Authors: Fathi Amirhossein , Bararzadeh Ledari Masoomeh , Saboohi Yadollah
Published: September 2021

The paper studies the optimum panel horizontal orientation angle toward the Sun and the optimum time interval of the panel’s movement. The optimum time intervals or panel movement can change the rate of input energy to the panel surface in Iran. For this purpose, a neural network has been trained to estimate the intensity of solar radiation in Iran. After model validation, the intensity of solar radiation has been estimated by selecting adequate geographical regions. Based on the intensity of sunlight, Iran has been divided into ten regions. In these regions, 40 cities have been randomly selected to study the effect of the panel’s angle variations within appropriate time intervals, as well as equal time intervals. The results show that the choice of the mounting system with the possibility of five angles’ implementation can increase the amount of solar energy between 3.9% and 7.4%. Compared to this number of angles at the equal time intervals, the amount of incoming solar energy has increased by 3% to 7%. In the first and second cases, the area of the power plant increases by about 12% to 24% compared to the yearly optimum tilt angle. Moreover, the amount of radiation incoming to the panel with the optimum operating angle is in alignment with the results of PVsyst software.

Clay bricks are extensively used as building material worldwide. Natural soil deposits are in constant reduction due to the frequent use of clay to manufacture bricks. About 1600 billion bricks are produced annually by the consumption of millions of tons of natural resources. The prime focus of this study is to assess the feasibility of using a composite mixture of waste brick powder (WBP) and waste ceramic powder (WCP) as a replacement for depleting natural resource “clay” in brick manufacturing. Based upon the previous studies, the replacement levels were kept as (4 + 5)%, (8 + 10)%, and (12 + 15)% of WCP and WBP, respectively. The brick specimens were evaluated in terms of compressive strength, modulus of rupture, density, water absorption, efflorescence, apparent porosity, resistance to chemical attack and sulfate attack, and freeze-thaw resistance. The study reveals that about 27% of clay can be replaced with ceramic waste powder and waste brick powder, which can preserve a massive amount of natural clay without compromising the quality of the bricks.

Published: September 2021

The deployment of renewable energy sources (RES) is an essential strategic objective of sustainable energy development in Estonia, Latvia and Lithuania. Their growing contribution to the total primary energy supply can significantly facilitate the transition to a low-carbon economy. The paper provides findings from an in-depth comparative analysis of RES deployment trends during 2010–2019 in the Baltic countries in the context of energy policy documents of the European Union (EU). The dynamics of targeted RES indicators according to the Renewables Directive 2009/28/EC and National Programmes and the role of renewable energies in mitigating climate change are analysed. A key role of the heating and cooling sector in deploying RES is highlighted and a necessity to implement radical changes in the transport sector of the Baltic countries is revealed. The paper examines changes in energy-related greenhouse gas (GHG) emissions and the impact of driving factors in Estonia, Latvia, Lithuania and other countries of the Baltic Sea Region (BSR). The Kaya identity and the logarithmic mean Divisia index (LMDI) method are used for the decomposition analysis. Based on the analysis conducted, the impact of population change, economic growth, decline of energy intensity, RES deployment and reduction of emission intensity on change of GHG emissions in countries of the BSR and, on average, in the EU-27 during 2010–2019 is revealed.

Published: September 2021

E-commerce industry has witnessed a phenomenal growth globally due to the sudden spread of the COVID-19 pandemic and the advancement of mobile Internet technology, with fast adaption of online shopping technologies by the customers. Previously, online shopping was only available in a few product categories and to a select group of consumers. The COVID-19 guidelines related to safety, physical distancing, closure, lockdown, and other restrictions have insisted that consumers shop online. Because of e-commerce growth, the grocery (FMCG) industry is also equipped with advanced technologies such as the Internet of Things (IoT), cloud computing, and block chain technology. This paper analyzes the UTAUT2 model and its influence on perceived risk and consumer trust in online purchase intention of grocery categories of products among Indian customers. We tried to analyze the growth potential of new technologies in grocery retail and formulated the hypotheses. The results showed that the spread of COVID-19 pandemic had a significant influence on the online shopping behavior of Indian customers. The outcome of the study partly assists businesses in understanding the impact of the factors of consumer adaption of technology, perceived risk associated with online transaction, consumer trust in online technologies and consumer online purchase intention of grocery products. To promote e-commerce in India, the current study suggests that marketers should try to develop consumer trust and lowering the perceived risk associated with online shopping. Some management implications and future area of study based on empirical findings are also highlighted in the present research work.

