Symptom specificity of ayahuasca's effect on depressive symptoms
Authors: Gilbert Cody Sykes , Earleywine Mitch , Mian Maha N. , Altman Brianna R. 
Published: April 2021

AbstractBackgroundAyahuasca's effects on symptoms of depression have generated considerable optimism. Clients frequently report more concern about some symptoms than others, and available treatments alter symptoms differentially. Few studies address the symptom specificity of this psychoactive brew.AimsWe examined self-reported effects of ayahuasca on the individual symptoms of depression assessed by the 10-item short-form of Center for Epidemiological Studies of Depression (CESD-10).MethodsWe asked over 120 participants to complete a retrospective assessment of CESD-10 symptoms one month before and one month after using ayahuasca.ResultsParticipants indicated that ayahuasca had a larger influence on affective symptoms like hope, depressed mood, and happiness, than cognitive, interpersonal, and somatic symptoms like restless sleep, loneliness, and difficulty focusing.ConclusionsPotential clients might appreciate identifying if different treatments provide more relief for some depressive symptoms than others. We examined retrospective reports of ayahuasca's potential for differential impact. Those eager to alter hope, happiness, and other affective symptoms will likely find ayahuasca more helpful than those who want an intervention for restless sleep, loneliness, or trouble focusing. This symptom specificity parallels the effects of serotonergic antidepressant medications, suggesting that psychedelic-assisted psychotherapy using ayahuasca might have considerable appeal for those who seek comparable relief but would rather not use prescription serotonergic medications. Jumpstarting psychotherapy with the rapid onset of ayahuasca-induced relief also appears to have potential.

Authors: Paris Marta , Pérez Marcela , D'Elía Mónica 
Published: April 2021

El concepto de seguridad hídrica focaliza el objetivo de la gestión del agua en la sociedad. Sin embargo, en los ambientes urbanos -donde deben atenderse requerimientos relacionados al abastecimiento de agua, inundaciones, lluvias intensas, ascenso del nivel freático, problemas de contaminación, entre otros-, la falta de datos e información adecuadas a la escala de trabajo, e incluso el uso inapropiado de metodologías, atentan contra cualquier intento de mejorar esta capacidad de la población para hacer frente a las situaciones críticas. Incluso en las ciudades es más evidente que el desafío de lograr el equilibrio entre la oferta de agua –finita, vulnerable y variable-, y una oferta -incansablemente creciente, de múltiples usuarios e interdependiente-, obliga a “re pensar” el ciclo hidrológico como un sistema ambiental dinámico y con ello, a sumar a la Hidrología un enfoque interdisciplinar. En este trabajo se presentan las metodologías, resultados y conclusiones que han servido de base para mejorar el conocimiento de los sistemas acuíferos de las ciudades de Esperanza y Santa Fe (Argentina). La primera sustenta su abastecimiento con aguas subterráneas, con lo cual es indispensable la protección del recurso y las obras de captación. En el segundo caso, la interrelación entre el agua superficial y la subterránea es compleja y requiere que hidrodinámica del sistema en su conjunto deba ser considerada para definir las mejores alternativas tecnológicas de la infraestructura urbana y el manejo de las inundaciones. Los avances logrados señalan la importancia de la ciencia, como motor que genera soluciones efectivas para que la sociedad alcance las metas del desarrollo sostenible y la seguridad hídrica.
Horace R. Blank and the origin of rock doughnuts
Authors: Twidale Charles Rowland 
Published: April 2021

Rock doughnuts are annular rims developed around rock basins that intermittently carry pools of water. They are developed in granitic rocks, and in arenaceous and calcareous sediments and in coastal as well as interior settings. Rock levees are found adjacent to gutters but are of a similar nature and origin. Both doughnuts and levees can be attributed to the development of protective coatings or veneers by biota, and of silica, iron oxides, and carbonates by overflowing pool waters. Contrasts in drainage from regolithic covers, weathering at sheltered interfaces and variations in runoff can also be cited at causative factors and situations.
Nota sobre la última transgresión marina en la costa de Galicia
Authors: Grandal d’Anglade Aurora , Vidal Romani Juan Ramón 
Published: April 2021

