Authors: Vu Thu-Hien , Nguyen Phuong T. M. , Nguyen Tai
Published: May 2023

Obtaining high purity alkali niobate (KxNa1-xNbO3) thin films without secondary phase on metal coated traditional silicon (Si) substrates via sol-gel technique has remained great challenges until now. Herein, we report (K0.5Na0.5NbO3; KNN) thin films successfully deposited on Pt/Ti/SiO2/Si(100) substrates by a simply effective sol-gel process. A comprehensive and systematic investigation of processing conditions on the microstructures and electrical properties of spin-coated KNN films were presented. We have found that phase purity and microstructures of KNN films are strongly influenced by content of alkali excess and the annealing temperature. Thin films with an equal excess amount of 10% mol K and Na (KNN1) sintered at 650 oC show high crystallinity with a preferred (100)-orientation degree of 78%, and homogeneous and dense surface with columnar structure and large grain size up to 254 nm. The result of quantitative XPS analysis has proved that the composition of the film is close to the chemical stoichiometry. As a consequence, the obtained films exhibit a large dielectric constant of 775 and low dielectric loss of 0.020 in the wide frequency range from 1 kHz up to 10 MHz. Furthermore, well ferroelectric behavior of KNN films showed remnant polarization, Pr of 10.73 µC/cm2, coercive field Ec of 74.48 kV/cm and lowest leakage current density of 9.23×10–10 A/cm2 at E ≈ 5 kV/cm.
Being forced into an unsustainable and unethical working situation while caring for older people during the COVID-19 pandemic in Sweden
Authors: Lövenmark Annica , Hammar Lena Marmstål
Published: May 2023

Bakground: Worldwide, older people were more severely affected during the COVID-19 pandemic than others. In Sweden, those living in residential care facilities had the highest mortality rate, followed by those receiving home care services. The Swedish and international literature on the working environment for auxiliary nurses and nursing aides during the pandemic shows an increase in stress, anxiety, depression and post-traumatic stress syndromes. Care organisations were badly prepared to prevent the virus from spreading and to protect the staff from stress. In order to be better prepared for possible future pandemics, the health and well-being of the staff, the care of older people and the experiences of the staff both during and after a pandemic are important aspects to take into account. Therefore, this study aims to describe the residential care and home care service staff’s physical and psychosocial working experiences during and after the COVID-19 pandemic in Sweden.
Methodology: The data was collected through four focus groups interviews with 19 participants and analysed using qualitative content analysis.
Results: The result shows that the staff were forced into an unsustainable and unethical working situation by being portrayed as scapegoats by the older people’s relatives and the news media. In addition, they did not feel valued by people in general or by their own managers. The worsening working conditions that the pandemic contributed to resulted in a high degree of stress and risk of burnout, with staff members both wanting to and actually leaving their employment. Not only did the staff become innocent scapegoats in terms of the spread of the virus, after the pandemic they felt forgotten again and left to cope in an even worse situation than before.
Conclusions: According to the participants, the pandemic brought them, their working conditions and this part of the caring system to a tipping point, which the government and the media should no longer ignore. The pandemic revealed even more unsustainable and unethical working conditions for the staff in HCR and RCS than before the pandemic, including the vulnerability of the older people in their care.
The Superior Colliculus Projection Upon the Macaque Inferior Olive
Authors: May Paul J. , Warren Susan , Kojima Yoshiko
Published: May 2023

Saccade accommodation is a productive model for exploring the role of the cerebellum in behavioral plasticity. In this model, the target is moved during the saccade, gradually inducing a change in the saccade vector as the animal adapts. The climbing fiber pathway from the inferior olive provides a visual error signal generated by the superior colliculus that is believed to be crucial for cerebellar adaptation. However, the primate tecto-olivary pathway has only been explored using large injections of the central portion of the superior colliculus. To provide a more detailed picture, we have made injections of anterograde tracers into various regions of the macaque superior colliculus. As shown previously, large central injections primarily label a dense terminal field within the C subdivision at caudal end of the contralateral medial inferior olive. Several, previously unobserved, sites of sparse terminal labeling were noted: bilaterally in the dorsal cap of Kooy and ipsilaterally in C subdivision of the medial inferior olive. Small, physiologically directed, injections into the rostral, small saccade portion of the superior colliculus produced terminal fields in the same regions of the medial inferior olive, but with decreased density. Small injections of the caudal superior colliculus, where large amplitude gaze changes are encoded, again labeled a terminal field located in the same areas. The lack of a topographic pattern within the main tecto-olivary projection suggests that either the precise vector of the visual error is not transmitted to the vermis, or that encoding of this error is via non-topographic means.

