Lack of sanitation is the underlying cause of many diarrheal infections and associated deaths. Improving sanitation through the set-up of ecological sanitation dry toilets, followed by the thermophilic composting of human excreta, could offer a solution. In addition, treating the excreta via thermophilic composting allows us to recycle the nutrients to be used as fertilizer for agriculture. However, for this purpose, the compost should be free of pathogens. We conducted a thermophilic composting trial over 204 to 256 days with human excreta, along with vegetable scraps and teff straw, with and without biochar. A sawdust–cattle manure mixture with the same supplements served as a control treatment. To evaluate the hygienic quality of the mature compost, the bacterial indicators Escherichia coli and Salmonella were assessed using the cultivation-based most probable number method. In addition, Ascaris lumbricoides eggs were quantified through light microscopy. The amount of detected E. coli was below the thresholds of German and European regulations for organic fertilizer. Salmonella and Ascaris eggs were not detected. No significant differences between the treatments were observed. Thus, the composting process was efficient in decreasing the number of potential human pathogens. The mature compost fulfilled the legal regulations on organic fertilizer regarding potential human pathogens.

Alzheimer’s disease (AD), the most prevalent neurodegenerative disease, is characterized by progressive and irreversible impairment of cognitive functions. However, its etiology is poorly understood, and therapeutic interventions are limited. Our preliminary study revealed that wasp venom (WV) from Vespa velutina nigrithorax can prevent lipopolysaccharide-induced inflammatory signaling, which is strongly implicated in AD pathogenesis. Therefore, we examined whether WV administration can ameliorate major AD phenotypes in the 5xFAD transgenic mouse model. Adult 5xFAD transgenic mice (6.5 months of age) were treated with WV by intraperitoneal injection at 250 or 400 μg/kg body weight once weekly for 14 consecutive weeks. This administration regimen improved procedural, spatial, and working memory deficits as assessed by the passive avoidance, Morris water maze, and Y-maze tasks, respectively. It also attenuated histological damage and amyloid-beta plaque formation in the hippocampal region and decreased expression levels of pro-inflammatory factors in the hippocampus and cerebrum, while it reduced oxidative stress markers (malondialdehyde in the brain and liver and 8-hydroxy-2′-deoxyguanosine in the plasma). Overall, these findings suggest that long-term administration of WV may alleviate AD-related symptoms and pathological phenotypes.
El estudio del teatro griego clásico: la importancia de la evidencia arqueológica
Authors: Reznik Carolina 
Published: March 2023

El teatro como fenómeno artístico y como objeto de estudio es fascinante. Como toda actividad performativa, se manifiesta de manera completa en ese instante único y efímero que es la representación teatral. Además de esta característica, el espectáculo teatral está integrado por sistemas significantes de naturaleza disciplinar diversa, la cual -a su vez- se modifica en el conjunto. A la hora de encarar una investigación acerca del teatro en general y del teatro del pasado en particular, es indispensable evidenciar estas problemáticas para no incurrir en simplificaciones.
El presente artículo tiene como objetivo presentar las fuentes disponibles para el estudio del teatro griego clásico[1], tanto materiales como documentales, discutir sus características y destacar sus aportes. La propuesta consiste en mostrar el abanico completo y desmontar la hegemonía que han ostentado las fuentes literarias a lo largo de la historia. Antes de ahondar en ello, presentaremos algunas cuestiones vinculadas con la naturaleza del teatro y con la metodología para su estudio.

