Authors: Reed Phil , Adjei-Mensah Priscilla , Truzoli Roberto
Published: April 2022

Background:

Little is known about university students’ views regarding online teaching, one year after COVID restrictions.

Objective:

The current study examined predictors of satisfaction with online teaching and differences in views and predictors between those exposed or not exposed to COVID.

Methods:

340 university students (144 males; 194 females; 2 nonbinary) completed an online survey. The mean age was 25 years, with 132 undergraduates and 208 postgraduates. Students completed the Online Teaching Satisfaction Questionnaire, Center for Epidemiologic Studies Depression Scale, Becks Anxiety Inventory, the Locus of Control Scale, the General Self-Efficacy Scale, and the Brief-COPE Questionnaire.

Results:

Levels of satisfaction with online teaching were reasonable, with about 60% of students satisfied, but satisfaction was not especially high. Students appreciated the efforts of staff but did not find online materials stimulating. Students exposed to COVID needed more external support to be satisfied with their online experience.

Conclusion:

The results indicate that additional support measures will need to be put into place for COVID-exposed students if current online teaching delivery is to continue. Such information may help further developments in online learning, especially if this form of delivery needs to be extended for any length of time.

This study aims to determine the correlation between nutritional adequacy, Fe content, body fat percentage, and muscle mass percentage with physical fitness in football athletes. Adequacy of nutrients (energy, protein, fat, protein and Fe) was obtained with a 2×24 hour recall. The Fe content value of Fe was measured using the cyanmethemoglobin method and sTfR was measured using the ELWASA method. The percentage of fat and muscle was obtained by using a Bioelectrical Impedance Analysis tool. Physical fitness was measured using the ACSPFT (Asian Committee on Standardization of Physical Fitness Test) test which includes long jumps, pull-ups, sit-ups, sprints or sprints, shuttle run tests, sit and reach and long runs. The bivariate statwastical test used was the Pearson and Rank-Spearman correlation test, while the multivariate test used the Linear Regression test. There was a correlation between carbohydrate adequacy and physical fitness (p = 0.008). Physical fitness related to carbohydrate adequacy was agility and hand muscle strength (shuttle run and pull-up). There was no correlation between adequacy of energy, protein, fat, Fe Content, fat percentage, muscle percentage and physical fitness of athletes. The results of multivariate analysis showed that the most influential on physical fitness was fat adequacy (Rsquwere=14,6%).

The use of the dry reforming of methane (DRM) to convert the two principal greenhouse gases, methane and carbon dioxide, to syngas (a mixture of H2 and CO) has attracted increasing attention in recent years. However, the DRM reaction suffers from the twin disadvantages of carbon deposition and sintering, so a highly efficient and robust catalyst with superior anti-deactivation properties is required. One way to meet this need is to incorporate active metals into crystalline oxides, such as perovskite. In this paper, recent advances in the application of perovskite catalysts in DRM are summarized, with particular attention paid to enhancing interfacial interaction, oxygen vacancies, and surface basicity. The structure-performance relationship is also discussed in depth.

Published: April 2022

Background

Although the benefits of yoga are well established across the world, there are limited studies exploring the long-term interrelation between yoga, meditation, and health. Specifically, there is limited research exploring the differences in health-related quality of life (HRQOL) among regular meditators and nonmeditators.

Objective

This study explored the differences in 7 domains of HRQOL (including quality of life, ability to adopt a healthy lifestyle, ability to relax, frequency of nervousness and stress, coping with day-to-day stress, workplace productivity, and staying healthy during the COVID-19 pandemic) among practitioners of yoga and meditation.

Methods

A cross-sectional, online survey was distributed to all members who participated in a 100-day yoga and meditation program, culminating in the International Day of Yoga event, organized by the Heartfulness Institute in partnership with the Central Council for Research in Yoga and Naturopathy, Ministry of Ayush, SVYASA Yoga University, and Patanjali Yoga Institute, India. The program consisted of daily virtual yoga, meditation, and speaker sessions. The data were analyzed by nonparametric Mann-Whitney U test and Kruskal-Wallis tests for continuous variables and chi-square test for categorical variables.

Results

A total of 3164 participants from 39 countries completed the survey. Mean age was 33.8 (SD 13.6) years. The majority of the participants were female (n=1643, 52%) and students (n=1312, 41.5%). Regular yoga and meditation practice was associated with a positive impact on all 7 domains of HRQOL (Mann-Whitney P<.05 and χ2P<.05). Notably, experienced Heartfulness (≥2 years) meditators reported better outcomes in all the domains of HRQOL as compared to those not currently practicing this form of meditation and participants with ≤1 year of Heartfulness meditation experience (P<.05).

