Research on the combustion process in the Fiat 1.3 Multijet engine fueled with rapeseed methyl esters
Authors: Kurczyński Dariusz , Łagowski Piotr , Warianek Michał 
Published: March 2021

Abstract
The aim of the paper is to analyze and evaluate the basic parameters of the combustion process in a modern Fiat 1.3 Multijet diesel engine, fuelled esters (FAME) and diesel oil. During the tests on an engine test bed, the pressure waveforms in the cylinder were measured, on the basis of which the averaged actual indicator graphs were established in the determined engine operating conditions. On their basis, the pressure increase rates were determined and heat release characteristics were prepared based on the equation of the first principle of thermodynamics. The characteristics of the relative amount of heat released and the characteristics of the relative heat release rate were determined. The use of rapeseed methyl esters to supply the engine had an impact on the parameters of the combustion process as compared to its supply with diesel oil. Differences in the waveforms of heat release characteristics of the engine powered by the tested fuels are significantly greater at low loads. At the lowest engine loads, esters burn much faster than diesel oil. With the increase in engine load, the differences in the waveform of heat release characteristics during combustion of these fuels were significantly smaller.
Forest cover assessment using remote-sensing techniques in Crete Island, Greece
Authors: Elhag Mohamed , Boteva Silevna , Al-Amri Nassir 
Published: March 2021

Abstract
Remote-sensing satellite images provided rapid and continuous spectral and spatial information of the land surface in the Sougia River catchment by identifying the major changes that have taken place over 20 years (1995–2015). Vegetation indices (VIs) of normalized difference vegetation index (NDVI), enhanced vegetation index (EVI) and leaf area index were derived for monitoring and mapping variations in vegetation cover. The quantified decrease in NDVI was found to be 4% between 1995 and 2005, and further decreased by 77.1% between 2005 and 2015; it declined back to almost the initial status of 1995. EVI results were inconsistent suggesting that seasonal crops influence the temporal distribution of vegetation cover. The temporal variations in the VIs were important input parameters for the modelling and management of the catchment’s hydrological behaviour. Image classification found that the 4- and the 6-class classifications between 1995 and 2005 were unstable and produced, respectively, a 13.8% and 16.2% total change between classes. Meanwhile, the 8-, 10- and the 12-class showed an almost horizontal line with a minor fluctuation of less than 0.05%. The results of the post-classification change detection analysis indicated a land degradation in terms of natural vegetation losses with sparser or even with no natural vegetation cover.
“We came for the Sluts, but stayed for the Slutsk”: FK Slutsk Worldwide Facebook page between ironic and genuine football fandom
Authors: Fiadotava Anastasiya 
Published: March 2021

Abstract
In spring 2020, with most national football (soccer) leagues being suspended, fans from around the world turned to the Belarusian Premier League — Europe’s only championship to continue amid the COVID-19 pandemic. In March, a group of Australian football fans created the FK Slutsk Worldwide Facebook group, dedicated to the eponymous Belarusian club, which quickly transformed into a diverse online community. Initially, the group demonstrated many features of ironic fandom, with members producing various humorous forms and performing exaggerated loyalty in recognition of the peculiar circumstances behind the intense international focus on an otherwise unremarkable team. As time passed and the Facebook group community evolved, however, the practices of ironic fandom began to give way to attributes of a genuine fandom. Through an examination of the group’s development, this paper makes a case for viewing the relationship between ironic and genuine fandom not in oppositional, but in temporal terms. It argues that, in order for a fandom to sustain itself, it must be rooted in a shared sensibility that is not limited to a sense of irony, and that a transition from ironic to genuine fandom stems from this sensibility taking precedence over the ironic aspect.
Kinetics studies on free radical scavenging property of ceria in polysulfone–ceria radiation resistant mixed-matrix membrane
Authors: Bedar Amita , Singh Beena G. , Tewari Pradip K. , Bindal Ramesh C. , Kar Soumitra 
Published: March 2021

Abstract
Cerium oxide (ceria) contains two stable states of cerium ions (Ce3+ and Ce4+). The presence of these two states and the ability to swap from one state to another (Ce3+ ↔ Ce4+) by scavenging the highly reactive oxygen species (ROS) generated from radiolysis of water, ensure the enhanced stability of polysulfone (Psf) membranes in the γ-radiation environment. In this study, the ROS scavenging ability of ceria was studied. Ceria nanoparticles were found to scavenge ROS like hydroxyl radicals and hydrogen peroxide (H2O2). The H2O2 scavenging is due to the peroxidase-like catalytic activity of ceria nanoparticles. The ROS scavenging is responsible for offering protection to the Psf host matrix and in turn the stability to the Psf-ceria mixed-matrix membranes (MMMs) in γ-radiation environment. Thus, presence of ceria nanoparticles provides an opportunity for utilizing Psf-ceria MMMs in ionizing radiation environment with increased life span, without compromise in the performance.

