Published: September 2022

A comparative evaluation of the effectiveness of the industrially produced oil spill dispersants (Finasol OSR 52 (France), Slickgone NS and Slickgone EW (United Kingdom)) was carried out. The effectiveness of dispersants was assessed using three samples of domestic crude oil with different physical and chemical properties (extra light, heavy, and bituminous oil) in water samples of various salinity. An adapted version of ASTM F2059–17 «Standard Test Method for Laboratory Oil Spill Dispersant Effectiveness Using the Swirling Flask» (the so-called SFT test) was used for evaluation. The low-energy technique was chosen to determine conditionally lower limits of the dispersant effectiveness. Comparative tests were carried out at the highest dispersant-to-oil ratio 1:10 allowed in the Russian Federation (according to STO 318.4.02–2005 «Rules of dispersant application for oil spill response»), water temperature 20°C and water salinity 0, 5, 10, 20, and 35‰. It is shown that the dispersants are poorly effective in dispersing the considered oil samples at water salinity 35‰. A general trend of increasing the dispersant effectiveness with a decrease in water salinity is demonstrated. It is shown that all tested dispersants are not suitable for application in the studied range of water salinity in the event of spill of the bituminous oil with a high content of asphaltenes and polar compounds. For all dispersants, the limits of their application are determined depending on the salinity of water. The effectiveness value equal to 45 % legally approved in the USA and Mexico was taken as a threshold value. The revealed lack of the dispersant versality necessitates preliminary experimental testing using a sample of spilled oil under climatic and hydrochemical conditions corresponding to the potential area of their application.

Nowadays, the transition from shaped casting to the methods of selective laser sintering and selective electron beam sintering (SELS) has been implemented for a number of materials. The thermophysical properties of materials play a decisive role when designing and modeling heat and mass transfer processes during powder sintering by additive technologies and monitoring the stability of the operational properties of final products. We present the results of studying the thermophysical properties of the samples of heat-resistant intermetallic titanium γ-alloy obtained by shaped casting and SELS in the range of 200 – 900°C. The characteristic DSC curves of the images and experimental temperature dependences of the heat capacity and thermal conductivity are presented. Comparative analysis of sample density measurements was carried out before and after thermal exposure. Analysis of the results obtained revealed a similar nature of the temperature dependences of the specific heat capacity and thermal conductivity of the samples produced by the methods of shaped casting and SELS. The presence of thermal stresses was observed when measuring the thermal expansion coefficient in the samples obtained by shaped casting. However, leveling of the stress state by additional thermal exposure led to identical values of the thermal expansion coefficient for the samples obtained by both methods. The results obtained can be used to improve the methodology for modeling heat and mass transfer processes during sintering of metal-powder compositions.
Computation and experimental analysis of the resistance of superalloys to low cycle deformations
Authors: Gadenin M. M.
Published: September 2022

Diagrams of cyclic elastoplastic deformation in a general case characterize the resistance of a material to a low cycle loading and display a relation between current values of stresses and strains during deformation process. Those diagrams in the mechanics of deformation and fracture are described by rather complicated state equations with a nonlinear dependence on conditions and modes of loading including temperature, deformation rate, cycle form, type of the stress state, absolute size of sections, working medium, type of constructional material, etc. The entity of aforementioned factors affects a shape of the deformation curve (diagram) of the material and key parameters of the corresponding state equations, including basic characteristics of the mechanical properties, i.e., the elasticity module, yield point and ultimate stress, indicators of static and cyclic hardening. Experimental data on the kinetics of cyclic and one-way accumulated plastic strains in each loading half-cycle (cycle) obtained in static and low cycle tests of nickel superalloy specimens revealed that change in deformation characteristics exhibit a drastically nonlinear character in conditions of cyclic elastoplastic strain which is described on the basis of power equations and corresponding parameters of cyclic deformation diagrams. The parameters of those equations depend on the type of cyclically hardening/softening or stable material under deformation of the material in elastoplastic region. It is noted that resistance of materials to cyclic elastic-plastic strain can be described by a set of analytical expressions containing a kinetic function (which changes with number of loading half-cycles) in the form of power or exponential expressions depending on the cyclic properties and characteristics of the mechanical properties of the specific structural material. The obtained calculated and experimental data on the kinetics of strain of the alloy under study in conditions of cyclic elastoplastic loading, as well as on the parameters of the strain diagram (which are basic characteristics for the corresponding state equations) provide the possibility to take full advantage of using the deformation-kinetic criteria of damage accumulation under considered loading conditions to calculate the fatigue life of the structural elements manufactured from the alloy and operated, as a rule, under severe temperature and heavy-loaded conditions. The results of the experiments and calculations are given in the form of diagrams of cycle-by-cycle kinetics of the cyclic and accumulated plastic strains of the material for the soft and hard modes of loading in a wide range of test temperatures.

