Authors: Sharapov Serhii , Krmela Jan , Husiev Danylo , Verbytskiy Anton , Bocko Jozef
Published: July 2024

The article solves the problem of heat utilization from combustion products in boiler plants. The proposed solution involves extracting heat to preheat the network water for the heating system and implementing additional heat utilization using a liquid-vapor jet apparatus. This will allow for additional working steam generation in the main steam generator and the unit based on the liquid-vapor jet apparatus. The article provides schemes and descriptions of traditional and proposed plants, indicating their design differences from the basic scheme. Comparative thermodynamic analysis of the proposed installation for additional recuperative heat utilization and the basic scheme is carried out, in which heat utilization occurs due to the extraction of heat from combustion products to preheat the network water of the heating system. As a result, the main thermodynamic parameters of the cycles of basic and proposed schemes are obtained, and the values of the capacities on the apparatuses included in these installations are determined. The energetic potential obtained from additional heat utilization is 8 %, which can be used for electricity generation. Exergy analysis assesses the efficiency of additional heat utilization in boiler plants using units based on liquid-vapor jet apparatus. As a result of the exergy analysis, the value of the exergetic efficiency of the scheme with additional heat utilization was obtained, which is 1.47 times higher than that of the basic scheme. A thermoeconomic analysis was performed to determine the cost values. Implementing the new scheme enables reducing the specific cost of the heating unit by 48 % and increasing the amount of steam generated in the installation by an additional 18 %.

Adaptive architecture – main development directions
Authors: Ponomarev A. V.
Published: July 2024

This article considers promising directions of adaptive architecture, one of the most dynamically developing concepts in the field of design and construction. A wide range of objects constructed using advanced technological solutions are studied and classified as adaptive objects, spaces, or environments. Special attention is paid to the following three aspects of adaptive architecture. First, adaptive architecture should be based on the principle of energy efficiency, including conservation of energy and resources and use of clean energy, contributing to the creation of buildings with a high environmental coefficient. Second, the living environment should meet the requirements of flexibility and mobility, representing the interaction between the environment and the human. This function of the environment is aimed at creating spaces conducive to changes depending on public and personal needs. Third, the relations between three components––people, environment, and digital technologies––should be considered. The response to the challenge of modernity in the late 20th and early 21st century concerned the restructuring of the technological process towards the search for the most effective directions in the field of creating sustainable objects, spaces, and environments. Digital reality becomes a connecting element, which contributes to the creation of an adaptive space flexibly responding to changes in the environment and human needs.
Hidden in the bark: the unexpected presence of the leaf-toed gecko, Euleptes europaea (Gené, 1839) (Squamata, Sphaerodactylidae), in Sicily
Authors: Giacalone Gabriele , Faraone Francesco Paolo , Pecoraro Marco , Sarà Maurizio
Published: July 2024

We report the first observations regarding the presence of the leaf-toed gecko, Euleptes europaea , in Sicily. During field activities for environmental impact assessment several leaf-toed gecko individuals were found in a restricted coastal area in the north-west of the island, near the city of Palermo. Further surveys were then carried out to better assess the presence of the species. A total of 21 E. europaea individuals were observed in a small area of approximately 4.4 hectares, consisting of mixed eucalyptus and pine reforestation. Out of the 21 individuals, there were 14 males, 5 females, and 2 whose sex could not be determined. Additionally, at least two pregnant females were observed. Leaf-toed geckos were found exclusively under eucalyptus bark, syntopic with two other Gekkota species ( Tarentola mauritanica and Hemidactylus turcicus ). The presence of such a breeding population of E. europaea is probably limited to a small area. However, our results do not allow us to clearly assess either its origin or its actual distribution and demography, therefore new field investigations are necessary.

