Levels of Difficulty in Division
Authors: Ruddell Arden K.
Published: October 2020

Division of whole numbers is a relatively complicated computational process. It is complicated because it involves each of the other processes: addition, multiplication, and subtraction, and also includes principles unique to division alone. Thorough understanding of division is dependent upon knowledge and understanding of the interrelationships between the four processes—addition, subtraction, multiplication, and division. Following are the understandings commonly made explicit.
Some Observations on the Contemporary Mathematical Scene
Authors: Newsom Carroll V.
Published: October 2020

Teachers of mathematics find that they are in a dilemma at the present time that is both interesting and troublesome. From one horn of the dilemma flies the ba nner signifying great popularity, for mathematics teachers have suddenly become indispensable; someway they have become tied up with national survival. From the other horn flies the banner signifying gross unpopularity, for mathematics teachers, according to many emphatic reports, are poor teachers, and they have been teaching the wrong things.
Discovering the Multiplication Facts
Authors: Grossnickle Foster E.
Published: October 2020

A pupil maylearn the basic facts in multiplication by rote or he may discover them for himself. Usually a pupil finds it advantageous to have objective aids of some kind to help him find the answers to different number groupings in this process. A number grouping consists of any combination of two one-place numbers.
A Trip to Notation Land
Authors: Green Mary Geraldine
Published: October 2020

Does your arithmetic class need a new zip and zing? Well, fifty-eight fourth graders and fifty-two second graders found this zip and zing that can make arithmetic become more meaningful and alive through the study of this science of several centuries ago—when the people of Egypt and Greece realized that they needed a system of counting over and above the primitive man's method of one-to-one correspondence. Thus we find that these one hundred ten children in Detroit, Michigan have arrived recently at modern concepts of arithmetic through their brief travels back to the days of ancient Egypt and Greece. These pupils were conducted on their tour by Sister M. Alphonse and Sister M. Charitas who were pursuing a course of College Arithmetic. In this course, principles of arithmetic are taught for the purpose of giving future elementary teachers a firm background in arithmetic, and we also concern ourselves with the actual teaching of arithmetic. As a result of this, Sister Charitas is catching the express to tell how she helped her second graders understand zero being used as a place holder. She accomplished this through the comparison of the Hindu-Arabic system of notation with Egyptian methods of notation.
Prime Numbers and Factoring
Authors: Goodman Frederick L.
Published: October 2020

To teach discrimination between prime and composite numbers and to introduce the concept offactoring, a set of baby's blocks makes an excellent teaching aid. Although I have carried out my experiments with eighth graders, I feel the blocks would be useful even in the high school.
The Dual Progress Plan in the Elementary School
Authors: Heathers Glen , Pincus Morris
Published: October 2020

At the recent meeting of the National Council of Teachers of Mathematics held in New York City,* one elementary school panel dealt with the problem of providing better instruction in mathematics to gifted students. Thus far, most attempts to meet the needs of gifted students have depended upon horizontal enrichment. A difficulty has been that most elementary teachers lack sufficient knowledge of mathematics to make enrichment programs successful. The mathematics preparation of elementary school teachers must be improved.
Take a Number and Build a Number System
Authors: Willerding Margaret F.
Published: October 2020

The decimal system of notation is one of man's greatest inventions. The greatness of the invention is not in the selection of ten as the base, but rather in the system that is functional and simple-a system that works with any base that one may wish to use. There are, without doubt, a number of bases that would have been superior to ten.1 Actually, the origin of ten as a base of our decimal system is not known. Some people state that ten was selected because man has ten fingers, but obviously such a statement oversimplifies the genius that operated in the selection of zero as the initial symbol for the decimal system of numerals.
Algebra in the Fourth Grade
Authors: Parsons Cynthia
Published: October 2020

