Authors: Santos Paulo Sérgio Medeiros dos , Travassos Guilherme Horta
Published: July 2021

Este artigo descreve uma avaliação experimental de uma técnica de inspeção de casos de uso baseada em checklist proposta na literatura e a sua inserção em um projeto de software real. A avaliação foi conduzida por meio de uma estratégia que combina dois tipos de estudos experimentais. Primeiro, um estudo controlado com estudantes de pós-graduação, objetivando avaliar preliminarmente a técnica checklist. Posteriormente, em um projeto real, onde se observou a sua utilização por meio da metodologia da pesquisa-ação. Em ambos os estudos, os resultados foram favoráveis à técnica checklist em relação à abordagem ad-hoc quando considerado o número de defeitos identificados – não foi observada diferença em relação ao tempo gasto. Um segundo resultado importante foi a identificação, apenas no projeto real, de uma diferença significativa de desempenho entre inspetores experientes e inexperientes. Através da análise das ações de pesquisa em campo, tem-se a indicação de que o fator experiência pode ser preponderante em inspeções baseadas em checklist.

Os requisitos de um software podem sofrer manutenções significativas durante o processo de desenvolvimento. Essas manutenções podem apresentar um custo elevado na medida em que o processo evolui, tanto por conta da complexidade em manter a rastreabilidade entre os requisitos, quanto por causa do impacto que uma alteração em um deles possa causar nos demais. Este trabalho propõe a geração automática de um grafo de requisitos através do mapeamento do grafo de dependências de módulos de uma aplicação e os requisitos por eles satisfeitos. Com isso, é possível utilizar os relacionamentos entre os módulos para manter a rastreabilidade entre os requisitos, permitindo apontar o impacto que a alteração em um deles possa causar nos demais. Um estudo de caso com 34 módulos e 24 requisitos é apresentado para exemplificar a técnica proposta.

Published: July 2021

The hair follicle is the unique organ that has the capacity of undergoing cyclic transformations following periods of growth (anagen), regression (catagen), and rest (telogen) regenerating itself to restart the cycle. The dynamic capacity of hair to growth and rest enables mammals to control hair growth and length in different body side and to change their coats. Unlike what is observed in many animals in which the pelage synchronously passes from one phase of the cycle to other all stages of growth cycle are simultaneously found in the human pelage, the growth pattern is a mosaic where the hair cycling staging of one hair root is completely independent of it nearest hair follicle, meaning that each follicular unit (FU) can contain follicles in different stages at any given time. A variety of factors, such as nutritional status, hormones, exposure to radiations, chemotherapy or radiotherapy, environmental pollution or drugs may affect hair growth, and affects the number of hairs, this progressive hair loss has a cosmetic and social impact that often significantly affects social and psychological well-being of the patient that suffers from this hair loss. Although a number of therapies, such as finasteride and minoxidil, are approved medications, a wide variety of classes of phytochemicals and natural products, including those present in ginseng are being testing. The purpose of this chapter is to focus on study the potential of ginseng and its metabolites in hair loss.

Published: July 2021

In the historical pursuit of soft tissue augmentation, fat has seemed a natural choice for plastic surgeons. The use of fat transfer to replace volume or camouflage soft tissues is an increasingly popular method in craniofacial surgery and facial esthetics. Craniofacial malformations undoubtedly have a certain psychosocial effect. Children of early age are particularly vulnerable to comments, teasing, and harassment related to their appearance; therefore, improving the facial image is of great importance. We believe that volumetric lipoinjection represents an excellent alternative to obtain greater facial esthetic harmony, which directly increases patient self-esteem in children and adults.
A Monotonic Method of Split Particles
Authors: Yanilkin Yury , Shmelev Vladimir , Kolobyanin Vadim
Published: July 2021

The problem of correct calculation of the motion of a multicomponent (multimaterial) medium is the most serious problem for Lagrangian–Eulerian and Eulerian techniques, especially in multicomponent cells in the vicinity of interfaces. There are two main approaches to solving the advection equation for a multicomponent medium. The first approach is based on the identification of interfaces and determining their position at each time step by the concentration field. In this case, the interface can be explicitly distinguished or reconstructed by the concentration field. The latter algorithm is the basis of widely used methods such as VOF. The second approach involves the use of the particle or marker method. In this case, the material fluxes of substances are determined by the particles with which certain masses of substances bind. Both approaches have their own advantages and drawbacks. The advantages of the particle method consist in the Lagrangian representation of particles and the possibility of” drawbacks. The main disadvantage of the particle method is the strong non-monotonicity of the solution caused by the discrete transfer of mass and mass-related quantities from cell to cell. This paper describes a particle method that is free of this drawback. Monotonization of the particle method is performed by spliting the particles so that the volume of matter flowing out of the cell corresponds to the volume calculated according to standard schemes of Lagrangian–Eulerian and Eulerian methods. In order not to generate an infinite chain of spliting, further split particles are re-united when certain conditions are met. The method is developed for modeling 2D and 3D gas-dynamic flows with accompanying processes, in which it is necessary to preserve the history of the process at Lagrangian points.

