tráfico estadounidense de esclavos al Río de la Plata y los circuitos de la plata más allá del Atlántico, 1798-1809
Authors: Borucki Alex
Published: October 2022

Si bien la trata de esclavos llevados por buques de Estados Unidos hacia el Río de la Plata duró solo doce años, entre 1798 y 1809, los comerciantes estadounidenses enviaron más cautivos directamente desde África a Buenos Aires y Montevideo (en lugar de hacerlo de manera indirecta a través de Brasil) que cualquier otro grupo nacional de mercaderes entre 1777 y 1812. Este artículo examina las conexiones de la trata de esclavos con la circulación de plata hispanoamericana más allá de las colonias españolas, en tanto la plata fue el principal medio de intercambio de las transacciones realizadas por este tráfico. Esta historia también conecta el Atlántico con el Pacífico, pues buena parte de los cautivos que desembarcaron las naves esclavistas de Estados Unidos en el Río de la Plata se redirigió hacia Lima a través de Chile.

Published: October 2022

Human metapneumovirus (HMPV) is a virus from the paramyxovirus family identified in 2001. It is the second most common cause of lower respiratory tract infection in children after respiratory syncytial virus. In adults, it is mostly seen in the elderly population, immunosuppressive patients or those with a concomitant chronic disease. Human metapnemovirus can cause various clinical pictures ranging from a simple upper respiratory tract infection to bronchiolitis and asthma attack, from severe pneumonia to encephalitis and acute respiratory distress syndrome. In the case of viral infection in adults, especially during the Covid-19 pandemic, clinical and laboratory findings are similar, so it should be kept in mind in the differential diagnosis. This article is presented to draw attention to the inclusion of HMPV in the differential diagnosis of a 65-year-old female patient who applied to the practice with the complaints of high fever, cough, wheezing and headache during the Covid-19 pandemic. It has become important to detect the causative agent with multiple molecular tests and direct antigen tests in terms of differential diagnosis in respiratory tract infections, which are generally seen in adults during the pandemic. After the viral agent is determined with the diagnosis of the causative agent, the infection can be controlled more easily with the right treatment and the unnecessary use of antibiotics can be prevented.

Published: October 2022

A person can develop addiction to many kinds of substances. Methamphetamine is the second most widely abused drug worldwide. Long-term methamphetamine usage may cause social, psychological, and physical problems. Long-term effects (such as weight loss, memory loss, tremors, convulsion, psychosis, paranoia, hallucinations, Parkinson's-like symptoms, and cardiovascular collapse) and short-term effects (such as euphoria, dilated pupils, insomnia, reduced appetite, increased blood pressure ) are listed and, brain damage and mental problems due to methamphetamine abuse are briefly mentioned in this text. The severity of withdrawal symptoms varies from person to person. Unfortunately, there is no exact cure for methamphetamine abuse. This is not a systematic review.
Dietary supplements and Side Effects: Persistent Atrial Fibrillation
Authors: GOKDEMIR Ozden , KARAMAN ULUTAN Aysegul
Published: October 2022

Dietary supplements, also known as food or nutritional supplements, are intended to compensate for nutrient deficiencies or to maintain the proper nutrient balance in the diet. As dietary supplements are not permitted by law to be marketed as a treatment, prevention, or cure for any disease; only drugs are permitted to make such claims physicians should be aware of the fact that individuals using these supplements could affect their health.

A 22-year-old man presented to the emergency department with palpitations and dyspnea of recent onset (>2 hours). His medical history revealed nothing noteworthy. His physical examination revealed tachyarrhythmia. His electrocardiography revealed an AF speed of 130 beats per minute (ECG). In this case, a young man who was using Jack3D and diagnosed with atrial fibrillation has been presented which has been unique.

Despite the fact that natural products in food supplements are more expensive than synthetic ones, the majority of people prefer them. This could be because they believe natural products are more beneficial and safe for their health. As a result, this is a significant public health issue that also poses a financial risk.

Published: October 2022

Objectives: Hematological malignancies presenting with febrile neutropenia constitute an important health issue all over the globe. In this study, we aimed to elucidate the prognostic factors of febrile neutropenic patients with hematological malignancies and to investigate the causes of mortality.

Method: This research had a retrospective nature. A total of 174 febrile neutropenia patients ≥ 18 years of age hospitalized have been enrolled in the study. Patients enrolled in the analysis were determined according to the American Society for Infectious Diseases 2010 Febrile Neutropenia Diagnosis and Treatment Guidelines. Accordingly, neutropenia was defined as an expected decrease in the absolute neutrophil count (ANS) to < 500 cells/mm³ or < 500 cells/mm³ over the next 48 hours and body temperature over ≥ 38°C.

