Human Rights, Native Lands and Environmental Issues: The Demise of Mother Nature and of the Indigenous Peoples of Brazil
Authors: Santos Marlei Angela Ribeiro dos , Wenczenovicz Thais Janaina , Linhares Émelyn
Published: May 2022

The aim of this paper is to analyze the historical trajectory of demarcations of Brazil’s traditional lands, as well as the rights and emergent violence concerning this issue. The choice of this topic is justified by the constant violation of the demarcation rights of indigenous lands, the lag in administrative processes, or judicial decisions and bills that do not acknowledge or hamper these rights, as well as the effects of this oversight on the life and demise of indigenous peoples and on nature. The method used was bibliographical-investigative through the use of data from the Social-environmental Institute, the Indigenous Missionary Council, national and international court of laws and current legislation. First, a reflection on the identitary and personal construction of Amerindians is carried out; followed by an analysis of the development of colonialism in Brazil through its effect on traditional territories and peoples; and, finally, numbers and consequences regarding the life and demise of indigenous peoples and the environment are discussed. State negligence concerning the demarcation of these lands is confirmed, as well as the occurrence of violations and violence towards native peoples, along with scarce environmental protection. There is a need for the evolution and reconstruction of concepts and of the legal framework within a decolonial perspective, in order for the full-fledged recognition of indigenous peoples’ rights to take place.

Published: May 2022

Hydrocephalus is a pathology characterized by the accumulation of cerebrospinal fluid (CSF) in the cerebral ventricles (intercommunicating cavities located in areas of the brain) and in the subarachnoid space between the arachnoid and pia mater membranes of the meninges. The aim of this study was to present a review of the literature, with a contemporary character, on Hydrocephalus and its implications on the central nervous system. The present research was carried out during the years 2018 to 2022 through a search of the keywords in the descriptors in Health Science (DECS) and were added in the databases: VHL (Virtual Health Library), Google Scholar, LILACS, PubMed, Scielo. In total, 08 (nine) articles were used as primary search and 33 (thirty-three) articles as secondary search. The titles of the articles included in the present study were those that presented a direct correlation with the keywords, articles up to 05 (five) years old or classic authors of the theme even with a later date. Bibliographic data, such as electronic journals and websites that clearly explain hydrocephalus. Through the analysis of the bibliographic data that were studied, it was noticed that the head of the patient with hydrocephalus suffers more visibility when talking about anatomical structure, and sequelae regarding the Central Nervous System.
Nonlinear analysis of reinforced concrete slabs through the finite element method
Authors: Viegas Carlos Henrique Hernandorena , Real Mauro de Vasconcelos , Titello Eduardo Pagnussat
Published: May 2022

One of the significant difficulties in representing the behavior of reinforced concrete structures in mathematical models is the post-cracking non-linearity. And so, reinforced concrete slabs are no exception to the rule. Still, the usual analysis models for this structural element are verified in the elastic regime when the concrete tensile strength is considered. This model is acceptable for the service limit states but not the ultimate limit state. These aspects associated with the great difference in the behavior of concrete when subjected to tension or compression make it necessary to study a nonlinear mathematical model that can represent a reinforced concrete slab subjected to bending, from the beginning of loading until its failure, as accurately as possible. With this, the ANSYS software, from its version 18, made available in its library the Drucker-Prager-Rankine model arranged with two distinct rupture surfaces. A Drucker-Prager criterion for the concrete subjected to compression and a Rankine criterion for concrete in tension. In addition, the software is based on the finite element method, giving the possibility of precise and nonlinear analysis through load and deformation increments, taking into account both elastic and plastic deformations after concrete cracking. Thus, this work aims to present the modeling of reinforced concrete slabs through the Drucker-Prager-Rankine surface, validating the model by comparing it with several experimental tests. The model results were coherent and acceptable, presenting a good approximation of the results of the tests.
The use of Electronic Dictionary Strategies among English as a Foreign Language (EFL) Learners
Authors: Tran Phi The , Mai Viet Hoang
Published: May 2022

