The Effect of E-Learning on Students’ Learning at the Varsity Level
Authors: . Suerni
Published: March 2021

The COVID-19 pandemic has spread worldwide, including Indonesia. The Indonesian government recommends all citizens to stay at home and to work and study from home. Therefore, most universities have implemented e-learning in their teaching and learning process. This research focused on the effect of e-learning on students’ interest and learning at the varsity level. Quantitative research methods were used. The data were collected from 176 students from two private universities in Medan, Sumatera Utara. The findings were that e-learning enabled the students to access the global world and distribute learning materials through WhatsApp. Assignments were marked promptly and e-learning helped students to set their own schedule. E-learning motivated the students to do their own work without others’ help, but the students did not agree that e-learning enhanced the quality of the teaching-learning process.

Authors: Bayu Purnama Tri , Sadri Idris
Published: March 2021

This study aimed to determine the English-language public health literacy of public health students. Literacy of public health constitutes proficiency and application of complex skills such as reading, critical and analytical thinking, listening and decisionmaking skills about emerging health situations. We used a quantitative approach with cross-sectional research to investigate the extent of English-language public health literacy among first year public health students. There were 110 participants in this study, all of whom were first year students of the Faculty of Public Health/ Public Health Study Program in North Sumatra Province and more than half were 18 years old with the sex dominated by women. The English-language public health literacy was quite high while students had limitations in understanding the content and main ideas of the articles they read. Students tended to hesitate to disseminate and explain information because they were not confident in their literacy skills. These findings can be used as material for English language curriculum evaluation and competency adjustment of public health students at college level.

Sarcasm Identification of Batak Toba Culture in the Mandok Hata New Year Celebration
Authors: Muharrami Ulya
Published: March 2021

This research investigated the variety of language styles of sarcasm in the Mandok Hata New Year celebration. By analyzing the style of language, the researcher found the true meaning of an utterance in accordance with the intention of the speaker. In this research, the writer conducted the analysis of Mandok Hata in the New Year celebration by analyzing four videos. The use of sarcasm typically lessens and sometimes enhances the negativity inherent in a sarcastic statement. Using a realistic informal format, participants read either a sarcastic or a non-sarcastic aggressive argument between same-gendered interlocutors and rated the pragmatic goals being expressed using a range of measures taken from previous studies. The results of the study showed all five types of sarcasm could be found in the videos: contrast between a positive sentiment and a negative situation (frequency 4); contrast between a negative sentiment and a positive situation (frequency 13); contrasting connotations (frequency 1); verity negation (frequency 1); and temporal facts extraction (frequency 4). The most dominant style of sarcasm was the contrast between a negative sentiment and a positive situation.

Authors:   Associate Professor of the Department of Integration and European Law of the Kutafin Moscow State Law University (MSAL), Slepak Vitaliy Yu.
Published: March 2021

The article deals with basic aspects of application of EU single market rules to arms trade. In particular the author analyses main barriers to free movement of firearms and other types of weapon in inter-EU trade. The author comes to conclusion that the most effective way to cope such obstacles is a harmonization of Member-States legislation on arms trade at EU level. Current EU secondary legislation seeks to eliminate a threats arising from free movement of arms which makes Member States to close national arms markets for foreign goods in order to protect national security. Doing so the EU uses already existing standards of functioning of internal market and at the same time establishes in its secondary legislation legal guaranties providing the same level of security protection in all Member States. Th us importing and exporting Member States are assured that in both states the same EU security standards are observed and as a rule there is no need to apply national norms to protect security and public order.

