Published: August 2023

El triclosán (TCS) es un químico antibacteriano que se usa como ingrediente común en productos relacionados con el cuidado de la salud y el hogar. Los consumidores están expuestos a estos productos. Se utilizó el software Hyperchem para realizar todos los cálculos cuánticos. Se eligió el método semiempírico de PM3 (SE-PM3). La energía mínima se calculó utilizando el teorema de Richard Feynman y el algoritmo de Polak-Rebiere. Los cálculos específicos de HOMO, LUMO y la densidad de electrones, el ancho de banda y el coeficiente de transferencia de electrones (CTE) se realizaron interacción por interacción. El TCS está ubicado en la interacción más alta del pozo cuántico. Esta interacción es la más débil y la menos similar de todas. En las interacciones oxidación-reducción se observa el poder oxidante del TCS. Esta interpretación nos lleva a predecir que el TCS ataca a los aminoácidos con mayor afinidad química y probabilidad de forma oxidativa (destructiva), pero no así a las bases nitrogenadas. Las interacciones de TCS con BNs nos llevan a concluir que es poco probable que esta sustancia cause mutaciones de ADN y ARN.

The application of polyurethane waste as a filler is one of the most cost-effective strategies for enhancing the geotechnical properties in soils. The PU waste from manufacturing economies was prepared with alkaline solutions by submerging into a 0.05 M sodium hydroxide (NaOH) before sieving to 300m sizes. The PU waste as filler was prepared using two heat exposure from microwaves and drying ovens at 60°C and left for 3 hours. Then, the treated and untreated Polyurethane-Clay Composite (PU-CC) was prepared at the different ratios of PU waste filler (2.5%, 5%, 7.5%, and 10%). The physical properties of treated and untreated Polyurethane-Clay Composite (PU-CC) were examined utilizing buoyancy force, unconfined compressive strength (UCS), and direct shear strength, respectively. The result exhibited that the PU-CCTO has the highest buoyancy force at 10% of PU-CCTO10 samples at 50%, followed by 45% of PU-CCTM10 and 8% of PU-CCUN2.5. The UCS and shear strength of PU-CCTO10 are evidently the highest at 300 kPa and 50 kPa, respectively, followed by PU-CCTM2.5 at 130 kPa and 19 kPa and PU-CCUN2.5 at 100 kPa and 15 kPa. PU-CCTO treated by drying oven has the highest buoyancy force at 10% of PU-CCTO10 samples at 50%, followed by 45% of PU-CCTM10 treated by microwave, and the lowest at 2.5 wt% of PU-CCUN2.5 untreated at 8%. In a nutshell, the prospective PU-CCTO is superior to the PU-CCUN and PU-CCTM related of the potential for overheating and burning the PU filler powder during the microwave processing procedure. In conclusion, the 10 wt% of PU filler treated by the drying oven method as a PU clay composite has the potential as an alternative material to improve the compressive strength, shear strength, and buoyancy force in soil improvement.

Published: August 2023

Organic food waste management has been a major issue for the environment, as it poses a significant threat to human health and the ecosystem. Converting this waste into a valuable resource is crucial for sustainable development. In this project, we aim to develop a microbial fuel cell (MFC) using leftover rice as a substrate, which can generate electricity through the electrochemical reactions of microorganisms. The main objectives of this study are to investigate the performance of MFCs under two different conditions: with and without a mediator and catalyst. The experimental results showed that both designs of MFCs achieved optimized outputs, with a minimum of 5V voltage output. This demonstrates the potential of MFCs as a promising alternative renewable energy source. MFCs can be utilized as a sustainable energy source, particularly for rural areas, where access to electricity is limited. Furthermore, large-scale operation of MFCs can significantly reduce food waste, which has a significant impact on health and the environment. By converting food waste into electricity, this technology can help mitigate the negative effects of waste accumulation and contribute to the transition towards a circular economy.

The objective of this research is to optimize fish growth in super-intensive aquaculture systems by addressing water quality issues. Changes in water parameters can significantly impact fish growth and even lead to mortality. To overcome this problem, real-time monitoring of water quality parameters is crucial, and the data should be automatically transmitted to the entrepreneur through the Internet of Things (IoT). This allows the owner to access real-time data remotely, eliminating the need to be physically present at the fish cage. By monitoring the data on a smartphone, the owner can efficiently manage the water quality. In this study, a water quality monitoring system utilizing temperature, pH, and ESP32, with the parameter values displayed on the Blynk platform was developed. The system successfully measures real-time water conditions and transmits the data to the Blynk application. The test results demonstrate the system's capability to receive and send data, but further analysis is needed to evaluate the accuracy and reliability of the measurements and identify any noteworthy findings.

