Resonance of the tympanoperiotic complex of fin whales with implications for their low frequency hearing
Authors: Morris Margaret , Krysl Petr , Hildebrand John , Cranford Ted
Published: October 2023

The tympanoperiotic complex (TPC) bones of the fin whale skull were studied using experimental measurements and simulation modeling to provide insight into the low frequency hearing of these animals. The study focused on measuring the sounds emitted by the left and right TPC bones when the bones were tapped at designated locations. Radiated sound was recorded by eight microphones arranged around the tympanic bulla. A finite element model was also created to simulate the natural mode vibrations of the TPC and ossicular chain, using a 3D mesh generated from a CT scan. The simulations produced mode shapes and frequencies for various Young’s modulus and density values. The recorded sound amplitudes were compared with the normal component of the simulated displacement and it was found that the modes identified in the experiment most closely resembled those found with Young’s modulus for stiff and flexible bone set to 25 and 5 GPa, respectively. The first twelve modes of vibration of the TPC had resonance frequencies between 100Hz and 6kHz. Many vibrational modes focused energy at the sigmoidal process, and therefore the ossicular chain. The resonance frequencies of the left and right TPC were offset, suggesting a mechanism for the animals to have improved hearing at a range of frequencies as well as a mechanism for directionality in their perception of sounds.

Published: October 2023

Introduction

We aimed to investigate ethnic differences in the associations of potentially modifiable risk factors with dementia.

Methods

We used anonymised data from English electronic primary care records for adults aged 65 and older between 1997 and 2018. We used Cox regression to investigate main effects for each risk factor and interaction effects between each risk factor and ethnicity.

Results

We included 865,674 people with 8,479,973 person years of follow up. Hypertension, dyslipidaemia, obesity and diabetes were more common in people from minority ethnic groups than White people. The impact of hypertension, obesity, diabetes, low HDL and sleep disorders on dementia risk was increased in South Asian people compared to White people. The impact of hypertension was greater in Black compared to White people.

Discussion

Dementia prevention efforts should be targeted towards people from minority ethnic groups and tailored to risk factors of particular importance.
Multimodal factor evaluation system for organismal transparency by hyperspectral imaging
Authors: Shito Takumi T. , Oka Kotaro , Hotta Kohji
Published: October 2023

Organismal transparency constitutes a significant concern in whole-body live imaging, yet its underlying structural, genetic, and physiological foundations remain inadequately comprehended. Diverse environmental and physiological factors (multimodal factors) are recognized for their influence on organismal transparency. However, a comprehensive and integrated quantitative evaluation system for biological transparency across a broad spectrum of wavelengths is presently lacking. In this study, we have devised an evaluation system to gauge alterations in organismal transparency induced by multimodal factors, encompassing a wide range of transmittance spanning from 380 to 1000 nm, utilizing hyperspectral microscopy. Through experimentation, we have scrutinized the impact of three environmental variables (temperature, salinity, and pH) and the effect of 11 drugs treatment containing inhibitors targeting physiological processes in the ascidian Ascidiella aspersa. This particular species, known for its exceptionally transparent eggs and embryos, serves as an ideal model. We calculated bio-transparency defined as the mean transmittance ratio of visible light within the range of 400–760 nm. Our findings reveal a positive correlation between bio-transparency and temperature, while an inverse relationship is observed with salinity levels. Notably, reduced pH levels and exposure to six drugs have led to significant decreasing in bio-transparency (ranging from 4.2% to 58.6%). Principal component analysis (PCA) on the measured transmittance data classified these factors into distinct groups. This suggest diverse pathways through which opacification occurs across different spectrum regions. The outcome of our quantitative analysis of bio-transparency holds potential applicability to diverse living organisms on multiple scales. This analytical framework also contributes to a holistic comprehension of the mechanisms underlying biological transparency, which is susceptible to many environmental and physiological modalities.
The association between the amino acid transporter LAT1, tumor immunometabolic and proliferative features and menopausal status in breast cancer
Authors: Ramshankar Gautham , Liu Ryan , Perry Rachel J.
Published: October 2023

