Published: August 2022

Background
As a country’s future leaders and pioneers, University students must live with healthy habits. In order to achieve a healthy lifestyle, Physical activity and Quality of Life can serve as suitable indices to study. The purpose of the study was to clarify how physical activity (PA), Body mass index (BMI) and gender relate to the quality of life (QOL) of students of Medical Sciences University by using a structural equation model.

Methods
The research was a cross-sectional study. The number of participants was 225 students of the University. The participants answered three questionnaires, including Demographic, International Physical Activity Questionnaire (IPAQ short form), and Quality of Life Questionnaire (SF-12), BMI was calculated by anthropometric measures, as well. The Structural equation model (SEM) method was employed. The Fitness of the proposed pattern was measured using the following indexes: chi-square/degree of freedom ratio (CMIN/DF), Normed Fit Index (NFI), comparative fit index (CFI), the goodness of fit index (GFI), and standardized root mean squared residual (SRMR). In the analysis the significant level was considered as P < 0.05.

Results
PA (r = -0.726, P<0.001) and QOL (r = -0.405, P<0.001) have significantly inverse relationship with BMI, whereas the QOL and PA were proven to be positively related (r = 0.357, P<0.001). Moreover, the results signify gender as a moderator in the relationship between PA and QOL (Δχ2 (10) = 19.903, P = 0.030) and also the mediatory role of BMI among students. BMI affects the QOL in men (P < 0.001, β = -0.307) more in compare to women women (P = 0.324, β = -0.158).

Conclusion
Study findings supported the research hypothesis. Gender exhibited moderating role in the relationship between PA and QOL, considering the mediating role of BMI.

Published: August 2022

Background
Arterial cannulation in elderly patients is difficult because of age-related morphological changes. Applying dynamic needle tip positioning (DNTP) that guides the catheter to position inside the vessel sufficiently may aid in successful cannulation.

Methods
This prospective study enrolled patients aged over 70 years, who were scheduled for elective surgery under general anaesthesia with arterial cannulation. The patients were randomly assigned to the DNTP (group D, n = 76) or the conventional short-axis view(group C, n = 75) group. The arterial depth, diameter, and arterial conditions(calcification, segmental stenosis, and tortuosity) were evaluated using ultrasound, before puncture. We recorded the first attempt success, cannulation time, the number of attempts, and cannulation-related complications.

Results
A total of 151 patients were enrolled in this study. The first attempt success rate in group D was significantly higher than that in group C (89% versus 72%; P = 0.0168). The median cannulation time per last attempt in group D versus group C was 25 versus 30 sec(P = 0.0001), and the overall cannulation time was 25 versus 35 sec(P = 0.0001), respectively. Arterial cannulation per last attempt and overall cannulation time were shorter in group D. The number of attempts was higher in group C (P = 0.0038). The occurrence rate of hematoma was significantly lower in group D (16% versus 47%, relative risk = 3.0, P = 0.0001).

Conclusions
The DNTP method may improve the first attempt success rate of arterial cannulation and reduce complications in elderly patients over 70 years of age.

Published: August 2022

Abstract

Objectives
Study and management of a case with elevated potassium levels without apparent clinical causes in successive follow-up visits.

Case presentation
We present the case of a primary care female patient who persistently exhibited elevated levels of potassium (5.3–5.9 mmol/L) in successive control laboratory tests, without an apparent clinical cause. The patient was ultimately referred to the Unit of Nephrology, where a potassium-low diet was indicated. Diet did not have any effect on potassium levels. After a thorough study, the cause of hyperkalemia could not be determined.

