Published: October 2023

Heavy metal pollution poses an environmental risk, and its efficient removal and facile separation from water remains a challenge. Magnetic iron oxide, an eco-friendly, relatively stable, and easy-separation material, has been regarded as one of the most applicable adsorbents for water treatment. However, the limited adsorption capacity has restricted its applications. Herein, sulfur-doped magnetic Fe3O4 (Sx–Fe3O4) adsorbent was fabricated using a calcination method for the efficient removal of Pb(II) from water. In contrast to undoped Fe3O4, the introduction of doped sulfur greatly enhanced the adsorption performance of S–Fe3O4 over four times, with a maximum capacity of 333.33 mg g−1, which was synthesized at 300 °C with a raw molar ratio of S–Fe of 5. Based on the structure and morphology analysis, it was demonstrated that sulfur was successfully doped into the Fe3O4 structures, which resulted in Fe3O4 with active sulfur sites accordingly contributing to the adsorption enhancement through the combination of strong soft–soft interactions between soft base sulfur and soft acid Pb(II) along with surface adsorption. Sx–Fe3O4 could maintain the adsorption performance in the presence of competing ions. Furthermore, although the sulfur doping process exhibited slight side effects on the magnetic property, magnetic Sx–Fe3O4 maintained the high separation potential. This study presented a promising strategy to enhance the adsorption performance of Fe3O4 through sulfur doping for Pb(II) removal from water.
Numerical Simulation and Application of a Channel Heat Sink with Diamond Ribs
Authors: Zhang Dongxu , Liu Guoqiang , Lai Yongkang , Lin Xiaohui , Cai Weihuang
Published: October 2023

This paper presents a channel radiator with ribbed ribs and primarily investigates the fluid flow and heat-transfer characteristics of the channel radiator. A three-dimensional numerical simulation of the radiator’s pressure-drop and heat-transfer process was conducted using the finite volume method. A comparison between the experimental data and the simulation results demonstrates that the simulation in this paper is accurate, with a maximum error not exceeding 5%. Furthermore, the radiator was further subjected to geometric parameter studies, principally including the height ratio between the fins and the channel, the fin angle, and the spacing between the fins. The thermal resistance, Nusselt number, friction factor, and heat-transfer enhancement factor were calculated. The results indicate that if the geometric parameters are selected appropriately, the heat sink will enhance heat-transfer performance within an acceptable pressure drop. When the Reynolds number is greater than 507.5, the height ratio of 25%, the rib angle of 135°, and the rib spacing of 2.5 mm can be given priority. This heat sink is used in PCR devices, and experimental results show that the novel channel heat sink can meet the heat dissipation requirements of the TEC during the PCR process.
Efficiency Comparison of Electric Wheel Loader Powertrains with Dual Motor Input in Distributed Driving Modes
Authors: Fei Xiaotao , Han Yunwu , Wong Shaw Voon , Azman Muhammad Amin
Published: October 2023

The presented research on electric wheel loaders lacks a detailed analysis of drive energy-saving during the shovel preparation phase, which is characterized by a high probability of loader tire skidding. To address this issue, this study examines the energy consumption efficiency of a two-motor distributed drive wheel loader under three drive modes including front motor drive, rear motor drive, and dual-motor drive, taking into account the change in the drive force demand caused by the bucket landing. This study finds that the motor energy conversion efficiency is the greatest in single-motor drive mode when the bucket does not generate positive pressure with the ground. In dual-motor drive mode, the total torque overcome is greater, but the motor energy conversion efficiency is the greatest when the bucket generates the greatest positive pressure with the ground. This study suggests that in future designs of electric loaders, two motors can be used to distribute the drive, but the front and rear motors should be designed to participate in the drive with a certain torque distribution ratio at different speeds and resistance to avoid the phenomenon of the bucket pressing the ground too much.

Published: October 2023

Background

Contemporary general practice includes many kinds of remote encounter. The rise in telephone, video and online modalities for triage and clinical care requires clinicians and support staff to be trained, both individually and as teams, but evidence-based competencies have not previously been produced for general practice.

