Authors: Lauer Luisa , Peschel Markus
Published: January 2023

Die Technologie Augmented Reality (AR) eröffnet durch Anreicherung der realen Welt mit virtuellen Informationen innovative pädagogisch-didaktische Gestaltungsmöglichkeiten in Lehr-Lern-Situationen. Insbesondere im Sachunterricht der Primarstufe besteht derzeit noch ein erhebliches Desiderat zur Erforschung des pädagogisch-didaktischen Potenzials des Einsatzes von AR sowie grundsätzlich zur Konzeption und Implementation entsprechender AR-Lehr-Lern-Tools. Ziel der in diesem Beitrag beschriebenen Studie ist die Erlangung grundlegender Erkenntnisse zur Einschätzung der «Pedagogical Usability» eines AR-Lehr-Lern-Tools für den naturwissenschaftlich-orientierten Sachunterricht durch Grundschullehrpersonen. Diese durch Befragung von Grundschullehrpersonen gewonnenen Einschätzungen wurden in einem qualitativen Design mittels eines leitfadengestützten Interviews erfasst und durch eine strukturierende qualitative Inhaltsanalyse ausgewertet. Insgesamt zeigt sich, dass das evaluierte AR-Lehr-Lern-Tool einige Teilaspekte der Pedagogical Usability aus Sicht der Lehrpersonen erfüllt (z. B. «Motivation» und «Student Control») und in anderen Teilen noch verbessert werden könnte (z. B. bzgl. «Applicability» und «Feedback»). Auffallend ist auch, dass die Lehrpersonen die pädagogisch-didaktischen Vorteile von AR nicht oder kaum erkennen und die Unterschiede zwischen verschiedenen AR-Technologien auch nur teilweise benennen oder erkennen können. Die Ergebnisse stellen eine erste Grundlage für weitere Untersuchungen zur Rolle der Lehrperson bei der Entwicklung, Evaluation und Implementierung hoch innovativer, technologiegestützter Lehr-Lern-Tools sowie für die Erforschung des pädagogisch-didaktischen Potenzials von AR zu weiteren Themen des Sachunterrichts dar.
Melting and melt segregation processes controlling granitic melt composition
Authors: Yu Yang , Huang Xiao-Long , Weinberg Roberto F. , Sun Min , He Peng-Li , Zhang Le
Published: January 2023

Several important processes in the petrogenesis of granite are still debated due to a poor understanding of complex interactions between minerals during the melting and melt segregation processes. To promote an improved understanding of the mineral-melt relationships, we present a systematic petrographic and geochemical analysis for melanosome and leucosome samples from the Triassic Jindong migmatite, South China. Petrographic observations and zircon U-Pb geochronology indicate that the Jindong migmatite was formed through water-fluxed melting of the Early Paleozoic gneissic granite (437 ± 2 Ma) during the Triassic (238 ± 1 Ma), with the production of melt dominated by the breakdown of K-feldspar, plagioclase, and quartz. The Jindong leucosomes may be divided into lenticular and net-structured types. Muscovite, plagioclase, and K-feldspar in the net-structured leucosome show higher Rb and much lower Ba and Sr contents than those in the lenticular leucosome. This may be attributed to the elevation of Rb and decreasing Ba and Sr abundances in melts during the segregation process due to early fractional crystallization of K-feldspar and plagioclase. These leucosomes show negative correlation between εNd(t) and P2O5, reflecting increasing dissolution of low-εNd(t) apatite during the melting process. The continuous dissolution of apatite caused saturation of monazite and xenotime in melt, resulting in the growth of monazite and xenotime around apatite in the melanosome. This process led to a sharp decrease of Th, Y, and REE with increasing P2O5 in the leucosome samples. This complex interplay of accessory mineral reactions in the source impacts REE geochemistry and Nd isotope ratios of granites. As the granites worldwide exhibit similar compositional and isotopic patterns to the Jindong leucosomes, we suggest that both the melting and melt segregation processes strongly control the granitic melt compositions.

