Gynogenesis is the only way to form haploid embryoids, which underlies the technology of creating doubled haploids of Beta vulgaris L. plants of the species, including red beet. The composition of nutrient media has a significant influence on embryo- and callusogenesis in the culture of isolated ovules and the final yield of regenerated plants. In early works, researchers studied the effect of growth regulators, organic components, the consistency of nutrient media. In standard protocols for the culture of sugar beet isolated ovules, agarose, agar, and phytagel are gelling agents for the nutrient medium. At the same time, there are no studies of the use of various gelling agents’ effectiveness compared to each other. During the cultivation of isolated red beet ovules,only agar was used to gelate the nutrient medium. At the same time, gelling agents and their concentration determine the mobilization of nutrient media; have various effects on explants, their vitrification, and the quality of regenerants. The selection of optimal gelling agent of the nutrient medium for cultivating isolated beet ovules can increase the yield of embryoids, callus, and regenerant plants and is relevant for research. In this work, we have studied the effect of gelling agents (agar, agargel, phytagel, and agarose) in the nutrient medium composition on embryo- and callusogenesis in the culture of isolated ovules of red beet (Beta vulgaris L.). Isolated ovules were cultured on MS nutrient medium supplemented with 200 mg/l BAP, 500 mg/l IAA, 60 g/l sucrose, and the following gelling agents: agar – 7.5 g/l; agarose – 6 g/l; agargel – 4 g/l; phytagel – 2 g/l. A Petri dish with 20 ovules represents repetition; the researchers experimented with 22 replicates. The researchers observed a higher yield of embryoids and callus when studying the effect of nutrient media gelling agents on the formation of embryoids and callus in the culture of isolated ovules in media containing phytagel and agarose. In contrast, in media containing agar and agargel, ovules formed callus and embryoids with a lower frequency, while agar has a more negative effect than agargel.

The article presents data on the estimation of the number of aphids on the territory of the field station of Russian State Agrarian University – Moscow Timiryazev Agricultural Academy for 2016–2017 on varietal samples of the spring triticale collection of the Department of Genetics, Breeding and Seed Production. The assessment was carried out on two physiological phases of plants – tillering and milk ripeness. At the tillering stage, bird cherry-oat aphid prevailed, and at the stage of milk ripeness, large grass aphid prevailed. Common grass aphids and barley aphids were also found. Based on the data obtained, the authors found the difference in the population of cultivars, which may indicate resistance to a particular type of aphid. In 2016, the following varieties were identified at the tillering stage: C236, C224, V10 286, P2–16–5, 09305, P2–16–19, C248, C254, and 09020, 08880, 09306, Khlebodar Ukrainsky, Grego, Dublet, 131/7, V17–5–49, which were less populated. At the stage of milk ripeness, the following varieties are S1728, C236, C248, 131/7, Dublet. In 2017, the following samples with the most significant number of aphids can be used for further selections: C254, Ril130R-22–2, and a large margin C250 (the tillering stage). In 2016, these genotypes were in the group of medium – and low populated. The highest population of aphids was observed in four genotypes: Merezhko Memory, C247, C257, V10–286 (grain filling stage). The identified sparsely populated varieties are of interest for further research in terms of variety resistance, and the most populated ones are used as sensitivity standards.

Clonal micropropagation of grape varieties of interspecific origin Moscow white (Vitis amurensis Rupr. × Vitis vinifera L.) showed that on the 40th day of the animation stage, a monopodial type of branching is typical for micro-plants, and there is no diaphragm in all nodes of micro-shoots. On the 120th day of growing in containers, the researchers revealed that the nodes of the plant shoots, from the 1st to the 6th, have a monopodial branching type. Parenchymal cells which form an incomplete diaphragm are present in the seventh node. A fully formed diaphragm appears from the eighth node, and the branching type switches to a sympodial-monopodial one.