For the Ukrainian population, there are factors surrounding the choices and preferences one must consider when changing permanent residence. Smart residential areas should be built according to Ukrainian legislation and global innovations, which would reduce administrative dislocations, the load on megalopolises, and negative anthropogenic impacts, and should be based on the increase in energy efficiency and reducing waste. We analyzed the core principles of designing smart residential areas and concluded that constructing cutting-edge residential areas should involve private investments in order to avoid shadow schemes and irrational use of funds (in the Ukraine, the share of the shadow market is more than 50%). Research shows that, as humans inhabit a three-dimensional space, it is possible to predict migration and other permanent residence/behavioral responses, the analysis of which allows controlling migration flows and improves the conditions of Ukraine’s small residential areas based on decarbonization. We conclude that energy saving systems can reduce consumption in a city by 60% and improve Ukraine’s ecosystem. Research also shows that reducing “dislocation”, in terms of population density, by creating open, innovative, eco-friendly environments based on green economy principles, can provide innovative development maps and economic, social, and cultural population growth, decreasing the load on big cities/regional economies, and encourage the restoration of sales markets and production after the COVID-19 pandemic. We developed a model to assess the innovativeness of residential areas, apply alternative methods of energy generation, and analyze the impact of the energy production and consumption market in Europe (with recommendations for the Ukraine). This article estimates energy intensity indicators of the gross domestic product in the Ukraine and in Europe, offering methods to decrease energy dependence and increase energy efficiency in the Ukraine, by adopting alternative energy sources (e.g., biohydrogen out of residues, air, and solar energy), and enhancing environmental legislation.

Published: September 2021

The increasing threat to sustainable agriculture is a major concern of planners worldwide. Human population growth together with increasing food requirements and competition for land use is leading to land scarcity for agricultural purposes. Farm size influences the extent of the adoption of mechanization and modern methods of farm management practices, which in turn results in increased productivity, production efficiency and agricultural income. We studied changes in macroeconomic factors such as dependency on agriculture, growth of the sector, the pattern of landholdings and tenure rights across major agriculturally important countries, as well as the priority of agriculture for the national economy (i.e., the share of agriculture in the national income) and its relationship to changes in farm size. The data on the percentage of area under farming, population growth, size of the agricultural workforce and other social dimensions from 24 countries of different geographical sizes were analysed. We used parameters such as the extent of changes in cropland, family-owned land, the agricultural workforce and their productivity, number of holdings and their distribution, women-headed holdings and finally total and per capita agricultural income, and measured the changes over time and space. The published data from national and international sources were used to establish the relationship between farm size and farm efficiency measured through the selected parameters. The results clearly establish that the size of farm holdings had an inverse relationship with the population dependent on agriculture, share of agriculture in national income and tenure rights. Australia had the largest average agricultural landholding (3243 ha), while India and Bangladesh had the lowest (1.3 and 0.3 ha, respectively). The inequality in the distribution of farmland ownership was greater in developed countries than in developing countries. Female farmland ownership was less than 20% in most developing countries and the relationship between the number of farm households and farm outcomes was found to have weakened over time. India, a developing as well as an agriculturally important country, was subjected to detailed analysis to understand the spatiotemporal dynamics of the size, distribution and ownership patterns of agricultural landholding.
Offsetting the Impact of CO2 Emissions Resulting from the Transport of Maiêutica’s Academic Campus Community
Authors: Veludo Guilherme , Cunha Manuel , Sá Maria Manuel , Oliveira-Silva Carla
Published: September 2021

The authors aim to investigate the number of trees necessary to capture the CO2 emissions from house–campus travelling, to and from the Maiêutica Academic Campus in the north of Portugal. A sample of the academic community was given an online survey in order to assess mobility practices. Based on the data collected, CO2 emissions, as well as the number of trees necessary to mitigate these emissions, were calculated. The authors estimate that the total emissions resulting from house–campus commutes amount to 2937 tCO2 year−1. To mitigate this amount of carbon dioxide, 138 ha would be necessary to plant 96,539 trees, according to the species’ respective CO2 removal rates. The estimated tree area necessary to neutralize the community’s mobility related CO2 emissions is so high that other alternatives must be considered: a preferred use of public transportation, carpool system, online theoretical classes, rescheduling timetables, green roofs installation, and photovoltaic panels.
The Double Phospho/Dephosphorylation Cycle as a Benchmark to Validate an Effective Taylor Series Method to Integrate Ordinary Differential Equations
Authors: Borri Alessandro , Carravetta Francesco , Palumbo Pasquale
Published: September 2021