This article deals with the development and implementation of a low-cost smart air quality monitoring device. The study aims to develop a simple, efficient, and cheap device dedicated to real-time monitoring of carbon dioxide (CO2) concentration and atmospheric parameters such as temperature (T) and relative humidity (RH). The realized device consists of sensors, data storage system, programmable card, and IoT wireless modules. It is designed for indoor and outdoor air quality monitoring. Wireless communication between realized device and control PC is ensured by the ZigBee protocol. This investigation is carried out to assess air quality considering the proliferation of pollutants and the modification of normal concentrations of atmospheric CO2 (400 ppm). Thus, the data processed are outdoor concentrations collected in November 2022 in some localities of the Adamawa Region, Cameroon. The average values of CO2 concentration measured in four subdivisions are 497.30 ± 11.32 ppm with a maximum and minimum values of [618 ~ 443] ppm in Ngaoundéré 1, 481.83 ± 14.90 ppm with [640 ~ 453] ppm in Ngaoundéré 2, 568.63 ± 25.03 ppm with [663 ~ 223] ppm in Martap and, 624.14 ± 3.96 ppm with [661 ~ 608] ppm in Minim. Martap and Minim locate one of the top bauxite deposits in the world. These values of CO2 higher than the normal atmospheric concentration indicate a moderate Air Quality Index (AQI) in these cities during the measurement period. The designed device is inexpensive, reliable, and appropriate for air quality monitoring.

Background
COVID-19, caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), has significantly impacted public health worldwide. However, the outcomes can be unfavourable for those living in areas where malaria is endemic and are affected by SARS-CoV-2. Therefore, this systematic review and meta-analysis aimed to determine the prevalence of coinfection between malaria and COVID-19.
Methods
A systematic review and meta-analysis of the literature were conducted, utilizing the most important databases in the field, such as PubMed, Scopus, Web of Science, Embase, and Google Scholar, up to April 9, 2023, using the search terms "Malaria" and "COVID-19". Three authors independently carried out the selection of studies, evaluation of their quality, and data extraction. The Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument was used to assess the quality of the studies. In addition, heterogeneity was evaluated using the statistical test I2, and the statistical analysis was performed using the R version 4.2.3 program.
Results
A total of 10227 studies were retrieved, of which 13 were included in the final meta-analysis. The pooled prevalence of coinfection between Malaria and COVID-19 was 45% (95% CI: 16, 76). Subgroup analysis was performed based on country, and the prevalence of coinfection between Malaria and COVID-19 was highest in China (100%, 95% CI: 88, 100) and lowest in the Democratic Republic of Congo (1%, 95% CI: 0, 2). Regarding the subgroup analysis to evaluate the prevalence of different types of Plasmodium spp. in COVID-19 patients, it was found that the combined prevalence of Plasmodium spp. was 53% (95% CI: 15%-88%; 478/1011 cases).
Conclusion
The current research revealed a 45% prevalence of coinfection between Malaria and COVID-19. However, additional future studies are necessary to evaluate the impact of COVID-19 in Malaria-endemic areas fully.
Trial registration
The protocol for this systematic review and meta-analysis was registered with PROSPERO under the registration number CRD42023410177.

Published: May 2023

The two-branch real-time semantic segmentation network can quickly acquire low-level details and high-level semantics. However, the large contextual gap between them results in adverse impact on their fusion, and limits the further improvement of real-time segmentation accuracy. This paper proposes a Tripartite Real-time Semantic Segmentation Network with Scene Commonality (TriSCNet) to address this problem. Firstly, we add a parallel Scene Commonality Branch (SCB) based on the current two-branch architecture to learn intrinsic common features in similar street scene images, such as the spatial location distribution of various objects and the internal connections between them at the semantic level. Further, with the guidance of commonality, we propose an External Branch Attention Module (EBAM) to enrich and enhance the feature information of traditional two branches. Lastly, we utilize an Alignment and Selective Fusion Module (ASFM) to correct the misaligned context in the semantic branch and highlight the essential spatial information in the detailed branch. Our proposed TriSCNet achieves an excellent trade-off between accuracy and speed, yielding 79.6% mIOU at 67.2 FPS on Cityscapes test set and 76.8% mIOU at 127.4 FPS on CamVid test set, respectively.

