«Conjugar una hermenéutica del evangelio y una hermenéutica de las lenguas y culturas»
Authors: Schickendantz Carlos
Published: September 2022

El artículo presenta, primero, una breve revisión de algunos de los textos e interpretaciones más significativos de las décadas recientes sobre el evento conciliar. En segundo lugar, se ofrece una evaluación de conjunto del Vaticano II, particularmente su modus procedendi pastoral caracterizado por la reinterpretación de la gran tradición cristiana que se remonta a Jesús de Nazaret en los nuevos contextos culturales de la humanidad. Esta forma de proceder, expresión de un nuevo paradigma calificado con el término conciliar de pastoralidad, contribuye a la construcción actualizada de identidades creyentes y comunidades eclesiales y al desarrollo de teologías significativas en una lógica dialogal definida por la interculturalidad y la promoción de un escenario eclesial poscolonial que sucede al segundo milenio del cristianismo.

Authors: Yongmei Hou , Dan Wen
Published: September 2022

Objective To explore the characteristic of academic stress and academic burnout, and analyze the impact of academic stress on academic burnout among middle school students in Guangdong Province, China. Methods A stratified cluster sampling method was used to select 1011 students from 6 middle schools in Guangdong province. Academic Stress Scale for Middle School Students (ASSMSS) and Academic Burnout Scale for Middle School Students (ABSMSS) were used to investigate them. Results ⑴ The total scores of ASSMSS and ABSMSS were (60.86±9.31) and (231.43±37.54), respectively. ⑵ The students with rather serious, serious, general, light academic burnout accounted for 13.60%, 20.53%, 24.43% and 41.44%, respectively. The students with serious, general and light academic stress accounted for 66.32%, 3.81% and 29.87%, respectively. ⑶ the result of multivariate stepwise linear regression showed that the scores of competitive stress, task requirement stress, frustration stress and expectation stress were positively correlated with the total score of ABSMSS (β=.258-.459，all P <.001). Conclusions The academic stress and academic burnout of middle school students in Guangdong are rather serious. Academic stress may be an important influenced factor of academic burnout.
Decolonising Museum Practice in a Postcolonial Nation: Museum’s Visual Order as the Work of Representation in Constructing Colonial Memory
Authors: Prianti Desi Dwi , Suyadnya I Wayan
Published: September 2022

The study of colonialism and its legacies have mostly left the category of memory studies. However, for the colonised subject, what they experienced in the past inevitably forms their present and future discourse. This study focuses on how the museum’s visual order articulates colonial memory. By looking at the work of representation, in this context museum’s visual order, this study investigates how memory lives on through the circulation of colonial memory that the museum simulates. Museum’s visual order translates how colonial memory should be remembered and celebrated as public knowledge. Although research on how museums affect society knowledge have been part of both memory and museum studies, those two studies barely touch upon museums’ role in translating colonial memory in the postcolonial nation. Memory lives on through its circulation in media forms. However, premeditation and mediation are made possible through articulating social and cultural sites, in this case, museums practice. In order to achieve its purposes, this research investigates public museums in different parts of Java, Indonesia which have colonial memory objects. The combination of field observation, document review, and visual method followed by focus group discussion between stakeholders and researchers are conducted to propose the research conclusion. This research argues that the museum’s visual order translates interrelated colonial memories to be accepted as a part of the history that forms the “existence” of the nation and to be appreciated as public knowledge that is shared and forms the national identity. In doing so, museum practice roams into the area of political visibility which decides the legibility of the narrative related to colonial memory. In addition, as museum practice is basically a colonial legacy, this research concludes that it is essential to deconstruct the practice from the perspective of the colonised.
An accurate and efficient local one-dimensional method for the 3D acoustic wave equation
Authors: Wu Mengling , Jiang Yunzhi , Ge Yongbin
Published: September 2022

We establish an accurate and efficient scheme with four-order accuracy for solving three-dimensional (3D) acoustic wave equation. First, the local one-dimensional method is used to transfer the 3D wave equation into three one-dimensional wave equations. Then, a new scheme is obtained by the Padé formulas for computation of spatial second derivatives and the correction of the truncation error remainder for discretization of temporal second derivative. It is compact and can be solved directly by the Thomas algorithm. Subsequently, the Fourier analysis method and the Lax equivalence theorem are employed to prove the stability and convergence of the present scheme, which shows that it is conditionally stable and convergent, and the stability condition is superior to that of most existing numerical methods of equivalent order of accuracy in the literature. It allows us to reduce computational cost with relatively large time step lengths. Finally, numerical examples have demonstrated high accuracy, stability, and efficiency of our method.

