The Royal College of Surgeons of England Damage Control Orthopaedic Trauma Skills course (DCOTS): resuscitative knowledge and confidence in surgical skills are reliably maintained at six months post course
Authors: Parker P , Bodger O , Pallister I 
Published: June 2023

Introduction Since 2012, the Damage Control Orthopaedic Trauma Skills course (DCOTS) has trained more than 250 surgeons in the principles and practice of damage control orthopaedics and early appropriate care. This Royal College of Surgeons of England (RCS England) course takes place at the RCS England Partner cadaver laboratory at Brighton and Sussex Medical School. Trauma is a leading cause of morbidity and mortality in the UK, and the course has tried to pass on the lessons of war and conflict from its military faculty and hard-won lessons of “developed world” trauma from its experienced civilian faculty. Methods Participating surgeons were invited to score their self-reported confidence before attending the DCOTS course, immediately afterwards and again 6 months later. A modified four-point Likert scale was used, with responses from 1 = No Confidence to 4 = Very Confident. Damage control resuscitation principles with damage control surgery showed the greatest retained increase at 6 months – 100% – which is extremely satisfying. Results Self-reported confidence in pelvic external fixation was initially 93% dropping to 85%, which is also considered good to excellent. For pelvic packing, confidence was 90% at the end of the course, up from 19% precourse. This dropped to 62%, which was still considered good but low for the high standards of the course. This may relate to UK trainees’ lack of familiarity with the concept. Conclusions Three of the main skills taught on the DCOTS are effectively retained at 6 months post course.

Published: June 2023

Abstract
Low-energy ion detection in space is one of the most important interests of space exploration. An accurate calibration of this type of instrument is necessary to ensure the effectiveness and scientificness of the obtained data. And the ion source is the most critical equipment in a calibration facility. In this study, an ion beam system based on Kaufman ion source is designed, which can meet the ground calibration of space low-energy ion detection instrument in the low-energy range of 100–1,000 eV. The experimental research shows that when the beam intensity of the ion source is about 100 mA, the Faraday Cup collects about 1 mA of current, and the generated ion beam fluctuates less than 5% within 60 min, which can meet the ground calibration requirements of space low-energy ion detection instruments.
Language change and the actuation problem: grammaticalization in Vedic Sanskrit
Authors: Keydana Götz 
Published: June 2023

AbstractOne of the structures denoting the future in Sanskrit is the so-called-tā́-future, based on an agent noun and a present tense copula. Typologically, this grammaticalization path is unique. In this paper, this astonishing fact is tied to another unique feature of hysterotone-tŕ̥-nouns, their situative semantics, which forces a presupposition relating the event depicted by the noun to another event taken from the context. In ambiguous contexts, this relation could be (re-)interpreted by hearers as one between the event and the speech act itself. The grammaticalization, then, is hearer-based and triggered by semantic reanalysis. The process is essentially identical to phonemicization. The scenario developed in this paper thus further strengthens the position that grammaticalization is ontologically not distinct from other types of language change based on speaker–hearer interaction.
Walking Through Everyday Life: Tensions and Disruptions within the Ordinary
Authors: Conceição Nélio 
Published: June 2023

Abstract
Bringing together a genealogy of authors, concepts, and aesthetic case studies, this article aims to contribute to the discussion on ordinary aesthetics by focusing on the tensions that are intrinsic to walking as a fundamental embodied action in everyday urban life. These tensions concern the movement of walking itself and its relation to one’s surroundings, but it also concerns a certain complementarity between home (familiarity) and wandering. Experiencing space and thresholds that disrupt one’s relationship with home and the everyday can be understood as part of a modern “anti-home” tendency that lies at the core of several artistic and aesthetic practices. On the other hand, the study of walking and its relationship with the ordinary has also been enhanced and complexified by the mediation of images and technologies of reproduction. Approaching the paradoxes and ambiguities of everydayness from the perspective of walking allows us to better understand the ordinary as an in-between concept composed of evidence and mystery, familiarity and strangeness. Walking itself, as an ordinary element of life, is an unstable stabilisation, an unconsciousness that may become awareness, an immersive action that knows interruptions, a way of repeating paths that can also lead to detours and discoveries.
Investigation of cross-sensitivities of the potential drop method for structural health monitoring of civil structures
Authors: Schneegans Erik , Hug Joachim , Rembe Christian 
Published: June 2023