Danube Delta: Water Management on the Sulina Channel in the Frame of Environmental Sustainability
Authors: Cretescu Igor , Kovacs Zsofia , Lazar Liliana , Burada Adrian , Sbarcea Madalina , Teodorof Liliana , Padure Dan , Soreanu Gabriela
Published: July 2021

The Danube Delta is the newest land formed by both transporting sediments brought by Danube River, which flows into the Black Sea and by traversing an inland region where water spreads and deposits sediments. Diurnal tidal action is low (only 8–9 cm), therefore the sediments would wash out into the water body faster than the river deposits it. However, a seasonal fluctuation of water level of 20 cm was observed in the Black Sea, contributing to alluvial landscape evolution in the Danube Delta. The Danube Delta is a very low flat plain, lying 0.52 m above Mean Black Sea Level with a general gradient of 0.006 m/km and only 20% of the delta area is below zero level. The main control on deposition, which is a combination of river, wind-generated waves, and tidal processes, depends on the strength of each one. The other two factors that play a major role are landscape position and the grain size distribution of the source sediment entering the delta from the river. The Danube Delta is a natural protected area in the South-Eastern part of Romania, declared a Biosphere Reserve through the UNESCO “Man and Biosphere” Programme. Water is a determining factor for all the human settlements in the Biosphere Reserve, the whole Danube Delta being structured by the three branches of the Danube (Chilia, Sulina and Sfantu Gheorghe (Saint George)). Our case study is focused on the Sulina branch, also named Sulina Channel, which offers the shortest distance between the Black Sea (trough Sulina Port) and Tulcea (the most important city of the Danube Delta from economic, social and cultural points of view) for both fluvial and marine ships. The improvement of water resources management is the main topic of this chapter, in terms of water quality indicators, which will be presented in twenty-nine monitoring points, starting since a few years ago and updated to nowadays. During the study period, significant exceedances of the limit value were detected in case of nitrate-N (3.9–4.6 mg/L) at the confluence (CEATAL 2) with the Saint George branch and in the Sulina Channel after the Wastewaters Treatment Plant (WWTP) discharge area, as well as near two settlements, namely Gorgova and Maliuc. The higher concentrations of Nitrogen-based nutrients were caused by the leakage from the old sewage systems (where these exist) and the diffuse loads.

Inappropriate use of CS can have profoundly negative consequences for women and the broader community. A recent meeting of the International Confederation of Midwifes, the International Federation of Gynecologists and Obstetrics and the Gates Foundation to discuss the impact of rising CS rates on maternal and infant mortality in LMICs highlights the international importance of the issue. Knowledge of CS determinants is a first step in the effort to define strategies to reduce unnecessary CSs. Previous studies showed that the main reasons for performing CS are clinical factors. However, non-clinical factors such as demographic, health system factors, organizational variables were overlooked determinants that best predicted which women have a higher risk of CS.

Published: July 2021

Terahertz (THz) technology has attracted tremendous attention recently due to its promising applications in various domains such as medical, biological, industrial imaging, broadband, safety, communication, radar, space science, and so on. Due to non-availability of powerful sources and highly sensitive and efficient detectors, the so-called THz gap remains largely unfilled. Despite seamless efforts from electronics and photonics technology researchers, the desired level of technology development to fill the THz gap still remains a challenge. GaN-based HEMT structures have been investigated as potential THz sources and detectors by a number of researchers. This chapter presents a very new and versatile mechanism for electrical tuning of intersubband transitions (ISBT) GaN high electron mobility transition (HEMT) devices. ISBT phenomena are usually demonstrated in photonic devices like a quantum cascade laser (QCL). Here we explore ISBT in an electronic GaN HEMT device. Conventional photonic devices like a QCL are operated at cryogenic temperature to minimize thermal effect. Tuning the conduction band through external gate bias is an advantage of an HEMT device for room temperature (RT) THz applications. This chapter demonstrates the theoretical and experimental novel ISBT phenomenon in GaN HEMT is for potential ambient applications in the THz range.