En el presente trabajo se determinó la actividad de alfa amilasas y el Falling Number (FN) en harinas de diez líneas experimentales de tritíceas cultivadas en el Campo Experimental de la Facultad de Agronomía, Universidad Nacional de La Pampa, Argentina. Se realizó la conversión de FN al Número de Licuefacción (LN) para obtener la linealidad de la relación con las alfas amilasas. Se evaluó el grado de asociación de la actividad de las enzimas alfa amilasas con los valores de FN y LN. Se encontró variabilidad genética en la actividad amilásica entre las líneas estudiadas. Algunos genotipos presentaron alta actividad de las enzimas alfa amilasas haciéndolos atractivos para su utilización en la producción de bioetanol. Se obtuvo una correlación de Pearson altamente significativa (p<0,001) de 0,92 entre FN y la actividad de alfa amilasas para el año 2014 y de 0,71 para el año 2015. La alta correlación encontrada entre los valores de FN, LN y la actividad de alfa amilasas, indica que esta técnica podría utilizarse en reemplazo del FN en aquellas situaciones en que no se disponga del equipo.
First-Generation Students in Distance Education Program: Family Resources and Academic Outcomes
Authors: Brubacher Michael R. , Silinda Fortunate T.
Published: March 2021

Distance education students have less access to classmates as a social resource and may, therefore, rely more on family members for support. However, first-generation students, or students who are the first in their family to attend university, may lack the academic resources that family members can provide. Overall, first-generation students in distance education programs may be at particular risk of lacking the necessary social capital to thrive in university. This study investigated whether two family resource variables—providing guidance about university and expressing supportive attitudes toward university—varied across generation status among distance education students. The study also investigated whether these family resource variables predicted students’ academic adjustment and academic persistence. A sample of 224 undergraduate, distance education students in South Africa completed an online survey. First-generation students (n = 60) reported receiving less university guidance from family members compared to continuing-generation students. In addition, receiving university guidance predicted students’ academic adjustment. The results suggest that university guidance from family members may serve as a protective factor against potential challenges that can impact students’ academic adjustment, a protective factor that first-generation students are less likely to have.

Implications on soil characteristics and biodiversity in vineyard
Authors: Abad Javier , Hermoso de Mendoza Iranzu , Marín Diana , Orcaray Luis , Santesteban Luis Gonzaga
Published: March 2021

This work seeks to synthesise the knowledge on the use of cover crops in vineyards in the last 20 years, emphasising on the one hand, soil characteristics such as nutrition, organic carbon, structure or erosion and, on the other hand, environmental factors such as soil and biodiversity in vineyards, and gas emissions.A systematic review was made using Scopus-index journals for the past 20 years (1999 - 2018). The selection was independently done by two researchers, selecting a total of 272 published papers related to cover crops in the vineyard. Each article was categorised according to its theme and metadata were created, considering all relevant information from an agro-ecological point of view.The use of cover crops has a positive effect on the vineyard by increasing soil organic carbon (SOC), improving water infiltration and aggregate stability, and reducing erosion and greenhouse gases emission to the atmosphere. Furthermore, there is an increase in biodiversity, both in soil and the vineyard. Finally, cover crops do not constitute as a rule a major competition for nutrients to the vines except for nitrogen when grass covers are used. Contrarily, legume cover crops generally increase N in the soil, although its availability for plants is not immediate.This review constitutes an objective tool to help growers when considering the use of cover crops in vineyards that, based in a systematic review, provides relevant information depending on the characteristics of the growing condition of the vineyard.

Cannabis Yield Increased Proportionally With Light Intensity, but Additional Ultraviolet Radiation Did Not Affect Yield or Cannabinoid Content
Authors: Llewellyn David , Golem Scott , Foley Elizabeth , Dinka Steve , Jones Max , Zheng Youbin
Published: March 2021

