Authors: Xu Yanting , Wu Zhenzeng , Li Ao , Chen Nairong , Rao Jiuping , Zeng Qinzhi
Published: February 2024

Owing to the environmental pollution caused by petroleum-based packaging materials, there is an imminent need to develop novel food packaging materials. Nanocellulose, which is a one-dimensional structure, has excellent physical and chemical properties, such as renewability, degradability, sound mechanical properties, and good biocompatibility, indicating promising applications in modern industry, particularly in food packaging. This article introduces nanocellulose, followed by its extraction methods and the preparation of relevant composite films. Meanwhile, the performances of nanocellulose composite films in improving the mechanical, barrier (oxygen, water vapor, ultraviolet) and thermal properties of food packaging materials and the development of biodegradable or edible packaging materials in the food industry are elaborated. In addition, the excellent performances of nanocellulose composites for the packaging and preservation of various food categories are outlined. This study provides a theoretical framework for the development and utilization of nanocellulose composite films in the food packaging industry.

Authors: Dong Guanghe , Luo Zhumei , Guo Tao , Zhang Xiaoxu , Shan Rong , Dai Linsheng
Published: February 2024

This study focuses on the splitter blade pump–turbine as the research object to analyze the problems of hump characteristics and the hysteresis effect. We simulated the operation of the pump condition with small opening of the guide vane, analyzed the hydraulic loss by using the entropy production theory and entropy wall function, and investigated the study of internal flow transfer characteristics. In this paper, it was first verified that the maximum error of the energy loss calculated by the pressure method and the entropy production method was less than 6% for the working zone. From the quantified energy loss results, a significant instability feature was observed in the 0.65 QBEP–0.9 QBEP operating interval, accompanied by the phenomenon of the non-overlapping of the characteristic curves. The results show that the hump characteristic with hysteresis effect also exists in the splitter blade pump–turbine. The percentage of energy loss in the hump zone is in descending order of runner, guide vanes, spiral casing, and draft tube, but this changes again at low flow rates. By analyzing the high-entropy production region, it was found that the high-hydraulic-loss region is mainly distributed at the trailing edge of the long blade in the vane-less space, which is different from the traditional runner.

Authors: Losidis Sotirios , Dermitzakis Vaios
Published: February 2024

We obtain the upper and lower bounds for the ruin probability in the Sparre–Andersen model. These bounds are established under various conditions: when the adjustment coefficient exists, when it does not exist, and when the interarrival distribution belongs to certain aging classes. Additionally, we improve the Lundberg upper bound for the ruin probability.
Instantaneous Extraction of Indoor Environment from Radar Sensor-Based Mapping
Authors: Cho Seonmin , Kwak Seungheon , Lee Seongwook
Published: February 2024

In this paper, we propose a method for extracting the structure of an indoor environment using radar. When using the radar in an indoor environment, ghost targets are observed through the multipath propagation of radio waves. The presence of these ghost targets obstructs accurate mapping in the indoor environment, consequently hindering the extraction of the indoor environment. Therefore, we propose a deep learning-based method that uses image-to-image translation to extract the structure of the indoor environment by removing ghost targets from the indoor environment map. In this paper, the proposed method employs a conditional generative adversarial network (CGAN), which includes a U-Net-based generator and a patch-generative adversarial network-based discriminator. By repeating the process of determining whether the structure of the generated indoor environment is real or fake, CGAN ultimately returns a structure similar to the real environment. First, we generate a map of the indoor environment using radar, which includes ghost targets. Next, the structure of the indoor environment is extracted from the map using the proposed method. Then, we compare the proposed method, which is based on the structural similarity index and structural content, with the k-nearest neighbors algorithm, Hough transform, and density-based spatial clustering of applications with noise-based environment extraction method. When comparing the methods, our proposed method offers the advantage of extracting a more accurate environment without requiring parameter adjustments, even when the environment is changed.

