Drag kings – kamp czy zaangażowanie polityczne? Analiza zjawiska drag na przykładzie polskich drag kingów
Authors: Stasik Iwona
Published: September 2021

This article focuses on the phenomenon of the drag king scene. The author attempts at answering whether drag kings stand-ups are pure amusement, camp performance, or, possibly, an instance of political involvement. The first part of the article examines the theoretical contexts of the performance in question as well as previous research findings. The second part demonstrates the scope of author’s individual studies which included the application of the ethnographic method, together with content analysis techniques, and semi-structured interviewing. The data was collected in 4 interviews with Polish drag king representatives, and in 55 recordings of various performances. The results of the research suggest that political involvement is deeply rooted in drag king stand-ups. However, it is not the only category that can be applied to describe them.
Enforcing Heterosexuality: Adapting Lillian Hellman’s ‘The Children’s Hour’ for the screen
Authors: Glass Will
Published: September 2021

The Motion Picture Production Code of 1930 banned homosexuality from the screen. This paper uses two films as a case study of the Code's impact on Hollywood's depiction of homosexuality. Both These Three (1936) and The Children's Hour (1961) were adaptations of Lillian Hellman's play in which two single female teachers have their lives ruined by a lie that the women were lesbians. With the first the Code's impact was pervasive. The PCA dictated that the accusations of lesbianism be omitted. By the 1960s, the PCA was relaxing its ban so a film could be made that retained the play's lesbian content. This paper argues that the Production Code was Hollywood's means of enforcing heterosexuality and that, even in the era when the Code's influence was waning, the necessity of maintaining heterosexuality as society's norm still governed how movies (mis)represented the lives of queer people.

Awangarda seksualna
Authors: Leszkowicz Paweł
Published: September 2021

Homofobia ma różne oblicza. Manifestuje się w realnej przemocy i w nienawiści, ale i przybiera nobliwe oficjalne formy, wyłania się pod postacią prawa, kulturalnego obyczaju lub naukowej obiektywności. W twórczości artystycznej może pojawiać się jako negacja lub przemilczenie, jako deprecjonowanie lub nawoływanie do cenzury. Homofobia przede wszystkim jest jednak pewną stałą obecnością społeczną i kulturową. Jak zatem sobie z nią radzić, zanim będziemy mogli o niej zapomnieć? Jak ją wykorzystać przeciwko niej samej, jak jej represje przekształcić w kreacje? Poszukiwanie odpowiedzi na te dylematy doprowadziło mnie do sztuki i lekcji, jaką nam daje jej historia. Książka, która mnie ostatnio zainspirowała, stawia te problemy na ostrzu noża, prowokacyjnie i ambiwalentnie. Outlaw Representation. Censorship and Homosexuality in Twentieth-Century American Art czyli Przedstawienia wyjęte spod prawa. Cenzura i homoseksualizm w sztuce amerykańskiej XX wieku, taki tytuł nosi wydana w 2002 roku przez Oxford University Press, książka amerykańskiego historyka sztuki Richarda Meyera. Historia sztuki amerykańskiej, którą napisał Richard Meyer, jest historią zwycięzców, homoseksualnych artystów, którzy odnieśli sukces i którzy należą już do kanonu amerykańskiej kultury. Natomiast cenzura i homofobiczny zakaz są traktowane przez autora jako siły kreatywne, inspirujące artystów, pobudzające ich do wyszukanych strategii wizualnych i wystawienniczych Meyer skupia się na karierach i wybranych dziełach takich postaci, jak Paul Cadmus, Andy Warhol, Robert Mapplethorpe, David Wojnarowicz, Holly Hughes oraz grupy Gran Fury, związanej z aktywizmem wobec AIDS, którym poświęca poszczególne rozdziały. Wszyscy oni mają już swoje miejsce zarówno w historii sztuki, jak i historii homoseksualizmu. Książka Meyera nie odkrywa zatem nieznanych twórców, ofiar cenzury, ale analizuje dzieła tych, którzy potrafili wykorzystać represję i przetworzyć ją w artystyczny sukces. Ponadto analiza Meyera polega na tym, iż pokazuje, w jaki sposób zmaganie się z zakazem seksualnej ekspresji jest zapisane w strukturze dzieł. Autor nie dekoduje zatem homoseksualizmu z ukrytych kryptogramów, gdyż jest on na powierzchni twórczości wymienionych artystów, ale odsłania siłę jego obecności pomimo cenzuralnych nacisków i panującej w otaczającej kulturze homofobii. Jest to zatem historia nie tylko zwycięzców, ale i historia indywidualnej odwagi jednostki w obliczu systemu, z tego też powodu Outlaw Representation to książka do pewnego stopnia triumfalna, opowiadająca historię sławy, trwającej więcej niż warholowskie piętnaście minut, nie tylko pomimo, ale właśnie dzięki cenzurze i homoseksualizmowi.
Uniwersalizm i partykularyzm w polityce emancypacji – fałszywa alternatywa
Authors: Jarymowicz Tomasz
Published: September 2021