Published: September 2022

Para analizar el proceso de internacionalización (I) y sus resultados considerando escenarios, actores y perspectivas se inició un proyecto de investigación de largo alcance. La I se analiza a partir de los discursos de los gestores, académicos, estudiantes de una universidad pública de México, y de sus diversas manifestaciones en la práctica. Recientemente las instituciones de educación superior se han enfocado a fortalecer docencia, investigación y gestión de manera global buscando la excelencia, local, regional, nacional e internacional. Esto ha sido analizado y documentado con este proyecto. Se aborda ahora la Internacionalización en Casa (IC), la cual según Beelen, J. (2011), se introdujo en 1999 con el objetivo de hacer que los estudiantes fueran competentes interculturalmente e internacionalmente sin dejar su propia ciudad. La distinción de lo que ésta implica se hace necesaria para que los involucrados utilicen los términos con precisión y con un mismo sentido, además de que posibilitará, como señala De Wit (2011), el no perder de vista la importancia de volver al origen y fijarse con detenimiento en el qué, el por qué y el cómo de la internacionalización. El análisis de la información recolectada a través de cuestionarios en línea se realiza considerando categorías como: Conciencia internacional y destrezas interculturales, vinculación entre los niveles de política, planeación y proyecto (dimensión vertical); lo académico, lo administrativo y lo operativo (dimensión horizontal) y los rasgos: sistémica, inclusiva en su implementación y articulada a todos los niveles estratégicos de la vida académica universitaria. En este trabajo se presentan los hallazgos y análisis de los ítems relacionados con conciencia internacional y destrezas interculturales, la perspectiva de docentes y estudiantes.

Published: September 2022

Actualmente la educación básica enfrenta diferentes retos para mejorar la calidad, desde focalizar la atención en sus procesos de gestión escolar, hasta el papel de los docentes dentro del aula. Sin embargo, uno de los elementos fundamentales para el trabajo docente y directivos es el papel que juega la planeación; entender su concepto, tipología y quehacer en el contexto educativo favorecerá los procesos de cambio que tanto se requieren dentro de las escuelas. La responsabilidad es de todos los que participan en el colectivo docente para definir y plantear las acciones de mejora a corto y largo plazo, pero es el liderazgo educativo quien orientará y establecerá la organización del plan estratégico institucional con base en las prioridades y necesidades de su entorno educativo.

Published: September 2022

It is critical and timely to investigate how teachers implement the 2015 revised mathematics curriculum in their classrooms as it has been applied to all elementary to high school grade levels in 2020. For this reason, we aimed to examine limitations that teachers perceived in their implementation of the 2015 revised mathematics curriculum in terms of curriculum documents, classroom environments, and education policy. We first conducted focus group interviews with 4 mathematics education professors, 5 elementary, 7 middle, and 5 high school teachers to find shared issues related to curriculum implementation. Next, the nation-wide field survey was designed using the limitations raised in the focus group interview to examine overall opinions about those issues. We collected the survey responses from 258 elementary, 185 middle, and 139 high school teachers. The results showed that descriptions of the mathematical competencies in the curriculum documents should be more clarified in connection to achievement standards. It is also suggested to include more applicable instructional guidelines in the curriculum documents. Teachers mentioned that ways to implement the process-focused assessment should be described in detail, but they generally agreed to remove differentiated instructions by students’ achievement in the documented curriculum. Furthermore, teachers highlighted demands for improved learning environments for educational technology as well as alignment between the revised curriculum and other education policies like the free-semester system. These findings suggested an implication about how to support teachers to implement the 2015 revised mathematics curriculum appropriately: A teacher manual for curriculum implementation, software and applications, and classroom materials should be provided with an easy access. It is additionally suggested that participation of in-service teachers are important in not only constructing practicum-centered professional development but also better implementing of the 2015 revised mathematics curriculum.