[1] Por Época Clásica se denomina tradicionalmente al periodo comprendido entre la revuelta de Jonia en el año 499 A.E.C. (Antes de la Era Común, designación temporal convencional en arqueología clásica equivalente a a.C., antes de Cristo) -año en el que finaliza la Época Arcaica- y el comienzo del reinado de Alejandro Magno en 336 A.E.C. -año en el que se inaugura el período Helenístico-.
La danza contemporánea de la ciudad de buenos aires y su “poética del desencanto”
Authors: Clavin Ayelén 
Published: March 2023

Una parte de las obras de danza contemporánea escénica de la ciudad de Buenos Aires condensa una serie de rasgos que corresponden a formas específicas de inclusión e irrupción de lo real, y configuran una escenicidad desencantada. El denominador común en estas obras es el desencanto, que tiende a suspender o fracturar la ilusión. Según lo definimos en estas páginas, el desencanto da cuenta de una particular interdependencia entre las puestas escénicas y el contexto en el que se crean, en tanto las piezas incluyen, o bien referencias explícitas, o bien marcas, huellas, de las circunstancias de producción y del trabajo de sus creadores/as. En las obras se repiensan y se ensayan alternativas posibles para la relación entre las creaciones, lxs artistas y lxs espectadores/as. Por último, el desencanto implica modos de estar en escena en los que los cuerpos son sede de lo real, es decir, son ese intersticio entre lo “extraescénico” y lo “intraescénico”[1] del trabajo implicado en estas prácticas dancísticas (crear, producir, interpretar, bailar).

[1] Las comillas responden a que, tanto lo extraescénico como lo intraescénico, experimentan un grado de permeabilidad tal, en los casos analizados, que hace difícil definir tajantemente si determinados elementos pertenecen a “dentro” o “fuera”.

Hybrid Culture in Indonesian EFL Textbooks: Policies and Pedagogical Implications
Authors: Sapoetra Jimmy 
Published: March 2023

Hybrid Culture is a new term which reflects the diversity and complexity of the world culture existing today. The term hybrid culture refers to the mixture of several kinds of culture blended or integrated into one new culture which has the characteristics of the old and new culture it represents. In the context of EFL learning in Indonesia, many EFL textbooks do not really cover the hybridity of the culture which creates the pedagogical implications in the future of education. The majority of the textbooks either focus on the local or target culture. They do not emphasize the importance of the students to understand that culture is not single-handedly original in its nature but consists of many external factors. This study attempts to examine such a phenomenon. The data were taken from 3 (three) local EFL textbooks used in some high schools in Indonesia. The researcher uses the Content Analysis method with the cultural content evaluation by Byram and Morgan (1994) and Kilickaya (2004). They proposed a qualitative evaluation checklist with a list of criteria for examining the extent and methods of how culture is presented. There are nine categories from the checklist, namely- social identity and social groups, social interaction, belief and behavior, socio-political institutions, socialization and the life-cycle, national history, national geography, national cultural heritage, stereotypes and national identity (Byram & Morgan, 1994). Then the results were compared and it was found that the textbooks do not clearly represent the hybrid culture in their content.

Las infecciones oportunistas (IO) han marcado el pronóstico en la evolución natural de los pacientes con infección por virus de inmunodeficiencia humana (VIH).
Objetivo: conocer las IO más frecuentes y establecer su relación con el conteo de linfocitos T CD4+ (LTCD4+) puede mejorar nuestra práctica clínica y favorecer un diagnóstico temprano, uso de terapias empíricas y tratamiento dirigido oportuno.
Material y métodos: estudio observacional, retrospectivo, con el propósito de describir las características y variaciones de las IO diagnosticadas por clínica, métodos directos o indirectos, que se desarrollan en los pacientes con VIH en relación con su conteo LTCD4+ que ingresan a una institución de tercer nivel de atención en Cali (Colombia). Se incluyeron pacientes adultos hospitalizados entre enero 2018 a enero 2019 con diagnóstico de infección por VIH/SIDA y con antecedente o IO al momento del ingreso; se excluyeron menores de 18 años y gestantes.
Resultados: se obtuvo una muestra de 190 pacientes con al menos una infección oportunista, del cual 65.3% eran hombres con una edad mediana de 37 años (29.0-46.0), para las mujeres de 35.5 años (31.2-43.0). El 83% se encontraba en clasificación C3 al ingreso, 86% con recuento de LTCD4+ ≤ 200 cels/mm3. De las IO las más frecuentes fueron, tuberculosis con 28.4%, neumocistosis con 27.9% y toxoplasmosis con 27.4%.
Conclusiones: en nuestra población, pese al avance y mayor disponibilidad de terapia antirretroviral de alta efectividad, la mayoría de los pacientes con infección por VIH se hospitalizan en estadios avanzados con infecciones oportunistas, en algunos casos dos o más de manera concomitante y con evidencia de compromiso virológico e inmunológico severo