Background The present study conducted in the departments of Oueme and Plateau, aims to assess the presence of the dengue virus and its different serotypes in Ae. aegypti and Ae. albopictus, as well as the epidemic risk incurred by the populations.Method Collections of adult mosquitoes using human landing catches (HLC) were carried out in six communes, three of which (Porto-Novo, Adjarra and Avrankou) in the Oueme department, and the rest (Ifangni, Kétou and Pobè) in the Plateau department. Pools of ten Aedes mosquitoes were formed, and stored at − 80°C in RNA later. RT-PCR was used to detect dengue virus, and conventional PCR for the different setotypes. Inspection of water containers and collection of Aedes larvae were performed inside and around each house in order to calculate the stegomyan indices.Results In the six communes studied, the dengue virus was present both in Ae. Aegypti, and Ae. albopictus. Combined data of the two Aedes species at the communes level, revealed infection rates ranging from 80.00% (95% CI: 61.43–92.29) to 96.67% (95% CI: 82.78–99.92). In addition, the infection rates were similar for Aedes aegypti [88.19% (95% CI: 81.27–93.24)] and Aedes albopictus 86.79% [(95% CI: 74.66–94.52)]. The three virus serotypes detected in the pools of Aedes were: DENV-1, DENV-3 and DENV-4, with a high prevalence for the first two. Whatever the communes, the values of the stegomyan indices reached the threshold that indicates the existence of the risk of an arbovirosis epidemic.Conclusion The present study revealed that three serotypes (DENV-1, DENV-3 and DENV-4) of dengue virus circulate in Aedes aegypti and Aedes albopictus in the departments of Oueme and Plateau. Moreover, the risk of transmission of arboviruses was globally high and variable from commune to commune. These information are essential for informed decision-making in the preventive control of the disease.
Large-scale identification of lysine crotonylation reveals its potential role in oral squamous cell carcinoma
Authors: Yin Xiteng , Zhang Hongbo , Wei Zheng , Wang Yufeng , Han Shengwei , Zhou Meng , Xu Wenguang , Han Wei
Published: May 2023

Background
Lysine crotonylation, a newly identified type of posttranslational modification, has been implicated in the regulation of various biological processes. However, its role in oral squamous cell carcinoma (OSCC) remains unknown. The study aimed to reveal the global crotonylome in OSCC under hypoxic conditions and explore the potential underlying regulatory mechanism of crotonylation in OSCC.
Methods
Liquid-chromatography fractionation, affinity enrichment of crotonylated peptides and high-resolution mass spectrometry were used to detect differential crotonylation in CAL27 cells cultured under hypoxia. The obtained data were further analyzed through bioinformatics analysis to reveal the involved biological processes and pathways of the dysregulated crotonylated proteins. A site-mutated plasmid was used to investigate the effect of crotonylation on Heat Shock Protein 90 Alpha Family Class B Member 1 (HAP90AB1) function.
Results
The large-scale of crotonylome analysis revealed 1563 crotonylated modification sites on 605 proteins in CAL27 cells under hypoxia. Bioinformatics analysis showed that histone contonylation levels decreased while up-regulated crotonylated proteins were mainly concentrated in non-histone proteins. Notably, glycolysis-related proteins were prominently up-regulated among the identified crotonylated proteins, with HSP90AB1 having the most significant changes. Further experimental results confirmed that mutating lysine 265 of HSP90AB1 into a silent arginine weakened its function in promoting glycolysis.
Conclusion
Our study mapped the crotonylation modification of proteins under hypoxia in OSCC and uncovered the biological processes and pathways of the dysregulated crotonylated proteins. Crotonylation of HSP90AB1 in hypoxic conditions may promote the glycolysis regulation ability in OSCC, providing novel insights into the regulatory mechanism of crotonylation in OSCC under hypoxia and potential therapeutic targets for OSCC treatment.

