Highlights

The article presents a unique clinical case of correction of hypoplastic left heart syndrome with Norwood procedure using a “KemAngioprosthesis” vascular xenograft as a Sano shunt.

 

Abstract

We present the first successful clinical case of using the “KemAngioprosthesis” vascular xenograft in the pulmonary position as the Sano shunt in the Norwood procedure for correction of hypoplastic left heart syndrome. A newborn baby (gestation period of 38 weeks) diagnosed with congenital heart disease, and hypoplastic left heart syndrome was admitted to the Research Institute for Complex Issues of Cardiovascular Diseases. The child survived the first stage of the modified Norwood procedure (Sano shunt) using a biological vascular prosthesis. This clinical case showed that using the “KemAngioprosthesis” vascular xenograft in Norwood procedure to modify pulmonary blood flow by creating an anastomosis between the right ventricle and bifurcation of the pulmonary artery is effective and safe in the short-term period.

Highlights

Stabilization of bovine pericardial tissue by ethylene glycol diglycidyl ether does not remove the N-glycolylneuraminic acid contained in its structure, which is one of the most immunoreactive glycan xenoantigens;

N-glycolylneuraminic acid can potentially cause early immune rejection of epoxy-treated bioprosthetic heart valves.

 

Aim. To assess the presence of N-glycolylneuraminic acid (Neu5Gc) in an intact bovine pericardial tissue stabilized by ethylene glycol diglycidyl ether and in the leaflets of epoxy-treated bioprosthetic heart valves (BHV) explanted due to dysfunction.

Methods. By means of immunochemistry (using anti-Neu5Gc antibodies), we studied the fragments of 5 samples of intact epoxy-treated bovine pericardium commonly used in cardiac surgery. Similarly, we examined the fragments of the leaflets of 8 epoxy-treated BHVs that lasted for different time periods (1 day to 68 months) and excised during reoperation. The native bovine pericardium and the leaflets of 3 human aortic valves (AV) removed during reoperation in patients with aortic stenosis were used as positive and negative controls, respectively.

Results. Positive reaction for Neu5Gc was observed in intact epoxy-treated xenopericardium and BHVs excised 1, 2, 20 and 42 days after implantation. The tissue of BHV that had lasted 30 months was characterized by the faint presence of Neu5Gc. In the leaflets of AV and in BHVs, explanted after 34, 63 and 68 months, Neu5Gc was not detected. 

Conclusion. Stabilization of xenobiomaterial with ethylene glycol diglycidyl ether does not remove the Neu5Gc. This saccharide remains in the biological tissue of epoxy-treated BHV for about 2.5 years after implantation.

Highlights

Higher rates of COVID-19 morbidity and mortality compared to Russia as a whole were noted in Moscow during the COVID-19 pandemic and after it (2020-2021). We have reached the conclusion that it is necessary to develop regional prevention and rehabilitation approaches for COVID patients.

 

Aim. To analyze health and demographic indicators of Moscow, Russia and its constituent entities in the context of the COVID-19 pandemic to develop regional prevention, management and rehabilitation programs for COVID patients.

Methods. The study incorporated statistical, analytical, and observational methods. The data of the Federal State Statistics Service, and reports of the Central Research Institute of Healthcare of the Ministry of Health of Russia for 2012–2022 were used for the analysis.