Published: March 2021

Abstract
The magnetohydrodynamic nanofluid flow comprised of dust particles is carried out in the current investigation. The role of dust nanoparticles on the flow characteristics is vital. The radiative heat phenomena for the interaction of Cu nanoparticle are deliberated in this discussion. However, both water and oil (kerosene) are treated as conventional fluids. Regarding the current applications on nanofluid in industries for the production of several materials, it is important to use the nanoparticles as a coolant. In recent applications, for the CPU cooler Cu-nanoparticle is used because of its high thermal conductivity and as a good conductor of heat. The governing flow characteristics involved with nonlinear properties of partial differential equations are transformed into ordinary differential equations using suitable similarity variables. Further, numerical treatment is imposed using the in-build Matlab code bvp5c. The imitation is carried out for the various profiles using physical parameters and presented graphically. The numerical values for the rate coefficients are presented via tables and deliberated briefly.
Features of solving the direct and inverse scattering problems for two sets of monopole scatterers
Authors: Dmitriev Konstantin V. , Rumyantseva Olga D. 
Published: March 2021

Abstract
Research presented in this paper was initiated by the publication [A. D. Agaltsov and R. G. Novikov, Examples of solving the inverse scattering problem and the equations of the Veselov–Novikov hierarchy from the scattering data of point potentials, Russian Math. Surveys
74 (2019), 3, 373–386] and is based on its results.
Two sets of the complex monopole scattering coefficients are distinguished among the possible values of these coefficients for nonabsorbing inhomogeneities.
These sets differ in phases of the scattering coefficients.
In order to analyze the features and possibilities of reconstructing the inhomogeneities of both sets, on the one hand, the inverse problem is solved for each given value of the monopole scattering coefficient using the Novikov functional algorithm.
On the other hand, the scatterer is selected in the form of a homogeneous cylinder with the monopole scattering coefficient that coincides with the given one.
The results obtained for the monopole inhomogeneity and for the corresponding cylindrical scatterer are compared in the coordinate and spatial-spectral spaces.
The physical reasons for the similarities and differences in these results are discussed when the amplitude of the scattering coefficient changes, as well as when passing from one set to another.
Preregistration in experimental linguistics: applications, challenges, and limitations
Authors: Roettger Timo B. 
Published: March 2021

AbstractThe current publication system neither incentivizes publishing null results nor direct replication attempts, which biases the scientific record toward novel findings that appear to support presented hypotheses (referred to as “publication bias”). Moreover, flexibility in data collection, measurement, and analysis (referred to as “researcher degrees of freedom”) can lead to overconfident beliefs in the robustness of a statistical relationship. One way to systematically decrease publication bias and researcher degrees of freedom is preregistration. A preregistration is a time-stamped document that specifies how data is to be collected, measured, and analyzed prior to data collection. While preregistration is a powerful tool to reduce bias, it comes with certain challenges and limitations which have to be evaluated for each scientific discipline individually. This paper discusses the application, challenges and limitations of preregistration for experimental linguistic research.

Determination of mechanical properties of two-phase and hybrid nanocomposites: experimental determination and multiscale modeling
Authors: Haghighi Mahmoud , Golestanian Hossein , Aghadavoudi Farshid 
Published: March 2021

