Nombres deturpados en los «Coloquios satíricos»: los resortes humanísticos de Antonio de Torquemada
Authors: Malpartida Tirado Rafael
Published: March 2023

En el presente trabajo se examinan diez casos de nombres deturpados, tanto por parte de los componedores antiguos como debido, sobre todo, a las malas lecturas de los editores modernos, en los Coloquios satíricos (1553) de Antonio de Torquemada. Se pone así de manifiesto la complejidad de los códigos humanísticos en los que se mueve el autor y se alerta sobre la responsabilidad que representa editar un texto de esas características.
La «Égloga intitulada el Dios Pan» de Diego Mexía de Fernangil: la «Epístola y Dedicación» a D. Diego de Portugal
Authors: Martínez Martín Jaimé José
Published: March 2023

Dentro de la segunda parte del Parnaso antártico de Mexía de Fernangil, se encuentra la “Égloga intitulada el Dios Pan”,          que no ha merecido aún la suficiente atención de la crítica. Dicha composición está precedida por una “Epístola y dedicación”, dirigida a Don Diego de Portugal, presidente de la Real Audiencia de Charcas, que mezcla la función proemial con el carácter y la estructura epistolar que marcaba el ars dictaminis. El poema manifiesta la evolución que había sufrido el género a finales del s. XVI en la medida en que deja de ser un medio de comunicación familiar entre dos amigos, para convertirse en un discurso político a una autoridad advirtiendo en este caso, de que España podría perder su dominio de Perú si no cumple con el compromiso adquirido de cristianizar a los indios.
Poly-Vinylidene Fluoride (PVDF)/ Span-85 Membrane for Omega-3 PUFA Concentration: Membrane Performance and Fouling Analysis
Authors: Ghasemian Samaneh , Sahari Mohammad Ali , Barzegar Mohsen , Gavlighi Hassan Ahmadi , Abedini Reza
Published: March 2023

Abstract: For increasing the efficiency of the omega-3 production, the effect of span-85 surfactant as a hydrophobic agent (0, 1, 2, 3 and 4 wt%) on the formation of a porous structure in a sub-layer PVDF membrane was studied. Also, the cross-sectional morphology of PVDF membranes was analyzed using scanning electron microscopy (SEM) and the surface property was evaluated using contact angle test. The capacity of the membranes to concentrate omega-3 was examined by the filtration of lantern fish oil. Also, the fouling of the membrane caused by oil filtration was evaluated. All filtration tests were performed in batch mode. Results of the SEM images demonstrated that the addition of span-85 resulted in the forming of a membrane with a denser and more hydrophobic structure. The addition of 2 wt% span-85 increased the omega-3 concentration, while the higher level of span-85 showed a negative effect. The best efficiency of the membrane was 42.64 wt% which was obtained by PVDF/2 wt% span-85. This efficiency was about 11% higher than the control PVDF (0 wt%). Taken together, the presence of span-85 affected the phase inversion process during the membrane formation, which improved omega-3 concentration. Moreover, the more hydrophobic surface of the membrane resulted in higher cake formation.
Polish Archaisms against their Equivalents in Bulgarian
Authors: Sotirov Petar
Published: March 2023

The subject are Polish archaic words whose equivalents are in active use in modern Bulgarian. The aim is to reveal the composition of this group of archaisms and to show the main reasons that led to the Polish-Bulgarian asymmetry in terms of archaism. The conducted research shows that about 140 lexemes that have been archaized in Polish are present in Bulgarian. Among them, lexical and semantic archaisms prevail, while archaic words are in a smaller number. The thematically studied archaisms belong mainly to categories related to human, for example, to physical and mental characteristics, to everyday life or to interpersonal relations. By origin, archaisms are both native and borrowed words. From a formal point of view, Polish archaic words and their modern Bulgarian counterparts are identical, with minimal or more divergence. From the point of view of semantics, most Polish-Bulgarian lexical pairs have the same meaning, there are also pairs with a greater or lesser meaning divergence consisting in broadening or narrowing the semantics of the Bulgarian word compared to the Polish one. The reasons that contributed to the occurrence of the Polish-Bulgarian asymmetry in the field of the archaization of lexis are not strictly linguistic in nature, but represent the social, historical and political aspect of the language. They reflect the way in which scientific terminology was developed, social attitudes towards influences from foreign languages, the specificity of social relations and the process of shaping the standard language in both countries.
Determinants of Regionalism in the Collection of Stories by Helena Romer-Ochenkowska Tutejsi (1931)
Authors: Fedorovič Irena , Davlevič Miroslav
Published: March 2023

