Published: August 2020

The present research is conducted on the Chinese corporate sector and raises the basic questions associated with the adoption and implementation of corporate disclosure practices such as SDGs. The sample for this research consisted of 100 Chinese companies, which are listed in the Shanghai Stock Exchange from 2016 to 2018. For this purpose, content analysis is developed. More specifically, a quantitative approach is applied to quantify and identify certain contents or words in the given text. Our results show that Chinese companies seem to be more focused on certain aspects of the UN SDGs at the cost of others, but the overall situation is, at best, not encouraging. The focus of attention of Chinese companies seems to be infrastructure development, industrial innovation, and economic growth, along with the provision of a dignified and respectable working environment, affordable and clean energy, and peace, justice, and strong institutions. The results can be used as guidelines by Chinese companies to determine the actual presence or absence of SDGs implementation inside the process of value creation as an integral part of their practices about corporate disclosure. The main contribution of this research relates to the analysis of the adoption and implementation efforts to report SDGs and the contribution of such reporting towards the fulfillment of the UN Agenda 2030. This can be of interest to researchers working on the given topic. It is of utmost importance for government policymakers and corporate decision-makers, who want to support companies that are contributing towards the achievement and adaptation of SDGs as part of their overall objectives.

Authors: Byrne Joshua , Mouritz Mike , Taylor Mark , Breadsell Jessica K.
Published: August 2020

With increasing pressure to ensure that sustainability features in homes are commercially viable, demonstration projects are vital to highlight the real-world challenges and opportunities for innovation. This paper documents the incorporation of sustainability objectives into the “East Village at Knutsford” residential “living laboratory” development, within the Knutsford urban regeneration precinct, approximately 1.5 km east of the Fremantle central business district in Western Australia. The sustainability objectives for the project include being a “Net Zero Energy Development” using 100% renewable energy and maximizing the self-supply of energy, reducing mains water consumption as much as is practical, and using the landscape design to complement these objectives without compromising a best-practice urban greening outcome. The paper documents the design initiatives and strategies that have been included to achieve these objectives in a commercially viable project and the results of modelling where it has been used to test the design against the objectives to ensure their validity. The key features that have been incorporated into the townhouses component of the development are outlined, illustrating integrated design and systems thinking that builds on previous demonstration projects, incorporating solar energy storage and electric vehicle charging plus significant mains water savings by adopting water-sensitive features in the homes and the within the private and public gardens. The expected grid energy and mains water consumption levels in the homes through modelling compared to the metropolitan average is 80% lower. The project is presented as an important step in the application of available technologies and design features to meet stated sustainability objectives, highlighting the benefits of an embedded living laboratory research approach.
Youth Engagement in Climate Change Action: Case Study on Indigenous Youth at COP24
Authors: MacKay Makenzie , Parlee Brenda , Karsgaard Carrie
Published: August 2020

While there are many studies about the environmental impacts of climate change in the Canadian north, the role of Indigenous youth in climate governance has been a lesser focus of inquiry. A popularized assumption in some literature is that youth have little to contribute to discussions on climate change and other aspects of land and resource management; such downplay of youth expertise and engagement may be contributing to climate anxiety (e.g., feelings of hopelessness), particularly in remote communities. Creating opportunities for youth to have a voice in global forums such as the United Nations Conference of Parties (COP24) on Climate Change may offset such anxiety. Building on previous research related to climate action, and the well-being of Indigenous youth, this paper shares the outcomes of research with Indigenous youth (along with family and teachers) from the Mackenzie River Basin who attended COP24 to determine the value of their experience. Key questions guiding these interviews included: How did youth impact others? and How did youth benefit from the experience? Key insights related to the value of a global experience; multiple youth presentations at COP24 were heard by hundreds of people who sought to learn more from youth about their experience of climate change. Additional insights were gathered about the importance of family and community (i.e., webs of support); social networks were seen as key to the success of youth who participated in the event and contributed to youth learning and leadership development.
Does Voting Solve the Intergenerational Sustainability Dilemma?
Authors: Katsuki Shun , Hizen Yoichi
Published: August 2020

