Rediscovery, redescription and identity of Pristimantis nebulosus (Henle, 1992), and description of a new terrestrial-breeding frog from montane rainforests of central Peru (Anura, Strabomantidae)
Authors: Köhler Jörn , Castillo-Urbina Ernesto , Aguilar-Puntriano César , Vences Miguel , Glaw Frank
Published: June 2022

The taxonomic status of the strabomantid frog species Pristimantis nebulosus (Henle, 1992), originating from the southern Cordillera Azul in central Peru, is investigated based on examination of the holotype and its comparison with freshly collected topotypic material. Following current standards, we provide a redescription of the holotype. It is in a rather poor state and exhibits certain damages and preservation artifacts, conditions that have hampered an allocation of this nominal taxon to any known living population of Pristimantis in the past. Our detailed specimen-to-specimen comparison provided morphological evidence for the conspecifity of the holotype and freshly collected topotypes. Molecular phylogenetic analysis, based on the mitochondrial 16S gene fragment places P. nebulosus in the P. conspicillatus species group, being closely related to P. bipunctatus and an undescribed candidate species from the Cordillera de Carpish. From both, P. nebulosus differs by considerable divergence in the 16S gene (p-distance 4.1–6.2%). Based on the specimens available, we provide an updated diagnosis for P. nebulosus, compare it to other species in the P. conspicillatus group and describe its advertisement call. In addition, we describe and name the closely related candidate species from the Cordillera de Carpish. It is sister to P. bipunctatus and P. nebulosus, but differs from both mainly by its tuberculate dorsal skin (versus shagreen) and divergence in the 16S gene (3.3–4.1%). We briefly discuss cryptic species diversity in the P. conspicillatus and P. danae species groups and provide justification for the description of a singleton species.
On the asymptotic behavior of solutions for the self-dual Maxwell-Chern-Simons $ O(3) $ Sigma model
Authors: Chen Zhi-You , Wang Chung-Yang , Huang Yu-Jen
Published: June 2022

In this paper, we consider the nonlinear equations arising from the self-dual Maxwell-Chern-Simons gauged \begin{document}$ O(3) $\end{document} sigma model on (2+1)-dimensional Minkowski space \begin{document}$ {\bf R^{2,1}} $\end{document} with the metric \begin{document}$ {\mathrm {diag}}(1,-1,-1) $\end{document}. We establish the asymptotic behavior of multivortex solutions corresponding to their flux and find the range of the flux for non-topological solutions. Moreover, we prove the radial symmetry property under certain conditions in one vortex point case.
On the Campanato and Hölder regularity of local and nonlocal stochastic diffusion equations
Authors: Lv Guangying , Gao Hongjun , Wei Jinlong , Wu Jiang-Lun
Published: June 2022

In this paper, we are concerned with regularity of nonlocal stochastic partial differential equations of parabolic type. By using Campanato estimates and Sobolev embedding theorem, we first show the Hölder continuity (locally in the whole state space \begin{document}$ \mathbb{R}^d $\end{document}) for mild solutions of stochastic nonlocal diffusion equations in the sense that the solutions belong to the space \begin{document}$ C^{\gamma}(D_T;L^p(\Omega)) $\end{document} with the optimal Hölder continuity index \begin{document}$ \gamma $\end{document} (which is given explicitly), where \begin{document}$ D_T: = [0, T]\times D $\end{document} for \begin{document}$ T>0 $\end{document}, and \begin{document}$ D\subset\mathbb{R}^d $\end{document} being a bounded domain. Then, by utilising tail estimates, we are able to obtain the estimates of mild solutions in \begin{document}$ L^p(\Omega;C^{\gamma^*}(D_T)) $\end{document}. What's more, we give an explicit formula between the two indexes \begin{document}$ \gamma $\end{document} and \begin{document}$ \gamma^* $\end{document}. Moreover, we prove Hölder continuity for mild solutions on bounded domains. Finally, we present a new criterion to justify Hölder continuity for the solutions on bounded domains. The novelty of this paper is that our method is suitable to the case of space-time white noise.