Cannabis (Cannabis Sativa L.) is now legally produced in many regions worldwide. Cannabis flourishes under high light intensities (LI); making it an expensive commodity to grow in controlled environments, despite its exceptionally high market value. It is commonly believed that cannabis secondary metabolite levels may be enhanced both by increasing LI and by exposing crops to ultraviolet radiation (UV). However, there is sparse scientific evidence to guide cultivators. Therefore, the impact of LI and UV on yield and quality must be elucidated to enable cultivators to optimize their lighting protocols. We explored the effects of LI, ranging from 350 to 1400 μmol m-2 s-1 and supplemental UV spectra on cannabis yield and potency. There were no spectrum effects on inflorescence yield, but harvest index under UVA+UVB was reduced slightly (1.6%) vs. the control. Inflorescence yield increased linearly from 19.4 to 57.4 g/plant and harvest index increased from 0.565 to 0.627, as LI increased from 350 to 1400 μmol m-2 s-1. Although there were no UV spectrum effects on total equivalent Δ9-tetrahydrocannabinol (T-THC) content in leaves, the neutral form, THC, was 30% higher in UVA+UVB vs. control. While there were no LI effects on inflorescence T-THC content, the content of the acid form (THCA) increased by 20% and total terpenes content decreased by 20% as LI increased from 350 to 1400 μmol m-2 s-1. High LI can substantially increase cannabis yield and quality, but we found no commercially-relevant benefits of adding supplemental UV radiation to indoor cannabis production.
Predicting Key Grassland Characteristics from Hyperspectral Data

Published: March 2021

A series of experiments were conducted to measure and quantify the yield, dry matter content, sugars content and nitrates content of grass intended for ensilement. These experiments took place in the East Midlands of Ireland during the Spring, Summer and Autumn of 2019. A bespoke sensor rig was constructed; included in this rig was a hyperspectral radiometer that measured a broad spectrum of reflected natural light from a circular spot approximately 1.2 metres in area. Grass inside a 50cm square quadrat was manually collected from the centre of the circular spot for ground truth estimation of the grass qualities. Up to 25 spots were recorded and sampled each day. The radiometer readings for each spot were automatically recorded onto a laptop that controlled the sensor rig, and ground truth measurements were made either on site or within 24 hours in a wet chemistry laboratory. The collected data was used to build Partial Least Squares Regression (PLSR) predictive models of grass qualities from the hyperspectral dataset and it was found that substantial relationships exist between the spectral reflectance from the grass and yield (r2 = 0.62), dry matter % (r2 = 0.54), sugar content (r2 = 0.54) and nitrates (r2 = 0.50). This shows that hyperspectral reflectance data contains substantial information about key grass qualities and can form part of a broader holistic data driven approach to provide accurate and rapid predictions to farmers, agronomists and agricultural contractors.
Convection Enhanced Delivery in the Setting of High-Grade Gliomas

Published: March 2021

Development of effective treatments for high-grade glioma (HGG) is hampered by 1) the blood-brain barrier (BBB), 2) an infiltrative growth pattern, 3) rapid development of therapeutic resistance, and, in many cases, 4) dose-limiting toxicity due to systemic exposure. Convec-tion-enhanced delivery (CED) has the potential to significantly limit systemic toxicity and in-crease therapeutic index by directly delivering homogenous drug concentrations to the site of disease. In this review, we present clinical experiences and preclinical developments of CED in the setting of high-grade gliomas.
Structure and Composition of Basement and Sedimentary Cover in the Southwestern Part of the Siljan Ring, Central Sweden: New Data from the C-C-1 Drill Core

Published: March 2021

Results of geological and geophysical investigations of the Siljan Ring impact structure (central Sweden) revealed complicated relationships between Paleozoic sedimentary succession and the Precambrian basement. Tectonic and depositional evolution caused complex geology. Studies of a new drill core from the C-C-1 well provide information necessary for the reconstruction of the geological setting in the southwestern part of Siljan Ring. The whole interval of the core section is from 32.60 to 634.90 m with almost no breaks. The sedimentary cover is 373.55 m thick in total. The sedimentary sequences are predominantly composed of wackestones, mudstones, and shales. In the lower part of the sedimentary section, limestone layers intercalate with black shales. In a result of the investigations, it has been suggested that sedimentary layers represent Late Ordovician and Silurian deposits and have disturbed stratigraphic relations. The basement section is composed of Precambrian meta-volcanic and meta-sedimentary rocks. The contact between the basement and the sedimentary cover is tectonic, not normal sedimentary, in origin. Tectonic processes caused intensive rock fracturing. Four generations of fractures were identified with analysis of fracture relations and mineralization sequence. Only two of them occur in sedimentary rocks that probably belong to the latest stages of tectonic activity. Highly fractured basement rocks in some cases contain open vugs developed along the fractures. Rock matrix is tight either in sedimentary and basement rocks and only micro-porosity space is recognized in cataclastic zones. Single evidence of bituminous filling of micro-porosity zone and partly cemented vug is established in limestone from the lower part of the sedimentary section. These findings are particularly valuable for stratigraphy refinement and tectonic setting reconstructions as well as oil and gas reservoir forecasts.

