Türk Mutfağında Sürdürülebilirlik ve Sıfır Atık Kapsamında Limon Kabuğunun Değerlendirilmesi (An Analysis of Lemon Peel in Turkish Cuisine with Regard to Sustainability and Zero Waste)
Authors: BOZKURT Nisa Nur , ÇETİN Kadir
Published: October 2024

Bu araştırma, Türk mutfağında sürdürülebilirlik ve sıfır atık yaklaşımları çerçevesinde limon kabuğunun değerlendirilmesini araştırmaktadır. Gıda atıkları, küresel ölçekte ciddi bir sorun teşkil etmekte olup, sürdürülebilirlik ve gıda güvenliği açısından önemli tehditler oluşturmaktadır. Türkiye'de yılda kişi başına 93 kg gıda atığı oluşmaktadır ve bu atığın büyük bir kısmı bozulabilir gıdalardan oluşmaktadır. Limon kabuğu, besleyici değeri yüksek biyoaktif bileşikler içermesine rağmen yaygın olarak atık olarak değerlendirilmektedir. Araştırma, geleneksel salamura yöntemi ile limon kabuğunu yenilebilir hale getirerek Türk mutfağına kazandırmayı amaçlamaktadır. Araştırmada, limon kabukları üç farklı tuz konsantrasyonu (%5, %10, %20) kullanılarak salamura edilmiş ve duyusal analizler yapılmıştır. %20 tuz konsantrasyonunun en iyi sonucu verdiği tespit edilmiştir. Geliştirilen ürünler (cheesecake, mozaik pasta, zerde) duyusal analizlerle değerlendirilmiş ve özellikle ticari işletmelere uygunluk açısından olumlu sonuçlar elde edilmiştir. Sonuçlar, limon kabuğunun değerlendirilmesi ile gıda atıklarının azaltılmasına ve sürdürülebilir mutfak uygulamalarının teşvik edilmesine önemli katkılar sağlamaktadır. Araştırma, Birleşmiş Milletler Sürdürülebilir Kalkınma Hedefleri ’ne (SKA 2: Açlığa Son ve SKA 12: Sorumlu Üretim ve Tüketim) katkı sağlama potansiyeline sahiptir. Gıda atıklarının besin değeri ve sağlık faydaları konusunda tüketici bilincinin artırılması ve limon kabuğunun kullanım alanlarının genişletilmesi önerilmektedir.

Safety analysis of wind-induced resuspension of radioactive materials from the Techensky reservoir cascade coastline
Authors: Pykhova A. V. , Ekidin A. A. , Vasyanovich M. E. , Antonov K. L.
Published: October 2024

The paper provides an assessment of the probability and consequences of external events capable of leading to an incident with a breach of established safety barriers restricting the spread of radioactive substances along the coastline of the Techensky reservoir cascade. The initiating events for such an incident could be adverse meteorological conditions resulting in a decrease in the water level in the cascade water bodies below the specified design levels. Drying out the surface of previously inundated sections of the coastline will create an extensive source of atmospheric contamination by technogenic radionuclides during wind-induced resuspension. The probable area of the dried-out sections will be 0.02 — 0.08 kml for reservoir V-3, 0.06 — 0.28 kml for reservoir V-4, 0.19 — 0.90 kml for reservoir V-10, and 0.47 — 2.19 kml for reservoir V-11. The cumulative inventory of 137Cs and 90Sr in the specified area exceeds 105 Bq/ml. The activity released into the atmosphere within an hour will range from 3.69∙108 to 8.48∙1011 Bq for the wind speeds of 5 m/s and 20 m/s, respectively. The probabilities of joint occurrence of strong winds and drought conditions are 6.8∙10-7 per year for a wind speed of 20 m/s and 2.1∙10-3 per year for a wind speed of 5 m/s. The highest values of effective dose for the population of the nearest settlements, reaching 1-3 μSv in the first 10 days and over 200 μSv in the first year, are achieved under extreme wind loads with wind speeds of 20 m/s or more.