Some fourth graders are really learning algebra. As a matter of fact, so are third, fifth, sixth, and seventh graders. A basic course in algebra has been prepared under the direction of Dr. Robert Davis of Syracuse University. This course consists of a modified form of 9th and 11th grade algebra arranged for presentation to elementary school children. It got its name—The Madison Project—from the Madison School in Syracuse where it was first introduced in 1957.
The Equation Method of Teaching Percentage
Authors: Kessler Rolla V.
Published: October 2020

The equation is the basis of aJl problems concerning arithmetic, mathematics, chemistry, physics, and engineering. A problem is an incomplete equation. When you get the answer, the equation is complete. Perhaps we should rewrite our elementary arithmetic books and teach children from the beginning to solve equations. In our present method, we let our children run into equations like “hitting a stone wall” in Algebra. Why not set up a system of problem solving in the elementary school which is basic to all problems? Ratios will be easier in Chemistry and Physics when children are taught to solve equations from the very beginning.
The Division of Common Fractions
Authors: Kolesnik Theodore S.
Published: October 2020

There has been a Good Deal of discussion recently in regard to the best method of teaching the division of common fractions. Some teachers believe that the common denominator method is the one that should be taught. Others feel that the inversion method is best if it is preceded or followed by an explanation of why the inversion is mathematically sound. Another group feels that the inversion method should simply be “algorized” with any rationalization being delayed until such time that the pupil is mature enough to understand the complex fraction that is involved in the rationalization. Still another group favors the teaching of all methods with the pupil selecting the one that he particularly favors.
Divisibility by Odd Numbers
Authors: Kilgour Alma Jean
Published: October 2020

TESTS FOR DIVISIBILITY by seven and thirteen were described by Francis J. Mueller in the November 1958 issue of THE ARITHMETIC TEACHER. In addition, proofs for these tests were presented in the above-mentioned article. However, the method of deriving such rules was omitted. When this method is known, the tests may be extended to include divisibility by any number ending in 1, 3, 7, or 9. Since divisibility by numbers ending in 5 may be ascertained on sight, a means is thus provided for determining exact divisibility by any odd number.
Bibliography of Books for Enrichment in Arithmetic

THE FEBRUARY, 1956 ISSUE of THE ARITHMETIC TEACHER offered a helpful blibliography entitled, “The Elementary School Mathematics Library,” by Ruth Hutcheson, Edna Mentor, and Marjorie B. Holmberg. In the February, 1959 issue of his same journal, Aldren H. Hess presented another bibliography entitled, “ Bibliography of Books for Enrichment in Arithmetic.” The following bibliography, recently revised, brings the listing up-to-date.
Dramatics in Arithmetic
Authors: Cameron Robert T.
Published: October 2020

While Leafing Through several Catalogs and pamphlets, I found nothing in dramatics for the teaching of arithmetic and little or nothing for any of the other basic skill subjects for that matter. Most plays were for the social studies, or for holidays or entertainment. It appeared that the idea of writing a play as a learning activity had escaped the imaginations of most writers. As I neared the end of my resources, however, I picked up Paine's Teacher's Catalog and this title caught my eye; “Fractions are Such Queer Things,” written by Grace I. Scott, copyright 1934.

Book Review
Authors: Sueltz Ben A.
Published: October 2020

Although this study is based upon the grade levels seven through twelve and the data represents the three states of Maryland, New Jersey, and Virginia, there is a good deal of information that will be of interest to teachers at all levels. Inasmuch as there is a good deal of ferment in the area of mathematics, it is interesting to note that onefifth of the teachers received their training before 1950 and that 39% of the teachers had not taken as much mathematics as a course in calculus. On the average the mathematics teachers have 23 semester hours in mathematics and 31 semester hours in education. What conclusion might one draw: “Training in mathematics is less important than training in education,” or “It is easier to learn mathematics after graduation and on the job than it is to learn the principles of educational theory and practice,” or “Might it be a little easier to obtain credits in education than in mathematics?”
The Point of View of the Twenty-fifth Yearbook
Authors: Grossnickle Foster E.
Published: October 2020

