Published: August 2024

Subsurface modeling based on density variations is currently developing very rapidly. This modeling can be achieved using a computational technique called inversion modeling for mathematical calculations on gravity data. The objectives of this research are to create a 2D sparse inversion algorithm for gravity data using SimPEG, which is then interpreted to analyze geothermal fields. The method research begins with a synthetic data study that includes spectrum analysis and synthetic data inversion using vertical, horizontal, and fracture block models. In terms of synthetic data inversion results, the sparse inversion algorithm is considered quite good, with an average root mean square error (RMSe) of 0.551 mGal and a correlation of 69.81%. Furthermore, the sparse inversion algorithm was used to invert the Ungaran Volcano field data, obtaining results with an RMSe value of 0.087 mGal. The model produced using the sparse inversion method was considered to correlate well with the geological information and models in previous research. In this paper, we present a new approach to inversion modeling techniques that are available in the SimPEG library with the Python programing language and can be applied to geothermal fields.

Cellulose is one of the most abundant biopolymers on Earth and is of most significant interest due to its properties and uses. Cellulose can be obtained from agro-industrial residues, such as rice husk, whose cellulose content is approximately 30%. In this study, cellulose microfibers were extracted from rice husks. Fibers were obtained by submitting the biomass to alkali (NaOH) and bleaching treatments. These treatments have already been reported in the literature; however, variables such as the concentration of reagents, the time, and the temperature of the chemical treatment have yet to be optimized. A factorial design of experiments with 3 factors and 2 levels for each factor was proposed to optimize the chemical processes. It was determined through the analysis of variance (ANOVA) that the factors evaluated significantly influenced the elimination of non-cellulosic compounds, and that the chemical treatment was more efficient when the factors took high level values. Ultraviolet-visible spectroscopy (UV-Vis) analysis showed the successful removal of undesired components during the alkaline treatment. The effect of the treatments on the morphology upon removing hemicelluloses, lignin, and inorganic material was evaluated through Scanning Electron Microscopy (SEM). The increase in the thermal stability in the alkali-treated rice husk and in cellulose microfibers, compared to the raw rice husk, was established by thermogravimetric analysis (TGA). X-ray diffraction (XRD) indicated that the treatments increased the percentage of crystallinity.

Cellulose derivative products, such as carboxymethyl cellulose (CMC), which are used in the food, cosmetics, and pharmaceutical industries, but still rely on cotton-derived cellulose, can be made from oil palm fruit empty bunches (OPEFB) and rice straw. This study examined how sodium monochloroacetic acid (NaMCA) concentration (3, 6, and 9 g) affected the simple synthesis and characteristics of CMC from OPEFB and rice straw cellulose. OPEFB-derived CMC produced with NaMCA (9 g) had the lowest of brightness, while rice straw CMC was brighter. NaMCA modifications altered the onset temperature (Tonset), but not maximum degradation temperature (Tmax), according to thermal analysis. The onset temperatures of OPEFB and rice straw CMC were 40–62 °C and 67–183 °C, respectively. Commercial CMC has an onset temperature of about 27 °C. The EDX analysis showed that rice straw CMC had a higher degree of substitution (DS) of 0.34–1.37 than OPEFB CMC, which had 0.30-0.70. Oil palm empty fruit bunch (OPEFB) cellulose and rice straw cellulose offer a viable carboxymethyl cellulose (CMC) alternative. This process turns agricultural waste into valuable products and enables for their usage in numerous applications.

This study reported the isolation of cellulose from corn cob by using microwave-assisted alkaline treatment and bleaching. The Central Composite Design (CCD) approach of Response Surface Methodology (RSM) was applied to study the effect of sodium hydroxide (NaOH) concentrations (1.5-2.5M), duration of alkaline treatment (4-8 min), hydrogen peroxide (H2O2) concentrations (7-9 wt%) and bleaching time (3-7 min) on the removal percent of non-cellulosic components and impurities from corn cob. The optimized conditions obtained from this study were 2.37M NaOH, 9 wt% H2O2, alkaline treatment time of 4 min, and bleaching time – 4.20 min. The non-cellulosic part and the impurities removed under the optimized conditions in microwave-assisted alkaline treatment and bleaching amounted to 72.26 ± 0.15%. The cellulose content in the thus purified corn cob material was determined as 92.47%. The isolated corn cob cellulose was characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), and the thermogravimetric analysis (TGA). These characterizations confirmed that the alkaline treatment and microwave-assisted bleaching under the optimized conditions achieved the optimal removal percent of the non-cellulosic components and impurities from the corn cob biomass to achieve highly purified cellulose.