What do complexity measures measure? Correlating and validating corpus-based measures of morphological complexity
Authors: Çöltekin Çağrı , Rama Taraka
Published: September 2022

We present an analysis of eight measures used for quantifying morphological complexity of natural languages. The measures we study are corpus-based measures of morphological complexity with varying requirements for corpus annotation. We present similarities and differences between these measures visually and through correlation analyses, as well as their relation to the relevant typological variables. Our analysis focuses on whether these ‘measures’ are measures of the same underlying variable, or whether they measure more than one dimension of morphological complexity. Principal component analysis indicates that the first principal component explains 92.62 percent of the variation in eight measures, indicating a strong linear dependence between the complexity measures studied.
Towards a Unity of Theoretical and Practical Reason: On the Constitutive Significance of the Transcendental Dialectic
Authors: König Robert
Published: September 2022

The article focuses on re-evaluating Kant’s Transcendental Dialectic by initially highlighting its seemingly negative function within theCritique of Pure Reasonas a mere regulative form for cognition and experience. The Dialectic, however, does not only have such a negative-regulative function but also its very own positive and founding character for cognition that even is present in the supposedly most immediate forms of intuition. In exploring this positive side of the Transcendental Dialectic it becomes clear that it manifests itself as a bridge between the so-called theoretical and practical reason inasmuch as it fills in their gap within Kant’s philosophy. From the practical side, the Dialectic is manifest as an action full of purposiveness, maxims, and imperatives within cognition, from a theoretical side it assumes the form of syllogistic inference, which is the adequate and acting theoretical form of practical reason. Therefore, the unity of reason is shown in presenting its inner gap as a dialectical misunderstanding that Kant not only highlights in the Transcendental Dialectic but also tends to leave unsolved mostly. Nevertheless, the Dialectic can be shown as thea priorisynthetic act of unifying reason, if investigated in the context of Kant’s complete critical endeavour.
An overview about the approaches used in the production of alpha-ketoglutaric acid with their applications
Authors: Chopra Monika , Kumar Vikas , Singh Manoj , Aggarwal Neeraj K.
Published: September 2022

Alpha ketoglutaric acid is a biological compound found naturally in the human body. It plays an important role in the cell metabolism and has a role in various metabolic pathways including Kreb’s cycle, protein metabolism and so on. Keto glutaric acid is chemically prepared from succinic acid and oxalic acid. It is a direct precursor of glutamic acid and triazines. It can be produced by oxidative decarboxylation of isocitrate by isocitrate dehydrogenase. The yeast Yarrowia lipolytica is used as a prospective producer of alpha ketoglutaric acid from ethanol. The capability to synthesize Keto glutaric acid has so far been investigated for many microorganisms such as Pseudomonas fluoroscens
, Bacillus subtilis
etc. P. fluoroscens have the ability to synthesize a huge amount of alpha ketoglutaric acid in a glycerol medium supplemented with manganese (Mn). The Mangnese has a significant impact on glycerol metabolism resulting in the buildup of alpha ketoglutaric acid. The metabolism of succinate may result in the production of alpha ketoglutarate. Despite its importance in TCA cycle, alpha ketoglutaric acid buildup as an intermediate product of bacterial glucose oxidation. Along with chemical synthesis and microbial fermentation, enzymatic transformation can also be used to produce alpha ketoglutaric acid. Biodiesel waste is considered as cheap and renewable carbon source for the development of alpha ketoglutaric acid. Alpha ketoglutarate is used for kidney disease, intestinal and stomach disorders and many other conditions. It also plays an important role in the food industry as food and nutrient enhancers. The review is covering all the aspects related with the Alpha ketoglutaric acid production, utilization and product recovery.
Embedded-complement and discontinuous pseudogapping in Hybrid Type-Logical Grammar: a rejoinder to Kim and Runner (2022)
Authors: Kubota Yusuke , Levine Robert
Published: September 2022

