Contributions of polyelectrolyte complexes and ionic bonding to performance of barrier films for packaging: A review
Authors: Hubbe Martin A.
Published: June 2021

Barrier films that are used on packages play an important role, especially in the protection of food products. Research is being carried out at an accelerating pace to replace petroleum-based plastic films, which do not biodegrade and are difficult to recycle. This review article considers publications related to the use of polyelectrolyte complexes (PECs) in barrier films as a strategy to decrease the permeation of oxygen and other substances into and out from packages. Research progress has been achieved in using combinations of positively and negatively charged polymers, sometimes together with platy mineral particles, as a way to restrict diffusion through packaging materials. In principle, the ionic bonds within PECs contribute to a relatively high cohesive energy density within such a barrier film, which can resist diffusion of various gases and greasy substances. Resistance to water vapor, as well as aqueous substances, represent important challenges for barrier concepts that depend on ionic bond contributions. Factors affecting barrier performance of PEC-based films are discussed in light of research findings.
A Review of Micellar Enhanced Ultrafiltration Technique in the Removal of Heavy Metals from Aqueous Solutions
Authors: Deniz ŞAHİN
Published: June 2021

The pollution of the aquatic ecosystems with heavy metal ions has become a global problem in recent years. Heavy metals normally occur in nature and are essential to life at trace levels. However, they can be toxic when their concentrations exceed the upper permissible limits. Heavy metal contaminated habitats have the ability to bioaccumulate in aquatic ecosystems, which, in turn, may enter into the food chain and lead to health problems. Therefore, it is necessary to remove these heavy metals from aquatic ecosystems. Several technologies are already in operation, but these conventional technologies involve high operational costs and may produce harmful impacts on aquatic ecosystems. Micellar enhanced ultrafiltration (MEUF) is an alternative technique to remove the trace concentrations of heavy metals from aquatic ecosystems. The uniqueness of MEUF is that it requires less energy due to low membrane cost and working pressure. Although various researchers have been carried out the MEUF study on the removal of heavy metal ions, few review papers indicate the factors on MEUF technique. That is the reason why this article focuses on reviewing of different parameters such as membranes, surfactants, operating conditions in the MEUF technique. In this technique, heavy metal ions’ removal even at lower concentrations has reached over 99%, which is evidently demonstrated in the presented review. The use of water-soluble ligands in combination with MEUF is a hybrid process to remove selectively and enhance the recovery of heavy metals. As understood in this study, an investigation is needed to treat highly concentrated solutions and real wastewater.

A corrupção como reflexo do modelo de doações
Authors: Alcure Milla Finotti
Published: June 2021

O sistema eleitoral brasileiro é marcado por relações de interesses firmadas entre os membros da elite, em que agentes políticos chegam ao poder através de campanhas financiadas por grupos empresariais. Durante o período de campanha, desprovidos de qualquer intuito democrático, e muitas vezes de forma ilegal, agentes privados efetuam exorbitantes doações de campanhas em favor de diversos candidatos e partidos políticos, que após eleitos, devem ter sua atuação pública pautada na retribuição pelo suporte financeiro ofertado, garantindo a proteção dos interesses daqueles que, em momento da campanha, tornaram possível a sua eleição. E desta maneira, legislações são criadas para favorecer certas castas, assim como regulamentos e fiscalizações são abrandadas, créditos em bancos estatais são facilitados, podendo ainda ocorrer o favorecimento ilegal em processos de licitação, o acesso a informações privilegiadas, dentre tantos outros meios de atuação lícitos ou ilícitos (mas sempre de adjetivação moral questionável). Deste modo, todo emaranhado de corrupção prejudica o desenvolvimento do país, afastando-o da justiça e isonomia, retirando o caráter constitucional do sufrágio. Utilizou-se nesta pesquisa, os métodos histórico e indutivo.
A (in)eficácia social dos direitos e garantias fundamentais das pessoas em situação de rua
Authors: Aquino de Souza Rayane , Cotomacci Gustavo
Published: June 2021