Perceptions, Attitudes, and Interests of Architects in the Use of Engineered Wood Products for Construction: A Review
Authors: Emre Ilgın Hüseyin , Karjalainen Markku
Published: July 2021

Increased use of engineered wood products (EWPs) and thus decreasing share of non-biobased materials such as concrete reduces the impact of buildings on the climate by mitigating the primary energy use and greenhouse gas emissions in construction. A construction project includes many parameters, where the selection of construction material is one of the crucial decisions with its numerous criteria e.g. cost, strength, environmental impact. Furthermore, this complicated process includes different parties such as architects, engineers, contractors. Architects are among the key decision-makers in material selection, and their perceptions influence what they propose and hence an increase in wood construction. In literature, many studies have been conducted on the technological, ecological, economic aspects of EWPs, while limited studies are focusing on EWPs for construction from stakeholders’ perspective. In this chapter, architects’ attitudes towards the use of EWPs in buildings were scrutinized.
Petrology and Geochemistry of Nakora Ring Complex with Emphasis on Tectonics and Magmatism, Neoproterozoic Malani Igneous Suite, Western Rajasthan, India
Authors: Kumar Naresh , Sharma Radhika
Published: July 2021

The present contribution reports on the field, petrographical and geochemical observations of the volcano-plutonic rocks of the Nakora Ring Complex (NRC) from the Neoproterozoic, Malani Igneous Suite (MIS) (Northwestern Peninsular India) and confers about their magmatic evolution and tectonic implications. Three magmatic phases are notable in the NRC which is Extrusive, Intrusive and Dyke phase where with small quantities of basaltic flows was initiated and accompanied by extensive/voluminous acidic flows. Petrographically, rhyolite shows flow bands, porphyritic, spherulitic, aphyritic and perlitic textures whereas basalt flows are distinguished by the presence of labradorite in lath-shaped crystals (plagioclase feldspar) and clinopyroxene (augite). The presence of high silica and total alkalis in NRC rocks, as well as high field strength elements (HFSE), enrichment of trace elements and negative anomalies of Sr., Eu, P, and Ti indicates that the emplacement of the lava flows was controlled by complex magmatic processes such as fractional crystallization, crustal contamination and partial melting. The association of basalt-trachyte-rhyolite means that the magma chamber was supplied a significant amount of heat to the crust before the eruption. Moreover, a volcanic vent was also reported at NRC where rhyolite was associated with agglomerate, volcanic breccia, perlite and tuff. The current research proposed that the Neoproterozoic magmatism at NRC was controlled by rift-related mechanism and produced from crustal source where the heat was supplied by mantle plume.

Authors: Lastra-Bravo Javier
Published: July 2021

The indigenous peoples are distributed in all regions of the world, representing more than 6% of the world’s population. According to UN data, the pandemic has disproportionately affected indigenous groups, aggravating the structural inequalities and processes of widespread historical discrimination and exclusion present in the Global South, for example, high rates of extreme poverty, social exclusion, high prevalence of the disease, and limited and in some cases non-existent access to health care. Also, indigenous peoples have a great wealth of knowledge, traditional practices, cultural forms, and access to natural resources, as well as forms of collective social organization and community life that result in resilience factors in response to adversity and uncertainty. In this way, the chapter focuses from a descriptive-analytical approach on the situation of indigenous peoples and the pandemic, analyzing the forms of responses, their resilient action in the face of uncertainties and structural exclusions in the Global South.
Marek’s Disease Is a Threat for Large Scale Poultry Production
Authors: Kozdruń Wojciech , Samanta Niczyporuk Jowita , Styś-Fijoł Natalia
Published: July 2021

Marek’s disease (MD) is one of the widespread infectious diseases that causes huge losses in large-scale poultry production. This is due to weight loss, poorer feed conversion and an increased number of deaths among infected birds. The etiological agent is a Marek’s disease virus (MDV) belonging to the Herpesviridae family. It is mainly described in poultry, however, it is also found in geese. There are three MDV serotypes, and four patotypes within serotype 1. Currently, Marek’s disease is very rare in its classical form. There are non-specific clinical symptoms, and anatomopathological changes are mainly observed in the liver, spleen and the reproductive system. This may be due to the evolution in the pathogenicity of MDV field strains over the past several decades. The presence of MDV and number of molecular diagnostic tests based on the detection of viral nucleic acids and viral proteins is already found in birds that have several weeks old. Laboratory diagnostics are based mainly on molecular biology (mainly PCR) methods. The only relatively effective method instead of biosecurity measures, of preventing MD is prophylactic vaccination of 1-day-old chickens or in ovo vaccination. Nevertheless, Marek’s disease is still recorded in poultry flocks around the world, with estimated losses reaching several million dollars.