Does voting solve the intergenerational sustainability dilemma? Do voting rules matter when trying to induce people to collectively select a sustainable alternative that leaves more resources for future generations? To answer these questions, we conducted a laboratory experiment using an intergenerational sustainability dilemma game in which players are asked to choose between two alternatives. Choosing the alternative that maximizes the players’ immediate benefit decreases the resources left for subsequent generations. The choice is made by the votes cast within small groups representing successive generations. We compare three voting rules: ordinary voting, whereby each person in the group has one vote; proxy voting, whereby some but not all of the players are given an extra vote to cast on behalf of subsequent generations; and two-ballot voting, whereby all players are given an extra vote. We observe that both proxy voting and two-ballot voting increase the frequency at which the sustainable alternative is selected; however, the frequency of such a choice remains low. This suggests that voting individually is a relatively ineffective way to elicit sustainable choices from successive generations even if the rules of voting are modified.
Hyper-Heuristic Framework for Sequential Semi-Supervised Classification Based on Core Clustering
Authors: Adnan Ahmed , Muhammed Abdullah , Abd Ghani Abdul Azim , Abdullah Azizol , Hakim Fahrul
Published: August 2020

Existing stream data learning models with limited labeling have many limitations, most importantly, algorithms that suffer from a limited capability to adapt to the evolving nature of data, which is called concept drift. Hence, the algorithm must overcome the problem of dynamic update in the internal parameters or countering the concept drift. However, using neural network-based semi-supervised stream data learning is not adequate due to the need for capturing quickly the changes in the distribution and characteristics of various classes of the data whilst avoiding the effect of the outdated stored knowledge in neural networks (NN). This article presents a prominent framework that integrates each of the NN, a meta-heuristic based on evolutionary genetic algorithm (GA) and a core online-offline clustering (Core). The framework trains the NN on previously labeled data and its knowledge is used to calculate the error of the core online-offline clustering block. The genetic optimization is responsible for selecting the best parameters of the core model to minimize the error. This integration aims to handle the concept drift. We designated this model as hyper-heuristic framework for semi-supervised classification or HH-F. Experimental results of the application of HH-F on real datasets prove the superiority of the proposed framework over the existing state-of-the art approaches used in the literature for sequential classification data with evolving nature.
Neutrino Oscillations in the Presence of Matter and Continuous Non-Selective Measurement
Authors: Khan Fazeel , Dajka Jerzy
Published: August 2020

We investigate three-flavor neutrino oscillation affected by an environment mimicking a continuous non-selective measurement. We show that such a coupling that is given by a measured observable affects probability of inter-flavor neutrino transition and a steady-state correlation function of the neutrino’s flavor. We juxtapose and compare our predictions influenced by matter’s scattering and CP-violation.
A Digital Twin-Based Approach for the Fault Diagnosis and Health Monitoring of a Complex Satellite System
Authors: Shangguan Duansen , Chen Liping , Ding Jianwan
Published: August 2020

The ever-increasing functional density and complexity of the satellite systems, the harsh space flight environment, as well as the cost reduction measures that require less operator involvement are increasingly driving the need to develop new approaches for fault diagnosis and health monitoring (FD-HM). The data-driven FD-HM approaches use signal processing or data mining to obtain implicit information for the operating state of the system, which is good at monitoring systems extensively and shallowly and is expected to reduce the workload of the operators. However, these approaches for the FD-HM of the satellite system are driven primarily by the historical data and some static physical data, with little consideration for the simulation data, real-time data, and data fusion between the two, so it is not fully competent for the real-time monitoring and maintenance of the satellite in orbit. To ensure the reliable operation of the complex satellite systems, this paper presents a new physical–virtual convergence approach, digital twin, for FD-HM. Moreover, we present an FD-HM application of the satellite power system to demonstrate the effectiveness of the proposed approach.
Clinical Implications of Difference in Antigenicity of Different Botulinum Neurotoxin Type A Preparations: Clinical Take-Home Messages from Our Research Pool and Literature

