Effects Of Locally-Made Probiotics on Drinking Water on the Performance of Chickens
Authors: Moniño Analyn Cinco , Ibañez Jr. Roger Yatan , Moniño Jr. Primitivo Diaz
Published: September 2023

This study investigated the effects of locally-made probiotics on the performance of Kabir and Starbro broilers. The birds were randomly assigned to four treatments, and their body weight, weight development, feed consumption, feed conversion efficiency, dressing percentage, livability rates, and income over feed and chick cost were measured. The results showed a significant interaction between the breed of chicken and the type of probiotics after 21 days of feeding in terms of body weight, body weight gain, feed consumption, and feed conversion efficiency. However, no significant interaction was observed at 35 days of feeding. The use of locally produced probiotics in drinking water improved the dressing percentage of both breeds of chicken, overall body weight gain, and overall feed consumption compared to the control group. Livability rates were not significantly affected by the inclusion of different locally-made probiotics in drinking water. Net income per chicken was marginally higher for the chickens fed with locally produced probiotics. Further studies are recommended to assess the benefits of locally-produced probiotics in laying chicken and other types of livestock and poultry. These findings provide insights into the potential application of locally-made probiotics as an alternative to commercial products for improving chicken performance.

Published: September 2023

The Mekongga local language of Indonesia is an essential part of this country's cultural variety. Unfortunately, the number of speakers of the local Mekongga languages is decreasing. The Mekongga local language, like other local languages in Indonesia, is on the verge of extinction due to a declining number of speakers. Therefore, preserving the Mekongga local language is critical in order to preserve local wisdom and the local community's cultural identity. This research aims to describe the maintenance function of the Mekongga local language in the Wundulako Sub-district, Kolaka Regency, Southeast Sulawesi. The quantitative descriptive approach was used in this research, with research subjects consisting of adolescents and adults who were native speakers of the Mekongga language. The data was collected using a closed questionnaire and analyzed using a percentage descriptive technique. The research's findings show that the speaking community's attitude toward maintaining the Mekongga local language is positive, with an average of 76.23. However, there are still concerns about the potential extinction of the Mekongga local languages, especially amid the increasing challenges of globalization and modernization. Therefore, more optimal and concrete efforts are needed to preserve the local Mekongga language. These findings provide important implications for development policies directed at maintaining the Mekongga local language and local wisdom inherited from the past. This implication can positively contribute to the development of culture in Indonesia as a whole. This research can also significantly contribute to further research related to maintaining local languages and local wisdom in Indonesia.
Resenha: SOUZA, Ricardo Timm. Crítica da razão idolátrica
Authors: Branco Judikael Castelo
Published: September 2023

Crítica da razão idolátrica, de Ricardo Timm de Souza, representa, acima de tudo, um esforço para compreender um “mundo doente”. No entanto, é importante ressaltar que não se trata meramente de mais um exercício de diagnóstico desse mundo, ou seja, não é apenas uma nova abordagem dos inúmeros problemas que o cercam, embora essa tarefa seja sempre relevante. Na obra em questão, a crítica vai além da análise de um mundo enfermo e das suas condições; ela também aponta para o “estado de suspensão” característico da crítica filosófica contemporânea, diante de um universo repleto de ideias, imagens e ações que transformaram o mundo atual em um “imenso e infernal maquinismo de conversão incessante de qualidades e singularidades em quantidades e generalidades”.
From atomistic to collective dynamics: Bridging gaps in gas-phase electron microscopy for catalysis
Authors: Hansen Thomas Willum , Willinger Marc
Published: September 2023

Catalysis is a highly complex phenomenon involving fundamental processes on multiple length scales. The full-scale complexity of catalysis is only poorly understood, and how atomic-scale processes influence long-range order in the materials is not well documented experimentally. The result is that we still, to a large degree, develop new catalysts on the basis of iterative trial-and-error approaches. Elucidating the link between atomic-scale structural dynamics, feedback mechanisms, and collective behavior could be the key to a deeper understanding and further optimization of catalysts and processes. From imaging of quasi-static low-energy configurations through gas-phase-induced state switching to observation of complex nonequilibrium dynamics and oscillatory behavior, electron microscopy has provided novel insights over several length and time scales and has meanwhile matured from a service tool for catalyst researchers to a driving force in catalysis research. Here, we discuss new insights provided by novel instrumentation and the extension fromin situtooperandoinvestigations, enabling the study of mechanisms and kinetics of catalytic processes.