Authors: Geng Zi-Han , Du Jun-Xian , Chen Yue-Da , Zhou Ping-Hong , Qin Wen-Zheng , Luo Yi-Hong
Published: May 2023

Background
Gastric cancer (GC) is one of the most common and lethal cancers worldwide. Apatinib, a preoperative neoadjuvant therapy, has limited efficacy in GC patients with high YY1 expression. YY1 is associated with poor prognosis, drug resistance and metastasis in GC, but its mechanisms are unclear.
Results
We observed that higher YY1 expression levels were associated with lower postoperative progression-free survival (PFS) and disease-specific survival (DSS) rates based on the TCGA analysis. Moreover, YY1 expression was found to be an independent indicator of DSS in GC patients. Additionally, YY1 expression was significantly higher in tumor tissues compared to adjacent normal tissues. Bioinformatics analysis revealed significant differentially expressed genes (DEGs), transcriptional targets, transcription factors, and co-expressed genes related to YY1. Through LASSO Cox analysis, we identified Transferrin as a potential key protein regulated by YY1, and its high expression was correlated with adverse DSS and PFS outcomes. Further analysis showed that YY1 regulated the activity of the p53 signaling pathway and ferroptosis in GC cells. The study also revealed that YY1 overexpression suppressed immune cell infiltration in GC tumors. Furthermore, the study demonstrated that YY1 overexpression inhibited GC cell ferroptosis and mediated Apatinib resistance through the p53 signaling pathway. IFN-a reverses Apatinib resistance and immune suppression in GC tissues.
Conclusions
Our findings suggest that YY1 plays a crucial role in GC progression and prognosis and may serve as a potential therapeutic target for improving patient outcomes.

In this paper, the formation of MoDTC-derived tribofilm and effects of its characteristics on friction reduction was evaluated. To consider a transition of the tribofilm during friction, in situ observation of the tribofilm was conducted by using a reflectance spectroscopy, and then thickness and composition of the tribofilm was calculated. As a result, the rough specimen (\({R}_{a}=12.7 \text{n}\text{m}\)) showed a smaller friction coefficient and kept a larger volume fraction of MoS2 compared with the smooth specimen (\({R}_{a}=2.6 \text{n}\text{m}\)). In addition, we estimated a transition of a shear strength of the tribofilm formed on both specimens by using the in situ observed composition and contact state. From the estimation, it was indicated that the shear strength of the tribofilm determined the friction properties, and the direct contact of the asperities which was notable to the rough specimen encouraged a generation of a low-shear tribofilm.

Published: May 2023

Mechanical forces govern many cellular functions, ranging from the embryonic development to the etiology of critical diseases. This fact attracts researchers in life science to study how cells sense and respond to extrinsic mechanical loading, and how cells generate mechanical force to regulate extracellular environment. To monitor the intracellular mechanical environment, FRET-based sensors are utilized for real-time measurements of cellular tension. However, transfection of the sensor gene shows low efficacy and is only effective for a short period. Transgenic mice expressing such sensors have been developed, but sensor fluorescence has not been measured successfully using conventional confocal microscopy. Therefore, methods for spatiotemporal measurement of cellular tension in vivo or ex vivo are still limited. We established reporter mouse lines expressing FRET-based actinin tension sensors consisting of EGFP as the donor and mCherry as the acceptor. Fluorescence from sensor fluorophores and FRET signal were visualized in aorta, tendon, heart, skin, diaphragm, and intestine from young and adult reporter mice with confocal microscopy. In addition, FRET tension sensor responded well to chemical stimuli to increase or decrease intracellular tension in isolated aortic smooth muscle cells. Furthermore, application of macroscopic mechanical stretch induced tension-induced changes in FRET signals in the aorta and tail tendon fascicles, as well as aortic smooth muscle cells isolated from these mice. The pattern of FRET changes was distinctive and dependent on tissue type, reflecting differences in extracellular matrix structures and functional requirements for cells residing in these load-bearing tissues. Aortic smooth muscle cells exhibit lower sensitivity to tensile strain in situ than in an isolated state, proving for the first time that change in intracellular tension was smaller in situ than in vitro at the same macroscopic strain level. This mouse strain will enable novel types of mechanobiological and biomechanical investigations of cell functions in important physiological events.