Conclusions
The inconsistency between elevated potassium levels and the reason of consultation, and exclusion of other pre-analytical or pathological causes raised suspicion of familial pseudohyperkalemia. The sample was incubated at different times and temperatures to demonstrate their influence on levels of potassium in blood. Familial pseudohyperkalemia was established as the most probable diagnosis. Finally, the patient was discharged from the Unit of Nephrology and instructed to follow a normal diet.
Stability of combination of rarefaction waves with viscous contact wave for compressible Navier-Stokes equations with temperature-dependent transport coefficients and large data
Authors: Dong Wenchao , Guo Zhenhua 
Published: August 2022

Abstract
In this article, we study the large-time behavior of combination of the rarefaction waves with viscous contact wave for a one-dimensional compressible Navier-Stokes system whose transport coefficients depend on the temperature. It is shown that if the adiabatic exponent γ is suitably close to 1, the unique solution global in time to ideal polytropic gas exists and asymptotically tends toward the combination of a viscous contact wave with rarefaction waves under large initial perturbation. New and subtle analysis is developed to overcome difficulties due to the smallness of γ – 1 to derive heat kernel estimates. Moreover, our results extend the studies in a previous work [F. M. Huang, J. Li, and A. Matsumura, Arch. Ration. Mech. Anal. 197 (2010), no. 1, 89–116].
Minimal hypersurfaces in manifolds of Ricci curvature bounded below
Authors: Ding Qi 
Published: August 2022

AbstractIn this paper, we study the angle estimate of distance functions from minimal hypersurfaces in manifolds of Ricci curvature bounded from below using Colding’s method in [T. H. Colding, Ricci curvature and volume convergence, Ann. of Math. (2) 145 1997, 3, 477–501]. With Cheeger–Colding theory, we obtain the Laplacian comparison for limits of distance functions from minimal hypersurfaces in the version of Ricci limit space. As an application, if a sequence of minimal hypersurfaces converges to a metric coneC⁢Y×ℝn-k{CY\times\mathbb{R}^{n-k}}(2≤k≤n{2\leq k\leq n}) in a non-collapsing metric coneC⁢X×ℝn-k{CX\times\mathbb{R}^{n-k}}obtained from ambient manifolds of almost nonnegative Ricci curvature, then we can prove a Frankel property for the cross sectionYofCY. Namely,Yhas only one connected component inX.

Why do zombie firms seldom die or resurrect? The effect of government subsidies on the survival duration of China’s zombie firms
Authors: Deng Ming , Wang Jinbo 
Published: August 2022

Abstract
One of the most important tasks in China’s supply-side structural reform is to effectively clean up zombie firms. Using industrial firm-level data in China from 1998 to 2007, we identified zombie firms in Chinese industrial sectors. Based on the identified zombie firms, we measured the survival duration of zombie firms and empirically studied the effect of fiscal subsidies on the survival duration of zombie firms by using survival analysis. Results revealed that fiscal subsidies significantly lengthened the survival duration of zombie firms. Specifically, fiscal subsidies not only reduced the possibility of zombie firms exiting the market, but more importantly, they reduced the possibility of zombie firms’ resurrection. Thus, fiscal subsidies do not contribute to the “death” or “resurrection” of zombie firms. These results are robust despite changing the identification method and the survival analysis method, and considering the endogeneity of fiscal subsidies. Our findings show that we should adhere to market-oriented mechanism in disposing zombie firms and cut off the channels that government transfuses to zombie firms by fiscal subsidies.
Chromizing of Additively Manufactured Maraging Steel; Microstructural Evolution and Corrosion Performance
Authors: Funch C. V. , Dahl K. V. , Christiansen T. L. , Somers M. A. J. 
Published: August 2022

AbstractWhile maraging steels are excellent candidates for additive manufacturing of high-strength materials, most of them provide little to no corrosion resistance. In this study, the surface of additively manufactured maraging steel is augmented with diffusion-based chromizing. The diffusion of chromium into the surface results in the formation of α-Cr, σ-phase and austenite depending on the chromium content at the respective distance from the surface. The bulk consists of a ductile bcc martensite hardened by precipitation of intermetallics during a low temperature ageing treatment. The σ-case provides a very high hardness, while the austenite phase is rather soft and unaffected by the ageing treatment. The chromizing treatment significantly reduced the corrosion rate of the maraging steel up to a factor of 14. Decomposition of the σ-case into a uniform case of austenite (austenitic stainless steel) further improved the corrosion resistance almost 24 times. This showed the strong potential of the chromizing treatment on a highstrength material to obtain a combination of their beneficial properties.
Customizing continuous chemistry and catalytic conversion for carbon–carbon cross-coupling with 3dP
Authors: McMillin Robert E. , Clark Brian , Kay Kaitlin , Gupton B. Frank , Ferri James K. 
Published: August 2022

