Effects of Regional Income, Race, and Educational Level on Incidence of Diabetes and Heart Disease in Ohio
Authors: Bolchalk James R. , Gupta Sanhita
Published: January 2022

Background: Socioeconomic factors such as income, education, race, age, and weight are thought to be contributing factors for the incidence of chronic diseases such as diabetes and cardiovascular disease. Diabetes and cardiovascular disease are not only serious health complications but also cause significant financial burden to the health care system, both in Ohio and the US. This study seeks to examine the relationship of these socioeconomic factors to the prevalence of these 2 diseases in Ohio using the data available from Behavioral Risk Factor Surveillance Systems (BRFSS). Methods: Fourteen regions in Ohio were analyzed using logistic regression for socioeconomic impacts on diabetes and cardiovascular disease. Data for this study were obtained from the Behavioral Risk Factor Surveillance Systems (BRFSS) for the years 2011 through 2018. Results: Our results indicate that a strong relationship exists between age and weight with both diabetes and cardiovascular disease in all 14 regions of Ohio, as expected. However, the contribution of the other socioeconomic factors, except income and education levels, is less certain. Conclusion: This study suggests that besides promoting public health programs that focus on weight and age, effort should be made to evolve strategies promoting increased levels of income augmentation in the population.
A Comparison of Nonprofit Hospital Charity Care Policies and Community Benefit in Central Ohio to Peer Cities
Authors: Clagg Sarah , Wapner Andy , Klingler Jeff , Schweikhart Sharon
Published: January 2022

Background: Nonprofit hospitals in the United States are required to provide community benefits, including charity care, to receive tax exemption from the federal government. Central Ohio's nonprofit hospitals have agreed to the same charity care policies, which may be unique compared to other communities across the county. The aim of this research is to compare the charity care policies of hospitals in Columbus, Ohio, to their peer cities, investigating if hospitals in similar cities have common shared charity care thresholds and to determine if hospitals in peer cities provided similar levels of community benefit. Methods: Tax data from nonprofit hospitals in 21 cities were collected and analyzed using Microsoft Excel (Microsoft Corporation). City community benefit data was summed and averaged using Excel to create a graphical representation of the data. Results: Only Columbus, Ohio, and Providence, Rhode Island, reported the same charity care thresholds across hospitals. Data demonstrate that Columbus provides less community benefit in dollars to total expenses compared to peer cities; however, this appears to be only true regarding other community benefit excluding charity care. Columbus was near the median among cities examined in regard to percentage of charity care to total community benefit. Conclusion: Results suggest variability in the amount and type of community benefit nonprofit hospitals provide. Central Ohio hospitals have the same charity care thresholds and spent approximately the same in total community benefit however it is not transparent how these funds are utilized. Current federal regulations do not assess whether the community benefits reported are affecting community health outcomes.
Health Disparities Among Sexual and Gender Minority Adults in Ohio
Authors: Albrechta Hannah E. , Katz Mira L. , Roberts Megan E.
Published: January 2022

Background: Many documented disparities associated with health behaviors and access to health care impact the health outcomes of sexual and gender minorities (SGM). The current study aimed to gain insight into the health dispari-ties experienced by SGM adults living in Ohio to obtain data to plan future health-related programs. Methods: A secondary data analysis was conducted using 2018 Ohio Behavior Risk Factor Surveillance System (BRFSS) data. Health behaviors, health care access, and health outcomes were analyzed by sexual orientation (n=11 301) and gender identity (n=11 426) to determine health disparities faced by sexual minority males, sexual minority females and transgender individuals. Results: Significant SGM health disparities in Ohio are related to substance use (ie, binge drinking, current smoking status, e-cigarette use, and marijuana use); poor physical and mental health status; lack of health care coverage; and experiencing COPD, emphysema, or chronic bronchitis (all p < 0.001). In addition, fewer sexual minority females reported being within recommended breast cancer screening guidelines than heterosexual females (p < 0.05). Conclusion: Sexual and gender minority adults in Ohio report disparities associated with several health behaviors and access to health care. These findings may be due to factors at the patient level (eg, experiencing minority stress), provider level (eg, implicit bias), system level (eg, discrimination), and/or society level (eg, lack of legal protections). Study results will be used to plan health campaigns and programs targeted to SGM adults and providers to achieve health equity for the SGM population in Ohio.

