Authors: Lian Jinming , Xu Lei , Wu Donggao , Wang Zhenqing
Published: December 2023

The introduction of hierarchical structure in cell materials can further improve their energy absorption effect, and negative Poisson's ratio materials have excellent energy absorption capacity and special deformation mode. In this paper, augmented double arrow honeycomb structures is introduced into the re-entrant honeycomb with negative Poisson's ratio as a substructure (RHA) to improve the mechanical properties of the first-order re-entrant honeycomb and enhance the energy absorption effect of the structure. The analytical formula of the collapse stress of honeycomb under quasi-static compression was derived by the two-scale method. The failure stress of RHA under different relative densities and impact velocities is discussed, and the analytical formula of RHA stress in dynamic crushing is derived by combining momentum conservation. Due to the special substructure, the secondary honeycomb discussed in this paper has two plateau periods. In this paper, the second plateau stress of the honeycomb structure is calculated innovatively. The numerical simulation results show that the collapse stress of RHA in the first plateau period is similar to that of the first-order re-entrant honeycomb, and the collapse stress in the second plateau period is increased by 332%. The research in this paper shows that the honeycomb with the second plateau period has a better energy absorption effect, which is an effective strategy for improving the energy absorption effect of the honeycomb. It can be further explored to improve the impact resistance of the honeycomb.

Published: December 2023

Today's electrical power system is a complicated network that is expanding rapidly. The power transmission lines are more heavily loaded than ever before, which causes a host of problems like increased power losses, unstable voltage, and line overloads. Real and reactive power can be optimized by placing energy resources at appropriate locations. Congested networks benefit from this to reduce losses and enhance voltage profiles. Hence, the optimal power flow problem (OPF) is crucial for power system planning. As a result, electricity system operators can meet electricity demands efficiently and ensure the reliability of the power systems. The classical OPF problem ignores network emissions when dealing with thermal generators with limited fuel. Renewable energy sources are becoming more popular due to their sustainability, abundance, and environmental benefits. This paper examines modified IEEE-30 bus and IEEE-118 bus systems as case studies. Integrating renewable energy sources into the grid can negatively affect its performance without adequate planning. In this study, control variables were optimized to minimize fuel cost, real power losses, emission cost, and voltage deviation. It also met operating constraints, with and without renewable energy. This solution can be further enhanced by the placement of distributed generators (DGs). A modified Artificial Hummingbird Algorithm (mAHA) is presented here as an innovative and improved optimizer. In mAHA, local escape operator (LEO) and opposition-based learning (OBL) are integrated into the basic Artificial Hummingbird Algorithm (AHA). An improved version of AHA, mAHA, seeks to improve search efficiency and overcome limitations. With the CEC'2020 test suite, the mAHA has been compared to several other meta-heuristics for addressing global optimization challenges. To test the algorithm's feasibility, standard and modified test systems were used to solve the OPF problem. To assess the effectiveness of mAHA, the results were compared to those of seven other global optimization algorithms. According to simulation results, the proposed algorithm minimized the cost function and provided convergent solutions.

Published: December 2023

The study focuses on the behavior of an electrically conducting non-Newtonian fluid with couple stress properties, using water-based bionanofluid. The fluid is analyzed as it flows across a porous stretching/shrinking sheet within its own plane. This Study also explores the Bejan Number and Entropy Generation. To facilitate this investigation, the governing nonlinear partial differential equations undergo a transformation, wherein they are converted into nonlinear ordinary differential equations through a suitable similarity transformation. An ideal strategy has been employed to achieve the desired results from the modeled challenge. The Homotopy Analysis Method is applied to determine the solution of the system of differential equations. The convergence of the applied method and their comparison with the numerical method are described through graphs and tables. The main features of the different profiles are briefly described. Graphs are used to analyze the impact of the Bejan number, concentration, temperature, velocity profile, and entropy production rate. Tables present the characteristics of skin friction, Nusselt, and Sherwood numbers for various limitations. The stretching and ambient fluid velocities should fluctuate linearly as the distance from the stagnation point increases. A rise in the magnetic and porosity parameters is accompanied by an increase in the velocity profile. While the velocity profile falls off as a Couple of fluid parameters are increased. The phenomenon of temperature boost is observed to be positively correlated with the increase in Brownian motion parameter while exhibiting no significant dependence on other parameters such as Brinkman number, Prandtl number Lewis number and Thermophoresis parameter. Entropy generation increases with the Brinkman number while decreasing with the radiation parameter and diffusion parameter as is plainly demonstrated.