Published: February 2024

Spatial cognition plays a crucial role in academic achievement, particularly in science, technology, engineering, and mathematics (STEM) domains. Immersive virtual environments (VRs) have the growing potential to reduce cognitive load and improve spatial reasoning. However, traditional methods struggle to assess the mental effort required for visuospatial processes due to the difficulty in verbalizing actions and other limitations in self-reported evaluations. In this neuroergonomics study, we aimed to capture the neural activity associated with cognitive workload during visuospatial tasks and evaluate the impact of the visualization medium on visuospatial task performance. We utilized functional near-infrared spectroscopy (fNIRS) wearable neuroimaging to assess cognitive effort during spatial-reasoning-based problem-solving and compared a VR, a computer screen, and a physical real-world task presentation. Our results reveal a higher neural efficiency in the prefrontal cortex (PFC) during 3D geometry puzzles in VR settings compared to the settings in the physical world and on the computer screen. VR appears to reduce the visuospatial task load by facilitating spatial visualization and providing visual cues. This makes it a valuable tool for spatial cognition training, especially for beginners. Additionally, our multimodal approach allows for progressively increasing task complexity, maintaining a challenge throughout training. This study underscores the potential of VR in developing spatial skills and highlights the value of comparing brain data and human interaction across different training settings.

Published: February 2024

Metal oxide semiconductor hetero- and homojunctions are commonly constructed to improve the performance of hydrogen sensors at room temperature. In this study, a simple two-step hydrothermal method was employed to prepare TiO2 films with homojunctions of rutile and anatase phases (denoted as TiO2-R/A). Then, the microstructure of anatase-phase TiO2 was altered by controlling the amount of hydrochloric acid to realize a more favorable porous structure for charge transport and a larger surface area for contact with H2. The sensor used a Pt interdigital electrode. At an optimal HCl dosage (25 mL), anatase-phase TiO2 uniformly covered rutile-phase TiO2 nanorods, resulting in a greater response to H2 at 2500 ppm compared with that of a rutile TiO2 nanorod sensor by a factor of 1153. The response time was 21 s, mainly because the homojunction formed by the TiO2 rutile and anatase phases increased the synergistic effect of the charge transfer and potential barrier between the two phases, resulting in the formation of more superoxide (O2−) free radicals on the surface. Furthermore, the porous structure increased the surface area for H2 adsorption. The TiO2-R/A-based sensor exhibited high selectivity, long-term stability, and a fast response. This study provides new insights into the design of commercially competitive hydrogen sensors.
IHIBE: A Hierarchical and Delegated Access Control Mechanism for IoT Environments
Authors: Purnama Hari , Mambo Masahiro
Published: February 2024

Ensuring authorized access control in the IoT is vital for privacy and safety protection. Our study presents the novel IHIBE framework, which combines IOTA (a distributed ledger technology) with hierarchical identity-based encryption (HIBE), thereby enhancing both IoT security and scalability. This approach secures access tokens and policies while reducing the computational demand on data owners. Our empirical findings reveal a significant performance gap, with access rights delegation on the Raspberry Pi 4 exceeding those on AWS by over 250%. Moreover, our analysis uncovers optimal identity policy depths: up to 640 identities on AWS and 640 on the Raspberry Pi 4 for systems with higher tolerable delays, and 320 identities on AWS versus 160 on the Raspberry Pi 4 for systems with lower tolerable delays. The system shows practical viability, exhibiting insignificant operational time differences compared to Zhang et al.’s schemes, particularly in access rights verification processes, with a minimal difference of 33.35%. Our extensive security assessment, encompassing scenarios like encrypted token theft and compromise of authority, affirms the efficacy of our challenge-response and last-word challenge (LWC) mechanisms. This study underscores the importance of platform choice in IoT system architectures and provides insights for deploying efficient, secure, and scalable IoT environments.

