Hydromagnetic effects on non-Newtonian Hiemenz flow
Authors: Sarkar Suman , Sahoo Bikash 
Published: September 2021

Abstract
The stagnation point flow of a non-Newtonian Reiner–Rivlin fluid has been studied in the presence of a uniform magnetic field. The technique of similarity transformation has been used to obtain the self-similar ordinary differential equations. In this paper, an attempt has been made to prove the existence and uniqueness of the solution of the resulting free boundary value problem. Monotonic behavior of the solution is discussed. The numerical results, shown through a table and graphs, elucidate that the flow is significantly affected by the non-Newtonian cross-viscous parameter L and the magnetic parameter M.
The Role of Bots in the Disinformation Process in Brazilian Politics between 2014 and 2018
Authors: Santana Célio , Nunes Amanda , Silva Fabio 
Published: September 2021

Abstract
This paper presents the participation of bots in the process of disinformation in the Brazilian political/electoral scenario between 2014 and 2018. The justification for this research was the growth of ideological polarization and the emergence of hate speech linked to political positioning that culminated in a massive campaign of disinformation, evidenced by fake news and other forms of manipulation. In this research multiple case studies were used referring to three moments: the 2014 elections, the 2016 impeachment and the 2018 election. We found studies investigating these events, and they were used as data sources for analysis of the conjuncture and the interpretation of these facts in a chronological perspective pointed toward the role of bots and the results of such actions. It has been observed that the use of bots has occurred since 2014; however, they were only engaged in propagating false content from 2015. The automation of the messages was sophisticated between 2014 and 2018, when bots ceased to be players who replicated posts indiscriminately (spam) to become users’ catalysts with the intention of creating or expanding new bubbles of disinformation. Finally, we observed that the same botnet active in Brazil was also involved in electoral processes around the world, making Brazil simply one more piece in this grand network of disinformation where who is involved and what their purpose might be is not known.
Sitting and talking together: packaging meaning into verbs with the neighbors
Authors: Mithun Marianne 
Published: September 2021

Abstract
As observed by Koptjevskaja-Tamm and Liljegren, the impact of language contact on grammatical typology is well recognized, but the field of lexico-semantic areal typology is still young. Here some mechanisms leading to an areal pattern are explored in the domain of certain sets of basic verbs in languages indigenous to the North American West. The patterns involve the apparent evocation, as part of the meanings of the common verbs, of certain features of the most immediately involved participant, particularly number, animacy, shape, and/or consistency. Two mechanisms apparently underlie the areal patterns. First, bilinguals accustomed to distinguishing such features lexically in verbs in one of their languages may simply choose more specific verbs in another language on a regular basis until, over time, original hyponyms come to be basic level terms. Second, shadows of compounding and derivation can be seen in some pairs of verbs in some languages. Patterns elsewhere in the language or in a neighbor can stimulate such formations and accelerate their lexicalization, ultimately blurring their internal structure and hastening their ascent to basic-level status.

Published: September 2021

Abstract
Primary aortic intimal sarcoma is a very rare disease and most patients present with features similar to those of atherosclerotic plaque and thrombus; however, primary aortic intimal sarcoma presents with features similar to those of intramural hematoma (IMH) on CT imaging and clinical presentation had never been previously reported. Here we report a case involving a 49-year-old woman with primary aortic intimal sarcoma masquerading as IMH on radiological images and clinical presentation. We also discuss some of the diagnostic pitfalls and hope that these diagnostic pitfalls will be very useful for clinicians.
Fabrication robustness in BIC metasurfaces

Published: September 2021

Abstract
All-dielectric metasurfaces supporting photonic bound states in the continuum (BICs) are an exciting toolkit for achieving resonances with ultranarrow linewidths. However, the transition from theory to experimental realization can significantly reduce the optical performance of BIC-based nanophotonic systems, severely limiting their application potential. Here, we introduce a combined numerical/experimental methodology for predicting how unavoidable tolerances in nanofabrication such as random geometrical variations affect the performance of different BIC metasurface designs. We compare several established all-dielectric BIC unit cell geometries with broken in-plane inversion symmetry including tilted ellipses, asymmetric double rods, and split rings. Significantly, even for low fabrication-induced geometrical changes, both the BIC resonance amplitude and its quality factor (Q-factor) are significantly reduced. We find that the all-dielectric ellipses maintain the highest Q-factors throughout the geometrical variation range, whereas the rod and split ring geometries fall off more quickly. The same behavior is confirmed experimentally, where geometrical variation values are derived from automated processing of sets of scanning electron microscopy (SEM) images. Our methodology provides crucial insights into the performance degradation of BIC metasurfaces when moving from simulations to fabricated samples and will enable the development of robust, high-Q, and easy to manufacture nanophotonic platforms for applications ranging from biomolecular sensing to higher harmonic generation.

