Absztrakt:

Bevezetés: Az őrszemnyirokcsomó-biopszia (SNB) jelentősége az
előrehaladott – 4 mm-nél vastagabb – melanomák kezelésében eddig vitatott volt a
szakirodalomban. Manapság azonban az adjuváns terápiák alkalmazásának
előfeltétele a regionális nyirokcsomók érintettségének szövettani igazolása.
Ugyanakkor az SNB szükségességének kritériumai Magyarországon sem egységesek,
van, ahol jelenleg a vastag melanomák esetén nem végzik el ezt a beavatkozást.
Célkitűzés: Klinikánkon az elmúlt években konzekvensen
elvégeztük az őrszemnyirokcsomók vizsgálatát 4 mm-nél vastagabb melanomák esetén
is, így érdemesnek tartottuk értékelni, hogy ebben a betegcsoportban milyen
arányban fordul elő a tájéki nyirokcsomók klinikailag nem, szövettanilag viszont
detektálható áttéte. Módszer: A klinikánkon 2007 és 2011 között
melanomával diagnosztizált 1133 beteg közül kiválasztottuk azokat a pácienseket,
akiknek 4 mm-nél vastagabb primer tumoruk volt, és retrospektíven értékeltük a
betegek demográfiai adatait, primer daganatuk klinikai, valamint szövettani
jellegzetességeit az őrszemnyirokcsomó szövettani paramétereinek függvényében.
Eredmények: Az 5 éves időszakban 116 olyan, melanomában
szenvedő beteget diagnosztizáltunk, akinél vastag melanoma került sebészi
kimetszésre. 78 páciensnél történt SNB, mely 50 esetben szövettanilag pozitívnak
bizonyult. A betegek átlagos életkora közel 58 év volt.
Következtetés: Klinikánkon évente tíz olyan, vastag
melanomás beteget kezelünk, akinél az őrszemnyirokcsomó szövettani pozitivitása
alapján igazoltuk a betegség metastaticus stádiumát. Eredményeink és a Nemzeti
Rákregiszter adatai alapján akár 100 körülire becsülhető azoknak a pácienseknek
a száma Magyarországon, akiknél ezzel a patológiai stádiumot meghatározó
módszerrel az adjuváns kezelés szükségessége megállapítható. A betegcsoport
fiatal életkorát figyelembe véve, hatékony target/immunterápia adjuváns
alkalmazásával eredményesebben csökkenthető lehet az elvesztett életévek száma,
mint a belszervi metastaticus stádiumban megkezdett kezelésekkel. Orv Hetil.

Scientific Approach toward Hadith: A Study of Zaglul al-Najjar’s Work
Authors: Lestari Sri H. , Asparina Atropal
Published: September 2020

This paper discusses the concept of science in hadith. In appropriation with the spirit of integration-interconnection, although it is not a very new issue appearing nowadays, the encounters between sciences and scriptural texts always invite such curiousity in hadith studies. One of the popular works dealing with sciences in hadith is “al-I`jāz al-‘Ilmī fī al-Sunnah al-Nabawiyyah,” written by an Egyptian geologist, Zaghlūl al-Najjār. This paper examines the topic using analytical-descriptive to the data gathered. This article focuses on answering the question on who, what, and how sciences dialogues with hadith in this book which must be influenced by his social and intellectual background. It also pervades scientific concepts and natural phenomena which is recorded in hadith. Therefore, this mini-research is written to perceive how the author explains Sunnah which presents along with his knowledge of natural sciences. Besides, this study also deals to uncover the implications of the author’s scientific approach to the status and validity of the hadith used in his work. This study shows that al-Najjār explains a hadith using the thematic method and directly includes the hadith text that is to be explained. He also supported his explanation with the Qur’anic verses. He explains the hadīth using various forms of scientific data using research reference sources from East and West.