The object of research is a collection of short stories by Helena Romer-Ochenkowska (1875–1947) titled Tutejsi (Warsaw 1931). It is the third series of short stories by a famous Vilnius writer, poet and journalist, which is devoted to regional issues. The protagonists of the stories are native inhabitants of the Lithuanian-Belarusian border, people of different nationalities (Poles, Belarusians, Lithuanians, Jews) and of various origins (wealthy and poor nobility, peasants, officials). The stories takes place during the years of World War I and in the interwar period, when some of the Lithuanian-Belarusian territories became part of the Second Polish Republic. The indigenous people of the borderland were shown in opposition to “strangers” – German soldiers and former Russian officials and clergy. The most important determinant of regionalism, as exemplified by the collection of Tutejsi stories, is linguistic distinctiveness, visible in the author’s narrative and in the characters’ individualized language. There are regionalisms and dialectisms in the language of the heroes typical of the North-Borderlands Polish language. Based on the methodology of cognitive linguistics, the authors of the article also distinguished several other concepts that characterize regionalism, which are: local territory / patriotism; landscape; customs / traditions; games / songs; costumes. The results of the research confirm the correctness of the scholars’ opinion that people of the borderland tend to position themselves as locals and maintain a sense of their own separateness.
The Contemporary Russian Patriotic Song as a Phenomenon of a Post-Traumatic Society’s Condition
Authors: Lassan Eleonora
Published: March 2023

The author has addressed both Soviet and post-Soviet song discourse a number of times already, as it is in the song discourse that one can discern the reflection of the ideological attitudes on the one hand and a certain indicator of how the spirit of the times changes on the other. The 2000s increased the impact channels of the song genre by adding the visual channel to the ones already existing; that is, a truly popular song is disseminated in clips. There appeared a new kind of a “civil” song in the Russian song space. It explicitly coincides with the propagandist trends, either the ones being created or the ones that have already been set. This song discourse is full of ressentiment motives that have rallied the present-day Russian authorities and a certain part of the population. Their aggressively advancing potential is related to the traumatic condition of the society experiencing a particular shock caused by the feeling of the loss of the erstwhile grandeur of the country. The author deals with the functions of such a propagandistic song that can be characterized as an additional propagandistic narrative on the examples of Gazmanov’s and Bichevskaya’s songs.

Authors: Hubina V.H. , Pokalyuk V.V. , Verkhovtsev V.G. , Yatsenko V.G. , Zaborovskiy V.S.
Published: March 2023

The major and minor element compositions of the tailings at the Kryvyi Rih processing plants (i.e., Inguletsky, ArcelorMittal Kryvyi Rih, and Central) were studied. A good relationship between the composition of the tailings and the mined ore, which was to be enriched, was confirmed. The main trends in the techno geochemical changes in the process of enrichment were determined. Differences were measured of the tailings composition between various processing plants of the Kryvyi Rih basin. That is, the tailings from the Ingulets plant are more ferruginous with an iron content of 23.7 wt % and are almost twice as high compared to those of the Central and ArcelorMittal Kryvyi Rih plants. Tailings from ArcelorMittal Kryvyi Rih are more carbonaceous and aluminous and have low iron and silicon contents. Tailings of the Central plant are more siliceous and have minimum of alumina and carbonates and have the average iron content. In terms of the major elements, the tailings are generally enriched in silicon, aluminum, manganese, magnesium, calcium, sodium, potassium, phosphorus, sulfur, and depleted in iron and titanium, compared to the original ore. In terms of minor elements, the tailings are generally enriched in the some lithophile (including rare earth) elements Sr, Y, Sc, Li, and partially Zr, and depleted in elements that are concentrated in magnetite, Ni, Th, U, and Ge, compared to the original ore. The chalcophile elements Cu, Pb, Zn, Ag are characterized by an inhomogeneous and variable distribution. The most significant among them is Zn, which can have significant concentrations (up to 230 g/t in the tailings). These results can be used to determine the directions of tailing using and to assess the impact of tailings on the environment.
Cristocentrismo e assoluti morali nell’enciclica «Veritatis splendor»
Authors: Melina Livio
Published: March 2023

