The task of this work wass to assess the impact of new organo-mineral complex based on peat Gumiton, enriched with trace elements (B, Mo, Mn), on the yield and quality of spring wheat, including under conditions of technogenic soil pollution. In a series of field experiments on various types of soils of the Kaluga Region and the Republic of Tatarstan of Russia in farms of various forms of ownership, it was shown that the treatment of spring wheat crops of various varieties with Gumiton in various phases of plant development contributed to an increase in yield by 15-25%. Under the conditions of the growing experiment on soddy-podzolic sandy loam soil, double Gumiton treatment of spring wheat crops of Rima variety increases the B content in the grain to 1.4; Mo-by 1.3 times relative to the variants without the use of the drug. Gumiton reduces the accumulation of Cd in grain up to 1.2 times and improves zootechnical indicators of grain-increases the protein content by 0.9%, fat - up to 0.6%. Gumiton is a highly effective complex for use in spring wheat cultivation technologies, which increases the yield and quality of grain and reduces the accumulation of pollutants (heavy metals).

Authors: Susanti Yeni , Ernanto Iwan , Sutjijana Aluysius , Sidiq Sufyan
Published: January 2022

Let $G$ be a connected undirected simple graph of size $q$ and let $k$ be the maximum number of its order and its size. Let $f$ be a bijective edge labeling which codomain is the set of odd integers from 1 up to $2q-1$. Then $f$ is called an edge odd graceful on $G$ if the weights of all vertices are distinct, where the weight of a vertex $v$ is defined as the sum $mod(2k)$ of all labels of edges incident to $v$. Any graph that admits an edge odd graceful labeling is called an edge odd graceful graph. In this paper, some new graph classes that are edge odd graceful are presented, namely some cartesian products of path of length two and some circular related graphs.

Authors: Ghafari Cher , Benusic Michael , Prystajecky Natalie , Sbihi Hind , Kamelian Kimia , Hoang Lindaq
Published: January 2022

Background: The Kappa variant is designated as a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant of interest (VOI). We identified 195 Kappa variant cases in a region of British Columbia, Canada—the largest published cluster in North America. Objectives: To describe the epidemiology of the Kappa variant in relation to other circulating SARS-CoV-2 variants of concern (VOC) in the region to determine if the epidemiology of the Kappa variant supports a VOI or VOC status. Methods: Clinical specimens testing positive for SARS-CoV-2 collected between March 10 and May 2, 2021, were screened for the detection of known circulating VOCs; approximately 50% of specimens were subsequently selected for whole genome sequencing (WGS). Epidemiological analysis was performed comparing the characteristics of Kappa cases to the main circulating variants in the region (Alpha and Gamma) and to non-VOC/VOI cases. Results: A total of 2,079 coronavirus disease 2019 (COVID-19) cases were reported in the region during the study period, of which 54% were selected for WGS. The 1,131 sequenced cases were categorized into Kappa, Alpha, Gamma and non-VOC/VOI. While Alpha and Gamma cases were found to have a significantly higher attack rate among household contacts compared to non-VOI/VOC cases, Kappa was not. Conclusion: Epidemiological analysis supports the designation of Kappa as a VOI and not a VOC. The Alpha and Gamma variants were found to be more transmissible, explaining their subsequent dominance in the region and the rapid disappearance of the Kappa variant. Variant surveillance strategies should focus on both detection of established VOCs and detection of potential new VOCs.

Authors: Tosun Bülent
Published: January 2022

We give an overview of the research related to the topological characterization of Stein domains in complex two-dimensional space, and an instance of their many important connections to smooth manifold topology in dimension four. One goal is to motivate and explain the following remarkable conjecture of Gompf: no Brieskorn integral homology sphere (other than S
3) admits a pseudoconvex embedding in ℂ2, with either orientation. We include some new examples and results that consider the conjecture for families of rational homology spheres which are Seifert fibered, and integral homology spheres which are hyperbolic.