The double phosphorylation/dephosphorylation cycle consists of a symmetric network of biochemical reactions of paramount importance in many intracellular mechanisms. From a network perspective, they consist of four enzymatic reactions interconnected in a specular way. The general approach to model enzymatic reactions in a deterministic fashion is by means of stiff Ordinary Differential Equations (ODEs) that are usually hard to integrate according to biologically meaningful parameter settings. Indeed, the quest for model simplification started more than one century ago with the seminal works by Michaelis and Menten, and their Quasi Steady-State Approximation methods are still matter of investigation nowadays. This work proposes an effective algorithm based on Taylor series methods that manages to overcome the problems arising in the integration of stiff ODEs, without settling for model approximations. The double phosphorylation/dephosphorylation cycle is exploited as a benchmark to validate the methodology from a numerical viewpoint.
Structural Investigation into Magnetic Spin Orders of a Manganese Phosphatic Oxyhydroxide, Mn5[(PO4)2(PO3(OH))2](HOH)4

Published: September 2021

The ferri- and antiferromagnetic structures of a hureaulite-type synthetic compound, Mn2+5(PO4)2(PO3(OH))2(HOH)4, were elucidated by high-resolution neutron powder diffraction in combination with magnetic susceptibility and heat capacity measurements. At 6.17 K, the paramagnetic phase (space group: C2/c) transforms to inherit a ferrimagnetic order (magnetic space group: C2′/c′), followed at 1.86 K by an incommensurately modulated antiferromagnetic order (magnetic superspace group: P21/c.1′(α0γ)00s with the propagation vector k(0.523(2), 0, 0.055(1)). In the ferrimagnetic state, antiferromagnetic interactions are dominant for both intra and inter pentamers of Mn2+(O, HOH)6 octahedra. Differently aligned spin-canting sublattices seen in the ferrimagnetic models at 3.4, 4.5, and 6.1 K explain a weak ferromagnetism in the title compound. The observation of magnetic moments vigorously changing in a small temperature range of 6.1–1.5 K adumbrates a high complexity of interplaying structural and magnetic orders in this manganese phosphatic oxyhydroxide.

The purpose of this study was to investigate the combined effects of aflatoxin B1 and ochratoxin A on protein expression and catalytic activities of CYP1A2, CYP2E1, CYP3A29 and GSTA1 and the preventive effect of dietary byproduct antioxidants administration against these mycotoxin damage. Three experimental groups (E1, E2, E3) and one control group (C) of piglets after weaning (TOPIGS-40 hybrid) were fed with experimental diets for 30 days. A basal diet containing normal compound feed for starter piglets was used as a control treatment and free of mycotoxin. The experimental groups were fed as follows: E1—basal diet plus a mixture (1:1) of two byproducts (grapeseed and sea buckthorn meal), E2—the basal diet experimentally contaminated with mycotoxins (479 ppb OTA and 62ppb AFB1) and E3—basal diet containing 5% of the mixture (1:1) of grapeseed and sea buckthorn meal and contaminated with the mix of OTA and AFB1. After 4 weeks, the animals were slaughtered, and tissue samples were taken from liver and kidney in order to perform microsomal fraction isolation, followed by protein expression and enzymatic analyses. The protein expressions of CYP2E1 and CYP3A29 were up-regulated in an insignificant manner in liver, whereas in kidney, those of CYP1A2, CYP2E1 and CYP3A29 were down-regulated. The enzymatic activities of CYP1A2, CYP2E1 and CYP3A29 decreased in liver, in a significant manner, whereas in kidney, these increased significantly. The co-presence of the two mycotoxins and the mixture of grape seed and sea buckthorn meal generated a tendency to return to the control values, which suggest that grapeseed and sea buckthorn meal waste represent a promising source in counteracting the harmful effect of ochratoxin A and aflatoxin B.