In their recent paper on pseudogapping in Construction Grammar/HPSG, Kim and Runner (Kim, Jong-Bok & Jeffrey T. Runner. 2022. Pseudogapping in English: A direct interpretation approach.The Linguistic Review.https://doi.org/10.1515/tlr-2022-2094) suggest that the analysis of pseudogapping in Hybrid Type-Logical Grammar (Hybrid TLG) presented in Kubota and Levine (Kubota, Yusuke & Robert Levine. 2017. Pseudogapping as pseudo-VP ellipsis.Linguistic Inquiry48(2). 213–257) does not explain certain complex patterns of pseudogapping for which their own proposal does offer an account. Though Kim and Runner’s (2022) remarks on Kubota and Levine (Kubota, Yusuke & Robert Levine. 2017. Pseudogapping as pseudo-VP ellipsis.Linguistic Inquiry48(2). 213–257) leave room for interpretation, we take it to be reasonably clear that they simply mean that it is difficult to see how such data could be formally accounted for in Kubota and Levine’s proposal. The primary goal of our response is to refute Kim and Runner’s claim on this interpretation. After refuting their claim on this interpretation, we consider a different interpretation of their remarks, one which merely questions the conceptual plausibility of Kubota and Levine’s (2017) broader theoretical architecture. This latter discussion leads to some interesting and important cross-theoretical comparison of different approaches to ellipsis.
Insecticidal activities of the essential oil of Rhynchanthus beesianus rhizomes and its constituents against two species of grain storage insects
Authors: Pan Xiujuan , Xiao He , Hu Xinping , Liu Zhi Long
Published: September 2022

The aim of this research was to evaluate insecticidal activities of the essential oil of Rhynchanthus beesianus rhizomes against adults of Liposcelis entomophila and Tribolium castaneum. Gas chromatography-mass spectrometry analyses revealed the presence of 44 compounds with β-eudesmol (19.1%), elemol (8.1%), α-terpineol (8.0%), methyl eugenol (6.5%), and caryophyllene (4.8%) being the major constituents. Bioactivity-directed chromatographic separation of the oil led to the isolation of four constituents, elemol, β-eudesmol, methyl eugenol, and α-terpineol. The essential oil exhibited fumigant toxicity against the adults of L. entomophila and T. castaneum with LC50 values of 0.57 and 4.96 mg/L air while the two isolates, methyl eugenol and α-terpineol possessed fumigant toxicity against the booklice (LC50 = 0.15 and 0.48 mg/L air, respectively) and the beetles (LC50 = 1.81 and 4.96 mg/L air, respectively). The oil also possessed contact toxicity against the booklice and the beetles with LD50 values of 121.56 μg/cm2 and 54.93 μg/adult, respectively, while the two isolates β-eudesmol and elemol showed contact toxicity against L. entomophila (LD50 = 99.21 and 35.19 μg/cm2, respectively) and T. castaneum (LD50 = 35.26 and 8.89 μg/adult, respectively). The results indicate that the oil of R. beesianus rhizomes and its isolates have potential as a source for natural insecticides.
Reifegradmodelle der ökologischen Nachhaltigkeit
Authors: Korne Thomas , Köhler Christian , Ewald Philipp , Freyler Doreen
Published: September 2022

Reifegradmodelle helfen bei der Leistungsbeurteilung von Organisationen und Prozessen und haben sich insbesondere durch die digitale Transformation in der Fertigungstechnik etabliert. Neuere Reifegradmodelle im Bereich der ökologischen Nachhaltigkeit unterstützen Unternehmen bei der Transformation einer ressourceneffizienten und klimaneutralen Wertschöpfung, vernachlässigen jedoch häufig die speziellen Herausforderungen und Potenziale von kleinen und mittelständischen Unternehmen (KMU). Der Beitrag zeigt Schwächen bestehender Reifegradmodelle der ökologischen Transformation für KMU und damit verbundene Forschungsfragen auf. Hierfür werden Kriterien für KMU insbesondere unter wirtschaftlichen Gesichtspunkten herausgearbeitet und mit 20 Bewertungs- und Reifegradmodellen einer Literaturrecherche abgeglichen. Zur Gestaltung zukünftiger Modelle bieten die Ergebnisse die Möglichkeit, den Nutzen für KMU deutlich zu erhöhen.

Porque importa saber de cerâmica portuguesa no colonialismo atlântico?
Authors: Manuel Casimiro Tânia
Published: September 2022

A presença de cerâmica portuguesa nos territórios atlânticos há muito que tem sido notada. Faiança, cerâmica comum e cerâmica vidrada eram enviadas para as colónias portuguesas do Atlântico, utilizadas nas actividades domésticas e industriais, numa tentativa, muitas vezes não conseguida, de manutenção do estilo de vida europeu e de extrema importância económica para a subsistência das olarias portuguesas. Este artigo planeia ser uma introdução ao enorme potencial de pesquisa que é a análise das evidências cerâmicas portuguesas espalhadas pelo Atlântico.
Narrativas insulares en la arqueología del colonialismo moderno español y portugués
Authors: Ximena Senatore Maria , P. A. Funari Pedro
Published: September 2022

