Published: May 2021

Abstract. Flooding is of particular concern in low-lying coastal zones that are prone to flooding impacts from multiple drivers: oceanographic (storm surge and wave), fluvial (excessive river discharge), and/or pluvial (surface runoff). In this study, we analyse for the first time the compound flooding potential along the contiguous United States (CONUS) coastline from all flooding drivers, using observations and reanalysis datasets. We assess the overall dependence from observations by using Kendall’s rank correlation coefficient (τ) and tail (extremal) dependence (χ). Geographically, we find highest dependence between different drivers at locations in the Gulf of Mexico, southeast, and southwest coasts. Regarding different driver combinations, the highest dependence exists between surge-waves, followed by surge-precipitation, surge-discharge, waves-precipitation, and waves-discharge. We also perform a seasonal dependence analysis (tropical vs extra-tropical season), where we find higher dependence between drivers during the tropical season along the Gulf and parts of the East coast and stronger dependence during the extra-tropical season on the West coast. Finally, we compare the dependence structure of different combinations of flooding drivers using observations and reanalysis data and use the Kullback–Leibler (KL) Divergence to assess significance in the differences of the tail dependence structure. We find, for example, that models underestimate the tail dependence between surge-discharge on the East and West coasts and overestimate tail dependence between surge-precipitation on the East coast, while they underestimate it on the West coast. The comprehensive analysis presented here provides new insights on where compound flooding potential is relatively higher, which variable combinations are most likely to lead to compounding effects, during which time of the year (tropical versus extra-tropical season) compound flooding is more likely to occur, and how well reanalysis data captures the dependence structure between the different flooding drivers.
Urban surface water flood modelling – a comprehensive review of current models and future challenges
Authors: Guo Kaihua , Guan Mingfu , Yu Dapeng
Published: May 2021

Abstract. Urbanisation is an irreversible trend as a result of
social and economic development. Urban areas, with high concentration of
population, key infrastructure, and businesses, are extremely vulnerable to
flooding and may suffer severe socio-economic losses due to climate change.
Urban flood modelling tools are in demand to predict surface water
inundation caused by intense rainfall and to manage associated flood risks
in urban areas. These tools have been rapidly developing in recent decades.
In this study, we present a comprehensive review of the advanced urban flood models and emerging approaches for predicting urban surface water flooding driven by intense rainfall. The study explores the advantages and
limitations of existing model types, highlights the most recent advances, and identifies major challenges. Issues of model complexities, scale effects, and computational efficiency are also analysed. The results will inform scientists, engineers, and decision-makers of the latest developments and guide the model selection based on desired objectives.

Published: May 2021

Abstract. Controls on landsliding have long been studied, but the potential for landslide-induced dam and lake formation has received less attention. Here, we model possible landslides and the formation of landslide dams and lakes in the Austrian Alps. We combine a slope criterion with a probabilistic approach to determine landslide release areas and volumes. We then simulate the progression and deposition of the landslides with a fluid dynamic model. We characterize the resulting landslide deposits with commonly used metrics, investigate their relation to glacial land-forming and tectonic units, and discuss the roles of the drainage system and valley shape.
We discover that modeled landslide dams and lakes cover a wide volume range. In line with real-world inventories, we further found that lake volume increases linearly with landslide volume in the case of efficient damming – when an exceptionally large lake is dammed by a relatively small landslide deposit. The distribution and size of potential landslide dams and lakes depends strongly on local topographic relief. For a given landslide volume, lake size depends on drainage area and valley geometry. The largest lakes form in glacial troughs, while the most efficient damming occurs where landslides block a gorge downstream of a wide valley, a situation preferentially encountered at the transition between two different tectonic units. Our results also contain inefficient damming events, a damming type that exhibits different scaling of landslide and lake metrics than efficient damming and is hardly reported in inventories. We assume that such events also occur in the real world and emphasize that their documentation is needed to better understand the effects of landsliding on the drainage system.

