Authors: Reichert Richard Alecsander , Ramos de Oliveira Micheline , De Micheli Denise , Aparecida da Silva Eroy
Published: April 2024

Para atender às demandas de pessoas com necessidades relacionadas ao uso de substâncias psicoativas inseridas em contextos de vulnerabilidade social, são necessárias análises multinível para identificar aspectos relevantes nos quais devem intervir as políticas e programas de prevenção, redução de danos e tratamento. Em vista disso, este estudo objetivou caracterizar o perfil de usuários de substâncias psicoativas, analisar suas trajetórias sociais e identificar vulnerabilidades associadas ao uso de álcool, crack e outras drogas no centro da cidade de São Paulo (São Paulo, Brasil), na região popularmente conhecida como “Cracolândia”. Tratouse de um estudo de delineamento descritivo-exploratório e de métodos mistos, incluindo dados predominantemente qualitativos, cuja amostra foi composta por 35 participantes. Os dados foram analisados através de metodologia descritiva e análise de conteúdo. A partir dos resultados, verificou-se que essa população está exposta a uma série de vulnerabilidades individuais e processos de vulnerações sociais e político-institucionais, como exclusão nos campos educacional e profissional, afastamento da família e da comunidade, situação de rua, acesso limitado a serviços socioassistenciais, entre outras situações de violência e violações de direitos que podem levar ao uso radical de drogas. No contexto de vida dos usuários, o consumo de drogas mostrou-se associado ao enfrentamento das condições adversas de vida. Espera-se que esses dados possam subsidiar intervenções e políticas públicas sociais e de saúde amplas, integrativas, humanizadas e bioéticas voltadas a esse público.
Cross-modality frame alignment for surgical robot electrode insertion v1
Authors: Liang Lucy , Pirondini Elvira , C Ho Jonathan
Published: April 2024

Scanners for animals often use different image orientations as in clinical scanners. Multi-modal imaging further introduces shifts between images since the animal cannot be placed in the exact same position in the field of view. This necessitates a cross-modality registration step. This protocol details step by step how to use stereotaxic frame features to align (or coregister) monkey head CT and MR images in a clinical ROSA ONE Brain robot (website link), in preparation for electrode insertion planning. Protocol detailing scanning parameters for non-human primates using the 3D printed MR-compatible stereotaxic frame (and critical steps to visualize ear bars for registration) can be found here: dx.doi.org/10.17504/protocols.io.q26g7p7rkgwz/v1 The computer-aided design files and engineering drawings for the frame used in this protocol are publicly available, with the modular design allowing for low cost and manageable manufacturing.

ReViBE: protocol for Refit Visualisation of lithic reduction sequences using the Blender Engine v2
Authors: Sánchez-Martínez Javier , Calmet Katia , Roda Gilabert Xavier
Published: April 2024

Here, we introduce ReViBE, a step-by-step protocol for visualising lithic refits through the utilisation of imaging technologies, photogrammetry, 3D modelling and Blender animation software. Lithic refittings represent high-resolution temporal sequences that shed light in cognitive, organisational and taphonomic aspects of the archaeological record, and have remained integral for the archaeological science since its inception. Despite their popularity, little work has been focused on the representation of refittings, traditionally undertaken through photography and archaeological drawing. While the use of these recording tools are widespread in the discipline, their application in refittings has limitations, as they fail to capture the three-dimensional nature of lithic reduction. Our ReViBE protocol addresses this issue through a step-by-step procedure that combines the creation of 3D models in refittings and their animation, allowing a more dynamic visualization of lithic reduction sequences in high definition. The protocol consists of three main phases in which we explain how to perform photogrammetry on the refitted artifacts, create three-dimensional models from the captured images (e.g., Photoscan/Metashape), and finally, generate animation by reconstructing the motion of each individual piece in a temporal sequence (e.g., Blender). Furthermore, we suggest incorporating protocols employing 3D modelling to aid in the digital visualization of material culture, enhancing the accessibility and study of archaeological heritage.