Aim

To identify training needs, core competencies, and learning methods for staff providing remote encounters.

Design and setting

Mixed-methods study in UK general practice.

Method

Data were collated from longitudinal ethnographic case studies of 12 general practices; a multi-stakeholder workshop; interviews with policymakers, training providers, and trainees; published research; and grey literature (such as training materials and surveys). Data were coded thematically and analysed using theories of individual and team learning.

Results

Learning to provide remote services occurred in the context of high workload, understaffing, and complex workflows. Low confidence and perceived unmet training needs were common. Training priorities for novice clinicians included basic technological skills, triage, ethics (for privacy and consent), and communication and clinical skills. Established clinicians’ training priorities include advanced communication skills (for example, maintaining rapport and attentiveness), working within the limits of technologies, making complex judgements, coordinating multi-professional care in a distributed environment, and training others. Much existing training is didactic and technology focused. While basic knowledge was often gained using such methods, the ability and confidence to make complex judgements were usually acquired through experience, informal discussions, and on-the-job methods such as shadowing. Whole-team training was valued but rarely available. A draft set of competencies is offered based on the findings.

Conclusion

The knowledge needed to deliver high-quality remote encounters to diverse patient groups is complex, collective, and organisationally embedded. The vital role of non-didactic training, for example, joint clinical sessions, case-based discussions, and in-person, whole-team, on-the-job training, needs to be recognised.

Farmacocinética del factor VIII en el tratamiento de la hemofilia: lo que el hematólogo clínico debe saber
Authors: Castañeda-Hernández Gilberto , Majluf-Cruz Abraham
Published: October 2023

The pharmacokinetics of biological drugs, which are recombinant proteins, differs from that of conventional drugs, which are small molecules. The recombinant factor VIII replacement therapy is the current standard treatment for hemophilia A. Due to the high variability of the pharmacokinetic parameters, it is recommended to individualize the dosage of factor VIII, both in its unpegylated and in its extended half - life pegylated form. Understanding the processes involved in pharmacokinetics and the meaning of the parameters that describe it allows us to understand what happens when administering a factor VIII - based drug.

Published: October 2023

People with cancer are at increased risk of developing venous thrombosis and rethrombosis (despite treatment), as well as at an increased risk of bleeding. The causes of thrombosis and bleeding vary among patients, tumor types, and cancer treatments. Cancer-associated venous thrombosis (CAVT) causes morbidity, delays in cancer treatment, impairment of quality of life and of emotional state, and increased mortality. Approximately one in ten individuals with cancer die from pulmonary thromboembolism. Reducing the risk of thrombosis in surgery, hospitalization, and in outpatients with cancer is possible with targeted, risk-based thromboprophylaxis. Treatment of CAVT should be individualized in terms of type of anticoagulant, dose, duration of treatment, and modifications of anticoagulation during invasive procedures. These guidelines present a framework for the comprehensive management of patients with cancer and venous thrombosis.
Using Gamification to Develop Students As Strategic Thinkers – A Qualitative Perspective
Authors: O'Brien Michael , Costin Yvonne
Published: October 2023

The use of gamification as an instructional strategy has gained significant attention in recent years as a way of increasing student engagement and motivation. Gamification involves the application of game design principles to non-game contexts, such as higher education. One area in which gamification has shown particular promise is in developing students' strategic thinking abilities. This qualitative study explores university students' post-module reflections on their experience of working in teams over the course of a seven-week intensive postgraduate business analytics simulation module. Reflections were analysed using thematic analysis to identify common themes and patterns with respect to students’ strategic thinking in terms of decision-making. The study findings strongly suggests that gamification, particularly the use of business simulations, can be an effective tool for developing students' strategic mindsets, in terms of the process for decision-making, impact of critical incidents, the lessons they learned and corrective action taken, along with the role of the team itself.
Mužské postavy v prozaickom svete Vandy Rozenbergovej
Authors: Bariaková Zuzana
Published: October 2023