Published: May 2021

Las plantas vasculares que no forman semillas son conocidas con el nombre vulgar de helechos, presentando unas 120 especies en la península ibérica, más abundantes en ambientes forestales húmedos y saxícolas. En entornos urbanos y semiurbanos no suelen ser muy numerosos, un hecho que parece estar unido a la escasa presencia de sus esporas en la atmósfera de estas zonas, en comparación con otras partículas biológicas como las esporas fúngicas o los granos de polen. El objetivo de este trabajo es proporcionar una clave de determinación de los tipos de esporas de licófitos y helechos más comunes en los entornos urbanos o sus proximidades, discriminando para ello 12 géneros. Se pretende así facilitar su identificación en muestras aerobiológicas y permitir, con ello, un mayor conocimiento de estos tipos esporales y sus dinámicas atmosféricas urbanas.
Treadmill Running Improves Spatial Learning Memory Through Inactivation of Nuclear Factor Kappa B/Mitogen-Activated Protein Kinase Signaling Pathway in Amyloid-β-Induced Alzheimer Disease Rats

Published: May 2021

Purpose: Exercise is known to reduce proinflammatory cytokines production and apoptosis. We investigated the effect of treadmill running on spatial learning memory in terms of activation of nuclear factor kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathway in Alzheimer disease (AD) rats. We also evaluated the effect of treadmill running on proinflammatory cytokine production and apoptosis.Methods: Using the stereotaxic frame, amyloid-β (Aβ) was injected into the lateral ventricle of the brain. The rats belong to treadmill running groups were forced to run on a motorized treadmill for 30 minutes per a day during 4 weeks, starting 3 days after Aβ injection. Morris water maze task was done for the determination of spatial learning memory. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay, immunohistochemistry for cleaved caspase-3, and western blot for NF-κB, inhibitory protein of NF-κB (IκB), MAPK signaling pathway, tumor necrosis factor (TNF)-α, interleukin (IL)-1β were done.Results: Induction of AD increased proinflammatory cytokine secretion by activating the NF-κB/MAPK signaling pathway. These changes induced apoptosis in the hippocampus and reduced spatial learning memory. In contrast, treadmill running inactivated the NF-κB/MAPK signaling pathway and suppressed proinflammatory cytokine production. These changes inhibited apoptosis and improved spatial learning memory.Conclusions: Current results showed that treadmill running promoted spatial learning memory through suppressing proinflammatory cytokine production and apoptosis via inactivation of NF-κB/MAPK signaling pathway. Treadmill exercise can be considered an effective intervention for symptom relieve of AD.

Published: May 2021

Underactive bladder and impaired bladder compliance are irreversible problems associated with bladder fibrosis. Remodeling of the extracellular matrix is regarded as an important mechanism associated with bladder fibrosis. However, various risk factors and conditions contribute to the functional impairment of the bladder associated with fibrosis, and there is limited knowledge about bladder fibrosis-associated problems in the field of neurourology. Further studies are thus necessary to elucidate the underlying mechanism of bladder fibrosis and to identify effective treatment.

Published: May 2021

La relación entre minería metalífera y acumulación por desposesión es tan antigua como el capitalismo. Sin embargo, las dinámicas expropiatorias intrínsecas a esta actividad no siempre han sido las mismas, variando en función de sus distintos contextos histórico-geográficos.A la luz de esta premisa, este trabajo pone el foco en La Mejicana y Bajo La Alumbrera, las dos minas más importantes que operaron en Argentina a comienzos del siglo XX y el siglo XXI, respectivamente. Sobre la base de las categorías de análisis propuestas por la literatura académica, este artículo efectúa un estudio comparativo de los mecanismos de acumulación por desposesión puestos en juego por el capital en cada caso para identificarsus simi-litudes y diferencias. Los resultados muestran claramente los nexos que unen la acumulación primitiva del pasado con las formas de despojo actuales, pese a sus contrastes en materia ambiental y laboral.