O objetivo do presente artigo consiste em analisar a eficácia social dos direitos e garantias fundamentais previstos em nosso ordenamento jurídico em relação às pessoas em situação de rua. Para isso, foi definido o conceito de eficácia, como também explanado sobre as normas constitucionais garantidoras de direitos, demonstrando assim, a importância e o valor dos direitos e garantias fundamentais para todos da sociedade. Contudo, cuidou de adentrar especialmente na realidade social das pessoas em situação de rua para identificar quem são, qual tem sido a atuação do Estado e quais são as normas específicas para efetivação de princípios fundamentais para assegurar a este grupo de pessoas às prerrogativas pertinentes a elas e qualquer ser humano. Assim, além de expor este contexto social à luz das normas jurídicas e doutrinas, foram apresentados dados obtidos em últimas pesquisas nacionais realizadas pelo IPEA e pelo MDS. Para tanto, também foi necessário adentrar especificamente nas políticas públicas como matéria fundamental para a concretização dos direitos fundamentais expostos. Após as análises feitas foi possível verificar falhas evidentes na aplicação dos direitos fundamentais ao que diz respeito à população em situação de rua, bem como o possível enquadramento ao Estado de Coisas Inconstitucional.
Aspectos gerais do percurso processual civil, e a aplicabilidade do parcelamento nas execuções de títulos judiciais
Authors: Bomfim Juliana Gramacho , Batista Daniela Pozza
Published: June 2021

O tema execução, de modo geral, constantemente engloba alguma polêmica, debate ou discussão, seja porque muitos devedores escondem seus bens do Judiciário para não cumprir com a obrigação que lhe são impostas, entre outros aspectos. Porém não será essa temática aqui abordada, e sim, o mecanismo do parcelamento quando em sede de cumprimento de sentença, tal mecanismo é assiduamente utilizado em compras e venda e renegociações de dívidas, fora da esfera do Judiciário. E em sede de cumprimento de sentença? Poderá ocorrer? Será benéfico e condizente com os princípios processuais? Para a referida análise, é preciso partir do início, faz-se necessária abordar o procedimento comum até o cumprimento de sentença e o procedimento da execução autônoma, pois o artigo tem como objetivo, a compreensão de todos acerca da análise, não somente, os estudiosos do direito. Partindo do princípio, teremos um respaldo razoável a fim de compreender os caminhos levarem a concepções distintas, acerca da temática, e, então, concluir que parcelar a mencionada dívida no Judiciário não é um ato injusto que vai atribuir mais tempo à satisfação da obrigação, a referida prática está mais para uma técnica respaldada em princípios processuais civis, viabilizando, por exemplo, um processo mais célere e eficaz ao credor e ao devedor. Importante frisar que o presente artigo não tem o intuito de interceder a favor do devedor, mas sim, de demonstrar que nem sempre a doutrina e a jurisprudência minoritária são infundadas, ou não merecem apreciação, tendo em vista que a formação de uma convicção, acerca de qualquer temática demanda pesquisa, analise crítica e também compreensão do assunto desde sua origem.

Published: June 2021

β-carotene known as an antioxidant, immunostimulant, provitamin A and natural colour is a popular additive used in food, cosmetics, and animal feed. Microbial β -carotene currently attracts attention thanks to its short production time and controllable process in comparing to the plant source. This study investigates the influences of the factors that enhance the accumulation of b-carotene in yeast strain Rhodotorula taiwanensis CT1. The addition of stressors including ethanol (0.2%), hydrogen peroxide (10mM) and NaCl (1M) to the 48h CT1 cultures improved the intracellular b-carotene to 2.2; 2.05 and 1.35 folds, respectively. Volumetric productivity of CT1 increased respectively 2.1; 2.0 and 1.1 folds.  As a metabolism regulator, citric acid (1%) added into 48h CT1 culture had a positive effect on intracellular b-carotene in CT1, resulted in its increase 1.78 folds. The highest β-carotene in CT1 was obtained when 1% Tween 80 was added in the culture: The intracellular b-carotene reached 337.56 ± 1.30 µg/g dry biomass, increased 2.84 folds; volumetric productivity achieved 15.38 ± 0.30 mg/L, increased 2.64 folds. However, the influence of addition time and appropriate concentration of study factors remained undetermined and need to be deeply investigated in further study.

Blooming meal: flower eating by the Blue-crowned Trogon Trogon curucui
Authors: Gonsioroski Gustavo , Sazima Ivan , Silva Marcos Augusto Rodrigues , Ubaid Flávio Kulaif
Published: June 2021

Abstract: Flowers provide birds with a range of dietary resources, although few data are available on flower eating for birds that have mixed diets. We report here a new food type for the Blue-crowned Trogon (Trogon curucui), describing two flower eating events. The individuals fed on the yellow trumpet tree flowers (Handroanthus spp.) at the peak of the dry season in the Cerrado and Pantanal biomes. The birds picked up the flowers by sally-glean flying and a brief hovering, and then perched on a nearby branch to swallow the flower whole. Florivory appears to be seasonal and, while a minor component of this species' diet, flowers may be an important alternative resource during periods when fruits are scarce.
Choosing from the repertoire of contention: Evidence from student protests in Latin America
Authors: Pavlic Rodolfo Disi
Published: June 2021

