Published: December 2021

The paper presents the effect of gas dosing parameters on the microporous structure of physically foamed polyamide 66 reinforced with 30 wt% of glass fibers (PA66 + 30% GF). The thick-walled molding was used as the research object. To realize the research aim, simulation software was applied. The variable parameter in a research program was a dose of supercritical fluid, in this case, nitrogen. The tested properties of a cellular structure were: cell size, cell density and local density of a material. All the parameters were considered based on 30 measurement points evenly distributed in the central zone of the sample’s cross-sectional area. The largest size of pores was observed in the core region of molding for every amount of supercritical (SCF) fluid used. It was shown that regardless of the amount of gas, the pore size increases as a function of the distance from the mold cavity surface until it achieves a constant value. However, the most rapid increase was observed in the case of the smallest amount of gas dosed (0.25 wt%) which also resulted in the largest pore size in the core zone of a molding. The lowest value of cell density was noticed for 0.25 wt% of gas used. In the case of 0.5 wt%, 0.75 wt% and 1 wt% of gas dosed, results of cell size, as well as cell density, were comparable. However, dosing 1 wt% of gas resulted in obtaining the finest structure, characterized by the smallest pore size and highest cell density. As a parameter resulting from a cell size and cell density, the local density of material was analyzed. The lowest value of local density in the core area was noticed for 0.25 wt% of SCF dosed.

Authors: Malinowska Małgorzata , Muślewski Łukasz
Published: December 2021

Vegetable oils are considered to be an alternative and environmentally friendly resource of lubricants. Suitable for almost all industrial applications. They are obtained from natural raw materials, which are renewable and non-toxic to humans, living organisms, and the environment. Chemically, green oils are triacylglycerols with varying fatty acids compositions depending on the plant or seed, the crop, the growing conditions and the season, etc. The conducted research concerning matching the proper of type of vegetable oil to lubrication of the engine. The main objectives of engine oil have been drawn to the attention. To project of assessment has selected four roles of engine oil: lubrication, cooling, corrosion protection, and others (including oxidative stability, ash content, saponification value, and foam property). Each objective is described by a couple of detailed parameters of lubricants (for example viscosity index, coefficient of friction, wear scar diameter, pour point, cloud point, melting point, smoke point, flash point, iodine value, thermal conductivity, specific heat capacity, density, water content, acid number, anti-corrosion properties, etc.). In the evaluation process, AHP (Analytic Hierarchy Process) methods were used to determine the weights of individual criteria. Everything creates multiple criteria assessment of green oil. As a result of the multi-criteria assessment, most high scores have soybean oil, linseed oil, cottonseed oil, and olive.

Authors: Dykha Aleksandr , Matiukh Serhii , Łukasiewicz Marcin , Dluhunovych Natalia
Published: December 2021

The study of the properties of consistent and liquid oils is currently receiving much attention in tribology. This is because lubrication is one of the most effective ways to improve machine durability. At the same time are practically no mathematical descriptions of the mechanisms of grease lubrication, which is necessary for predicting and calculating the wear of machines. When studying the wear of surfaces under boundary lubrication conditions, it is necessary to know the stiffness characteristics of a thin layer of lubricant under normal and tangential stresses. In this paper, a method is proposed for determining the function of the contact tangential characteristics of a thin oil layer between solid deformable surfaces. A thin layer of grease is placed between two hard discs. By measuring the angle of rotation and the moment on the second disc, the dependence of the moment on the angle of rotation is determined. The contact mechanics of torsion of a thin circular lubricant layer has been developed and relations for determining the parameters of the shear diagram of a thin lubricant layer have been obtained. According to the developed method, the Fiol-3 grease was tested and the parameters of the shear diagram were determined.
Diagnostics, measurement and control of electrical parameters supercapacitors
Authors: Boiko Juliy , Kałaczyński Tomasz
Published: December 2021

This article considers possible approaches to diagnostics and measurement electrical parameters of supercapacitors. The analysis the results of diagnostics and measurement the parameters of supercapacitors has determined a significant frequency dependence of theirs. The discrepancy between the two-element equivalent circuit of supercapacitors has been established. Diagnostics and control electrical parameters of supercapacitors in the infralow frequency range can be performed by direct conversion methods. In this case, high-precision low-resistance resistors can be used as an exemplary measure. For the diagnostics and design of meters for the electrical parameters of supercapacitors of capacitors, the authors propose an iterative-recursive method for determining the numerical values of the electrical parameters of the equivalent circuit of such objects. The essence of the proposed iterative-recursive method is that at the first stage, the iterative approximation determines the number of n-absorption links, which it is enough to know when developing, manufacturing and operating supercapacitors. Theoretical and experimental studies of the equivalent circuit of supercapacitors show that the equivalent resistance of such capacitors and their capacitance increase with decreasing frequency of the measuring signal, and the nature of these dependences is determined by the number of n-absorption links and the numerical values of the elements of each link.