Abstract
Support structures of various materials are used to enhance the performance of catalytic process chemistry. Typically, fixed bed supports contain regular channels enabling high throughput because of the low pressure drop that accompanies high flow rates. However, many fixed bed supports have a low surface-area-to-volume ratio resulting in poor contact between the substrates and catalyst. Three dimensional polymer printing (3dP) can be used to overcome these disadvantages by offering precise control over key design parameters of the fixed bed, including total bed surface area, as well as accommodating system integration features that are compatible with continuous flow chemistry. Additionally, 3dP allows for optimization of the catalytic process based on extrinsic constraints (e.g. operating pressure) and digital design features. These design parameters together with the physicochemical characterization and optimization of catalyst loading can be tuned to prepare customizable reactors based on objectives for substrate conversion and desired throughput. Using a Suzuki (carbon–carbon) cross-coupling reaction catalyzed by palladium, we demonstrate our integrated approach. We discuss key elements of our strategy including the rational design of hydrodynamics, immobilization of the heterogeneous catalyst, and substrate conversion. This hybrid digital-physical approach enables a range of pharmaceutical process chemistries spanning discovery to manufacturing scale.
Krimis, Crime und Pop-Kriminologie

Published: August 2022

KurzfassungDie Darstellungen in den Medien bestimmen das gesellschaftliche Bild von Kriminalität maßgeblich mit. Dabei geht es nicht allein um die Berichterstattung über reale Sachverhalte, sondern auch, und dies stellt den Fokus des vorliegenden Aufsatzes dar, um fiktive Formate. Anhand der aktuellen Studienlage wird diskutiert, inwieweit und wodurch diese in besonderem Maße gesellschaftliche (Fehl-)Vorstellungen prägen, welche Folgen dies auch für den tatsächlichen Umgang mit Kriminalität hat und welche besonderen Chancen sich ergeben, wenn kriminologische Themen und Erkenntnisse auch in Unterhaltungsformaten Beachtung finden.
Inquiry & Ordinary Truthmakers
Authors: Schipper Arthur 
Published: August 2022

AbstractThis paper argues that accepting an ordinary approach to truthmakers and rejecting something I call “the metaphysical knowledge assumption” (MKA) allows us to account for inquiry in terms of truthmaking. §1 introduces inquiry and the potential place of truthmakers in inquiry. §2 presents the relevant ordinary notion of truthmakers. §3 presents and motivates MKA. This assumption, I argue (§4), makes a truthmaker-focused account of inquiry whose objects are notthe fundamental nature of thingsimpossible and thus should be rejected. The ordinary picture, which understands truthmakers not exclusively in terms of the objects of fundamental reality or of semantics (§5), but in terms of the relevant, intentional objects of inquiry, gives us an attractive, general, truthmaker-based view of inquiry.

Deposition mechanisms and characteristics of nano-modified multimodal Cr3C2–NiCr coatings sprayed by HVOF
Authors: Shi Chenxi , Liu Shibin , Irfan  , Gong Qinglin , Wang Huan , Hu Ming 
Published: August 2022