ABSTRACT Introduction: Activists mobilize using various protest strategies to advance their demands but few studies analyze protest events to explain their choice of peaceful, disruptive, and violent methods. This paper argues that when movements have few supporters and allies - major resources for mobilization - they privilege violent tactics. Conversely, when mobilizations have more participants and partners, protests are more likely to use peaceful or disruptive strategies. Materials and methods: The paper uses a mixed methods research design. From a quantitative perspective, it uses a dataset of 4,700 college student protests in Latin America to test the theoretical claims with logistic regressions. A case study of protest tactics and resources during the December 2014-January 2015 youth protests in Lima, Peru is used to illustrate how human resources shape the repertoire of contention. This qualitative section uses evidence from interviews as well as secondary data. Results: The results of the regression analyses partially support the theory, showing that more participants tend to make protests more peaceful and disruptive and less violent. The effect of certain allies, however, goes against theoretical expectations. As the case study shows, after a relatively violent first march, young activists in Lima organized themselves on a territorial basis, which both decreased the influence of political parties in the movement and increased the number of activists and actors involved, making subsequent demonstrations less violent. However, the case study also shows that the presence of specific political actors is inherently associated with more violent strategies. Discussion: This paper shows how the presence of allies and the number of demonstrators, as major resources available to social movements, shape the choice of tactics used in protest events. While more participants and the presence of allies makes events more contained, the evidence also suggests that both very large numbers of participants and the addition of disparate actors into a mobilization may promote violence.

ABSTRACT Objective: To evaluate the functional capacity of women with breast neoplasm undergoing palliative chemotherapy. Method: Cross-sectional study with an analysis of medical records of women with breast cancer undergoing palliative chemotherapy. Results: Out of one hundred evaluated records, most registered 50 years or older (66%), primary education (53%), an income of 1 to 2 minimum wages (87%), invasive ductal carcinoma (95%), positive hormone receptor (64%), and histological grade 1 and 2 (57%). Performance status 0 (49%), 1 (39%), and 2 (12%) were prevalent; these imply, respectively, active patients, with mild and moderate activity restriction. One to four chemotherapy schemes were associated with the inappetence (p =0.00) and weight loss (p =0.001) symptoms. The main complications were neuropathy (31%), medullary compression syndrome (21%), neutropenia (9%), and death (28%). Conclusion: Out of the analyzed women, 88% presented functional capacity 0 and 1, had no or mild restriction of daily activities, were multiply treated, and manifested manageable symptoms. Others, however, presented moderate to severe clinical complications during the treatment, progressing to exclusive palliative care or death.

Published: June 2021

To enhance oil recovery of high-viscosity oil deposits in the temperature range of 20-210 °C, a multifunctional composition with adjustable viscosity and high oil-displacing ability has been developed based on surfactants, aluminum and ammonium salts, an adduct of inorganic acid, carbamide and polyol. High buffer capacity of the composition in a wide pH range, 2.5-10 units pH, is provided by a complex of buffer systems: in the acidic range of pH, 2.5-4.0, the system “polyolboric acid and its salt”, in the alkaline range of pH – anammonia-borate buffer system. The composition has a low interfacial tension, a prolonged reaction with carbonate rocks, prevents the precipitation of insoluble reaction products, and increases the permeability of reservoirs. The composition is both oil-displacing and flow-diverting, it provides an enhance in the oil recovery factor, both due to the increase in the displacement factor and the the reservoir sweep by waterflooding or thermal steam stimulation

Las finanzas solidarias, a diferencia de las finanzas ortodoxas, se caracterizan por un enfoque social y relacional de los colectivos humanos; en esta línea, la presente investigación indaga sobre las bases sociales necesarias para la construcción de un modelo de gestión financiera congruente con el contexto de las comunidades rurales como las existentes en el departamento del Cauca (Colombia), atendiendo a sus experiencias de solidaridad y a los ejes de su realidad social y organizacional. Utilizando un enfoque mixto o triangulado, se fundamenta en metodologías de diagnóstico rural e investigación acción participativa. Como resultado se estructura una propuesta general que revaloriza los ejes de las denominadas finanzas solidarias.