Las perspectivas críticas sobre el colonialismo moderno español y portugués han contribuido a repensar sus tiempos, identidades y contextos, cuestionando las nociones de cambio y los acercamientos esencialistas que tradicionalmente dominaban el campo. Sin embargo, el estudio del colonialismo se ha centrado geográficamente a los espacios bajo dominación colonial lo que ha limitado el pensamiento crítico sobre sus legados en nuestras sociedades actuales. En este trabajo buscamos contribuir a las perspectivas críticas analizando las relaciones entre narrativas que desconectan el mundo europeo del mundo colonial, y la práctica de la arqueología histórica y post-medieval en Iberoamérica y en la Península Ibérica. Esto abre la posibilidad de discutir la utilidad de aplicar herramientas y conceptos vinculados al colonialismo moderno más allá de Latinoamérica.
“Política da consideração” e o significado das coisas
Authors: Sallum Marianne , Silva Noelli Francisco , Carlos Moreno de Sousa João
Published: September 2022

As comunidades agroflorestais sempre formaram os lugares mais numerosos no Brasil, até o presente. As suas relações sociais foram pautadas pela “política da consideração” e economia de colaboração, diferentemente do sistema patriarcal e mercantil europeu. As mulheres tinham proeminência nas comunidades e práticas autossustentadas, segurança alimentar, produção de materialidade e transmissão de conhecimentos. Em São Paulo, a partir de 1502 houve um contexto específico de colonialismo, onde as comunidades Tupiniquim transformaram as relações com parte dos portugueses em relações de aliança, parentesco e consideração, amansando-os e criando materialidades, a exemplo da Cerâmica Paulista. Os portugueses não dominaram as comunidades Tupiniquim, mas uma parte deles ingressou nas comunidades de práticas indígenas, formando posteriormente o “autonomismo paulista”. Nesse contexto, coexistiram práticas colaborativas e de mercado, incorporando pessoas, coisas e conhecimentos de diversos lugares, como um modo de vida diferente daquele desenvolvido nos núcleos urbanos e nas plantations. É preciso compreender que as comunidades tiveram diferentes processos históricos que permitiram as suas persistências até o presente. Há o caso das mulheres que continuam produzindo a Cerâmica Paulista, mas não se consideram indígenas; enquanto outras comunidades, como as Tupi Guarani de Piaçaguera (São Paulo), reivindicam abertamente a identidade “misturada” entre Tupi e Guarani e manifestam o interesse em retomar a produção cerâmica que deixaram de fazer no passado. É um exemplo que exige a reavaliação do apagamento acadêmico dos povos indígenas na historiografia, arqueologia e antropologia em São Paulo, pois eles estão presentes independentemente das narrativas que as pessoas de fora têm produzido a seu respeito.
Colonialismo na arqueologia histórica
Authors: W. Silliman Stephen , Biggie Christian , Cardoso de Mello Louise
Published: September 2022

Este artigo aborda o papel fundacional do colonialismo na arqueologia histórica. Seus objetivos são traçar os caminhos pelos quais o colonialismo tem estruturado as pesquisas e terminologias, tratar sobre as formas como tem sido abordado e negligenciado pela(o)s arqueóloga(o)s históricos, bem como refletir sobre a variedade de conceitos utilizados nesses estudos: contato cultural, colonialismo, pós-colonialismo, resistência, hibridismo, emaranhamento, persistência, sobrevivência e etnogênese. Nesse sentido, o presente trabalho não só avalia os avanços analíticos e as limitações teóricas com respeito ao principal problema de pesquisa da arqueologia histórica do colonialismo – os povos indígenas –, mas também identifica diversas lacunas no que diz respeito às conexões mais que necessárias com a Diáspora Africana e os próprios colonizadores.

