Romania has a relatively high diversity of plant species, including 3829 vascular and 979 non-vascular spontaneous plant taxa (species and subspecies). Due to uncontrolled harvesting as well as other causes, including climate change and ecological collapse, the speed of species extinction and the narrowing of the genetic base of plant resources has been reported as a critical issue. Therefore, the national Red List of Romanian flora includes 1453 threatened taxa, of which 95 are endemic and 90 subendemic. Many of these have high ornamental, medicinal–cosmetic, and/or aromatic properties. The high extinction risk of these valuable plants has stimulated both the reconsideration of their vital importance as genetic resources and interest in finding effective methods for conservation. Cultivating these phytogenetic resources in a human-controlled environment is of high importance for effective ex situ conservation, which can further serve sustainable exploitation needs and may facilitate in situ conservation actions. In vitro culture is a powerful tool for producing elite plants for cultivation for different purposes. This review summarizes the current knowledge on in vitro multiplication of 22 endemic and subendemic native plants of Romania, examining the materials used, the treatments applied, and the results obtained in each stage of the micropropagation protocol (culture initiation, proliferation, rooting, and acclimatization). The findings from the reviewed studies are presented in a comparative way, and the potential of plant tissue culture in conservation and sustainable exploitation of these Romanian species is outlined.

Published: February 2023

Cattle manure usually contains a proportion of carbohydrates in the form of organic residues from incompletely digested feed and farm husbandry practices. These are not usually available for biogas production due to the long fermentation time. This paper investigates the optimal application of alkali, NaOH and KOH and mechanical pre-treatments to improve the degradation of the lignocellulosic content and the potential biogas yields from a local farm in Bavaria, Germany. Parameters such as temperature, pH, soluble chemical oxygen demand, organic acids, dry matter and volatile solids were analysed for this purpose. Alkali pre-treatments in 0.2, 0.1 and 0.05 M NaOH concentrations were tested in single mode and combined with shredding in batch experiments. The maximum increment of the soluble chemical oxygen demand during the pre-treatments took place during the first 50 h of experimentation, and it showed an improvement of 10,060.0 ± 8% mg/L s COD after the application of 0.2 M NaOH compared to the untreated substrate, which had an initial value of 2145.0 ± 8% mg/L s COD. Pre-treatments with 0.1 and 0.05 M NaOH concentrations showed similar s COD increments, with an additional 6860.0 ± 8% mg/L s COD and 8505.0 ± 8% mg/L s COD, respectively. The pH values varied strongly after the addition of the pre-treatment chemicals, with a continuous pH of 12 by 0.2 M NaOH during the 7 days of pre-treatment. Batch biogas experiments were done by applying 0.05 M NaOH and 0.05 M KOH pre-treatments in single mode and combined with shredding. The chemically pre-treated substrates showed a faster biogas production with an advantage of 18 days in comparison to the untreated cattle manure by a biogas yield of 350.0 NL/kg VS. All experiments were done under mesophilic conditions.

Published: February 2023

Thermal waste transformation plants (waste incineration plants) are a strong architectural accent in the existing site context. They often function as power plants or combined heat and power plants, producing heat and/or electricity by recovering energy from flue gases. The main objective of this study was to demonstrate the relationship between the architectural quality and protection of the natural environment through the technological solutions applied. The indirect aims of the study include the demonstration of the educational message conveyed through architectural and environmental solutions. The relationships defined by the objective were verified in comparative studies of eight operating waste incineration plants in Poland, located in: Bialystok, Bydgoszcz, Konin, Krakow, Poznan, Rzeszow, Szczecin, and Warsaw. The results were presented in three problem areas: (i) architectural quality, (ii) environmental solutions, and (iii) educational message. The results of the study led to the following conclusions: (i) waste incineration plants operating in Poland show a relationship between the architectural quality and broadly understood pro-environmental solutions, (ii) and all waste incineration plants operating in Poland show educational solutions.