POR UMA POÉTICA CURRICULAR COM OS COTIDIANOS ESCOLARES
Authors: Delmondes Marina de Oliveira , Ferraço Carlos Eduardo
Published: September 2023

Trata-se do resultado da pesquisa de doutorado desenvolvida durante o contexto da pandemia da Covid-19 e do necrogoverno instaurado no Brasil entre 2018 e 2022. Com o objetivo de problematizar os múltiplos currículos vividos-praticados-inventados com os cotidianos escolares, apostou-se na metodologia da pesquisa com os cotidianos e na epistemologia pós-estruturalista, fazendo uso da filosofia da diferença de Deleuze e Guattari como aporte conceitual. Ao considerar os cotidianos escolares como espaços-tempos de tessitura curricular e de políticas inventivas, apostou-se na escrita como dispositivo vital que reverberou em múltiplas escrevinhações-curriculantes. O ato de escrever com os praticantes dos cotidianos escolares aquilo que lhes afetava desencadeou, para além de um método de produção de dados, um movimento curricular de experimentação da vida em um tempo de distanciamento social, assim, também, foi um modo de encontros (DELEUZE; PARNET, 1998). Por fim, ao defender uma poética curricular como da ordem dos afetos e, portanto, capaz de instaurar um outro devir, um outro estilo, uma outra criação, um outro modo de pensar-inventar currículos, faz-se uma defesa das escolas públicas como compromisso ético, estético e político desta pesquisa em educação.
DA MODERNIDADE DESENCANTADA AOS REENCANTAMENTOS POSSÍVEIS
Authors: Oliveira Inês Barbosa de
Published: September 2023

Pensar o reencantamento do mundo e a relevância das criações curriculares cotidianas nesse processo exige recorrermos ao fenômeno e ao processo de desencantamento do mundo de modo a poder tecer uma reflexão que aborde diferentes aspectos do debate, inserindo-os no debate curricular. Assim sendo, este artigo recorre ao pensamento weberiano sobre o desencantamento produzido na e pela racionalidade moderna e ao diálogo deste com algumas das formulações de possibilidades do reencantamento. Por meio de extensa pesquisa bibliográfica, percorrem-se as diferentes contribuições para a reflexão sobre este, de Morin e Prigogine com a compreensão do reencantamento pela renovação da ciência, a Krenak e Gudynas, que preconizam uma nova relação com a natureza, e a Maffesoli e sua compreensão da renovação das sociabilidades e recurso às tecnologias como reencantamentos em curso. Importante ressaltar a contribuição de Boaventura de Sousa Santos, tanto pela relação que estabelece entre o reencantamento do mundo e a vida cotidiana – fundamental para pensar as criações curriculares – quanto por sua abordagem mais ampla, que dialoga com todas as já referidas, e com o campo do currículo.  Em sua parte final, com base nas diferentes contribuições elencadas, o texto examina brevemente algumas criações curriculares narradas em trabalhos acadêmicos no campo da pesquisa com os cotidianos das escolas, nas quais se podem encontrar contribuições à reflexão sobre o tema, bem como iniciativas relevantes de contribuição possível das escolas e daquilo que nelas se cria para o reencantamento do mundo.

O artigo risca os caminhos a partir dos saberes assentados nas práticas afro-brasileiras e indígenas com a orientação do professor ancestral Pai Joaquim da Calunga, um Preto Velho que baixa em um Terreiro de Umbanda localizado na zona norte do Rio de Janeiro. Rodopiando nos moldes civilizatórios de uma cultura hegemônica, cruzando possibilidades outras de ser e estar no mundo, incitando a própria potência criativa de estudantes, com a Banda e a Quimbanda, misturando corpos plurais que circulam nos espaços escolares e que muitas vezes incutem a ideia de serem fadados a determinados fins negativos nas periferias, é que vamos fazer a gira girar. Na lógica de uma Educação como experiência de liberdade do ser e de acúmulo e troca de força vital, como axé, a responsabilidade é firmar ponto em um pedaço de cipó curricular e desatar os nós da violência colonial, exercitando a fluidez dos diversos caminhos possíveis. Portanto, esse artigo parte de uma ideia de que nem sempre é possível evitar a morte do corpo físico, mas é possível reencantar o mundo através da potência de vida.
LITERATURA MARGINAL-PERIFÉRICA E FORMAÇÃO
Authors: Matos Nayara , Baroni Patricia Raquel , Coelho Gustavo
Published: September 2023

Esta pesquisa tem o objetivo de investigar a potência formativa da produção literária marginal-periférica a partir das narrativas de escritores periféricos. Assumindo que esta pesquisa não poderia estar dissociada da minha trajetória de vida, a narrativa (auto)biográfica perpassa toda a pesquisa como instrumento importante no processo de investigação e (auto)formação (SOUZA, 2007). A partir do entendimento de que a literatura marginal-periférica é sempre singular e local, mas ao mesmo tempo global e social, a abordagem metodológica partirá também da pesquisa narrativa (CLANDININ e CONNELLY, 2011) e da metodologia de conversas (SAMPAIO; RIBEIRO; SOUZA, 2018). Com a produção de Soares (2009) e de Ferréz (2005), das minhas vivências como escritora periférica e das narrativas de outros escritores periféricos, busco compreender como a literatura marginal-periférica se inscreve em diferentes espaços de formação, dentre eles, as ruas e as escolas. Deste modo, a pesquisa visa contribuir para a ampliação das discussões sobre os aspectos formativos da literatura marginal-periférica no campo da educação.
Energy trade relations between Russia and China
Authors:   Jagiellonian University in Cracow, Yamato Sayaka
Published: September 2023