It is true that dictionaries have played an indispensable role in the process of language acquisition, and in the case of EFL learning, this is not an exception. However, in Vietnam, there have not been many studies, research, and materials exploring the use of electronic dictionaries (EDs) as well as instructing EFL learners to employ them effectively. Hence, the aim of this paper is to investigate EFL learners’ use of electronic dictionary (ED) strategies at an English center in Ho Chi Minh City, Vietnam. The study involved 98 EFL learners who were asked to complete the given questionnaire. The quantitative data were analyzed by SPSS to extract their mean, standard deviation, and frequency. The results indicated that the EFL participants only made use of an average number of ED strategies. It is hoped that these introductory findings can be beneficial for other researchers in their studies related to dictionary use as well as providing potential ideas for EFL teachers who want to implement dictionary training into their lessons.
Poiein and Infinite Identity: A Meta-critical Inquiry into Marginality
Authors: C Rafid
Published: May 2022

The paper argues that the theoretical ‘definitions’ of marginality assume a fixed essence to the experience of marginality. And such definitions necessarily contradict the experience of marginality: the social experience as well as the experience performed in literature. The paper traces the evolution of different theories of marginality to locate the inherent contradictions caused by the mismatch between theory and experience. Following that, the paper explores the representations of marginality in S Hareesh’s novel Meesha (Moustache (2018)) in the Malayalam language. The protagonist Vavachan belongs to a lower caste community and he often violates the caste equations and terrorises the social order with his uncanny appearance. This reading consequently shows that the literary experience of marginality does not ‘fit’ to a framework that theorises the ‘marginal’ as a finite category, and it necessitates a new framework to understand the 'marginal’ as well as the dynamic relation between the margin and the centre. To accommodate the dynamic nature of the centre-margin relations, we need a formative critical framework that changes itself when it encounters a new possibility of centre-margin relations. The critical framework is perpetually formative in relation to new readings and experiences; such a framework transcends all predetermined models of centre-margin relations in a community. Jean-Luc Nancy adopts a similar approach in his work The Inoperative Community (1986). According to him, the predetermined conception of society as an ‘essence’ or constituted in an essence leads to the ‘closure of the political’. Admitting the lack of an ‘essence’, the framework becomes open to differences and nuances of the experiences. The departure from ‘essence’ is also the departure from the theoretical fixities. In contextualising this idea in literary criticism, the primary inspiration of my paper is Stathis Gourgouris’ conceptualisation that critical frameworks are in ‘poiein’ state. The framework is always in a perpetual reworking or ‘in the making’ state and never finite. By incorporating the ‘infinite identity’ of the community within a ‘poiein’ mode of criticism, my paper attempts to forge a new critical framework that understands the dynamic nature of the centre-margin relations.

Abstract: Sentiment analysis has become a stimulating field for both research and industrial domains. The expression sentiment refers to the emotions or thought of the person across some certain issues. Furthermore, it's also considered an immediate application for opinion mining. the large amount of tweets jotted down daily makes Twitter an upscale source of textual data and one among the foremost essential data volumes; therefore, this data has different aims, like business, industrial or social aims consistent with the info requirement and needed processing. Actually, the quantity of knowledge , which is very large , grows rapidly per second and this is often called big data which needs special processing techniques and high computational power so as to perform the specified mining tasks. during this work, we perform a sentiment analysis with the assistance of PySpark framework, an interface for Apache Spark in Python which is taken into account an open source distributed processing platform which utilizes distributed memory abstraction. The goal of using PySpark is that we can run applications parallelly on the distributed cluster (multiple nodes). The effectiveness of our proposed approach is proved against other approaches achieving better classification results when using Naïve Bayes, Logistic Regression and Decision trees classification algorithms. Finally, our solution estimates the performance of Apache Spark concerning its scalability. Keywords: Python, Pyspark, Machine learning, tweepy, tokenization.

Abstract: The rocker- dread suspense system has robust capabilities to deal with uneven terrain because of its distributing of the cargo over its six bus slightly, while there's one major failing to high- speed traversal over the planar terrain. This paper proposes a new dynamic rocker- dread suspense system with two modes of operation it can expand the span of the rocker- dread support polygon to increase trip rate when the terrain is planar; and it can switch to its original configuration to move in low speed when it's faced with rough terrain. The analysis on dynamic stability periphery and kinematical simulation on the two operating modes of rocker- dread are employed to dissect and corroborate the rationality and effectiveness of the revision in the structure.