Results. General morbidity of the population in Moscow (2021) amounted to 148 906.0 per 100 000 population. The highest rates were noted in the following classes of diseases: diseases of the respiratory system, circulatory system, diseases of the musculoskeletal and connective tissue, genitourinary system, etc. In the Russian Federation, the overall incidence rate in 2021 was 167 713.8‰00, which is 11.6 % higher compared to Moscow. In 2019 (before the COVID-19 pandemic) the frequency of primary morbidity in Moscow was 65 818.1‰00, in 2020 the frequency decreased to 63 204.4‰00, and in 2021 it increased to 71 523.9‰00, which is 8.7% higher than in 2019. Between 2019 and 2021, there was an increase in primary morbidity rates in the following classes of diseases in Moscow: mental and behavioral disorders by 12.1%, diseases of the blood, hematopoietic organs and disorders involving the immune mechanism – by 5.3%, diseases of the nervous system – by 2.1%, etc., which indicates the need for rehabilitation of patients with this pathology. In 2021 the incidence rate of COVID-19 in Moscow increased to 8 976.0‰00, in the Russian Federation the incidence rate was lower – 8 085.7‰00. The difference in indicators between the constituent entities of the Russian Federation is quite high and amounts to 11.8. The pandemic has exacerbated the demographic situation in Russia. Mortality rates (for 2019–2021) increased in the Russian Federation from 12.3‰ to 13.6, and in Moscow the increase was more significant – from 9.5 to 16.7‰. The results of the analysis indicate the need to improve preventive and management programs for COVID patients, even more so in Moscow. In Moscow and Russian Federation as a whole higher rate of general morbidity in children and adolescents compared to total and adult population morbidity over 10 years (2012–2021) points to the importance of prevention and management programs of this population.

Conclusion. The results of the study reaffirm the need to develop regional prevention, management and rehabilitation approaches for COVID patients.

Highlights

ECG signs of metabolic cardiomyopathies in men aged 25–44 years, regardless of age and waist circumference, are directly associated with the serum adipsin concentration and inversely associated with the concentration of glucagon-like peptide 1 in the blood.

ECG signs of metabolic cardiomyopathies in women aged 25–44 years are directly associated with the serum c-peptide concentration and inversely associated with the concentration of glucose-dependent insulinotropic polypeptide 1 in the blood.

 

Abstract

Aim. To study the relationship between electrophysiological signs of metabolic cardiomyopathy (MC) and biomolecules associated with the secretory activity of visceral adipocytes in persons aged 25–44 years residing in Novosibirsk.

Methods. The study included 1 198 subjects. A single-stage survey of a random sample of the 25–44-year-old population of Novosibirsk (49,7% men, 50,3% women) was conducted. During the examination, among other things, a resting 12-lead ECGs was recorded, and later the ECGs were classified according to Minnesota Code categories. Five ECG signs of MC were analysed: 1) ST-segment displaced above baseline (ST-segment elevation); 2) ST-segment displaced below baseline (ST-segment depression); 3) T wave changes; 4) TV1>TV6 patterns and 5) ECG signs of left ventricular hypertrophy. Serum concentrations of biomolecules associated with the secretory activity of visceral adipocytes were determined by multiplex analysis.

Results. The results of multivariate logistic regression analysis showed that the ECG signs of MC in men aged 25–44 years, regardless of age and waist circumference, are directly associated with the serum adipsin concentration (Exp B 1,039, 95% CI 1,002–1,077, p = 0.039) and inversely associated with the concentration of glucagon-like peptide 1 in the blood (Exp B 0.999, 95% CI 0.998–1,000, p = 0.042). ECG signs of MC in women aged 25–44 years are directly associated with the serum peptide concentration (Exp B 1,439, 95% CI 1,082–1,915, p = 0.012) and inversely associated with the concentration of glucose-dependent insulinotropic polypeptide in the blood (Exp B 0.986, 95% CI 0.978–0.995, p = 0.001).

Conclusion. The results obtained reflect the significant influence of these biomolecules associated with the secretory activity of visceral adipocytes on the occurrence of ECG signs of MC in young people aged 25–44 years.

Highlights

Every year more than 4 million deaths are registered from cardiovascular diseases (CVD), which is 46% of all deaths. Over the past 40 years, a downward trend in mortality from CVD has been revealed. However, the COVID-19 pandemic period has changed the statistics of indicators of both total mortality and mortality from CVD.

 

Aim. To analyze the mortality rate (MR) features from CVD in the Kemerovo Region (KR) from 2017 to 2021, in comparison with the Russian Federation (RF) rate.

Materials and Methods. Mortality rates of the adult population of KR and RF for the period 2017–2021 were taken from the official sources. The KR/RF dynamics was approximated by a linear trend using Microsoft Excel 2010.

