description: Aims: We search for penumbral magnetic fields of opposite polarity and for their correspondence with downflows. Methods: We used spectropolarimetric HINODE data of a spot very close to disk center to suppress the horizontal velocity components as much as possible. We focus our study on 3-lobe Stokes V profiles. Results: From forward modeling and inversions, we show that 3-lobe profiles testify to the presence of opposite magnetic fields. They occur predominately in the mid and outer penumbra and are associated with downflows in the deep layers of the photosphere. Conclusions. Standard magnetograms show that only 4% of the penumbral area harbors magnetic fields of opposite polarity. If 3-lobe profiles are included in the analysis, this number increases to 17%.

description: In a computer experiment the choice of suitable estimators to measure a physical quantity plays an important role. We propose a new direct route to determine estimators for observables which do not commute with the Hamiltonian. Our new route makes use of the Hellmann and Feynman theorem and in a diffusion Monte Carlo simulation it introduces a new bias to the measure due to the choice of the auxiliary function. This bias is independent from the usual one due to the choice of the trial wave function. We used our route to measure the radial distribution function of a spin one half Fermion fluid.

description: High energy photons (>100 MeV) are detected by the Fermi/LAT from GRB 130427A up to almost one day after the burst, with an extra hard spectral component being discovered in the high-energy afterglow. We show that this hard spectral component arises from afterglow synchrotron-self Compton emission. This scenario can explain the origin of >10 GeV photons detected up to ~30000s after the burst, which would be difficult to be explained by synchrotron radiation due to the limited maximum synchrotron photon energy. The lower energy multi-wavelength afterglow data can be fitted simultaneously by the afterglow synchrotron emission. The implication of detecting the SSC emission for the circumburst environment is discussed.

description: La pandemia Covid-19 ha comportato conseguenze e trasformazioni prefigurando scenari inediti sul piano economico, sociale e personale, determinando anche nel campo della ricerca l’urgenza di esplorarne le ricadute. Il volume dà quindi conto delle indagini svolte e in corso, sin dai primi giorni del lockdown, dai docenti e dai collaboratori del Dipartimento di Scienze della Formazione dell’Università Roma Tre, toccando i temi più diversi: dalla didattica a distanza, all’università e nei diversi ordini di scuola, al futuro dei servizi di orientamento, dal lavoro socio-educativo nelle varie tipologie di servizi all’impatto della pandemia sulle comunità, dalle narrazioni ai linguaggi artistici a contrasto di quest’emergenza non solo sanitaria. Si sono così esplorate le diverse educazioni possibili, riassegnando centralità ai processi formativi e al benessere delle persone, provando a tratteggiare nuovi paradigmi e prospettive.
description: La pandemia di Covid-19 ha avuto, a livello mondiale, un impatto importante sulla salute fisica e psico-sociale di adulti e bambini (Pfefferbaum & North, 2020). I contesti educativi e la scuola, che ricoprono un importante ruolo nello sviluppo sociale ed emotivo dei bambini, rappresentando un contesto elettivo non solo per l’apprendimento di competenze accademiche ma anche per imparare a socializzare e relazionarsi, possono proporsi come promotori di interventi volti al benessere dei bambini (Greenberg et al. 2003; Payne et al., 2020). Il CEPIDEAS Junior, è un programma di intervento atto a promuovere, nei bambini della scuola primaria, i comportamenti prosociali. Con prosocialità si intendono tutte quelle azioni caratterizzate dall’intenzione di recare beneficio ad un’altra persona o gruppo, senza un tornaconto personale o una prospettiva di reciprocità̀, come ad esempio condividere, aiutare, consolare, prendersi cura (Eisenberg et al., 2006). La prosocialità svolge un ruolo di prevenzione e di promozione della salute socio-emotiva, con un impatto positivo anche durante un evento catastrofico come quello della pandemia di Covid-19. Vengono presentate nel testo due esperienze di promozione della prosocialità, svolte durante l’emergenza della pandemia di Covid-19.

description: The first high-statistics cross sections for the reactions $γp \to K^{*+} Λ$ and $γp \to K^{*+} Σ^0$ were measured using the CLAS detector at photon energies between threshold and 3.9 GeV at the Thomas Jefferson National Accelerator Facility. Differential cross sections are presented over the full range of the center-of-mass angles, $θ^{CM}_{K^{*+}}$, and then fitted to Legendre polynomials to extract the total cross section. Results for the $K^{*+}Λ$ final state are compared with two different calculations in an isobar and a Regge model, respectively. Theoretical calculations significantly underestimate the $K^{*+} Λ$ total cross sections between 2.1 and 2.6 GeV, but are in better agreement with present data at higher photon energies.