The education sector in Indonesia is still colored by various problems. These are caused by several factors, such as the lack of effectiveness of education, the lack of efficiency of learning implementation, and the lack of standardization of learning for students with special needs. This study aimed to develop effective competencies in the identification of and intervention with students with special needs in schools. This study used a quantitative approach with a one-group pre-test post-test experimental design. Material presented in the training sessions included the basic concepts of inclusive education, the characteristics of students with special needs, how to teach students with special needs, and how to make individual learning programs. The instruments used in this study for the purposes of the pre-test and post-test were developed by the researchers based on theories and models. A total of 10 items were used in the instrument. Data were analyzed using the Cohen’s D t-test method, which produced a p-value of 0.843; as this is > 0.05, this indicated that there was no difference between before and after the training. Based on the research and workshops conducted by the researchers, it was found that most teachers lacked the motivation to apply training materials for working with students with special needs, even though the level of teachers’ participation in the trainings was high. The results showed that the trainings were not able to significantly influence the skills of teachers in teaching students with special needs. Therefore, other methods are needed to improve the knowledge and abilities of teachers in supporting students with special needs.

Authors: Utaminingtyas Cholifah , Shanti Pravissi , Prastuti Endang , Tri Harsono Yudi
Published: January 2022

Depressive tendencies describe the extent to which a person experiences symptoms of depression. Depression is defined as a psychological condition in which a person experiences deep negative feelings. The onset of depression symptoms can be caused by several factors, one of which is environmental factors. Family can be an environmental factor that affects the psychological well-being of individuals. Families that do not carry out their roles well can be referred to as a dysfunctional family. Adolescence marks the transition from childhood to adulthood. During this period, individuals have a higher prevalence of depression. The objective of this research was to determine the relationship between family dysfunction and depressive tendencies among adolescents in Malang City. The research was conducted with a correlational quantitative approach. 114 subjects were recruited. Data were collected using the Family Assessment Device General Functioning Scale and the Depression Tendency Scale. The results showed that generally, respondents had moderate depressive tendencies, with a mean score of 94.64. Results related to family dysfunction showed a family mean score of 2.1498. This figure indicated that on average the families functioned poorly. This research revealed that there was a significant positive correlation between the two variables with r = 0.626, where the higher the level of family dysfunction, the greater the tendency for depression.

Authors: Gawandari Farinasari Auliana , Chusniyah Tutut , Suryani Indri , Mardianto Mardianto
Published: January 2022

The purpose of this study was: (i) to determine the psychological well-being in men who have partners; (ii) to examine the gender role conflict in these men; (iii) to determine the effect of gender role conflict on psychological well-being for unemployed men who have partners. This was a quantitative predictive study which used descriptive analysis and simple linear regression with 107 research respondents. The research instrument used was the scale of psychological well-being, with a reliability of 0.841, and the scale of gender role conflict, with a reliability of 0.969. The results showed that 53% of respondents had high psychological well-being and 47% had low psychological well-being. 64% of respondents had moderate gender role conflict and 36% of respondents were of a low level. The R-squared value was 0.03 which indicated that gender role conflict explained 3% of psychological well-being while 97% was influenced by other factors. The findings were statistically significant. Based on these findings, the researchers recommend that unemployed men who have partners should revise their life concept to ensure that they do not seek pleasure by doing negative things or rely on the life they have so far instead of seeking permanent livelihood as this may lead to gender role conflict and negative impacts on the psychological well-being of themselves and their families. It is recommended that future research is conducted to improve the measuring instruments, such as by improving the clarity of the language used.