Results. Over the past 5 years (from 2017 to 2021) the increase in mortality from CVD was 58.2% in the KR and in the RF – 9%. In 2017 the mortality rates in the RF were higher than in the KR and they levelled off by 2018. However, in the period 2019-2021 there was a sharp increase rate in the KR, in comparison with the RF. According to Kemerovo Statistical Office, the mortality rate from CVD in the region in 2021 was 10.8% higher than in 2020. The structure of mortality from CVD in 2021 in the KR had 52.8% of death cases due to coronary heart disease and 32.6% were caused by the cerebrovascular disease. During the COVID-19 pandemic (2019–2021) the first 3 places among the causes of total mortality in the KR were occupied by CVD (46.3% – 49.4% – 49.3%, respectively), neoplasms (17.1% – 15.2% – 13.2%) and external causes of death (9% – 7.7% – 6.5%). In the structure of total mortality cases the COVID-19 share is 2% in 2020 and 6.4% in 2021, respectively, which raised them to the 4th place in 2021.

Conclusion. An increase in mortality rates in the region may indicate both the real causes of death, they can also be associated with the peculiarities the death cases coding and the impact of clinical and organizational technologies as well as the aging of the population. All the data  require further in-depth research.
Mechanism and Kinetics of 2D Transition Metal Carbides (MXenes) Synthesis
Authors:   , Anayee Mark , Gogotsi Yury
Published: October 2023

Two-dimensional (2D) nanomaterials including graphene, hexagonal boron nitride (h-BN), transition metal dichalcogenides (TMDs), and MXenes have attracted much attention because they present a wide range of physicochemical, optoelectronic, and mechanical properties along with various atomic structures and compositions. MXenes represent the largest and rapidly growing family of 2D transition metal carbides and/or nitrides, which exhibit unique combinations of properties, including metallic conductivity, hydrophilic surface chemistry, redox-active surface, and plasmonic behavior that make them attractive as electrodes for pseudocapacitive energy storage to coatings for electromagnetic interference shielding, transparent conducting displays for optoelectronics, conductive yarns for functional textiles, implantable electrodes for medicine, and many other applications. MXenes are typically derived via topochemical etching of atomically thick layers from precursor layered MAX phases using corrosive aqueous etchants. However, the chemical etching process is only somewhat optimized for one composition, and is nonetheless often slow, with low-yield, and results in defects in the materials.
Adaptive Reuse and Its Impact on Workforce Revitalization
Authors:   , Bell Rachael , Stratton-Rayner Joshua M
Published: October 2023

Adaptive reuse of historic industrial buildings is often touted as a driver of modern economic development in urban areas but also impacts workforce revitalization. For post-industrial cities facing economic challenges such as a lower tax base, reduced population sizes, an increase in vacant buildings or lots, a depleted workforce, and limited resources to support that workforce, adaptive reuse is one method used by developers and city officials to bring these distressed cities back to life. This thesis explores how cities implement workforce development and revitalization strategies by changing their built environment, especially the historic industrial built environment. The key components of adaptive reuse examined in this thesis are the economic and financial viability of adaptive reuse projects, the environmental and sustainability challenges and impact, and the social impacts preservation can have on a community. This thesis highlights three projects in different post-industrial cities- Buffalo, NY, Baltimore, MD, and Philadelphia, PA, and how adaptive reuse projects are helping make economic, sustainable, and social improvements in their communities while retaining their historic fabric.
Exploring the Experiences of Foreign-Born Teachers to Ascertain Perceived Factors and Barriers to Passing the Teacher Licensure Exam
Authors:   , Black Veronica Elaine , Grant Kristine
Published: October 2023