SOCIAL RESPONSIBILITY IN THE STRATEGY OF BUSINESS ENTITIES
Authors: Fuchsová Eva
Published: September 2022

Social responsibility is a common part of corporate practice and an established topic of scientific research. Foreign studies have repeatedly concluded that the consistent integration of social responsibility into corporate strategy and strategic management of all dimensions of CSR strengthen corporate growth, bring competitive advantages, and contribute to the sustainable development of society. The aim of the paper is to find out whether even in the Czech Republic business entities with a strategic concept of CSR achieve better economic results compared to those whose approach to social responsibility is rather intuitive and unsystematic. Also, it seeks to answer the question of whether, with different corporate strategies, it is desirable to focus on different CSR activities that would support corporate growth. A survey of the dimensions of strategic CSR and basic economic characteristics was carried out on a set of more than 400 Czech companies engaged in CSR. Data were processed by methods of cluster analysis, factor analysis and multinomial logistic regression. The results show that there is a link between a more advanced (i.e., strategic) concept of CSR and achieving economic prosperity. It was also found that companies with different corporate strategies should carefully consider the benefits of individual CSR activities. All three strategies have shown positive effects resulting from activities aimed at employees and the local community. The differentiation strategy has shown the benefits of cultivating a market environment and the highest quality strategy for human rights protection. On the other hand, with the lowest price strategy, additional CSR activity does not mean an economic advantage. The conclusions contribute to the clarification of the links between strategic CSR and corporate growth in the Czech business environment and contribute specific knowledge that can be implemented by companies if they want to strengthen the positive effects of their socially responsible activities.
EVALUATION OF THE FINANCIAL HEALTH OF FOOD RETAIL OUTLETS IN A MARKET ENVIRONMENT. A CASE STUDY FROM THE SLOVAK REPUBLIC
Authors: Hudáková Stašová Lenka
Published: September 2022

In this paper, food retail stores are evaluated. The aim of the survey is analysis of their financial health using appropriate statistical methods, to analyse the market position of businesses, to identify weaknesses in businesses that may contribute to a poor financial situation, to compare the results obtained and to submit proposals to improve the current financial health of businesses. The analysed sample is made up of a selection of 50 Slovak businesses. The companies operate in the same economic and political system, with similar monetary, customs, tax policy from the government. 4 ratio-based financial analysis indicators were selected as representative (return on assets, return on sales, debt ratio, equity ratio). Multicriterial evaluation methods were used to research the position of businesses on the market (the simple unweighted rank method, the fictional point method, the standardized variable method, the scoring method). We showed the correlations of the methods using Spearman’s rank correlation coefficient. We found the highest correlation in values between the scoring method and the distance from the fictional point method. However, in all cases, by statistical calculation, we found that there is a strong statistically proven relationship between all the methods used. The degree of indebtedness of a business significantly affects its financial health and the structure of the finances. The lowest value for the debt ratio in the monitored sample of businesses is 12.5%. In the group of the worst performing companies, the debt ratio climbed far above the recommended values of 50–70%. The extreme value was a debt ratio as high as 106.3%. We consider the proposals we present to be universal, applicable in other countries in the given sector.

Published: September 2022

The Slovak population, like the population in other European countries, is aging. The population in the older age groups is growing by increasing the average age of life. Even in old age, people are still active, they like to actively participate in social and economic activities, and they carry out various hobby activities, which preserve but also increase the quality of their personal lives. Seniors over the age of 50+, referred to as the silver generation, are important consumers of a wide range of services, including the growing retail services. These are the reasons why an increased attention needs to be paid to them. The aim of the paper is to know the shopping behavior of the silver generation in relation to the specificity of the spatial structure of retail facilities. The research was carried out in the Slovak city of Nitra. This West Slovak city is known for its history, university education facilities and currently especially the automotive industry, which has significantly contributed to improving the economic conditions of its inhabitants. The shopping types of senior respondents were obtained by questionnaires and evaluated by a comparative analysis based on a description. The results of the research show that the behavior of the current silver generation is changing in comparison to the previous one. The closest relationship between the seniors’ traditional way of shopping and the traditional mixed retail facilities in the central part of the city has not been confirmed. The statistically closest relationship between the shopping types of seniors was confirmed in the residential districts where the retail facilities consist of large shopping centers, supermarkets and hypermarkets with a concentrated offer. Senior shopping is changing significantly and is in line with modern trends. New forms of retail supply change the usual patterns of senior shopping behavior.
APPLICATION OF AGILE MANAGEMENT APPROACHES IN SELECTED AUTOMOTIVE COMPANIES IN LIBEREC AND CENTRAL BOHEMIAN REGIONS
Authors: Revutska Olga , Antlová Klára
Published: September 2022