Authors: KUBİLAY Şenol , SELÇUK Kadir , SARIAYDIN Dursun
Published: September 2020

In the present study, a set of hydrogels were synthesized using N-isopropylacrylamide with various cross linkers at various dosages via free radical polymerization. Thermal and structural properties of the synthesized hydrogels were characterized via thermogravimetric analyzer (TGA) and Fourier Transformation Infrared Radiation (FTIR) spectroscopy. The effect of crosslinkers such as N,N´-Methylenebisacrylamide, ethylene glycol dimethacrylate (EGDMA) polyethylene glycol dimethacrylate (p(EGDMA), and polyethylene glycol diacrylate (p(EGDA) (Mn:258, Mn:575, Mn:700) were used in p(NIPAM) hydrogel preparation and their effect on swelling behavior was investigated. It was found that the swelling rate was increased as the molecular masses of the cross-linkers used decreased, whereas the hydrogel prepared using p(EGDA)-700 swelled more than the other p(EGDA) crosslinked p(NIPAM) hydrogels.

Published: September 2020

In this research, effects of macronutrient deficiency (N, P, K, Ca, and Mg) on the production, physicochemical characteristics, minerals, phenolic compounds, and antioxidant capacity of fig fruits (Ficus carica L.) were evaluated using the missing element technique in a controlled hydroponic system under greenhouse conditions. N-deficient plants had no fruit production, while fruits with absence of P, K, and Ca were the most affected in terms of size, weight, and physicochemical characteristics. On the other hand, the concentration of minerals was significantly different (p<0.05), finding some interactions of synergism and antagonism between ions. Phenolic compounds increased in fruits with P and Ca deficiency, as well as the antioxidant capacity DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2'azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)) in the fruits of the treatment -Ca. Regarding the FRAP (ferric reducing antioxidant power) test, higher values were found for all treatments without minerals (-P, -K, -Ca, and -Mg) with respect to the control. The results obtained explain the responses of the fig tree subjected to nutritional deficiencies.
Seed germination, micropropagation from adult and juvenile origin explants and address of hyperhydricity of the Cretan endemic herb Calamintha cretica
Authors: VLACHOU Georgia , Maria PAPAFOTIOU Maria , Bertsouklis Konstantinos
Published: September 2020

The optimum range of temperature for germination (96-100%) of Calamintha cretica, an herb with potential pharmaceutical and horticultural uses, was 15 to 20 °C, with 10 and 30 °C cardinal temperatures. Storage up to one year did not affect germination. The effect of zeatin (ZEA), 6-benzyladenine (BA), kinetin, and 6-γ-γ-(dimethylallylamino)-purine added in MS medium at concentrations from 0.0 to 8.0 mg L-1 was tested for shoot proliferation of both adult- and seedling-origin nodal explants at first- and sub-culture. Both explant types responded similarly during in vitro culture. At cytokinin concentrations up to 1 mg L-1 explant response was high (over 85%) but shoot number per explant was low (1.2-2.2). Increasing cytokinin from 2.0 to 8.0 mg L-1 resulted to an analogous decrease of explant response and shoot length, and an increase of shoot number, particularly when ZEA or BA was used (5.0-6.6 shoots per explant, 0.5-1.0 cm long) with simultaneous though increase of hyperhydricity (up to 50%). The addition of 0.1 mg L-1 naphthaleneacetic acid into the 8.0 mg L-1 BA medium almost eliminated hyperhydricity and increased explant response, while the increase of agar concentration from 8.0 to 12.0 g L-1 eliminated hyperhidricity and induced the highest shoot proliferation (93-95% explant response, 11.2-12.3 shoots per explant, 0.8-1.0 cm long). Microshoots and microshoot clusters rooted (88-96%) on half-strength MS medium either hormone free or supplemented with 1 to 4 mg L-1 indole-3-butyric acid. Plantlets survived at 80% to 100% after ex vitro acclimatization in peat: perlite 1:1 (v/v).
Responses of physiological activities and lateral root anatomical structure of Cercis glabra to waterlogging stress
Authors: LUO Jie , YUAN Long-Yi
Published: September 2020