description: We explore the phase diagram of the O($n$) loop model on the square lattice in the $(x,n)$ plane, where $x$ is the weight of a lattice edge covered by a loop. These results are based on transfer-matrix calculations and finite-size scaling. We express the correlation length associated with the staggered loop density in the transfer-matrix eigenvalues. The finite-size data for this correlation length, combined with the scaling formula, reveal the location of critical lines in the diagram. For $n>>2$ we find Ising-like phase transitions associated with the onset of a checkerboard-like ordering of the elementary loops, i.e., the smallest possible loops, with the size of an elementary face, which cover precisely one half of the faces of the square lattice at the maximum loop density. In this respect, the ordered state resembles that of the hard-square lattice gas with nearest-neighbor exclusion, and the finiteness of $n$ represents a softening of its particle-particle potentials. We also determine critical points in the range $-2\leq n\leq 2$. It is found that the topology of the phase diagram depends on the set of allowed vertices of the loop model. Depending on the choice of this set, the $n>2$ transition may continue into the dense phase of the $n \leq 2$ loop model, or continue as a line of $n \leq 2$ O($n$) multicritical points.

description: We review the current status of spin-averaged and spin-dependent parton distribution functions (PDFs) of the nucleon. After presenting the formalism used to fit PDFs in modern global data analyses, we discuss constraints placed on the PDFs by specific data types. We give representative examples of unpolarized and polarized PDFs and their errors, and list open questions in global QCD fitting. Finally, we anticipate how future facilities, with fixed-target and collider experiments, may impact our knowledge of PDFs and reduce their uncertainties.

description: We investigate the convergence of McKean-Vlasov diffusions in a nonconvex landscape. These processes are linked to nonlinear partial differential equations. According to our previous results, there are at least three stationary measures under simple assumptions. Hence, the convergence problem is not classical like in the convex case. By using the method in Benedetto et al. [J. Statist. Phys. 91 (1998) 1261-1271] about the monotonicity of the free-energy, and combining this with a complete description of the set of the stationary measures, we prove the global convergence of the self-stabilizing processes.

description: We present an educational path on the magnetic vector potential A addressed to undergraduate students and to pre-service physics teachers. Starting from the generalized Ampere-Laplace law, in the framework of a slowly varying time-dependent field approximation, the magnetic vector potential is written in terms of its empirical referent, i. e. the conduction current. Therefore, once the currents are known, our approach allows a clear and univocal physical determination of A overcoming the mathematical indeterminacy due to the gauge transformations. We have no need to fix a gauge, since for slowly varying time-dependent electric and magnetic fields, the natural gauge for A is the Coulomb one. We stress the difference between our approach and those usually presented in the literature. Finally, a physical interpretation of the magnetic vector potential is discussed and some examples of calculation of A are analysed.
title: Exploring drivers of capelin (Mallotus villosus) and Atlantic cod (Gadus morhua) population dynamics using Empirical Dynamic Modelling (EDM)
Creators: name: Steele, Reid
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: Capelin (Mallotus villosus) populations on the Newfoundland shelf collapsed in the early 1990s, coinciding with an ecosystem regime shift and greatly reduced capelin biomass which both persist to this day. The dual-regime nature of this stock’s history suggests it may experience nonlinear dynamics, which are difficult to predict using linear models. This thesis explores the application of nonlinear Empirical Dynamic Modelling (EDM) forecasting tools to capelin biomass data, seeking to determine if capelin dynamics are nonlinear, if nonlinear predictive models of capelin population dynamics outperform linear models, what climatic and ecological factors drive nonlinear changes in capelin biomass, and if these driving forces can be measured and compared. In my first chapter, I found capelin dynamics were nonlinear, and EDM predictive models returned equal or improved model diagnostics to linear models in most situations. In my second chapter, I identified a strong positive association between capelin and Atlantic cod dynamics, with both species being driven by long term climatic change and likely to benefit from mild warming. This thesis clearly identifies the utilities of EDM as a tool for use in stock assessment in detecting and forecasting nonlinear stock dynamics, and identifying and characterizing factors driving population dynamics.