Published: June 2022

Objectives: The Regional CardioCerebroVascular Center (RCCVC) project was initiated to improve clinical outcomes for patients with acute myocardial infarction or stroke in non-capital areas of Korea. The purpose of this study was to evaluate the outcomes and issues identified by the Busan RCCVC project in the treatment of ST-segment elevation myocardial infarction (STEMI).Methods: Among the patients who were registered in the Korean Registry of Acute Myocardial Infarction for the RCCVC project between 2007 and 2019, those who underwent percutaneous coronary intervention (PCI) for STEMI at the Busan RCCVC were selected, and their medical data were compared with a historical cohort.Results: In total, 1161 patients were selected for the analysis. Ten years after the implementation of the Busan RCCVC project, the median door-to-balloon time was reduced from 86 (interquartile range [IQR], 64-116) to 54 (IQR, 44-61) minutes, and the median symptom-to-balloon time was reduced from 256 (IQR, 180-407) to 189 (IQR, 118-305) minutes (p<0.001). Inversely, the false-positive PCI team activation rate increased from 0.6% to 21.4% (p<0.001). However, the 1-year cardiovascular death and major adverse cardiac event rates did not change. Even after 10 years, approximately 75% of the patients had a symptom-to-balloon time over 120 minutes, and approximately 50% of the patients underwent inter-hospital transfer for primary PCI.Conclusions: A decade after the implementation of the Busan RCCVC project, although time parameters for early reperfusion therapy for STEMI improved, at the cost of an increased false-positive PCI team activation rate, survival outcomes were unchanged.

Published: June 2022

En este trabajo abordamos la figura de la mística sor Beatriz María de Jesús (1632-1702), monja clarisa del convento del Santo Ángel Custodio de Granada, a través del estudio crítico de su biografía, escrita por fray Tomás de Montalvo. Se presta especial atención a su relación con la autoridad episcopal granadina, censora por inercia de cualquier clase de escándalo y siempre recelosa ante la manifestación de carismas místicos extraordinarios. Así, se investiga la causa de su progresivo reconocimiento por parte de la jerarquía eclesiástica y de su fulgurante éxito entre la sociedad granadina de la segunda mitad del siglo XVII.
The FABLAB Movement
Authors: Lena-Acebo Francisco Javier , García-Ruiz María Elena
Published: June 2022

The arrival of collaborative contexts to the global economic stage is a latent reality which threatens to change the traditional production models' operation. Likewise, concepts such as Industry 3.0 or even 4.0 refer to the possibility of providing customers and users with unimaginable possibilities compared to the industrial manufacturing inherited from the past centuries. Within this environment, the fabrication laboratories (FabLabs) emerge. In this chapter, the authors approach an exploratory perspective in order to make known the FabLab movement origin and further worldwide development with the intention to highlight their characteristics and the main difficulties they face nowadays. The growing importance that the FabLabs have achieved despite their novelty justifies the precise study of their characteristics according to the importance related to the strong expansion of these laboratories in this decade and its contribution to a major revolution in the collaborative environments associated with the digital manufacturing.
Dynamic Decision-Making Model
Authors: Steed Marlo Bruce
Published: June 2022

The purpose of this chapter is to inform educational practitioners as to possible frameworks and models for effectively integrating 3D printing into instruction. This will focus on the conceptual ideas that overarch and guide the decisions for integrating 3D printing in education. Educators need a critical perspective and rationale so that the novelty of the tool doesn't overwhelm sound pedagogy. An understanding of how the features of 3D printing match up with the attributes of instructional approaches is the key to designing and orchestrating effective learning experiences. This chapter describes a model of decision making that takes into account the affordances, constraints, and approaches of 3D printing and details the implications for learning activities. The decision-making model will enable educators to effectively integrate 3D printing into educational contexts.

