An Empirical Analysis of Defense-Economic Growth Relationship in Pakistan
Authors: Sohail Muhammad Tayyab , Jamal Qaiser
Published: April 2020

Since the last quarter of 20th century the macroeconomic impact of defense spending on the economic growth have attracted the attention of many researchers, academician and policy makers. During the cold war the US defense strategy against the Soviet Union was the first time when it was derived. After the cold war a reduction in defense spending was observed which was named as “Peace Dividend”. Most of the developing and developed countries try to make peace and promote it but still it is seen that large portion of the overall global GDP is spent on the defense sector. This study surveys defense-growth nexus by incorporating openness to trade, external debt, gross capital formation and labor force in production function. The study uses annual time series data over the period 1972-2016. For estimation purposes, the study employed ADF unit root test and P-P unit root test for testing stationarity properties, ARDL Bound test to cointegration used for testing long run relationship. The empirical evidence of the study reveals that Economic growth is positively affected by spending on defense sector, capital investments, labor force, and openness to trade in long run while external debt has a negative effect on economic growth. Apart from this, empirical evidence also suggests that in short run; there is positive imperative role of capital investment, defense spending, and openness to trade in growth process, while external debt retards the pace of economic growth. Results of the study indicates that defense spending could be used as a fiscal tool for achieving sustainable growth, government should invest high R&D in defense sector in order to produce modernize defense products which would reduce high importation cost of expensive defense products, and through selling these defense products, not only the defense sector would be self-sufficient but would also contribute to growth process by exporting the defense products.

Published: April 2020

The aim of the research was to study steppe cherry cultivars of various environmental origin in the context of their productivity, environmental plasticity and stability in the environments of Chelyabinsk Province. Evaluation of the studied set of cultivars helped to identify adaptable steppe cherries: ‘Izobilnaya’ (4.39 t/ha; KA = 1.54), ‘Shchedraya’ (4.42 t/ha; KA = 1.37), ‘Galimovka’ (3.83 t/ha; KA = 1,36), ‘Mayak’ (4.04 t/ha; KA = 1.30), ‘Ashinskaya’’ (t/ha 3.42; KA = 1.28) and ‘Mechta Zauralya’ (3.29 t/ha; KA = 1.07). The most interesting among them are intensive-type cultivars responding well to improved growing conditions, such as the steppe cherry cultivars developed at Sverdlovsk Horticultural Breeding Station: ‘Shchedraya’ (bi = 1.99), ‘Mechta Zauralya’ (1.85) and ‘Mayak’ (1.47). The Chelyabinsk cultivar ‘Galimovka’, submitted for state trials in 2018, falls under the category of environmentally plastic and stable cultivars (bi = 0.77; Si2 = 0.5), while cv. ‘Ashinskaya’ demonstrated during the tests a neutral genotype, as it poorly responded to changing environmental conditions (bi = 0.32; Si2 = 0.1). A new cultivar, ‘Vita’, with a fairly high yield (3.05 t/ha), developed at Sverdlovsk Horticultural Breeding Station, belongs to the environmentally plastic category (bi = 1.10), but its yield stability proved to be insufficient in the environments of the Southern Urals (Si2 = 2.2).

Published: April 2020

Peanut is one of the most important crops in the Fabaceae Lindl. (Leguminosae L.) family. South America is considered to be the homeland of peanut, but now this crop is cultivated in America, Africa, Australia, Europe and Asia. The modern phylogenetic system of the genus Arachis L. includes 79 wild species and one cultivated species of common peanut (A. hypogaea L.). Diploid species contain 2n = 20 chromosomes of the A, B or D genome, tetraploids have A and B genomes. The А and В genomes are sequenced. Special biological features of all peanut varieties are the presence of chasmogamous and cleistogamous flowers and the development of pods only underground (geocarpy). Along with high requirements for improving the quality of oil and food products, much attention is paid to their safety: resistance to aflatoxin contamination and mitigation of allergenicity. Peanut cultivars vary in plant habit, shape and color of pods and seeds. Their growing season in Africa, Latin America and Asia is from 160 to 200 days, so early-ripening forms need to be selected for the south of the Russian Federation. Breeders from the Pustovoit Institute of Oil Crops (VNIIMK) have developed peanut cultivars with a yield of 2.0–3.3 t/ha and growing season duration of 115–120 days, adaptable to the environments of Krasnodar Territory. At present, there is no large-scale peanut production in Russia, nor any breeding efforts are underway. As for the world, along with conventional breeding practices (individual selection, intra- and interspecies crosses, etc.), peanut is widely involved in genomic studies. A number of cultivars highly resistant to pests, diseases and drought have been released. Over 15,000 peanut accessions are preserved in the world’s gene banks, including 1823 accessions in the collection of the Vavilov Institute (VIR). Utilization of the worldwide genetic resources of peanut and use of modern research technologies will contribute to the revival of peanut cultivation in Russia.