The article deals with the issue of universalism versus particularism and its implication for minority politics. It will be argued that without the problematization of the tension between universalism and particularism the emancipatory potential of minority politics is lost and remains only a declaration. The author begins with the critique of Richard Rorty's pragmatism which disregards the particularist content in every minority politics. Later the author moves on to present Judith Butler's stance towards universalism and he concludes with Ernesto Laclau's theory of agonist democracy where the problem of universalism and particularism is, in the author's view, best taken into account when minority politics is at stake.
„My się kochamy, jesteśmy parą gejów z pieskiem, a seksu nigdy nie uprawiamy”. Męskość i seksualność w perspektywie aktywistów ruchów queerowych w Polsce
Authors: Struzik Justyna
Published: September 2021

This article discusses the main characteristics of the politics of masculinity visible within Polish queer movements. In this paper I examine the way in which gay activists define and negotiate their identity and describe queer collective actions in reference to their gender dimension. The first part of the paper presents a summary of contemporary approaches towards masculinity and towards a gender perspective on social movements. In the second part, which is based on semi-structured interviews with queer activists, I draw on various attitudes of the respondents towards a greater visibility of gay identities, the presence of sexuality in the movements’ discourses and an internal differentiation of non-heteronormative masculinities.
Tradycyjna rola w nietradycyjnej rodzinie. Transnarodowa migracja polskich żon i matek – studium przypadku
Authors: Muszel Magdalena
Published: September 2021

Family gender roles and family relationships influence the lives of Polish transnational families to a great extent. Traditionally adopted gender roles connected with being a mother and wife largely shape the experience and attitudes of Polish female migrants in Ireland: starting with the decision about the migration, through family relations during the separation period, and ending up at the point of reunion. Attempts to continue to perform the traditional role of a mother and wife in the face of the transnational migration is an effort to preserve Polish women’s sense of identity as well as provisional power within their families.
Queer Heterotopias: Homonormativity and the Future of Queerness
Authors: Jones Angela
Published: September 2021

First, this article draws from Michel Foucault to examine the creation of what is conceptualized here as queer heterotopias. Queer heterotopias are material spaces where radical practices go unregulated. They are sites where actors, whether academics or activists, engage in what we might call a radical politics of subversion, where individuals attempt to dislocate the normative configurations of sex, gender, and sexuality through daily exploration and experimentation with crafting a queer identity. Second, this article, utilizing Gilles Deleuze analyzes the process of becoming queer. The ways in which queerness develops in everyday life must be seen less as a clearly-defined political program and more as a spiritual journey individuals embark on. This article explores the development of queer heterotopias, and the problematic way in which queerness is being made, re-made, and fixed by academics and well-meaning activists who would like to appropriate, qualify, and fix queer subjectivity in order to advance a rights-based political program. The current policing of queerness, by both heteronormative and homonormative logic works against the development of queer heterotopias.
(Trans)mężczyźni, (trans)kobiety i seksualność. O społecznym konstruowaniu seksualności w odniesieniu do osób transpłciowych
Authors: Kłonkowska Anna
Published: September 2021

The paper concerns sexual orientation of transgender people and expert discourse strategies of normativisation of sexuality of the mentioned group of people. The paper is based on qualitative analysis of transgender people’s statements concerning their sexual orientation. Basing on the assumptions of social constructionism, author of the paper tries to demonstrate that the common manner of presenting sex, gender and sexuality referring to the binary categories of description and classification (man/woman, heterosexuality/homosexuality, cisgenderism/transgenderism, etc.) is a construct of discourse based on the essentialist concept of sex, gender and sexuality. In accordance to the concept of the tool of power-knowledge (Foucault), this discourse legitimizes a definite idea of social order and supports definite strategies of normativization.
To Come: Queer Desire and Social Flesh
Authors: Sikora Tomasz
Published: September 2021

Artykuł "To, co nadchodzi: odmieńcze pożądanie i ciało społeczne" jest próbą przeformułowania idei społeczności (sociality) za pomocą aparatu pojęciowego zaproponowanego przez Deleuze'a/Guattariego, a zwłaszcza ich koncepcji pożądania jako podstawowej siły produkującej to, co społeczne. Pożądanie jest w artykule zdefiniowane jako odmieńcza tendencja do powstawania nowych formacji i podmiotowości w polu społecznym. Tej tendencji przeciwstawiony jest "popęd śmierci", który dąży do utrwalania (ossyfikacji) istniejących esencjalizujących się tożsamości, nabierających cech "przeznaczenia". W tym ujęciu odmieńczość byłaby samym procesem namnażania się różnicy, natomiast jednym z istotnych zadań teorii queer byłoby uważne obserwowanie tego, co dopiero "wyłania się" na horyzoncie praktyk społecznych. Nie odrzucając tego, co istnieje, queer skłania się w stronę tego, co nadchodzi. Traktując podejrzliwie wszelkie inwestycje w instytucjonalność i społeczną użyteczność, teoria queer powinna raczej skupiać się na tym, co (jeszcze) niespołeczne, co wirtualne, co niezaprzężone w rozliczne funkcjonalności organów/organizmów/organizacji. Deprywatyzacja / uspołecznienie pożądania, jego "de-edypalizacja", może być jednym ze sposobów wyjścia poza obecną konfigurację władzy, w której głównymi aktorami są indywidualistyczny i konsumpcjonistyczny neoliberalizm oraz autorytarny neokonserwatyzm. To, co społeczne, da się pomyśleć (za Hardtem i Negrim) jako niedający się okiełznać "cielesny" żywioł, w którym możliwe stają się nowe, nieprzewidziane połączenia i "asamblaże", nowe zbiorowości zespolone podług innych niż dotychczasowe parametrów przynależności. Umożliwiając nowe przepływy pożądania, queer destabilizuje każde rzekomo skończone, zamknięte i zunifikowane pole społeczne, zorganizowane w indywidualną tożsamość, w rodzinę, w społeczeństwo, w elektorat. Żadne takie "grodzenie" tego, co społeczne, nie jest nigdy do końca skuteczne: coś zawsze umyka - po to, aby mogło wyłonić się coś innego.
From there to Rehearsing Sex: A space of freedom among theory and the dead meandering to assist with resistance
Authors: Lambrinidis Christianna
Published: September 2021