This paper introduces an approach to the automated measurement and analysis of dairy cows using 3D point cloud technology. The integration of advanced sensing techniques enables the collection of non-intrusive, precise data, facilitating comprehensive monitoring of key parameters related to the health, well-being, and productivity of dairy cows. The proposed system employs 3D imaging sensors to capture detailed information about various parts of dairy cows, generating accurate, high-resolution point clouds. A robust automated algorithm has been developed to process these point clouds and extract relevant metrics such as dairy cow stature height, rump width, rump angle, and front teat length. Based on the measured data combined with expert assessments of dairy cows, the quality indices of dairy cows are automatically evaluated and extracted. By leveraging this technology, dairy farmers can gain real-time insights into the health status of individual cows and the overall herd. Additionally, the automated analysis facilitates efficient management practices and optimizes feeding strategies and resource allocation. The results of field trials and validation studies demonstrate the effectiveness and reliability of the automated 3D point cloud approach in dairy farm environments. The errors between manually measured values of dairy cow height, rump angle, and front teat length, and those calculated by the auto-measurement algorithm were within 0.7 cm, with no observed exceedance of errors in comparison to manual measurements. This research contributes to the burgeoning field of precision livestock farming, offering a technological solution that not only enhances productivity but also aligns with contemporary standards for sustainable and ethical animal husbandry practices.

Regenerative Development Model: A Life Cycle-Based Methodology for the Definition of Regenerative Contribution Units (RCUs)
Authors: Del Borghi Adriana , Gallo Michela , Gagliano Erica , Eleuteri Vienna
Published: February 2024

In the “contributive” approach, balancing greenhouse gas (GHG) emissions cannot be considered comprehensive, as all footprints, such as ecological and water, shall be assessed and balanced by regenerative actions contributing not only to carbon removal, but also to the regeneration of biodiversity, land, and water. A survey on existing methodologies for the assessment of the damage (environmental burden) and the calculation of the environmental repair (offsets) has been presented in this work. Its outcome pointed out a lack of scientific knowledge on how to put metrics beyond the regenerative development model and in particular on how life cycle assessment (LCA) can scientifically support a number of key features essential to develop a new methodology. The proposed approach is based on three pillars: reduce, remove, and repair. Indeed, this paper aims to develop a methodological LCA-based approach for the definition of Regenerative Contribution Units (RCUs) to quantitatively assess the contribution of projects in line with Sustainable Developments Goals (SDGs) and the framework of regenerative model development. These regenerative units might be marketed locally and globally by enterprises interested in purchasing such assets to scientifically and ethically comply with their corporate ESG obligations. Furthermore, the novelty and feasibility of the proposed approach has been preliminarily investigated through an example of footprints balancing.
Water Conservation Implications Based on Tempo-Spatial Characteristics of Water Footprint in the Water-Receiving Areas of the South-to-North Water Diversion Project, China
Authors: Feng Ziheng , Sun Liying
Published: February 2024

In order to continuously promote water conservation efforts to alleviate the pressure of water diversion, water footprint (WF) is used as an effective tool to measure water utilization in the water-receiving areas of the Middle Route and Eastern Route of the South-to-North Water Diversion Project (SNWDP). The tempo-spatial variations of WF and spatial equilibrium of water footprint intensity (WFI) in the study area are quantified using the Mann–Kandle trend test, Sen’s slope, and Dagum Gini coefficient decomposition method for the years of 2005–2020. The results show that WF has a significant decreasing trend (Sen’s slop < 0, significant level < 0.05) in 17 cities in the study area, whereas WF shows a significant increasing trend (Sen’s slop > 0, significant level < 0.05) in 10 cities. Cities in the water-receiving areas are categorized into three types based on the contribution of the water utilization sector to changes in WF as follows: agriculture water-dominated city (AD), domestic and ecological water-dominated city (DED), and virtual water trade-dominated city (VWTD). Accordingly, targeted water conservation recommendations are made for these three kinds of cities, and it is suggested that AD, DED, and VWTD cities need to focus on advanced irrigation technologies, water reuse, and trade restructuring, respectively. The overall Gini coefficient of WFI fluctuates between 0.219 and 0.267 in the water-receiving areas of the Middle Route, which is dominated by the differences in city level. However, it fluctuates between 0.412 and 0.278 in the water-receiving areas of the Eastern Route, which is dominated by the differences in provincial level. Accordingly, water conservation hotspots are determined at the city level in the Middle Route and at the provincial level in the Eastern Route with different water management policies. These results provide a scientific support for water conservation management in the water-receiving areas of the SNWDP, as well as a methodological reference for the tempo-spatial characteristics of WF and their implications for water conservation.
Redesigning Meso-Institutions in the Social Economy to Deal with Uncertainty: The Case of CGM Network
Authors: Battistoni Francesca , Quaggiotto Giulio , Zandonai Flaviano
Published: February 2024