Results: A total of 174 patients have been included in the analysis and 32 (18.5%) died while 142 (81.5%) did not develop mortality. When the statistically significant results are evaluated according to multivariate analysis; Age, Crp, MASCC, acute renal failure, and hypotension were similar in both groups. On the other hand, when univariate statistically highly significant results are evaluated according to multivariate analysis; the Presence of urinary catheter, diagnosis of bacterial pneumonia, and ANS not increasing after 1 week were found to be statistically significant in the mortality group.

Conclusion: The results of the study showed that in febrile neutropenic patients, mortality was increased by 6.7 times by a diagnosis of bacterial pneumonia, 245.6 times by the absence of ANS elevation, and 13.9 times by urinary catheterization.
Inquiry-based learning on the example of the IB International School Programme of Inquiry
Authors: Koterwas Agnieszka
Published: October 2022

Introduction. Inquiry-based learning is perceived as one of the most effective teaching methods, an example of the implementation of constructivism in educational practice with the dominant role of a cognitively activated student, who, analogous to the work of a scientist, has the opportunity to pose questions, hypotheses and research problems and to construct strategies to solve them through the use of a number of various research tools, and finally to present, in a variety of forms, the results of their research. However, in Poland, this approach to teaching is a basically unrecognized area, especially at the level of early childhood education.
Purpose. The purpose of this article will be to present a description of the inquiry-based learning (IBL) method, indicate its key elements and implications using the example of one elementary school with the IB programme.
Materials and Methods. The subject of the analysis are publications and educational materials on the inquiry-based learning method, as well as the analysis of the content of documents presenting the plan and evaluation of the school’s teaching work developed by a team of early childhood education teachers from a non-public international elementary school in Poland with the IB programme.
Results. The IBL method with the system support offered by the IBO Foundation can be implemented in early childhood education in the conditions of the Polish education system.
Conclusions. The example of the IBL method implementation in the world of school practice proves that teaching in Poland can be different. There is a need for activities aimed at promoting such didactic solutions.
Finite element analysis of thermal stress in Cu2O coating synthesized on Cu substrate
Authors: Shorinov O.
Published: October 2022

The paper aims to find the magnitude and nature of thermal residual stresses that occur during cooling of a copper sample with a thermally synthesized oxide layer of Cu2O.

Thermo-mechanical analysis was performed by the finite element method using Ansys Software. The results of thermal analysis were used to study the resulting stress-strain state of the thin film/coating system after cooling.

Based on the modeling results, the paper determined the most stress-strain areas of the sample with a coating, which are the free edges of the interfaces between the copper substrate and the Cu2O oxide layer.

The main limitations of the study are the use of certain simplifications in the condition setup, for instance, uniform cooling of the thin film/coating system, homogeneity and isotropy of substrate and thin film materials, invariance of their properties with temperature changes, etc.

The results obtained can be used to control the stress-strain state of the thin film/coating system and prevent deformations and destruction of thin-film structures during their production and operation of products with them.

The study of new promising methods for the formation of oxide nanostructures, for instance in a plasma environment, requires a sufficient theoretical basis in addressing the origin and development of stresses.

Digital Transformation Principles Driving Journeys toward Educational Resilience
Authors: Barr Michael , Murch Ron , Chatterton Peter
Published: October 2022

The implementation, support, and ultimate success of digitally-informed innovations to teaching and learning practices requires focused intentionality whose approach is grounded in academic rigour, practical experience and organizational maturity. The success of technology-supported innovation in higher-education teaching and learning practices, driven by external factors like COVID and the resultant economic challenges, will be explored in relation to teaching faculty and administrative leaders developing and maintaining positive motivation towards change including addressing major organizational challenges. // Innovation, Change and Transformation // As Senior Instructor Emeritus, Ron Murch has more than 45 years of experience with the University of Calgary’s Haskayne School of Business. Ron maintains that digital transformation requires faculty members to adopt the requisite innovations in practice and technologies as imagined by the Technology Acceptance Model and expanded upon by two key principles - each new practice or technology must have recognizable and positive value for the individual who is changing; and it cannot be too difficult for the adopter to work with. // Guiding Principles // Dr. Peter Chatterton is a Chartered Physicist and digital innovator. He worked in roles such as critical friend, evaluator and change management consultant with the UK Government’s multi-million £s HEI digital innovation and transformation programmes during 2000-2020. From this experience, Peter asserts that HEIs can be both creative and effective at digital innovation. However, scaling-up and embedding such innovations to build long-term resilience and effect digital transformation across the institution invariably faces numerous challenges. These are explored through the lens of seven key guiding principles for digitally transforming learning programmes for open and flexible learning. // Commitment and Motivation // Michael Barr is Chief Information Officer at the Southern Alberta Institute of Technology in Calgary, Alberta, and a doctoral student in higher education management at the University of Bath, UK. Building on a theory of behavior in organizations, Michael explores the motivation process and its impact on the construction of strategic plans and the organization’s ability to deliver successful outcomes. He draws upon 28 years’ of IT practitioner experience to ground his scholarly work with practical advice and considerations for undertaking digital transformation of teaching and learning practices.
ICT Enabled Education to Empower Girls: Potentials for the Vulnerable Groups
Authors: Sultana Sadia
Published: October 2022