This chapter addresses the process of creating cross-curricular projects in an online environment, specifically the considerations, constraints, and methodologies. It discusses how to approach this type of learning through the lens of students' technology literacies, providing meaningful connections to digital pathways with which students are already engaged and authentic learning. The chapter also describes a digital makerspace as an avenue for student learning to take place. Finally, the authors present a student project that represents a culmination of these techniques. The project uses the engineering design process to blend both science and English language arts practices using side-by-side inquiry and the digital makerspace as a presentation medium.
The CCAP Project
Authors: Angelopoulos Panagiotis , Solomou Efthalia , Balatsoukas Alexandros
Published: June 2022

The “CCAP” project is an effort to teach in an interdisciplinary way both the teaching subjects of History (the trip of Columbus to discover America) and Informatics (3D modelling and printing). Students of B grade from the Junior High School of Vrilissia (age 13), on a voluntarily basis, separated into groups of 4-6, have created in a 3D design environment instruments used by Columbus during its trip to America, astrolabes, compasses, caravels, etc., as were taught during the subject of History and according to the description of the instruments given by the school book and other resources. The instruments were eventually printed out using the 3D printer in the computer lab. Part of the program was supported through the school's curriculum hours, and part of the program had to be implemented out of school hours. After the completion of the project, students responded to a questionnaire prepared by the teachers in a Google form format. The most important results of this questionnaire are discussed in this work.
Effect of the Collaboration Between MakerSpace, University, and Elementary Schools on Student STEM Attitudes
Authors: Lyublinskaya Irina , Sheehan Stephanie
Published: June 2022

This chapter examines the effect of a STEM project developed in collaboration between MakerSpace, a public university, and a Title I elementary school on student STEM attitudes and interests in future STEM careers. There is limited research on the Maker Movement and practically no research on whether MakerSpace facilities and expertise can be effectively integrated into a standards-based elementary school curriculum. As part of this study, 5th grade students designed and built birdhouses to make connections between mathematics and science learned in the classroom and world around them. The study was conducted in urban settings, in a school with large percentages of at-risk students. Pre- and post-surveys were administered to measure student STEM attitudes, 21st century skills, and interests in future STEM careers. Results showed significant increase in scores in all these areas after students completed STEM projects. This study illustrates a successful collaboration between MakerSpace and local schools to enhance the standards-based school curriculum.
Manufacturing Education for Society 5.0
Authors: Loy Jennifer
Published: June 2022

The last 20 years have brought significant developments to digital fabrication technology, known as additive manufacturing (3D printing), and it has finally started to shed its prototyping mantel in favor of an industrial one. Yet its innovations are in danger of being subsumed into existing commercial practices, as society arguably continues to underestimate its ability, in conjunction with data collection, analysis, and communication tools, to disrupt current systems and enable a more equitable distribution of manufacturing wealth, capability, and capacity. This chapter highlights the potential of emerging industrial technologies to support a shift towards a more human-centered, responsible society where social and environmental problems are addressed through systems that maximises cyberspace and physical space integration, through the reframing of higher education engineering curriculum and pedagogy for manufacturing in Society 5.0.
Microhabitat selection by overwintering alder bark beetles (Coleoptera: Curculionidae: Scolytinae) on red alder (Betulaceae)
Authors: Wertman Debra L. , Borden John H. , Carroll Allan L.
Published: June 2022

The alder bark beetle, Alniphagus aspericollis (LeConte), is known to overwinter as larvae and adults in the main stems of red alder, Alnus rubra (Bongard). Observations of adult alder bark beetles in the branch and bud nodes of planted saplings during the winter led to the hypothesis that these microhabitats represent alternative overwintering sites for the beetle in mature trees. To test this hypothesis, we surveyed crown branches at three coastal British Columbia locations, sampling three trees in 2003 and 2004 and three additional trees (nine branches per tree) in 2018–2019. Adult beetles were found overwintering inside sites excavated in the branch and bud nodes throughout the crowns of mature trees. Branch type, defined by growth class, and tree affected the overall distribution and likelihood of overwintering site occupancy among the three trees sampled intensively in 2018–2019, whereas overwintering site age (old versus new (current year)) affected the frequency of site occupancy across all six trees. We suggest that overwintering in tree crowns evolved from late-summer maturation feeding in new shoots and that the majority of beetles abandon terminal shoots as temperatures fall, moving deeper into the crown to overwinter preferentially in older branch tissues that offer greater thermal protection.