В настоящее время наблюдается значительный рост интереса к цифровым технологиям со стороны бизнеса. Многие компании, в основном малого и среднего бизнеса, переносят интервью и переговоры в системы аудио- и видеоконференцсвязи, руководители крупных компаний также заявляют о необходимости трансформации функции HR в онлайн-формат путем внедрения новых технологий. СМИ публикуют все больше информации о широких возможностях инструментов для реализации данных технологий и невероятных результатах их внедрения. Так, с 2021 года ряд ведущих банков России планирует внедрить в свою деятельность программы, которые будут считывать эмоции клиентов во время телефонного разговора и при посещении им офиса кредитной организации. Однако исследования показывают, что пользователи нередко оказываются разочарованными полученными результатами в связи с ощутимой потерей легкости восприятия мультимодальности информационных потоков. Наличие указанных противоречий требует исследования и разработки новых подходов к проведению онлайн-интервьюирования. Рассмотренный в статье принципиально новый метод эмоционального прогнозирования позволит предсказать успех результата собеседования, определяемого интерактивно задаваемыми пользователем параметрами, что в конечном итоге должно привести к полному снятию проблемы трансформации функции HR в онлайн-формат.

Authors: Зенкина Елена Вячеславовна
Published: May 2021

В рамках данной статьи рассмотрены принципы кредитования, особые признаки эмиссии рыночных долговых обязательств и преимущества их выпуска. При этом отмечается, что эффективным методом привлечения инвестиций для развития бизнеса является выпуск облигационных займов. В начале XXI столетия в мире наблюдается тенденция роста значимости рынка долговых финансовых инструментов в финансировании деятельности компании и сейчас в развитых странах облигационная масса корпораций составляет порядка 15-65% общих объемов эмиссий корпоративных ценных бумаг. В целом, в рамках традиционной модели развития мировой экономики и общепринятой теоретической модели международного движения капитала предполагается активная работа на финансовых рынках. Сегодня в свете поиска мер поддержки малого и среднего бизнеса, а также мер стимулирования инноваций в экономике страны, на рынок корпоративных облигаций в России возлагаются большие надежды как на перспективный источник дополнительных инвестиционных ресурсов для реального сектора экономики особенно когда вынужденные локдауны из-за пандемии Covid-19 приостановили значительную долю активности реального сектора экономики во всем мире. Автором сделан вывод о том, что, исходя из преимуществ эмиссии долговых ценных бумаг, в долгосрочной перспективе все большее количество компаний будут выбирать данный вид финансирования своей деятельности в качестве основного.
Learning from Fiction to Change our Personal Narratives

Published: May 2021

Can fictional literature help us lead better lives? This essay argues that some works of literature can help us both change our personal narratives and develop new narratives that will guide our actions, enabling us to better achieve our goals. Works of literature can lead us to consider the hypothesis that we might beneficially change our future-oriented, personal narratives. As a case study, this essay considers Ben Lerner’s novel, 10:04, which focuses on humans’ ability to develop new narratives, and which articulates a narrative that takes into account both everyday life and large-scale issues like the global, environmental crisis.
Fuzzy logic: A tool to predict the Renal diseases
Authors: Sharma Pardeep Kumar , Sachdeva Amit , Bhargava Cherry
Published: May 2021

Clinical judgements can be improved by the use of artificial intelligence (AI) in the routine examinations. In case of chronic kidney diseases (CKD), it is quite difficult to detect at the early stages and afterwards the patient’s condition worsens very quickly. This is only because of the non-prominent disease specific symptoms at the early stages. An early prediction of AKI and CKD with machine learning can be a key to diagnose and reduces the cost of treatment. By using medical data mining of renal patients an intelligent decision support system (DSS) is designed using MATLAB environment, which enables the user to predict the various condition with maximum accuracy of prediction; whether the disease occurs or not and if yes then what is its severity.

Skin acts as a protective barrier of body. It keeps the internal body organs safe from external environmental conditions which can prove harmful for them. So, maintenance of skin integrity is very important for normal functioning of body. In our daily life body of both animals and humans encounter to different types of violence, some of them are of such a severity that they break the skin continuity. This breakage of skin continuity is termed as wound. Whenever, the skin continuity is broken, internal organs of body are exposed. This is a dangerous situation and can be fatal for life. Immediate response of skin after wound is the start of wound healing process which starts automatically. This process can be assisted in a number of ways by keeping the wound free from bacterial contamination, moisture and dirt. For this purpose a variety of antiseptic dressings are available which when applied topically support wound healing process. They prevent wound to be contaminated by any micro-organism and reduce wound healing time. Aloe vera is one of them, it possess significant wound healing properties. Herbs have been integral to both traditional and non-traditional forms of medicine dating back at least 5000 years. Herbal medicines, especially in wound management involve disinfection, debridement and provision of a suitable environment for aiding the natural course of healing. The super focus of this review is to summarize the findings of earlier scientists with authentic concluding verse for utilization of herbal medicines (Aloe vera) being safe, readily available and cheaper.
Review A Short Review of Promoters of Cotton Fibre Genes: Strength and Tissue Specificity
Authors: Masood Ammara , Iqbal Nadia , Mubeen Hira
Published: May 2021