Published: January 2022

In order to process and visualise the monochromatic images of regions of the Sun obtained with the CCD multichannel spectroheliograph, the freely distributed programs ImageJ and ParaView were chosen and then fine-tuned. This reduced the time required to develop the data processing and visualization software for this instrument and also made it easier to make further corrections and additions to it.
Effect of beating process on the physicochemical and textural properties of meat analogs prepared with Cordyceps militaris fruiting body
Authors: Zou Yuan , Yu Xiaoying , Zheng Qianwang , Ye Zhiwei , Wei Tao , Guo Liqiong , Lin Junfang
Published: January 2022

In the present work, Cordyceps militaris fruiting body was used as protein and natural fibrous structure source to prepare animal free patty. The effects of beating process on the structural and textural properties of patty were also evaluated. The results found that C. militaris fruiting body based patty prepared with beating process, showed bright yellow in color, with a uniform and smooth surface, and without obvious crack, before and after cooking. The beating process disrupted the connective tissues in fruiting bodies, let more protein dissolve, and left the un-soluble fiber structure. This helped to form a fibrous structure and good gel matrix in patty, which mainly contributed to the high hardness, chewiness, adhesiveness, and sensory score. Such C. militaris fruiting body based patties also had a good nutritional quality with high protein and essential amino acid content, as well as a special nutrient of cordycepin.

{p=1}

. Both of these operators are heavily explored and have
various applications. We investigate some inclusions results and integral
preserving properties. We also extend the Ruscheweyh and Sheil-Small convolution
preserving properties in the context of these classes. We relate our finding with
the existing known results found in the literature regarding this subject.
Polarization-controlled anisotropy in hybrid plasmonic nanoparticles

Published: January 2022

Anisotropy has played a critical role in many material systems, but its controllable creation and modulation have been a long-lasting challenge for the scientific communities. Polarization-addressed anisotropy appears more attractive among all approaches due to its excellent controllability, simplicity, and accuracy, but only a limited number of material systems are applicable for such a concept, which are largely focused on oriented growth. Here, we establish a polarization-dependent anisotropic etching system made of Au@oligomer core–shell nanoparticles (NPs). As the oligomer coatings can be photochemically degraded via two-photon photolithography, the plasmonic near-field enhancement supported by the Au NP cores renders much faster degradation of the oligomer shells along the polarization, resulting in anisotropic Au@oligomer hybrid NPs. Such shape anisotropy leads to polarization-dependent photoluminescence with embedded dyes of methylene blue, which can be used as single-particle-based polarization detector. The oligomer lobes capped at the sides of the Au NP can also function as a protection agent for anisotropic photochemical growth of Au NPs, which evolve into Au nanorods and mushrooms with controlled irradiation time. Such polarization-directed etching of oligomer shells has unique advantages of high local-selectivity, controllability, and versatility for on-chip nanofabrication, which opens many new opportunities for integrated nanophotonic devices.
Optical generation of strong-field terahertz radiation and its application in nonlinear terahertz metasurfaces
Authors: Ma Zhenzhe , Li Peiyan , Chen Sai , Wu Xiaojun
Published: January 2022

Extremely nonlinear terahertz (THz)-matter interactions and applications have positioned themselves as the next frontier in quantum information, nonlinear optics, and particle acceleration. However, the absence of free-space highly intense THz sources and the diffraction limit, which prevents THz waves from being concentrated to the nanoscale scale, are inhibiting the growth of extreme THz. To address this difficulty, suitably extremely concentrated THz sources are being produced, while (non-)resonant artificial metastructures are being widely used to enhance local fields, resulting in deep-subwavelength (<λ/103) confinement of highly enhanced THz fields in micro-/nano-gaps. We discuss solid-state stable sources of intense THz radiation generated by femtosecond lasers in this Review, with a special emphasis on the lithium niobate-based tilted pulse front approach and the nonlinear THz metasurfaces allowed by it. Finally, we forecast the field’s future directions in extreme THz research.
Direct generation of entangled photon pairs in nonlinear optical waveguides
Authors: Rodríguez Echarri Álvaro , Cox Joel D. , García de Abajo F. Javier
Published: January 2022

Entangled photons are pivotal elements in emerging quantum information technologies. While several schemes are available for the production of entangled photons, they typically require the assistance of cumbersome optical elements to couple them to other components involved in logic operations. Here, we introduce a scheme by which entangled photon pairs are directly generated as guided mode states in optical waveguides. The scheme relies on the intrinsic nonlinearity of the waveguide material, circumventing the use of bulky optical components and their associated phase-matching constraints. Specifically, we consider an optical waveguide under normal illumination, so that photon down-conversion can take place to excite waveguide states with opposite momentum in a spectral region populated by only two accessible modes. By additionally configuring the external illumination to interfere different incident directions, we can produce maximally entangled photon-pair states, directly generated as waveguide modes with conversion efficiencies that are competitive with respect to existing macroscopic schemes. These results should find application in the design of more efficient and compact quantum optics devices.