Authors: Moses Okponmwense , Agbonsalo Osaretin Festus
Published: January 2023

Remediation is vital in advancing the agriculture yield and decreasing the hazard of food poisoning in contaminated soil. The aim of this study was to remediate lead and cadmium contaminated soil from Evbareke spare parts market using surface modified calcium oxide nanoparticle (SMCON). Soil samples were collected from Evbareke spare parts market, Benin City, Edo state Nigeria, using quadrant sampling method at the depth of 0-15cm using soil auger. The soil samples obtained were physicochemically and geochemically characterized. The SMCON was synthesized and characterized using Fourier Transform-Infra Red, Scanning electron spectroscopy and x-ray diffraction. A leaching experiment was carried out to authenticate the immobilization efficiency and capacity of SMCON on the lead and cadmium in the contaminated soil. The SMCON efficiency for lead and cadmium immobilization in the contaminated soil increased with increase in immobilizer up to the optimum 4% of SMCON in contaminated soil for lead and ≤1% of SMCON for cadmium. Likewise, the immobilization capacity of SMCON in the contaminated soil also revealed that more of lead and cadmium were immobilized as SMCON content in the contaminated soil mixture increased, thereby disallowing leaching of lead and cadmium from the contaminated soil. The SMCON effectively decreased the lead and cadmium in the soil by in situ adsorption, ion exchange and complexation mechanism thus reducing its accessibility for uptake by plants and its transmission to man and animals.
Quantitative Relationships Between Structure and Activity of Gamma-Carboline Derivative Compounds as Anti-Bovine Viral Diarrhea Virus (BVDV) Using Semi-Empirical AM1 Method
Authors: Hafshah Mutista , Firdaus Irvan Maulana , Suratno Suratno
Published: January 2023

This research aims to study the quantitative structure and activity relationship (QSAR) of gamma-carboline derivative compounds as anti-BVDV agents to get an equation that can predict the value of the anti-BVDV activity of gamma-carboline derived compounds. The research material is experimental EC50 data that convert to anti-BVDB activity. 14 gamma-carboline derivative compounds are divided into 2 groups, namely, 11 fitting compounds and 3 test compounds. QSAR analysis is based on multilinear regression calculations of the fitting compound by plotting the EC50 log as the dependent variable and the descriptor as the independent variable. The used descriptors are atomic net charge (q) and dipole moment (µ), which are involved in calculations using the AM1 semiempirical quantum mechanics method. In addition, the partition coefficient of n-octanol/water (Log P), molecular polarizability (α), molecular weight (BM), Van Der Waals surface area (A vdw), Van Der Waals volume (V vdw), and index of refraction (RD) are obtained from QSAR properties. The resulting QSAR equation is: Log pEC50 = -48.670 – 124.801 (qC11) – 12.661 (α) – 0.918 (µ) – 0.876 (RD) – 0.999 (Log P) + 1.863 (BM) + 0.043 (V vdw) with n = 14; r = 0.937; r2 = 0.878; SD = 0.244; Fcount/Ftable = 1.466; PRESS = 0.749; Sig. = 0.02 This equation can be used as an initial guide for designing the structure of new compounds of the gamma-carboline class by considering some of the most influential descriptors. Consequentially, new compounds can be designed that have a smaller predicted EC50 value than the known compounds derived from gamma-carboline.

Authors: Fitriani Ika Nur , Sholahudin Muhammad , Zikri Adi Tiara
Published: January 2023

QSAR analysis from derivative compounds of 1,8-naphthalimide-4-aminoquinoline has been carried out with the aim of knowing the quantitative relationship between structure and activity based on the log IC50 value. The modelling was made with two dimensions and geometric optimization is carried out. The AM1 semi-empirical method was used to optimize the geometry of the total energy of 25 compounds. The descriptors in the QSAR calculation were dipole moment, atomic net charge, ELUMO, EHOMO, SAG, SAA, hydration energy, polarizability, and log P. The descriptors were used to find quantitative equations of the relationship between the structure and antimalarial activity.