Promoters are of great importance for controlling gene expression. There are various regulatory regions within promoters which are crucial for expression specificity. Depending upon mode of expression, promoters can be divided into constitutive, tissue/developmental stage specific or inducible promoters. For expression of certain gene, there is interplay of cis acting element located on promoter and transcription factors. Cotton fibre promoters are of great importance in biotechnology as these may be used to express fibre genes in cotton fibres specifically. Although most of cotton fibre gene promoters show expression in fibres but some of them also exhibit expression in various other organs like trichomes, pedicles and vascular tissues. Due to difficulties in somatic embryogenesis in cotton, these promoters are mostly studied in heterologous systems like Arabidopsis and tobacco. In this article, expression pattern of some cotton fibre genes promoters have been reviewed.
Effect of Solid to Water Ratio, Time and Temperature on Aqueous Extraction of Gallic Acid from Labisia pumila var alata of Malaysia
Authors: Salehan Noor Adilah Md , Naila Aishath , Ajita Azilah , Sulaiman Ahmad Ziad
Published: May 2021

Labisa pumila var alata contains bioactive compounds such as gallic acid that is of use for pharmaceutical and nutraceutical industries. Aqueous extraction is the traditional method that extracts phytochemicals from plant material. The study aimed to find the optimum condition for maximum gallic acid yield from ground L. pumila leaves using aqueous extraction. The results revealed that the maxium gallic acid yield obtained was at 1:10 sample to water ratio for 8 h at 50 °C. The maximum yield of gallic acid obtained was 1.025 mg gallic acid per g dried leaves (mg/g). The identification of gallic acid was done on Liquid Chromatograph Mass Spectrometer Quadrupole Time-of-Flight (LCMS-Q-TOF) by comparison to that of reference standard. The morphological structure of the extract that was obtained at optimum condition showed less denaturation of cell wall which indicates that still some gallic acid could be trapped in the sample matrix and other methods need to be employed to release them.
Exploring the Relationship Between Land Surface Temperature and Land Use Change in Lahore Using Landsat Data
Authors: Nasar-u-Minallah Muhammad
Published: May 2021

The present study focuses on determining the correlation of land surface temperature (LST) with normalized difference builtup index (NDBI) and normalized difference vegetation index (NDVI) of Lahore, a metropolitan city of Pakistan using landsat 5 and 8 dataset. This study also categorizes different types of land use through supervised image classification scheme and maximum likelihood algorithm (MLA), and assess the correlation between LST and land use type of different classes. The results of the study indicate that modifications in type of land use altered spatial variations of land surface temperature in 1990 and 2015. The findings also show that the ever increasing temperature caused by impervious surfaces such as builtup area, roads, construction sites and vacant land considerably contributes to heat island effect. However, vegetation cover, green and blue spaces decrease LST and effectively relieve the effect of heat island. LST builds a strong positive correlation with NDBI and strong negative correlation with NDVI. Based on the regression analysis between LST and NDBI and NDVI, these indices can be utilized as a sign to assess the impact of LU changes on temperature. The results further indicates that LST changes follow the pattern of LU changes in Lahore and the warmness intensity has been observed highest in the high density builtup area and vacant land, while low at the green and blue spaces. The analysis reveals that an increase in LST by 1.98 °C during the period of 25 years at the rate of 0.079 °C/year in high density builtup area was due to the excessive increase in settlement growth. The study concludes that change of land use has an effect on the LST in Lahore.
Martian Aerodynamics with PyFR
Authors: Roca Lidia Caros
Published: May 2021