Our case report discusses the efficiency of the histograms and flag warnings of the cell counter, indicating the importance of these variables.
Interaktion mit dem Fremden. Grenzen und Möglichkeiten der Tischgemeinschaft anhand von Daniel und Ester
Authors: Bühner Ruben A. 
Published: September 2021

Abstract
Most recent publications dealing with the question of table fellowship between Jews and gentiles in Early Judaism stake the assumption for granted that there is a common discourse behind the available sources. Thus, the relevant Jewish narratives (Dan, Est, Jdt, JosAs, Tob, Arist) are mutually used for explanation. In contrast, Ruben A. Bühner uses the Daniel and Ester narratives to exemplify that the texts present complex discourses that must be distinguished from one another and that testify to different lines of reasoning, which cannot be reduced to a uniform discourse.
The Core of the Sacrificial Calendar in Num 28–29 and Its Compositional History
Authors: Kislev Itamar 
Published: September 2021

Abstract
To date, scholarly examination of the developed legal section in Numbers 28–29 has taken place in the context of its relationship to the Lev 23 festival calendar and other pentateuchal calendars (Exod 23:14–19; 34:18–26; Deut 16:1–17) and its place in the formation of the Pentateuch. Independent analysis of this unit has the ability to illuminate this unit’s formation, probably the product of a long editorial process, enables isolation of the stage at which it was integrated in its current context, and reveals the purpose underlying its integration.
Scribal Experiences of Salvation – Aspects of Formation Processes in the Hezekiah-Isaiah Narratives
Authors: Panov Lida 
Published: September 2021

Abstract
To this day there is no consensus about the dating and literary growth of the Hezekiah-Isaiah narratives. This paper is a contribution designed to clarify the literary history of these stories. It considers processes of innerbiblical exegesis, aspects of a text-critical analysis and facets of their absolute and relative dating. Simultaneously, observations on the multiple cross connections with other texts reveal the theological substance of the stories: Experiences of misery that appear in the older Isaiah tradition developed into a salvation-theological ideal in the Hezekiah-Isaiah narratives.
Unusual cation coordination in nanostructured mullites

Published: September 2021

Abstract
Nanocrystalline mullite-type bismuth-bearing complex oxides Bi2(M0.5Al0.5)4O9 (M=Fe3+, Ga3+) are prepared by high-energy ball milling of the corresponding microcrystalline counterparts. An unusual five-fold coordination of metal cations is revealed in nanostructured Bi2(M0.5Al0.5)4O9 by means of 27Al magic angle spinning nuclear magnetic resonance and 57Fe Mössbauer spectroscopies. The concentration of five-fold coordinated cations increases with decreasing crystallite size of a material at the expense of octahedrally coordinated ones. In addition to the nuclear spectroscopic methods, Rietveld analyses of the X-ray diffraction data of the as-prepared nanooxides show that the constituent tetrahedra, octahedra, and the newly formed structural units with five-fold cation coordination are strongly distorted. With decreasing crystallite size of mullites, the average volume of their octahedra increases whereas this parameter decreases for tetrahedra. The macroscopic behaviour of the non-equilibrium nanomullites is characterised by SQUID magnetometry. The Fe-containing mullites exhibit a superposition of a dominant antiferromagnetism and a weak ferromagnetism. The increase in both the remanent magnetization and the coercive field with decreasing crystallite size is attributed to the effect of spin canting. The latter is confined to the interfacial and surface regions of the nanomaterials, and arises due to both the mechanically induced deformation of constituent structural units and the formation of cation sites with the unusual five-fold coordination.