La questione del cristocentrismo dell’enciclica Veritatis splendor non riguarda appena la cornice teologica di un nucleo dottrinale che apparterrebbe solo all’etica razionale. Lo studio mostra come esso sia il perno dell’insegnamento etico, collegando così intimamente la dottrina sugli assoluti morali con il cuore cristiano della morale. Dopo aver tracciato una panoramica dei percorsi del cristocentrismo nella teologia morale cattolica, l’Autore delinea i tratti cristocentrici dell’enciclica di San Giovanni Paolo II sui fondamenti della morale, mostrandone quindi l’attualità in un confronto critico con le proposte recenti di un “nuovo paradigma” per l’etica teologica.

Published: March 2023

The biological macrofouling characteristics and electrochemical corrosion behavior of structural steel AH36 in natural seawater were studied continuously for 12 months at Hon Tre Island, Nha Trang – Vietnam. Electrochemical corrosion properties were studied using a PPGS-HHMC12 multi-channel device produced by the Institute of Chemistry, VAST. Tests were conducted at depths of 0.6 m, 1.8 m, and 3.0 m; under anti-macrofouling control, rotary movement, and under laboratory conditions as a comparison option.
The results showed that macro-fouling formed and grew rapidly in both quantity, size and biomass in the next 3 months, then slowly and stably increased to about 8 months (6.06 kg.m-2). The OCP shifted to a positive potential, then reached a stable value of about -550 mV during the rest of exposure time. The corrosion current density decreased sharply from the first month to the fourth month, then reached a stable value of about 10 µA.cm-2 in next months of testing. The corrosion rate of AH36 steel in natural seawater in the field was higer than that under laboratory condition, which could be explained by the interaction of many factors such as dissolved oxygen, biofouling, water current, solar radiation
Design and implementation of a low cost optical based paint viscosity control device
Authors: Pham Thi-Thu-Hien , Phan Quoc-Hung , Nguyen Duy-Anh , Le Ngoc Bich
Published: March 2023

In this study, a full-scale prototype of a water-based printer’s paint viscosity control device was proposed and conducted. Specifically, a novel approach of low-cost paint viscosity determination by exploiting the optical sensing method was proposed and a full-scale prototype was developed to exhibit the proposed concept. The feasibility of the proposed device was demonstrated by measuring the accuracy, setpoint control deviation and estimating its development cost. An accuracy of 1.5 cSt and a standard deviation of 1 cSt were recorded by comparing the measured viscosity data with the Zahn cup measuring method. The viscosity control results at a setpoint value of 40 cSt gave a variation of 0.8 cSt. The convergence time from initial 45 cSt to 40 cSt viscosity was 10 minutes. The developed cost was excessively competitive and was only one-fifth of the comparable commercial products. Furthermore, the device had solid and lightweight features, making it straightforward for portable applications.

Published: March 2023

The combination of jute fibres and polyamide 11 (PA11) to produce full biocomposites is expectance of scientists due to many benefits of both these materials such as high mechanical performances and environmentally friendly behaviors. Unfortunately, there is scarce published research on these bicomposites uptil now. In order to improve the interfacial interaction and adhesion between jute fibres and PA11 resin matrix, an important key in the fabrication of the composites. In this study, a combination of alkaline treatment and Tetraisopropyl orthotitanate (Tip) modification was employed to modify the surface of jute fibres. The deposition or grafting of TiO2 nanoparticles was proved by using Fourier transform infrared (FTIR), scanning electron microscopy (SEM) observations and energy dispersive X-ray spectroscopy (EDS/EDX) analysis. The improvement of the interfacial interaction and adhesion between surface modified jute fibres and PA11 resin as well as high performances (mechanical properties, thermal oxidative and water absorption stability) of obtained biocomposites were also clarified.