Published: February 2023

The relevance of selecting an appropriate bed material in fluidized bed gasification is a crucial aspect that is often underestimated. The ideal material should be economical, resistant to high temperatures and have small chemical interaction with biomass. However, often only the first of such three aspects is considered, neglecting the biomass–bed interaction effects that develop at high temperatures. In this work, olivine and K-feldspar were upscale-tested in a prototype fluidized bed gasifier (FBG) using arboreal biomass (almond shells). The produced syngas in the two different tests was characterized and compared in terms of composition (H2, CH4, CO, CO2, O2) and fate of contaminants such as volatile organic compounds (VOCs), tar and metals.. Moreover, the composition of olivine and K-feldspar before and after the biomass gasification process has been characterized. The aim of this work is to show which advantages and disadvantages there are in choosing the most suitable material and to optimize the biomass gasification process by reducing the undesirable effects, such as heavy metal production, bed agglomeration and tar production, which are harmful when syngas is used in internal combustion engines (ICE). It has been observed that metals, such as Ni, Cu, Zn, Cd, Sn, Ba and Pb, have higher concentrations in the syngas produced by using olivine as bed material rather than K-feldspar. In particular, heavy metals, such as Pb, Cu, Cd, Ni and Zn, show concentrations of 61.06 mg/Nm3, 15.29 mg/Nm3, 17.97 mg/Nm3, 37.29 mg/Nm3 and 116.39 mg/Nm3, respectively, compared to 23.26 mg/Nm3, 11.82 mg/Nm3, 2.76 mg/Nm3, 24.46 mg/Nm3 and 53.07 mg/Nm3 detected with K-feldspar. Moreover, a more hydrogen-rich syngas when using K-feldspar was produced (46% compared to 39% with olivine).

Published: February 2023

Enterprise innovation is a key driver of national economic growth. How to stimulate employees’ innovation vitality to improve the company’s innovation input and output has always been a hot topic. Employee Stock Ownership Plan (ESOP) is one of the effective means to stimulate employees’ innovation vitality by linking employee wealth with firm value. The purpose of this paper is to examine the effect of ESOP implementation and contract design on enterprise innovation investment in the context of the recent booming development of ESOP in China. First, we use a treatment effect model to examine the impact of ESOP implementation on innovation investment, taking firms that implement ESOPs as the treatment group and firms that do not implement ESOPs as the control group. Second, we use multivariate regression models to test the impact of ESOP contract design (including fund source, stock source, lockup period, duration, shareholding scale, executive subscription ratio, participation degree, and management mode) on innovation investment using the treatment group. The results indicate that the implementation of ESOP is helpful in increasing enterprise innovation investment, and the impact of ESOP on innovation investment varies significantly with the design of incentive contracts.

Authors: Wang Hongyang , Li Baizhou
Published: February 2023

Digital innovation is the key for enterprises to obtain core competitiveness in today’s increasingly fierce market environment. Based on a sample of high-tech manufacturing companies listed in the Shanghai and Shenzhen A-shares from 2011 to 2020, this paper empirically tests the impact mechanism of the synergic influence of digital capabilities and technological capabilities of enterprises on digital innovation by using static panel regression, dynamic panel regression, and the moderation of social capital on their relationship. The results show that the synergic influence of digital capability and technology absorptive capability has a positive correlation with enterprise digital innovation. The synergy of digital capabilities and technological innovation capabilities has a positive correlation with enterprise digital innovation. Social capital plays a positive moderating role in the impact of the two synergic influences on digital innovation. The results imply that strengthening the coordinated development of digital capabilities and technological capabilities is essential for enterprises to carry out digital innovation, which is of great significance for the high-quality development of the manufacturing industry.

Authors: Liu Zhizhong , Zheng Shuchi , Zhang Xinyu , Mo Long
Published: February 2023

With the improvement of the technology level and the prevalence of the concept of environmental protection, green finance has been gradually applied to the field of production and economic development. As an important measure of economic development, the export sector is inevitably affected by the development of green finance. However, using the high technology of exports to analyze the relationship between green finance and exports has not drawn much attention. Based on the panel data from 30 provinces in China from 2011 to 2020, this study empirically examined the impact of green finance as well as export technology complexity, by using a combination of fixed effects and mechanism analysis. The results show that green finance has a significantly positive impact on export technology complexity, which means that an increase in the depth of green finance can improve export product quality. In terms of regional heterogeneity, the impact of green finance on the high technology of exports is greater in the eastern region than in the central and western regions of China. In terms of the manifestation of green finance, the effect of green bonds on export technology complexity is greater than that of green investment and insurance. Green finance improves the export technical complexity through three intermediaries, such as green technology innovation, capital investment strength, and product upgrading capacity. This study highlights the importance of green finance and provides new methods for governments to assist in the formulation of policies that can improve export technology complexity.
Topological Structure of the Order Parameter of Unconventional Superconductors Based on d- and f- Elements
Authors: Yarzhemsky Victor G. , Teplyakov Egor A.
Published: February 2023