Desde el final del Pleistoceno hace 12.700 años hasta el día de hoy se están produciendo efectos dramáticos en toda la orla litoral de la costa de Galicia debidos esencialmente al ascenso del nivel del mar en toda la costa con una velocidad media entre 3mm y 3,5 mm anuales desde el inicio del Holoceno y que se evalúa, aproximadamente, en unos 40,95 metros. El efecto inmediato ha sido una progresiva reducción de la anchura de una plataforma continental cubierta por playas y extensos campos dunares lo que produjo una migración hacia el continente de los depósitos arenosos movilizados por las olas (playas) y/o por el viento (dunas). En el momento actual se ha alcanzado prácticamente el límite del avance transgresivo holoceno al situarse el mar en la base de la costa rocosa acantilada o en su caso frente a alguna masa de agua dulce (ríos o lagunas costeras) que frena temporalmente el avance de las dunas o la acumulación de arenas de playa. La acción marina está procediendo a la destrucción acelerada de las playas donde el viento primero excava sus corredores de tormenta que luego el mar, durante los temporales, utilizará para invadir el interior del continente. En las zonas de costa rocosa la acumulación de la arena produce las características dunas rampantes o trepadoras. En este trabajo se aportan algunos datos de gran interés referidos a la exhumación de los niveles de antiguos bosques y su fauna asociada, presentes desde el inicio del Holoceno en la franja litoral, y que ahora, efímeramente, vuelven a ser puestos al descubierto antes de ser destruidos definitivamente por la acción de las olas.

Currently, practically the entire volume of water extracted in the process of hydrocarbon exploitation is utilized by injection into deposits. Changes in the physico-chemical parameters (pH, red-ox potential, temperature, etc.) of the water during extraction and the contact of the injected water with the native water and deposit rock may result in the precipitation of sediment particles and suspensions. It causes clogging of the near-wellbore zone and limits the amount of water that can be injected with the injection well. Due to the high complexity of the system: the injected water–reservoir rock, and a wide range of interactions between individual components, the analytical data does not always allow for the correct interpretation of the course of the processes and determination of their impact on the permeability of the near-well zone. Using the results of physico-chemical analyses of the composition of separator water samples with different properties – two samples with low mineralization S1K (575 mg/dm3) and S4K (551 mg/dm3), a sample with high S2K (306 428 mg/dm3) and medium mineralization S3K (79 858 mg/dm3) – calculations were performed using the PHREEQC program for the three databases: phreeqc.dat, wateq4f.dat and pitzer.dat. It was found that in the case of low mineralization waters, the results obtained in each of the databases are similar for the minerals present in all the databases. However, in the case of solutions with high mineralization, there are significant differences in the obtained results. The calculated solubility indices allowed to determine the direction of the precipitation/dissolution reaction of individual minerals in the deposit and to indicate the risks, mainly with the formation of iron compounds deposits, for the operation of the injection well. Laboratory tests of water mixing were also carried out. The formation of iron oxide deposits that could damage the near-well zone was observed, which confirmed the results obtained during computer simulations.
EDUCAÇÃO E LITERATURA: POR UMA ESTÉTICA DO ISOLAMENTO SOCIAL
Authors: Baptista Ana Maria Haddad 
Published: April 2021

A Educação, em tempos de isolamento social exigido pelo Corona Vírus 19, exige e exigiu uma nova postura de estudantes e professores. A ruptura brutal e sem precedentes no processo educacional possibilitou aberturas para discussões, a partir de livros e textos, e análises críticas, em especial da literatura, do contexto, assim como de situações existenciais. Professores e alunos viram, na prática, novas possibilidades de uma educação que possibilitou aberturas e estratégias que talvez nunca teriam sido pensadas. Este texto relata algumas experiências obtidas durante a fase da pandemia em cursos de graduação e pós-graduação stricto sensu. Nessa medida, em nossas experiências, procurou-se ressaltar a importância de caracterizar o período, assim como buscou-se leituras que, de alguma maneira, discutissem o contexto pelo qual estamos passando. Buscou-se, inclusive, a discussão de situações existenciais propostas pela literatura de Proust, Beckett, Marco Lucchesi, Emil Cioran e outros autores importantes. Conclui-se que houve uma recepção muito amistosa por parte dos estudantes que proporcionaram uma visão mais crítica em relação ao ensino remoto e que as artes, assim como a literatura podem ser instrumentos ferozes em busca de novos valores humanos e contextuais.
Special Issue on Novel Technology of Autonomous Drone
Authors: Suzuki Satoshi , Nonami Kenzo 
Published: April 2021