Along these lines there emerges a need to build up a choice emotionally supportive network for identifying heart problems of a patient. In this paper, we propose effective hereditary calculation half breed with machine learning approach for heart disease expectation. Today clinical field have made considerable progress to treat patients with different sort of infections. To accomplish a right and practical treatment and emotionally supportive networks can be created to settle on great choice. Numerous emergency clinics use clinic data frameworks to deal with their medical services or patient information. These frameworks produce gigantic measures of information as pictures, text, outlines and numbers. Tragically, this information is seldom used to help the medical growth. There is a greater part of concealed data in this information that isn’t yet investigated which offer ascent to a significant inquiry of how to make valuable data out of the information. So there is need of making an incredible venture which will assist experts with anticipating the heart issues before it happens. The principle objective of this paper is to build up a model which can decide and extricate obscure information related with heart problems from a past heart information base record. It can tackle muddled questions for recognizing heart disease and subsequently help clinical experts to settle on savvy clinical decision.

Application of the G.A. Geniev, N.S. Chausova method for stability of shallow shells investigation
Authors: Kolesnikov Alexander G. , Spasskikh Ivan A.
Published: May 2022

Introduction. The work is devoted to the stability of shallow shells investigation, based on the G.A. Geniev, N.S. Chausov methodology. An analysis is given of the works of the authors working on the issues of determining the stress-strain state of this structure type. Current trends and shortcomings of the methods used are indicated.

Materials and methods. The analysis of stability is based on the G.A. Geniev, N.S. Chausov fundamental work. It defines the first and second kind stability lost and substantiates the use of an equations system to describe the stress-strain state of a structure. The equations system for shallow shells with constant and variable thickness and shape of the middle surface is solved using the Bubnov – Galerkin method. The approximating functions of stresses and displacements make it possible to vary the type of structure support.

Results. Implementation of the G.A. Geniev and N.S. Chausov methodology with V.Z. Vlasov approximating functions made it possible to investigation the influence of various parameters on the critical load. The geometric nonlinearity of the work of structures was taken into account. Specific values of the design parameters are given, which increase the second kind stability with constant initial data.

Conclusions. The analysis of the shallow shells stability made it possible to reveal the regularities in the change in the value of the critical load when varying various geometric characteristics. The presented results can be used in the design of real structures. At the same time, it is possible to set the tasks of optimizing such structures with restrictions on the value of their volume (weight) or minimizing it due to the interconnected change in geometric characteristics while maintaining the bearing capacity.

Authors: Konovalov Mikhail A. , Kozinets Galina L.
Published: May 2022

Introduction. The idea of building wooden multi-storey buildings in Russia is becoming more and more relevant every year. The emergence of new technologies makes this area of construction promising. The purpose of the article is to illustrate the stages of design, which will contribute to the successful development of projects of multi-storey buildings, where wood is used as the main material of load-bearing structures. As a confirmation of the correctness of these algorithms, the results are demonstrated.

Materials and methods. For a general representation of the stages of construction of this type of objects, an algorithm for their design is given, which allows to streamline the process of selecting structural elements, to focus on the key points of the design process, which ultimately facilitates the complexity of designing this kind of structures. The use of wooden components made of CLT, LVL and glued wooden columns is proposed as bearing elements. Calculations of structures were carried out taking into account the software package in compliance with the current regulatory documentation.

Results. After analyzing the key aspects according to the developed algorithm, it is necessary to proceed to solving the main issue of the development of the building’s load-bearing system. The creation of the model in question was carried out using three-dimensional design software products, followed by calculations by Autodesk Robot Structural. With the help of the calculation program, the results of bending and internal stresses were obtained. Based on the results of calculations of the load-bearing structural elements, a comparative analysis of the load-bearing characteristics in various types of structural systems was performed.

Conclusions. Thanks to the competent study of key issues at the initial stages of design, it is possible to achieve a balanced model of a multi-storey wooden building, which is successfully implemented by builders.
Determination of elastic characteristics of cement stone to predict the fatigue life of concrete
Authors: Kurbatov Yuri E. , Kashevarova Galina G.
Published: May 2022

Introduction. The problem of fatigue failure of concrete is one of the least studied in computational practice. The lack of reliable data on the actual processes of accumulation of fatigue damage occurring in the structure of this material during cyclic exposure does not allow us to form a methodology for calculating concrete structures that perceive such loads. To develop the above methodology, it is proposed to use structural simulation modeling. For this purpose, mathematical models of concrete damage under the influence of cyclic loading are considered. The purpose of the study is to determine the elastic and strength characteristics of cement stone for further development of a methodology for predicting the fatigue life of concrete, taking into account the nonlinear kinetics of damage accumulation.