Authors: Hariri Rabeeh , Bakhtiary Amir-Hoshang , Mirmohammadkhani Majid
Published: July 2021

Background: Lateral ankle sprain is a common injury resulting from a rapid supination moment that damages the lateral ligaments and cartilaginous surfaces and contributes to the deterioration of functional ankle stability and balance among individuals. Objectives: This study aimed to investigate the immediate effect of Kinesio Taping (KT) on the balance performance of patients with chronic ankle sprains. Methods: This randomized, single-blind, parallel-group study was performed using the allocation concealment method. Sixty individuals (27 males and 33 females) with a history of ankle sprain were recruited and randomly assigned to one of the experimental (KT; n = 30) or control (non-KT; n = 30) groups. The intervention continued for two consecutive days, including four assessment sessions before and after taping on the first day and before and after removing KT on the second day. The mean and standard deviation (SD) of the center of pressure (COP) displacement and the velocity and SD of COP displacement were measured in the ant-post and med-lat directions following inversion and anterior perturbations. For data analysis, analysis of variance (ANOVA) test was performed using SPSS software version 22. This study was registered in the Iranian Registry of Clinical Trials (IRCT2013110415262N1). Results: The results of repeated measures ANOVA revealed an increase in the mean changes of COP displacement, velocity of COP displacement, and SD of COP displacement in the med-lat direction during inversion perturbation immediately after KT (P = 0.031, P = 0.005, and P = 0.011, respectively) and 24 hours after KT (P = 0.019, P = 0.002, and P = 0.009, respectively), compared to the control group. Moreover, during anterior perturbation, a significant increase was observed in the SD of COP displacement immediately and 24 hours after applying KT in the med-lat direction, compared to the control group (P = 0.022 and P = 0.016, respectively). Conclusions: Our findings revealed that KT might not improve the COP sway during perturbation in individuals with ankle sprains.

Published: July 2021

Hazelnut (Corylus avellana L.) is an economically very important fruit species cultivated in many countries. The world's largest producer and exporter of hazelnuts is Turkey. In Serbia, compared to other types of fruit, hazelnuts are grown on significantly smaller areas. In the last decade, hazelnut has become more interesting for the producers and there is a growing trend of increase of areas under this crop. Hazelnut is the host of numerous pathogens and pests that can cause significant economic damage in orchards. To date, there has been no comprehensive research on the causes of hazelnut diseases in Serbia, and the goal of our work was to determine the causes of some fungal diseases. In the period from 2017 to 2020, samples of hazelnut leaves and branches with symptoms of necrotic spotting were collected from a large number of plantations in Serbia. A large number of isolates were isolated from the collected samples for further determination. Based on the morphological and pathogenic properties of the isolates, the presence of phytopathogenic fungi from the genus Pestalotiopsis was determined.

Authors: Mihaljfi Teodora , Iličić Renata , Barać Goran , Savić Zagorka , Bagi Ferenc
Published: July 2021

The plum pox virus was discovered in Bulgaria between 1915 and 1918, hence the name "plum pox". Despite strict quarantine measures, as early as 1980s, this virus was widespread in whole Europe, but its presence was also confirmed in South and North America, Africa and Asia. The only continent where the infection with this virus has not been described yet is Australia. The presence of strains PPV-D, PPV-M and PPV-Rec has been confirmed in Serbia. The PPV-M strain spreads very quickly naturally, and it is considered as very dangerous for stone fruit trees. Trees infected with the plum pox virus do not decay, but bear fruit of poorer quality. Poorer quality of fruits reduces their market value, which leads to significant economic damage.

Published: July 2021

The protection of onions from the weeds and their negative impact in the field production is one of the most important measures. The onion is exceptionally succeptible to the weeds, especially in the first phases of the growth, considering the weak initial growth of the crop in comparison with the weeds. The seasonal dynamics of the onion weeds is not so noticeable like with the other crops, while the weeds that appear most frequently are: Amaranthus blitoides, Ambrosia artemisiifolia, Chenopodium album, Cirsium arvense, Convolvulus arvensis, Cynodon dactylon, Datura stramonium, Portulaca oleracea, Setaria glauca and Stellaria media. The chemical control measures mean the herbicide use before or after the emergence of the crop and the weeds. Before the emergence the herbicides based on aclonifen and pendimethaline can be used, while after the emergence herbicides based on fluroxypir, clopyralid, fluazifop-P-butyl, clethodim, quizalofop-P-ethyl, quizalofop-P-tefuryl and propaquizafop are used.

