Development of an Omnidirectional AGV by Applying ORB-SLAM for Navigation Under ROS Framework
Authors: Wu Pan-Long , Li Jyun-Jhen , Shaw Jinsiang
Published: March 2023

The development of an automated guided vehicle with omni-wheels for autonomous navigation under a robot operating system framework is presented in this paper. Specifically, a laser rangefinder-constructed two-dimensional environment map is integrated with a three-dimensional point cloud map to achieve real-time robot positioning using the oriented features from accelerated segment test and rotated binary robust independent elementary feature detector-simultaneous localisation and mapping algorithm. In the path planning for autonomous navigation of the omnidirectional mobile robot, we applied the A* global path search algorithm, which uses a heuristic function to estimate the robot position difference and searches for the best direction. Moreover, we employed the time-elastic-band method for local path planning, which merges the time interval of two locations to realise time optimisation for dynamic obstacle avoidance. The experimental results verified the effectiveness of the applied algorithms for the omni-wheeled mobile robot. Further, the results showed a superior performance over the adaptive Monte Carlo localisation for robot localisation and dynamic window approach for local path planning.

Martians in the favela: religion and revolution in Rio de Janeiro
Authors: Rom Michael
Published: March 2023

Research on Marxism as a religious movement has primarily focused on its theological implications. Building on this work, this article instead examines the practical aspects of revolutionary Marxism as a religious experience during the Latin American Cold War, and compares it to two other non-Christian religious traditions, Judaism and Umbanda. Drawing on secret police records, memoirs and oral history interviews, this article explores the influence of Judaism, Marxism and Umbanda on the anti-dictatorship activism of Alfredo Syrkis. Through an analysis of Syrkis’s life history, it assesses his conversion from liberal anticommunism to revolutionary Marxism, his participation in Marxist proselytising as a high school activist and his political activity in the clandestine Marxist organisation Revolutionary Popular Vanguard (VPR), highlighting group dynamics that were comparable to millenarian movements. It also considers the importance of other religious traditions in Syrkis’s life, including Judaism, the religion of his parents that equipped him with valuable social ties, and Umbanda, a syncretic Afro-Brazilian religion that Syrkis turned to during times of extreme anxiety in the armed struggle. This article argues that the religious traditions of Judaism, revolutionary Marxism and Umbanda influenced Syrkis’s political activism in both complementary and competing ways. While none of these traditions were able to command Syrkis’s undivided loyalty, collectively they informed the terms of his engagement with and disengagement from the Brazilian armed struggle against military rule. By analysing Syrkis’s life history through the lens of religion, this article broadens the study of cultures of militancy during Latin America’s Cold War.

Introduction: Globally, mental health problems have affected nearly 1 billion people and approximately 1 in 10 Mexicans. The detection and surveillance of depression, anxiety, and stress in Mexico requires more reliable and valid instruments. Objective: To determine the factor validity and internal consistency of the Depression, Anxiety, and Stress Scale-21 items (DASS-21) in a non-probabilistic national sample of Mexican adults. Method: Cross-sectional study by means of an online survey of 1 613 Mexican adults aged 18 years and older. The Spanish version of the DASS-21 was used, which evaluates the presence of depressive symptoms, anxiety, and stress. Factor validity was determined by comparing different confirmatory factor analysis models: one-dimensional, three factors (correlated and non-correlated), second order,and bifactor. Results: The application of the bifactor model to the DASS 21, supports its validity for identifying the presence of symptoms of depression, anxiety, and stress, as well as an altered general emotional state in a sample of Mexican adults. Conclusions: The DASS-21 is a theoretically robust instrument useful for research and clinical practice.

Introduction: Internet addiction results in intense and frequent use. There is a gap in the literature in relation to the unawareness of problematic Internet use (PIU) in predicting Internet use time (IUT). Objective: To identify sociodemographic/psychological variables contributing and moderating IUT. Participants: 1,270 participants of the European Social Survey (EES), Round 8. Instruments: EES variables assessing Internet use (IU), health perception, well-being, social life, and sociodemographic variables, underlying the construct. Results: Age, education, sources of household income, social activities compared to others of the same age and subjective general health explain IU per day; and age, years of education, domicile and socially meeting with other people with whom to discuss intimate matters explain IU per week. Education was found to be a significant moderator in the relationship between subjective general health and IU per week; and in the relationship between socially meeting with other people and IU per day. Discussion: Maladaptive IU, when the perception of health is worse, and adaptive IU, when the perception of social life is better, are both suggested, depending on education. Conclusions: These findings point to the need to study IUT involving educational level, keeping in mind that what may be PIU at one educational level may not be the case at another.
Klingende Subjekte
Authors: Scheuermann Anita
Published: March 2023