Materials and methods. The strength limits of cement stone during bending and compression were determined by conducting a full-scale experiment on a testing machine and a hydraulic press. Elastic characteristics of cement stone were obtained as a result of static tests of cement stone samples of various shapes on the universal electromechanical system with the joint use of the digital optical system for analysis of deformation and displacement fields and the acoustic emission signal recording system.

Results. During the tests of cement samples for bending and compression, the values of the corresponding bending and compression strength limits were obtained, which made it possible to confirm the design strength class of cement 32.5 N. Inhomogeneous fields of longitudinal and transverse deformations were obtained using a digital optical system to further determine the basic elastic characteristics of the material. Obtaining acoustic emission signals during the experiment made it possible to reflect the dependences of various acoustic emission parameters on time.

Conclusions. The first stage of the proposed methodology for predicting the fatigue life of concrete is performed, taking into account the nonlinear kinetics of damage accumulation, as a result of which the modulus of elasticity and the Poisson’s ratio for cement stone are determined. The obtained data can be used to create a numerical model of the concrete structure, and the use of acoustic emission signals allows us to estimate the kinetics of damage accumulation in the material.
Indícios de aparelhamento psicológico em artigos acadêmicos de pediatria e administração
Authors: Aragão Rodrigo Moura Lima de
Published: May 2022

A teoria do aparelhamento ou primação lexical formulada pelo professor e pesquisador britânico Michael Hoey (Lexical priming: A new theory of words and language; Abingdon, UK: Routledge, 2005) propõe que a configuração das línguas resulta de processos mentais individuais alimentados por encontros entre indivíduos e palavras. Conforme a teoria, experiências prévias preparam, aparelham ou primam os usuários das línguas a empregar certas palavras e outros recursos linguísticos em determinados contextos, domínios e gêneros textuais. Este trabalho teve como objetivo explorar a relação entre aparelhamento psicológico (psychological priming) – elemento central da teoria – e variação disciplinar, com foco na escrita acadêmica em português. Para tanto, foram compilados dois corpora especializados. O primeiro é composto por 24 artigos publicados na Revista Paulista de Pediatria; o segundo, por 24 artigos da Revista de Administração de Empresas. Com o auxílio de ferramentas de programas de análise linguística, foram estudados aspectos colocacionais, semânticos e distributivos de duas palavras-chave comuns a ambos os corpora: estudo e pesquisa. Como resultado, observaram-se diferenças entre os dados de pediatria e administração. Todavia, ao passo que as diferenças relativas a pesquisa são bem marcadas, as diferenças relativas a estudo são um pouco mais sutis. Os resultados mostram a relevância do fator campo de conhecimento ou disciplina para o aparelhamento psicológico de autores de artigos acadêmicos em língua portuguesa. Ainda, indicam a existência de palavras mais e menos propensas a assumir comportamentos distintos em disciplinas diversas.

We consider Cauchy problem for ordinary differential equation with solution possessing a sequence of multiple poles. We propose the generalized reciprocal function method. It reduces calculation of a multiple pole to retrieval of a simple zero of accordingly chosen function. Advantages of this approach are illustrated by numerical examples. We propose two representative test problems which constitute interest for verification of other numerical methods for problems with poles.

Published: May 2022

Mathematical statement of one-wavelength antireflective coating based on two-dimensional metamaterial is formulated for the first time. The constraints on geometric parameters of the structure are found. We propose a penalty function, which ensures the applicability of physical model and provides the uniqueness of the desired minimum. As an example, we consider the optimization of metasurface composed of PbTe spheres located on germanium substrate. It is shown that the accuracy of the minimization with properly chosen penalty term is the same as for the objective function without it.
Multistage pseudo-spectral method (method of collocations) for the approximate solution of an ordinary differential equation of the first order
Authors: Lovetskiy Konstantin P. , Kulyabov Dmitry S. , Hissein Ali Weddeye
Published: May 2022

