Authors: Alauddin Muhammad Syafiq , Mohammad Norazlina , Ab. Malik Normaliza
Published: June 2024

This study’s purpose is to evaluate the clinical performance of Class V restorations in non-carious cervical lesions (NCCL’s) using conventional glass ionomer Riva Self Cure (SDI) materials in a teaching institute for one-year follow-up. Participants with Class V restorations were recruited from the e-clinical database and reviewed after one-year. Two independent calibrated examiners were assigned to the clinical assessment with high inter-examiner reliability (? =0.82). Modified Ryge / USPHS criteria was used for direct evaluation of the clinical performance of restorations. The criteria assessed were anatomical form, the presence of secondary caries, retention, marginal adaptation, surface staining, soft tissue health and post-operative sensitivity. Class V restoration restored with glass ionomer showed 80.9% retention rate. Secondary caries, retention, surface staining and soft tissue health showed high scoring of A (clinically excellent restoration) (>90%). The highest acceptable restoration percentage (A- clinically excellent restoration + B-clinically acceptable) was surface staining while the lowest scoring categories was post-operative sensitivity. There was significant difference between gender and post-operative sensitivity (p<0.05). Spearman Correlation test showed that the gender was significantly correlated with post-operative sensitivity (r=0.48) while marginal adaptation was significantly associated with anatomical form (r=0.36) and secondary caries (r=0.39). In summary, after one-year follow, conventional glass ionomers are still clinically acceptable material to restore Class V and come with minimal complications. Clinical Significance: Class V restorations restored with conventional glass ionomer is still relevant as a material of choice to restore NCCL’s despite the advancement of resin based materials.

Authors: Abdelli Houssam Eddine , Kennouche Salim , De Aguiar José Luis Barroso , Jesus Carlos
Published: June 2024

Industrial waste, including glass and plastic, has become widespread in recent years, harming the nature and environment in which we live. Recycling this waste in concrete appears to be one of the best solutions because of its economic and environmental benefits. In this study, the performance of concrete containing plastic waste in the form of fibers and glass waste as a partial replacement for cement was investigated. The effects of both wastes on workability and air content were studied for fresh concrete mixes, as well as their impact on the chloride penetration and carbonation resistance of hardened concrete. The effect of elevated temperature on the compressive strength, weight loss, and ultrasonic pulse velocity of the different mixes was also tested. The results showed that the combination of two wastes in the same mixture contributed to an improvement in the resistance to chloride penetration by 20.5% in the long term. The addition of glass powder to concrete increases the depth of carbonation, whereas the inclusion of plastic fibers reduces the depth of carbonation.
Science in Qumran Aramaic Texts by Ida Fröhlich
Authors: Currie Joe Morgan
Published: June 2024

Science in Qumran Aramaic Texts primarily explores the astronomical, demonological, divinatory, and medical imaginations of the Aramaic texts found at Khirbet Qumran (e.g., 4Q242, 4Q208–209, and 4Q560), in the Hebrew Bible (Daniel 5), and in Ge’ez translations (e.g., the Book of the Watchers and the Astronomical Book of 1 Enoch). If there is a core argument to the volume, it is that these understudied and fragmentary Aramaic texts must be analyzed on their own terms as witnesses to a distinct scientific tradition. They must not be thoughtlessly lumped together with the Hebrew, often sectarian texts also found at Khirbet Qumran: the Aramaic texts represent their own literary tradition. Nor must they be subordinated to Mesopotamian scientific traditions: the Aramaic texts represent a scientific imagination that, although influenced by Mesopotamia, produced its own innovations.