Gesang und Musik erfahren im Kontext moderner Spiritualität, Freizeit und Therapie einen bemerkenswerten Boom. Die Akteur*innen, Diskurse und Praktiken fassen Gesang vielfach als Medium zur »Heilung« auf. Dies führt zu vielfältigen Thematisierungen ästhetisierter Selbstverhältnisse in einer als verstummt wahrgenommenen Welt. Anita Scheuermann fokussiert auf die Beziehung zwischen diskursiv verhandelten klingenden Subjektmodellen und tatsächlichen Subjektivierungen. Damit leistet sie einen empirischen Beitrag zu Subjektivierungsforschung, Ästhetisierungsprozessen und Entwicklungen religiös-therapeutischer Gegenwartskultur.
Nature of Science als Grundlage einer Wissenschaftsdidaktik der Naturwissenschaftsdidaktiken
Authors: Büssing Alexander Georg , Nehring Andreas , Bruckermann Till
Published: March 2023

Die Naturwissenschaftsdidaktiken befassen sich mit schulischem und außerschulischem Lehren und Lernen über Naturwissenschaften vom Kindes- bis zum Erwachsenenalter. Zur Grundlegung einer Wissenschaftsdidaktik der Naturwissenschaftsdidaktiken wird das etablierte Konzept der Natur der Naturwissenschaften (engl. Nature of Science) auf die Naturwissenschaftsdidaktiken bezogen. Eine solche Natur der Naturwissenschaftsdidaktiken könnte die Grundlage für eine weitere Reflexion der Disziplinen mit Implikationen für die Hochschuldidaktik und die Professionalisierung sein. Beispielhaft für diese Implikationen wird das Verhältnis von wissenschaftlicher Forschungs- und Unterrichtspraxis thematisiert. Auch wenn der hier vorgeschlagene Ansatz der Natur der Naturwissenschaftsdidaktiken noch explorativ ist, könnten gerade die sozial-institutionellen Aspekte eine wichtige Ergänzung bestehender Ansätze einer Wissenschaftsdidaktik der Naturwissenschaftsdidaktiken darstellen.
Das Tier im Bild
Authors: Zenker Friederike
Published: March 2023

Die Ethik im Umgang mit Tieren braucht mehr als das Gespräch über Rechte und Pflichten. Friederike Zenker zeigt auf, wie wichtig unsere Wahrnehmung für die Mensch-Tier-Beziehung ist und welche Rolle Bilder dabei spielen. Ihre Analyse exemplarischer Fotografien verbindet Elemente der Ethik und der Ästhetik miteinander und verdeutlicht, dass Tiere nicht nur als Vertretende einer Art, sondern vielmehr als nicht austauschbare Individuen gesehen werden können. Dieser zentrale Pfeiler zeitgemäßer Beziehungen zu Tieren wird im Begriff der »tierlichen Singularität« zusammengefasst - eine Einladung an verschiedene Disziplinen, ihre Sichtweisen auf die Tierethik zu erweitern.
Glucagon and exenatide improve contractile recovery following ischaemia/reperfusion in the isolated perfused rat heart

Published: March 2023

The inotropic effects of glucagon have been recognized for many years, but it has remained unclear whether glucagon signaling is beneficial to cardiac function. We evaluated the effects of glucagon alone and in combination with the glucagon‐like peptide 1 (GLP‐1) receptor agonist exenatide in the isolated perfused rat heart. The isolated perfused rat heart was used to investigate the initial inotropic and chronotropic effects of glucagon and exenatide during aerobic perfusion, and recovery of contractile function following ischaemia/reperfusion. Glucagon, but not exenatide, elicited an acute chronotropic and inotropic response during aerobic perfusion of the rat heart. Compared with control, glucagon improved recovery of left ventricular developed pressure (LVDP) by 33% (p < 0.05) and rate‐pressure product (RPP) by 66% (p < 0.001) following ischaemia/reperfusion and amplified the mild recovery enhancement elicited by exenatide in a dose‐dependent manner. Glucagon shows inotropic properties in the isolated perfused rat heart and improves contractile recovery following ischaemia/reperfusion, both alone and when co‐administered with a GLP‐1 receptor agonist. Glucagon and exenatide, a GLP‐1 receptor agonist, combine to stimulate greater recovery of postischaemic contractile function in the Langendorff heart. Glucagon was inotropic and chronotropic, yet this initial effect decreased over time and did not account for the increased contractility observed postischaemia/reperfusion.

