Published: September 2022

IntroductionThe home lockdown due to the appearance of SARS-CoV-2 in Spanish society led to changes in certain habits in children and adolescents. These habits were related to the practice of physical activity and the implications of higher rates of sedentary activities. This lockdown lasted from March to June 2020. The aim of this study was to determine the implication that lockdown in Spain due to the SARS-CoV-2 virus outbreak had on balance in 11–12 year-old schoolchildren.Materials and methodsIn total, 50 Spanish children aged 11–12 years (M = 11.40, SD = 0.50) participated, 33 (66%) boys and 17 (34%) girls. The Movement Assessment Battery for Children 2 (Movement ABC-2) and an ad hoc questionnaire for sociodemographic data and other relevant information were used for the three data collections.ResultsThere are significant differences (p &lt; 0.05) in the results for balance variables measured by static balance tests on supports in the total sample, in boys and girls. There are also significant differences in the total sample as well as in the boys in the heel-toe backward walking test. In addition, there are significant differences in mean, scalar and percentile dimension scores for balance between before and after lockdown in both boys and girls. No significant differences were found in the total sample or by gender in measurements related to the zigzag jumping test with dominant as well as non-dominant leg in girls (p = 0.317).ConclusionAs a consequence of SARS-CoV-2 confinement, there was a worsening of balance values in children aged 11–12 years.

BackgroundDental caries is a multifactorial disease that affects many people. Even though microorganisms play a crucial role in causing dental caries, diagnosis is routinely macroscopic. In order to improve early detection especially in HIV patients who are disproportionately affected, there is need to reconcile the macroscopic and microscopic characteristics of dental caries. Therefore, the aim of this study was to characterize the oral microbiota profile along the decayed, missing, filled teeth (DMFT) index using amplicon sequencing data.MethodsAmplicon sequencing of the V6-V8 region of the 16S rRNA gene was done on DNA recovered from whole unstimulated saliva of 59 HIV positive and 29 HIV negative individuals. The microbial structure, composition and co-occurrence networks were characterized using QIIME-2, Phyloseq, Microbiome-1.9.2 and Metacoder in R.ResultsWe characterized the oral microbiota into 2,093 operational taxonomic units (OTUs), 21 phyla and 239 genera from 2.6 million high quality sequence reads. While oral microbiota did not cluster participants into distinct groups that track with the DMFT index, we observed the following: (a) The proportion of accessory microbiota was highest in the high DMFT category while the core size (∼50% of richness) remained relatively stable across all categories. (b) The abundance of core genera such as Stomatobaculum, Peptostreptococcus and Campylobacter was high at onset of dental caries, (c) A general difference in oral microbial biomass. (d) The onset of dental caries (low DMFT) was associated with significantly lower oral microbial entropy.ConclusionsAlthough oral microbial shifts along the DMFT index were not distinct, we demonstrated the potential utility of microbiota dynamics to characterize oral disease. Therefore, we propose a microbial framework using the DMFT index to better understand dental caries among HIV positive people in resource limited settings.

BackgroundThe contribution of intraoperative parathyroid hormone monitoring to minimally invasive parathyroidectomy remains controversial. We aimed to evaluate whether intraoperative parathyroid hormone monitoring monitoring could contribute to minimally invasive parathyroidectomy in these patients.MethodsThe data of the patients whose preoperative ultrasonography and technetium-99 m sestamibi scintigraphy imagings were positive and concordant for one gland and who underwent minimally invasive parathyroidectomy between 2003 and 2018 in our clinic, were evaluated retrospectively. Blood samples were collected at pre-excisional period, and at post-excisional 10 and 20 min; the intaoperative parathyroid hormone was measured, and the surgery was terminated without waiting for the result. Patients were divided into 2 groups according to the postoperative results, as those with normocalcemia (Group 1) and those with persistence (Group 2).ResultsThere were 195 patients in Group 1 and 14 patients in Group 2. The cure rate at the first surgery was 93.3%. Cure was achieved after the second operation in all patients in Group 2. Recurrent disease developed in 1 patient in group 1 and the overall cure rate was 99.5%. If intraoperative parathyroid hormone had been evaluated, cure could have been achieved at the first surgery with additional exploration, in 10 (71.4%) of 14 patients according to the insufficient decrease in parathyroid hormone value at the 10 min in Group 2, and in 9 (64.3%) of 14 patients according to the parathyroid hormone value at 20 min. However, due to insufficient decrease (false negative) in the parathyroid hormone value at the 10 and 20 min the rate of false negatives and unnecessary exploration would be 9.5% and 2.5%, respectively. With additional exploration, the cure rate in the first surgery could be increased by 4.3%–97.6% according to the 20 min intraoperative parathyroid hormone value.ConclusionThe cure rate in minimally invasive parathyroidectomy can be increased by minimizing unnecessary conversion to bilateral neck exploration, by evaluating intraoperative parathyroid hormone at 10 min in patients with positive and concordant scans, and intraoperative parathyroid hormone at 20 min in patients with inadequate decrease at 10 min intraoperative parathyroid hormone.
Controlling the Oxygen Defects Concentration in a Pure BiFeO3 Bulk Ceramic