Liebeskummer
Authors: Walter Henrik
Published: December 2021

Liebeskummer, die emotionale Reaktion auf romantische Zurückweisung, ist ein normaler Bestandteil des Lebens und wird üblicherweise nicht als psychische Erkrankung verstanden. Dennoch kann er zu viel Leid führen und ist ein wichtiger Risikofaktor für Suizid bei Jugendlichen und im jungen Erwachsenenalter. In diesem Artikel wird der Liebeskummer genauer unter die psychiatrische Lupe genommen. Dabei werden seine Psychologie, Neurobiologie und Therapie dargestellt, die Frage gestellt, ob er mehr als eine Anpassungsstörung sein kann und sein soziologischer Kontext und seine Zukunft untersucht. Dem Liebeskummer, so das Fazit, sollte in Psychiatrie und Psychotherapie mehr Aufmerksamkeit geschenkt werden. Zudem kann er der psychiatrischen Forschung als Modell dienen, um Aspekte stressbezogener Erkrankungen wie Anpassungsstörungen, anhaltende Trauer, posttraumatische Belastungsstörungen, Depressionen und Sucht besser untersuchen und verstehen zu können.

Rape myths in practice: the everyday work of accounting for rape survivors
Authors: Brooker Phillip , Butler Catherine
Published: December 2021

‘Rape mythologising’ has been found to be a reason why survivors of rape feel blamed, and might contribute to low rates of reporting or conviction. No research to date examines whether ‘rape mythologising’ occurs in the conversations of sexual health staff when discussing rape cases. Conversation Analysis was used to analyse a focus group conversation between five sexual healthcare clinic staff who routinely provided support to rape survivors, on the topic of three rape cases presented at the clinic. Three forms of conversation were noted in the focus group: (1) assessing ‘relatability’ in cases, (2) diagnostically reconstructing events and (3) apportioning blame to rapists. Implications for professional training are discussed. In all three, a tension was noted between drawing on rape myths and professional non-blaming discourses. This research demonstrates the need for further training of those who work with rape survivors.
The influence of transformational leadership and teachers’ trust in principals on teachers’ working commitment
Authors: Mansor Azlin Norhaini , Abdullah Rosnita , Jamaludin Khairul Azhar
Published: December 2021

The responsibilities of teachers and principals in Government Funded Religious Schools (GFRS) in Malaysia have become more demanding as the enrolment rates have risen over time. The principals’ transformational leadership (TL) potentially affects teachers’ trust (TT), which directly influences their work commitment (WC) in school. However, limited evidence is available to support this assertion. Thus, this study seeks to investigate: (a) the level of TL, TT, and WC and (b) the influence of TT as a mediator between TL and WC from the teachers’ perspective in the Government Funded Religious Schools (GFRS) in Selangor. This study employed a survey research design. A survey questionnaire was administered to 297 GFRS teachers in Selangor. These teachers were selected using a stratified random sampling technique. Descriptive (means, standard deviation, frequency, and percentage) and inferential statistics (analysis of regression and predictive accuracy) were employed to analyse the data. The findings suggested that the overall level TL (M = 4.077, SD = 0.533), TT (M = 4.070, SD = 0.521) and WC (M = 4.188, SD = 0.413) in GFRS in Selangor were ‘high’. It was also found that TL was a significant predictor of TT (B = 0.867, SE = 0.026, p < 0.05) and WC (B = 0.361, SE = 0.083, p < 0.05), with approximately 29% of the variance in WC accounted for by TL (R2 = 0.290). However, TT was not a significant predictor of WC (B = 0.064, SE = 0.085, p > 0.05), suggesting that TT did not mediate the relationship between TL and WC. Even though this study exemplified that the level of TL, TT and WC was at a high level, TT was found to have an insignificant effect on WC. This provides a new insight in understanding this complex relationship. The dynamic of relationships—among teachers, between teachers and staff, and with outside parties, might have an impact on developing TT and WC among these teachers.
Process expertise in policy advice: Designing collaboration in collaboration
Authors: Molinengo Giulia , Stasiak Dorota , Freeth Rebecca
Published: December 2021