The superconducting order parameter (SOP) of a triplet superconductor UTe2 was constructed using the topological space group approach, in which, in contrast to phenomenological and topological approaches, the single pair function and phase winding in condensate are different quantities. The connection between them is investigated for the D2h point group and the m′m′m magnetic group. It is shown how a non-unitary pair function of UTe2 can be constructed using one-dimensional real irreducible representations and Ginzburg–Landau phase winding. It is also shown that the total phase winding is non-zero in magnetic symmetry only. Experimental data on the superconducting order parameter of topological superconductors UPt3, Sr2RuO4, LaPt3P, and UTe2 are considered and peculiarities of their nodal structures are connected with the theoretical results of the topological space group approach.

Published: February 2023

We review the status of dark matter (DM) candidates in supersymmetric Twin Higgs models in light of the first results of the LUX-ZEPLIN (LZ) experiment. We found that, for twin bino-dominated DM, the new results strengthened the lower bound on the higgsino mass. However, a large part of the parameter space consistent with natural electroweak symmetry breaking is still allowed. In the case of twin-stau DM, the new results imply that, if the thermal abundance of the twin-stau LSP fits the observed density of DM, the twin stau cannot have a large left-handed component anymore.

The Dynamics of China’s Collaborative Innovation Network in Agricultural Biotechnology: A Spatial-Topological Perspective
Authors: Ma Hongkun
Published: February 2023

This paper explores the dynamics of the collaborative innovation network of China’s agricultural biotechnology, from a spatial-topological perspective. The data pertain to a collection of patent applications jointly filed by universities, research institutes and enterprises on the mainland of China during 1985–2017. Using the logistic model, we first identify the developing phases of China’s agricultural biotechnology. By dismantling the collaborative innovation network into spatial and topological networks, the dynamics are analyzed from these two dimensions at the three levels of nodes, edges and whole network. The results indicate that with the technology developing from the introduction to the growth-to-maturity phase, the collaborative innovation network exhibits dynamics as follows: as the scale expands, collaborations in the network are concentrated core cities, while dispersing to more innovators; enterprises replace universities and become the main innovation forces; the network attributes of small-world, scale-free and core-edge structures are apparent. Multi proximity factors including geographical, cognitive and organizational, play key roles in driving the dynamics, and the main factor evolves from geographical proximity to cognitive as well as organizational proximity.
An Empirical Study of A Smart Education Model Enabled by the Edu-Metaverse to Enhance Better Learning Outcomes for Students
Authors: Shu Xiaoyang , Gu Xiaoqing
Published: February 2023

The Edu-Metaverse, a vast ensemble of different technologies, has initiated a great and unprecedented change in the field of education. This change has been effected through the following Edu-Metaverse characteristics: embodied and multimodal interaction; immersive teaching scenarios, which can accelerate learning and skill acquisition; and the emergence of AI-enabled agents. In comparison to traditional classroom teaching models, smart education is a collaborative and visual model that adopts the latest AI technologies to reach a learning outcome. However, a problem that should be considered is how a smart education model, enabled by the Edu-Metaverse, can be developed to enhance better learning outcomes for students. Such a model should highlight smart pedagogy in the context of the Edu-Metaverse, together with a smart teaching environment, multimodal teaching resources, and AI-enabled assessment. In this study, we focused on the teaching of college English to 60 students from Zhejiang Open University. We investigated the effectiveness of a smart education model, which was empowered by the Edu-Metaverse, in enhancing better learning outcomes for the students, using a combination of qualitative and quantitative research. After the one-semester-long experiment, questionnaires were sent out to complement the interview findings. It was found that the students who engaged in the smart education model in the Edu-Metaverse yielded higher scores in oral English, vocabulary and grammar, reading comprehension, English-to-Chinese translation, and writing than those who engaged in traditional instruction. Therefore, this study suggests that a smart education model enabled by the Edu-Metaverse, which is characterized by a highly immersive experience, multimodal interaction, and a high degree of freedom for resource sharing and creation can help learners to realize deep learning, develop their capacity for high-order thinking, and help them to become intelligent individuals in an online learning space. In order to facilitate this smart learning, we make the following suggestions for educational institutions: (1) teachers should improve the design of teaching scenarios, (2) teachers should focus on learning assessment that is based on core literacy, and (3) teachers’ knowledge of the architecture of the Edu-Metaverse should be enhanced.