Published: August 2020

The three different botulinum toxin type A (BoNT/A) preparations being licensed in Europe and the U.S. differ in protein content, which seems to be a major factor influencing the antigenicity of BoNT/A. In the present study, several arguments out of our research pool were collected to demonstrate that the clinical response and antigenicity were different for the three BoNT/A preparations: some results of (1) a cross-sectional study on clinical outcome and antibody formation of 212 patients with cervical dystonia (CD) being treated between 2 and 22 years; (2) another cross-sectional study on the clinical aspects and neutralizing antibody (NAB) induction of 63 patients having developed partial secondary treatment under abobotulinum (aboBoNT/A) onabotulinumtoxin (onaBoNT/A) who were switched to incobotulinumtoxin (incoBoNT/A) in comparison to 32 patients being exclusively treated with incoBoNT/A. These results imply that (1) the presence of NAB cannot be concluded from the course of treatment, that (2) an increase in the dose and variability of outcome with treatment duration indicates the ongoing induction of NABs over time, that (3) the higher protein load of BoNT/A goes along with a higher incidence and prevalence of NAB induction and that (4) the best response to a BoNT/A is also dependent on the protein load of the preparation.

Published: August 2020

In contrast to comprehensively investigated antibacterial activity of snake venoms, namely crude venoms and their selected components, little is known about antifungal properties of elapid snake venoms. In the present study, the proteome of two venoms of red spitting cobra Naja pallida (NPV) and Mozambique spitting cobra Naja mossambica (NMV) was characterized using LC-MS/MS approach, and the antifungal activity of crude venoms against three Candida species was established. A complex response to venom treatment was revealed. NPV and NMV, when used at relatively high concentrations, decreased cell viability of C. albicans and C. tropicalis, affected cell cycle of C. albicans, inhibited C. tropicalis-based biofilm formation and promoted oxidative stress in C. albicans, C. glabrata and C. tropicalis cells. NPV and NMV also modulated ammonia pulses during colony development and aging in three Candida species. All these observations provide evidence that NPV and NMV may diminish selected pathogenic features of Candida species. However, NPV and NMV also promoted the secretion of extracellular phospholipases that may facilitate Candida pathogenicity and limit their usefulness as anti-candidal agents. In conclusion, antifungal activity of snake venoms should be studied with great caution and a plethora of pathogenic biomarkers should be considered in the future experiments.

Published: August 2020

Spider venoms represent an original source of novel compounds with therapeutic and agrochemical potential. Whereas most of the research efforts have focused on large mygalomorph spiders, araneomorph spiders are equally promising but require more sensitive and sophisticated approaches given their limited size and reduced venom yield. Belonging to the latter group, the genus Lycosa (“wolf spiders”) contains many species widely distributed throughout the world. These spiders are ambush predators that do not build webs but instead rely strongly on their venom for prey capture. Lycosa tarantula is one of the largest species of wolf spider, but its venom composition is unknown. Using a combination of RNA sequencing of the venom glands and venom proteomics, we provide the first overview of the peptides and proteins produced by this iconic Mediterranean spider. Beside the typical small disulfide rich neurotoxins, several families of proteins were also identified, including cysteine-rich secretory proteins (CRISP) and Hyaluronidases. Proteomic analysis of the electrically stimulated venom validated 30 of these transcriptomic sequences, including nine putative neurotoxins and eight venom proteins. Interestingly, LC-MS venom profiles of manual versus electric stimulation, as well as female versus male, showed some marked differences in mass distribution. Finally, we also present some preliminary data on the biological activity of L. tarantula crude venom.
On the Role of Einstein–Cartan Gravity in Fundamental Particle Physics
Authors: Diether III Carl F. , Christian Joy
Published: August 2020

Two of the major open questions in particle physics are: (1) Why do the elementary fermionic particles that are so far observed have such low mass-energy compared to the Planck energy scale? (2) What mechanical energy may be counterbalancing the divergent electrostatic and strong force energies of point-like charged fermions in the vicinity of the Planck scale? In this paper, using a hitherto unrecognised mechanism derived from the non-linear amelioration of the Dirac equation known as the Hehl–Datta equation within the Einstein–Cartan–Sciama–Kibble (ECSK) extension of general relativity, we present detailed numerical estimates suggesting that the mechanical energy arising from the gravitationally coupled self-interaction in the ECSK theory can address both of these questions in tandem.
Removing the Polyanionic Cargo Requirement for Assembly of Alphavirus Core-Like Particles to Make an Empty Alphavirus Core
Authors: Button Julie M. , Mukhopadhyay Suchetana
Published: August 2020