Economic relations between Russia and China have been growing over the years. Of particular importance in Russia-China economic relations is the gas and oil trade. Russia has the world’s largest natural resources, while China is the world’s largest energy consumer. In 2014, an agreement was reached to build a new gas pipeline and increase gas exports to China. If the planned volume of gas can be exported to China on a stable basis, Russia will be able to supplement some of the economic sanctions imposed by the West. However, there is much uncertainty as to whether China can be a stable export destination for Russia. There is a significant gap in the trade scale between Russia and China and asymmetrical dependence in the relationship between them. In addition, international pipeline projects have substantial financial and time costs, and the two countries; intentions sometimes differ. The purpose of this research is to clarify the current state of trade interdependence between Russia and China and to study whether China can be a stable economic partner for Russia. This paper consists of three main parts, with an introduction and conclusions. The first part explains an overview of trade and asymmetric interdependence between Russia and China. It then analyses the anticipated benefits and vulnerabilities of increased Russian gas exports to China. The third section investigates the uncertainties of China as a gas importer in terms of China’s dependence on Russia.

Authors: Kstenin Vitaly , Volkov Andrey
Published: September 2023

Within the framework of this article, the authors consider the company JSC "VkusVill" from the standpoint of the reliability and integrity of its suppliers. As part of a large range of products, the authors focus on the bakery industry, since this type of product is in the greatest demand and is basic for any food retailer. To apply the due diligence method, the authors selected two suppliers: PJSC "Ruzsky Khlebozavod" (RH) and PJSC "Sotsinnovation" (SI). This article compares the two organizations. The authors have developed checklists for checking contractors for reliability. The most important aspects of retail are considered in detail: legal, tax, financial and marketing. Comparisons are presented in the form of tables, each of which is explained. In addition, the authors analyzed the levels of legal, financial, tax risks of counterparties to determine the most trustworthy counterparty. Also, within the framework of this article, the authors provide a formula with which you can calculate the assessment of the effectiveness of counterparties of VkusVill JSC. After that, the authors give a calculation of the costs of improving the method of checking counterparties and the damage to JSC "VkusVill" from the disruption of the supply of bakery products. Based on the results obtained, a general indicator of economic efficiency was calculated and a conclusion was made about the economic activity of the company JSC "VkusVill". Since the due diligence system of counterparties ensures the most efficient functioning of the company, VkusVill JSC needs to improve this mechanism and pay more attention to it. To achieve this goal, a list of references was selected to form the most complete picture of the object and subject under study.

The dry stacking of filtered tailings has emerged as an alternative way of dealing with the safety-related problems of conventional slurry disposal in reservoirs behind upstream dams. Incorporating a cementing agent into the tailings before compaction can enhance the overall geomechanical behaviour of these structures, giving rise to more stable and safer stackings. However, few dry stacks are in operation worldwide and their field performance needs to be better understood. In addition, the addition of cement provides further challenges to the design of these structures. Obtaining reliable laboratory data for properly designing these tailings storage facilities is thus essential. Accordingly, the mechanical behaviour of artificially cemented iron ore tailings for dry stacking purposes was evaluated, with a focus on comparing the responses between field-compacted samples and laboratory-assembled specimens. To do this, ultrasonic pulse velocity, unconfined compression, split tensile and triaxial compression tests were carried out. Both the stiffness and strength data were well described by the porosity/cement index and, despite minor differences, good agreement was found between the responses of the laboratory-assembled and field-compacted samples. The findings highlight the adequacy of laboratory procedures for reflecting the material's real-field conditions.
Study on the performance of micro-arc oxidation coatings on TA10 titanium alloy with graphite additions
Authors: Chen Xiaowen , Tang Song , Wu Chen , Xie Wanlin , Zhang Meng , Zhang Defen
Published: September 2023

To improve the corrosion resistance of the Ti–0.3Mo–0.8Ni (TA10) titanium alloy, a micro-arc oxidation coating was prepared on its surface, and the effect of different amounts of graphite addition on the structure and corrosion resistance of the coatings was studied. Through methods such as X-ray diffraction phase analysis, microscopic morphology analysis, roughness analysis, coating thickness analysis and hardness testing, it was found that the added graphite particles can react with silicon (Si) in the electrolyte to promote the formation of the silicon carbide (SiC) phase, thereby improving the surface morphology of the coatings, increasing the thickness of the coatings and improving the microhardness of the coatings. At the same time, dynamic potential polarization curve and scanning electrochemical test results show that the formation of the silicon carbide phase can increase self-corrosion potential and reduce self-corrosion current density. When the amount of graphite added is 1.0 g/l, the self-corrosion potential and self-corrosion current density are −0.129 V and 2.9 × 10−8 A/cm2, respectively. This indicates that adding graphite particles can enhance the corrosion resistance of the TA10 titanium alloy.
GENDER DIFFERENCES IN PERCEPTIONS TOWARDS THE USE OF FORCE
Authors: SAYAN Pınar
Published: September 2023