Heart Rate Variability Parameters for Assessing Autonomic Responses to Brief Rectal Distention in Patients with Irritable Bowel Syndrome v1
Authors: Khawar Ali M , Gong Shiyuan , Chen Jiande
Published: April 2024

Heart rate variability (HRV) has been used to measure autonomic nervous system (ANS) activity noninvasively. The purpose of this study was to identify the most suitable HRV parameters for ANS activity in response to brief rectal distension (RD) in patients with Irritable Bowel Syndrome (IBS). IBS patients participated in a five-session study. During each visit, an ECG was recorded for 15 min for baseline values and during rectal distension. For rectal distension, a balloon was inflated in the rectum and the pressure was increased in steps of 5 mmHg for 30 s; each distension was followed by a 30 s rest period when the balloon was fully deflated (0 mmHg) until either the maximum tolerance of each patient was reached or up to 60 mmHg. The time-domain, frequency-domain and nonlinear HRV parameters were calculated to assess the ANS activity. The values of each HRV parameter were compared between baseline and RD for each of the five visits as well as for all five visits combined. The sensitivity and robustness/reproducibility of each HRV parameter were also assessed. The parameters included the Sympathetic Index (SI); Root Mean Square of Successive Differences (RMSSD); High-Frequency Power (HF); Low-Frequency Power (LF); Normalized HF Power (HFn);Normalized LF Power (LFn); LF/HF; Respiratory Sinus Arrhythmia (RSA); the Poincare Plot’s SD1, SD2 and their ratio;and the pNN50, SDSD, SDNN and SDNN Index. Data from 17 patients were analyzed and compared between baseline and FD and among five sessions. The SI was found to be the most sensitive and robust HRV parameter in detecting the ANS response to RD. Out of nine parasympathetic parameters, only the SDNN and SDNN Index were sensitive enough to detect the parasympathetic modulation to RD during the first visit. The frequency-domain parameters did not show any change in response to RD. It was also observed that the repetitive RD in IBS patients resulted in a decreased autonomic response due to habituation because the amount of change in the HRV parameters was the highest during the first visit but diminished during subsequent visits. In conclusion, the SI and SDNN/SDNN Index are most sensitive at assessing the autonomic response to rectal distention. The autonomic response to rectal distention diminishes in repetitive sessions, demonstrating the necessity of randomization for repetitive tests
Design of Optimal Control Systems in the Frequency Domain by the Functional of the Generalized Work
Authors: Lovchakov V. I.
Published: April 2024

The paper considers the problem of analytical design of optimal controllers (ADOC) for one-dimensional linear stationary objects according to the functional of generalized work (FGW) A. A. Krasovsky. The use of FGW in comparison with the quadratic performance functional greatly simplifies the calculation of the optimal controller — the calculation of its matrix of coefficients mainly consists in solving the linear matrix Lyapunov equation, which, in contrast to the nonlinear matrix Riccati equation, fundamentally reduces the amount of calculations. In addition, the use of FGW provides the best stability margins of the designed system in terms of amplitude and phase. This work is devoted to the development of a method for solving the ADOC problem A. A. Krasovsky in the frequency (complex) domain, which reduces the determination of the transfer function coefficients of the optimal controller for an object of order n to the solution of the corresponding system of n linear algebraic equations. In this regard, the proposed method for solving the ADOC problem by A. A. Krasovsky differs by a much smaller amount of calculations in comparison with the standard method, in which the Lyapunov equation is solved with the desired matrix of dimensions n * n. The proposed method for the synthesis of optimal control systems, which has an analytical nature, became the basis for solving the inverse problem ADOC A. A. Krasovsky, which consists in determining the values of the weight coefficients of the FGW, which provide the given primary quality indicators of the synthesized control system. Using its relations, a relatively simple method for calculating the FGW coefficients based on the given values of the error coefficients for the designed dynamic system has been developed.
Sliding Mode Control Based on Jaya Algorithm of Phase Shift for Two-Rotor Vibration Unit
Authors: Long H. D. , Dudarenko N. A.
Published: April 2024

In this paper, a sliding mode control based on the Jaya algorithm o f phase shift for a two-rotor vibration unit is presented. A two-rotor vibration unit is a highly nonlinear system that has many applications in practical systems. The control problem for this model is to design controllers to ensure phase shift according to the desired value and synchronize the speed of the two rotors. To solve this problem, the authors use the PI controllers for synchronizing the speed of the two rotors and the sliding mode controller for the phase shift. PI control is an effective method to design controllers for practical systems. Besides, Sliding Mode Control (SMC) is one of the most effective methods for designing robust controllers for nonlinear systems affected by external disturbances. However, defining the coefficients of PI controllers and sliding mode controllers is the challenge for researchers. In this study, the Jaya algorithm is used to find the coefficients of these controllers that guarantee the desired phase shift of two rotors, the synchronizing speed of two rotors, and the limitation of control laws. The simulation results are illustrated to show the effectiveness of the proposed method.
Paradoxes of Kindness in the Context of Prosocial Behavior: Analysis of Modern Concepts
Authors: Ryaguzova E.V.
Published: April 2024