Abstract
Nakamura, M, Sato, S, Kiyono, R, Yoshida, R, Yasaka, K, Yahata, K, and Konrad, A. Comparison between foam rolling with and without vibration on passive and active plantar flexor muscle properties. J Strength Cond Res 36(12): 3339–3344, 2022—Although foam rolling interventions with and without vibration have been used to increase flexibility in the field of sports, their effects on passive and active properties remain unclear. Hence, this study aimed to investigate the effects of foam rolling interventions on range of motion (ROM), shear elastic modulus, plantar flexor muscle strength, and jump performance. This randomized, controlled, crossover study included 16 healthy male subjects who visited the laboratory 3 times (control condition, foam rolling condition, and vibration foam rolling condition), each with an interval of >72 hours. In both foam rolling and vibration foam rolling conditions, subjects were instructed to perform 60-second bouts of intervention for 3 sets, with 30-second rest between each set. In the vibration foam rolling condition, the intensity of vibration was set at a frequency of 48 Hz. Dorsiflexion (DF) ROM, shear elastic modulus, plantar flexor muscle strength, and drop jump height were determined before and after the rolling intervention. Our results showed a similar increase in dorsiflexion range of motion (p < 0.01, d = 0.51; p < 0.01, d = 0.65, respectively) and passive torque at dorsiflexion range of motion (p = 0.02, d = 0.51 and p < 0.01, d = 0.65, respectively) after foam rolling and vibration foam rolling. Medial gastrocnemius shear elastic modulus decreased only after vibration foam rolling (p < 0.01, d = 0.44). No significant main effects of time were observed in maximal voluntary isometric contraction torque (F = 2.0, p = 0.15,

= 0.119) and drop jump height (F = 1.5, p = 0.24,

= 0.091) after both interventions. Maximal voluntary concentric contraction torque showed a significant main effect of time (F = 7.59, p = 0.02,

= 0.336). However, only after foam rolling, the maximal voluntary concentric contraction torque significantly decreased (p = 0.01, d = 0.39). Our results suggest that vibration foam rolling effectively alters passive muscle properties without decreasing muscle strength and performance.

Abstract
Cabre, HE, Greenwalt, CE, Gould, LM, Hirsch, KR, Blue, MNM, and Smith-Ryan, AE. Exploring the “Athlete’s Paradox”: Division I cross-country runners demonstrate similar muscle characteristics to recreationally trained young adults. J Strength Cond Res 35(11): 3213–3217, 2021—Endurance training can influence body composition and muscle characteristics. Endurance athletes have demonstrated elevated intramuscular fat (IMF), yet individuals with greater body fat also demonstrate elevated IMF. The purpose of this study was to examine differences in muscle characteristics (echo intensity [EI] and muscle cross-sectional area [mCSA]) and body composition between Division I collegiate athletes and college-age adults matched for percent fat (%fat). Thirty cross-country athletes (XC) and 30 normal-weight (NW) recreationally active college students (male athletes: n = 30; female athletes: n = 30; mean ± SD: age: 19.2 ± 1.1 years; body mass: 61.7 ± 8.7 kg; %fat: 18.0 ± 5.2%) underwent a panoramic ultrasound scan of the vastus lateralis to evaluate EI and mCSA. A full-body dual-energy x-ray absorptiometry scan was used to assess fat mass (FM), lean mass (LM), and %fat. Independent t-tests were used to evaluate mCSA, EI, and body composition. Significance level was set at ≤ 0.05. There were no significant differences between the XC and NW cohorts in mCSA (mean difference [MD; XC − NW], −1.30 ± −0.40 cm3; p = 0.340) or EI (MD: 3.97 ± 2.66 a.u.; p = 0.478). Body composition was not different between the groups: FM (MD: −0.14 ± −0.54 kg; p = 0.848), LM (−3.07 ± 1.25 kg; p = 0.268), or bone mineral content (−0.21 ± 0.03 kg; p = 0.120). There were also no significant differences for any outcome variables when stratified by male athletes (p = 0.097–0.468) or female athletes (p = 0.055–0.700). These results suggest that XC athletes may have similar muscle characteristics to NW individuals when matched for %fat. Understanding and tracking muscle characteristics in XC athletes may be important for performance, injury prevention, and the transition to retirement.