Instruction in arithmetic, the Twentyfifth Yearbook of the National Council of Teachers of Mathematics, is the third yearbook published by the Council which deals with arithmetic. The present publication presents the point of view that was introduced in previous yearbooks in this area. To a large extent, therefore, this book represents a progress report dealing with the acceptance of ideas that were initiated in earlier yearbooks. For this reason it seems advisable to review the philosophy of learning as applied to arithmetic in former yearbooks in this field.
Admirable Numbers and Compatible Pairs
Authors: Sachs J. M.
Published: October 2020

The object of this paper is to suggest an extension of the number theory concepts of perfect numbers and amicable pairs of numbers. The suggested extension can provide interesting material for practice with the basic operations with integers. In addition to serving as a medium for this necessary practice, this extension yields an area in which children can explore and make discoveries. In their explorations they will see mathematics as a subject of ideas in which intuition, imagination, and speculation play large roles. This is an aspect of this discipline which is not exhibited early enough or often enough, probably because we, as teachers, find ourselves so greatly concerned with teaching the necessary techniques.
Depth Learning in Arithmetic—What Is It?
Authors: Junge Charlotte W.
Published: October 2020

The acquisition of skills has been consistently recognized as one of the basic aims of education to which the elementary school should contribute. From colonial times to the presen t, much of the attention of schools and of teachers has been centered on this aspect of educa tion. Furthermore, this preoccupation with the development of skills has been associated largely with the “three R's.” Reading, writing, and arithmetic, frequently referred to as tool subjects, have been presumed to encompass all the skills which are of real importance in the education of children.
A New Look at the Basic Principles of Multiplication with Whole Numbers
Authors: Hannon Herbert
Published: October 2020

Much has been written concerning the desirability of stressing the basic principles underlying the fundamental processes. These are usually identified by calling them the Commutative, Associative, and Distributive Laws. Certainly a better understanding of the fundamental processes will result if these principles are understood and stressed by both the teacher and the elementary student. It is the purpose of this article to discuss these principles from the standpoint of their development from a process of logical reasoning, or perhaps we should say from their “reasonableness.”
Problems without numbers
Authors: Klas Walter L.
Published: October 2020

The present concern to secure challenging programs for more able students has resulted in a number of interesting proposals. It appears that the acceleration versus enrichment problem is not yet settled. I ndeed, the proposals for challenging the more able students appear about evenly divided between the alternatives. The important fact is that people are thinking about the problem and many good solutions are being offered and tested throughout the country.
Testing—without tests
Authors: Harrison K. L.
Published: October 2020

We often observe that students do poorly on tests in mathematics because of the psychological element of fear. This element may be reduced to a minimum with the same amount (possibly more, in some instances) of learning, and the teacher still achieves the primary purpose (often forgotten by teachers themselves) of a test.

Evidence available from general aptitude, special aptitude, and achievement tests and observations by highly skilled teachers of arithmetic leads us to conclude t hat not all pupils have the ability to master arithmetic skills according to a set schedule. And yet, quite frequently all pupils in any given class are taught simultaneously the same arithmetic principles and processes.

Don't count your chickens before they hatch
Authors: Lambert J. William
Published: October 2020

In the first grade we feel that the arithmetic period should be a learning laboratory. The children should be involved in various concrete and meaningful experiences in which numbers play a vital role. These experiences may include grouping and manipulating objects, measuring and constructing objects, or dramatizing number experiences, all of which help the children acquire an understanding of number concepts.