Objective. Analysis of the modern concepts of kindness as a moral and ethical construct and a predictor of prosocial human behavior, to identify paradoxes of kindness, indicating the multidimensionality and multidirectionality of the content of kindness, the ambivalence of the consequences of manifestation and the ambiguity of interpretation by the subjects of interaction.
Background. In the modern information technology world, the problem of preserving the human in man and his moral cultural code is clearly identified, which is clearly intensifying in an era of uncertainty, instability and global risks. Kindness as a virtue and value, a personal quality and one of the predictors of prosocial behavior, having an interdisciplinary status, is studied in sufficient detail by various researchers, but not all of their results are presented in the domestic literature, and therefore their consolidation and clarification of the “kindness” construct in within the framework of social psychology.
Conclusions. Main conclusions. The concept of “kindness” is clarified as an ethical construct of the individual and a predictor of prosocial behavior, as well as a social norm that regulates interpersonal interactions, strengthens trust and ensures social connections. “Paradoxes” of kindness have been identified, containing multidirectional psychological orientations – care for the Other and care for oneself, ambivalent consequences of showing kindness and its ambiguous interpretation by the subjects of interaction. The prospects for empirical research aimed at studying subjective ideas about kindness, diagnosing its modes, and identifying socio-psychological mediators and moderators are identified.

Published: April 2024

A 20-year-old female patient presented with localized erythematous scaly lichenified plaques on her right lower leg. Despite traditional treatments, the lesions consistently recurred in previously affected anatomical locations. Bacterial culture was performed, and Staphylococcus simulans was identified on both lesional and nonlesional skin.
Histopathological examination revealed parakeratosis, Munro microabscess, hypogranulosis and regular acanthosis with an elongated rete. Based on clinical and histological findings, the patient was finally diagnosed with possible psoriasis. Although S. simulans is a common livestock colonizer, it rarely colonizes human skin. Herein, we report
the first case of S. simulans colonization in a recurrent psoriatic lesion in previously affected anatomical locations.
6D Hyperchaotic Encryption Model for Ensuring Security to 3D Printed Models and Medical Images
Authors: John Siju , Kumar S. N.
Published: April 2024

In the 6G era, where ultra-fast and reliable communication is expected to be ubiquitous, encryption shall continue to play a crucial role in ensuring the security and privacy of data. Encryption and decryption of medical images and 3D printed models using 6D hyperchaotic function is proposed in this research work for ensuring security in data transfer. Here we envisage using a six-dimensional hyperchaotic system for encryption purposes which shall offer a high level of security due to its complex and unpredictable dynamics with multiple positive Lyapunov exponents. This system can potentially enhance the encryption process for 3D objects and medical images, ensuring the protection of sensitive data and preventing unauthorized access. A hyperchaotic system is a type of dynamical system characterized by exhibiting more than one positive Lyapunov exponent, which indicates strong sensitivity to initial conditions. These systems have more degrees of freedom and complex and intricate dynamics compared to standard chaotic systems. The security of the encryption scheme depends on the complexity of the hyperchaotic system and the randomness of the secret key. The parameters of a 6D hyperchaotic system shall be used as an encryption key with six dimensions, each with its range of values, and shall provide many possible keys. In this work, we implemented a 6D hyperchaotic system for the encryption of the 3D printed model and medical images. The performance evaluation was done by metrics entropy, correlation, Number of Pixels Change Rate (NPCR), and Unified Averaged Changed Intensity (UACI) which revealed the robustness of the encryption model in ensuring security. Hyperchaotic systems can be efficiently implemented in parallel computing architectures, which allow faster encryption and decryption processes.
TRAJETÓRIAS DE DIRETORAS ESCOLARES EM UBERLÂNDIA: ATRAVESSAMENTOS DE GÊNERO, CLASSE E POLÍTICA ELEITORAL
Authors: Muniz Coutinho Priscila , Vannuchi Maria Lúcia
Published: April 2024

