Implementation of Graph Colouring Using Welch-Powell Algorithm to Determine Student Mentoring Schedule

Graph colouring using the Welch-Powell algorithm is one of the schedule preparation techniques. Especially for arranging student guidance schedules in a study program. The vertex on a graph is represented as a student who will conduct guidance, while the side that connects two vertex states if the two vertex or two students have one and/or two of the same supervisors. The results of this research indicate that the coloring of graphs using the Welch Powell algorithm can be applied to compile the guidance schedule of PGSD students at the Pacific University of Morotai

On the Locating Rainbow Connection Number of Trees and Regular Bipartite Graphs

Locating the rainbow connection number of graphs is a new mathematical concept that combines the concepts of the rainbow vertex coloring and the partition dimension. In this research, we determine the lower and upper bounds of the locating rainbow connection number of a graph and provide the characterization of graphs with the locating rainbow connection number equal to its upper and lower bounds to restrict the upper and lower bounds of the locating rainbow connection number of a graph. We also found the locating rainbow connection number of trees and regular bipartite graphs. The method used in this study is a deductive method that begins with a literature study related to relevant previous research concepts and results, making hypotheses, conducting proofs, and drawing conclusions. This research concludes that only path graphs with orders 2, 3, 4, and complete graphs have a locating rainbow connection number equal to 2 and the order of graph G, respectively. We also showed that the locating rainbow connection number of bipartite regular graphs is in the range of r-⌊n/4⌋+2 to n/2+1, and the locating rainbow connection number of a tree is determined based on the maximum number of pendants or the maximum number of internal vertices. Doi: 10.28991/ESJ-2023-07-04-016 Full Text: PD

Contenido de aceite en pasta de aceituna sobre una base de peso seco (OPDW): un indicador del tiempo de cosecha óptimo en modernos olivares

In modern oil olive orchards, mechanical harvesting technologies have significantly accelerated harvesting outputs, thereby allowing for careful planning of harvest timing. While optimizing harvest time may have profound effects on oil yield and quality, the necessary tools to precisely determine the best date are rather scarce. For instance, the commonly used indicator, the fruit ripening index, does not necessarily correlate with oil accumulation. Oil content per fruit fresh weight is strongly affected by fruit water content, making the ripening index an unreliable indicator. However, oil in the paste, calculated on a dry weight basis (OPDW), provides a reliable indication of oil accumulation in the fruit. In most cultivars tested here, OPDW never exceeded ca. 0.5 g.g–1 dry weight, making this threshold the best indicator for the completion of oil accumulation and its consequent reduction in quality thereafter. The rates of OPDW and changes in quality parameters strongly depend on local conditions, such as climate, tree water status and fruit load. We therefore propose a fast and easy method to determine and monitor the OPDW in a given orchard. The proposed method is a useful tool for the determination of optimal harvest timing, particularly in large plots under intensive cultivation practices, with the aim of increasing orchard revenues. The results of this research can be directly applied in olive orchards, especially in large-scale operations. By following the proposed method, individual plots can be harvested according to sharp thresholds of oil accumulation status and pre-determined oil quality parameters, thus effectively exploiting the potentials of oil yield and quality. The method can become a powerful tool for scheduling the harvest throughout the season, and at the same time forecasting the flow of olives to the olive mill.En los modernos olivares, las tecnologías de recogida mecánica han acelerado significativamente la recogida de las cosechas, lo que permite la planificación del momento idóneo de la cosecha. Mientras que la optimización de tiempo de cosecha puede tener importantes efectos en la producción de un aceite de calidad, las herramientas para determinar con precisión la mejor fecha de la cosecha son más bien pobres. Por ejemplo, el indicador de uso común, el índice de maduración de la fruta, no se correlaciona necesariamente con la acumulación de aceite. El contenido de aceite por peso de fruto fresco está estrechamente afectado por el contenido de agua de la fruta, por lo que es un indicador poco fiable. Sin embargo, el aceite en la pasta, calculado sobre una base de peso seco (OPDW), proporciona una indicación fiable de la acumulación de aceite en el fruto. En la mayoría de los cultivares analizados aquí, OPDW nunca excedió 0.5 g·g–1 de peso seco, haciendo de este umbral el mejor indicador para la terminación de la acumulación de aceite y su consiguiente reducción de la calidad. Las tasas de OPDW y los cambios en los parámetros de calidad dependen en gran medida de las condiciones locales, como el clima, el estado hídrico del árbol, y la carga frutal. Por tanto, proponemos un método rápido y fácil de determinar y seguir OPDW en un olivar determinado. El método propuesto es una herramienta útil para la determinación del momento óptimo de cosecha, especialmente en las grandes parcelas bajo prácticas intensivas de cultivo, y con el consiguiente aumento de ingresos. Los resultados de esta investigación pueden aplicarse directamente a un olivar, especialmente en operaciones a gran escala. Siguiendo el método propuesto, las parcelas individuales pueden cosecharse de acuerdo con los perfiles de estado de acumulación de aceite y determinados parámetros de calidad del aceite, por lo tanto explotar eficazmente los potenciales de rendimiento de aceite y calidad. El método puede convertirse en una poderosa herramienta de programar la cosecha a lo largo de la temporada, la previsión de este modo el flujo de las aceitunas a la almazara