Published: October 2024

The publication continues the series of research addressed to the dynamics of 137Cs concentrations in agricultural products after the Chernobyl accident. The purpose of the present paper was to analyze the data describing the changes of 137Cs concentrations in cow milk. The information on countermeasures in animal breeding is presented, the system of radiological monitoring of milk contamination is described. It is shown that the dynamics of 137Cs concentrations in milk was seriously affected by the implementation of agrotechnical and veterinary measures. Effective half-lives of 137Cs concentrations in milk in the first period after the accident (1987-1992) ranged from 1 to 2.0 years. In the subsequent period (1991-2015), the reduction of milk contamination slowed down and the half-lives ranged from 5 to 25 years depending on the scope of remediation works and 137Cs aging in the soil.
The importance of supervisor support for the work outcomes and psychological well-being of Malaysian low-income working mothers
Authors: Zulkifli Syara Shazanna , Hamzah Hazalizah
Published: October 2024

Low-income working mothers are susceptible to well-being issues. However, research on the interplay between supervisor support and the work outcomes and psychological well-being of Malaysian low-income working mothers is scarce. Therefore, this study identifies the relationship between work outcomes (work stress, work-life balance, workplace bullying) and the moderating role of supervisor support in the psychological well-being of working mothers. Using purposive sampling, data were obtained from a survey of 269 respondents (M-age = 38.15, SD-age = 8.14) employing offline and online methods. The participants completed the demographic section, Psychological Well-being Scale, Work Stress Scale, Work-life Balance Checklist, Malaysian Workplace Bullying Index, and Supervisor Support Scale. Structural equation modelling analysis showed that work stress was the main contributor to psychological well-being (β = -0.41, t = -2.87, p = .004), followed by supervisor support (β = 0.29, t = 3.34, p .001), and workplace bullying (β = -0.23, p = .048). In addition, supervisor support significantly weakened the impact of work stress on psychological well-being (β = -0.14, t = -2.00, p = .045). The study concludes that supervisor support enhances psychological well-being and reduces the negative burden of work stress on the psychological well-being of Malaysian low-income working mothers. Identifying the most significant contributors to psychological well-being can help working mothers to become more aware of the negative side effects of work, and encourage them to find effective solutions to maintain their psychological well-being. Finally, the study emphasizes for supervisors and human resource personnel the importance of supervisory roles in improving the work environment and providing strengthened support for psychological well-being.

Gökyüzü tarih boyunca insanlık için bilinmezliği ile ilgi duyulan bir yer olmuştur. Eski çağlarda insanlık göksel olaylar ve cisimlere farklı anlamlar yüklemiştir. Yine eski çağlarda gökyüzünün gözlemlenmesi zamanın ölçülmesinde referans olmuştur. Evren ve doğa hakkında bilgilerin zaman geçtikçe değişmesi ve artması gökyüzü hakkında anlayışın da değişmesine sebep olmuştur. Özellikle endüstri devrimi ve sonrasından, 21. yüzyıla değin bilim/teknolojinin ilerlemesi evren ve gelecek hakkında farklı tasavvurların gelişmesini sağlamıştır. Bu durum edebiyattan, müziğe sanatın birçok alanında bilim kurgu ve gelecekçi kavramları gündeme getirmiştir. Günümüzde sanatsal kaygılarla üretilmiş uzay görsellerinin yanında uzay temalı grafik illüstrasyonlar bilimsel yayınların anlaşılmasında yardımcı olmaktadır.

Assessments of hydrogeochemical characteristics, water quality, and health risk of groundwater of Chapi-Nawabganj District of Bangladesh
Authors: Islam Md. Zahidul , Mostafa M. G.
Published: October 2024

A total of 60 groundwater samples were collected over three seasons, aiming to assess hydrochemical characteristics, water quality, pollution level, and health risk. The concentration of Fe, Mn, and Pb exceeded almost 100% of samples in three seasons. The groundwater was found to be highly contaminated with Cd and Cr in the pre-monsoon and Ni in the monsoon. The order of major ion and trace metal concentrations is as follows: Ca2+ > Na+ > Mg2+ > K+; HCO3− > Cl− > SO42− > NO3− > PO43−, and Fe > Mn > Pb > Cd in three seasons. The groundwater was Ca-Mg-HCO3− type. The study suggests that the contamination sources are mostly geogenic as well as slightly anthropogenic. The water–rock interactions are the dissolution of calcite and dolomite, along with silicate weathering, which controls the hydrochemistry of the groundwater. The indices, including the Water Quality Index (WQI), and the Canadian Council of Ministers of the Environment (CCMEWQI), revealed that the groundwater quality in the area was moderately polluted. The Heavy Metal Pollution Index (HMPI) and human health risk assessment (HRA) illustrated that groundwater is a significant health hazard, indicating it is unsuitable for human consumption and suggesting treatment before drinking.
Determining Groundwater Table in Slopes With Horizontal Drains and Design Framework for Length and Spacing
Authors: Lakruwan Mihira , Kamura Akiyoshi , Kazama Motoki
Published: October 2024