The existence of gender differences in public attitudes has long been debated and it is maintained that women and men have different attitudes towards certain policy areas. One of those areas is the use of force in foreign policy. Women are less supportive of the use of force in foreign policy than men. The reasons for these differences have been tried to be explained through the impact of the factors such as partisanship or ideology; economic marginalization; political marginalization; negative responses to war casualties; feminist consciousness; motherhood; socialization; issue salience. While public opinion surveys have been regularly conducted on foreign policy in Turkey, the gender dimension is rather understudied. In this article, I first argue that there are gender differences in public perceptions towards the use of force in Turkey and I aim to explore the reasons for these differences based on two sets of focus group discussions data gathered in 2021 and 2022.

Published: September 2023

Arrogant behaviors negatively affect relations and communication within the organization. The primary purpose of the research is to determine the effects of colleague arrogance on collaboration, organizational gossip, and emotional exhaustion. Quantitative research method was adopted. Within the scope of the research, a questionnaire form was prepared on an online platform and applied between 16 January-10 February 2023. The questionnaire was sent to the academicians via e-mail, and 391 academicians participated. Looking at the results of the regression analysis, the perception of colleague arrogance has a negative and significant effect on the collaboration of academicians. The perception of colleague arrogance positively and significantly affects the emotional exhaustion of academicians. When we look at another finding, colleague arrogance positively and significantly affects negative work gossip. At the same time, the perception of colleague arrogance does not have a significant effect on positive work gossip. In conclusion, we think this research has brought a different and vital perspective to the perception of colleague arrogance. In organizational arrogance research, the importance of investigating the emotions and behaviors that occur in individuals has been put forward first.
Schistosoma mansoni cercariae transformation (with needle) v1
Authors: K Buddenborg Sarah
Published: September 2023

Free-living aquatic S. mansoni cercariae transform into the first intramammalian stage,called schistosomula or somules, by burrowing in the host skin. Upon contact, cercariae begin to enter the skin and lose their tails, becoming schistosomula. Somules migrate through the epidermis to the dermis to find a small venule or lymphatic vessel to enter the vasculature. Transformation of cercariae to schistosomula can be mimicked in the laboratory by triturating cercariae to remove tails, eliminating tails in a percoll gradient, and then culturing the somules in somule media. This method is used when the number of cercariae is high as the percoll gradient results in loss of cercariae. Somules can be cultured for several weeks with regular media changes.
RFE-Based Feature Selection to Improve Classification Accuracy for Morphometric Analysis of Craniodental Characters of House Rats

Published: September 2023

In conventional morphometrics, researchers often collect and analyze data using large numbers of morphometric features to study the shape variation among biological organisms. Feature selection is a fundamental tool in machine learning which is used to remove irrelevant and redundant features. Recursive feature elimination (RFE) is a popular feature selection technique that reduces data dimensionality and helps in selecting the subset of attributes based on predictor importance ranking. In this study, we perform RFE on the craniodental measurements of the Rattus rattus data to select the best feature subset for both males and females. We also performed a comparative study based on three machine learning algorithms such as Naïve Bayes, Random Forest, and Artificial Neural Network by using all features and the RFE-selected features to classify the R. rattus sample based on the age groups. Artificial Neural Network has shown to provide the best accuracy among these three predictive classification models.
Peta Ketumpatan Fizikal bagi Menentukan Unsur Berisiko Banjir di Kawasan Kota Belud, Sabah, Malaysia
Authors: Sharir Kamilia , Roslee Rodeano
Published: September 2023