Published: December 2023

Life expectancy is likely to be substantially reduced in patients undergoing chronic hemodialysis (CHD). However, machine learning (ML) may predict the risk factors of mortality in patients with CHD by analyzing the serum laboratory data from regular dialysis routine. This study aimed to establish the mortality prediction model of CHD patients by adopting two-stage ML algorithm-based prediction scheme, combined with importance of risk factors identified by different ML methods. This is a retrospective, observational cohort study. We included 800 patients undergoing CHD between December 2006 and December 2012 in Shin-Kong Wu Ho-Su Memorial Hospital. This study analyzed laboratory data including 44 indicators. We used five ML methods, namely, logistic regression (LGR), decision tree (DT), random forest (RF), gradient boosting (GB), and eXtreme gradient boosting (XGB), to develop a two-stage ML algorithm-based prediction scheme and evaluate the important factors that predict CHD mortality. LGR served as a bench method. Regarding the validation and testing datasets from 1- and 3-year mortality prediction model, the RF had better accuracy and area-under-curve results among the five different ML methods. The stepwise RF model, which incorporates the most important factors of CHD mortality risk based on the average rank from DT, RF, GB, and XGB, exhibited superior predictive performance compared to LGR in predicting mortality among CHD patients over both 1-year and 3-year periods. We had developed a two-stage ML algorithm-based prediction scheme by implementing the stepwise RF that demonstrated satisfactory performance in predicting mortality in patients with CHD over 1- and 3-year periods. The findings of this study can offer valuable information to nephrologists, enhancing patient-centered decision-making and increasing awareness about risky laboratory data, particularly for patients with a high short-term mortality risk.
Partisanship and energy efficiency program participation in the USA
Authors: Mayer Adam , Carter Ellison , Feinberg Elizabeth
Published: December 2023

Utilities and municipal governments often implement energy efficiency programs to encourage households to improve the energy efficiency of their residences through measures such as weatherizing their homes, installing insulation, replacing inefficient appliances, setting up solar panels, among others. However, these programs often meet with variable success, with some having relatively few participants despite the promise of cost-savings for homeowners. Even as municipal-scale, home energy efficiency programs have grown in popularity, political polarization has increased in the USA. We suggest that political partisanship is an under-studied but potentially important predictor of program participation and use two datasets from Fort Collins, CO to evaluate the relationship between partisanship and energy efficiency program participation Our results imply that partisanship has a modest effect on program participation—this effect is also not highly robust. These results are encouraging in that they imply that partisanship does not greatly affect household decision-making to engage in energy efficiency programs, but at a grid or regional scale partisanship may act as a small barrier to energy efficiency.

Published: December 2023

When teaching STEM courses, it is important to introduce state-of-the-art techniques. Students need to learn how to conduct experiments, analyse data and choose the most effective approaches to address meaningful situations. Here we present the assessment of the implementation of a structured inquiry-based activity aimed at teaching students about protein mass and size. This activity emerges as an intervention in our educational module, designed to create a cognitive conflict that effectively drives a conceptual change. To evaluate the efficacy of this module, we collected data on students’ perceived and actual knowledge through pre- and post-class surveys (n = 36 and 34, respectively, mean age 26 ± 2). Additionally, we evaluated lab reports using a detailed rubric. Results indicate that the practical innovation we propose is a challenging activity that promotes the accomplishment of our learning objectives. The activity led to improvements both in confidence and in actual mastery of theoretical concepts and techniques. After completing the activity, students were able to choose the most appropriate technique to solve specific problems. Furthermore, we found that the use of a structured questionnaire in lab reports helped students to accurately analyse and process experimental data. It also allows them to demonstrate understanding of technical limitations, while integrating the knowledge and skills acquired during the module. Overall, this activity provides notions that are conceivable and profitable, thus leading to successful conceptual changes.

Generalization in Aphasia Treatment: A Tutorial for Speech-Language Pathologists
Authors: Mayer Jamie F. , Madden Elizabeth B. , Mozeiko Jennifer , Murray Laura L. , Patterson Janet P. , Purdy Mary , Sandberg Chaleece W. , Wallace Sarah E.
Published: December 2023

Purpose:

Generalization has been defined and instantiated in a variety of ways over the last half-century, and this lack of consistency has created challenges for speech-language pathologists to plan for, implement, and measure generalization in aphasia treatment protocols. This tutorial provides an overview of generalization with a focus on how it relates to aphasia intervention, including a synthesis of existing principles of generalization and examples of how these can be embedded in approaches to aphasia treatment in clinical and research settings.