Horizontal drains (HDs) are commonly implemented in slope stabilization to reduce the pore water pressure (PWP); however, they also cause complex three-dimensional (3D) variations in the groundwater table (GWT), which require intricate 3D flow models. To address this challenge, we propose a novel semi-empirical method based on a series of numerical simulations validated through numerical and field studies to determine the GWT of a slope with HDs. Subsequently, the proposed method was extended to calculate the average PWP (U) acting on a predefined slip surface via linear integration. The decrease of U (ΔU) resulting from HDs can be used to evaluate the performance of HDs. To create design charts that consider the impact of length and spacing of HDs on ΔU for a specific slope, we developed a Python-based computer program. Two case studies were conducted, which showed that ΔU increases with longer HDs and shorter spacing. The results also indicated that extending the HDs beyond a particular length does not significantly affect ΔU; it is highly sensitive to the spacing in short HDs and not sensitive in long HDs. Furthermore, we found that the total length of HDs required to achieve a target ΔU is less in wide spacings than in short spacings. In conclusion, long HDs with wide spacings are more effective and economical. Owing to the unique nature of each slope stability problem, this study offers a practical tool for analyzing the effectiveness of HDs instead of providing a general guide.

Published: October 2024

AbstractThis study aims to determine whether public expenditures in meeting basic human needs affect community welfare. This study uses data on realizing the spending on education, health, and social protection as a proxy for public expenditures and the human development index for community welfare. This study indicates that education and health expenditures have a significant positive effect, while social protection expenditures have a significant negative effect. This study confirms disclosures in the Audit Report of the Audit Board of the Republic of Indonesia. The disclosures in Provincial Government Financial Statements in Indonesia state that the regional government prioritized meeting basic needs, education, health, and social on mandatory spending to improve the quality of community life. This research implies that social protection expenditure is not optimal for developing human capabilities. Keywords:Education Expenditure, Health Expenditure, Social Protection Expenditure, Human   Capability, Community Welfare
Modern Eugenics: Ramifications of Genetic Stereotyping (Preprint)
Authors: Siegel Hayden , Berger Israel
Published: October 2024

UNSTRUCTURED

We want to know where we come from and what health risks we may face. With that in mind, modern geneticists attempted to facilitate answers to these questions by dividing humankind into demographics by which they then cataloged genetic markers. While at first glance this seems like a rational approach to the task of answering these questions, this method has led to some of the greatest atrocities humankind has ever seen, multiple times over, by dehumanizing patients into categories which ignore their personal history, identity, as well as their genetic profile by assuming various factors to include them as part of a demographic which will never fully represent them. The goal of this paper is to analyze the ramifications of such methodologies to encourage a dialog for a more accurate along with a more patient aware method of conducting genetic studies. Statistical data on antisemitic hate crime activity from the United States Department of Justice along with the Anti-Defamation League was compared to the publication of genetic studies which have traditionally been a part of the United States national curriculum on genetics as well as private studies which attributed genetic markers and disorders to the Jewish people. These studies often ignore the scientific method to base their findings on assumptions and there is not a similar tradition of studying non-Jews who do not belong to another minority in the same manner resulting in an inherent bias within the field of study which disproportionately hectors the Jewish people in academia.
Assessing climate change’s impact on cardiopulmonary health in the canton of Valais: a pilot study protocol (Preprint)
Authors: Portela Dos Santos Omar , Alves Paulo Jorge Pereira , Verloo Henk
Published: October 2024

BACKGROUND

Climate change is a challenge for health and humanity. In Switzerland, the canton of Valais is considered one of the driest regions in the Alps. Its air pollution can reach high levels; temperatures reach extremes of cold and heat. These climatic changes are harming the population’s health and well-being. According to the Swiss Health Observatory, the emergency departments of Switzerland’s 100 largest hospitals treated 1.722million cases in 2016, equivalent to 4,718 admissions daily. In Valais, 75,000 patients consulted at Sion’s emergency department in 2022.