Conclusions

This is one of the first cross-sectional studies to explore HRQOL outcomes among participants of a 100-day virtual yoga and meditation program. Overall, a yoga and meditation practice was found to be an effective tool for promoting HRQOL. Regular yoga and meditation practice was associated with factors promoting health and well-being, with long-term meditation practice associated with increased benefits.

Isoflavones (IF) of plant origin with antioxidant activity can also exhibit antidiabetic effects. The study of the antidiabetic effect of the kudzu root extract (Pueraria lobata) obtained using natural deep solvents and containing the isoflavones puerarin, genistein and daidzein in an amount of 40 mg / g of the extract was carried out. Sixty male Wistar rats were used in the experiment. Type 1 diabetes mellitus was simulated by intraperitoneal administration of alloxan solution at a dose of 170 mg / kg. The IF extract was administered intragastrically to diabetic and healthy animals at doses of 100 mg / kg and 200 mg / kg three times a week (12 injections in total). The administration of IF to diabetic rats was accompanied by the correction of hyperglycemia, an increase in glucose tolerance, the normalization of parameters of the functional state of various organs (AST, ALT, urea, total protein), promoted the restoration of the number of β-cells and the content of insulin in them, stimulation of the proliferative process in the pancreatic islets (the number of Ki67 + cells), and was accompanied by an increase in insulin content in blood plasma. Dose dependence was manifested in a more pronounced effect of the dose of IF 200 mg / kg on the restoration of the number of pancreatic islets, β-cells and proliferating cells in the islets and a more significant increase in the level of insulin in blood plasma compared with the dose of 100 mg / kg. When IF was administered to healthy animals, no deviations from the norm in the glycemic control and cytolysis parameters were detected, no changes were found in the islet apparatus, which indicates the absence of the toxic effect of IFs extracted using natural deep solvents.
OFF-AXIS EXACT RAY TRACING ALGORITHM FOR ZERO COMA POINT DETERMINATION IN CLASSICAL AND NON-CLASSICAL REFLECTIVE TELESCOPES
Authors: Herrera J. , Najera M. R. , Guerrero C. A.
Published: April 2022

In this work we present a general algorithm to calculate the zero coma point for classical and non-classical reflecting telescopes with aspherical surfaces. We programmed a general ray tracing function applicable to conical surfaces with asphericity, displacements, and inclinations that can be modified by the users, according to their specifications. This function is used to evaluate the transverse coma and determine the optimal conjunction of shift and tilt of the secondary mirror that prevents the introduction of axial coma during the collimation process. We present the calculation of the zero coma point for the classical telescopes of the National Astronomical Observatory, San Pedro Mártir, Mexico. Furthermore, we show an example of a wide-field telescope with aspherical surfaces, as will be the case of the TAOS-II telescopes, for which the classical analytical expression cannot be used.
COMPREHENSIVE ANALYSIS OF THE FULL TESS ORBITAL PHASE CURVE OF WASP121b
Authors: Eftekhar M.
Published: April 2022

We present the full phase curve analysis of the ultrahot Jupiter WASP-121b using observations from the Transiting Exoplanet Survey Satellite (TESS). Our comprehensive phase curve model includes primary transit, secondary eclipse, thermal emission, reflection, and ellipsoidal tidal distortion. After removing the instrumental systematic noise, we reliably detect the secondary eclipse with a depth of 489−10+16 parts-per-million (ppm), dominated by thermal emission. Using the TESS bandpass, we measure the dayside 2941−150+61K and nightside 2236−97+38K temperatures of WASP-121b. We find that a hotspot is well aligned with the substellar point, leading to the conclusion that there is an inefficient heat distribution from the dayside to the nightside. Our estimated geometric albedo, Ag = 0.069−0.02+0.06, suggest that WASP-121b has a low geometric albedo.

Published: April 2022

We present a VI CCD photometric study and a membership analysis of the globular cluster M56 (NGC 6779). This produced a CMD decontaminated from field stars, which enabled a better confrontation with theoretical isochrones, zero-age horizontal branches (ZAHB) and post-ZAHB evolutionary tracks. Post He-flash evolutionary models with a He-core mass of 0.5 Mʘ and envelopes of 0.04 - 0.18 Mʘ, cover the complete horizontal branch. Models with total mass ≈ 0.68 Mʘ explain the RR Lyrae, while those with a mass ≈ 0.56 Mʘ and a very subtle envelope, explain the Pop II cepheids with a progenitor in the blue tail of the HB. Based on the Fourier decomposition of the V light curve of a single cluster member RRc star, we determined a metallicity of [Fe/H]ZW = −1.96 ± 0.09. Several independent distance determination approaches lead to a mean distance to M56 of ⟨d⟩ = 9.4 ± 0.4 kpc. Finally, we report 5 new variables: one SX Phe, three EB, and one Rrc.
Digital Watermarking Using Machine Learning