description: The project lines out the planned investigation into teachers’ usage and actions within an online learning platform and the relationship between these interactions on their students’ learning outcomes. While studies have already shown strong evidence of the effectiveness of tutoring platforms (such as ASSISTments), it is unclear whether teachers beyond a structured study environment (e.g., with training and coaching on formative assessments) are using these platforms sufficiently well to harness the benefits. The investigation involves a planned analysis of the ASSISTments 2020/2021 dataset loaded on OSF. Analysis plans include the use of multi levelling techniques to investigate teaching practices (most likely the use of assignment and student reports and use of ASSISTment within a synchronized class environment) and their association with outcome factors (likely assignment completion). If the results are conclusive, plans are to use clustering to review profiles of teachers.

description: Recent evidence from observation of the flavor-changing neutral current decay B_s to mu+ mu- by the LHCb collaboration B(B_s to mu^+ mu^-) = (3.2 * 10^{-9}), is consistent with the latest standard model prediction B(B_s to mu^+ mu^-) = (3.23 +- 0.27) * 10^{-9}. While New Physics can still affect this decay amplitude, its contribution is certainly not the dominant one. We analyze branching ratios of the decays B_s to mu+ mu- X, with X = a photon or neutrino anti-neutrino pair, which can mimic B_s to mu+ mu- on portions of the parameter space where X is soft. We perform a model-independent standard model calculation of those processes incorporating heavy quark and chiral symmetries of QCD. We show that the considered contributions contribute to B_s to mu+ mu- at a sub-percent level.

description: SmN is ferromagnetic below 27 K, and its net magnetic moment of 0.03 Bohr magnetons per formula unit is one of the smallest magnetisations found in any ferromagnetic material. The near-zero moment is a result of the nearly equal and opposing spin and orbital moments in the 6H5/2 ground state of the Sm3+ ion, which leads finally to a nearly complete cancellation for an ion in the SmN ferromagnetic state. Here we explore the spin alignment in this compound with X-ray magnetic circular dichroism at the Sm L2,3 edges. The spectral shapes are in qualitative agreement with computed spectra based on an LSDA+U (local spin density approximation with Hubbard-U corrections) band structure, though there remain differences in detail which we associate with the anomalous branching ratio in rare-earth L edges. The sign of the spectra determine that in a magnetic field the Sm 4f spin moment aligns antiparallel to the field; the very small residual moment in ferromagnetic SmN aligns with the 4f orbital moment and antiparallel to the spin moment. Further measurements on very thin (1.5 nm) SmN layers embedded in GdN show the opposite alignment due to a strong Gd-Sm exchange, suggesting that the SmN moment might be further reduced by about 0.5 % Gd substitution.

description: -situ sorbent amendment is a relatively low-cost, low-impact approach for remediation of soil contaminated with heavy metals (HMs), and thus is considered a way to be favored in developing countries. In this study, materials of non-hazardous, alkaline agronomic and industrial by-products were used as sorbents to explore their capacity of in situ immobilization of multiple HMs in mining-impacted arable soil. These sorbents included fly ash (FA), biochar (BC) and apatite (AP) and they were implemented with varying ratios of combinations. Results of soil microcosm tests showed that after incubation for 90 days, concentrations of Pb, Zn, and Cd in their exchangeable forms determined by a sequential extraction method significantly decreased in amended soils, as opposed to the unamended control. Of the five sets of amendments, the composite of FA, BC, and AP resulted in the maximum reduction (up to 80%) in the mobility of Pb, Zn, and Cd in soils. The mechanisms underlying the immobilization of HMs in amended soils might involve processes of surface precipitation, ion exchange and complexation, in which the physicochemical properties of sorbent materials played an important role. The immobilization efficacy of sorbent amendments on HMs in soil was further supported by pot experiments in which significant inhibition of HM accumulation in the belowground and aboveground tissues of maize was observed after 50-day cultivation in amended soils as compared with control soil. Together, these results suggest that the application of cost-saving and environmentally friendly materials derived from wastes as sorbents to remediate soils contaminated with multiple HMs is promising for developing countries like Vietnam.