How can institutions in the social economy adapt to become more effective in dealing with the uncertainty of system transformation? This article focuses on “meso-institutions”, which we define as those that originated neither from a bottom-up (grassroots) approach nor from a top-down mandate (bureaucracy). In particular, it examines the case of CGM, a network of 600 social enterprises in Italy, to investigate how it is renewing its institutional configuration and mandate to better respond to both external and internal changes. CGM has the ambition to be a “reconfigurator” of multi-local systems that can establish new rules of the game in front of the main societal challenges. This entails adopting an innovative approach to define its strategy (from a classic “five-year plan” to a “compass”), reconfiguring its role (from a solution provider to a backbone organisation) and encouraging its members to embrace digitalisation, open innovation and a new business model (platform-based). The article will focus on the tensions and opportunities that this process is surfacing while pointing to broader lessons for institutional innovation.
Natural Polymorphisms D60E and I62V Stabilize a Closed Conformation in HIV-1 Protease in the Absence of an Inhibitor or Substrate
Authors: Tran Trang T. , Fanucci Gail E.
Published: February 2024

HIV infection remains a global health issue plagued by drug resistance and virological failure. Natural polymorphisms (NPs) contained within several African and Brazilian protease (PR) variants have been shown to induce a conformational landscape of more closed conformations compared to the sequence of subtype B prevalent in North America and Western Europe. Here we demonstrate through experimental pulsed EPR distance measurements and molecular dynamic (MD) simulations that the two common NPs D60E and I62V found within subtypes F and H can induce a closed conformation when introduced into HIV-1PR subtype B. Specifically, D60E alters the conformation in subtype B through the formation of a salt bridge with residue K43 contained within the nexus between the flap and hinge region of the HIV-1 PR fold. On the other hand, I62V modulates the packing of the hydrophobic cluster of the cantilever and fulcrum, also resulting in a more closed conformation.
Mycoplasma agalactiae Vaccines: Current Status, Hurdles, and Opportunities Due to Advances in Pathogenicity Studies
Authors: Barbosa Maysa Santos , Sampaio Beatriz Almeida , Spergser Joachim , Rosengarten Renate , Marques Lucas Miranda , Chopra-Dewasthaly Rohini
Published: February 2024

Contagious agalactia (CA) is a serious multietiological disease whose classic etiological agent is Mycoplasma agalactiae and which causes high morbidity and mortality rates in infected herds. CA is classified as a notifiable disease by the World Organization for Animal Health due to its significant worldwide economic impact on livestock, primarily involving goat and sheep farms. The emergence of atypical symptoms and strains of M. agalactiae in wildlife ungulates reestablishes its highly plastic genome and is also of great epidemiological significance. Antimicrobial therapy is the main form of control, although several factors, such as intrinsic antibiotic resistance and the selection of resistant strains, must be considered. Available vaccines are few and mostly inefficient. The virulence and pathogenicity mechanisms of M. agalactiae mainly rely on surface molecules that have direct contact with the host. Because of this, they are essential for the development of vaccines. This review highlights the currently available vaccines and their limitations and the development of new vaccine possibilities, especially considering the challenge of antigenic variation and dynamic genome in this microorganism.