Published: September 2022

This study aims to analyze how 9th grade students participate in their online mathematics lessons implemented in school mathematics. We especially focused on the differentiated features that appear when students participate in online mathematics lessons. We identified various features provided by online lessons through theoretical review and designed lessons based on these features as follows. Students could participate in lessons through written interactions based on anonymity, visit and use various internet sites and software such as statistical analysis program, and participate in multi chat rooms. We had designed lessons that require these interactions and the utilization of online resources. The results were as follows: First, various online resources such as Tong-Gramy and interactions with peers supported students to collect and analyze the authentic data. Second, written interaction and multi-logue allowed students to get out of time and space constraints and provided students with the opportunities to participate in mathematical discussions performed in other groups. Written interaction also provided an opportunity to expand mathematical thinking through expanding teacher’s support. Third, the anonymity promoted students to participate in interactions more actively and strengthened the discussions focused on the mathematical ideas.

Authors:   The Korea Society Of Educational Studies In Mathematics, Kang Yunji , Chang Hyewon
Published: September 2022

In math problems, the pictures are often presented along with the text of the problem. The pictures in math problems play various functions to help or sometimes interfere with students' problem-solving. In order to examine the functions of pictures for successful problem-solving, functions of the picture presented in the first-year mathematics workbooks, the problem-solving process of the 3rd graders, and their perceptions were analyzed. The result of the analysis shows that the functions of pictures were widely used in the order of information, organization, representation, and decoration in both the first and second semesters. In addition, the number of pictures used in the second semester decreased compared to the first semester, and informational pictures appeared the most in all content domains. As for the perceptions of 3rd graders about pictures, they responded that pictures help solve problems in the order of informational, organizational, representational, and decorative functions, which is consistent with the degree of their contribution to problem-solving. Moreover. the problem including the picture was preferred regardless of the function of the picture. Based on the results of this analysis, some didactical implications were proposed for including the pictures in the math textbook or workbook and for using the pictures to guide students to problem-solving.

La agricultura convencional se fundamenta en un sistema de producción dependiente de alto uso de insumos sintéticos y hoy enfrenta dificultades para mantener niveles aceptables en la producción agrícola debido al aumento de los costos y contaminación ambiental. Una alternativa sustentable es el uso de bacterias promotoras del crecimiento vegetal, siendo una alternativa potencial al usarlas como biofertilizantes. El objetivo del trabajo fue evaluar cepas de Bacillus subtilis y Bacillus amyloquefaciens nativas de la región lagunera, probando su potencial como biofertilizante en el cultivo de maíz forrajero y evaluando rendimiento de materia seca. En los tratamientos se aplicaron bacterias de manera individual, en combinación entre ellas y con 50% de la dosis de fertilizante químico recomendado, las variables evaluadas fueron: área foliar, peso de hojas, peso del elote, peso de la caña, diámetro del elote, largo del elote, rendimiento de materia seca, desplazamiento de volumen de raíz, peso fresco de raíz y peso seco de raíz. El rendimiento de materia seca en los tratamientos con Bacillus no resultaron con diferencia estadística significativa comparado con el testigo químico, pero los tratamientos con bacterias resultaron mejores numéricamente. De la misma manera, se observó un aumento en la masa radicular en estos tratamientos, por lo que se considera su uso como una alternativa viable para sustituir el fertilizante químico.

Authors: Alam Ashraful , Hoque Md Mahmudul
Published: September 2022

Responsive governance during the COVID-19 pandemic became a severe challenge for countries worldwide. With a relatively poor healthcare structure, Bangladesh performed moderately well in managing the first wave of the pandemic (March – December 2020). With substantive policy and decision-making support from the Centre, local governments collaborated with various relevant actors to enhance their pandemic- related services. In this background, this research used an integrative framework to study a case of local-level collaborative governance – the Saturia Model. Based on the authors' experience, reflections and review, this analysis explores various socio-economic and environmental factors behind the effectiveness of this collaboration in containment policies and providing support services to vulnerable groups. Findings indicate that coordination between state and non-state actors, resource mobilization, access and communication, community engagement and the adaptative capacity of the government are vital for making such collaborations work in a crisis. The lessons are valuable for prospective understanding and policy interventions.