SOMATIC METAPHORS OF NIKITA KHRUSHCHEV’S SECRET SPEECH IN TRANSLATION
Authors: Carter Elena V. ,   St. Petersburg Mining University
Published: May 2023

It is generally recognized that a linguocultural analysis makes it possible to identify equivalents in the phraseology of different languages, to indicate what is common and unique for the languages analyzed and to reveal various kinds of translation difficulties, in particular, the rendition of phraseological units with somatic components. As the previous research shows, this issue has not been well-examined in relation to the political discourse yet. Thereby, the present study makes a contribution to the field of phraseology as well as to the area of translation. The article is devoted to the comparative analysis of the Russian phraseologisms with the somatic elements which were employed by N. S. Khrushchev in his report “On the Cult of Personality and Its Consequences” at the closed session of the 20th Communist Congress on February 25, 1956, and the ways of their translation into English. The paper describes the connotations that arise, while interpreting the paremia images in the space of historical and cultural knowledge, identifies cultural layers in the semantics of the idioms, allowing to highlight the commonalities or differences of the meanings that are characteristic for the languages in question. The contrastive analysis of Russian and English somatic metaphors reveals similarities in the processes and ways of phrase formation of a number of idioms which enable translators to use appropriate equivalents. Of particular interest are the cases when there is a lexical substitution of the Russian somatism for a different English phrase-lexeme which, in turn, creates certain challenges when translating such idioms.

The study of the specifics of the manifestation of national and cultural codes in the literatures of the peoples of Russia, in particular, in the work of modern Tatar poets, is of great scientific and practical interest for researchers. The article presents the result of a systematic and complex analysis of the work of modern Tatar poets Renat Haris (1941) and Ravil Fayzullin (1943) in the aspect of revealing the originality of the artistic embodiment of national cultural codes. The object of the research is the poems of Renat Haris and Ravil Fayzullin. The subject of the research is the artistic embodiment of national and cultural codes in the works of Renat Haris and Ravil Fayzullin through the analysis of symbolic images, universals, allusions and genres, features of color and light images. The leading research method is a systematic approach, which allows applying historical-functional, historicalgenetic, comparative-typological and historical-functional methods to the study of the work of modern Tatar poets. The article is dominated by an interdisciplinary approach that makes it possible to adequately determine the current state of Tatar literature and literary criticism in the context of the cultures of the peoples of Russia, near and far abroad. The Tatar national picture of the world also includes musical images such as kurai, accordion, etc., in relation to Tatar poetry and music, the concept of “mon” is often used, which is difficult to translate into other languages, in this regard, an analysis of the works of Renat Haris and Ravil Fayzullin allows us to reveal the problem of “untranslatable” in Tatar literature. The work of the studied poets reflects the Tatar national picture of the world, reveals its main components: the image of the motherland and native land, concern for the fate of the Tatar language, literature and culture in the era of globalization. Poets dedicate their poems to the description of national holidays (Sabantuy), traditional symbols of the Tatar people (images of a white leopard (ak leopard), horse, white towel, etc.), spiritual and moral values and the history of the Tatar people are described in their poems.

Published: May 2023

The article studies semiotic mechanisms of organizing Internet memes on coronavirus (COVID-19) as polycode texts reflecting the socio-cultural phenomenon significant for an indefinite period. It also examines relevant evaluative meanings of COVID-19 arising through the interaction of image and text in polycode units. Systemic functional multimodal discourse analysis serves as the research methodology and provides the framework for linguistic, cognitive and pragmatic aspects of the study. In line with the approach, a comprehensive interpretation of a communication act incorporating text analysis along with situational and cultural reflection, the inductive method and its main research procedures (observation, analysis and comparison) are applied to specify the COVID-19 discourse in Internet memes. The analysis of the system-functional peculiarities of coronavirus-related Internet memes has specified textual means of designing a communicative intention in polycode units, semiotic elements of pragmatic impact, as well as a multimodal perspective of interpreting the COVID-19 discourse through the interaction of verbal and visual references. The results show that COVID-19 memes convey condition-, interaction- and event-oriented evaluative meanings. The study revealed that the semiotic tools of different origin and precedence degree enable verbal-visual interaction to convey the sense of kinship and shared experience. Along with the disturbing meanings of apprehension and danger, the Internet memes noticeably express social unity and confidence in overcoming the challenges. The meanings are reinforced by the images of significant cultural value in the Russian community.

