Authors: Casamichana David , Barba Eider , Yuzo Nakamura Fábio , Agirrezabalaga Oier , Castellano Julen
Published: June 2024

The aim of the present study was to compare the external load (EL) of the football pre-match warm-up (WU) in absolute terms and as a percentage (%) of the individual match demands. A total of 96 football players from different age categories participated in the study: professional (PRO, n=26), reserve (RES, n=22), under-21 (U21, n=28) and U18 (n=20) teams. Eleven EL variables were obtained through global positioning system devices. The results show that there are differences among teams in total duration, total distance, number of accelerations and decelerations, acceleration load, distance covered at different speed ranges and the maximum velocity, both expressed absolutely and relative to the match demands. The EL of the WU represents a variable percentage depending on a particular variable with respect to the match, ranging from ≈5% for high-speed running or very high-speed running to ≈20% for acceleration-load. The conclusions were: 1) the WU load represents an important part of the EL on players in soccer matches, and 2) the PRO team presented a lower EL in most of the variables, being consistent in both absolute and relative terms to the match demand. The strength and conditioning coaches must be cautious not to cause fatigue in the players while guaranteeing an adequate set-up to dispute the match.
STATE-DEPENDENCY IN THE NEXUS BETWEEN DIGITAL FINANCIAL INCLUSION AND ECONOMIC GROWTH IN SUB-SAHARAN AFRICA
Authors: Jimoh Lukman , David Oladipo Olalekan
Published: June 2024

Objective: The objective of this study is to investigate state-dependency in the nexus between digital financial inclusion and economic growth in sub-Saharan Africa, with the aim of examining the impact of adopting digital financial technology to reduce financial exclusion and contribute to economic growth.
 
Theoretical Framework: The paper extends the work of Sarma (2008) and Khera et al. (2021), by creating a new financial inclusion index that captures both traditional and digital financial inclusion.
 
Method: The methodology adopted for this research comprises the principal component analysis (PCA) to identify signals in financial inclusion indicators, thereafter financial inclusion indexes for digital and traditional financial services were constructed. The panel quantile regression methodology was employed to analyse the impact of shocks and determine state dependency in the nexus, respectively. Data collection was carried out through secondary sources.
 
Results and Discussion: The result confirms a positive relationship between digital financial inclusion and economic growth with the greatest impact in countries with lower real GDP, confirming state dependency.
 
Research Implications: The findings suggest that policymakers should focus on promoting digital financial inclusion, particularly in countries with low to intermediate levels of income.
 
Originality/Value: This study contributes to the literature by broadening the definition of digital financial inclusion beyond what is currently found in the literature to include vital financial inclusion dimensions such as access to financial services. The relevance and value of this research are further evidenced by the consideration of state-dependency in the relationship between financial inclusion and growth.

Brain homeostasis requires the maintenance of barriers between the brain and the periphery, which are provided by brain microvessels in the blood-brain barrier and epithelial cells in the choroid plexus. Circumventricular complex (CVC) – structures located around the third and fourth ventricles, lining the cavity of the third ventricle (neurohypophysis, vascular organ of the end plate, epiphysis, subvault and subcommissural organs) and the fourth ventricle (posterior region), different from other structures of the brain due to the maximum vascularization and the absence of a typical blood-brain barrier. The subcommissural organ and the area postrema are located at the confluence between the ventricles, while the neurohypophysis, the vascular organ of the terminal plate, and the pineal gland line the ventricular depressions. All structures of the central nervous system are divided into sensory and secretory. Vessels in the CVC branch into a network of fenestrated capillaries with loosely connected astrocytic ends, which allows them to be considered as gates» to the brain; substances are transported by blood and freely leave the capillary lumen. Neurons and glial cells of the CVC form a unique symbiosis of receptors and ion channels, receiving chemical signals from the bloodstream. CVCs are described as the «windows of the brain» that form the blood-CSF barrier on the ventricular wall, which is composed of tanycyte-like cells that line the ventricular ependyma. Astrocytes and tanycytes form a dense barrier in the distal part of the CVC, preventing the free diffusion of the molecules obtained. from the blood to the neighboring areas of the brain. The barrier in front of the fenestrated vessels of the CVC may limit molecules carried by the blood through these «windows of the brain» and prevent their diffusion into the cerebrospinal fluid. In the central nervous system, connections between the central nervous system and peripheral blood flow serve as an alternative route for peptides and hormones of nervous tissue into the bloodstream, primarily performing neuroimmune-endocrine functions, as well as the role of an «immune watchman».