The assembly of alphavirus nucleocapsid cores requires electrostatic interactions between the positively charged N-terminus of the capsid protein (CP) and the encapsidated polyanionic cargo. This system differs from many other viruses that can self-assemble particles in the absence of cargo, or form “empty” particles. We hypothesized that the introduction of a mutant, anionic CP could replace the need for charged cargo during assembly. In this work, we produced a CP mutant, Minus 38 (M38), where all N-terminal charged residues are negatively-charged. When wild-type (WT) and M38 CPs were mixed, they assembled into core-like particles (CLPs). These “empty” particles were of similar size and morphology to WT CLPs assembled with DNA cargo, but did not contain nucleic acid. When DNA cargo was added to the assembly mixture, the amount of M38 CP that was assembled into CLPs decreased, but was not fully excluded from the CLPs, suggesting that M38 competes with DNA to interact with WT CPs. The composition of CLPs can be tuned by altering the order of addition of M38 CP, WT CP, and DNA cargo. The ability to produce alphavirus CLPs that contain a range of amounts of encapsidated cargo, including none, introduces a new platform for packaging cargo for delivery or imaging purposes.

Chikungunya virus (CHIKV) was first reported in Brazil in 2014 and, after it spread countrywide, an outbreak of febrile illness with reports of arthralgia happened in the municipality of Xinguara, Pará, Brazil in 2017, indicating the virus’ circulation. Here, we aimed to investigate CHIKV in mosquito vectors collected during an active surveillance of virus isolation in cell culture by using molecular detection and viral genome sequencing. A total of 492 Aedes, Culex and Mansonia mosquitoes were collected and separated in 36 pools according to the species and sex, and 22.2% (8/36) were positive. CHIKV was indentified in pools of Ae. aegypti females (n = 5), an Ae. aegypti male (n = 1) and in Culex quinquefasciatus females (n = 2). However, as the mosquitoes’ whole bodies were macerated and used for detection, one cannot suggest the role of the latter in the viral transmission. Despite this, vector competence studies must be carried out in the different species to investigate long-term adaptations. Viral genome sequencing has characterized the East-Central-South-African (ECSA) genotype in all positive pools analyzed, corroborating previous reports for the Amazon region.

Innate responses provide the first line of defense against viral infections, including the influenza virus at mucosal surfaces. Communication and interaction between different host cells at the early stage of viral infections determine the quality and magnitude of immune responses against the invading virus. The release of membrane-encapsulated extracellular vesicles (EVs), from host cells, is defined as a refined system of cell-to-cell communication. EVs contain a diverse array of biomolecules, including microRNAs (miRNAs). We hypothesized that the activation of the tracheal cells with different stimuli impacts the cellular and EV miRNA profiles. Chicken tracheal rings were stimulated with polyI:C and LPS from Escherichia coli 026:B6 or infected with low pathogenic avian influenza virus H4N6. Subsequently, miRNAs were isolated from chicken tracheal cells or from EVs released from chicken tracheal cells. Differentially expressed (DE) miRNAs were identified in treated groups when compared to the control group. Our results demonstrated that there were 67 up-regulated miRNAs, 157 down-regulated miRNAs across all cellular and EV samples. In the next step, several genes or pathways targeted by DE miRNAs were predicted. Overall, this study presented a global miRNA expression profile in chicken tracheas in response to avian influenza viruses (AIV) and toll-like receptor (TLR) ligands. The results presented predicted the possible roles of some DE miRNAs in the induction of antiviral responses. The DE candidate miRNAs, including miR-146a, miR-146b, miR-205a, miR-205b and miR-449, can be investigated further for functional validation studies and to be used as novel prophylactic and therapeutic targets in tailoring or enhancing antiviral responses against AIV.
Interaction Analysis of Urban Blue-Green Space and Built-Up Area Based on Coupling Model—A Case Study of Wuhan Central City
Authors: Wu Jing , Yang Shen , Zhang Xu
Published: August 2020

