Gas chromatography coupled to mass spectrometry (GC-MS) has been widely used, and along with other methodologies such as derivatization, is a powerful tool to analyze phytocompounds, including cuticular wax components. The loss of structural information upon fragmentation of waxes makes it difficult to interpret and identify the GC-MS mass spectra of these compounds with the traditional methods, as digital libraries. Therefore, as a new complementary alternative to traditional methods of identifying aliphatic acyclic lipids based on mass spectra, we present the new software WaxAlly in this technical note. WaxAlly is a new software created based on simple algorithms, enabling the rapid recognition by the user of eight aliphatic acyclic lipid classes, including alkanes, alkenes, aldehydes, ketones, esters, and TMS derivatives of free fatty acids, primary and secondary alcohols, and their homologues with carbon chains varying between 10 and 100 carbons. Additionally, the WaxAlly software provides a section for data organization, internet comparison to NIST and PubChem databases, and academic information about mass fragmentation of acyclic lipids. The software has proven to be a very useful complementary technique in identifying plant wax lipid homologues, and new fragmentation patterns of lipid classes can be added in the future to improve the program.

RESUMO: A osteologia desempenha um papel indispensável para o conhecimento dos padrões de normalidade das diversas espécies, sendo a base para o entendimento zoológico. Mazama nana é bastante conhecido no Brasil, porém descrições morfológicas básicas acerca da espécie são escassas, enquanto Subulo gouazoubira, revalidação atual de Mazama gouazoubira, também é incidente no Brasil e, atualmente, tem sido alvo de diversos estudos filogenéticos. Nesse escopo, no presente estudo, foram preparadas, osteologicamente, 19 cabeças de cervídeos (16 Subulo gouazoubira e três Mazama nana) e, em seguida, tomografias computadorizadas (TCs) foram realizadas a fim de aprimorar as formas de avaliação de acidentes ósseos, além de estruturas internas e forames mediante técnicas de reconstrução em três dimensões (3D) devido a difícil visibilidade em peças intactas. Posteriormente, realizou-se um comparativo entre as reconstruções, fotografias digitais e secções tomográficas transversais do crânio, o qual possibilitou a visualização de peculiaridades e exclusividades anatômicas, como a presença da fenestra nasolacrimomaxilar, detalhamento dos seios paranasais e arquitetura de ossos finos, além do formato exclusivo dos ossos cranianos, em comparação a outras espécies, que apresentam um fenótipo único e genuíno.

ABSTRACT: Osteology plays an indispensable role in understanding the normal patterns of different species, serving as the foundation for zoological understanding. Mazama nana is well-known in Brazil; however, basic morphological descriptions of the species are scarce, while Subulo gouazoubira, currently revalidated as Mazama gouazoubira, is also prevalent in Brazil and has recently been the subject of various phylogenetic studies. In this respect, in the present study, 19 cervid heads (16 Subulo gouazoubira and three Mazama nana) were osteologically prepared. Next, computed tomographies (CTs) were performed to enhance the assessment of bone accidents, as well as internal structures and foramina through three-dimensional (3D) reconstruction techniques due to the difficult visibility in intact specimens. A comparison was then made between the reconstructions, digital photographs, and CT cross-sections of the skull, which enabled the visualization of anatomical peculiarities and exclusivities, such as nasolacrimal-maxillary fenestra, paranasal sinuses, and thin bone architecture, as well as the unique shape of cranial bones, compared to other species that exhibit a unique and genuine phenotype.

ABSTRACT: This research aimed to understand the subject regarding the 2030 Agenda Sustainable Development Goals and food production through literature reviews covering the timespan from 2001 to 2021. Methodologically, this paper is framed as a literature review and uses the Scopus platform to get to the database, selecting 243 papers. The results pointed out that the United States presented the highest number of published documents (126). When it comes to the origin of affiliation, the universities located in the Netherlands (University of Wageningen) and Canada (University of Guelph) present together the highest number of published documents (24). Among the keywords, the most frequent are food safety, followed by the food supply, sustainability, and climate change. Finally, regarding the main subjects tackled during the analyzed time period, it was verified that the issues concerning public policies, land use, and food safety were discussed throughout the entire timespan. In turn, the most recent period, mainly covering the articles published from the year 2021 on, inserts into the discussion agenda the aspects of Covid-19, the pandemic, and its impacts, especially influenced by the setting experienced worldwide. At the same time, other subjects less discussed took the spotlight, also emerging from the Covid-19 pandemic, such as digital agriculture and digital technology, which began to have major relevance. At last, it is possible to infer that reaching sustainable development goals is even more challenging under a pandemic context experienced by all the countries from 2020 to the present day.