Published: June 2024

Pengenalan berbagai aspek perkembangan salah satunya perkembangan matematika permulaan sangat penting bagi anak usia 5-6 tahun. Pada kenyataannya saat ini  matematika diangap sebagai hal yang sulit untuk dipelajari dan membosaan. Media dalam mengenalkan matematika khususnya bagi anak usia dini saat ini lebih banyak menggunakan lembar kerja dan tidak mengenalkan secara nyata bilangan-bilangan dalam matermatika permulaan. Tujuan dalam penelitian ini adalah pengembangan media “BANK-KU” dalam mengenalkan matematika permulaan bagi anak. Metode yang digunakan dalam penelitian ini yaitu ADDIE (Analysis, Design, Development, Implementation, Evaluation). Berdasarkan hasil penelitian  pada analisis kinerja yaitu kurang tersedia media interaktif dalam pengenalan matematika permulaan. Pada analisis kebutuhan berdasarkan hasil observasi dan wawancara menunjukkan rendahnya minat anak dalam pengenalan matematika permulaan khususnya berhitung. Melalui hasil tersebut maka dibuat desain media “BANK-KU” yaitu pengenalan konsep bilangan, ganjil genap, penjumlahan sederhana sencara nyata. Setelah melakukan perancangan media tersebut di validasi oleh pakar materi dan media. Masukan dari kedua pakar diperbaiki dan selanjutnya pelaksanaan implementasi, dalam implementasi pada 11 anak terlihat dapat menggunakan media dalam pengenalan bilangan satuan, puluhan, ratusan sampai dengan ratusan, pengenalan ganjil genap, pengenalan penjumlahan sederhana. Terdapat beberapa kendala dalam implementasi yaitu buku panduan yang memerlukan pengembangan dan ratio jumlah anak dalam penggunaan media BANK-KU

Published: June 2024

This study aims to determine the effect of Colocasia esculenta L on the growth and motility of zebrafish (Danio rerio) larvae after induction of rotenone as a stunting model. The Zebrafish have divided 3 groups i.e Normal (embryonic medium without rotenone induction), Negative Control (embryonic medium with rotenone induction), and Treatment Groups (embryonic medium with rotenone induction and Colocasia esculenta extracts, dose 30-60-90 ppm). The stunting model is designed by induction of 12.5 ppb rotenone to Zebrafish larvae. The growth of the larvae was observed by using a microscope to measure the body and head length. Evaluation of motility was carried out by recording the movement of the fish for 1 minute, and the pace was analyzed by using Video Tracker. The evaluations were observed at 3, 6, 9 dpf (day post-fertilization). Colocasia Esculenta Extract (CEE) groups have higher body lengths compared to the Negative Control Group. The lengths were 125.4 µm for CEE30, 119.4 µm for CEE60, and 121.4 µm CEE90 while the length for the Negative Control Group was 118.3 µm at 9 dpf. However, there were no different values for the ratio of head length to body length of all groups. The ratio was 1:6 at 3 dpf, and 1:4 at 6 and 9 dpf. Moreover, the motility was higher in CEE groups compared to the Negative Control at 3, 6, 9 dpf. The body length and motility of Zebrafish larvae higher compare to the Negative Control Group showing the potential of Colocasia esculenta extract on growth and enhancement of motoric activity.

The majority of Indonesian people consume rice as a staple food. According to data from the Central Statistics Agency (2022), rice production in West Sumatra reached 1,482,996.01 tons in 2019 and continued to decline until 2021, total rice production in West Sumatra was only 1,317,209.38 tons. This is inversely proportional to the population of West Sumatra which increases every year, so efforts need to be made to increase rice production. One of them is the biopriming technique to increase seed vigor. Priming is hydration carried out slowly which aims to ensure that the seed's water potential reaches balance and activates metabolism in the seed before the seed germinates. One of them is biopriming, which is a seed priming technique using biological agents in the form of beneficial microorganisms. Several factors influence the success of the priming technique, one of which is the soaking time. The right soaking time provides a deeper opportunity to absorb water to stimulate the seeds to germinate. This research aims to determine the effect of soaking time on biopriming of the local West Sumatran rice variety "Anak Daro" using Bacillus subtilis and Trichoderma harzianum on the germination of the Anak Daro rice variety. Completely Randomized Design (CRD) factorial pattern with 2 factors with 3 replications. Factor A is a biopriming agent, namely A1 (no microbes), A2 (Bacillus subtilis), and A3 (Trichoderma harzianum). Factor B is the length of soaking, namely B1 (24 hours), B2 (48 hours), and B3 (72 hours). The results showed that Bacillus subtilis and Trichoderma harzianum had a significant effect on maximum growth potential and germination, while soaking time had a significant effect on maximum growth potential and vigor index.