Published: August 2023

In our cutting-edge environment, a lightweight organic brick is an optional revelation item that should be taken into consideration. The organic brick is superior to the traditional brick in terms of additional qualities. During assembly, it can reduce the exemplified energy of regular brick. Utilizing this organic brick could result in greater energy savings from a warm comfort perspective and help to protect the environment because it produces less pollution. The unused rice husks that are piling up in Perlis give rise to this item as a potential solution to the problem. In light of this idea, leftover rice husks can be used to create organic brick. In addition, Malaysia's rapid development would subsequently build the block requests. This fuels the primary objective of researching renewable and environmentally friendly alternatives to conventional brick. Since it is eco-friendly and easily obtainable in Malaysia, rice husk stands out among other optional lightweight options. By baking clay, rice husk, and cement together, lightweight organic brick is produced. The organic sample, which contains up to 80% rice husk, is added and put through an oven drying process so that it can dry entirely before the testing can begin. Because there was more rice husk in the specimen, there were more pores, which enhanced the compressive strength. As a result, the quality of the rice husk increases as more of it is added. Although the organic brick specimen doesn't meet the standard for compressive strength, it does so for low bulk density, which is much lower than the requirement for lightweight materials. It is therefore perfectly reasonable to use it as a light construction material.

Published: August 2023

An extraordinary worldwide shift is occurring in the twenty-first century, as people increasingly turn to renewable energy sources. However, hybrid renewable energy system (HRES) development in rural regions is technically difficult and financially expensive to provide energy access. Due to the various components necessary to produce a hybrid system, its construction is often costly. As the remote areas depend on unsustainable diesel-fuelled generators, they have greater operational expenses than non-remote areas due to the higher cost of diesel and the longer distances needed to transport the fuel. This work focuses on modelling a hybrid renewable energy system that is economically sustainable, environmentally friendly and technical consideration is taken into the design requirements. The energy cost ($/kWh) and lifecycle emission CO2 (kg/year) are considered as economic and environmental indicators, respectively. In addition, a sensitivity analysis for varied diesel fuel price ($/L) and PV capital cost of the HRES is performed to achieve a more feasible configuration. To obtain a system that can fulfil demand while meeting specific technical requirements, three configurations are evaluated: 1) standalone diesel generators, 2) hybrid PV-Diesel without battery and 3) hybrid PV-Diesel with battery. This study proposed system 3 as the best system architecture due to the lowest value of COE of 0.258$/kWh and NPC of $22,130. A solar photovoltaic (PV) and lead acid (LA) battery-based hybrid renewable energy system is suggested to fulfil the camp facility load demand of 14.92kWh/day in a rural area of Sungai Tiang, Perak. Sensitivity analysis findings show that LCOE and NPC values are substantially responsive to fuel price and PV capital cost. Integrated solar and battery technologies can enhance the economic performance (e.g., NPC, COE), environmental performance (e.g., carbon dioxide emissions), and technical performance (e.g., fuel consumption) of a renewable energy system.
Covid-19, racism and the ‘state of exception’? A theological ethical engagement with identity and human rights in an age of ‘Corona’ and beyond
Authors: Forster D.
Published: August 2023

The COVID-19 pandemic highlighted the role that religion and politics play at the intersection with individual and social rights. Religiously informed political actors capitalised on fears and prejudices to further science denialism, normalise nationalist ideologies, and curtail human rights. In the United States of America, Brazil, and South Africa, it took the form of problematic political theologies. In many instances, a state of exception, as understood in the work of Giorgio Agamben, was enacted. Such actions often have biopolitical significance revolving around making political choices informed by religious beliefs that impact on individual bodies and social freedoms. This extends from individual bodies tosocieties. This research employs a qualitative literature approach to investigate the intersection of political and theological beliefs during the pandemic. It highlights the impact of populist political theologies on the erosion of democracy and human rights in countries that have highly religious populations. It is argued that these strategies reach beyond the COVID-19 pandemic.

