Published: April 2024

''Society 5.0'' seeks to enhance well-being by integrating the Internet of Things to connect people, objects, and environments, which aims to gather and utilize data from the physical world in cyberspace fostering new values and knowledge sharing. It extends the concept of Cyber-Physical Systems by focusing on human-centric sensing and AI-driven analysis to capture and understand the nuances of human behaviors and their environments. To realize the concept, intelligent environments, focusing on creating sensor-enhanced spaces capable of recognizing and interpreting human behaviors and needs, are essential. To explore how we realize the intelligent environment, this paper highlights the current technologies and applications of human sensing and tracking that enables such intelligent environments.Specifically, it introduces the development and application of LiDAR-based human sensing and tracking technologies, including the Hitonavi and Hitonavi-µ systems, designed for multi-person tracking in extensive areas and for enabling person detection and activity recognition on edge devices, respectively. Moreover, the services and applications of the introduced methodologies to smart buildings, shopping malls, and elderly care have been explained to showcase their potential to enhance safety, convenience, and understanding of human behavior within intelligent environment. Throughout this paper, we present our vision for creating a reliable intelligent environment, which is fundamentally supported by sophisticated human sensing technologies.

Published: April 2024

Options for atrioventricular (AV) valve replacement in small pediatric patients are very limited. The Melody valve has shown reasonable short-term outcomes. This study was aimed at identifying predictors of valve failure following AV valve replacement with a Melody valve at a single center. 26 patients underwent 37 AV valve replacements with 31/37 (84%) of valves placed in the systemic AV valve position. Median age at procedure was 17 mos (IQR 4–33) and weight was 8.5 kg (IQR 6.25–12.85). Median balloon size for valve implant was 20 mm (IQR 18–22). Repeat intervention occurred in 21 cases (57%) with repeat surgery in all but one. Median freedom from re-intervention was 31 months; 19% were free from re-intervention at 60 months. Age < 12 mos, weight < 10 kg and BSA < 0.4 m2 were all significant risk factors for early valve failure (p = 0.003, P 0.017, P 0.025 respectively). Valve longevity was greatest with balloon inflation to diameter 1.20–1.35 times the patient’s expected annular diameter (Z0), relative to both smaller or larger balloons (p = 0.038). In patients less than 12 mos of age, patients with single ventricle physiology had an increased risk of early valve failure (p = 0.004).

Authors: Shikali Joyce , Muneja Paul Samwel , Ally Mohamed Kasim
Published: April 2024

The study examined access to library information resources by university students during the outbreak of the COVID-19 pandemic in 2020. Specifically, the study sought to identify the measures adopted by academic libraries to ensure the smooth delivery of library information resources to patrons, particularly students, identify technological tools that were employed by libraries to facilitate access to library information resources. Not only that but also, the study investigated the challenges faced by students in accessing library information resources. A systematic literature review approach following PRISMA guidelines was employed to investigate the findings of the relevant literature on the subject. The keyword search strategy was employed to search for relevant literature from four scholarly databases Scopus, Emerald, Research4life and Google Scholar. The relevant 23 studies were included fulfilling the set inclusion criteria. The presentation of the findings was arranged in a tabular form to provide a summary of each article to facilitate easy analysis and synthesis of results. The findings of this study revealed that the majority of the reviewed studies indicate that, during the COVID-19 pandemic many academic libraries in Africa adopted different approaches to facilitate access to library information resources by university students including expanding access to electronic resources off- campus, virtual reference services, circulation and lending services. To support access to different library services and information resources academic libraries in Africa used various digital technological tools like social media, library websites, email and video conferencing. Moreover, the study revealed that limited access to internet services and ICT devices, inadequate electronic library collection and inadequate digital and information literacy were the major challenges faced by many university students in accessing library resources during the pandemic. This study recommends investment in ICT infrastructures and expanding electronic resource collections which are vital resources in the digital era.
Ectopic Breast Cancer in the Axilla after Bilateral Breast Cancer Surgery
Authors: Ishige Hiroyuki
Published: April 2024