Are the children who come to kindergarten ready for mathematics experiences? We are told by authorities that school should be a continuous learning situation. If this statement is valid, we should continue mathematics experiences in kindergarten because the children have already had number experiences outside of school.
Arithmetic in Pakistani elementary schools
Authors: Ali Shaikh Asghar , Kennedy Leonard M.
Published: October 2020

The curriculum of elementary schools revolves around the pivot of the three R's. Arithmetic is considered to be the most important subject, and right from the first grade it absorbs the most of the teachers' and pupils' attention in Pakistan. But, at the same time, this is the subject which is perhaps least liked by children. For them it is a hard nut to crack. They are punished because they are poor at figures. A large number of children give up their education during the first five years of elementary education. A relatively small percentage of the boys and girls who complete their elementary-school education go on to complete high school.1 Along with other factors, a child's failure to grasp the knowledge imparted is the most important reason. In the last several decades in Pakistan, mathematics and English have been considered responsible for the poor pass percentage, which usually lies in the range of 50 to 60 per cent. Thousands of disgusted high-school students bid farewell to education forever for the lower attainment in arithmetic and foreign language. What a horrible waste!
In the classroom: Problem solving with number-picture problem situations

The class was inspired by the weather to develop its first picture problem situation. The teacher sketched at the chalk-board in response to children's suggestions and guided them so that basic grade-level number concepts were included. For example, the first cooperative class sketch featured a snowy hill and boys and girls with sleds. All data are not pictured; some are provided as factual information. The sketch (Fig. 1) and some of the resulting number problems were similiar to the following.
The Miquon mathematics program
Authors: Rasmussen Don , Rasmussen Lore
Published: October 2020

The current mathematics program at the Miquon School began four years ago (one year before Sputnik). Several of the more capable pupils, already working at a higher level in arithmetic, were sent to the “remedial teacher” to see what might be done to further raise their skills in quantitative thinking. Teachers and pupils were very free to work on any level of discovery—as long as they would have fun! Freed of any curriculum restrictions, as well as the psychological principles that provide a level of a curriculum, the group attacked problems for which their arithmetic had not prepared them. This did not stop them, however, because they discovered solutions in logic, solid geometry, algebra, graphing, set theory, etc. In short, they discovered mathematics and used the few, simple operations of arithmetic only as they were needed.

New content in mathematics—first through fourth grades
Authors: Heard Ida Mae
Published: October 2020

For those venturesome souls who dare to teach new content the rewards are many. We have recently experienced such satisfaction. Five of our teachers tried Geometry for Primary Grades, Book One by Hawley and Suppes* during the spring semester of 1962. This new content was taught in two fourth-grade classes and in one class each of Grades l-3. There was one class of gifted fourth graders, while the pupils in the other classes were unselected. All of the children enjoyed their study of geometry, but the fourth-grade children seemed to profit most from their study of lines, angles, and constructions. A few of the children experienced their only academic success in geometry. All children had a more adequate concept of themselves as learners because of their study of geometry.
How well do pupils estimate answers?
Authors: Faulk Charles J.
Published: October 2020

The current emphasis on mathematics in the elementary schools makes it more imperative that all elementary mathematics teachers emphasize quality in their teaching. Sueltz has said, “It is the teacher who sets the stage or creates an atmosphere or climate for learning; it is he who selects and adjusts methods of learning for a class, for group, and individuals; it is the teacher who selects the subject matter and the way in which it is learned.”1 A challenge is clearly indicated. How can the teacher meet this challenge? Beginning should be rather easy because the teacher works with the children who need help in this area. Knowing the needs and interests of boys and girls should enable teachers to make some of the decisions which Sueltz mentions. Keeping abreast of current developments in the field of elementary mathematics is a second way of meeting this challenge. Teachers who are not presently reading and studying will find that their background of training will not enable them to understand the professional literature within a year or so. A third way in which teachers can strengthen the instructional program in mathematics is through in-service education. In this manner the results of many experimental procedures which have proven successful may be discussed and incorporated into classroom procedures. Techniques and methods presently used may be reexamined to determine whether or not clarification, modification, deletion, or complete acceptance is most appropriate at this time.

