The Metacognitive and Exploratory Use of the Concept Map for Thematic Art History Papers in the Survey Course
Authors: Cempellin Leda
Published: November 2024

This article examines how the introduction of pedagogical interventions in the art history survey class, made by using concept maps beyond an initial brainstorming phase and rather as an active-learning strategy in aid to developing thematic papers, impacts students' perception of their usefulness. The qualitative and quantitative data gathered included two questionnaires, one submitted periodically throughout the semester and one after the concept map and term paper were completed. Additionally, this study presents a visual analysis of three sample sets of students' concept maps to illustrate the levels of deep, surface, and non-learning. The results reveal that assigning students the task of developing the concept map and the paper in tandem throughout the semester presents some pros and cons. By using concept maps, students reflect more deeply on the nature of connections between two ideas, on the process of narrowing down the main theme, and on the overall structure of the concept map. However, students' perception of the concept map's usefulness beyond an initial brainstorming phase is diversified, and the sets of concept maps developed produce mixed results relative to surface learning, deep learning, and non-learning. The limitations of such use of concept maps include possible correlations between learning and motivation.
Visual Diaries: Towards Art History as Storytelling
Authors: Patel Alpesh Kantilal
Published: November 2024

This essay examines variants of what I refer to as "visual diaries"  or thinking through images and written or oral language  as important "worldmaking" exercises, essential for students of color, women, sexual minorities, or other marginalized subjects. I provide my reflections on assigning this dynamic and student-centered, practice-based assignment in my contemporary art courses at a Hispanic-serving institution (HSI) of higher education and a summer art residency program unaffiliated with a university. Besides my reflections on my pedagogy, I also share student feedback from unsolicited testimonials and answers to questionnaires. I argue that visual diaries transform students into veritable storytellers of art history. Thinking of art history as storytelling empowers students to create the histories they deserve and may not see in the classroom. There can always be another story, another way of looking at seemingly the same set of assumptions (or "facts").

Published: November 2024

O aumento na produção de alimentos de forma sustentável é fundamental para o contínuo desenvolvimento da humanidade. Para que isso ocorra, processos que contribuam para uma maior eficiência no uso da água e de fertilizantes devem ser aprimorados. O objetivo do presente estudo foi determinar a produtividade, índices de aproveitamento de N e o retorno econômico da adubação nitrogenada para o café arábica de montanha, na fase inicial de produção, bem como as modificações nas características químicas do solo decorrentes da aplicação de doses crescentes de N, na forma de ureia comum ou protegida, em plantio convencional, adensado ou superadensado. Foram montados dois experimentos variando o espaçamento de plantio do café arábica e as doses de N aplicadas como ureia comum ou protegida. Foram determinados a produtividade de café beneficiado, características e propriedades químicas do solo e índices de aproveitamento de N, sendo calculados ainda a renda bruta por hectare e o retorno econômico da adubação nitrogenada. Foi possível concluir que o adensamento de plantio do café aumenta, de forma acentuada, a produtividade e o aproveitamento do fertilizante nitrogenado na primeira colheita consistente, sem reduzir a produção por planta. A ureia com inibidor de urease é mais eficiente do que a comum em espaçamentos de plantio mais abertos. Elevada renda bruta nas primeiras colheitas é obtida no plantio mais adensado e com maior dose de N, mas o maior retorno econômico por unidade investida em fertilizante nitrogenado ocorre em plantio mais adensado ao se aplicar menores doses de N.

Authors: Silva Flávia Gomes da , Maia Rafael Trindade , Jimenez Horace José , Moraes Filho Rômulo Maciel de , Silva Gheysa Coelho
Published: November 2024