The phytopathogenic bacterium Acidovorax citrulli is included in the quarantine lists of many countries, including the unified list of quarantine objects of the Eurasian Economic Union. The control of the introduction and spread of the quarantine organism into the territory of Russia is carried out through laboratory diagnostics. Diagnostic methods should ensure quality and the high speed of product health testing. The study aimed to use new methods for the detection and identification of A. citrulli and to optimize the laboratory diagnostic scheme. In the course of the work, cucumber seeds with an infectious load were prepared and tested. Testing was carried out according to an optimized diagnostic scheme using methods not previously used to diagnose A. citrulli. At each stage of work with samples, the time spent was recorded. The researchers tested the prepared infected seeds at the first stage using the standard qPCR method and then the qPCR method PAS F/R, PAS P, which had not previously been used to diagnose A. citrulli. The new qPCR test PAS F/R, PAS P showed stable results at testing each sample in a row of each replication. The sample enrichment method was successfully applied, not previously used in diagnosing A. citrulli. The use of the method made it possible to separate samples containing live target bacteria from those containing only A. citrulli DNA within 2.5 days. After enrichment, the isolation and identification of the A. citrulli culture from the samples were successfully carried out. Based on the data obtained as a result of this study, the scheme for detecting and identifying the causative agent of bacterial fruit blotch of cucurbits was optimized. The proposed scheme will reduce diagnosing a dangerous quarantine organism from four weeks to one week.

Despite significant achievements in the agricultural sector, the problem of mastitis in sheep continues to be one of the most relevant for veterinary science and practice. Therefore, in current conditions, the solution of diagnosis, therapy, and prevention of this disease is urgently needed. The article presents morphological and biochemical parameters of sheep blood in acute serous mastitis. The research was at “Belozernoe” of the Salsk district of the Rostov region, with a total number of sheep of 956 heads. The complex of clinical and laboratory studies was performed on 12 sheep of the Sokolskaya breed (at the age of 2–3 years), with signs of acute serous mastitis. The control group consisted of clinically healthy sheep aged 2–3 years. In a clinical study of sheep, the researchers focused on the general condition, body temperature, heart rate, respiration, and scar movement in two minutes. The study has shown that in serous mastitis, there is an increase in body temperature to 40.5–40.9°C, pulse rate to 95 beats per minute, and respiration – up to 40 respiratory movements per minute. The frequency of scar contractions was 3–6 times in two minutes. During the clinical examination, the affected half of the sheep’s udder was enlarged 3–4 times in volume, compacted, the skin is tense, and the breast nipple is slightly enlarged and flaccid. The supravyminal lymph node enlarged in volume by 1.5–2 times, and the sick sheep reacted painfully to palpation. At the beginning of the inflammation, milk from the affected lobe had a white color. When the disease passed into a more severe form, it became watery with an admixture of blood. As a rule, severe mastitis was acute. There was a partial loss of appetite. The researchers established that acute serous mastitis in sheep is clinically manifested by depression, subfebrile or febrile increase in body temperature, moderate tachypnea, and tachycardia. In the blood of sheep with acute serous mastitis, there is a significant decrease in the number of red blood cells and hemoglobin. A pronounced neutrophilic leukocytosis develops with a simple shift of the regenerative nucleus to the left against the background of moderate eosinophilia. In the blood serum of sheep with acute mastitis, dysproteinemia is detected, characterized by a moderate decrease in albumin concentration and a significant increase in the content of alpha-globulins. In the blood serum of sick sheep, the concentration of iron also significantly decreases, and the content of copper increases.

Freedom of speech on social media is sometimes inappropriate with the ethics of communicating and has led to cyberbullying. Instagram is the most commonly used social media in cyberbullying. Cyberbullying needs to be minimized because it has many adverse effects. One way that can be done is by identifying cyberbullying comments so those comments can be deleted automatically. The method used in this study is text classification using Support Vector Machine (SVM) algorithm with the application of Binary Particle Swarm Optimization (BPSO) optimization method as features selection. The study aims to build a cyberbullying comments classification model and compare the classification model performance with and without the application of features selection. The experimental results showed that modeling with SVM produces a reasonably accurate classification performance over 72% for all classification performance on each C. The application of BPSO for features selection can improve classification performance by increasing accuracy and specificity. However, the model without features selection on C = 0,1 is chosen in this study case because it has the highest sensitivity with good accuracy and specificity that can detect cyberbullying comments more accurately.

