The efficient markets paradox: theoretical contributions of Steven C. Salop
Authors: Vargas Juliano
Published: May 2022

The purpose of this paper is to analyze Salop’s (1976) seminal proposal, in which the relevant market structure with imperfect information is not the one with perfect competition, but the one with monopolistic competition, with price dispersion. From the presentation of the perfect competition model, monopolistic competition model, Salop’s model and the main theoretical elements of this debate, alternative analyses based on studies of Akerlof and Grossman & Stiglitz are presented. In this regard, it will be shown that the results proposed by Salop, although considering the quality constant, are incompatible with the assumptions of neoclassical economics.

Educação profissional e educação de jovens e adultos na rede federal
Authors: Fernandes Irismar Severino da Silva , Lobão Mario Sérgio Pedroza , Freitas Renata Gomes de Abreu
Published: May 2022

O Programa Nacional de Integração da Educação Profissional com a Educação Básica, na Modalidade Educação de Jovens e Adultos (Proeja), acabou sendo uma junção da Educação Profissional e Tecnológica (EPT) com a Educação de Jovens e Adultos (EJA). Por isso, para entender o Proeja é imprescindível conhecermos anteriormente a EJA e a EPT. Esta pesquisa objetiva entender os itinerários das três modalidades de ensino na Rede Federal, tornando possível visualizar pontos de convergência e divergência, bem como compreender as nuances do Proeja. Para tanto, elegeu-se o método dialético, com abordagem qualitativa, de caráter exploratório do fenômeno investigado. A coleta de dados deu-se por meio de uma revisão bibliográfica e de uma análise documental. No ensejo, constatou-se que tanto a EJA quanto a EPT possuem históricos de marginalização, porém a segunda, ao adentrar em uma nova institucionalidade, teve as consequências do processo atenuadas, ao passo que a primeira permaneceu às margens das políticas educacionais. Por fim, verificou-se que o Proeja é um reflexo dessas duas realidades e, por isso, traz consigo a carga histórica desta e daquela, tendo sido implementado sem o planejamento necessário, o que sugerimos que corroborou para o processo de descontinuidade do programa na Rede Federal.
Crianças e adolescentes como sujeitos de conhecimento
Authors: Alves Hayda Josiane
Published: May 2022

O objetivo deste artigo é debater aspectos, relações e sentidos que limitam a participação de crianças e adolescentes na produção de saberes a partir da educação popular. Para tanto, somamo-nos à “crítica do saber” em torno da questionável neutralidade-objetividade das ciências, seus modos de legitimação e suas fronteiras para a participação infantojuvenil. Conceber as crianças e os adolescentes como seres de existência plena implica importantes desafios, visto que esses sujeitos tendem a ser negligenciados como seres de cultura, saber e educação, além de invisibilizados em escritos acadêmicos sobre suas famílias e suas comunidades. Além disso, nos processos de pesquisa, são subalternizados pela tutela do adulto como parte de uma regulamentação especial dos Comitês de Ética em Pesquisa voltada à proteção desse grupo, mas que acaba por silenciar suas vozes e comprometer sua autonomia. Torna-se fundamental aprofundar esse debate sob a perspectiva das epistemologias críticas e emergentes para além de um eixo ético-legal capaz de vislumbrar crianças e adolescentes como sujeitos plenos. Nesse caminho, as pedagogias freirianas possibilitam reflexões potentes ao reconhecer tais indivíduos como seres humanos em sua totalidade, capazes de criar e transformar saberes necessários à produção de conhecimento democrático.

Published: May 2022

O Conselho Local de Saúde é o órgão consultivo do SUS, na área da unidade local de saúde, relacionando-se diretamente ao Conselho Municipal de Saúde. O trabalho objetivou sistematizar a experiência de atuação em um Conselho Local de Saúde. Trata-se de um estudo descritivo com abordagem qualitativa fundamentado na sistematização de experiência. O instrumento utilizado para coleta de dados foi um diário de campo. As atividades se concentraram no desenvolvimento de oficinas voltadas para o controle social no SUS. O planejamento das atividades foi baseado em reflexões feitas enquanto participávamos das reuniões, que possibilitou identificar potencialidades e fragilidades do CLS. Ao final do processo sentimos uma equipe envolvida, comprometida com o conselho e com a busca de melhorias para a comunidade. Os encontros conseguiram desenvolver uma maior autonomia por parte dos conselheiros, a busca de um maior entendimento das necessidades da população, além de ser possível identificar uma maior disposição para mudança, onde observamos conselheiros mais empoderados sobre seu papel e suas responsabilidades. Dessa forma, entendemos que o processo educativo desenvolvido nesse espaço melhorou a qualidade da participação e fortaleceu o controle social.