Cercis glabra is a colour-leaf tree with excellent ornamental value, whereas its physiological and morphological responses to waterlogging stress are still unclear. A potted study was conducted to determine the effects of waterlogging stress on antioxidative enzymes (superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT)), lipid peroxidation (in terms of malondialdehyde (MDA) content), relative electric conductivity, and osmotic substance (free proline) of leaves and aerenchyma, lignification, suberization and Casparian strip of lateral roots of C. glabra. The result showed that the SOD, POD, and CAT activity and free proline content of C. glabra were significantly increased by the different degrees of waterlogging stress compared with the non-waterlogged treatment at 8 and 12 days, and the MDA content and relative electric conductivity of C. glabra leaves were significantly increased under the different degrees of waterlogging stress compared to the non-waterlogged treatment at 16 days, and the degrees of change increased among treatments was ranked as total waterlogged > semi-waterlogged > shallow waterlogged. The lateral roots of C. glabra not only formed developed aerenchyma in the cortex but also formed suberization and Casparian strip in the endodermis under semi-waterlogged treatment at 16 days. These results implied that C. glabra had a certain tolerance to waterlogging stress, which was associated with the increasing antioxidant enzyme activity and osmotic adjustment substance content, and with the formation of aerenchyma, suberization and Casparian strip in the lateral root to adapt to the waterlogged environment.

Published: September 2020

Biogradska Gora National Park in Montenegro is part of the Bjelasica Mountain which belongs to the montane region of the Dinaric Alps. Biogradska Gora is one of the largest long-term preserved forests in the Southeast Europe. In this paper there were compared the main structural characteristics of the old-growth mixed forest of spruce (Picea abies L.), fir (Abies alba L.) and beech (Fagus moesiaca (Domin, Maly) Czecz.), from the preserved area of the Biogradska Gora, with similar managed forests from the same mountain. Basic insight into the structural characteristics of forests of spruce, fir and beech was obtained by analyzing tree species composition and two basic structural elements - number of trees and wood volume per unit area. The obtained data provides overview of the structural characteristics of these forests. The results revealed the production potential of the studied mixed forests. The average quantity of standing volume in old-growth forests of Biogradska Gora indicates very valuable and productive forest ecosystems. Presented data shows that forest ecosystems of spruce, fir and beech in the protected area of the National Park Biogradska Gora are characterized by structurally irregular forests with presence of old trees with relevant growing stock and optimal balance of beech and conifer species, while in managed forests on the same mountain, growing stock is very low and with structure which is far from optimal.
Counting fuel properties as input in the wildfire spreading capacities of vegetated surfaces: case of Albania
Authors: HYSA Artan , TEQJA Zydi
Published: September 2020

Extreme weather conditions characterized by increased peak temperatures and stretched draught seasons are expected to boost up wildfire vulnerability in Mediterranean countries such as Albania. Thus, estimations about wildfire spread capacities of the territory are crucial. In this paper we introduce four new parameters into the indexing method for classifying the forested lands by their wildfire spreading capacity (WSCI). Land cover type via Corine Land Cover (CLC), Plant heat zones, Tree cover density (TCD), and Normalized difference vegetation index (NDVI) are integrated along with the previous set of criteria. The analytical steps of the process are performed in QGIS software including the Semi-Automatic Classification Plugin (SCP) which is useful in calculating NDVI values. The diversity among the inventory values of the selected criteria urges for a normalizing procedure within QGIS. Besides, each criterion is foreseen to have a specific impact on the WSCI value, which is weighted via Analytic Hierarchy Process (AHP). The sum of the products of the normalized class and the weighted impact factor of each criterion generates the WSCI value. The validation relies on the comparison between the index values of points being located within the burned areas and the values of the remaining locations. The results have shown that the former set of points have higher WSCI mean value then the latter group of points. Lastly, the parametric vulnerability assessment method presented here enables useful materials in support of wildfire risk reduction within the national priorities of disaster risk management and fire safety agendas in Albania.
Comparative study on in vitro micropropagation response of seven globe artichoke [Cynara cardunculus var. scolymus (L.) Fiori] cultivars: open-pollinated cultivars vs F1 hybrids
Authors: OZSAN Tugce , ONUS Ahmet N.
Published: September 2020