Published: September 2022

BiFeO3 is a multiferroic material with a perovskite structure that has a lot of potential for use in sensors and transducers. However, obtaining pure single-phase BiFeO3 ceramic with a low electrical conductivity via solid-state reactions remains a problem that limits its application. In this work, the suppression of secondary phases in BiFeO3 was studied by varying the compositional parameters and the sintering temperature. The addition of 1% Bi2O3 to the stoichiometric precursor mixture prevented the formation of secondary phases observed when sintering stoichiometric precursors. The pure phase ceramic had a p-type conductivity and a three-decade lower electrical conductivity as measured by impedance spectroscopy. Annealing of optimally synthesized material at different partial pressures of oxygen in an oxygen–nitrogen gas atmosphere showed that the reason for this type of conductivity lies in the high concentration of defects associated with oxygen. By annealing in various mixtures of nitrogen and oxygen, it is possible to control the concentration of these defects and hence the conductivity, which can go down another two decades. At a pO2 ≤10%, the conductivity is determined by intrinsic charge carriers in the material itself.

Purpose: Several studies have shown that platelet size is a reliable indicator of platelet activity and, therefore, a valuable biomarker for cardiovascular events. Many inflammatory and prothrombotic disorders have been linked to it. As a biomarker for inflammation and neoplastic disease, This study aims to examine existing research on changes to mean platelet volume (MPV).
Materials and methods: The present study portrays MPV comparison among the female players who participated in three games viz Yoga, Volleyball, and Rugby conducted at the university level throughout India with age groups ranging from 17 to 25 years in the sample. The sample size is 45, with 15 players chosen from each game Yoga, Volleyball, and Rugby.
Results: The results mean, standard deviation (SD), standard error of the mean (SEM), and lowest and maximum scores were used to examine the data. SPSS software was used to do the One-Way Analysis of variance. It was observed that there is a significant difference in the MPV of players from three distinct sports. Furthermore, there exists a one-to-one correspondence between the MPV between the players participating in individual games. The present results displayed the values of MPV among players from different games are independent of one another and unaffected by one another.
Conclusion: The study's findings indicate a significant difference in the MPV of players from three distinct sports. However, when MPV of Volleyball and rugby players were compared, it was discovered that they were connected. In conclusion, MPV among players from different games are independent of one another and unaffected by one another. Variability in MPV was also observed across all sample sizes in the study.

Nonrelevant quantum levels limited laser dynamic in narrow-period terahertz quantum cascade lasers
Authors: Wang Li , Lin Tsung-Tse , Wang Ke , Hirayama Hideki 
Published: September 2022

Abstract
The fundamental challenges faced by terahertz quantum cascade lasers are the operations below room temperature, and the recent improved operating temperatures are actually based on the narrow-period designs (2-well resonant-phonon scheme). In this study, we address the critical effect of nonrelevant high-confined quantum levels on the laser threshold current in such designs, i.e. at high temperatures, the resonant-tunneling channels passing through neighboring periods via those levels can dominantly increase the laser threshold current. As a result, the laser dynamics significantly shrink to zero even at 270 K. The channels cannot be easily eliminated as they are derived from the specific configuration of a two-quantum-well periodic structure, in which the width of the period is narrow, and the nonrelevant levels from the lower-well are confined down in energy. It is reasonable to suppress the current flowing across those levels by narrowing the lower-well further, but an appropriate balance of its thickness is essential.