Background
Ectopic breast cancer (EBC) is a rare disease, and cases of its occurrence in the axilla following surgery for bilateral breast cancer have not been previously reported.
Case Presentation:
We report the case of a 69-year-old woman who developed EBC cancer in the left axilla as a third metachronous primary cancer after bilateral breast cancer.
Conclusion
When a mass is observed in the axilla after breast cancer surgery, it is crucial to consider not only the possibility of lymph node metastasis but also the differential diagnosis of axillary EBC for appropriate diagnosis and treatment. If the mass is located just beneath the skin and on the outer side of the axilla, suspicion of EBC is warranted. As they do with pectoral breast cancer, the ultrasound findings of EBC vary according to the tissue structure.
Directing cancer cell fate with wireless barium titanate@PEDOT nanoparticles to control bioelectricity

Published: April 2024

Cancer cells exhibit unique bioelectrical properties, yet therapeutic strategies exploiting these are still lacking. Herein, we merge a nanobioelectronic system comprising of a barium titanate nanoparticle core and a poly(3,4-ethylenedioxythiophene) shell (BTO@PEDOT NPs) with cancer cells to modulate bioelectricity. We hypothesize that the BTO@PEDOT NPs act as a nanoantenna, transducing a mechanical input provided by external ultrasound (US) stimulation into an electrical output, capable of interfering with the bioelectronic circuitry of the human breast cancer cell lines, MCF-7 and MDA-MB-231. Upon US stimulation the viability of MCF-7 and MDA-MB-231 treated with 200 µg mL-1 BTO@PEDOT NPs reduced significantly to 31% and 24%, respectively, while healthy human mammary fibroblasts were unaffected by the treatment (94% viability). The treatment increased ROS levels and intracellular Ca2+ concentrations, thus promoting apoptosis. These findings underscore the potential of nanobioelectronic systems as an emerging and promising strategy for cancer intervention with no impact on healthy cells.
Effects of Photoperiod Treatments on Stock Plants and Cutting Rooting of Three Cultivars of Ornamental Perennials
Authors: Conner Koski Ronda D. , Klett James E. , Burcham Daniel
Published: April 2024

Many species of herbaceous perennials now have numerous cultivars, with growth habits and flower colors unique to each cultivar. Vegetative propagation is required so that resulting plants are genetically identical to the parent plant. Although many cultivars are selected for precocious and vigorous flowering, it is often difficult to collect adequate vegetative cuttings from such cultivars for commercial production because juvenile (vegetative) growth is preferred for high-quality cuttings. Cuttings that are reproductive (with flower buds or flowers) can have reduced or delayed rooting and increased occurrences of fungal pathogens (especially Botrytis species), resulting in lack of crop uniformity. We sought to answer the question, can growing stock plants of herbaceous perennials under defined photoperiods extend the length of the vegetative period and enhance the rooting of cuttings harvested from these stock plants? In this study, stock plants of ‘P009S’ twinspur (Diascia integerrima), ‘Furman's Red’ sage (Salvia greggii), and ‘Wild Thing’ sage (Salvia greggii) were grown under ambient, 12-hour light, 10-hour light, and 8-hour light to determine if a particular photoperiod could be used to suppress reproductive growth by promoting vegetative growth, thereby enhancing cutting rooting success. Effects of photoperiod treatments varied among the plant cultivars studied. Plants grown under 8-hour photoperiod had longer duration of vegetative growth, smaller growth rates, and lower dry weights when compared with plants grown under 12-hour or 10-hour photoperiod. Plants grown under 12-hour photoperiod had shorter duration of vegetative growth, larger growth rates, and higher dry weights when compared with plants grown under 10-hour and 8-hour photoperiods. The probability of rooting of cuttings harvested from stock plants of ‘P009S’ twinspur, ‘Furman’s Red’ sage, and ‘Wild Thing’ sage grown under 12-hour and 10-hour photoperiods was greater when compared with cuttings harvested from stock plants grown under 8 h photoperiod.

