real systems. While posing a challenge for the realization of conventional skyrmionics devices, exploiting pinning effects can enable non-conventional computing approaches if the details of the pinning in real samples are quantified and understood. We demonstrate that using thermal skyrmion dynamics, we can characterize the pinning of a sample and we ascertain the spatially resolved energy landscape. To understand the mechanism of the pinning, we probe the strong skyrmion size and shape dependence of the pinning. Magnetic microscopy imaging demonstrates that in contrast to findings in previous investigation…

We observed some well-established artificial intelligence engineering approaches, but practices and tools are still needed for the testing and monitoring of ML-enabled systems. Peer reviewed
Airy-function approach to binary black hole merger waveforms: The fold-caustic diffraction model
2022
From numerical simulations of the Einstein equations, and also from gravitational wave observations, the gravitational wave signal from a binary black hole merger is seen to be simple and to possess certain universal features. The simplicity is somewhat surprising given that non-linearities of general relativity are thought to play an important role at the merger. The universal features include an increasing amplitude as we approach the merger, where transition from an oscillatory to a damped regime occurs in a pattern apparently oblivious to the initial conditions. We propose an Airy-function pattern to model the binary black hole (BBH) merger waveform, focusing on accounting for its simpl…

Algunes reflexions a l’entorn de la relació entre traducció, recepció i hipertextualitat
2022
This paper analyses, based on Genette's theory of hypertextuality, the relationship between translation and reception and the rewrites that derive from it. Leaving aside translation as a serious transformation or transposition, it focuses, first, on exploring translation as the only possible mediation to ensure the reader's familiarity with the foreign hypotext transformed by the hypertext, from the translation of Mark Twain's El Diari d'Eva and the Catalan hypertexts. Secondly, it approaches reception as a hypertextual requirement with the study of Hi ha homes que ploren perquè el sol es pon, by Francesc Trabal, a parody of Faust which, to a large extent, is explained as a playful reaction…
Influence of Environmental Pollution and Living Conditions on Parasite Transmission among Indigenous Ecuadorians
2022
The purpose of this study was to evaluate the influence of environmental pollution and the living conditions of indigenous Ecuadorians on the transmission of enteroparasites in an Andean agricultural area located at high altitude. Environmental pollution was recorded after observation in each community. The parasites were identified by microscopic sediment analysis using physiological saline solution from macerated arthropods, washed vegetables, and human stools, utilizing four coproparasitological techniques (direct examination, Kato–Katz, ether concentration, and Ziehl–Neelsen). The results show that the inadequate disposal of human and animal excreta that contaminate soil and…
Influenza Vaccination and COVID-19 Outcomes in People Older than 50 Years: Data from the Observational Longitudinal SHARE Study
2022
Existing literature on the association between influenza vaccination and COVID-19 infection/outcomes is conflicting. Therefore, we aimed to investigate the association between influenza vaccination and COVID-19 outcomes in a large cohort of adults who participated in the SHARE (Survey of Health, Ageing, and Retirement in Europe). Information regarding influenza vaccination in the previous year, and medical and demographic characteristics, were self-reported. Positivity for COVID-19, symptomatology, and hospitalization were also ascertained using self-reported information. An adjusted logistic regression analysis (including 15 baseline factors or propensity score) was used to assess the asso…
Growth and development of succulent mixtures for extensive green roofs in a Mediterranean climate.
2022
Green roof systems, aimed at reducing anthropic impact on the environment, are considered environmental mitigation technologies and adopted by many countries across the world to strengthen urban ecosystem services. This study evaluates two mixtures of succulent: one of Crassulaceae and the other of Aizoaceae, used in the creation of a continuous and homogenous plant groundcover in Mediterranean environments. To assess the species mixtures, the parameters plant height, growth index, cover percentage and flowering were observed. Hydrological observations were also carried out to evaluate the rainfall retained by the test system in any given month. All data were subjected to analysis of varian…

Production of acidic and alkaline solutions via Electrodialysis with bipolar membranes from synthetic and real brines from saltworks
2022
1. Introduction In recent decades, there has been a great deal of interest at both the industrial and academic levels in identifying unconventional sources for chemical production and raw material recovery. In this context, brine disposal, which was previously addressed as a priority to reduce environmental problems, is now seen as an opportunity to apply new or existing technologies in circular processes that allow for the valorization of previously considered waste solutions [1]. In this regard, Electrodialysis with bipolar membranes (EDBM) can be used to produce acidic and alkaline solutions from salty solutions. EDBM is an electro-membrane process distinguished by the alternated positio…

Inclusive, prompt and non-prompt J/ψ production at midrapidity in p-Pb collisions at √sNN = 5.02 TeV
2022
A measurement of inclusive, prompt, and non-prompt J/ψ production in p-Pb collisions at a nucleon-nucleon centre-of-mass energy √sNN = 5.02 TeV is presented. The inclusive J/ψ mesons are reconstructed in the dielectron decay channel at midrapidity down to a transverse momentum pT = 0. The inclusive J/ψ nuclear modification factor RpPb is calculated by comparing the new results in p-Pb collisions to a recently measured proton-proton reference at the same centre-of-mass energy. Non-prompt J/ψ mesons, which originate from the decay of beauty hadrons, are separated from promptly produced J/ψ on a statistical basis for pT larger than 1.0 GeV/c. These results are based on the data sample collecte…