Dramatic changes caused by the rapid spread of the COVID-19 pandemic have emphasized the strategic importance of business agility. Companies around the globe are accelerating their agile transformation to succeed within the contemporary dynamic and complex business environment. This includes both instrumental and cultural changes. It is becoming increasingly clear that agile principles and approaches are no longer exclusively used by IT companies; it is spreading across other business functions and industries. Secondary data analysis confirms a strong ambition of companies towards becoming agile. This paper examines the extent, benefits, and concerns of using agile methodologies by selected automotive companies in the Liberec and Central Bohemian regions of the Czech Republic. The in-depth interviews provide a better understanding of the lower agile maturity of the surveyed companies compared to global statistics. None of the surveyed automotive manufacturers assessed their agile maturity at a high level, nor did they consider agile transformation an urgent strategic priority. Research and Development, Program and Project management stood out as the most agile business functions. At the same time, respondents are clearly aware of the need to increase flexibility and the ability to respond quickly to market changes. Some of the surveyed companies have already successfully incorporated Lean, Kanban and Scrum into their operating models, which are the basics of agile. The primary research findings, combined with secondary data analysis, enable recommendations for those pursuing agile transformation. The paper means to stimulate further in-depth research on the agile management approaches in the manufacturing environment.

Published: September 2022

Objective

To explore the relationship between C-peptide secretion and time in range (TIR) in adult patients with type 1 diabetes.

Methods

From December 2018 to December 2020, 76 type 1 diabetes participants were enrolled from the Department of Endocrinology and Metabolism of Peking University People’s Hospital. All participants wore intermittently scanned continuous glucose monitoring (isCGM), and insulin dosage was adjusted according to standardized clinical procedures. Subjects were divided into low C-peptide group (<10 pmol/L) and preserved C-peptide group (10–200 pmol/L) based on fasting serum C-peptide levels. Differences of TIR, metrics related to glucose variability and hypoglycemic events were compared.

Results

A total of 94,846 isCGM values obtained from 39 male and 37 female participants were analyzed. Individuals with preserved C-peptide secretion had shorter diabetes duration (2.0 (0.5, 10.0) vs 10.0 (3.0, 18.3) years, P = 0.002). TIR was higher in the individuals with preserved C-peptide than those with decreased C-peptide (67.1% (54.2, 75.8) vs 45.5% (33.9, 56.1), P < 0.001), and time above range was significantly lower in those with preserved C-peptide (28.0% (15.6, 42.4) vs 49.4% (39.1, 64.2), P < 0.001). Preserved C-peptide was associated with lower glucose variability, as defined by s.d. (3.0 mmol/L (2.6, 3.4) vs 3.8 mmol/L (3.2, 4.3), P < 0.001) and interquartile range (4.3 mmol/L (3.1, 4.8) vs 5.3 mmol/L (4.5, 6.3), P < 0.001). Metrics related to hypoglycemia were not different between the two groups.

Conclusion

Preserved C-peptide secretion was associated with higher TIR and lower glucose variability in Chinese type 1 diabetes adults.
Bamboo-derived magnetic carbonaceous solid acid catalyst for the conversion of corncob into furfural promoted by warm water immersion
Authors: Li Huiling , Wang Yuqi , Zhu Yikui , Xu Xujian , Wu Aimin , Deng Xiaomei
Published: September 2022

In this study, a bamboo-derived magnetic carbonaceous solid acid catalyst (BC@Fe3O4@SO3H) was synthesized by FeCl3 impregnation, which was followed by incomplete carbonization and -SO3H group functionalization. FT-IR, XRD, and TGA results showed that the prepared catalyst contained -SO3H, -COOH, and phenolic -OH groups. It exhibited poor adsorption ability for the dominating sugars released during the catalytic conversion process. The prepared bamboo-derived magnetic carbonaceous solid acid presented high catalytic activity for depolymerization and conversion of corncob hemicellulose. Warm water immersion under 60 °C was able to destroy the complex corncob cell wall structure and accelerated the dissolution of carbohydrates. The highest furfural yield of 54.1 mg/g was obtained from 40 °C water-immersed corncob after reacting at 180 °C for 30 min. Up to 96.1% of the corncob hemicellulosic backbone sugars were depolymerized to monosaccharides and oligosaccharides in the hydrolysates. The prepared catalyst exhibited a simple magnetic recovery process and high stability. This work provides promising strategies for biomass utilization via renewable materials.
Effect of wax and dimethyl silicone oil pretreatment on wood hygroscopicity, chemical components, and dimensional stability
Authors: Qian Jing , He Zhengbin , Li Jinpeng , Wang Zhenyu , Qu Lijie , Yi Songlin
Published: September 2022