The cyclic regeneration of human endometrium is guaranteed by the proliferative capacity of Endometrial Mesenchymal Stromal Cells (E-MSCs). Due to this, the autologous infusion of E-MSCs has been proposed to support endometrial growth in a wide range of gynecological diseases. We aimed to compare two different endometrial sampling methods, the surgical curettage and the Vacuum Aspiration Biopsy Random Assay, and to validate a novel xeno-free method to culture human E-MSCs. Six E-MSCs cell lines were isolated after a mechanical tissue homogenization and cultured using human platelet lysate. E-MSCs were characterized for the colony formation capacity, proliferative potential and multilineage differentiation. The expression of mesenchymal and stemness markers was tested by FACS analysis and Real-Time PCR, respectively. Chromosomal alterations were evaluated by karyotype analysis, whereas tumorigenic capacity and invasiveness were tested by soft agar assay. Both endometrial sampling techniques allowed to efficiently isolate and expand E-MSCs using a xeno-free method preserving their mesenchymal and stemness phenotype, proliferative potential and multi-lineage differentiation ability during the culture. No chromosomal alterations and invasive/tumorigenic capacity were observed. Herein we report the first evidence of efficient E-MSCs isolation and culture in Good Manufacturing Practice compliance conditions, suggesting Vabra endometrial sampling as alternative to surgical curettage.

Obesity is a problem in the last decades since the development of different technologies forced the submission of a faster pace of life, resulting in nutrition style changes. In turn, domestic pigs are an excellent animal model in recognition of adiposity-related processes, corresponding to the size of individual organs, the distribution of body fat in the organism, and similar metabolism. The present study applied the next-generation sequencing method to identify adipose tissue (AT) transcriptomic signals related to increased fat content by identifying differentially expressed genes (DEGs), included long-non coding RNA molecules. The Freiburg RNA tool was applied to recognise predicting hybridisation energy of RNA-RNA interactions. The results indicated several long non-coding RNAs (lncRNAs) whose expression was significantly positively or negatively associated with fat deposition. lncRNAs play an essential role in regulating gene expression by sponging miRNA, binding transcripts, facilitating translation, or coding other smaller RNA regulatory elements. In the pig fat tissue of obese group, increased expression of lncRNAs corresponding to human MALAT1 was observed that previously recognised in the obesity-related context. Moreover, hybridisation energy analyses pinpointed numerous potential interactions between identified differentially expressed lncRNAs, and obesity-related genes and miRNAs expressed in AT.

On estimation scales ranging from 0.1 nm to 100 nm, the nanoscale is part of the capacitance components of the physical-synthetic and natural environment. Dimensionality, morphology, structure, uniformity, and agglomeration are all used to classify nanoparticles. Its functionality and effect on the environment and species are influenced by its shape and morphology. The priority research is to determine the effects of nanoparticles on any biological entity that is necessary when designing nanotechnology-based biotechnological and biomedical products. Bacteria have a remarkable ability to reduce metal ions, making them one of the most promising candidates for nanoparticle biosynthesis. Nanoparticles have been researched in the biomedical field for antimicrobial, biosensor, diagnostic imaging, and drug delivery applications. These natural technologies appear to be capable of producing stable nanoparticles with well-defined dimensions, morphologies, and compositions by optimizing reaction conditions and selecting the best bacteria. This work includes a list of the most commonly used microorganisms and associated Nanoparticles, as well as a discussion of current biotechnology and biomedical developments.
Mechanics Modeling of Residual Stress Considering Effect of Preheating in Laser Powder Bed Fusion