L-type Amino Acid Transporter 1 (LAT1) facilitates the uptake of specific essential amino acids, and due to this quality, it has been correlated to worse patient outcomes in various cancer types. However, the relationship between LAT1 and various clinical factors, including menopausal status, in mediating LAT1’s prognostic effects remains incompletely understood. This is particularly true in the unique subset of tumors that are both obesity-associated and responsive to immunotherapy, including breast cancer. To close this gap, we employed 6 sets of transcriptomic data using the Kaplan-Meier model in the Xena Functional Genomics Explorer, demonstrating that higher LAT1 expression diminishes breast cancer patients’ survival probability. Additionally, we analyzed 3′-Deoxy-3′-18F-Fluorothymidine positron emission tomography-computed tomography (18F-FLT PET-CT) images found on The Cancer Imaging Archive (TCIA). After separating all patients based on menopausal status, we correlated the measured 18F-FLT uptake with various clinical parameters quantifying body composition, tumor proliferation, and immune cell infiltration. By analyzing a wealth of deidentified, open-access data, the current study investigates the impact of LAT1 expression on breast cancer prognosis, along with the menopausal status-dependent associations between tumor proliferation, immunometabolism, and systemic metabolism.

Published: October 2023

The South-to-North Water Diversion East Project (SNWDP-E) is an effective way to realize the optimal allocation of water resources in China. The North Dasha River (NDR) is the reverse recharge section that receives water from the Yufu River to the Wohushan Reservoir transfer project line in the SNWDP. However, the dissolved organic matter (DOM) evolution mechanism of seasonal water transfer projects on tributary waters has not been fully elucidated. In this paper, the NDR is the main object, and the changes in the composition and distribution of spectral characteristics during the winter water transfer period (WT) as well as during the summer non-water transfer period (NWT) are investigated by parallel factor analysis (PARAFAC). The results showed that the water connectivity caused by water transfer reduces the environmental heterogeneity of waters in the basin, as evidenced by the ammonia nitrogen (NH4+-N) and total phosphorus (TP) in the water body were significantly lower (p<0.05, p<0.01) during the water transfer period than the non-water transfer period. In addition, the fluorescence intensity of DOM was significantly lower in the WT than the NWT (p<0.05) and was mainly composed of humic substances generated from endogenous sources with high stability. While the NWT was disturbed by anthropogenic activities leading to significant differences in DOM composition in different functional areas. Based on the redundancy analysis (RDA) and multiple regression analysis, it was found that the evolution of the protein-like components is dominated by chemical oxygen demand (COD) and NH4+-N factors during the WT. While the NWT is mainly dominated by total nitrogen (TN) and TP factors for the evolution of the humic-like components. This study helps to elucidate the impact of water transfer projects on the trunk basin and contribute to the regulation and management of inter-basin water transfer projects.
Seasonal shifts in pronghorn antelope (Antilocapra americana) diets under a new lens: Examining diet composition using a molecular technique

Published: October 2023

Foraging is one of the most fundamental activities contributing to the maximization of an animal’s fitness, and thus herbivores must optimize their diet selection and intake to meet their nutrient demands for survival, growth, and reproduction. Using plant DNA barcoding, we determined diet composition of five subpopulations of adult female pronghorn antelope (Antilocapra americana) grazing rangelands in southern and southeastern Idaho, USA. Fecal samples were collected for two years (2018–2019), and across metabolically-important adult female life history stages (late gestation, early lactation, breeding season). Plant DNA barcoding yielded 137 detected species within pronghorn diets across subpopulations and sampling periods with forbs being the most abundant. Pronghorn dietary functional group composition ranged from 52.2–60.3% from forbs followed by shrubs (22.6–28.2%), graminoids (8.7–15.7%), and legumes (5.5–9.6%). Dietary protein intake was also highest from forbs and ranged from 32.4–62.4% followed by graminoids (1.2–43.1%), shrubs (18.7–21.3%), and legumes (2.6–7.4%). We found significant intra- and interannual differences in the mean number of genera-based plant detections in pronghorn diets. Dietary protein intake of cultivated legumes (e.g., alfalfa [Medicago sativa] and sainfoin [Onobrychis viciifolia]) was lower than expected, ranging from <1.0–30.8%, suggesting that even within an agricultural-dominated landscape, factors other than plant nutritional composition contributed to pronghorn diets. Although the plant DNA barcoding technique exhibits limitations, it demonstrated potential for elucidating pronghorn dietary species richness, particularly for plants consumed in small proportions, as well as for observing temporal fluctuations in functional group composition and dietary protein intake explained through the interplay between environmental factors, plant chemical composition, and the animals’ physiological needs.