Method:

Three articles collectively listing 20 principles of generalization formed the foundation for this tutorial. The seminal work of Stokes and Baer (1977) focused attention on generalization in behavioral change following treatment. Two aphasia-specific resources identified principles of generalization in relation to aphasia treatment (Coppens & Patterson, 2018; Thompson, 1989). A selective literature review was conducted to identify evidence-based examples of each of these 20 principles from the extant literature.

Results:

Five principles of generalization were synthesized from the original list of 20. Each principle was supported by studies drawn from the aphasia treatment literature to exemplify its application.

Conclusions:

Generalization is an essential aspect of meaningful aphasia intervention. Successful generalization requires the same dedication to strategic planning and outcome measurement as the direct training aspect of intervention. Although not all people with aphasia are likely to benefit equally from each of the principles reviewed herein, our synthesis provides information to consider for maximizing generalization of aphasia treatment outcomes.

Non‐singular fixed‐time fuzzy adaptive control for nonlinear systems subject to actuator faults
Authors: Yu Dengxiu , Jia Zhanxiao , Chen Kang , Chen C. L. Philip
Published: December 2023

This paper proposes a non‐singular fixed‐time fault‐tolerant adaptive tracking control method for a kind of multi‐input and multi‐output nonlinear system, which is in form of non‐strict feedback and is subject to actuator faults. The major contribution, compared to other practical fixed‐time fault‐tolerant control methods, is that the fixed time can be calculated precisely. By applying fuzzy logic systems, the identification of unknown nonlinearities is achieved, and by the boundness of fuzzy basis functions, the algebraic loop problem is avoided. Based on the fixed‐time stability theory, the practical fixed‐time fault‐tolerant adaptive tracking control method is proposed with adaptive back‐stepping control technology, in which the control singular problem is overcome by applying the adding power integration method. By the Lyapunov function theory, the practical fixed‐time stability of the closed‐loop system is theoretically proved. And even in the case of unknown actuator faults, the tracking error of the controlled system for the given command signal can still converge to a small neighbourhood of zero within a fixed time, regardless of the system initial state. Finally, the proposed control method is successfully implemented on a multi‐motor control platform, proving its effectiveness, and multiple comparative simulations are carried out, demonstrating its superiority.
Proof‐of‐concept of a robotic‐driven photogrammetric scanner for intra‐operative knee cartilage repair

Published: December 2023

This work presents a proof‐of‐concept of a robotic‐driven intra‐operative scanner designed for knee cartilage lesion repair, part of a system for direct in vivo bioprinting. The proposed system is based on a photogrammetric pipeline, which reconstructs the cartilage and lesion surfaces from sets of photographs acquired by a robotic‐handled endoscope, and produces 3D grafts for further printing path planning. A validation on a synthetic phantom is presented, showing that, despite the cartilage smooth and featureless surface, the current prototype can accurately reconstruct osteochondral lesions and their surroundings with mean error values of 0.199 ± 0.096 mm but with noticeable concentration on areas with poor lighting or low photographic coverage. The system can also accurately generate grafts for bioprinting, although with a slight tendency to underestimate the actual lesion sizes, producing grafts with coverage errors of −12.2 ± 3.7, −7.9 ± 4.9, and −15.2 ± 3.4% for the medio‐lateral, antero‐posterior, and craneo‐caudal directions, respectively. Improvements in lighting and acquisition for enhancing reconstruction accuracy are planned as future work, as well as integration into a complete bioprinting pipeline and validation with ex vivo phantoms.
Analysis and stabilization for full harmonic compensation oscillation in SAPF system with source current direct control
Authors: Xie Yihan , Yi Hao , Zhuo Fang , Li Yuguo , Jiang Xin , Zhang Zhilong
Published: December 2023