Authors: Ekaye S. , Uwagie-Ero E. A. , Akanyeno F. E.
Published: June 2022

The aim of this study was to determine the effects of Alligator pepper, Aframomum melegueta, seed extract on wound healing in albino rats.  Four treatment groups of eight albino rats each were used for the experiment. Group 1 were given feed and water only. Group 2, 3 and 4 were exposed to a reference drug (Cicatrin), 10% and 20% of the extract respectively for 21 days. Excision wounds of 30mm were made on dorsal thoracic central region of the rats. Serum from blood collected from the dorsal aorta of sacrificed rats were analysed for oxidative stress biomarkers (TNF-α, MDA and SOD) using standard methods. The tissue samples from the wounds were collected and histhopathologically analysed under a light microscope. The decrease in wound size was measured using an electronic Vernier Calliper at intervals of two days. The values of TNF-α ranged from 87pg/ml to 136pg/ml while those of MDA ranged from 0.92 to 3.19µmol/L. The maximum and minimum values of SOD recorded were 25.15U/mg protein and 12.6U/mg protein respectively. The smallest wound size value, 5.5mm, was measured in Group 3 on day 19 of the experiment. Behavioural changes were observed which included lethargy and anorexia. The histopathological study of the extract groups showed the formation of new tissues, keratinized substances and hair follicle. The results obtained from the wound measurements supported the conclusion that the extract had a better effect on the wound healing in experimental animals.
Larvicidal Efficacy of Aqueous Extracts of Leaf of Ocimum gratissimum and Bark of Terminalia catappa against Aedes sp
Authors: Major G. O. , Omoregie A. O.
Published: June 2022

The resistance of vectors to conventional insecticides has resulted in a renewed attention to natural products such as botanicals as a means of controlling mosquito vector population seeing that they are readily available and are eco-friendly. This study investigated the larvicidal efficacy of aqueous extracts of Ocimum gratissimum (leaf) and Terminalia catappa (bark) against Aedes sp. larvae and the evaluation of the phytochemical constituents present in them. The extracts were tested on laboratory bred Aedes sp. larvae at different concentrations (500, 750 and 1000ppm) at 24, 48 and 72 hrs. Data was analysed statistically using Analysis of Variance (ANOVA). The mortalities of the extracts were observed to increase with increase in concentration and time of exposure. Larval mortality recorded at 72 hrs of exposure to 1000ppm of O gratissimum and T. catappa were 46.7% and 13.3% respectively. LC50 and LC90 values at 72 hrs were 1017.70 and 1372.10ppm respectively for O. gratissimum and 4043.60 and 15678.10ppm for T. catappa. While only steroids were identified as the phytochemicals present in T. catappa, those identified in O. gratissimum include alkaloids, flavonoids, saponins, steroids and tannins. The efficacy of both study plant extracts showed promising larvicidal potency. This is useful considering the current drive on Integrated Vector Management in controlling mosquito vector species on many fronts.