Psychological Inflexibility Moderates Stress and Loneliness in Depression Among Indonesian College Students During the COVID-19 Pandemic
Authors: Mega Radyani Annisa , Hanna Indra Gracia , Ika Dian Oriza Imelda
Published: January 2022

The COVID-19 pandemic has had a tremendous impact on college students’ mental health. Recent studies have found increased perceived stress and loneliness during the pandemic, which are significant risk factors for depression. However, few researchers have specifically discussed the particular factors that can exacerbate the impact of these risk factors on depression. Psychological inflexibility is said to have an important role in facilitating the development of mental health problems. The current study explored the role of psychological inflexibility in moderating perceived stress and loneliness in depression during the COVID-19 pandemic. A cross-sectional study using an online survey was conducted to assess college students’ sociodemographic information, perceived stress, loneliness, and depression during the COVID-19 pandemic. A total of 941 Indonesian college students (age range = 18-39 years old, 74% female) were analyzed using correlation analysis and SPSS macro PROCESS moderation analysis. Several sociodemographic factors such as age, marital status, previous mental health record, education level, perceived impact of COVID-19, income, and financial status were significantly associated with depression and psychological inflexibility, and were thus controlled as covariates. As predicted, higher psychological inflexibility was associated with higher perceived stress, loneliness, and depression. Results showed psychological inflexibility elevated the effect of both perceived stress and loneliness on the depression level. These findings support previous literature regarding the significant role of psychological inflexibility in moderating the development of depression, especially during the COVID-19 pandemic. Based on the findings, it is recommended that alternative interventions are implemented to inhibit the development of depression by decreasing psychological inflexibility, while considering sociodemographic factors.

Published: January 2022

The COVID-19 pandemic has affected many facets of life. The rising usage of the internet, particularly social media platforms, is one of them. Individuals who use the internet more frequently may develop an internet addiction. This study aimed to investigate the relationship between stress and internet addiction in college students. This study utilized a survey-based correlational quantitative approach. The sample consisted of 81 students from the State University of Malang. The instruments utilized in this study were the Perceived Stress Scale-10 modified for COVID-19 to measure stress related to the COVID-19 pandemic, and the Internet Addiction Test to measure internet addiction. Data were analyzed using product moment correlation techniques. The study’s findings revealed a substantial positive relationship between stress from the COVID-19 pandemic and internet addiction in college students (r = 0.333; p = 0.002). This implies that the higher the stress level related to the COVID-19 pandemic experienced by an individual, the higher the tendency for internet addiction.

Authors: Khairul Anam Muhammad , Hitipeuw Imanuel
Published: January 2022

One of the problems that often occurs when completing a thesis is academic procrastination. This can result in delayed graduation, which is not desirable in our education system. Loneliness can affect students’ academic performance. Globally, loneliness has been increasing as a result of the COVID-19 pandemic. Students who are working on their thesis are vulnerable to loneliness. This research aimed to determine whether there is a correlation between loneliness and procrastination among psychology students who are working on their thesis. This research used descriptive quantitative methods, and data were obtained from online questionnaires that were distributed to 55 psychology students working on a thesis at the State University of Malang. Participants were recruited through convenience sampling. The research instruments used were two modified scales: the Loneliness Scale created by de Jong-Gierveld and Kamphuls (α = 0.796) [1] and the Academic Procrastination Scale created by McCloskey and Scielzo (α = 0.905) [2]. The data were analyzed with the Pearson Product Moment correlation test. The results showed that there was a weak but significant and positive correlation between loneliness and academic procrastination (r = 319; p < 0.05). Most research subjects had a moderate level of loneliness and academic procrastination.