Published: September 2022

Abstract
Understanding the role of the edge during the growth of hexagonal boron nitride (hBN) by chemical vapor deposition (CVD) is essential for its controllable synthesis and applications. We demonstrated two kinds of hydrogen-induced edge evolution of single-crystal hBN domains over time on liquid Cu via CVD. The morphology and edge evolution of the hBN domains in growth were well explained by the kinetic Wulff construction theory. This work provides a detailed understanding of the role of the edge during the growth progress of hBN, which will be helpful for the production of wafer-scale single-crystalline hBN.

Pendidikan merupakan kunci dan tolak ukur kemajuan suatu bangsa. Semakin maju tingkat pendidikan suatu bangsa, semakin maju pula tingkat kesejahteraannya. Sebaliknya negara yang tingkat pendidikannya rendah dan terbelakang maka dapat dipastikan tingkat pendapatan dan kesejahteraannya tidak terpenuhi, bahkan cendrung miskin. Pendidikan sebagaimana diamanatkan oleh undang-undang Republik Indonesia nomor 20 tahun 2003, pasal 3 menjelaskan bahwa pendidikan nasional berfungsi mengembangkan kemampuan dan membentuk watak serta peradaban bangsa yang bermartabat dalam rangka mencerdaskan kehidupan bangsa bertujuan untuk berkembangnya potensi peserta didik agar menjadi manusia yang beriman dan bertaqwa kepada Tuhan Yang Maha Esa, berakhlak mulia, sehat, cakap, kreatif, serta bertangguang jawab.
Untuk mencapai hal tersebut tidaklah mudah tetapi membutuhksn waktu, pemikiran, kreasi dan inovasi yang terus berkembang oleh para pelaku pendidikan terlebih seiring dengan kemajuan ilmu pengetahuan dan teknologi yang memberi pengaruh besar terhadap dunia pendidikan, terutama para pendidik disekolah dalam prosess belajar mengajar dituntut untuk selalu mampu menyesuaikan diri dengan perkembangan teknologi bagi tercapainya tujuan pendidikan dan salah satu diantarannya dalam pemilihan dan penggunaan metode dan media serta menciptkan suasana belajar yang menyenangka,n dan mampu memotivasi belajar siswa, yang pada gilirannya terbangun interaksi yang positif antara guru dan peserta didik. Apabila hal tersebut dapat di wujudkan maka tujuan pendidikan sebagaimana diamanatkan undang undang akan dapat tercapai sesuai yang diharapkan.

Published: September 2022

Sejarah pendidikian Islam di Indonesia sudah berjalan demikian panjang yang bahkan pendidikan Islam sudah ada sebelum Indonesia merdeka, perjuangan panjang untuk meneruskan syiar keislaman tidak pernah putus sampai dengan saat ini, hal ini dapat dibuktikan dengan berkembangnya pondok pesantren wabil khusus menjamurnya pondok tahfiz Al-Qur’an.
Pondok tahfidz memiliki peminat yang tidak sedikit karena tumbuhnya kesadaran masyarakat akan pentingnya mempelajari dan menghafal Al-Qur’an agar tidak terjerumus kepada pergaulan langsung dengan masyarakat yang kurang mengindahkan agama maupun dengan pengaruh teknologi yang semakin merajai dunia yang dapat menjadi candu bagi anak dalam pemanfaatannya.
Keberadaan pondok tahfidz Al-Qur’an sangat penting sebagai langkah untuk membumikan Al-Qur’an serta memperkokoh nilai-nilai keberagamaan yang mampu mengantarkan generasi muda Indonesia berakhlak mulia, berbudi pekerti yang luhur dan toleran terhadap perbedaan baik menyangkut sikap, peradaban, suku, ras dan lain sebagainya. Untuk mencapai itu semua diperlukan langkah atau strategi yang dapat meningkatkan motivasi dan gairan belajar dan menghapal Al-Qur’an.