Published: June 2022

The objective of this study is to evaluate the cytogenetic consequences of exposing root tips of Allium cepa (onion) to varying distances and durations of radiation from the projector and treatment with sodium azide and distilled water using standard methods. The sodium azide and distilled water served as positive and negative controls respectively. Results obtained in this study revealed that radiations from the projector induced eleven chromosomal aberrations which included; binucleate cells, sticky chromosomes, vacuolated cells, star metaphase, bride chromosome, vagrant chromosome, faculty polarity, C-mitosis, spindle fibre disturbance, ghost cells, and fragmented chromosomes. This suggests that radiation from the projector poses danger to genetic systems. The higher mitotic index of irradiated onion root tip cells compared to negative control groups indicates that radiation from the projector exhibited a promontory effect on cell division. The findings in this study revealed that exposing cells to radiation beyond 20cm from projector reduced its potencies to induce aberrations as well as distortion of mitotic cell division cycles irrespective of the duration of exposure. This suggests that the genotoxic effects of radiations from a projector depend more on distance than the duration of exposure.
Toxicological Implication of Zinc Oxide Nano-Particles on Nutritional Composition and Depuration Potential of Heterobranchus longifilislis
Authors: Abdulkareem S. I. , Owolabi O. D.
Published: June 2022

Zinc Oxide nano-particles (ZnO-NPs) are more useful in the production of commercial goods than other nano-particles because of their unique properties. The effluents of ZnO-NPs get into the aquatic ecosystems and accumulate in fish tissues causing serious health consequences. This study was therefore designed to investigate the effect of ZnO-NPs exposure on the nutritional composition and depuration potential of large African catfish (Heterobranchus longifilis). The nutritional composition evaluated include, proximate composition, mineral content, fatty acids and amino acids profiles after exposing to varying (0.0, 6.00, 8.00, 10.00, 12.00 mg/l) concentrations of ZnO-NPs to juveniles’ catfish (H. longifilis) for 60 days and depurating for 30 days to evaluate recovery using standard methods. The results revealed that proximate composition and amino acid profiles decreased significantly (P < 0.05) after 60 days of exposure to ZnO-NPs, but gradually improved after 30 days of depuration. This implies that ZnO-NPs has a great influence on the nutrient values of H. longifilis, but the fish were able to regain the lost nutrients, however, the ability of H. longifilis to recover from adverse condition is time dependent.

Published: June 2022

The release of industrial wastewaters into the environment is a major source of toxic contaminants causing global health and environmental challenges. This study aimed to investigate the impact of electromagnetic field (EMF) treatment on bacterial population and physicochemical characteristics of cassava wastewater. Cassava wastewater sample was collected from point source of a small-scale cassava industry in Akure, Nigeria. Sample was thereafter treated with EMF of varying intensities (70- 130nT) and bacterial population and physicochemical properties of raw and treated wastewater sample were determined using standard microbiological, physical and chemical analytical techniques. Results revealed a total bacterial count of 1.34 x 105cfu/ ml. Identity of bacterial genera isolated from wastewater were Enterobacter aerogenes, Escherichia coli, Pseudomonas aeruginosa and Salmonella typhi (Gram negative) while the Gram positive bacteria were Staphylococcus aureus, Bacillus cereus, Bacillus subtilis and Lactobacillus sp. Results also revealed that treatment of wastewater sample with EMF significantly reduced the bacterial load and physicochemical parameters of the sample and dependent on EMF intensity and duration of exposure. Results revealed a decline in bacterial population from 1.34 x 105- 1.0 x 104 at intensities of 70nT-130nT and exposure time of 0- 144hr with the lowest count obtained at 130nT and the highest at 70nT. This study concludes that the use of Electromagnetic Field holds promise as an effective, non-invasive and eco-friendly strategy to improve the physical, chemical and biological quality of wastewater before discharge into the environment.