Martian atmospheric conditions are very different to those on Earth, and present various challenges when designing rotorcraft. Specifically, Mars has a thin atmosphere with lower density compared to Earth. Additionally, the speed of sound on Mars is approximately 72% of that on Earth due to its low surface temperature and atmospheric composition, which puts a limit on rotor speeds in order to avoid high Mach numbers at the blade tip. Taken together, these conditions require Martian rotor blades to operate in a low-Reynolds-number (1,000 to 10,000) compressible flow regime; for which conventional aerofoils have not been designed. Recent studies by Munday et al. and Koning et al. have investigated the performance of aerofoils with flat surfaces and sharp leading edges under Martian atmospheric conditions. These aerofoils induce a higher adverse pressure gradient at their leading edge compared to conventional aerofoils, which can in turn lead to shedding of coherent vortices that do not trigger transition, but mitigate flow separation. In this talk I will present results from our latest GPU-accelerated high-order accurate Direct Numerical Simulations (DNS) of flow over a triangular aerofoil under Martian atmospheric conditions using PyFR, and compare them with results obtained for a triangular aerofoil in the Mars Wind Tunnel at Tohoku University. The importance of span and end-wall effects will be demonstrated. Finally, I will present our latest results from preliminary efforts to optimise a triangular aerofoil for Martian atmospheric conditions using Genetic Algorithms and GPU-accelerated high-order accurate DNS via PyFR.
Cache Blocking Strategies Applied to Flux Reconstruction
Authors: Akkurt Semih
Published: May 2021

On modern hardware architectures, the performance of Flux Reconstruction (FR) methods for tensor product elements can be limited by memory bandwidth. In general, these methods are implemented as a chain of distinct kernels. Often, a dataset which has just been written to main memory by a kernel is read back immediately by the next kernel. The accepted solution for such a redundant expenditure of memory bandwidth is kernel fusion. However, on a practical level kernel fusion requires that the source for all kernels be available, thus preventing calls to certain third-party library functions. Moreover, it can add substantial complexity to a codebase. An alternative to full kernel fusion is using cache blocking strategies, which has become practically possible in recent years due to growth in the size of CPU L2 cache. In this approach, kernels remain distinct, and are executed one after another on small chunks of data that can fit in the cache, as opposed to on full datasets. These chunks of data stay in the cache and whenever a kernel requests access to data that is already in the cache, memory bandwidth is saved. In this talk, a variety of kernel grouping configurations will be presented for FR based Euler and Navier-Stokes solvers, alongside associated theoretical memory bandwidth savings, and actual achieved performance gains when implemented in the PyFR solver. Inviscid and viscous Taylor-Green Vortex test cases are used as benchmark for Euler and Navier-Stokes solvers, and the most performant strategies lead to a speedup of approximately 2.63x and 3.01x, respectively.
CA 125 Modifications Throughout Menstrual Cycle and following GnRH-Analog Administration to Diagnose Endometriosis as Cause of Chronic Pelvic Pain. A Prospective Controlled Study
Authors: Venturella Roberta , D'Alessandro Pietro , Gallo Francesco , Morelli Michele , Zullo Fulvio
Published: May 2021

Purpose

Endometriosis is the leading single cause of chronic pelvic pain (CPP). To date, the gold standard to diagnose this condition is histologic confirmation of lesions obtained by surgery. However, a noninvasive and cheaper tool for early diagnosis is strongly needed. The aim of this study is twofold: first, to assess the diagnostic accuracy to detect endometriosis of serum CA 125 modifications throughout the menstrual cycle, and second, to analyze whether variations in CA 125 levels following one dose of GnRH-analog (GnRH-a) may increase the diagnostic value of the assay.

Methods

84 women scheduled for a diagnostic laparoscopy for CPP (group A) and another 12 women scheduled for diagnostic laparoscopy for unexplained infertility (group B) were enrolled as cases and controls. Serum CA125 was determined for each patient at the early follicular and luteal phases. Prior to surgery, patients from group A received one vial of leuprolide acetate depot. Following laparoscopy and histologic examination, cases were sub-grouped into group A1 (subjects with endometriosis) and group A2 (subjects without endometriosis).

Results

Plasma CA125 levels during the early follicular phase were significantly higher than those recorded in the luteal phase in all groups and they were significantly higher in group A1 in comparison with groups A2 and B. One month after GnRH administration, a significant reduction in plasma CA-125 levels was only observed in group A1.