Wood is a renewable and environmental friendly material, but its low dimensional stability characteristics limit its applications. In this study, wax mixed with dimethyl silicone oil was used to enhance the dimensional stability under heat treatment. Samples were heated at 120 °C under 3 impregnation conditions (wax, wax + 20% dimethyl silicone oil, and wax + 40% dimethyl silicone oil) for 3 and 6 h respectively. After treatment the effects of combination pretreatment on wood weight gain percentage (WPG), tangential, radial and volume swelling coefficients (TS, RS, VS), distribution of impregnation liquid, and the types of functional groups of African Padauk (Pterocarpus soyauxii) were evaluated. The results showed that impregnation improved the dimensional stability of wood to a certain extent; moreover, the addition of dimethyl silicone oil improved the modification effect. Furthermore, the VS reduced to 0.66 (±0.28)% in the treatment of wax + 20% dimethyl silicone oil for 6 h. The impregnation liquid mainly adhered to the walls of vessels and ray cells. The hydroxyl absorption intensity of the impregnated groups was lower than that of the control group.

Published: September 2022

During the last decade, the Slovak and Croatian furniture industry markets have experienced changes that have made these markets more interesting for domestic and foreign investors. Furniture manufacturers and retailers are still trying to determine the best ways to adjust to customer demands, and understanding the furniture preferences of customers would provide beneficial information to the furniture industry. The purpose of this study, which was conducted in 2016, was to improve the knowledge regarding differences in the preferences of customers for furniture materials, attributes, and styles when purchasing furniture in Slovakia and Croatia. The findings showed that Slovak and Croatian respondents differ in their preferences for furniture materials, as well as the factors that influence their purchasing decisions when buying interior and exterior furniture. Overall, it was found that wood as the furniture material, compared with the surveyed substitutes, was widely preferred among the Croatian and Slovak respondents.

The effects of the tensile elastic properties of fabrics used as cushion covers, foam thicknesses of cushion cores, seat bases as the support of an upholstered wooden furniture seat foundation, and sitting areas of subjects were studied relative to the load-deformation behavior of cushions situated on wooden seat base frames when subjected to human sitting forces. The experimental results indicated that the sitting area of a subject, fabric tensile elastic constant, and foam thickness had significant effects on the cushion stiffness, but the seat base type did not. The sitting area of a subject had the greatest effect on the cushion stiffness constants, followed by the fabric tensile elastic constant and foam thickness. A regression technique was proposed to derive a power equation for the estimation of the cushion stiffness using the parameters investigated in this study.

To obtain a lightweight and high-strength wood sandwich structure, a wooden lattice sandwich cell element was designed in combination with a pyramid-type structure. After inserting glue to prepare the cell unit, the influence of panel thickness and core diameter on the unit cell force was analyzed and compared under the condition of flat pressure. Under the condition of flat pressure, the specific strength of the unit cell was higher than that of the specific strength of the composition material, and the unit cell may be regarded as a structure with high specific strength. Theoretical predictions, simulation analysis, and experimental tests demonstrated that the structure compressive capacity depended on the diameter of the core when the core length was set. The larger the diameter of the core is, the stronger the bearing capacity of the unit cell will be. When the diameter of the core is constant, the longer the core length is, the weaker the bearing capacity of the unit cell will be. The simulation analysis was in agreement with the experimental test results, indicating that the destruction of the structure was mainly caused by the failure of the core.

Long fibers from fast growing hemp (Cannabis sativa L.) were used as a raw material for the production of insulation boards in this preliminary work. Hemp fiber boards with densities that ranged from 300 kg/m3 to 1100 kg/m3 were studied. The boards were pressed as one- or three-layered structures. In the three-layered structure, the core was formed of hemp fibers and the outer layers were manufactured from 1.5-mm thick birch veneers. The basic insulation properties of the boards were tested. The heat transfer coefficient value for the boards without veneers allowed this material to be classified as an insulating material. Although the additional veneer layers significantly impaired the heat transfer coefficient, its value was still lower than that of standard wood-based board materials with a similar density. The produced boards were characterized as having good noise reduction properties. The acoustic insulation factor was higher compared with boards intended to be used as thermal insulation, such as mineral wool or light fiberboards with four times greater thicknesses.