Historically, teacher exams have been suspected of racial disparities and cultural bias. The National Council on Teacher Quality (NCTQ) report the first-time passing rate is 48%. While 75% of white applicants score a passing grade, a proficiency gap exists where only 38% of Black/African Americans pass. Foreign-born Black teachers are included in the subgroup of Black teachers despite their ethnic or cultural origins; yet there is limited knowledge about their experiences with the teacher licensure examination. The purpose of this hermeneutical phenomenological qualitative study was to understand the lived experiences of foreign-born teachers-of-color who identify as Black and explore their perceptions of factors and barriers to passing the teacher licensure exam the first time. Ten immigrant teachers-of-color who identify as Black or African American participated in this study. All of the teachers teach in either a regular public school or charter public school. The teachers represent three Caribbean countries and four African countries. Eight of the ten participants passed the teacher licensure exam on the first attempt. The two participants who did not pass on the first attempt attribute their challenges to language differences. Three themes were uncovered during data analysis: (1) Personal Responsibility and Accountability (2) Prior Educational Success and Attainment; and (3) Exam Preparation Strategies. The participants revealed the roles of intersectional factors such as language, immigration status, family, religion and culture with academic success. The participants attributed intrinsic and extrinsic factors such as attitude, finances, and proper preparation to their performance on the teacher licensure exam, factors that align with the tenets of Achievement Goal Theory. This study is significant to understanding the experiences of Black educators on the teacher licensure exam. By isolating the lived experiences of foreign-born Black teachers, this study illuminates a demographic whose experiences are oftentimes overlooked and enables more nuanced responses to improving the pass rate of Black teachers on the teacher licensure exam. Recommendations for practice and future research are included. Key words: foreign-born Black teachers, teacher licensure, proficiency gap, model minority, achievement goal theory

EMPOWERMENT OF THE CREATIVE ECONOMY THROUGH THE DEVELOPMENT OF A CULINARY BUSINESS NETWORK BANJARMASIN TYPICAL BANANA BREAD CAKECommunity empowerment through the development of the creative economy in the era of globalization is very crucial. This economic development is based on creativity, culture and local excellence, and is a new hope in looking at the nation's economic changes in the future. Creative economy development can be carried out in rural communities, for example in Kayuambon Village, which is located around Lembang, West Bandung Regency, where one of its main commodities is bananas. It's just that the processing of these commodities has not been maximized, so it has not provided significant additional income for the community. Based on this, this research aims to educate the public regarding the innovation of various processed foods made from bananas as the main raw material, in particular the development of a culinary business typical of Kalimantan banana bread and a strategy for developing a network of processed businesses so that they can provide additional income for the Kayuambon Community in Lembang District. The method used is action research. The results of this research, namely the development of a culinary business network for Banjarmasin typical banana bread, can improve the welfare of the people of Kayuambon Village, Lembang District.Pemberdayaan masyarakat melalui pengembangan ekonomi kreatif di era globalisasi menjadi sesuatu yang sangat krusial. Pengembangan ekonomi ini bertumpu pada kreatifitas, kebudayaan serta keunggulan lokal yang dimiliki, dan menjadi harapan baru dalam menatap perubahan ekonomi bangsa di masa mendatang. Pengembangan ekonomi kreatif dapat dilakukan pada masyarakat di pedesaan, contohnya Desa Kayuambon yang berada disekitaran Lembang, Kabupaten Bandung Barat dengan salah satu komoditas utamanya adalah pisang. Hanya saja, pengolahan komoditas tersebut belum maksimal, sehingga belum memberi penambahan pendapatan yang signifikan bagi masyarakatnya. Berdasarkan hal tersebut, penelitian ini bertujuan untuk mengedukasi masyarakat terkait inovasi berbagai olahan makanan yang berbahan baku utama pisang, khususnya pengembangan bisnis kuliner roti pisang khas Kalimantan serta strategi pengembangan jejaring bisnis olahan tersebut sehingga dapat memberi tambahan pendapatan bagi Masyarakat Kayuambon Kecamatan Lembang. Metode yang digunakan yaitu action research. Hasil yang didapatkan setelah melaksanakan penelitian, yaitu pengembangan jejaring bisnis kuliner roti pisang khas Banjarmasin, dapat meningkatkan kesejahteraan masyarakat desa Kayuambon Kecamatan Lembang.
Cultura do privilégio: entrave para o desenvolvimento econômico na América Latina
Authors: De Moraes Isaías Albertin
Published: October 2023