Recuperando estado de salud y egreso a domicilio.
Discusión: las complicaciones de realimentación aumentan cuando se inicia una tasa calórica alta. La fórmula enteral estándar contiene 54% de carbohidratos, el cual contribuye al riesgo de desarrollar SRL. Se desconocen las consecuencias de TCA y COVID-19 y es probable que se vuelva más evidente con el tiempo.
Integrating Machine Learning and Mathematical Optimization for Job Shop Scheduling

Published: March 2023

<p>Job-shop scheduling is an important but difficult combinatorial optimization problem for low-volume and high-variety manufacturing, with solutions required to be obtained quickly at the beginning of each shift. In view of the increasing demand for customized products, problem sizes are growing. A promising direction is to take advantage of Machine Learning (ML). Direct learning to predict solutions for job-shop scheduling, however, suffers from major difficulties when problem scales are large. In this paper, a Deep Neural Network (DNN) is synergistically integrated within the decomposition and coordination framework of Surrogate Lagrangian Relaxation (SLR) to predict good-enough solutions for subproblems. Since a subproblem is associated with a single part, learning difficulties caused by large scales are overcome. Nevertheless, the learning still presents challenges. Because of the high-variety nature of parts, the DNN is desired to be able to generalize to solve all possible parts. To this end, our idea is to establish “surrogate” part subproblems that are easier to learn, develop a DNN based on Pointer Network to learn to predict their solutions and calculate the solutions of the original part subproblems based on these predictions. Moreover, a masking mechanism is developed such that all the predictions are feasible. Numerical results demonstrate that good-enough subproblem solutions are predicted in many iterations, and high-quality solutions of the overall problem are obtained in a computationally efficient manner. The performance of the method is further improved through continuous learning. </p>

<p>Nearly 15% of the global population is affected by disabilities impacting mobility. Monitoring foot pressure distribution during gait is a fundamental aspect of evaluating rehabilitation. Wearable systems provide a portable alternative to stationary equipment monitoring gait without laboratory space limitations. However, wearable sensors in some applications present challenges in the calibration, sensitivity, and human-sensor interface, requiring application-specific sensors. This study aimed to develop wearable sensors where the structural and material properties can characterise the sensitivity and range of measurement during the design phase. We developed wearable piezoresistive sensors using additive manufacturing to create mechanical metamaterials with embedded pressure-sensing capabilities. The sensors were fabricated in TPU using SLS and graphene ink infusion processes. Three structural designs were developed for different measuring ranges (0 – 50 N, 0 – 100 N, and 0 – 150 N) using body-centred cubic lattices constructed via pyramid unit cells. Two graphene infusion processes were evaluated. We tested the sensors' mechanical and piezoresistive behaviour, measuring the compressive force, strain, and electrical resistance across the sensor. We analysed the influence of structural dimensions and the infusion process on the piezoresistive behaviour. The measuring range was affected mainly by tuneable structural dimensions. The infusion process influenced the piezoresistive sensitivity and affected the linearity response. The results indicate the characterisation of the sensitivity of piezoresistive sensors based on structural parameters and material properties. Mechanical metamaterials could embed pressure sensing in wearables, allowing for customisation based on design parameters using additive manufacture and graphene inks. </p>
Variable Carrier Phase Shift Method for Integrated Contactless Field Excitation System of Electrically Excited Synchronous Motors
Authors: Ayaz Enes , Keysan Ozan 
Published: March 2023