Published: October 2023

Aelia fieberi Scott, 1874 is a pest of crops. The mitogenome of A. fieberi (OL631608) was decoded by next-generation sequencing. The mitogenome, with 41.89% A, 31.70% T, 15.44% C and 10.97% G, is 15,471 bp in size. The phylogenetic tree showed that Asopinae and Phyllocephalinae were monophyletic; however, Pentatominae and Podopinae were not monophyletic, suggesting that the phylogenetic relationships of Pentatomoidae are complex and need revaluation and revision. Phytophagous bugs had a ~20-nucleotide longer in nad2 than predatory bugs. There were differences in amino acid sequence at six sites between phytophagous bugs and predatory bugs. The codon usage analysis indicated that frequently used codons used either A or T at the third position of the codon. The analysis of amino acid usage showed that leucine, isoleucine, serine, methionine, and phenylalanine were the most abundant in 53 species of Pentatomoidae. Thirteen protein-coding genes were evolving under purifying selection, cox1, and atp8 had the strongest and weakest purifying selection stress, respectively. Phytophagous bugs and predatory bugs had different evolutionary rates for eight genes. The mitogenomic information of A. fieberi could fill the knowledge gap for this important crop pest. The differences between phytophagous bugs and predatory bugs deepen our understanding of the effect of feeding habit on mitogenome.

Published: October 2023

Rationale

Methamphetamine use and related harms have risen at alarming rates. While several psychosocial and pharmacologic interventions have been described in the literature, there is uncertainty regarding the best approach for the management of methamphetamine use disorder (MUD) and problematic methamphetamine use (PMU). We conducted a scoping review of recent systematic reviews (SR), clinical practice guidelines (CPG), and primary controlled studies of psychosocial and pharmacologic treatments for MUD/PMU.

Methods

Guided by an a priori protocol, electronic database search updates (e.g., MEDLINE, Embase) were performed in February 2022. Screening was performed following a two-stage process, leveraging artificial intelligence to increase efficiency of title and abstract screening. Studies involving individuals who use methamphetamine, including key subgroups (e.g. those with mental health comorbidities; adolescents/youths; gay, bisexual, and other men who have sex with men) were sought. We examined evidence related to methamphetamine use, relapse, use of other substances, risk behaviors, mental health, harms, and retention. Figures, tables and descriptive synthesis were used to present findings from the identified literature.

Results

We identified 2 SRs, one CPG, and 54 primary studies reported in 69 publications that met our eligibility criteria. Amongst SRs, one concluded that psychostimulants had no effect on methamphetamine abstinence or treatment retention while the other reported no effect of topiramate on cravings. The CPG strongly recommended psychosocial interventions as well as self-help and family support groups for post-acute management of methamphetamine-related disorders. Amongst primary studies, many interventions were assessed by only single studies; contingency management was the therapy most commonly associated with evidence of potential effectiveness, while bupropion and modafinil were analogously the most common pharmacologic interventions. Nearly all interventions showed signs of potential benefit on at least one methamphetamine-related outcome measure.

Discussion

This scoping review provides an overview of available interventions for the treatment of MUD/PMU. As most interventions were reported by a single study, the effectiveness of available interventions remains uncertain. Primary studies with longer durations of treatment and follow-up, larger sample sizes, and of special populations are required for conclusive recommendations of best approaches for the treatment of MUD/PMU.
Dissection of key factors correlating with H5N1 avian influenza virus driven inflammatory lung injury of chicken identified by single-cell analysis
Authors: Dai Manman , Zhu Sufang , An Zhihao , You Bowen , Li Ziwei , Yao Yongxiu , Nair Venugopal , Liao Ming
Published: October 2023

Chicken lung is an important target organ of avian influenza virus (AIV) infection, and different pathogenic virus strains lead to opposite prognosis. Using a single-cell RNA sequencing (scRNA-seq) assay, we systematically and sequentially analyzed the transcriptome of 16 cell types (19 clusters) in the lung tissue of chickens infected with H5N1 highly pathogenic avian influenza virus (HPAIV) and H9N2 low pathogenic avian influenza virus (LPAIV), respectively. Notably, we developed a valuable catalog of marker genes for these cell types. Compared to H9N2 AIV infection, H5N1 AIV infection induced extensive virus replication and the immune reaction across most cell types simultaneously. More importantly, we propose that infiltrating inflammatory macrophages (clusters 0, 1, and 14) with massive viral replication, pro-inflammatory cytokines (IFN-β, IL1β, IL6 and IL8), and emerging interaction of various cell populations through CCL4, CCL19 and CXCL13, potentially contributed to the H5N1 AIV driven inflammatory lung injury. Our data revealed complex but distinct immune response landscapes in the lung tissue of chickens after H5N1 and H9N2 AIV infection, and deciphered the potential mechanisms underlying AIV-driven inflammatory reactions in chicken. Furthermore, this article provides a rich database for the molecular basis of different cell-type responses to AIV infection.