Published: September 2021

The occurrence of mycotoxins on grapes poses a high risk for food safety; thus, it is necessary to implement effective prevention methods. In this work, a metagenomic approach revealed the presence of important mycotoxigenic fungi in grape berries, including Aspergillus flavus, Aspergillus niger aggregate species, or Aspergillus section Circumdati. However, A. carbonarius was not detected in any sample. One of the samples was not contaminated by any mycotoxigenic species, and, therefore, it was selected for the isolation of potential biocontrol agents. In this context, Hanseniaspora uvarum U1 was selected for biocontrol in vitro assays. The results showed that this yeast is able to reduce the growth rate of the main ochratoxigenic and aflatoxigenic Aspergillus spp. occurring on grapes. Moreover, H. uvarum U1 seems to be an effective detoxifying agent for aflatoxin B1 and ochratoxin A, probably mediated by the mechanisms of adsorption to the cell wall and other active mechanisms. Therefore, H. uvarum U1 should be considered in an integrated approach to preventing AFB1 and OTA in grapes due to its potential as a biocontrol and detoxifying agent.
WRKY Transcription Factors in Cassava Contribute to Regulation of Tolerance and Susceptibility to Cassava Mosaic Disease through Stress Responses
Authors: Freeborough Warren , Gentle Nikki , Rey Marie E.C.
Published: September 2021

Among the numerous biological constraints that hinder cassava (Manihot esculenta Crantz) production, foremost is cassava mosaic disease (CMD) caused by virus members of the family Geminiviridae, genus Begomovirus. The mechanisms of CMD tolerance and susceptibility are not fully understood; however, CMD susceptible T200 and tolerant TME3 cassava landraces have been shown to exhibit different large-scale transcriptional reprogramming in response to South African cassava mosaic virus (SACMV). Recent identification of 85 MeWRKY transcription factors in cassava demonstrated high orthology with those in Arabidopsis, however, little is known about their roles in virus responses in this non-model crop. Significant differences in MeWRKY expression and regulatory networks between the T200 and TME3 landraces were demonstrated. Overall, WRKY expression and associated hormone and enriched biological processes in both landraces reflect oxidative and other biotic stress responses to SACMV. Notably, MeWRKY11 and MeWRKY81 were uniquely up and downregulated at 12 and 67 days post infection (dpi) respectively in TME3, implicating a role in tolerance and symptom recovery. AtWRKY28 and AtWRKY40 homologs of MeWRKY81 and MeWRKY11, respectively, have been shown to be involved in regulation of jasmonic and salicylic acid signaling in Arabidopsis. AtWRKY28 is an interactor in the RPW8-NBS resistance (R) protein network and downregulation of its homolog MeWRKY81 at 67 dpi in TME3 suggests a negative role for this WRKY in SACMV tolerance. In contrast, in T200, nine MeWRKYs were differentially expressed from early (12 dpi), middle (32 dpi) to late (67 dpi) infection. MeWRKY27 (homolog AtWRKY33) and MeWRKY55 (homolog AtWRKY53) were uniquely up-regulated at 12, 32 and 67 dpi in T200. AtWRKY33 and AtWRKY53 are positive regulators of leaf senescence and oxidative stress in Arabidopsis, suggesting MeWRKY55 and 27 contribute to susceptibility in T200.
Hydrological Similarity-Based Parameter Regionalization under Different Climate and Underlying Surfaces in Ungauged Basins
Authors: Wang Huaijun , Cao Lei , Feng Ru
Published: September 2021

Hydrological similarity-based parameter regionalization is the dominant method used for runoff prediction in ungauged basin. However, the application of this approach depends on assessing hydrological similarity between basins. This study used data for runoff, climate, and the underlying surface of the Hulan River Basin and Poyang Lake Basin to construct a novel physical hydrological similarity index (HSI). The index was used to compare the efficiency of transfer of the parameters of commonly used regionalization methods and to finally apply parameters to ungauged basins. The results showed that: (1) Precipitation is the main climatic factor regulating magnitude of runoff in the Poyang Lake Basin. Spring runoff in Hulan River Basin was regulated by precipitation and temperature. (2) The GR4J and CemaNeigeGR4J models achieved reasonable simulations of runoff of Poyang Lake Basin and Hulan River Basin. Although CemaNeigeGR4J considers snowmelt, the model simulations of spring runoff in the Hulan River Basin were not accurate. (3) There was a significant correlation between climate, the underlying surface, and hydrological model parameters. There were fewer significant correlations between environmental factors and between environmental factors and hydrological model parameters in the Hulan River Basin compared to those in the Poyang Lake Basin, possibly due to less sub-basins in the Hulan River Basin. (4) The HSI based on a combination of principal component analysis and the entropy method efficiently identified the most similar gauged basin for an ungauged basin. A significant positive correlation existed between the HSI and parameter transfer efficiency. The relationship between the HSI and transfer efficiency could be represented by logistic regression and linear regression in the Poyang Lake Basin and Hulan River Basin, respectively. The HSI was better able to quantify the hydrological similarity between basins in terms of climate and underlying surface and can provide a scientific reference for the transfer of hydrological model parameters in an ungauged basin.
Estimating the Importance of Hydrologic Conditions on Nutrient Retention and Plant Richness in a Wetlaculture Mesocosm Experiment in a Former Lake Erie Basin Swamp
Authors: Jiang Bingbing , Mitsch William J. , Lenhart Chris
Published: September 2021