Abstract
In this paper, the effects of filler content and the use of hybrid nanofillers on agglomeration and nanocomposite mechanical properties such as elastic moduli, ultimate strength and elongation to failure are investigated experimentally. In addition, thermoset epoxy-based two-phase and hybrid nanocomposites are simulated using multiscale modeling techniques. First, molecular dynamics simulation is carried out at nanoscale considering the interphase. Next, finite element method and micromechanical modeling are used for micro and macro scale modeling of nanocomposites. Nanocomposite samples containing carbon nanotubes, graphene nanoplatelets, and hybrid nanofillers with different filler contents are prepared and are tested. Also, field emission scanning electron microscopy is used to take micrographs from samples’ fracture surfaces. The results indicate that in two-phase nanocomposites, elastic modulus and ultimate strength increase while nanocomposite elongation to failure decreases with reinforcement weight fraction. In addition, nanofiller agglomeration occurred at high nanofiller contents especially higher than 0.75 wt% in the two-phase nanocomposites. Nanofiller agglomeration was observed to be much lower in the hybrid nanocomposite samples. Therefore, using hybrid nanofillers delays/prevents agglomeration and improves mechanical properties of nanocomposite at the same total filler content.
Monte Carlo method for the reduction of measurement errors in the material parameter estimation with cavities
Authors: Peter Ronny , Bifano Luca , Fischerauer Gerhard 
Published: March 2021

Abstract
The quantitative determination of material parameter distributions in resonant cavities is a relatively new method for the real-time monitoring of chemical processes. For this purpose, electromagnetic resonances of the cavity resonator are used as input data for the reverse calculation (inversion). However, the reverse calculation algorithm is sensitive to disturbances of the input data, which produces measurement errors and tends to diverge, which leads to no measurement result at all. In this work a correction algorithm based on the Monte Carlo method is presented which ensures a convergent behavior of the reverse calculation algorithm.
Die Netzwerkebenen von Genossenschaften als Innovationsraum – am Beispiel der BÄKO Österreich
Authors: Rößl Dietmar , Pieperhoff Martina , Hyslop Katie 
Published: March 2021

Zusammenfassung
Die Diskussion rund um open innovation versus closed innovation legt nahe, das Innovationsphänomen in Genossenschaften zu untersuchen, da in ihnen auf verschiedenen Netzwerkebenen interagiert wird und man so zu einer differenzierteren Betrachtung kommen kann. Als Untersuchungsobjekt wurde die BÄKO Österreich – die Einkaufsgenossenschaft der Bäcker und Konditoren – als seit Langem bestehende und daher offensichtlich anpassungsfähige Genossenschaft gewählt. Die fünf qualitativen Interviews werden mittels der Gioia-Methode analysiert, um zur Weiterentwicklung der theoretischen Überlegungen zum Innovationsprozess beizutragen. Unsere Untersuchung zeigt, dass die BÄKO Informationen von allen Akteuren aufnimmt und nach ihrer Innovationsrelevanz prüft, sodass Innovationsimpulse von außen und/oder von innen kommen können und so unterschiedlichste Akteursebenen einbezogen werden. Verallgemeinernd zeigen die Ergebnisse, dass in jedem Akteur eine mögliche Quelle für Innovationsimpulse gesehen werden sollte und Genossenschaften an Markterfolg und Legitimation gegenüber ihren Mitgliedern verlieren, wenn sie ihre grundsätzlich vorhandene Innovativität im Interesse der Mitglieder nicht einzusetzen wissen.
A systematic review and meta-analysis of the impact of GLP-1 receptor agonists and SGLT-2 inhibitors on cardiovascular outcomes in biologically healthy older adults
Authors: Strain William D , Griffiths Jonathan 
Published: March 2021

Background: Unintentional weight loss is a hallmark of frailty and is associated with poor outcomes in older adults with type 2 diabetes. As such, the role of pharmacological therapies that facilitate weight loss – namely, sodium- glucose co-transporter-2 (SGLT-2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists – remains uncertain in fitter older adults. We performed a systematic review and meta-analysis to evaluate these agents on major adverse cardiovascular events (MACE) in older adults eligible for participation in cardiovascular outcome trials.Methods: A literature search was performed in MEDLINE, EMBASE, CINAHL, Cochrane Central Registry of Controlled Trials (CENTRAL) and CNKI from inception to 29 June 2020. A class-specific meta-analysis was conducted in older adults (>65 years at recruitment) and compared with the similar analysis in younger (<65 years) adults.Results: Of 761 unique studies identified, nine met the criteria for inclusion, five using GLP-1 receptor agonists and four with SGLT-2 inhibitors. GLP-1 receptor agonists in older adults were associated with a 15.3% (OR 0.847 (95% CI 0.788 to 0.910)) reduction in MACE events, similar to the 16% benefit seen in younger adults. The use of SGLT-2 inhibitors reduced MACE in older participants by 16.9% (OR 0.831 (95% CI 0.699 to 0.989)), numerically superior to the impact in younger patients (OR 0.936 (95% CI 0.787 to 1.113).Conclusions: GLP-1 receptor agonists and SGLT-2 inhibitors reduced MACE outcomes in older adults who were eligible to participate in clinical trials. Whereas this is reassuring for the biologically robust, it should not be extrapolated to frail older adults without further investigation.