Published: April 2024

Nepheline is one of the main rock-forming minerals of the rocks of the Khibiny alkaline massif. Nepheline composition changes depending on the crystallization temperature, which makes it an indicator of rock formation conditions. In addition, nepheline is one of the main concentrators of hydrocarbon gases. The study of nepheline from different rocks of the Khibiny massif by local IR spectroscopy with Fourier transformation (micro-FTIR) has revealed the presence of water and acetylene in its structure. The water content estimated according to the method of statistical quantitative determination of water in nominally anhydrous minerals varies in the range from 0 to 0.78 wt.%. The highest water content has been observed in high-temperature nepheline of early formations (foyaite of the central and outer parts of the massif), and the lowest – in relatively low-temperature nepheline of later rocks of the Main Ring Fault (urtite, apatite-nepheline rock and poikilitic (kalsilite)-nepheline syenite – rischorrite). The study reveals that water enters the structure of nepheline in the form of H2O molecules that occupy vacancies in the potassium sites. The water content in nepheline is controlled by the number of vacancies in its structure. The presence of acetylene has been determined on a qualitative level. Additional studies are required to assess its quantitative content.

A cloud-based infrastructure to deploy supervisory forecast models for predictive coagulant dosing control
Authors: Nair Abhilash , Yavorska Viktoria , Hykkerud Aleksander , Ratnaweera Harsha
Published: April 2024

Advanced optimal dosing control based on multiple online sensor data is operational in several treatment facilities in Norway. The benefits of the dosing control system in maintaining stable phosphate/solids removal and saving coagulant usage are documented in the literature. The dosing algorithm is currently implemented in a programmable logic controller (PLC) connected to the treatment plant's Supervisory Control and Data Acquisition System (SCADA) system. The PLC receives online sensor data from the plant's SCADA, calculates the optimal dosing values, and transmits optimal dosage values back to the SCADA system. The dosing algorithm is frequently updated to keep in sync with the process and equipment upgrades of the treatment plant and advances in control algorithm schemes. The upgrades include new regulatory feedback loops structural changes to the dose equation, and the addition of conditional setpoints. Each maintenance and upgrade routine entails operational downtime where the dosing algorithm is set to a sub-optimal flow-proportional dose. This paper presents a non-intrusive Internet of Things (IoT) infrastructure to implement a predictive/forecast component to an existing dosing control algorithm. The benefits of the new cloud-based system in improving nutrient removal, increasing operational flexibility, and reducing maintenance downtime are presented in this work.

Published: April 2024

Mitral defects are the most common acquired heart disturbances. The only radical treatment for severe valve stenosis or its insufficiency is surgical correction of the defects. The main challenge of implanting a mechanical mitral prosthesis is associated to its thrombosis complication that demands repeated surgical intervention on re-replacement of the mitral prosthesis. Herein, a clinical case of patient P. (58 years old) is presented, who was admitted to the Federal Center for Cardiovascular Surgery (Penza, Russia) with thrombosis of the mitral valve prosthesis and its dysfunction. The patient has already been undergone repeated surgery to replace the mitral valve. The purpose of the clinical case description is to demonstrate the using of open mitral valve replacement method based on the valve-in-valve technique with a transcatheter balloon-expandable prosthesis, its efficacy and safety.The considered method of treatment can simplify the main stage of the surgical intervention; reduce the time of artificial circulation and aortic clamping as well as the number of intraoperative complications. This type of surgical treatment can be considered as an option for re-prosthesis in patients at high surgical risk who are indicated for re-intervention due to impaired function of previously implanted heart valve prosthesis. A clinical case attests the possibility, efficacy and safety of using a balloon-expandable prosthesis for mitral valve replacement with the valve-in-valve technique upon repeated surgical interventions.