OBJECTIVE

This pilot study aims to estimate climate change’s impact on the cardiopulmonary comorbidities of Valais’ population and explore adult patients’ knowledge of climate change’s consequences for their health. The study’s findings will inform planning and facilitate estimations of how the care for adult patients presenting at Sion’s emergency department needs to adapt and improve, and what changes must be made in the domains of health promotion and disease prevention. The feasibility and acceptability of the patient selection and data collection processes will also be explored.

METHODS

The pilot study will use a convergent parallel mixed-methods design. Data collection will occur over a year, from 21 September 2024 to 20 September 2025. Descriptive statistics of the quantitive phase will be calculated, and the qualitative phase will undergo a thematic analysis.

RESULTS

The 12-month recruitment period is expected to provide a sample of at least 60 patients. We will explore the process of recruiting patients to the study, the reasons for their consultation at Sion’s emergency department, their triage level, their sociodemographic profile, and their knowledge about climate change and its potential links to their emergency department visit.

CONCLUSIONS

The pilot study’s results will enable us to test the feasibility of the methods and procedures needed for a larger study and to search for the effects of potential associations between specific changes to the characteristics of Valais’ microclimate and its population’s health. Associations will enable us to establish typical profiles of the adult patients who consult at Sion’s emergency department. The qualitative phase’s results will help to reveal and explore those patients’ personally and socially determined perceptions, experiences, knowledge and feelings about climate change.

Sentido y valor de los mercados costeros de lugar en Chile
Authors: Saavedra Gallo Gonzalo , Bello Maldonado Álvaro , Díaz Álvarez Asunción , Luco Busto Javiera
Published: October 2024

This article analyses the structural dynamics of social life at five local coastal markets (LCMs) on the Chilean coast (Calbuco, Puerto Montt, Valdivia, Valparaiso and Tongoy). In a semantic narrative framework, we use ethnographic methodology to demonstrate the opacity of local markets—particularly LCMs—in terms of economic and community life.  Opacity is a social condition. However, the background reveals profound significance that bears witness to and partially portrays the complexity of markets as places of business, livelihood, life projects and social mobility, where individuality is necessarily intertwined with the community. Our conclusions show that these LCMs go beyond the orthodox definitions that reduce the economy (and the markets themselves) to cost-benefit-motivated interactions between individual agents. Instead, markets go against the grain of this instrumental reductionism and offer remarkable potential for re-thinking, imagining, constructing and co-constructing areas (coastal areas in our analysis) based on collective experience.

Gradientes de humanidad en el pensamiento nahua: más allá de la dicotomía humanos y no humanos
Authors: Milanezi Gabriela
Published: October 2024

A partir de los mitos cosmogónicos y del proceso de conformación de la persona entre los nahuas de la Sierra Norte de Puebla, se constata que la humanidad y lo humano no son categorías fijas, sino condiciones adquiridas en la medida que ciertas pautas de conducta son adoptadas. Consecuentemente, el que deja de comportarse según la moral social nahua se “transforma” en “animal”. A la vez, si los seres humanos no cumplen las normas de interacción basadas fundamentalmente en la reciprocidad, pueden retroceder a un estado de “animalidad”, lo que equivaldría al “fin del mundo” o la disgregación de los valores y las instituciones que conforman la sociedad nahua o maseual. Con ejemplos etnográficos, este artículo problematiza el uso reciente e indiscriminado de la dicotomía humanos/no humanos para aludir y clasificar a los habitantes del cosmos indígena. El objetivo es demostrar que, según la ontología nahua, el conjunto de los existentes no es fundamentalmente dividido en esas dos categorías antagónicas y esenciales, sino que es pensado en términos de gradientes de humanidad.
Arquitectura y turismo en Michoacán (1935-1950) Pátzcuaro, Jiquilpan y Apatzingán
Authors: Ettinger Mc Enulty Catherine Rose
Published: October 2024