Urban “blue-green” space is the basic element of urban natural ecological space. The rapid urbanization process has a significant impact on the pattern of urban blue-green space and seriously threatens the urban ecological environment. It is of great significance for urban ecological protection and sustainable development to study the change in characteristics of blue and green space during urban expansion. In this paper, a comprehensive method of remote sensing image, landscape pattern analysis, sector analysis, and coupling analysis is applied to analyze the spatio-temporal evolution characteristics and coordinated development level of the blue-green space and built-up area in central Wuhan from 1987 to 2018. The results showed that the land use and landscape pattern in the central city of Wuhan underwent a drastic change process, and the dominant change was the occupation of blue-green space by urban built-up areas, which led to the increase of landscape fragmentation and the decrease of heterogeneity. Urban green space is gradually marginalized and concentrated in local areas. The blue space has an obvious blocking effect on the expansion of the built-up area, and its spatial pattern tends to be stable gradually. In addition, the coupling degree between urban blue-green space and urban built area presents an inverted U-shape, and the coordinated development level among the three has entered a stage of moderate imbalance. It is urgent to strengthen the protection of blue-green space, curb the disorderly expansion of cities, and improve the quality of urban development.

Waterborne diseases are a global problem that causes more than 2.2 million deaths annually. Therefore, the present study was focused on microbiological contamination of both ground and surface water by means of total coliform, Escherichia coli (E. coli), Salmonella spp., Shigella spp. and Campylobacter spp. Seventy two groundwater and 45 surface water sampling locations were selected to collect water from the head, transitional and meandering regions of the Kelani River Basin for a period of one year (both dry and wet seasons). The results of the study revealed that the entire Kelani River basin was contaminated with total coliform and E. coli bacteria and almost all the sampling locations exceed Sri Lanka Standards Institute (SLSI) guideline value given for drinking water (0 CFU/100 mL). Further, in groundwater, 17 locations were positive for Salmonella spp., whereas only 2 locations were positive for Campylobacter spp. In surface water, 26 and three sampling locations were positive for Salmonella spp. and Campylobacter spp., respectively. In this study, 23 different human pathogenic serovars were isolated and the Salmonella enterica serovar Kentucky was identified as the commonest type. Thus, the result of the study revealed that the consumption of raw water from the Kelani River Basin is unsafe and possible to cause gastrointestinal diseases.

The bleak Alburnus alburnus is native to most of Europe. This cyprinid fish is a successful invader in the Iberian Peninsula. No studies exist on its foraging strategies on a large scale for this ecoregion. The aim of the present study was to compare dietary traits of invasive bleak among the main Iberian rivers and a ‘reference’ native bleak population from France. Bleak were sampled during May–June 2019 from the Iberian Rivers Ebro, Tagus, Guadiana, Segura and Guadalquivir and the River Saône (France). Diptera larvae and zooplankton were common food categories in the River Saône. Insect nymphs were more important in the River Ebro. The intake of plant material was higher in the River Tagus. Flying insects were more consumed in the River Guadiana. Nektonic insects were important in the River Guadalquivir. Detritus was a frequent food category for all populations, in terms of occurrence and mass. Dietary parameters followed a unimodal response in relation to the latitudinal gradient, with the maximum values for the Tagus and Guadiana populations. Overall, results suggest that this wide interpopulation variability will contribute to the species’ successful establishment throughout Mediterranean Europe, which poses a serious risk to its highly valuable native fish fauna.

O cloreto de potássio é um adubo salino que pode prejudicar o cultivo se for utilizado de forma incorreta nas lavouras. Atualmente vários programas de fertilização recomendam elevadas adubações potássicas para o cultivo da soja, porém deve ser levado em consideração alguns critérios para a sua recomendação, a exemplo da profundidade de semeadura e a dosagem da adubação. Com o objetivo de avaliar o efeito da salinidade do cloreto de potássio em plântulas de soja foi instalado um experimento fatorial 3x3 com três níveis de profundidade de semeadura (0, 3 e 6) e três doses de KCl (0,208 g., 0,346g. e 0,485 g.Kg-1 de solo), foram avaliados as seguintes características: emergência, massa seca da parte aérea, massa seca das raízes, altura de plântulas e comprimento de raízes. Em todas as variáveis houve efeito para profundidade de semeadura, sendo que na profundidade 0 (contato da semente com adubo) houve redução da emergência e decréscimo no vigor de todas as características avaliadas.