Mechanosensitive TRPV4 channel plays a dominant role in maintaining [Ca2+]i homeostasis and flow‐sensitive [Ca2+]i signaling in the renal tubule. Polycystic kidney disease (PKD) manifests as progressive cyst growth due to cAMP‐dependent fluid secretion along with deficient mechanosensitivity and impaired TRPV4 activity. Here, we tested how regulation of renal TRPV4 function by dietary K+ intake modulates the rate of cystogenesis and mechanosensitive [Ca2+]i signaling in cystic cells of PCK453 rats, a homologous model of human autosomal recessive PKD (ARPKD). One month treatment with both high KCl (5% K+) and KB/C (5% K+ with bicarbonate/citrate) diets significantly increased TRPV4 levels when compared to control (0.9% K+). High KCl diet caused an increased TRPV4‐dependent Ca2+ influx, and partial restoration of mechanosensitivity in freshly isolated monolayers of cystic cells. Unexpectedly, high KB/C diet induced an opposite effect by reducing TRPV4 activity and worsening [Ca2+]i homeostasis. Importantly, high KCl diet decreased cAMP, whereas high KB/C diet further increased cAMP levels in cystic cells (assessed as AQP2 distribution). At the systemic level, high KCl diet fed PCK453 rats had significantly lower kidney‐to‐bodyweight ratio and reduced cystic area. These beneficial effects were negated by a concomitant administration of an orally active TRPV4 antagonist, GSK2193874, resulting in greater kidney weight, accelerated cystogenesis, and augmented renal injury. High KB/C diet also exacerbated renal manifestations of ARPKD, consistent with deficient TRPV4 activity in cystic cells. Overall, we demonstrate that TRPV4 channel activity negatively regulates cAMP levels in cystic cells thus attenuating (high activity) or accelerating (low activity) ARPKD progression.

The study area is situated in the central part of the Western Desert of Egypt between latitude 28°00′ to 30°00′ N and longitude 25°00′ to 30°00′ E. That region is distinguished by a featureless plain that is divided by depressions in Siwa, Qattara, and Bahariya. The purpose of the current study is to study the predominant structures in the area and how they relate to basin structure. Utilizing aerogravity data (Bouguer gravity, residual gravity, downward continuation, and Euler deconvolution) and aeromagnetic data (reduced to the northern Pole [RTP] anomalies and tilt derivative) is essential to accomplish this purpose. Through both qualitative analyses, these data were submitted to various processing and interpretation approaches. The subsurface structure configuration trending in E–W, N–S, NW–SE, NE–SW, ENE–WSW, and NNE–SSW directions has been simulated by utilizing aerogravity and aeromagnetic data. According to these maps, the study area is divided by around 44 faults. The study's findings indicated that the direction of the basement structure was almost NE–SW and N–S. The optimum Euler depth deconvolution at structure index, SI = 0 shows several features in the study area, including Sill, Dyke, Ribbon, and Step structures.
Self-Confidence and STEM Career Propensity: Lessons from an All-Girls Secondary School
Authors: Siani Alessandro , Harris Jasmine
Published: March 2023

Gendered barriers in education and attrition along the academic and professional pipeline are key determinants of the current STEM skills shortage. While enrolment in STEM undergraduate courses has been increasing in the recent decades, STEM degree choices still suffer from considerable gender imbalance, whereby women are underrepresented in maths-heavy subjects and overrepresented in biological and healthcare subjects. This study sought to investigate the relationship between maths/science self-confidence and propensity towards STEM careers during secondary education, a critical period in the university course decision-making process. Non-parametric analysis of cross-sectional survey data collected in an English all-girls secondary school revealed an overall decline in self-confidence over the 5 years of secondary education, which was statistically significant for science, but not maths. Self-confidence in maths showed a strong positive correlation with students’ propensity towards careers in maths and science, but not in technology/engineering. Likewise, self-confidence in science was positively correlated with maths and science propensity, but had no effect on technology/engineering propensity. These findings indicate that the teaching of maths and science is by itself not sufficient to promote engagement with STEM career pathways in engineering and technology. Secondary curricula should explicitly emphasise the links between the learning of mathematical and scientific concepts, their practical applications, and the career opportunities they enable.
On the Journey Through Ukraine: Representations of the Holocaust in Friedrich Gorenstein’s Traveling Companions
Authors: Ronell Anna P.
Published: March 2023

