Pioneras en escena : el Pioneer Club y el teatro británico de la década de 1890
2021
espanolLas artes escenicas fueron un ingrediente esencial en la actividad de los clubes femeninos de Londres a partir de la decada de 1890, que contribuyo a la renovacion del teatro britanico del cambio de siglo. Sin embargo, su presencia en estos espacios ha sido sistematicamente olvidada por la historia teatral del periodo. El objetivo de este articulo es trazar un mapeo de su influencia desde una triple perspectiva: ludico-formativa; como promotor de dramaturgas con escasa visibilidad en los circulos mas comerciales, y de renovacion escenica. Para esta ultima, acudimos al estudio de caso del Pioneer Club que, como concluiremos, nutrio el discurso progresista de los ibsenitas y movimiento…
The Orange Peel: An Outstanding Source of Chemical Resources
2021
Citrus sinensis (L.) Osbeck is a very common cultivar belonging to the Rutaceae family. It is largely diffused in several areas of the world characterized by mild to warm climate conditions. Its abundant worldwide production (up to 107 Tons. per year) and consumption both as the edible part of the fruit and as several types of derivative products imply the production of a huge amount of waste, such as the fruit pomace. Several ways of recycling this material have been developed in recent years: employment as fertilizer, fodder ingredient, and even cloth material. However, the chemical added value of Citrus sinensis peel has been underestimated despite the diversified and significant content…
Russian School in the Socio-Political Space of Latvia (1991 – 2021)
2021
Russian-language teaching schools, or bilingual schools, are the most important institution for the reproduction of the ethno-cultural collective identity of the Russian and Russian-speaking population in modern Latvia. The present and future of these schools are included in a very complex legal and socio-political context. On the one hand, Latvian legislation proclaims the right of ethnic minorities to preserve their identity, on the other hand, the dominant political discourse is focused on reducing teaching in Russian in these schools to a minimum. The article shows that it is the political context constructed by the leading political parties, and not the rights guaranteed by the constit…
The role of ceus in the evaluation of thyroid cancer: from diagnosis to local staging
2021
Ultrasound often represents the first diagnostic step for thyroid nodule evaluation in clinical practice, but baseline US alone is not always effective enough to achieve thyroid nodule characterization. In the last decades new ultrasound techniques, such as CEUS, have been introduced to evaluate thyroid parenchyma as recommended by EFSUMB guidelines, for use in clinical research field, although its role is not yet clear. Several papers show the potential utility of CEUS in the differential diagnosis of benign and malignant thyroid nodules and in the analysis of lymph node involvement in neoplastic pathology. Therefore, we carried out an evaluation of the literature concerning the role of CE…
A deshora en la escuela
2021
El creciente cuerpo de evidencia en la literatura sobre cronobiología y cronomedicina cuestiona si la organización de los tiempos de aprendizaje escolar tiene en cuenta el tiempo biológico y, en particular, en relación con el tiempo para descansar y comer, y los ciclos de actividad académica alerta-fatiga. Tanto en los campos de los estudios de salud como de la educación, la preocupación es cada vez mayor por las consecuencias para la salud y el rendimiento académico de un desajuste permanente entre el reloj social y los relojes internos del estudiantado.

A New Routine for Analyzing Brief Symptom Inventory Profiles in Chronic Pain Patients to Evaluate Psychological Comorbidity
2021
Question: Comorbidity, i.e., additional psychological distress in patients already suffering from chronic somatic diseases (e.g., orthopedic conditions) is of growing importance. The quality of analyzing and interpreting the often used Brief Symptom Inventory (BSI) used with orthopedic patients should improve by employing a new “case definition” of four groups (instead of two) of differentially psychologically distressed patients instead of two groups as before.Methods: Four groups with the different psychological distress definitions of “no,” “mild,” “remarkable,” and “severe” were to be analyzed from a group of 639 orthopedic patients in inpatient rehabilitation clinics. The BSI is transf…

Improving the Performance of Steel Machining Processes through Cutting by Vibration Control
2021
Machining processes through cutting are accompanied by dynamic phenomena that influence the quality of the processed surfaces. Thus, this research aimed to design, make, and use a tool with optimal functional geometry, which allowed a reduction of the dynamic phenomena that occur in the cutting process. In order to carry out the research, the process of cutting by front turning with transversal advance was taken into account. Additionally, semi-finished products with a diameter of Ø = 150 mm made of C45 steel were chosen for processing (1.0503). The manufacturing processes were performed with the help of two tools: a cutting tool, the classic construction version, and another that was the i…