Considerable attention is paid to the biological method of controlling the number of blood-sucking insects, as it is highly selective, effective and environmentally safe.
340 reservoirs were examined within Volyn Polissia, among which 86 (14,9%) contained Simuliidae larvae with signs of bacterial lesion. Damaged larvae were recorded in small rivers and ameliorative canals, most of which, 71,5%, were mesosaprobic in terms of water quality. Bacterial infection was detected in the larvae of 10 species: S. pusillum, S. nigrum, S. equinum, S. erythrocephalum, S. ornatum, S. dolini, S. noelleri S. paramorsitans, S. promorsitans, S. morsitans.
Оn Volyn Polissia a study was conducted on the effectiveness of reservoirs delarvation with three preparations based on Bacillus thuringiensis H14 bacteria - bactoculicide, bactolarvicide and BLP-2477. Experiments were carried out in ameliorative canals with a bed up to 2 m wide, 0.5 m deep and with a current speed of 0.7 m/s, which were densely populated by preimaginal phases of black flies. Treatment of the reservoir with preparations was carried out in two ways. The first consists in a one-time introduction of the entire dose, the second - in a gradual introduction of the dose over 6 and 24 hours.
It was established that a single application of the entire dose of the preparation ensures only partial death (up to 75%) of black flies. An uneven death of larvae was registered in the entire area of treatment. The method of gradual introduction of the preparation, when it is washed out over 6 or 24 hours, is more effective (death of larvae up to 100%).
To the quantity control of the black flies pre-imaginal phases development, preparations BLP-2477 and bactolarvicide are recommended as the most effective. The optimal dose for the death of black flies larvae at a distance of up to 1.5 km in ameliorative canals with width of up to 2 m, depth of 0.5 m and a flow speed of 0.7 m/s should be considered 400 g of the preparation.
The deaths of non-target hydrobionts, caddisflies, mayflies, molluscs, and fishes were not registered.

The presence of a variety of symptoms that last longer than the acute phase of COVID-19 is called post-COVID syndrome (PCS). Musculoskeletal, digestive (i.e., diarrhea), and neurological symptoms, including depression (according to the Zung scale), were most commonly observed in patients with PCS. Fatigue/muscle weakness, dyspnea, pain and discomfort, anxiety/depression, and impaired concentration were observed in more than 20% of patients. PCS is mainly characterized by musculoskeletal, lung, digestive and neurological disorders, including depression. PCS is independent of the severity of the acute illness and the humoral response. During and after infection with COVID-19, patients are at increased risk of developing depression and anxiety.
Many people with COVID-19 are at risk of long-term impairment and disability, especially in critical cases. Symptoms after acute COVID-19 are highly variable and varied. Not only the stressors associated with the consequences of the infection of COVID-19, but also the measures taken against the pandemic can lead to the development of new mental illnesses or the worsening of existing mental health disorders. Depressive disorders affect physical, mental, and social functioning and increase the risk of premature death. People who survived COVID-19 had a high prevalence of acute psychiatric complications. Common neuropsychiatric sequelae following SARS-CoV-2 infection included fatigue, sleep problems, anxiety, depression, post-traumatic stress disorder, headache, raving, and cognitive impairment. Additional diverse manifestations of COVID-19 have been noted, such as delirium, peripheral neuropathy, dizziness, and mood disorders.