Abstract
Currently, structural health monitoring (SHM) systems are not in widespread use for monitoring civil structures because of low defect sensitivity and high cross-sensitivities of most SHM techniques available. The potential drop method (PDM), commonly used in material testing, is a possible method for SHM of large metallic civil structures combining high defect sensitivity and high area monitoring capability. The current state of the art lacks experimental evidence of the applicability to large specimens under the demanding operating conditions of SHM. Here, we investigated the PDM as an SHM system experimentally by analyzing the cross-sensitivity to temperature changes and performed a temperature compensation. We present an optimized method for suppressing the unwanted influence of mechanical loads and increasing the defect sensitivity. The temperature influence was separated from the defect-induced impedance change and effectively suppressed by compensation. Thus, cross-sensitivity does not limit PDM in SHM for large metallic civil structures with temperature compensation. PDM is a promising technique for SHM which could facilitate the widespread use of SHM of conductive civil structures.
Absence of a molecular circadian clock in the preimplantation embryo is a conserved characteristic in the mammal

Published: June 2023

In brief
It is not known when a functional circadian clock is established in the developing embryo. Lack of expression of key genes involved in the clock mechanism is indicative that a functional circadian clock mechanism is absent in the mammalian preimplantation embryo through the blastocyst stage of development.

Abstract
An embryonic circadian clock could conceivably organize cellular and developmental events temporally and in synchrony with other circadian rhythms in the mother. The hypothesis that a functional molecular clock exists in the preimplantation bovine, pig, human, and mouse embryo was tested by using publicly available RNAseq datasets to examine developmental changes in expression of the core genes responsible for the circadian clock – CLOCK, ARNTL, PER1, PER2, CRY1, and CRY2. In general, the transcript abundance of each gene decreased as development advanced to the blastocyst stage. The most notable exception was for CRY2, where transcript abundance was low and constant from the two-cell or four-cell to the blastocyst stage. Developmental patterns were generally the same for all species although there were some species-specific patterns such as an absence of PER1 expression in the pig, an increase in ARNTL expression at the four-cell stage in human, and an increase in expression of Clock and Per1 from the zygote to two-cell stage in the mouse. Analysis of intronic reads (indicative of embryonic transcription) for bovine embryos indicated an absence of embryonic transcription. Immunoreactive CRY1 was not detected in the bovine blastocyst. Results indicate that the preimplantation mammalian embryo lacks a functional intrinsic clock although specific components of the clock mechanism could conceivably play a role in other functions in the embryo.
Designing formulations of bio-based, multicomponent epoxy resin systems via machine learning
Authors: Albuquerque Rodrigo Q. , Rothenhäusler Florian , Ruckdäschel Holger 
Published: June 2023