Lemongrass (Cymbopogon flexuosus) is an important perennial aromatic plant and natural source of citral that is used in the preparations of variousperfumes.In the present study, eight lemongrass cultivars were evaluated for growth, herbage, and essential oil yield during 2018-2019 inthe southern region of Karnataka, India. Results revealed that significant differences were noticed in the growth and yield parameters of eight lemongrass cultivars studied. The plant height and the number of tillers varies, ranging from 108.47-136.75cm and 38.13-47.60, respectively. Significantly higher herbage yield (t/ha/year) was recorded in CIM-Shikar (24.25), followed by Krishna (22.50) and CKP-25 (20.72). The lowest herbage yield wasrecorded in the Cauvery cultivar. Essential oil content varied from 0.70-1.35% (v/w) and essential oil yield varies from 133.56- 302.40 kg/ha/ year in different cultivars. The amount of citral varied from 2.20% to 88.14% among eight lemongrass cultivars. The varieties arranged according to the citral content as follows, Cauvery (88.84 ± 0.99) >Nima (88.57 ± 0.70) >CIM-Shikar (84.97 ± 4.08) >OD-19 (85.90 ± 0.59) >CIM-Suvarna (82.53 ± 1.10) >CKP-25 (81.84 ± 0.30) >Krishna (79.26 ± 0.44) >CIM-Atal (2.15 ± 0.07). CIM-Atal was superior in geraniol (88.92 ± 1.00%) compared to citral (geranial and neral) content among lemongrass cultivars studied; this cultivar may be a partial replacement/ substitute for geraniol rich essential oil-bearing plant in the future. Overall, cultivar CIM-Shikar was superior to other cultivars in terms of essential oil yield (302.40 kg/ha/year) and superior in citral content (84.97 ± 4.08).

Background: Adherence of exercise and physical activity leads to long term physical problems. Objective: The objective of the study was to identify factors leading to adherence to daily exercise among elderly people of the city of Dhaka. Methodology & Materials: It was a cross-sectional study conducted among the elderly population of Dhaka city at one point in time. According to the inclusion and exclusion criteria, 120 respondents were randomly selected. A pretested, modified semi structured questionnaire was used to collect the data. Result: According to our study, the mean age of the respondents was 71.69 ± 4.052 years, with a range of 65 -75 years and above. The male to female ration was about equal (56.7%). The poor (33.3%) and lower middle class (28.3%) respondents were more likely to engage in daily exercise. Nearly half of the respondents were a higher secondary pass and a housewife who adhered to regular exercise. Near about 61.7% of the respondents were not given data regarding daily exercise while 45% avoid daily exercise as a result of physical discomfort. The presence of family demotivation also contributes to adherence to exercise, as about 27% of respondents reported being demotivated from daily exercise and 73% reported being committed to daily exercise. Laziness was also associated with adherence to exercise, as 80% reported skipping daily exercise. Physical illness is most common cause of adherence to exercise regularly near about 71.7% felt this problem. Different types of disease condition lead to adherence to exercise like joint pain, weakness, breathlessness, palpitations, and weakness. 31.7% of respondents felt adherent to daily exercise due to joint pain, whereas 1.7% were adherent to daily exercise due to physical impairment. Approximately 33.3% of the respondents considered adherence to daily exercise to be influenced by their exercise environment. In general, 66.7% of the respondents do not continue regular exercise because of a lack of adequate exercise fields. 20% of the respondents get up early in the morning and exercise regularly. The majority of respondents, 80%, did not do regular exercise due to this problem. Regular daily long- term exercise is difficult for elderly people due to different reasons. Nearly 40% of respondents continue to exercise above 1 hour daily. In this study, there was a statistically significant association between Family Motivation and Gender, where p = 0.002, Physical Problem with Gender, where p = 0.04, Physical Problem with skipping of daily exercise, where p = 0.042, and Physical Problem with waking up early in the morning, where p = 0.05. Conclusion: Physical exercise is more common in elderly due to different factors. Promoting physical exercise and encouraging daily participation may reduce adverse health outcomes.