Published: September 2021

Abstract
A novel polymer material that is capable of adsorption of Pb2+ and Cu2+ in aqueous solutions has been synthesized. 3-Aminopropyltriethoxysilane was reacted with tetraethylethoxysilane in methanol and aqueous solution of HCl to yield 3-aminopropypolysiloxane (APP). Reacting the APP with ethylchloroacetate in triethylamine yielded a functionalized 3-aminopropypolysiloxane (FAPP). The FAPP was reacted with urea to yield urea immobilized polysiloxane. FTIR spectra of the APP showed major absorption bands (cm−1) at: 1032.5-1042.7 (Si-O-Si), while the Urea-immobilized polysiloxanes (APPU) showed major absorption bands (cm−1) at: 3200 − 3400 υ(NH), 2929 − 2957 υ(C-H), 1505-1643 (C=O, C=C, C=N), and 1032.5-1042.7 (Si-O-Si). SEM-EDX analysis of APP and APPU showed mean pore volumes (nm3) of 113.49 ± 7.91 and 44.89 ± 7.44 respectively, and elemental composition (%) as follows: APP, O (36.68), Si (39.91); FAPP, O (29.43), Si (41.64), Cl (9.06); APPU, O (32.15), Si (28.42), N (25.42). APP maximum percentage adsorption of Pb2+ and Cu2+ in simulated water were 79.44 and 74.81 respectively, while APPU maximum percentage adsorption of Pb2+ and Cu2+ were in the range of 78.36 − 85.44 and 79.63 − 82.87 respectively. The maximum percentage adsorption of Pb2+ and Cu2+ which indicate the sorption capacities of the adsorbents occurred within the pH range of 8-10, contact time between 70-90 min, metal ion concentration of 20-25 ppm, dosage of adsorbent of 0.01 − 0.03 g for Pb2+ adsorption, and 0.04 − 0.05 g for Cu(II), and at a temperature of 90°C. The statistical analyses showed significant difference in the means of the effects of pH, time and concentration as F &gt; Fcrit, except in the case of contact time for Cu2+. Temkin isotherm gave values of R2 in the range of 0.9210 − 0.9735 and best fitted the adsorption process. The urea immobilized polysiloxane (APPU) exhibited very high potential for adsorption of Pb2+ and Cu2+ in industrial effluent up to 100 %.

Authors: Tudor Darija , Kolombo Iva , Tot Ana , Cikojevic Drasko , Simunovic Marko , Skrabic Veselin 
Published: September 2021

Summary
This is a case report of a child with chronic hyponatremia due to the syndrome of inappropriate antidiuretic hormone secretion (SIADH) as a paraneoplastic manifestation of olfactory neuroblastoma (OFN). We hereby report a clinical presentation as well as a pragmatic approach to one of the most common electrolytic disorders in the pediatric population and have emphasized the necessity of involving the sinonasal area in the diagnostic procedure while evaluating possible causes of SIADH. This report indicates that the chronicity of the process along with the gradual onset of hyponatremia occurrence is responsible for the lack of neurological symptoms at the moment of disease presentation.

Learning points

Hyponatremia is not infrequently attributed to SIADH.

Paraneoplastic syndromes are uncommon but they should be considered in the differential diagnosis of pediatric SIADH.

Chronic insidious hyponatremia may not be associated with clear neurological symptoms despite its severity.
Association between circulating insulin-like growth factor 1 and risk of all-cause and cause-specific mortality
Authors: Xie Yu , Huang Changzhi , Zhu Xingchen , Wang Jiayu , Fan Xikang , Fu Zan , Ma Yanan , Hang Dong 
Published: September 2021

Background
Insulin-like growth factor 1 (IGF1) is an important growth factor modulating development, homeostasis, and aging. However, whether and how circulating IGF1 concentrations influence early death risk in the general population remains largely unknown.

Methods
We included 380 997 participants who had serum IGF1 measurement and no history of cancer, cardiovascular disease (CVD), or diabetes at baseline from UK Biobank, a prospective cohort study initiated in 2006–2010. Restricted cubic splines and Cox proportional hazards regression models were used to assess the association between baseline IGF-1 concentrations and all-cause and cause-specific mortality.

Results
Over a median follow-up of 8.8 years, 10 753 of the participants died, including 6110 from cancer and 1949 from CVD. Dose–response analysis showed a U-shaped relationship between IGF1 levels and mortality. Compared to the fifth decile of IGF1, the lowest decile was associated with 39% (95% CI: 29–50%), 20% (95% CI: 8–34%), and 39% (95% CI: 14–68%) higher risk of all-cause, cancer, and CVD mortality, respectively, while the highest decile was associated with 17% (95% CI: 7–28%) and 38% (95% CI: 11–71%) higher risk of all-cause and CVD mortality, respectively. The results remained stable in detailed stratified and sensitivity analyses.

Conclusions
Our findings indicate that both low and high concentrations of serum IGF1 are associated with increased risk of mortality in the general population. Our study provides a basis for future interrogation of underlying mechanisms of IGF1 in early death occurrence and possible implications for mitigating the risk.