Published: February 2023

Road dust (RD), roadside soils (RS) and river surface sediments (sediments) are important materials for evaluating contaminant levels in urban areas. This study aims to investigate the contaminant characteristics, pollution levels and ecological risks of RD, RS and sediments of potentially toxic elements (PTEs), including Cr, Ni, Cu, Zn, As, Cd, Hg and Pb, in the central urban area of Zhengzhou. Results reveal that RD shows a higher concentration of PTEs when compared to the other two environments. The spatial distribution characteristics suggest that PTEs in RD, RS and sediments may come from different sources. The geo-accumulation index (Igeo) was used to describe that the RD was moderately to extremely contaminated with Cd and Hg, while both RS and sediments were significantly enriched with Cd and Hg. For RD, RS and sediments, the potential ecological risk (RI) demonstrates a high potential ecological risk from Cd and Hg. Overall, PTEs in Zhengzhou road dust present a moderate risk.
Ureteral Complications during Surgery
Authors: Dieter Raymond A. , Kuzycz George B. , Dieter William Jacob
Published: February 2023

Historically, ureteral complications during surgery have been occurring since the earliest performances of major abdominal or pelvic surgery. In the early 1960s, few diagnostic techniques were available to diagnose ureteral injury and determine the subsequent timely treatment required. Illustrations from two different time periods of possible operative ureteral injury, ligation, or transection following major complicated surgical procedures are presented, along with the diagnostic and therapeutic approach currently followed. The first individual had apparently sustained a ureteral injury during a prior surgical procedure, which, with limited diagnostic options, was not recognized until she visited us years later—as was the case for many early ureteral injuries. Major abdominal or pelvic surgery may be extensive and complicated, especially when dense fibrosis, scarring, and benign or malignant mass formation are present. Unfortunately, surgical complications, including bleeding and ureteral concerns, may develop during these extensive procedures. A more recent patient underwent major, life-threatening retroperitoneal surgery due to a chronic aortoenteric fistula (17 months total preoperative hospitalization elsewhere), during which the left ureter was transected. In our second patient, recognition and correction of the ureteral transection during the aortic surgery, upon completion of the aortic repair, prevented a potential major renal complication. The timely diagnosis of the operative ureteral injury and the repair prior to wound closure prevented major postoperative complications. As some physicians believe that surgically induced ureteral injuries are increasing in frequency, we present this report to enhance awareness of the possibility of injury and the potential value of recognition prior to abdominal closure. In addition, current operative and postoperative strategies available to identify and reduce potential ureteral injury complications when they occur are discussed.
Genomic High Plains Wheat Mosaic Virus Sequences from Australia: Their Phylogenetics and Evidence for Emaravirus Recombination and Reassortment

Published: February 2023

High Plains wheat mosaic virus (HPWMoV) causes a serious disease in major wheat-growing regions worldwide. We report here the complete or partial genomic sequences of five HPWMoV isolates from Australian wheat samples. Phylogenetic analysis of the nucleotide sequences of the eight genomic segments of these five isolates together with others from Genbank found all eight genes formed two lineages, L1 and L2. L1 contained a single isolate from Colorado in the North American Great Plains Region (GPR), and L2 had two unresolved clusters, A and B, of isolates from Australia and the GPR. A quarter of the L2B isolate sequences of the nucleocapsid gene (RNA3) were recombinant, which is unexpected as little evidence of recombination exists in viruses with negative single-stranded RNA genomes. Phylogenies calculated from the amino acid sequences of HPWMoV’s RNA-dependent RNA-polymerase (RNA1), glycoprotein (RNA2), and nucleocapsid protein (RNA3) showed they were closest to those of Palo Verde broom virus. However, its movement protein (RNA4) was closer to those of Ti ringspot-associated and common oak ringspot-associated viruses, indicating the RNA4 segments of their ancestors reassorted to produce the current emaraviruses. To avoid increased yield losses from co-infection, biosecurity measures are advised to avoid HPWMoV introduction to countries where wheat streak mosaic virus already occurs.