Globe artichoke [Cynara cardunculus var. scolymus (L.) Fiori] growing has gained commercial importance in recent years due to its consumption as food. It has also started to attract attention in pharmaceutics. Due to globe artichoke’s stated importance, growers need large amount of pathogen-free, healthy starting materials for production. Stated material will maximize the yield while minimizing the costs. Hybrid cultivars have uniform in height and maturity and could be harvested concurrently; on the other hand, an open-pollinated cultivar would have useful potential that could be smoothly produced locally at a lower cost. In vitro micropropagation enabling these goals as it serves large scale, fast, reliable and realistic alternative method to classic propagation via offshoots. The aim of the present study was to comparatively evaluate the micropropagation efficiency of two important local open-pollinated (OP) cultivars (‘Bayrampaşa’, ‘Sakız’) and five F1 hybrid cultivars (‘Olympus’, ‘Madrigal’, ‘Sambo’, ‘Green Globe’, ‘Imparator’), on the basis of total subcultures they were subjected to. Various plant growth regulators at various combinations were assessed for in vitro micropropagation and subsequent in vitro rooting. 3/4 basic MS medium supplemented with 0.05 mg  L-1 BA + 0.005 mg L-1 IBA was determined as the best media combination for in vitro micropropagation, while 10.0 mg L-1 IAA + 1.0 g L-1 activated charcoal adding to 1/2 basic MS medium had positive effects on in vitro rooting. According to results, the micropropagation efficiency varied based on cultivar differences and number of subcultures regardless of being OP or F1 hybrid. The present study demonstrated that in vitro propagation of globe artichoke could be a valuable process for assessing mass propagation regardless of using F1 or OP cultivars. Considering the OP cultivars are cheap in terms of price in a comparison to F1 hybrid cultivars, OP cultivars could be also recommended to be used for in vitro mass propagation.
Iconography of domesticated sunflower
Authors: JANICK Jules
Published: September 2020

Sunflower (Helianthus annuus L.) is indigenous to the New World with domesticated types characterized by a single stem with a large seed head. Archeological evidence has indicted that domestication occurred in the Eastern United States. However, images of domesticated sunflower are found in a pre-Hispanic Aztec stone sculpture, various 16th century images from New Spain (present day Mexico), and 16th century European herbals based on imported seed. Iconographic, linguistic, and archaeological evidence confirm that the domesticated types were known by the Aztec previous to the conquest of Cortés in 1522. This evidence suggests either an independent domestication of sunflower in Mexico or a pre-Hispanic migration from North America.

The objective of this study was to estimate genotype by locality, by year, by treatments (G×LxYxT) interaction using AMMI model, to identify maize genotypes with stable number of rows of grains performance in different growing seasons. The trials conducted with seven maize lines/genotypes, four treatments, two years and at the two locations. The results showed that the influence of genotype (G), year (Y), locality (L), and G×L, G×T, G×L×T, G×Y×T, G×Y×L×T interaction on maize number of rows of grains were significant (p<0.01). The genotype share in the total phenotypic variance for the grains number rows of was 53.50%, and the interaction was 21.15%. The results also show that the sums of the squares of the first and second major components (PC1 and PC2) constitute 100% of the sum of the squares of the interaction G×L. The first PC1 axis belongs to all 100%, which points to the significance of the genotype in the total variation and significance of the genotype for overall interaction with other observed sources of variability. The highest stability in terms of expression of the grains number of rows had the genotype L-6, followed by the genotypes L-4, L-5 and L-3. The lowest stability was demonstrated by the genotypes L-2 and L-1, which confirmed that these genotypes are not important for further selection in terms of this trait.