Evolution of South African brambles (Rubus L.) – new insights from molecular markers
Authors: Sochor Michal , Manning John
Published: August 2023

Background: South African brambles (Rubus L., Rosaceae) represent a complex group of six native species and at least 12 introduced taxa with different ploidy levels and varying tendencies to hybridisation. The role of hybridisation, introgression and apomixis in the ongoing evolution has been hypothesised based on morphological observations, but it has not been rigorously studied to date, and nor has the phylogeny of the group.
Objectives and methods: This paper aims to reveal the evolutionary patterns and mechanisms in South African brambles by employing three types of molecular markers: plastid and nuclear ribosomal DNA sequences, and nuclear microsatellites.
Results: The data confirmed the tetraploid R. thaumasius A.Beek and diploid R. ludwigii Eckl. & Zeyh. as distinct native species, while the other four native species are shown to be closely related and likely derived from three ancestors.
Conclusion: Ancient hybridisation and limited gene flow between regions (particularly between winter- and summer-rainfall zones) appear to be the main drivers of current patterns in the tetraploid R. pinnatus Willd. and hexaploid R. rigidus Sm. Current hybridisation is also likely, although rare. The mechanism of ‘octoploid bridge’ is proposed, which overcomes the ploidy reproduction barrier between R. pinnatus (or other tetraploids) and R. rigidus. No gene flow was detected between native and alien taxa, but clonal duplications were discovered in the R. bergii × pinnatus hybrid, which implies the possibility of apomictic spread of homoploid hybrids formed between native and introduced brambles and the potential for a new invasion. On the other hand, heteroploid hybrids (R. bergii × rigidus) are formed recurrently and spread only vegetatively.
Rovibrational Spectroscopy of CI Tau—Evidence of a Multicomponent Eccentric Disk Induced by a Planet

Published: August 2023

CI Tau is currently the only T Tauri star with an inner protoplanetary disk that hosts a planet, CI Tau b, that has been detected by a radial velocity survey. This provides the unique opportunity to study disk features that were imprinted by that planet. We present multiepoch spectroscopic data, taken with NASA IRTF in 2022, of the 12CO and hydrogen Pfβ line emissions spanning nine consecutive nights, which is the proposed orbital period of CI Tau b. We find that the star’s accretion rate varied according to that nine-day period, indicative of companion-driven accretion. Analysis of the 12CO emission lines reveals that the disk can be described with an inner and an outer component spanning orbital radii 0.05–0.13 au and 0.15–1.5 au, respectively. Both components have eccentricities of about 0.05 and arguments of periapsis that are oppositely aligned. We present a proof-of-concept hydrodynamic simulation that shows that a massive companion on a similarly eccentric orbit can recreate a similar disk structure. Our results allude to such a companion being located at an orbital distance of around 0.14 au. However, this planet’s orbital parameters may be inconsistent with those of CI Tau b, whose high eccentricity is likely not compatible with the low disk eccentricities inferred by our model.
Particle Energization at a High Mach Number Perpendicular Shock: 1D Particle-in-cell Simulations
Authors: Hao Yufei , Yang Zhongwei , Guo Fan , Liu Terry Z. , Kong Xiangliang , Shan Lican , Wu Dejin
Published: August 2023

In this paper, we use a 1D particle-in-cell simulation code to study particle preaccelerations at a high Mach number perpendicular shock. Our simulation results show that almost all of the injected particles can be reflected at the shock front, and then they immediately gyrate back to upstream for a long distance. That facilitates the formation of a large-scale shock foot where they dominate the average velocity of particles and the formation of resultant electric fields with several subareas, unlike a low Mach number shock with fewer reflected particles. In the large-scale shock foot with subareas, these reflected particles can be energized by the motional electric fields and unexpected electrostatic fields, which means they may undergo multiple stages of preacceleration processes when gyrating just before the high Mach number perpendicular shock front with high-intensity particle reflection.
Evidence of a Massive Stellar Disruption in the X-Ray Spectrum of ASASSN-14li