Répeter: Uma análise composicional
Authors:   Universidade Federal de Santa Maria (UFSM), Filho Paulo Rios
Published: October 2020

Este trabalho introduz a ideia de análise composicional, como uma alternativa, para a área de pesquisa em composição musical, a enfoques analíticos tradicionais de cunho essencialmente musicológico. Para tanto, apresento a análise de uma peça para violão de minha autoria, intitulada Répéter, que, a partir da coleta de uma série de dados, impressões, materiais e registros diversos do processo composicional, ilustra um caminho possível para a prática analítica, na área. Antes de apresentá-la, no entanto, comento brevemente as bases dessa abordagem, através de: 1) uma discussão introdutória acerca dos contextos acadêmicos e artísticos que justificam a proposta; e 2) uma abordagem conceitual da análise composicional a partir das ideias de linhas, lugar, emaranhado e composicionalidade de Deleuze e Guattari (1995), Tim Ingold (2008, 2011, 2012) e Paulo Costa Lima (2012), respectivamente. Com isso, espero lançar um horizonte analítico experimental, que é mais uma extensão do próprio processo criativo, do que uma busca por representação ou explicação da obra, enquanto produto daquele processo.
Poética do contágio: estudos analíticos como mote para uma conversa entre compositores
Authors:   Universidade Estadual de Londrina/Professor Adjunto, Ficagna Alexandre
Published: October 2020

Estudos analíticos (formais ou despretensiosos) tomados como mote para iniciar uma conversa entre compositores, de modo a amplificar uma poética do contágio. Lido a partir de Deleuze e Guattari (1997) e Ferraz (2007), o conceito fornece uma imagem para se pensar os pequenos diálogos que permeiam o processo de criação, com foco na conversa entre compositores: conversa que pode ser diretamente verbal, mas principalmente através de suas obras, quando comumente participa a análise. Na composição de duas peças, o autor se valeu da análise para estabelecer conversas e diálogos. Em Inquietações, o contágio ocorreu por meio de estratégias técnicas e musicais, em diálogo principalmente com duas Sequenzas de Berio. Em Tons de amarelo patético, a composição ocorreu paralelamente à análise de Antiphonas, de Lima, análise que permitiu observar o contágio como modus operandi da peça em si. Pode-se pensar numa poética do contágio que se alastra epidemicamente, através de análises e conversas.
Berimbau: instâncias de decisão compartilhada em uma composição colaborativa
Authors:   Universidade Federal da Bahia, Espinheira Alexandre Mascarenhas , Cardassi Luciane Aparecida ,   UNIVERSIDADE FEDERAL DA BAHIA
Published: October 2020

O presente artigo apresenta uma reflexão sobre a composição colaborativa da obra Berimbau para piano, voz e sons eletroacústicos. Os objetivos intentados foram: a) oferecer um panorama do estado da arte da pesquisa em colaboração artística (JOHN-STEINER, 2000; BARRET, 2014) e da criatividade distribuída (CLARKE; DOFFMAN, 2017); b) descrever brevemente as teorias da composição desenvolvidas por Laske (1991) e Reynolds (2002), iluminadas por Rios Filho (2010); e, a partir delas, c) propor uma reflexão sobre instâncias de decisão compartilhada entre colaboradores com o objetivo de compor uma obra musical. Para tanto, utilizamos episódios do processo colaborativo da obra Berimbau para exemplificar as diversas fases e instâncias de decisão propostas no esquema. Acreditamos que o presente artigo possa ser somado às iniciativas de reflexão acerca da colaboração artística e oferecer alternativas para a compreensão e estudo de como os processos colaborativos podem ser desenvolvidos.
Experimentação como interseção entre composição e performance na criação musical: uma experiência de colaboração
Authors:   Universidade Federal do Tocantins, Oliveira Heitor Martins , Silva Dario Rodrigues , Hernández Gina Arantxa Arbeláez ,   Universidade Federal do Rio Grande do Sul, Simões Renan Colombo , Gomes Sabrina Souza
Published: October 2020