The subfamily Papilionoideae (Fabaceae) has approximately 32 tribes, the Phaseoleae tribe being the largest, with about 90 genera and 1,600 species, distributed in seven subtribes. This tribe has a great diversity of species of economic importance as a source of human and animal food. They also stand out for the presence of the Bowman-Birk-type protease inhibitor (BBI), which is well recognized for its insecticidal action. Thus, the objectives of this research were to characterize, compare and identify conserved domains in BBI sequences from different species of the tribe Phaseoleae; perform phylogenetic analysis; develop three-dimensional models and molecular docking. 23 BBI sequences from Phaseoleae species were analyzed. Physicochemical parameters, presence of signal peptide cleavage sites, domain identification and estimation of functional effects were performed by ProtParam, TOPCONS, Prodom and SNAP2, respectively. The MEGA 7 program was used to construct the phylogenetic tree using the Maximum Likelihood method. The prediction, evaluation and validation analyzes of the tertiary structure of the models were obtained by the GalaxyTBM, UCSF Chimera, SAVES and ProSA-web servers and the ClusPro-2.0 SPPIDER servers for the molecular docking analysis. For all species, the isoelectric point showed a slightly acidic character. Two functional domains have been identified in the BBI sequences. From the molecular docking analysis it was possible to show interface residues. Cluster analysis was consistent with the most recent phylogenies of the analyzed species.

Os testes de vigor são essenciais na determinação da qualidade das sementes, fornecendo dados cruciais para sua gestão. Esse trabalho teve como objetivo avaliar a eficácia do teste de deterioração controlada na avaliação da qualidade de lotes de sementes de Citrullus lanatus (Thumb.) Matsum & Nakai. Foram utilizados quatro lotes da cultivar Crimson Sweet, seguindo um delineamento experimental fatorial 4 x 2 x 2 x 2 (quatro lotes, duas temperaturas, duas umidades da semente e dois tempos de exposição) e quatro repetições por tratamento. Os lotes foram caracterizados inicialmente quanto à germinação, primeira contagem de germinação, envelhecimento acelerado, condutividade elétrica, emergência em campo e índice de velocidade de emergência. Para o teste de deterioração controlada, as sementes foram ajustadas para teores de água de 18% e 24% e submetidas ao banho-maria, a temperaturas de 41°C e 45°C, com exposição de 48 e 72 horas. Os resultados indicaram que o teste de deterioração controlada foi eficaz na avaliação da qualidade dos lotes de sementes de melancia. Notavelmente, as combinações mais eficazes na avaliação do vigor foram aquelas em que as sementes foram submetidas a um teor de água de 18%, junto com temperaturas de 41°C ou 45°C, por um período de 48 horas. Os resultados destacam a relevância do teste de deterioração controlada na avaliação confiável da qualidade das sementes de melancia, especialmente quando realizado sob condições específicas de teor de água e temperatura. Possibilitando uma decisão adequada no manejo dos lotes de sementes.

Published: November 2024

High-density pecan orchards may improve production and mitigate shading issues with the use of pruning. The period in which it is carried out may influence shoot vigor, branch drying, fructification and fruit quality. This study aimed at evaluating vegetative growth, production and fruit quality by conducting hedge and central pruning in a high-density pecan orchard for two cycles. The cultivar Pitol 1 was subject to the following treatments, which were evaluated in two cycles: no pruning, postharvest hedge pruning, dry hedge pruning, postharvest central pruning and dry central pruning. Variables under analysis were shoot growth, dry branches, production efficiency and fruit quality. Postharvest pruning decreased vigor and, consequently, shoot growth. The number of dry branches decreased after central pruning in both pruning periods whereas hedge pruning did not mitigate the problem. Production and production efficiency just increased after pruning in the second cycle. Fruit borne by trees that were subject to postharvest pruning got heavier but only the ones borne by trees subject to central pruning got larger. Central pruning resulted in lighter and yellowish kernels. Postharvest pruning is an alternative solution to get less vigorous shoot in high-density pecan orchards and its response is similar to the one of the winter pruning regarding reduction in dry branches. Postharvest central pruning is the treatment that increases fruit quality more than the others, in terms of size and weight.
Bioethanol preparation and separation from pineapple peel upon combining fermentation and pervaporation through biochar-containing PDMS membranes
Authors: Nonato Sabrina de Matos , De Souza Figueiredo Katia Cecilia
Published: November 2024