Conclusions

The assessment of serum CA 125 modifications throughout the menstrual cycle and following one dose of GnRH-a demonstrated good diagnostic accuracy to detect endometriosis in patients with CPP. Women with endometriosis are characterized by a significant increase in CA125 levels during the early follicular phase and by a significant decrease following GnRH-a administration.

The present study aimed to evaluate the anthelmintic effect of Carapa guianensis (andiroba) on gastrointestinal nematodes in sheep naturally infected in the Western Amazon. Toxicity tests with Artemia salina identified that the ethanolic extracts of the root and stem of andiroba showed an LC50% equal to 530 μg ml-1 and 170 μg ml-1, respectively. As concentrations 1.06mg / ml (andiroba root) and 0.34mg ml-1 (andiroba stem) were tested in groups of crossbred sheep, eaten from four to six months and weighing approximately 19.9 kg naturally infected by gastrintestinal nematodes. In addition, there will be a total of two treated groups and two control groups (negative and positive - 7.5% closantel). Foram extracts applied orally in a single treatment days 1,2,3,4,15,16,17,18. Or treatment lasted 30 days. Samples of fezes and blood foram collected at intervals of seven and 15 days respectively to assess the parasitic and hematological profile. The results showed a reduction in parasitic load of 86% and 59%, respectively, for the root and stem of andiroba in egg count per gram of feces, while in the group treated with closantel 7.5% the reduction was 66%. Regarding the number of third stage larvae recovered from sheep after treatment, it was observed that the groups treated with andiroba root and stem differed (p < 0.05) from the control group, with a reduction in the percentage of larvae from 70 and 55%, respectively. The phytochemical tests in the present study revealed the presence of bioactive metabolites that may be responsible for the anthelmintic activity. As for the hematocrit, there was no statistical difference in its values in the groups treated with andiroba root and stem, that is, in some way there was interference on the adult forms of the nematodes that compromised the hematophagism. Therefore, the extract of Carapa guianensis has anthelmintic potential, being a good alternative in the control of sheep endoparasitosis.
The Daniel Narratives (Daniel 1–6): Structure and Meaning
Authors: Golan Naama
Published: May 2021

This article presents a new structural analysis of the Daniel narratives in Chapters 1–6. This structure is based on a new reading of the Daniel narratives from a perspective that emphasizes the tension between earthly and divine rule. Rather than focusing on the conflict between the Jewish courtier and his environment, the article highlights his internal identity conflict—he is caught between his loyalty to God and that to the king. The article thus sheds new light on the Daniel narratives in general and specifically on Daniel 1.

This volume focuses on Henry Aubin's thesis in The Rescue of Jerusalem: The Alliance between Hebrews and Africans in 701 BC (2002) that an army of Egypt's Kushite Dynasty (also known as the Twenty-fifth Dynasty) was influential in saving Jerusalem from capture by Assyrian forces. Eight scholars from a range of disciplines—biblical studies, Assyriology, Egyptology and Nubiology—assess the thesis and explore related ideas. Most of the evaluators tilt in varying degrees toward the plausibility of the book's thesis. The volume concludes with Mr. Aubin's response to each essay.
Jonah 2: A Death Liturgy for the Doomed Prophet
Authors: Kozlova Ekaterina
Published: May 2021

The use of fauna- and flora-based symbolism in ancient lament literature is a well-attested phenomenon. This article focuses on this symbolism in Jonah 2, exploring nature’s ritual agency in preparing Jonah for his entombment in the heart of the sea. In conclusion, the article considers how Jonah 2 can serve as an interpretive lens for Jonah 3 and 4, particularly their views on death and life.
Perceived Learning Outcomes and Interaction Mode Matter: Students’ Experience of Taking Online EFL Courses During COVID-19
Authors: Cui Yaqiong
Published: May 2021