O artigo aborda o papel da experimentação na colaboração criativa ‒ composição e performance ‒ do Coletivo N·S·L·O. A investigação é construída a partir dos registros colecionados ao longo do processo criativo e de relatos produzidos pelos(as) próprios(as) integrantes. Assim, a discussão considera as perspectivas particulares de cada um(a), até a consolidação dos produtos musicais. Nesse processo, a experimentação cria um espaço em que compositor e intérpretes atuam juntos de maneira decisiva para o resultado criativo alcançado. Os resultados das experimentações são incorporados à composição, por meio da escrita indeterminada, e à construção da performance, por meio de jogos constituídos por materiais musicais, ações e interações. A colaboração, embora preserve a divisão de papéis, assume caráter horizontal e flexível. A proposta estética abarca os aspectos de teatralidade e jogo como resultado da dinâmica entre escrita indeterminada e performance.
Rumo aos "mundos secundários" na ópera Elegy for Young Lovers de Henze
Authors:   Universidade Estadual de Campinas, Alireti Cinthia Pinheiro
Published: October 2020

Este artigo tem por objetivo traçar as origens dramático-musicais da ópera em três atos Elegy for Young Lovers (1961), com música do compositor alemão Hans Werner Henze e libretto de Auden e Kallman. Através da pesquisa de fontes literárias e teóricas sobre esta obra, com ênfase nos escritos dos próprios autores, foi examinada a existência de recursos extrínsecos que contribuíram para a constituição da estrutura dramática interna. Estes recursos se tratam, por um lado, de influências culturais que interagiram na construção da identidade artística da obra e, por outro lado, de convenções emprestadas de outras tradições, tais como os tópos do repertório lírico, os conceitos de mundos primários e secundários da literatura de ficção, e possíveis referências a personalidades conhecidas, as quais serviram de inspiração para a caracterização de personagens. Verificou-se que recursos extrínsecos, além de contribuírem para os processos de dramatização na ópera, também desempenham um papel importante na elaboração de um discurso didático subjacente.
Pensamento Composicional Dialógico de Cada Ano Sem Debussy: dez versos sobre o seu nome
Authors:   Universidade Federal de Minas Gerais, Vasconcelos Felipe Mendes
Published: October 2020

Este artigo investiga as relações dialógicas presentes no processo composicional da peça orquestral Cada ano sem Debussy: dez versos sobre o seu nome (2019). Busca, à luz do dialogismo bakhtiniano, refletir sobre composição e os conceitos de enunciado e dialogismo musical. Apoiado em três conceitos de dialogismo (FIORIN, 2016) – constitutivo, mostrado e entre sujeitos –, examina como a peça musical pode ser enfocada sob essas perspectivas. Para isso, a análise ressalta a interatuação entre o material próprio e o de outrem empregados na composição. Conclui que, frente a um pensamento composicional dialógico, as propostas de Bakhtin podem ser ferramentas eficazes de investigação.
Composição de interface com etnomusicologia: uma perspectiva materializada em 5 obras contemporâneas
Authors:   Universidade Estadual de Feira de Santana, Amaro Vinicius Borges
Published: October 2020

Este trabalho apresenta discussões acerca do processo composicional de cinco obras compostas a partir de uma perspectiva de interface entre composição e etnomusicologia, centrada numa pesquisa cujo objetivo se estabelece como um estudo da música de candomblé ligado às noções compositivas impressas em seus processos rítmicos. Buscando um suporte em teorias do ritmo (COOPER; MEYER, 1960; KRAMER, 1988; HESTY, 1997), na literatura sobre música de candomblé e música africana (LÜHNING, 1990; KUBIK, 2010; BRANDA LACERDA, 2014; AGAWU, 2016), e por meio de um estudo etnográfico, cinco processos rítmicos foram identificados, conceitualizados e exemplificados: 1) ressignificação rítmica; 2) dissociação rítmica, 3) sintonização rítmica; 4) suspensão rítmica e 5) sublimação rítmica. Estes são problematizados na produção artística em questão, através de um impulso adaptativo relativo ao abrangente imaginário da música de concerto contemporânea, em suas dimensões temporais, texturais, gestuais e formais
O Ritmo e a interseção de culturas na obra Areia II, de Alexandre Lunsqui: influências em seu processo composicional
Authors:   Universidade Estadual Paulista - UNESP, Lunsqui Alexandre , Davino Guilherme do Nascimento
Published: October 2020