Ethanol is an alternative to replace the fossil fuels. Different sources have been studied to produce second generation ethanol, such as food waste. The goal in this work was the investigation of pineapple peel as sugar source for ethanol production by fermentation and its separation from the broth. Sugar from pineapple peel was extracted with water and the rich phase was pre-treated with filtration in cloth, and a conventional filter (14 µm). Then, the filtrate was fermented to ethanol using Saccharomyces cerevisiae. The fermentation broth was fed to a pervaporation system containing polydimethylsiloxane membranes, with 0 and 2 wt% biochar from pineapple waste, in order to purify bioethanol and remove it from the broth. The yield of bioethanol in fermentation broth was 88%, after 24 hours. Pervaporation tests revealed higher flux and selectivity for non-containing biochar membranes, showing values of 120 g/m2h and 1.0 v/v% of ethanol in permeate. The results showed the potential of the use of pineapple waste as the sugar source for biofuels such as bioethanol.

Schinus terebinthifolius é amplamente usada na medicina tradicional brasileira por suas propriedades terapêuticas, como ação antimicrobiana, antioxidante e antifúngica. Embora essas propriedades sejam bem estudadas, a influência da sazonalidade ainda não é totalmente compreendida. Assim, este estudo visa avaliar o efeito da sazonalidade no teor de compostos fenólicos, nas atividades antioxidante e antimicrobiana das folhas da planta. As amostras foram coletadas em Salvador, Bahia, em julho de 2021 e janeiro de 2022, maceradas em metanol e particionadas em hexano e acetato de etila, originando os extratos hexânico (STH) e acetato de etila (STA). Fenóis totais, flavonoides e taninos foram determinados pelos métodos de Folin-Ciocalteau, AlCl3 e FeCl3, respectivamente. A atividade antimicrobiana foi avaliada pelo método da microdiluição em caldo e a atividade antioxidante pelo método do sequestro de radicais livres DPPH (1,1-difenil-2-picril-hidrazina). Os resultados obtidos confirmaram a atividade antioxidante dos STA inverno e verão e STH inverno. As concentrações inibitórias (IC50) foram de 0,028mg/mL e 0,163mg/mL para STA inverno e STA verão, respectivamente. Estas frações foram as que apresentaram os maiores teores de fenóis e flavonoides totais. As frações STH, apenas a de inverno apresentou atividade com IC50 0,875 mg/mL. Com relação à atividade antimicrobiana, todos os extratos da estação verão apresentaram atividade contra 4 das 5 cepas bacterianas testadas. STA verão demonstrou atividade bactericida e bacteriostática, enquanto STH inverno mostrou atividade bacteriostática. Com relação aos fungos testados, o STH verão apresentou atividade fungiostática e fungicida frente a Candida albicans e C. glabrata.
Resolução numérica de equações diferenciais parciais fracionárias usando o método pseudo-espectral de Legendre e o método de Adams
Authors: Lima William Júnio , Lobato Fran Sérgio
Published: November 2024

O estudo de equações diferenciais parciais fracionárias configura-se como um tema de grande importância em diferentes áreas da ciência e engenharia. Isto se deve ao grande número de aplicações que podem ser desenvolvidas a partir deste tipo de modelo. Do ponto de vista matemático, a ordem fracionária que caracteriza cada contribuição diferencial pode ser interpretada como um parâmetro adicional e que pode ser ajustado para uma dada aplicação. Resolver analiticamente ou numericamente tais modelos fracionários representa uma tarefa complexa, visto que a grande maioria dos modelos são inerentemente não lineares. Neste contexto, o presente trabalho tem por objetivo estender o método pseudo-espectral de Legendre para o contexto fracionário. Além disso, combinar a abordagem proposta com o tradicional Método de Adams fracionário. A primeira abordagem é empregada para transformar o modelo original em um conjunto de equações diferenciais ordinárias fracionárias no tempo, sendo o mesmo integrado considerando o Método de Adams fracionário. Para avaliar a metodologia proposta, alguns estudos de caso são resolvidos e os resultados numéricos são comparados com as soluções analíticas. Os resultados obtidos demonstram que a metodologia proposta se configura como uma interessante estratégia para resolver este tipo de problema.