Authors: Loskutova N. P. , Ozerskaya T. M.
Published: April 2020

The article covers the issues of plant genetic resources mobilization to the VIR collection from the territories of Pakistan, Bangladesh (until 1947, British India), and Bhutan as a result of collection missions, seed requests, and germplasm exchange. Repeated expeditionary surveys of the territories of modern Pakistan and Bangladesh resumed in the postwar period. In total, from 1971 to 1979 three expeditions were launched: in 1971 and 1978 to Pakistan, and in 1979 to Bangladesh. The first and the only expedition was sent to Bhutan in 1989. As a result, 2911 plant samples were collected and delivered to the Vavilov Institute. Among the collected plant materials, the most numerous were samples of groat crops (885), industrial crops (554), vegetables (517), and cereals (463). In addition to direct collecting, the Institute was constantly ordering plant germplasm through mail requests. There was no inflow of germplasm from Bhutan either in the prewar period or from 1946 to 2019. From Pakistan 338 samples were received, mostly through the USSR Ministry of Agriculture. Only 28 accessions were added to the Institute’s collection from Bangladesh. In total, over the entire period of the Institute’s existence, the total amount of germplasm mobilized from Bangladesh, Pakistan and Bhutan amounted to 3277 accessions, representing 130 plant species. Among them there were many landraces, wild species and crops wild relatives.

Published: April 2020

The establishment and progress of potato cultivation in the Kola Peninsula are closely associated with the Polar Experiment Station of the N.I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR). The data are presented on the development of early-ripening and high-yielding potato cultivars based on the source material from the VIR collection: ‘Imandra’, ‘Sestra Imandry’, ‘Murmansky’, ‘Snezhinka No. 3’, ‘Khibinsky ranny’, etc. Prominent breeders and scientists, who worked at different times at the Polar Station, contributed to the release of unique early-ripening potato cultivars: J. H. Eichfeld, M. N. Veselovskaya, I. A. Veselovsky, F. I. Manykov, M. A. Vavilova, N. N. Ivanova, L. A. Dremlyug, A. M. Kozeletskaya, S. A. Anikina, G. D. Melnichuk, etc. Some of the cultivars developed from 1937 to 1968 are still used in large-scale potato production in Murmansk Province. Every year the cultivar and species diversity of potatoes is planted in the fields of the Arctic North. Today, the extensive material from the potato collection makes it possible to study the impact of environmental factors, identify sources of earliness and productivity, and conduct breeding activities aimed at the release of early cultivars.
Fodder qualities of heterotic hybrids from intergeneric crosses between maize and eastern gamagrass
Authors: Panikhin P. A. , Sokolov V. A.
Published: April 2020