Abstract Construction projects are highly complex systems that recurrently present discrepancies between work-as-imagined and work-as-done. Digital technologies, such as photogrammetry using UAVs (drones), are promising support tools to cope with this problem. Therefore, this study aims to evaluate the procedures for developing and assessing the quality of a 3D model generated through photogrammetry from images captured by a drone, comparing it to the as-designed BIM model. Thus, a case study was carried out in a residential low-income housing construction project in Camaçari, Brazil. Compared to the as-designed BIM 3D model, the photogrammetric model presented an average dimensional deviation of -1.68%. The model also presented issues such as occlusions and deformations. The study highlights that both this deviation and the quality of the photogrammetric model can be significantly influenced by the data collection method (e.g., quantity and resolution of photos). The study's primary contribution lies in presenting the potential of UAV usage for image capture in photogrammetry model generation. workasimagined work imagined workasdone. workasdone done. done work-as-done technologies drones, drones , (drones) problem Therefore D drone asdesigned designed Thus lowincome low income Camaçari Brazil 1.68%. 168 1 68 -1.68% deformations e.g., eg e g (e.g. photos. photos . photos) studys s generation (drones 1.68% 16 6 -1.68 e.g. (e.g 1.68 -1.6 e.g 1.6 -1. 1. -1 -

Resumo Projetos de construção são sistemas altamente complexos que apresentam recorrentemente discrepâncias entre o trabalho planejado e o trabalho realizado. Tecnologias digitais, como a fotogrametria com VANTs (drones), são ferramentas de suporte promissoras nesse contexto. Assim, este estudo tem como objetivo avaliar os procedimentos de desenvolvimento e qualidade de um modelo 3D gerado por fotogrametria através de imagens capturadas por drone, comparando-o ao modelo as-designed BIM. Para isso, realizou-se um estudo de caso em uma habitação de interesse social localizada em Camaçari-BA. Comparado ao modelo BIM projetado, o modelo fotogramétrico apresentou um desvio dimensional médio de -1,68%. O modelo também apresentou inconsistências como oclusões e deformações. O estudo mostra que tanto esse desvio como a qualidade do modelo fotogramétrico obtido podem ser consideravelmente influenciados pela forma de coleta dos dados (ex. baixa quantidade e resolução das fotos). A principal contribuição do estudo é apresentar o potencial do uso do VANT para captura de imagens para geração de um modelo de fotogrametria. realizado digitais drones, drones , (drones) contexto Assim D drone comparandoo comparando asdesigned as designed isso realizouse realizou se CamaçariBA.

Resumo No Brasil, construções em madeira do tipo light woodframe possuem envelopamento estrutural do painel dependente do uso de chapas de OSB (Oriented Strand Board), o que implica em uma dificuldade em seu acesso por parte da população. Para ampliar a aplicação do sistema, uma possibilidade consiste em um projeto não atrelado aos monopólios de componentes construtivos. Uma possibilidade é a substituição da camada de envelopamento estrutural dos painéis por tábuas de madeira serrada convencional. Como objetivo esta pesquisa analisa a viabilidade de utilização e o comportamento de painéis de madeira serrada com envelopamento em tábuas de pinus quando solicitados a esforços horizontais, utilizando modelo numérico de simulações em software. O trabalho estuda cinco diferentes tipologias de painéis: um modelo digital de calibração baseado em experimento ensaiado em laboratório; quatro modelos de diferentes configurações, comparando entre si o desempenho estrutural de cada um com dados publicados na literatura. A modelagem digital utilizou dados experimentais já obtidos em trabalhos anteriores. Dos cinco tipos estudados quanto à tensão-deformação, apenas o Modelo 05 não se mostrou viável pela alta concentração de tensão observada nos conectores. Os demais modelos se mostraram adequados aos critérios preconizados por normas e documentos técnicos referenciados.

Abstract In Brazil, light woodframe buildings rely on the use of OSB (Oriented Strand Board), what implies a difficulty in its access by part of the population. To increase the applicability of the system one proposition consists in a woodframe project that is not bound by the monopoly over constructive components. A possible way consists in the substitution of the coating of the panels with standard Pinus boards. The objective of this research is therefore to analyze the viability and the behavior of wood panels with Pinus board coating when submitted to horizontal loads, utilizing as method digital simulations. This paper lists five different panel topologies, to calibrate it: one digital model of a previous lab experiment; four panels with different configurations, comparing them between themselves and with the literature in regards of structural performance. The utilized method was of the digital simulation with previous laboratory data calibration. Among the five types studied, only Model 05 exhibited high stress concentrations at connectors, rendering it unviable. The other models meet the criteria of referenced standards and technical documents.