The paper analyses the depiction of male characters in the selected texts of the Slovak author Vanda Rozenbergová. Most of the attention is focused on a specific set of problems – on young/adolescent male characters within certain family and partner configurations and on the segments of childhood/adolescence displayed in Rozenbergová’s three books: Slobodu bažantom (Freedom to Pheasants) (2015), Muž z jamy a deti z lásky (The Man out of a Hole and the Children out of Love) (2017), and Zjedol som Lautreca (I Ate Lautrec) (2021), not only because they offer a very good insight into her general style of writing, but also due to her assessment of the character/hero of our times and forms of masculinity in contemporary literature. The interpreted prose largely deals with adolescence as an important period during which the a child turns into an adult. Rozenbergerová’s non-adult protagonists often represent the cathartic aspect of an insensitive society which lacks the sense of fellowship as well as empathy. Their meaning of life and its value is represented by almost epistemological privilege in the child’s ability to see what cannot be seen by the adult.
Hľadanie identity alebo prečo sa (ne)oplatí dospieť. Chlapčenský protagonista v próze pre mládež po r. 1989
Authors: Pršová Eva
Published: October 2023

The social, political, and cultural changes after 1990 brought thematic and expressive innovations and transformations to young adult literature in Slovakia. In comparison with the previous decades, a completely different reality is modelled in fiction primarily through the character, relationships, and environment. In the literary image of many writers, a partially safe world before the upheaval is replaced by the incomprehension, emptiness, destruction and even toxicity of one's own family. The protagonists, thus, suffer from a lack of emotional and material support and escape into addictions or a substitute virtual reality. The prose of P. Holka, P. Andruška, P. Glock and J. Šebesta has become a means of criticising a new society and an opportunity to introduce both adult and child readers to a wide range of linguistic elements of modern prose through the urgent subjective narratives of the youngsters. The text also reflects on the father figure, who often finds himself at the opposite pole to the patriarchal breadwinner of the family.
Obraz relacji ojca i syna w powieści Próchno Wacława Berenta
Authors: Świętuchowska Wiktoria
Published: October 2023

This article is an attempt to explore the difficult relationship between two artists – father and son in Wacław Berent's novel Próchno. In the first part of the article, I focus on presenting the biography of Wacław Berent before explaining the structure of the novel. The problematic analysis of the chosen topic begins with the presentation of one of the main characters of Próchno, Władysław Borowski. Władysław is an example of a character whose relationship with his father has a significant impact on the quality of both life and decisions made. Due to their completely different attitude to life, both father and son become interesting subjects for interpretation. Berent's novel describes the hardships of artists struggling with decadent reality.
Na ceste k dospelosti (román Dmitrija Bykova "Jún")
Authors: Lizoň Martin
Published: October 2023

The paper analyses the coming-of-age process of Mikhail Gvirtsman, the main character of the first part of the novel June by Dmitry Bykov. It analyses his moral misdemeanours and growing tension between rational (social rules and moral principles) and irrational (aggressive, bodily) actions. The transformation of the character and his actions are interpreted via a set of factors that occur in the character’s life as a direct result of the story’s setting. The analysed character is directly influenced by a specific historical context and that is why the paper also briefly analyses fiction as a way of alternative interpretation of historical events, the way of historical memory is being fixed or (re)constructed in fiction. The novel, analysed mainly from the main character’s perspective, is therefore – through its explicit, although incomplete, parallels – viewed as a reflection (allegory) on contemporary Russia.