In the past three years, there has been rapid progress in the use of drones in society. Drones, which were previously used only experimentally in various industrial fields, are now being used in earnest in everyday operations. Drones are becoming indispensable tools in several industrial fields, such as surveying, inspection, and agriculture. At the same time, there has also been dramatic progress in autonomous drone technology. With the advancement of image processing, simultaneous localization and mapping (SLAM), and artificial intelligence technologies, many intelligent drones that apply these technologies are being researched. At the same time, our knowledge of multi-rotor helicopters, the main type of drones, has continued to deepen. As the strengths and weaknesses of multi-rotor helicopters have gradually become clearer, drones with alternate structures, such as flapping-wing drones, have come to attract renewed attention. In addition, the range of applications for drones, including passenger drones, has expanded greatly, and research on unprecedented drone operations, as well as research on systems and controls to ensure operational safety, is actively being conducted.
This special issue contains the latest review, research papers, and development reports on autonomous drones classified as follows from the abovementioned perspectives.
· Research on drone airframes and structures
· Research on drone navigation and recognition with a focus on image processing
· Research on advanced drone controls
· Research and development of drone applications
We hope that the readers will actively promote the use of drones in their own research and work, based on the information obtained from this special issue.
Newly Qualified Female Teachers’ Perception of Teaching Practicum as a Component of Initial Teacher Education in South Africa
Authors: Iwu Charmaine Helena 
Published: April 2021

This study was undertaken with the aim of understanding how newly qualified female teachers perceive teaching practicum in the South African context. Teaching Practicum is a vital component of the initial teacher education (ITE) programme because it enriches future teachers’ knowledge, skills and abilities towards a lifelong career in the teaching profession. Teachers make valuable contributions to the growth of any nation as they help produce future leaders. It is therefore necessary to have a competent teaching workforce to improve pass rates as well as reduce dropout rates among learners. The study took the qualitative deductive premise making use of semi-structured interviews to collect data from more than 30 novice teachers. Key words, which helped in the identification of themes, were distilled from the responses. A core overall finding of the study point to a mix of experiences - benefits and shortcomings - which not only affect the development of prospective teachers but also have profound implications for both policy enhancement and implementation. Regarding policy enhancement and implementation, it is suggested that universities and schools where novice teachers are posted for teaching practice should have good relations for support advancements. In this case, it is advised that the novice teachers should be exposed to critical mentoring opportunities to allow for clearer understanding of the real classroom scope. This study believes that for this to be fruitful, schools should among others be well-equipped. Suggestions for further research are also flagged.

Generalized Support Vector Machines (GSVMs) model for real-world time series forecasting
Authors: Ahmadi Mehrnaz , Khashei Mehdi 
Published: April 2021

Abstract
Support vector machines (SVMs) are one of the most popular and widely-used approaches in modeling. Various kinds of SVM models have been developed in the literature of prediction and classification in order to cover different purposes. Fuzzy and crisp support vector machines are a well-known branch of modeling approaches that frequently applied for certain and uncertain modeling, respectively. However, each of these models can only be efficiently used in its specified domain and cannot yield appropriate and accurate results if the opposite situations have occurred. While the real-world systems and data sets often contain both certain and uncertain patterns that are complicatedly mixed together and need to be simultaneously modeled. In this paper, a generalized support vector machine (GSVM) is proposed that can simultaneously benefit the unique advantages of certain and uncertain versions of the traditional support vector machines in their own specialized categories. In the proposed model, the underlying data set is first categorized into two classes of certain and uncertain patterns. Then, certain patterns are modeled by a support vector machine, and uncertain patterns are modeled by a fuzzy support vector machine. After that, the function of the relationship, as well as the relative importance of each component, are estimated by another support vector machine, and subsequently, the final forecasts of the proposed model are calculated. Empirical results of wind speed forecasting indicate that the proposed method not only can achieve more accurate results than support vector machines (SVMs) and fuzzy support vector machines (FSVMs) but also can yield better forecasting performance than traditional fuzzy and nonfuzzy single models and traditional preprocessing-based hybrid models of SVMs.