Published: August 2023

The proximity and duration of the tidal disruption event ASASSN-14li led to the discovery of narrow, blueshifted absorption lines in X-rays and UV. The gas seen in X-ray absorption is consistent with bound material close to the apocenter of elliptical orbital paths, or with a disk wind similar to those seen in Seyfert-1 active galactic nuclei. We present a new analysis of the deepest high-resolution XMM-Newton and Chandra spectra of ASASSN-14li. Driven by the relative strengths of He-like and H-like charge states, the data require [N/C] ≥ 2.4, in qualitative agreement with UV spectral results. Flows of the kind seen in the X-ray spectrum of ASASSN-14li were not clearly predicted in simulations of TDEs; this left open the possibility that the observed absorption might be tied to gas released in prior active galactic nucleus (AGN) activity. However, the abundance pattern revealed in this analysis points to a single star rather than a standard AGN accretion flow comprised of myriad gas contributions. The simplest explanation of the data is likely that a moderately massive star (M ≳ 3 M
⊙) with significant CNO processing was disrupted. An alternative explanation is that a lower mass star was disrupted that had previously been stripped of its envelope. We discuss the strengths and limitations of our analysis and these interpretations.

Published: August 2023

The detached trans-Neptunian objects (TNOs) are those with semimajor axes beyond the 2:1 resonance with Neptune that are neither resonant nor scattering. Using the detached sample from the Outer Solar System Origins Survey (OSSOS) telescopic survey, we produce the first studies of their orbital distribution based on matching the orbits and numbers of the known TNOs after accounting for survey biases. We show that the detached TNO perihelion (q) distribution cannot be uniform but is instead better matched by two uniform components with a break near q ≈ 40 au. We produce parametric two-component models that are not rejectable by the OSSOS data set and estimate that there are 36,000

< 8.66 (D ≳ 100 km) and semimajor axes 48 au < a < 250 au (95% confidence limits). Although we believe that these heuristic two-parameter models yield a correct population estimate, we then use the same methods to show that the perihelion distribution of a detached disk created by a simulated rogue planet matches the q distribution even better, suggesting that the temporary presence of other planets in the early solar system is a promising model to create today’s large semimajor axis TNO population. This cosmogonic simulation results in a detached TNO population estimate of 48,000

. Because this illustrates how difficult-to-detect q > 50 au objects are likely present, we conclude that there are (5 ± 2) × 104 dynamically detached TNOs, roughly twice as many as in the entire trans-Neptunian hot main belt.
Regolith Inhibits Salt and Ice Crystallization in Mg(ClO4)2 Brine, Implying More Persistent and Potentially Habitable Brines on Mars
Authors: Shumway Andrew O. , Catling David C. , Toner Jonathan D.
Published: August 2023

On Mars, liquid water may form in regolith when perchlorate salts absorb water vapor and dissolve into brine, or when ice-salt mixtures reach their melting temperature and thaw. Brines created in this way can chemically react with minerals, alter the mechanical properties of regolith, mobilize salts in the soil, and potentially create habitable environments. Although Martian brines would exist in contact with regolith, few studies have investigated how regolith alters the formation and stability of brines at Mars-relevant conditions. To fill this gap, we studied magnesium perchlorate brine in a Martian regolith simulant at salt concentrations up to 5.8 wt.%. We measured the water mass fraction and water activity between 3 and 98% relative humidity at 25 °C using the isopiestic method, and monitored salt and ice crystallization between −150 °C and 20 °C with differential scanning calorimetry. Results show that regolith inhibits salt and ice crystallization, allowing water to form and persist at much colder and drier conditions than pure brine. Remarkably, in several samples, neither salt nor ice crystallized at any conditions. These results suggest that brines could exist in regolith for longer periods of the Martian year than previously thought, and could persist indefinitely under certain conditions. By retaining water, inhibiting salt and ice crystallization, and maintaining habitable water activity, briny regolith may be a more favorable environment for life than pure brine alone. These findings indicate the critical importance of brine–regolith interactions for understanding the properties, evolution, and potential habitability of Mars’s surface.

