Investigation of Roller Bearing Cage Pocket Lubrication and Friction
Authors: Peterson Wyatt , Sadeghi Farshid , Meinel Andreas , Grillenberger Hannes 
Published: January 2023

Abstract
A test rig was designed and developed to assess the lubrication and friction of a single cylindrical roller and a conformal cage pocket. The roller was lubricated via oil bath in a sealed housing. Inner and outer bearing raceway pieces were fixed above and below the roller to mimic the internal geometry of an actual bearing. The cage pocket was made from transparent acrylic to look inside the cage and observe oil flow during operation. A six-axis load cell was used to measure the torque generated by the entire test rig with and without the cage pocket and used to isolate the friction of the cage pocket. Experiments were conducted to investigate the effects of roller–pocket clearance, roller–raceway clearance, and roller oil submersion level at rest. Results suggest that roller bearing cage pocket friction increases with decreasing pocket clearance, increasing oil availability, and increasing operating speed. The oil was observed to coalesce into stable striations inside the cage pocket for many operating conditions. Striation width was observed to decrease with increasing speed, increasing pocket clearance, and decreasing oil availability. The striations were summarized by oil volume fraction inside the cage pocket, which decreased with increasing speed, decreasing pocket clearance, and decreasing oil availability. The current results provide new information about oil behavior inside roller bearing cage pockets during operation, and an approach is presented to estimate roller bearing cage pocket friction.

AbstractMetatarsal fractures represent the most common traumatic foot injury; however, metatarsal fracture thresholds remain poorly characterized, which affects performance targets for protective footwear. This experimental study investigated impact energies, forces, and deformations to characterize metatarsal fracture risk for simulated in situ workplace impact loading. A drop tower setup conforming to ASTM specifications for testing impact resistance of metatarsal protective footwear applied a target impact load (22–55 J) to 10 cadaveric feet. Prior to impact, each foot was axially loaded through the tibia with a specimen-specific bodyweight load to replicate a natural weight-bearing stance. Successive iterations of impact tests were performed until a fracture was observed with X-ray imaging. Descriptive statistics were computed for force, deformation, and impact energy. Correlational analysis was conducted on donor age, BMI, deformation, force, and impact energy. A survival analysis was used to generate injury risk curves (IRC) using impact energy and force. All 10 specimens fractured with the second metatarsal being the most common fracture location. The mean peak energy, force, and deformation during fracture were 46.6 J, 4640 N, 28.9 mm, respectively. Survival analyses revealed a 50% fracture probability was associated with 35.8 J and 3562 N of impact. Foot deformation was not significantly correlated (p = 0.47) with impact force, thus deformation is not recommended to predict metatarsal fracture risk. The results from this study can be used to improve test standards for metatarsal protection, provide performance targets for protective footwear developers, and demonstrate a methodological framework for future metatarsal fracture research.

Published: January 2023

AbstractParticipants in American football experience repetitive head impacts that induce negative changes in neurocognitive function over the course of a single season. This study aimed to quantify the transfer function connecting the force input to the measured output acceleration of the helmet system to provide a comparison of the impact attenuation of various modern American football helmets. Impact mitigation varied considerably between helmet models and with location for each helmet model. The current data indicate that helmet mass is a key variable driving force attenuation, however flexible helmet shells, helmet shell cutouts, and more compliant padding can improve energy absorption.
Understanding Frugal Engineering for Equity: Exploring Convergence of Biological Designs and Social Innovations
Authors: Malshe Ajay P. , Bapat Salil , Fischer Lukas 
Published: January 2023

Abstract
Multiple global trends and drivers have resulted in a steep escalation of tech-socio-economic inequities in basic human needs across industrialized as well as industrializing nations. This escalation is paralleled by the growing trend of novel and simple frugal innovations for meeting basic human needs, which are applied across various communities in the world towards bridging gaps of inequity. Frugality in this context is defined as minimizing the use of capital resources while delivering effective manufacturing product outcomes. It is noteworthy that frugal innovations are abundantly observed in the biological designs in nature. This paper is aimed at understanding the methodology of frugal engineering behind the resulting frugal manufacturing innovations through discovering the cross-section of frameworks of biological designs in nature and equitable social innovations. Authors have applied the framework of biological designs as these designs are observed to deliver multifunctionality, resilience, and sustainability, which are key to a frugal and equitable innovation platform and achieved by the frugal engineering process. As water is one of the most basic human needs, this paper uses water as an illustrative example to understand the frugal engineering process. The authors discuss designs in nature from cactus, tree roots, and human skin, and design parallels in related frugal innovations namely in fog-capturing nets, ice stupa, and Zeer (pot-in-a-pot), respectively, for equitable water access. The authors propose and discuss a resulting methodology for frugal engineering. This methodology can be utilized as a starting point for developing case-specific socially conscious manufacturing solutions.
Design and Development of the Transmission for a Fully Actuated 5-Degrees-of-Freedom Compliant Robot Manipulator With a Single Motor
Authors: Pisetskiy Sergey , Kermani Mehrdad R. 
Published: January 2023