Abstract
Nano-modified multimodal and conventional Cr3C2–NiCr coatings were fabricated by high-velocity oxygen-fuel spraying deposited on CuCrZr substrates. Results showed that individual nano-modified multimodal Cr3C2–NiCr particles were composed of nano (25−180 nm), submicron (200 nm to 0.5 μm), and micron (2–4.5 μm) Cr3C2 grains, NiCr binder phases, and a tiny amount of rare earth oxide additives. The nano-modified multimodal Cr3C2–NiCr coatings maintained a unique structure: submicron Cr3C2 grains embedded in the voids formed by micron Cr3C2 grains, NiCr binder phases and nano Cr3C2 grains imbedded in the voids formed by submicron and micron Cr3C2 grains, and nano Cr3C2 grains are dispersed in NiCr metal binder phases. A few discontinuous elongated amorphous and nanocrystalline phases existed in them. The mechanical interlocking was the dominant bonding mechanism accompanied by local metallurgical bonds. Compared to the conventional coating, the multimodal coating was uniform and dense (porosity was 0.3 ± 0.12%) as well as not obvious lamellar structures, the adhesive strength was 75.32 ± 1.21 MPa, exhibiting a 65 pct increase, and the microhardness was increased by about 18%. The lower porosity and higher strength of nano-modified multimodal structure coating were mainly related to dispersion distribution and synergistic coupling effects of Cr3C2 hard grains with different scales.
Indexicality and ideology in narratives about intimate partner violence
Authors: Andrus Jennifer 
Published: August 2022

Abstract
Theories of indexicality explain the ways in which linguistic forms are linked to social forms. As such, indexicality deals in part with ideology and cultural discourses. This article demonstrates the ways in which intimate partner violence (IPV), seen as an indexical, discursive formation, facilitates the material and social manifestations and ramifications of IPV. I argue for an expansion of the concept “indexical field” to account not only for phonemic variables, but also lexicosemantic variables. Such lexicosemantic variables are legible in narratives, in particular stories, that are circulated in and around IPV discourse. The indexical field forms a web of potential meanings for IPV. In the indexical field, variables have multiple potential and sometimes conflicting meanings, which can be and indeed are activated and made meaningful differently by different groups of speakers. My data are made up of 57 interviews, 34 with victims/survivors of IPV and 23 with police officers. The differences in indexical meaning surrounding IPV are analyzed from the perspective of critical discourse analysis. In this article, I show how victims/survivors of IPV animate variables in the IPV indexical field with meanings that conflict with the meanings attributed to the same words, phrases, and events by police officers. Because police officers have more institutional power, their indexical meanings often receive preference and coordinate with those of the society at large.
Fighting terrorism, fighting the West: Them versus Us appraisal in Chinese media’s discursive war on terror
Authors: Yu Hailing , Yue Jinhua , Yan Ye 
Published: August 2022

Abstract
While discourses on terror by the United States and its allies have been the focus of most previous studies, this article investigates discourses produced in the Chinese context. 247 news articles from China Daily and People’s Daily were analyzed according to a revised system of attitude within the appraisal framework in systemic functional linguistics (SFL). The findings reveal a correlation between polarity, types of attitude, and social actors being evaluated. Two Them groups, terrorism/terrorists in Xinjiang and Western media and governments, are overwhelmingly evaluated in terms of negative propriety of their behaviors and negative valuation of their things. Two Us groups, China and its people and non-Western countries supporting China, tend to be evaluated through positive valuation of their things, their positive capability, and positive and negative feelings (affect). The West is put in the same category as terrorism, quite contrary to what is commonly seen in the discourses produced by Western media. The attitudinal construction of Them and Us reflects not only the ideological square of negative other-presentation and positive self-presentation, but also the motivations of maintaining domestic stability and proper international relations behind China’s war on terror.