Re-sequencing of the APOAI promoter region and the genetic association of the -75G > A polymorphism with increased cholesterol and low density lipoprotein levels among a sample of the Kuwaiti population

BACKGROUND: APOAI, a member of the APOAI/CIII/IV/V gene cluster on chromosome 11q23-24, encodes a major protein component of HDL that has been associated with serum lipid levels. The aim of this study was to determine the genetic association of polymorphisms in the APOAI promoter region with plasma lipid levels in a cohort of healthy Kuwaiti volunteers. METHODS: A 435 bp region of the APOAI promoter was analyzed by re-sequencing in 549 Kuwaiti samples. DNA was extracted from blood taken from 549 healthy Kuwaiti volunteers who had fasted for the previous 12 h. Univariate and multivariate analysis was used to determine allele association with serum lipid levels. RESULTS: The target sequence included a partial segment of the promoter region, 5’UTR and exon 1 located between nucleotides −141 to +294 upstream of the APOAI gene on chromosome 11. No novel single nucleotide polymorphisms (SNPs) were observed. The sequences obtained were deposited with the NCBI GenBank with accession number [GenBank: JX438706]. The allelic frequencies for the three SNPs were as follows: APOAI rs670G = 0.807; rs5069C = 0.964; rs1799837G = 0.997 and found to be in HWE. A significant association (p < 0.05) was observed for the APOAI rs670 polymorphism with increased serum LDL-C. Multivariate analysis showed that APOAI rs670 was an independent predictive factor when controlling for age, sex and BMI for both LDL-C (OR: 1.66, p = 0.014) and TC (OR: 1.77, p = 0.006) levels. CONCLUSION: This study is the first to report sequence analysis of the APOAI promoter in an Arab population. The unexpected positive association found between the APOAI rs670 polymorphism and increased levels of LDL-C and TC may be due to linkage disequilibrium with other polymorphisms in candidate and neighboring genes known to be associated with lipid metabolism and transport

This research is an experimental research which aims to determine the effectiveness of peer tutoring learning models with the use of LKS on student learning outcomes in solving the story problems in the material around and the area of ​​the circle. The population in this study were all eighth grade students of SMP Negeri 1 Kota Ternate and samples that were randomly taken were class VIIIA students as an experimental class which amounted to 27 students and class VIIIB as a control class totaling 30 students. Data collection is done through tests of student learning outcomes with 5 items as instruments that have been validated by the validator. The analysis of the data used is 5-scale PAP, homogeneity test, normality test, the Mann-Whitney test and hypothesis test. The results of the calculation of the initial homogeneity test obtained F count = 1.29 less than Ftable = 1.90, then the two data are homogeneous. In the normality test the final test data is obtained χ2 count&gt; tabel2 tables or 9.90&gt; 7.82 for the experimental class and χ2 count&gt; χ2 tables or 10.56&gt; 7.82 for the control class, meaning that the two group data are not normally distributed, so used non parametric statistical tests. The non parametric test used is the Mann-Whitney test, from the calculation results obtained by Zhitung = -4.14 with Ztable = ± 1.96 at a significant level () = 0.05, Accept H0 if -Zt ≤ ZH ≤ + Zt and Reject H0 if ZH&gt; Zt or ZH &lt;-Zt. Because ZH &lt;Zt (-4.14 &lt;-1,96), then H0 is rejected and H1 is accepted, meaning that there are differences in student learning outcomes between the experimental class and the control class in class VII students of SMP Negeri 1 Ternate City. Thus, there are differences in learning outcomes in class VIII students of SMP Negeri 1 Kota Ternate who use peer tutoring learning models with the use of LKS and those who do not use the learning model. Based on the mean, level of mastery obtained by the experimental class and the control class, as well as student activities and responses to peer tutoring learning models with the use of LKS, it can be concluded that the application of peer tutoring learning models with the use of effective LKS to improve student learning outcomes material around and area of ​​circl