Valorization of lignin in biorefineries is important as this can lead to enhancement of chemical and physical properties of lignin, making it suitable for applications in polymers, composites and adhesives. Lignin valorization requires overcoming recalcitrance and tailoring for different uses. Here, lignin was extracted from rice straw lignin-rich residue at pH 12, using 4% magnesium oxide and 6% sodium hydroxide on a dry w/w basis. The extracted lignin-rich stream, which had a pH in the range of 9-10, was used further for biochemical transformation. Towards that end, Pseudomonas putida, Sphingomonas paucimobilis, Pseudomonas fluorescens and Bacillus tequilensis were screened for their capability of aromatic dye decolourization. The results of the study show an increase in the total phenolic content in lignin between 50% and 55% after 144 h of treatment with Pseudomonas putida. Concomitant with the increase of phenolics, a four-fold increase in antioxidant activity in gallic acid equivalents was also observed when Pseudomonas putida was used.

Copper oxide nanoparticles (CuO NPs) were synthesized using mucilage from the seeds of Mimosa pudica. Fully characterized CuO NPs using different spectroscopic techniques, such as UV-Vis, XRD, SEM, and FTIR, were evaluated as catalysts for the photodegradation of methyl orange and methylene blue. The UV-Vis analysis displayed an intense surface plasmon resonance at 273 nm, indicating the formation of CuO NPs. The functional groups in the mucilage and synthesized CuO NPs were examined by FTIR spectroscopy, and a peak at 475 cm-1 established the successful synthesis of CuO NPs. The morphology of the CuO NPs was observed by SEM analysis, revealing spherical CuO NPs embedded in the mucilage. The crystalline nature of CuO NPs was confirmed by XRD analysis, which showed a mean crystallite size of 29 nm. Furthermore, following pseudo-first-order kinetics, CuO NPs degraded methylene blue (89.47%) more effectively than methyl orange (79.25%) under sunlight. The reusability of CuO NPs was studied, and, after 4 cycles, CuO NPs indicated excellent photocatalytic performance with minor decrease in efficiency.

We report the use of a low-thermal-budget annealing technique; flash lamp annealing (FLA), which provides an extremely short annealing time in the millisecond range, on the ferroelectric properties of Al-doped HfO2 (HAO) films. HAO annealed at 1000 °C with 5 ms shows a higher remanent polarization value of 24.9 μC cm−2 compared to rapid thermal annealing (RTA), without degradation of endurance. GIXRD shows a stronger peak intensity originating from the orthorhombic (o-) phase and is observed when using FLA, indicating the formation of a larger amount of the o-phase. We believe that this is a consequence of the low thermal budget of FLA, and that specifically FLA can minimize the relaxation of the compressive stress in the TiN electrodes, inducing a high tensile stress to the HAO films and therefore an enhancement of o-phase formation. These results indicate that FLA is a promising annealing method for HAO crystallization due to the enhancement of o-phase formation.

The strong coupling of charge carriers with molecular vibrations is one essential characteristic of organic semiconductor materials as molecular solids. To address this question, fundamental solid-state properties of each molecular species are demanded not only for the electronic states but also for the vibrational characteristics. In the present study, Fourier-transform infrared absorption measurements were performed on single-crystal samples of dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene (DNTT) by using a linearly polarized synchrotron radiation light source. Molecular vibrational modes in a wavenumber range of 200–1600 cm−1 were reasonably assigned, and the Davydov splittings of several vibrational modes were resolved demonstrating intermolecular couplings of two DNTT molecules in the unit cell.