description: Asthma, a major cause of disability and reduced quality of life, has a high global prevalence and burden of death. Despite the propitious guidelines, a substantial portion of asthmatics reportedly have poorly controlled disease. In the current study, we have examined risk factors for uncontrolled asthma in specialty clinics and its association with impaired quality of life. A multicentre cross-sectional survey of asthma patients, 18 years and older, was conducted in Trinidad. Asthma Control Test (ACT) and the Juniper Mini Asthma Quality of Life Questionnaire (Mini AQLQ–J) were used to assess the disease control and quality of life, respectively. Data were analyzed using the Chi-square test and multivariable logistic regression controlling for gender. Of a total of 428 patients included, asthma was uncontrolled in 72.4% and asthma related quality of life was moderate to severely impaired in 86% of the studied population. In the multivariate regression models, poorly controlled asthma was associated with obesity (OR 2.25; 95% CI 1.30–3.39), late-onset asthma (OR 1.72; 95% CI 1.04–2.84), features of sleep apnea (OR 1.77; 95% CI 1.01–3.07) and depression (OR 2.01; 95% CI 1.04–3.86). Impaired quality of life was associated with Indo-Caribbean ethnicity (OR 3.19; 95% CI = 1.68–6.06). In this Caribbean population, uncontrolled asthma was independently associated with obesity, late-onset disease, and comorbidities of sleep apnea and depression. Poor asthma-related quality of life was independently associated with Indo-Caribbean ethnicity.

description: The IceCube neutrino observatory has detected two cascade events with energies near 1 PeV. Without invoking new physics, we analyze the source of these neutrinos. We show that atmospheric conventional neutrinos and cosmogenic neutrinos (those produced in the propagation of ultra-high- energy cosmic rays) are strongly disfavored. For atmospheric prompt neutrinos or a diffuse background of neutrinos produced in astrophysical objects, the situation is less clear. We show that there are tensions with observed data, but that the details depend on the least-known aspects of the IceCube analysis. Very likely, prompt neutrinos are disfavored and astrophysical neutrinos are plausible. We demonstrate that the fastest way to reveal the origin of the observed PeV neutrinos is to search for neutrino cascades in the range below 1 PeV, for which dedicated analyses with high sensitivity have yet to appear, and where many more events could be found.

description: Anisotropic and inhomogeneous metamaterial shells are studied in order to exploit all their resonant mode richness. These multilayer structures are based on a cylindrical distribution of radially dependent constitutive parameters including an inner void cavity. Shell, cavity and whispering gallery modes are characterized, and special attention is paid to the latter ones. The whispering gallery modes are created at the boundary layers of the shell with the background and energy localization is produced with highly radiative characteristics. These low-Q resonant states have frequencies that are independent of the shell thickness. However, their quality factors can be controlled by the number of layers forming the shell, which allows confining electromagnetic waves at the interface layers (internal or external), and make them suitable for the harvesting of electromagnetic energy.

description: В статье представлен аналитический обзор материалов работы социально-политических секций состоявшейся 25-28 сентября 2019 г в Санкт-Петербурге Международной научной конференции «Русский логос-2: Модерн - границы контроля». Показано, что обсуждение на конференции проблематики разнообразных течений русской мысли конца XIX - начала XX вв., в широком смысле - идеологии русского модерна, до сих пор остается эксклюзивной формой актуализации в интеллектуальных практиках проблем современного российского общества. Базовой дилеммой рефлексии этих проблем является смысловая двойственность между логикой революционного требования преобразовать социально-политическую реальность российского государства и консервативной тенденцией, составляющей изнанку революционного праксиса, и наоборот, между консервативной логикой сохранения основ нормализованного порядка жизни и невозможностью, что особенно характерно для интеллигенции эпохи модерна, выдержать страшное зрелище коренной несправедливости социального порядка. Сопутствующая сознанию этой двойственности проблема самой возможности осмысленного праксиса, способного вывести по ту сторону от означенной дилеммы, как собственная проблема всякого модернистского сознания, выражает теоретическую и практическую суть данного конфликта.
Ключевые слова: русский модерн, марксизм, родовая сущность человека, русская революция, мессианизм, консерватизм, народничество, консервативный либерализм, анархизм, космическое хозяйство.