Green biomass yield and fodder qualities are the starting point in the choice of forage crops. Maize, as a plant with the C4 pathway of photosynthesis, is highly efficient in transforming the energy of light into chemical bond energies, which ultimately leads to the highest yield per unit area of cultivated land. Its grain and green biomass possess good fodder qualities and are actively used in feed rations for cattle, smaller ruminants, and poultry. Eastern gamagrass (Tripsacum dactyloides L.), a wild relative of maize, is widespread over the plains of North and South Americas. To date, it has received universal recognition among breeders as a forage and fodder crop. More than 10 commercial cultivars have already been developed and cultivated in the United States. Eastern gamagrass is a C4 plant as well, characterized by high yield and high feed value of hay. We decided to combine in our research economically valuable qualities of this plant by developing apomictic intergeneric hybrids. This paper presents the results obtained in the process of assessing fodder qualities of apomictic maize × Tripsacum hybrids, where two maize genomes from the lines participating in hybrid selection for F1 seeds were added to the 36 chromosomes of eastern gamagrass. The maize × Tripsacum hybrid forms, produced during a number of years, persistently demonstrated an apomictic reproduction pattern and heterosis in green biomass productivity. Zootechnical analysis of plant samples showed that the hybrids, in which chromosomes of the lines used in commercial seed production to obtain heterosis in F1 had been added to the 36 chromosomes of eastern gamagrass, exceeded in their biochemical indicators the plants, in which 20 chromosomes from one of the maize lines earlier used in hybridization at our laboratory had been added. A theoretical estimate of green biomass yield calculated per hectare for the maize × Tripsacum hybrids is about 65 tons.
Soybean: sources from the VIR collection of genetic resources
Authors: Nekrasov A. Y.
Published: April 2020

Soybean is an extremely valuable crop due to its unique biochemical composition, which underpins multifunctional utilization of this crop and high profitability of its industrial and agricultural production. Soybean seeds accumulate up to 45% of high-quality vegetable protein, which is close in composition to the protein of animal origin. Soybean is also of great importance as an oil-producing crop, accumulating up to 28% of oil in its seeds. It is widely used in animal husbandry for the production of maize-soybean silage and haylage. It can also be used as a green manure crop to enrich the soil with nitrogen at the expense of nodule bacteria. High demand and the price make it a highly profitable agricultural crop. It is clear from the above-mentioned advantages that soybean is of great interest to breeders. The Kuban Experiment station of VIR conducts field studies of new soybean cultivars using the practices worked out for leguminous crops at VIR. Three years of research have resulted in identification of promising cultivars, sources and donors of various valuable traits. This article is based on the data obtained from the study of the soybean collection from 2014 to 2016. Accessions k-11385, k-11479, and i-623931 were distinguished for their high yield. The following accessions stood out for their seed productivity per plant: k-1475, k-11472, k-11535, k-11466, k-11478, k-11577, k-11467, and k-11469. The size of seeds was the best in accessions k-11489, k-11491, k-11533, k-11529, k-11537, i-623952, i-623967, i-623980, i-623958, and i-623987. Two accessions appeared noticeable for the height of lower pod attachment: i-623960 and k-11494. All selected accessions can be used in breeding programs as sources of valuable traits.
Individual morphostructural components of yield in black currant cultivars
Authors: Tikhonova O. A.
Published: April 2020

Background. The size of the fruit, its external attractiveness, along with other important characteristics of a variety, have always been important, especially for amateur gardening. Therefore, new cultivars replenishing the gene pool of black currant preserved by VIR, in addition to their main biological and economic characteristics (flowering and fruiting biology features, resistance to abiotic and biotic environmental factors), undergo mandatory testing for the quality of yield. The aim of this study was to assess individual morphostructural yield components in new cultivars added to the black currant collection of VIR.

Materials and methods. The mechanical composition of berries and bunches was analyzed at Pushkin and Pavlovsk Laboratories of VIR in 2013–2015. Forty-one black currant cultivars of various ecogeographic origin were the material for the research. Cv. ‘Peterburzhenka’, listed in the State Register of Breeding Achievements for the Northwestern region of Russia, served as the reference. The research was conducted by conventional methods. Statistical data processing was performed using Microsoft Excel.

Results and conclusions. Studying individual morphostructural components of yield made it possible to identify cultivars with the largest berries, the most stable fruit weight, and bunches containing 8–9 plump berries. The cultivars with the best combinations of the studied characteristics, suitable for large-scale cultivation and amateur gardening in the Northwest of Russia, are ‘Garmoniya’ (k-40677), ‘Kriviai’ (k-42517), ‘Ben Sarek’ (k-41435), ‘Joninai’ (k-43124), ‘Zhuravushka’ (k-40681), and ‘Shalynya’ (k-41988). Correlations between separate morphostructural yield components were identified, such as: fruit weight – fruit diameter (r = 0.92); fruit weight – number of seeds (r = 0.74); bunch length – number of flowers per bunch (r = 0.65), bunch length – number of berries per bunch (r = 0.52).
Polymorphism of monogenic scab resistance loci in apple varieties
Authors: Lyzhin A. S. , Savel’eva N. N.
Published: April 2020