La historia de la arquitectura del periodo de la posrevolución en México se ha enfocado en las obras construidas para atender salud, educación y vivienda, considerándolas reflejo de las prioridades de estado, sin reparar en una cuarta prioridad: el turismo. A partir de los años veinte, particularmente durante el periodo en que Lázaro Cárdenas fue presidente de México (1934-1940), se dio gran impulso a la actividad turística y a la construcción de equipamientos que la apoyaran. La visión de Cárdenas en relación con el turismo no sólo llevó a la construcción de una red carretera, hoteles modernos y estaciones de servicio, sino también a la creación de un imaginario sobre México que, en lo que a arquitectura atañe, enalteciera el valor de la vida pueblerina. Este trabajo aborda la arquitectura para el turismo en tres ciudades michoacanas con atención a las escalas urbana y arquitectónica. Identifica la manera en que se gestó la idea de poblado típico y se desplegó en remodelaciones urbanas, y reseña algunos ejemplos de arquitectura de servicios turísticos: hoteles y estaciones de servicio. Es un trabajo elaborado desde la historia de la arquitectura con base en fuentes documentales de archivo, fuentes gráficas como tarjetas postales y a partir de los mismos edificios como fuentes de información. Argumenta que la arquitectura para el turismo promovida desde el estado no sólo proveía servicios modernos, sino que también se conformaba al imaginario de México rural, de casas blancas con teja roja, que el visitante deseaba experimentar.
El paisaje lacustre y el sentido de identidad: transformaciones y resiliencia en las poblaciones de la cuenca del Alto Lerma
Authors: Sugiura Yamamoto Yoko
Published: October 2024

La cuenca del Alto Lerma es reconocida por sus humedales, volcanes, bosques circundantes y el gran río Lerma. Desde hace alrededor de 3000 años hasta la actualidad, los pobladores de esta región han venido interactuando con su entorno lacustre. Resultado de esta milenaria convivencia se tiene por su particular forma de comprender el paisaje, término que, con el paso del tiempo, ha ido diversificándose de acuerdo con las perspectivas teóricas específicas.
En el presente texto, a partir del paisaje concebido como un constructo social-histórico, se relatan los vaivenes de las interacciones entre los grupos lacustres y sus humedales desde los tiempos prehispánicos hasta apenas hace unas décadas.          Mediante un proceso de constantes negociaciones entre ellos, se fue construyendo una percepción particular del paisaje. A veces, éste manifiesta su carácter dinámico, mientras que, en otras, parece pervivir sin cambios perceptibles. Todo cambio en la percepción del paisaje puede ser efímero puede ser efímero, pero, también, puede perdurar y provocar una transformación profunda o una resiliencia ante ella. En este complejo proceso, la gente va tejiendo su razón de existencia e identidad. Así, el verdadero significado del paisaje lacustre que va creando una historia particular se encuentra en un péndulo precario entre el ser humano y los humedales.      
                          Si el paisaje es un constructo socialmente condicionado, se presume, entonces, que, a lo largo de la historia del valle de Toluca, la construcción del paisaje lacustre ha tenido múltiples facetas, en ocasiones, provocadas por los episodios ambientales y, en otras, por las causas antrópicas.
Evolución de las prácticas del cuidado
Authors: Barrio Fioresta Paola Andrea , Candela Gustavo David
Published: October 2024

Las prácticas del cuidado hacia el otro han evolucionado conjuntamente con la propia evolución biológica de nuestra especie. El objetivo de esta investigación es discutir si estas acciones se relacionan a una condición innata, si son incorporadas culturalmente mediante el aprendizaje o una conjunción de ambas, y cómo estas acciones son conceptualizadas e internalizadas actualmente en nuestra sociedad. Para ello se efectuó por un lado, un recorrido bibliográfico de investigaciones etnográficas y paleoantropológicas y, por el otro, un estudio sobre la percepción humana y los motivos que impulsan la existencia de estas prácticas en comunidades actuales, prácticas que, en los casos de discapacidad, se han sostenido en el tiempo. Si bien los resultados corresponden a una pequeña muestra del universo posible y no resuelven la dicotomía naturaleza-cultura de nuestra pregunta, este trabajo puede ser un disparador para generar una serie de debates interdisciplinarios e invita a investigar sobre el proceso evolutivo de la conducta de cuidado en la humanidad.

Published: October 2024

“Ganarse la vida” o “las diversas formas de ganarse la vida”, es un título que no puede ser más que acertado. Abre un campo semántico de gran riqueza etnográfica, etnológica y antropológica, que vigoriza el objeto de estudio de quienes nos dedicamos al campo de los estudios sobre la cultura. No obstante ello, este título puede ser tramposo. Si lo que define nuestra condición actual es el cambio, a ritmos insospechados, sin distinción de lugares y actores, por inclusión o exclusión, en todos los intersticios de la vida y la sociedad, debiésemos esperar un volumen II, III y IV, sobre “las formas de ganarse la vida”, ya que éstas son y serán infinitas. Por tanto, más que un libro, corresponde a un programa de investigación, que puede ser un trabajo colaborativo de largo aliento. No es una cuestión privativa sólo de los editores, sino que nos involucra a todos, porque aún cuando a muchos no nos guste el mercado como el promotor del cambio, estamos en él.