Published: September 2022

Objective We aimed to investigate the improvement in sleep quantity and quality when clonidine was used in children and adolescents with insomnia. We also examined how sociodemographic characteristics such as age, sex, underlying psychological problems, and levels of depression and anxiety affected the effect of clonidine.Methods We retrospectively reviewed outpatients aged 6 to 24 who took clonidine due to insomnia from September 2019 to September 2021 at the Department of Psychiatry at Eunpyeong St. Mary’s Hospital of Catholic University. We used the Pittsburgh Sleep Quality Index (PSQI), Children’s Depression Inventory (CDI), and State-Trait Anxiety Inventory (STAI) for our study.Results A total of 62 participants were included in our study (34 females, mean age 13.94±4.94 years). After using clonidine, there was a significant decrease in PSQI components 1, 2, and 5, especially PSQI component 2. There was a greater decrease in sleep latency when clonidine was used in females, those aged between 13 and 24, those with mood/anxiety disorder or attention-deficit/hyperactivity disorder, those whose sleep latency exceeded 60 minutes at baseline, and those who used clonidine for more than 14 days. Those with higher STAI-Trait scores and CDI scores at baseline showed less improvement in total PSQI scores.Conclusion Considering that there are currently no Food and Drug Administration-approved sleep drugs for children and adolescents and no apparent difference in efficacy and safety among sleep drugs, we demonstrated that treatment with clonidine might be a good approach to improve sleep quality and quantity for children and adolescents.

Objective We aimed to examined the reliability and validity of Korean version of Social Distancing Phobia scale, and whether intolerance of uncertainty mediates the association of the general population’s social distancing phobia with viral anxiety and depression.Methods Through this anonymous online survey, we collected responses from 400 individuals in the general Korean population. Participants’ demographic information and rating scales scores, including the Social Distancing Phobia scale, Stress and Anxiety to Viral Epidemics-6 items, Patient Health Questionnaire-9, and Intolerance of Uncertainty-12 items.Results Confirmatory factor analysis showed a good model fit, and the Korean version of Social Distancing Phobia scale showed good internal consistency. Social distancing phobia was significantly correlated with age (r=0.213, p<0.001), viral anxiety (r=0.390, p<0.001), depression (r=0.244, p<0.001), and intolerance of uncertainty (r=0.323, p<0.001). A linear regression analysis showed that age (β=0.235, p<0.001), viral anxiety (β=0.281, p<0.001), depression (β=0.121, p=0.009), and intolerance of uncertainty (β=0.200, p<0.001; adjusted R2=0.246, F=33.6, p<0.001) predicted social distancing phobia. Mediation analysis revealed that viral anxiety directly influenced social distancing phobia (z=6.48, p<0.001), and intolerance of uncertainty partially mediated this association (z=2.92, p=0.003).Conclusion Social distancing phobia may cause psychological stress but may also increase adherence to physical distancing measures and prevent the spread of viruses.

Objective The Delirium Diagnostic Tool-Provisional (DDT-Pro) was designed to detect the presence and severity of delirium briefly and objectively regardless of psychiatric expertise. We translated the DDT-Pro into Korean and validated it in elderly Korean patients.Methods To validate the translation and evaluate inter-rater reliability, a psychiatric trainee and a research nurse independently assessed the same patients referred to the Department of Psychiatry. The results were compared with the reference evaluations performed by a psychiatrist using the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5).Results We enrolled 42 elderly patients. The Cronbach’s alpha coefficient were 0.839 (the trainee), 0.822 (the nurse). The Cohen’s weighted κ between the trainee and nurse, ranged from 0.555±0.102 to 0.776±0.062. The Pearson correlation coefficients (Korean version of the DDT-Pro [K-DDT-Pro] and Korean version of the Delirium Rating Scale-Revised-98 [DRS-R98-K] total score) were γ=-0.850 (the trainee), and γ=-0.821 (the nurse). The areas under the ROC curves (AUCs) were 0.974 (the trainee) and 0.893 (the nurse).Conclusion The K-DDT-Pro exhibited high internal consistency and relatively substantial inter-rater reliability. The correlation with the DRS-R98-K was strongly negative. The accuracy of the K-DDT-Pro was excellent, regardless of expertise. In conclusion, the K-DDT-Pro is a brief and simple tool that usefully screens for delirium in elderly patients.
Use of marble dust containing filler mixture in composite slab production: Relationship between roasting conditions and physical properties of the slab