Published: November 2024

O tipo de recurso alimentar disponível no ambiente pode influenciar no comportamento das colônias de formigas, além disso, os hidrocarbonetos cuticulares (HC’s) são compostos importantes para o reconhecimento de companheiras de ninho e sua composição pode ser influenciada por diversos fatores entre eles e a dieta. Nossa hipótese é de que operárias de uma mesma colônia de Odontomachus bauri, quando submetidas à variação de dieta, podem sofrer mudança na composição de HC’s de sua cutícula, que por sua vez, levaria a uma mudança em seu padrão de reconhecimento de companheiras de ninho. Para isto, dez colônias foram subdivididas em grupos controle e experimentais, os grupos controle receberam dieta padrão (mel e Cornitermes cumulans), e os experimentais variou-se entre mel e melaço de cana, Tenebrio molitor e C. cumulans. Após isso foram realizados encontros induzidos entre os grupos das diferentes dietas para avaliar a tolerância entre as companheiras de ninho. A composição química cuticular foi analisada usando cromatografia gasosa acoplada à espectrometria de massas, e análises estatísticas foram aplicadas para determinar diferenças significativas nos comportamentos e na composição química. Não foram observadas agressividade, mas os reconhecimentos indicaram diferenças significativas nos tempos de antenação entre os grupos, além disso, a análise do perfil de HC’s confirmou variações significativas nos tratamentos. Conclui-se que a variação na dieta influencia o perfil de HC’s de O. bauri, causando estranhamento entre companheiras de ninho. Desta forma, nossos resultados evidenciam a capacidade da dieta em modular o perfil químico e comportamental da formiga O. bauri.
Mitigating hemoglobin‐induced nephropathy: ApoHb‐hp protection of podocytes
Authors: Lucas Daniela , Munoz Carlos , O'Boyle Quintin , Pires Ivan S. , Palmer Andre F. , Cabrales Pedro
Published: November 2024

This study investigates hemoglobin (Hb)‐induced kidney injury and the protective role of the ApoHemoglobin‐Haptoglobin (ApoHb‐Hp) complex against heme and Hb damage. Hb facilitates oxygen (O2) delivery but poses challenges outside red blood cells (RBCs) due to toxic Hb and heme mechanisms. These are managed by binding to serum proteins like Haptoglobin (Hp) and Hemopexin (Hpx). During hemolysis, depletion of Hp and Hpx leaves tissues vulnerable to Hb and heme. To address this, we developed the ApoHb‐Hp complex, based on Apohemoglobin, which is produced by removing heme from Hb, conjugated with Hp. This complex acts as a dual scavenger for Hb and heme, preventing tissue damage. Our findings demonstrate that ApoHb‐Hp significantly protects MPC5 podocytes from Hb‐induced damage. Fluorescent staining showed a higher percentage of nephrin‐positive cells in the ApoHb‐Hp group, and MTT assays revealed enhanced cell viability compared to Hb alone. Additionally, ApoHb‐Hp reduced reactive oxygen species (ROS) production, with the Hb group exhibiting significantly elevated ROS levels. The ApoHb‐Hp complex mitigated the depletion of protective mechanisms, as shown by significant increases in superoxide dismutase (SOD) and glutathione (GSH). Moreover, ApoHb‐Hp treatment reduced the activation of the NLRP3 inflammasome signaling pathway and inflammatory cytokines IL‐1β and IL‐18. These findings underscore the therapeutic potential of ApoHb‐Hp in mitigating Hb‐induced renal damage by preserving podocyte viability and reducing oxidative stress. Overall, ApoHb‐Hp maintained protective mechanisms depleted otherwise by Hb. These findings highlight ApoHb‐Hp's potential as a therapeutic agent against Hb‐induced renal damage, offering insights into its mechanisms and implications for treating conditions involving hemolysis.