Authors: Tran Dzung Tien , Pham Duc Tinh , Nguyen Minh Tan , Tran Viet Ha
Published: March 2023

Data clustering tools can uncover new knowledge to be used in cancer diagnosis and treatment. In this study, we proposed a novel method to cluster records of a relation. First, we designed an algorithm that calculates the similarity between record pairs of the relation, and then this similarity measure was used to generate a network corresponding to the relation. Finally, we used a Network science technique to detect clusters of records from the network and extract insights from the clusters. Applying the method to mine a cancer-screening dataset at the Vietnam Central Cancer Hospital with over 177,000 records, we have discovered several new cancer laws in Viet Nam, which contribute to cancer detection and treatment support. It is disclosed from these cancer rules that some types of cancer run in certain family lines and living places in Viet Nam. Clustering a relation by Network science approach can be a good choice for mining large-scale relational data.

This paper presents an improving knowledge base and inference engine of a medical expert system for diagnosing depressive disorders. This medical expert system calls PORUL.DEP. PORUL.DEP’s knowledge base includes more than 850 positive rules. PORUL.DEP has been tested on more than 260 medical records of depressed patients. PORUL.DEP gives a correct diagnosis of more than 95% with light depressive disorder and without depressive disorder, but the remaining depressive disorders are not accurate. Average percent of more than 24 %. A new expert system, called STRESSDIAG, was developed on combining positive rules (for confirmation of conclusion) and negative rules (for exclusion of conclusion) for diagnosing depressive disorders. STRESSDIAG’s knowledge base consists of more than 850 positive rules of PORUL.DEP and more than 120 negative rules. Abelian group operation of Mycin is used to improve the inference engine based on fuzzy relations. STRESSDIAG gives the correct diagnosis of more than 76% with 4 depressive disorders types and without depressive disorders. Average percent of more than 82 %, up nearly 60% compared to PORUL.DEP.
Fabrication of highly permeable thin-film composite forward osmosis membrane using poly-l-lysine as an additive in polysulfone substrate
Authors: Pham Minh Tuan , Vo Anh Thu , Duong Tuan Manh , Dang Thi Thom , Do Van Manh
Published: March 2023

Forward osmosis (FO) has received considerable interest for water and energy-related applications in recent years. However, FO has not been commercialized yet because of a few reasons. The lack of a high-performance FO membrane is one of the important barriers. To overcome this issue, a novel high-performance thin-film composite (TFC) membrane was successfully fabricated via interfacial polymerization with poly-L-lysine incorporated polysulfone substrate (PSf). Compared to the pristine PSf substrate, the incorporation of lysine (ranging 1 – 15 wt.%) meaningfully alternates the substrates chemical structure, porosity, contact angle, and morphology leading to an enhancement of the lysine -TFC membranes performance. The results showed that the new substrates with higher porosity, more hydrophilic, and smaller in pore size after the introduction of L-lysine. The membrane achieved the highest FO water flux at 15% concentration of lysine and the maximum FO water flux was 35 L/m2.h (LMH) with a comparable specific salt flux (Js/Jw) of 0.002 g/L in the active layer facing the feed side (AL-FS) when 1M NaCl was applied as draw solution. The water flux was increased with increasing concentration of lysine. The addition of poly-L-Lysine in casting solution resulted in a more porous and hydrophilic support layer.
An Overview of Applying the Sustainability aspects and the Hazardous Waste Management in a Chemical industry in India
Authors: Kumar Yudhistra
Published: March 2023

The hazardous waste management in the chemical industry has been monitored from April 2021 to March 2022. All different kinds of hazardous waste were segregated by the concerned department and handed over to the environmental department. Different types of hazardous waste were handled,
stored, and disposed of as per the directions, which are provided in the combined consent of operations. We have followed the hazardous waste management rules 2016 for handling and disposing of hazardous waste. We have introduced a sustainable initiative, where the spent salt from the effluent
treatment plant, fly ash from the boiler and spent carbon from the process have been mixed in a suitable proportion in the form a utilizable waste, which is having higher calorific value has been sent in the cement industry in the regular basis. In this way, we are not only utilizing the hazardous
wastes but the various heavy metals such as Arsenic, Chromium, Mercury, Molybdenum, Nickel, Lead, Selenium, Zinc and Copper, which are present in the spent salt, fly ash and spent carbon is not let out into the environment. In case this toxic waste is not maintained properly, it would increase
the toxicity in the environment. Further, it will deteriorate the health of the employees and the contractors working in the working environment. We have taken the highest safety precautions while handling toxic hazardous waste so that we can protect the environment and occupants working in
the hazardous zone. We have studied the literature and identified the various twenty-four numbers habitat, which includes seventeen trees, three herbs, two shrubs, one grass and one bamboo are the recommended plantation species, which can be planted in the fly ash storage area. Planting such
type of species near to the fly ash storage area, will help us in absorbing the fly ash dust pollutants and the impacts of exposure to the pollutants of fly ash can be reduced in the occupational environment.