Banjir merupakan bencana alam yang berlaku setiap tahun dan memberi impak kepada kehidupan manusia, gangguan sosio-ekonomi dan kemusnahan alam sekitar. Terdapat tiga komponen penting dalam mentafsir risiko banjir iaitu; Bahaya, Kemudahterancaman dan Pendedahan. Pendedahan dalam konteks ini merujuk kepada unsur yang terdedah atau berisiko kepada sesuatu kerugian dan mempunyai tahap kemudahterancamannya yang tersendiri. Rekod kejadian banjir di kawasan ini semakin meningkat terutamanya selepas kejadian Gempa Bumi Ranau 2015. Peningkatan kejadian ini menjejaskan kelangsungan hidup kerana kebergantungan komuniti setempat terhadap hasil pertanian seperti penanaman padi untuk menjana pendapatan selain penempatan kemudahan fasiliti awam seperti hospital, pejabat kerajaan dan sekolah. Justeru, mengenal pasti unsur berisiko di kawasan ini amatlah penting untuk meminimumkan risiko banjir yang akan menjejaskan kawasan ini. Objektif utama kajian ini adalah untuk mengenal pasti unsur berisiko yang terdedah kepada ancaman bencana banjir di kawasan Kota Belud, Sabah. Pendedahan unsur berisiko boleh dikenal pasti secara nyata atau tidak nyata. Unsur berisiko nyata dikenal pasti melalui jejak bangunan dan jenis jaringan jalan raya yang ada di sekitar kawasan kajian manakala unsur berisiko tidak nyata pula, analisis ini dilakukan secara soal selidik di lapangan. Peta Ketumpatan Fizikal (PKF) kemudian dihasilkan daripada jejak bangunan dan peta jaringan jalan raya untuk menggambarkan unsur berisiko pada skala rantau. Peta ini dihasilkan dengan menukar poligon bangunan menjadi titik dan pengiraan dibuat berdasarkan kilometer persegi dan menggabungkannya dengan maklumat ketumpatan jaringan jalan raya. Kaedah ini turut digunakan sebagai kaedah alternatif untuk menggambarkan taburan penduduk bagi kawasan yang mempunyai ketersediaan dan kebolehcapaian data yang terhad. Hasil analisis menunjukkan kawasan unsur berisiko yang berketumpatan fizikal tinggi terletak berhampiran dengan sungai-sungai utama seperti Sungai Kadamaian, Sungai Wariu, Sungai Gurong-gurong, Sungai Tempasuk dan Sungai Abai. Kajian ini amat berguna sebagai kajian perintis dalam mentafsir risiko banjir di kawasan ini dan berpotensi dikembangkan di kawasan lain agar kerosakan dan kerugian harta benda, infrastruktur atau utiliti awam dapat diurus dan dikurangkan.
Seed Germination Characteristics as Affected by Interaction of Moisture Stress and Temperature in Sethoxydim-Resistant Biotype of Goosegrass (Eleusine indica (L.) Gaertn.) from Malaysia

Published: September 2023

Understanding temperature and moisture stress that influence sethoxydim-resistant (R) goosegrass (Eleusine indica) germination is crucial for effective weed control, but little research has been done on the impact of these environmental factors on germination of the R goosegrass biotype. This research aims to confirm sethoxydim resistance in goosegrass and to examine interaction effects of different temperatures and water potentials on germination of the R goosegrass biotype. Dose–response tests showed that the R goosegrass biotype exhibited high resistance level to sethoxydim with 17-fold. In laboratory bioassays, the R goosegrass biotype germinated by 88-100% at 35 °C with water potentials ranging from 0 to -0.80 MPa, but no seed germination occurred at 10 °C and 40 °C under all water potential treatments. With rising water potentials from 0 to -0.80 MPa, seed germination at 15 to 30 °C decreased markedly. The time it took to achieve 50% seed germination (T 50) increased drastically when decreasing temperature from 35 to 15 °C. The T50 at 20 to 30 °C also increased as the water potential increased from -0.20 to -0.80 MPa. At 35 °C, however, the water potential level had no impact on T 50, implying that the R goosegrass biotype seed is water stress tolerant at 35 °C. The base temperature and base water potentials estimated were 10.6 °C and -1.28 MPa, respectively. These findings can help in determining the optimal time to apply pre-emergent and early post-emergent controls when a large proportion of R goosegrass biotype have already germinated or emerged.
Sound-Absorbing Material Based Oil Palm Frond Natural Fibres
Authors: Ewe Lay Sheng , Yew Weng Kean , Woon Hai Song , Ibrahim Zawawi
Published: September 2023

Effective noise control is vital for improving living standards, but traditional sound absorbers pose health risks. Natural fibers offer a sustainable alternative, with consistent absorption rates across a broad frequency range. These fibers, widely available in Malaysia, are non-toxic, lightweight, renewable, and eco-friendly, making them an attractive option. The safety benefits of natural fibers further enhance their appeal as sound absorbers, making them an excellent choice for those concerned about environmental impact and personal health. This study will examine the effect of different thicknesses on the acoustic performance of natural fibers from oil palm fronds (OPF). The findings demonstrate that, when material density is 160 kg/m3, all thicknesses can achieve a good Sound Absorption Coefficient (SAC) of 0.8 or greater within 3600 - 6400 Hz range. However, at 180 kg/m3 density, only the 10 mm thickness sample has SAC of 0.8 or greater, but for 2800 - 6400 Hz range. It is worth noting that, across 0 - 6400 Hz, 10 mm thick and 180 kg/m3 density sample has higher SAC than 160 kg/m3 samples. Nevertheless, for 12 mm, 14 mm, and 16 mm thicknesses, SAC of 160 kg/m3 is higher than 180 kg/m3 after an interception point. Before that interception point, SAC of 160 kg/m3 is lower than 180 kg/m3. As thickness increases from 12 mm to 16 mm, the interception point decreases from 2100 Hz to 1600 Hz. The research demonstrates that various factors, such as frequency, density, thickness, and fiber structure, impact the acoustic performance of OPF LDF.
Mechanical Characteristics of Developed Brick from Drinking Water Sludge Under Different Firing Temperatures and Rice Husk Ash Contents
Authors: Ali Rahman Zulfahmi , Nazarah Hafis , Idris Wan Mohd Razi , Lihan Tukimat
Published: September 2023