AbstractThis article presents a novel architecture for the actuation and transmission system of a 5-degrees-of-freedom (DOFs) compliant robot manipulator. The compliant behavior of the robot is achieved using inherently compliant magneto-rheological (MR) clutches introduced in antagonistic pairs in every joint of the manipulator. All five antagonistic MR clutch pairs are driven using a single brushless DC motor located in the base of the robot. The MR clutch pairs are coupled to the motor through a system of shafts, belts, and gears. Several possible architectures for realizing a suitable drive train are presented, and the advantages and disadvantages of each concept are analyzed. The most efficient architecture for the drive train is selected to complete the design of the manipulator. The kinematics of the manipulator using the adopted architecture is further analyzed, and the workspace of the system is presented. To the best of our knowledge, this is the first 5-DOF, fully actuated, compliant robotic manipulator that uses a single DC motor to achieve five independent axes of rotations.

Published: January 2023

Abstract
With the continuous development of internal combustion engine technology, the thermal efficiency of traditional energy vehicles has been difficult to improve, and the heat loss caused by high-temperature exhaust emissions is an important reason for the low thermal efficiency. To utilize the exhaust heat, the aim is to develop various spiral tube heat exchanger designs, namely, constant curvature heat exchanger with baffle and variable curvature heat exchanger. The design has been evaluated by referring to the performance evaluation coefficient (PEC); furthermore, the convection coefficient h has been taken into consideration as well. The idea is to perform numerical studies via computational fluid dynamics package and evaluate the performance of the spiral tube heat exchanger designs. PEC is the relationship between the heat exchange intensity of the heat exchanger and the flow resistance of the working fluid. The results show that the PEC evaluation index of the heat exchanger is the best when the spiral diameter of the heat exchange tube is 120 mm, and with the increase of the tube diameter and pitch, the overall performance of the heat exchanger decreases. The research on heat transfer enhancement of heat exchangers was carried out, and various spiral tube heat exchangers were designed based on the structure of spiral heat exchange tubes. The variable curvature heat exchanger has better overall performance than the baffle constant curvature heat exchanger. Compared to the single-variable curvature and the double-variable curvature, the maximum PEC difference of them does not exceed 0.01, and the double-variable curvature is more sufficient in volume utilization, and it can save about 13% volume. Considering the use requirements of the actual vehicle waste heat recovery system, the double-variable curvature spiral tube heat exchanger is more suitable for practical engineering applications than the single-variable curvature spiral tube heat exchanger.

Published: January 2023

Parvovirus B19 (B19V) infects human erythroid progenitor cells (EPCs) and causes several hematological disorders and fetal hydrops. Amino acid (aa) 5–68 of minor capsid protein VP1 (VP1u
5–68aa
) is the minimal receptor binding domain for B19V to enter EPCs. Here, we carried out a genome-wide CRISPR-Cas9 guide RNA screen and identified tyrosine protein kinase receptor UFO (AXL) as a proteinaceous receptor for B19V infection of EPCs.
AXL
gene silencing in ex vivo expanded EPCs remarkably decreased B19V internalization and replication. Additions of the recombinant AXL extracellular domain or a polyclonal antibody against it upon infection efficiently inhibited B19V infection of ex vivo expanded EPCs. Moreover, B19V VP1u interacted with the recombinant AXL extracellular domain in vitro at a relatively high affinity (

= 103 nM). Collectively, we provide evidence that AXL is a co-receptor for B19V infection of EPCs.