Abstract: Digital watermarking is a technique used for the information of the images that provides security for the confidentiality. The repetitions of the multimedia objects (i.e. audio, video, text, etc.) have been protected by some of the developed digital watermarking techniques. Digital Watermarking is the process of concealing messages in digital contents in order to verify the rightful owner of the copyright protection. In this paper we have proposed a method that would assist its users to embed a watermark to the cover image based on an adaptive approach in a much robust way while maintaining the quality of the cover image. The implementation of this algorithm is based upon cascading the features of DWT and PCA using Bhattacharyya distance and Kurtosis. PCA decompose and compress the watermark, which results in better PSNR and NCC values for the tested images. The proposed algorithm uses Bhattacharyya distance and Kurtosis to detect the scaling and embedding factors making it adaptive to the input image rather than providing constant value. Also, we take one step forward by investigating the construction of feed-forward denoising convolutional neural networks (DnCNNs) to embrace the progress in very deep architecture, learning algorithm, and regularization method into image denoising. Specifically, residual learning and batch normalization are utilized to speed up the training process as well as boost the performance. Keywords: Digital watermarking, DWT-PCA, PSNR, Image denoising, convolutional neural network, DnCNN, residual learning, batch normalization.

Abstract: The construction of national highways nowadays is preferred by using rigid pavements as they are durable, have the high flexural strength, can withstand different heavy axle loads, higher design span and moreover they can sustain adverse environmental conditions more efficiently with better ease. Considering their remarkable qualities, the national highways should be constructed by providing the tied shoulders and dowel bars in the transverse joints because they can better resist the fatigue accumulations on the slab with minimum safe thickness which ultimately leads to reduction in the cost of making the road efficiently. In this chapter, for the two different CBR conditions (CBR-9 & CBR-10) and three concrete mix design grades namely (M40, M45, M50) along with different shoulders and dowel bars conditions, the trial methods were carried on the IRC58 Software for bottom-up cracking fatigue analysis for single and tandem axle for day-time (6 hour) traffic and positive temperature differential and top-down cracking fatigue analysis for single, tandem and tridem axle for day-time (6 hour) traffic and negative temperature differential for evaluating the flexural stresses and cumulative fatigue damage values for the slab having dimensions of (3.5m x 4.5m). For determining the safe design, different trails on the thickness parameter of the slab were being adopted so as to get the cumulative fatigue values of BUC and TDC for single, tandem and tridem axles less than one. The results obtained showed that for which grade and CBR condition, the values of flexural stresses and cumulative fatigue damage determined is maximum. It was concluded that the rigid pavements should be constructed by using higher grades like M45 and M50 as the fatigue stresses and cumulative fatigue damage values due to variable single, tandem and tridem axle load repetitions obtained are less as compared to M40 grade.

Abstract: In Indian economy and employment agriculture contributes a major role. Probably most common problem faced by the Indian farmers is they do not optimize crop based on the necessity of soil, as a result they face serious setback in productivity. This problem can be addressed through precision agriculture. This method takes three parameters into consideration, viz: soil characteristics, soil types and crop yield data collection based on these parameters suggesting the farmer suitable crop to be cultivated. Precision agriculture helps in reduction of non suitable crop which indeed increases productivity, apart from the following advantages like efficacy in input as well as output and better decision making for farming.

Seeds of cumin (Cuminum cyminum L.) are widely used as a spice for their distinctive aroma. C. cyminum have been used in traditional medicine to treat a variety of diseases. Literature presents ample evidence for biomedical activities of cumin which is attributed to its bioactive secondary metabolites - terpenes, phenols, and flavonoids. Besides, health effects of cumin seeds have been experimentally validated through phytochemical analysis depicting the presence of a wide array of bioactive secondary metabolites (BASMs) viz., alkaloid, coumarin, anthraquinone, flavonoid, glycoside, protein, resin, saponin, tannin and steroid. Pharmacological studies indicate that BASMs in seeds of C. cyminum exert antimicrobial, insecticidal, anti-inflammatory, analgesic, antioxidant, anticancer, antidiabetic, anti-platelet-aggregation, hypotensive, bronchodilatory, immunological, contraceptive, anti-amyloidogenic, anti-osteoporotic, aldose reductase, α-glucosidase and tyrosinase inhibitory effects. In the present study phytochemical screening, GCMS, FTIR profile of bioactive natural products from C. cyminum has been envisaged. Phytochemical screening revealed the presence of alkaloids, anthraquinones, carbohydrates, coumarins, flavonoids, glycosides, proteins, quinones, saponins, steroids, tannins and terpenoids. GC-MS analysis revealed the presence of 21 compounds, of which Cuminaldehyde was prominent.  FTIR analysis showed the presence of a strong peak value for 15 compounds and medium peak value for 6 compounds. Many of the compounds in the list could be ADMET bioprospected for biomedical applications as natural drug leads.

