Kemampuan representasi matematis siswa pada materi bilangan berdasarkan self-confidence
Authors: Ulfa Nabilah Citra Amalia , Sundayana Rostina 
Published: July 2024

The low ability of students’ mathematical representation has an effect on achievement in mathematics learning. Students find it difficult to understand what is known and asked, also are still not able to find a way out in solving the questions so that many students find it difficult to solve the problems given in the form of story questions. Low self-confidence is also an influence on student success because self-confidence itself is self-confidence in doing tasks and choosing good, appropriate and effective solutions. The purpose of this study was to analyze the mathematical representation ability of number material based on self-confidence. The subjects of this study were three class VIII junior high school students who were taken randomly. The data collection techniques in this study were tests, interviews, documentation, questionnaires. The results of this study indicate that: (1) Respondents with a high self-confidence category can solve problems on the sub-indicators of making mathematical equations or models from other representations, making image representations to clarify problems and facilitate solving, making problem situations based on the data or representations provided; (2) Respondents with moderate self-confidence and low self-confidence categories can only solve the problem in the sub-indicator to create a problem situation based on the data or representation provided.
Rendahnya kemampuan representasi matematis siswa berpengaruh terhadap prestasi dalam pembelajaran matematika. Siswa sulit memahami apa yang diketahui dan ditanyakan, juga masih kurang mampu mencari jalan keluar dalam menyelesaikan soal sehingga banyak siswa yang merasa kesulitan dalam menyelesaikan permasalahan yang diberikan dalam bentuk soal cerita. Rendahnya Self-confidence juga menjadi pengaruh terhadap keberhasilan siswa karena self-confidence itu sendiri merupakan kepercayaan diri dalam melakukan tugas dan memilih cara penyelesaian yang baik, tepat dan efektif. Tujuan penelitian ini untuk menganalisis kemampuan representasi matematis pada materi bilangan berdasarkan self-confidence. Subjek penelitian ini adalah tiga orang siswa SMP kelas VIII yang diambil acak. Adapun teknik pengumpulan data dalam penelitian ini adalah tes, wawancara, dokumentasi, angket. Hasil penelitian ini menunjukkan bahwa: (1) Responden dengan kategori self-confidence tinggi dapat menyelesaikan permasalahan pada sub indikator membuat persamaan atau model matematika dari representasi lain, membuat representasi gambar untuk memperjelas masalah dan memfasilitasi penyelesaian, membuat situasi masalah berdasarkan data atau representasi yang diberikan; (2) Responden dengan kategori self-confidence sedang dan self-confidence rendah hanya dapat menyelesaikan permasalahan pada sub indikator membuat situasi masalah berdasarkan data atau representasi yang diberikan.
Spiderwort Control in Hay Fields and Pastures
Authors: Durham Michael , Ferrell Jason , Sellers Brent 
Published: July 2024

This document is about Spiderwort (Tradescantia ohiensis Raf.). This is a native perennial species found throughout the eastern half of the US. It has a large, fleshy stem with long and grass-like leaves. Spiderwort emerges in early spring, then flowers and produces seed through midsummer. This plant is problematic in grazing systems because it is largely avoided by cattle. The large, fleshy stem also makes this plant an issue in hay production. When cut with a grass forage, spiderwort does not dry at the same rate as grass and can cause spoilage when the hay is baled.

Published: July 2024

Speciation of selected heavy metals in Abuja metropolitan soil samples was investigated using a sequential extraction analytical technique. Flame atomic absorption spectrometer was used for instrumental analysis. Metals were bound in six operational phases, in the sequential extraction method. Pb, Mn and Cd speciate more in exchangeable, As and Ni speciate more in bound to carbonate, Cu and Fe speciate more in bound to Fe-Mn oxide, Cr and Zn speciate more in organically bound while Al speciate more in residual in urban soil samples. In sub-urban samples, Pb and Cd speciate more in exchangeable and bound to Fe-Mn oxide, Cu speciate more in exchangeable, Al speciate more in bound to Fe-Mn oxide, Fe and Al speciate more in residual, Ni and As speciate more in bound to carbonate, Zn speciate more in organically bound and Cr speciate more in exchangeable and organically bound. Asokoro Forest (control) has most of the metals as non-residuals except Al and As which speciate more in residual phase. Sequence of ionic mobility in decreasing order for Abuja urban soils is as follows: Zn>Cu>Fe>Al>Mn>>As>Ni>Cr>Cd>Pb and in sub-urban soil samples is: Zn>Cu>Fe>Al>Mn>>Ni>As>Pb>Cd>Cr. From the results, it can be deduced that Zn is the ion with highest speciation. This portends danger to Abuja metropolis due to Zn phytoxicity which hinders photosynthesis in plants, thereby increasing the amount of CO2 giving rise to global warming. This requires that relevant authorities should enforce reduction of the activities that lead to abundance of Zn in Abuja soils.