Correlation analysis of AVPR1a and AVPR2 with abnormal water and sodium and potassium metabolism in rats
Authors: Sun Kun , Qiu Yingzhu , Sun Yao
Published: November 2024

In clinical practice, an increasing number of patients exhibit concurrent cardiac and renal dysfunction, known as “cardiorenal syndrome,” where each condition exacerbates the other, resulting in poorer patient prognosis. Fluid and sodium retention can lead to excessive fluid overload in the body; therefore, correcting fluid and sodium metabolic disorders is crucial for alleviating patient symptoms. This study was to investigate the abnormalities in water and sodium metabolism, as well as the expression levels of arginine vasopressin receptor 1a (AVPR1a) and arginine vasopressin receptor 2 (AVPR2), in a rat model of chronic renal failure–chronic heart failure (CRF–CHF). One hundred male Sprague-Dawley rats were randomly assigned into four groups: the CG group (normal feeding), the CRF group (3/4 nephrectomy using a “two-step surgical method”), the CHF group (subcutaneous injection of isoproterenol at 100 mg/kg), and the CRF–CHF group (3/4 nephrectomy followed by a subcutaneous injection of isoproterenol at 100 mg/kg 1 week later). 4 weeks post-surgery, urine and blood samples were collected to measure 24 h urinary protein, sodium, and potassium levels. Serum creatinine (SCr) and blood urea nitrogen (BUN) levels were determined using assay kits. Left ventricular end diastolic pressure (LVEDP) and left ventricular systolic pressure (LVSP) were measured via left ventricular catheterization. The heart was weighed to calculate the left ventricular weight to body weight ratio (LVW/BW). The renal cortex and medulla were isolated to assess the relative mRNA and protein expression levels of AVPR1a and AVPR2. Compared to the CG group, the CRF and CRF–CHF groups exhibited significantly elevated levels of 24 h urinary protein, SCr, BUN, and relative expression levels of AVPR1a and AVPR2 in the renal cortex and medulla. The CHF and CRF–CHF groups showed significant increases in LVEDP and LVW/BW (P < 0.05). Additionally, compared to the CG group, the other three groups had significantly increased urinary sodium and blood potassium levels, and significantly decreased urinary potassium and blood sodium levels (P < 0.05). Compared to the CRF and CHF groups, the CRF–CHF group exhibited significantly higher levels of 24 h urinary protein, SCr, BUN, and relative expression levels of AVPR1a and AVPR2 in the renal cortex and medulla, along with significantly increased LVEDP and LVW/BW, significantly reduced LVSP, significantly increased urinary sodium and blood potassium levels, and significantly decreased urinary potassium and blood sodium levels (P < 0.05). Rats with CRF–CHF experienced exacerbated renal and cardiac failure, characterized by significant disturbances in water and sodium metabolism and abnormal expression of AVPR1a and AVPR2.
Effectiveness of a Pop-Up Story-Based Program for Developing Environmental Awareness and Sustainability Concepts among First-Grade Elementary Students
Authors: Mohamed Dalia Abdelwahed , Ali Asma Margeni Hussien
Published: November 2024

The study aims to assess the effectiveness of a pop-up story-based program in fostering environmental awareness and sustainability among first-grade elementary students. Using a quasi-experimental design, the study included experimental and control groups, each consisting of 56 students, randomly assigned to two groups: 28 in the experimental group and 28 in the control group. The experimental group participated in a 12-session program on environmental awareness and sustainability. After confirming the test’s validity, reliability, and appropriate difficulty and discrimination indices, both groups took a pictorial test covering four key concepts: water and air pollution, recycling, sustainable agriculture, and manufacturing. The results showed statistically significant differences at the 0.05 level between the post-test scores of the control and experimental groups regarding environmental awareness and sustainability concepts, in favor of the experimental group. This demonstrates the effectiveness of the pop-up story-based program in enhancing environmental awareness and sustainability concepts among first-grade students. The study recommends integrating environmental awareness and sustainability topics into teacher training programs at education colleges.
Study on the influence mechanism of land use on carbon storage under multiple scenarios: A case study of Wenzhou
Authors: Quan Wei , Huang Xuankai , Xu Gang , Hao Jun , Lv Kangting , Jiang Xiaomin
Published: November 2024

