Authors: Robles-Lozano Geolain ,   University of Curaçao, Saldarriaga-Zuluaga Sergio Danilo , Zuluaga-Ríos Carlos David ,   Institución Universitaria Pascual Bravo
Published: July 2024

Because of the ongoing discussion about global warming, many nations have developed several approaches to address this problem. Some strategies are: renewable energy integration, agricultural robotic solutions, and electric vehicle penetration. The last strategy, the electric vehicle (EV), has gained considerable attention due to the paradigm shift in the transport sector driven by internal combustion engines and EV penetration can also achieve eﬀicient operation of power grids. However, there are numerous challenges associated with the penetration of these technologies within active distribution networks. It is necessary to analyze the increased amount of electricity consumption in these grids, the degradation in the voltage profile in these networks and the hosting capacity assessment of electric vehicle integration in these grids. This paper analyzes the influence of EV penetration on a 34-bus active distribution system through five EV stations and proposes two alternatives for improving the introduction of these technological elements. Specifically, it analyzes the voltage levels at the system nodes and proposes an intelligent management of resources through capacitor banks and transformer taps. From the results, the effects on the network were voltage drop on some bus bars and an increase or decrease of the loading on lines depending on the EV penetration. It is also evident that 9% of the bus bars were not working under acceptable voltage ranges in the worst-case scenario.
On The Thermalization of One-Dimensional Lattices. I. Microcanonical Ensemble
Authors: Vinogradov G.A. , Lakhno V.D.
Published: July 2024

In numerical simulation of biomacromolecule, the issues of thermalization, i.e., equal distribution of energy over the degrees of freedom, occupy an important place. In this paper we consider some mechanisms of lattice thermalization: Chirikov resonances, wave turbulence and some others. We consider thermalization in a microcanonical ensemble when the system is isolated from external fields and the total energy is conserved. Although microcanonical ensembles are rarely used in practical calculations, however, the basic ideas about the thermalization mechanisms are obtained for these systems. The main attention is paid to the consideration of the lattices thermalization with Fermi-Pasta-Ulam-Tsingou potentials, since the main efforts to understand the basis of thermalization have been made precisely for lattices of this type. The role of solitons and breathers in thermalization is discussed.

Published: July 2024

Hop stunt viroid (HSVd) is the causal agent of citrus cachexia, which can lead to significant crop losses. As part of a preventive management strategy, it is essential to use healthy plants from a certification program. This study aimed to, healthiness of 17 citrus cultivars was evaluated against HSVd using both biological and molecular diagnostics. For biological diagnosis, Etrog citron (Citrus medica L.) clone Arizona 861 S1 was used as an indicator plant, incorporating negative and positive controls for HSVd infection. For molecular diagnosis, reverse transcription polymerase chain reaction (RT-PCR) technique was employed with specific primers for viroid detection. Results indicated that six months after inoculation, the positive control exhibited symptoms associated with viroid infection, such as necrosis in the petiole and stem, leaf epinasty, and necrosis in the midvein. In contrast, both the negative control and evaluated citrus cultivars showed no symptoms. These findings were supported by molecular analysis, which allowed the amplification of a viroid genome region only in the positive control. Both biological and molecular diagnosis confirmed the absence of HSVd in the citrus varieties assessed. This study will allow the evaluation of the citrus plant collections used in the foundation category as a source of buds for plant multiplication of registered and certified seeds for citrus propagation nurseries in Colombia.

Published: July 2024

As the world population continues to grow, the demand for clean water is increasing daily, making it a crucial resource to access. However, there are ways to harness abundant resources like solar energy and seawater to produce clean water. The present studies have conducted experimental investigations to convert seawater into freshwater using solar stills, where solar energy is utilized as the primary heat source for evaporation. The temperature distribution inside the solar stills was analyzed using a flat plate made of three different materials: copper, stainless steel, and aluminum. To examine the temperature distribution and performance of the solar stills, researchers employed computational fluid dynamics simulations (Ansys R15.0). The results showed variations in temperature distribution among the three plate materials. Copper flat plates achieved the highest temperature, approximately 44.5 Celsius, followed by aluminum at 43.91 Celsius, while stainless steel exhibited the lowest temperature at around 42.01 Celsius. The average heat flux across the three materials was approximately 581 W/m2. Additionally, observations indicated that the amount of convection occurring in copper flat plates was 121.108 Watts; in aluminum, it was 118.517 Watts; and in stainless steel, it was 105.05 Watts. The radiation energy for stainless steel flat plates was 29.93 W; for copper, 16.14 W; and for aluminum, 13.49 W.