Published: January 2023

The accelerated development of e-commerce has been a concern for business people. Business people should be able to gain customer interest in a variety of ways so that their companies can compete with others.  Analyzing click-flow data will help organizations or firms assess customer loyalty, provide advertising privileges, and develop marketing strategies through user interests. By understanding consumer preferences, clickstream data analysis may be used to determine who is participating, assist companies in evaluating customer contentment, boost productivity, and design marketing strategies. This research was performed by defining experimental user interests using Dynamic Mining and Page Interest Estimation methods. The findings of this analysis, using three algorithms at the pattern discovery page, demonstrated that the Decision Tree method excelled in both methods. It indicated that the operational performance of the Decision Tree performed well in the assessment of user interests with two different approaches. The findings of this experiment can be used as a proposal for researching the field of web usage mining, collaborating with other approaches to achieve higher accuracy values.
Towards Erlang-based ABS Microservices Framework for Software Product Line Development
Authors: Novrialdi Adrika , Adianto Daya , Rosyida Aulia , Bagaskara Priambudi Lintang , Azurat Ade
Published: January 2023

The current widely used software system can be categorised as a large or very large decentralised control system with various requirements and continuous interchangeable elements. This characteristic leads to a need to control the variability to manage such systems. Software Product Line Engineering (SPLE) is one of the approaches that can manage the variability by developing sets of products. However, there is a need for support tools for development with software product line engineering. One language that supports the SPLE process is Abstract Behavioral Specification (ABS). Some SPLE research has used ABS to create frameworks that support the SPLE process. ABS Microservices is one research that utilises ABS to create a web framework that supports the SPLE process. This framework uses ABS to generate Java-based applications. The research interest in the web application is driven by the fact that it is one of the software types widely used by organisations and serves as the primary support of their business. Microservices are highly interoperable, thus enabling researchers to integrate different technology from other research. However, there is a need for renewal to the ABS Microservices framework. There is a need for more variants of SPLE-enabled frameworks that use more programming language as a specific programming language has its strength and weakness. Deprecation of the Java backend of the ABS opens a new exploration of another web framework that uses other ABS backend languages. We present the ABS microservices web framework based on Erlang OTP. We choose Erlang because it promises more efficient resource usage and the Erlang backend is one of the ABS backends with the most available features. This research aims to create an entry point for ABS Microservices to support more language. This research shows that the Erlang variant of ABS Microservices has less resource usage than the Java variant. Hence, this promises more options to develop product lines using ABS Microservices.
UML Transformation to Java-based Software Product Lines
Authors: Waluyo Falah Prasetyo , Setyautami Maya Retno Ayu , Azurat Ade
Published: January 2023

Software product line engineering (SPLE) is an emerging approach that enables variability management in software development. SPLE offers tremendous benefits, but lack of tool support becomes a barrier in the adoption of SPLE. Variability modules for Java (VMJ) is an implementation approach that is defined based on the variability modules (VM) concept to support SPLE. VMJ combines Java modules system and design patterns that are commonly used by software developers. VMJ is accompanied by a UML profile, called UML-VM profile, which extends UML notation to model variability in the UML diagram. UML-VM diagram is used to model the problem domain, and VMJ is used in the domain implementation. In this research, we design a model transformation from Unified Modeling Language (UML) diagram into VMJ. The transformation rules are defined based on the UML-VM profile and implemented in the Eclipse Acceleo model to text transformation. As a result, a UML diagram can be transformed automatically into Java-based software product lines. The transformation tool is evaluated using a case study by comparing the generated code and the actual implementation.
Optimization of 2D-CNN Setting for the classification of covid disease using Lung CT Scan
Authors: Kirana Kartika Candra , Wibawanto Slamet , Hamdan Ahmad , Hidayat Wahyu nur
Published: January 2023

RT-PCR is considered the best diagnostic tool. Previous studies have demonstrated the reliability of CNN in classifying classifications, but CNN requires a lot of training data. Meanwhile, at the CT Scan clinic, patients are limited. Therefore, exploration of 2D-CNN settings is proposed to optimize CNN performance on limited data. We compare: (1) activation models, (2) output shapes per layer, (3) dropout layers, and (4) early stopping values. The test results show that RELU activation is better than Sigmoid. Rescaling (128x128) is better for scala (64x64) and (256x256) which affects the output shape model of each layer. In this learning stage, the use of dropouts in the CNN architecture achieves robust accuracy than the architecture that ignores dropouts. The use of 15 early stoppings is better than other values compared. 20 images of pneumonia and 20 images of covid have been tested using the proposed method and achieved 87.50% accuracy, 80.00% precision, 100% recall, and 99.89% F1-Score. Our method is superior to the the comparison method in terms of accuracy, precision, recall, and f1-score, which achieves 85%, 70%, 100%, and 82.35%, respectively.