Anti-corruption law – a branch of Russian law and an academic discipline
Authors: Силкин В.П.
Published: June 2022

В статье анализируется вопрос, является ли антикоррупционное право самостоятельной отраслью российского права. Отмечается, что в соответствии с антикоррупционной политикой государства и с учетом активного нормотворчества в данной сфере во многих отечественных высших учебных заведениях преподаются учебные дисциплины, направленные на изучение в том или ином аспекте антикоррупционного законодательства и правоприменительной практики, однако единство по данным вопросам отсутствует. Анализируются основания для выделения отраслей российского права. Приводятся доводы о том, что признание существования антикоррупционного права в качестве самостоятельной отрасли может способствовать решению многих проблем, возникающих в процессе антикоррупционного нормотворчества, повышению качества антикоррупционного просвещения и популяризации в обществе антикоррупционных стандартов. На основании проведенного исследования сделан вывод о том, что антикоррупционное право – это самостоятельная комплексная отрасль российского права, регулирующая общественные отношения, возникающие в сфере противодействия коррупции

The article analyzes the question of whether anti-corruption law is an independent branch of Russian law. It is noted that in accordance with the anticorruption policy of the state and with regard to active rule-making in this area, many domestic higher educational institutions conduct academic disciplines aimed at studying anti-corruption legislation and law enforcement practice in one aspect or another, but there is no unity on these issues. The reasons for singling out branches of Russian law are analyzed. It is proved that recognition of the existence of anticorruption law as an independent branch of law can contribute to solving many problems arising in the process of anti-corruption rule-making, improving the quality of anti-corruption education and popularization of anti-corruption standards in society. Based on the conducted research, it is concluded that anti-corruption law is an independent complex branch of Russian law regulating public relations arising on anti-corruption issues
The binding mode of pyrazolone derived copper(II), cobalt(II), nickel(II) and zinc(II) Schiff base coordination compounds with Calf-Thymus DNA
Authors: Paulpandiyan R  , Raman N
Published: June 2022

Transition metal complexes with Schiff base ligands possess remarkable biomedical activities that could be used to develop new metal-based anticancer agents. Anticancer metal complexes have attracted considerable interest since the successful application of platinum based anti-cancer drugs. Pyrazolone derivatives have been extensively studied and have shown a wide range of pharmacological activities and anticancer activities. A new class of mononuclear copper (II), cobalt(II), nickel(II) and zinc(II) complexes were synthesized using pyrazolone precursor Schiff base, obtained by the condensation of 4–aminoantipyrine with salicylaldehyde and respective metal(II) chloride. They have been characterized by elemental analysis, magnetic susceptibility, molar conductance measurements, UV-Vis., FT-IR, 1H NMR spectra and EPR studies. Their magnetic susceptibility values of the complexes at room temperature are consistent with octahedral geometry around the central metal ions. These complexes show lower conductance values, supporting their non-electrolytic nature. The data show that the complexes have composition of [ML2] type. In vitro DNA binding profiles of all complexes have been explored by absorption titrations, cyclic voltammetry technique and viscosity measurements. The corroborative results of above experiments suggest that these complexes are efficient metallo intercalators and can interact with CT-DNA. The binding constant values (Kb) clearly signify that the complexes bind to DNA through intercalation mode. The binding affinity of these complexes with CT DNA is found to be in the order, Cu(II)>Zn(II)>Co(II)>Ni(II), among them copper complex  displaying a higher binding propensity as compared to other complexes.
Future of Teaching and Learning in the Post-Pandemic World
Authors: David Solomon Arulraj
Published: June 2022

This paper explores the top ten issues and ideas for the future of teaching and learning in the post-pandemic world. The study uses the researcher's informed reflection as a method. The informed reflector role allows the researcher to explore realities from multiple dimensions by scanning existing teaching and learning scholarship. The subjective accounting, the lack of external verification of the thinking, overshadows limitations. The researcher devises phenomenological bracketing to reduce the researcher to a reflector. The researcher acknowledges that there could be other critical issues and ideas than those in this study. Nevertheless, the reflections shared in this study may contribute to the existing stock of all other contemplations, discussions, and debates
POSTMODERN INTERCULTURAL COMMUNICATION: BEYOND NATIONAL AND ETHNIC IDENTITIES
Authors: Chastagner Claude
Published: June 2022

New modes of communication gradually emerged at the end of the 20th century, shifting the focus of attention from national and ethnic criteria to the more complex and multifarious ones suggested by the intercultural paradigm. This shift parallels the global tendency to move away from univocal, modernist perspectives to the more complex, and ambiguous postmodern ones. Downplaying the role of fixed national or ethnic identities in the communication process, and refusing simplifications and generalizations to emphasize instead fluidity and complexity, this new paradigm has had consequences on the lives of sub-groups and minorities, and on the communication process as a whole.