Published: October 2023

En el año 2020 se realizaron a nivel mundial 45.652 fusiones y adquisiciones entre organizaciones, una cada 12 minutos. A pesar de la magnitud de esta cifra, la experiencia demuestra que se trata de un proceso complejo y arriesgado que presenta un elevado porcentaje de fracasos y que está, entre otras cuestiones, influido por el sector al que pertenecen las organizaciones. Esta investigación persigue tres objetivos: (1) estimar el número de entidades que se han fusionado en el subsector de las discapacidades intelectuales y del desarrollo en España desde el año 2000 a 2020; (2) caracterizar dichas fusiones; y (3) aportar recomendaciones para mejorar las probabilidades de éxito en los procesos de fusión. Para ello, se ha realizado un estudio de carácter cuantitativo y alcance descriptivo para determinar el número de entidades que se han fusionado, combinado con otro de carácter cualitativo y comprensivo para conocer cómo han sido los procesos de fusión. La investigación ha revelado que en este periodo se han llevado a cabo 5 fusiones en las cuales han participado 20 entidades y se puede afirmar, a juzgar por la valoración de las personas que las han liderado, que han sido exitosas, aunque no exentas de dificultades.
The role of information in shaping sustainable human behaviour
Authors: Streimikiene Dalia , Mikalauskiene Asta , Macijauskaitė – Daunaraviciene Ugne
Published: October 2023

Encouraging environmentally friendly behaviour in population is one of today's greatest sustainability challenges. Over the last decades, many scientists of environmental psychology, social psychology and behavioural economics studied the dependence of an individual's sustainable behaviour on stratification and various direct and/or indirect factors. External and internal factors determining the individual's behaviour are based on information sources and how, in what way, and at what level the initial data is perceived, as well as how the individual uses such sources. This article conducted in Lithuania aims to find out which information sources an individual is most likely to reach, and what factors would encourage the integration of sustainable natural resource-saving solutions into everyday life.
Innovations and international competitiveness: Country-level evidence
Authors: Tadevosyan Ruzanna
Published: October 2023

The paper studies the interaction between innovations and international competitiveness and the main objective is to determine the potential impact of innovations on competitiveness and assess the extent of that impact. Therefore, the paper questions (a) whether innovations cause competitiveness, and (b) to what extent the innovations influence competitiveness. Based on the literature review, the export of goods and the number of patent applications (both per million people) are taken as proxies and chosen as indicators for measuring innovations and international competitiveness. Cross-country panel data analysis is performed for a sample of 67 countries over the period of 1993-2020. The selection of countries was based on the availability of data on all variables. The autoregressive model whose dependent variable is the export of goods and the independent variables are the number of patent applications, foreign direct investments, and the real effective exchange rate is estimated using the Random effect model. The results show that patents have a positive impact on export, though its extent is not so significant. The Granger causality test also confirms that patents cause increased export. The research results hold practical value for policymakers.

Research activities play a critical role in facilitating growth and promoting sustainable development. However, the scientific interest level in the European Green Deal in Central Asia remains uncertain. Therefore, this research paper aims to define the interest of Central Asian researchers in the Green Deal. A literature review was conducted using the bibliographic analysis method for Web of Science publications published over 2018-2023 and originating from Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan. Co-occurrence analysis of keywords and co-authorship analysis were performed using the VosViewer 1.6.19 software. The co-occurrence analysis revealed that the Green Deal is a complex and interdisciplinary issue that highlights the importance of collaboration among stakeholders and researchers from different sectors. The co-authorship analysis identified the patterns of collaboration among authors, with many working with international partners. The distribution of publications and citations varied across different countries and keywords related to environmental and sustainability topics. It was also found that the number of publications has been increasing. Finally, correlation and regression analysis were applied to identify the factors that influence publication activity about the Green Deal.
Employment effects of childcare availability: Evidence from European Union
Authors: Szüle Borbála
Published: October 2023

There are several factors that contribute to the success of a society. Economic and demographic developments are known as important drivers, while the role of parental employment as a key component is sometimes overlooked. This paper focuses on the effects of childcare availability on female and male employment in the European Union regions. Regional differences may be significant, therefore separate panel regression models (with economic and demographic control variables) are established for regions in old and new member states, and the results are compared across different levels of male and female educational attainment. The findings suggest that there is a considerable difference between old and new members states. The availability of early childhood educational development significantly increases employment both for female and male employees with higher education levels in new members states, while this effect is not significant in old member states. For male employees with relatively low education levels, the availability of early childhood educational development does have a significant effect on employment both in old and new member states but this does not hold for female employees with lower education levels.

