On the benefits of clustering approaches in digital soil mapping: an application example concerning soil texture regionalization
Authors: Dunkl Istvan , Ließ Mareike
Published: April 2021

Abstract. High resolution soil maps are urgently needed by land managers and researchers for a variety of applications. Digital Soil Mapping (DSM) allows to regionalize soil properties by relating them to environmental covariates with the help of an empirical model. In this study, a legacy soil data set was used to train a machine learning algorithm in order to predict the particle size distribution within the catchment of the Bode river in Saxony-Anhalt (Germany). The ensemble learning method random forest was used to predict soil texture based on environmental covariates originating from a digital elevation model, land cover data and geologic maps. We studied the usefulness of clustering applications in addressing various aspects of the DSM procedure. To investigate the role of the imbalanced data problem in the learning process, the environmental variables were used to cluster the landscape of the study area. Different sampling strategies were used to create balanced training data and were evaluated on their ability to improve model performance. Clustering applications were also involved in feature selection and stratified cross-validation. Overall, clustering applications appear to be a versatile tool to be employed at various steps of the DSM procedure. Beyond their successful application, further application fields in DSM were identified. One of them is to find adequate means to include expert knowledge.

Authors: Adelekan Saidi Adedeji , Erigbe Patience
Published: April 2021

The concept of organizational leadership has engendered a lot of arguments. This is because the effect of leadership on every human endeavor cannot be over emphasized. This study examines the effect of organizational leadership styles, particularly transformational and servant leadership styles on deposit money banks (DMBs) employees’ performance in Nigeria. The study employs survey research design, through the administration of structured questionnaire on some selected employees of Guaranty Trust Bank, United Bank for Africa and First Bank. The research instrument was validated through content validity index, while test-retest method was employed in ascertaining the reliability of the research instrument. The findings revealed that transformational leadership and servant leadership styles have positive and significant combined effect on deposit money banks employees’ performance (F-stat= 58.02 *0.000). The adjusted coefficient of determination (adjusted R2) suggested that, 39.4% variation in employees’ performance is accounted for by transformational leadership and servant leadership styles. The t-value revealed that when the two variables (transformational leadership and servant leadership styles) are combined, they both have positive and significant effect on deposit money banks employees’ performance. Therefore, it can be concluded that transformational leadership and servant leadership styles both have individual as well as combined positive and significant effect on deposit money banks employees’ performance.
Emerging Countries as the Main Destinations for European Value-Added Exports
Authors: Marti Luisa , Puertas Rosa
Published: April 2021

Nowadays, production chains may cross the borders of several continents in search of greater profitability. In order to more accurately calculate countries’ foreign demand, value-added exports should be used rather than gross exports. This study takes the value-added exports calculated for European Union countries and uses extended gravity models to analyze the determinants of this trade, differentiating between countries according to the main destinations for their value-added, USA, Russia and China. The results reveal certain changes according to the economic period analyzed and the destination of the goods, with respect to key variables such as the wealth of the exporting country, the level of logistics performance and distance. In 2014, China registered an improvement in its position compared to Russia.

In this paper, we detected and analyzed ionospheric anomalies during the 2016 super typhoons Megi and Meranti using the sliding interquartile range method applied to the ionospheric total electron content (TEC) grid data from the Global Ionospheric Model (GIM) provided by the Center for Orbit Determination in Europe (CODE). We found that ionospheric TEC anomalies occurred 2 days before the origination of super typhoon Megi. The anomalies occurred from 02:00 to 12:00 local time over a period of 10 h, with a maximum outlier of 12 TEC units over the typhoon center. Anomalies occurred in the ionosphere over both the area near the typhoon center and the corresponding equatorial magnetic conjugate region. The anomalies in both areas showed approximately the same trends. It is very likely that the disturbances from the ionospheric anomalies over the typhoon center were one of the precursors for the typhoon event. Similar ionospheric anomalies also occurred in the ionosphere 2 days before the formation and development of super typhoon Meranti...
On the Need to Reparametrize the OVATION Prime (2010) Auroral Precipitation Model
Authors:   Arctic and Antarctic Research Institute, Nikolaev A. V.
Published: April 2021

The need to reparametrize the OVATION Prime (2010) empirical auroral precipitation model using the Russian polar cap index (PC index) is considered. For this purpose, the integrated auroral power of particle precipitation obtained from the Polar satellite data for the period from December 1996 to June 1998 is compared with the PC index and the Newell’s coupling function. The analysis revealed that the PC index at the time delays up to 5–20 minutes correlates with the magnitude of auroral power much better (the correlation coefficient R ~ 0.76–0.87) than the Newell’s coupling function (R ~ 0.46–0.82). Thus, for the purpose of nowcasting the zone of active particle precipitation, the PC index showed much higher scores, although the predicting abilities of the Newell’s coupling function for the time delays of more than 20 minutes remain the best.

