ABSTRAKBertambahnya populasi penduduk berbanding lurus dengan kebutuhan infrastruktur, salah satunya meningkatnya kebutuhan beton yang berdampak buruk pada pencemaran lingkungan. Upaya untuk mengurangi pencemaran tersebut adalah pembuatan beton ramah lingkungan salah satunya adalah beton geopolimer. Bahan utama geopolimer adalah agregat dan binder yang terdiri dari fly ash dan alkali aktivator. Pada penelitian ini dilakukan analisis untuk mengetahui pengaruh variasi alkali aktivator dalam binder yang digunakan dalam pembuatan geopolimer terhadap kuat tekan geopolimer. Penelitian ini menggunakan data primer dan data sekunder yang dikumpulkan dari berbagai jurnal pada penelitian lain yang telah dilakukan. Dari hasil analisis yang dilakukan menunjukkan bahwa ada dua faktor yang bervariasi dalam penggunaan alkali aktivator yaitu molaritas dan rasio antara NaOh/Na2SiO3. Semakin besar perbandingan NaOH terhadap Na2SiO3 dalam komposisi geopolimer menghasilkan kuat tekan yang lebih kecil. Sementara semakin tinggi molaritas NaOH akan menghasilkan kuat tekan yang semakin tinggi pula.Kata kunci: beton geopolimer, alkali aktivator, molaritas ABSTRACTThe increase in population is needed for infrastructure development, the one that affected by this is the increasing need for concrete. This matter has a negative impact on environmental pollution. Some efforts to reduce this pollution are to manufacture environmentally friendly concrete, one of which is geopolimer concrete. The main ingredients of geopolimers are aggregate and binder consisting of fly ash and alkaline activator. In this study, an analysis was carried out to determine the effect of variations in the alkaline activator in the binder used in the manufacture of geopolimers on the compressive strength of geopolimers. This study uses primary data and secondary data collected from various journals in other studies that have been conducted. From the results of the analysis performed, it shows that there are two factors that vary in the use of alkaline activators, namely molarity and the ratio between NaOh/Na2SiO3. The greater the ratio of NaOH to Na2SiO3 in the geopolimer composition, the lower the compressive strength. Meanwhile, the higher the molarity of NaOH, the higher the compressive strength will be.Keywords: geopolimer concrete, fly ash, activator, molarity

A Symbolic Algorithm for Solving Doubly Bordered k-Tridiagonal Interval Linear Systems
Authors: Thirupathi Sivakumar , Thamaraiselvan Nirmala
Published: August 2023

Doubly bordered k-tridiagonal interval linear systems play a crucial role in various mathematical and engineering applications where uncertainty is inherent in the system’s parameters. In this paper, we propose a novel symbolic algorithm for solving such systems efficiently. Our approach combines symbolic computation techniques with interval arithmetic to provide rigorous solutions in the form of tight interval enclosures. By exploiting the tridiagonal structure and employing a divide-and-conquer strategy, our algorithm achieves significantly reduced computational complexity compared to existing numerical methods. We also present theoretical analysis and provide numerical experiments to demonstrate the effectiveness and accuracy of our algorithm. The proposed symbolic algorithm offers a valuable tool for handling doubly bordered k-tridiagonal interval linear systems and opens up possibilities for addressing uncertainty in real-world problems with improved efficiency and reliability.

Comparison of two anastomosis techniques in terms of postoperative pancreatic fistula development: A retrospective cohort study
Authors: Çiçek Okuyan Gülten , Talu Mehmet
Published: August 2023