Ambiwalencja jako próba odzyskania autentyzmu w reprezentacji Szoa. Przykład Arnošta Goldflama
Authors: Firlej Agata
Published: October 2023

The starting point for this research is the crisis in discourse and pedagogy related to the representation of the Holocaust, as well as the crisis of empathy in itsperception, signaled by, among others, Ernst van Alphen. With the passage of time increasing numbers of representations appear that push the boundaries ofinappropriateness, requiring new approaches and new scientific findings. The Czech playwright Arnošt Goldflam, a representative of the second generation of survivors and at the same time an artist associated with the independent culture of the 1960s and 1970s, uses the category of ambivalence in his plays about the Holocaust, which may be considered as flirting with inappropriate representations of Shoah, leading to a convincing attempt to overcome its crisis.

Greetings from Spinalonga! O wyspie ciszy w fotografii społecznościowej i o kulturze pamięci na Instagramie
Authors: Nowak Tomasz Łukasz
Published: October 2023

In modern narratives, the island of Spinalonga appears an attractive tourist destination with an interesting and enigmatic history. In fact, Spinalonga is a memory space, encumbered with past political decisions and medical negligence. This is the story of the great confinement, the isolation of the sick who were symbolically killed. Meanwhile, the photos shared on Instagram show theisland in a completely different light.The article seeks to answer the following questions: Does the behavior of Instagram users disrupt the culture of memory and how do these photos (digital representations of memory) influence the image of the island? To this end, I outline the history of the island in the context of exclusion mechanisms for those with Hansen's disease. I discuss the issues of dark tourism, social photoand desemantization of communication. I juxtapose the whole thing with the examples of photos from Spinalonga published on Instagram in 2022.
Effect of varied waste concrete ratios on the mechanical properties of polymer concrete
Authors: Rasheed Aliaa , Sadiq Shatha , Shaaban Aseel
Published: October 2023

Polymer concrete (PC) was developed at the end of the 1950s and gained popularity in the 1970s for precast parts, flimsy floor coverings, and repairs. Due to its superior performance over traditional Portland cement concrete, which offers many benefits, including mechanical properties, quick hardening, and durability. In this article, polymeric concrete was made using a mixture of sand and epoxy, and different proportions of sand were replaced with crushed concrete waste. This study found that the ideal ratio between resin and fine aggregate was 23% resin to 77% fine aggregate in terms of the total weight of the combination to get the best dispersion of fine aggregate. Waste concrete replaced 5, 10, 15, and 20% of aggregate in PC, respectively. It was further demonstrated that increased waste concrete aggregate content in PC increased the 28-day compressive strength by 7.7, 13.44, 16.8, and 18.97%, respectively; flexural strength increased by 16.68, 25.32, 37.16, and 47.71% at 28 days’ age; and direct tensile strength was higher than the reference mixture by values of 3.41, 17.21, 23.54, and 30.38% at 28 days age. The findings recommended using recycled fine aggregate on PC and suggested a 20% replacement ratio as an optimum percentage.
The Contemporary Significance of Early German Romantic Philosophy

Recent interest in early German Romantic philosophy can be linked to other approaches, such as that of John Dewey, which are critical of the dominant direction of modern philosophy. The Romantics rethink the relationship between philosophy and art as a way of questioning modern philosophy’s focus on epistemology and scepticism that leads to a lack of attention to the diverse other ways in which human beings make sense of things.

Published: October 2023

Using case studies from Aşıklı Höyük, Çatalhöyük, Boncuklu Tarla, Göbekli Tepe (all Turkey), and Monjukli Depe (southern Turkmenistan), this study presents a framework for in-depth research on prehistoric earthen architecture in southwestern and central Asia. It demonstrates the challenges and potential for innovative and comparative studies based on interdisciplinary approaches and the use of architectural, microstratigraphic, and microarchaeological analyses. Furthermore, it sheds new light on issues related to various aspects of building continuity which is commonly recognised as a very important phenomenon in the Neolithic but could have different facets. The study attempts to discuss the reasons behind the local decisions to use and recycle specified building materials. In addition, it evaluates – in relation to particular sites – the usefulness of specific analyses for reconstruction of daily, seasonal, or annual practices. Advanced analyses of floors and fire installations, for instance, can contribute not only to the identification of indoor and outdoor surfaces but also to a better understanding of activity areas and the intensity of use within particular spaces. Variations and different combinations of mudbrick, mortar, and plaster recipes allow for insights into how earth and sediment material were used to mark collective and individual identity through the performance of a building. Recognising reused materials and features allows us to trace further the nature of prehistoric societies and local architectural dialects.
Análisis de notas periodísticas sobre violencia contra las mujeres mediante estrategias de gestión de datos desde el diseño de información
Authors: Mata-Santel Jaqueline , Luna-Gijón Gerardo , Ronquillo-Bolaños Abraham
Published: October 2023