O presente comentário de jurisrpdudência nasceu da analise da Opinião Consultiva OC 24/17 que foi proferido pela Corte Interamericana de Direitos Humanos sobre sua interpretação quanto aos temas “identidade de gênero, igualdade e não discriminação a casais do mesmo sexo, e quais as obrigações estatais em relação à mudança de nome, à identidade de gênero e aos direitos derivados de um vínculo entre casais do mesmo sexo” com base na Convenção Americana de Direitos Humanos. Assim, realizou-se uma análise dos argumentos utilizados e em consequência foram feitas sugestões argumentativas com objetivos de provocar o leitor a perceber novas perspectivas críticas para utilizar como argumentos.
Geração Distribuída e o Princípio da Segurança Jurídica
Authors: Dutra Vivenza Stefano , Matos Pedro
Published: May 2022

Este artigo busca analisar a expansão da Geração Distribuída no Brasil, tendo como ponto de partida a Resolução Número 482/2012 da Aneel, que regulamentou a implantação do Sistema de Compensação de Consumo de Energia Elétrica. Foi analisado o contexto da implantação do referido Sistema bem como os questionamentos que surgiram ao longo do tempo, que por sua vez geraram uma primeira Revisão do Sistema de Compensação e que no atual momento (2020) está em nova Revisão, sob intensa discussão e desafio de conciliar a expansão do sistema versus a manutenção ou não dos benefícios para os que a eles aderem. Foi discutida e analisada a proposta de alteração regulatória sob o prisma do principio da segurança jurídica. Ao final se verificou que a mudança na regulação de forma abrupta carrega consigo todas os indícios de uma violação ao princípio da segurança jurídica (por retroceder de forma mais gravosa, prejudicando investidores do setor) como também ao princípio constitucional da preservação do meio ambiente, pois tais alterações irão dificultar a expansão e até mesmo reduzir a prática da geração descentralizada no país, desestimulando uma conduta que está em plena conformidade com a ideia de desenvolvimento sustentável, uma vez que se mostrou muito mais eficaz e com menos degradação que a geração centralizada.

Published: May 2022

A pandemia do coronavírus veio ao mundo de forma abrupta e desmedida. A alta capacidade de transmissão do vírus e a necessidade de isolamento social, para os que puderam fazê-lo – visto a ausência de conhecimento de tratamento e prevenção adequados, colocou e coloca à mostra antigos problemas existentes mal resolvidos. Estruturas de opressão de gênero e do meio ambiente, antes mascaradas, hoje nos mostram como as dinâmicas sociais e produtivas devem ser repensadas. Nesse sentido, a partir de uma revisão bibliográfica propositiva, este artigo se propõe a fazer uma análise geral sobre a situação das mulheres e seus espaços de trabalho no contexto da pandemia, se propondo, ao final, formas paliativas e sistêmicas contra a situação.

proteção do consumidor como política global e regional
Authors: Lima Marques Claudia
Published: May 2022

Este artigo defende que a proteção internacional dos consumidores deve ser uma política global no século XXI, pois os consumidores são importantes atores da atual globalização econômica. Porém,  além das Diretrizes da ONU sobre Proteção ao Consumidor de 1985, revisadas em 1999 e 2015, e do Código Internacional de Proteção dos Turistas (UNWTO), de 2021, não existem outras regras mundiais ou globais (sejam instrumentos de soft ou de hard law) em matéria de proteção dos consumidores. Ao contrário do que acontece na área da proteção do meio abiente não há uma só convenção mundial ou instrumento vinculante sobre proteção do consumidor. Assim, parece imperioso agir regionalmente para proteger os consumidores, especialmente por meio de instrumentos jurídicos internacionais vinculantes. Este artigo analisa o papel do Mercosul no que diz respeito à promoção do direito internacional do consumidor, particularmente, os esforços do governo brasileiro para aprimorá-la dentro dessa organização econômica regional. Isso porque, o objetivo principal deste artigo é lançar luz sobre as atuais iniciativas regionais de proteção ao consumidor para confirmar a necessidade de outros instrumentos mais abrangentes e vinculants, especialmente em nível global, para que o autal quadro fragmentado da proteção do consumidor no mundo não crie disparidades que terminem por discriminar consumidores domiciliados em locais diferentes.