Authors: Várhidi Zsóka , Csikó György , Bajcsy Árpád Csaba , Jurkovich Viktor
Published: February 2024

Uterine disease is an intensely studied part of dairy cattle health management as it heavily affects many commercial dairy farms and has serious economic consequences. Forms of the disease, pathophysiology, pathogens involved and the effects of uterine disease on the health and performance of cows have already been well described by various authors. Lately, researchers’ attention has shifted towards the healthy microbiome of the uterus and the vagina to put emphasis on prevention rather than treatment. This aligns with the growing demand to reduce the use of antibiotics or—whenever possible—replace them with alternative treatment options in farm animal medicine. This review provides a comprehensive summary of the last 20 years of uterine disease research and highlights promising new areas for future studies.

Published: February 2024

The Volga River is the largest river in Europe in terms of basin area (1.36 mio. km2), length (3531 km), and water content (annual flow 254 km3). We conduct long-term water quality studies in the Volga headwaters: in the Upper Volga Lakes, the free-flowing section, as well as in the Ivankovskoye and Uglich Reservoirs. At the source of the river, the water is very soft, slightly mineralized, characterized by high color indicators (up to 400 degrees Pt-Co scale) and permanganate oxidation (60.3–72 mgO/L). In the Upper Volga Lakes, water mineralization increases to 110 mg/L, and the color of the water decreases significantly. In the Ivankovo Reservoir, higher concentrations of manganese and BOD5 are noted than in the Volga above Tver. Based on total phosphorus concentrations, the Upper Volga Reservoir (Lake Volgo) and the free-flowing section of the Upper Volga (from Selizharovo to Tver) belong to the “mesotrophic” class, and the Ivankovskoye Reservoir belongs to the “eutrophic” class. We characterize the Volga headwaters based on physico-chemical parameters “balanced” and discuss the relevance of “natural pollution”. Especially the free-flowing section comprises an important reference section for lowland rivers; thus, long-term monitoring of abiotic and biotic aspects is an important issue.

Melatonin is the main neuroendocrine hormone of the pineal gland. A distinctive feature of melatonin indole is its ability to regulate physiological processes related to the circadian rhythm. Numerous scientific data demonstrate the importance of melatonin in the development of organic and functional pathologies of the gastrointestinal tract (GIT), due to the close relationship between the hormone and intestinal structures. The paper presents the results of our study and shows dynamic variations in seasonal gradations of melatonin levels in patients with gastric and duodenal ulcers. The studies have shown that in patients with gastric and duodenal ulcers, the level of the hormone melatonin varied depending on the season. During the period of long daylight hours (spring and summer), the content of indole in the blood was ≥1 pg/ml, while during the period of minimal daylight (autumn and winter), the content of melatonin was ≤1 pg/ml. Therefore, if the melatonin level is less than 1 pg/ ml in spring and summer, and more than 1 pg/ml in autumn and winter, it can be concluded that an individual does not have peptic ulcer disease. Thus, the melatonin shift in the blood at different time limits relative to light illumination can be used as a laboratory biomarker of desynchronosis associated with the risk of developing acid-related diseases, in particular seasonal exacerbation of gastric and duodenal ulcers. Accordingly, revealing the causes and mechanism of development of seasonal exacerbation of peptic ulcer disease can help in early prediction and prevention of this nosology.
February 9 — Dentist Day in Russia

Published: February 2024

“A man is what he eats,” these words belong to the great Pythagoras. By these words he meant the connection between the origin of the eaten food and the spiritual development of an individual. In fact, a lot depends on the nature of nutrition, the quality of food supplied to the body and, of course, on the degree to which the body digests it. The digestion process does not begin in the stomach, but directly in the oral cavity as a result of mechanical processing of foods by the teeth and under the influence of the secretion of the salivary glands. That is why healthy teeth are the key to the normal functioning of the entire body. People should begin to take care of the condition of their teeth from early childhood, and not everyone’s favorite and often carelessly avoided dentists are called upon to help keep teeth in a healthy state.