Published: September 2020

We demonstrate antisolvent vapor assisted diffusion as a unique technique for controlled nucleation and better crystallization of methylammonium lead iodide, perovskite absorber film for solar cell applications. Our observations also suggest that due to non-covalent weak interaction
between the perovskite absorber and the high boiling point antisolvent, Ethylacetate (EA), a new microstructured morphology (micro-rods) evolves in the film, which we report for the first time. It is believed that the changed morphology of the mesoporous films for the high boiling point antisolvent,
exhibits better fill factor and results in 32% enhancement of power conversion efficiency than the low boiling point antisolvent, Dichloromethane (DCM), diffused and as-deposited films, thereby suggesting one more parameter to achieve better device performance.
A Brief Study on Quantum Computing
Authors: Chatterjee Preeta , Chakraborty Rishika
Published: September 2020

In the twentieth century, quantum physics is one of the most successful approaches in scientific progress. To theorize the concept of quantum computing Max Planck's idea of the existence of energy in individual units like matter was used. Since then, the idea of manufacturing quantum
computers for everyday use is becoming more plausible with technological advances in quantum theory. A classical computer carries out logical operations using a bit which is either 1 or 0. In contrast to a classical computer, a quantum computer works with a quantum bit or qubit, which is not
limited to two states only. Qubits can exist in a superposition of the two states creating parallelism. Qubit represents the state of atoms, ions, photons or electrons. These qubits which work together with a control device act as a computer memory.Quantum computers have the potential
to become million times more potent than present-day supercomputers due to the presence of these multiple states simultaneously. Concepts and ideas of quantum computing have been demonstrated by different methods like Ion Trap, Quantum Dot methods etc. However, the actual realization of such
a superior system is still in the future. A strategy must be formulated to maintain decoherence and other potential sources of error at a permissible level.Astonishingly, quantum computing took a long time to take off, even though the physicists have known about the world of subatomic
particles. Even so, it took computer scientists another half-century to consider harnessing quantum effects for computation. Also, it was later discovered that quantum computers could solve quantum mechanical many-body problems that are impractical to solve on a classical computer. The foundations
of the subject of quantum computation may have become well-published, but the knowledge is still growing. Hence here is a research paper based on the study of quantum computation.
Autogenous and drying shrinkage of mortars based on Portland and calcium sulfoaluminate cements
Authors: Sirtoli Davide , Wyrzykowski Mateusz , Riva Paolo , Lura Pietro
Published: September 2020

Calcium sulfoaluminate (CSA) cement can be used as an alternative binder in concrete, partially or fully replacing ordinary Portland cement. While CSA cement considerably accelerates the mechanical properties development, the rapid evolution of the microstructure together with the high water demand cause rapid and large volume changes at early ages. As volume changes may lead to early-age cracking, measures to reduce them may be required In this paper, autogenous and drying shrinkage are studied in mortars prepared with Portland cement, CSA cement or a 50/50 blend as binder. Very fast self-desiccation and high autogenous shrinkage of the CSA-based mortar were observed compared to the mortar made with Portland cement. On the other hand, the early-age volume changes can be limited if a blend of the two cements is used. The blended system revealed a bi-modal trend in the evolution of self-desiccation and autogenous shrinkage, in which the initial fast self-desiccation and shrinkage enter the dormant phase after the first couple of days and again start after about 28 days.
Reinforcement of dowel-type timber joints with self-tapping screws
Authors: Elbashir Douaa , Branco Jorge M. , Rodrigues Leonardo G.
Published: September 2020

This paper addresses the assessment of timber-to-timber dowel-type joints in double shear, reinforced with self-tapping screws (STS). This type of joint is known to be less prone to brittle failure as the screws tend to increase the embedding strength while preventing premature splitting. This theory was tested through an experimental campaign carried out for joints of maritime pine (Pinus pinaster Ait.) and Scots pine (P. sylvestris L.). Monotonic and cyclic tests were performed, with and without reinforcement, and the results were analysed. The results highlight the effectiveness of the reinforcement in preventing premature splitting while increasing the capacity of the joints to sustain higher displacements. The contribution of STS was more evident in the fully reversed cyclic tests, where the reinforcement played a crucial role in increasing the ductility and energy dissipation. The use of STS, perpendicular to the dowel, allows the reinforcement of dowelled joints with insufficient end distances.
Investigating the seismic behaviour of high-performance steel plate shear walls
Authors: Ghamari Ali , Johari Naeimi Amir
Published: September 2020