Background/Aim: Postoperative pancreatic fistula (POPF) development is a common complication after pancreaticoduodenectomy. Various surgical anastomosis techniques have been proposed to mitigate this risk. This study compares two techniques: the two-layer duct-to-mucosa pancreaticojejunostomy (TLPJ) and the modified layer-to-layer end-to-side duct-to-mucosa pancreaticojejunostomy with jejunal serosa resection (MLLPJ).
Methods: A retrospective cohort study was conducted on patients who underwent pancreaticoduodenectomy between January 2012 and December 2020. The primary outcome was the rate of biochemical leak and clinically relevant POPF (grades B and C POPFs).
Results: The rate of biochemical leak was significantly higher in the TLPJ group than in the MLLPJ group (54.5% vs. 4.0%, P<0.001). Clinically relevant POPFs developed in 5.2% of all patients, with rates of 6.1% in the TLPJ group and 4.0% in the MLLPJ group. Patients with longer surgery durations, increased bleeding, and a soft pancreas texture had significantly higher risk of developing clinically relevant POPFs (P=0.009, P=0.039, and P=0.022, respectively).
Conclusion: The MLLPJ anastomosis technique demonstrated a significant reduction in biochemical leak rates. However, the choice between TLPJ and MLLPJ did not significantly impact the rates of clinically relevant POPFs. Other factors, such as surgery duration, bleeding volume, and pancreas texture, were identified as significant risk factors for the development of these fistulas.

A razão humana dificilmente percebe por que Deus não poderia salvar e santificar os homens singularmente, cada um por si, diretamente, imediatamente, sem intermediários, sem instituições sociais, sem religião organizada, sem meios visíveis, sem ligações a um povo ou a uma comunidade. Não foi fácil para São Pedro, mesmo depois de Pentecostes, como judeu habituado a ver ligada a salvação à pertença de um povo, chegar finalmente a esta conclusão: «Agora reconheço deveras que não há em Deus acepção de pessoas, mas que em toda nação aquêle que teme a Deus e pratica a justiça Lhe é aceito» (At 10,34)...

Published: August 2023

La dificultad al trabajar sobre matrices biológicas y el surgimiento de nuevas drogas hacen de la toxicología un importante desafío analitico. La necesidad de reducir la complejidad y el impacto ambiental de los procesos químicos ha fomentado el desarrollo de estrategias analíticas más eficientes y sostenibles. En esta Tesis Doctoral se desarrollaron distintas estrategias de análisis para la detección de drogas en matrices forenses, dando énfasis, principalmente, a los procesos de preparación de muestra y su acoplamiento instrumental. El primer método fue desarrollado para el análisis de antidepresivos y benzodiazepinas mediante el acoplamiento directo de un dispositivo comercial de microextracción a un espectrómetro de masas de alta resolución, con lo que fue posible reducir los tiempos de análisis y el uso de solventes orgánicos. Otros dos métodos se enfocaron en establecer las capacidades extractivas de polidopamina. Este polímero se usó como material de recubrimiento de dispositivos de microextracción en el análisis de antidepresivos y drogas de abuso en saliva mediante espectrometría de masas, sin una separación cromatográfica previa. Por último, se desarrolló un método de alta sensibilidad mediante cromatografía líquida de ultra alta eficiencia acoplada a espectrometría de masas de alta resolución como método de “screening”. Su aplicación a muestras de sangre postmorten provenientes del Servicio Médico Legal permitió la identificación de fármacos, drogas y metabolitos de distintos grupos farmacológicos. Estas estrategias permitieron el análisis eficiente, y relativamente sencillo, de drogas y fármacos en muestras biológicas con un enfoque más amigable con el medio ambiente.
Influencia de secuencias de ADN en procesos activos que determinan el posicionamiento nucleosomal.
Authors:   , Gutiérrez Contreras José Leonardo
Published: August 2023