В статье приводятся результаты исследований полиморфизма генов кальпаина (CAPN1) и гормона роста (GH) и их влияние на динамику живой массы и показатели мясной продуктивности молодняка крупного рогатого скота казахской белоголовой породы. Генотипирование по гену CAPN1 проводилось методом ПЦР-РВ с использованием аллель-специфичных зондов; по гену GH — ПЦР-ПДРФ. Установлено, что частоты встречаемости желательных аллелей С и V, соответственно, в CAPN1 и GH составили 0,40 и 0,12, гомозиготных генотипов — 0,31 и 0,6. Носители генотипов СС и VVв генах CAPN1 и GH имели большую живую массу в возрасте 8 мес на 13,8 и 6,9% и 12 мес на 14,6 и 6,9% по сравнению с GG и LL генотипами. Наибольшие предубойная, убойная масса и масса туши отмечались для туш, полученных от гомозиготных CC и VV бычков в генах CAPN1 и GH. Их превосходство над GG и LL генотипами составило, соответственно, 19,3; 16,2 и 16,4 кг; 19,8; 19,1 и 16,1 кг. Гомозиготные бычки имели лучшие показатели по коэффициенту мясности на 4,1 и 2,0% и убойному выходу — на 1,4 и 2,0%. Содержание белка и жира в длиннейшей мышце спины туш бычков СС и VV-генотипов было выше на 0,28—2,13%. Полученные данные свидетельствуют о перспективности отбора животных, в генотипе которых присутствуют желательные аллели и подбора родительских пар для получения большего числа потомков с гомозиготным генотипом.

The results of the investigation on polymorphism of calpain (CAPN1) and growth hormone (GH) genes are presented, and also their influence on live weight dynamics and other traits of meat productivity in Kazakh white-headed young bulls. Genotyping of CAPN1 gene was performed by PCR-RT method using allele-specific probes, GH gene — PCR-RFLP. It was found that frequencies of desired alleles C and V in CAPN1 and GH respectively were 0.40 and 0.12, homozygous genotypes - 0.31 and 0.60. It was determined that CC (CAPN1 gene) and VV (GH gene) genotypes had higher live weight, than GG and LL genotypes. Their exceedance was 13.8 and 6.9% respectively for 8-month age and 14.6 and 6.9% for 12-month age. The highest pre-slaughter, slaughter weight and carcass weight were observed for homozygous CC and VV bulls for CAPN1 and GH genes. Their significant difference over GG and LL genotypes was 19.3, 16.2 and 16.4 kg, 19.8, 19.1 and 16.1 kg respectively. Homozygous CC and VV bulls had average weight of meat, higher by 4.1 and 2.0 percent than bull with other genotypes; and their average slaughter yield was also higher 1.4 and 2.0 abs. percent. Protein and fat content in longissimus dorsi of CC and VV genotypes was 0.28—2.13 abs. higher. The data obtained indicate that selection of the animals whose genotypes contain desirable alleles and matching of parents will increase the frequency of homozygous genotype.
X-RAY SPECTRAL MICROANALYSIS OF ELECTROEROSIVE POWDER MATERIAL OBTAINED IN AN ETHYL ALCOHOL MEDIUM FROM WASTE OF A NON-TUNGSTEN HARD ALLOY OF THE KNT16 BRAND
Authors: Ageeva E. V. , Sabel’nikov B. N.
Published: August 2020