Neste artigo objetiva-se compreender, por um esforço teórico, como os saberes de mulheres bruxas é adquirido e como esses ensinamentos se perpetuam no tempo. Em diálogo com noções feministas, principalmente decoloniais, evidenciamos pistas sobre a relação entre grupos de mulheres consideradas bruxas e a natureza. Destacamos ainda como os marcadores de gênero, raça e classe se conectam às práticas de violência que se perenizam contra as bruxas, fomentando práticas contra a existência de corpos específicos; e colocando em evidência a prevalência de uma “caça às bruxas”, ainda no cenário atual. Denota-se ainda os processos de resistências desse grupo de mulheres às tentativas de extermínio, por meio da perpetuação de seus saberes.
E possível decolonizar as políticas públicas educacionais promotoras de jornada ampliada para o ensino médio?
Authors: Pereira Leite Maria Eduarda
Published: January 2023

Resumo: Este artigo tem como objetivo visualizar possibilidades emancipatórias contidas na Educação Integral, tendo como referência a perspectiva decolonial, afim de propor um diálogo junto a pesquisas em andamento no campo das políticas públicas educacionais promotoras da educação de tempo ampliado para o ensino médio. No contexto educacional brasileiro, a educação (de tempo) integral parece se inserir em um caso onde a colonialidade ainda permanece contribuindo para a reprodução das diversas formas de desigualdade, com narrativas que ainda tendem a privilegiar teorias e pensamentos eurocêntricos. Por isso, sustenta-se neste artigo que é preciso além de questionar e fazer a crítica a estas concepções, que informam e orientam as práticas de extensão da jornada escolar construídas no Brasil, também visualizar possibilidades que desenvolvam uma agenda de Educação (em tempo) Integral que considere as variadas dimensões do desenvolvimento humano, como também reconheça os processos colonização e seus efeitos de subalternização sobre os sujeitos coletivos e individuais reclamando o comprometimento da educação escolar com esta realidade.

Abordagem do sentido nos estudos semânticos e pragmáticos: uma análise de charges e tirinhas
Authors: Karlo-Gomes Geam , Alvares Claudia Assad
Published: January 2023

Este texto busca evidenciar o papel de dois domínios linguísticos fundamentais no estudo da linguagem: a semântica e a pragmática, concomitantes na determinação dos estudos que permeiam a interação comunicativa. Parte-se do princípio de que, além da inteligibilidade das frases, há outros aspectos que integram o dito (semântica) e a leitura do que é dito (pragmática); com a virada pragmática, o uso, o contexto, a situação de discurso e os falantes redefinem os estudos linguísticos. O objetivo deste texto é mostrar que a semântica e a pragmática se imbricam na constituição dos estudos da linguagem. Procuramos demonstrar como isso acontece por meio da análise de charges e tirinhas.
O comportamento da vogal média anterior átona /E/ no português falado em Passo Fundo (RS)
Authors: Vieira dos Santos Heric Gabriel , Gutierres Athany
Published: January 2023

O objetivo deste trabalho é investigar o comportamento da vogal média anterior átona /e/ em sílabas abertas (ado.te) ou fechadas (es.ses) em posição postônica final no Português Brasileiro (PB) falado em Passo Fundo, Rio Grande do Sul (RS). No Brasil, a elevação (/e/ à [i]) é praticamente categórica nesses casos (adot/e/ à adot[i]; ess[e]s à ess/i/s), porém, em algumas localidades da região sul do país, principalmente naquelas do interior, é possível notar que há variação (GUTIERRES; BATTISTI, 2020; VIEIRA, 2014; VIEIRA, 2010; GUZZO, 2012; 2010). Para verificar o comportamento da vogal /e/ nesse contexto, foi realizada uma análise estatística de regressão logística (modelo de efeitos mistos) com dados de fala de 20 informantes nascidos e residentes em Passo Fundo. Foram controladas cinco variáveis sociais (faixa etária, gênero, escolaridade, ocupação e região de residência) e cinco linguísticas (contexto fonológico precedente e seguinte, qualidade da vogal da sílaba tônica precedente, número de sílabas e tipo de palavra). A aplicação da regra variável (elevação) ocorreu em 17% (110/630) da amostra, e a não aplicação (preservação da vogal átona), em 83% (520/630). Na fala passo-fundense, a elevação é favorecida socialmente pelas variáveis gênero, escolaridade e profissão; e gramaticalmente pelas variáveis contexto fonológico precedente, número de sílabas e tipo de palavra. O resultado da análise evidencia o efeito de fatores externos sobre a gramática e está consoante à literatura no que diz respeito às variedades de PB faladas no interior: há variação entre elevação e preservação de /e/, sendo essa última a preferência na comunidade.