Authors: Harutyunyan Narine
Published: June 2022

The article is devoted to the analysis of new words and phrases that come to dominate global discourse and have made their way into language as a result of the pandemic. The aim of the study is to determine the impact of the COVID-19 pandemic on the formation of a special layer of the «coronavirus» language of the current moment, the appearance of neologisms included in the event context. The novelty of the research lies in the fact that the analysis of the pandemic realities is carried out by taking into account the famous typology of cultural dimensions developed by Geert Hofstede. The article also deals with extralinguistic conditions for creating new lexical units and examines the impact of the COVID-19 outbreak on linguistic reality. It also highlights the cultural characteristics of the perception of certain peoples of the new reality, notes the differences in response to changes and prohibitions during the ongoing pandemic. The main research methods are the descriptive method, the comparative method, the analysis of lexical definitions. The sources were articles on Internet sites, WhatsApp, the social network Instagram, Tweeter. Each period of serious breakdown leads to a change in the vocabulary and socio-cultural realities.

Published: June 2022

The conflict between the Muslim-Thai community and the Royal Thai Government for quite a long time since the acquisition of Southern Thailand Muslim areas (Yala, Narathiwat, Pattani, Songkhla and Satun) from Britain into the Thai kingdom under the umbrella of the Anglo-Siamese Treaty 1909. This historical research intends to answer one question: why did the Muslim-Thai conflict with the Royal Thai Government drag on? As a result, the Thai Government's initial program was to build nationalism with a Buddhist state ideology through the use of the Thai language with the Thai Rathaniyom jargon, which means Thailand for the Thai people. Malay language is prohibited, Islamic educational institutions must follow national education standards. This is where the Muslim-Thai resistance begins. The resistance varied to voice the aspirations of Muslim-Thai residents in the South who wanted them to be given the authority to manage themselves.

Estrategias de autoficción fabuladora en La muerte me da, de Cristina Rivera Garza
Authors: Admin Admin
Published: June 2022

En este artículo se aborda la cuestión de la autoficción fantástica o autofabuladora, teniendo como eje su especificidad que la lleva a establecer un pacto de lectura ambiguo que impide la confusión entre el autor y su personaje, imposibilitando que se realice una lectura en clave autobiográfica de estas autoficciones. Esta reflexión se plantea realizando un acercamiento a la obra La muerte me da, de la mexicana Cristina Rivera Garza. El objetivo es ejemplificar las estrategias narrativas de que se sirve esta forma autoficcional para construir su ambigüedad. En esta obra específica, podemos identificar que dichas estrategias se presentan en dos grupos: la combinación de referencialidad y ficción, y la adscripción al género policiaco.
Synthesis and evaluation of Niobium or Vanadium – doped heteropolyacid catalysts in oxidation and acetalization reactions of alcohols and aldehydes derivated of biomass
Authors:   , Vergara Torres John Alexander
Published: June 2022