Authors: Sadighara Parisa , Mohajer Afsaneh , Shamloo Ehsan , Akbari Nader , Vakili Saatloo Naiema
Published: January 2022

Foods are contaminated with natural and man-made radionuclides. The aim of this systematic review was to determine the amount and type of radionuclides in eggs, as well as the biomarker capability of eggs. The research studies with keywords radionuclide, radioisotopes, contamination and egg were searched in PubMed, Scopus, and Science Direct databases, regardless of publication time. A number of 70 studies were obtained and only 13 articles were finally selected according to exclusion, inclusion criteria and quality assessment results. Studies which detected radionuclide in the hen eggs were selected. The highest frequency of radionuclides belonged to Ra-226 and Cs-137. The index of natural radionuclides is Ra-226 and the index of synthetic radionuclides is Cs-137. The local eggs, in addition to determining food contamination, can also be a good biomarker for identifying environmental contamination.
Exploring aspects of New Work: Spirituality at Work in agile organizations
Authors: Moll Tobias
Published: January 2022

The topic spirituality at work is becoming increasingly important in the scientific management research, while various concepts of and approaches to new work are attracting more and more attention regarding for instance the trend toward a knowledge society, digitalization, increasingly intense competition, and uncertain market and working environments, or aspects of demographic changes especially in corporate practice. These two discussion strands currently run separately; I seek to connect them. I outline the contributions and impacts of the scientific discussion about spirituality at work for the challenges discussed in corporate practice conversation on new work regarding rapid innovation, agility, and continual change, employee retention, and meaning and purpose on the example of the healthcare industry, particularly nursing.

Based on initial results on German employer and employee perspectives on spirituality at work, I show that spirituality at work can positively contribute to employees dealing with uncertainty and persistent change in agile work settings, promote employee creativity, and employee retention and employer attractiveness, especially among younger members of Generation Y. Thus, spirituality at work is a resource for both employees and employers. Finally, I discuss spirituality at works’ double-edged sword character and its suitability for HRM in broadly secularized Germany.
The control effect of dual-frequency ultrasonic excitation on the chaotic oscillation of cavitation bubbles
Authors: Wang Xiaojiao , Ning Zhi , Lv Ming
Published: January 2022

Dual-frequency ultrasonic excitation is not only an important mean of inducing ultrasonic cavitation, but also a key approach to control the oscillation characteristics of cavitation bubbles. In this paper, the control effect of dual-frequency excitation on the oscillation characteristics of cavitation bubbles is studied by means of nonlinear dynamic analyses. The results show that both suppression and promotion of the chaotic oscillation of cavitation bubbles can be achieved by dual-frequency excitation, which deeply depends on the parameters setting (second frequency value, pressure amplitude ratio and phase difference). By increasing the second frequency value, reducing the pressure amplitude ratio and keeping the phase difference within a certain range, the transformation of cavitation bubbles from periodic to chaotic oscillation can be promoted. The results of this paper are of great significance for promoting the highly efficient sonochemical reactions.
Regulation of neuronal autophagy and cell survival by MCL1 in Alzheimer’s disease
Authors: Rezaeian Abdol-Hossein , Wei Wenyi , Inuzuka Hiroyuki
Published: January 2022

Maintaining neuronal integrity and function requires precise mechanisms controlling organelle and protein quality. Alzheimer’s disease (AD) is also characterized by functional defects in the clearance and recycling of intracellular components. In fact, neuronal homeostasis involves autophagy, mitophagy, apoptosis, and compromised activity in these cellular processes may cause pathological phenotypes of AD. Therefore, mitophagy is a critical mitochondrial quality-control system, and impaired mitophagy is a hallmark of AD. Myeloid cell leukemia 1 (MCL1), a member of the pro-survival B-cell lymphoma protein 2 (BCL2) family, is a mitochondrially targeted protein that contributes to maintaining mitochondrial integrity. Mcl1-knockout mice display peri-implantation lethality. Studies on conditional Mcl1-knockout mice have demonstrated that MCL1 plays a central role in neurogenesis and neuronal survival during brain development. Accumulating evidence indicates the critical role of MCL1 as a regulator of neuronal autophagy, mitophagy, and survival. In this review, we discuss the emerging neuroprotective function of MCL1 and how dysregulation of MCL1 signaling is involved in the pathogenesis of AD. Because members of the pro-survival BCL2 family proteins are promising targets of pharmacological intervention with BH3 mimetic drugs, we also discuss the promise of MCL1-targeting therapy in AD.
Delta Oscillations Coordinate Intracerebellar and Cerebello-Hippocampal Network Dynamics during Sleep
Authors: Torres-Herraez Arturo , Watson Thomas C. , Rondi-Reig Laure
Published: January 2022