Authors: Gallego Henao Adriana María
Published: May 2022

El presente artículo de reflexión devela los resultados de una investigación cualitativa cuyo objetivo fue identificar tensiones e hitos que configuran el sistema educativo colombiano, y evidenciar los desafíos y retos que enfrenta el Gobierno Nacional en relación a las garantías básicas que favorezcan en la población infantil y juvenil el acceso y permanencia dentro del sistema escolar, aumentando los niveles de cobertura y disminuyendo los índices de repitencia. La metodología estuvo centrada en un paradigma cualitativo desde un enfoque interpretativo a partir de la identificación de las categorías teóricas como las trayectorias escolares (Promoción, repitencia, deserción, permanencia y asistencia) y las disposiciones legales a lo largo de los últimos años que han afectado las dinámicas del sistema educativo. Se concluye que es necesario comprender las trayectorias escolares desde los itinerarios, relatos, experiencias y significados que los estudiantes le asignan a su paso por la escuela.

This study was conducted to obtain salinity-tolerance Iraqi isolates of Pseudomonas fluorescence. Besides, test its salinity tolerance on PDA culture media and study its effect in the control of fusarium wilt disease on tomatoes caused by the fungus Fusarium oxysporum f.sp. lycopersici. Six isolates of bacteria were isolated from areas with soils showing symptoms of salinity, their potential for salinity tolerance was tested by three concentrations of NaCl (5, 10, and 15%). In addition to their antagonistic potential against the pathogenic fungus F. oxysporum f.sp. lycopersici isolate (FO3) was also tested on a PDA medium. The isolates PO1 and PO2 were selected, which showed the potential to salinity tolerate at different concentrations of salt and the most growth-inhibiting of the pathogenic fungus F. oxysporum f.sp. lycopersici. The two isolates were partially identified using the PCR technique, and the sequence was deposited in the NCBI global gene bank, they were given Accession No. (ON041212 and ON041213). The two isolates' effect in controlling fusarium wilt on tomato plants showed efficiency in reducing the rate and severity of wilt disease. Thus, the incidence reached (13.33-85.00%) and the disease severity (10.34-80.00%) respectively, compared to the control treatment (without pathogenic fungi), which showed the incidence and disease severity amounted to (90.00 - 93.33%). Moreover, the treatment of inducing resistance showed high effectiveness with significant differences among all treatments in reducing the incidence and disease severity amounted to (10.34 - 13.33%).

Distinct morphology of cardiac‐ and brown adipose tissue‐projecting neurons in the stellate ganglia of mice
Authors: Barrett Madeleine S. , Hegarty Deborah M. , Habecker Beth A. , Aicher Sue A.
Published: May 2022

Sympathetic neurons that innervate the heart are located primarily in the stellate ganglia (SG), which also contains neurons that project to brown adipose tissue (BAT). These studies were designed to examine the morphology of these two populations (cardiac‐ and BAT‐projecting) and their target connectivity. We examined SG neurons in C57BL/6J mice following injections of the retrograde tracer cholera toxin B (CTb) conjugated to Alexa Fluor 488 and Alexa Fluor 555, into cardiac tissue and intrascapular BAT. BAT‐projecting SG neurons were widely dispersed in SG, while cardiac‐projecting SG neurons were localized primarily near the inferior cardiac nerve base. SG neurons were not dual‐labeled, suggesting that sympathetic innervation is specific to the heart and BAT, supporting the idea of “labeled lines” of efferents. Morphologically, cardiac‐projecting SG somata had more volume and were less abundant than BAT‐projecting neurons using our tracer‐labeling paradigm. We found a positive correlation between the number of primary dendrites per neuron and soma volume in cardiac‐projecting SG neurons, though not in BAT‐projecting neurons. In both SG subpopulations, the number of cholinergic inputs marked with vesicular acetylcholine transporter (VAChT) puncta contacting the soma was positively correlated to soma volume, suggesting scaling of inputs across a range of neuronal sizes. In separate studies using dual tracing from left and right BAT, we found that BAT‐projecting SG neurons were located predominately ipsilateral to the injection, but a small subset of SG neurons project bilaterally to BAT. This tracing approach will allow the assessment of cell‐specific mechanisms of plasticity within subpopulations of SG neurons.
The Decline of Substance over Form in Accounting: A Problematic Dichotomy
Authors: Williams Paul F.
Published: May 2022