Haiku for recovery: An immersive workshop
Authors: Bullock Owen
Published: April 2021

Haiku are grounded in the appreciation of nature and specific experiences. They lend themselves to being workshopped and to initiating, more broadly, editing strategies that may also be useful in other contexts. This essay, about an immersive teaching practice, focuses on the qualities of haiku for maximum engagement in a short period of time. The method has been developed by the author whilst acting as a creative writing mentor for the Australian Defence Force Arts for Recovery, Resilience, Teamwork and Skills program at the University of Canberra, a partnership with the Australian Defence Force. Participants have had little or no previous exposure to haiku. The workshop is in four stages: a discussion introducing examples of haiku for discussion; a haiku walk; an editing session conducted on a large white board; and a “haiku checklist” to take away and continue working with. This checklist offers a core of information on writing haiku, distilled from the discussion of guidelines, which will be useful for teachers. The inclusion of a selection of examples from participants demonstrates how an immersive teaching process can instil the essentials of the haiku form in a relatively short span of time.

Extended confiscation is a personal security measure consisting in the forced and gratuitous transfer of property to the state patrimony, in the cases and under the conditions provided by law, which may be ordered in case of conviction of a person for committing a crime of a certain susceptibility to procure a material benefit, when the court is convinced that the goods in question come from criminal activities. The conviction of the court must be complete, based on the circumstances of the case, of specific facts, regarding the fact that the respective goods are the result of some criminal activities carried out by the convicted person. The evidence administered must not be capable of leading to the conviction of the defendant for these criminal activities as well, but it is sufficient to be such as to create in the court the conviction that the goods come from criminal activities. The property acquired by the convicted person during this period, but which is no longer in his possession or property, being transferred to third parties, if they knew or should have known [1] that the purpose of the transfer was to avoid confiscation, also fulfill this condition.

Theories and concepts in the psychology of education: development, education and learning
Authors:   University of European Studies of Moldova, Panczi Violina
Published: April 2021

Education is a determining factor for development, it deliberately aims to choose and accurately designate the perspective that will be instilled in development. Developmental psychology has made the leap from describing human life periods to identifying how certain factors influence these periods and what changes are taking place in increasing interest in the study of inter-individual differences. The development process is specifically organized, everything has a motivational basis, structure and a goal, purpose, or plan in relation to which it self-regulates. Development is as a set of transformations that affect living organisms or social institutions which also involves the notions of „continuity", „finality" and „evolution”.
Effect of Continuum Scattering on Early-type Supergiants Spectra
Authors: Nikoghossian A.
Published: April 2021

The effect of radiation scattering in continuum on the frequency distribution of the observed flux in atmospheres of supergiants of the late B and A spectral classes is treated. Thomson scattering on free electrons, which is important for hydrodynamic balance and wind dynamics in extended atmospheres of these stars, is considered as a specific scattering mechanism in the continuum. It is shown how stars of the same bolometric luminosity and with equal radii can belong to different spectral classes. The dependence of the continuum shortwave drift on the density of rarefied plasma has been established. The role of Thomson scattering in different domains of the hydrogen spectrum is revealed.

The paper deals with new layers of the systems Cr-Mo-Ni-Si and Cr-Mo-Co-Si bearing the common name "ChroSiMol". These layers are applied by means of atmospheric plasma spraying on metallic substrates of iron, nickel, cobalt, and titanium-based alloys and serve as corrosion, oxidation and wear protection for these metals at temperatures up to max. 900°C. The layer ChroSiMol is an acid-resistant layer and provides for its substrates a perfect protection against hot sulfuric acid and phosphoric acid in all concentrations. With a hardness of approx. 900 HV and very good anti-friction properties of the molybdenum-containing surface, these layers are optimally suited for use with friction pairs with corrosive loads.
Coatings of Carbide-Metal Systems (Cr3C2-NiCr and WC-Co-Cr) Deposited by High-Velocity Atmospheric Plasma Spraying from Specially Modified Fine-Grained Powders
Authors:   Thermico GmbH & Co.KG, Carlo-Schmid-Allee 3, 44263 Dortmund, Germany, Verlotski Vadim
Published: April 2021

In this article, the author poses and responds to a provocative question that has practically ceased to be asked in the field of thermal spraying of carbide coatings: Is the current worldwide trend of using only unmelted metal particles to form coatings (HVOF, HVAF and cold spray methods) correct, and is the deposition of completely melted powders (plasma spraying methods) really outdated? The results of high-speed plasma deposition of new carbide powders allowed the author to prove that only coatings from molten particles can solve the main problem of such coatings, namely the problem of permeability along the grain boundaries. Through the use of modern Axial III plasma torches combined with optimized fine-grained powders, it has been possible to create Cr3C2-NiCr as well as WC-Co-Cr gas-tight layers.