Financial constraints, coupled with socio-cultural construct induce vulnerability among girls in Bangladesh. This leads to them entering the labor market without skills; thus, their career becomes constricted while their potential remains unexplored. For a worthwhile life they should be empowered, which can best be done by educating them without hindering their work life. Open and Distance Learning (ODL) with the use of Information and Communication Technology (ICT) can provide such a flexible learning arrangement to working women and girls. A wide range of electronic devices at different purchasing levels can provide flexibility in the use of ICT. A retrospection of COL’s Gender initiative’s virtual workshop, ‘Upskilling Girls in ICT through Mobile Application Development’, facilitated by the author in 2020 evoked ideas and generated interest for following up with the participants regarding their use of ICT. This endeavor helped conceptualize the idea that girls of the vulnerable groups can potentially be empowered by engaging them with ICT-enabled education which can transform their lives. This study has been conducted based on both primary and secondary sources of data. Secondary sources are research materials, scholarly articles, statistics from governmental websites and official publications. Primary data were collected in two stages. Firstly, data were collected from 74 girls through structured questionnaires and focus group discussions (FGDs), who represented nine rural areas of Bangladesh. Secondly, in light of the experience and findings of these data, a follow up study of the author’s previously conducted research among girl workers of six garment factories in Dhaka Metropolitan City was carried out through questionnaire survey and FGDs. The findings of this research can lead towards further educational explorations and help develop actionable plans to significantly empower girls of the vulnerable groups.

Published: October 2022

Innovation and entrepreneurship are considered one of the most powerful driving forces for economic and social progress in our era. As a result, building a unique entrepreneurial ecosystem and transforming it into an “innovative and Entrepreneurial University” have become goals for many colleges and universities. // Innovation and Entrepreneurship are very important in Universities because they play an important role to increase entrepreneurial graduates of higher education. Global awareness of the importance of the role of entrepreneurship and innovation in the university ecosystem is in line with the growing awareness of higher education institutions, and universities, to walk the entrepreneurial path. This study aims to form an entrepreneurial university model using a systems approach, where the university should not carry its own burden in carrying out the responsibilities of a third mission to help accelerate community development. Going by the society we have found ourselves, we observed that there is a huge gap between the school curriculum and the marketplace demand. Most graduates in the marketplace are deficient in relevant knowledge, skills, and attitudes needed to solve critical problems in the workplace. // The rate and rapidity at which the African youth population has been growing are enormous and this has also been very challenging. On one side, it is enormous because if well harnessed, it could become a potential for improved African economy, production, and growth. To this end, youths could be considered Africa’s greatest asset. On the other hand, it is challenging as the resultant restiveness constitutes a threat in our universities, and unemployment fosters banditry and militancy. // In all advanced economies, Higher Education Institutions (HEI) are expected to play a vital role in encouraging innovation, entrepreneurship, and structural change. The expanding population shares the economic importance of knowledge-intensive active ties, digital transformation sweeping across all organizational borders of the globe, and the need to quickly forge efficient and innovative solutions to address pressing societal challenges, that is the demand to contribute more to innovation and to economic and societal change. // The world economic forum estimates that 15 to 20 million young people will join the African workforce every year for the next two decades. By 2030, Africa will be home to more than a quarter of the world’s population under 25, who will make up 60% of the continent’s total population. By then, 15% of the world’s working-age population will be in Africa. /

Politik Hukum dalam Proses Pemindahan Ibu Kota Negara Melalui Pembentukan Undang-Undang Ibu Kota Negara (UU IKN)
Authors: Benia Elsa , Nabilah Ghina
Published: October 2022