Published: March 2023

Cement is the strength-forming component of concrete. It has been a major building material for more than a century. However, its production is accountable for a considerable percentage of global CO2 emissions and is very energy-intensive. The Ordinary Portland Cement (OPC) production is a thermal process at around 1450 °C. This study shows that the reactivation of Hydrated Cement Powder (HCP) can be successful at a much lower temperature. Therefore, the possibility of using HCP to replace parts of OPC in concrete reduces the energy consumption and the CO2 emissions associated with OPC production. HCP, which may ultimately stem from recycled concrete, needs treatment to produce new concrete of the required mechanical strength. Using reactivated HCP in concrete, an optimum strength is achieved by heating the HCP in the range of 400–800 °C. Among other factors, the type of cement used influences the optimum heating temperature and attainable strength. This paper shows that 600 °C is an optimum heating temperature using the OPC type CEM I 52.5R. The crystalline phase transitions resulting from the thermal treatment were analyzed by X-ray diffraction (XRD), differential scanning calorimetry (DSC), and thermogravimetry (TG). The heat released during hydration was investigated, and scanning electron microscopy (SEM) displays the microstructure evolution. OPC can be partially replaced by thermally treated HCP in mortar, attaining similar mechanical strength values.
A Comparison of Living Standards Across the United States of America
Authors: Falcettoni Elena , Nygaard Vegard
Published: March 2023

We use an expected utility model to examine how living standards, or welfare, vary across the U.S. and how each state’s welfare has evolved over time. Our welfare measure accounts for cross-state variations in mortality, consumption, education, leisure, and inequality. We find that average living standards differ considerably across states. This is robust to allowing for endogenous interstate migration and to including housing in the model, and holds even when computing welfare conditional on education, gender, and race. Although states experienced heterogeneous welfare growth rates between 1999 and 2015 (ranging from 1.68 to 3.73 percent per year), there is no evidence of convergence in welfare levels, including during the sub-periods preceding and following the Great Recession. Whereas the level of real per-capita income is a good indicator of the level of welfare across states (correlation=0.75), the growth rate of real per-capita income is a poor proxy for the growth rate in welfare (correlation=0.42). Our welfare decomposition analysis can help identify what policies are likely to be most effective at increasing average living standards in the United States.
Systems Decision Process - A Systematic Approach to Support Decisions on Defense Acquisitions in the Development of Complex Weapon Systems
Authors: Guajardo Santana Rodrigo
Published: March 2023

Capability development is a complex process involving interactions between industrial suppliers of goods andservices with multiple government agencies often trying to balance competing objectives. The big dilemma is:how do governments acquire equipment, goods and services needed for their armed forces at a reasonable price,appropriate quality, and with a reasonable time frame? In this context, the development of new weapons systemsis a challenging process, which entails increasingly long development periods, the use of cutting-edgetechnologies in an environment of high uncertainty, requiring, for that reason, a decision-making supportprocess that adjusts to these specific requirements. Nowadays, decision-making is based on models used incertain decision-making instances, not considering the nature of the development programs above. Using asystems decision process (SDP) would allow a systemic and iterative, collaborative process and a value-baseddecision process that could be applied throughout the whole life cycle of this new weapons system.