O presente artigo tem como objetivo contribuir para o entendimento dos entraves para um projeto de desenvolvimento econômico na América Latina contemporânea. A premissa elencada pela pesquisa é a de que os projetos e as estratégias desenvolvimentistas executados pelos governos vanguardistas nos países da América Latina sofrem de entraves e se tornam truncados em virtude, frequentemente, da cultura do privilégio presente na sociedade latino-americana. O artigo optou em realizar pesquisa de revisão bibliográfica pautada em leitura sintópica. Os resultados obtidos são de que, na América Latina, grande parte da elite dirigente carrega introjetada um desprezo pelo seu próprio povo –visto como "subgente"– e um fascínio e subalternidade perante o colonizador –economias centrais– visto como modelos de humanos e de civilização. Isso faz com que haja uma cultura do privilégio responsável por um horror social e fator relevante pelo entrave ao desenvolvimento econômico na região.
O processo de internacionalização das empreiteiras brasileiras durante a ditadura civil-militar (1964-1988): características, padrões e tendências
Authors: Pedreira Campos Pedro Henrique
Published: October 2023

O artigo aborda o processo de internacionalização das empreiteiras brasileiras durante o regime ditatorial inaugurado em 1964. Tratamos dos contratos firmados pelas construtoras brasileiras no exterior desde a década de 1960, notando características, padrões e tendências do fenômeno. Para desenvolver a análise, utilizamos fontes das empresas, memórias e periódicos divulgados no período, acessando o método quantitativo para o trabalho com os dados e os ensinamentos da economia política internacional. Concluímos, por um lado, que o movimento ganhou fôlego por conta da emergência de um mercado global de obras de infraestrutura, principalmente após o choque internacional capitalista de 1973 e, por outro, que a tendência foi viabilizada por uma ação deliberada do Estado brasileiro de promover a acumulação de capital, a formação de grandes grupos econômicos, além de proteger e projetar suas empresas no exterior a partir da década de 1970.

Published: October 2023

This paper studies tax evasion in the form of under-reported wages in Ecuador using microdata from a combination of electronic billing and personal income tax returns filed in 2017. Bringing together this novel combination of data, the study applies the standard method Pissarides and Weber (1989) used to estimate the under-reporting of income by comparing public- and private-sector employees. The results demonstrate empirically that under-reporting of income in private-sector employees is between 7 and 9 percent of their income, which translates to an estimated 3 percent of unregistered GDP. The under-reporting has important implications for social security, reducing these contributions by about 10 percent. Beyond the overall picture of under-reporting, the study detects substantial heterogeneities concerning firm size, concluding that the gap size is negatively correlated with the number of employees at the firm, which is consistent with different risks and administrative costs of envelope wages in small versus large firms.

Contesting “growth” and “sustainability” in Indonesia’s capital city relocation: a corpus ecolinguistic study
Authors:   Gadjah Mada University, Suhandano Suhandano , Isti’anah Arina ,   Sanata Dharma University, Febrina Ria ,   Andalas University
Published: October 2023

The global environmental crisis has triggered academic discussions on how infrastructure discourse often eliminates the environment as a part of the ecosystem. One noticeable contested issue is Indonesia’s capital city relocation from Jakarta to Penajam Paser Utara, Borneo Island. Considering the island’s biodiversity hotspot, the capital city relocation has invited debates about environmental impacts. Despite the criticism and scepticism of the government’s ambitious project, the Indonesian House of Representatives passed the relocation law, followed by the president’s capital city development regulations. Some research has discussed the new capital city (NCC) discourse, but the analysis from a corpus ecolinguistic perspective is absent. It is hypothesised that the lexemes “growth” and “sustainability” in the NCC legal documents represent the government’s intention to communicate the relocation intention and legitimise the plan. Therefore, this paper investigates the employment of lexemes “growth” and “sustainability” in the NCC legal documents using Sketch Engine, an online corpus tool developed by Adam Kilgarriff. Additionally, we also observed the nominalisation and transitivity of the concordances where the lexemes were used in the documents. The analysis revealed that “growth” and “sustainability” are inextricably linked to project NCC as a tool to accelerate and catalyse regional and national economic growth. Ecologically, the NCC documents promote an eco-ambivalent discourse since the sustainability objective excludes the environment. Instead, industrial sustainability is the primary goal in the capital city relocation. The country’s welfare measured by its economic success is salient in the discourse, whereas humans’ responsibility towards the deforestation impacts of relocation is lacking. This research was funded by the Final Project Recognition Grant Universitas Gadjah Mada, Number 5075/UN1.P.II/Dit-Lit/PT.01.01/2023. We are also indebted to the editors of Research Result.