Abstract This article analyzes how different activisms in Chile feminists, LGTBIQ+, antihegemonic masculinities, and groups opposing sexual and reproductive rights contested the gender order during the country’s constituent process, which unfolded between 2020 and 2023. In particular, we explore the way in which anti-abortion groups mobilized, showing that they not only oppose the interruption of pregnancy, but they also try to re-signify gender as a social construct. From the logic of methodological assemblage, we combined the observation of street demonstrations and digital ethnography through a series of interviews with cyber-activists of “pro-life” organizations. From the analysis conducted on the practices and discourses of these groups, three types of political operations have been identified: a redefinition of the framework of rights at stake when debating abortion; a broadening of the affected subject otherwise restricted to the fetus; and a resignification of feminism. These findings allow us to conclude that such activisms do not represent “anti-gender” positions but rather correspond to a neoconservative gender countermovement.

Resumen En el presente artículo se analiza la forma en que los diferentes activismos en Chile feministas, LGTBIQ+, masculinidades antihegemónicas y grupos que se oponen a los derechos sexuales y reproductivos disputaron el orden de género durante el proceso constituyente del país, desarrollado entre 2020 y 2023. En particular, se explora el modo en que los grupos antiabortistas se movilizaron con el fin de comprender que no solo se oponen a la interrupción del embarazo, sino que tratan de resignificar el género como constructo social. Desde la lógica del ensamblaje metodológico, se combinó la observación de manifestaciones callejeras y la etnografía digital, a través de una serie de entrevistas a ciberactivistas de organizaciones “provida”. A partir del análisis realizado sobre las prácticas y discursos de estos grupos, se han identificado tres tipos de operaciones políticas: una redefinición del marco de los derechos en juego al debatir sobre el aborto; una ampliación del sujeto afectado restringido al feto; y una resignificación del feminismo. Estos hallazgos permiten concluir que tales activismos, más que a posiciones “antigénero”, corresponden a un contramovimiento neoconservador de género.

Abstract: The pandemic period served as a catalyst in the museums' adaptation, leading them to embrace innovation, collaboration, and resilience. As they emerged from the COVID-19 crisis, these institutions found themselves in a unique position to play a vital role in society's rebuilding and in preserving cultural heritage in an ever-changing world. The article aims to explore the main measures adopted, review the scientific literature on the subject, highlight some relevant cases in European, Asian, and American museums, and identify the challenges and dynamics driven in the post-pandemic period. The text stems from a thorough literature review to determine how the museum field should reconfigure its presence, considering three factors: technology, heritage, and audience. A landscape in which the presence of social networks, the rise of online exhibitions, and other digital resources are considered fundamental.

Resumen: El periodo pandémico supuso un catalizador en la adaptación de los museos, llevándolos a abrazar la innovación, la colaboración y la resiliencia. A medida que emergieron de la crisis del covid-19, dichas entidades se encontraron en una posición única para desempeñar un papel vital en la reconstrucción de la sociedad y en la preservación del patrimonio cultural en un mundo en constante cambio. El artículo busca conocer cuáles fueron las principales medidas adoptadas, conocer la literatura científica al respecto, reseñar algunos casos relevantes en museos europeos, asiáticos y americanos, y señalar los retos y las dinámicas impulsadas en el periodo postpandémico. El texto nace de una atenta revisión bibliográfica para delimitar de qué modo el ámbito museístico debe reconfigurar su presencia atendiendo a tres factores: tecnología, patrimonio y público. Un panorama en que la presencia de las redes sociales, el auge de las exposiciones en línea y otros recursos digitales se consideran fundamentales.

Abstract In recent years, digital transformation processes have been gaining relevance. However, not all companies are achieving the same degree of transformation. The presence of barriers and enablers plays a significant role in this process. Furthermore, the extent of digital transformation also impacts how human resources (HR) policies are deployed and influences the effect they have on employees. This work aims to understand how the digital transformation process is occurring from a qualitative approach. Specifically, this study analyzes the main drivers and barriers of firms' digitalization, as well as its effects on companies, people, and human resource practices. Eight semi-structured interviews were conducted with key informants in three companies to gain an in-depth insight into the research problem. ATLAS.ti was used for data analysis and coding. Results show the presence of barriers and facilitators documented in existing literature. However, our results reveal that the business size and the firm's main activity are important variables that affect the extent of digital transformation. The study also reveals the benefits of digitalization in terms of efficiency and human resource autonomy (flexibility, work-life balance). Likewise, the findings unveil the negative consequences of digitalization with risks such as depersonalization and isolation that undermine talent retention.