Caragana korshinskii (C.K.) flat stubble residue is an abundant biomass energy source in China. Because branch cutting is closely related to the harvesting of forest biomass, it is practical for forestry production and ecological development to investigate the effects of cutting parameters on the peak cutting force and cutting energy consumption of C.K. branches. In this study, the effect of cutting parameters on the peak cutting force and cutting power consumption of branches was investigated by single-factor and multi-factor tests using an independently developed reciprocating cutting test bench, and an optimization model was established. The interaction term of average cutting speed and tool cutting edge inclination angle significantly affected the peak cutting force, while the interaction term of cutting clearance and wedge angle had a significant effect on the cutting energy consumption. The optimal combination of cutting parameters was an average cutting speed of 0.5 m/s, cutting clearance of 1.4 mm, wedge angle of 25°, and tool cutting edge inclination angle of 20°. With this combination of parameters, the corresponding peak cutting force was 644.38 N, and the cutting energy consumption was 5.90 J, which was less than 5% relative error between each performance index and the theoretical optimized value.

Published: September 2022

This paper proposes a new multi-criteria group decision-making (MCGDM) method utilizing q-rung orthopair fuzzy (qROF) sets, improved power weighted operators and improved power weighted Maclaurin symmetric mean (MSM) operators. The power weighted averaging operator and power weighted Maclaurin symmetric mean (MSM) operator used in the existing MCGDM methods have the drawback of being unable to distinguish the priority order of alternatives in some scenarios, especially when one of the qROF numbers being considered has a non-belongingness grade of 0 or a belongingness grade of 1. To address this limitation of existing MCGDM methods, four operators, namely qROF improved power weighted averaging (qROFIPWA), qROF improved power weighted geometric (qROFIPWG), qROF improved power weighted averaging MSM (qROFIPWAMSM) and qROF improved power weighted geometric MSM (qROFIPWGMSM), are proposed in this paper. These operators mitigate the effects of erroneous assessment of information from some biased decision-makers, making the decision-making process more reliable. Following that, a group decision-making methodology is developed that is capable of generating a reasonable ranking order of alternatives when one of the qROF numbers considered has a non-belongingness grade of 0 or a belongingness grade of 1. To investigate the applicability of the proposed approach, a case study is also presented and a comparison-based investigation is used to demonstrate the superiority of the approach.

Age-related changes in the stiffness characteristics of the left ventricular (LV) myocardium and the possibility of using them to determine a person’s biological age (BA) were investigated. 188 practically healthy people (115 women and 73 men) were examined, divided by age into 5 groups: I - 30-39 years old (n = 25), II - 40-49 years old (n = 40), III - 50-59 years old (n = 38), IV - 60-69 years old (n = 46), V - 70-79 years old (n = 39). All were examined clinically, echocardiography was performed, the biological age of the cardiovascular system (CVS) was calculated according to the Framingham scale. In practically healthy people, with age, the indicators of left ventricular myocardial stiffness and the energy cost of the heart work statistically significantly increase, and residual energy decreases. Excess BA of the examined in relation to their calendar age was detected in 4 (10%, 95% CI 2.6-21.5), 12 (31.6%, 95% CI 17.6-47.6) and 14 (30.4%, 95% CI 17.8- 44.8) persons in age groups 40-49, 50-59 and 60-69 years, respectively, which indicates accelerated aging of the CVS. A direct correlation of moderate strength between biological age and indicators of the energy cost of the work of the heart has been established. It is advisable to use indicators of myocardial stiffness and energy spent on heart contraction as markers of aging to determine BA CVS.

This review presents current views on the features of сhromium and its compounds, their interconversion, reduction of Cr (VI) by microorganisms, as well as the impact of chromium (VI) on the environment and humans. Chromium can have positive and negative effects on health, according to the dose, exposure time, and oxidation state. The most common forms of this metal in biological systems are trivalent Cr(III) and hexavalent Cr(VI). Hexavalent chromium is mobile, highly toxic to humans, and animals and considered a priority environmental pollutant. He is highly soluble and mobile. On the contrary, Cr(III) has relatively low toxicity and mobility and it is one of the micronutrients needed by humans. Сhromium (III) is an essential nutrient required to promote the action of insulin in body tissues so that the body can use sugars, proteins, and fats. Considerable attention is paid to the issues of interconversion of chromium compounds, reduction of Cr (VI) to Cr (III) by microorganisms, as well as physiological features of their action in humans. The present review discusses on the types of chromate reductases found in different bacteria, their mode of action, and potential applications in the bioremediation of hexavalent chromium. Іn the human body chromium (VI) is rapidly reduced to chromium (III) after penetration of biological membranes and in the gastric environment. The reduction of Cr(VI) to Cr(III) results in the formation of reactive intermediates that together with stress oxidative tissue damage and a cascade of cellular events, contribute to the cytotoxicity, genotoxicity, and carcinogenicity of Cr(VI)-containing compounds.