Violencia, Estado de derecho y políticas punitivas en América Central
Authors: De la Torre Verónica , Alvarez Alberto Martín
Published: October 2023

Este artículo plantea que los elevados niveles de violencia y criminalidad en el Triángulo Norte de América Central –Guatemala, El Salvador y Honduras–, en presencia de aparatos estatales incapaces de hacer valer el Estado de derecho, está produciendo una ansiedad creciente en la población y concitando el apoyo de ésta para implementar medidas autoritarias que combatan el crimen. La respuesta de los gobiernos de esta región ante el auge de la criminalidad y la demanda ciudadana de seguridad han sido las políticas de "mano dura" contra el crimen y el recurso del "populismo punitivo" como estrategia para capitalizar electoralmente la profunda preocupación por la inseguridad.AbstractThis article suggests that high levels of violence and crime in the so called North Triangle of Central America (Guatemala, El Salvador and Honduras), together with the incapacity of the state of enforcing the rule of law, are causing growing anxiety among the population and are attracting the support of the community to implement authoritarian measures to fight crime. The response of the governments of the region in the face of the rise of crime and public demand for security has been the policies of "iron fist", and the use of "populist punitiveness" as a strategy to gain the backing of an electorate deeply concerned by insecurity.
Las mujeres que vuelan: género y cambio cultural en Cuetzalan
Authors: Rodríguez Blanco Eugenia
Published: October 2023

El presente artículo propone un análisis feminista sobre las dinámicas del cambio cultural en con textos indígenas. Procuramos documentar el proceso seguido por los cambios relativos a la superación de la exclusión o marginación de las mujeres, y analizar los factores que los causaron. En este estudio buscamos datos que puedan probar si tales cambios son consecuencia de una transformación en las relaciones de género —y de un aumento del empoderamiento de las mujeres—, o si son resultado de otros factores e intereses que tienen como efecto secundario una reducción de la marginación femenina. El caso que presentamos aquí es el de la participación de mujeres en la danza de los voladores, un fenómeno reciente que sugiere un cambio cultural vinculado al género.AbstractThis article puts forward a feminist analysis of the dynamics of cultural change in indigenous contexts. We intend to document the processes of cultural change that are concomitant to overcoming exclusion or marginalization of women, and to analyze the factors that cause such transformations. In this study we look for signs that can prove whether these changes are a consequence of a transformation in the gender relations — and an increase in the empowerment of women—or if they are the result of other factors and interests which have the secondary effect of reducing the marginalization of women. The specific case presented here is the participation of women in the "danza de los voladores", a recent phenomenon that suggests a cultural change in relation to gender.

Authors: Maceira Verónica
Published: October 2023

Luego de las profundas transformaciones en las condiciones de estructuración social y política de las clases subalternas argentinas en los años noventa, hacia 2003, con la reactivación económica, las fracciones más organizadas de la clase obrera comienzan a recuperar protagonismo. En este artículo se indaga algunos aspectos de la construcción de este actor colectivo, esto es: las representaciones y orientaciones de delegados y obreros sindicalizados de base con respecto a la organización sindical y la acción colectiva. El estudio se basa en un conjunto de entrevistas en profundidad realizadas a trabajadores varones sindicalizados de las industrias metalúrgicas, textil y de la construcción en el área metropolitana de Buenos Aires. Se describen las tendencias dominantes, las diferencias intergeneracionales y la relación entre la construcción de una conciencia sindical y la identidad peronista.AbstractAfter the transformations in social and political conditions of Argentine workers in the '90, the organized fractions of the working class have recovered their prominence since 2003, because of the economic reactivation. In this study, we explore some aspects of the subjective reconstruction of this collective actor: representations and attitudes regarding unions and collective action. Research is based on a group of in-depth interviews with unionized workers who work either in the manufacture industry or in the construction sector, in the metropolitan area of Buenos Aires. We describe the main tendencies, the profiles of different generations and the relations between trade-unionist consciousness and peronist identity.
Ley de Caducidad en Uruguay y esencia ético-política de la izquierda
Authors: Buriano Ana
Published: October 2023