ObjectiveGrowing evidence indicates that tumour cells exhibit characteristics similar to their lineage progenitor cells. We found that S100 calcium binding protein A10 (S100A10) exhibited an expression pattern similar to that of liver progenitor genes. However, the role of S100A10 in hepatocellular carcinoma (HCC) progression is unclear. Furthermore, extracellular vesicles (EVs) are critical mediators of tumourigenesis and metastasis, but the extracellular functions of S100A10, particularly those related to EVs (EV-S100A10), are unknown.DesignThe functions and mechanisms of S100A10 and EV-S100A10 in HCC progression were investigated in vitro and in vivo. Neutralising antibody (NA) to S100A10 was used to evaluate the significance of EV-S100A10.ResultsFunctionally, S100A10 promoted HCC initiation, self-renewal, chemoresistance and metastasis in vitro and in vivo. Of significance, we found that S100A10 was secreted by HCC cells into EVs both in vitro and in the plasma of patients with HCC. S100A10-enriched EVs enhanced the stemness and metastatic ability of HCC cells, upregulated epidermal growth factor receptor (EGFR), AKT and ERK signalling, and promoted epithelial–mesenchymal transition. EV-S100A10 also functioned as a chemoattractant in HCC cell motility. Of significance, S100A10 governed the protein cargos in EVs and mediated the binding of MMP2, fibronectin and EGF to EV membranes through physical binding with integrin αⅤ. Importantly, blockage of EV-S100A10 with S100A10-NA significantly abrogated these enhancing effects.ConclusionAltogether, our results uncovered that S100A10 promotes HCC progression significantly via its transfer in EVs and regulating the protein cargoes of EVs. EV-S100A10 may be a potential therapeutic target and biomarker for HCC progression.

“Idźcież już precz!” [Come on, get out already!]: The Origins and Development of the Earliest Anti-Jesuit Literature in the Commonwealth of Poland–Lithuania, 1577–1614
Authors: Maryks Robert Aleksander 
Published: January 2023

Abstract
This article is the first account in English of the origins and development of the earliest anti-Jesuit literature in the Commonwealth of Poland–Lithuania from the publication in 1577 of the first anti-Jesuit work, Jakub Niemojewski’s (c.1532–84) Diatribe abo kolacyja przyjacielska z ks. Jezuitami poznańskimi o przedniejsze różnice wiary krzescijańskiej (Diatribe or a friendly supper with Poznań Jesuit fathers about the main differences of the Christian faith), until the publication in 1614 of the most famous and most influential anti-Jesuit work not only in Poland but also in other parts of Europe, the Monita privata [secreta] (Private [hidden] instructions) ascribed to the Polish (ex-)Jesuit, Hieronim Zahorowski (c.1582–1634). The essay places the Polish anti-Jesuit literature, written mostly in Latin but also in Polish, within its broader context of such literature in western Europe, of which it was an integral part, for the texts from both younger and older Europe influenced each other and borrowed from each other. (Younger Europe refers here to the Scandinavian–Baltic–Slavic–Hungarian–Balkan part of the continent that was Christianized some centuries after Older Europe). Such a presentation aims at showing the indisputable importance of anti-Jesuit literature for the culture and politics not only of the early modern and but also of the modern history of Europe, including Poland, whose contours were shaped by the Jesuits, for better or worse, to a degree exceeding that of all other Catholic religious organizations. Several topoi examined here fed into anti-Jesuit conspiracy theories, which constitute one of the core themes of this special issue of the jjs. These conspiracy theories gave legitimacy to the aim of expelling the Jesuits, who were portrayed as forming a secretive society that had invaded Poland–Lithuania to fulfill the agenda of foreign powers through deception and assassination.
The Deceivers Deceived: How a Seventeenth-Century Venetian Anti-Jesuit Circle Duped a Jesuit Rector
Authors: Pavone Sabina 
Published: January 2023

Abstract
In 1608, Antonio Barisone (1557/8–1623), rector of the Jesuit college at Ferrara, became ensnared in an elaborate deception designed to expose the unscrupulous methods by which Jesuits exploited vulnerable wealthy widows and enlarged the material wealth of their Society. Entering into a correspondence with a Venetian noblewoman who lamented the loss of her Jesuit confessor following the expulsion of the Society of Jesus from Venice (1606), it took several months before Barisone realized that the letters he was receiving actually had their origins in the anti-Jesuit circles linked to Paolo Sarpi (1552–1623). In addition to throwing light on Venice as a hotbed of espionage, political rumors, and conspiratorial activity in the early sixteenth century, this episode foregrounds several themes and leitmotifs that would go on to dominate anti-Jesuit polemic over the subsequent centuries.
Conspiracy Theory as a Vehicle for a Jesuit-Free Portugal under the Pombaline Government (1750–77)
Authors: Franco José Eduardo , Carreira Paula 
Published: January 2023