Published: August 2023

A new form of basis functions structures has been constructed. These basis functions constitute a mix of Chebyshev polynomials and Legendre polynomials. The main purpose of these structures is to present several forms of differentiation matrices. These matrices were built from the perspective of pseudospectral approximation. Also, an investigation of the error analysis for the proposed expansion has been done. Then, we showed the presented matrices' efficiency and accuracy with several test functions. Consequently, the correctness of our matrices is demonstrated by solving ordinary differential equations and some initial boundary value problems. Finally, some comparisons between the presented approximations, exact solutions, and other methods ensured the efficiency and accuracy of the proposed matrices.
Fractional Timoshenko beam with a viscoelastically damped rotational component
Authors: Al-Homidan Banan , Tatar Nasser-eddine
Published: August 2023

This paper is concerned with a fractional Timoshenko system of order between one and two. We address the question of well-posedness in an appropriate space when the rotational component is viscoelastic or subject to a viscoelastic controller. To this end we use the notion of alpha-resolvent. Moreover, we prove that the memory term alone may stabilize the system in a Mittag-Leffler fashion. The system is Lyapunov stable or uniformly stable in the case of different speeds of propagation.
The moment exponential stability of infinite-dimensional linear stochastic switched systems
Authors: Zheng Guojie , Wang Taige
Published: August 2023

This paper studies the 2nd-moment exponential stability of a class of infinite-dimensional linear stochastic switched systems comprising two unstable subsystems. We first construct an algebraic sufficient condition on the existence of multiple Lyapunov functions. Then, two switching strategies are designed to stabilize infinite-dimensional linear stochastic switched systems in terms of the multiple Lyapunov function method. Moreover, the system possesses good robust stability of the switching time with our switching strategies.
Two-level QR code scheme based on region matrix image secret sharing algorithm

Published: August 2023

Quick response (QR) codes have become increasingly popular as a medium for quickly and easily accessing information through mobile devices. However, the open-source nature of QR code encoding poses a risk of information leakage and potential attacks, especially with the growing use of QR codes in financial services and authentication applications. To mitigate the risk of information leakage due to open-source QR code encoding, this paper proposes a two-level QR code scheme based on a region matrix image secret sharing algorithm. In this scheme, the first-level public information can be directly obtained by scanning with any standard QR code scanner, while the two-level secret information can only be accessed by overlaying the shared images. To enhance the robustness of joint secret information recovery using shared images, this article designs a progressive image secret sharing algorithm based on region matrices. This algorithm meticulously processes high-priority share regions and generates multiple substitute shares. In the event of attacks on key shares, substitute shares can be employed to recover the secret information. For an increased payload capacity of each QR code, an adaptive pixel depth adjustment algorithm is devised. This algorithm ensures that the recovery of two-level secret information maintains high clarity, while not affecting the scanning functionality of each shared QR code. Experimental results validate the feasibility of this scheme, which simplifies the construction matrix, reduces matrix redundancy, and exhibits priority partitioning and higher robustness. Furthermore, QR codes embedding secret shares can safeguard the two-level information, and the recovered images exhibit exceptional clarity.
Heterogeneous Convolutional Neural Networks for Emotion Recognition Combined with Multimodal Factorised Bilinear Pooling and Mobile Application Recommendation
Authors: D. Saisanthiya  , P. Supraja
Published: August 2023

The field of emotion recognition has garnered considerable interest due to its diverse applications in mental health, personalised advertising and enhancing user experiences. This research paper introduces a unique and innovative method for emotion recognition by integrating heterogeneous convolutional neural networks (CNNs) with multimodal factorised bilinear pooling. Furthermore, the paper also incorporates the integration of mobile application recommendations as part of the overall approach. The proposed method leverages the power of CNNs to extract high-level features from different modalities, including facial expressions, speech signals and physiological signals. By using heterogeneous CNNs, each modality is processed independently to capture modality-specific emotional cues effectively. To fuse the extracted features, multimodal factorised bilinear pooling is employed, which captures the complex interactions between different modalities while reducing the computational complexity. This pooling technique efficiently combines the modality-specific features, resulting in a compact and discriminative representation of the emotional state. In addition to emotion recognition, this paper also introduces the integration of mobile app recommendations. By leveraging the recognised emotion, the system recommends relevant mobile applications that are tailored to the user’s emotional state. This integration enhances user experience and facilitates emotion regulation through the utilisation of appropriate mobile apps. Experimental evaluations are conducted on benchmark emotion recognition datasets, including the DEAP and MAHNOB_HCI datasets. The findings of the study highlight the effectiveness of the proposed methodology in terms of accuracy and robustness, surpassing existing approaches in the field. Additionally, the integration of the mobile app recommendation system showcases encouraging outcomes by offering personalised recommendations tailored to the user’s emotional state.