The recent health emergency has changed the teaching mode globally, with traditional classroom teaching shifting to online platforms. This created challenges for both foreign/second language teachers and learners. Some recent studies investigated the challenges brought by online teaching from the teachers’ perspective; however, little is known about how students perceive the effectiveness of online language learning based on their experiences. Therefore, this study surveyed 252 Chinese students who took online EFL courses during the pandemic through an online survey platform. Survey questions include 75 statements regarding EFL learner’s perceived experience in taking online EFL courses, such as learning platforms, teaching and assessment methods, interaction mode, classroom management, and the effectiveness of online courses. Students rated each statement on a 5-point Likert Scale. Open-ended questions further targeted students’ suggestions to improve the quality of online language courses. Results from analysis of variance, factor analysis, and multiple linear regression analysis showed that students perceived the interactional opportunity and learning outcome as the most important factors in their online EFL learning experiences. Students generally showed a positive attitude toward their online language learning experiences and a high level of participation in synchronized online EFL courses. They further suggested a mixture of traditional and online class as an ideal teaching model for EFL learning, especially in the face of public crisis. Findings from this study may shed light on language curriculum design, language teacher education, and educational technology.

Snap bean is a vegetable crop presenting high requirements of mineral nutrients, such as nitrogen (N). However, studies on the response of this crop to N fertilizationare scarce, mainly with determinate growth habit genotypes, making it difficult to manage thisnutrient supply. The aim of this study was to evaluate the nitrogen nutrition and the productive performance of snap bean withdeterminate growth habit as a function of N sources and rates. The experiment was carried out inpots, under greenhouse conditions, inaEutrophicRed Oxisolwith 36.60 g dm-3of soil organic matter content.The cultivar ‘Macarrãorasteiro’TopSeedwas grownin a completely randomized design at factorial scheme 3x4, with four replications. It was studied three sources of N (urea, ammonium sulfate and sulfammo) and four rates (0, 40, 80 and 120 kg N ha-1), applied20% at sowing time, 40% at 12 days after emergence (DAE) and 40% at 20 DAE.It was evaluatedthe N content of the index leafandtheNaccumulationinshoots, the plant height at the endof the cycle and the number, total fresh mass, mean fresh mass and mean length of pods.The N content of the index leaf and N accumulation in shoots were linearly increased by the N rates, regardless of the N source, while the plant height and the pod’s characteristics werenotinfluenced by anyof the factors studied

Published: May 2021

The production of passion fruit in commercial areas requires a good correction of nutrients in the soil, however, with nutritional restrictions it can cause symptoms of deficiency expressed mainly in the leaves and stems, which may appear spots, reduced growth, changes in the architecture of these organs mainly in the its size and shape. This work aimed to know the effects caused by the suppression of nutrients in passion fruit species with an approach on their development and leaf morphology. The experimental design was completely randomized (DIC) in a 2x6 factorial scheme where the first factor was composed of two passion fruit species: P. gibertiiand P. edulis, interacting with the availability of nutrients, that is, a control group with the supply of all nutrients, with nitrogen suppression (N); phosphorus (P); potassium (K); magnesium (Mg) and iron (Fe), totaling 12 treatments with four replications totaling 48 plots or plastic vessels per experiment. The species P. edulisshowed better responses to the variables of development andleaf morphology. The species P. gibertiiis more susceptible to nutrient deficiency and showed changes in the color and shape of its leaves with the restriction of nutrients. The nutrients Fe and Mg caused greater restrictions on the development and leaf morphology of passion fruit species. It is necessary to carry out a new study with the species P. gibertiiregarding the appropriate concentrations of N, P and K provided in planting and cover, as this species is used as a rootstock in commercial areas

La Ley General de Educación en la memoria: del reconocimiento a la negación
Authors: Delgado Granados Patricia
Published: May 2021

The aim of this paper is to analyze the process of the drawing up of the General Education Act (LGE), created under the Franco regime and implemented a few years before the Spanish transition. In order to do so, we pay special attention to the socio-economic moment in which the law was projected and to the different political tendencies that were emerging in the scenario of dictatorship and that would become more visible in the transition. The paper also examines the individual and collective experiences and strategies of other sectors of the population, showing how they swung from recognition to denial of the LGE. The law’s implementation was the result of a critical diagnosis of the education system that implied a need for decisive change in the situation of education, a change that could be achieved by setting legal conditions for the normalization of universal education in Spain. The starting point was the belief that improving education would lead to the socio-economic development of the country while at the same time resolving the situation of ideological, political and social conflict that persisted under the dictatorship and that would be solved, in part, after 1978.