Background. Monogenic scab resistance is an important trait of apple, useful to plant breeders. DNA markers provide a possibility to differentiate apple cultivars according to individual resistance determinants with high reliability and identify promising genotypes. The present study shows the results of the molecular genetic analysis of apple varieties, targeted at the Rvi2, Rvi4, Rvi6 and Rvi8 monogenic scab resistance loci.

Materials and methods. Biological material was represented by apple cultivars of different environmental and geographical origin. Total genomic DNA was extracted from fresh leaves using CTAB methods according to the DArT protocols. The Rvi6 gene was identified with two markers, VfC (STS) and AL07 (SCAR). The presence of the Rvi4 gene was detected with the multiallelic SCAR marker AD13. The Rvi2 and Rvi8 genes were diagnosed with the SCAR marker OPL19.

Results and conclusion. The Rvi6 gene was identified in 54.4% of genotypes, of which 91.9% were heterozygous, and 8.1% (cvs. ‘Svezhest’, ‘Freedom’ and ‘GoldRush’) homozygous dominant for this locus. The marker AD13-SCAR was detected in 25.0% of the studied forms (the putative genotype for the resistance gene is Rvi4Rvi4 or Rvi4rvi4). The marker OPL19-SCAR (Rvi2 and Rvi8 genes) was present in 73.5% of the analyzed forms. At least one of the studied molecular markers was present in the genome of 86.8% of genotypes. The appletree cultivars ‘Kandil Orlovsky’, ‘Krasulya’, ‘Sozvezdiye’, ‘Galarina’, ‘Priam’, ‘Redfree’ and ‘Witos’ are characterized by the combination of markers VfC, AL07-SCAR, AD13-SCAR and OPL19-SCAR in one genotype (the putative genotype for the resistance genes is Rvi2(Rvi8)Rvi4Rvi6rvi6). Cvs. ‘Antonovka zimnyaya’, ‘Antonovka krasnaya’, ‘Berkutovskoye’, ‘Geyzer’, ‘Pamyati Nesterova’, ‘Renet Simirenko’, ‘Terentyevka’, ‘Golden Delicious’, and ‘Telemon’ presumably have a homozygous recessive genotype for the studied resistance loci.
South American species Solanum alandiae Card. and S. okadae Hawkes et Hjerting as potential sources of genes for potato late blight resistance
Authors: Muratova (Fadina) O. A. , Beketova M. P. , Kuznetsova M. A. , Rogozina E. V. , Khavkin E. E.
Published: April 2020

For several decades, wild species of Solanum L. section Petota Dumort. have been involved in potato cultivar breeding for robust resistance to pests and diseases. Potato late blight (LB) is caused by oomycete Phytophthora infestans (Mont.) de Bary, and the genes for race-specific resistance to P. infestans (Rpi genes) have been introgressed into cultivated potatoes by remote crosses and trans- or cisgenesis, first from S. demissum Buk. and, more recently, from other wild species, such as S. bulbocastanum Dun., S. stoloniferum Schlechtd. et Bché, and S. venturii Hawkes et Hjerting (according to the nomenclature by Hawkes, 1990). Most wild species already involved in breeding for LB resistance came from North and Central Americas: series Bulbocastana (Rydb.) Hawkes, Demissa Buk. and Longipedicellata Buk., and some Rpi genes of these species have been already characterized in much detail. Rpi genes of South American species, including the series Tuberosa (Rydb.) Hawkes, have not been sufficiently investigated. Among the latter, this study focuses on the Rpi genes of S. alandiae Card. and S. okadae Hawkes et Hjerting. Four accessions of S. alandiae, one accession of S. okadae and 11 clones of interspecific potato hybrids comprising S. alandiae germplasm from the VIR collection were PCR-screened using specific SCAR (Sequence Characterized Amplified Region) markers for eight Rpi genes. SCAR amplicons of five Rpi genes registered in this study were validated by comparing their sequences with those of prototype genes deposited in the NCBI Genbank. Among the structural homologues of Rpi genes found in S. alandiae and S. okadae, of special interest are homologues of CC-NB-LRR resistance genes with broad specificity towards P. infestans races, in particular R2=Rpi-blb3, R8, R9a, Rpi-vnt1 and Rpi-blb2 (94–99, 94–99, 86–89, 92–98 and 91% identity with the prototype genes, respectively). Our data may help to better understand the process of Rpi gene divergence along with the evolution of tuberbearing Solanum species, particularly in the series Tuberosa.

