The coronavirus disease 2019 (COVID-19) pandemic in nursing homes – the experience of care workers in Poland
Authors: Necel Ryszard 
Published: March 2023

Background: Nursing homes in Poland are the most common formal care institutions for dependent people. During the coronavirus disease 2019 (COVID-19) pandemic, nursing homes had particularly high infection rates. In this context, it is important to ask about the experiences of the care workers working in these institutions. Methods: This research was conducted using the computer-assisted web interviewing (CAWI) technique in five provinces in Poland. The field research was carried out in April 2021. The research sample included, among others, nurses, care workers, therapists, social workers and the management staff of institutions whose representatives worked during the COVID-19 pandemic. Respondents were asked to assess the care provided to residents. Results: It turned out that the vast majority of respondents positively assessed the fulfillment of the basic living needs of residents and the availability of care. The assessment of the organization of residents’ leisure time, the fulfillment of their religious and cultural needs, and the issue of maintaining contacts with the social environment was less satisfactory. The article also describes the results of care institution employees’ self-assessment of their mental health. For the majority, the most stressful factor was the need to work in a health-threatening environment and the sense of responsibility for the residents. Regarding the availability of the forms of support offered to workers experiencing deteriorating mental health due to working in the pandemic situation, more than a third said that their institution did not offer any form of assistance. Conclusions: The article lists a number of recommendations. In the light of the data obtained, it is necessary to increase the intensity of services provided to residents of nursing homes in terms of organizing their free time, meeting their religious and cultural needs and maintaining contact with the social environment.

In recent years, there has been a growing interest in the measurements
of the bidirectional reflectance distribution function (BRDF) in
industry and research and development. However, there is currently no
dedicated key comparison to demonstrate the scale conformity. To date,
scale conformity has been proved only for classical in-plane
geometries, in comparisons between different national metrology
institutes (NMIs) and designated institutes (DIs). This study aims at
expanding that with nonclassical geometries, including, for the first
time, to the best of our knowledge, two out-of-plane geometries. A
total of four NMIs and two DIs participated in a scale comparison of
the BRDF measurements of three achromatic samples at 550 nm in five
measurement geometries. The realization of the scale of BRDF is a
well-understood procedure, as explained in this paper, but the
comparison of the measured values presents slight inconsistencies in
some geometries, most likely due to the underestimation of measurement
uncertainties. This underestimation was revealed and indirectly
quantified using the Mandel–Paule method, which provides the
interlaboratory uncertainty. The results from the presented comparison
allow the present state of the BRDF scale realization to be evaluated,
not only for classical in-plane geometries, but also for out-of-plane
geometries.
Parents’ differential susceptibility to a “micro” parenting intervention: Rationale and study protocol for a randomized controlled microtrial
Authors: Chhangur Rabia R. , Belsky Jay 
Published: March 2023

Background
Given evidence that parenting can influence children’s development, parenting interventions are often the strategy of choice when it comes to treating children’s disruptive behavior problems—or preventing problems from developing in the first place. What remains under appreciated, however, is that some parents appear to be more responsive to interventions to foster skilled parenting than others. Notable in this regard is the ever-increasing observational and, perhaps more importantly, experimental evidence indicating that some children prove more susceptible to parenting interventions than others. So, while the experimental evidence clearly indicates that “susceptibility factors” which children carry seem to affect their likelihood of benefiting from a parenting intervention (and other environmental influences), what remains unclear is why the parenting interventions in question prove more effective in changing the behavior of some parents more than others. Could it be as a result of their own parental characteristics?

Objective
The Parfective Microtrial in a randomized controlled microtrial, in which we focus not just on parental (and child) responsiveness but also on an underlying physiological mechanism hypothesized to contribute to heightened susceptibility to parenting interventions.

Methods
Participants are 120 families, with children aged 4–5 years, recruited from the community. Of these, 60 are randomly assigned to the “micro” intervention condition (i.e., immediate positive parenting feedback) and 60 families to the care-as-usual control condition. Assessments in both conditions will be conducted at baseline (pretest), after 2 weeks (posttest), and after 4 weeks (follow-up). Primary outcomes are the hypothesized moderating effects of physiology on the anticipated “micro” intervention effect (i.e., decrease in negative parenting behavior and/or increase in positive parenting behavior). Secondary outcomes are the observed (changes in) child behavior in response to the parenting intervention, such that those parents and children—in the same family—who manifest these physiological attributes will prove most susceptible to the beneficial effects of the intervention.

Trial registration
This study protocol is registered at ClinicalTrials.gov (NCT05539170).

Glucagon and exenatide improve contractile recovery following ischaemia/reperfusion in the isolated perfused rat heart

Published: March 2023

AbstractThe 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.

AbstractMechanosensitive 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.

Abstract
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

Abstract
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

Abstract
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

Abstract
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

Abstract

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.

Abstract
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

Abstract
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.

Abstract
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

Published: March 2023

AbstractIncreasing 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.