Steel plate shear wall (SPSWs) have good ductility, high strength and stiffness, and considerable energy absorption capability. These advantages have been confirmed in experimental and numerical studies. However, despite these advantages, the need for huge columns surrounding the infill plates is the main limitation of SPSWs. Although the high-performance steel plate shear wall (HPSPSW) has solved this shortcoming, there are still some unknowns about this high-performance system. The HPSPSW system is expected to be more economical than other resisting systems due to ease of fabrication, the elimination of complete joint penetration field welds, the elimination of stress transfer from infill plates to main columns, the higher modification factor and no need for huge main columns. A comparison of analysis results of HPSPSW and SPSW systems revealed that the HPSPSW has desirable stiffness, ductility and energy absorption when its length to height ratio is greater than 1.5. In addition, the HPSPSW system had an ultimate lateral strength only 2–5% lower than that of the SPSW. Modification factors were calculated and average values of 6.67 and 8.64 were obtained for the SPSW and HPSPSW systems, respectively. Therefore, a modification factor of 8.5 is suggested for the HPSPSW.

While Cardiovascular System Diseases constitute a large part in sudden unexpected suspicious deaths, acute aortic dissection (AAD) is the most common pathology in sudden death among aortic diseases. True diagnosis is the best strategy to avoid malpractice. The diagnosis of aortic dissection remains clinically challenging and the outcomes from this disease are often fatal. For this reason, it was aimed to emphasize to 3 cases that were autopsyed by us, applied to health institutions with different symptoms, and the cause of death, bypassing the Acute Aortic Dissection, which died as a result of misdiagnosis and treatment, AAD can be difficult to recognize, diagnosis is therefore sometimes delayed or missed. Physicians who didn’t think that probability in their differential diagnosis will be always accused about malpractice.

Authors: Fodor Szabina , Balázs Balázs
Published: September 2020

This paper presents a study on data retrieved from a gamified team building application, which promotes employees’ joint sport activities. The aim of this work is to identify and evaluate behavior usage patterns, and user engagement indicators based on interaction data gained from the application and to determine key factors affecting engagement levels. In order to determine behavioral patterns, users have been tested for system use, for participation at events and competitions, and for having tendency in social interactions. The study classified three typologies of engaged users: the Achievers who are motivated by the reward of achieving long-term goals, the Socializers who enjoy interacting with others and the Conquerors who like struggling until they eventually achieve victory by defeating others. We were also able to reveal additional influencing factors beyond personal behavior patterns like the corporate culture and the importance of the ‘organizers’.
Does a greater training load increase the risk of injury and illness in ultramarathon runners? : A prospective, descriptive, longitudinal design
Authors: Craddock Nicole Leigh , Burgess Theresa , Buchholtz Kim
Published: September 2020

Background: Ultramarathon running has become extremely popular over the years. Despite the numerous health benefits of running, there are also many negative effects of running, such as increased risk of musculoskeletal injury and illness. Monitoring of an athlete’s training load has become extremely important in terms of injury prevention. Currently, the relationship between training loads and injury and illness incidence is uncertain.

Objectives: To determine if there are any associations between injury and illness incidences and training loads among ultramarathon runners in the 12 week period preceding an ultramarathon event and the four week period after the event.

Methods: This prospective, descriptive, longitudinal study design was conducted in 119 runners who were training for the 2019 Two Oceans ultramarathon event. Data were collected once a week via an online logbook over 16 weeks. Training parameters measured included weekly average running distance, average duration, average frequency and average sessional RPE. Injury data included injury counts, the structure injured, the main anatomical location and the time-loss as a result of injury. Illness data included illness counts, the main illness-related symptoms and the time-loss as a result of illness.