Published: April 2020

Avena magna Murphy et Terrell (2n = 4x = 28), a tetraploid oat species endemic of Morocco, has a high groat protein content (more than 20%), good resistance to diseases and good adaptability to the Mediterranean edaphic and climate conditions. Moreover, this taxon is morphologically similar to the hexaploid oat species A. sativa and promising for interspecific crosses with A. sativa in order to transfer the domestication syndrome into it. Four hybridization cycles employing four accessions of A. magna and five Moroccan hexaploid oat cultivars of A. sativa were accomplished to domesticate A. magna. Morphological characterization and cytogenetic analysis of derivative hybrid seeds were made to determine their ploidy level and select the seeds with 2n = 28. The overall combinations yielded 81 hybrid plants with 2n varying from 28 to 29, with 58% having 2n = 28, and pollen fertility over 85%. However, 27 hybrids yielded a seed set ranging from 20 to 80%. Selected hybrid plants were subjected to pedigree selection in the field until they reached the 8th generation and assessed for agronomic performance. Three domesticated lines of tetraploid oat A. magna were selected for their good disease resistance. Analysis of groat protein content in the selected hybrids using the Kjeldahl method showed that it was 2 to 3% higher than in their parents.

Authors: Telezhinskiy D. D. , Kotov L. A. , Makarenko S. A. , Tarasova G. N.
Published: April 2020

The Middle Urals is a region of risky agriculture. Apple cultivars of more southern origin are usually unpromising due to insufficient level of hardiness, so there is a need to develop and deploy local apple-tree cultivars. The staff of Sverdlovsk Horticultural Breeding Station released a new apple cultivar, ‘Sverdlovchanin’. This cultivar is notable for high winter hardiness, productivity (average yield is ca. 18.0 t/ha), and low fruit shedding rate at harvest maturity. Its fruits are beautiful, uniform, yellow, roundish, weighing 110 g (maximum 205 g), with a very good sweet and sour dessert flavor. The ripening time under the conditions of the Middle Urals is usually late September, and fruits can be stored until the end of February. The author of this cultivar is L. A. Kotov The apple cultivar ‘Sverdlovchanin’ was included in the State Register of Breeding Achievements of the Russian Federation in 2018.
Passage through phenophases by milkvetches introduced into the environments of the Kulunda Steppe
Authors: Kornievskaya T. V.
Published: April 2020

Background. Recently, more and more attention has been paid to the study of plant phenology in the context of the global climate change. By now, the question of how climate factors affect the phenophases of plants has not yet been fully investigated. Accurate forecasts for biological responses of plant species to climate change require profound understanding of the impact produced by meteorological factors on plant phenology.

Materials and methods. The research was targeted at Astragalus L. spp. introduced into the dry steppe areas of the Kulunda Plain. Meteorological indicators were selected for agrometeorological description of the plant introduction site to assess its hydrothermal conditions. The Pearson correlation coefficient was used to identify the level of correlations between the studied parameters.

Results. High air temperature shortened the growing season of Astragalus cicer L., but lengthened its flowering and fruiting phases. An increase in relative air humidity shortened the flowering in A. cicer. Meteorological indicators did not significantly affect the duration of the phenophases in A. sulcatus L. For A. onobrychis L., an increase in the average relative humidity reduced the budding phase, while an increase in the average and maximum air temperature and an increase in the amount of precipitation increased the flowering period. A decrease in air temperature and average relative humidity, and an increase in the total precipitation lengthened the duration of fruiting in A. onobrychis. Increased average temperature and humidity reduced its fruiting phase.