Antioxidant Bioactivity of Extracts from Beach Cast Leaves of Posidonia oceanica (L.) Delile
2021
The marine environment is a generous source of biologically active compounds useful for human health. In 50 years, about 25,000 bioactive marine compounds have been identified, with an increase of 5% per year. Peculiar feature of algae and plants is the production of secondary metabolites, such as polyphenols, synthesized as a form of adaptation to environmental stress. Posidonia oceanica is a Mediterranean endemic and dominant seagrass and represents a biologically, ecologically and geologically important marine ecosystem. Within this study, methanolic and ethanolic extracts were generated from fresh and dried Posidonia 
Tiempo y escuela. Aportación desde la cronobiología y cronopsicología a la Sociología de la Educación. Anotaciones para la reflexión
2021
La preocupación por una correcta organización de los horarios escolares se centra en el qué (curriculum), el cómo (metodología) y en el cuándo hay que enseñar, pero este cuando se centra en la mayoría de las veces en cómo distribuir las materias a lo largo de la jornada, o en el tipo de jornada escolar. La cronobiología y cronopsicología centran su mirada en la organización de la propia actividad del ser vivo, la persona, y aportan conocimientos sobre los momentos óptimos de determinadas actividades y la conveniencia de respetarlas dentro de unos márgenes adaptativos, como son la activación y el reposo /sueño, el ritmo atencional, la memoria, y la actividad intelectual en su conjunto, mostr…
Mandible histology in Metoposaurus krasiejowensis (Temnospondyli, Stereospondyli) from the Upper Triassic of Poland
2021
Recent studies that have systematically augmented our knowledge of dermal bones of the Late Triassic temnospondyl amphibian Metoposaurus krasiejowensis have mostly focused on shoulder girdle elements and the skull. So far, histological data on the mandible are still scant. For the present study, two mandibles have been examined, using 50 standard thin sections. Dermal bones of the mandible reveal a uniform diploë structure, with the external cortex consisting of moderately vascularised, parallel-fibred bone, as well as a distinct alternation of thick zones and thinner annuli. Dense bundles of well-mineralised Sharpey’s fibres are seen in the external cortex over the entire length of the man…
Jet fragmentation transverse momentum distributions in pp and p-Pb collisions at √s, √sNN = 5.02 TeV
2021
Jet fragmentation transverse momentum (jT) distributions are measured in proton-proton (pp) and proton-lead (p-Pb) collisions at √sNN = 5.02 TeV with the ALICE experiment at the LHC. Jets are reconstructed with the ALICE tracking detectors and electromagnetic calorimeter using the anti-kT algorithm with resolution parameter R = 0.4 in the pseudorapidity range |η| < 0.25. The jT values are calculated for charged particles inside a fixed cone with a radius R = 0.4 around the reconstructed jet axis. The measured jT distributions are compared with a variety of parton-shower models. Herwig and Pythia 8 based models describe the data well for the higher jT region, while they underestimate the low…
A Velocity Estimation Technique for a Monocular Camera Using mmWave FMCW Radars
2021
Perception in terms of object detection, classification, and dynamic estimation (position and velocity) are fundamental functionalities that autonomous agents (unmanned ground vehicles, unmanned aerial vehicles, or robots) have to navigate safely and autonomously. To date, various sensors have been used individually or in combination to achieve this goal. In this paper, we present a novel method for leveraging millimeter wave radar’s (mmW radar’s) ability to accurately measure position and velocity in order to improve and optimize velocity estimation using a monocular camera (using optical flow) and machine learning techniques. The proposed method eliminates ambiguity in optical flow veloci…
Pathways From Narcissism to Leadership Emergence in Social Groups
2021
Narcissists successfully emerge as leaders. However, the processes by which this occurs are mostly unknown. Following a dual-pathway approach and differentiating between agentic (narcissistic admiration) and antagonistic (narcissistic rivalry) narcissism, we investigated the behavioral processes underlying narcissists’ leadership emergence in social groups. We applied data from a multimethodological laboratory study ( N = 311) comprising three groups of variables: personality traits, expressed interaction behaviors, and interpersonal perceptions. Prior to the laboratory sessions, participants provided self-reported answers to various narcissism measures. Interpersonal perceptions were obta…
Digital skills and application use among Finnish home care workers in the eldercare sector
2021
This chapter explores the role digital skills, interest in technology, and social support have in home care workers’ use of digital applications at work.

Including gender perspective in a Computer Engineering Degree
2021
The 2030 Agenda for Sustainable Development defines the need to guarantee an inclusive and equitable quality education for all people. This means that education systems should introduce the gender debate in different areas of education, from teacher training to the definition of subject knowledge, with the purpose of changing traditional roles and gender stereotypes. Incorporating the gender perspective in teaching involves reflecting on the different elements that make up the teaching-learning process from the point of view of the sex and gender variables. But, in addition, it means understanding in what context that teaching is taught and what competences must be offered to students. This…

The impact of del Nido cardioplegia solution on blood morphology parameters
2021
Background: Crystalloid cardioplegic solutions are believed to reduce hemoglobin significantly and increase the transfusion rate. However, recent reports indicate that the del Nido cardioplegia may preserve blood morphology parameters. Methods: In “The del Nido versus cold blood cardioplegia in aortic valve Replacement” trial patients undergoing aortic valve replacement were randomized into the del Nido (DN) or cold blood cardioplegia (CB) group. For the subanalysis, patients who underwent blood transfusions were excluded from the study. Red blood cell (RBC) count, hemoglobin, white blood cell (WBC) count and platelet (PLT) count were measured before the surgery, 24-, 48-, and 96 hours post…
Mechanisms of irreversible aquaporin-10 inhibition by organogold compounds studied by combined biophysical methods and atomistic simulations
2021
Abstract The inhibition of glycerol permeation via human aquaporin-10 (hAQP10) by organometallic gold complexes has been studied by stopped-flow fluorescence spectroscopy, and its mechanism has been described using molecular modelling and atomistic simulations. The most effective hAQP10 inhibitors are cyclometalated Au(III) C^N compounds known to efficiently react with cysteine residues leading to the formation of irreversible C–S bonds. Functional assays also demonstrate the irreversibility of the binding to hAQP10 by the organometallic complexes. The obtained computational results by metadynamics show that the local arylation of Cys209 in hAQP10 by one of the gold inhibitors is mapped int…

A machine learning algorithm for direct detection of axion-like particle domain walls
2021
The Global Network of Optical Magnetometers for Exotic physics searches (GNOME) conducts an experimental search for certain forms of dark matter based on their spatiotemporal signatures imprinted on a global array of synchronized atomic magnetometers. The experiment described here looks for a gradient coupling of axion-like particles (ALPs) with proton spins as a signature of locally dense dark matter objects such as domain walls. In this work, stochastic optimization with machine learning is proposed for use in a search for ALP domain walls based on GNOME data. The validity and reliability of this method were verified using binary classification. The projected sensitivity of this new analy…