Este artigo pretende analisar aspectos rítmicos na obra Areia II, do compositor Alexandre Lunsqui. Analisamos as diversas influências rítmicas que ocorrem na obra, sejam elas vindas do repertório erudito, sejam oriundas de manifestações musicais externas a este repertório, como a música tradicional africana. O artigo mapeia as figuras rítmicas usadas na obra, contextualizando- as dentro das estratégias criativas empregadas pelo compositor.
Projetando o espectro do som no espaço: imagens-movimento de parciais e grãos sonoros
Authors:   Universidade Federal do Mato Grosso, Rossetti Danilo
Published: October 2020

Enquanto o tempo é sempre mencionado como característica inerente à música, o espaço na maioria das vezes não é tratado como categoria operatória da composição, algo que mudou de figura durante o século XX devido a novas abordagens composicionais e teóricas. Este artigo apresenta a construção de um instrumento digital em Max/MSP maleável a diferentes configurações de difusão sonora e congregando diferentes possibilidades de síntese com espacialização em ambissonia de ordem superior, com o intuito de integrar o espectro do som à espacialização na música eletroacústica (acusmática ou mista) pela projeção de parciais e/ou grãos em movimento no espaço de difusão. Para tanto, são apresentados os seguintes referenciais teóricos: 1) abordagens históricas do espaço na composição musical com ênfase nos séculos XX e XXI; 2) o sistema Ambisonics; e 3) uma conceituação sobre os modelos sonoros ondulatório e granular, dessa forma situando a proposta na área da criação musical para sistemas com grande densidade de alto- -falantes. Como resultados, apresento as ferramentas de composição e espacialização incluídas no instrumento digital desenvolvido, além do experimento composicional Imagens transdutivas. Como conclusão, esboça-se uma reflexão sobre a percepção sonora em sistemas imersivos a partir das ideias de imagem-movimento e blocos de espaço-tempo.

Published: October 2020

Objective: Determining geographical distribution and local dietary patterns involved in being obese is useful for designing intervention strategies. Methods: We selected residents between 18 and 65 years old from 11 Chinese provinces to compare dietary patterns and BMI
from the China Health and Nutrition Survey packages in 2011. We used linear and logistic regression analyses to assess the strength of association among geographic variables, the obesity problem, and dietary patterns. Results: The overall prevalence of overweight and obesity in the
North was 10.51% higher than that in the South. Northern dietary patterns feature a high intake of wheat and soybeans, whereas southern dietary patterns feature a high intake of rice, vegetables, meat, and poultry. The estimated coefficient of regional variables on dietary score is 1.49, the
estimated coefficient of regional variables on the odds ratio for being overweight is 1.68 and for being obese is 2.04. Multivariate logistic regression including both variables of South-North areas and northern dietary patterns showed a significant correlation with being overweight or obese.
Conclusions: Northern areas and their local dietary patterns are more likely to contribute to overweight and obesity. Our study provides empirical evidence for policies that target the ''obesogenic'' environment and promote opportunities for persons to access healthy dietary patterns
and nutritional balance.

A single mutation in Crimean-Congo hemorrhagic fever virus discovered in ticks impairs infectivity in human cells

Published: October 2020

Crimean-Congo hemorrhagic fever (CCHF) is the most widely distributed tick-borne viral infection in the world. Strikingly, reported mortality rates for CCHF are extremely variable, ranging from 5% to 80% (Whitehouse, 2004). CCHF virus (CCHFV, Nairoviridae) exhibits extensive genomic sequence diversity across strains (Deyde et al., 2006; Sherifi et al., 2014). It is currently unknown if genomic diversity is a factor contributing to variation in its pathogenicity. We obtained complete genome sequences of CCHFV directly from the tick reservoir. These new strains belong to a solitary lineage named Europe 2 that is circumstantially reputed to be less pathogenic than the epidemic strains from Europe 1 lineage. We identified a single tick-specific amino acid variant in the viral glycoprotein region that dramatically reduces its fusion activity in human cells, providing evidence that a glycoprotein precursor variant, present in ticks, has severely impaired function in human cells.
Improvement of the Transient Stability of a 14-bus Network Using a Superconducting Fault-Current Limiter SFCL
Authors: Belkhiri S. , Bouroubi M. , Harrabi A.
Published: October 2020