description: To investigate associations between obstructive sleep apnea (OSA) and readmission risk after hospitalization for asthma exacerbation. We conducted a retrospective, population-based cohort study using State Inpatient Databases from seven U.S. states (Arkansas, California, Florida, Iowa, Nebraska, New York, and Utah) from 2010 to 2013. We identified all adults (aged 18–54 years) hospitalized for asthma exacerbation. The outcome measure was all-cause readmissions within one year after hospitalization for asthma exacerbation. To determine associations between OSA and readmission risk, we constructed negative binomial regression models estimating the incidence rate ratio (IRR) for readmissions and Cox proportional hazards models estimating hazard rate (HR) for the time-to-first readmission. Among 65,731 patients hospitalized for asthma exacerbation, 6,549 (10.0%) had OSA. Overall, OSA was associated with significantly higher incident rate of all cause readmission (1.36 vs. 0.85 readmissions per person-year; unadjusted IRR 1.60; 95%CI 1.54–1.66). Additionally, OSA was associated with higher incident rates of readmissions for five major diseases—asthma (IRR 1.21; 95%CI 1.15–1.27), COPD (IRR 2.03; 95%CI 1.88–2.19), respiratory failure (IRR 3.04; 95%CI 2.76–3.34), pneumonia (IRR 1.67; 95%CI 1.49–1.88), and congestive heart failure (IRR 3.78; 95%CI 3.36–4.24), compared to non-OSA. The Cox model demonstrated that patients with OSA had significantly higher rates for all-cause readmission compared to those without OSA (HR 1.56; 95% CI 1.50–1.62). These associations remained significant after adjustment for confounders. The observed association of OSA with a higher risk of readmissions after hospitalization for asthma exacerbation underscores the importance of identifying coexistent OSA in this population and optimizing both OSA and asthma management.

The article presents the results of studies of the moisture-proof properties of polymer packaging for white crystalline sugar under various temperature and humidity storage conditions. The most optimal characteristics of polymer packaging for sugar have been determined, including the use of an inner liner bag made of polyethylene film with a thickness of at least 60 microns for additional protection of sugar from moisture.

description: To investigate the current prevalence of physician-diagnosed obstructive airway diseases by respiratory symptoms and by sex in Sweden and Finland. In 2016, a postal questionnaire was answered by 34,072 randomly selected adults in four study areas: Västra Götaland and Norrbotten in Sweden, and Seinäjoki-Vaasa and Helsinki in Finland. The prevalence of asthma symptoms was higher in Norrbotten (13.2%), Seinäjoki-Vaasa (14.8%) and Helsinki (14.4%) than in Västra Götaland (10.7%), and physician-diagnosed asthma was highest in Norrbotten (13.0%) and least in Västra Götaland (10.1%). Chronic productive cough was most common in the Finnish areas (7.7–8.2% versus 6.3–6.7%) while the prevalence of physician-diagnosed chronic bronchitis (CB) or chronic obstructive pulmonary disease (COPD) varied between 1.7 and 2.7% in the four areas. Among individuals with respiratory symptoms, the prevalence of asthma was most common in Norrbotten, while a diagnosis of COPD or CB was most common in Västra Götaland and Seinäjoki-Vaasa. More women than men with respiratory symptoms reported a diagnosis of asthma in Sweden and Seinäjoki-Vaasa but there were no sex differences in Helsinki. In Sweden, more women than men with symptoms of cough or phlegm reported a diagnosis of CB or COPD, while in Finland the opposite was found. The prevalence of respiratory symptoms and corresponding diagnoses varied between and within the countries. The proportion reporting a diagnosis of obstructive airway disease among individuals with respiratory symptoms varied, indicating differences in diagnostic patterns both between areas and by sex.

description: In this paper we will deform a ABJ theory in $\mathcal{N}= 3$ harmonic superspace without breaking any supersymmetry. We will analyse this ABJ theory and show that it retains the full $\mathcal{N}= 6$ supersymmetry. We will then analyse the gauge fixing and ghost terms for this model in various gauges. We will also analyse the corresponding BRST and anti-BRST symmetries of this model.

description: The AMADEUS collaboration has the goal to perform unprecedented measurements in the field of the low-energy charged kaons-nuclei interactions, by implementing the existing KLOE detector with a dedicated setup in the inner region. As a preliminary step towards the realization, the AMADEUS team has analyzed the existent 2002-2005 KLOE data, studying the processes resulting from the negative kaons nuclear absorption in the entrance wall of the KLOE Drift Chamber (containing mostly carbon) and in the gas filling it, mostly helium. Processes containing Lambda-p and Lambda-d in the final state were looked for, together with the search for the Lambda(1405) going in both the neutral and the charged Sigma-pi channels. These analyses produced unique results, proving the possibility to obtain, for the first time, invariant mass spectra of the Lambda(1405) for all the possible decay channels. This was possible thanks to the unique features of the KLOE detector, including the excellent photon detection of its calorimeter. In addition to these results, other interesting effects like the Sigma->Lambda internal conversion could be investigated. Preliminary results on the Sigma+pi- decay channel and on the Sigma->Lambda internal conversion will be presented.