Authors: Mulu Gashaw Adugna , Kerebih Mulu Sewinet , Hailu Dawit Asregedew
Published: July 2024

This study aims to identify groundwater potential zones (GWPZs) utilizing multi-influencing factor, geographical information system (GIS)-based analytical hierarchy processes (AHPs), and remote sensing in the Gorezen watershed, Ethiopia. Weighted overlay analysis was used in this study to integrate nine thematic layers. The Gorezen watershed is primarily covered by regions with roughly low groundwater potential, according to the results, which were linked to the kinds of geology and geomorphological settings. Receiver operating characteristic curves and samples of observed groundwater well-yielded data were used to validate the GWPZ map. Additionally, field observations confirmed that a high degree of agreement was obtained. The cross-validation results show that AHP is a lot more successful approach (accuracy 0.87) for obtaining groundwater potential maps. Thus, it is acceptable to identify the GWPZs utilizing integrated methodologies that combine two multi-criteria decision analysis techniques with the aid of a GIS environment.
The Prospect of Probiotics to Treat Metabolic Syndrome
Authors: Ramadhan Andika Yusuf , Rosdiana Dewi Selvina
Published: July 2024

Metabolic syndrome remains as a major health problem in the world today, with a prevalence of 23.4% in people aged 26-82 years. A high-fat, high-carbohydrate diet and lack of physical activity are considered as one of the triggers for metabolic syndrome. Dysbiosis is a condition where there is an imbalance between pathogenic and non-pathogenic bacteria in the human gut. Currently, an association has been found between dysbiosis and metabolic syndrome. Dysbiosis causes the generation of fermentation products in the form of active metabolites that can modulate hormones and other physiological functions. In metabolic syndrome, low-grade inflammation, energy metabolism, and disruption of the gut brain axis are thought to be the main mechanisms of the development of metabolic syndrome due to dysbiosis. Probiotics may be a promising therapeutic agent in the treatment of metabolic syndrome, by improving dysbiosis to eubiosis. Based on previously conducted clinical trials, it is currently known that probiotics can improve lipid profiles, fasting blood glucose, homeostatic model assessment for insulin resistance (HOMA-IR), vascular cell adhesion molecule 1 (VCAM-1), glucagon-like peptide-1 (GLP-1), peptide YY (PYY), and body mass index (BMI). However, the results found are still varied, so a dose ranging study is needed to determine the duration, bacterial composition and dose of probiotics as a therapeutic agent for metabolic syndrome. Keywords: insulin resistance, dysbiosis, gut-brain axis
Cyclic voltammetric and characterization studies of electrodeposited copper-indium for thin-film solar cell application
Authors: Farooq Leher
Published: July 2024

Abstract. Copper-indium layers were grown on a carbon substrate by a one-step electrodeposition technique. Four deposition electrolytes were prepared: Two unitary electrolytes comprising of 300 mM copper (II) chloride and 700 mM trisodium citrate and 300 mM indium (III) chloride and 700 mM trisodium citrate; two binary electrolytes comprising of 300 mM copper (II) chloride, 300 mM indium (III) chloride and 700 mM trisodium citrate for deposition at potentials of -0.6 V and -0.9 V, respectively. The pH of the solution was left unaltered at 4.8. X-ray diffraction studies showed the produced copper indium layers had an amorphous structure. From the scanning electron microscopy studies, it was found that copper indium layers indicated a small grain size and grain shape was irregular. The structure was not compact. Energy dispersive spectroscopy showed presence of low percentages of copper and indium in all four samples and stoichiometric molar ratios of Cu:In of 1:1 can be achieved using deposition potentials between -0.6 to -0.9 V. SEM, EDS and XRD characterization helps in the identification of the reaction mechanism, the structure and morphology of the films deposited under different conditions. These characterization studies will assist in enhancing the efficiency of the thin-films deposited for maximum conversion of sunlight to electricity using this sustainable method. In this present study, an attempt has been made to obtain near stoichiometric films for higher efficiencies.

Authors: ELAMIN Abdin Y.
Published: July 2024

Abstract. This paper addresses the integration of a point absorber type wave energy converter into power grids, a process complicated by wave energy's intermittent and unpredictable nature. It proposes a sliding mode control strategy with an exponential reaching law in a voltage-oriented control architecture for the grid-side converter of the point absorber. The control objective is to maximize the transfer of generated power to the electrical grid, while concurrently stabilizing the DC bus voltage at a predetermined value and achieving a unity power factor. Results from simulations conducted within a MATLAB framework underscore the efficacy of the sliding mode control approach in sustaining specified DC bus voltage values, and in regulating the direct and quadrature currents by minimizing their respective tracking errors.