Pengesahan Undang-Undang Nomor 3 Tahun 2022 tentang Ibu Kota Negara (UU IKN) banyak menimbulkan pro dan kontra. Sebab, pembentukan UU IKN memiliki banyak ketidaksesuaian, seperti kurangnya partisipasi publik dan singkatnya proses pembentukan karena memakan waktu 43 hari saja. Lalu, politik hukum memiliki relevansi yang kuat dengan arah kebijakan pembentuk produk hukum. Tulisan ini menggunakan metode yuridis normatif dengan pendekatan undang-undang serta kasus. Hasil penelitian menyatakan bahwa dalam pembentukan UU IKN, politik hukum yang ada di dalamnya tidak menggambarkan kebutuhan masyarakat, terbukti dari dangkalnya analisis pada naskah akademik sampai dengan indikasi cacat formil dan materiil karena pembentukan yang terburu-buru.

Authors: Das Kuntal , Dang Raman
Published: October 2022

The field experiment on Stevia rebaudiana (SR), (Family: Asteraceae) was carried out in acid soil zone of Shimoga (Karnataka) in the year 2009 and 2010 to investigate the influence of biofertilizers on protein, moisture and ash content in the dried Stevia leaf and their correlation with swelling property, water absorption capacity and mineral element contents. Results revealed that second harvested sample (August) in first year (2009) was better for all aspects than other harvested samples and the results showed significant increase in protein content (16.22%), swelling index (SI) (5.10% w/w), water absorption capacity (WAC) (4.91 ml/g) with the treatment T8 where three bio fertilizers were applied togetherly with simultaneous moisture content varied from 6.61 to 7.18%. The significant higher correlations were observed (significant at 1%) between protein content with SI (r = 0.99), WAC (r = 0.99) and SI with WAC (r = 0.98) in 2009 harvested samples. The ash content was higher in third harvested sample (13.54%) in the year 2009 with simultaneous increased amount of Fe (6.19 mg/kg), Mn (1.24 mg/kg), Cu (0.72 mg/kg) and Zn (1.22 mg/kg) contents due to the residual effect of bio fertilizers. Nitrogen (0.74 mg/kg), P (0.40 mg/kg) and K (0.68 mg/kg) contents were higher during second harvested samples and thereafter decreased. Total phenolic content was also recorded highest (64.52 mg/g) with three bio fertilizers applied togetherly during year 2009 compared to the year 2010 (50.12 mg/g). The results suggest that the application of bio-fertilizers either single or more numbers in a balanced way may be beneficial in improving protein, phenol and mineral contents of stevia plant

Authors: Baroowa B. , Gogoi N.
Published: October 2022

Drought is one of the major abiotic stresses which adversely affect crop growth and production worldwide as water is vital for every aspect of plant growth and development. The present experiment was carried out during the growing seasons (September – December) of 2012 and 2013 to evaluate the response of black gram (Vigna mungo L.) and green gram (Vigna radiata L.) in terms of some important growth indices, biochemical traits and seed quality under drought stress. Four commonly grown genotypes - T9, KU 301(black gram) and Pratap, SG 21-5 (green gram) of Assam, India were grown in a randomized block design with three replications under stress and non-stress conditions. Stress was applied by withholding irrigation for fifteen consecutive days at vegetative, flowering and pod filling stages. Leaf area index (LAI), seed protein content and protein yield significantly decreased (p ≤ 0.01) whereas proline, total flavonoids and anthocyanin content increased significantly (p ≤ 0.01) in response to water deficiency. Among the studied genotypes, T9 and Pratap showed better tolerance capacity towards the applied drought by presenting higher values of LAI, plant height stress tolerance index (PHSI), dry matter stress tolerance index (DMSI), proline, total flavonoids, anthocyanin, lower percentage of chlorophyll degradation and finally producing high quality seeds.
Molecular Aspects of Effect of Shiga Toxin in Humans - A Review
Authors: Pal Partha
Published: October 2022

Shiga toxins belonging to a family of structurally and functionally related protein toxins serve as the key virulence factors for pathogenecity of the virulent enteric bacterial strains namely Shigella dysenteriae serotype 1 including Shiga toxin-producing Escherichia coli (STEC). S. dysenteriae type 1 isolates remain major public health concerns due to their widespread outbreaks and the severity of extra-intestinal diseases, including acute renal failure and also affects the central nervous system. Despite practicing improved hygienic conditions and regulating food and drinking water safety, the enteric pathogens are imposing a major threat in the well being of the human society. Shiga toxin on entry into host cells’ endoplasmic reticulum (ER) activates the stress response in ER and inhibits protein synthesis by catalytic inactivation of eukaryotic ribosomes. In many cell types shiga toxins trigger apoptosis. Recent studies have shown that shiga toxins induce autophagy which activates different signaling pathways in toxin-sensitive and toxin-resistant human cells. In this review the molecular basis of Shiga toxins’ effect on host cell leading to manifestation of the infection in affected individuals are discussed with an emphasis on recent findings.