The first appearance of tungsten-free hard alloys (TFHA) was noted in the early 30s of the last century, but they did not receive due attention and, accordingly, spread due to insufficient strength and were replaced by tungsten-containing alloys of such groups as VK, TC and TTK. However, the rapidly developing shortage of expensive tungsten pushed in the late 50s to return to the search for hard alloys, the composition of which does not include tungsten. Due to the growing demand for tungsten-free hard alloys, the problem of recycling their waste with the possibility of reuse is acute in the industry. The purpose of this work was to conduct x-ray spectral microanalysis (RSMA) of powder material (PM) obtained by electroerosive dispersion (EED) in ethyl alcohol from waste of a non-tungsten hard alloy of the KNT16 brand. The resulting powder material was examined using an energy-dispersion x-ray analyzer from EDAX, built into a scanning electron microscope "QUANTA 600 FEG". In the course of scientific research, the spectra of characteristic x-ray radiation on the surface of the experimentally obtained sample were obtained. The results obtained in the course of scientific research can be used to create environmentally friendly resource-saving processes for processing waste of tungsten-free hard alloys into powder materials.

Published: August 2020

The paper describes in detail the application of the shadow method for physical modeling of the solidification process of large ingots, for visualizing and quantifying convective flows. As a result of the experiment, the proposed method allowed to visualize convective flows during casting and solidification of the model ingot. At the end of casting, the flows are represented as a vortex movement, as the further solidification of the flow changes to a more uniform appearance, they have a laminar appearance, while their visualization deteriorates. In the initial moments of time, the rate of descending flows is higher than the rate of ascending ones. Further, as the solidification continues, the rate of descending flows decreases, and the rate of ascending flows increases. The results obtained are in good agreement with the literature data, as well as with industrial experiments, which makes it possible to consider this method of studying the convective movement of a liquid in an ingot appropriate.

Enseñanza de la literatura, formación de lectores y discursos educacionales: El problema de las culturas populares en el cotidiano escolar

Published: August 2020

"Enseñanza de la literatura, formación de lectores y discursos educacionales: el problema de las culturas populares en el cotidiano escolar" indaga, en principio, las premisas constitutivas de las perspectivas dominantes sobre la enseñanza de la literatura y la formación de lectores privilegiando, en particular, sus usos y apropiaciones de una concepción eurocéntrica que opera negando o negativizando fenómenos del cotidiano escolar relativos a las culturas populares. Dichas perspectivas vienen incidiendo en las políticas públicas de la Argentina, al menos desde las últimas cuatro décadas, específicamente en los lineamientos, contenidos y propuestas didácticas para las áreas y niveles del sistema educativo nacional que son de su incumbencia, según las denominaciones asumidas por cada jurisdicción (Lengua, Literatura, Lengua y Literatura, Prácticas del Lenguaje) y en otras acciones como planes y programas de lectura. En los términos antes planteados, estas perspectivas son revisadas a través de situaciones concretas de trabajo docente, es decir de enseñanza de la literatura, mediante el recorte, principalmente, de intervenciones de los alumnos. Así, se estudian una serie de características específicas del cotidiano escolar respecto de la enseñanza de la literatura que nos permiten abordar problemas históricos, sociales, culturales, lingüísticos, estéticos y literarios, para explicarlos respecto de cómo han sido y son definidas las culturas populares en las ciencias sociales. Por último, mediante estas revisiones y los abordajes señalados se proponen reformulaciones de los problemas actuales de la enseñanza de la literatura fundados y validados en el propio trabajo docente.
Biodiversidad de artrópodos en ecosistemas agrícolas minifundistas de la provincia de Salta (Argentina) con énfasis en Araneae y Heteroptera depredadores
Authors:   , Olivo Verónica Inés
Published: August 2020

En esta tesis se consideró necesario analizar la diversidad de la artropodofauna y la dinámica de sus grupos funcionales en parcelas cultivadas de minifundios del Valle de Lerma, como un “todo”, a fin de conocer mejor su dinámica interna por cuanto ello nos permitirá planificar en el futuro, actividades tendientes a una producción agrícola sustentable en el tiempo. Para ello se plantearon los siguientes objetivos específicos: a-analizar la biodiversidad de artrópodos asociados a diferentes ecosistemas agrícolas minifundistas del Valle de Lerma) en términos de abundancia y riqueza de especies; b- determinar y comparar la diversidad de los ensamblajes de enemigos naturales, con énfasis en Araneae y Heteroptera depredadores, en minifundios con diferentes manejos y heterogeneidad ambiental (de monocultivos a policultivos) y en hábitats adyacentes diferentes en composición y estructura de la vegetación.
Invasión de Limnoperna fortunei (Dunker, 1857)
Authors:   , Pereyra Patricio Javier
Published: August 2020