There is a considerable interest in making alternative bricks using wastes. Firing temperature has been significantly improved the mechanical qualities of bricks. The aim of this study was to investigate into the impact of firing temperature and rice husk ash content on the mechanical properties of drinking water sludge bricks (DWS). Two types of bricks were produced; bricks made of 100% DWS (DWS100) and bricks with 80% DWS and 20% RHA (DWS80). These samples were subjected to different thermal variations of 300 °C and 700 °C for three hours. The unfired brick samples were also prepared for reference. The volume changes of the DWS100 bricks increased as the firing temperature climbed up to 500 °C, before dropped at 700 °C. A similar behaviour was also exhibited by DWS80 bricks, however it shrunk at earlier temperature of 500 °C. At 500 °C and 700 °C, the density of bricks decreased dramatically, with DWS80 bricks consistently being lesser than DWS100 bricks. The water absorption of DWS80 brick began to decrease at 500 °C, a lower temperature than that of DWS100, as the firing temperature climbed. RHA-added bricks (DWS80) were anticipated to absorb more water than DWS100 bricks, but this did not occur. This presumably induced by the constriction of clay mineral structure rather than organic matter removal at high temperature per se. The compressive strength increased with the increase in temperature. It can be inferred that RHA can decrease the compressive strength of RHA-added bricks, despite the fact that a higher fire temperature significantly increased their strength.
Downplaying Euroscepticism in Mainstream Media: The Schengen Accession of Romania and Bulgaria
Authors: Ștefănel Adriana , Momoc Antonio , Surugiu Romina
Published: September 2023

Scholars have expressed concern about the growth of Eurosceptic discourses in the media since Taggart’s (1998) article on Euroscepticism. While some progress has been made in understanding the media’s role in increasing Euroscepticism, previous studies have primarily focused on Western European media discourses. This research aims to address the knowledge gap on Eurosceptic discourse in Eastern Europe by analysing the impact of the veto against Romania and Bulgaria’s application to join Schengen, as reflected in mainstream media. The research question is: To what extent the Eurosceptic discourse arose in both countries in the weeks before and after the Justice and Home Affairs Council (8–9 December 2022)? The findings indicate that mainstream-mediated discourse employed a strategy of downplaying Euroscepticism. The Romanian and Bulgarian political class labelled the failure to join Schengen as “disappointing,” “unfair,” “unjustified,” and “regrettable.” This research provides evidence of how mainstream media discourses addressed the issue while promoting the European integration project by minimising Euroscepticism.
Constructing the “Good Citizen”: Discourses of Social Inclusion in Swedish Civic Orientation
Authors: Bauer Simon , Milani Tommaso M. , Von Brömssen Kerstin , Spehar Andrea
Published: September 2023

Sweden has long been described as a beacon of multiculturalism and generous access to citizenship, with integration policies that seek to offer free and equal access to the welfare state. In this article, we use the policy of Civic Orientation for Newly Arrived Migrants as a case with which to understand how migrants’ inclusion is discursively articulated and constructed by the different constituencies involved in interpreting the policy and organising and teaching the course. We do this by employing Foucault’s closely interrelated concepts of technology of self, political technology of individuals, and governmentality. With the help of critical discourse analysis, we illustrate how migrants’ inclusion is framed around an opposition between an idealised “good citizen” and a “target population” (Schneider & Ingram, 1993). In our analysis, we draw on individual interviews with 14 people involved in organising civic orientation and on classroom observations of six civic orientation courses. Firstly, we show how migrants are constructed as unknowing and in need of being fostered by the state. Secondly, we illustrate how social inclusion is presented as being dependent upon labour market participation, both in terms of finding work and in terms of behaving correctly in the workplace. Lastly, we show how migrant women are constructed as being problematically chained to the home and therefore needing to subject themselves to a specific political technology of self to be included.
Migrants’ Inclusion in Civil Societies: The Case of Language Cafés in Sweden
Authors: Majlesi Ali Reza , Jansson Gunilla , Kunitz Silvia
Published: September 2023

This article investigates the role of language cafés as venues where newly arrived migrants to Sweden can socialize and practice the target language. More specifically, we aim to explore how café organizers and volunteers orient to social inclusion as they are interviewed about the goals of the local café and engage in talk‐in‐interaction with the visitors during video‐recorded café sessions. At the methodological level, we rely on ethnomethodologically informed ethnography and conversation analysis, through which we adopt an emic approach to data analysis by taking into account the members’ interpretation of their social world and the actions they accomplish in it. Our analysis uncovers the organizers’ and volunteers’ conceptualization of social inclusion, which they articulate in terms of fostering a sense of belonging and empowerment; they also perceive the mutual benefits derived from the encounters with the migrants at the local café. Overall, the migrants’ views dovetail with the concept of “everyday citizenship,” which highlights the dimensions of belonging, rights, and access to resources for social participation as constitutive of social inclusion. These findings highlight the perceived role of language cafés as a way to act on the existing social reality to transform the local community into an inclusive, equal, and integrated society.
Mental health and psychiatry: Distinctions, links, and ethical/bioethical perspectives
Authors: Perales Alberto , D. Alarcón Renato , Wagner-Grau Patrick
Published: September 2023