A partir de entrevistas semiestruturadas com oito diretoras de escolas da rede municipal de Ensino Fundamental I desenvolvemos uma discussão sobre a influência de questões de gênero e da política partidária local na gestão escolar da cidade de Uberlândia (MG). As entrevistas correspondem ao produto de uma pesquisa de campo que subsidiou uma dissertação de mestrado defendida em 2018, no Programa de Pós-graduação em Ciências Sociais da Universidade Federal de Uberlândia, sobre o perfil profissional das diretoras. A metodologia utilizada para o tratamento das informações das entrevistas e questionários socioeconômicos foi a Análise de Conteúdo, de Laurence Bardin. Como referencial teórico para discutir questões de trabalho e gênero utilizamos as Relações Sociais de Sexo decorrentes da Divisão Sexual do Trabalho, ancoradas nos estudos de Helena Hirata e Danièle Kergoat. Também verificamos uma tensão relacionada à continuidade no cargo de gestão por parte das entrevistadas diretamente condicionada aos resultados de iminente pleito eleitoral no município. Nesse aspecto, retomamos a pesquisa para discorrer sobre as implicações políticas na gestão escolar em observação à legislação atual e o ranço histórico da ingerência da política partidária ainda não superado na educação brasileira. Ampliamos o escopo da análise sobre a configuração da gestão escolar em nível local no IV Seminário do Grupo de Pesquisa Educação de Mulheres nos séculos XIX e XX e II Encontro do Grupo de Pesquisa Arquivos Pessoais, Patrimônio e Educação, promovidos pela Universidade Estadual do Rio de Janeiro em março de 2023, sendo possível verificar a publicação do resumo nos Anais do evento. Neste texto trazemos o fechamento dessa trajetória de estudos sobre a gestão escolar na rede municipal de ensino da cidade de Uberlândia (MG).
CUIDADOS, ATIVISMO E GÊNERO: UM ESTUDO DE CASO E ALGUMAS DISCUSSÕES
Authors: Franco Leal Giuliana , Da Silva Batista Vitório Amanda
Published: April 2024

Existe uma relação entre cuidados privados socialmente atribuídos às mulheres e ativismo ambiental? Essa pergunta é respondida inicialmente em relação ao estudo de caso de um coletivo de mulheres que se organizaram inicialmente como mães em busca de alimentação saudável e sustentável para seus filhos pequenos. Com base nesse caso, desenha-se a hipótese de que os cuidados com a família, atribuídos às mulheres, tem o potencial de despertá-las para o ativismo ambiental, em condições favoráveis; porém, esse mesmo cuidado coloca-se como uma barreira a mais para a permanência na participação na vida pública. Essas ideias são em seguida discutidas à luz de vertentes do pensamento ecofeminista, que relaciona o papel das mulheres de responsáveis pelo trabalho de reprodução da vida com seu interesse por um olhar de cuidado sobre o ambiente.
MATERNAGEM E RUPTURA: SENTIDOS EMANCIPATÓRIOS DE MATERNIDADE A PARTIR DE EXPERIÊNCIAS DE AMAMENTAÇÃO NO BRASIL CONTEMPORÂNEO
Authors: Braga Raquel
Published: April 2024

Relacionando alguns significados em torno da construção social e histórica da “mulher”, bem como da “maternidade” enquanto instituição (Rich, 1986), agrego perspectivas antropológicas de diversos contextos de maternidade para o debate em torno das práticas de maternagem no Brasil contemporâneo. Após traçar um quadro teórico e etnográfico apontando para moralidades em torno da conceitualização de tais categorias, articulo dados de pesquisa etnográfica realizada entre 2019-2022 analisando, online, discursos e imagens de perfis no Instagram de 11 mulheres ativistas pela amamentação – à semelhança do movimento social lactivismo na Espanha, conforme Massó Guijarro (2015). Argumento que tais mulheres experienciam, a partir da maternidade e, especificamente, da amamentação, o que considero uma ruptura (Miller, 2005) potencialmente transformadora de suas trajetórias, percepções políticas e entendimentos de si. Tais ativistas, através de seus discursos e relações online, atribuem sentidos potencialmente emancipatórios comuns a experiências individuais, questionando prescrições e moralidades impostas às mulheres de forma ampla e arraigada, bem como evidenciando contradições e ambiguidades na maternidade e na maternagem.