During sleep, the widespread coordination of neuronal oscillations across both cortical and subcortical brain regions is thought to support various physiological functions. However, how sleep-related activity within the brain's largest sensorimotor structure, the cerebellum, is multiplexed with well-described sleep-related mechanisms in regions such as the hippocampus remains unknown. We therefore simultaneously recorded from the dorsal hippocampus and three distinct regions of the cerebellum (Crus I, lobule VI, and lobules II/III) in male mice during natural sleep. Local field potential (LFP) oscillations were found to be coordinated between these structures in a sleep stage-specific manner. During non-REM sleep, prominent δ frequency coherence was observed between lobule VI and hippocampus, whereas non-REM-associated hippocampal sharp-wave ripple activity evoked discrete LFP modulation in all recorded cerebellar regions, with the shortest latency effects in lobule VI. We also describe discrete phasic sharp potentials (PSPs), which synchronize across cerebellar regions and trigger sharp-wave ripple suppression. During REM, cerebellar δ phase significantly modulated hippocampal theta frequency, and this effect was greatest when PSPs were abundant. PSPs were phase-locked to cerebellar δ oscillation peak and hippocampal theta oscillation trough, respectively. Within all three cerebellar regions, prominent LFP oscillations were observed at both low (δ, <4 Hz) and very high frequencies (∼250 Hz) during non-REM and REM sleep. Intracerebellar cross-frequency analysis revealed that δ oscillations modulate those in the very high-frequency range. Together, these results reveal multiple candidate physiological mechanisms to support “offline,” bidirectional interaction within distributed cerebello-hippocampal networks.

SIGNIFICANCE STATEMENTSleep is associated with widespread coordination of activity across a range of brain regions. However, little is known about how activity within the largest sensorimotor region of the brain, the cerebellum, is both intrinsically organized and links with higher-order structures, such as the hippocampus, during sleep. By making multisite local field potential recordings in naturally sleeping mice, we reveal and characterize multiple sleep stage-specific physiological mechanisms linking three distinct cerebellar regions with the hippocampus. Central to these physiological mechanisms is a prominent δ (<4 Hz) oscillation, which temporally coordinates both intracerebellar and cerebello-hippocampal network dynamics. Understanding this distributed network activity is important for gaining insight into cerebellar contributions to sleep-dependent processes, such as memory consolidation.
Geodetic and seismological analysis of the CROPOS ZAGR station kinematics during the Zagreb 2020 ML 5.5 earthquake

Published: January 2022

The CROPOS’s ZAGR stations, one of 33 stations of the Croatian permanent GNSS (Global Navigation Satellite System) network CROPOS (Croatian Positioning System), is located in Zagreb’s city centre. For the first time, motion of one of the CROPOS stations (the ZAGR station) during an earthquake shake (the Zagreb 2020 ML5.5) was analysed by the PPK (Post-Processed Kinematic) method using all available GNSS signals (GPS – Global Positioning System, GLONASS – GLObalnaya NAvigatsionnaya Sputnikovaya Sistem, Galileo, Bei-Dou) and seismologically interpreted. The ZAGR station is situated about 9 km to the south-southeast of the earthquake’s epicentre. The analysis showed that the station’s movements, i.e. combined surface and building motion, during the shake was far above the noise level and enabled the assessment of the station’s kinematics: movements in the range of approx. 13 cm in direction north–south (N–S) and approx. 6 cm in direction east–west (E–W). However, movements in the vertical direction were slightly above the noise level. Even though the ZAGR station kinematic behaviour was pronounced, no permanent displacement was identified. The seismological analysis showed that the ZAGR station recorded the onset of the SV-waves on the N–S component, surface waves on the N–S (predominantly Rayleigh waves) and E–W (mainly Love waves) components. The resolution of 1 s of the results of the PPK method have enabled a thorough analysis of the ZAGR station kinematics and pointed out the usefulness of the method in earthquake observations.