El mejillón dorado, Limnoperna fortunei (Dunker, 1857) fue introducido en forma accidental en América del Sur, por el agua de lastre de buques transoceánicos, en los principios de la década del ´90. Se trata de una especie gonocórica, dulciacuícola, con fertilización externa, cuya larva veliger vive aproximadamente cuatro semanas en el plancton antes de fijarse a cualquier sustrato duro para convertirse en juvenil. La longevidad de esta especie es de aproximadamente tres años. Este bivalvo es considerado como una especie invasora en la cuenca del Plata. Posee características morfo-funcionales semejantes a las del mejillón cebra, Dreissena polymorpha (Pallas, 1771) en el Hemisferio Norte. Ambas especies, cada una en su área de distribución, impactan sobre el funcionamiento de los ecosistemas nativos y obstaculizan el funcionamiento de las plantas industriales que utilizan agua de río cruda en sus sistemas. En este trabajo de tesis se propone establecer las características poblacionales de L. fortunei en un ambiente humano invadido (Central Hidroeléctrica Yacyretá); evaluar distintos biocidas de origen orgánico para la prevención/control de L. fortunei; y estimar el impacto causado por esta especie sobre la fauna de bivalvos infaunales, en particular sobre Corbicula fluminea (Müller, 1774).
El potencial hermenéutico en Trabajo Social Contemporáneo: Aplicación de un filtro de análisis comprensivo a algunos textos disciplinarios
Authors:   , Yáñez Pereira Víctor Rodrigo
Published: August 2020

Entendiendo que Trabajo Social se traduce contemporáneo por sus matrices y enfoques, esta Tesis procura develar el potencial hermenéutico de la disciplina, tomando como foco de observación algunos de sus textos, pero, sin sujetamiento a latitudes geográficas específicas, sino más bien al constructo profesional en general. Para esto, se construyó un filtro de análisis comprensivo que, basado en contenidos manifiestos y temáticos, permitió descifrar el desarrollo de dicho potencial, a través de sus condiciones, características y requisitos; apuntando a las figuras hermenéuticas presentes en los textos de estudio, seleccionados como evidencia empírica dentro de un muestreo por conveniencia, en base a una metodología cualitativa. Los resultados dieron cuenta del lugar hermenéutico con que estos “documentos” ilustran proposiciones para situar opciones, cualidades y dimensiones de re-significación en torno a Trabajo Social, a saber: criticidades, deconstrucciones y reflexividades hermenéuticas, desde donde el autor de esta investigación proyecta principios de falta, falla y obstáculo para hacer emerger una hermenéutica vacía, que aporte a la formación, la intervención y la investigación disciplinar, con los límites iniciales que coloca la experiencia personal, profesional y académica del propio investigador.
Impactos del transporte sobre el paisaje urbano
Authors:   , Barbero Dante Andrés
Published: August 2020

En este trabajo se aborda la complejidad de un paisaje urbano desde un enfoque sistémico, a los efectos de analizar de manera integrada el conjunto de dimensiones que lo componen. Tal como lo señala el título de la tesis, se puso énfasis sobre los principales impactos del transporte automotor que actúan como agentes de degradación del paisaje. En particular, se analizaron dos aspectos relacionados con la contaminación: las emisiones producidas por el transporte automotor (vinculado con la contaminación atmosférica) y el nivel de ruido (relacionado con la contaminación sonora) en el área de estudio. Estos impactos fueron cuantificados y luego contrastados con la percepción de los habitantes a los efectos de observar si lo medido coincidía con lo percibido por los ciudadanos. A partir de los resultados obtenidos de la contrastación se sugirieron medidas, a partir de criterios de planificación del paisaje, para reducir los impactos negativos ocasionados por el transporte automotor y mejorar el estado del paisaje urbano analizado.