The classical pseudospectral collocation method based on the expansion of the solution in a basis of Chebyshev polynomials is considered. A new approach to constructing systems of linear algebraic equations for solving ordinary differential equations with variable coefficients and with initial (and/or boundary) conditions makes possible a significant simplification of the structure of matrices, reducing it to a diagonal form. The solution of the system is reduced to multiplying the matrix of values of the Chebyshev polynomials on the selected collocation grid by the vector of values of the function describing the given derivative at the collocation points. The subsequent multiplication of the obtained vector by the two-diagonal spectral matrix, inverse with respect to the Chebyshev differentiation matrix, yields all the expansion coefficients of the sought solution except for the first one. This first coefficient is determined at the second stage based on a given initial (and/or boundary) condition. The novelty of the approach is to first select a class (set) of functions that satisfy the differential equation, using a stable and computationally simple method of interpolation (collocation) of the derivative of the future solution. Then the coefficients (except for the first one) of the expansion of the future solution are determined in terms of the calculated expansion coefficients of the derivative using the integration matrix. Finally, from this set of solutions only those that correspond to the given initial conditions are selected.
Complex eigenvalues in Kuryshkin-Wodkiewicz quantum mechanics
Authors: Zorin Alexander V. , Malykh Mikhail D. , Sevastianov Leonid A.
Published: May 2022

One of the possible versions of quantum mechanics, known as Kuryshkin-Wodkiewicz quantum mechanics, is considered. In this version, the quantum distribution function is positive, but, as a retribution for this, the von Neumann quantization rule is replaced by a more complicated rule, in which an observed value AA is associated with a pseudodifferential operator O^(A){\hat{O}(A)}. This version is an example of a dissipative quantum system and, therefore, it was expected that the eigenvalues of the Hamiltonian should have imaginary parts. However, the discrete spectrum of the Hamiltonian of a hydrogen-like atom in this theory turned out to be real-valued. In this paper, we propose the following explanation for this paradox. It is traditionally assumed that in some state ψ{\psi} the quantity AA is equal to λ{\lambda} if ψ{\psi} is an eigenfunction of the operator O^(A){\hat{O}(A)}. In this case, the variance O^((A-λ)2)ψ{\hat{O}((A-\lambda)2)\psi} is zero in the standard version of quantum mechanics, but nonzero in Kuryshkins mechanics. Therefore, it is possible to consider such a range of values and states corresponding to them for which the variance O^((A-λ)2){\hat{O}((A-\lambda)2)} is zero. The spectrum of the quadratic pencil O^(A2)-2O^(A)λ+λ2E^{\hat{O}(A2)-2\hat{O}(A)\lambda + \lambda 2 \hat{E}} is studied by the methods of perturbation theory under the assumption of small variance D^(A)=O^(A2)-O^(A)2{\hat{D}(A) = \hat{O}(A2) - \hat{O}(A) 2} of the observable AA. It is shown that in the neighborhood of the real eigenvalue λ{\lambda} of the operator O^(A){\hat{O}(A)}, there are two eigenvalues of the operator pencil, which differ in the first order of perturbation theory by ±i⟨D^⟩{\pm i \sqrt{\langle \hat{D} \rangle}}.
Investigation of adiabatic waveguide modes model for smoothly irregular integrated optical waveguides
Authors: Sevastyanov Anton L.
Published: May 2022

The model of adiabatic waveguide modes (AWMs) in a smoothly irregular integrated optical waveguide is studied. The model explicitly takes into account the dependence on the rapidly varying transverse coordinate and on the slowly varying horizontal coordinates. Equations are formulated for the strengths of the AWM fields in the approximations of zero and first order of smallness. The contributions of the first order of smallness introduce depolarization and complex values characteristic of leaky modes into the expressions of the AWM electromagnetic fields. A stable method is proposed for calculating the vertical distribution of the electromagnetic field of guided modes in regular multilayer waveguides, including those with a variable number of layers. A stable method for solving a nonlinear equation in partial derivatives of the first order (dispersion equation) for the thickness profile of a smoothly irregular integrated optical waveguide in models of adiabatic waveguide modes of zero and first orders of smallness is described. Stable regularized methods for calculating the AWM field strengths depending on vertical and horizontal coordinates are described. Within the framework of the listed matrix models, the same methods and algorithms for the approximate solution of problems arising in these models are used. Verification of approximate solutions of models of adiabatic waveguide modes of the first and zero orders is proposed; we compare them with the results obtained by other authors in the study of more crude models.
Analysis of queuing systems with threshold renovation mechanism and inverse service discipline
Authors: Zaryadov Ivan S. , Viana Hilquias C. C. , Milovanova Tatiana A.
Published: May 2022