French and Swiss banks as initiators of implementation and use of Crowdfunding Systems
Authors: Dziuba Dariusz T.
Published: January 2022

Purpose of the Study: The subjects of the considerations are initiatives to implement or use the method of online crowdfunding by banks. The focus was on such implementations in France and Switzerland, i.e. countries with a relatively large number of such projects. The presented research identifies crowdfunding platforms and (depending on access to data) determines the size in terms of value of the analyzed market sub-segment and its specificity. This work is a continuation of a series of author`s publications aimed at examining the crowdfunding market sub-segment of banks in Europe.
Methodology: Crowdfunding platforms in individual French and Swiss banks were identified. Data was obtained from internet resources, supported by, inter alia, available publications. The final data was obtained directly from the websites of the analyzed financial institutions (or platforms), or they were aggregated, or the data was estimated on the basis of partial information. The research was carried out in October and November 2021, with data verification as of November 30.
Main Findings: The article explores a specific market segment in France and Switzerland - banks implementing or using crowdfunding platforms. The scope of implementation of such systems was determined by identifying the individual analyzed financial institutions. The value of accumulated financial resources (capital) and the scope of project implementation were measured, distinguishing the size of the market sub-segment under study. The examined systems collectively obtained a relatively large amount, over EUR 4326 million.
Applications of the Study: The presented article concerns the applications of the crowdfunding method in financial institutions (French and Swiss banks). This implies considerations in several scientific fields, incl. economics (the possibility of measuring the market segment), business informatics (electronic platforms; human-computer interactions).
Novelty / Originality of this Study: The scientific literature on the use of crowdfunding in banks, and especially the measurement of the size of this market segment, is almost non-existent, it is only fragmentary. The separation in this article of the size of the crowdfunding sub-segment in French and Swiss banks, although partial, seems prospective, as it allows for further research in this area.
The cooperation agreements within the belt and road initiative: The european common commercial policy at crossroads
Authors: Martínez San Millán Carmen
Published: January 2022

To carry out Chinese investments in third countries under the Belt and Road Initiative, the China is currently concluding numerous cooperation agreements called Memorandums of Understanding with its objective States, including European Union Member States. These Memorandums of Understanding are international agreements, but not international treaties as such, which implies that these documents may not lead to rights and obligations under International Law. However, every Memorandum of Understanding signed between China and a European Member States should be interpreted in accordance with European Law. The problem is that Member States are presumably violating different instruments of this legal framework as well as the European Union Common Commercial Policy, which is an exclusive competence of this international organization, if we interpret that these cooperation agreements are masking free trade agreements. This paper aims to analyse this possible interpretation and its consequences for the European Union, as these agreements entail a weakening of the European trade and investment power and put the European Common Commercial Policy at crossroads.

Authors: Sanchez Luengos Itsasne , Lucas Jiménez Olaia , Peña Lasa Javier , Ojeda del Pozo Natalia , Ibarretxe Bilbao Naroa
Published: January 2022

Parkinson’s Disease (PD) is mainly known for its motor symptoms. However, it can also involve the impairment of certain cognitive functions (memory, attention, visuospatial skills, etc.), and is associated with a lower quality of life among people with PD and those closest to them. As the disease progresses, there is a greater need for care, which is generally provided by informal caregivers. This briefing is aimed at organisations and specialists interested in applying a combined intervention of cognitive rehabilitation for people with PD and psychoeducation for their family caregivers at their centres. The goal is to improve the cognitive functions and quality of life of people with PD and their families. Involving families can provide an integrated approach to the rehabilitation process and strengthen the benefits for people with PD, while at the same time offering strategies for fostering better quality of life among caregivers.

Published: January 2022

La iniciativa Bizkaia Orekan Sakonduz es una iniciativa colaborativa liderada por la Diputación Foral de Bizkaia y en cuyo origen participó Orkestra-Instituto Vasco de Competitividad. Nace de la necesidad detectada en 2014 a través de un diagnóstico de competitividad de que las políticas de promoción económica respondan a la realidad de un territorio heterogéneo y diverso desde el punto de vista no solo de su tejido productivo, sino también desde sus retos de competitividad. Para ello, se puso en marcha un modelo de gobernanza multinivel con la involucración de personas de organizaciones claves a nivel local y comarcal. A lo largo de los últimos años se han generado dinámicas colaborativas que han permitido profundizar, por una parte, en las capacidades de estas personas de entidades locales y comarcales como facilitadoras de avances en los retos para la competitividad territorial; y por otra, en generar proyectos conjuntos en torno a retos comunes. La necesidad de articular una herramienta de apoyo a estos proyectos ha culminado con el lanzamiento de un programa de ayudas en 2020.