Published: September 2022

Marble dust generated during slab cutting as reject causes significant environmental problems due to increased reactive surface area. It has closer size distribution with micronized quartz filler used in composite slab. Owing to its high hardness, micronized quartz production is an energy intensive process. This study was conducted to investigate the applicability of marble dust in composite slab production together with micronized quartz as filler. The filler mixture was roasted to mitigate drawback arising from low hardness of marble dust. XRD characterization revealed that phases in roasted filler were wollastonite, larnite, calcio olivine, quicklime and free quartz depending on the roasting temperature and time. Physical tests were applied to clarify the effect of sinter phases on slab properties. Physical properties were determined to retrogress as the roasting temperature increased to 1100°C possibly due to rate of free lime in roasted filler, and then improved again reaching peak point at 1200°C. They ameliorated by increasing roasting time at 1200°C. Larnite and quartz were determined to be effective on improved physical properties than wollastonite and calcio olivine.
The Role of Positive Psychological Capital in the Prediction of Teachers’ Well-being Mediated Through Motivation: A Review of Literature
Authors: Tareke Zewude Girum , Hercz Maria
Published: September 2022

Based on the self-determination and positive psychology theory, teachers’ motivation links the relationship between psychological capital and teacher well-being and discusses their theoretical and practical benefits. It is argued that the scientific literature from wide-ranging and diverse studies on teachers’ well-being in elementary and secondary school focused on the pathological lens and healing specific disorders under a variety of life course threatening conditions across cultural contexts. Seligman (2011) criticised that mental health professionals and psychologists gave much prominence to mental disorders and pathologies, overlooking two crucial missions in the field of psychology: (a) helping healthy people to be happier and more productive and (b) actualising human potential. Depending on the current recommendation of positive psychology, and based on the literature gap and relevance of the issues, this study used a theoretical model of self-determination theory of motivation (Ryan and Deci 2017), psychological capital (Luthans et al. 2007a); hedonism well-being (Diener 2009a); and teacher well-being (Collie et al. 2015). Thus, in this review, the operational definition, components and measurements of positive psychological capital, teacher well-being and motivation of teachers and their link strongly supported with scientific literature and a future testing model was proposed. In this study, the links between each construct were addressed, and their educational implications to teachers, students, educational settings and policymakers are presented. Keywords: subjective well-being, teacher well-being, positive psychological capital, motivation
“German Pamphlets, Russian Chronicles, and Ivan the Terrible”
Authors: Halperin Charles J.
Published: September 2022

Many historians have questioned the accuracy of the “Tale of Ivan IV’s Campaign against Novgorod in 1570.” Cornelia Soldat now expands that critical approach to the “Tale” by arguing that it derives from German pamphlets published a century earlier. She relies upon the congruence of macro- and micro-structures to demonstrate textual influence without textual borrowing. Given the absence of Muscovite manuscripts of the “Tale” between 1570 and the second half of the seventeenth century, the composers of the “Tale” “must have” relied upon foreign sources about the raid, because no domestic sources existed. Her analysis is certainly possible, but it elides a number of issues about the transmission and translation into Russian of the German pamphlets. Reliable contemporary Muscovite sources tells us more about the “real” raid than Soldat allows. It is equally possible that the “Tale” derives from circulating native oral legends. However, the methodological and evidentiary issues Soldat raises are serious and deserve further discussion.
Making an Anti-Hero or Describing a Tyrant? Postmodernism and Ivan the Terrible
Authors: Filyushkin Alexander
Published: September 2022