Published: February 2023

This study focuses on clarifying the regulation of chicken 14-3-3σ protein on the fibrous histiocyte proliferation caused by ALV-J-SD1005 strain infection. DF-1 cells were inoculated with 102 TCID50 of ALV-J-SD1005 strain; the cell proliferation viability was dramatically increased and 14-3-3σ expressions were dramatically decreased within 48 h after inoculation. Chicken 14-3-3σ over-expression could significantly decrease the cell proliferation and the ratio of S-phase cells, but increase the ratio of G2/M-phase cells in ALV-J-infected DF-1 cells; by contrast, chicken 14-3-3σ knockdown expression could cause the opposite effects. Additionally, chicken 14-3-3σ over-expression could also dramatically down-regulate the expressions of CDK2/CDC2, but up-regulate p53 expressions in the DF-1 cells; in contrast, the knockdown expression could significantly increase the expressions of CDK2/CDC2 and decrease p53 expressions. It can be concluded that chicken 14-3-3σ can inhibit cell proliferation and cell cycle by regulating CDK2/CDC2/p53 expressions in ALV-J-infected DF1 cells. ALV-J-SD1005 strain can promote cell proliferation by reducing 14-3-3σ expressions. This study helps to clarify the forming mechanism of acute fibrosarcoma induced by ALV-J infection.

The article shows that the development of a gifted personality depends on a number of factors of cultural determination. The global dynamics of social transformations, high social mobility, and intensive communication force us to constantly rethink the changing reality, overcoming the situation of uncertainty and discomfort. Exploratory behavior is a necessary condition for the development of the potential of an innovative personality, since it is directly related to the semantic processes. The highest form of cognitive activity and exploratory behavior is scientific cognition. That is why the introduction of project-research technology into modern school education is effective for solving the problems of educating a gifted individual. This article is devoted to the issue of development and transformation of the space of personal meanings in research activities. Its purpose is to analyze the impact of the research activities of a teacher and a student on the processes of rethinking (meaning formation, meaning generation, meaning change, meaning creativity) both in discovering knowledge for oneself and in self-construction of the hierarchy of personal meanings. This process is connected with the issue of self-determination and constant creative renewal of the vision of one's own life.

Los barrenadores del tallo del género Diatraea son plagas importantes en el cultivo del maíz (Zea mays L.) debido a la dificultad que se tiene en su manejo, ya que éstas barrenan el tallo de la planta y es difícil de presenciar su daño. Los hongos entomopatógenos constituyen una opción para su manejo. Se evaluó la patogenicidad de dos cepas de Beauveria bassiana (BbP 001 y BbP 002) y una de Metarhizium rileyi (MrP 001) con el objetivo de seleccionar la más patogenica sobre larvas del cuarto instar de Diatraea grandiosella. Para determinar la patogenicidad de estas cepas, se empleó una concentración de 1x108 esporas mL-1 para lo cual se utilizó un diseño experimental completamente al azar con cuatro repeticiones, aplicando los tratamientos sobre trozos de tallos de maíz de 5 cm de longitud para posteriormente colocarles una larva a cada tallo (12 tallos y larvas por cada repetición, en total 48 larvas por tratamiento). La mortalidad se analizó mediante un ANOVA y una prueba de Tukey donde se observaron diferencias significativas (α = 0,05) entre los tratamientos, en el cual se presentó un porcentaje de mortalidad del 71%, 50%, 27% ocasionado por las cepas BbP 001, BbP 002, MrP 001 respectivamente. Se seleccionaron las cepas de B. bassiana para determinar la concentración letal 50 mediante un análisis PROBIT con el paquete estadístico SAS 9.0, se evaluaron las concentraciones (conidios mL-1) de 1x106, 1x107, 1x108, 4x108 y 7x108, la cepa más patogénica fue la BbP 001 presentando una CL 50 de 1.8x107 y una CL 90 de 1.3x109, mientras que la cepa BbP 002 fue menos patogénica con una CL 50  de 7.2x108 y una CL90 de 4.5x109. Con base en estos resultados se concluyó que existen hongos entomopatógenos presentes en forma natural que infectan a las larvas de D. grandioella que pueden ser aislados para emplearlos como fuente de control biológico.