Published: January 2022

Following the 22 March 2020 ML 5.5 earthquake near Zagreb, Croatia, the citizens became increasingly interested in earthquakes and the multitude of simultaneous visitors caused the webpage with Croatian Seismological Survey reports on earthquakes to crash. To remedy the situation, seismologists used social network accounts to provide information, using the opportunity to educate the citizens on basic concepts of seismology, earthquake preparedness and the occurring seismic sequence. Citizens’ feedback was useful to improve the communication, but required extensive moderation. In July 2020, three seismologists from the Department of Geophysics, Faculty of Science, University of Zagreb, one from the Slovenian Environment Agency, and a psychologist from the Croatian Catholic University conducted a poll to find out which sources of information citizens mostly use, their knowledge about earthquakes, and the level of fear they were experiencing due to the earthquakes. Most respondents relied on institutional sources of information and their knowledge on different aspects of earthquake preparedness increased relatively compared to the time before the earthquake. The majority of respondents was extremely worried on the day of the mainshock, predominantly because they were concerned of a possible stronger event, their safety and the safety of their close ones.
Dialogic Autoethnography
Authors: Wilkes Rima
Published: January 2022

It is widely held that positional characteristics such as gender, age, education and race reflect experience. Here I draw attention to the fact that the understanding of how these and other positional characteristics matter is pre-determined by the theoretical positionality that we forget about. To show that theorizing is to take a position (on positionality), I present a new “dialogic autoethnography” of the two years I spent online dating. In this dialogic autoethnographic approach, I tell the story and then engage in a dialogue with a series of composite theoretical “others” each of which has a different take on the story. These others include a socio-biologist, a sexual fielder, an intersectionalist, and a loving relater. In so doing, I proffer a broadened conceptualization of positionality and its relationship to both story and theory. Theorizing affects how we understand positionality within a story. Theorizing is positionality.
(Gas)lighting Their Way to Coercion and Violation in Narcissistic Abuse
Authors: Howard Vickie
Published: January 2022

Narcissistic abuse is a hidden form of abuse and remains under-recognized in society and within the helping professions, partly due to victim difficulties in articulating the manipulative behaviors they have experienced. Though research focusing on narcissism is extensive, there is a distinct lack of research into the abusive behaviors individuals with severe narcissistic traits use against others and subsequent victim experiences. With the aim of raising awareness of this form of abuse, the following evocative account utilizes autoethnographic memory work and portrays personal experiences of narcissistic abuse—specifically, gaslighting behavior, pathological dishonesty, and intimate abuse. The autoethnographic methods of this article are aligned with social justice and feminist epistemologies. Suppositions are offered to the reader centered upon trauma, loss, and healing in the context of the author’s personal experiences and inherent values as a mental health nurse and educator. Key reflections regarding the use of memory as method along with procedural, relational, and ethical considerations determine how the autoethnography and its portrayal may have been shaped.

Published: January 2022

OBJECTIVE

To examine perceived barriers and motivators for smoking cessation among caregivers of inpatient pediatric patients.

METHODS

From December 2014 to June 2018, trained tobacco counselors conducted motivational interviews (MI) with caregivers of inpatient pediatric patients ages 0 to 17, who participated in the intervention arm of a smoking cessation randomized controlled trial. By using NVivo 12 software, the first MI session with each caregiver was evaluated by 3 individuals to identify and categorize motivators and barriers; agreement among reviewers was reached. Barriers and motivators were examined in bivariable analysis with χ2 or Fisher’s exact tests for categorical factors and with t-tests for continuous factors by using SAS 9.4 software.

RESULTS

Of the 124 caregivers randomized to intervention, 99 subjects (80%) completed ≥1 MI sessions. The most prevalent barriers to cessation were stress (57%) and social influence (37%).

The most prevalent motivators were desire to lead a healthy life (54%) and desire to improve the child and family’s well-being (47%). Older parent age was associated with wanting to lead a healthy life, and younger child age was associated with wanting to improve the child and family’s well-being.

CONCLUSIONS

Understanding barriers and motivators to cessation among caregivers is crucial in reducing pediatric secondhand smoke (SHS). When developing caregiver cessation programs in an inpatient clinic encounter, caregiver barriers and motivators may help in targeting education and strategies to help counselors and clinicians better identify and support caregivers who wish to quit smoking.
Best Practice in Intravascular Lithotripsy
Authors: Honton Benjamin , Monsegu Jacques
Published: January 2022

Intravascular lithotripsy (IVL) is a novel approach to lesion preparation of severely calcified plaques in coronary and peripheral vessels. Lithotripsy is delivered by vaporising fluid to create an expanding bubble that generates sonic pressure waves that interact with arterial calcification. Available data indicate that IVL leads to increased vessel compliance before stent implantation with high efficacy and an excellent safety profile. Since it gained the CE mark in 2017, and with improved operator experience, the use of IVL has expanded into more complex clinical situations. This review focuses on the best practice for IVL use in the cath lab, based on 3 years of experience with the technology and the latest scientific data from the Disrupt CAD clinical trials.