An automated and cost-efficient method for photovoltaic dust cleaning based on biaxially oriented polyamide coating material
Authors: Halwani Said
Published: July 2024

Abstract. Photovoltaic (PV) systems have been at the forefront of renewable energy technologies. However, they are highly dependent on environmental parameters that affect their performance and longevity. Dust accumulation presents a critical factor in the performance of PV systems, leading to minimum system efficiency under largely dusty conditions. Several cleaning methodologies have been proposed in scientific literature to prevent dust accumulation at the forefront of PV modules. However, most cleaning methodologies are cost-consuming, time-consuming, complex in implementation, or require huge manpower to implement them. This paper proposes a cost-efficient and automated method for dust accumulation prevention and cleaning based on Biaxially Oriented Polyamide (BOPA) coating material. This transparent thin film is applied on the front surface and integrated based on an automated control scheme, for controlled rotation every 2 weeks, to prevent dust accumulation on the forefront of the PV surface. The performance of the BOPA coating film was experimentally assessed for 45 days, assessing the irradiance and electrical performance of the PV modules. The application of BOPA maintained a PV module electrical efficiency of 12.19%, while the dusty PV module electrical efficiency is reduced to 7.79% at high dust accumulation levels. Moreover, the BOPA material has demonstrated its ability in capturing solar irradiance, without losses for the visible light, hence maintaining an electrical current of 2.15 A, while the dusty PV module loses its electrical current by 40%, maintaining an electrical current of 1.28 A.

Authors: Marcuzzi Anna , Klevanger Nina Elisabeth , Aasdahl Lene , Gismervik Sigmund , Bach Kerstin , Mork Paul Jarle , Nordstoga Anne Lovise
Published: July 2024

Background

Self-management is endorsed in clinical practice guidelines for the care of musculoskeletal pain. In a randomized clinical trial, we tested the effectiveness of an artificial intelligence–based self-management app (selfBACK) as an adjunct to usual care for patients with low back and neck pain referred to specialist care.

Objective

This study is a process evaluation aiming to explore patients’ engagement and experiences with the selfBACK app and specialist health care practitioners’ views on adopting digital self-management tools in their clinical practice.

Methods

App usage analytics in the first 12 weeks were used to explore patients’ engagement with the SELFBACK app. Among the 99 patients allocated to the SELFBACK interventions, a purposive sample of 11 patients (aged 27-75 years, 8 female) was selected for semistructured individual interviews based on app usage. Two focus group interviews were conducted with specialist health care practitioners (n=9). Interviews were analyzed using thematic analysis.

Results

Nearly one-third of patients never accessed the app, and one-third were low users. Three themes were identified from interviews with patients and health care practitioners: (1) overall impression of the app, where patients discussed the interface and content of the app, reported on usability issues, and described their app usage; (2) perceived value of the app, where patients and health care practitioners described the primary value of the app and its potential to supplement usual care; and (3) suggestions for future use, where patients and health care practitioners addressed aspects they believed would determine acceptance.

Conclusions

Although the app’s uptake was relatively low, both patients and health care practitioners had a positive opinion about adopting an app-based self-management intervention for low back and neck pain as an add-on to usual care. Both described that the app could reassure patients by providing trustworthy information, thus empowering them to take actions on their own. Factors influencing app acceptance and engagement, such as content relevance, tailoring, trust, and usability properties, were identified.

Social Media Programs for Outreach and Recruitment Supporting Aging and Alzheimer Disease and Related Dementias Research: Longitudinal Descriptive Study (Preprint)
Authors: Teano Anthony L , Scott Ashley , Gipson Cassandra , Albert Marilyn , Pettigrew Corinne
Published: July 2024

BACKGROUND

Social media may be a useful method for research centers to deliver health messages, increase their visibility in the local community, and recruit study participants. Sharing examples of social media–based community outreach and educational programs, and evaluating their outcomes in this setting, is important for understanding whether these efforts have a measurable impact.