Authors: Solano-Zamudio Milton-Fabián , Castañeda-Gamboa Gloria-Irina
Published: October 2024

Este artículo explora y analiza las barreras y oportunidades para participar en la educación superior que perciben mujeres afrocolombianas, directivos y docentes de la Institución Universitaria Antonio José Camacho de la ciudad de Cali, Colombia. Es un estudio cualitativo, para la recolección de los datos se realizaron grupos focales con estudiantes de cuatro facultades y entrevistas con directivos y docentes. Sus narrativas develan que son mujeres reflexivas, auto-críticas con percepción de logro y confianza para ser interlocutoras ante la comunidad universitaria. Sería importante crear transformaciones en ese mismo sentido en la educación, con miras a construir espacios de participación que contengan una perspectiva inclusiva, diversa y pluriétnica.
Autoavaliação institucional das Instituições de Ensino Superior no Brasil
Authors: Dos-Santos-Oliveira Ivan , Rothen José-Carlos
Published: October 2024

Neste artigo, fazemos o resgate histórico da concepção e dos princípios fundamentais para a autoavaliação institucional no contexto do Sistema Nacional de Avaliação da Educação Superior, desde 2003 até os dias atuais; abordando sua regulamentação e sua efetiva implementação nas instituições de ensino superior brasileiras. Para isso, foram analisadas e discutidas as construções conceituais e práticas elaboradas a respeito da autoavaliação institucional em documentos oficiais brasileiros. Concluimos que a autoavaliação institucional foi inicialmente pensada para ser o ponto de partida e o instrumento central do processo avaliativo, mais, ao longo do tempo, foi perdendo sua centralidade para a avaliação externa e para o exame de desempenho estudantil, devido à complexidade da prática autoavaliativa nas instituições de ensino superior brasileiras.
Marginación y cobertura en educación superior: el desafío de las brechas
Authors: Pérez-Díaz Ana-Beatriz , Pimentel-Linares Gabriela , Flores-Buendia Jocelyn-Itzel
Published: October 2024

El artículo analiza el efecto de la marginación en la cobertura en educación superior en México en 2010 y 2020. La discusión se inserta en una literatura que ha profundizado en los determinantes socioeconómicos de la participación en ese nivel educativo. Se condujo un modelo de regresión lineal simple para medir la relación entre el índice de marginación y la tasa bruta de cobertura en las 32 entidades federativas. Los resultados advierten una fuerte asociación entre ambas variables. Así, se sostiene que una reducción en la marginación resulta en mayores oportunidades de ingreso a la educación superior. La conclusión principal es que, si bien se observan avances en esta dirección, persisten las brechas regionales. Por ello, es necesario repensar la formulación de intervenciones públicas de política social y la integración de un enfoque de brechas que fortalezca la inclusión, la equidad y la justicia.
Entre Benjamin y la escuela: un Angelous Novus que cruza
Authors: Anaya-Torres Edgar-Daniel
Published: October 2024

El ensayo relaciona los conceptos escuela-progreso como resultado de la modernidad que esboza Benjamin, para proveer la posibilidad de que la educación escape a esa mirada del pasado, a ese devenir trazado por una única línea de la historia. La metodología se sistematiza a partir de una constelación, donde los elementos se acomodan de forma no secuencial, como fragmentos que a partir de la relación con películas y libros proponen metáforas para observar espacios vacíos que no ha sido posible iluminar. Por último, se busca generar una idea que permita encontrar la relación entre pensamiento y educación, como ruptura o fractura de la historia y con ello de la realidad, para buscar una posibilidad de pensar en lo que no queda iluminado, lo no pensado.
Formación doctoral en Paraguay: situación actual y retos pendientes
Authors: Diaz-Villalba Laura , Castelló Montserrat
Published: October 2024