Também foi possível evidenciar a relação entre pressupostos da Linguística Cognitiva e da História das Ideias Linguísticas.
Synthesis, Molecular Docking, and Anticancer Activity of N-Heteroaryl
Substituted Flavon Derivatives
Authors: Fegade Bharti Sachin , Jadhav Shailaja
Published: January 2023

Background:

Flavones are potential anticancer agents that act by different mechanisms and
have multiple targets to exert anticancer effects. Nitrogen-containing heterocyclic rings have remarkable
chemical characteristics as well as a wide range of biological activities. Substitution of the N-heterocyclic
ring on the flavon structure may potentiate its anticancer effect.

Objective:

A series of flavon derivatives with an N-heteroaryl ring at the 4' position of the B ring of flavon
were designed, prepared, and evaluated for anticancer activity.

Methods:

Different flavon derivatives were created by cyclizing chalcones, and chalcones were synthesized
by Claisen-Schmidt condensation of substituted aldehydes and 2-hydroxyacetophenone. Structures
of all compounds were confirmed by 1HNMR, 13CNMR, FTIR, and MS spectra. Molecular docking was
used to study the binding interactions of the synthesized compounds with the multiple targets ER-α,
EGFR, and VEGFR-2. Anticancer activity was evaluated by Brine shrimp assay, MTT assay, and SRB
assay on breast cancer (MCF-7, MDA-MB-231, and MDA-MB-468) and cervical cancer (HeLa). An
apoptosis study was carried out on MCF-7 cell lines for the active compounds.

Results:

Among all compounds, 6c and 5f showed potent growth inhibition of ER-positive breast cancer
cell lines. Compounds 5b, 5c, 5g, and 6f displayed good anticancer activity against cervical cancer. In
triple-negative breast cancer cell lines, compounds 5c, 6b, and 6c showed remarkable anticancer activity.
The potent flavones identified against breast cancer cell lines were 5f and 6c. Anticancer study results
were analogous to the results obtained by the molecular docking study.

Conclusion:

This study offers a viable reference point for improving the design of flavon-incorporated Nheterocyclic
ring derivatives as anticancer compounds.
Experimental Study and Modeling of Solid-liquid Equilibrium for Binary and Ternary Pharmaceutical and Food Systems
Authors: Bitchikh Karima , Nabil Smakghi , Abdeslam-Hassen Meniai
Published: January 2023

Background:

The experimental measurement of the solubility of a solute in a given solvent is a difficult task; hence, there is a need for reliable thermodynamic models for its prediction. However, these models require either molecular or group interaction parameters, which are not always available.

Objective:

The objective of the present study is to measure experimentally the solubility of different solutes in solvents selected from pharmaceutical or food fields on the basis that not all the required model interaction parameters are available to use the obtained experimental data for their determination.

Methods:

The experimental study of solid-liquid equilibrium for chosen binary and ternary systems at different temperatures was carried out using differential scanning calorimetry to determine the essential thermophysical properties like melting temperature and enthalpy. The modeling of these phase equilibrium data was performed using thermodynamic models like Random Two Liquids (NRTL) and Universal Functional Activity Coefficient (UNIFAC).

The required NRTL interaction parameters were determined by minimizing a well-defined objective function using the simplex method.

Results:

The solubilities of the solutes in the different considered solvents at different temperatures obtained experimentally provided the required NRTL molecular interaction parameters. Solute solubilities were obtained using NRTL, UNIFAC, and ideal models. The comparisons showed an excellent agreement between the experimental values and the NRTL results, contrary to UNIFAC and ideal case models.