Published: February 2022

The progress of Greater Mekong Sub-region (GMS) is presumed to pose challenges and implications for Indonesia. This study has the aim to investigate the impact of the recent development of sub-regional cooperation and cross-border economic development within GMS on Indonesia’s industrial development. Using qualitative methods, this study analyzed some variables, i.e., the background of GMS cooperation, infrastructure and investment progress, and Indonesia’s related economic policies and development. Data and information were collected from many sources (i.e., statistical databases, articles, newspapers, websites, un- and published documents, etc.) and presented qualitatively. This study found that GMS economic cooperation and development have lessons learned and implications for the industrial development in Indonesia. The efficiency of the service sector within GMS was contributed by the successful implementation of policies on infrastructure development since the beginning of the 1990s. The flying geese behavior and industrial fragmentation within GMS were contributed by a different stage of industrial development, different comparative advantage, and improvement of the service sector. The implication of GMS cooperation for Indonesia is the importance of public policy stability, more attractive investment of high-end products in GMS than Indonesia, and potential diminishing of Indonesia’s export.

O estudo da variação da temperatura do ar no meio intra-urbano, vem aumentando, porém, estes estudos ainda são parcos, principalmente, em sítios Sítios de relevo acidentado como os de mares de morros, onde os efeitos locais, tais como sombreamento e brisas são pouco conhecidos. Este trabalho busca compreender a variação da temperatura do ar e sua relação com a mudança da situação sinóptica entre o período de fevereiro de 2017 e janeiro de 2018, para cinco pontos fixos instalados em Ponte Nova-MG, cujas observações foram a partir de registros horários dos valores térmicos horários. Além disso, foi realizado o cálculo do fator de obstrução do céu, que foi correlacionado com os dados de temperatura do ar para os meses considerados representativos das estações do verão, outono, inverno e primavera. Além disso, a variação das diferenças térmicas foi observada de acordo com a atuação dos sistemas sinópticos, segundo a proposta de Borsato (2006). As maiores diferenças foram registradas no intervalo entre 15h00min e 16h00min, correspondendo a 98% das ocorrências. Os maiores valores térmicos observados foram coincidentes com a área mais dinâmica e adensada da cidade, embora os índices de SVF não tenham apresentado alta correlação com os dados registrados indicando haver outros fatores de influência na conformação do microclima local.

One of the great challenges for elementary school teachers involves the inclusion of students with some disability, so the search to develop new teaching-learning procedures must be a constant in the school process. This research aimed to apply a geoiconographic proposal with deaf students enrolled from the 6th to the 9th grade of elementary school, in a public school in the Federal District-Brazil, in this perspective it was envisaged to find the relationships and possibilities of teaching-learning based on three axes, landscape, photogeography and transdisciplinary, as instruments that enhance geographic thinking for deaf students. The methodological procedures involved qualitative research, using semi-structured interviews and field activities. The semi-structured interview made it possible to understand the relationship between deaf students 'belonging to Geography, the didactic resources used in Geography classes, the existing relationships between students' daily lives and Geography classes, and how imagery resources can be considered facilitators in learning of this group of students. The field activity made it possible for students to recognize the different landscapes existing in their city, in order to relate them to concepts and geographical phenomena. Photographic cameras were used to obtain the images, distributed individually to the students. From the images obtained, and using Libras as a language, a didactic intervention was carried out in which the students visualized the photos, constructing / reconstructing their concepts and geographical meanings. This construction process culminated in the elaboration and presentation of banners from the photos obtained by the students for the school community.