La formación doctoral en Paraguay evoluciona de manera paulatina y ha ido consolidándose en los últimos años con una tendencia a la homogeneización de los programas de doctorado existentes en el país. El objetivo del presente estudio es doble: en primer lugar, caracterizar el ecosistema contemporáneo de la formación doctoral en Paraguay y, en segundo lugar, analizar los retos que persisten, en ocasiones en estado latente. Los principales hallazgos se relacionan con la falta de una cultura investigativa sólida, lo que impide la consolidación de líneas de investigación, mantiene a los docentes en situación de precarización y limita el desarrollo de investigadores con perfiles diversos, lo que, además, repercute negativamente en la formación doctoral y, en última instancia, a la investigación y la innovación en el país. Los resultados apuntan la necesidad de poner en práctica las normativas vigentes mediante la voluntad política de las autoridades e instituciones reguladoras.
La praxis profesional en el Modelo Humanista Integrador basado en Capacidades de la Universidad Autónoma de Tlaxcala
Authors: Ramírez-Vicente Ernesto
Published: October 2024

El Modelo Humanista Integrador basado en Capacidades de la Universidad Autónoma de Tlaxcala significa una revitalización necesaria, innovadora y relevante de los planes de estudios universitarios. Las competencias de corte neoliberal son sustituidas por capacidades a través de una noción filosófica, la praxis, que integra la formación profesional con la humanística en el Seminario de Integración de la Praxis Profesional en todas sus licenciaturas desde el primer semestre. Se reorienta así el perfil de egreso de los estudiantes hacia un profesional capacitado, pero con un profundo compromiso social. Se reflexiona sobre la necesidad de resignificar epistemológicamente la praxis y el currículum formal desde una perspectiva de transformación para contribuir a la construcción y consolidación de un nuevo paradigma, ya no solo propiamente educativo o económico sino cultural, más allá de las fronteras y particularidades del estado de Tlaxcala.

The establishment of a cost model for complex energy systems based on thermoeconomics can provide technical and economic evaluation indicators for complex energy systems. At the same time, to integrate more renewable energy into the grid, complex energy systems must participate in deep peak shaving. To evaluate the technical-economic performance of complex energy systems involved in deep peak shaving, a novel thermoeconomic cost construction method is proposed based on the production structure diagram, using the gas-steam combined cycle system as an example. These can effectively avoid the derivation error of high-dimensional models, improve the modeling and calculation speed, and obtain the variation trend of system thermoeconomics cost under load changes and operating parameter changes. The results show that the external and internal factor can change the power generator thermoeconomic cost. The power generation cost of the system increases with increasing natural gas price and environmental temperature. When the compressor pressure ratio increases, the power generation cost of the system also increases. At 100% load, the power generation cost reaches its lowest value when the exhaust temperature is equal to 615?C.

A study of the thermodynamic behavior during the selective laser melting process of AlSi10Mg alloy was conducted using a combined numerical simulation and experimental approach. A multiphase flow model incorporating gas-liquid-solid phases was established. The numerical simulation results aligned well with experimental findings, affirming the reliability of the numerical model. Insufficient and excessive laser power densitie,s respectively, led to incomplete fusion defects and spherical pore defects. The evolution of the melt pool was primarily influenced by recoil pressure, Marangoni force, and surface tension, resulting in keyhole formation, convective flow, and liquid surface oscillation as characteristic features of melt pool evolution. Solidification process and mechanical analyses revealed that the central region of the melt pool exhibited smaller temperature gradients and higher solidification rates. Properly increasing the scanning speed under suitable laser power conditions is more conducive to optimizing the solidification structure and enhancing the mechanical properties of selective laser melting components. This study elucidates the thermodynamic evolution mechanism during the selective laser melting process of aluminum-based alloys, providing theoretical support and guidance for optimizing the selective laser melting process.

Published: October 2024

Metal-organic frameworks are beginning to be employed in the thermal
management system of lithium-ion batteries because of its high water
absorption and enthalpy of phase change. However, its cooling performance is
only preliminarily explored used in small cylindrical cells or a single
large cell. The effect on multiple large-capacity cells has not be verified
yet. In this study, a micro heat pipe arrays@MIL-101(Cr) hybrid battery
thermal management system is proposed, and its cooling performance of
different number of battery modules at different discharge rates is studied.
Experimental results show that MIL-101(Cr) is evenly distributed, and the
water vapor adsorption capacity reached 1.65 g/g. The maximum temperature of
the micro heat pipe arrays@MIL-101(Cr) group was 36.42?C in the experiment
of the four-cell battery pack at 1C discharge rate, which was 12.98?C lower
than that of the natural cooling group and 3.05?C lower than that of the
micro heat pipe arrays group. With the increase of the number of cells, the
maximum temperature of the battery pack rises from 43.12?C to 47.37?C, and
the temperature difference rises from 1.53?C to 5.57?C at 2C discharge rate.
As the discharge rate increases, the maximum temperature of the battery
consisting of four cells rises from 36.42?C to 47.37?C, and the maximum
temperature difference rises from 2.87?C to 5.57?C, which suggests that the
current micro heat pipe arrays@MOF based battery thermal management system
be combined with an active thermal management system to ensure temperature
control in high-rate and multi-battery modules.