Conclusion:

This study shows the importance of thermodynamic modeling to predict solubility data that may be difficult, time-consuming, and costly to obtain experimentally.

Published: January 2023

Concrete is a widely used material for construction therefore, it is necessary to identify materials that are economical, environmentally friendly, easily available, and prevention of environmental damage while sourcing the materials, hence the aim of this study. The current study’s objective is to have a comprehensive study on the previous research identifying the effects of chipped rubber as concrete coarse aggregate and the compressive strength (fc) of the concrete and to identify areas of relevance for better sustainability to reduce the rate of waste rubber and degradation of the environment. To achieve the objectives of this study, a review of previous research works was conducted and analyzed. A comprehensive study on the fc of chipped rubber coarse aggregate concrete (RCAC) was studied by reviewing previous research. The addition of chipped rubber in concrete to a specific ratio can enhance or reduce the concrete fc. But a reduction in the rubber concrete’s fc can be seen when the rubber content ratio exceeded 20%. When the chipped tyre rubber is treated with coupling agents, an increase in the concrete fc can be seen. The use of chipped rubber in concrete production reduces environmental degradation and proves as a step toward the sustainable development goal (SDG). Chipped RCAC mixtures are weaker than regular concrete mixtures. RCAC on the other hand is more ductile and has a better energy dissipation pattern. The fc of concrete was found to be affected by substituting concrete aggregates with rubber.

Authors: Pachiou Aspasia , Roussou Ilia , Kourtis Stefanos
Published: January 2023

Background:

Dental implants offer many viable clinical solutions, but there are patients when they cannot be chosen as the optimal plan. Conventional removable prostheses still come up as a functional option, and several techniques have been developed so that their appearance can be esthetically enhanced and, in certain circumstances, even customized.

Case report:

This paper presents a clinical case where new conventional dentures were manufactured for both jaws. The patient was complaining about the “artificial” appearance of the pre-existing restorations and was also diagnosed with depression, which was an extra challenge to be dealt with. Attention was also given to individualizing the esthetic performance utilizing materials and techniques for the characterization and customization of the dentures for a natural-like result, in accordance with all the clinical factors that influence the restoration in edentulous patients.

Conclusion:

As shown in the presented case, complete dentures remain a viable treatment plan. Especially via the process of characterization and customization, higher patient satisfaction and easier acceptance can be achieved.

Quality of Information in Gallstone Disease Videos on TikTok: Cross-sectional Study
Authors: Sun Fei , Zheng Shusen , Wu Jian
Published: January 2023

Background

TikTok was an important channel for consumers to access and adopt health information. But the quality of health content in TikTok remains underinvestigated.

Objective

Our study aimed to identify upload sources, contents, and feature information of gallstone disease videos on TikTok and further evaluated the factors related to video quality.

Methods

We investigated the first 100 gallstone-related videos on TikTok and analyzed these videos’ upload sources, content, and characteristics. The quality of videos was evaluated using quantitative scoring tools such as DISCERN instrument, the Journal of American Medical Association (JAMA) benchmark criteria, and Global Quality Scores (GQS). Moreover, the correlation between video quality and video characteristics, including duration, likes, comments, and shares, was further investigated.

Results

According to video sources, 81% of the videos were posted by doctors. Furthermore, disease knowledge was the most dominant video content, accounting for 56% of all the videos. The mean DISCERN, JAMA, and GQS scores of all 100 videos are 39.61 (SD 11.36), 2.00 (SD 0.40), and 2.76 (SD 0.95), respectively. According to DISCERN and GQS, gallstone-related videos’ quality score on TikTok is not high, mainly at fair (43/100, 43%,) and moderate (46/100, 46%). The total DISCERN scores of doctors were significantly higher than that of individuals and news agencies, surgery techniques were significantly higher than lifestyle and news, and disease knowledge was significantly higher than news, respectively. DISCERN scores and video duration were positively correlated. Negative correlations were found between DISCERN scores and likes and shares of videos. In GQS analysis, no significant differences were found between groups based on different sources or different contents. JAMA was excluded in the video quality and correlation analysis due to a lack of discrimination and inability to evaluate the video quality accurately.