Published: April 2021

Abstract
The main objective of this study is to analyse the background and knowledge of Spanish dentists and stomatologists registered in Alicante, Castellón and Valencia, the three provinces that make up the Valencian Community, with regard to forensic dentistry and the current Spanish health legislation and regulations, and to try to quantify the relationship between level of training, specialisation, work experience, position and workplace, and degree of knowledge.An anonymous survey was designed and validated, consisting of thirty-three multiple-choice questions. The survey included questions regarding their professional background and key questions regarding current dental law, forensic science and expertise. Members' level of knowledge of legal and forensic dentistry, health legislation and regulations in the Valencian Community is moderate, with only 63% of the questions answered correctly. Neither their level of education nor work experience correlates significantly with their degree of knowledge. Dentists specialising in General and Aesthetics Dentistry were found to be more knowledgeable about ethical issues. Regarding the workplace, those working as university teachers tended to stand out from the other professionals in terms of legal and ethical knowledge whilst self-employed and employee dentists show a lower level of knowledge than the rest of the sample.The conclusions obtained from this study highlight the need for dentists to complete and update their knowledge of forensic science and current health legislation, as having proper knowledge is a means of avoiding possible legal problems, which not only means better legal protection for the dentist but is also a means of guaranteeing adequate patient care.

Abstract
Borassus flabellifer leaf extract has been used for rapid biogenic-synthesis of Zinc-Oxide nanoparticles (ZnO-NPs) due to rich source of bioactive compounds. The synthesized ZnO-NPs were preliminarily confirmed by UV-Visible spectroscopy adsorption peak range at 365nm. The XRD (X-ray diffraction) confirm purity of ZnO-NPs that were crystalline in nature. The analysis of FT-IR (Fourier-transform infrared spectroscopy) confirm the presence of following functional group such as alcohol, phenols, carboxylic acids, primary amides, secondary amides, alkyl halide. FE-SEM analysis indicated that ZnO-NPs were in spherical shape, followed by EDX analysis which confirmed the presence of Zn-element. Antimicrobial effect of ZnO-NPs was investigated using different clinical pathogens like bacteria Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Klebsiella Pneumonia, Pseudomonas aeruginosa and fungi Aspergillus flavus, Candida albicans and Penicillium expansum and which confirmed ZnO-NPs efficiency as an antimicrobial agent. Antioxidant activity were ascertained to used for several biomedical applications. The ZnO-NPs was efficiently degraded the environmental toxic dyes (methylene blue and crystal violet) under sunlight. In support of photolight-degradation, the study was progressed to understand the ZnO-dye interaction stability using molecular mechanism and it was showing efficient bonding features in the NPs environment. Overall, this investigation have great potential for being an effective and eco-friendly materials was used in environmental applications.
Pollution control mechanism analysis of thermal degradation of decabromodiphenyl ether by zinc oxide
Authors: Gao Lan , Lei Yuan , Li Zhansheng , Liu Peng Yan 
Published: April 2021

Abstract
Low brominated diphenyl ethers and brominated dioxins with high toxicity were easily produced in the pyrolysis process of decabromodiphenyl ethers, Based on this, the pyrolysis process of BDE-209 and ZnO was studied by differential thermal gravimetric analysis (DTA-TG), X-ray diffraction (XRD), GC and GC / MS. The results showed that the addition of zinc oxide reduced the activation energy of BDE-209 thermal degradation reaction, thus reducing the thermal degradation temperature of BDE-209; after the addition of zinc oxide, BDE-209 pyrolysis produced more brominated dioxins at 400 ℃ When BDE-209 and ZnO were degraded at 400 ℃ at 2.4:1 (w / W), the degradation rate reached 100% at 2 h. At this time, the relative content of hexabromo- and heptabromo- dioxins was lower, and the relative content of hexabromobenzene and pentabromobenzene was the highest. Combined with Arrhenius formula calculation, soft and hard acid-base theory and XRD product analysis of pyrolysis residue, the mixed pyrolysis mechanism of BDE-209 and zinc oxide was deeply discussed, which provided a theoretical basis for pollution prevention and control of waste printed circuit boards in heat treatment.