description: We revisit the problem of spin-mediated superconducting pairing at the antiferromagnetic quantum-critical point with the ordering momentum (π,π) = 2k_F. The problem has been previously considered by one of the authors. However, it was later pointed out that that analysis neglected umklapp processes for the spin polarization operator. We incorporate umklapp terms and re-evaluate the normal state self-energy and the critical temperature of the pairing instability. We show that the self-energy has a Fermi-liquid form and obtain the renormalization of the quasiparticle residue Z, the Fermi velocity, and the curvature of the Fermi surface. We argue that the pairing is a BCS-type problem, but go one step beyond the BCS theory and calculate the critical temperature T_c with the prefactor. We apply the results to electron-doped cuprates near optimal doping and obtain T_c \geq 10 K, which matches the experimental results quite well.

description: We study the plasmon excitations and the electromagnetic response of the magnetically doped single layer and multilayer of ``helical metals'', which emerge at the surfaces of topological insulators. For the single layer case, we find a ``spin-plasmon'' mode with the rotating spin texture due to the combination of the spin-momentum locking of ``helical metals'' and the Hall response from magnetization. For the multilayers case, we investigate the electromagnetic response due to the plasmon excitations, including the Faraday rotation for the light propagating normal to the helical metal layers and an additional optical mode with the frequency within the conventional plasmon gap for the light propagating along the helical metal layers.

description: Objective: To investigate associations between obstructive sleep apnea (OSA) and readmission risk after hospitalization for asthma exacerbation. Methods: We conducted a retrospective, population-based cohort study using State Inpatient Databases from seven U.S. states (Arkansas, California, Florida, Iowa, Nebraska, New York, and Utah) from 2010 to 2013. We identified all adults (aged 18–54 years) hospitalized for asthma exacerbation. The outcome measure was all-cause readmissions within one year after hospitalization for asthma exacerbation. To determine associations between OSA and readmission risk, we constructed negative binomial regression models estimating the incidence rate ratio (IRR) for readmissions and Cox proportional hazards models estimating hazard rate (HR) for the time-to-first readmission. Results: Among 65,731 patients hospitalized for asthma exacerbation, 6,549 (10.0%) had OSA. Overall, OSA was associated with significantly higher incident rate of all cause readmission (1.36 vs. 0.85 readmissions per person-year; unadjusted IRR 1.60; 95%CI 1.54–1.66). Additionally, OSA was associated with higher incident rates of readmissions for five major diseases—asthma (IRR 1.21; 95%CI 1.15–1.27), COPD (IRR 2.03; 95%CI 1.88–2.19), respiratory failure (IRR 3.04; 95%CI 2.76–3.34), pneumonia (IRR 1.67; 95%CI 1.49–1.88), and congestive heart failure (IRR 3.78; 95%CI 3.36–4.24), compared to non-OSA. The Cox model demonstrated that patients with OSA had significantly higher rates for all-cause readmission compared to those without OSA (HR 1.56; 95% CI 1.50–1.62). These associations remained significant after adjustment for confounders. Conclusions: The observed association of OSA with a higher risk of readmissions after hospitalization for asthma exacerbation underscores the importance of identifying coexistent OSA in this population and optimizing both OSA and asthma management.

description: В настоящее время в сельском хозяйстве произошёл существенный перекос в сторону химических средств защиты растений. При этом не только почву, но и весь урожай активно «удобряют» нитратами и пестицидами. Такой подход к земледелию вредит не только здоровью населения, но и общему состоянию окружающей среды. Поэтому необходимо переходить к рациональному сочетанию агротехнических, биологических и химических методов борьбы с сорняками, вредителями и болезнями в посевах сахарной свёклы.
description: Currently, there has been a significant shift in agriculture towards chemical plant protection products. At the same time, not only the soil, but the entire crop is actively «fertilized» with nitrates and pesticides. This approach to farming is not only harmful to our health, but also to the general state of the environment. Therefore, it is necessary to move to a rational combination of agrotechnical, biological and chemical methods of controlling weeds, pests and diseases in sugar beet crops.
A new prediction of wavelength selection in radial viscous fingering involving normal and tangential stresses

description: We reconsider the radial Saffman-Taylor instability, when a fluid injected from a point source displaces another fluid with a higher viscosity in a Hele-Shaw cell, where the fluids are confined between two neighboring flat plates. The advancing fluid front is unstable and forms fingers along the circumference. The so-called Brinkman equations is used to describe the flow field, which also takes into account viscous stresses in the plane and not only viscous stresses due to the confining plates like the Darcy equation. The dispersion relation agrees better with the experimental results than the classical linear stability analysis of radial fingering in Hele-Shaw cells that uses Darcy's law as a model for the fluid motion.