The paper presents a study of three queuing systems with a threshold renovation mechanism and an inverse service discipline. In the model of the first type, the threshold value is only responsible for activating the renovation mechanism (the mechanism for probabilistic reset of claims). In the second model, the threshold value not only turns on the renovation mechanism, but also determines the boundaries of the area in the queue from which claims that have entered the system cannot be dropped. In the model of the third type (generalizing the previous two models), two threshold values are used: one to activate the mechanism for dropping requests, the second - to set a safe zone in the queue. Based on the results obtained earlier, the main time-probabilistic characteristics of these models are presented. With the help of simulation modeling, the analysis and comparison of the behavior of the considered models were carried out.
Menakar Ulang Hermenuetika Al-Quran: Kritik Atas Pemikiran Muhammad Arkoun
Authors: Budi Setio
Published: May 2022

Qur'an interpretation will constantly evolve towards altering times. Modern thoughts advent in Islam, particularly towards Qur'an deconstruction, is an interpretations critique of the classical and middle ages. Repeated history and political interests colored the interpretation itself. So, it could not construct the text's significance according to the requirements of the times. Of this background, modern interpreters furnished another choice for reading the Qur'an scientifically with the hermeneutic approach, one of which is  Muhammad Arkoun. This writing depicted Arkoun's thoughts on the hermeneutics of the Qur'an, which has drawn a lot of disagreement among Muslims. This investigation aimed to encounter Arkoun's hermeneutics and criticism of its ideas by utilizing a library research qualitative approach. The outcomes demonstrated Arkoun's hermeneutics contains numerous shortcomings and aspects that must be abandoned, including; Arkoun's opinions that the Qur'an is not faithful, removes the theological feature of the verse, eradicates the component of the author, and that the Qur'an is a historical outgrowth. In practical terms, Arkoun's hermeneutics can only be used at the ma  haulal Qur’an level, not at the ma fi Qur’anAbstrak: Penafsiran Alquran akan selalu mengalami perkembangan seiring perubahan waktu dan zaman. Lahirnya pemikiran-pemikiran modern dalam Islam khususnya dalam kajian Alquran merupakan kritik atas penafsiran di masa klasik dan dan pertengahan. Penafsiran pada masa tersebut menurutnya hanya diwarnai dengan penggunaan riwayat yang diulang-ulang, kepentingan politik, dan sebagainya. Sehingga hal tersebut tidak mampu memproduksi makna teks sesuai kebutuhan zaman. Berangkat dari latar belakang ini para penafsir kontemporer memberikan alternatif lain dalam pembacaan Alquran yang bersifat ilmiah dengan metode hermeneutika, salah satunya Muhammad Arkoun. Tulisan ini akan memaparkan pemikiran Arkoun tentang hermeneutika Al Qur'an yang banyak menuai kontroversi di kalangan umat Islam. Penelitian ini bertujuan untuk menemukan hermeneutika Arkoun sekaligus kritik terhadap pemikirannya, dengan menggunakan pendekatan kualitatif yang bersifat library research. Hasil penelitian menunjukkan bahwa hermeneutika Arkoun mempunyai banyak kekurangan serta sisi yang harus ditinggalkan, diantaranya; Arkoun memandang bahwa Alquran tidak otentik, menghilangkan unsur teologis ayat, menghilangkan unsur pengarang dan  Alquran merupakan produk sejarah. Dalam tataran praktisnya hermeneutika Arkoun hanya bisa digunakan pada tataran ma haula al Qur'an bukan pada ma fi Qur’an.

Globalization and liberalization increasingly provide opportunities for each country to increase regional and global cooperation. Socio-economic integration is also increasing, along with community cooperation in the regional and global scope. This study aims to determine the effect of remittances and other macroeconomic variables such as FDI, inflation, and export-import on GDP per capita in ASEAN 6 countries. The panel data analysis method used is regression using panel data sourced from the World Bank and ASEAN datasets in the form of annual data. The estimation results from FEM found that exports and remittances showed a significant positive effect on GDP per capita in ASEAN 6. In addition, imports showed a significant negative effect on GDP per capita in ASEAN 6. Meanwhile, several macroeconomic variables that were not significant were FDI, which showed a significant negative effect. Positive but not significant, inflation has a negative but not significant effect on GDP per capita in ASEAN 6. The emphasis on the positive effect of remittances on GDP per capita proves that the flow of remittances into developing countries will help increase income per capita. Vice versa, a crisis that hinders the increase in the enthusiasm of emigrants. The COVID-19 pandemic delays the emigrant's production activities and increases that will hinder the flow of remittances into the country of origin, such as in ASEAN 6 countries.