Historiography of the study of Ivan the Terrible’s times contains many examples of demystification attempts: E. Keenan declared the correspondence between Ivan the Terrible and Andrey Kurbsky to be apocrypha, Anthony Grobovsky exposed the ‘Chosen Rada’, Mikhail Krom unmasked the time of ‘boyar rule’. Cornelia Soldat suggests revising the history of the ‘massacre of Novgorod’ in 1570. She believes it to be a product of a ‘literary game’. The story of the destruction of Novgorod first appeared in the German Flying Leaf in 1570 and Alexander Guagnini’s Chronicle in 1578. It was a product of European political discourse. The Novgorod Chronicles borrowed that story from Guagnini’s Chronicle in the late 17th century. However, this hypothesis lacks sufficient proof. Independent evidence exists: The Solovetsky Chronicle of the 16th century. According to Soldat, the reports from The Novgorod Uvarov Chronicle date back to the late 16t–early 17th (about 1606) centuries, rather than to the 17th century. The main argument against her concept is the confirmation in independent sources and documents of the death of many people, while the circumstances of the repression or death point to Novgorod and 1570. The Novgorod chronicles contain no evidence of text borrowings from German or Polish sources. There is no proven textual similarity between them. The story of the ‘massacre of Novgorod’ evolved in the Novgorod’s urban legends. This would have been hardly possible, if this story had been of a purely bookish, literary origin. Therefore, Cornelia Soldat’s attempt to demystify the history of the ‘massacre of Novgorod’ in 1570 cannot be considered convincing.

Herbal medicines are an important and growing part of International pharmacopeia. Research and testing enhance our understanding of their medical properties, making them a safer alternative or preferable option to allopathic medication. Plant-derived pharmaceuticals are gaining popularity due to the belief that "green medicine" is safer and more trustworthy than expensive synthetic drugs. This study aimed to evaluate the antimicrobial and anticancer potential of the methanolic leaf extract of Artemisia absinthium against human lung cancer A549 cell line by well diffusion method and MTT assay, respectively. The A. absinthium leaf extract showed the highest activity against Enterococcus faecalis (20 ± 0.7 mm), and Escherichia coli (18 ± 0.8 mm), followed by Pseudomonas aeruginosa (16 ± 0.6 mm), Candida albicans (14 ± 0.9 mm) and Staphylococcus aureus (13 ± 0.8 mm), with MIC values 128, 128, 128, 256 and 256 µg/mL respectively. The methanolic extract of A. absinthium showed significant (p ≤ 0.05) cytotoxicity against the A549 cancer cell line with an IC50 value of 36.8 µg/mL. The present study's findings give strong evidence for using the methanolic leaf extract of A. absinthium as an effective ethnomedicinal agent and a possible candidate for treating various human diseases and a potent bioactive agent in anticancer medications.

Biochar has gained attention in agricultural studies due to its ability to ameliorate soil conditions. However, due to its low nutrient content, positive effects on plant growth are generally only observed if combined with mineral fertilizers or manures. The study aimed to test the hypothesis that biochar used to treat domestic wastewater can become enriched with nutrients and subsequently serve as a better soil amendment. The impact of the application of biochar used as substrate in a filter for domestic wastewater treatment (TB) on the growth of  lettuce (Lactuca sativa var. crispa)  plant was evaluated. Its effect on plant growth was compared to pure biochar (BC) using bare soil as a control. The biochars were applied with and without fertilizer using 3 biochar application rates (10, 20 and 30 t/ha). Results showed that biochar does not become enriched after wastewater purification in the short run. Instead, there was a reduction in the mineral composition, available phosphorus and pH in TB compared to BC. Only the BC treatments were significantly different (p=0.001) from the control. However, higher biomass production at 30 t/ha was observed in BC (+322%) and TB (+142%), compared with the unfertilized control. There were no significant differences in biomass production between the biochar and control treatments for application rates below 30 t/ha. Fertilization significantly (p=0.024) improved biomass production with the BC30+F treatments demonstrating the highest performance (+315%) compared to the fertilized control.

