There are four components seen from the UTAUT model, namely Performance Improvement Expectations, Business Improvement Expectations, Social Influence, and Supporting Conditions. The population used in the research were teachers at three schools in Jambi, namely SDN 47/IV, SDN 66/IV, and SDIT Al Azhar. The sample in the research involved 130 teachers in the three schools. The research is quantitative research. Research data were obtained through survey methods and questionnaires. The data analysis used in the research is PLS-SEM. The results indicate that the four components of the UTAUT model had a significant influence on the use of Information and Communication Technology (TIK) applied by teachers in the learning process. The most influential component of UTAUT through Information and Communication Technology applied by teachers is the Supporting Conditions. Based on the results of the research, it can be concluded that the unified theory of acceptance and use of technology model has an influence on the use of Information and Communication Technology (TIK) applied by elementary school teachers in the learning process.

Penelitian tersebut merupakan penelitian kuantitatif dengan jenis penelitian korelasional. Sampel dalam penelitian melibatkan 52 orang tua yang memiliki anak usia 5-6 tahun di Lundar, kecamatan Panti, kabupaten Pasaman, provinsi Sumatera Barat. Teknik pengumpulan data yang digunakan adalah melalui angket atau kuesioner untuk orang tua. Analisis penelitian menggunakan uji korelasi product moment Pearson dengan bantuan IMB SPSS ver. 23. Pada penelitian tersebut, variabel kekerasan verbal termasuk dalam kategori tinggi pada kisaran 66%-79%. Sedangkan variabel harga diri pada anak usia 5-6 tahun di Lundar kabupaten Panti provinsi Sumatera Barat termasuk dalam kategori rendah pada kisaran 40%-55%. Berdasarkan hasil perhitungan uji korelasi, nilai product moment Pearson adalah 0,405 dengan probabilitas 0,003. Nilai koefisien korelasi sebesar 0,405 berada pada kisaran 0,40-0,599, artinya terdapat hubungan yang dikategorikan sedang antara kekerasan verbal dengan harga diri ke arah negatif karena nilai r-nya negatif yang artinya semakin tinggi kekerasan verbal maka semakin tinggi nilai r-nya harga diri yang lebih rendah.

This research was an R&D (research and development) research that aimed to develop snakes and ladders game on acid-base topic, determine validity based on expert judgment, determine the practicality of media based on student response questionnaire assessments, and determine the effectiveness of the learning media. The development of the snake and ladder game learning media followed the ADDIE development framework. The validators in this study were content experts, media experts, and education practitioners. The subjects were students in one of the public schools in the Palembang City. Data collection instruments used validation sheets, student response questionnaires, and test questions. The results of the validity test got an average score of 4,07 meaning that it was feasible. The practicality assessment in small-scale trials got 94,86% which was included in the very practical category, the medium-scale trials of 90,75% and also included in the very practical category. The results of test showed an increase in student learning outcomes. It could be proved by the average post-test score of the experimental group students was 85,12 while the average post-test score of the control group was 78,12 and the Sig. (2-tailed) of the t-test (independent sample ttest) had 0,000 < 0,05, which means the snake and ladder game learning media developed is effective to improve student learning outcomes.

The content change makes it is not worth for reuse cooking oil. One of the damages to cooking oil is caused by heating. The quality of useable oil refers to SNI 01-3741-2013. The sample used in this research is waste cooking oil that is used for 5 times of frying. The quality of the oil can be improved using Nano-Montmorillonite adsorbent. Based on the results of PSA and FTIR characterization, it shows that Nano-Montmorillonite has a nano-scale particle size of 15.3 nm with a percentage of 6%, and the rest are particles that have a size >100 nm with a total percentage of 94% with a respective size of 383.9 nm with a percentage of 59% and 6647.1 nm with a percentage of 35% and have functional groups, namely hydroxyl (-OH), Si-O-Si and Al-Al-OH. Testing of waste cooking oil quality includes organoleptics, acid numbers, peroxide numbers and saponification numbers using Nano-Montmorillonite. Based on the results, the more Nano-Montmorillonite adsorbent was added, the lower numbers of acid, peroxide and saponification in waste cooking oil and the quality of flavor and colour are better. Based on this analysis, Nano-Montmorillonite adsorbent can improve the quality of waste cooking oil.

Extensive studies have shown that these phenomena, known as bromine explosion events (BEEs), ozone depletion events (ODEs) and mercury depletion events (MDEs), respectively, are all triggered by gas-phase reactive bromine species that are photochemically activated from bromide via multi-phase reactions under freezing air temperatures. However, major knowledge gaps exist in both fundamental cryo-photochemical processes causing these events and meteorological conditions that may affect their timing and magnitude. Here, we report an outdoor mesocosm-scale study in which we successfully reproduced ODEs at the Sea-ice Environmental Research Facility (SERF) in Winnipeg, Canada. By monitoring ozone concentrations inside large, acrylic tubes over bromide-enriched artificial seawater during entire sea ice freeze-and-melt cycles, we observed midday photochemical ozone loss in winter in the boundary layer air immediately above the sea ice surface in a pattern that is characteristic of BEE-induced ODEs in the Arctic. The importance of UV radiation and the presence of a condensed phase (experimental sea ice or snow) in causing such surface ozone loss was demonstrated by comparing ozone concentrations between UV-transmitting and UV-blocking acrylic tubes under different air temperatures. The ability of reproducing BEE-induced ODEs at a mesocosm scale in a non-polar region provides a new approach to systematically studying the cryo-photochemical and meteorological processes leading to BEEs, ODEs, and MDEs in the Arctic, their role in biogeochemical cycles across the ocean-sea ice-atmosphere interfaces, and their sensitivities to climate change. 1 Introduction Every year during springtime in the Arctic, a series of episodic photochemical events are observed concurrently in the boundary layer air, including bromine explosion events (BEEs), ozone depletion events (ODEs) and mercury depletion events (MDEs) (

The "sensitizing" effect of oxygen can be substituted by SH inhibitors (iodoacetic acid, iodoacetamide and their spinlabelled variants) as well as by some nitroxide free radicals. The "oxygen effect" is blocked by mercaptoethanole or cooling. Compared with the spectrum of native cells a more symmetrical singlet of larger amplitude, approximately g = 2 value, arose in the ESR spectrum of Janus green B treated cells. The "oxygen effect" observed in the presence of Janus green B differs in several ways from the oxygen effect of ionizing radiation and from the "photodynamic" effect.

Many morphological abnormalities such as facet joint hypertrophy, ligamentum flavum hypertrophy, disc herniation combined with osteophytes associated with LSCS were investigated. Degenerative changes in all the elements of the vertebral bone such as lumbar pedicle thickness (LPT) has not evaluated clearly. The aim of this study to investigate whether LPT can be a morphological parameter to predict LSCS using magnetic resonance imaging (MRI). Materials and Methods: 150 patients diagnosed clinical LSCS and 150 control subjects who did not have LCSC-related symptoms referred to radiology unit to undergo lomber MRI enrolled the study. LPT was measured at the most stenotic level of the L5 vertebra using axial T2-weighted images. Results: The mean LPT value was 14.70±1.94 mm in the LSCS group and 14.23±2.00 mm in the control group and was higher in patient group than the controls but did not reach statistical significance (p=0.082). Conclusion: LPT cannot be an effective factor to predict patients with LSCS.