O estado da arte é um levantamento que auxilia no processo de investigação científica sobre as temáticas desenvolvidas no âmbito acadêmico. Este artigo tem por objetivo analisar o banco de dissertações do Programa de Pós-Graduação em Geografia da Universidade Federal do Piauí (PPGGEO-UFPI), com propósito de fazer o estado da arte sobre os trabalhos voltados ao contexto da urbanização e os procedimentos metodológicos escolhidos pelos autores sob a luz da obra “A condição Urbana: ensaios de geopolítica da cidade” de Paulo Cesár da Costa Gomes. Os procedimentos metodológicos, utilizados para alcançar este objetivo, relacionam-se aos métodos dedutivo, observacional e estatístico, as pesquisas:  descritiva, quantitativa, bibliográfica, documental e a análise de conteúdo. Os resultados revelaram uma significativa concentração de produções acadêmicas na Cidade de Teresina, contrapondo-se as demais cidades que compõem o estado do Piauí. Por fim, observou-se que as tendências de pesquisa no Mestrado em Geografia abrangem desde a gestão urbana, a análise dos planos, as transformações socioespaciais e socioambientais, até o processo de urbanização em ambientes litorâneos.
Climatologia do regime de chuvas em Campina Grande, PB: modelos e variabilidades
Authors: Almeida Hermes Alves de , Galvani Emerson
Published: February 2022

O Semiárido nordestino é um recorte geográfico caracterizado pela elevada variabilidade no regime de chuvas, sempre associada ao fenômeno da seca. Assim sendo, procurou-se estabelecer as principais características da climatologia da chuva da cidade de Campina Grande, PB, sendo essas determinações os objetivos principais. Dados mensais de chuvas, dos últimos 61 anos, foram cedidos pela AESA, PB, sendo analisados mediantes critérios da estatística climatológica. Utilizaram-se os métodos da anomalia da chuva e de índices de seca meteorológica (anomalia da chuva, padronizado de precipitação modificado e decis), além de análises de dispersão, extremos e tendência. Os principais resultados indicaram que os modelos de regimes pluviais são assimétricos, irregulares, as dispersões temporais são inversamente proporcionais aos valores esperados e a estação chuvosa tem chance de ser seca. As oscilações mensais e anuais dos totais de chuva observadas e as respectivas anomalias indicam que as dispersões são indicativas de variabilidade natural e não de mudanças climáticas. Embora as secas sejam de difícil previsibilidade, os índices de secas meteorológica são eficazes para monitorar as diferentes categorias de seca. Recomenda-se o uso de dois ou mais índices e da comparação entre si a fim de estabelecer a tipologia da seca.

O trabalho teve como objetivo avaliar a presença de dados discrepantes no comportamento da precipitação pluvial acumulada na quadra chuvosa (FMAM) do Semiárido do estado do RN. Para tanto, foram empregadas técnicas tanto Qualitativas (gráficos de Caixa ou Boxplot e de Pontos ou Dotplots) quanto Quantitativas (testes do Escore Z, Escore Z Modificado, Grubbs e Dixon). A partir do emprego de tal arcabouço, não foram identificados dados discrepantes em nenhuma das cinco séries temporais (1998-2017) e estações analisadas. Tal resultado enseja que, apesar de suas diferenças tanto metodológicas quanto em relação aos pressupostos que as sustentam, tais técnicas podem sinalizar para resultados muito próximos (ou mesmo iguais) entre si. Ainda em relação aos resultados, assegura-se que os totais anuais pluviais acumulados na estação chuvosa não apresentaram extremos significativos, sejam eles positivos ou negativos (acima/abaixo do habitual ou do excepcional). Finalmente, entende-se que estes resultados devem ser avaliados com cautela, haja vista que tal “estabilidade” temporo-espacial não necessariamente representa um aspecto favorável, por exemplo, para a gestão das águas – sobretudo, quanto ao abastecimento público – do Semiárido do RN, haja vista que, para este caso, acumulados discrepantes positivos são desejáveis.
Haiti e a alternativa migratória