Complex societal and environmental challenges motivate scholars to assume new roles that transcend the boundaries of traditional academic expertise. The present article focuses on the specialised knowledge, skills, and practices mobilised in the context of science–policy interfaces by researchers who advise policymakers on collaborative governance processes intended to address these pressing issues. By working on the backstage of collaborative arrangements, researchers support policymakers in the co-design of tailor-made strategies for involving groups of institutional and non-institutional actors in collaboration on a specific issue. The present article examines the expertise underpinning this practice, which we termprocess expertise. While already quite widely practiced, process expertise has not yet been comprehensively theorised. The study employs a self-reflective case narrative to illuminate its constitutive elements and investigates the advisory work of the authors’ research team, called “Co-Creation and Contemporary Policy Advice”, located at the intersection of science, policymaking, and civil society. The findings show that process expertise, when exercised by researchers and supported by an assemblage of enabling conditions inherent to the research context, goes beyond the possession of a set of skills at the individual level. Instead, process expertise in the context of science–policy interfaces unfolds in interaction with other types of knowledge and fulfils its task by generating a weakly institutionalised “in-between space”, in which researchers and policymakers interact to find more inclusive ways of tackling complex challenges. In this realm, relational work contributes to establishing a collaborative modus operandi at the very outset of the advisory process, while working at the processual level supports knowledge co-production among multiple actors. The article argues that it is the ongoing work of process experts at the intersection of relational and processual levels that helps maintain momentum in these collaborative partnerships. By formulating and discussing five constitutive elements of process expertise, this paper untangles the complex work that is required in collaborative research settings and gives a language to the invisible work performed by researchers who offer policymakers—and other invited actors—advice on theprocessof designing collaborationincollaboration.

Field of study decisions are important for children’s future life chances, as significant differences exist in terms of financial and status benefits across fields of study. We examine whether the economic or the cultural status of the parents is more influential in shaping their children’s expectations about their future field of study. We also test whether children’s expectations about field of study choices are mediated by the child-rearing values that parents hold. Results show that parental economic status increased the likelihood of adolescents expecting to opt for extrinsic rewarding fields of study. Adolescent girls, not boys, with high cultural status parents were more likely to expect to opt for intrinsically rewarding fields of study. An upbringing that is characterized by conformity increased the expectations of boys to choose an extrinsically rewarding study, while self-direction increased the expectations of girls to opt for an extrinsic field of study

There has been growing interest in the use of the sol-gel approach to form high-quality dielectric materials. Their tailored properties allow for developing functional electronic devices in a scalable and rapid manner. According to physicochemical principles, the displacement and response behavior of charges under an applied external field can manifest in unique dielectric properties, providing useful information to improve the process, design, and quality of electronic devices. Therefore, a systematic and in-depth investigation of the fundamentals of sol-gel dielectrics is necessary. In this Research Update, we present recent advances in various sol-gel-processed dielectric materials and their applications to functional electronic devices. A brief introduction to sol-gel chemistry to form oxide dielectric films and the basis of physical mechanisms under electrical fields are discussed. Along with the dielectric properties, recent achievements of proof-of-concept experiments and their various applications to functional electronic devices are introduced. It is expected that further innovations in solution-processed metal oxide dielectrics will achieve cost-effective high-performance functional electronics in the near future.

Optical networks generate a vast amount of diagnostic, control, and performance monitoring data. When information is extracted from these data, reconfigurable network elements and reconfigurable transceivers allow the network to adapt not only to changes in the physical infrastructure but also to changing traffic conditions. Machine learning is emerging as a disruptive technology for extracting useful information from these raw data to enable enhanced planning, monitoring, and dynamic control. We provide a survey of the recent literature and highlight numerous promising avenues for machine learning applied to optical networks, including explainable machine learning, digital twins, and approaches in which we embed our knowledge into machine learning such as physics-informed machine learning for the physical layer and graph-based machine learning for the networking layer.
Quality of Evidence and Legal Decision-Making

We analyze a setting where the court has to impose liability with imperfect evidence on the defendant’s actions, and where the court is concerned about both deterrence and judicial errors. We provide a formal definition of the quality of evidence that allows us to compare evidence from very different sources and of a very different nature in terms of informativeness. When imposing liability, the court’s optimal policy is to set an evidentiary standard. The main result of the article is that with a higher quality of evidence, more lenient evidentiary standards generate greater welfare. We also find that when the agent can influence the informativeness of the evidence the interests of court and agent are not aligned. The optimal court policy may involve penalizing (even forbidding) actions leading to less informative evidence.
On Dissonance and Its Functions in Asian American Criticism
Authors: Cruz Denise
Published: December 2021