Published: August 2024

Due to the drastic growth, the Internet of Things (IoT) has become an inevitable form of human life. However, IoT communication is subjected to a vast range of security breaches in the vulnerable environment, which leads to the demand for appropriate technology security issues in IoT communication. The cryptography technique exhibits effective security characteristics that promise promising results for identifying security breaches in IoT. This paper proposes attribute-based elliptical curve cryptography (ATB_ECC) to improve security in IoT communication. IoT devices perform communication to overcome security issues in IoT based on defined attributes of access points. Attributes are involved in the characteristics of trusted nodes in the network. The cryptography technique utilizes Elliptical Curve Cryptography (ECC) to transmit messages securely in the IoT environment. Through integrating attribute factors and cryptography techniques, the IoT network can distinguish variations in the active data communication and threats in the IoT network. Simulation performance is examined for different critical structures, such as low, medium, and high. The proposed ATB_ECC is examined for attack prediction scenarios considering real-time servers. The examined results stated that the proposed ATB_ECC has effectively prevented attacks, especially brute force attacks. Analysis of results stated that low-key structure exhibits minimal complexity, but the security level is minimal. A high-key structure consumes vast energy and has increased complexity, but the security is significantly improved. The comparative analysis of various key structure results illustrated that the proposed attributes-based ECC exhibits improved performance at 15% for throughput.

Methodology: Planned and structured counseling sessions were conducted by lecturers and students, accompanied by simple laboratory tests for the Adainasnosen village community, including the examination parameters of Blood Pressure (BP), Uric Acid, Hemoglobin (Hb), Cholesterol, and Blood Sugar.
Results: Some members of the village community were found to need an immediate change in lifestyle towards a healthier direction because several laboratory examination parameters were above normal levels. Regular counseling and examinations related to Non-Communicable Diseases (NCDs) must be implemented to effectively and comprehensively prevent these diseases.
Limitations: Tools and materials fundamental for counseling inspections are limited. Hopefully, in the future, better inspection tools with a larger quantity can be utilized, enabling outreach to a greater number of village communities.

Evaluation of secondary school geography teachers’ pedagogical practices in Southwestern Nigeria
Authors: Olayemi Andrew A. , Amosun Peter A.
Published: August 2024

Purpose: This study was conducted to evaluate teachers’ pedagogical practices in secondary schools in southwestern Nigeria because evidence has shown that some of the objectives of the geography curriculum are hardly met. Research interest has been more on interventions, especially strategies to improve students’ learning outcomes in geography, than on the evaluation of implementation.
Research methodology: A mixed-methods design was adopted. Three states (Osun, Oyo, and Ekiti) in southwestern Nigeria were randomly selected, and the purposive sampling technique was used to select schools with a geography teacher who was willing to participate in the study.
Results: Most teachers (67.1%) deployed the lecture method, while schools (84.6%) had insufficient time to implement GC. Inadequate materials (84.1%), limited opportunities for professional development (89.4%), and insufficient allocated time (78.7%) were the major challenges associated with the implementation of GC. The pedagogical practices were good (????? = 3.40), but material resources were inadequate (????? 0.83), 3.4 against the threshold of 3.0 and 1.0, respectively.
Contribution: Teachers rarely used the field-trip approach. The teachers posited that they had inadequate resources for implementation. School administrators should ensure that geography is allotted sufficient time to the timetable.
Limitations: The observer effect may have slightly influenced the classroom activities of some teachers and students. Similarly, not all items on the rating scale could be captured extensively within the observed teaching-learning period.
Novelty: Although the goals of sustainable development place a special emphasis on healthy and prosperous lives, insufficient data on mental health have been collected, and mental health policies based on village wisdom have not become a theme that many central and regional governments have implemented.

Background: Renal dysfunction is a common complication in patients with liver cirrhosis, with hepatorenal syndrome (HRS) being the most severe form. HRS is characterized by disturbances in both circulatory and kidney functions and is diagnosed by excluding other causes of renal failure. Objective: This study aimed to measure the renal artery resistive index (RI) in non-azotaemic cirrhotic patients with ascites to predict early renal haemodynamic dysfunction. Methodology: A prospective study was conducted involving 30 cirrhotic patients with ascites and 15 healthy controls. Renal artery RI was measured using Duplex Doppler ultrasonography. Inclusion criteria for patients included normal renal function, as indicated by serum creatinine ≤ 1.2 mg/dl and creatinine clearance rate ≥ 50 ml/min. Results: The mean renal artery RI was significantly higher in cirrhotic patients with ascites (70% had RI ≥ 0.70) compared to controls (all had RI < 0.70). Significant differences were observed in serum bilirubin, SGPT, SGOT, and prothrombin time between cases and controls (p < 0.05). Conclusion: Renal Doppler ultrasonography is a valuable noninvasive method for detecting early renal haemodynamic dysfunction in cirrhotic patients with ascites. Elevated renal artery RI can serve as an indicator of renal dysfunction, aiding in early diagnosis and management.