En este artículo se comparan los comportamientos partidarios y ciudadanos en los referéndum y plebiscito respectivos de 1989 y 2009 en Uruguay, relativos a la derogación o anulación de artículos de la ley de amnistía, así como el inconcluso epílogo de este trámite. Ello permitirá apreciar un cambio en la fuerza-eje impulsora de las iniciativas ciudadanas en la materia. Mientras en 1989 el Frente Amplio (FA) asumió y promovió el referéndum derogatorio, en 2009 las organizaciones sociales ganaron la centralidad de la escena. En ese último año, la negativa y posterior apoyo a la campaña plebiscitaria, con prescindencia práctica de esta coalición, cuestionó el ámbito de gestión de las demandas relativas a los derechos humanos y la esencia ético-doctrinal de la izquierda partidaria. Aunque en 2010 el FA intentó retomar el liderazgo, fue golpeado por una polémica interna que derivó en desacatos frente al debate legislativo para neutralizar los efectos de la ley. De la resolución de esta brecha dependerá la configuración cívica, identitaria y quizá político-partidaria del Uruguay del siglo XXI.AbstractThis paper compares parties and citizen behavior in the referendum and plebiscite of 1989 and 2009 in Uruguay, concerning the derogation or repeal of articles of the amnesty law, as well as the unfinished epilogue of this process. This will allow us to observe a change in the axis-force that drives citizens' initiatives in the matter. While in 1989 the Frente Amplio (FA) assumed and promoted the derogatory referendum, in 2009 the social organizations won the centrality of the scene. In that last year the negative position and subsequent support for the plebiscite campaign by the partisan left. Its virtual absence from the coalition generates doubts about the management of the demands concerning human rights and the ethical-doctrinal nature of the partisan left. Although in 2010 the FA tried to resume leadership, it was weakened by an internal dispute that resulted in contempt towards the legislative debate to neutralize the effects of the act. The civic, identity and perhaps political configuration of the XXI century Uruguay will depend on the resolution of this gap.

Authors: Fernández Víctor Ramiro , García Puente Maria Jimena
Published: October 2023

Luego de las experiencias de ajuste estructural y de políticas neoliberales, el Estado retornó como un actor relevante a las agendas del desarrollo en América Latina. Con la finalidad de identificar los desafíos que debe afrontar en la definición e implementación de estrategias orientadas al desarrollo en el contexto actual, en este artículo se exponen aportes teóricos para analizar al Estado, y se plantean lineamientos para pensar sobre cuáles son los retos que ha de enfrentar hoy en día como protagonista del desarrollo. El enfoque analítico que se propone emerge del establecimiento de diálogos entre dos perspectivas teóricas que han permanecido inconexas, para analizar la intervención estatal en el marco de la transformación organizacional, espacial y funcional del Estado, junto con las cualidades y calidades tanto de sus estructuras como de sus vínculos con los actores de la sociedad civil.AbstractThe renewed importance of the nation state in promoting economic development in Latin America and the organizational, spatial and functional transformations it has undergone raise questions regarding the requirements and conditions necessary for the state to fulfill the role demanded by present historical conditions. In this article we discuss two theoretical perspectives on the state that have up to day been loosely connected and suggest several guidelines conducive to the definition and implementation of public policies that promote endogenous, equitable and balanced development in the region.

This article aims to enhance the vitality and cultural heritage of traditional Chinese martial arts and discusses the protection and development of traditional Chinese martial arts from the perspective of folklore intangible cultural heritage (ICH) protection. Studies indicate that to continue the development of traditional Chinese martial arts from generation to generation, it must adapt to the laws of current social and cultural development. With the goal of improving the vitality of traditional martial arts culture, on the basis of adhering to the inheritance of the core skills of traditional martial arts, it advocates an innovative development mode that keeps pace with the times. Its fundamental purpose is to enable the sustainable and healthy development of traditional martial arts.
Modern nematode-resistant varieties of potatoes in the conditions of the North
Authors: Zhigadlo T. E.
Published: October 2023