La posición de los nucleosomas tiene un gran impacto en procesos celulares que involucran interacción proteína-ADN, como es el caso de la replicación, reparación y transcripción. En Saccharomyces cerevisiae los promotores de genes se encuentran enriquecidos en secuencias homopoliméricas de ADN denominados tractos poli (dA:dT), las cuales se relacionan con la presencia de regiones libres de nucleosomas (NDRs). En otros organismos, como ratón y humano, la presencia de tractos poli (dA:dT) es menor y su distribución es más amplia; sin embargo, mantienen su capacidad de excluir nucleosomas, lo que podría significar que existen mecanismos comunes que se han conservado durante la evolución. ¿Cómo se forman y mantienen los NDRs? Estudios a nivel de genoma completo han determinado que los complejos remodeladores de cromatina dependientes de ATP juegan un papel clave en este fenómeno, donde existen complejos denominados “despejadores”, que abren y forman los NDRs, y complejos denominados “cubridores”, que cierran los NDRs. Además, otros estudios han encontrado una relación entre la acción de los complejos remodeladores de cromatina dependientes de ATP y la presencia de los tractos poli (dA:dT), donde la acción de factores de transcripción también estaría implicada. Sin embargo, aún se desconocen los mecanismos moleculares de la comunicación que existe entre los diferentes elementos que se encuentran en los NDRs. Por este motivo, en el presente trabajo buscamos determinar la influencia de los tractos poli (dA:dT) sobre la actividad remodeladora de nucleosomas de los complejos ISW1a, RSC y ySWI/SNF, los cuales cumplen diferentes roles en la mantención de los NDRs. Además, estudiamos cómo factores de transcripción pueden influir en la dinámica entre estas secuencias y los complejos estudiados. Para llevar a cabo nuestro estudio, usamos sondasmononucleoso-males reconstituidas in vitro que poseían diferentes configuraciones de los tractos poli (dA:dT), con las que se ejecutaron ensayos de remodelación analizando la acción de los complejos purificados. En nuestros resultados hallamos que estas secuencias pueden afectar de manera directa varios aspectos de la acción de estos complejos, como: la unión al nucleosoma, la intensidad de la actividad de remodelación y la dirección en que ejecutan ésta. Además, observamos que la orientación de los tractos poli (dA:dT) afecta diferencialmente a los complejos remodeladores de cromatina estudiados. Por otro lado, encontramos que los factores de transcripción podrían ejercer efectos diferenciales sobre ISW1a y RSC. Estos resultados realzan la importancia y el impacto que tienen los tractos poli (dA:dT) en el posicionamiento nucleosomal y ayudan a dilucidar los mecanismos mediante los cuales estas secuencias ejercen sus efectos.

Fue estudiado el procedimiento de compactificación de Randall-Sundrum (RS) así como sus implicaciones en las soluciones cosmológicas en el contexto de gravedades Chern-Simons (ChS) y Einstein-Gauss-Bonnet (EGB). La primera parte de esta tesis, consiste en usar el mencionado procedimiento de compactificación sobre la acción de la gravedad AdSL4-Chern-Simons en 5D, de la cual se obtuvo una acción Einstein-Hilbert (EH) cuadridimensional extendida con término cosmológico, que incluye campos de gauge ˜k mn µ no Abelianos. El mismo procedimiento de compactificación fue usado en la acción que describe gravedad ChS para el álgebra de Maxwell en 5D, de donde se obtuvo una gravedad de Einstein en 4D extendida con término cosmológico y campos de gauge Abelianos que coincide con la ecuación (29) de (16). Empleando el procedimiento de contracción Inönü-Wigner sobre la acción compactificada obtenida a partir de gravedad AdSL4-ChS en 5D, se encontró la ecuación (29) de (16). Señalamos que los campos de gauge ˜k mn µ pueden ser interpretado como posibles campos vectoriales geométricos del inflatón. En la segunda parte de la tesis, se consideró el Lagrangiano de la acción para gravedad EGB en 5D, a partir del cual se obtuvieron las ecuaciones de campo para la métrica de Friedmann-Lemaître-Robertson-Walker junto con algunas soluciones. Fue usado el procedimiento de compactificación RS sobre la gravedad EGB en 5D, cuyo resultado fue la acción de gravedad de EH en 4D con constante cosmológica. Dicho resultado nos permitió escribir la constante cosmológica Λ4D en términos del par (rc,Λ5D), de lo cual especulamos que Λ4D tiene su origen en el radio de compactificación rc y en la constante cosmológica de la quinta dimensión Λ5D. Aplicando la compactificación de RS sobre la gravedad AdS-ChS fue encontrado gravedad de EH en 4D con constante cosmológica, a partir de la cual fue obtenido Λ4D en términos de rc, que nos lleva a la interpretación del parámetro l como el tamaño del universo. Por último empleamos la compactificación RS sobre gravedad de EChS en 5D, lo que nos condujo a una acción para una gravedad tenso-escalar en 4D que incluye un término de GB, esta acción corresponde a un caso particular de la teoría de Horndeski, en concreto al Lagrangiano (48) de (24).