Results: The overall injury incidence was five per 1000 training hours and the overall illness incidence was 16 per 1000 training days. There was a significant relationship between external training load and injury and illness incidence for those who ran less than 30 km per week. There was also a significant relationship between the ACWR (Acute Chronic Workload Ratio) and injury incidence when the ACWR was >1.5 and for illness incidence when the ACWR was <0.5.

Conclusion: The use of both absolute and relative workloads in the monitoring of an athlete’s training load with the aim of minimising injury and illness risk and maximising performance in ultramarathon runners is recommended.

Published: September 2020

Geared by the scant number of studies on EFL teachers’ classroom management in remote secondary schools in Indonesia, this study seeks to investigate teachers’ involvement in classroom management complexities and to what extent they deal with such predicaments. Data were collected through interviews with the teachers within three months and analyzed narratively. The findings suggest that they encountered multi-facet complexities such as (a) lacking learning facilities in terms of electricity supply, (b) students’ demotivation and inability to use English, and (c) teachers' dilemmas in applying the new curriculum. To deal with such quandaries, the teachers made use of (a) a teacher-centered approach, (b) group learning, (c) students’ row seating positions, and (d) non-integrated language skills learning. The implications of this study are discussed at the end of the paper.

Self-efficacy, or confidence in one’s ability to do a task, is a key element that affects students’ motivation and performance. For that reason, the main purpose of this study was to collect specific information about students’ self-efficacy and factors affecting it. This includes comparing the differences between three Moroccan universities representing public and private institutions in terms of students’ self-efficacy. A sample of 365 undergraduate students responded to the questionnaire on self-efficacy for self-regulated learning on a 5-point Likert scale. The findings demonstrate that students' level of self-efficacy is moderate. With regard to the differences between the three universities, a slight difference was found in favor of the private one. Meanwhile, third-year students reported greater self-efficacy than first and second-year students. However, no statistically significant differences were found between male and female students. More importantly, the results reveal that students’ living circumstances during the academic year and their initial motive behind enrolling in university affected their self-efficacy beliefs. Overall, this study provides teachers and practitioners with insights about self-efficacy that could be used to promote students’ success in Moroccan universities.

This study is aimed at developing a home textile product, namely, comforter by using felt. Commercial triple layer comforter products consist of two outer fabric layers with a layer of insulation between them, i.e. middle layer is batting which is usually made of down feathers, polyester or wool. The four common major combinations taken for this study include, CF1C, CF2C, BF1B, BF2B (C – Cotton, B – Bamboo, F1 – 270 gsm Acrylic felt, F2 – 370 gsm Acrylic felt). Each combination has been produced with four stitch variations. There are different types of stitches that can be done in a comforter to secure the felt in the middle layer, it also influences the thermal insulation. Four types of stitch variations have been chosen to compare the influence on thermal insulation property of a comforter. They are vertical, karo step, sewn thru and framed sewn thru. So finally, sixteen combinations have been chosen and analyzed for quality performance tests. The performances are compared and evaluated. The end product has been developed as a comforter with CF2C combination and a sewn through stitch variation which gives better thermal insulation
The reception history of Beowulf
Authors: Bjork Robert E.
Published: September 2020

This paper traces both the scholarly and popular reception of the Old English epic Beowulf from the publication of the first edition of the poem in 1815 to the most recent English novel based on it from 2019. Once the work was first made available to the scholarly community, numerous editions in various languages began to appear, the most recent being in English from 2008; once editions were published, Old English scholars around the world could translate the text into their native languages beginning with Danish in 1820. Translations, in their turn, made the poem available to a general audience, which responded to the poem through an array of media: music, art, poetry, prose fiction, plays, film, television, video games, comic books, and graphic novels. The enduring, widespread appeal of the poem remains great and universal.
He forbead þæt hi ne weopon: A negative element in the þæt-clause introduced by a verb of prohibition
Authors: Ogura Michiko
Published: September 2020