Published: March 2023

The article deals with the issues of improving the efficiency of investment activities of small business sector entities through the participation of companies in investment projects of regional and municipal significance. An analysis of the advantages of small private businesses in the implementation of investment processes showed that small enterprises are able to help solve the most important social and economic problems of territorial entities due to natural mobility, innovative orientation, flexible tactics of behavior in the market, quick response to the needs of the consumer and partner sectors. But despite a number of obvious advantages of the small business sector, the article stated the fact that there is no desire for small businesses to participate in projects of regional and municipal significance and the predominance of strategic associations "big business – the state" in the Russian regions. In the course of the study, the reasons for the non-participation of small and medium-sized companies in projects of regional importance were attributed to: the disunity of interests of business and government structures, the unfavorable investment climate in the region of presence, the fictitious measures of state support for small businesses, the instability of the legislative system, the high tax and administrative burden on small and medium-sized enterprises, low level of mutual trust between government and business, instability of the political and economic situation in the country. A consistently negative factor for the development of investment activity in the SME sector within the framework of regional investment projects is the lack of guarantees and excessive regulatory requirements from the state. An analysis of the currently relevant results of sociological studies of federal services has shown that the most popular regional investment projects involve attracting investments in areas with the highest degree of distrust of entrepreneurs. A comprehensive assessment of the impact of natural barriers inherent in the economic activity of the small business sector and environmental factors led to the conclusion that it is expedient for small companies to participate in investment regional projects, subject to a complete transformation of the current relationship between business and government structures

The 28-spotted potato ladybird Henosepilachna vigintioctomaculata is an endemic pest of field crops in the Russian Far East. The phenetic structure research of this phytophage population can help to monitor the processes occurring in ecosystems, to study the resilience to pesticides and to resistant varieties, as well as to make a significant contribution to the study of the endemic fauna of the Far East. The elytra pattern to study the polymorphism and structure of a potato ladybird population was analyzed. The size and shape of spots, the intensity of color, the position of spots on the elytra, the presence of connected spots were taken into account. As the result, nine phenoforms were identified. The phenoform A2 prevailed (47.81%). The phenoforms A1 and A6 were also frequently discovered. The phenoform A9 had the most seldom occurrence (1.82%). It was stated that morphotypes differ by the linear dimension of elytra spots. The form A2 was characterized by the largest spots. The size of the patterns varied from (104.98 ± 0.071) to (297.01 ± 0.065)μ. The form A1 had the smallest spots.

In this paper, we analyzed the history of the genus Agarum. In Kamchatka, the species included in this genus are currently identified as A. clathratum and A. turneri. Currently existing genotypic systematic data, results of our own molecular-phylogenetic research, comparative analysis of descriptions, drawings and synonyms of Agarum species provided in references published by different authors, as well as investigation of the herbarium specimens from BIN RAS (LE) collected by members of the expedition by F.B. Lutke and M.N. Stanyukovich (1826–1829) revealed that, due to a misunderstanding of the volume and specific characteristics of A. clathratum and A. turneri, their species names are currently being used erroneously. Thus, in accordance with the International Code of the Nomenclature of Algae, Fungi and Plants, it is proposed by us to use the name А. clathratum for algae with a wide flat midrib and large perforations, whereas algae with a narrow convex midrib and small perforations should be indicated as A. pertusum. Our taxonomic changes were based on the investigation of herbarium specimens from the BIN RAS (LE) labeled by F.I. Ruprecht, and also on comparison of rDNA sequences obtained by us and those downloaded from the NBCI database. We also typified А. gmelinii, A. pertusum, А. turneri described by A.F. Postels and F.I. Ruprecht.