Published: April 2021

This research is conducted mainly to analyze the jet characteristics of various cold spray nozzles. This study presents the theoretical and practical aspects of Cold Spray process modeling, discusses multiple numerical analysis research areas, and determines the significant parameters to be considered while developing a custom cold spray setup and exhibits analysis-based correlations. The simulations were performed on some meshes of different density using the SST turbulent model in Star CCM+ solver. For the first time, in this work, the jet characteristics inside a step drilled nozzle was presented; Furthermore, shock diamond formation was found inside the divergent section of step drilled nozzle which strongly influence the flow regime with sharp fluctuations. The comprehensive comparison between step drilled nozzle, conical nozzle and curved nozzle indicates that curved nozzle results in slightly higher nozzle exit velocity. However, results have suggested that the curved nozzle can achieve much higher velocities by optimizing the nozzle length.

Published: April 2021

Vista la relevancia territorial de la producción ecológica en España y el contexto caracterizado por un fuerte aumento en la demanda interna de productos ecológicos, este trabajo tiene por objetivo estudiar en un ámbito local (ciudad de Lugo), los hábitos de consumo hacia los productos ecológicos. Se realizaron 177 encuestas personales directas a finales de 2019 a consumidores en tres tipos de establecimientos comerciales, mediante un muestreo aleatorio estratificado por sexo y edad de población.Los resultados confirman un gran conocimiento de lo que son los productos ecológicos, cuyo consumo se produce en 4 de cada 5. La mayor frecuencia de consumo es una vez por semana, siendo las frutas y verduras el producto más consumido. Factores como la edad, nivel de ingresos, formación, hábitos de vida se correlacionan con el consumo. El origen local del producto es el atributo al que el consumidor presta mayor atención y existe una predisposición a pagar un sobreprecio por un producto ecológico, de media del 44%.

El manejo sostenible de los agroecosistemas de dehesa es un desafío de gran importancia ambiental, social y económica en la península ibérica y en los territorios de clima mediterráneo en general. El manejo racional de los recursos forrajeros para el ganado juega en esto un rol preponderante tanto para la seguridad alimentaria presente y futura de la población, como para la conservación de especies vegetales y animales y la mantención de la fertilidad y calidad de los suelos y el agua, con todos los beneficios relacionados. El presente trabajo presenta una propuesta de planificación de pastoreo en dehesa para el rebaño caprino de la quesería "ComoCabras" en la provincia de Córdoba, Andalucía, España. Mediante entrevistas a expertas y visitas a experiencias, fichas de análisis y trabajo conjunto con las sostenedoras del la granja, se logró perfilar el diseño de la propuesta incluyendo análisis de factores y beneficios potenciales en lo ambiental, económico y social. Mediante esta propuesta se busca generar un aporte para este proyecto caprino en particular, y para otras iniciativas de planificación de pastoreo en climas mediterráneos, así como un caso de estudio que pueda ser útil en el diseño de políticas públicas de apoyo a la producción ganadera, proyectos de producción sostenible de alimentos y recuperación de agroecosistemas de alto valor socio-ambiental.

Nature is a sacred space, where the tradition and rituals of Afro-Brazilian religions are celebrated, which performance is essential for the preservation of natural resources. Traditional communities that practice Candomblé in Brazil are settled on Nature, so they value and maintain biodiversity. Our objective was to study the spatial evolution of the land use by the traditional African-based community that occupies the Quilombo AnastáciaSite, as well as to understand how their customs – related to the maintenance of health and food -and their rituals help in the conservation of agrobiodiversity. The monitoring of the evolution of land use was carried out using LANDSAT satellite images and images from Google Earth software. According to the timeline (elaborated for 1997-2019), there was substantial increase in vegetation cover. In addition, the planting of native trees, food and medicinal species, as well as the use of agroecological practices (such as implementation of agroforestry systems), promoted diversification in the property. The Quilombo Site area favors the maintenance of the people's health and dietary habits, and the culture of this traditional African-based community guided the occupation of the soil, in order to benefit the conservation of agrobiodiversity.