OBJECTIVE

The aim of this study is to describe one center’s social media activities for community education on topics related to aging, memory loss, and Alzheimer disease and related dementias, and provide metrics related to recruitment into clinical research studies.

METHODS

Several social media platforms were used, including Facebook, X (formerly Twitter), and YouTube. Objective assessments quantified monthly, based on each platform’s native dashboard, included the number of followers, number of posts, post reach and engagement, post impressions, and video views. The number of participants volunteering for research during this period was additionally tracked using a secure database. Educational material posted to social media most frequently included content developed by center staff, content from partner organizations, and news articles or resources featuring center researchers. Multiple educational programs were developed, including social media series, web-based talks, Twitter chats, and webinars. In more recent years, Facebook content was occasionally boosted to increase visibility in the local geographical region.

RESULTS

Up to 4 years of page metrics demonstrated continuing growth in reaching social media audiences, as indicated by increases over time in the numbers of likes or followers on Facebook and X/Twitter and views of YouTube videos (growth trajectories). While Facebook reach and X/Twitter impression rates were reasonable, Facebook engagement rates were more modest. Months that included boosted Facebook posts resulted in a greater change in page followers and page likes, and higher reach and engagement rates (all P≤.002). Recruitment of participants into center-affiliated research studies increased during this time frame, particularly in response to boosted Facebook posts.

CONCLUSIONS

These data demonstrate that social media activities can provide meaningful community educational opportunities focused on Alzheimer disease and related dementias and have a measurable impact on the recruitment of participants into research studies. Additionally, this study highlights the importance of tracking outreach program outcomes for evaluating return on investment.

Authors: Senathirajah Yalini
Published: July 2024

BACKGROUND

During the COVID-19 pandemic in 2020, hospitals encountered numerous challenges that compounded their difficulties. Some of these challenges directly impacted patient care, such as the need to expand capacities, adjust services, and utilize new knowledge to save lives in an ever-evolving situation. Additionally, hospitals faced regulatory challenges.

OBJECTIVE

Objective: This article presents the findings of a qualitative study that compares the effects of reporting requirements on a small independent hospital (SIH) and a large, networked hospital (LNH) during the pandemic.

METHODS

Methods: We employed both quantitative and qualitative analyses. The researchers conducted a total of 51 interviews, which were thematically analyzed. We quantified the changes in regulatory reporting requirements over the first 14 months of the pandemic.

RESULTS

Results: These requirements placed a significant time burden on key clinical personnel at the SIH, consequently reducing the time available for patient care. Conversely, the LNH had dedicated non-clinical staff responsible for reporting duties, and their robust health information system facilitated this work.

CONCLUSIONS

Conclusions: The discrepancy in health information technology (HIT) capabilities suggests that there may be significant institutional inequities affecting smaller hospitals' ability to respond to a pandemic and adequately support public health efforts. The healthcare policy implications of these findings are discussed.

Hal ini sering menghadapkan dokter dengan tantangan yang lebih besar daripada yang dihadapi saat merawat pasien respon opioid. Tujuan pengobatan opioid adalah menghilangkan nyeri akut dengan efektif, mencegah penarikan obat, memberikan bantuan masalah sosial, kejiwaan dan perilaku, dan memastikan kesinambungan perawatan jangka panjang. Pendekatan farmakologis menggabungkan kelanjutan dari pengobatan biasa, penggunaan jangka pendek, dan peresepan obat non-opioid dan ajuvan, untuk meningkatkan efek analgetik sekaligus menurunkan toleransi opioid dan hiperalgesia yang diinduksi opioid.