Background: Type 2 Diabetes (T2D) is associated with coronary microvascular dysfunction, which is thought to contribute to compromised diastolic function, ultimately culminating in heart failure with preserved ejection fraction (HFpEF). The molecular mechanisms remain incompletely understood, and no early diagnostics are available. We sought to gain insight into biomarkers and potential mechanisms of microvascular dysfunction in obese mice (db/db) and lean rats (Goto-Kakizaki) pre-clinical models of T2D-associated diastolic dysfunction. Methods: The microRNA (miRNA) content of circulating Extracellular Vesicles (EVs) was assessed in T2D models to identify biomarkers of coronary microvascular dysfunction/rarefaction. The potential source of circulating EV-encapsulated miRNAs was determined, and the mechanisms of induction and the function of candidate miRNAs were assessed in Endothelial Cells (ECs). Results: We found an increase in miR-30d-5p and miR-30e-5p in circulating EVs that coincided with indices of coronary microvascular EC dysfunction (i.e., markers of oxidative stress, DNA damage/senescence) and rarefaction, and preceded echocardiographic evidence of diastolic dysfunction. These miRNAs may serve as biomarkers of coronary microvascular dysfunction as they are upregulated in ECs of the left ventricle of the heart, but not other organs, in db/db mice. Furthermore, the miR-30 family is secreted in EVs from senescent ECs in culture, and ECs with senescent-like characteristics are present in the db/db heart. Assessment of miR-30 target pathways revealed a network of genes involved in fatty acid biosynthesis and metabolism. Over-expression of miR-30e in cultured ECs increased fatty acid β-oxidation and the production of reactive oxygen species and lipid peroxidation while inhibiting the miR-30 family decreased fatty acid β-oxidation. Additionally, miR-30e over-expression synergized with fatty acid exposure to down-regulate the expression of eNOS, a key regulator of microvascular and cardiomyocyte function. Finally, the knock-down of the miR-30 family in db/db mice decreased markers of oxidative stress and DNA damage/senescence in the microvascular endothelium. Conclusion: MiR-30d/e represents early biomarkers and potential therapeutic targets that are indicative of the development of diastolic dysfunction and may reflect altered EC fatty acid metabolism and microvascular dysfunction in the diabetic heart.

Published: March 2023

Introduction: Hepatitis B infection is a major public health problem worldwide, according to the WHO (World Health Organization) statistics in 2019 it affected 296 million people and over 6 million children under the age of five,It contributed to more than 820,000 death every year(1).According to its blood borne transmission nature of the virus, HBV (Hepatitis B virus) is very common in Khartoum and more likely to be endemic, a previous study which was conducted in Khartoum citizens, it prevailed that Hepatitis B Sero-prevalence among population varied from (47%) to (78%) which is very high and hepatitis B surface antigen prevalence ranging from (6.8%) in central Sudan to (26%) in southern Sudan(2). Objectives: The main aim of the study is to evaluate and assess the level of (KAP) toward (HBV) among (HCWs) in 60 Public and Private hospitals in Khartoum state, Sudan. Specific objectives are to estimate the proportion of immunized HCWs, to estimate the proportion of needle stick injuries and their relationships with the endemic status of HBV in Khartoum. Methods: A Cross sectional descriptive study will be conducted. The study will be conducted in the capital of Sudan,Khartoum state including 60 public and private hospitals that are well distributed among the tripartite metropolis capital of Sudan. From late January 2023 to late March 2023. population size is (21,576) Samle size will be calculated using the proportion formula of a cross sectional study (n = required sample size n = Z (α/2) 2 pq/d2). Size of population:(21,576), P value:(0.58), q(1-0.58)= (0.42) , (95%) confidence level and (2%) error margin. Here, n = required sample size, n = Z (α/2) 2 pp./d2, p = 0.58. This resulted in the required sample size of 2111 HCWs. A self administered questionnaire will be obtained from HCWs at the previously listed hospital. Data will be analysed using SPSS version 28.
The Effects of Online Production-Oriented Approach (POA) on Chinese Undergraduates’ English Speaking Competence Development During COVID-19 Pandemic Era
Authors: Asmawi Adelina , Sun Lixuan
Published: March 2023

The Covid-19 pandemic has expedited Online Teaching and Learning (OTL) following a sudden closure of academic institutions. Although within the past years, POA was fully developed and expanded in various projects that yielded fruitful college English learning results (Matsuda, 2017), recently, in the learning and practice of Oral English by Chinese undergraduates, there are distinct drawbacks and issues affecting language learning. This paper attempts to apply POA to Chinese undergraduates' oral English classes based on OTL during the covid-19 pandemic, specifically focusing on whether POA can increase the effectiveness of oral English learning for undergraduates. Data analysis of both the pre and post-tests revealed significant improvement in the experimental class and minimal improvement in the controlled class. Students' pronunciation, vocabulary, and fluency improved in the experimental group. It is implied that the POA application was effective in enhancing Chinese undergraduates' speaking skills. Some suggestions are put forth to enhance the application of online POA during the covid-19 pandemic era.
Language Learning Strategies and the Importance of Cultural Awareness in Indonesian Second Language Learners