Shunt active power filter (SAPF) has emerged as a promising solution for mitigating harmonic distortions. Due to the interaction between the current inner‐loop of SAPF, source impedance and non‐linear loads, harmonic oscillation issue arises and adversely affects the stability of the system, thus in turn exacerbating the harmonic distortion. However, previous studies paid less attention to the value of phase adjustment in improving the dynamic behaviour of the loop and thus stabilizing harmonic oscillation. Taking the dynamic characteristics between source impedance and non‐linear load into consideration, this paper models and analyzes the SAPF system with source current direct control to reveal the law of full harmonic compensation oscillation. Based on the analysis, an enhanced phase adjustment strategy using load current feedforward is proposed and designed to stabilize harmonic oscillation, while maintaining a favourable trade‐off between stability and harmonic compensation performance. The small‐signal model validated for stability analysis and the effectiveness of proposed stabilization strategy are verified by simulation and experiment.
Comparing trap and bait efficiency to record the great crested newts (Triturus cristatus)
Authors: Weber Lukáš , Botorová Martina , Rulík Martin
Published: December 2023

A crucial aspect of conservation management for endangered newt species is the establishment of a monitoring methodology and the evaluation of trap efficacy to ensure the accuracy of data collection. In this study, we assessed three funnel trap types (prism shape, umbrella shape, and Ortmann's trap) to capture great crested newts (Triturus cristatus). We also tested three baits (chicken liver, chemical lights in glow sticks, and control traps without bait) and determined the optimal trap control time within a 12 h period. Our findings showed that the umbrella shape trap was most effective, catching five times more newts than the Ortmann's and prism shape traps. Surprisingly, the commonly used prism shape trap performed poorly. Bait type did not significantly impact newt captures compared to control traps. During the 12 h experiment, newts spent the longest time in the chicken liver-baited Ortmann's trap (averaging 4.5 h), while the umbrella shape trap with chicken liver bait had the highest turnover of individuals. We observed no behavioural response from “trap-shy” individuals. This study emphasizes the importance of selecting appropriate traps, considering bait choice, and trap control time for effective monitoring of endangered newt populations.

Glucoraphanin in Keimsaaten

Published: December 2023

Als eine vielversprechende Quelle für bioaktive pflanzliche
Sekundärstoffe gelten Keimsprossen von Kreuzblütlerpflanzen
(Familie: Brassicaceae). Vor allem das in Brokkolisprossen in höheren
Konzentrationen vorkommende Glucoraphanin ist als bioaktiver Naturstoff von
besonderer Bedeutung. Glucoraphanin gehört zur Stoffklasse der
Glucosinolate (Senfölglucoside) und stellt das Prodrug von Sulforaphan
(1-Isothiocyanato-4-methylsulfinylbutan) dar, für das in zahlreichen
Studien antikarzinogene bzw. chemopräventive Effekte gezeigt werden
konnten. Zur Optimierung der täglichen Aufnahme von Glucosinolaten wird
die eigene Anzucht von Sprossen immer beliebter und eine Vielzahl
diesbezüglicher Brokkoli-Keimsaaten ist hierfür heute am Markt
verfügbar. In diesem Zusammenhang wurden in der vorliegenden Studie die
Glucosinolatmuster von 48 handelsüblichen Kreuzblütlersamen
untersucht, davon die Hälfte (24 Proben) mit der Deklaration
„Brokkoli“. In 15 der untersuchten Samenproben konnte
Glucoraphanin in deutlichen Mengen nachgewiesen werden. Lediglich 9 dieser
Samenmuster stammen laut Deklaration von Brokkoli, alle übrigen leiten
sich von anderen Varietäten der Stamm-Art Brassica oleracea ab.
Dies konnte analytisch eindeutig über die jeweiligen
Glucosinolat-Fingerprints mittels U(H)PLC und CE belegt werden. Die vorliegenden
Ergebnisse belegen, dass in vielen Fällen (15 von 24 Proben) trotz der
Deklaration „Brokkoli“ für das untersuchte Saatgut kein
für Brokkoli typisches Glucosinolatprofil nachweisbar ist und nur wenig
oder kein Glucoraphanin bestimmbar war. Dies wird als eine für
Verbraucher und Patienten unbefriedigende Situation bewertet.

Die Energiebilanz dient häufig zur Erklärung der Entstehung von

zu hohe Energieaufnahme und/oder einen Mangel an Bewegung
erklärt ist und somit eine Verringerung der Energiezufuhr oder eine
Erhöhung des Energieverbrauchs zu einem Energiedefizit und damit zu
einer Gewichtsabnahme führen. Dieses vereinfachende Paradigma
lässt jedoch die Regulation der Energiebilanz außer Acht und
verkennt damit die eigentlichen Ursachen und Therapieoptionen von
Übergewicht. Die Kontrolle der Energiebilanz ist ein dynamischer
Prozess, bei dem Veränderungen in einer Komponente der Energiebilanz
eine Kompensation in anderen Komponenten des Systems zur Folge haben.