This article is devoted to the study of the representation of Soviet masculinity in the novel Kremulator by the Russian-speaking Belarusian writer Sasha Filipenko. On the example of the male images of the novel, the main features of the “traumatized masculinity” inherent in the gender policy of the Stalinist regime are considered. Signs of a “masculinity of trauma”,vulnerability, powerlessness and deprived sexuality, are revealed.
Der moderne Mann auf der Reise… Hanns-Josef Ortheils Sizilien
Authors: Grzywka-Kolago Katarzyna
Published: October 2023

Hanns-Josef Ortheil wrote two works set in Sicily: Das Kind, das nicht fragte (2012) and Die Insel der Dolci. In den süßen Paradiesen Siziliens (2015). The first of these is a novel with autobiographical elements, while the second consists of a travel story depicting events experienced by the writer while exploring the island. What the two texts have in common is both a reflection on the specifics of Sicily and ‘sicilianness’, and a fable-like quality of the island’s representation, although that quality means something slightly different in each piece.

Published: October 2023

The object of the study is the social relations arising during the prosecutor’s super-vision over entrepreneurial activity. The study aims to analyze the status of an individual entrepreneur as a subject of legal relations arising during the prosecutor’s supervision over law enforcement and civil rights provision. The subject of the study is materials from prosecutor’s and law enforcement practice, statisti-cal data on the issue of law violation by an individual entrepreneur, regulations of legislation in force, and academicians’ perspectives on the matter. The authors emphasize contradictions in viewpoints on the issue of the possibility to supervise law implementation by individual entrepreneurs and the ambiguity of legal regulation of an individual entrepreneur’s status. At the same time, according to the data provided, there is no doubt about the need for a prosecutor to supervise how individual entrepreneurs follow the law, given the latter’s substantial number of law violations. The results of the study demonstrate that the legal status of individual entrepreneurs as special subjects of legal relations requires particular regulation. The authors suggest adding individual entre-preneurs in the list of subjects in “Subject of the Supervision” in Article 21 Part 1 and Article 26 Part 1 of the Law on prosecution due to the specificity of such subjects’ legal status, which differs from that of individuals and legal entities, and the need to provide prosecutor’s supervision.

Published: October 2023

The article discusses the foundation for the establishment and legal regulation of monitoring the state of the native habitat and the ecological situation in areas of traditional residence and traditional economic activity of indigenous peoples, as well as the directions that contribute to the creation of the necessary conditions for the activity of indigenous peoples in such monitoring. To access the state of the indigenous peoples’ habitat, it is possible to use data obtained from the state environmental monitoring, social and hygienic monitoring, monitoring that incorporates state control (supervision), and independent monitoring of the environment’s state carried out by the individuals of the indigenous peoples. The author suggests the improvement of legal regulation in terms of defi-nition and legal consolidation of the concept of monitoring the state of the native habitat and the ecological situation in areas of traditional residence and traditional economic activity of indigenous peoples.

EXAMINING THE EFFECTS OF EMPLOYEES' VISIONARY LEADERSHIP PERCEPTIONS ON ORGANIZATIONAL AGILITY WITH STRUCTURAL EQUATION MODEL: A RESEARCH IN AVIATION SECTOR
Authors: YILMAZ Rabia
Published: October 2023

Visionary leaders are leaders who shape the future in the direction of their goals and realize their attitudes and actions in this direction. In this situation visionary leaders struggle to obtain positive outputs from the internal and external environment of the organization, especially in a framework required by continuous change, which is a necessity of the time. One of these positive outcomes is organizational agility. The aim of this study is to illuminate the effect of visionary leadership behavior, one of the modern leadership theories that emerged together with the necessities of the time, on organizational agility. The research was performed on 308 non-managerial white-collar employees working in aircraft leasing companies operating within the structure of general aviation organizations throughout Turkey. Questionnaires were conducted by face-to-face interview method. In the study firstly, the “Visionary Leadership Scale” measured by Sashkin (1996) and transformed into Turkish scale by Tanrıbil (2015), and also, “Organizational Agility Scale” measured by Sharifi and Zhang (1999) and transformed into Turkish scale by Akkaya and Tabak (2018) were used. Analysis results were created using SPSS 23 and Amos 24 applications. In this context in the study, frequency analysis, factor analysis, and reliability analysis, descriptive statistics, and correlation analysis were applied. Additionally, Structural Equation Models (SEMs) analysis was used to test the confirmatory factor analysis, goodness of fit values and coefficients values related to the variables. The research findings showed that visionary leadership and organizational agility has a positive and significant relationship. In addition, a partial effect of visionary leadership on organizational agility was found. Regarding the sub-dimensions, it was determined that communication and risk have effects on flexibility; communication, risk, respect, and focus have effects on response; reliability, respect, and focus have effects on competence; and risk and focus have effects on speed.
Architectural Strategy Development Through Evaluation of the Spatial Themes Prominent in the Formation of Istanbul's Identity from 1923 to the Present: Proposal of a Model
Authors: CUBUK Gencay
Published: October 2023