Abstract
Fleureau, A, Rabita, G, Leduc, C, Buchheit, M, and Lacome, M. Peak locomotor intensity in elite handball players: a first insight into player position differences and training practices. J Strength Cond Res 37(2): 432–438, 2023—The aims of the study were to (a) describe the peak locomotor intensity sustained during handball matches and (b) compare them with small-sided games (SSGs) programmed during training in elite handball players. Small-sided game (n = 342) and match (n = 121) data were collected among 11 players (25 ± 7 years, 191 ± 8 cm, 89 ± 12 kg) belonging to an elite French Handball team. Players' locomotor activity was recorded using 20-Hz Local Positioning System. Peak total (TD[m]) and high-speed running distance (HS[m]) and mechanical load (Accel’Rate [a.u.]) were calculated during different time periods (1–15 minutes different rolling averages). A plot of log (locomotor variables) against log (time) allowed to obtain a straight line with a slope and an intercept for each variable. Between-position differences during matches and difference between matches and SSGs were assessed with linear mixed model and magnitude-based decisions. Almost certainly higher peak locomotor intensity (intercept) was found in Wingers (TD: 156 ± 13; HS: 96 ± 12; Accel’Rate: 13 ± 3) compared with other playing positions for TD (Back players: 127 ± 10; Pivots: 136 ± 13), HS (Back players: 56 ± 9; Pivots: 57 ± 11), and Accel’Rate (Back players: 11 ± 2; Pivots: 11 ± 2). However, no clear between-position difference was found regarding the slope. Additionally, none of the SSGs format produced an overload in peak locomotor intensity in comparison with matches (TD: 138 ± 16; HS: 66 ± 20; Accel’Rate: 12 ± 2). Because reaching the peak locomotor intensity sustained during match is not possible using SSGs, practitioners should consider using isolated conditioning drills (e.g., short or long intervals, repeated sprints). Moreover, specific attention should be paid for Winger's work supplementation because they present the highest peak locomotor intensity in the team.
Recurring Cholinergic Inputs Induce Local Hippocampal Plasticity through Feedforward Disinhibition
Authors: Guerreiro Inês , Gu Zhenglin , Yakel Jerrel L. , Gutkin Boris S. 
Published: August 2022

AbstractThe CA1 pyramidal neurons are embedded in an intricate local circuitry that contains a variety of interneurons. The roles these interneurons play in the regulation of the excitatory synaptic plasticity remains largely understudied. Recent experiments showed that recurring cholinergic activation of α7 nACh receptors expressed in oriens-lacunosum-moleculare (OLMα2) interneurons can directly induce LTP in Schaffer collateral (SC)–CA1 synapses. Here, we pairin vitrostudies with biophysically based modeling to uncover the underlying mechanisms. According to our model, α7 nAChR activation increases OLM GABAergic activity. This results in the inhibition of the fast-spiking interneurons that provide feedforward inhibition onto CA1 pyramidal neurons. This disinhibition, paired with tightly timed SC stimulation, can induce potentiation at the excitatory synapses of CA1 pyramidal neurons. Our work details the role of cholinergic modulation in disinhibition-induced hippocampal plasticity. It relates the timing of cholinergic pairing found experimentally in previous studies with the timing between disinhibition and hippocampal stimulation necessary to induce potentiation and suggests the dynamics of the involved interneurons plays a crucial role in determining this timing.

Cilj. U ovome se radu daje pregled procesa obnove vrijedne knjižnične zbirke Instituta za povijest umjetnosti u Zagrebu uslijed preklapajućih kriza koje su obilježile 2020. godinu (potres, pandemija, poplava).
Pristup/metodologija. Cjelokupni fond Knjižnice trebalo je ispočetka sistematizirati prema UDK sustavu jer se u potpunosti urušio zbog snažnog potresa u ožujku. Taj se proces preklapao s postupkom primarne zaštite i konzervacije zbirke rukopisne građe osobnog arhivskog fonda Grge Gamulina, povjesničara umjetnosti i likovnog kritičara, te iznenadnom i hitnom potrebom osnivanja osobnog arhiva i ex libris zbirke akademika Tonka Maroevića.
Rezultati. Rezultat su tih simultanih procesa potpuno funkcionalan i resistematiziran knjižnični fond, uspostavljen arhiv i ex libris zbirka Tonka Maroevića te očišćena i organizirana zbirka rukopisnog gradiva Grge Gamulina.
Originalnost/vrijednost. Ovaj rad daje pregled aktivnosti i procesa pri postupanju s posebnim vrstama kulturne baštine u neočekivanim i izvanrednim okolnostima. Ti istovremeni procesi proširili su sve naše kapacitete te rezultirali stvaranjem novih modela suradnje među kolegama, posebice sa studentima i volonterima, te su dugoročno značajno utjecali na promišljanje i razvoj radnih procesa i snaga.