Published: August 2023

Coniophora olivacea has been traditionally considered as an important decay agent of building timbers of broadleaf and conifer woods, and causes significant damage on doors, window frames and other wood structures exposed to the environment. A more restricted role as tree pathogen has been also reported in cold climates. Studies of the predicted distribution of potentially invasive species are a useful tool to focus management efforts. Maximum-Entropy models allow predictions based on climatic and altitudinal layers as well as on previous data on the occurrence of species. The aim of this work is to report the presence of this wood decay fungus for the first time in Patagonia, and also to predict the potential spread pattern of this species using Maximum-Entropy.

Authors: Imran Muhammad , Almusharraf Norah
Published: August 2023

This study examines the role of ChatGPT as a writing assistant in academia through a systematic literature review of the 30 most relevant articles. Since its release in November 2022, ChatGPT has become the most debated topic among scholars and is also being used by many users from different fields. Many articles, reviews, blogs, and opinion essays have been published in which the potential role of ChatGPT as a writing assistant is discussed. For this systematic review, 550 articles published six months after ChatGPT’s release (December 2022 to May 2023) were collected based on specific keywords, and the final 30 most relevant articles were finalized through PRISMA flowchart. The analyzed literature identifies different opinions and scenarios associated with using ChatGPT as a writing assistant and how to interact with it. Findings show that artificial intelligence (AI) in education is a part of the ongoing development process, and its latest chatbot, ChatGPT is a part of it. Therefore, the education process, particularly academic writing, has both opportunities and challenges in adopting ChatGPT as a writing assistant. The need is to understand its role as an aid and facilitator for both the learners and instructors, as chatbots are relatively beneficial devices to facilitate, create ease and support the academic process. However, academia should revisit and update students’ and teachers’ training, policies, and assessment ways in writing courses for academic integrity and originality, like plagiarism issues, AI-generated assignments, online/home-based exams, and auto-correction challenges.

Quality in Education: Ascertaining the Use of Rubrics for Successful Implementation of OBE at the Tertiary Level in Bangladesh
Authors: Farzana Tasnia , Ilahi Adil
Published: August 2023

This article highlights the potential of rubrics as tools for effective assessment in education by encouraging students to pursue high-quality education, assessing students in ways other than traditional testing, and fostering outcome-based education. It highlights the importance of quantitative research for data gathering and analysis, as well as the use of statistical applications like SPSS for data analysis in educational research. The study examines various types of rubrics and their components to create a full rubric for classroom effectiveness. It also provides literature on appropriate rubric usage for students and teachers, as well as rubric researchers. The findings suggest that a nationwide database of discipline-specific rubrics is necessary for preserving and advancing standards in technical and higher education. A guidelines handbook should be developed before employing rubrics. Implementing rubrics at elementary and secondary levels is essential for students to advance to higher education, as they may be exposed to unprepared OBE approaches in cities with inadequate communication and technology skills. The Ministry of Higher Education should determine teaching obligations and responsibilities, and universities should implement rubrics immediately and emphasise them. The findings are relevant to both students and teachers, emphasising the importance of user perception, rubric design, and intended use in determining the usefulness of rubrics in raising student performance. By optimising variables based on trustworthy data and knowledge of the intended educational context, educators can maximise students' learning opportunities.
Systematic Review in Population-Based General Understanding Surveys of Stroke Perception, Potential Risks, Treatments, and Perspectives for a Correlative Study on Public Awareness Between Different Age Groups and their Lifestyles
Authors: Pattanakul Nathakorn , Yasri Pratchayapong
Published: August 2023

Background: Stroke is a major public health concern that may affect a patient's physical performance and ability to perform fundamental daily duties. Understanding the fundamentals of stroke is crucial for lowering mortality and disability rates among patients, as it allows for the preparation of a rapid and effective treatment and the comprehension of the therapy and treatment process following a stroke. Methods: A survey was distributed to 122 individuals, including 24.6% of high school pupils (12-17), 25.4% of young adults (18-25), 16.4% of adults (26-40), and 33.6% of middle-aged adults (41-60). After completion of data gathering, descriptive analysis was carried out. Results: the outcomes revealed that most participants scored higher on the general comprehension questionnaires than on the technical section. Notably, the level of comprehension of middle-aged adults (x = 9.50) appeared to be the highest. Moreover, those with direct experience with stroke or direct contact with stroke patients had a greater understanding of the disease and its treatment (x = 9.05, p = 0.08) than those without such experience/contact (x = 8.00, p = 0.08). Nevertheless, according to statistical analysis, there was a positive correlation between the age range of participants and their disease awareness. However, the self-care conducted was mostly found in adolescence. Discussion: Therefore, it is necessary for government organizations to encourage awareness and education about fundamental treatments that can assist individuals in avoiding possible risk factors by implementing the FAST guideline simultaneously with a public education effort on stroke response. The greater the number of individuals who comprehend the method for coping with the disease, the greater their protection against the disease.
How to Create Contour Maps for Geochemical Data Visualization
Authors: Valls Ricardo A.
Published: August 2023