Conclusion. A. sulcatus is tolerant to the dry steppe environments. The phenophases of A. cicer and A. onobrychis are more responsive to changes in meteorological indicators. In A. onobrychis, the fruiting phase is susceptible to the combined impact of climate factors. The limiting factors for A. cicer are relative humidity, total precipitation and mean temperature during the growing season.

Por volta dos anos setenta começou a surgir muitos trabalhos com o objetivo de estudar o perfil subjetivo dos alunos, afirmando que o professor deve potencializar a forma de ensino a fim de atingir a maior parte de seus alunos, integrando outras metodologias junto à aula expositiva e dialogada. Fourez (2006), Gil-Perez e Vilches (2005) destacam que o processo de ensino no Brasil está em uma situação muito preocupante, e isto é comprovado por pesquisas nacionais, internacionais e indicadores de desempenho. Buch e Schroeder (2013) complementam esta fala destacando que pesquisadores elencaram alguns aspectos que levam a este fenômeno, sendo estes, a falta de capacitação de professores, as más condições de exercício do magistério, e também a falta de interesse dos estudantes em querer aprender. Assim, Pozo e Crespo (2009) afirmam que são nestes momentos difíceis que podemos refletir e propor alternativas para garantir um ensino mais significativo. Logo, ao principal objetivo deste trabalho coube analisar o quão eficiente pode ser a integração de outras metodologias frente ao ensino e aprendizado de matemática, utilizando ferramentas digitais, como o Excel, e também jogos didáticos. Essa pesquisa consistiu em analisar o desempenho de trinta e cinco alunos de uma turma de sétimo ano de uma escola pública, apoiado no conteúdo referente ao tópico Tratamento da Informação. Foi medido o desempenho dos alunos após uma sequência didática usando o método expositivo e dialogado, e também após uma segunda sequência didática usando recursos alternativos nas práticas de ensinagem. Os resultados obtidos neste trabalho mostraram que a utilização de recursos tecnológicos, assim como a utilização de jogos, melhorou substancialmente o índice de desempenho dos alunos, uma vez que a média de acerto as questões propostas aumentou formidavelmente, concluindo assim, que jogos pedagógicos e o uso da tecnologia da informação podem ser integrados em aulas de matemática para melhorar o desempenho dos alunos no entendimento dos conceitos e conteúdos matemáticos.

Published: April 2020

Apesar de publicado em 1927, o Papiro de Rhind é um documento de aproximadamente 1620 a.C. e que possui problemas práticos na Matemática, isto é, trata-se de questões referentes ao contexto do Egito na Idade Antiga em que podem ser solucionados pela Matemática, pois eram pautavam sobre aritmética, trigonometria e geometria. Este presente artigo é uma intervenção pedagógica da inserção do Papiro na sala de aula da Educação Básica atrelado a uma proposta metodológica de ensino. Como este trabalho pauta-se sobre uma sessão didática realizada no munícipio de Canindé, nos anos finais do Ensino Fundamental, necessita-se abordar as habilidades previstas na Base Nacional Comum Curricular – BNCC, o que se relata neste texto ter sido uma preocupação do docente atrelar a atividade com documento histórico original e a BNCC. Tem-se como justificativa a dificuldade da utilização de textos históricos originais da Matemática em sala de aula. Como objetivo de pesquisa, propõe-se investigar o Papiro de Rhind na sala de aula por meio da metodologia de ensino Sequência Fedathi, que norteia os aspectos didáticos docentes em sala de aula. O trabalho apresenta detalhes de diálogos realizados entre professor-aluno e aluno-aluno, como também uma solução dada por um grupo de discentes, como foi realizada a sessão didática para o ensino de Potência. Tem-se nas considerações finais a dinâmica que a SF proporcionou em sala de aula, pois os alunos foram sujeitos ativos na construção de uma solução para o problema proposto, como também exemplificaram no momento em que o professor sintetizou o conteúdo abordado. Por fim, mostrou-se ser possível a utilização de textos históricos originais em sala de aula da Educação Básica.