Significance of the EU funds in regional development on the example of NUTS-3 units in Poland
Authors: Spychała Joanna , Spychała Marcin
Published: January 2022

Within the EU cohesion policy, better and worse developed regions are subcategorised, taking account of the GDP value per capita. Based on that, areas qualifying for obtaining support from aid programs from the EU budget are established. The purpose of the article is an attempt at specifying the co-dependencies between the EU fund absorption and the changes in the level of the socio-economic development in the regional dimension. The research was conducted at the level of 73 NUTS-3 units in Poland in three stages. At the first one, the level of the development of the subregions in Poland is exhibited, subcategorising the factors of that development: human capital, material capital, natural environment as well as entrepreneurship and innovativeness. At the second stage, variation in the EU fund absorption in the researched units is presented. At the third stage, interdependencies between the extent of the absorption and the changes in the level of development within the arrangement of the factors of that development are taken up.
Fiscal transparency in recovery from the COVID-19 pandemic crisis
Authors: Małecka-Ziembińska Edyta
Published: January 2022

The aim of the article is to present the impact of unprecedented fiscal meas- ures taken in the context of the COVID-19 pandemic on fiscal transparency and to identify the role and importance of fiscal transparency in the process of recovering from the crisis. The conducted analysis proved that in the vast majority of countries around the world, the condition of public finances, measured by the deficit and pub- lic debt, has declined significantly as a result of measures taken to reduce the effects of the COVID-19 pandemic. These activities and strategies contribute to the lack of fiscal transparency. Meanwhile, fiscal transparency is an ally in recovering from the crisis. Strong fiscal frameworks (including numerical rules which promote fiscal pru- dence), backed by clear communication of policy priorities and fiscal transparency can meaningfully contribute to strengthening the credibility of public finances and reduce borrowing costs. These conclusions may be particularly important for emerging mar- ket economies and low-income developing countries, which find it more difficult and more expensive to obtain return sources of financing public investments.
ОБРАЗОВАНИЕ ТРЕЩИН ГИДРАВЛИЧЕСКОГО РАЗРЫВА ПЛАСТА В КАРБОНАТНЫХ СЛОЖНОПОСТРОЕННЫХ КОЛЛЕКТОРАХ С ЕСТЕСТВЕННОЙ ТРЕЩИНОВАТОСТЬЮ

Филиппов, Ли Ювэй // Известия Томского политехнического университета. Инжиниринг георесурсов. – 2022. – Т. 333. – № 1. – С. 85-94

Актуальность исследования обусловлена тем, что наличие естественной трещиноватости в карбонатных сложнопостроенных коллекторах является основным фактором, который влияет на форму и распространение сети трещин гидравлического разрыва пласта. В таких случаях, когда трещина гидравлического разрыва пласта сталкивается с естественной трещиноватостью, может иметь место различный характер их взаимодействия, например смещение, пересечение и т. п. Следовательно, проведение гидравлического разрыва пласта в сложнопостроенных карбонатных коллекторах, характеризующихся наличием естественной трещиноватости, может привести к образованию не симметричной трещины в ее классическом понимании, а их сложной сети. На основании полевых наблюдений (микросейсмический мониторинг и исследование пустотного пространства горных пород) установлена разная степень сложности трещин гидравлического разрыва пласта: от простой относительно плоской единичной трещины до достаточно сложной сети трещин. Цель: оценка образования сложных сетей трещин гидравлического разрыва пласта в карбонатных коллекторах с естественной трещиноватостью. Объект: сложнопостроенная карбонатная залежь с системой естественных трещин. Методы: анализ промысловых, технологических, гидродинамических данных и результатов микросейсмического мониторинга в процессе проведения гидравлического разрыва пласта. Результаты. Установлено, что проведение гидравлического разрыва в сложнопостроенных карбонатных коллекторах зачастую не приводит к образованию трещины в классическом ее понимании – два крыла, распространяющиеся симметрично от ствола скважины, что подтверждено результатами анализа графиков кривых восстановления давления в диагностических билогарифмических координатах. Трещины гидравлического разрыва пласта могут распространяться в пласт непосредственно от скважин – объектов воздействия (классическое представление), либо через существующую сеть естественных трещин, расположенных в зоне дренирования. Для вовлечения в процесс фильтрации значительного количества естественных трещин и других видов пустотности в процессе проведения гидравлического разрыва пласта жидкость разрыва целесообразно закачивать при низких скоростях. Контроль за развитием трещин гидроразрыва должен основываться на достоверной информации о естественной трещиноватости коллектора до проведения мероприятия, а регулирование – посредством мониторинга динамики давления и скорости закачки, что подтверждает результаты исследований.