MATERNIDADES, RELAÇÕES DE GÊNERO E DESIGUALDADES HISTÓRICAS: CONDIÇÕES SOCIAIS, HERANÇAS CULTURAIS E MATERNIDADES NORMATIVAS EM TEMPOS DE COVID-19 NO BRASIL
Authors: Eiras Coelho Soares Ana Carolina , Magalhães Sônia Maria de
Published: April 2024

Este artigo pretende apresentar os resultados parciais de uma ampla investigação sobre os impactos da COVID-19 na vida da comunidade universitária da Universidade Federal de Goiás, localizada no Centro-Oeste do Brasil, sejam eles docentes, técnicos administrativos e discentes para embasar ações que possam discutir academicamente e promover debates sobre equidade de gênero. O isolamento social no ambiente doméstico tem evidenciado problemas comuns na esfera doméstica, onde as mulheres, especialmente as mães, enfrentam a maior carga de trabalho não remunerado de cuidado e gestão da casa. Para além de serem as principais responsáveis pelas tarefas domésticas e pelos cuidados às pessoas em casa em geral, há também a carga mental do trabalho emocional, uma vez que as mulheres são, na maioria das vezes, responsáveis pelo planeamento e gestão da casa, de todas as refeições e da vida quotidiana. A ideia da "boa mãe" também se apresenta como um problema neste cenário. Acrescentamos ainda, na atual conjuntura, a alarmante constatação de que a pandemia vem reduzindo a produção de trabalhos acadêmicos assinados por mulheres cientistas, pois a parte do dia dedicada ao trabalho intelectual só se torna possível após a interminável jornada de trabalho familiar e doméstico. A cobrança pela produção científica, no entanto, continua a mesma o que aumenta ainda mais o abismo das desigualdades de gênero entre a produção acadêmica.
Role of application of SWCR guidelines in management of left trochanter pressure injury (PI)
Authors: Chittoria Ravi Kumar , Kannan Aishvarya , Chakiath Jacob Antony
Published: April 2024

A pressure injury is localized tissue necrosis following pressure injury to the skin and/or underlying tissue for prolonged period. The process of ulceration is aggravated by simultaneous shear or direct injury to skin continuity. The terms “decubitus ulcer,” “bedsore,” and “pressure sore” are often used interchangeably, but they do not describe the condition as accurately as pressure injury. The word ‘decubitus’ – derived from the Latin ‘decumbo’ or ‘decumbere’, meaning ‘to lie down’ or ‘recline’ – as the ulcer occur commonly over areas of bony prominences in recumbent position, e.g., the sacrum, trochanter, heel, and occiput. The term ‘pressure ulcer’ describes these ulcers better with pressure as an important etiologic factor. Aim of this case report is to assess the role of applying SWCR guidelines in management of pressure injuries.

Published: April 2024

Burns are one of the most common injuries among the children, which could due to thermal, scald, electrical burn injuries. Scald injuries tend to be the most common type of burn injury under the age of five, accounting for over 65% of the cases. In current scenario, various scaffolds are used to improve the quality of healing process and reduce the scar formation. Collagen acts as a scaffold through which regeneration of tissues occurs and also helps in new vessel formation. Other scaffolds like amniotic membrane helps in proper epithelization and reduces scarring. It also has unique anti inflammatory, bacteriostatic property. In this study we used amniotic membrane heterograft as a biological dressing in a paediatric patient with burn wounds to face.

Authors: Poraj-Weder Magdalena , Szulawski Michał , Rogoza Radosław , Jasielska Dorota , Pios Anna
Published: April 2024

The aim of this study (N = 713) was to adapt the Appearance Schemas Inventory–Revised into Polish and evaluate its psychometric properties. The ASI-R is a widely used tool for measuring appearance schemas, but it is currently not available in Polish. The adaptation of the ASI-R has the potential to fill this gap and encourage research in the Polish community. The validation of the scale was conducted on two separate samples of healthy adults. Although the results indicate that the Polish version of the scale, in contrast to the original one, exhibits a one-factor structure, its psychometric properties are robust. The scale demonstrates high internal consistency and sound construct validity, established through correlations with various aspects of psychosocial functioning, along with body image and sociocultural attitudes toward appearance. The scale seems to be gender-invariant and can be utilized in future studies that adopt a cognitive-behavioral approach to appearance schemas.
Conflict and Facilitation Between Work and Family Roles and Goal Realization in Entrepreneurs
Authors: Łagowska Kinga , Łaguna Mariola , Purc Ewelina
Published: April 2024