Published: March 2021

This study aimed at the investigation of the effect of substrate preheating on residual stress in laser powder bed fusion using a physics-based analytical model. In this study, an analytical model is proposed to predict the residual stress through the calculation of preheating affected temperature profile and thermal stress. The effect of preheating is super-positioned with initial temperature in the modeling of temperature profile using a moving heat source approach; the resultant temperature gradient is then employed to predict the thermal stress from a point body load approach. If the thermal stress exceeds the yield strength of the material, then the residual stress under cyclic heating and cooling will be calculated based on the incremental plasticity and kinematic hardening behavior of metal. IN718 is used as a material example to pursue this investigation. To validate the predicted residual stress, experimental measurements are conducted using X-ray diffraction on IN718 samples manufactured via laser powder bed fusion under different process conditions. Results showed that preheating of the substrate could reduce the residual stress in an additively manufactured part due to the reduction in temperature gradient and resultant shrinkage stresses. However, the excessive preheating could have an opposite impact on residual stress accumulation. Moreover, the results confirm that the proposed model is a valuable tool for the prediction of residual stress- eliminating the costly experiments and time-consuming finite element simulations.

Published: March 2021

Poly (Lactic Acid) (PLA) / Ground Tire Rubber (GTR) blends using Dicumyl peroxide (DCP) as a crosslinking agent were prepared as a route to recycle wastes rubber from the automotive industry. The GTR were exposed to grinding and exhibited mechanical damage, traduced at the rubber network scale by chains scission and/or chemical cross-links breakage. Such damage is accompanied by a decrease of 80% of the rubber chains network density of the initial tire buffing but found independent on the type of grinding (cryogenic, dry ambient) or on the GTR size (from <400 µm to <63 µm). Moreover, the finest sieved GTR contain the largest the amount of reinforcing elements (carbon black, clay) that can be advantageously used in PLA/GTR blends. The melt-blending of these finest GTR particles obtained by cryo-grinding at an amount of 15 wt.% and in presence of the crosslinking agent (DCP), resulted in an optimum improvement of the ductility, energy at break and impact strength of the PLA/GTR blends as compared to neat PLA, while maintaining its stiffness. The results were attributed to (i) the good dispersion of the fine GTR particles into the PLA matrix, (ii) the partial re-crosslinking of the GTR particles and co-crosslinking at PLA/GTR interface and (iii) the presence of reinforcing carbon black into the GTR particles and clay particles dispersed into the PLA matrix.

Published: March 2021

The shift to value-based care is changing the practice of medicine. In order to prepare our orthopaedic trainees to survive in a value-based health-care environment, we must expose them to and educate them about value-based programs. This creates both challenges and opportunities for training programs. Academic medical centers (AMCs) will need to carefully consider how to adopt value-based programs and agreements, and assess whether they need alternative facilities, partnerships, or processes in order to be successful. Process improvement principles to adapt physician behavior, the introduction of outcome metrics into the surgical decision-making process, and the development of team-based care can greatly enhance the likelihood of success. AMCs should embrace these challenges to ensure that their residents are well-prepared for the future.

The recent literature shows that COVID-19 has impacted stock markets around the world in many ways. In this paper, we examine the reaction of the Indonesian stock market to COVID-19. We apply the continuous wavelet coherence methodology to daily COVID-19 related deaths and daily conventional and Islamic stock indices inIndonesia. We find that COVID-19 negatively impacts the returns of both indices and enhances their volatility. We find the Islamic stock index to be more volatile as compared to its conventional counterpart during the COVID-19 outbreak.

We examine the impact of competition and portfolio diversification on banking stability for conventional and Islamic banks in Indonesia. We find that the Islamic banking sector is less stable, when compared to the conventional banking sector. Competition in the banking sector reduces stability, while diversification enhances it. We find that competition negatively impacts the Islamic banks, but diversification has no impact on these banks. An interesting finding is that competition and diversification complement each other in enhancing the stability of the Indonesian banking sector. These findings carry an important policy implication for the banking sector of Indonesia.