As a geologist, the analysis of complex datasets obtained from geochemical sampling is a crucial aspect of identifying anomalies and potential mineralization targets. However, presenting the data in tabular form does not effectively reveal visual patterns. To overcome this limitation, contour maps can be utilized to transform sample values into continuous color-coded surfaces. This transformation allows for the visualization of subtle trends, making it easier to identify promising areas for further sampling and drilling. Contour maps serve as powerful tools for analyzing and interpreting spatial patterns in geochemical data, ultimately offering valuable insights for mineral exploration and environmental analysis.

In the process of examining and deciding cases, environmental judges need materials related to the environment, especially studies of environmental decisions. The study of environmental decisions opens up space for discourse on legal challenges and findings in environmental cases. One of the challenges faced in environmental cases is the inconsistency of decisions that will affect the granting of rights related to the environment to the wider community. Furthermore, the study of environmental decisions highlights issues that are very important in examining environmental cases, such as scientific evidence on environmental damage due to forest fires, industrial activities, mining activities, and others. The objectives to be achieved in this research are to know and analyze substantial aspects to procedural aspects of environmental law, such as the issue of imposing criminal penalties for corporate management, scientific evidence, environmental permits, application of strict liability, citizen lawsuits, issues of environmental case management and the placement of environmental judges. This research is legal research with the type of research that is normative research. Cases that go to court and are registered as environmental cases do not entirely contain legal substances related to the environment. There were many cases registered with the "LH" register whose legal substance was not directly related to the environment, namely criminal cases regulated in the Oil and Gas Law and cases of corruption in the Oil and Gas sector.

Published: August 2023

Individuals with acute disseminated encephalomyelitis (ADEM) can experience persistent cognitive deficits and psychopathology, which significantly interferes with daily functioning and quality of life. Here, we review the current literature to characterise the cognitive and psychological sequelae, suggest avenues for further research, and discuss the implications for clinical practice. Overall, research on this topic is largely limited to the paediatric population. The current evidence demonstrates persistent cognitive deficits in attention and information processing speed, as well as elevated symptoms of depression and anxiety. Results are mixed for executive functions and memory, while language and visuospatial functions are relatively undisturbed.
Effectiveness of interventions for changing more than one behavior at a time to manage chronic conditions: A systematic review and meta-analysis

Published: August 2023

Background: Health behaviors play a significant role in chronic disease management. Rather than being independent of one another, health behaviors often co-occur, suggesting that targeting more than one health behavior in an intervention has the potential to be more effective in promoting better health outcomes. Purpose: We aimed to conduct a systematic review and meta-analysis of randomized trials of interventions that target more than one behavior to examine the effectiveness of multiple health behavior change interventions in patients with chronic conditions.Methods: Five electronic databases (Web of Science, PubMed, CINAHL, EMBASE and Cochrane) were systematically searched in November 2023, and studies included in previous reviews were also consulted. We included randomized trials of interventions aiming to change more than one health behavior in individuals with chronic conditions. Two independent reviewers screened and extracted data, and used Cochrane’s Risk of Bias 2 tool. Meta-analyses were conducted to estimate the effects of interventions on change of health behaviors. Results were presented as Cohen’s d for continuous data, and risk ratio for dichotomous data. Results: Sixty-one studies were included spanning a range of chronic diseases: cardiovascular (k = 25), type 2 diabetes (k = 15), hypertension (k = 10), cancer (k = 7), multiple conditions (k = 3). Most interventions aimed to change more than one behavior simultaneously (rather than in sequence) and most targeted three particular behaviors at once: ‘physical activity, diet and smoking’ (k = 20). Meta-analysis of 43 eligible studies showed for continuous data (k = 29) a small to substantial positive effect on behavior change for all health behaviors (d = .081 to 2.003) except for smoking (d = -.019). For dichotomous data (k = 23) all analyses showed positive effects of targeting more than one behavior on all behaviors (RR = 1.026 to 2.247). Conclusions: Targeting more than one behavior at a time is effective in chronic disease management and more research should be directed into developing the science of multiple behavior change.
fractalRegression: An R package for multiscale regression and fractal analyses
Authors: Likens Aaron , Wiltshire Travis J.
Published: August 2023