The western basin of Lake Erie, the shallowest of the Laurentian Great Lakes in North America, is now plagued by harmful algal blooms annually due to nutrient discharges primarily from its basin. Water quality was impacted so significantly by toxic cyanobacteria in 2014 that the city of Toledo’s water supply was shut off, affecting hundreds of thousands of residents. A new agricultural land management approach, ‘wetlaculture (=wetland + agriculture)’, has a goal of reducing the need for fertilizer applications while preventing fluxes of nutrients to downstream aquatic ecosystems. A wetlaculture mesocosm experiment was set up on agricultural land near Defiance, Ohio, on the northwestern edge of the former ‘Great Black Swamp’. The mesocosms were randomly assigned to four hydrologic treatments involving two water depths (no standing water and ~10-cm of standing water) and two hydraulic loading rates (10 and 30 cm week−1). Nearby agricultural ditch water was pumped to provide weekly hydraulic loading rates to the mesocosms. During the two-year period, the net mass retention of phosphorus from the water was estimated to have averaged 1.0 g P m−2 in the wetland mesocosms with a higher hydraulic loading rate, while the highest estimated net nitrogen mass retention (average 22 g N m−2) was shown in the wetland mesocosms with 10 cm of standing water and higher hydraulic loading rate. Our finding suggests that hydrologic conditions, especially water level, contribute directly and indirectly to nutrient retention, partially through the quick response of the wetland vegetation community. This study provides valuable information for scaling up to restore significant areas of wetlaculture/wetlands in the former Great Black Swamp, strategically focused on reducing the nutrient loading to western Lake Erie from the Maumee River Basin.
Power Distribution Strategy for an Electric Bus with a Hybrid Energy Storage System
Authors: Zhang Yu , Li Kai , Cui Shumei , Sun Yutian
Published: September 2021

To address the power distribution problem that occurs in hybrid energy storage systems (HESSs) in electric vehicles, a fuzzy control distribution method is proposed in this paper, taking the vehicle demand power; supercapacitor power, PSC;; and lithium battery power, Pbat, as the inputs and the power distribution factor of the supercapacitor as the output to control the power distribution of the composite energy storage system, in addition to dividing the whole working condition into three time scales, namely, long, medium and short. In this study, we conducted a comprehensive analysis and comparison with typical control methods regarding the energy storage element output power, battery state of charge (SOC) change, energy flow diagram and power frequency. The simulation experiment results show that the proposed strategy is more effective in reducing the peak output power of the power battery, improving the effective power utilization rate of HESS and the effective energy utilization rate. In order to further verify the effectiveness of the control strategy, a pure electric bus power system test bench was built based on similar principles, and a representative time period under the driving conditions of the China city bus (CHTC-B) was selected, involving an acceleration process from 30 to 48 s (process 1), a uniform speed process from 636 to 671 s (process 2) and a regenerative braking process from 1290 to 1304 s (process 3), further verifying the effectiveness and feasibility of the proposed control strategy.

O Estágio tem grande importância na formação inicial docente, uma vez que permite o contato direto dos licenciandos com a realidade escolar, levando estes professores em formação inicial a vivenciarem o processo de ensino e aprendizagem sob a ótica docente. Dessa forma, objetiva-se relatar a vivência de licenciandos do Curso de Licenciatura em Educação do Campo da Universidade Federal de Catalão (EDUCampo/UFCAT) em um estágio na Educação de Jovens e Adultos (EJA), buscando-se refletir sobre a importância desta etapa na formação inicial dos licenciandos envolvidos. Esta análise se pauta em uma pesquisa qualitativa, tendo como instrumentos de coleta de dados o diário de campo e a entrevista com um professor da escola (preceptor). Por meio da análise dos dados, observou-se que a formação de alguns dos docentes desta escola não era específica para a área em que estavam atuando e que os docentes não vêm tendo acesso a uma formação continuada. As observações trouxeram uma nova percepção em relação às especificidades de uma EJA, oportunizando conhecer melhor essa modalidade de ensino, portanto enriquecendo a bagagem como futuros professores e possibilitando que se pautasse a elaboração de uma sequência didática mais contextualizada com a realidade dos alunos da escola campo. Assim, percebe-se que para uma atuação docente que garanta uma aprendizagem plena e crítica, é necessário se conhecer a realidade do alunado.
Complexidades do imaginário: Entre a palavra e a imagem.
Authors:   , Oliveira Marcelo Manhães de
Published: September 2021