Актуальность исследования обусловлена необходимостью изучения вторичного загрязнения водной среды металлами в весенне-летнее время, когда активизируются разнообразные биогеохимические процессы, влияющие на изменение физико-химического состояния поверхностного слоя донных отложений. Цель: изучение закономерностей образования и миграции растворимых форм металлов в системе «донные отложения – поровая вода – придонная вода» в весенне-летнее время в прибрежной зоне восточной части Финского залива. Объекты: пробы поверхностного слоя донных отложений, поровой и придонной воды пяти станций прибрежной зоны восточной части Финского залива. Методы: потенциометрический метод определения pH и Eh в донных отложениях и придонной воде. Валовые концентрации Fe, Zn, Cd, Pb, Cu в донных отложениях определяли методом масс-спектрометрии с индуктивно-связанной плазмой (ICP-MS). Концентрации растворенных форм металлов (Fe, Cu, Cd, Zn, Pb) в поровой, придонной водах определяли методом масс-спектрометрии с индуктивно-связанной плазмой на приборе «Agilent 7700x» (фирма «Agilent Technologies»). Результаты. Установлены закономерности образования и миграции растворимых форм металлов на границе «донные отложения – вода» в прибрежной зоне восточной части Финского залива в зависимости от изменений температуры, кислородного режима в придонных водах и окислительно-восстановительных процессов, формирующихся в поверхностном слое донных отложений. Показано, что в конце весеннего сезона в донных отложениях восточной части Финского залива устанавливаются восстановительные условия, способствующие восстановлению гидроксидов железа, накопившихся на дне. В результате возникает поток растворенных форм Fe, Cu, Zn, Cd, Pb в поровые и придонные слои воды. В июле загрязненность поровых и придонных вод всеми изученными металлами снижается.

Актуальность исследования обусловлена повышением требований к эксплуатационным свойствам гибких кабелей, применяемых в системах питания и управления горношахтного электрооборудования. Основным направлением, обеспечивающим улучшение свойств, является применение новых электроизоляционных материалов. На сегодняшний день шахтные кабели изготавливаются преимущественно с изоляцией из резины. Перспективным решением в плане совершенствования конструкций гибких шахтных кабелей является применение этиленпропиленовой резины, обладающей более высокой нагревостойкостью по сравнению с применяемыми резинами на основе хлоропренового и бутилкаучука. Повышение допустимой температуры нагрева токопроводящих жил позволит повысить передаваемую мощность, высокие значения тока термической устойчивости при коротком замыкании с обеспечением требуемой гибкости. Практическое применение кабелей нового типа в системах горношахтного электрооборудования невозможно без экспериментального подтверждения ресурсных характеристик. Отсутствие в технической литературе рекомендаций по проведению подобных испытаний определяет необходимость исследований, позволяющих прогнозировать срок службы гибких кабелей с учетом изменения физико-механических свойств этиленпропиленовой резины. Цель: разработать методику и определить срок службы гибких кабельных изделий с изоляцией из этиленпропиленовой резины для систем питания и управления горношахтного электрооборудования. Объект: гибкий шахтный кабель, изоляция, этиленпропиленовая резина, физико-механические свойства, энергия активации, срок службы. Методы: экспериментальные методы оценки физико-механических свойств и теплостойкости полимерных материалов; математические методы решения нелинейных систем уравнений и статистический анализ результатов испытаний. Результаты. Разработана методика определения срока службы кабелей с изоляцией из этиленпропиленовой резины, основанная на методе прогнозирования изменения физико-механических свойств с учетом энергии активации Ea процессов термической деструкции. Определен срок службы гибких шахтных кабелей с учетом температуры.