Published: February 2024

Given the high theoretical capacity (1,675 mAh g−1) and the inherent affordability and ubiquity of elemental sulfur, it stands out as a prominent cathode material for advanced lithium metal batteries. Traditionally, sulfur was sequestered within conductive porous carbons, rooted in the understanding that their inherent conductivity could offset sulfur’s non-conductive nature. This study, however, pivots toward a transformative approach by utilizing diatom shell (DS, diatomite)—a naturally abundant and economically viable siliceous mineral—as a sulfur host. This approach enabled the development of a sulfur-layered diatomite/S composite (DS/S) for cathodic applications. Even in the face of the insulating nature of both diatomite and sulfur, the DS/S composite displayed vigorous participation in the electrochemical conversion process. Furthermore, this composite substantially curbed the loss of soluble polysulfides and minimized structural wear during cycling. As a testament to its efficacy, our Li-S battery, integrating this composite, exhibited an excellent cycling performance: a specific capacity of 732 mAh g−1 after 100 cycles and a robust 77% capacity retention. These findings challenge the erstwhile conviction of requiring a conductive host for sulfur. Owing to diatomite’s hierarchical porous architecture, eco-friendliness, and accessibility, the DS/S electrode boasts optimal sulfur utilization, elevated specific capacity, enhanced rate capabilities at intensified C rates, and steadfast cycling stability that underscore its vast commercial promise.

Breeding approaches for improvement of temperate fruit crops and nuts - a review
Authors: Wani Mohmmad Asif , Magray Aalia Farooq
Published: February 2024

Fruit breeding is an ancient technology with dynamic current technology and an exciting future (Janick and Moore, 1975, 1996).  In its broadest sense, fruit breeding refers to the purposeful genetic improvement of fruit crops through various techniques including selection, hybridization, mutation induction, and molecular techniques. Its origins trace to the domestication process in prehistory and antiquity, where useful species were chosen and cultivated, and improved by continuous selection (Janick, 2005, 2011). Much of the world fruit industry is still based on grower selection from chance seedlings as well as mutations (sports) and as a result many fruit species are characterized by a narrow germplasm base. Spontaneous hybridization between wild plants and cultivated clones was critical to the early domestication of fruits. The lengthy juvenile period and the large field space required to grow temperate fruits have imposed major limitations on conventional breeding and various molecular biological techniques have been employed to make fruit breeding easier. (Igarashi et al.2016). Marker-assisted selection (MAS) uses DNA markers to provide an early DNA-based evaluation of genetic performance potential of seedlings, with the aim of improving cost and/or genetic efficiency of seedling selection (Ru, et al., 2015). Transgenic technology has facilitated the development of fruit trees with resistance to fungal or bacterial diseases, improved fruit quality, or root stocks with better rooting or dwarfing ability. In recent years, new technologies for genetic improvement, such as transgrafting, and genome-editing, have emerged. (Mudge, et al. 2009; Jia and Wang 2014). Using these techniques, no foreign genes are present in the final product, and some of them show considerable promise for application to apple breeding. Furthermore, genome editing, by which only the target gene can be accurately modified, is emerging as a novel breeding technology. These new technologies will undoubtedly facilitate fruit breeding, and yield novel and attractive fruit cultivars.