Building upon recent work in Asian and Asian American studies, this essay explores dissonance, rather than disinterestedness, and its function and form for literary studies in our present time. It is inspired not only by my rereading of Matthew Arnold’s essay but also the convergence of key events over the course of the last few years, ranging from recent attention to Asian and Asian American cultural production to anti-Asian hate crimes. As an Asian Americanist, I research and teach in a field whose very emergence was tied to activist claims for institutional and disciplinary space. I therefore find it profoundly difficult to imagine our endeavors in American literary studies as “disinterested.” I am less invested in making the case whether or not the study of Asian American literature “matters”; rather, here I explore why Asian American literary studies—a method that seeks out and dwells in dissonance and urgency rather than disinterestedness and patience—might be a model worth continuing.
Membranous nephropathy associated with immunoglobulin G4-related disease successfully treated with obinutuzumab

Immunoglobulin G4 (IgG4)-releated disease is typically associated with interstitial nephritis, but rare cases of idiopathic membranous nephropathy as a renal manifestation have been described. Obinutuzumab was successfully used in refractory membranous nephropathy, but evidence for the treatment of IgG4-related disease with obinutuzumab is lacking. We report one patient's case with membranous nephropathy associated with IgG4-related disease who was treated with obinutuzumab following an anaphylactic reaction to rituximab. Obinutuzumab treatment resulted in a sustained complete remission of membranous nephropathy and a decrease of IgG4 to the normal range. This case demonstrates that membranous nephropathy associated with IgG4-related disease can be treated successfully with obinutuzumab.
Dizziness in an avid cyclist: an unusual presentation of a common problem

Background

Presyncope and syncope are common presentations with a wide range of differential diagnoses; when it occurs primarily on exertion, a cardiovascular cause is more likely. Structural abnormalities and primary rhythm disturbances are the usual culprits in these patients.

Case summary

A 75-year-old gentleman presented with a history of progressive exertional presyncope. His investigations demonstrated normal cardiac structure, function, and rhythm. He underwent an exercise stress test, which demonstrated a significant reduction in peak blood pressure with equivocal electrocardiogram changes and absence of ischaemic symptoms. In view of his age and gender, a computerized tomography coronary angiogram (CTCA) was organized to exclude obstructive coronary artery disease (CAD). Intriguingly, the CTCA demonstrated a severe proximal left anterior descending (LAD) artery stenosis. This stenosis was confirmed to be functionally significant using invasive coronary physiology and was treated with percutaneous coronary intervention. At follow-up, there was no recurrence of exertional presyncope and the patient was continuing to return to his baseline function.

Conclusion

Presyncope and/or syncope as the sole manifestation of obstructive CAD, in the presence of normal ventricular function and valves, has rarely been reported. Myocardial ischaemia-mediated presyncope and/or syncope may be secondary to numerous mechanisms, which are described in this case report. Revascularization of the functionally significant proximal LAD stenosis resulted in cessation of exertional presyncope in our patient. The long-term outcome of revascularization in patients with presyncope and syncope needs to be further investigated.
Restating US Foreign Relations Law: Lessons from the Treaty Materials
Authors: Bradley Curtis A , Swaine Edward T
Published: December 2021

This short article responds to observations made by Alina Miron and Paolo Palchetti about the treaty sections of the Restatement of the Law (Fourth): The Foreign Relations Law of the United States. We describe the nature of the Restatement process and explain why the choices made in the Restatement (Fourth) were more constrained than what might be suggested by Miron and Palchetti’s critique. We also engage with some of their specific observations about the Restatement (Fourth)’s approach to treaties, resisting the suggestion that the approach marks a retreat from engagement with international law.
On The Robustness Of Respondent-Driven Sampling Estimators To Measurement Error
Authors: Fellows Ian E
Published: December 2021

Respondent-driven sampling (RDS) is a popular method of conducting surveys in hard to reach populations where strong assumptions are required in order to make valid statistical inferences. In this paper we investigate the assumption that network degrees are measured accurately by the RDS survey and find that there is likely significant measurement error present in typical studies. We prove that most RDS estimators remain consistent under an imperfect measurement model with little to no added bias, though the variance of the estimators does increase.