Introduction: The reliability of statistical analysis and its results is becoming a focal point in scientific discourse, overshadowing concerns about statistical significance. Systematic reviews and meta-analyses are characterized by a range of serious statistical and methodological limitations, including insufficient statistical power, clinical and statistical heterogeneity, systematic errors, potential low quality of included examinations, limited data availability, and publication bias. In this context, “Trial Sequential Analysis” (TSA) emerges as a promising methodological tool used in combination with meta-analyses to enhance the precision and robustness of scientific conclusions. Objective: The study is aimed to demonstrating potential scenarios for the using TSA and its role in improving the reliability of scientific conclusions through meta-analyses published in Russian journals on anesthesiology-resuscitation, as well as the authors’ own meta-analyses.Methods: This study is a systematic review without a detailed description of the case studies. The search for meta-analyses was conducted using the keywords “meta-analysis”, “mortality”, “delirium”, “sedation”. Two researchers independently reviewed the titles and abstracts of the selected meta-analyses and extracted data. TSA was conducted for all meta-analyses using “TSA software” (Copenhagen, Denmark). Results: 6 studies were considered, and 7 TSA evaluations were performed. Six out of the seven TSA evaluations confirmed the conclusions of the pertinent meta-analyses. In one TSA, the cumulative Z-line did not reach the required sample size, highlighting the need for additional studies to definitively confirm the result. In two TSAs, the sample size in the meta-analysis was insufficient to draw definitive conclusions. The application of TSA in these cases could provide more substantiated and cautious conclusions.Conclusion: This study explores various scenarios for the application of TSA in meta-analyses published in both Russian and international journals in the fields of anesthesiology and resuscitation. The significance of TSA for enhancing the validity and clinical relevance of research findings was substantiated.

A Baía Babitonga é considerada área prioritária para conservação e uso sustentável, de acordo com a Portaria MMA n.º 9, de janeiro de 2007, pois é local de reprodução, alimentação e crescimento de espécies protegidas e espécies ameaçadas de extinção e abriga uma das maiores florestas remanescentes de manguezais da América do Sul. Este trabalho teve como objetivo realizar um estudo de reconstrução ambiental do Canal do Linguado, buscando gerar subsídios para tomada de decisão pelos órgãos competentes quanto à abertura do Canal do Linguado. Foram analisados os níveis de arsênio (As), cádmio (Cd), cromo (Cr), cobre (Cu), níquel (Ni), chumbo (Pb) e zinco (Zn) em conjunto com a geocronologia atual, obtida a partir das atividades dos radionuclídeos 210Pb, utilizando o modelo CRS (Constant Rate of Supply). Os resultados obtidos nos quatro testemunhos analisados mostraram que as variações de metais nos perfis muito provavelmente ocorreram em consequência da ação de fechamento do Canal do Linguado na década de 1930, que modificou a hidrodinâmica de sedimentação da região. Conclui-se que as concentrações de metais encontradas estão abaixo dos valores nível 1 definidos pela Resolução Conama 454/2012. Os resultados fornecem um diagnóstico da qualidade do sedimento atual, possibilitando uma melhor compreensão do histórico ambiental da Baía Babitonga, a fim de balizar as próximas ações nesse ecossistema.

No curso do rio, o percurso da cidade: reflexões sobre Balneário Camboriú (SC) por meio da análise da paisagem da foz do Rio Camboriú
Authors: De Souza Isabella
Published: April 2024

Nas últimas décadas, a cidade de Balneário Camboriú (SC) tem passado por profundas modificações em seu espaço. Essas transformações marcaram, especialmente, um significativo local para a história do município: a foz do Rio Camboriú. Foi ali, nas margens desse rio, que ocorreu a ocupação inicial da cidade em meados do século XIX. Com o passar dos anos, diferentes edificações foram se instalando em suas margens, modificando as relações sociais ali estabelecidas. Pensando nisso, o presente artigo propõe uma leitura da paisagem da foz do Rio Camboriú como um palimpsesto para compreender aspectos relacionados à história da cidade, assim como as dinâmicas que têm se engendrado na cidade contemporânea. Ao analisar os elementos que compõem tal paisagem atualmente, foi possível identificar dois processos que ali ocorrem: por um lado, verifica-se a privatização de suas margens, sendo acessado e/ou visualizado sobretudo por meio de equipamentos turísticos, edifícios residenciais e marinas. Por outro lado, há um esforço, por parte do poder público municipal, em delimitar as margens do rio como local da tradição e da cultura popular, em torno da Igreja Santo Amaro, um dos únicos bens tombados da cidade. Assim, as diversas formas urbanas que ocupam suas margens atualmente possibilitam um debate sobre as práticas e usos do passado, como também especulações sobre as transformações que estão ocorrendo no espaço da cidade.