This essay is a comment on the paper authored by Fischer, Ellman and Schocet (2021, The decline of substance over form in accounting. Accounting, economics, and law: A convivium. (2023)) who argue that the trend in financial reporting regulation involves de-emphasizing the important of economic substance relative to form in how auditors are to perceive their role. The danger foreseen by the authors is the further shrinking of the leeway for professional judgment, which is an important hallmark of a true professional. Agreeing the authors have raised a crucial issue for any group claiming professional status, I try to add to the discussion by pointing out that form and substance in the realm of financial reporting regulation are not antipodes but complementary parts of a process of continuous redefining of what economic substance is. Social reality is socially constructed and as such choices of form made by humans effectively shape substance. Given the capture of accounting by economics during the 1960s, accountants have lost an appreciation for the tentativeness of economic substance and now serve not as participants in shaping economic substance but as enforcers of an imaginary economic substance that derives from the assumptions and values in the ideology of neoclassical economics.
Umbilical artery aneurysm without aneuploidy and delivery of a live neonate
Authors: Lewis Gregory K. , Dawkins Josette C. , Tang Xiangna
Published: May 2022

Objectives

Umbilical artery aneurysm, a rare structural anomaly of the umbilical cord, is frequently associated with fetal aneuploidy, fetal growth restriction and fetal demise. At present there are no definitive protocols or guidelines for the surveillance and management of this condition.

Case presentation

The index case is an 18-year-old primigravida who had an ultrasound at 35 weeks and 5 days gestation due to lagging symphysio-fundal height measurement. The ultrasound scan revealed a normal fetus with estimated fetal weight that was appropriate for gestational age. There was a cystic structure with internal echoes originating from the placenta at the point of the umbilical cord insertion, which was determined to be a 1.9 × 1.8 cm umbilical artery aneurysm on 3D and Doppler imaging. On follow up imaging the aneurysm had increased in size and measured 3.06 × 1.79 cm. The patient subsequently had a cesarean section delivery of a live female. Karyotyping subsequently revealed 46 XX.

Conclusions

A total of 15 cases of umbilical artery aneurysm have been reported in the literature to date, of which there were 5 live born infants with normal karyotype. The remaining 10 cases were intra-uterine fetal demise or trisomy 18 with subsequent neonatal deaths. When monitoring the aneurysms with ultrasound, change in size and Doppler indices play a pivotal role in helping to determine time and mode of delivery and thus allow for a favorable perinatal outcome.
Persistence landscapes of affine fractals
Authors: Catanzaro Michael J. , Przybylski Lee , Weber Eric S.
Published: May 2022

We develop a method for calculating the persistence landscapes of affine fractals using the parameters of the corresponding transformations. Given an iterated function system of affine transformations that satisfies a certain compatibility condition, we prove that there exists an affine transformation acting on the space of persistence landscapes, which intertwines the action of the iterated function system. This latter affine transformation is a strict contraction and its unique fixed point is the persistence landscape of the affine fractal. We present several examples of the theory as well as confirm the main results through simulations.
Collective Narcissism and Perceptions of the (Il)legitimacy of the 2020 US Election
Authors: Federico Christopher M. , Farhart Christina , Vitriol Joseph , Golec de Zavala Agnieszka
Published: May 2022

Recent work suggests that collective narcissism—an exaggerated, unrealistic belief in an in-group’s greatness that demands constant external validation—is a reliable predictor of authoritarian-populist hostility toward democratic norms, processes, and outcomes. In the present study, we use a recent survey of American adults to examine the relationship between collective narcissism and perceptions that the 2020 election in the US was illegitimate. We find evidence that those high in national collective narcissism are more likely to endorse a number of beliefs about the illegitimacy of the 2020 US election, including greater perception of fraud, procedural unfairness, and inaccurate vote counting. Importantly, we find that this relationship is strongest among those whose identities were most threatened by a loss of power due to the 2020 presidential outcome, i.e., Republicans and conservative identifiers.
The prevalence of and risk factors for stillbirths in women with severe preeclampsia in a high-burden setting at Mpilo Central Hospital, Bulawayo, Zimbabwe
Authors: Ngwenya Solwayo , Jones Brian , Mwembe Desmond , Nare Hausitoe , Heazell Alexander E.P.
Published: May 2022

Objectives

Stillbirth remains a global public health issue; in low-resource settings stillbirth rates remain high (>12 per 1,000 births target of Every Newborn Action Plan). Preeclampsia is major risk factor for stillbirths. This study aimed to determine the prevalence and risk factors for stillbirth amongst women with severe preeclampsia at Mpilo Central Hospital.