For about three decades now, there has been an ongoing shift towards Geocritical literary analysis so that reading literature historically is now often supplemented by reading literature geographically, foregrounding the most significant political and natural features of the landscape (borders; big cities; shtetlach; mountains; valleys; rivers; forests), as well as the “mindset” of the population and the major historical events associated with them. Friedrich Gorenstein’s novel Traveling Companions (1989) is devoted most explicitly and holistically to the Holocaust in Ukraine and the dynamics of its spatial representation. Gorenstein also writes in a palimpsest mode: he simultaneously works with multiple layers of memory, not all of it his own, inscribed onto particularly Jewish spaces imbued with dense layers of historical events, ideational developments, and living experiences. The concepts of literary territoriality and the treatment of place, space, flow, and movement in literature and culture, including the interplay between the geographies of the ‘real’ and the geographies of the ‘imaginary’ are critical for the understanding of temporal-spatial displacements employed by Gorenstein as he attempts to reconstruct and interpret the textual map of the Holocaust in Ukraine. Gorenstein’s writing grapples with the complex relationship between the geographical space of Ukraine and the memory of the Holocaust and exposes his readers to the permutations of Jewish history and geography while focusing on the concepts of uprootedness, homelessness, and alienation as well as mass murder and irredeemable evil.
Post-LOCA control room dose analysis for Maanshan NPP using the AST methodology
Authors: Wang Cheng-Der
Published: March 2023

To address the issue identified in USNRC’s Generic Letter (GL) 2003-01 that the unfiltered air in-leakage rate through plant’s control room envelope during design basis accident may exceed that assumed in the licensing analysis and thus threat the control room habitability, the control room envelope unfiltered in-leakage Tracer Gas Test (TGT) for Maanshan nuclear power plant (NPP) has been performed in 2020. For future applications, an improved control room dose analysis approach using Alternative Source Terms (AST) has been developed in present study to check whether the TGT results meet regulatory limits and have sufficient safety margins. The AST method follows Regulatory Guide 1.183 (RG 1.183) and the TGT results must be fulfilled the total effective dose criteria set forth in 10 CFR 50.67. Based on the AST approach and the TGT results, the control room personnel dose for Maanshan NPP during Loss of Coolant Accident (LOCA) is 14.35 mSv, and the safety margin is 71.3%. It is sufficient to cover the effects of structural ageing and changes in meteorological data during the control room habitability reassessment and the analysis uncertainty.
Welche Bücher Teichmüllers lagen Nietzsche vor? Versuch einer Rekonstruktion
Authors: Schwenke Heiner
Published: March 2023

Which Books by Teichmüller Did Nietzsche Have Access to? An Attempt at a Reconstruction. The question of which books by Gustav Teichmüller Nietzsche had available has not been satisfactorily clarified to this day. Drawing on sources not considered so far, including the correspondence between Teichmüller and Franz Overbeck and a list that Teichmüller kept about copies of his writings he had sent to colleagues and friends found in his Nachlass, I conclude that Nietzsche only had four books by Teichmüller at his disposal (apart from the opusculum Ueber die Reihenfolge der platonischen Dialoge). Three of these were loans: Aristotelische Forschungen I from the University Library of Basel in the summer semester of 1870, Die
Wirkliche und die scheinbare Welt, from Overbeck between late summer 1882 (at the earliest) and November 1885, and the Neue Studien zur Geschichte der Begriffe III also from Overbeck from October 1883 to November 1885. Only the Aristotelischen Forschungen II seem to have been Nietzsche’s personal property (since 1869). Although it is often assumed that Nietzsche also read other books by Teichmüller – e. g., the Studien zur Geschichte der Begriffe, the Neue Studien zur Geschichte der Begriffe II, and the two volumes of the Literarische Fehden im vierten Jahrhundert v. Chr. – they were most likely not available to Nietzsche.

Authors: Gürçal Erkan , Erdoğu Burçin , Çevik Özlem
Published: March 2023

This article examines the complex social organization that emerged in the mid-6th Millennium BC from the perspective of new research conducted in Uğurlu (Phase III), on the island of Gökçeada (Imbros). The mid-6th Millennium BC witnessed major cultural transformations and abrupt changes in virtually all regions from Anatolia to Central Europe, as new settlements brought new forms of social organization. Our aim here is to stimulate further debate about the early complex social organization in the mid-6th Millennium BC. The results of this study reveal a well-organized rural community on the island, reflected in the complex settlement layout, with ritual areas, multifunctional central buildings and activity areas.