Golden potato nematole (Globodera rostochiensis Woll.) is a phytoparasite, a microscopic worm that causes potato globoderosis. As a result, the yield is sharply reduced, small tubers are formed, and then the complete death of plants. The damage caused by the golden potato nematode manifests itself when the soil is infected with larvae in the amount of 1 thousand pieces or more in 100 cm3. The decrease in yield in areas of severe infection can reach from 70 to 90%. Early potato varieties are most affected. The best way to protect potato varieties from globoderosis is to use in the production of varieties resistant to golden potato nematode. The aim of the research was to study nematode-resistant potato varieties in the Murmansk region.

Methods. In 2016-2020, 49 potato varieties resistant to globoderosis were studied on the experimental field of the Polar Experimental Station of VIR according to the main biological and economically valuable characteristics. The size of the plot was 0,05 ha, the area of plant nutrition was 70x30 cm. Planting of varieties was carried out in early June. The samples were planted in the field in a row of 10 plants of each variety. Every 10 samples, the Khibinskiy ranniy variety was located. All accounts are performed according to the VIR methodology.

Results. Phenological observations have shown varieties with short periods of passage of phenological phases: Diamond, Grand, Pershatsvet, Khibinskiy ranniy, Roeslau. Berry formation was of the Labadia variety. The yield on the 60th day from planting was 531.7-741.7 g / bush (the maximum yield of the Madeleine variety). On the 90th day from planting, the yield of the varieties was in the range of 747,5-1153,0 g/bush (the maximum for the Eurasia variety). Starch content varied from 8,3% (Arrow grade) up to 20,4% (Albatros). According to disease resistance, the varieties Grand, Gusar, Eurasia, Harmony, Colorit, Rasinka, Albatros, Angela, Courage are distinguished.

Conclusion. Samples of the world potato collection have been studied; sources of valuable traits that can be used in breeding work to create new varieties suitable for cultivation in the Far North have been identified.

Timeliness.The prerequisites for the cultivation of bog cranberry (Vaccinium oxycoccosL.) in industrial plantations have led to an increased demand for high quality planting material obtained by clonal micropropagation (in vitro). Studies have been carried out on the ofex vitrogrowing completion of cranberry plants using different mineral fertilizers and types of light under greenhouse conditions.

Methods.Ex vitroplants of a selected form of cranberry (Vaccinium oxycoccosL.) obtained using the clonal micropropagation technique were the objects of research. Experimental adapted cranberry plants were planted in 0.5 L containers in 'Veltorf' peat substrate with an acidity of at least pH 3.5-4.0, to which mineral fertilizers were added according to the variants: APAVIVA N15P15K15(S10) 0.08 and 0.16 g/L, Sulfoammophos N16P20(S12) 0.072 and 0.144 g/L, N12P52 0.1 and 0.2 g/L, control without fertilizer. The plants were placed under different types of light: under LED phytolamps (UnionPowerStar – 40W-T) with a photoperiod of 16 hours and under natural light (without the use of additional lighting) under greenhouse conditions.

Results. It was found that during of theex vitrogrowing completion of bog cranberry (Vaccinium oxycoccosL.) plants in containers, the advantage of LED phytolamps was revealed, when using them in all experimental variants on the 42nd day of growing the morphometric indicators of plant development were almost 2 times higher than in plants grown under natural light. The type of mineral fertilizers and type light significantly influenced the total length of shoots (82.9±13.74- 107.4±35.95 cm vs. 58.6±20.92 cm in control) and leaf surface area (41.1±6.46-54.1±4.67 cm2 vs. 22.9±9.63 cm2 ).

Conclusion.The results we obtained contributed to a better representation of theex vitrogrowing conditions of bog cranberry (Vaccinium oxycoccosL.) plants using different types of lighting (phyto-lighting with a 16-hour photoperiod and natural light – without adding additional light) and the selection of optimal doses of mineral nutrition. The best, under LED lighting, were N16P20(S12) at a concentration of 0.072 g/L and N15P15K15(S10) at a concentration of 0.16 g/L.