Authors: Filipović Jelena , Veljković Saša , Ognjanov Galjina
Published: July 2021

The relevance of the market of the organic products is constantly on the rise, however, consumers' awareness on this matter is still understudied. Aiming to bridge this gap, we conducted ethnographic research within 6 households in three different locations in a period of 12 months. The sample units have been selected as multi-person households in accordance with previously set criteria, including age, gender, geographic and socio-economic characteristics. Qualitative analysis as well as quantitative content analysis using NVivo software package have shown that organic has been among the most frequently mentioned words in the context of food labels, and it has been mostly taken into consideration when speaking about diary, fruit and meat products. The informants have shown high level of trust in organic labels. In line with that, we further discuss the importance of customer awareness with regard to labeling organic food products as well as positive attitudes toward labels in general, their readiness to read the labels, trust in labels and pay a higher prices when comparing with the conventional food products. Finally, we provide managerial implication of our findings and recommendations for further research.

A large variety of market relations are regulated by intellectual property rights, which represent legitimate monopolies correcting certain inefficiencies of a profit distribution on the market. In the following paper, the author examines the relations between design right and copyright using the comparative method. Firstly the author will analyze both resemblances and differences between these two intellectual property rights. The resemblance in protection object in particular makes available the cumulation of protected rights, in other words, the possibility of protecting industrial design by copyright, which will also be analyzed in the paper. Such work aims to comprehend the hybrid nature of design right as a right usually bypassed in a legal theory, and which is, in the author's opinion, especially interesting.
Atm infusion: Life in the cage of corporate culture
Authors: Bobić Aleksandar
Published: July 2021

This article is critical discourse on new redefined relations and usage of urban public spaces. Its starting points are the new relations between public and private spheres in contemporary U.S. cities which are based on corporate doctrine of consumer's lifestyle and phenomenon of exploitation of public resources, with the goal to accumulate more private capital. In that sense, focus was on tensions between public and private and phenomenon of the city centre where the private is imposed as public with its own rules of using and consuming instant entertainment and consumption. Phenomenon of public space as the only democratic space where everyone is equal, suddenly becomes phenomenon of the space for 'voluntarily' exploitation of people and resources with the idea of accumulating the private capital.
The Bauhaus Theater: Oskar Schlemmer's 'design in motion' concept
Authors: Nikolić Sanela
Published: July 2021

Bauhaus Theater obtained its most complete form through Oskar Schlemmer's artistic, pedagogical and theoretical work. The key problem for Schlemmer was the law of motion of the human body in space. His poetic implied anti narrative and antimimetic theater and also the widespread use of stage figures with the vivid articulation of space as his primary intentions. The human body on stage, converted into artificial figure, was the universal symbol of human being defined by opposites, which exists in a geometrical given space and determine it metaphysically. Use of term 'dance' in Schlemmer's play most titles, is consistent with the conception of stage event as a stage play of artificial figure in geometrical given space. Design in motion concept, which means the organization of the stage with specific mechanical-choreographic motions and working with form and color, determine the Schlemmer's stage as the absolute visual stage. Within the Bauhaus, Oskar Schlemmer's stage work has contributed to understanding of the theatrical event as the equally important artwork area for design of totality of space in which was established harmony between man, his life process and environment in which man exists.
Geoeconomic aspects of the cooperation between the Republic of Serbia and the people's Republic of China: Situation and perspectives
Authors: Božić-Miljković Ivana
Published: July 2021

The subject of this paper is the economic relations between the Republic of Serbia and the People's Republic of China from the beginning of the century until today. The development of these economic relations and cooperation is based on the long tradition of their good political and diplomatic relations. The relationship of these two countries towards the transition and different strategies in the implementation of this process are determinants of their economic success and the position they have in the global economy. The aspects of the economic cooperation between Serbia and China are analyzed in two categories in which this cooperation is most visible and in which its effects can be precisely expressed quantitatively: the cooperation in the field of foreign trade and in the field of investments. The basic hypothesis is that the economic relations between Serbia and China have been growing rapidly since the beginning of the century and that such a trend will continue in the future at the bilateral level, but also within the program of various cooperation platforms initiated by China and signed by Serbia. China's position in international institutions enables the protection of Serbia's territorial integrity, which is another important dimension of their mutual relations.