Image restoration is a critical process aimed at recovering degraded images, often impacted by factors including motion blur, sensor blurring, defocused photography, optical aberrations, atmospheric distortions, and noise-induced blur. The inherent challenge lies in the typical scenario where both the original image and the blur kernel (Point Spread Function, PSF) are unknown. This restorative process finds applications in various fields, including sensing, medical imaging, astronomy, remote sensing, and criminal investigations. This paper introduces an innovative approach to blind image deconvolution based on Nash game theory. Our focus is placed on restoring linearly corrupted images without processing explicit knowledge of the original image or the blur kernel (PSF). The proposed method formulates blind deconvolution as a two-player static game, with one player dedicated to image deblurring and the other focused on estimating the PSF. The optimal solution is characterized as Nash equilibrium, resulting in effective image restoration. Moreover, we present an enhanced game formulation that incorporates fractional-order derivatives. This unique extension has the potential to improve image restoration accuracy and resilience, leading to breakthroughs in blind image deconvolution and practical applications.

In the past few years, to store and transmit image data securely, numerous research initiatives on image encoding have been conducted. The primary objective of the image encryption technique is to safeguard the image by sabotaging the pixel pattern. Researchers suggested a safe, portable, and simple to use image encryption technique in this work. The encryption of the image is done using a bit-wise XOR operation, where the bit-wise operation is applied on each pixel of the plain image with a pseudo-random number that is created by the Lorenz chaotic system, to prevent unwanted access to confidential image data. The results of the experiments demonstrate that the suggested technique offers effective image encryption and decryption. The key stream of the encrypted image is made up of pseudo-random digits generated by the Lorenz Chaotic System. Several experimental tests have been performed, including histogram, correlation, information entropy, and differential analysis. The experimental findings reveal that the suggested approach performs image encryption and decryption efficiently.

Tamazight, Berber, and Amazigh are the multiple names for the same language. It covers a great geographical area including the north of Africa, Sahara Sahel. It is spread principally in Morocco, Algeria, Tunisia, and Mali. In terms of natural language processing, it is considered a low-resource language. This paper presents multiple applications of different machine learning algorithms for part-of-speech tagging Amazigh for the first time. Those algorithms include trigrams 'n' tags (TnT), Brill tagging, hidden Markov model (HMM), Unigram, Bigram, Unigram + Bigram,and conditional random fields (CRF). Also, we present a part-of-speech tagger using CRF with our function of extracting features from the Amazigh language. The importance of finding a performant POS tagger for the Amazigh is to enrich its corpus, which is a main step for other NLP applications. In this research, we used 60000 tokens of annotated Amazigh corpus with 28 tags, and we realized the necessary processing step on it to be in an adequate form for feeding each model. A detailed comparison of the performance results is presented to establish the best one and the results show that our application of CRF model outperforms other techniques.

In agriculture, early detection of crop diseases is imperative for sustainability and maximizing yields. Rooted in Agriculture 4.0, our innovative approach combines pre-trained Convolutional Neural Networks (CNNs) models with data-driven solutions to address global challenges related to water scarcity. By integrating the combined L1/L2 regularization technique to our model layers, we enhance their flexibility, reducing the risk of the overfitting effect of the model. In the orange dataset used in our experiments, we have 1790 orange images, including a class of fresh oranges and three disease categories. Applied on this dataset for classification, our model exhibits notable performance, namely 92.17% for CNN and 97.28% for ResNet-50 model. Evaluated across metrics like accuracy, precision, recall, F1-score, confusion matrix, and cross validation, our approach surpasses traditional classifiers, significantly contributing to smart agricultural and global food resilience amidst mounting water scarcity pressures.