The core of the study is to capture a commonality between the themes that determine the spatial character of Istanbul and to present the change in the prominent spatial themes from the foundation of the republic to the present and to propose a model for developing an architectural strategy with the help of this change. This change was shaped by spatial preferences, class differences, socio-economic and cultural variables of the period and played a major role in determining the settlement of residences, industry-education-health structures and social areas. The scope of the study consists of the works of leading figures working on the construct ion of the thematic identity of metropolises and urban history. The method of the study consists of literature research that will make these studies and the effective links between them visible, and a data analysis that will provide a breakdown of prominent themes, based on twenty-year periods, and aiming to present the relationships between related thematic words. The findings of the study show that industrialization, housing supply and demand, squatting, socio-cultural life, urban population planning, interaction areas, imported designs and approaches have both an autonomous and interrelated place in the construction of Istanbul's hybrid urban identity. Separate thematic areas such as industrialization and housing trigger processes that directly affect each other's development. As a result, it is seen that the breaking processes of the transformation of the prominent spatial themes in Istanbul offer some forms of association that can provide references for future design products. Sharing comprehensive inferences about these processes with institutions for development and diversification will play an active role in developing new themes that can contribute to Istanbul's urban identity and increasing the agility of relating the current urban identity with contemporary possibilities.

Bu araştırma kapsamında öğretmen eğitimi programlarının nasıl deneyimlendiği öğretmen adaylarının gözünden açıklanmaya çalışılmıştır. Durum çalışması ile desenlenen araştırmanın verileri 1997, 2006 ve 2018 yıllarında uygulamaya konulan öğretmen eğitimi programlarında öğrenim gören 44 öğretmen adayı ile gerçekleştirilen yarı yapılandırılmış görüşmeler ve doküman incelemesi ile toplanmıştır. Araştırma sonucunda üç farklı programın meslek bilgisi boyutunun uygulanışına dair benzer sorunların yaşandığı görülmüştür. Bu sorunlar arasında derslerin kuramsal ağırlıklı yürütülmesi ve uygulamaya daha az yer verilmesi, kullanılan öğretim yöntem-tekniklerin etkili olmayışı, sınıfların kalabalıklığı, derslerin özel alan ile ilişkilendirilememesi sayılabilir. Öte yandan öğretmenlik meslek bilgisi derslerine ilişkin olumlu görüşlerin arttığı, özellikle öğretim elemanlarının olumlu ve destekleyici tavırlarının derslerin önemsenmesinde etkili olduğu görülmüştür. Meslek bilgisi dersleri öğretmen adaylarına öğretmenlik mesleğine dair bilgi ve becerilerin yanında olumlu tutum ve değerlerin kazandırılması beklenen derslerdir. Bu doğrultuda, derslerin öğrenme-öğretme sürecine yönelik düzenlemelerde öğretmen adaylarının deneyimleri ve beklentilerini dikkate almanın derslerin niteliğini ve işlevini artıracağı düşünülmektedir.
TRABALHO DAS PROFESSORAS COM DEFICIÊNCIA VISUAL E DAS EDUCADORAS DA INCLUSÃO ESCOLAR