Published: June 2024

Ecopetrol, based on the results obtained in the study "The Effect of Diesel Properties on the Emissions of Particulate Matter" (Bello et al., 2000), reformulated the diesel fuel distributed in Bogotá, becoming it lighter and with a lower sulfur content. In order to evaluate the environmental benefits that the reformulation of diesel fuel generate in Bogotá, Instituto Colombiano del Petróledo (ICP), with the assistance of Emissions Research and Measurement Division (ERMD) from Environment Canada, arranged a research project to determine the changes in CO, THC, NOx, CO2 and Particulate Matter emissions. The research program was developed in two steps. First one, developed in Bogotá, involved a fleet test with 15 public service buses that normally operate in Bogota’s Savannah, using a portable emissions sampling technology developed for ERMD (DOES2) and following a representative transient driving cycle. Second step, carried out in ERMD’s Heavy-Duty Engine Emissions Laboratory in Ottawa, tested a 1995 caterpillar 3406E 324,5 kW (435 HP) diesel truck engine on the same samples of Colombian diesel fuels used in the fleet tests performed in Bogotá, baselining the tests with a Canadian Commercial Low Sulfur Diesel Fuel.  The two commercial Colombian diesel fuels used had the following properties: High Sulfur Diesel (HSD), with 3000 ppm (0,3 wt%) of sulfur and a Final Boiling Point (FBP) of 633 K and the new reformulated diesel fuel, with 1000 ppm (0,1 wt%) of sulfur and FBP of 613 K, which is currently been distributed in Bogotá. Fleet test show small reduction on CO, THC and TPM, and small increments on CO2 and NOx, but with not statistically significant results, while engine testing shows an strong reduction of 40,8% in TPM when you use the new reformulated diesel fuel (0,1wt% of sulfur) instead of high sulfur diesel.

The study of water quality is important over time because it is an essential element for human beings, it has been vital for their survival, territorial expansion, and socioeconomic development. The water of the Monjas river present contamination issues, mainly due to human activities such as agriculture, animal husbandry, and gray water discharges that alter their chemical, biological, and physical properties. The purpose of this research is to evaluate whether the water conditions are suitable for agricultural use, applying the Water Quality Index (WQI) methodology, which requires a study in the laboratory for fecal coliforms, dissolved oxygen, pH, biological demand for oxygen, nitrates, phosphates, dissolved solids, turbidity, and temperature. Samples were taken at six sampling points along the riverbed. Results were compared with the parameters described by TULSMA (Texto Unificado de la Legislación Secundaria de Ministerio de Ambiente), and FAO (The Food and Agriculture Organization of the United Nations) environmental regulations. Higher values were obtained for fecal coliforms, and biochemical oxygen demand that exceeded the maximum permissible limits with respect to the rest of the parameters examined. In this study, the WQI ranged from 26 to 50, classifying the water quality of the Monjas river as unsuitable. It implies that it is not appropriate for agricultural use due to the contamination that it could cause to the crops. The main reasons for this could rely on the presence of fecal matter of human, and animal origin, fertilizers, pesticides, and household waste.

"A Component Part of the General Struggle of All the People of the World": Finally Got the News between Black Detroit and the World Revolution
Authors: Williams Zachary
Published: June 2024

Abstract: The documentary Finally Got the News (dir. Stewart Bird, Peter Gessner, and René Lichtman, 1970) remains a lasting and inspiring document of the League of Revolutionary Black Workers and the cycle of militant Black working-class struggle that gripped the Detroit auto industry during the Long Sixties. The conditions of the production process, however, suggest a League that was slowly breaking apart under the weight of contradictions both internal and external. For the Marxist-Leninist bloc in the League's leadership, the basis of this contradiction was ideological, between their own analysis of Black racialization and racial oppression as grounded in racialized super-exploitation and an amalgam of competing Black nationalist perspectives they viewed as insufficiently revolutionary. The Marxist-Leninists saw the documentary as an opportunity to consolidate their authority within the organization and build a communist hegemony in the Black working-class movement. This evaluation of the terms of struggle, unfortunately, was based on a flawed equivalence between theoretical perspective, ideological line, and practical political strategy and tactics. In pursuing this plan, they actually exacerbated existing tensions with other leaders and the rank-and-file membership, inadvertently contributing to the dissolution of the League soon after.
An American Dilemma? It's Happening in Detroit, or the Swedish History of Finally Got the News (1970)
Authors: Sundholm John
Published: June 2024