Published: May 2023

The paper regards catharsis therapeutic application as a theme of the 17th century English drama: a case study of Brome’s play “The Antipodes” (1637– 1638), never being in focus of Russian literary criticism. Catharsis is a central concept of drama especially in its scenic presentation. The resemblance of personal experiences to those in a play can provoke strong cathartic emotions, causing spectator’s purification and mental balance. The 20th century psychology used this effect as a “psychodrama” method for treating patients with mental disorders. Its essence is in transforming patients into actors of a dramatic piece reminding them their traumas, the emotions resulted proceed with cathartic cleansing of the painful symptoms. The paper discusses in detail the first use of the “psychodrama” method in the 17th-century English comedy “The Antipodes”. The play’s theme is the characters’ mental disorder featured with despondency and insanity healed by doctor Huball’s method of making the unsuspecting patients act in a performance (“inner play”) of an artificially created “antipodean” world of disorder similar to their overturned consciousness. The patients’ rejection of the “antipodean” world brings in strong cathartic emotions causing the characters’ mental health. The play’s analysis shows that the author exceeds the limits of the avant-garde catharsis therapy theme. The play passes his concern about the disease of the English society facing serious upheavals. It aims at bringing all his spectators in catharsis in order to heal the English world’s disease and let common sense triumph over the existing disorder and madness.

The article contains analysis of escape clause stipulated by Art. 1211-9 of the Civil Code of the Russian Federation and allowing the court, when choosing applicable law for contract, in exceptional cases to reject the conflict of laws rule prescribed by law in favor of the law which is obviously more connected to contract. The author conducts a case by case analysis of Russian judicial practice, including judicial acts in which application of escape clause is extensively substantiated and those in which such application is based on the sole counter-directed link of contract or is barely substantiated. Moreover, the examples of disaffirmation of judicial acts which have been based on unjustified application of Art. 1211-9 of the Civil Code of the Russian Federation as well as cases of illustrative utilization of the indicated provision are under analysis. The author pays special attention to the standard (criteria) of the closest connection principle applied under the auspices of escape clause for contractual legal relations of international character. The author stands for thesis that the court recourse to escape clause of Art. 1211-9 of the Civil Code of the Russian Federation as an exceptional case requires ‘comparative weighing’ of differently directed links of the exact contract culminating in clear conclusion on sum of significant links to the law of other country in contrast to insignificant link to the law of country indicated by conflict of laws rule. At the same time, indicators (criteria) of the closest connection, stemming from unity of its contents even for different functions within conflict of laws framework, should embrace not only territorial contacts of the exact contractual legal relation but also important substantive law considerations (including lex validates acknowledged by the Supreme Court of the Russian Federation).
A new “catch 22”: “Protective measures”, “preventive measures” and “sports sanctions” versus Russian athletes

After the announcement of a Russian special military operation, the International Olympic Committee (IOC) on February 28, 2022 offered its Recommendations to the Olympic Movement (international sports federations and other global sports’ organizers) on the participation of subjects of Russian sports. The IOC recommended that Russian athletes should not be allowed to participate in international competitions unless Russian participants act as neutral athletes. Since that date, international sports federations have imposed and continue to impose multidirectional negative measures against Russian athletes. Despite the formally non-mandatory status of Recommendations, the federations have chosen Russian athletes’ suspension and not “neutral status”, with rare exceptions (and the nuances of the decisions): the International Judo Federation (IJF), the International Tennis Federation (ITF), the International Automobile Federation (FIA), the International Cycling Union (ICU). Unfortunately, suspensions of Russian athletes have become a “routine” practice of global sports in 2022. The speed of making suspension-decisions identical to the IOC Recommendations raised a well-founded question about the existence of legal grounds for suspensions in the regulation of international federations. This research is focused on the types and content of “measures” (“protective”, “preventive”, “sports sanctions”) against Russian athletes, including the IOC proposed “protective” doctrine. As a result, at least three main points were identified. First, the names “protective” and “preventive” are artificial, and all measures are identical in content. Second, at the time the measures were adopted, the statutes of the sports federations did not explicitly provide for either “protective measures” or “preventive measures”. Thirdly, the use of “sports sanctions” as “measures” is not based on the statutes and constitutions of international sports federations.