Equine raising is generally articulated as a secondary activity on farms, where animals are used for leisure or work. Thus, it is important to consider the health of these animals, seeking to understand which are the main agents that circulate in a given farm or region. In this sense, this study aimed to evaluate the presence of IgG anti-Sarcocystis spp., anti-Toxoplasma gondii, and anti-Neospora spp. antibodies in equines in western Santa Catarina, Brazil. A total of 100 serum samples from horses from 10 farms, located in the municipalities of Faxinal dos Guedes, Xaxim, and Xanxerê were analyzed from June to December 2019. The samples were evaluated by indirect immunofluorescence reaction (IIFR) to detect antibodies of IgG class against the three agents. The results showed that the equines in the region are seropositive against the three studied agents, 11% of which for Sarcocystis spp. 21% for T. gondii, and 20% for Neospora spp. The analysis of the presence of these protozoa in different environments showed that both stabled and extensively raised horses presented signs of contact with the studied agents. Animals that live only in stables had a higher occurrence of IgG anti-Sarcocystis (7/32; 21.88%) and anti-T. gondii (11/32; 34.38%) antibodies. The evaluating of animals raised on pasture, semi-extensively and extensively, showed a higher percentage of seropositivity for N. caninum (9/34; 26.47%). The high occurrence of animals seropositive to the studied protozoa reinforces the importance of controlling and preventing these agents in the region, as they have the potential to cause a high impact on equid farming, mainly involving reproductive losses and equine protozoal myeloencephalitis (EPM).

The aim of this study was to examine the use of antioxidants on the oxidative stability of poultry offal oil used in the pet food industry. Five commercial synthetic and two natural antioxidants were used in the following treatments: Control (CON); CON + (BHT + BHA + ETH95); CON + (BHT + BHA); CON + (BHA + PG + CA); CON + (BHT + BHA + ETH70); CON + BHA; CON + (ASC + rosemary); and CON + (ASC + tocopherols). Inclusion levels were 0.5% for the synthetic and 0.625% for the natural antioxidants. Oxidative stability was determined at three temperatures (90, 110 and 130 ºC). To determine the fatty acid profile, the original sample of the offal oil was considered a negative control. The fatty acids were determined based on the preparation of methyl esters by a transesterification reaction with methanol in alkaline medium, followed by gas chromatography analysis. The different fatty acid types were identified by comparing the retention times of the fatty acid methyl ester standards with the retention times of the observed peaks. Compositional data analysis was carried out. Without the use of antioxidant, induction time is shorter, resulting in lower oxidative stability of the offal oil and consequent loss of its quality due to less time taken to oxidize. The antioxidants used in CON + (BHT + BHA + ETH95), CON + (BHA + PG + CA) and CON + BHA better preserved the essential fatty acids (linolenic and linoleic). Natural antioxidants exhibited higher oxidation, with higher proportions of saturated fatty acids and the worst ω6:ω3 ratios. In conclusion, the synthetic antioxidants used in CON + (BHT + BHA + ETH95), CON + (BHA + PG + CA) and CON + BHA provided greater protection against oxidation and better preserved the essential fatty acids. The natural antioxidants tested in the present study did not provide satisfactory protection.

The objective of this study was to evaluate the influence of four water salinity levels on productive performance, physiological and behavioral responses of confined sheep. Thus, 24 crossbred sheep, ½ Dorper x ½ Santa Inês were evaluated while receiving ration and water ad libitum. The experimental design was completely randomized, composed of four treatments (1.5; 3.0; 6.0 and 9.0 dSm-1) and six replicates. The water supply with salinity of up to 9.0 dSm-1 did not affect (P > 0.05) the physiological indexes, performance, or ingestive behavior of the animals, which were able to maintain normal physiological conditions even at times when the thermal comfort indexes were above the ideal. For voluntary water consumption, it was observed that there was a significant difference between treatments (P < 0.05), where animals consuming water with a conductivity of 1.5; 3.0 dSm-1 had lower consumption than those who received six dSm-1. The supply of water with a salinity of up to 9.0 dSm-1 did not affect the performance or the ingestive behavior of the animals, so waters with this salinity can be a valid alternative for crossbred sheep in the semi-arid region, as long as it is used seasonally and strategically.

Published: April 2021

Oral cancer is a frequent head and neck cancer in developing countries and some developed world. According to the World Health Organization classification 2017, oral cancer influences the anatomical subsites including buccal mucosa, the anterior two-third of the tongue, lip, palate, vestibule, alveolus, floor of the mouth, and gingivae. A variety of premalignant lesions are related with the development of oral cancer, such as leukoplakia, erythroplakia, et al. The predominant histological type of oral cancer is squamous cell carcinoma (SCC). Tobacco and alcohol consumption are regarded as critical etiological factors. Due to the unspecific symptoms in early stage, the majority are diagnosed in advanced stages. Despite the development of medicine over decades, the mortality rate of oral cancer remains high, indicating the importance of optimized treatment and screening strategies.