A proposta desta tese consiste em um trabalho transdisciplinar, haja vista envolver outras áreas como as Artes-visuais, bem como recorre a alguns estudos da Psicologia, da Hermenêutica, da Fenomenologia e da Antropologia. O tema, o imaginário, parte da sua origem lexical, a imagem, procurando desenrolar o grande novelo que a envolve desde os primórdios da humanidade, os homens dos períodos paleolítico e neolítico, precursores das primeiras imagens desenhadas nas cavernas, retratando seus cotidianos, promovendo o surgimento dos primeiros mitos, oriundos de suas imaginações e que se consolidaram em seus imaginários. Nessa cadência de acontecimentos, procuro abordar o tema imagem em um aspecto mais amplo, indo além da concepção de ser apenas observadas no aspecto das representações figurativas. A imagem no campo mental, evoca a escrita e instiga a criatividade, ou, se em uma ordem contrária, é o que procura desvendar esta pesquisa. Assim, busco compreender o princípio do processo criativo, embasando-me em textos que compõem o corpus teórico que envolve o assunto, além de exemplificar alguns fenômenos com obras de alguns autores e experiências de criação literária envolvendo texto e ilustrações, nas quais eu mesmo participei. Pretendo encontrar caminhos que demonstrem a influência dos mitos na construção desses imaginários que, por sua vez, conduzem ao objeto final, que é a criação. Com isso, discuto as relações dos processos criativos de uma obra, em especial as que envolvem o tripé texto-ilustração-livro, bem como as relações entre os imaginários na tríade escritor-ilustrador-leitor. Nesta tese, as complexidades do imaginário não se atêm somente às origens do mito e suas influências sobre o homem moderno, nem tampouco às relações descritas entre a palavra e a imagem, mas procura identificar a influência excessiva das imagens provocadas pelas novas mídias na afetação sobre as crianças, as quais participaram de um projeto literário realizado em campo, no qual algumas tendências puderam ser observadas e que são relatadas no presente trabalho.

O presente texto problematiza: o que pode a imagem cinematográfica em encontro com professoras? Articula diferentes movimentos de professoras com as imagens cinema na tentativa de potencializar o pensamento em devires. Busca deslocar a imagem de uma educação dogmática, ao tecer linhas de fuga na composição de outras imagens de escola e de educação. O estudo constitui-se de movimentos de pesquisa cartográfica em escolas públicas do município de Vitória, ES. Em diálogo com Deleuze e Guattari, aposta nas redes de conversações com professoras no encontro com as imagens cinema, as quais se envolvem na produção de sentidos entre práticasdiscursivas, textos, narrativas, imagens, sons, silêncios e silenciamentos. As narrativas que emergem dos encontros com professoras, questionam as imagens de currículos, de docências e de infâncias que estão impostas para as escolas. Assim, o estudo aposta em diferentes imagens de pensamento como outras possibilidades de se pensar uma educação da diferença.
O LIMITE DA DÚVIDA: DELEUZE E O HOMEM DO SUBTERRÂNEO
Authors: Whitaker Tosato Caio
Published: September 2021

Pretende-se apresentar um breve desdobramento de uma problemática anunciada por Gilles Deleuze no terceiro capítulo de Diferença e repetição, (denominado A imagem do pensamento), que concerne ao homem do subsolo enquanto um personagem conceitual. Fiódor Dostoiévski, em sua novela Memórias do subterrâneo, apresenta, a partir do protagonista, uma reflexão a respeito dos fundamentos da ação humana. Dessa forma, elecritica as noções de lei da natureza e lei moral através de um método de dúvidas. Pode-se dizer que os questionamentos do homem do subsolo levam a dúvida ao limite, provocando o desabamento dos pressupostos da explicação da ação humana (seja uma lei natural, seja uma lei moral).