In the modern era, social transformations contribute to the dynamic development of basic legal frameworks governing public relations. Consequently, the lawmaking process is facing a certain crisis due to the rising legislative inflation and a gap between the pace of social change and lawmaking mechanisms. In these circumstances, improving lawmaking activities should be based on doctrinal developments, including those concerning lawmaking quality and efficiency. The article uses constructivism methodology to illustrate the inextricable connection between the legal process and law enforcement, which is seen as the first stage in the process of shaping the legal reality. The authors analyze how domestic legal thinking has evolved in relation to the efficiency and quality of lawmaking. A list of the criteria and parameters proved by Soviet and post-Soviet scientists was compiled. It is shown that lawmaking activity efficiency and quality are dialectically related. It is justified to consider the social determinants that affect lawmaking efficiency. Accordingly, it is concluded that the efficiency of legal norms should be measured by what impact their application has had on society, in what extent they have met the goals of social management at the given stage of social development. The authors propose three levels of measuring the efficiency of legal norms in modern society: formal-legal, axiological and general social. The value of legal monitoring is highlighted in assessing the quality of lawmaking and determining the extent to which legal norms are efficient.

A partir de la Literatura revisada, se detecta la inexistencia de estudios sobre dominio lector en el contexto regional del Norte de Chile, por lo que se consideró necesario estudiar las pautas de lectura y el aporte que realizan las familias en el nivel primario de educación. De acuerdo con esto, se buscó establecer la relación entre variables que permitieran determinar cómo se relacionan los estilos parentales y prácticas familiares asociadas a la lectura y el dominio lector de los hijos(as). El estudio se situó bajo el paradigma cuantitativo. Para la información, se realizó un análisis descriptivo, correlación de Pearson y Análisis de regresión lineal simple de la data recogida en el trabajo de investigación de Canivilo et al. (2018) en el cual se aplicó una encuesta sociodemográfica, la prueba de dominio lector de la Fundación Arauco y el Parenting Styles and Dimensions Questionnaire. Los resultados muestran una correlación entre la calidad lectora, velocidad lectora y el estilo parental, además de prácticas familiares que favorecen la habilidad lectora. A partir de la discusión, es visible que el estilo parental autoritario y algunas prácticas familiares de lectura predicen la velocidad y calidad lectora del hijo(a).

Lithium recovery from brine is recently attracting significant attention due to increasing industrial demand for energy storage, such as batteries. The lithium recovery from lithium brine was investigated using hydrogen manganese oxide adsorbent. The hydrogen manganese oxide adsorbent HMn2O4 (HMO) is derived from the spinel lithium manganese oxide (LMO), which is synthesized from LiOH and MnO2 precursor through the reflux method. The synthesized adsorbent was characterized using Scanning Electron Microscopy to identify its physical characteristics and its surface morphology. The adsorption capacity toward lithium solution was performed through an ion exchange process, and the adsorption values were determined using Atomic Absorption Spectroscopy (AAS). The synthesized HMO has a high lithium adsorption capacity for lithium-ion, which is 23 mg/g, and 10 mg/g for desorption. The optimum uptake capacity of HMn2O4 is 44% of the initial values (52 ppm) after 120 minutes of contact time. The synthesized hydrogen manganese oxide adsorbent has a potential industrial lithium recovery for large-scale application.

This study aimed to observe the influence of weather parameters (irradiation, ambient temperature, PV module temperature, wind speed, and direction). Performance evaluation of rooftop PV systems is carried out according to IEC 61724-1:2017. The parameters measured are solar irradiance using a pyranometer, the surface temperature of the PV module using a temperature sensor, ambient temperature, wind speed, and direction using the Smart Weather Sensor Lufft type WS500-UMB. The analysis was performed under three different weather conditions: cloudy, rainy, and sunny skies. In rainy conditions, the highest efficiency of the PV array is 16.1% – 16.69%, because the environmental temperature and the temperature of the PV module when it rains is the lowest compared to sunny and cloudy conditions. In sunny skies, the highest inverter efficiency is obtained, around 97.9 – 98.84%, this is due to very high solar irradiation (more than 1000 W/m²), so the inverter works more optimally than in rainy and cloudy conditions. The highest average wind speed is obtained in sunny conditions, which is 3.28 m/s with the same wind direction, namely the West-Northwest, but the influence of the wind is not significant to provide a cooling effect to the rooftop PV.