Comparison of Self-Tracking Health Practices, eHealth Literacy, and Subjective Well-Being Between College Students With and Without Disabilities: Cross-Sectional Survey
Authors: Choi Soyoung
Published: April 2024

Background

College students with disabilities need to transition from pediatric-centered care to adult care. However, they may become overwhelmed by multiple responsibilities, such as academic activities, peer relationships, career preparation, job seeking, independent living, as well as managing their health and promoting healthy behaviors.

Objective

As the use of smartphones and wearable devices for collecting personal health data becomes popular, this study aimed to compare the characteristics of self-tracking health practices between college students with disabilities and their counterparts. In addition, this study examined the relationships between disability status, self-tracking health practices, eHealth literacy, and subjective well-being among college students.

Methods

The web-based questionnaire was designed using Qualtrics for the cross-sectional online survey. The survey data were collected from February 2023 to April 2023 and included responses from 702 participants.

Results

More than 80% (563/702, 80.2%) of the respondents participated voluntarily in self-tracking health practices. College students with disabilities (n=83) showed significantly lower levels of eHealth literacy and subjective well-being compared with college students without disabilities (n=619). The group with disabilities reported significantly lower satisfaction (t411=–5.97, P<.001) and perceived efficacy (t411=–4.85, P<.001) when using smartphone health apps and wearable devices. Finally, the study identified a significant correlation between subjective well-being in college students and disability status (β=3.81, P<.001), self-tracking health practices (β=2.22, P=.03), and eHealth literacy (β=24.29, P<.001).

Conclusions

Given the significant relationships among disability status, self-tracking health practices, eHealth literacy, and subjective well-being in college students, it is recommended to examine their ability to leverage digital technology for self-care. Offering learning opportunities to enhance eHealth literacy and self-tracking health strategies within campus environments could be a strategic approach to improve the quality of life and well-being of college students.
Digital Literacy Training for Low-Income Older Adults Through Undergraduate Community-Engaged Learning: Single-Group Pretest-Posttest Study
Authors: Miller Lisa M Soederberg , Callegari Rachel A , Abah Theresa , Fann Helen
Published: April 2024

Background

Digital technology is a social determinant of health that affects older people’s ability to engage in health maintenance and disease prevention activities; connect with family and friends; and, more generally, age in place. Unfortunately, disparities in technology adoption and use exist among older adults compared with other age groups and are even greater among low-income older adults.

Objective

In this study, we described the development and implementation of a digital literacy training program designed with the dual goals of training low-income older adults in the community and teaching students about aging using a community-engaged learning (CEL) approach.

Methods

The training program was embedded within a 10-week CEL course that paired undergraduates (N=27) with low-income older adults (n=18) for 8 weeks of digital literacy training. Older adults and students met weekly at the local senior center for the training. Students also met in the classroom weekly to learn about aging and how to use design thinking to train their older adult trainees. Both older adults and students completed pre- and posttraining surveys.

Results

Older adults demonstrated increased digital literacy skills and confidence in the use of digital technology. Loneliness did not change from pre to postassessment measurements; however, older adults showed improvements in their attitudes toward their own aging and expressed enthusiasm for the training program. Although students’ fear of older adults did not change, their comfort in working with older adults increased. Importantly, older adults and students expressed positive feelings about the trainee-trainer relationship that they formed during the training program.

Conclusions

A CEL approach that brings together students and low-income older adults in the community has a strong potential to reduce the digital divide experienced by underserved older adults. Additional work is needed to explore the efficacy and scalability of this approach in terms of older adults’ digital literacy as well as other potential benefits to both older and younger adults.

The associations between broadband Internet connection, well-being and psychosocial outcomes among middle-aged and older adults in China: findings from a National Longitudinal Cohort Study (Preprint)
Authors: Yang Lu , Lynch Chris , Lee John Tayu , Oldenburg Brian , Haregu Tilahun
Published: April 2024

BACKGROUND

The digital divide impacts health inequality, and access to digital technology is among the major social determinants of health. However, the impact of digital connectivity on the well-being and psychosocial outcomes has not been fully studied.

OBJECTIVE

This study aims to investigate the associations between broadband Internet connection, well-being and psychosocial outcomes among middle-aged and older adults (≥45 years old) in China.