A Case Investigation into Causes of Premature Rutting Failures in Rehabilitated Asphalt Pavements in Tanzania
Authors: Anochie-Boateng Joseph K. , Malisa John T.
Published: March 2023

Tanzania has faced high incidences of premature rutting failures on their asphalt pavements. Some pavements experienced failures within one to two years after construction/rehabilitation. The objective of this investigation was to identify the factors that contributed to the observed failures on five rehabilitated road sections on a national highway in Tanzania. Pavement temperature data collection, traffic surveys, visual inspection, rut depth measurements, and falling weight deflectometer tests constituted the main activities of the field investigation reported in this paper. The laboratory study included a visual assessment of cores extracted from the studied road sections to determine both physical and engineering properties, including density, stiffness, strength, aggregate shape properties, grading, and physiochemical tests on the recovered binders. The results of the study indicated that the degree and extent of rutting on the investigated road sections was rated as severe., i.e., rutting ranged from 38–138 mm on the five sections when compared to the acceptable threshold value of 15 mm for high volume roads in Tanzania. The elastic deflection results indicated that the underlying layers of the pavement system were generally in a sound condition, which validated the suggestion that the rutting observed was mostly confined to the asphalt concrete layers. Factors such as relatively high axle loads, poor asphalt mixes, and possibly inadequate quality control during construction and rehabilitation were suspected to contribute to the rutting on the sections. Practical measures recommended to the roads agency to avert future occurrences are provided in this paper.
Effect of Sintering Temperature on the Structural, Dielectric, and Magnetic Properties of Garnet-Spinel Ferrite Composites for Use in L-Band Devices

Published: March 2023

Herein we have reported the influence of sintering temperature on the structural, dielectric, and magnetic properties of garnet ferrite composite. The composite of gadolinium iron garnet and magnesium ferrite (Gd3Fe5O12[x]/MgFe2O4[1−x] at x = 0.75) was synthesized by the mechanical blending method and then sintered at 900°C and 1,300°C. X-ray diffraction study suggests that both of the phases of ferrites are present in the composites without any impurities. Field emission scanning electron microscopy images indicate the change in microstructure with sintering temperature. Dielectric study reveals that the sample sintered at 900°C has a higher value of dielectric constant (ε′r). The grain and grain boundary contributions in the composites have been elucidated by fitting the Nyquist plot with an electrical equivalent circuit. The extracted grain boundary resistance was found to increase from 64.7 MΩ to 2 × 1018 MΩ, and grain resistance has been decreased to 1.78 × 10−22 Ω from 293.5 Ω with an increase in temperature. From the magnetic hysteresis loop we have calculated the anisotropy constant (Keff) = 770, anisotropy field (Ha) = 168.5 Oe, squareness ratio (SQR) = 0.07, and microwave operating frequency (ωm) = 2 GHz for the sample sintered at 1,300 °C. These parameter values suggest the potential use of these composites for microwave devices operating in the L band.
Blue light promotes zero‐valent sulfur production in a deep‐sea bacterium
Authors: Cai Ruining , He Wanying , Zhang Jing , Liu Rui , Yin Ziyu , Zhang Xin , Sun Chaomin
Published: March 2023

Increasing evidence has shown that light exists in a diverse range of deep‐sea environments. We unexpectedly found that blue light is necessary to produce excess zero‐valent sulfur (ZVS) in Erythrobacter flavus 21‐3, a bacterium that has been recently isolated from a deep‐sea cold seep. E. flavus 21‐3 is able to convert thiosulfate to ZVS using a novel thiosulfate oxidation pathway comprising a thiosulfate dehydrogenase (TsdA) and a thiosulfohydrolase (SoxB). Using proteomic, bacterial two‐hybrid and heterologous expression assays, we found that the light–oxygen–voltage histidine kinase LOV‐1477 responds to blue light and activates the diguanylate cyclase DGC‐2902 to produce c‐di‐GMP. Subsequently, the PilZ domain‐containing protein mPilZ‐1753 binds to c‐di‐GMP and activates TsdA through direct interaction. Finally, Raman spectroscopy and gene knockout results verified that TsdA and two SoxB homologs cooperate to regulate ZVS production. As ZVS is an energy source for E. flavus 21‐3, we propose that deep‐sea blue light provides E. flavus 21‐3 with a selective advantage in the cold seep, suggesting a previously unappreciated relationship between light‐sensing pathways and sulfur metabolism in a deep‐sea microorganism.
Stanowisko posłów podlaskich w sprawie unii polsko-litewskiej na sejmie brzeskim w 1566 r.
Authors:   Łomżyńskie Towarzystwo Naukowe im. Wagów, Kalinowski Emil
Published: March 2023