Brauchen wissenschaftliche Bibliotheken heute noch Erwerbungsprofile?
Authors: Bissantz Clara , Jusow Anna
Published: January 2022

Erwerbungsprofile sind Konzepte, anhand derer der Bestand von Bibliotheken aufgebaut und erweitert werden kann. In der vorliegenden Hausarbeit wird der Frage nachgegangen, ob und wenn ja, welchen Mehrwert Erwerbungsprofile für wissenschaftliche Bibliotheken haben. Besonderes Augenmerk liegt dabei auf der Etatpolitik, der Publikationsflut sowie den E-Medien. Die Autorinnen kommen zu dem Schluss, dass Erwerbungsprofile ein hilfreiches Konzept sein können, wenn es um das Bestands- und Erwerbungsmanagement geht. Zwar können Probleme bei der Einführung eines Erwerbungsprofils auftreten, wie zum Beispiel die eingeschränkte Eignung für kleinere oder finanziell weniger gut ausgestattete Bibliotheken. Doch da Erwerbungsprofile anpassbare, transparente und objektive Instrumente darstellen, muss die Frage nach Eignung jede Einrichtung individuell für sich beantworten. Ob Erwerbungsprofile langfristig ein sinnvolles Konzept für Bibliotheken darstellen, sollten Längsschnittstudien eruieren, indem sie objektive Richtlinien für den Bestand festlegen.

The composition of biologically active compounds of Calocybe gambosa (Lyophyllaceae) was analysed, and the antioxidant and cytotoxic activities were tested in vitro. C. gambosa was low in energy, fat, and carbohydrates, but rich in proteins and fibres. The total polyphenol content in the extracts was low (23.08 ± 0.67 in aqueous and 24.99 ± 4.25 μg GA mg−1 of extract in methanolic extract). The methanolic extract showed anti-DPPH radical activity with an IC50 of 626.10 ± 25.20 μg mL−1. The sample of C. gambosa is rich in nucleotides and amino acids responsible for its pleasant taste. The nucleoside and 5′-monophosphates contents were 0.97 mg g−1 and 2.32 mg g−1 of dry mushroom, respectively. The contents of essential and non-essential amino acids were 18.41 ± 0.06 and 41.75 ± 0.30 mg g−1 d.w., respectively. The percentages of saturated and unsaturated fatty acids were 42.6% and 57.4%, respectively. The most abundant water-soluble and fat-soluble vitamins were B1 and E, respectively. Cytotoxic effect of the extracts was examined against different cancer cell lines, and the best cytotoxicity was showed by the peptide extract against colon cancer cell line LS174.

Research of the determination method of furfurals and furosine in milk and the application in the quality evaluation of milk
Authors: Shi Xiaomei , Wu Qiong , Ren Dandan , Wang Shuya , Xie Yunfeng
Published: January 2022

The heat treatment process usually affects the quality and safety of milk and could produce different compounds, including furosine and furfurals. To help evaluate the effect of different heating temperatures on furfurals, a method based on gas chromatography-mass spectrometry (GC-MS) combined with QuEChERS (quick, easy, cheap, effective, rugged, and safe) extraction technology was used to detect four furfural compounds, including furfural, 2-acetylfuran, 5-methyl-2-furfural, and 5-hydroxymethyl-2-furfural. A sample extraction was performed with acetonitrile, and the use of both octadecylsilyl (C18) and primary secondary amine (PSA) sorbents can provide satisfactory recoveries. The determination of furosine was performed by using a high performance of liquid chromatography method (HPLC), and the milk samples were hydrolyzed with HCl for 18 h at 110°C. Under the optimized conditions, good linearity was obtained with linear correlation coefficients (R2) above 0.99, and the recovery values from the spiked samples were 88.1–109.5%. The limits of detection were in the range of 0.005 mg/kg–0.015 mg/kg. The established GC-MS and HPLC methods were successfully applied to market milk samples and heat-treatment samples. The highest detection values for 5-hydroxymethyl-2-furfural and furosine were 0.051 mg/kg and 593.2 mg/100 g protein, respectively, in charcoal-flavored fermented milk. It showed a high correlation between the formation of 5-hydroxymethyl-2-furfural with the treatment temperature and time, and the maximum content was 0.886 mg/kg after heating for 180 min at 100°C. However, there was no noticeable linear increase of furosine concentrations when certain temperatures and heating times were reached; the maximum value was 55.0 mg/L after heating for 60 min at 100°C, and 55.4 mg/L after heating for 150 min at 80°C.