Published: July 2024

Metal foundries still rely heavily on crucible furnaces. The current furnace design, which is currently being used by the partner industry, has been found to be not properly designed and will result in a reduction in efficiency. CFD simulation will be used to find the optimal melting furnace design. This research simulation consists of 3 stages: pre-processing, solving, and post-processing. There are two furnace geometries, cylindrical and hexagonal, while the burner location will be divided into 3 positions, namely P1, P2, and P3. The most optimal furnace design will be used as a basis for the verification testing process. The process of comparing the old and the new smelting furnace design is carried out to understand the performance and characteristics of each furnace. The simulation results for the average crucible temperature in the cylindrical furnace were obtained as follows: 288.5 ºC for the P1 burner, 306.2 ºC for the P2 burner, and 284.5 ºC for the P3 burner. Meanwhile, the simulation results show that the average crucible temperature value in the hexagonal furnace is 290.0 ºC for the P1 burner, 281.6 ºC for the P2 burner, and 237.8 ºC for the P3 burner. The verification testing process produced an average crucible temperature value of 237.5 ºC. Furthermore, the comparison test from the old and new furnace designs to melt 2.5 kg of aluminium at 680 ºC with the old furnace took approximately 30 minutes and 33 minutes with the new furnace. The new furnace produced much more uniform melting than the old furnace.

Published: July 2024

The transition of learning from online to offline has an impact that can be a problem for its implementation if students cannot adapt properly. The low ability of students in the adaptation process will cause negative reactions that arise not only from physical reactions but also psychologically due to academic demands and pressure to adapt quickly to environmental changes. This situation makes students vulnerable to experiencing academic stress. This research aims to see the relationship between academic resilience and academic self-efficacy of students in dealing with academic stress due to the transition of the learning system. Academic resilience is measured using the Academic Resilience Scale (ARS-30), academic self-efficacy is measured using The Academic Self-Efficacy Scale (TASES), and academic stress is measured using the academic stress inventory. The sample was 354 students of University X. The data were analyzed using multiple regression analysis techniques. The results showed that academic resilience and academic self-efficacy predicted academic stress (R-squared equals .137; p less than .01) during the transition from online to offline learning.

Authors: Dirgantara Made , Karelius Karelius , Rumbang Nyahu
Published: July 2024

The process of torrefaction is a thermochemical process that is widely used for the conversion of biomass into renewable fuels. In this study, the significance of temperature was determined by carrying out the torrefaction process at temperatures ranging from 275 to 350 degrees Celsius with a fixed residence time of 60 minutes. To ascertain the impact of time on the process, the torrefaction procedure was conducted over a residence time of 20 to 60 minutes at 300°C. Increasing the torrefaction temperature can substantially increase the palm kernel shell's calorific value, decrease water content, decrease volatility, increase fixed carbon, especially from 275 oC to 325 oC, and decrease ash content from 275 oC to 300 oC. Increasing the torrefaction residence time can significantly increase the palm kernel shell's calorific value from 20-40 minutes, decrease ash content and volatile content, and increase fixed carbon from 20-30 minutes. The residence time did not affect the water content in torrefaction temperature at 300 oC. The statistical analysis revealed that temperature and residence time have a substantial impact on the heating value and proximate analysis.

Published: July 2024

It has been for years that Indonesian education institutions rely on foreign language tests to assess students for their admission and graduation requirements. One of the instruments used is Test of English Proficiency (TEP) due to its validity, reliability, objectivity, and its unbiased characteristics to measure students’ ability in English competence. Although studies on the use of TEP have been extensively carried out, little is known about the use of such a test by students with disabilities. To fill the gap, the present study was conducted to investigate the experiences of students with disabilities in learning the TEP preparation using the Single-Bite-Size (SBS) strategy. Data were gathered through an in-depth interview with students with disabilities. The queries raised were about the participants’ problems in learning English, feeling after the implementation of SBS, the experience in taking TEP, and the experience in joining the TEP preparation program. The narrative analysis showcases that promoting SBS strategy in the TEP preparation teaching program could assist students improve their materials comprehension. The study also unpacks that their personalized learning much occurred in the classroom.