Abstract: This paper presents the Swedish history of the legendary documentary Finally Got the News (1970), a collaboration between Newsreel and the League of Revolutionary Black Workers in Detroit. Through an analysis of the re-edited print made by Swedish TV in 1971 and archival research on the League member Glanton Dowdell, who distributed the film in Sweden, the paper sets out to both correct some of the previous research and reveal how racism was a blind spot in Sweden, which at that time appeared to be the model of a politically progressive country that engaged with the American Black Power movement.
Finally Got the News , on Another Continent
Authors: Gambino Ferruccio
Published: June 2024

Abstract: For many of its initial viewers, Finally Got the News gave food for thought to those who had paid little or no attention to the tens of millions of unwaged and waged workers of non-European origins who have toiled for capitalism in the modern era worldwide. The distinctive feature of Finally Got the News is that it shows Black Detroit, in the aftermath of the 1967 Rebellion, taking freedom of speech seriously and speaking for itself without any deference to condescending powers. The film made a particular impact on young working class and student activists who gathered for two days of political debate on an isolated farm near Florence in August 1970, a meeting organized by the Italian extra-parliamentary group, Potere Operaio (PO). One of the leaders of the League of Revolutionary Black Workers, John Watson, introduced the film with his history of the self-activity of African American laborers in the United States. In the end, many found the translation of Watson's ideas on screen more compelling than Watson's own in-person presentation. The Florence screening of Finally Got the News ended with big applause. I recount the events herein and put the film in dialogue with revolutionary currents throughout postwar Europe.
An Interview with John Watson
Authors: Georgakas Dan
Published: June 2024

Abstract: The following interview was originally conducted in September 1970 and published in November of that year in Quaderni Piacentini , a radical Italian periodical founded in 1961 by Piergiorgio Bellocchio and in print until 1984. In the same issue that featured this interview of John Watson there appeared an article by Eldridge Cleaver, a leading member of the Black Panthers, and a report on the Weather Underground, among other articles. While such features demonstrate the internationalism of the periodical's radical interests, they also demonstrate, in succinct fashion, the ideological diversity of Quaderni Piacentini 's pages. Following a short introduction, Watson discusses the Marxism-Leninism of the League of Revolutionary Black Workers, the difference between the revolutionary potential in the United States and that in Europe, the relationship between the struggle among black workers and white workers, and the various projects and struggles taken on by the League.
Part II–(Re)imagining Cinematic Histories of Africa: African Women, Cinema, and the Tale of Kadidia Pâté
Authors: Ellerson Beti
Published: June 2024

Abstract: "Le dit du cinéma africain" (The Tale of African Cinema), by the inimitable griothistorian Amadou Hampâté Bâ, is an extraordinary tale of Mali's early encounter with cinema, revealing an equally fascinating story of an early instance of an African woman and cinematic spectatorship. In his tale, he recounts in her own words, his mother Kadidia Pâté's first experience with cinema. This enchanting and edifying rendezvous with the moving image provides us not only with a unique introduction to the histories of African women's encounter with cinema but also to the trans-global nature of these cinematic experiences. As Toni Cade Bambara reminds us, as early as 1897, "operators for Lumière, Meliès, and Edison were presenting, in various countries, programs of flickers shot from all over the world." And in the case of Mali in this tale, movies imposed on the inhabitants who refused to look. This section relates her extraordinary story.

An introduction to ethnomathematics defines it as mathematics practiced among identified cultural groups. Ethnomathematics has a positive impact on the learning process, both as a moderate approach and as an approach to enhance numeracy literacy skills, for example. Previous researchers have conducted several studies on the ethnomathematics approach to mathematics education. However, the analysis presented has been highly varied. This study aims to determine the correlation between the ethnomathematics approach to mathematics education and students' mathematical abilities. This research utilizes a meta-analysis method, which combines multiple experimental studies that gather the effectiveness of ethnomathematics-based learning and regular learning in improving students' mathematical abilities. Relevant studies were searched through electronic resources from the National Library of Indonesia (Perpusnas) database using predetermined keywords. A total of 52 studies were obtained from the search, and eleven studies were selected based on inclusion and exclusion criteria. Meta-Mar was used to determine the combined effect size by analyzing the selected studies. This research indicates that the combined effect size of implementing ethnomathematics-based learning to enhance mathematical problem-solving abilities is 0.94, classified as a moderate effect. Therefore, it can be concluded that the ethnomathematics approach to mathematics education is related to students' mathematical abilities. Statistically, the implementation of the Ethnomathematics Approach in Mathematics Education is also influenced by study characteristics at the educational level.