The article contains an edition of the historical source from 1566 connected with old Polish parliamentarism, so far barely known in historiography, with comprehensive periphrasis of its historical background and its content. It contains a joint position of six envoys elected at the sejmiks of Podlasie to the Sejm of Brześć-on-the-Bug in 1566, expressed on behalf of the nobility remaining in their homes, on the issue of the union of the Grand Duchy of Lithuania with the Kingdom of Poland. The research was based on the broadest possible source base, which included both materials published in print in the 19th, 20th and 21st centuries, as well as archival ones, including the preserved files of castle offices from Podlasie: in Drohiczyn, Mielnik and Brańsk and excerpts from them by Ignacy Kapica. The biographies of the authors of the writing are also presented: Adam Kosiński and Jan Buyno from Drohiczyn Land, Kasper Irzykowicz and Piotr Padkowski from Mielnik Land, Tomasz Owsiany and Wojciech Wyszkowski from Bielsk Land. They were prominent representatives of the local noble elite, almost all of them associated with the judiciary, which in Podlasie was based on Polish law. The source presented here is an interesting draft in many respects, showing the moods and aspirations of the Podlasian nobility several years before the memorable events of 1569: the incorporation of its voivodeship into Poland and the conclusion of the Polish-Lithuanian real union. Placing it in the context of existing knowledge and new findings about the then political situation in Podlasie completes this picture.
Ku ustanowieniu sądu ultimae instantiae. Laudum sejmiku województwa podlaskiego z 1577 r.
Authors:   Uniwersytet w Białymstoku, Urwanowicz Jerzy
Published: March 2023

Presented in a historical context, the document of 1577 reflects the last phase of the nobility’s drive to establish a supreme court. Previously, the court was the prerogative of the king, who examined cases from across the state during the sessions of the diet. This was inefficient. The ever-increasing backlog of pending appeals caused dissatisfaction among the nobility. Disputes and discussions revolved around its form (central authority – the Tribunal, or a decentralized form – ultimae instantiae courts), its composition and method of selecting judges, as well as its scope of authority. The Podlasie province, newly incorporated (in 1569) into the Polish Crown, participated in the process, uniting its forces with the Sandomierz and Lublin provinces at the forefront of the battle for the court of appeal. The decentralized form of the court, described in the document, was treated as a temporary institution. Also, it was intended as a way to put pressure on the king and the parliament to establish a central court of appeal. In the course of these activities, the nobility of Podlasie led to the consolidation of the fourth assembly (Polish: sejmik), a provincial one (in addition to the existing three assemblies (Polish: sejmiki ziemskie,). The 1578 Sejm resolution on the establishment of the Crown Court met the claims of the nobility of the Podlasie province (as well as from other provinces) stated in the document. The supreme court was established. At the same time, this decision led to the stabilization of the operation of the assembly of Podlasie. Its main function was the annual election of judges to the Tribunal. The resolution is a testimony to the political maturity and high standards of legal decorum of the Podlasie nobility.
O Józefie Kantym Ossolińskim, winie i burzliwym przebiegu sejmiku przedkonwokacyjnego w Łucku zimą 1764 r.
Authors:   Uniwersytet Opolski, Ciesielski Tomasz
Published: March 2023

The article attempts to assess the influence of magnates on the course of sejmiks in the Polish-Lithuanian Commonwealth through the lens of the actions taken by Volyn voivode Józef Kanty Ossolinski in late 1763 and early 1764 to push through decisions favorable to the party of the so-called republicans at the pre-convocation sejmik in Lutsk. Despite very intensive efforts and a great deal of material generosity, including the importation of several thousand liters of wine, these efforts failed due to the equally good preparation of political opponents – the ‘family’ led by the Crown huntsman Stanisław Czartoryski, supported by several other magnates, as well as the court militia and the Czartoryski rented nobility, who managed to dominate the sejm. Although Ossoliński managed to unite the republican camp, he failed to prevent first a brawl and profanation of the church, and then a division of the sejm into two circles sitting separately. At both instances’, deputies to the Convocation Sejm and extraordinary, so called “kapturowy” judges were elected, which meant that the struggle for political domination of Volhynia continued for another three months. In the end, it was the deputies appointed by the Czartoryskis who were declared legitimately elected, although it should be noted that three of them did not come to the convocation for political reasons. The article is based on hitherto under-utilized source material from the resources of archives and academic libraries in Poland and abroad, which has been critically evaluated using research methods characteristic of the discipline of history.
Profesor Stanisław Płaza – badacz sejmików. O Mistrzu
Authors:   Wyższa Szkoła Humanitas w Sosnowcu, Lityński Adam
Published: March 2023