<p>This paper presents a novel contactless field excitation~(CFE) system based on wireless power transfer~(WPT), which utilizes the existing voltage source inverter~(VSI) of the motor drive for electrically excited synchronous motors~(EESMs). In conventional CFE systems, an extra high-frequency converter is required to excite the field winding. In this paper, it is proposed to utilize existing voltage switching harmonics of the VSI for exciting the field winding while the low-frequency modulated component is used to drive the motor. In the proposed system, a novel variable carrier phase shift method~(VCPSM) is developed to achieve constant input excitation voltage for the WPT part independently from the motor operation. In addition, a hybrid frequency detuning control method is introduced to adjust the field current. For experimental validation, a small-scale prototype with 100~V DC-link and 60~kHz switching frequency is established. It is observed that the field current could be kept almost constant at 5~A under different motor driving conditions operations regarding modulation index and fundamental frequency. Also, it is shown that the field current could be reduced by detuning the switching frequency. In brief, without an additional active converter and only with a software update, a cost-effective CFE system for EESMs can be easily implemented.</p>

Published: March 2023

<p>Understanding the success of augmentative exoskeletons is critical to their impact on society. Many exoskeletons are developed to address impairments stemming from neuromotor pathology, which provides guidance for understanding their abilities; however, for augmentative exoskeletons that assist able-bodied users, a clear metric of success remains an open question. In this study, we leverage an approach from economics--the Vickrey second-price auction--to quantify the economic value added by lower-limb exoskeletons during uphill walking. In our protocol, participants describe the monetary compensation needed to continue walking uphill for consecutive bouts of two minutes. To incentivize truthful descriptions of participant's “price to walk,” their compensation amounts were provided as bids in Vickrey auctions before each bout. We compared these data across different conditions to determine the marginal value of the exoskeleton weight, assistance, and weight + assistance. Our approach found that the total value of the exoskeleton and its assistance was modest ($3.40/hr, SD: $3.35/hr); while most participants found the assistance itself valuable ($19.76/hr, SD: $19.43/hr), this value was nearly offset by the cost of wearing the exoskeleton weight (-$18.59/hr, SD: $18.28/hr). Our approach and results demonstrate that economic value can be a powerful tool to develop exoskeletons that maximize user benefit. </p>

<p>We consider the problem of finding an array of antennas that provides a desired distribution of signal strength in an urban environment. Our approach is based on a discretized Maxwell equation for the electromagnetic field. This equation can be solved numerically and provides training samples for a deep learning algorithm. Finally, the deep learning algorithm, based on a multi layer perceptron, is used to retrieve antenna arrays for a desired signal distribution. In our example we obtain for the retrieval a mean success rate of 90%. </p>

Parental Narcissism and Its Impact on Child: Amadu Maddy’s Novel “No Past No Present No Future” as Example
Authors: Kassaw Abera , Mengistu Melakneh 
Published: March 2023

The study explores parental narcissism and its impact on child, adopting Amadu’s novel ‘No Past, No Present, No Future’ as example to show how the theory of narcissism could be applied to reexamine Anglophone African novels. The study specifically focuses on how family dynamics and social issues have influenced the mental activities of the major character, Ade and how he fails to cope with the pressures of everyday life, often resulting in psychic dispossession. As such, the researcher uses textual analysis and descriptive criticism approach to unravel the causes and consequences of Ade’s narcissistic disturbance. The theory of narcissism which is dominantly informed by Freudian and post-Freudian approaches to psychology is used to account for the intra-psychic forces which operate within the narcissistic character, Ade and his parents in Amadu’s ‘No Past, No Present, No Future’. The study reveals the existence of character with narcissism, whose psychopathology is as a result of the complementary roles of narcissistic parent-child relationship. The study further reveals that Ade’s narcissistic disturbance is characterized by the fear of being dispossessed, narcissistic form of loving, aggression, and grandiosity.
