Abstract

Changes in land use/land cover (LULC) play a critical role in effective natural resource management, monitoring, and development, particularly within the realm of urban planning. In the examination of Tam Ky city, Quang Nam province, Vietnam, spanning from 2000 to 2020, remote sensing and Geographic Information System (GIS) techniques were employed. The Landsat satellite data (Landsat 7 ETM+ for 2000, Landsat 5 TM for 2010, and Landsat 8 OLI for 2022) underwent analysis using the supervised classification method in ArcGIS 10.8 software to identify and categorize six primary LULC classes: water bodies, agriculture, settlements, vegetation, construction, and bare soil/rocks. The reliability of the classification was evaluated through k values, revealing high accuracy with values of 0.951, 0.953, and 0.950 for the years 2000, 2010, and 2020, respectively. Notable shifts in LULC were observed during the period from 2000 to 2020. The areas covered by vegetation and settlements expanded by 53 and 1300 ha, respectively, while water bodies, agriculture, construction, and bare soil/rocks experienced reductions of 466, 48, 413, and 425 ha, respectively. To facilitate a rapid assessment, the study also incorporated the normalized difference vegetation index (NDVI) and normalized difference built-up index (NDBI). The trends identified in this study are consistently aligned with the results of the supervised classification. The identified changes in LULC pose a substantial environmental threat, and the study's outcomes serve as a valuable asset for future land use planning and management in the area. The method's high accuracy enhances the dependability of the results, making them crucial for well-informed decision-making and sustainable development initiatives.

Abstract

We developed and analysed a mathematical model to study the dynamics of an electoral process and predict the outcome in Nigeria with three political parties as major actors. We model the ruling party (P1); major opposition party (P2) and minority opposition parties (P3). The model includes party campaigners of the three political parties and a class of eligible voters. The model also incorporates the Independent National Electoral Commission (INEC), electoral observers, judiciary, security personnel and thugs. The influx of voters into the system is determined by the registration rate of voter cards. The model’s interest lies in the measure of positive influence that the party campaigners who eligible voters to join their party. With this, the model mirrors election’s outcome and the movement of voters between the three groups of political parties involved. The model has proven that the pattern of election’s outcome for each political party is affected by the defection of party members and lack of policy consistency. We determine the equilibria analytically and discuss the stability of the system. Numerical simulations are graphed in combination with curve fitting to compare each party’s performances over the years. The result shows that no political party remains in power steadily from 2007 to 2019. Thus, the prediction of elections outcome to the political space of any region in Nigeria depends on political party structures and voters’ decisions.

Abstract

Drymoglossum piloselloides is one of the epiphytic plants that is commonly found in Southeast Asia region. In this study, the ethanol extract of D. piloselloides plant has been used in the green synthesis of silver nanoparticles. The synthesized silver nanoparticles were characterized by ultraviolet-visible (UV-Vis) spectrophotometry, X-ray diffraction (XRD),Fourier-transform infrared (FTIR) spectroscopy, and transmission electron microscopy (TEM) measurements. The UV-Vis spectrum of silver nanoparticles showed a maximum wavelength at 453 nm. The XRD measurement showed the silver nanoparticles peaks at 38.38°, 44.60°, 64.76°, and 77.62°. The FTIR spectra provided evidence of the interaction between silver and chemicals in the plant extract as a weak signal at 682 cm-1. Meanwhile, TEM revealed an average size of 12.63nm. The synthesised silver nanoparticles were utilised for the reduction of 4-nitrophenol with a conversion percentage of up to 100% with a reduction reaction rate constant of 7.104 s-1. In addition, methylene blue was also successfully reduced with the synthesised silver nanoparticles as the catalyst with a reduction reaction rate constant (k) of 21.150 s-1. This study highlights the superior advantage of utilizing ethanolic extract of D. piloselloides to prepare silver nanoparticles with promising catalytic reduction purposes.

Abstract

The present study aimed at to establish typical dose reference level (DRL) values for adult patients undergoing computed tomography (CT) examinations in three hospitals in Brazzaville, Congo Republic. The examinations considered were head, chest, abdomen-pelvis, chest-abdomen-pelvis and lumbar spine CT scans. For each examination, the median of the distribution for the volume CT dose index (CTDIvol) and dose-length product (DLP) were determined. The median values were considered as the typical DRL values. Hypothesis testing was also carried out to statistically compare the mean values obtained for each participating CT facility. In the case of head scan, the typical values proposed in the present study in terms of CTDIvol and DLP were 15–48% and 28–60% lower than the DRL values reported in the literature, respectively. In the case of lumbar spine, the typical value determined in this study in terms of DLP was 48–70% greater than the DRL values provided in the literature. The typical values proposed for chest, abdomen-pelvis and chest-abdomen-pelvis were within the DRL values reported in the literature. It is possible that the adoption of the typical values proposed in the present study will help in reducing the dose received by adult patients undergoing CT examination in Congo Republic.

Abstract

In 2019, El Niño Southern Oscillation (ENSO) episodes in conjunction with climate change resulted in significant adverse impacts, particularly on developing nations. The year 2019 ranked among the top three warmest years since the mid-1800s. This paper aims to comprehensively analyze the El Niño period and the worsening climate trends observed in Mindanao, Philippines, during that year. The application of spatial analysis techniques revealed the existence of poverty hotspots characterized by below-average precipitation and enduring episodes of dangerous levels of heat index. The study documented instances of crop destruction and farmers' resulting problems. The application of multivariate clustering analysis revealed a significant association between urbanization and elevated mortality rates in climate-sensitive diseases. This finding suggests that the degree of urbanization has an apparent impact on regional mortality rates, ranging from modest to substantial increases. The findings underscore the necessity of implementing early warning systems and developing and implementing mitigation and adaptation methods. This is particularly crucial in sectors susceptible to adverse effects, such as agriculture and healthcare, where the immediate consequences are already observable.

Abstract

Katokkon chili (Capsicum annuum var. chinense) is a type of chili which are commonly found in Tana Toraja. It has a distinctive aroma, high spiciness, and a potential economic value but has not been widely identified and explored, thus, it is necessary to carry out molecular identification using DNA barcodes from chloroplast DNA. The aim of this study was to determine genetic variation and the results of constructing a phylogenetic tree from DNA sequences katokkon chili (C. annuum var. chinense) using the rbcL marker. This study used 6 samples of katokkon chilies (C. annuum var. chinense) and 3 outgroup samples (C. frutescens, C. chinense and C. baccatum). The stages of the research included total DNA isolation, qualitative and quantitative tests, PCR amplification using rbcL primers, and sequencing. Data analysis used is sequence alignment, phylogenetic, genetic distance matrix, haplotypes and phylogeography. The results showed genetic variation with 7 polymorphisms consisting of 4 singleton sites at the nucleotide base sequences of 6th, 525, 715 and 737, and 3 parsimony informative sites at the nucleotide base sequences 370, 616 and 902 and the haplotype distribution is divided into 4 haplotypes namely Hap_1 (A1, A2, A3, B1, B2 and B3), Hap_2 (C1), Hap_3 (C2), and Hap_3 (C3). The phylogenetic tree construction formed two clades, namely clade I consist of six samples of katokkon chilies (C. annuum var. chinense) and clade II consisting of three outgroup samples. Mark the highest bootstrap is 96 and the lowest bootstrap value is 29. Genetic distance matrix values are in the range of 0.000–0.005.