Legumes play an important role in India’s food security, inflation rate and export values. Climate variability might significantly affect the growth, development and yield of legume crops in various regions of the globe. The present study investigated the long episodes effect of high temperature and CO2 and ambient conditions on leaf photosynthesis and yield attributes of green gram (Vigna radiata) using soil plant atmospheric research (SPAR). Green gram was grown under high day temperature (HDT) (day maximum temperature + 3oC) and elevated CO2 (600ppm) (HDT and eCO2), high day and night temperature (HDNT) (day maximum temperature + 3oC) and elevated CO2 (600ppm) (HDNT and eCO2) and ambient conditions. Leaf photosynthesis, stomatal conductance, transpiration rate and chlorophyll index were significantly (p=0.05) increased by 25%, 24.1%, 23% and 4.6%, respectively, under HDT and eCO2 from 30 to 45 DAS (days after sowing) in comparison with ambient and HDNT and eCO2. The significant increase in number of flowers shed per plant increased under HDNT and eCO2 by 13% during 45 to 60 DAS. The increase in the number of pods per plant and grain yield per plant under HDT and eCO2 during 45 to 60 DAS by 26.9% and 25.7%, respectively. However, the biomass of the green gram was increased under HDNT and eCO2 during 30 to 45 DAS. These studies indicated a significant increase in leaf photosynthesis and yield of green gram under HDT and eCO2 at flower initiation to pod development stage (30 to 60 DAS) followed by HDNT and eCO2 and ambient condition. Overall study indicated that increasing temperature and CO2 would increase the biomass and yield of the green gram.

Published: September 2022

In this article, multilayer nanowires (Ag/Co/Zn) were produced by electrochemical deposition in the form of anodic aluminum oxide. The electrochemical deposition method to produce nanowires are performed by three different methods. We have examined the pulsed periodic method, and we have managed to fabricate the nanowires of Ag/Co/Zn. Then, the produce nanowires are confirmed by the SEM and XRD analyses. Anodic nanoporous alumina with a thickness of 205 nm and a distance between pores of about 250 nm is produced by combining hard and soft anodization. Two-step anodization method including soft anodization and hard anodization was performed. These two anodizations were performed using 0.3 M oxalic acid as electrolyte at 0 degrees Celsius and applying voltages of 40 and 130 volts, respectively. Then the potential was reduced from 130V to 12V to thin the barrier layer. Multilayer nanowire arrays had been electrodeposited into the pores of anodic aluminum oxide (AAO) template. The electrochemical impedance spectroscopy has been carried out to study the in situ growth process of multilayer nanowires at different electrodeposition times.
Characterisation of phosphate mineralogy in Montebras-en-Soumans Pegmatite, Massif Central, France
Authors: Pirard Cassian
Published: September 2022

Montebras-en-Soumans pegmatitic cupola hosts large pods of phosphate composed of primary amblygonite-montebrasite. These aluminium phosphate masses are considerably altered by post-magmatic processes producing a number of secondary metasomatic hydrothermal phosphates (lacroixite, wardite, morinite, viitaniemiite, apatite, triplite, eosphorite) and low-temperature phosphates (apatite, crandallite, goyazite, gorceixite, variscite, turquoise, wavellite). Also found in this study are a Mn-rich viitaniemiite-like phase and an unknown Na-Al-P fluoride. A number of techniques are used to characterise these mineral phases including optical studies, cathodoluminescence (cold & hot), electron-probe micro-analysis (wavelength & energy dispersive spectra), X-ray diffraction, laser ablation inductively coupled plasma mass spectroscopy and infrared spectroscopy.
TempNet – Temporal Super Resolution of Radar Rainfall Products with Residual CNNs
Authors: Sit Muhammed , Seo Bong-Chul , Demir Ibrahim
Published: September 2022

The temporal and spatial resolution of rainfall data is crucial for environmental modeling studies in which its variability in space and time is considered as a primary factor. Rainfall products from different remote sensing instruments (e.g., radar, satellite) have different space-time resolutions because of the differences in their sensing capabilities and post-processing methods. In this study, we developed a deep learning approach that augments rainfall data with increased time resolutions to complement relatively lower resolution products. We propose a neural network architecture based on Convolutional Neural Networks (CNNs) to improve the temporal resolution of radar-based rainfall products and compare the proposed model with an optical flow-based interpolation method and CNN-baseline model. The methodology presented in this study could be used for enhancing rainfall maps with better temporal resolution and imputation of missing frames in sequences of 2D rainfall maps to support hydrological and flood forecasting studies.