Resumen En los últimos años, el proceso de transformación digital ha ido ganando importancia. Sin embargo, no todas las empresas adquieren el mismo nivel de transformación. La presencia de barreras y facilitadores desempeña un papel importante en este proceso. Además, el alcance de la transformación digital también influye en cómo se ejecutan las políticas de recursos humanos (RH) y su impacto en los empleados. Este trabajo pretende comprender cómo se está produciendo el proceso de transformación digital desde un enfoque cualitativo. En concreto, en este estudio se analizan los principales impulsores y barreras de la digitalización en las empresas, así como sus efectos sobre la empresa, las personas y, sobre las prácticas de recursos humanos. Se realizaron ocho entrevistas semiestructuradas a informantes clave de tres empresas para conocer en profundidad el problema de investigación. Se utilizó ATLAS.ti para el análisis y la codificación de los datos. Los resultados muestran la existencia de barreras y facilitadores, tal y como ha identificado la literatura existente, sin embargo, nuestros resultados muestran que el tamaño de la empresa y el sector al que pertenece son variables importantes que afectan al nivel de transformación digital. El estudio también revela los beneficios de la digitalización en términos de eficiencia y sobre la autonomía de los recursos humanos (flexibilidad, conciliación). Asimismo, los resultados muestran también los efectos negativos de la digitalización como los riesgos como la despersonalización y el aislamiento que socavan la retención del talento.

ABSTRACT The non-consensual dissemination of sexual content, a type of digital violence that is favored through anonymity, massiveness, and impunity, affects women differentially. Facing this difficult context, Colombia has enormous challenges in supporting women who are at risk or face this sort of violence. The current regulatory development is precarious and there is no criminal offense statement or specific public policies that serve to prevent and to support these cases.

RESUMEN La difusión no consentida de contenido sexual es un tipo de violencia digital que afecta de manera diferencial a las mujeres, favorecido por el anonimato, la masividad y la impunidad. Ante este difícil panorama, Colombia cuenta con enormes retos frente al acompañamiento de las mujeres que están en riesgo o enfrentan estas violencias, teniendo en cuenta que el desarrollo normativo es precario y no existe un tipo penal específico con enfoque de género o políticas públicas específicas que sirvan para prevenir y para acompañar estos casos.

Summary: The fraction of vegetation cover (FVC) and the Leaf Area Index (LAI) are biophysical variables closely related to the evapotranspiration rate of crops and their biomass production. Despite their importance, they are usually not measured directly due to their time-consuming and costly nature; however, they can be estimated on a large scale and near-real-time using spectral information captured in satellite images, although this requires prior validation at the field level. Simple linear regression models were developed and validated using 13 vegetation indices (VI) related to LAI and FCV in alfalfa (Medicago sativa). Three spectral information sources were used: (i) reflectance to derive the VI; (ii) digital photographs processed with the Canopeo application to estimate FVC; and (iii) direct LAI measurements using a ceptometer. Six field samples were taken between March and June, 2020 in four alfalfa plots located in Palmar de Bravo, Puebla, Mexico. To evaluate each VI, the determination coefficient (R2) and the root mean square error (RMSE) were used. We found that the most suitable VI for estimating FVC was the VIgreen (Green Vegetation Index, R2 =0.987 and RMSE = 0.093). For the LAI, the VI that performed best was the NDVI (Normalized Difference Vegetation Index, R2 = 0.935 and RMSE = 0.746). The results showed the suitability and practical utility of spectral information for estimating biophysical variables in alfalfa cultivation and their monitoring.

Resumen: La fracción de cobertura vegetal (FCV) y el índice de área foliar (IAF) son variables biofísicas relacionadas estrechamente con la tasa de evapotranspiración de los cultivos y su producción de biomasa. A pesar de su importancia, usualmente no se miden de manera directa debido al tiempo invertido y costo; sin embargo, se pueden estimar a gran escala y en tiempo casi real mediante información espectral captada en imágenes de satélite, pero esto requiere de su validación a nivel de campo. Se desarrollaron y validaron modelos de regresión lineal simple utilizando 13 índices de vegetación (IV) relacionados con el IAF y la FCV en alfalfa (Medicago sativa). Se usaron tres fuentes de información espectral: (i) La reflectancia para derivar los IV; (ii) fotografías digitales procesadas con Canopeo para estimar la FCV; y (iii) mediciones del IAF utilizando un ceptómetro. Se realizaron seis muestreos de campo entre marzo y junio de 2020, en cuatro parcelas de alfalfa situadas en Palmar de Bravo, Puebla, México. Para evaluar cada IV, se utilizó el coeficiente de determinación (R2) y la raíz del cuadrado medio del error (RCME). Se encontró que el IV más apropiado para estimar la FCV fue el VIgreen (Green Vegetation Index, R2 = 0.987 y RCME = 0.093). En el caso del IAF, el IV que presentó el mejor desempeño fue el Normalized Difference Vegetation Index (NDVI), R2 = 0.935 y RCME = 0.746). Los resultados mostraron la aptitud y utilidad práctica de la información espectral para estimar las variables biofísicas en el cultivo de alfalfa y su monitoreo.