El diseño de información es una disciplina que ayuda a visibilizar la violencia hacia las mujeres. En este texto, mediante un acercamiento mixto, se presenta un análisis de notas periodísticas reportadas por tres periódicos digitales sobre la violencia ejercida contra mujeres en Puebla, México, durante el mes de enero de 2022. Los hallazgos nos muestran que los medios referidos no presentan datos suficientes para identificar el perfil del agresor y que se despersonaliza a quien ha sufrido violencia, de manera que el lector no puede dimensionar la situación reportada. Se espera que este trabajo contribuya a la valoración del diseño de información como una herramienta que, mediante procesos de gestión de la información, revela patrones que, de otra manera, permanecerían inadvertidos. Se plantea lo anterior en el entendido de que el hacer visible la información es un primer paso para combatir las desigualdades. Como conclusión, se señala que los periódicos perpetúan patrones que invisibilizan la violencia.
Zooarqueología de todo un valle: cambios en el consumo de animales en los últimos 3.400 años en El Valle de Mauro, Norte Semiárido de Chile (31°s)
Authors: López Mendoza Patricio , Villalón Daniela , Rivera Bárbara
Published: October 2023

Se presentan y discuten los resultados del análisis zooarqueológico de 37 sitios arqueológicos del Valle de Mauro (31º57`S-71º01`O, ~900 msnm), emplazado en la franja meridional del Norte Semiárido del actual territorio chileno. Estos sitios abarcan una secuencia cronológica y cultural que va desde el Arcaico Tardío (ca. 3.400 años cal AP en adelante) hasta ocupaciones históricas, enfatizando la secuencia prehispánica asociada a eventos del Período Alfarero Temprano (El Molle), Intermedio Tardío (Diaguita) y Periodo Tardío (Inca). Nuestros resultados indican un consumo intensivo de camélidos (Lama guanicoe) durante el Arcaico que desciende drásticamente en sincronía con la aparición de la cerámica y prácticas hortícolas en el valle. Hacia momentos Diaguita y con prácticas agrícolas consolidadas junto a la aparición de camélidos domésticos (Lama glama), proponemos la necesidad de repensar a estos grupos con prácticas pastoriles trashumantes condicionadas por los ciclos de pasturas en el Semiárido, tal como se observa para momentos históricos.

Solvent-producing Clostridium acetobutylicum was purified and used in an acetone-butanol-ethanol (ABE) fermentation process. The objective of this study is to design a fermentation medium for the synthesis of butanol and determine the ideal glucose concentration for appropriate microbe ingestion. The fermentation medium was incubated at 37 °C for up to 90 h before inoculation while being sparged with nitrogen gas under anaerobic conditions. Based on the optical density of fermentation media, the growth rate was also monitored. At 60 g/L of glucose, which was the optimum condition for fermentation, the process followed a log phase pattern until the death phase, with the largest growth taking place between 10 h and 50 h after incubation. The C. acetobutylicum steadily consumed the glucose content, reaching its maximal consumption with only around 12 g/L remaining. In contrast to acetone and ethanol, which produced the highest concentrations at 6.4 g/L and 5.2 g/L, respectively, butanol productions were seen appropriately, with the greatest concentration yielding 11.2 g/L of butanol. This shows that C. acetobutylicum expressed its active metabolism for up to 60 g/L and further increase of glucose content will deteriorate the performance of butanol production.
Atomic layer deposited TiO2 on a foam-formed cellulose fibre network – Effect on hydrophobicity and physical properties
Authors: Keskiväli Laura , Seppänen Tiinamari , Porri Paavo , Pääkkönen Elina , Ketoja Jukka A.
Published: October 2023

Climate change and plastic pollution challenge us to develop alternatives for fossil-based plastics, and cellulose-based materials are excellent candidates for this. Foam forming technology for cellulose fibre products increases process efficiency, widens the raw materials base, and enables low-density structures from fibres. Low-density cellulose-based materials can be used, for example, for packaging, insulation, and construction materials. However, to achieve optimal performance, the resistance against moisture and mechanical compression ought to be enhanced. In this research, the effect of atomic layer deposited (ALD) titanium dioxide on four foam-formed cellulose-based structures was studied. The hydrophobicity of these materials was analyzed with water contact angle measurements. Moisture content and mechanical properties were tested at high humidity (50% RH and 90% RH) by analyzing moisture uptake and compression strength. Furthermore, the morphology and microstructures were evaluated with scanning and transmission electron microscopy (SEM and TEM). ALD treatment changed the hydrophilic materials to hydrophobic with 5 cycles of TiO2 for all four substrates. The effect on moisture content was milder but was observed strongest with unrefined and partly refined samples at 50% RH. A clear trend between moisture content and mechanical strength was detected since the compression strength increased with decreasing moisture content.