Time series data from scientific fields as diverse as astrophysics, economics, human movement science, and neuroscience all exhibit fractal properties. That is, these time series often exhibit self-similarity and long-range correlations. This `fractalRegression` package implements a number of univariate and bivariate time series tools appropriate for analyzing noisy data exhibiting these properties. These methods, especially the bivariate tools [@kristoufekDetrendedFluctuationAnalysis2015; @likensStatisticalPropertiesMultiscale2019] have yet to be implemented in an open source and complete package for the R Statistical Software environment. As both practitioners and developers of these methods, we expect these tools will be of interest to a wide audience of scientists who use R, especially those from fields such as the human movement, cognitive, and other behavioral sciences. The algorithms have been developed in C++ using the popular Rcpp [@eddelbuettelRcppSeamlessIntegration2011] and RcppArmadillo [@eddelbuettelRcppArmadilloAcceleratingHighperformance2014] packages. The result is a collection of efficient functions that perform well even on long time series (e.g., $\geq$ 10,000 data points). In this work, we introduce the package, each of the functions, and give examples of their use as well as issues to consider to correctly use these methods.
Making Wakefield Warranted: The Hierarchy of Healing Harm and Discerning Dysfunction
Authors: Hunt Adam
Published: August 2023

The definition of medical ‘disorder’ is a matter of longstanding debate. A leading account is Jerome Wakefield’s ‘harmful dysfunction’ analysis, a hybrid model which merges normative and naturalist elements to propose disorder exists in cases of concurrent harm (value-defined) and dysfunction (defined evolutionarily). Despite significant impact in academia, this has so far failed to affect mainstream medical treatment or discourse, with a major criticism being that this definition doesn’t correctly capture all conditions of medical relevance or actual medical ideals. This paper provides a supplementary structural nuance to better reflect how medical treatment and terminology incorporate naturalistic facts. I argue that Wakefield is right in utilising a hybrid model incorporating naturalism and normativity. However, in understanding how medicine is directed, making the normative and naturalistic equally necessary is problematic, because the imperatives of naturalism and normativity directly impede each other; norms seek to help those who need help, naturalism concentrates on objective facts, but neither can be fulfilled as a coherent goal of medical treatment when combined as equally necessary. Instead, I propose a hierarchical harmful dysfunction model better reflects current medical ideals, where normative values are necessary and sufficient conditions to prescribe treatment, whilst naturalistic knowledge plays a role informing those normative values. This accounts for the edge cases and practise of medicine not fully captured in Wakefield’s account of ‘disorder’.
Mindfulness meditators’ brains show an acceptance of death which predicts positively-valenced meditative self-dissolution experiences

We recently showed using a magnetoencephalogram visual mismatch-response paradigm that self-specific prediction-based neural mechanisms shield the self from existential threat by attributing death to the ‘other’. Here we test the pre-registered hypothesis that mindfulness meditation is associated with a reduction in the brain’s defensiveness towards mortality. Additionally, we examine putative links between death acceptance and the phenomenology of meditative self-dissolution. Thirty-eight meditators pooled from a previous project investigating self-dissolution neurophenomenology underwent the task. The findings indicated that meditators’ brains responded to the coupling of death and self-stimuli in a manner indicating acceptance rather than denial, and corresponding to increased well-being. Additionally, death acceptance predicted positively-valenced meditation-induced self-dissolution experiences, thus shedding light on possible mechanisms underlying wholesome vs. pathological disruptions to self-consciousness. Overall, these findings provide empirical support for the hypothesis that the neural mechanisms underlying the human tendency to avoid death are not hard-wired but are amenable to mental training.