Introduction. Mental health and psychiatry have been terms of intense and complex use for almost a century, and they may have reached a critical level of ambiguous and imprecise synonymy that makes their definition and validation difficult. Objective. To examine these concepts in depth, establishing precise distinctions, ontological connections, and instrumental scope reinforced by well-defined ideas in ethics and bioethics. Method. Narrative review of pertinent literature, consultation with diverse scientific, medical, historical, philosophical, and literary sources, with appropriate analysis of ethical and bioethical practices. Results. A broad, comprehensive definition is elaborated of mental health as a field with sociocultural, political, and demographic implications, and of psychiatry as a medical specialty. In addition to making clear distinctions and describing the specific impact of both fields on diverse populations, various levels of conceptual linkages, sociopolitical action, and ethical content are highlighted, as well as in processes of administration, education, and research. Discussion and conclusion. There are factors that reinforce or weaken the scope of mental health and psychiatry, including their ethical and bioethical dimensions. Their effectiveness requires a reaffirmation of objectives and the reinforcement of individual and institutional initiatives, as well as the search for authentic connections and a social projection that is objective, comprehensive, and just.

Myocarditis is often difficult to diagnose. The diagnostic difficulties include nonspecific symptoms or a “vague” clinical picture, absence of pathognomonic signs during physical examination, and endomyocardial biopsy, which is the “gold standard” of diagnosis of myocarditis, being an invasive procedure that is performed under strict indications in certain patients. Nevertheless, as radiology is rapidly developing, clinicians are now able to noninvasively diagnose symptoms of inflammatory myocardial damage, including edema and myocardial fibrosis, using cardiac magnetic resonance imaging. This article presents the clinical case of a young patient with symptoms of acute coronary syndrome, who showed no evidence of coronary artery disease. Myocarditis was suspected because of increased activity of cardiospecific enzymes and high levels of inflammatory markers, pronounced electrocardiography changes with positive dynamics, and recent infection. Magnetic resonance imaging was used to confirm myocarditis diagnosis. Thus, this case study demonstrates the role of imaging techniques in the differential diagnosis of ischemic and inflammatory heart diseases.

BACKGROUND: Primary progressive aphasia is a rare neurodegenerative disease with high clinical, genetic, and pathomorphological heterogeneity that greatly complicates its diagnosis. Voxel-based morphometry can be used to objectively assess structural gray matter changes and determine atrophy patterns in variants of primary progressive aphasia, which can improve the diagnosis and our understanding of its pathogenesis.
AIMS: This study aimed to evaluate the patterns of atrophy in each of the primary progressive aphasia variants in comparison with the control group.
MATERIALS AND METHODS: Patients diagnosed with one of the primary progressive aphasia variants, established in accordance with the current diagnostic criteria, were included in the main group. The control group consisted of healthy volunteers without any neurological symptoms or structural brain changes. All participants underwent brain magnetic resonance imaging. The obtained images were processed and used for voxel-based morphometry, which was performed by comparing the gray matter volume between each of the primary progressive aphasia variants and the control group. The study was adjusted for the sex, age, and intracranial volume of the participants.
RESULTS: The study enrolled 25 patients with nonfluent, 11 with semantic, and 9 with logopenic variants of primary progressive aphasia, as well as 20 healthy volunteers. Voxel-based morphometry showed a specific atrophy pattern in each of the variants of primary progressive aphasia, with predominant involvement of the frontal and insular lobes in nonfluent, temporal lobe and hippocampus in semantic, and a more diffuse frontotemporal pattern in logopenic variants.
CONCLUSIONS: The study revealed gray matter atrophy patterns specific to each variant of primary progressive aphasia. The obtained results mainly correspond to the clinical presentations of the disease. Moreover, some findings (e.g., absence of the posterior perisylvian atrophy and reduced motor cortex volume in the logopenic variant, atrophy of the orbitofrontal cortex and cerebellum in the nonfluent variant, and premotor cortex, precentral, and inferior frontal gyrus degeneration in the semantic variant) do not correlate with the usual understanding of primary progressive aphasia pathogenesis and require further study.