In this study, different from the definition of Dubois and Prade (1990), the fuzzy rough set is defined within the framework of the rough group concept defined by Biswas and Nanda (1994), and some of its algebraic properties are discussed. Then, the concepts of fuzzy rough subgroup and fuzzy rough normal subgroup are introduced in the rough group. In addition, some basic features and examples of these concepts are given.

Authors: Ramírez-Pérez Mauricio , Lee-Maturana Saulyn
Published: October 2023

This systematic literature review aimed to explore, identify and synthesise the relationship between trade unions and employees’ well-being. The academic databases Web of Sciences, PsychInfo, Scopus and SciELO were systematically searched from their inception until August 2022. The systematic review followed the, PRISMA-P protocol, and was registered in PROSPERO (ID= CRD42022374339). Eighteen articles were the results of the systematic search. Nevertheless, none of them met the inclusion criteria. An interesting twist occurred when the excluded articles were analyzed, given that it was possible to show the topics of interest in which scholars publish in this area.
A Randomized Controlled Clinical Trial Evaluating the Performance of Bis-GMA Free Resin Composite Posterior Restorations
Authors: Reda Sara Ahmed , Hussein Yasser Fathi , Riad Mona
Published: October 2023

Objective: This study aims to assess the clinical performance of Bis-GMA free resin composites (RCs) in comparison with Bis-GMA based resin composites as posterior restorations during 1,3,6,9, and 12 months, using a split-mouth, double-blinded randomized design. Methods and Materials: The study included 20 participants who received a pair of class I or II bulk-fill composite restorations. One side of the mouth was filled with Bis-GMA free RC (Admira Fusion x-tra), while the other side received Bis-GMA based RC (X-tra fil). Restoration placement was done by a single operator following the manufacturer's guidelines and was finished and polished immediately following placement. Modified United States Public Health Services (USPHS) criteria have been adopted for restoration assessment at baseline (1 week), 1, 3, 6, 9, and 12 months. The statistical analysis was accomplished utilizing Wilcoxon tests, with a 0.05 significance level. Results: After 12 months, all patients attended the recall visits with a 100% recall rate. The Wilcoxon signed rank tests revealed insignificant differences between both groups (p?0.05) for all USPHS parameters. The two studied materials showed a decline from 100% clinically excellent scores, with a few recordings of clinically good scores at 12 months. However, most restorations maintained clinical Alpha and Bravo score throughout the 12-month period. Conclusions: The Bis-GMA-free RCs' clinical performance was comparable to that of Bis-GMA-based RCs in posterior permanent teeth restorations after 12 months. These findings suggest that Bis-GMA-free RCs can be considered a viable alternative to Bis-GMA-based RCs in clinical practice.
Inventario sobre el estudio de la interpretación musical de estudiantes universitarios de música y conservatorios
Authors: Panizo Pimentel Fernando José
Published: October 2023

Interpretar música como actividad formativa, artística y como aprendizaje tanto técnico – práctico, teórico, analítico formal e histórico musicológico profesional, resulta una tarea compleja que va más allá de la mera intuición que en la actualidad se tiene de los músicos. El presente articulo busca reunir información sobre los aspectos principales que conforman el estudio de la interpretación musical a nivel universitario o de conservatorios con la finalidad de determinar su definición y descripción teórica, su aplicación en los procesos artísticos como también en los procesos de enseñanza – aprendizaje de jóvenes intérpretes dedicados a la profesionalización de la música. En tal sentido, interpretar música, desde un marco académico, remite el aspecto histórico (concepto tratado desde mediados del siglo XX) cuyo enfoque pasa por la búsqueda de la fidelidad y el uso de diversas herramientas investigativas a fin de acercarse a la idea de cómo quiso el compositor que su obra suene cuando se creó. Comprende, además aspectos de análisis gramatical, de contextos culturales y filosóficos, de aporte personal al momento de ejecutar una obra musical, el de la expresividad que pasa por estudios multi dimensionales como el modelo GERMS, y la formación y evaluación como aspecto académico universitario y de conservatorios.
La gestión en TIC y el desempeño docente en instituciones educativas estatales de las ciudades de Lima y Callao
Authors: Gamboa Dios Rosa Luz
Published: October 2023