Background Acquired hemophilia A (AHA) is a severe bleeding disorder caused by autoantibodies against coagulation factor VIII (FVIII). Standard treatment consists of bleeding control with bypassing agents and immunosuppressive therapy. Emicizumab is a bispecific antibody that mimics the function of activated FVIII irrespective of the presence of neutralizing antibodies. Recently, the GTH-AHA-EMI study demonstrated that emicizumab prevents bleeds and allows to postpone immunosuppression, which may influence future treatment strategies.

Aim To provide clinical practice recommendations on the use of emicizumab in AHA.

Methods A Delphi procedure was conducted among 33 experts from 16 German and Austrian hemophilia care centers. Statements were scored on a scale of 1 to 9, and agreement was defined as a score of ≥7. Consensus was defined as ≥75% agreement among participants, and strong consensus as ≥95% agreement.

Results Strong consensus was reached that emicizumab is effective for bleed prophylaxis and should be considered from the time of diagnosis (100% consensus). A fast-loading regimen of 6 mg/kg on day 1 and 3 mg/kg on day 2 should be used if rapid bleeding prophylaxis is required (94%). Maintenance doses of 1.5 mg/kg once weekly should be given (91%). Immunosuppression should be offered to patients on emicizumab if they are eligible based on physical status (97%). Emicizumab should be discontinued when remission of AHA is achieved (97%).

Conclusion These GTH consensus recommendations provide guidance to physicians on the use of emicizumab in AHA and follow the results of clinical trials that have shown emicizumab is effective in preventing bleeding in AHA.

Introducción y objetivos La fractura de escafoides es la más común dentro de las fracturas del carpo. El objetivo de nuestro trabajo es realizar un estudio analizando los resultados de las fracturas de escafoides en gente de edad avanzada.

Material y método Se realizó un estudio observacional retrospectivo recogiendo todas las fracturas de escafoides en pacientes de más de 65 años diagnosticadas del 2016 al 2020. Se recogieron las variables de edad, género, lateralidad, tipo de traumatismo, lugar del traumatismo, estabilidad de la fractura, clasificación según Herbert, trazo de fractura, presencia de lesiones asociadas, afectación de la mano dominante, tipo de tratamiento realizado y ausencia o no de consolidación.

Resultados Se registraron 24 pacientes con fractura de escafoides de más de 65 años. El 75% eran mujeres. La tasa de incidencia fue de 5,49 fracturas por cada 100.000 habitantes. Se halló una incidencia de pseudoartrosis del 8,3%. Se manejaron quirúrgicamente el 8,3% y fueron clasificadas como A2 el 37,5% de las fracturas.

Conclusión La tasa de incidencia de la fractura de escafoides en pacientes de más de 65 años hallada en nuestra área sanitaria es superior a la referida en los escasos estudios previos. Se observó prevalencia del género femenino y no se hallaron diferencias significativas para la consolidación de la fractura al comparar manejo conservador y quirúrgico.

Daytime air–water harvesting based on super hygroscopic porous gels with simultaneous adsorption–desorption

Published: December 2023

In recent years, solar-powered, passive adsorption-based air–water harvesting has shown tremendous potential in addressing freshwater shortages in arid regions. Although remarkable progress has been witnessed in unlocking the potential of new adsorbents in the laboratory, the productivity of freshwater is still limited by the slow adsorption kinetic, the large latent heat of water evaporation, and the efficiency of condensation. In this work, superhygroscopic porous gels consisting of titanium nitride, hydroxypropyl methylcellulose, and LiCl (THL) were developed and demonstrated to have a unique high water uptake of 1.18–6.43 gwatergsorbent−1 at 25 °C and 15%–90% relative humidity. To validate the feasibility of THL for moisture extraction, reasonable energy management of the water harvester was carried out, and the potential daytime outdoor water collection in summer and winter reached 3.82 and 2.98 lwater kgsorbent−1 day−1, respectively, at relative humidity of ∼60% and ∼30%. The implementation strategy proposed in this paper provides a reliable path for solar-driven AWH, confirming the adaptability and possibility of achieving high yield freshwater production in real scenarios of practical significance.
Solution of generalized fractional Jaulent–Miodek model with uncertain initial conditions