Abstract
During the reign of José I (1714–77), his prime minister, the marquis of Pombal paired an expansive program of Enlightenment reform with a dramatic anti-Jesuit policy whose impact extended far beyond Portugal. The Pombaline anti-Jesuit measures, accompanied by intensive international propaganda, were the end result of negative evaluations of the role played by the Jesuits in Portugal. A diabolical causality made the Society of Jesus responsible for the degeneration of the church, the corruption of politics, the backwardness of education, and the laxity in morals. This essay focuses on two aspects of Pombal’s campaign: first, the use of the church structures against a part of the church (the Society of Jesus); secondly, the identification of a philosophical authority, namely Aristotle, as supplying the intellectual underpinnings of the Jesuit order and symbolizing the allegedly outmoded forms of instruction associated with Jesuit pedagogy
“A picture is worth a thousand words”: Visual Media and the Anti-Jesuit Conspiracy Theory in the Age of Enlightenment
Authors: Vogel Christine 
Published: January 2023

Abstract
In the context of news reporting about anti-Jesuit government actions and within the media landscape of eighteenth-century Europe, anti-Jesuitism began to posit a comprehensive superconspiracy and, in doing so, interweave religious and political aspects. Visual media played a decisive role in this process. Due to their high degree of intermediality and frequent recourse to allegory, printed news images were able to bundle ongoing debates and condense complex arguments. The allegorical pictorial language of these images was a specifically baroque form of non-linear “hypertextuality” that went far beyond the linear patterns of causality normally associated with the verbal and textual cultures of the Enlightenment. The visual dimension of news reporting was a means of cross-referencing and connecting that, by defying linear logic, promoted the idea that “nothing is as it seems” and that “everything is connected.”
“A sinister creature is on the loose”: Anti-Jesuit Conspiracy Allegations as Political and Poetological Strategies in the First Half of the Nineteenth Century in Tyrol
Authors: Oberhauser Claus 
Published: January 2023

Abstract
The restoration of the Jesuits in Tyrol in 1838/39 shocked the region’s liberals and this shock found expression in the medium of poetry as exemplified by the polemical “Jesuitenlieder” (Jesuit songs) that circulated throughout Tyrol and southern Germany. A few years later a debate developed in German newspapers about the influence of the Jesuits in Tyrol. While older, but also more recent studies often only focused on the literary quality and the liberal elements of the debate, the affinity of this discourse for the tropes of the conspiracy theory has been overlooked until now. Ultimately, the appeal of invoking such tropes was the possibility it afforded of branding the so-called “Jesuitism” and, in doing so, covertly criticizing the government.
The Provincial Chinese and the Progress of Iloilo Textile in Nineteenth-Century Philippines
Authors: Madrid Randy M. 
Published: January 2023

Abstract
This paper examines the role of provincial Chinese in the progress of Iloilo textile in nineteenth century Philippines. It argues that the provincial Chinese played a pivotal role in Iloilo’s urban morphogenesis, which is contrary to the prevailing view that Iloilo’s progress has been spurred only by Western global enterprise, especially with the emergence of the sugar trade primarily operated by the British. The facets of Iloilo’s pre-colonial and colonial trade, specifically the textile business run by the Chinese, served as tour de force that brought about internal transformations in the local economy prior to European trade expansions in the overseas colonies in the second half of the nineteenth century. This study falls under the domain of urban history but with special emphasis on the interplay of material culture with that of the political economy of port cities in Asia during the nineteenth century. Its research framework has been drawn from advocates of microhistory. The framework employs privileging first-hand accounts and primary sources to explore historical experiences of a particular sector of the society (provincial Chinese), tracking clues through multiple sources to unearth hidden connections (provincial Chinese and urban progress), reconstructing webs of social networks (provincial Chinese with Ilonggos, Spaniards and other Europeans), and scaling analysis to highlight specific historical contexts or perspectives provincial Chinese and the textile trade). Many of the information in the study has been gathered through extensive library and archival research, especially nineteenth century records and documents of Iloilo Chinese found in the National Archives of the Philippines (nap) and other libraries and archives in the country. Data analysis has been undertaken through clustered themes and sub-themes that revolved around textile trade and the participation of provincial Chinese on it.