Published: February 2022

Este artigo objetiva traçar um panorama das migrações haitianas para diversos destinos do mundo, em destaque para o continente americano. Transformado em país mais pobre do continente e imerso em uma contínua crise que mistura instabilidade política, precariedade econômica, ingerência estrangeira e desastres ambientais, o Haiti tornou-se incapaz de prover dignamente a sua população dos direitos humanos mais básicos como saúde e educação gratuitas. Frente a um quadro tão complexo, milhões de haitianos buscam na migração internacional alternativas para a melhoria das condições de vida, inclusive dos familiares que permanecem no país. Com base em um levantamento bibliográfico diversificado, foi possível identificar que há mais de um século a migração internacional vem sendo a saída encontrada por parte significativa da população. No século XXI, frente às restrições de entrada no Norte Global, os haitianos incorporam países da América do Sul como novos destinos.

Objective The purpose of this study was to investigate the effects of depressive symptoms on health-seeking behaviors using the large epidemiological study data of the Korea National Health and Nutrition Examination (KNHANES).Methods Data from the Korea National Health and Nutrition Examination Survey (KNHANES), which is a large-scale national survey, were used in this study. The Patient Health Questionnaire-9 (PHQ-9) was used to assess the depressive state of the participants. Specialized self-reported questionnaires that included questions about health-seeking behaviors were also performed. To examine the relationships between depression and health-seeking behaviors, complex sample logistic regression models with control for covariates were used.Results There was a significant association between decreased health-seeking behaviors and depressive symptoms in adults (odds ratio [OR]: 3.11, 95% confidence interval [CI]: 2.44–3.96). The association was found to be especially strong in males (OR: 2.63, 95% CI: 1.69–4.10) versus in females (OR: 2.49, 95% CI: 1.90–3.27). With regard to age group, younger adults (19–44 years of age) showed the highest OR (OR: 3.07, 95% CI: 2.12–4.45).Conclusion Our findings support the idea that there is a significant association between health-seeking behaviors and depressive symptoms in the Korean population. These results suggest that individuals with decreased health-seeking behaviors could be evaluated for depressive symptoms.
No News is Not Good News: The Implications of News Fatigue and News Avoidance in a Pandemic World
Authors: Fitzpatrick Neill
Published: February 2022

In an era dominated by a constant flow of grim news, news fatigue is becoming more recognized as a serious concern, even a health risk. Around-the-clock reports on the pandemic can seem unavoidable, along with ongoing coverage of political upheaval, climate change, and other major global issues. For some, the weight of the world’s news becomes too much. A 2019 pre-pandemic survey of 12,000 American adults by the Pew Research Center found 66% admitting they were “worn out” by the sheer amount of news available to them. News fatigue can translate into a desire to consume less news in an effort to preserve and protect one’s mental health. A Pew Research Center survey in April 2020 determined 71% of adult Americans say they need to “take breaks from COVID-19 news” while 43% said the news “leaves them feeling worse emotionally”. The World Health Organization addressed the concerns about the impact of the news onslaught in the “Mental Health Tips” section of its website. The WHO offers this advice to the public: “Try to reduce how much you watch, read or listen to news that makes you feel anxious or distressed”. Growing numbers are heeding this advice and reducing their news consumption. Some are opting for no news whatsoever as a means of coping. In May 2020, the Reuters Institute for the Study of Journalism at Oxford University examined the “infodemically vulnerable” in Britain, those who chose to reduce consumption of COVID-19 related news. More than one-fifth of those surveyed said: “they often or always actively try to avoid the news,” with the majority citing the impact on their mood. While mental health concerns appear to be the primary reason behind the increase in avoidance, growing distrust in mainstream media is also cited. While not a new phenomenon, the skepticism surrounding journalism was exacerbated during the pandemic as anti-vaccination advocates and conspiracy theorists questioned the validity and accuracy of the COVID-19 facts shared by news organizations, even governments. In this analysis of research, interviews, news articles, and social media content, I will advance recommendations for journalism researchers seeking to understand these issues. I will also propose strategies for journalists and news organizations seeking to navigate the issues and find solutions to help their embattled profession survive and recover.