This study examined the larvicidal and feeding deterrent properties of extracts from Dieffenbachia maculata against Spodoptera frugiperda (Fall army worm) in growing maize. A 9 m x 7 m space in the green house was divided into forty-two plots of 1 m by 0.75 m with 0.5 m discard between rows. This is to allow for a 2 x 3 x 4 factorial experiment replicated three times. Maize seeds were sown at two seeds per hole at a spacing of 90 cm by 60cm in each plot. Each plot was barricaded with wire mesh to prevent the migration of larvae from plot to plot. The irrigation system in the greenhouse supplied equal volume of water at the base of the maize seedlings every morning. Infested maize plants were treated with different Dumb cane plant extracts at the concentration of 25ml/l and30ml/l along with positive and negative controls. (The positive control was treated with Cypermethrine at 3l/ha) to compare the effect of concentrations on the fall army worm activity. In this experiment, the numbers of leaves affected was assessed every week and recorded. Leave perforation index was calculated. Dead armyworms were observed by prodding the larvae for movement and were recorded. Plant vigour was obtained by measuring plant height and the number of leaves formed. Effect of the worm on yield was determined by comparing total yield from sampled maize plants and this was compared to expected yield from the variety of maize used for the research. The positive control group exhibited a significantly lower level of infestation after treatment with a corresponding yield increase, (16.06% and 80.14%) respectively when compared to the treated groups. Similarly, leave extract using acetone at 30ml record significantly better results with 17.73% level of infestation after treatment application and 66.44% yield increase. This was closely followed by leaf extract using methanol at 30ml with significantly lower level of infestation and increased yield respectively. (21.35% and 60.42%). Conversely, the lowest value was recorded for the negative control. Among the extract treatments, the leaf extract using acetone at 30ml showed the highest efficacy in reducing infestation levels and demonstrated the most significant increase in maize yield. In this study, it was observed that application of the 30ml leaf extract of Dumb cane using acetone was effective and significantly increased army worm larval mortality, reduced leaf damage, and increased maize grain yield compared to the untreated control. The results indicated that the extracts from dumb cane leaves and stems exhibited promising capacity in the control of Fall army worm in maize. Further research is warranted to optimize the application protocols and evaluate any residual effects of the extracts on maize grain and ecosystem dynamics

Mitochondrial DNA (mtDNA) is located in the mitochondrial matrix, in close proximity to major sources of reactive oxygen species (ROS) in the cell. This makes mtDNA one of the most susceptible components to damage in the cell. The nuclear factor E2-related factor 2/antioxidant response element (Nrf2/ARE) signaling pathway is an important cytoprotective mechanism. It is well-studied and described that Nrf2 can regulate the expression of mitochondrial-targeted antioxidant systems in the cell, indirectly protecting mtDNA from damage. However, the Nrf2/ARE pathway can also directly impact on the mtDNA repair processes. In this review, we summarize the existing data on the impact of Nrf2 on mtDNA repair, primarily base excision repair (BER), as it is considered the main repair pathway for the mitochondrial genome. We explore the crosstalk between Nrf2/ARE, BRCA1, and p53 signaling pathways in their involvement in maintaining mtDNA integrity. The role of other repair mechanisms in correcting mismatched bases and double-strand breaks is discussed. Additionally, the review addresses the role of Nrf2 in the repair of noncanonical bases, which contribute to an increased number of mutations in mtDNA and can contaminate the nucleotide pool.

After operative correction of adduction in the first stage of operative treatment (ligamentotomy, tendon elongation etc) of neglected congenital talipes equino-varus in children aged 4–6 years, some defect of the skin on medial side of the foot arises when correct position is assumed. The author covers this defect by pedicled skin graft from the dorsal surface of the foot, using the opportunity that on lateral surface of the inverted foot there is an excess of skin in the form round protuberance covering the cuboid bone and tuberosity of the fifth metatarsal. By flattening this round protuberance the area of the skin graft increases in such extent that not only the defect may be easily covered but the whole graft can be sutured to the edges of the operative wound.