Levando em consideração a influência do domínio afetivo no aprender e, em especial, no aprender matemática, desenvolveu-se esse estudo que teve por objetivo investigar percepções e sentimentos de alunos do Ensino Médio em relação à matemática expressas por uma turma desse nível de escolaridade de uma instituição  pública de um município da região central do estado do Rio Grande do Sul. Para tal, aplicou-se um questionário estruturado, composto por quatro questões, a vinte e oito estudantes concluintes dessa etapa da Educação Básica. As questões propostas relacionaram um possível caráter excludente da disciplina, as experiências pessoais a partir de metáforas e os sentimentos relativos ao conteúdo baseado em um desenho. Após a coleta dos dados, esses foram analisados tendo em vista uma abordagem interpretativo-descritiva, na qual foram compostas categorias à posteriori. Os resultados evidenciaram que saber matemática, na percepção dos estudantes, se relaciona principalmente às aplicações de conceitos matemáticos em atividades cotidianas. Mostraram também que em se tratando de experiências passadas, os alunos evidenciaram metáforas bastante negativas à essa disciplina, comparando-a majoritariamente a animais com características de causarem medo ou desconforto. Por fim, ao serem solicitados a desenharem como se sentiam em relação ao componente curricular em questão, os alunos apresentaram imagens com sentimentos ruins em sua maioria, destacando-se as intersecções entre visões boas e más dessa disciplina. Dessa forma, conclui-se que, ao conhecer essas percepções e sentimentos em relação à matemática dos estudantes, os professores podem elaborar estratégias buscando romper com uma visão negativa perante a disciplina, além de buscar melhorar a aprendizagem dos mesmos.

Este estudo, é uma proposta de atividades didáticas envolvendo o conteúdo de sequências numéricas por meio dos números triangulares, partindo do estudo documental de pesquisas já realizadas sobre o tema. A sequência numérica é um assunto que muitos alunos têm dificuldade, principalmente porque eles não conseguirem enxergar o infinito, muito menos, a soma de elementos infinitas vezes. Por esse motivo, esta pesquisa foi desenvolvida para o professor ter um novo apoio pedagógico, tendo como objetivo conhecer as contribuições dos números triangulares para o estudo de sequências numéricas por meio de atividades didática no ensino médio. Através de atividades que utilizam a história da matemática e material manipulável no estudo dos números triangulares. Para produção deste estudo, foram utilizados a pesquisa documental e bibliográfica, pois analisamos estudos sobre os números triangulares. Dentre elas, estavam a história da matemática, os conceitos matemáticos dos números triangulares, e as que trabalhavam com materiais manipuláveis. Portanto, foram elaboradas atividades, que auxiliarão os professores no ensino de sequência numérica. Podendo ser realizadas com a sequência didática ou com as atividades orientadoras de estudos.

A Atenção Primária em Saúde é considerada o principal modelo de organização da atenção à saúde e a via de acesso mais adequada a população. Este nível de atenção tem a capacidade de responder de forma contínua, sistematizada e equânime, à maior demanda de saúde no âmbito individual e coletivo. O Brasil assume compromisso com uma proposta de vigilância em saúde voltada para a infecção humana pelo SARS-CoV-2 (infecção respiratória pelo novo coronavírus), apoiada pela consolidação de informações da OMS e novas evidências técnicas e científicas. Com a rápida disseminação do vírus os serviços da APS tornam-se essenciais para o enfrentamento do agravo. Mas o impacto da mudança no financiamento da Atenção Primária em Saúde, pode gerar sobrecarga à rede de atenção à saúde, que vive em um panorama marcado por instabilidade e precarização das relações de trabalho.

Published: April 2020

This study investigated the physicochemical properties, sugar and organic acid profiles of 21 grape juice and 3 sour grape juice samples in Turkey. The pH, acidity and soluble solids were ranged from 2.64 to 4.19, 3.58 to 30.75 g L-1 and 5.45 to 25.45 °Bx, respectively. The turbidities varied between 1.59 and 109.50 NTU and the lowest value was in the Sultani Çekirdeksiz sour grape juices. The Denizli Karasi sample had the highest color index. The tartaric and malic acid amounts of the samples ranged from 0.53 to 13.16 g 100-1 g-1 and 0.45 to 30.80 g 100-1 g-1, respectively. The major acid was malic acid in the sour grape juice samples and tartaric acid in the grape juice samples. For all samples, glucose and fructose constituted a great part of total sugars. The glucose, fructose and total sugar contents changed from 28.45 to 48.00 g 100-1 g-1, 15.88 to 48.75 g 100-1 g-1 and 53.67 to 97.27 g 100-1 g-1, respectively. The highest sugar content was observed in Kara Erik and the lowest in Yediveren. As a result; some physicochemical characteristics, sugar and organic acid contents of the examined 24 grape juice samples were revealed by the current work.