Authors: Biswas Sabarni , Paul Alivia , Biswas Asok K.
Published: January 2022

Background: Salinity is a major threat that impairs legume growth and development worldwide. Therefore, present study was aimed to determine the potential of seed halopriming in relieving NaCl-induced disturbances on nitrogen metabolism of seedlings of six legume crops viz., Lens culinaris, Cajanus cajan, Cicer arietinum, Lathyrus sativus, Vigna radiata and Vigna mungo that were detected to have differential sensitivity to NaCl. Methods: Nonprimed and haloprimed seeds were grown hydroponically under varying NaCl doses for three weeks. Harvested samples were utilised to characterize the toxic effects of NaCl on nitrogen metabolism of nonprimed and haloprimed seedlings. Results: Nonprimed seedlings exhibited reduced nitrate uptake by virtue of which other assimilatory processes of nitrogen fixation were adversely affected. Haloprimed seedlings experienced lesser toxicity under NaCl stress due to elevated activities of nitrate assimilatory enzymes on account of improved nitrate uptake from solution. Lesser ammonium accumulation and lower glutamate dehydrogenase activity implied lesser cytotoxicity in primed seedlings. Based on the trends obtained from tested parameters, nitrogen metabolism was maximally affected in Lens and Cajanus followed by Cicer and Lathyrus. Vigna radiata and Vigna mungo were least affected and therefore may be suggested for cultivation in saline prone agricultural fields after seed halopriming.

Background: A field experiment was conducted at the Instructional Farm of Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur during Rabi 2016-17 and 2017-18 to study the weed flora, growth, yield and economics of fenugreek. The experiment was laid out in split plot design with three replications having Fenugreek variety RMT-305 (25 kg ha-1) and RDF of 40 kg N and 40 kg P2O5 ha-1 (basal dose through urea and DAP). Methods: Herbicide applied as pre-emergence (PE) at one day after sowing, while post-emergence (PoE) application at 2-4 leaf stage of weeds (21 DAS) with knapsack sprayer having flat fan nozzle using 500 liters of water ha-1. Result: The pooled results revealed that pre-emergence application of oxadiargyl 100 g/ha fb hoeing at 40 DAS recorded significantly higher weed control efficiency (82.3%), plant height (59.83 cm), number of branches (6.09), number of pods (44.86), number of seeds/pod (17.33), seed weight (9.05 g/plant) of fenugreek. Also, significantly maximum seed yield (2.82 t/ha), haulm yield (6.70 t/ha) and harvest index (29.7%) of fenugreek was recorded under oxadiargyl 100 g/ha PE fb hoeing at 40 DAS which was at par with weed free treatment. Significantly higher net returns (98158 `/ha) and B C ratio (2.63) was obtained with application of oxadiargyl 100 g/ha Pre-Emergence (PE) fb hoeing at 40 DAS. Residual effect of herbicides used in fenugreek did not showed any phytotoxic effect on succeeding summer fodder maize in terms of visual phytotoxicity rating at various growth stages of maize, weed flora, dry matter of weeds as well as crop at 30 DAS and green fodder yield of summer fodder maize.