Tourism Destination Image (TDI) is complex, dynamic and multidimensional by nature and shaped by a multitude of events, interactions and sensory impressions, especially once the tourist is at the destination, generating tourists' engagement on social media networks. This study aims to measure the online destination image (ODI) portrayed in user-generated content (UGC) on social media by employing the sentiment analysis method. Data were extracted from Facebook and Instagram on the Visit Algarve social media profile. The Algarve region is situated in the south of Portugal and is one of Europe's most popular tourist destinations. The main results shed light on the relevance of intangible heritage experiences as triggers of positive feelings about the destination. Content shared about tourists' activities in the region generates more engagement in the tourism destination's social media. Tangible heritage received the lowest rated sentiment, and destination agents should strategically look into it as there are opportunities for destination management. Tourism infrastructure has the lowest engagement value; therefore, in terms of promotion, it does not generate interest.
A Novel Machine Learning Approach for Blind Carrier Offset Estimation in OFDM Systems

As wireless networks continue to evolve with the emergence of sixth-generation networks and beyond, OFDM technology is expected to be an essential system component for providing reliable connectivity in an increasingly complex environment. Its high spectrum efficiency, efficiency against impulse noise, and resilience against frequency-selective multipath fading channels make it an invaluable component. Although OFDM technology has various capabilities and uses and is widely used, it has some issues and challenges, and one of these challenges is Carrier Frequency Offset (CFO). The CFO destroys orthogonality between subcarriers and causes subcarrier misalignment at the receiver, resulting in Inter- Carrier Interference (ICI) in OFDM systems. This interference impairs system performance by introducing errors and degrading signal-to-noise ratios (SNR). In this paper, a novel approach to estimate the CFO in OFDM systems via Feedforward Neural Network (FNN) has been proposed. The architecture is precisely designed for regression tasks, with a focus on accurately estimating the continuous parameter φ based on the input features. The multiple hidden layers facilitate the extraction of intricate patterns, while careful training options ensure efficient optimization and monitoring of the training process. The performance of the proposed FNN algorithm is assessed and compared with other subspace-based methods, ESPRIT, PM(MUSIC), and QR. Remarkably, the results demonstrate that the FNN algorithm consistently outperforms all subspace methods, especially in low SNR scenarios.

Published: July 2024

Research aims: This study aims to examine the factors that influence the quality of health information system (HIS) in hospitals in Bandung City and top management support as a moderating variable.
Design/Methodology/Approach: This research method is a survey. Eighty-three users of HIS in hospitals participated as respondents. Hypotheses were tested using the PLS-SEM method.
Research findings: The study results exhibited that software quality did not affect the health information system quality, even if it was moderated by top management support. While user competence significantly impacted health information system quality, top management support would strengthen the influence between user competence and health information system quality.
Theoretical contribution/Originality: This study presents a conceptual framework for HIS quality, with a specific emphasis on the role of top management support.
Practitioner/Policy implication: This study recommends that HIS should have interoperability. Additionally, there is a need for government policy support at both central and regional levels to ensure that the hospitals’ top management demonstrates a real commitment and contribution.

Microsatellite instability (MSI) and mismatch repair (MMR) deficiency are important biomarkers in colorectal cancer (CRC) that have clinical implications for patient management and treatment. MMR deficiency can lead to MSI, which is characterized by alterations in the length of microsatellite DNA sequences. Clinical applications of MMR deficiency in colorectal adenocarcinoma are as a prognostic marker as well as Predictive marker for adjuvant chemotherapy and immunotherapy.

To assess the MMR status of colorectal adenocarcinomas.

: This was a retrospective study of 127 colorectal adenocarcinomas cases. All the samples were either biopsies or surgically resected tumor tissues from patients of Carcinoma Colon and rectum. Immunohistochemistry was performed on Roche Ventana Benchmark XT autostainer.

: MLH-1, PMS2, MSH2 and MSH6 expression was retained in the tumor cells in 106 cases and it was lost in 21 cases. Among various clinicopathological variables, tumor site and AJCC pStage were found to be significantly associated with dMMR tumors.

Patients of colorectal adenocarcinomas were benefited by MMR testing as it influenced the adjuvant treatment in all Stage IIA cases as well as all metastatic cases. Incorporating MMR testing into routine clinical practice can help optimize patient management and treatment strategies in CRC.

Enhancing the technological capability accumulation process (TCAP) in firms is essential for Latin America's economic development. Yet, the dynamics between firms' characteristics and contextual factors that can help improve TCAP remain underexplored in the region. This study assesses the effects on TCAP of firm-level factors and national innovation systems (NISs)the network of institutions, policies, and relationships governing innovation within a country. Using data from the harmonized Latin American Innovation Surveys Database (LAIS) and a dataset to measure capabilities at the country level, we undertake a multilevel analysis for 20062016 to estimate the effects of NISs and firms structural characteristics on TCAP. Our results reveal that firm size, R&D capabilities, qualified personnel, and macro factors like national R&D investment and scientific output significantly drive TCAP. Conversely, factors such as corruption perception emerge as significant obstacles. These findings underline the complex interplay between innovation policies and firm capabilities, offering nuanced insights for policymakers to foster innovation in Latin America.