Published: October 2023

Este artigo discute a construção do trabalho colaborativo entre Professoras com deficiência visual e Auxiliares de Apoio ao Educando em escolas da rede municipal de ensino de Belo Horizonte. Os dados produzidos em campo foram consequência de entrevistas semiestruturadas, observação participante e uma pergunta geradora no que diz respeito à história de vida tópica das duas Professoras que foram interlocutoras da pesquisa. O recorte justifica-se por tratar especificamente dos percursos formativos e da atuação das Professoras no mundo do trabalho.  O texto estabelece-se com uma abordagem aproximativa entre os dados produzidos em campo e a noção ergológica de “Entidades Coletivas Relativamente Pertinentes - ECRP”, sobretudo a partir de autores como Schwartz e Durrive (2010) e Efros (2014). Depreende-se que uma abordagem aproximativa entre os resultados produzidos em campo e o conceito de (ECRP) possibilita compreender o trabalho realizado por Professores/Professoras com deficiência e seus/suas Auxiliares como uma parceria construída como uma ECRP, sendo importante e necessário considerar o papel do/da Auxiliar de Apoio ao Educando no processo educacional, ainda que este profissional não substitua o Professor com deficiência. Tem-se, portanto, na mediação da relação professor/aluno, um novo sujeito sociocultural, sujeito este que não é aluno, nem Professor, mas que igualmente é ativo no processo educacional. Vislumbra-se para este profissional um novo termo que, de fato, qualifique e evidencie seu trabalho, qual seja, Educador da Inclusão Escolar.
Low thermal budget V/Al/Mo/Au ohmic contacts for improved performance of AlGaN/GaN MIS-HEMTs

Published: October 2023

We report on the highly improved performance of Al2O3/AlGaN/GaN MIS-HEMTs using a V/Al/Mo/Au metal stack as ohmic electrodes. Transfer length method test structures using a V/Al/Mo/Au metal stack annealed at a temperature of 660 °C revealed highly linear current–voltage curves and smooth surface morphology. Compared with reference MIS-HEMTs using Ti/Al/Mo/Au annealed at the standard rapid thermal annealing temperature of 880 °C, V-based devices exhibited less hysteresis of transfer curves and showed higher gate controllability of the drain current, suggesting a highly improved Al2O3/AlGaN interface. Measurements and analyses of capacitance–voltage characteristics of corresponding MIS-capacitors corroborated these findings. The V-based ohmic contact could open new avenues towards enhanced GaN-based MIS-HEMTs performance.
Bimetallic metasurface broadband perfect absorber for high-efficiency thermal photovoltaics
Authors: Du Wei , Wang Qianqian , Yan Zhendong , Xu Xiulian , Xu Xiaoyong , Hu Jingguo
Published: October 2023

We theoretically propose and demonstrate that broadband polarization-insensitive perfect visible light absorption can be realized in a periodic bimetallic nanotriangle structure with a thick gold plate. The average absorption is 95.79% from 400 nm to 800 nm. The multiple localized surface plasmon resonances of the bimetallic nanostructure are the major contributions to this broadband perfect absorption in the visible region. Meanwhile, the physical mechanism of the broadband perfect absorption of the bimetallic nanostructure can be well interpreted by impedance matching theory. Moreover, the average photo-thermal conversion efficiency is up to 93% over a wide temperature range.
Detection and Molecular Characterization of Canine Coronavirus Based on Partial Membrane Gene Sequences
Authors: Karapınar Zeynep , Timurkan Mehmet Ozkan
Published: October 2023

Canine coronavirus (CCoV) infection in dogs is common all over the world and progresses with gastroenteritis findings. Infection as a result of complications with secondary factors may result in death, especially in puppies. The virus, which is excreted in the feces, spreads indirectly through the contamination of food, water, and the environment. This study, it was aimed at revealing the CCoV infection and obtaining current molecular information about the infection. In addition, molecular characterization of CCoV strains circulating in the region was made based on the M (membrane protein) gene. The study material consisted of stool samples from 12 dogs with gastroenteritis findings. The amplified PCR products were subjected to sequence analysis and a phylogenetic tree was constructed by comparing them with different reference CCoV isolates from GenBank. In the phylogenetic tree, 1 of the 5 positive samples was determined to be CCoV-I, and 4 samples were determined to be CCoV-IIa. It was determined that the strains obtained were 85.4 - 97.7% similar among themselves and 82.7-98% similar to other strains obtained from GenBank. As a result of study, current molecular information about CCoV circulating in the Balıkesir region was obtained. With this study, it is thought that new research on the existence and molecular epidemiology of CCoV infection in Türkiye will make important contributions to vaccine studies and the control of infection.