Este texto pretende provocar uma reflexão sobre como as medidas de isolamento social, decorrentes da pandemia do Covid-19, podem atravessar a dimensão dos corpos a partir de processos de reterritorialização dos afetos no presente. Utilizando a noção espinosiana de hecceidade, trabalhada por Deleuze e Guattari, em que o corpo é o conjunto de seus movimentos, repousos e pelos graus de potência dos afetos, busca-se aqui pensar de que maneira as restrições físicas e sociais da pandemia podem alterar as noções espaço-temporais individuais e coletivas.

O que pode um corpo em sessão? Essa pergunta nos movimentou a cinecartografar os curtas da sessão “O que pode um corpo?” apresentada na Mostra [em]curtas (2020). Em ziguezagues, deglutimos o que nos atravessou nos processos de construção da Mostra e também como espectadores dos filmes. À espreita em porosidades que possibilitam rizomar junto às potências que habitam as produções audiovisuais e que nos habitam. Cinecartografias que são permeadas por questões dos corpos, e gêneros, e sexualidades, e devires, e... Cinecartografias que nos deslocam, nos possibilitando ser outros, com filosofias e cinemas.

A infecção pelo vírus SARS-CoV-2 (COVID-19) tem sido relacionada a complicações neurológicas associadas ao sistema nervoso central e ao periférico. As hipóteses para tais efeitos incluem a passagem do vírus através da barreira hematoencefálica, além da invasão viral a células do endotélio vascular mediante ligação com receptor da enzima conversora de angiotensina 2 (ACE2). Foram relatados sintomas neurológicos não específicos, incluindo cefaléia, estado mental alterado, tontura, depressão do nível de consciência, ageusia, anosmia, mialgia e fadiga. A patologia em questão também foi correlacionada com diversas repercussões psiquiátricas, destacando-se depressão, ansiedade, insônia, transtorno de estresse pós-traumático, delirium e psicose. O tratamento na COVID-19 é alvo de amplo debate, sendo consenso a recomendação de analgésicos e antitérmicos para infecções leves. Nos casos graves, em que há necessidade de oxigênio suplementar ou ventilação mecânica, o corticosteróide sistêmico Dexametasona é associado a maior sobrevida.

DNA based approaches have become widespread in recent times to identify the origin of samples when its phenotypic characteristics are not distinguishable. This, in particular, applies to the leather industry wherein with an increase in duplicated embossing of grain patterns; there is a need to detect the animal origin of  commercial leather articles. Thus, the characterization of molecular markers that enables rapid detection of the leather source helps us in precise species identification. The present study aims to generate definite sequences between the four major species in the Bovidae family (Buffalo, Cow, Goat, and Sheep), which are the major players in the manufacture of leather products, especially in India. Based on specific mitochondrial sequences, a specific fragment of the mitochondrial 12SrRNA gene was amplified by PCR as a marker for species-level identification. By the maximum homogeneity, from the NCBI and BOLD database, the BLAST analysis of the sequences of amplicons from unknown sources, distinguish closely related species of the subfamilies Bovinae (buffalo and Cow) and Caprinae (sheep and goat) and this 12SrRNA based PCR-BLAST analysis is a good tool to identify the origin and control the quality of leathers that are being manufactured. The present study has optimized an approach for the extraction and amplification of DNA from the finished leather, which is one of the most significant challenges because of the vigorous processes encountered during their manufacture. The findings of the study have commercial value at large scale.

Dialdehyde starches with different aldehyde content from native corn starch were prepared by sodium periodate oxidation to be used as a tanning agent in leather making. For this purpose, native corn starch was oxidized with sodium metaperiodate in different molar ratios. After oxidation processes, the yields, solubility in water and aldehyde contents of the obtained dialdehyde starches were determined as well as structure characterizations by Proton Nuclear Magnetic Resonance Spectroscopy, Fourier Transform Infrared Spectroscopy and Gel Permeation Chromatography. Evaluating the gel permeation chromatography data, the dialdehyde starch samples which were thought to be in appropriate molecular weight/size to penetrate into skin fibers were selected to be used in the tanning process. Their tanning abilities were evaluated by investigating hydrothermal stabilities, filling and fiber isolation characteristics and physical properties determined by mechanical tests and organoleptically. From the evaluation of the results, it was revealed that sodium metaperiodate oxidized starches which have appropriate molecular weight and adequate aldehyde content has a remarkable tanning effect and can be utilized as a tanning agent with the advantages of not necessitating pickling process which means saving time and simplifying the production but more importantly offering an important advantage from an environmental point of view.