METHODS

A panel data study design of the national sample of China Health and Retirement Longitudinal Study (CHARLS) in 2015, 2018 and 2020 was conducted, including 16,185 participants aged over 45 years. The associations between digital connectivity (broadband Internet connection), loneliness, social participation and life satisfaction were assessed using mixed-effects logistic regression models, adjusting for socioeconomic, behavioral factors, as well as locality. Broadband Internet connectivity, feeling of lonely, social participation, and satisfaction with life, were measured using the self-reported CHARLS questionnaire.

RESULTS

This study observed a substantial increase in digital connectivity from 29.5% in 2015 to 61.1% in 2020. Broadband Internet connection positively correlated with social participation (AOR: 1.34, 95% CI: 1.28-1.41) and life satisfaction (AOR: 1.30, 95% CI: 1.20-1.40). Conversely, the absence of broadband Internet connection was associated with increased loneliness (AOR: 0.81, 95% CI: 0.77-0.86), after adjusting for confounding factors. These associations were consistent across various age, gender, socioeconomic groups, and geographic areas (P<.01).

CONCLUSIONS

This study highlights the potential additional health benefits of digital connectivity beyond the known advantages. Our results suggest the importance of expanding broadband access to enhance social inclusion and life satisfaction. Further research is needed to understand the broader implications and digital determinants of health associated with digital connectivity.

An Integrated Research to Develop a Model of Psychosocial Support for Women who Experience Fetal Death and Abnormality at a Teaching Hospital in Ghana (Preprint)
Authors: Tay Doris Akosua
Published: April 2024

UNSTRUCTURED

This is an exploratory sequential design mixed methods research that aims to develop a psychosocial support model for caring for women who experience fetal death and abnormality in a teaching hospital in Ghana. Health care delivery for such women is inadequate in a country such as Ghana because there is paucity on research of women's experiences and a lack of a model that guides delivery of care that will meet the needs of the women. Usually, the approach to care for the women is also positivist such that it does not consider the situation of the women, culture, and their setting. This work therefore will factor in the social context of which these women are in and generate evidence that will help in producing effective care. Psychosocial support is a key component in reducing anxiety and depression with such experience and there is confirmed evidence that more work is needed to develop a framework of care for health workers to use. Grounded theory will be used to collect qualitative data on the women, health workers and community and this will help in developing the model. Hypotheses will be made based on findings from grounded theory. The quantitative method that will be employed is cross-sectional. Themes from the qualitative data will be used to develop and test quantitative instrument. Quantitative data will be collected from women, healthcare workers and community who were not part of the qualitative data.Statistical analysis would be performed.
The Translation Strategies of Chinese-characteristic Vocabulary from the Perspective of Eco-translatology—Taking the 2023 Chinese Government Work Report as an Example
Authors: Zhong Huang
Published: April 2024

The English translation of the Chinese government Work Report every year is of great international significance and function. It provides other governments and the public with access to key information about China’s policy direction, governance measures, and social progress. It is also an important means for China to showcase its national image, promote economic development and strengthen its global partnerships. This paper attempts to interpret and analyze the English version of the government work report from the perspective of Eco-translatology, and sort out the translation strategies of a large number of words with Chinese characteristics so as to provide new ideas and perspectives for the translation and dissemination of Chinese excellent culture.

Published: April 2024

In the context of digital taxation, constructing an enterprise financial compliance management system is an important means to ensure compliance with tax regulations, optimize tax management, and improve economic efficiency. As a crucial component of modern tax administration, "digital taxation" imposes new requirements on enterprise financial compliance management. This paper aims to explore how to construct an effective enterprise financial compliance management system under the backdrop of "digital taxation" to enhance the quality of accounting information and financial compliance, thereby reducing financial and tax risks and promoting the sustainable development of enterprises.
BUBANJ MEMORIAL PARK: A MEMORIAL TO THE VICTIMS OF NAZI TERROR AND MASS EXECUTIONS IN WORLD WAR II
Authors: Mirić Aleksandra , Mirić Filip
Published: April 2024