Based on the perspective of conflict of interest between low-carbon ecology and economic and social development, this study explores the change mechanism of land use cover change (LUCC) and carbon storage (CS) in the context of “Dual-Carbon” goal and territorial spatial ecological governance, which is of great significance to optimize the construction path of “Dual-Carbon” goal and formulate low-carbon, ecological, high-quality, and sustainable economic and social policies in the urban areas. An integrated framework based on the System Dynamics model, the Patch Generation Land Simulation model, and the Integrated Valuation of Ecosystem Services and Trade-offs model was constructed to dynamically simulate the LUCC demand and CS of Wenzhou under four scenarios in 2035, and to analyze the spatial evolution mechanisms of LUCC and CS. The main results of the study show that in the Natural Development Scenario (NDS) and High-speed Urbanization Scenario (HUS), the expansion mechanism is similar, and the area of woodland decreases greatly, which is mainly caused by the rapid expansion of construction land and cultivated land. Under Low-carbon and High-quality Development Scenario (LHDS) and Ecological Safety Governance Scenario (ESGS), woodland and grassland increased significantly, mainly because low-carbon and ecological governance policies strengthened ecological land protection and limited construction land control. By 2035, the prediction results show that LHDS has the highest CS (2.231 × 105 kt), followed by ESGS (2.226 × 105 kt), NDS (2.191 × 105 kt), and HUS (2.142 × 105 kt). The range of increase and decrease was 0.189, −0.149, −1.676, −3.692%, and only in LHDS, CS increased by 42.05 kt. Therefore, in order to achieve the “Dual-Carbon” goal, Wenzhou needs to prioritize the combination of LHDS and ESGS to formulate relevant policies.
Conditional Right to Child Education in Nigeria: Punishing the Child for the Parents’ Sins
Authors: Jimoh Mujib
Published: November 2024

The question this paper seeks to answer is: can the refusal of parents to pay taxes be the basis for the State to deny their child’s right to education? In ISH-16, the High Court of Lagos State, Nigeria, answered the question in the affirmative. This paper seeks to answer otherwise. It argues that human rights theory cannot support the Court’s reasoning. However, because the paper is more legal than philosophical, it neither attempts to give a ‘full’ philosophical account of human rights nor discusses the ‘best’ theory that can support its thesis. Instead, the paper adopts Williams’ Phenomenological Conclusions on human rights and the Kin Punishment Theory to assert its claim. First, the paper argues that from Williams’ Phenomenological Conclusions that P (a State) which owes Y (the child) X (the right to education) and must procure X for Y, the parents’ duty to pay taxes to the State finds no place in those conclusions. Second, the paper posits that the Kin Punishment Theory, a rule of customary international law, prohibits the kin – no matter how close or grave the crime is – from being punished for the sin of a close relative. Human rights theory considers the desert basis for punishing the kin of the offender to be ‘zero.’ The paper lays three premises: (1) that human rights attach to personhood; (2) that a child is a separate person who has a legal personality since human rights law has detached the child from patria potestas; and (3) that requiring a condition (tax payment) from the parents before their child can enjoy the right to education is a punishment. From these premises, the paper concludes that punishing the child (by denying them their right to education) because their parents (other persons) refuse to pay tax violates the Kin Punishment Theory.

Idiopathic central precocious puberty (iCPP) is the most common cause of precocious puberty in girls. However, research on the psychological outcomes of iCPP girls is limited. To evaluated the psychological characteristics in iCPP girls in comparison to prepubertal girls throughout the first diagnosis and six-month follow-up period.

Methods

Eighty-five girls, age 6–8 years, and their caregivers were enrolled to the prospective cohort study. Three Thai-standardized questionnaires were used as psychological assessment tools, including Children’s Depression Inventory (CDI), Parent Screen for Child Anxiety Related Disorders (SCARED) and Parent-Strengths and Difficulties Questionnaire (SDQ).

Results

Forty-six iCPP and 39 prepuberty girls were enrolled at baseline. No significant differences in psychological and behavioral problems between iCPP and prepuberty girls. However, the iCPP group exhibited a significantly higher proportion of “risk and problem” for emotional problems compares to the prepuberty group (7 vs. 0, p=0.01) while the prepuberty group exhibits the significantly proportion of “risk” for peer problems (6 vs. 0, p=0.007). At baseline, twelve percent of iCPP girls exhibited depression and mean CDI score was 8.1 ± 7.2 and 3.7 ± 2.3 (p=0.007) in iCPP and prepuberty group, respectively. At the 6-month follow-up, there was no significant difference in psychological outcomes between two groups.