Entrepreneurs running their businesses usually pursue goals associated with work and family functioning. The efficiency of goal realization in these two areas of activity varies and may depend on balance between the two domains. The study aimed to answer the question of how interplays between the work and family domains (work-to-family conflict, family-to-work conflict, work-to-family facilitation, and family-to-work facilitation) were related to the realization of work and family goals in entrepreneurs. It also tested if sex was a moderator of these relationships. A total of 246 entrepreneurs participated in the study; they were married or in stable non-marital relationships. Structural equation modeling showed that family-to-work conflict is negatively related to work goal realization and family goal realization, and work-to-family facilitation is positively related to family goal realization. Sex does not moderate the relationships analyzed. The study provides insight into the relationships of conflict and facilitation to goal realization in people running their businesses.

Authors: Molińska Weronika , Rajchert Joanna , Bodecka-Zych Marta
Published: April 2024

The following study focuses on individual differences between musicians who play solo (performing individually or as leaders), and musicians performing as part of a chamber ensemble, band, choir, orchestra, etc. We predicted that soloists would be higher on grandiose narcissism and self-efficacy. The results showed that soloists (n = 59) not only were higher on narcissism, but also had higher self-efficacy scores than musicians who perform in ensembles (n = 65). However, soloist and band players are not different in narcissism and self-efficacy when the other trait is controlled, which indicates that common features of both traits differentiate solo and band musicians. Results raise further questions on what factors affect the development of a musician’s career path.

La araña roja, Tetranychus urticae Koch, es la principal plaga del cultivo de rosas para corte (Rosa hybrida). Observaciones preliminares indican que plantas con alta densidad de araña roja presentan deficiencias nutrimentales, pero no existe información cuantitativa al respecto. El objetivo fue determinar la relación que existe entre la densidad de araña roja y el estado nutrimental de rosal 'Polo'. En cuatro muestreos, se seleccionaron 60 plantas libres de araña roja y 60 plantas con más de 60 ácaros por hoja (infestación alta). En ambos casos se determinó, mediante análisis químico foliar, la cantidad de macro y micronutrimentos, así como el índice de desbalance nutricional (IDN). Las plantas con presencia de araña roja muestran desequilibrio nutrimental debido a la reducción en la concentración foliar de nitrógeno, fósforo, potasio, calcio, manganeso y cobre. El porcentaje de reducción de la concentración de dichos elementos osciló entre 0.3 y 29 % respecto al testigo.

Se realizó una modificación física (autoclaveado) y cinco modificaciones químicas (lintnerización, entrecruzamiento, acetilación, hidroxipropilación y oxidación) al almidón nativo de avena. Los almidones se mezclaron con quitosano (Q) y plastificante (glicerol) para elaborar películas. Las soluciones formadoras de película (SFP) se caracterizaron reológicamente. En las películas se evaluaron las propiedades físicas (color, grosor, humedad y solubilidad), la permeabilidad al vapor de agua y al oxígeno (10 y 25 °C) y las propiedades mecánicas. La actividad antibacterial se evaluó durante 21 días contra Eschericia coli, Staphylococcus aureus y Listeria monocytogenes por difusión en agar mediante el conteo de coliformes aerobios totales y fecales. Todas las SFP presentaron comportamiento pseudoplástico.

El estudio de respiración del suelo (emisión microbiana de CO2) por incorporación de residuos orgánicos (RO) provenientes de la agroindustria (bagazo y composta de bagazo), permite estimar el efecto ambiental en relación a la emisión de CO2 por la mineralización del carbono durante su proceso de descomposición, lo cual debe ser considerado desde el punto de vista de cambio climático. Por lo anterior, el objetivo fue evaluar la dinámica de emisión de CO2 por la mineralización de cuatro materiales lignocelulósicos, incorporados en suelos de diferente textura. Mediante la técnica de respiración alcalina, se cuantificó la respiración de CO2 en Regosol y Luvisol por incorporación de dos bagazos (TBD y TBA) y sus compostas (TCD y TCA) durante 30 días bajo condiciones controladas de humedad y temperatura. Los tratamientos TBD y TBA, incrementaron la actividad microbiológica con mayores emisiones; mientras que los tratamientos TCD y TCA, incrementaron el contenido de C orgánico suelo (COS) con menores emisiones. La emisión de CO2 se relacionó con la mineralización de los RO y ésta a su vez con su composición química y su resistencia a la descomposición, además la dinámica de las emisiones fue diferente por tipo de material y por tipo de suelo. La incorporación de RO de tipo bagazos, es una opción para incrementar la actividad microbiana edáfica, pero con mayor emisiones de gases de efecto invernadero (GEI); mientras que los RO de compostas generan un incremento en la captura de COS y, por ende, mayor almacén de C y una menor emisión de CO2.