A field experiments were conducted during the two summer seasons of 2015 and 2016 in saline soil (ECe = 9.0 dSm-1), at Fayoum province, Egypt to study the effect of ascorbic (AsA), as foliar application alone or combined with cyanobacteria (CB) on growth, yield, its components and nutritional status of sunflower plants variety Sakha 54. Treatments comprised 2 ascorbic acid (AsA) levels with or without seed inoculation with cyanobacteria (CB). They were 1 mM AsA, 2 mM AsA, 1 mM AsA + CB and 2 mM AsA + CB in addition to the control treatment in which seeds were not received CB and their plants were sprayed with distilled water. Results could be summarized as follows: increasing the addition of ascorbic acid concentration up to 1Mm with combination of CB increased significantly values of growth attributes (e.i., plant height, of leaves no. /plant, shoot dry weight and leaf area), photosynthetic pigments (chlorophyll a, b and carotenoids), physiological responses (total soluble sugars, proline and soluble phenols) as well as the head diameter, seed yield/ plant, 100 seed weight and seed yield (t ha-1). Also, N, P, K, Fe, Mn, Zn and oil percentage of sunflower seeds with compared to control treatment in both years. Generally, the results in most cases, demonstrate that the all parameters increased significantly by using the concentration of ascorbic acid 1Mm combined with CB in both seasons

Contaminations of industrial metals into the river possess major threat to environment. Chromium is a heavy metal which has the wide applications in tannery and electroplating industries. Above the permitted level of Chromium(VI) into surface water leads to severe health hazards. Therefore, biosorption is a technology used for the sorption of heavy metal. In this present study adsorption isotherm models was studied for the biosorption of chromium by cherry leaves. From the adsorption isotherms it was found that the experimental data fits well with the Langmuir isotherm than the Freundlich isotherm. The monolayer capacity Qm was fond to be 11.98 mg/l and the adsorption affinity was found to be positive which indicates the efficient biosorption of chromium

Authors: Jagatheeswari D.
Published: October 2022

In the present study, the morphological features of 20 taxa of the family Solanaceae were studied. The Solanaceae, or nightshades, are an economically important family of flowering plants. The family ranges from herbs to trees, and includes a number of important agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many cultures eat nightshades, in some cases as staple foods. The present observation shows that majority of Solanaceae members almost the same morphological features that of the family.

The present study was undertaken to identify the superior cabbage genotype and to examine their physical yield performance among the four cultivated genotypes namely Namdhari Seeds 183, Namdhari Seeds 160, Namdhari Seeds 35 and Tropical Sun Plus, grown in plains and higher altitude of Kerala. Study revealed that significant differences were observed in yield levels of cabbage and it was ranged from 22.6 – 29.3 kg /16m2 in hills and 1.27 – 22.06 kg /16m2 in plains. Among the cabbage genotypes, NS 183 was found to be the best for hilly region in terms of higher head yield (22.06 Kg /16m2), head weight (729.6 g), head height (11.1 cm) and early maturity. Similarly, Tropical Sun Plus exhibited better performance in plains in terms of higher head yield (22.06 Kg /16m2), head weight (729.6 g) and head height (11.1 cm). The individual genotype which exhibited the superior performance in hills and plains were selected and compared for the general biochemical characters like Moisture content, acidity, ascorbic acid, protein, phosphorus, calcium and potassium. Finally, the study found that, the genotype grown at hill (Tropical Sun Plus) was recorded a higher biochemical characters than genotype grown in plains (Tropical Sun plus). Similarly, hill grown genotype (NS 183) recorded a higher biochemical characters than the plains grown genotype (NS 183).

This study investigated those factors which influenced the adoption of Moringa olefera as water purifier by the farmers in Kaduna state. Data were collected with the aid of structured questionnaire from 30 respondents. The data were analyzed using descriptive statistics and logit regression model. The results showed that the respondents had one form of education or the other. About 90 percent were married average household size of 10 persons per household. About 73 percent adopted Moringa oleifera water purification. Socio-economic factors influencing adoption of Moringa oleifera water purification were age, education, extension contact and membership of cooperative. The study therefore recommends that farmers should form themselves into association because such association will aid in collective soliciting for government assistance, NGOs and other funding agencies. Also, more awareness should be created by the extension agents on the importance of Moringa oleifera seed powder in rural development.