A pot experiment was carried out in the net house of the Department of Soil, Water and Environment, University of Dhaka. The aim of the study was to assess growth and yield performance of Neem seedlings with the different doses of organic and NPK fertilizers. Trichocompost (TC) was used as organic fertilizer. The treatments used in the experiment were: T1: Control (-OM and -NPK), T2: TC (10 ton/ha), T3: TC 5 ton/ha, T4: NPK 100% RDF, T5: NPK 80% RDF + TC 5 ton/h, T6: NPK 60% RDF + TC 5 ton/h, T7: NPK 40% RDF + TC 5 ton/h, T8: NPK 80% RDF + TC 10 ton/h, T9: NPK 60% RDF + TC 10 ton/h, T10: NPK 40% RDF + TC 10 ton/h. Pots were arranged in a Completely Randomized Design (CRD). Plant height and the number of leaves per plant were recorded at a 15-day interval. The tallest plant (78.87 cm) observed with the application of sole Trichocompost 5 ton/ha. Incremental dose of TC and inorganic fertilizer reduces the height of plant. The maximum no. of leaves ( 51.67) was found with NPK 60% RDF + TC 5 ton/h at the stage of 90 days and the next highest amount of leaves (44.67) with NPK 80% RDF + TC 10 ton/h at 90 days after. The lowest height (12.52 cm) and leaf number/plant (8.33) were recorded in control. Maximum fresh and dry weights (root, bark, and leaf) were 17.19 g/plant and 6.24 g/plant, respectively, found in T8: (NPK 80% RDF + TC 10 ton/h). The best growth performance of seedlings was observed in T8: NPK, 80% RDF, and TC 10 ton/h .The research indicated that there was no significant treatment difference on nutrient uptake by the neem seedlings.

Published: July 2024

IntroductionGejie Zhilao Pill (GJZLP), a traditional Chinese medicine formula is known for its unique therapeutic effects in treating pulmonary tuberculosis. The aim of this study is to further investigate its underlying mechanisms by utilizing network pharmacology and molecular docking techniques.MethodsUsing TCMSP database the components, potential targets of GJZLP were identified. Animal-derived components were supplemented through the TCMID and BATMAN-TCM databases. Tuberculosis-related targets were collected from the TTD, OMIM, and GeneCards databases. The intersection target was imported into the String database to build the PPI network. The Metascape platform was employed to carry out Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Heatmaps were generated through an online platform (https://www.bioinformatics.com.cn). Molecular docking was conducted between the core targets and core compounds to explore their binding strengths and patterns at the molecular level.Results61 active ingredients and 118 therapeutic targets were identified. Quercetin, Luteolin, epigallocatechin gallate, and beta-sitosterol showed relatively high degrees in the network. IL6, TNF, JUN, TP53, IL1B, STAT3, AKT1, RELA, IFNG, and MAPK3 are important core targets. GO and KEGG revealed that the effects of GJZLP on tuberculosis mainly involve reactions to bacterial molecules, lipopolysaccharides, and cytokine stimulation. Key signaling pathways include TNF, IL-17, Toll-like receptor and C-type lectin receptor signaling. Molecular docking analysis demonstrated a robust binding affinity between the core compounds and the core proteins. Stigmasterol exhibited the lowest binding energy with AKT1, indicating the most stable binding interaction.DiscussionThis study has delved into the efficacious components and molecular mechanisms of GJZLP in treating tuberculosis, thereby highlighting its potential as a promising therapeutic candidate for the treatment of tuberculosis.

ObjectiveThe emergence of clinical Klebsiella pneumoniae strains harboring acrAB-tolC genes in the chromosome, along with the presence of two repetitive tandem core structures for blaKPC-2 and blaCTX-M-65 genes on a plasmid, has presented a significant clinical challenge.MethodsIn order to study the detailed genetic features of K. pneumoniae strain SC35, both the bacterial chromosome and plasmids were sequenced using Illumina and nanopore platforms. Furthermore, bioinformatics methods were employed to analyze the mobile genetic elements associated with antibiotic resistance genes.ResultsK. pneumoniae strain SC35 was found to possess a class A beta-lactamase and demonstrated resistance to all tested antibiotics. This resistance was attributed to the presence of efflux pump genes, specifically acrAB-tolC, on the SC35 chromosome. Additionally, the SC35 plasmid p1 carried the two repetitive tandem core structures for blaKPC-2 and blaCTX-M-65, as well as blaTEM-1 with rmtB, which shared overlapping structures with mobile genetic elements as In413, Tn3, and TnAs3. Through plasmid transfer assays, it was determined that the SC35 plasmid p1 could be successfully transferred with an average conjugation frequency of 6.85 × 10-4.ConclusionThe structure of the SC35 plasmid p1 appears to have evolved in correlation with other plasmids such as pKPC2_130119, pDD01754–2, and F4_plasmid pA. The infectious strain SC35 exhibits no susceptibility to tested antibioticst, thus effective measures should be taken to prevent the spread and epidemic of this strain.