This study presents a new strategy for implementing the superconducting fault current limiter SFCL in order not only to limit short - circuit currents but also to improve the stability of electrical networks in the presence of faults. The calculation of the impedance that the limiter must introduce into the test network at the moment of the failure is obtained from a three-dimensional computation code, developed and implemented under MATLAB environment where the formulation in magnetic vector potentials A and scalar potential Electric V is adopted to solve the electromagnetic problem and the heat diffusion formulation is adopted also to solve the thermal problem. The coupling is ensured by an alternating algorithm and the numerical resolution of the problem is ensured by the method of the finite volumes in its three-dimensional version in order to avoid certain problems of numerical convergence linked to the strongly nonlinear character of the problem to be solved. The modeling of the network tests will be made by PSAT under the environment MATLAB.
Collisional and resonance absorption of electromagnetic waves in a weakly collisional, inhomogeneous magnetoplasma slab
Authors: Rawwagah F. , Al-Ali M. , Al-Khateeb A. , Bawa'aneh M.
Published: October 2020

Absorbance of normally incident electromagnetic wave on a cold, weakly collisional, and inhomogeneous magnetoplasma slab is investigated. The plasma density is Budden-like sinusoidal profile, where the inhomogeniety is treated as a multilayered system of homogeneous sub-cells within the transfer matrix technique. For incident wave frequencies much above the ion cyclotron frequency, only right hand circularly polarized waves are relevant for wave propagation parallel to a static magnetic field. Calculations are performed in normalized parameters, that make the results suitable for many applications including atmospheric and laboratory plasmas. The presence of the dc-magnetic field leads to the formation of two absorption bands explained by plasma collisional dissipation and electron cyclotron resonance in the low frequency branch of the $R$-wave below the electron cyclotron frequency. The transmittance shows the emergence of the low frequency electron cyclotron wave, which becomes a Whistler mode at very low frequency. More detailed discussion on the effect of plasma collisionality, inhomogeneity, and dc-magnetic field on the propagation characteristics is given at the relevant place within the body of the manuscript.
Selection of Alternaria Fungi Control Treatments in a Citrus Grove through the Lens of the Electre Technique: A Case Study in San Luis Potosi, Mexico
Authors: Landeta Juan Manuel Izar- , Molinar Raul Hernandez-
Published: October 2020

Aims: To evaluate the cost-effectiveness of five control treatments (pesticides) for an Alternaria fungi variety in a citrus grove in Mexico.

Study Design: Field applications of pesticides were used to combat an infestation of the Alternaria fungus.

Place and Duration of the Study: The study took place in an orange citrus grove in Ciudad Fernandez, San Luis Potosí, Mexico, from October 2018 to August 2019.

Methodology: Field trials with five control treatments were applied to randomly selected rows of infected orange trees. The assessment of treatments was carried out using the multi-criteria decision method (MCDM) known as ELECTRE with six evaluation criteria: cost, effectiveness, toxicity (e.g., environmental impact), difficulty of preparation, ease of application, and expiration date.

Results: The results reveal that the best option to control the fungus of the Alternaria is the use of a biological product based on microorganisms, instead of standard options such as agrochemicals, or synthetic preparations known as “broths.” A sensitivity analysis reveals that the result may be affected by changing the weight of the criteria.

Conclusion: The best treatment is the biological product because it is the most effective treatment to control the fungi plague, it is not toxic or expensive, and it does not have a measurable impact on the environment. However, the results are sensitive to changes in the weight of the criteria.