AbstractPetroleum-based epoxy resins are commonly used as a matrix in fiber-reinforced polymer composites. Bio-based epoxy resin systems could be a more environmentally friendly alternative to conventional epoxy resins. In this work, novel formulations of multicomponent, amino acid-based resin systems exhibiting high or low glass-transition temperatures ($$T_{{\text{g}}}$$Tg) were designed via Bayesian optimization and active learning techniques. After only five high-$$T_{{\text{g}}}$$Tgexperiments, thermosets with$$T_{{\text{g}}}$$Tgalready higher than those of the individual components were obtained, pointing out the existence of synergistic effects among the amino acids used and confirming the efficiency of the theoretical design. Linear and nonlinear machine learning (ML) models successfully predicted$$T_{{\text{g}}}$$Tgwith a mean absolute error of 3.98$$^{\circ }{\text{C}}$$∘Cand$$R^2$$R2score of 0.91. A price reduction of up to 13.7% was achieved while maintaining the$$T_{{\text{g}}}$$Tgof 130$$^{\circ }{\text{C}}$$∘Cusing an optimized formulation. The LASSO model provided information about the dependence of$$T_{{\text{g}}}$$Tgon the number of active hydrogen atoms and aromaticity. This study highlights the importance of Bayesian optimization and ML to achieve a more sustainable development of epoxy resin materials.Impact statementThis article shows how the sustainability of epoxy resin systems (ERSs) can be significantly improved by combining experimental and theoretical strategies. First, amino acids are used as curing agents in multicomponent formulations to produce bio-based ERSs. Second, the number of trial-and-error experiments required to obtain formulations with high or low glass-transition temperatures (Tg) is greatly reduced using machine learning (ML) strategies to design all experiments. Not only is it shown howTgcan be maximized in only five new theoretically designed formulations, but the economic advantages of the proposed approach are also discussed. The trends betweenTgand the type of optimized biocomponents are discussed based on the unambiguous interpretation of the best-trained ML model. The results presented in this study pave the way for the theoretical design of more sustainable polymeric materials.Graphical abstract
El historiador es criatura de civilizaciones que se desintegran: una plática diacrónica entre Ernesto Volkening y Nicolás Gómez Dávila
Authors: Gómez-Arbeláez José Miguel 
Published: June 2023

En este texto se examina el fructífero diálogo sobre la naturaleza de la historia consignado en el Diario de lectura que lleva Ernesto Volkening (1908-1983) sobre los Escolios de Nicolás Gómez Dávila (1913-1994). Entre escolios y comentarios se hila una concepción de la historia que, a pesar de ser fragmentaria, guarda una auspiciosa coherencia. El historiador, el hecho histórico y el individuo son los conceptos centrales respecto a los cuales se compone el pensamiento histórico. Sin embargo, ese pensamiento solo se vislumbra en el diálogo entablado, pues los escolios se ven iluminados por los comentarios de Volkening: quien ante la etérea soledad del escolio suele proponer un acontecimiento histórico o un historiador como ejemplo.
Crearse a sí mismo en la escritura. Aspectos filosóficos de la obra ensayística de Hernando Téllez
Authors: Serrano López Federico Guillermo 
Published: June 2023

El presente artículo pone en alto los aspectos filosóficos de la investigación sobre sí mismo que realizó el escritor Hernando Téllez (1908-1966) en su obra ensayística. Esto permite señalar la condición híbrida y abierta del género ensayístico, la cual hace posible situar la reflexión de Téllez en un espacio indiscernible entre la literatura y la filosofía con un mutuo enriquecimiento de estas dos formas de pensamiento. A partir de lo anterior, se concluye que es necesario reinterpretar el período previo a la profesionalización de la filosofía en Colombia, ya no solo como un lapso de tránsito a la modernización, sino como un momento de la reflexión literaria y filosófica con sus propias gramáticas de creación, relacionamiento y divulgación del pensamiento.

Authors: Vieira Laissa Gama , Meirelles Salotti Bruno , Sarquis Raquel Wille 
Published: June 2023

Objetivo: Este trabalho tem como objetivo analisar a qualidade das notas explicativas acerca da implementação da IFRS 15 no Brasil.
Método: Foram analisadas 429 empresas do mercado brasileiro, comparando as notas explicativas relacionadas ao efeito da IFRS 15. Houve uma classificação desses efeitos quanto aos impactos registrados em notas explicativas, ou falta deles, no ano de 2017 e comparativamente, em 2018, se esses foram maiores ou menores que os estimados ou ainda, se não foram relatados. Também foi construído um índice para medir a Qualidade das Notas Explicativas (IQNE).
Resultados: Verificou-se que mais da metade das empresas apenas reclassificaram contas para melhor apresentação, aumentaram a divulgação em notas ou não tiveram nenhum impacto. Constatou-se, portanto, que a nova norma não trouxe mudanças significativas que causassem tanto impacto, mas ainda assim viabilizou uma maior utilidade e relevância nas informações financeiras prestadas pelas empresas a seus credores e investidores, principalmente em setores como utilidade pública, comunicação e construção civil.
Contribuições: É relevante ao discutir como as empresas lidam com a adoção de uma nova norma no que tange à sua preparação prévia e à análise dos efeitos efetivamente ocorridos. Também contribui para o Post-Implementation Review (PIR) da IFRS 15.