Conclusions

Although the videos of gallstones on TikTok are mainly provided by doctors and contain disease knowledge, they are of low quality. We found a positive correlation between video duration and video quality. High-quality videos received low attention, and popular videos were of low quality. Medical information on TikTok is currently not rigorous enough to guide patients to make accurate judgments. TikTok was not an appropriate source of knowledge to educate patients due to the low quality and reliability of the information.

Published: January 2023

O lançamento do biogás gerado para atmosfera em aterros sanitários na forma de emissões fugitivas (pela camada de cobertura) é bastante representativo. Dado o elevado potencial do biogás como gás de efeito estufa (GEE), o estudo de diferentes tecnologias de seu aproveitamento para a produção de energia tem sido cada vez mais estudado. Além do aproveitamento do biogás, o emprego de biossistemas (biorrecobrimentos, biofiltros, etc.) em camadas de cobertura visando à otimização do consumo biótico de metano, principal componente do biogás em termos de potencial de aquecimento global, também tem sido amplamente avaliado como sistema complementar na mitigação de GEE. Desta forma, o presente estudo avaliou o desempenho, em termos de eficiência de oxidação de metano, de um biofiltro preenchido com solo convencional do aterro enriquecido com escuma de estação de tratamento de efluentes domésticos. Este biofiltro “melhorado”, com elevado teor de matéria orgânica (»4.5%) na porção superior do leito, foi comparado a um biofiltro “controle”, contendo apenas solo convencional do aterro e, portanto, com baixo teor de matéria orgânica (»0.5%). Ambos os biofiltros foram alimentados com carga de »44 gCH4.m-2.d-1 ao longo de nove campanhas de monitoramento. Parâmetros como concentração de metano no biogás bruto, umidade e temperatura dos leitos biofiltrantes também foram relacionados às eficiências de oxidação de metano. A eficiência média de oxidação de metano no biofiltro melhorado foi de 95.2%, comparativamente ao biofiltro controle (84.7% de eficiência), ratificando a eficácia de escuma de ETE como agregado do solo de camada de cobertura na mitigação de GEE.

In this context, the objective of this research is to propose resilience and sustainability indicators for Panamanian urban housing by considering the effects of climate change through an extensive analysis of the country's vulnerability. Using qualitative processes, validated by national and international professionals, it was possible to characterize resilient and sustainable housing and develop a proposal of 29 indicators that respond to current and future climate change-related impacts: 15 for resilience and 14 for sustainability. Thus, building a simple useful tool to evaluate the resilience and sustainability of urban housing.

Just a New Way to Roll
Authors: Lim Si Wei
Published: January 2023

Just a New Way to Roll follows the story of Hiroya, a Japanese college student on exchange in the United States of America in the mid-80s. There, he embarked on a journey to discover the true meaning of the authenticity in dishes created in ways other than what he was familiar with. Through his experiences with his new friend Dave, he realized that similar food items prepared differently elsewhere did not mean that they were not genuine; instead they were creative variations to suit the local preferences. Hiroya also learned that it was insensitive to judge each dish without ample knowledge of its origins, and what he thought he had grown up eating was in fact an adapted dish from another country. This story explores the subliminal ways of how food forms part of our identity, and how respecting the identity of others is as important as acknowledging our own.
Haiku Seven Gastronomicity
Authors: Kuttan Sanjay
Published: January 2023

Haiku is an unrhymed verse form of Japanese origin having three lines containing usually five, seven, and five syllables respectively, a poem in this form usually having a seasonal reference. I have always been searching for new ways to express myself and my recent collection of Haiku in ‘In One Breath’ was published in 2022. I chose to do seven Haiku to capture the various foods I enjoy covering a myriad of cuisines that reflect a very multicultural Singapore with multinational presence. Not that I am numerologist, but the number seven was particularly interesting because it consisted of the union of the physical (number 4) with the spiritual (number 3), and in Pythagorean numerology the number 7 means spirituality. Furthermore, as an early prime number in the series of positive integers, the number seven has also greatly symbolic associations in religion, mythology, superstition, philosophy and now in poetry as it reflects both the physical and spiritual nature of food. Food that unites and reunites relationships, always prepared with love and respect for the origins of the recipe and respect for the consumer as it becomes one with the body that enjoys its nourishment and teases the senses.