Methods

A retrospective cross-sectional study was conducted of women with severe preeclampsia from 01/01/2016 to 31/12/2018 at Mpilo Central Hospital, Bulawayo, Zimbabwe. Multivariable logistic regression was used to determine risk factors that were independently associated with stillbirths.

Results

Of 469 women that met the inclusion criteria, 46 had a stillbirth giving a stillbirth prevalence of 9.8%. The risk factors for stillbirths in women with severe preeclampsia were: unbooked status (adjusted odds ratio (aOR) 3.01, 95% (confidence interval) CI 2.20–9.10), frontal headaches (aOR 2.33, 95% CI 0.14–5.78), vaginal bleeding with abdominal pain (aOR 4.71, 95% CI 1.12–19.94), diastolic blood pressure ≥150 mmHg (aOR 15.04, 95% CI 1.78–126.79), platelet count 0–49 × 109/L (aOR 2.80, 95% CI 1.26–6.21), platelet count 50–99 × 109/L (aOR 2.48, 95% CI 0.99–6.18), antepartum haemorrhage (aOR 12.71, 95% CI 4.15–38.96), haemolysis elevated liver enzymes syndrome (HELLP) (aOR 6.02, 95% CI 2.22–16.33) and fetal sex (aOR 2.75, 95% CI 1.37–5.53).

Conclusions

Women with severe preeclampsia are at significantly increased risk of stillbirth. This study has identified risk factors for stillbirth in this high-risk population; which we hope could be used by clinicians to reduce the burden of stillbirths in women with severe preeclampsia.
Evaluating the Growth Assessment Protocol for stillbirth prevention: progress and challenges
Authors: Butler Emily , Hugh Oliver , Gardosi Jason
Published: May 2022

Many stillbirths are associated with fetal growth restriction, and are hence potentially avoidable. The Growth Assessment Protocol (GAP) is a multidisciplinary program with an evidence based care pathway, training in risk assessment, fetal growth surveillance with customised charts and rolling audit. Antenatal detection of small for gestational age (SGA) has become an indicator of quality of care. Evaluation is essential to understand the impact of such a prevention program. Randomised trials will not be effective if they cannot ensure proper implementation before assessment. Observational studies have allowed realistic evaluation in practice, with other factors excluded that may have influenced the outcome. An award winning 10 year study of stillbirth data in England has been able to assess the effect of GAP in isolation, and found a strong, causal association with improved antenatal detection of SGA babies, and the sustained decline in national stillbirth rates. The challenge now is to apply this program more widely in low and middle income settings where the main global burden of stillbirth is, and to adapt it to local needs and resources.
Multimodal instructional communication in science and engineering in two university classrooms
Authors: Sharma Bal Krishna
Published: May 2022

Universities in English speaking countries have been witnessing an increasing number of international faculty who speak English as an international language. However, the universities are mostly guided by the dominant monolingual ideologies and language policies that favor verbal repertoires in standard English even though instructional communication is characteristically multimodal. Against this backdrop, this article focuses on two faculty members in STEM and investigates their instructional interaction. Using multimodal interaction as a theoretical and methodological heuristic, the analysis pays attention to how modes, codes and material objects are ensembled in specific configurations as instructors and students engage in the process of meaning negotiation. The instructors’ instructional practices and perspectives demonstrate the importance of the entanglement of language with diverge semiotic, social and material elements of communication. The findings suggest a need for a broader definition and scope of instructional interaction in STEM.
Enhancement of thermal conductivity in polymer composites by maximizing surface-contact area of polymer-filler interface
Authors: Kumar Vijendra , Barnwal Abhishek , Shukla Rajesh K. , Shakya Jyoti
Published: May 2022