Os movementos poboacionais foron decisivos na historia e no desenvolvementosocioeconómico de Galicia. A distribución espacial da poboación estranxeira nun territoriodisperso, onde predomina o carácter fragmentado da propiedade da terra, pode serdeterminante tanto para unha contorna urbana que tende a concentrar a este grupopoboacional como nos espazos fronteirizos e costeiros onde teñen unha maiorrepresentación relativa. Santiago de Compostela, como único municipio de máis de 50.000habitantes con crecemento positivo da poboación -durante os períodos avaliados-,representa un interesante caso de estudo sobre un fenómeno eminentemente urbano. Population movements have been decisive in the history and socioeconomicdevelopment of Galicia. The spatial distribution of the foreign population in a dispersedterritory with a fragmented land ownership can be crucial both for an urban environmentthat tends to concentrate this population group and for border and coastal areas wherethey have a significant representation. Santiago de Compostela, as the only municipality ofover 50,000 inhabitants with a positive population growth during the periods evaluated,represents an interesting case study on an eminently urban phenomenon.

Published: March 2021

BACKGROUND:
Pediatric lung lesions are a group of mostly benign pulmonary anomalies with a broad spectrum of clinical disease and histopathology. Our objective was to evaluate the characteristics of children undergoing resection of a primary lung lesion and to identify preoperative risk factors for malignancy.

METHODS:
A retrospective cohort study was conducted by using an operative database of 521 primary lung lesions managed at 11 children’s hospitals in the United States. Multivariable logistic regression was used to examine the relationship between preoperative characteristics and risk of malignancy, including pleuropulmonary blastoma (PPB).

RESULTS:
None of the 344 prenatally diagnosed lesions had malignant pathology (P &lt; .0001). Among 177 children without a history of prenatal detection, 15 (8.7%) were classified as having a malignant tumor (type 1 PPB, n = 11; other PPB, n = 3; adenocarcinoma, n = 1) at a median age of 20.7 months (interquartile range, 7.9–58.1). Malignancy was associated with the DICER1 mutation in 8 (57%) PPB cases. No malignant lesion had a systemic feeding vessel (P = .0427). The sensitivity of preoperative chest computed tomography (CT) for detecting malignant pathology was 33.3% (95% confidence interval [CI]: 15.2–58.3). Multivariable logistic regression revealed that increased suspicion of malignancy by CT and bilateral disease were significant predictors of malignant pathology (odds ratios of 42.15 [95% CI, 7.43–340.3; P &lt; .0001] and 42.03 [95% CI, 3.51–995.6; P = .0041], respectively).

CONCLUSIONS:
In pediatric lung masses initially diagnosed after birth, the risk of PPB approached 10%. These results strongly caution against routine nonoperative management in this patient population. DICER1 testing may be helpful given the poor sensitivity of CT for identifying malignant pathology.
Application of hybrid asymptotic methods and modern software for mathematical models developing for nonlinear dynamics of structures with variables in time parameters
Authors: Homeniuk S. , Grebenyuk S. , Gristchak D. 
Published: March 2021

The relevance. The aerospace domain requires studies of mathematical models of nonlinear dynamic structures with time-varying parameters.
The aim of the work. To obtain an approximate analytical solution of nonlinear forced oscillations of the designed models with time-dependent parameters.
The research methods. A hybrid approach based on perturbation methods, phase integrals, Galorkin orthogonalization criterion is used to obtain solutions.
Results. Nonlocal investigation of nonlinear systems behavior is done using results of analytical and numerical methods and developed software. Despite the existence of sufficiently powerful numerical software systems, qualitative analysis of nonlinear systems with variable parameters requires improved mathematical models based on effective analytical, including approximate, solutions, which using numerical methods allow to provide a reliable analysis of the studied structures at the stage designing. An approximate solution in analytical form is obtained with constant coefficients that depend on the initial conditions.
Conclusions. The approximate analytical results and direct numerical solutions of the basic equation were compared which showed a sufficient correlation of the obtained analytical solution. The proposed algorithm and program for visualization of a nonlinear dynamic process could be implemented in nonlinear dynamics problems of systems with time-dependent parameters.