Published: May 2022

The study examines the impact of monetary policy on private capital formation in Nigeria from 1980 to 2020. The study adopts Keynes's theory of capital formation as its theoretical framework. The stationarity tests show a mixed level of stationarity among the variables. Consequently, the study employs ARDL as its estimation technique. The study reveals that Monetary Policy has a positive impact on Private Capital Formation in Nigeria. Based on the findings, the study recommends that the government should maintain the current  Monetary Policy Rate (MPR) to continue impacting Private Capital Formation positively. Secondly, the government should formulates appropriate policies that will ensure that the  Exchange Rate (EXCHR) is stable so that it can improve the level of Private Capital Formation in Nigeria. Lastly, the government should embark on policies that will curb inflation or help reduce the rate of inflation to increase the level of Private Capital Formation.

Institutional trade tariffs and non-tariff barriers are major constraints to exporters and importers. It affects many developing countries' trade flows and intra-trade performance, including ECOWAS member states. From the classical economic background, the economic problems of international macroeconomics can be examined from the position of trade costs. It further states that low trade facilitation policies such as high tariffs and non-tariff barriers alone can account for a 10% loss in a national income. From these backgrounds, the study assesses the interrelation of economic integration and trade facilitation in ECOWAS and how the member states have performed in intra-manufacturing export. Using the general method of moments (GMM) with instrumental variable (IV) estimation on a dynamic model with panel data from 15 members to analyse how regional economic integration and trade facilitation relationship promote intra-regional manufacturing exports. The findings reveal that trade facilitation in ECOWAS member states is below the world average. Due to high bureaucratic processes, thus, are high costs of exporting/importing. Again, the econometric analyses reveal economic integration significantly promotes trade facilitation in member states and can influence intra-manufacturing exports in ECOWAS. At the same time, manufacturing production has a direct and significant role in manufacturing exports. Some policy recommendations that would help facilitate trade and improve manufacturing production and intra exports in the ECOWAS sub-region were made.
SDG102, a H3K36-methyltransferase-encoding gene, regulates flowering time and other processes in maize ( Zea mays L.)

Studies on histone lysine methylation in Arabidopsis thaliana and
rice ( Oryza sativa) have notably progressed in recent years.
Despite these advances in knowledge, the function of histone lysine
methylation in maize ( Zea mays L .) remains poorly
characterized. To better understand the function of histone lysine
methylation in maize, SDG102, a maize H3 lysine 36 (H3K36)
methylation gene, was chosen to study functional characterization using
overexpressed and knockout transgenic plants. SDG102-deficiency in maize
caused multiple phenotypes, including yellow leaves in seedling,
late-flowering, and increased adult plant height, while overexpression
of SDG102 led to reduced adult plant height. The key flowering
genes, ZCN8/ZCN7 and MADS4/MADA67, were downregulated in
SDG102-deficient plants. Chromatin immunoprecipitation (ChIP)
experiments showed that H3 lysine 36 trimethylation (H3K36me3) levels
were reduced at these loci. Perturbation of SDG102 expression
caused misexpression of multiple genes. Interestingly, overexpression or
knockout of SDG102 also led to genome-wide decreases or increases
in H3K36me3 levels respectively. Together, our results suggest that
SDG102 is a methyltransferase in maize that catalyzes trimethylation of
H3K36 of many genes across the genome, which are involved in multiple
biological processes including those controlling flowering time.

Published: May 2022

In this paper, considering the aggregation effect and Allee effect of
cyanobacteria population and the harvesting of both cyanobacteria and
fish by human beings, we put forward a new cyanobacteria-fish model with
two harvesting terms and a modified Holling type IV functional response
function. The main purpose of this paper is to further understand the
influence of harvesting terms on the dynamic behavior of
cyanobacteria-fish model. Critical conditions for the existence and
stability of several interior equilibria are given. The economic
equilibria and the maximum sustainable total yield problem are also
studied. The model exhibits several bifurcations, such as transcritical
bifurcation, saddle-node bifurcation, Hopf bifurcation and
Bogdanov-Takens bifurcation. From the perspective of biology, we
conclude that the harvesting terms can determine the survival mode of
cyanobacteria and fish. Finally, concrete examples of our model are
given through numerical simulation to verify and enrich the theoretical
results.