Published: June 2023

Background: Diabetes mellitus (DM) is a chronic metabolic disorder that can lead to multiple long-term complications in the human body including erectile dysfunction (ED). ED is a condition that commonly affects men and may reduce their quality of life. However, ED amongst men with type 2 DM (T2DM) has rarely been assessed and addressed by nurses who have an essential role in providing holistic patient care.Objective: This study aimed to describe ED among men with T2DM based on their demographic characteristics and health profiles.Methods: This was a descriptive study with a cross-sectional approach of 32 male respondents who were selected through convenience sampling in the outpatient department of PKU Muhammadiyah Hospital Yogyakarta, Indonesia. The data was collected by using the erectile function’s domain of Indonesian version of International Index of Erectile Function (IIEF). Descriptive statistics were used to present this study’s findings.Results: The results showed that 62.5% of the participants had uncontrolled blood glucose levels with an average random blood glucose of 207.75 ± 77.21 mg/dl. Only four respondents (12.5%) had received sexual counselling. Twenty-nine respondents (90,6%) had ED which were categorized into mild (17.2%), mild to moderate (6.9%), moderate (24.1%) and severe (51.7%).Conclusion: ED levels varied across age, duration of T2DM, random blood glucose levels, previous history of smoking, current smoking status, sexual counselling experience, complications, and occupation levels. Severe ED was common amongst men with T2DM in this study. Nurses should assess patient’s sexual function regularly and identify the effects of ED in men with T2DM. Early detection of ED could allow nurses to plan adequate intervention and health education to provide better outcomes for men with T2DM.

Authors: Gorkhali Rajendra , Humagain Vaskar , C. Dirgha Raj R. , Marhattha Suman Babu , Bista Rishi 
Published: June 2023

Background: One of the substantial complications of total knee arthroplasty is major blood loss. Postoperative blood loss can range up to 2000 ml and 10-38% of patients may require blood transfusion. Among the sundry methods of preventing this prob, tranexamic acid, an anti-fibrinolytic, is one of the most effective options. It can be administered directly into the blood or injected locally. The purpose of this study was to compare the hemostatic effects of intraarticular versus intravenous administration of tranexamic acid in primary total knee arthroplasty.
Methods: A prospective comparative observational study was done from done September 2020 to February 2022 at Civil Service Hospital, Kathmandu. 64 patients randomized into two groups: an intraarticular tranexamic acid group (31 patients who received 3.0 grams of intraarticular tranexamic acid) and intravenous tranexamic acid group (31 patients who received 15 mg/kg intravenous tranexamic acid in two instances). The primary measure was the amount of hemoglobin loss. Secondary outcomes included comparison of hemoglobin level pre- and post- operatively at first and fifth day, drain volume at 48 hours and amount of blood transfusion. There were no significant differences in demographics or preoperative laboratory values between the groups.
Results: The baseline data, preoperative hemoglobin, and tourniquet time were similar in both groups. Hemoglobin at first and fifth operative day and drain volume at 48 hours were measured in both categories. There was no significant difference in perioperative blood loss, drain volume, rates of allogeneic blood transfusion between the two groups. No any thromboembolic complications occurred.
Conclusions: Intra-articular administration of tranexamic acid was found to be as effective and safe as intra-venous administration in reducing blood loss in primary total knee arthroplasty.