Published: February 2023

Tolkaappiyam is a comprehensive text on grammar which contains total 1610 sutras in the nurpa meter, it contains three books such as letters, words and subject matter. Tholkaappiyar has explained about the various types of claims both internal and external in subject matter.  In particular, he points out the narration in the 15th song out of 34 songs. This article explains the way in which Natrinai songs are composed with special interpretations called narrations. M.S. Rabising explains narrations as follows. A narration where one of the characters is speaking directly to the audience is called poetry.  Subjective songs are classified as ``Talaivan Kootru'', a song that sounds like a boy speaking, and ``Thozhi Kootru'', a song that sounds like a friend speaking.  In Tiruvalluvar's Kamathuppal, this type of narration or conversationis very famous.  In subjective literature, the hero and the heroine are the main character for narration. Therefore, this article reveals the manner in which the narrators follow the internal norms by analyzing the hymns from the perspective of the performers during the times of love making.

In Kalingatupparani, Jyangondar explains about the eight realistic incidents. They are actions that are expressed in physical emotion are considered as truths. When an action is not expressed emotionally it can be considered. A woman crying to goddess and asking her husband’s body parts that have scattered in the battlefield is the touching scene in the story. In the text Muthuppei can be seen as bowing down at the feet of Goddess Kali and showing her sorrow. Soldiers seen swimming in the sea and running scared of their own shadows. Can hear news about naturalization. Heroic acts of a hero mutilating his own body parts can be seen. Many stories like wives treating the scars of war-wounded husbands are seen. Thus, the article explains the eight realistic incidents of Kalingatupparani in a psychological approach.

Published: February 2023

Sangam Tamil consists of three major parts viz., Poetry, Music, and Drama. This is something that no other language in the world has. Hence, Tamil can also be called Muthamizh (The three kinds of literature in Tamil). Drama, along with music, has been developing gradually since time immemorial. Theatrical music is a mirror of worldly events. The literature also makes it clear that the Tamils excelled in art and culture. Therefore, on the basis of literary references, Poetic Tamil, Music Tamil, and Drama Tamil are the three Tamils that make history in many aspects. This approach seeks to explain from a variety of perspectives the work done by Thavathiru Sankaradas Swamigal on Musical Drama Text, mention of literary dramas such as play and dance, and his contribution to Tamil music and drama.

If a man has good moral behavior then he must have been trained well by the elders. The virtues given by Auvaiyar in ‘Purananuru’ are to be followed by others to led a good life. Virtues among the people must be a natural outcome. When a person is hungry, he should be given food by the others. Giving food to others and satisfying a person’s hunger is a kind of virtue. Virtue is the primary source of all human needs. Auvaiyar points out that one who have good thoughts and moral behavior will get plenty of goodness. Similarly, if the king of a country decides to help others, he will come forward to help no matter time or situation it is. The king thinks giving food and gifts to soldiers is the best virtue. At present people are selfish, they earn and spent it for themselves but the kings of Sangam period helped others by giving what they had. They are happy to help the needy. One should help others when they are in dangerous situation. The person who received the help will not forget it as long as he lives, charity is a gift, the land of the virtuous people will always be rich, king’s helping mentality and the nature of helping the needy are discussed well in this article.

En este trabajo se estudia la transformación microestructural de la aleación Al-Mg 20% peso, empleando tratamiento térmico de envejecimiento, con el propósito de que el contenido de magnesio modifique el endurecimiento por precipitación, para aumentar o disminuir la resistencia mecánica y la susceptibilidad a la corrosión. La experimentación consistió en realizar ensayos por triplicado, variando temperatura, tiempos de solubilización y envejecimiento; estos parámetros son los principales factores que causan el cambio microestructural, que afecta las propiedades mecánicas de la aleación. La microestructura y su variación morfológica fue caracterizada por ensayos de dureza, microscopia óptica y difracción de rayos x. Las muestras de Al-Mg 20% peso se calentaron a temperaturas de 190°C, 300°C y 350°C durante 6 horas. Los ensayos de dureza Brinell revelaron que la dureza es directamente proporcional a la temperatura a la que fue sometida cada muestra. La difracción de rayos DRX mostró la evolución microestructural y las fases presentes en la aleación binaria. La influencia de las condiciones del tratamiento térmico en la aleación Al-Mg 20% permitió encontrar distintas morfologías de precipitados, que se relacionan con las propiedades electroquímicas de la aleación, las cuales permiten relacionarlas indirectamente con la susceptibilidad a la corrosión de esta aleación binaria.