Published: December 2023

This paper analyses a coupled system of generalized coupled system of fractional Jaulent–Miodek equations, including uncertain initial conditions with fuzzy extension. In this regard, an extension of the homotopy with a generalized integral algorithm is adopted for a class of time-fractional fuzzy Jaulent–Miodek models by mixing the fuzzy q-homotopy analysis algorithm with a generalized integral transform and Caputo fractional derivative. The triangular fuzzy numbers (TFNs)are expressed in double parametric form using κ-cut and r-cut and utilized to explain the uncertainties arising in the initial conditions of highly nonlinear differential equations with generalized Hukuhara differentiability (gH-differentiability). The TFNs are controlled by the κ-cut and r-cut, and the variability of uncertainty is examined using a “triangular membership function” (TMF). The results are analyzed by finding the solutions for different spatial coordinate values of time with κ-cut and r-cut for both lower and upper bounds and validated through numerical and graphical representations in crisp cases. Finally, it can be seen that the uncertain probability density function rapidly decreases at the left and right edges when the fractional order is increased, and it is observed that the obtained solutions are more accurate than the existing results through the Hermite wavelet method in the literature.
Tunable infrared surface phonon–plasmon coupling in graphene-integrated polar semiconductor heterostructure

Published: December 2023

Within Reststrahlen bands of polar semiconductors, surface phonon–plasmon coupling is of great interest in infrared nanophotonics. Here, we demonstrate an active long-wavelength infrared device of graphene integrated with an AlN/SiC polar heterostructure. As a low-loss dielectric design, the subwavelength structure device takes advantage of interfacial photogating effect on electrostatic doping of the graphene and the interfaced SiC, and the tunable spectral behavior is originated from the hybridization of the doping-dependent surface phonon–plasmon resonances. This finding provides a steady-state manipulating method to the surface modes for the low-loss nanophotonic devices on SiC platform, and the graphene Fermi level tunable to cross the Dirac point in a steady response even makes the intrinsic graphene photodetectors feasible.

Sonochemical synthesis of nanophotocatalysts to produce functionalized fabrics is gaining significant attention worldwide. This study deals with coating sonochemically synthesized TiO2 and TiO2/BiOBr photocatalysts on pre-coating plasma functionalized cotton fabric. The photocatalytic activity of pristine, plasma-functionalized, and photocatalyst-coated fabrics was checked by degrading methyl red, Rhodamine B, and methyl orange under sunlight irradiation. The surface morphology, optical properties, structure, and purity of the coating material were elaborated using UV-visible spectroscopy, electrical resistivity measurements, x-ray diffraction measurements, inductively coupled plasma atomic emission spectroscopy analysis, scanning electron microscopy, Fourier transform infrared spectroscopy, and photoluminescence spectroscopy. The nanoparticle-coated fabrics significantly reduced the photoluminescence intensity compared to plasma-functionalized fabrics. The TiO2/BiOBr decorated fabric had significantly higher photocatalytic efficiency than all other fabric samples. This photocatalyst showed 84% efficiency against Rhodamine B, 58% against methyl orange, and 55% against methyl red. The-self-cleaning UV protection applications of these photocatalyst-decorated fabrics are suggested in this study.
Das Urbild der Menschheit de Krause en español
Authors: Schäpers Andrea
Published: December 2023

«El comienzo de la nueva cultura española es el krausismo y el comienzo del krausismo español fue una traducción».
Así hablaba Miguel Ángel Vega en 2001 al identificar la obra cumbre del krausismo en España: un texto titulado El Ideal de
la Humanidad para la vida, traducido y adaptado del alemán al castellano en 1860 por Julián Sanz del Río, y que sentó
las bases de una ideología moderna y reformadora. Sin embargo, el libro original del filósofo Karl Christian Friedrich Krause,
Das Urbild der Menschheit, que se había considerado la fuente original de Sanz del Río, nunca ha sido
traducido al español. Sanz del Río utilizó otro texto de la misma época de Krause, sin mencionar su fuente original, como pudo
demostrar en 1988 Enrique Ureña, prestigioso investigador en Liberalismo, Krausismo y Masonería. Considerando la importancia del
texto para el conjunto de la obra de Krause, y posiblemente más aún para el krausismo español, un grupo de investigadores de la
Universidad Pontificia Comillas se ha propuesto ofrecer la traducción de este texto original que pudo leer en alemán la primera
generación de krausistas españoles. En este trabajo, la traductora reflexiona sobre la tarea de traducir esta importante obra
krausista y aporta ejemplos para ilustrar su complejidad.