In the beamhouse, liming might directly affect the structure and performance of collagen, as well as the quality of resultant leather. However, the influences of composition and content of liming agents on liming mechanism are quite complicated. In this study, calcium hydroxide and urea were utilized in liming. The solution pH, hide swelling ratio and non-collagenous protein removal were quantitatively analyzed. The morphologies of both limed and fresh hides were studied by optical microscopy. The reaction mechanism of fiber opening up of cattle hides was analyzed and speculated by the combination of thermogravimetric analysis and Fourier transformation infrared spectroscopy. It was found that the fiber bundles of hides limed by urea/calcium hydroxide have a better opening up effect than that by pure calcium hydroxide. The mechanism of liming in an urea/calcium hydroxide solution system was proposed.

It makes sense to use environmentally friendly methods of degreasing in fur-making process. In this study, subcritical n-pentane was used to degrease wool fibers. Thermogravimetric analysis (TGA) was used to observe and analyze the properties of the subcritical n-pentane degreased wool fibers. The results showed that the thermal stability of the fibers increased. Fourier Transform Infrared (FTIR) spectroscopy was used to analyze the structural changes of macromolecular chains in wool fibers. It was found that when the pressure was higher than 0.4 MPa, the wool fibers underwent a conformational change with the α-helix changing to β-folding. If the pressure was as high as 0.6 MPa, the disulfide bonds in the wool fibers scale layer appeared to break. X-ray powder diffraction experiment was used to study changes in wool fiber aggregation morphology. It was demonstrated that the crystalline zone of wool fibers changed and the fibers index grew, from 22.89% to 30.19%. Field emission scanning electron microscopy and ultra-depth of field microscopy was used to analyze changes in the surface morphology of wool fibers. The results suggested that after the treatment, the wool fibers were not damaged and the impurities on the wool surface were reduced.

The quality of the raw animal skin decides the final quality of leather. Preservation processes of raw animal skins until leather making predominantly uses salting as a popular method owing to the bacteriostatic effect provided by salt. The detrimental impact caused by the usage of salt from the leather processing is well established. This necessitates the quest for developing an economical, efficacious and environment-friendly preservation system. The present work investigates the effects on the physical and chemical characteristics of the animal skin caused by the putrefactive bacteria with respect to time. Physical changes were studied using visual examination, SEM analysis, and histological staining techniques where the structural deterioration was evidently established. Changes in biochemical aspects were studied by observing degradation in proteoglycan levels and collagen from the goat skin taken at various time intervals. Furthermore, the microorganisms that were responsible for the degradation of various skin components were isolated from the skin over the period of 36 hours from flaying. The occurrence of collagen-degrading organisms within 6 hours of initiation of putrefaction and increased number of proteolytic and collagenolytic bacteria at the end of 36-hours observation were indicative of tremendous skin spoilage leading to deteriorated quality of raw material.

Published: September 2021

Hydrogen peroxide and sodium metaperiodate oxidation of starch and their possible utilization in tanning/retanning were examined in our previous studies. In the present part, accordingly with our previous findings, hydrogen peroxide and sodium metaperiodate oxidation products having appropriate molecular weight/size were selected and additionally carboxymethylated. The yields of the processes (carboxymethyl starches) were characterized comprehensively and the effect of carboxymethylation process on structures and tanning abilities were tried to be identified. The characterization results revealed that the carboxymethyl groups were successfully included into the structure and the water solubility of oxidized starches (especially periodate oxidized ones) increased by carboxymethylation process. From the evaluation of the tanning results and considering its properties i.e. gentle tanning effect with less astringency and correspondingly a relatively soft leather handle and smooth grain, it is concluded that dialdehyde carboxymethyl starch (CMS 1:0.7) can be utilized as yet another good alternative sustainable green tanning/retanning agent from starch.

Leather is three-dimensional matrix possessing unique properties which makes it more comfortable for daily use. Garments made from leathers are preferred choice owing to their multifaceted properties as compared to textiles in the colder regions. In the present study, an attempt has been made to evaluate the influence of phenolic syntan and synthetic fatliquor on the sewability and physical properties of post tanned leathers. From the experimental results, it is observed that the concentration of phenolic syntan and fatliquor influences leather sewability. Optical microscopic images of leathers also show that they are more compact and tighter with higher percentage of syntan. The study provides an insight in understanding the optimum usage of post tanning chemicals for better sewing properties without affecting the leather matrix adversely.