In ICEHL 20 at the University of Edinburgh, I made a report of my research on this theme. The present paper gives additional facts on the construction of a verb of negation followed by a þæt-clause with a negative element. What I try to exemplify is not a historical change from expletive negative to affirmative clause, but the facts that (i) the expletive negative was one of the correlative constructions based on Old English syntax and (ii) the affirmative clause was already found in early Old English together with the negative clause, even though the negative clause was frequent in late Old English to early Middle English and then decreased after late Middle English. The verb with negative import with a negated þæt-clause is, therefore, not an illogical expression but a stylistic device of combining the negation of the governing verb with the content of the governed, negated þæt-clause.
Sobre mulheres subterrâneas e exumação narrativa

Published: September 2020

O presente artigo tem como objetivo propor uma leitura do romance Desesterro (2015), escrito pela autora paulista Sheyla Smanioto, a partir de textos teóricos sobre literatura marginal, identidades marginais e subalternidade. Esta leitura parte da compreensão de que o texto de Smanioto incorpora processos de subjetivação das personagens que não são comumente tratados em textos literários e que vão além da questão da fome, da violência e da miséria em contextos de vulnerabilidade e exclusão social, ainda que passem também por tais questões. Desse modo, a fim de melhor refletir sobre a problemática apresentada, serão mobilizados os trabalhos de Spivak (2010), Dalcastagnè (2012) e Nascimento (2009) para pensar as implicações da subalternidade e identidades marginais, bem como as discussões de bell hooks (2015) e Michel Foucault (2004, 2008) sobre a produção de identidades e os processos de subjetivação e objetificação.

This study aimed to evaluate the effect of using steel plate shear walls (SPSWs) on the earthquake response of reinforced concrete (RC) moment resisting frames. For this, two types of RC frames, namely, ductile and nominally ductile RC frames were used. Each frame structure had five storeys and three-bays. The first storey height was 4 m while the height of the other storeys was 3 m. To upgrade the performance of the existing structures under seismic actions, a special unstiffened SPSW system was incorporated into the middle-bays of each frame. SPSWs consist of an infill steel plate, horizontal and vertical boundary elements such as beams (as HBEs) and columns (as VBEs). The structures were modeled analytically using a finite element method and evaluated by both nonlinear static (pushover) and time history analyses. In the pushover analysis, the first mode load distribution and uniform load distribution were used. In the dynamic time history analysis, a set of ground motion records was employed. As a seismic hazard level, 2% probability of exceedance in 50-year period was taken into consideration. The seismic response of the ductile and nominally ductile RC frames with and without SPSWs was examined comparatively. The results indicated a considerable enhancement in the earthquake performance of both the ductile and the nominally ductile RC frame structures with SPSWs.
Performance Evaluation of Capsule Networks for Classification of Plant Leaf Diseases
Authors: Altan Gökhan
Published: September 2020

Deep Learning (DL) is a high capable machine learning algorithm which composed the advanced image processing as feature learning and supervised learning with detailed models with many hidden layers and neurons. DL demonstrated its efficiency and robustness in many big data problems, computer vision, and more. Whereas it has an increasing popularity day by day, it has still some deficiencies to construe the relationship between learned feature maps and spatial information. Capsule network (CapsNET) is proposed to overcome the shortcoming by excluding the pooling layer from the architecture and transferring spatial information between layers by capsule. In this paper, CapsNET architecture was proposed to evaluate the performance of the model on classification of plant leaf diseases using simple reduced capsules on leaf images. Plant leaf diseases are common and prevalent diseases that disrupt harvesting and yielding for agriculture. CapsNET has capability of detailed analysis for even small stains that may lead seed dressing time and duration. The proposed CapsNET model aimed at assessing the applicability of various feature learning models and enhancing the learning capacity of the DL models for bell pepper plants. The healthy and diseased leaf images were fed into the CapsNET. The proposed CapsNET model reached high classification performance rates of 95.76%, 96.37%, and 97.49% for accuracy, sensitivity, and specificity, respectively.