Kulit buah naga berpotensi sebagai sumber pewarna makanan karena mempunyai pigmen betasianin, yang memberikan warna merah dan ungu yang menarik pada makanan.  Pada ekstraksi pigmen pewarna biasanya dilakukan dengan pemanasan, akan tetapi hal ini dapat menganggu stabilitas pigmen betasianin. Teknologi ekstraksi terkini, seperti ekstraksi dengan bantuan gelombang mikro atau teknik elektromembran, tegangan listrik dapat digunakan untuk meningkatkan efisiensi dan kecepatan proses ekstraksi. Penelitian ini bertujuan untuk mengetahui pengaruh variasi tegangan ohmik (50V, 60V, 70V, 80V) terhadap konduktivitas listrik, suhu dan karakteristik mutu pewarna kulit buah naga. Pemanasan konvensional juga dilakukan sebagai perbandingan/kontrol. Analisis statistik menggunakan One Way Analysis of Variance dan uji lanjut Tukey. Hasil penelitian menunjukkan bahwa perlakuan tegangan yang berbeda mempengaruhi laju perubahan suhu, konduktivitas listrik, warna (L, a, b), dan total padatan terlarut, akan tetapi tidak mempengaruhi pH, rendemennya. Konduktivitas listrik meningkat secara eksponensial dengan meningkatnya suhu.

The article presents the results of a survey of 26 production batches of rapeseed cake and meal for microscopic fungi and mycotoxin contamination. The indicator of the total number of fungi in most samples corresponded to the regulated norm of 5000 CFU/g, Penicillium spp., Aspergillus spp. prevailed in the composition of the mycobiota, Cladosporium spp., Scopulariopsis spp. were detected less often, and flour fungi and yeasts were found in small amounts. The presence of the anthraquinone toxin emodin in all samples was established by the method of indirect competitive enzyme immunoassay, alternariol, mycophenolic acid and ergoalkaloids were detected somewhat less frequently, in isolated cases – aflatoxin B1, cyclopiazonic acid and T-2 toxin. The prospects for further research and the need to assess the potential of toxin formation by sanitary-significant micromycetes are discussed.

Three-dimensional (3D) printed railroad tracks can properly address the rendering of a variety of topographic profiles of naturally occurring landscapes and reduce construction costs. Load tests of PLA railroad tracks found that web failure is a dominant failure mode. This paper evaluates the web stiffening strategies of additively fabricated PLA railroad tracks for rail-guided, micro-people movers (MPMs). To strengthen the track web, web-widening with additional PLA material and stiffening using composite reinforcement using glass fiber reinforced polymer (GFRP) wrap have been investigated. The composite wrapping technique was conducted by bonding fiberglass cloth to both sides of the web using a polymeric resin. Flexural load tests were conducted on the specimens with different infill volume percentages. A linear trend was observed on the peak bending capacities of specimens with PLA infill fiber contents ranging between 20% to 100%. Different failure modes were observed for the different percentage specimens during the tests. When compared to their unreinforced counterparts, the 60% infill specimen had the largest increase in strength about 1,500 N in bending with the addition of GFRP wrap. The tangent stiffnesses of all samples were calculated which showed the 100% infill specimen had the highest increase of approximately 50%. The wrapping reinforcement was found to significantly modify the failure mechanisms of the 3D-printed tracks with different infill volume percentages. The strengthening of the 3D-printed tracks using GFRP wrapping is also shown to be similar to the widening of web sections of the additively printed railroad tracks.