The paper considers the gradual development of the processing capacity of the Busan transport hub (Republic of Korea) with an increase in the number of incoming transport and containers, taking into account the optimal financial investments and the effectiveness of the measures under consideration in a certain time period. The paper presents four stages - organizational, technological, technical, infrastructural, if after the implementation of these stages the transshipment point cannot cope with the increasing container flow, then the fourth stage should be considered - the construction of a new transport hub. The factors that make up the processing capacity of the transport hub were determined, the factors were classified by interacting modes of transport. The factors have different financial costs and influence on the strengthening of the processing capacity of the elements of the transport node, the paper presents a mathematical description of the effect of the implementation of the factor at a certain stage of the development of the transport node.

Published: January 2022

Fine adjustment of the fuel injection system makes it possible to achieve the identity of working processes in all cylinders of a diesel engine. The paper presents the results of experimental verification of the method developed and published earlier by the authors, which uses only the chart of net heat release. The method allows instability of the engine load mode during engine tests and does not require measurement of the pressure signal in all engine cylinders simultaneously. In addition to the tuning tasks, the paper shows the possibility of detecting injector malfunctions leading to poor fuel atomization.
Malignant hyperthermia

Published: January 2022

Malignant hyperthermia manifests as hypermetabolism of striated voluntary muscle. Generally, this condition occurs during general anesthesia when inhalational anesthetics and succinylcholine are used. During the malignant hyperthermia attack, the oxygen consumption increases, lactate accumulates, the production of CO2 grows and excessive heat is generated. The crisis of malignant hyperthermia is a dangerous and potentially terminal complication of general anesthesia that requires rapid resolution in the shortest possible time. The only drug that can stop the acute state of malignant hyperthermia – dantrolen, is currently prohibited for import in Russia and is not legalized. Treatment of malignant hyperthermia is extremely difficult for all anesthesiologists in Russia and a great danger for patients with this condition.
La confluencia entre raperos chilenos y sellos discográficos multinacionales en la década de 1990
Authors: Rodríguez Vega Nelson
Published: January 2022

El artículo estudia la confluencia entre raperos chilenos y sellos discográficos multinacionales (majors) en la década de 1990. Este período se distingue por una serie de cambios en el despliegue del hip-hop en Chile. La injerencia de las majors fue importante porque consolidó una red de soporte integrada también por otros agentes, entre cuyos resultados estuvo que el rap/hip-hop alcanzó cierta ratificación social, artística, cultural y de productividad. Por otro lado, esta operación es comúnmente desatendida a nivel académico. Se infiere que el resultado referido no armoniza, de alguna forma, con la habitual representación contrahegemónica del hip-hop, lo cual ha significado un vacío bibliográfico. En última instancia, este artículo intenta demostrar que la vinculación con la industria cultural/mercado no se traduce necesariamente en la pérdida de la función social de la música y que, además, existirían formas alternativas de ejercer una resistencia cultural no ceñidas a efectuar irremediablemente una crítica social en letras de canciones, o a la toma de posición política explícita, por parte de los músicos populares.
O (im)provável encontro entre o Mulato Calado e o Delegado Chico Palha
Authors: Junqueira Humberto
Published: January 2022

A pesquisa em música vem se desenvolvendo e ganhando novas abordagens a partir de contribuições advindas de diversos campos do conhecimento. A perspectiva interdisciplinar, portanto, tem se constituído como alternativa promissora diante de questões que emergem especialmente a partir da música popular, área privilegiada para a investigação de pontos estruturantes de nossa sociedade. No presente trabalho, além de ressaltar as concepções que forjaram o conjunto de disciplinas que se dedicam ao estudo da música (tomada, nesse sentido, como uma instância abstrata), analiso também dois sambas compostos na primeira metade do século XX. O objetivo dessa análise é justamente revelar a dimensão social e “concreta” da música, apontando para as tensões, conflitos e contradições presentes na cultura brasileira. O encontro entre o “Mulato calado” e o “Delegado Chico Palha”, entre a polícia e o matador, entre um homem violento (“sem coração”) e o defensor de sua companheira, permite não apenas lançar um olhar sobre alguns aspectos estruturantes do quadro sociocultural brasileiro, mas também propicia a reflexão sobre novas formas de lançar esse olhar através da pesquisa em música.