Objective: This study was conducted with the objective to measure the Subfoveal Choroid thickness and correlate it with the diminished visual acuity in patients with Diabetes Mellitus Type 2, who develop macular edema and to study the effect of Intravitreal injections of Ranibizumab during follow up.
Methods: A cross sectional, interventional study conducted in 52 patients with uncontrolled Diabetes Mellitus Type-2 with macular edema by measuring the Subfoveal Choroid thickness with the help of manual caliper function present in the Heidelberg Spectralis OCT program. Patients with SFCT less than 450 microns were included. The SFCT and the corresponding visual acuity were measured before and after Intravitreal Ranibizumab injections 1.25mg (0.05mL) at monthly intervals for 3 months and correlated with age, gender, and choroid thickness.
Results: Out of 52 patients there were 31 (59.61%) females and 21 (40.38%) males. 50% of the patients were aged between 50 and 60 years and 50% patients were aged between 60 and 70 years. The patients responding to the Intravitreal injections in terms of best-corrected visual acuity (BCVA) between the reinjection and post-injection were found to be statistically important (p=0.001). The subfoveal Choroidal thickness (SFCT) variations, before and after injections were found to be statistically significant at the end of 3 months (p<0.05).
Conclusions: Injection Ranibizumab was found to have a significant role in the reduction of average SFCT and in addition clear evidence of improved BCVA.

This research discusses the phenomenon of hate speech in Hilarion Heagy's conversion news on Twitter. Hilarion Heagy, a former Orthodox priest who later embraced Eastern Catholicism before ultimately converting to Islam, has sparked significant controversy within religious circles, eliciting varied reactions, especially on social media. This research addresses a significant gap in the literature by examining hate speech in the context of religious conversion. Therefore, this research aims to identify types of hate speech and find out the intent behind hate speech. This research utilizes the National Police Chief's circular number SE/6/X/2015 to identify types of hate expressions and uses Searle's illocutionary speech act theory to explain the meaning behind hate expressions. In this research, data was taken from comments on Twitter related to the news of Hilarion Heagy's conversion. The results of the research found that the expressions of hatred in the news about Hilarion Heagy's conversion were related to religious issues. The outcomes found five types of hate speech, with the most performed being Blasphemy (17 times), followed by Provoking (11 times), Defamation (10 times), Insult (7 times), then the least one being Spreading fake news (5 times). As for the types of illocutionary acts, the most dominant was Assertive (40 times), followed by Directive (7 times) and Expressive (3 times). There were no Commissive and Declaration types found at all.

This quasi-experimental study investigates the effectiveness of Nearpod, a student-response-system, on elevating student engagement in Foreign Language for Specific Purposes (FLSP) classes. Utilizing Nearpod's interactive features to deliver the materials and activities through a shareable link, the study aimed to create a dynamic and immersive learning experience. The study involved 74 students from an FLSP course, divided into control and experimental groups. The experimental group were taught using Nearpod while the control group received regular instructions. Engagement levels were measured using a self-report questionnaire based on Wang et al. (2016), encompassing four domains of student engagement. The Mann-Whitney U-Test revealed that Nearpod significantly increased overall student engagement (U = 263.500, p < .05). Notably, behavioral, emotional, and social engagement showed significant improvements, while cognitive engagement did not (U = 450.500, p > .05). This empirical results show that Nearpod significantly enhances overall student engagement and positively impacts behavioral, emotional, and social engagement in FLSP integrated classes. However, cognitive engagement remains unaffected, suggesting a need for further exploration of strategies to address this aspect.This research provides valuable insights for language instructors, highlighting the potential of technology to foster engaging and interactive learning environments.

Published: July 2024

This paper tends to examine the impact and challenge of the China-Lao Railway that has been operating since December 2021 on Lao’s economic and social development. As a landlocked country, Lao has been facing difficulties in boosting its economic and human improvement due to the lack of infrastructure and development capacity. However, Lao is also geographically strategic because its position is in the middle of the Indo-China area. It makes Lao eagerly wants to be a land-linked country through the railway that connects China and other countries in the region. Under the project Belt and Road Initiative, Lao, for the first time, has a high-speed railway that links the capital city, Vientiane, and Boten, the China-Lao border, and further connects Kunming, the Chinese provincial capital. After one year of implementation, the positive impact has been felt by Laotians such as the tourism sectors, goods flow, and education sectors. However, land compensation and environmental issue are the negative impacts that Laotians encounter. Lao also might face some challenges to sustaining this railway’s benefits namely a debt trap, transnational crime, and severe corruption.