Conclusions

There were no significant differences in psychological and behavioral problems in iCPP girls compared to prepubertal girls. However, the higher prevalence of emotional problems and depression observed in iCPP girls constitutes significant psychological issues that necessitate close monitoring.

The intrinsic dielectric properties of Mediterranean bio-composites
Authors: AL-Oqla Faris M. , Nawafleh Nashat
Published: November 2024

The environment is seriously threatened by the growing use and disposal of technological products since most of them include non-biodegradable components. One approach to reduce environmental impact of electronic devices is to use biodegradable electronic components derived from natural fibers like protein and cellulose. Actually, a lot of research has been done on the viability of producing electronic components out of materials obtained from natural fibers. Their inclusion of several changeable functional categories is another benefit. Dielectric materials are one of the several necessary and commonplace parts of technical devices. A thorough study on the varieties of natural fibers used to make dielectric materials and their electrical properties would be beneficial in selecting the appropriate fibers and conditions for certain applications. To make full use of new natural composite materials in growing sectors, their electric properties have to be examined. However, along with polypropylene, four different kinds of natural lignocellulosic fibers will be discussed in this work: black pepper, sumac, pomegranate, and lemon – as case studies. In specific, over a frequency range of 1 KHz to 4 MH, the AC conductivity and dielectric constant of the produced samples were measured using the method of parallel plate capacitors. After that, given the performance of sisal fibers, a comparison between them and a sisal natural fiber (a non-Mediterranean variety) will be made.

Sandra Beckett (2012) dedicated her seminal study to crossover picturebooks, which are equally interesting to older and younger recipients, i.e. to the crossover audience of children and adults. Intergenerational encounters in children’s literature and been studied as a form of intergenerational play that is beneficial for readers as players, regardless of their individual age. Picturebook creators use various strategies to incorporate crossover content and appeal to readers of different generations. This paper focuses on two kinds of such strategies: intertextuality which draws on historical and cultural source texts, and on intergenerational jokes. These are clarified by using examples from Emily Gravett’s picturebook The Rabbit Problem (2009).

Published: November 2024

The paper presents the selected results of a research study of self-efficacy among students of teacher training for primary schools concerning education on puberty by comparing the Czech Republic and Croatia. The research was carried out as part of a student grant competition at Palacký University Olomouc1. Puberty is a significant element of sexuality education (Standards for Sexuality Education in Europe, 2010) which represents an important aspect in comprehensive education of children. It is important to prepare for this period in a timely and adequate manner, and this requires acquiring relevant knowledge. Primary school teachers must be prepared for puberty education in professional terms and in terms of their personality. The authors analysed the opinions about personal readiness of future primary school teachers in the didactic dimension of education which included the knowledge of the comprehensive definition of puberty; knowledge of basic topics of puberty education; knowledge of the goals of puberty education; respect for the humanizing aspects of puberty education; application of ethical principles in puberty education; selection of specific methods in puberty education; application of didactic approaches in puberty education and application of specific forms in puberty education. The results of the research study revealed how students (future teachers) felt with regard to being prepared for education on puberty in terms of some didactic dimensions, and whether they were sufficiently prepared for education in this specific area.

This study focuses on the effectiveness of a new substance in stabilizing paper information carriers – hydrotalcite applied to the paper in a partially polar environment. The effect of modification on the stabilization of paper during accelerated aging was investigated by measuring chemical (surface pH, rate of glycosidic bond cleavage), mechanical (coefficient of the relative increase of the lifetime for folding endurance), optical (colorimetry – CIE L*a*b*), and spectral (FTIR) properties. Three types of hydrotalcites differing in composition, particle size, and preparation conditions, were tested and compared. After the modification, all the properties of acidic test papers improved. The most promising type of hydrotalcite was prepared under the nucleation action of citric acid. The atomic ratio of Mg2+ to Al3+ of this hydrotalcite was equal to 5. Modification by this hydrotalcite led to an increase in surface pH by 1.3 to 2.7 units.