Stanisław Płaza (1927–2006) is a leading figure among scholars writing about local noble parliamentary assemblies. Stanisław Płaza created a synthesis of our knowledge about Crown local noble parliamentary assemblies. The author introduces the reader to the figure of the scholar, his life. Before Płaza finished school he found himself (in 1940) with his whole family in a Soviet Gulag, like many Poles, as a result of the Soviet occupation of over half of Poland after the Hitler-Stalin pact of 1939. After the war he returned to Poland, completed his studies and became a researcher at the Jagiellonian University. He obtained the title of professor. Stanisław Płaza placed the local noble parliamentary assembly in an original way in the whole complicated system of state and self-government bodies. Stanisław Płaza put in order our ideas and our knowledge about the system of the former Republic of Poland, and especially about the parliamentary system, fundamental in the system of noble democracy. The author himself wrote a lot about the local noble parliamentary assemblies of the former Republic of Poland, and was a friend and collaborator of Professor Stanisław Płaza. In spite of the high recognition of Professor Stanisław Płaza’s mastery, the author often argued with him academically. Currently, the author recalls the scientific achievements of Professor Stanisław Płaza and old polemics, which were closely observed in scholarly circles.

The sejmik (dietine) records of the Old Polish period are an invaluable source material concerning almost all aspects of the everyday life of that time. In the Małopolska (Little Poland) province, apart from the general sejmik sporadically held in Nowe Miasto Korczyn and occasional assemblies of the nobility from some lands and districts, there were 17 regular sejmiks. The paper first discusses all the editions of sejmik resolutions that have so far appeared in print. The study then presents the next volumes of this kind of source texts that are under preparation for publication. When describing the process of editing sejmik records, attention was drawn to the research centers that have made contributions to this research field, and to individual historians involved in such undertakings. The text also stresses the changes that took place in the first decades of the 20th century, when publishers took into account various categories of sources concerning the functioning of Old Polish sejmiks. A lot of room is devoted to the scope of library and archival research and to major stores of source materials that were and still are used by editors. The paper closes with a list of all existing and planned publications that are expected to appear in this field in the coming years.
Preparation of gold nanoparticles on nanocellulose and their catalytic activity for reduction of NO2-
Authors: Guo Zihe , Fu Shiyu
Published: March 2023

Nanoscale material has attracted the interest of many researchers because of its special physicochemical and surface properties. In this study, a nanocomposite was prepared based on cellulose nanocrystals (CNCs) in situ forming ultra-fine size gold nanoparticles. To form the gold nanoparticles, chloroauric acid was reduced with an aqueous mixture of ethanol and CNC. The gold nanoparticles were less than 8 nm in size, with 80% of them less than 5 nm. Nanocellulose in the preparation system acted as a stabilizer. The size and dispersity of the ultra-fine gold nanoparticles (UAuNPs) were controlled by adjusting the pH. The resulting UAuNPs/CNCs composite exhibited excellent catalytic performance to eliminate solubilized NaNO2 mixed with NH4Cl at room temperature. The apparent rate constant of the reaction was 4.12 × 10-5 s-1. The catalytic effect of the generated UAuNPs on NO2- reduction has potential use in many fields, particularly in the food and environmental sectors.

Published: March 2023

Refining is a primary unit operation that has a large impact on the quality of paper products and cost of production. The refining process of cellulose fibers is the most energy-intensive step in the preparation of paper pulp. High energy consumption during the refining process has motivated researchers to improve the economics of the process without decreasing the strength of the paper produced. This objective can be realized through easily refined pulps that are produced from alternative vegetal fibrous raw materials. This work compares the energy consumption of refining soft, hardwood, and fast-growing fibrous materials to 30 °SR. The goal was to reduce energy consumption while maintaining the strength properties of the paper received. For this purpose, cellulose pulps from fast growing plants including poplar, larch, and grasses were used.

Authors: Dąbrowski Mariusz , Górski Jarosław
Published: March 2023

Mobile shields at woodworking machine workstations were considered in this work as part of a protection and accident prevention system. A shield design based on an aluminium frame is proposed. The results of the experimental tests demonstrated the high efficiency of material kick attenuation using the mobile shields, irrespective of their position and the filling used. Operational tests on the mobile shields were performed in a woodworking shop, which confirmed their usefulness and made it possible to supplement the conclusions with interesting observations concerning their dimensional and visual features, among other things.
Impact of pulp drying modes for water-retention values measured by headspace gas chromatographic method
Authors: Wang Ruoyun , Li Yaping , Mo Wen-Xuan
Published: March 2023

The water-retaining capabilities of bleached chemical pulps treated by the oven-, air-, vacuum-, and freeze-drying modes were determined with use of a reliable the headspace gas chromatographic method (HS-GC) developed recently. The results showed that reliable water retention data could be determined by the HS-GC method only in the case of air-dried pulp. This result was supplemented by observations of the surface morphology of the fibers from these drying processes. The present HS-GC method can be used for checking the differences of wettability (at a given equilibration time) of pulp specimens from different drying modes.