Schools are heralded by some as unique sites for promoting racial equity. Central to this characterization is the presumption that teachers embrace racial equity and teaching about this topic. In contrast, others have documented the ongoing role of teachers in perpetuating racial inequality in schools. In this article, we employ data from two national data sets to investigate teachers’ explicit and implicit racial bias, comparing them to adults with similar characteristics. We find that both teachers and nonteachers hold pro-White explicit and implicit racial biases. Furthermore, differences between teachers and nonteachers were negligible or insignificant. The findings suggest that if schools are to effectively promote racial equity, teachers should be provided with training to either shift or mitigate the effects of their own racial biases.
Selected Sacred Music from the Ospedale della Pietà
Authors: Porta Giovanni
Published: April 2020

Giovanni Porta held the highest post in the music school at the Pietà, maestro di coro, from 1726–37, and his music was a regular feature at the church services. He is the earliest composer represented in the partbooks for whom adequate sources survive. The partbook collection from the Ospedale della Pietà, the “Fondo Esposi,” now held at the Conservatorio di Musica Benedetto Marcello in Venice, Italy, is the working musical repertory used by the foundlings of the Pietà in the eighteenth century. The significance of music in the daily life at the Pietà gave the institution its designation as an “orphanage-conservatory,” and much of its history is preserved in the music. The availability of Porta's music helps to define aspects of a distinctive style and musical tradition followed at the Pietà at the time of Vivaldi.

As one of the classic Javanese batik, the Kawung batik motif contains philosophical values â€‹â€‹that teach life guidelines for humans, such as gratitude, religiosity, respect for nature, and togetherness. These philosophical values â€‹â€‹are still relevant to the current situation, so it is interesting to be used as a source of ideas for the creation of contemporary paintings. This article is the result of research that aims to describe the philosophical values â€‹â€‹of the Kawung batik motif as a source of ideas and the process of creating contemporary batik paintings. The method is descriptive qualitative with the type of art creation research. The stages include: 1) gathering information about the Kawung batik motif, 2) exploring ideas based on the philosophical meaning of the Kawung batik motif, 3) making a design sketch, 4) realizing the sketch into a painting, 5) describing the shape of the painting created. The results of this study are 1) a description of the philosophical meaning of Kawung batik motifs, 2) a description of the process of creating contemporary batik painting works, 3) a description of the forms of contemporary batik painting works that contain philosophical values â€‹â€‹of Kawung batik motifs. The results of this study indicate that the batik painting produced has a local character and represents the soul of the times. Thus, it is evident that the local wisdom values â€‹â€‹of traditional culture can be developed and harmonized with contemporary culture.

Introduction: The COVID-19 pandemic represents an increase in consultations and demand for care in health services; however, health personnel could be exposed to greater risks than the general population, if adequate protection measures are not taken. Objective: To determine the personal protection needs of health professionals during the COVID-19 pandemic. Materials and methods: The preliminary results of a descriptive cross-sectional study are presented in which an online survey collected information regarding the needs of personal protection elements (PPE) in 521 people in the health area, linked to 4 third level care centers in Cauca department. Results: 47.1% of participants reported not having received training regarding the use of PPE after the establishment of the state of emergency in Colombia. 37% report feeling insecure or not knowing anything about PPE and 64.5% reported having to buy personal protection items, mainly face masks (surgical mask) and N95 mask. Conclusions: Although this is a study with non-probability sampling, the results show that it is necessary to immediately increase coverage with respect to the PPE of health personnel, while promoting training in the use of these. Lack of this coverage could favor the desertion of health personnel, affecting their own health and the health of the general population.