Uremic pruritus is a common symptom in chronic kidney disease and end-stage renal failure. In addition to physical discomfort uremic pruritus disrupts sleep, negatively affects the psycho-emotional state and quality of life. In this group of patients, the association of uremic pruritus with an increase in mortality due to any causes was demonstrated. At the same time, there are no standardized approaches to the treatment of uremic itching. There is also a special category of patients receiving antitumor therapy and developing dermatological adverse events, also potentially accompanied by itching.
This article presents a case of uremic pruritus in a patient with papulo-pustular cutaneous reaction (grade II on a Scale Common Terminology Criteria for Adverse Events, CTCAE v 5.0) to the epidermal growth factor (EGFR) inhibitor cetuximab in combination with leucovorin and 5-fluorouracil for rectal cancer. Treatment of uremic pruritus with small doses of gebapentin (300 mg/day) led to complete regression of pruritus. Papulo-pustular rashes completely regressed after recommended systemic and topical therapy according to the severity of rush (doxycycline 100 mg 2 times a day for 5 days, cream with neomycin, natamycin and hydrocortisone 3 times a day for 7 days). Pruritus was absent during the next 6 months of follow-up. Antitumor therapy was not interrupted due to acneiform rush, and following supportive topical therapy allowed to control severity of exacerbations which did not exceed III grade according to CTCAE v 5.0 and did not require the addition of systemic therapy.
Thus, therapy of uremic pruritus with gabapentin has shown was effective also in a patient with severe comorbid pathology. Supportive topical therapy consistent with the severity of papulo-pustular rash reduced the severity of exacerbations during following EGFR inhibitor therapy.

With the economic impact and increasing popularity of the electronic gaming industry, EGS (Electronic Gaming Sports) had become an important topic of debate in sports academia regarding its conceptual delineation and attribute characteristics. This paper jumped out of the hotpot academic perspective of the concept, characteristics, and impacts of EGS. In response to the gaps in the spatial development of the EGS industry and the lack of empirical research findings, an interpretive empirical research method was adopted, focusing on Wuhan as the study area to gain insight into the situation where the spatial development of the EGS industry was unclear. The spatial evolution of the EGS industry in the main town area of Wuhan was interpreted through a quantitative approach and based on the spatial data of EGS companies from 2006 to 2022 using Average Nearest Neighbor (ANN), Kernel Density Estimation (KDE), and Ordinary Kriging (OK) of geospatial analysis. The results indicated closure to the gradual release of the EGS industry, with specific findings as follows. (1) The EGS industry in the main town area of Wuhan from 2006 to 2022 developed rapidly, and the overall spatial distribution showed a process from discrete to cluster, accompanied by an apparent deepening of aggregation in recent years. The local aggregation of the EGS industry transformed from dual to multiple cores, and the multiple cores formed stronger groups of aggregation as the cluster spread and merged. (2) The spatial interpolation of the registered capital of companies predicted the hot spot of high- capital distribution of EGS companies in the Optics Valley vice town area of Hongshan to the southeast, indicating that more competitive EGS companies and larger EGS industry groups might emerge in Optics Valley in the future. (3) The spatial evolution of the EGS industry in the main town area of Wuhan could be divided into an early start phase from 2006-2010, a rapid development phase from 2010-2014, an aggregate explosion phase from 2014-2018, and a cluster integration phase from 2018-2022. (4) The spatial evolution of the EGS industry was influenced not only by the main factors of industrial economic agglomeration, industrial chain derivation, and industrial policy environment but also by the other factors of land and talent market, adjacent infrastructure support, city industrial promotion, and globalization dissemination. The future development of the EGS industry could be guided by the government's industrial policies, supported by high-quality talent teams, and driven by local promotion and international communication to provide an essential impetus for the optimal EGS industry.

Published: September 2023

To promote the coordination and stability of supply chain finance and improve the financing environment of small and medium-sized enterprises, this paper designs a supply chain finance risk assessment and analysis platform. Combining the characteristics of a large amount of risk assessment data, a numerical analysis algorithm is introduced in the process of platform design, and the extrapolation method in the numerical analysis algorithm is used to calculate the risk assessment- related data. To make the calculation faster and the data more accurate, the central difference quotient extrapolation is used to accelerate and a downtime mechanism is introduced. Firstly, the approximation formula for the calculation is constructed, followed by the construction of a sequence of variable steps to obtain a sequence of approximations. Finally, the obtained approximate sequence values are used to construct an interpolating polynomial, and the constant term of the polynomial, which is the final risk factor, is obtained through continuous iteration. To verify the effectiveness of the numerical analysis-based algorithm in supply chain financial risk assessment, the simulation results show that the risk assessment accuracy of the numerical analysis-based supply chain financial risk assessment platform is as high as 99% and the time required is 17 seconds higher than other assessment models, which verifies that the numerical analysis algorithm can improve the accuracy and rapidity of risk assessment.

Let χ(G) denote the chromatic number of a graph G. Under the proper coloring of a graph G with χ(G) colors, we define a signed graph from it. The obtained signed graph is defined as parity colored signed graph and denoted as Sc. The signs of edges of G are defined from the colors of the vertices as +( − ) if the colors on the adjacent vertices are of the same (opposite) parity. In this paper, we initiate a study on Sc. We further investigate the chromatic rna number of some classes of graphs concerning proper coloring.