Broken test tubes for low-cycle fatigue testing of Nionicral 70 (NN-70) parent material (PM) steel and simulated heat-affected zones (SHAZ) were used to produce samples for cavitation resistance testing. Ultrasonic vibrational cavitation method (stationary sample method) was applied for testing in laboratory conditions. The test conditions and procedure, sample preparation and interpretation of results are defined by ASTM G32. The surfaces of the NN-70 PM and SHAZ steel samples were exposed to cavitation and damage monitoring over time. Measuring the weight loss of samples on the analytical balance after a certain time allowed us to determine the cavitation velocity as a measure of the material's resistance to the effect of cavitation. Scanning electron microscopy (SEM) was applied to monitor variations in surface morphology with changing test time. On the basis of the results of the cavitation resistance test, the morphologies of the surface damage for different exposure times of the cavitation of PM and SHAZ steel NN-70 samples were analyzed, as well as the mechanisms that led to the damage of the sample surfaces.
The short story of the miraculous daily resurrection of life in us
Authors: Jokanović Vukoman
Published: July 2021

The development of modern science in various fields today often exceeds the limits and ideas of the bravest philosophers and scientists of our time. And certainly the most intriguing areas of research are those based on the molecular basis of life processes. The complexity and complexity of the human body, countless intertwined feedback loops that regulate internal processes in the body and enable its survival, can best be interpreted at the micro and nano level, ie at the level of the cell and its subcellular structures. This opens up huge potentials for understanding and influencing living systems, but also unlimited challenges for science. The monograph "How cells live and die in us" is unique in many ways. The multidisciplinary procedure provides a comprehensive overview of the complexity of the human body, as well as its possible functioning at the cellular micro and nano level, ie at the level of molecules, atoms, nuclei, protons, etc. The story is inspired by Balasevic's line between the year of birth and the year of death.
Action potential-coupled Rho GTPase signaling drives presynaptic plasticity

In contrast to their postsynaptic counterparts, the contributions of activity-dependent cytoskeletal signaling to presynaptic plasticity remain controversial and poorly understood. To identify and evaluate these signaling pathways, we conducted a proteomic analysis of the presynaptic cytomatrix using in vivo biotin identification (iBioID). The resultant proteome was heavily enriched for actin cytoskeleton regulators, including Rac1, a Rho GTPase that activates the Arp2/3 complex to nucleate branched actin filaments. Strikingly, we find Rac1 and Arp2/3 are closely associated with synaptic vesicle membranes in adult mice. Using three independent approaches to alter presynaptic Rac1 activity (genetic knockout, spatially restricted inhibition, and temporal optogenetic manipulation), we discover that this pathway negatively regulates synaptic vesicle replenishment at both excitatory and inhibitory synapses, bidirectionally sculpting short-term synaptic depression. Finally, we use two-photon fluorescence lifetime imaging to show that presynaptic Rac1 activation is coupled to action potentials by voltage-gated calcium influx. Thus, this study uncovers a previously unrecognized mechanism of actin-regulated short-term presynaptic plasticity that is conserved across excitatory and inhibitory terminals. It also provides a new proteomic framework for better understanding presynaptic physiology, along with a blueprint of experimental strategies to isolate the presynaptic effects of ubiquitously expressed proteins.

OS ARARA (KARO TAP): MODOS DE SER E PROCESSOS DE RESSIGNIFICAÇÃO EM MEIO À COLONIZAÇÃO AMAZÔNICA
Authors: Alves Maria Isabel Alonso , Medeiros Heitor Queirós de , Arara Marli Peme
Published: July 2021

Este artigo intenciona mostrar o processo de colonização amazônica e as múltiplas tensões estabelecidas entre as populações indígenas e as diversas frentes de ocupação. Destaca-se a utilização de estudos bibliográficos que representam a possibilidade de verificar a história regional, bem como a história dos povos indígenas presentes na Amazônia brasileira, além de entrevistas narrativas. As narrativas das professoras indígenas contam a forma como se sentiram/sentem em relação à colonização e retratam o processo colonizador que afetou os povos indígenas na América Latina. Evidenciar o processo colonizatório exposto pelas professoras foi uma forma de ouvir suas versões sobre a história, muitas vezes, não consideradas pela visão ocidental/“oficial” dos fatos; dar visibilidade aos que não são vistos pela colonialidade.