In this article we discuss in detail the effective approaches to enhance the thermal conductivity in polymer composites. Numerical simulations show that maximizing interfacial area between filler and polymer enhances very significantly the effective thermal conductivity in composites. We show that among the different geometries thermal conductivity is high for those geometries for which the ratio of surface-area to volume is high. For fillers of a particular geometry, by maximizing its surface area without changing the volume fraction of the metallic filler, the effective thermal conductivity increases. Thus, the interfacial area between filler and polymer plays an important role in the enhancement of thermal conductivity. It is also observed that as this interfacial area increases, increase in effective thermal conductivity follows from linear to the logarithmic growth. It should be noted that to inherit the polymer properties there is a restriction on the upper bound of volume fraction of the fillers. The current study brings out an important step in this direction. Our results are technologically very important in designing composite polymers for better heat conduction and are very cost-effective. This study also provides a connection between the bulk and the surface area in effective determination of the thermal conductivity.
Metal-mediated C–C bond formation in a platinum(II)-coordinated dipyridylmethane ligand: an unusual example of “ipso-coupling” with solvent involvement
Authors: Sommerfeld Nadine S. , Gülzow Jana , Kohl Julia , Grohmann Andreas
Published: May 2022

We report the chelation-assisted oxidative CH2 extrusion from a PtII-coordinated dipyridylmethane, resulting in the formation of a 2,2′-bipyridyl ligand. This unusual one-pot reaction (solvent: dimethylformamide, DMF), which is quantitative, proceeds in air at mildly elevated temperature, with CH2 → C=O conversion, decarbonylation, and ipso-ipso C–C coupling of the two pyridyl residues (“fragment coupling”). It constitutes, in effect, a chelate ring contraction by one member.
THE NEW GOVERNMENT OF GERMANY AND GERMAN-RUSSIAN RELATIONS. UKRAINIAN FACTOR. PART 2
Authors:   Institute of Europe, Russian Academy of Sciences, Belov Vladislav
Published: May 2022

The recognition by the Russian Federation of the independence of the Donetsk and Lugansk People’s Republics, the following announcement by the President of the Russian Federation of a special military operation in connection with the situation in the Donbass in order to protect the citizens of the DPR and LPR, as well as the demilitarization and denazification of Ukraine, caused a sharp negative reaction from all political forces and strata of society in Germany. Its executive and legislative power has become the main protagonist of the five sanctions packages adopted by the European Union against the Russian Federation and which affected almost all areas of the national economic complex. A large-scale anti-Russian campaign was launched in the German media, actively supported by the Ukrainian leadership. This development of events marked the entry into a qualitatively new phase of relations between Germany and Russia. To predict such beginning of mid-February this year was impossible. Therefore, in the first part of our article, devoted to the Russian vector of the new governing coalition, relatively optimistic assessments were made. In the second part, the author examines this vector under new conditions, analyzes the most important anti-Russian steps and measures taken by the German cabinet of ministers and the Federal Chancellor. Particular attention is paid to the reaction of German business to the situation in Ukraine. The author evaluates their consequences for political and economic spheres of bilateral relations. In conclusion, a forecast of their further development is given. The third part of the article will analyze the consequences of the Ukraine crisis for science, education and culture.
THE MUSLIM BROTHERHOOD IN EUROPE: BETWEEN RELIGION AND POLITICS. PART 2
Authors:   Institute of Europe, Russian Academy of Sciences, Shumilin Aleksandr

In this article, the author considers two most important, in his opinion, aspects of the activities of the Islamist movement «Muslim Brotherhood» (MB) in Europe today – a rupture that has emerged in the system of the highest governing bodies of the MB (the formation of two rival centers – in Istanbul and London) and the intensification of attempts of MB groups participation in the political life of European countries under the «banner of Islam». The author draws attention to the fact that the observed «renaissance of the brothers» in Europe not only clearly contrasts with the position of their associates in most Arab countries, in whose social and political life they are failing after failure, but can also be considered as an attempt to lead the MB precisely through his European experience to preserve the movement itself, to support the dynamics of its activity, to formulate its upcoming goals. In other words, to demonstrate the ability of the movement and its ideology to transform and adapt to the conditions of the 21st century. To do this, the Islamist «brotherhood» is actively exploiting the potential of the welfare state and political freedoms in the Old World. The author explores the mechanisms used by the Islamists of the BM to penetrate into state structures and influential layers of European societies. It is noteworthy that the activities of the MB are increasingly mentioned by European experts and politicians in the context of growing internal threats to their countries.