The "Bubanj" Memorial complex, locate on Bubanj Hill at the outskirts of Niš, was built with the aim of marking the site of mass executions of the innocent victims of Nazism in the Second World War. It is a symbol of suffering but also of resistance, struggle and desire for freedom, embodied in the symbolic depiction of three huge clenched fists. The "Three fists” symbolize resistance and defiance against fascism. They are a recurrent reminder of the importance of freedom as the supreme human value. The paper first briefly presents the eugenics policy, which was the ideological basis of Nazism and ferocious Nazi crimes. Then, the authors outline the historical circumstances leading to the establishment of the Concentration Camp Crveni krst in Niš and Bubanj Hill as the execution site. The central part of the paper focuses on the construction of the Bubanj memorial complex, its importance in the post-war Yugoslav society, and its current position on the cultural map of Serbia. While calling attention to the agony sustained by victims of Nazi terror in these parts of Serbia, the authors highlight the strength and resilience of the people who endeavored to preserve and defend freedom and right to dignified life as ultimate human values.
THE NATIONAL ASSEMBLY OF SERBIA AS A ‘’WORKING’’ PARLIAMENT: LEGAL PROSPECTS AND ACHIEVEMENTS
Authors: Pejić Irena
Published: April 2024

The paper examines the legal framework and parliamentary practice that provides opportunities for the National Assembly of Serbia to act as a “working assembly”. After theoretical considerations on the “talking” and “working” assemblies, the author analyzes some issues relating to the Rules of Procedure which regulate the organization, working conditions and functioning of the National Assembly. The subject matter of analysis are the parliamentary committees, the Conference of Presidents, and the plenary sessions of the National Assembly. The Rules of Procedure indicate that there was an intention for the parliament to acquire the characteristics of a “working” assembly. However, parliamentary practice and the absence of good customs indicate that this intention was not achieved in practice. The general conclusion would be that the National Assembly has retained most of the attributes of the “talking” assembly, which performs most of its work in the plenum.
U-Pb geochronology and Hf isotopes of the Grenvillian Río Hondo gneisses, Puebla: redefining the western edge of Oaxaquia

In situ Río Hondo (Puebla, southern Mexico) gneiss samples, as well as clastic samples recovered from the nearby-outcropping latest Paleozoic Matzitzi Formation, a fluvial unit mainly sourced by Grenvillian rocks,  were historically interpreted as representative of the northernmost exposures of the Oaxacan Complex, the largest outcrop of ortho and metasedimentary units, made up of mostly 1.0–1.3 Ga protoliths, affected cfby local migmatization (ca. 1.1 Ga) and granulite facies metamorphism at ca. 0.98 Ga, constituting the most prominent outcrop of the Oaxaquia microcontinent.

U-Pb geochronology and Lu-Hf isotopic determinations in zircon by LA-(MC)-ICP-MS were performed on both in situ and clast samples. In situ basement samples record a ca. 1.2 crystallization event, together with a younger one at ca. 1.02 Ga. both lacking inherited >1.3 Ga components. The clasts have an unimodal zircon U-Pb age distribution, recording a crystallization event at ca. 1.2–1.27 Ga. Scarce inherited zircon cores between ca. 1.4–1.6 Ga were found, with only a few samples with a broader age distribution, suggesting a detrital protolith with zircon cores as old as ca. 1.8 and 2.4 Ga. No zircon overgrowths or geochemical-petrographic evidences are indicative of granulite metamorphism. Furthermore, all the studied metaigneous samples show discordant zircon ages produced by Pb loss events barely constrained between the latest Paleozoic to the Mesozoic.

Hf isotopes reveal that zircon crystals from clasts have a range of εHf (1.25 Ga) ≈+1 to +5 and yield Hf model ages from 1.7 to 1.9 Ga. On the other hand, the The zircon Hf isotopes of one analyzed basement sample reveal a higher range of εHf (1.25 Ga) ≈+7 to +9, and Hf model ages from 1.5 to 1.6 Ga.

Both ≈1.2 Ga and 1.02 Ga events are consistent with magmatic ages previously documented elsewhere in Oaxaquia, interpreted as indicating portions of the NW Amazonia-Oaxaquia arc system with cratonic influence or to slices of Baltica thrust over Oaxaquia during the Grenville orogeny. However, the absence of granulite facies indicators, such as zircon metamorphic ages and/or granulite paragenesis (typically, in other Oaxaquia samples, orthopyroxene and garnet) are interpreted as prime evidence that the studied samples didn’t undergo such high grade of metamorphism. Río Hondo gneisses, as this sequence is informally named, must belong to a source that had the influence of an older continental crust and can be tentatively associated either with rocks recently described in the Sierra de Juárez, or those belonging to the central basement of the Maya block, currently exposed farther to the SE in Chiapas.