Este trabajo pretende establecer si la gestión en TIC se vincula con el desempeño docente en instituciones educativas estatales de Lima y Callao en el año 2017. Se empleó un diseño descriptivo correlacional, soportado por la regresión lineal simple de Pearson. Para esto se elaboraron y validaron dos instrumentos de medición: una encuesta y una ficha de recolección de datos. A partir de la población, se hizo el cálculo de la muestra con error máximo admisible de 6 %, por lo que se evaluó de manera aleatoria a 169 instituciones educativas de Lima y Callao. Luego del recojo y el análisis estadístico, se determinó que las variables presentan correlación lineal; es decir, una buena gestión en TIC influye directamente en el desempeño docente. Así, queda demostrado que se cumple la hipótesis general, la cual sostiene que la relación entre ambas variables es directa y altamente significativa. Finalmente, se presenta una propuesta de un proyecto apropiado para la correcta gestión de las TIC y el desempeño docente: el COBIT 5.

La pandemia ocasionada por el COVID -19 provocó transformaciones intempestivas en cómo estaban organizadas distintas sociedades, siendo salud y educación los sectores que más sufrieron alteraciones en su funcionalidad práctica. El Perú en el ámbito de su educación universitaria representa un caso llamativo para medir los impactos del confinamiento y sus consecuencias, pues la alta exigencia en la preparación, los tiempos determinados, los nuevos medios de interacción educativa, sus falencias e improvisación representaron una sobrecarga de actividades que bien pudiera haberse traducido en estrés. Siendo así, nuestro objetivo al revisar bibliografía vinculada es analizar y determinar el nivel de estrés académico que se presenta en estudiantes de universidades públicas en nuestro país. Los resultados indican que los niveles de estrés en estos estudiantes han alcanzado porcentajes altos y moderados, debido a las sobre exigencias académicas resultantes del contexto de confinamiento. Frente a ello ¿Qué hacer? Esta podría ser solo la primera pandemia del presente siglo, no la última.

Análisis de la normatividad vigente que rige el funcionamiento y la organización curricular para la formación educativa de los estudiantes de los CEBA
Authors: Flores Luna Martha Ofelia
Published: October 2023

En el presente trabajo se analizó la normatividad vigente que rige el funcionamiento y la organización curricular para la formación educativa de los estudiantes de los Centros de Educación Básica Alternativa (CEBA) habiéndose detectado que la organización curricular y funcionamiento del Ciclo Avanzado de Educación Básica Alternativa no coadyuva en el logro de las competencias, en la formación integral de los estudiantes, ni en la calidad educativa; asimismo que la gestión pedagógica del Ciclo Avanzado de los CEBA no enfatiza la preparación laboral, siendo que el área de Educación para el Trabajo se desarrolla por lo general en teoría, no en la práctica, dado que los CEBA no cuentan con aulas de innovación pedagógica; o de ser el caso, con talleres de electricidad, corte y confección, cosmetología, ebanistería, plomería, carpintería, gasfitería, etc., por lo que no se cumple lo dispuesto por el artículo 37 de la Ley General de Educación N°. 28044. Por otro lado, se ha determinado que los CEBA no otorgan diploma de egresado con mención en un área técnica de acuerdo con el artículo 35° de la citada ley y tampoco da atención a niños y adolescentes menores de 14 años.

Authors: González Liens Betsy , Olivera Rodríguez Víctor Luis
Published: October 2023

El trabajo que se presenta a continuación tiene como objetivo describir la metodología y aspectos colaterales respecto al voleibol y la enseñanza en secundaria básica, dirigido fundamentalmente al diseño de juegos predeportivos para la familiarización de los estudiantes con las habilidades motrices en dicho deporte; estos juegos servirán como herramienta importante no solo en las clases de educación física propiamente dichas, sino también para emplearlos en las comunidades donde viven los estudiantes, dándoles la oportunidad de utilizar el tiempo libre en actividades saludables que les permitan un desarrollo espiritual, biológico, psicológico y social adecuado. La metodología empleada incluyó niveles teóricos sustentados en el método analítico-sintético y a nivel empírico, se empleó la observación. Se tomó como referencia el grupo 8vo 1 de la ESBU 30 “Aniversario de la Batalla de Guisa”, del municipio de Bayamo, en la provincia de Granma, Cuba. Las conclusiones revelan la forma en la que mediante estos juegos se pretende elevar la cultura deportiva de los estudiantes dentro y fuera del centro de estudio.