The present study focuson the adsorption of hexavalent chromium with Sargassum myriocystum, algae and the outcomes of various parameters such as size of sorbent, contact time, temperature, sorbent dosage and agitating speed were enhanced with aid of response surface methodology. The maximum adsorption of hexavalent chromium in its optimized conditions were determined as solution temperature of 35oC, size of sorbent for 0.5284 mm 36 BSS mesh ,contact time (1 hour), agitating speed (50 rpm) and sorbent dosage (4.309 g).The utmost removal was 99%  . Isotherm studies revealed that Langmuir model is fitting the algae with a hexavalent chromium uptake of 61.5384mg/g. Thermodynamic study revealed that it is endothermic in nature and values of Gibb’s free energy, enthalpy and entropy change are in accordance. The sorbents were characterized with FTIR and SEM. FTIR studies revealed the presence of a few functional groups like carboxylic acid, amino and hydroxyl in hexavalent chromium adsorption. Pseudo I order kinetics are in accordance for this process. From above studies it can be concluded that Sargassum myriocystum had good removal capacity for hexavalent chromium from fabricated solutions.

Padrões corretos de movimento são de fundamental importância na vida e no esporte de crianças e adolescentes. Este estudo teve como objetivo verificar a existência de diferenças estatisticamente significativas dos padrões de movimento entre crianças praticantes Futebol e Educação Física escolar. Foi utilizado o método comparativo, sendo a pesquisa de caráter quantitativo descritivo. Para obtenção dos dados utilizamos o protocolo TGMD-2 (Test of Gross Development – Second Edition), elaborado por Ulrich (2000). Com os dados coletados fizemos a tabulação com a utilização do software Easy TGMD 2 v 1.0 proposto por Souza (2008), assim determinamos os padrões de controle de objetos, locomotores e geral, conforme o desempenho dos participantes na realização das tarefas que compõem o teste TGMD-2. Utilizando o teste de Mann-Whitney verificamos às possíveis diferenças entre os grupos de participantes, quanto ao padrão locomotor, padrão de controle de objetos e padrão motor geral. Aplicamos a estatística descritiva para a obtenção das variáveis idade cronológica, idade locomotora, atraso locomotor, idade controle de objetos, atraso controle de objetos e quociente motor, levando em conta a média e o desvio padrão. Com essa pesquisa buscamos mostrar se houve ou não diferença estatisticamente significativa entre os dois grupos nas variáveis pesquisadas. Com base nos resultados que foram obtidos, podemos dizer se foi possível afirmar que a prática extracurricular do futebol ou só a frequência nas aulas de educação física, exercem influência positiva no desenvolvimento motor das crianças participantes, e se contribui para a melhora dos padrões motores e desenvolvimento correto e saudável dos mesmos.

A ideia deste trabalho encontra amplo sentido na própria realidade que se instalou entre nós, alavancada pela virtualidade efêmera das relações estabelecidas em redes sociais, onde a notícia falsa (fake news) encontrou terreno fértil, entre elas as inverdades científicas. O objetivo foi verificar a existência de modelos mentais capazes de traduzir o olhar de estudantes ao mundo ao seu redor, em especial àquilo que ele vê como fenômeno ou evento científico, e se a explicação deste modelo mental pelo estudante utiliza elementos conceituais da própria ciência. A coleta de dados se deu por meio de resposta à questão “como percebo a ciência inserida na minha vida?”. Doze alunos do terceiro ano do ensino médio de três escolas diferentes elaboraram modelos para respondê-la. As alternativas dadas para o delineamento dos modelos foram: desenho ilustrativo, mapa ou esquema explicativo, texto, fotografias com legendas explicativas, ou vídeo narrado pelo próprio aluno. Seis gravaram suas respostas em forma de vídeo (todos transcritos para análise), três responderam apenas textualmente e outros três utilizaram desenhos e textos, todos analisados com base em quatro categorias formuladas a partir da teoria de modelos mentais de Philip Nicholas Johnson-Laird, teórico principal deste trabalho. Os resultados mostraram que o lugar do conhecimento científico alicerçado na escola permanece sólido frente ao movimento de produção de mentiras da atualidade, e mesmo os modelos perceptuais, portanto menos conceituais, sobre como os alunos percebem a presença da ciência em suas vidas, não corroboram com inverdades científicas.