Published: March 2023

This study examined the foreign/second-language learning strategies employed by eight Indonesian learners learning different languages (English, Chinese, and Arabic) and the role cultural awareness played in determining these strategies. The strategy inventory for language learning was used to record the participants’ learning strategies, and in-depth interviews were conducted to determine their cultural awareness acquisition when learning the foreign/second language and the effects this cultural awareness had on determining their language strategies. It was found that six main learning strategies were being used by the participants, and the interview data revealed that participants became more aware of the cultural aspects of their languages when reading authentic texts, communicating with native speakers, and attending their language courses. Cultural awareness was found to encourage participants to be selective learners when choosing learning materials and when using certain learning strategies. The results of this study broaden the insights of education practitioners and can guide foreign/second language teachers/lecturers in directing their students to use certain learning strategies.
Native Language Transfer in Vocabulary Acquisition: An Empirical Study From Connectionist Perspective
Authors: Zhang Li
Published: March 2023

Since the 1940s, the behaviorist paradigm, contrast analysis hypothesis and mentalist model have focused much attention on explaining the L1 - L2 relationship and how it works in second language acquisition. These studies support that different linguistic features of L1 and L2 would lead to language transfer. Nevertheless, there are still some questions being asked: How does native language transfer occur? What are the effective teaching methods to help L2 learners overcome the challenges of native language transfer? This study investigates native language transfer among Chinese university students in second language vocabulary acquisition. The results show that the connectionist model can explain the cognitive process of native language transfer through a dynamic approach, and adequate language input with timely grammar correction can enhance learning efficiency. The connectionist teaching method is effective in second language vocabulary acquisition.
The Role Played by Translation Within Cross-Cultural Communication: Case Study From EFL Teachers Based at Haql University College, Saudi Arabia
Authors: Othman Ahmed Khider
Published: March 2023

This study aims to enhance the cross-cultural communication skills of EFL learners and demonstrate the importance that translation has for cross-cultural forms of communication. A descriptive analytical method was followed in the study along with the distribution of a questionnaire to nineteen EFL teachers so that the necessary data could be collected. There was then statistical analysis of the data collected using the SPSS software 23. Many findings came out of the study, amongst the most important of which are that many skills are required in translation so that the original message can be conveyed into the language being targeted. Cross-cultural skills of communication of the EFL learners are improved in using translation. A number of cultural items that exist within a particular culture may not exist within another culture so there are some cultural items that are untranslatable. A vital role is played by translation in creating a general and universal culture. Without cultural universalities and similarities, people from different cultures have no way to communicate with one another and there will be an impossibility for translation to master the knowledge of differences and similarities between L2 and L1. The language accuracy of translators is developed through use of translation. This study recommends that the original message ought to be conveyed into the language being targeted by translation, and that communicators and learners of EFL ought to be able to communicate culturally through translation, and that translation ought to enable the so-called fifth language skill to be mastered by communicators.

Published: March 2023

As the L2 Motivational Self System (L2MSS) is premised on monolingualism, which ignores the cross-cutting properties of multilingual environments, this study investigates the English Learning Self and its structural characteristics of students in a junior high school in a minority-inhabited area of Guizhou Province, China. These ethnic minority students not only learn their native language (minority languages), but also learn Mandarin Chinese, through which they learn English as their third language, with features of low English proficiency, weak motivation to learn English, and low frequency of English use. Data were collected from 159 Han Chinese students and 274 ethnic minority students in the eighth grade of the junior high school. Structural equation modelling revealed that the Ideal English Self contains three factors: Ideal English Learner, Ideal English Career and Ideal English User, and the most significant Ideal English Self exhibited by the middle school students was Ideal English Learner; while the Ought-to English Self contains three factors: Meeting Other’s Expectation, Self’s Future Expectation and Self’s Present Demand, with Meeting Other’s Expectation marking contributed the most. Through comparative analysis, this study further found that there was no significant difference between local Han Chinese students and ethnic minority students in terms of English Learning Self.