Published: January 2022

The article describes a method of calculating the stability of fill slopes, including the construction of the most probable sliding surface and the determination of plastic deformations areas with elastic and elastoplastic (mixed task) distribution of stresses in the soil massif. The comparative stability calculations results of the "embankment - weak foundation" systems are presented, the data for which were taken from scientific articles published by other authors. According to these calculation results, the stress and displacement fields arising in the "embankment - weak base" system, the position and shape of the areas of plastic deformations constructed both on the basis of the Coulomb - Mohr strength condition and on the basis of solving a mixed problem of the theory of elasticity and the theory of plasticity of soils the article has comparison of numerical values of the stability coefficients and the safety coefficients of a weak. It is established that the replacement of the soil mass of the embankment with an equivalent load, as is often done in engineering calculations, significantly transforms the stress and displacement fields in the soil mass of the base, the position and shape of the areas of plastic deformation and, ultimately, entails obtaining unreliable results. The article shows the results of calculations performed using the FEA computer program developed by one of the authors and the Plaxis software package are in satisfactory agreement: the stress and displacement isofields practically coincide, plastic areas have similar dimensions, shape and position in the soil mass, which allows us to recommend the FEA computer program for practical use in calculating the stability of slopes and slopes, as well as the "embankment - weak foundation" system.

The object of research is the humidity regime in external enclosing structures coated with paints with different vapor permeability: ash-silicate, silicate, acrylic and silicone. The purpose of the research is to evaluate the effect of a paint-and-varnish coating based on the developed sol-silicate paint on the change in the moisture regime of the wall, depending on the type of construction. Comparison of the effectiveness of the use of various paints and varnishes is carried out. The properties of the developed sol-silicate paint for finishing the walls of buildings are described. The results of calculating the influence of paints and varnishes on the humidity regime in the walls are carried out. To assess the humidity regime, a technique was used based on the determination of the outside air temperature, with a decrease to which condensation begins to fall out in the walls. This technique makes it possible to compare with high accuracy the humidity conditions in various enclosing structures. Comparison of the humidity regime in the walls of various designs is presented: aerated concrete (from blocks of grades D400, D600), brick, expanded clay concrete. In brick and expanded clay enclosing structures, the influence of the type of insulation (mineral wool mats, expanded polystyrene) on the humidity regime in the walls was also assessed. In the course of research, the thickness of the paint layer varied from 0.2 to 0.6 mm. According to the results of the research carried out in the article, it is shown that when using sol-silicate paint in enclosing structures, the temperature of the onset of condensation and the likelihood of condensation are reduced in comparison with acrylic, silicate and silicone paints. Recommendations are given on the choice of the type of facade paint, taking into account the humidity regime inside the fences of various designs.

Entendendo o empreendedorismo como um esforço de expressão singular, o objetivo deste trabalho é refletir sobre de que forma os três eixos da economia da confiança (dinâmica entre pares, confiança entre desconhecidos e abundância de recursos) podem orientar a experiência empreendedora contemporaneamente. Apoiando-se em revisão bibliográfica, discutiremos o empreendedorismo atualmente a partir de sua interface com as tecnologias digitais de comunicação.
Ocidente pós-11 de Setembro: perversão de ideais religiosos e a representação midiática do terrorismo
Authors: Sanches Lilian Ribeiro
Published: January 2022