One hundred forty 10-day-old SPF chickens were assigned to 4 groups. Fifty birds in group 1 and 20 birds in group 3 were inoculated with 600 µL (105 TCID50) of strain WF2014, 50 birds in group 2 and 20 birds in group 4 were inoculated with 600 µL DMEM/F-12 medium by intramuscular injection into the leg muscles. Birds in groups 3 and 4 were immunized at 17 days old with the Newcastle diseases (NDV) vaccine. At 3, 7, 11, 15 and 19 days dpi, seven birds from each groups 1 and 2 were randomly weighed and necropsied. Organs or tissues with macroscopic pathological changes, small intestines, and immune organs were collected for histopathological observation, measurement of the ratio of the length of the villus to the depth of the crypt (V/C), apoptosis, and determination of viral load. Chicken sera from groups 3 and 4 were collected at 7, 14, and 21 days after immunization, and antibodies against NDV were evaluated. The results showed that hepatitis, pancreatitis, proventriculitis, a decrease in the V/C ratio in the duodenum, and body weight were observed in WF2014 infected chickens. Apoptosis, severe lesions, and high viral load were found in the bursa of Fabricius, spleen and thymus, and the humoral immune response was suppressed in infected chickens. These suggested that FAdV-8b infection implicated growth retardation and immunosuppression in chickens, and this will lay the foundation for a further study of the mechanism of FAdV-8b infection in chickens.
Sobre el anacronismo. Dos casos en la literatura latinoamericana contemporánea
Authors: Magaña Cantón Isaac Gustavo
Published: April 2024

Este artículo examina los conceptos de “anacronismo” y “experiencia anacrónica” en un contexto contemporáneo. A partir del análisis de dos obras latinoamericanas contemporáneas —Muerte súbita (2013), de Álvaro Enrigue, y El libro centroamericano de los muertos (2018), de Balam Rodrigo—, este artículo propone que algunas conexiones no-lineales y lógicamente injustificables entre eventos ya distantes en el tiempo, ya distantes en el espacio, tienen la capacidad de producir en el lector una experiencia de vastedad, mediante la cual estas conexiones no solo se hacen válidas sino irrefutables. Conexiones que llamamos aquí anacrónicas, en tanto que son apariciones de lo que parece formar parte del pasado en el tiempo presente, pero cuyo sentido en realidad desborda la definición tradicional del término, pues las relaciones que estos anacronismos animan no son jerárquicas sino simultáneas.

La tradición del borde
Authors: Rojas Rafael
Published: April 2024

Este ensayo intenta recorrer algunas apro ximaciones al discurso de la identidad de América Latina y el Caribe, en la historia intelectual de la región, que no partieron de la afirmación o la negación de las claves antropológicas o ideológicas del latinoame ricanismo. En autores como el dominicano Max Henríquez Ureña, la cubana Lydia Cabrera, el brasileño Sérgio Buarque de Holanda y el cubano José Lezama Lima, el texto intenta explorar estrategias discur sivas que buscaron una disolución de las fronteras identitarias por medio del pana fricanismo, la latinidad o un americanismo que rehuía de las hegemonías del sentido en los debates intelectuales de la Guerra Fría.

Abstract: Cloudy weather classification is a vital task in meteorology and remote sensing, facilitating various applications such as weather forecasting, climate monitoring, and environmental analysis. In this study, we explore the application of convolutional neural network (CNN) techniques for classifying cloudy weather conditions using the Cloudy Weather Dataset sourced from Kaggle. The primary CNN architectures investigated include AlexNet, LeNet, and ResNet. The dataset undergoes preprocessing steps, including resizing and normalization to floating-point representation. Additionally, for calculating cloud cover percentage, the images are processed through grayscaling followed by thresholding. The performance of each CNN model is evaluated based on metrics of accuracy, that is providing insights into their effectiveness for cloudy weather classification