VISION OF WOMEN IN CONTEXT APPEARANCES AND FUNCTIONING OF THE PYPHAGORIAN SCHOOL
Authors: Turenko Vitalii
Published: June 2021

The article, based on classical ancient sources and the most modern fundamental scientific works, explores and reveals the specifics of the existence of women in the early Greek philosophical school, founded by Pythagoras. There are three key reasons that led to the full existence of women along with men in the Pythagorean tradition: socio-political, doctrinal and vital. Accordingly, such a high status of women for the Pythagoreans is due not only to certain socio-political conditions of Greater Greece, or rather even the city of Croton, but also to the fact that the founder of this school, Pythagoras, unlike other early Greek thinkers, received philosophical knowledge from a woman, the Delphic Pythia Themistoclea. The doctrinal reason has been shown to be that Pythagoras himself preached the equality of women. If he had preached the opposite of the socio-political role of women in a given geographical region, he would not only not have been accepted, but even expelled. It is substantiated that the presence of women in this philosophical tradition is not a late Hellenistic fiction, but a real fact, based on the available sources of Aristotle's disciples – Dicaearchus and Aristoxenus, which testify to a rather ramified system of attracting women to the functioning of Pythagoreanism The proposed author's dichotomy of the representatives of this philosophical school known to us: pseudo-epigraphic and agraphic. Accordingly, the agraphic ones are known to us only by mentioning in certain ancient sources, while we know about the pseudo-epigraphic ones not only the names, but also preserved works and letters that are attributed to the Pythagorean thinkers.

South Asians in “Asia’s World City”: Postcolonial Identity Struggles and Art Participation in Hong Kong
Authors: Liu Hong Yu
Published: June 2021

Hong Kong, being the “Asia’s world city”, the government proclaimed itself committed to enhancing an inclusive society. However, critics have been questioning the effectiveness of its policy in bringing social inclusion as many South Asians in Hong Kong have to deal with post-colonial identity struggle in everyday life. By using participant observations and interviews, I will discuss how South Asians engage in community art which enables them to find other realms of (self-)representation beyond those delivered by the state and its failed promise of institutionalised assimilatory multiculturalism. Despite the policy shortcomings, a “dual” Hongkonger identity was found in minority descendants, facilitated by participating in community art activities. This article contributes to the knowledge of cultural inclusion, to understand its empowerment and potential conflicts in community art participation, and to invite more academic discussions on multiculturalism in the context of Hong Kong.
Professional and personal strategies of documentary filmmakers in Brazil: the case of the State of Rio de Janeiro and Minas Gerais.
Authors: Autissier Anne-Marie
Published: June 2021

Between 2012 and 2019, this qualitative sociological research was part of a documentary "boom" moment in Brazil, in terms of production and international recognition. Faced with a bottleneck in terms of their distribution, a growing number of festivals have opened up for documentaries, not counting the historical festival "É tudo Verdade" (São Paulo). This period also corresponds to a time when attempts at policies in favor of documentary films were made by the Federation and the Ministry of Culture (MinC) – public channel TV Brasil, TV Cultura, Doc.TV... These various advances have allowed the expression of a "black" cinema (Joel Zito Araujo), LGBT concerns (Karla Holanda), women’s rights (Helena Solberg and Susanna Lira) and the possibility for indigenous people to seize digital tools to reflect their own realities (Vincent Carelli, Video nas aldeias). Thus, while the Brazilian authorities were carrying out unfinished policies facing the weight of the private oligopolistic sector, it was interesting to analyze how documentary filmmakers developed their professional strategies. From this perspective, fourteen directors were the subject of semi-structured interviews in the state of Rio de Janeiro and three in Minas Gerais. In addition, producers and festival managers were also contacted. But the arrival of the Bolsonaro government caused a real rift. Against a backdrop of cultural war, fake news aimed at discrediting artistic circles, the takeover of the National Cinema Agency (ANCINE) and the abandonment of the São Paulo film library, cuts from major corporate sponsors, and beyond, Brazilian documentary filmmakers have found themselves strangers in their own country.

Background: Caesarean section is associated with risks of postoperative adhesions, incisional hernias (which may require surgical correction) and wound infections. The risk of the surgery may be increased due to a number of factors. The aim of the study was to study the effects of repeated caesarean sections and intra surgical difficulties.Methods: A cross sectional, observational, hospital-based study was done for all patients with repeat caesarean section for a period of 8 months. 190 women who have undergone one or more caesarean section of term gestation with a live foetus irrespective of amniotic fluid colour and amount with cephalic, breech, or transverse presentation elective and emergency caesarean sections and singleton or multiple pregnancies were selected for study.Results: In the present study the highest prevalence of previous C-section was seen in age group 20-29 years, which accounted for (88.5%). Complications are present in 42.1% patients in which adhesions was the most found complication. Adhesion between Parietal peritoneum and anterior surface of uterus is present in 26.3% patients, omentum and uterus is present in 25.8% patients, adhesiolysis was done in 28.9% patients. 80% complications were present in patients with one previous CS. The association was found to be statistically significant.Conclusions: Women undergoing repeated cesarean sections have a risk of increased morbidity due to increased intraoperative complications. To avoid this one should keep the cesarean section rate at reasonable limit with appropriate surgical techniques and to limit primary cesarean section rate.