Com base nos postulados de Bauman, Morin, Moscovici e Rapoport, o presente artigo se propõe a investigar a relação travada entre o projeto autoritário da Al Qaeda, que teve seu ápice com a concretização dos ataques de 11 de Setembro, e a influência da mídia na construção da representação social do terrorismo no Ocidente. De forma até então inédita, a instrumentalização política dos acontecimentos contribuiu para a disseminação de um pânico moral a partir do que se convencionou chamar de "ameaça terrorista", ampliando a percepção de poder do grupo entre a opinião pública, desencadeando a "guerra ao terror" e cristalizando estereótipos.  Com o intuito de fomentar o debate sobre o tema, o trabalho pretende apresentar uma análise quantitativa da cobertura jornalística das edições digitais da Folha de S.Paulo e The New York Times nos marcos de um, dez e quinze anos após o 11 de Setembro.
On the Koebe Quarter Theorem for Polynomials
Authors: Стоколос Олександр Михайлович , Dillies Jimmy , Dmitrishin Dmitriy , Smorodin Andrey
Published: January 2022

The Koebe One Quarter Theorem states that the range of any Schlicht function contains the centered disc of radius 1/4 which is sharp due to the value of the Koebe function at −1. A natural question is finding polynomials that set the sharpness of the Koebe Quarter Theorem for polynomials. In particular, it was asked in [7] whether Suffridge polynomials [15] are optimal. For polynomials of degree 1 and 2 that is obviously true. It was demonstrated in [10] that Suffridge polynomials of degree 3 are not optimal and a promising alternative family of polynomials was introduced. These very polynomials were actually discovered earlier independently by M. Brandt [3] and D. Dimitrov [9]. In the current article we reintroduce these polynomials in a natural way and make a far-reaching conjecture that we verify for polynomials up to degree 6 and with computer aided proof up to degree 52. We then discuss the ensuing estimates for the value of the Koebe radius for polynomials of a specific degree.
Understanding the Effects of Urban Form and Navigational Aids on Wayfinding Behaviour and Spatial Cognition

In an age in which navigators can simply follow the represented route on their smartphone to get to their desired destination, is there any need for signage and urban legibility? This study aims to explore the effects of urban form and different navigational aids on visitors’ spatial cognition and wayfinding behavior. Thirty-eight participants were placed in one of three groups: i) a paper map only; ii) smartphones with the Google Maps app; and, iii) no navigational aids (local signage only). Participants were asked to find six pre-determined tourist destinations in central Brisbane, Australia, while they were thinking aloud. Post-task tests showed that participants in the group without personal navigational aids were more successful in landmark recognition than map users. Those who used paper maps performed best in route accuracy and street-naming tests. However, across all the spatial recognition tests, the GPS group was systematically neither the best nor the worst in terms of acquired spatial knowledge. The findings have the potential to assist urban designers and navigational mapping producers to design more legible urban spaces and more effective wayfinding tools.
Exploring Vernacular Signage Along America's Legacy Roadscapes
Authors: Auffrey Christopher , Hildebrandt Henry
Published: January 2022

The context in which a sign is displayed and viewed, reflecting the surrounding natural, built and socio-cultural environments in which it is placed, is essential for how well a sign is able to perform its intended visual communication function to orient, inform, persuade, and/or regulate. To this end, signage research must give appropriate attention to contextual factors, especially along highways where natural, built, and socio-cultural environments may continually change. This field report describes efforts to document and assess vernacular signage found along America’s legacy highways. Vernacular signs include a range of contextually designed and placed displays, usually connected to unique local businesses. The focus here is on how vernacular signs respond to contextual factors and often control their own contexts, and as such provide insight into the design, placement, and regulation of contemporary signs of all types.

Published: January 2022

ABSTRACT Introduction To compare two different intraoperative fluoroscopy techniques used for closed reduction and percutaneous pinning (CRPP) in pediatric patients with supracondylar humerus fractures (SHF). Materials and Methods Thirty-six patients who underwent SHF surgery from May 2011 to June 2019 were included in the study. During surgery, the classical fluoroscopy method (CFM) was used in 21 patients and the new fluoroscopy method (NFM) was used in the remaining 15 patients. Results The mean age was 5.14±1.13 years in the NFM group and 5.38±1.36 years in the CFM group. Mean operative time was 38.14±5.92 minutes in the CFM group and 21.54±3.48 minutes in the NFM group (p=0.001), while mean fluoroscopy times were 25.65±3.91 seconds and 39.84±7.50 seconds in the NFM and CFM groups, respectively (p=0.001). The NFM and CFM groups demonstrated similar functional capacity as measured by the Mayo Elbow Score (p=0.168). Direct radiographs obtained to measure Baumann’s angle also showed that the two groups had similar results (p=0.848). Conclusions The NFM is a reliable and successful technique as it leads to shorter operative and fluoroscopy times, as well as providing improvement in functional scores and radiological outcomes in short-term follow-up.