The present paper reports the elastic, mechanical and thermophysical properties of silver nanowire (Ag NW) using ultrasonic techniques at temperature dependent. Higher order elastic constants are calculated using Coulomb and Born-Mayer potential up to second nearest neighbour. To compute mechanical parameters such as young modulus, bulk modulus, shear modulus tetragonal modulus, Poisson's ratio, fracture to toughness ratio and Zener anisotropy factor for finding imminent performance of the single silver nanowire at temperature dependent using second order elastic constants. The Ag NW is found to be brittle in nature at room temperature. Finally, we have evaluated the ultrasonic velocities, ultrasonic attenuation due to phonon–phonon interaction and thermoelastic relaxation for longitudinal wave and shear waves along <100>, <110> and <111> crystallographic directions in the temperature range 100-300K of silver nanowire using the higher order elastic constants. The attained results are discussed in correlation with available outcomes on these properties for the silver nanowire.

AbstractThis research explains a comparison estimation for AUV position using Kalman Filter (KF), Ensemble Kalman Filter (EnKF), and Fuzzy Kalman Filter (FKF) algorithm in some specified trajectories. Estimation is developed for AUV Segorogeni ITS which was built by the Institute Technology of Sepuluh Nopember (ITS), Indonesia. The specified trajectories are the diving, straight, and turning path which is the real trajectories. We compare the result estimation for each of the trajectories from the simulation and the RMSE (Root Mean Square Error). In this case, the best estimation is given by the difference estimation method. Fuzzy Kalman Filter gives the best result for the diving trajectory (Y-position and angle) and the straight trajectory. Ensemble Kalman Filter (EnKF) gives the best result for the X-position in the diving trajectory. While Kalman Filter gives the best result for the straight trajectory.Keywords: AUV; Kalman Filter (KF); Ensemble Kalman Filter (EnKF); Fuzzy Kalman Filter (FKF); AUV Segorogeni ITS. AbstrakPenelitian ini menjelaskan tentang perbandingan estimasi untuk posisi AUV antara algoritma Kalman Filter (KF), Ensemble Kalman Filter (EnKF) dan Fuzzy Kalman Filter (FKF) untuk trayektori tertentu.

Stability Analysis of Leslie-Gower Model with Herd Behavior on Prey
Authors: Dwi Putra M. Adib Jauhari , Himayati Ade Ima Afifa
Published: May 2022

AbstractWe studied the Leslie-Gower model of predator-prey with herd behavior. The square root functional response models predator and prey interactions that show herd behavior. This study aims to determine the formulation of the predator-prey model with herd behavior on prey, knowing the fixed points and its stability and simulating the model numerically. We found three fixed points that may exist: the extinction point of both species, the extinction of predator point, and the point of coexistence of the two species. The extinction of predator points is always unstable, while the point of coexistence of the two species can be stable under certain conditions. Due to the presence of square roots, the behavior of the solutions near the extinction point of the two species is not readily apparent. Numeric simulation shows that changing the initial condition and parameters can change the system's stability.Keywords: predator-prey; functional response; herd behavior; square root functional response, Leslie-Gower model. AbstrakArtikel membahas model predator prey Leslie-Gower dengan perilaku bergerombol pada prey. Interaksi predator dan prey yang menunjukkan perilaku bergerombol dimodelkan dengan fungsi respon akar kuadrat. Penelitian ini bertujuan untuk mengetahui formulasi model predator-prey dengan perilaku bergerombol pada prey, mengetahui titik ekuilibrium dan kestabilannya serta menyimulasikan model tersebut secara numerik. Hasil menunjukkan terdapat tiga titik tetap yang mungkin eksis, yaitu titik kepunahan kedua spesies, titik kepunahan predator dan titik koeksistensi kedua spesies. Titik kepunahan predator selalu tidak stabil, sedangkan titik koeksistensi kedua spesies bisa stabil dengan syarat tertentu. Karena adanya akar kuadrat, perilaku solusi di dekat titik kepunahan kedua spesies tidak mudah terlihat. Simulasi numerik menunjukkan bahwa perubahan nilai awal dan parameter dapat mengubah kestabilan sistem.Kata Kunci: predator prey; fungsi respons; perilaku bergerombol; fungsi respon akar kuadrat; model Leslie-Gower.