Knowledge and Perceptions of Generic Drugs: A Cross Sectional Study
Authors: PANIGRAHY SNEHA , Chaudhari Sunetra
Published: April 2022

Generic medicines are pharmaceutical products usually intended to be interchangeable with the originator brand product, manufactured without a license from the originator manufacturer and marketed after the expiry of patent or other exclusivity rights. The current potential economic benefits associated with their use have been exponentially rising and thus, generic medicines are a significant approach to reduce the massive expenditure on medicines. Governments are thus emphasizing on and promoting the usage of generic medicines. However, negative perceptions of their quality influence use and raise issues of certainty and trust in medications. The objective of this study is to identify consumers in terms of their perceptions towards branded and generic medicines in the country. A cross - sectional study was conducted with consumers of various age demographics and location factors. Using convenience sampling, survey forms were distributed to them via social media platforms. For a period of 30 days, 236 respondents had participated in the survey. Assessments of the results were conducted on qualitative data to develop an insight into the perception of medicines amongst the masses. The survey confirmed that generic drug awareness was considerably high among younger age groups than older respondents. An overwhelming 78% respondent understood that generic medicines are cheaper than branded medicines. Regardless, 34.8% of respondents who were aware of generic drugs did not realize that they were less expensive than brand-name drugs. The survey conducted showed a high support for generic substitution. Furthermore, it indicates that programs should be implemented in order to boost generic drug prescriptions by medical practitioners.

The Chicxulub File: Discovering the K-Pg Mass Extinction
Authors:   University of Houston, Wood Barry
Published: April 2022

In 1979 geologists Luis and Walter Alvarez discovered a layer of iridium-rich rock in the Apennine Mountains dating from 66 to 65 million years BP, the time when dinosaurs went extinct. Their theory that an asteroid strike had caused this massive extinction remained speculative and controversial until the 1991 discovery of a telltale crater from a synchronous asteroid impact. The effects of this impact, centered at Chicxulub on the Yucatan Peninsula, were worldwide. Over the years, impact spherules were found at numerous sites, along with evidence of a massive tsunami throughout the Gulf of Mexico and adjacent coasts. From accumulating evidence, the theory was ratified in 2012, though many details remained unknown. However, a series of dramatic discoveries reported from 2019 to 2022 have led to a chronology of events both during and subsequent to the impact. Evidence for the rapid recovery and development of mammals has been found in the fossil record and, thus, the biological foundations of our own emergence. The final 2019 issue of Science (20 December) named this a “superyear” for studies of the Cretaceous-Paleogene (K-Pg) extinction as the runner-up science “breakthrough of the year.” Through these separate discoveries, a coherent hour-by-hour narrative has emerged, marking the onset of the Cenozoic era and providing a foundation for the emergence of Homo sapiens.
Primeras mediciones de isótopos estables de agua y su comportamiento en fiordos de los Campos de Hielo Patagónico Sur, Chile

Stable isotope measurements of seawater from fjords in the Southern Patagonian Icefields area are presented for the first time. Stable water isotope variability was associated with physiographic and oceanographic factors. Isotope depletion and lower salinity were observed at lower depths, which is consistent with shallow estuarine waters. At greater depths, the characteristics of the modified Subantarctic water mass are inferred, and the glacier proximity and temperature do not show a clear relationship with the isotopic contents. These results could be a robust basis for a possible new proxy associated with changes in water masses, freshwater mixing, and paleoclimatic studies.

Small cities have a unique socio-economic and cultural potential for developing Russian regions, which is manifested in their unique features: com- pactness, historical heritage, the existence of rare industries and the local economy. At the same time, today in Russia the realization of their potential is primarily hindered by the existing system of politi- cal institutions and practices. The purpose of the work is to analyze the economic potential of small cities. The paper explores the potential for the devel- opment of small cities in relation to the Russian context. So, the authors consider the features of small cities and highlight their economic, social and political problems. As illustrated by the successful ones, the potential of small cities in various sectors of the economy (primary, secondary and tertiary) is analyzed. The practical significance of the study lies in the possibility of using the studied experi- ence in developing the potential of small cities in various sectors of the economy in the practice of Russian management. As a result, it is concluded that small cities as such can be economically and socially efficient settlements, that is, they can be a completely competitive urbanized unit. However, the tools for the development of such territories should be focused on supporting the promising areas of development, providing an opportunity for independent and responsible development.