A Organização Mundial da Saúde (OMS) relata que mais de 350 milhões de pessoas enfrentam depressão globalmente, sendo pelo menos 5% da população diagnosticada com o distúrbio. A depressão cresceu 18,4% globalmente de 2005 a 2015, com prevalência de 4,4% mundial e 5,8% no Brasil. Ansiedade e depressão são comuns, podendo indicar transtornos psiquiátricos que demandam tratamento. Fitoterápicos têm surgido como alternativa aos medicamentos alopáticos, oferecendo menor incidência de efeitos colaterais e custos mais acessíveis. Estudos destacam o potencial ansiolítico de plantas como camomila, erva-cidreira e mulungu, enquanto extratos de Passiflora incarnata demonstram efeitos ansiolíticos significativos. O estudo busca analisar abrangentemente a literatura sobre fitoterápicos no tratamento de distúrbios psiquiátricos. A pesquisa consistiu em uma revisão bibliográfica narrativa que analisou a literatura publicada sobre o uso de plantas medicinais no tratamento de distúrbios psiquiátricos. Para a busca, foram utilizados os bancos de dados Scielo, Pubmed e LILACS, com descritores como plantas medicinais, fitoterapia, psiquiátrico e TAG, incluindo termos correspondentes em inglês. A análise abrangeu artigos de 2016 a 2022, totalizando 24 artigos incluídos no estudo. Os estudos oferecem uma visão abrangente das propriedades medicinais de várias plantas, evidenciando seu potencial terapêutico em condições relacionadas à ansiedade, depressão e estresse. A abordagem integrativa, que explora os recursos da natureza, contribui para ampliar as opções terapêuticas disponíveis na área de saúde mental. As observações enfatizam a diversidade de plantas medicinais e suas possíveis aplicações como agentes ansiolíticos, antidepressivos e sedativos. Contudo, é crucial considerar que a eficácia e segurança dessas plantas podem variar, destacando a necessidade de mais pesquisas para uma compreensão completa de seus benefícios terapêuticos.

Introdução: A falta de informação sobre biossegurança e comportamento em ambiente de internação para familiares cuidadores de pacientes pediátricos pode contribuir para aumentar os riscos de contaminação acidental em ambiente hospitalar. Objetivo: Descrever a percepção de familiares cuidadores de pacientes pediátricos sobre biossegurança e comportamento em ambiente hospitalar. Metodologia: Estudo prospectivo, descritivo com abordagem quantitativa onde a coleta de dados se deu através de testes escritos, antes e após orientações in locu, ou seja, beira leito, para avaliar o conhecimento destes sobre biossegurança e comportamento em ambiente de internação. Resultados: No período foram entrevistados 104 familiares cuidadores, sendo que 39 (37,5%) eram acompanhantes de pacientes com doenças infecto contagiosas já com tratamento em curso e 65 (62,5%) da clínica para pacientes pediátricos em investigação por apresentarem síndrome respiratória aguda grave-SRAG. Esses familiares cuidadores tinham idade entre 18 a 60 anos com ensino médio completo (64,6%). Um número bem expressivo deles (70,7%) eram mães dos pacientes e 15,5% informou que tinham apenas o cônjuge como apoio para realização de permutas/trocas. A Zona Norte da cidade de Manaus foi o endereço onde a maioria (26,2%) morava. Um grande número dos entrevistados (60,5%) não tinham entendimento sobre regras de biossegurança e que a maior dúvida era o motivo pelo qual não podiam colocar seu paciente no berço de outra criança (34,6%). Após treinamento houve 100% de acerto em todas os questionamentos relacionados a biossegurança e comportamento em ambiente hospitalar. Conclusão: toda e qualquer exposição desnecessária a riscos existentes em ambiente hospitalar é amenizada na presença de orientações.