Gambir is one of the most economically important natural products of Indonesia. Indonesia accounts for 80% of the global exports of this product. The product contains catechin, a phenolic compound of the flavonoid group, which has demonstrated bioactivity against horticulture-destroying fungi. However, its bioactivity in controlling wood-decaying fungi has not yet been reported. A laboratory study was conducted to examine the characteristics of the catechin of gambir and its bioactivity against the wood-decaying fungi Schizophylum commune Fr. Extraction of catechin from gambir was conducted via a gradual maceration process using hot water (70 °C, 3 h) followed by ethyl acetate (1:10 w/v, 4 h). The chemical components of catechin were analyzed by gas chromatography mass spectrometry (GCMS), while its bioactivity against S. commune was examined according to EN 113 (1986). The results showed that there were five chemical components in catechins, i.e., 1,2-benzenediol, catechol, 1,3,5-benzenetriol, dimethyl terephphtalate, and terephthalic acid. These compounds demonstrated the ability to remarkably inhibit the growth of S. commune.

Foams are encountered in everyday life across wide applications, e.g., in foods and cleaning products. They have also been widely used in different industries in processes such as flotation and oil recovery. The application of bio-based materials is a novel interest, and foam forming enables these materials to be used more flexibly. For efficient industrial usage, the flow of such materials must be well understood and characterized. This work measured the velocity field of nanocellulose laden foam in a two-dimensional Hele-Shaw cell with a constriction, using optical imaging and particle image velocimetry. The measurements showed that the addition of cellulose increased the effective viscosity of the liquid films. In a numerical simulation using the Giesekus polymer model, the experimental trend was reproduced through increasing the fluid’s viscosity. Adding highly viscoelastic nanofibrillated cellulose suspension to foam affected only the viscous component of the foam. The delayed elastic response did not change.

Published: March 2023

Lignocellulose nanofibrils (LCNFs) were prepared using Liriodendron tulipifera L. wood flour. Electrospun nanofibers were fabricated by mixing the LCNFs with poly(vinyl alcohol) (PVOH). The lignin and hemicellulose contents of the wood flour were controlled with an alkaline-peroxide treatment at a pH of 11.5 using various hydrogen peroxide concentrations. The morphological characteristics, mean diameter, and filtration time of the LCNFs subjected to wet disk milling (WDM) and high-pressure homogenization were determined. Furthermore, the spinning suspension viscosity was measured with various LCNF concentrations and PVOH/LCNF addition ratios. After the alkaline-peroxide treatment, the lignin and hemicellulose contents decreased with an increasing hydrogen peroxide concentration and reaction time. As the lignin content decreased, the nanofibril diameter decreased and the filtration time increased. The diameter decreased further after the homogenization treatment following WDM. The viscosity of the mixed solution increased with an increasing PVOH and LCNF mixed solution concentration and LCNF addition ratio, and decreasing lignin content. Scanning electron micrographs revealed that the diameter of the electrospun nanofibers increased as the mixed solution concentration and LCNFs addition increased, the lignin content decreased, and with the homogenization treatment.

As a purified form of cellulosic fiber, dissolving pulp is an important starting material for many value-added cellulose products. Dissolving pulp is mainly produced by either the pre-hydrolysis kraft (PHK) process or the acid sulfite (AS) process. The dissolving pulp market has been booming in many developing countries in recent years. As one of the biggest producers of dissolving pulp in the world, China is also importing a large amount of dissolving pulp from other countries. It is expected that the production capacity of dissolving pulp in China will increase significantly in the near future.

Published: March 2023

Rubber tree and oil palm are industrial crops cultivated in the same climate and environment. These plants are used to prepare nanocomposites of natural rubber and cellulose from empty fruit bunches, an abundant residue in the palm oil industry. For this study, the cellulose particles were extracted from the bunches and subjected to enzymatic hydrolysis or microfibrillation to produce nanostructured particles. The nanoparticles were blended with natural rubber latex in an aqueous medium, and the mixture was dried. The properties of the nanocomposites were compared to those of pure natural rubber and unprocessed cellulose composites. The mechanical properties of the natural rubber can be modified by the cellulose content and morphology. As a consequence, it is possible to modulate the material properties by changing only the filler morphology. The use of microfibrillated cellulose had stronger reinforcement effects. The thermal properties of natural rubber were not affected by the addition of cellulose.