Aldehydes derived from biomass and terpene alcohols are abundant raw materials, of plant origin, and of interest for production of fine chemicals products, such as fragrances, pharmaceuticals and agrochemicals. Recently, for economic and environmental reasons, catalytic processes have been developed to transform these renewable resources into chemical products with higher added value. In this work, heteropolyacids (HAPs) obtained from phosphomolybdic acid doped with 1, 2, and 3 mol of Niobium (i.e., H 4 PMo 11 Nb 1 O 40 , H 5 PMo 10 Nb 2 O 40 and H 6 PMo 9 Nb 3 O 40 ) were synthesized and evaluated as catalysts in oxidation and acetalization reactions of aldehydes present in the biomass. Niobium- doped HAPs were synthesized from different precursors: MoO 3 , Nb 2 O 5 , H 3 PO 4. Furthermore, HAPs obtained from the doping of phosphomolybdic acid with Vanadium were applied in oxidation reactions of terpene alcohols by hydrogen peroxide in acetonitrile solutions. The synthesis procedures used proved to be efficient, since the catalyst were obtained with satisfactory yields. All synthesized acids were characterized by infrared spectroscopy analysis, ultraviolet-visible spectroscopy, thermal analysis, surface area and porosimetry, X-ray diffraction, and potentiometric titration. The catalytic activity of HAPs was evaluated in different oxidation and acetalization reactions. The Nb-doped HAPs were evaluated in oxidative esterification reaction of furfural, chosen as a model substrate due to its reactivity and industrial interest. In addition, they were also evaluated in acetalization reaction. In this reaction, the amount of Nb does not seem to have produced a significant difference in terms of conversion and selectivity. Furthermore, most of the catalytic tests were performed with H 6 PMo 9 Nb 3 O 40 obtaining conversion of approximately 50% and 2-furfuraldehyde-methylacetal as the only product. The concentration of 0.0312 mol % of catalyst presents the best catalytic activity. Finally, the reaction was extended to benzaldehyde, obtaining similar results. Tests performed with Vanadium-doped catalysts showed that H 4 PMo 11 VO 40 was the most active and selective in the oxidation of geraniol (the substrate chosen as model terpene alcohol) toward geraldehyde, mono and diepoxide, with epoxide being the major product. Conversion greater than 94% was obtained with selectivity between 80 and 85% for epoxide geraniol. H 4 PMo 11 VO 40 has also been tested in the oxidation of other terpene alcohols, and has been shown to be active in the oxidation of nerol. Keywords: Furfural. Terpene alcohols.

The present study covers a part of the trematode diversity in a variety of ducks migratory birds mainly including pochards found in the water bodies of Sindh, Pakistan. In the present study, the birds were collected from different water bodies using the mist nest with the help of local bird catchers. Birds were dissected for their helminthes. The treaded parasites were processed for permanent mounting in Canada balsam and for further microscopic examination. In total, 70 birds belonging to three species of pochards of Genus Aythya (Anatidae: Anseriformes), A. ferina, A. fuligula and A. nyroca were collected from different water bodies during 2019-2020. The results showed five species of digenean trematodes including Psilochasmus singhi Jaiswal and Humayun, 1971, Psilochasmus oxyurus (Creplin, 1825), Catatropis pakistanensis Shafi et al., 1982, Echinochasmus amphibolus Kotlan, 1922 and Notocotylus attenutus (Rudolphi, 1809). All species were identified on the basis of their generic and specific characters including, body shape and size, position of oral sucker, cirrus pouch, genital pore, cecca, number of uterine loops, shape position of testes and ovaries. This is the first parasitological study on trematodes infecting the genus Aythya from Sindh, Pakistan.

Concrete is most suitable construction material. And it will adapt very well with the situations in the site. This concrete is considered as a homogeneous material but it is mixture of cement and fine aggregate and coarse aggregate and water. There are various methods in-order for concrete to gain strength, replacing the contents of concrete is also a way but partially is considered optimum. Now main binding agent in the concrete is the cement content so by partially replacing the cement by various cementitious materials like GGBS and tio2 will give optimum results in raised strength values of concrete. In this study a small trial is done to modify the properties of concrete by partial replacement of cement with GGBS of a percentage 10%, 20%, 30% and 40% and TIO2 of percentages of 0.6%, 0.8%, 1.0% and 1.25%. Different tests are done to determine Compressive Strength and split tensile strength All the cubes are used for 7 & 28 days.