The Elba Curves

Published: April 2024

This article deals with special curves similar to those known in mathematics as Lamé curves. Their equations have a certain similarity with the equations of Lamé curves. But these curves are more like ellipses in appearance. Like ellipses, they have major and minor axes. These are such curves that their major and minor semi-axis coincide with an ellipse but are different than an ellipse. The main feature of these curves is that for any triangle whose base coincides with the axis of a given curve and the vertex is on a given curve, the condition an+bn=cn is obtained. The number “n” is called the degree or rank of this curve. To distinguish this group of curves, we called them Elbe curves. The equations of these lines are also provided in the paper.
Bi-directional Full-Color Generation and Tri-channel Information Encoding Based on a Plasmonic Metasurface
Authors: Huo Dewang , Li Guoqiang
Published: April 2024

Dynamic optical structural color is always desired in various display applications and usually involves active materials. Full-color generation, especially bi-directional full-color generation in both reflective and transmissive modes, without any active materials included has been rarely investigated. Herein, we demonstrate a scheme of bi-directional full-color generation based on a plasmonic metasurface modulated by rotation of the polarization angle of the incident light without varying the geometry and the optical properties of the materials and the environment where the metasurface resides. The metasurface unit cell consists of plasmonic modules aligning in three directions and is patterned in a square array. The metasurface structural color device generates full colors in both reflection and transmission. Based on the proposed polarization-dependent structural color, information encoding of three multiplexed animal images and quick-responsive (QR) codes is demonstrated to verify the efficient information encoding and decoding of the proposed scheme. The animals can be seen under different polarization incidence and the QR codes can be successfully decoded by the polarization rotation in transmission. The proposed bi-directional full-color generation metasurface has great potential in applications such as kaleidoscope generation, anti-counterfeiting, dynamic color display, and optical information encoding.

The maintenance of traditional agricultural practices in protected small islands is closely linked to the preservation of the land, the protection of natural resources, and the conservation of local traditions. For this purpose, the Tuscan Archipelago National Park promoted the census of ancient horticultural varieties preserved by some farmers on the island of Elba. The survey revealed a deep-rooted historical, cultural, social, and economic link between this germplasm and the island’s territory. A scientific characterization of the landrace under ethnobotanical, morphological, and genetic aspects was carried out. Among these local varieties, two landraces of the Brassica species and three landraces of the Phaseolus species were identified and analyzed in this study. To ascertain their distinguishability and uniqueness, similar varieties were also identified based on morpho-physiological characteristics or territorial proximity and compared with the Elban landraces. Morpho-phenological data were collected, and molecular analyses were carried out using Simple Sequence Repeats (SSR) markers. Ten different SSR loci were considered for the Phaseolus species and nine for the Brassica species. The Tuscan Archipelago landraces showed a high level of internal variability but were clearly distinct from each other and from the analyzed varieties, as shown by AMOVA (Analysis of Molecular Variance). Their distinctness was further highlighted by the UPGMA dendrogram obtained from the genetic distance matrix. The same results were confirmed by Principal Coordinate Analysis (PCoA). This study confirms the peculiarity of the Elban landraces, their biodiversity is a heritage to be safeguarded, which can also be used in future breeding programs. These ancient Elban landraces were allocated to local farmers (most were young farmers) to protect them from extinction and to promote more resilient varieties cultivation compared to commercial hybrids widely spread in the area. Local farmhouses also play a strategic role in safeguarding the germplasm and dissemination of sustainable agricultural practices. There is high demand for ancient Elban landraces, this has led to the development of a new local economy balanced between agricultural tradition and innovation.