Role of skill lab training in anaesthesiology residency program
Authors: Lambe Abhinav , N Shetti Akshaya
Published: November 2024

Skill lab training plays an increasingly vital role in the residency programs of anaesthesiology, offering a controlled, hands-on learning environment where residents can enhance their technical proficiency, clinical judgment, and decision-making skills. This review highlights the value of simulation-based education in developing essential competencies such as airway management, regional anaesthesia, and crisis response in high-risk scenarios. By allowing residents to practice and refine techniques without jeopardizing patient safety, skill labs bridge the gap between theoretical knowledge and clinical application. Moreover, they provide opportunities for standardized training and immediate feedback, fostering continuous improvement. Integrating skill lab training into anaesthesiology residency programs has been shown to improve procedural confidence, reduce errors, and enhance patient outcomes. This article explores the effectiveness of skill lab training in accelerating skill acquisition, addressing training gaps, and preparing residents for real-world challenges in anaesthesia practice.

Authors: Ingelmo MD, PhD Ildefonso Ingelmo , Suay MD PhD Ricardo Navarro
Published: November 2024

Explosions are physical, chemical or nuclear reactions that produce a rapid release of enormous amounts of energy (mechanical, kinetic, radioactive, etc.). The chemical explosion is produced by the molecular breakdown of the elements that make up the explosive device. It is an oxidation-reduction process without the intervention of any gas (oxygen) that generates a powerful blast wave. Its harmful effect on living beings and destructive effect on nature is included in the generic term of traumatic injury by blast wave. The categories of explosion by explosive device are: combustion, deflagration and detonation. Explosive devices are classified as high power and low power. The former cause a detonation and the latter a deflagration. Traumatic injury, both physical and psychological, by blast wave is multimodal and its didactic taxonomy refers to the predominant etiological factor. The physical aspects of the explosion and the blast wave are the subject of this narrative review.
Biophysics and physiopathogenesis of blast wave traumatic injury. Narrative review Part II.

Published: November 2024

The harmful effect of chemical explosions on living beings and the destructive effect on nature are encompassed by the generic term of traumatic injury caused by blast waves. Nowadays, blast injuries are not exclusive to the military field, since in the civilian environment both accidental explosions (domestic and industrial) and intentional explosions (urban terrorism and asymmetric and/or hybrid warfare) have increased considerably. Blast injuries include both physical and psychological trauma. The pathophysiology of tissue damage caused by the blast wave is different from that of conventional civilian trauma (precipitation, traffic accidents, and others).

The blast wave produces a multimodal injury (different etiological factors) and multidimensional (several organs affected at the same time); in addition to causing a multitude of injuries in a short period of time, which saturate the health care services; hence it is considered a mass casualty incident. The pathophysiology of blast injuries is the subject of this narrative review.
Methicillin-resistant Staphylococcus aureus (MRSA) bacteremia and challenges to clear it in patients with cardiac devices
Authors: Youssef Dima , Lal Shankar , Baljepally Vinila Shri , Elah Muhammad Abubakar
Published: November 2024

Infections related to cardiac implantable electronic devices present a significant challenge for specialists and often necessitate the removal of these devices. Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most common culprits behind these infections. When MRSA bacteremia occurs in conjunction with a cardiac device infection, imaging studies may not always confirm the involvement of the device. However, it is common practice to remove the entire device to effectively control the source of the infection. Patients may require long courses of antibiotic therapy, and sometimes a combination of two or more antibiotics is necessary to clear the associated bacteremia. Prophylactic treatment for presumptive endocarditis is frequently employed to prevent the infection from spreading to other parts of the body. Recurrence or persistence of MRSA bacteremia often mandates the removal of the cardiac device, raising concerns about the patient's reliance on the device. This manuscript aims to provide a comprehensive overview of the challenges in managing MRSA bacteremia in patients with cardiac devices, highlighting the complexities of diagnosis, treatment options, and the critical decisions surrounding device management.