Documentos feitos, garantias desfeitas? A trajetória de registros a partir de uma etnografia documental
Authors: Sales Letícia , Eilbaum Lucia
Published: January 2023

O intuito desse trabalho é compreender como documentos normativos podem ser trabalhados e analisados ao suscitar emaranhados de discursos, categorias, classificações, significados, simbolismos e representações sobre os universos que pretendem regular. A partir da etnografia de documentos, conjugada com etnografias sobre o sistema de justiça criminal, foram resgatados arquivos que tratam do direito à prisão domiciliar para mulheres-mães-presas com filhos de zero a doze anos a fim de analisá-los em conexão, entendendo que são documentos produzidos pelo Estado, a partir de processos decisórios regulados e ritualizados pelo próprio Estado. Dessa forma, foi possível perceber que não só a formulação desses documentos, como também sua aplicabilidade, não é absoluta e universal, mas também carregada de moralidades e sujeita às interpretações singulares a depender da situação.

Background: Low bone mineral density (BMD) is prevalent in
individuals with β-thalassemia which might be related to increased
circulating dickkopf-1 (Dkk-1). These data are limited in α-thalassemia.
Objectives: To evaluate the prevalence of low BMD in
adolescents with non-deletional hemoglobin (Hb) H disease. Additionally,
we aimed to examine the association between serum Dkk-1 concentration
and BMD. Methods: Participant medical records were reviewed.
The lumbar spine (LS) and total body (TB) BMD were measured and
converted into height-adjusted z-scores. Serum Dkk-1, osteocalcin and
C-telopeptide of type-I collagen (CTX) concentrations were also
analyzed. Results: Thirty-seven participants (59% female, 86%
Tanner stage ≥2, 95% regularly transfused) had mean age 14.6 ± 3.2
years, and average pretransfusion Hb and ferritin concentrations of 8.8
± 1.0 g/dL and 958 ± 513 ng/mL, respectively. No participants had
experienced fracture. The prevalence of low LSBMD and TBBMD was 42% and
17%, respectively. LSBMD z-score was lower in males vs. females
(p-value = 0.029). LSBMD and TBBMD z-scores were correlated positively
with BA, Tanner stage, and BMI, and negatively with Dkk-1 (p-values
<0.05). Dkk-1 was correlated positively with history of
delayed puberty, and negatively with transfusion interval (p-values =
0.038). Osteocalcin and CTX did not correlate with BMD or Dkk-1.
Multiple regression analysis showed Dkk-1 inversely associated with
TBBMD z-score adjusting for confounders (p-value = 0.009).
Conclusions: We demonstrated a high prevalence of low BMD in
adolescents with non-deletional Hb H disease. Moreover, Dkk-1 inversely
associated with TBBMD suggesting it may serve as bone biomarker in
thalassemia.

Aims: Studies suggested that drug pricing might be a risk factor for
drug shortage; however, a few provided a quantitative assessment of this
possible causal association. This study aimed to assess whether drug
prices are associated with drug shortage incidents. Methods: This was a
retrospective database analysis study. Drugs with shortage notifications
(one drug per notification) that were sent to the Saudi Food and Drug
Authority (SFDA) from Jan/2017 to Dec/2020 by different stakeholders
were included in the study. For each drug, the foreign-to-Saudi-price
ratio (FTSPR) was calculated (FTSPR= mean international price/Saudi
price). Accordingly, drugs were split into three groups: Group 1 (FTSPR
>1]), Group 2 (FTSPR =1]), and Group 3 (FTSPR
<1]). The primary outcomes were the ratio of mean counts
(mCR) between the three groups with Group 3 chosen as a control group.
The study outcomes were analyzed using a negative binomial regression
model adjusting for the measured confounders. All study analyses were
conducted using RSudio Version 1.2.5033. Results: A total of 900 drugs
were included (Group 1=348, Group 2=345, Group 3=209). The mean count of
Group 1 higher was higher than Group 3 (mCR: 1.88; 95% confidence
interval [CI] 1.24 to 2.83), while and mean counts of Group 2 vs.
Group 3 were comparable (mCR: 1.39; 95%CI 0.92 to 2.09). Discussion:
The results of our study showed that shortage was associated with drugs
that are more expensive outside Saudi Arabia. Additional international
studies are needed to explore this causal association.