On a rectangular table, four heads recollect their personal experiences of existence. In the absence of physical body no gender or sex differations exist. However, in depicting images of their existence the four heads recall relationships and emotions characterized by all the stereotypes of engendered relations. Submisal, obedience, resistance, are evident. The limits and power play of family and sex bondages are revealed. Through a constant state of sleep and/or death the heads speak with their eyes closed the truths of their selves. Pursuance of pleasure (achieved through sex) and desire of fulfillment motivates their every action and thought and allows to endure the pain that emerges from the lack of completeness. Language is the medium that gives meaning to an existential life, sets the space of one's freedom, constructs or deconstructs reason. "Rehearsing Sex" can be seen/heard as a paradigm of queer theory, where sexual identities and relations are being revised and reconstructed.
Ice nucleation activities of soot particles internally mixed with sulphuric acid at cirrus cloud conditions
Authors: Gao Kunfeng , Zhou Chong-Wen , Meier Eszter J. Barthazy , Kanji Zamin A.
Published: September 2021

Abstract. Soot particles are important candidates for ice nucleating particles (INPs) in cirrus cloud formation which is known to exert a warming effect on climate. Bare soot particles, generally hydrophobic and fractal, mainly exist near emission sources. Coated or internally mixed soot particles are more abundant in the atmosphere and have a higher probability to impact cloud formation and climate. However, the ice nucleation ability of coated soot particles is not as well understood as that of freshly produced soot particles. In this study, two samples, a propane (C3H8) flame soot and a commercial carbon black were coated with varying wt % of sulphuric acid (H2SO4). The ratio of coating material mass to the mass of bare soot particle was controlled and progressively increased from less than 5 wt % to over 100 wt %. Both bare and coated soot particle ice nucleation activities were investigated with a continuous flow diffusion chamber operated at mixed-phase and cirrus cloud conditions. The mobility size and mass distribution of size selected soot particles with/without H2SO4 coating were measured by a scanning mobility particle sizer (SMPS) and a centrifugal particle mass analyser (CPMA) running in parallel. The mixing state and morphology of soot particles were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). In addition, the evidence for the presence of H2SO4 on coated soot particle surface is shown by Energy Dispersive X-ray spectroscopy (EDX). Our study demonstrates that H2SO4 coatings suppress the ice nucleation activity of soot particles to varying degrees depending on the coating thickness, but in a non-linear fashion. Thin coatings causing pore filling in the soot-aggregate inhibits pore condensation and freezing (PCF). Thick coatings promote particle ice activation via droplet homogeneous freezing. Overall, our findings reveal that H2SO4 coatings will suppress soot particle ice nucleation abilities in the cirrus cloud regime, having implications for the fate of soot particles with respect to cloud formation in the upper troposphere.

Abstract. The Amazon rain forest plays a major role in global hydrological
cycling, and biogenic aerosols are likely to influence the formation of
clouds and precipitation. Information about the sources and altitude
profiles of primary biological aerosol particles, however, is sparse. We
used fluorescence in situ hybridization (FISH), a molecular biological staining
technique largely unexplored in aerosol research, to investigate the sources
and spatiotemporal distribution of Amazonian bioaerosols on the domain level. We
found wet season bioaerosol number concentrations in the range of 1–5 × 105 m−3 accounting for > 70 % of the
coarse mode aerosol. Eukaryotic and bacterial particles predominated, with
fractions of ∼ 56 % and ∼ 26 % of the
intact airborne cells. Archaea occurred at very low concentrations. Vertical
profiles exhibit a steep decrease in bioaerosol numbers from the understory
to 325 m height on the Amazon Tall Tower Observatory (ATTO), with a stronger
decrease in Eukarya compared to Bacteria. Considering earlier
investigations, our results can be regarded as representative for
near-pristine Amazonian wet season conditions. The observed concentrations
and profiles provide new insights into the sources and dispersion of
different types of Amazonian bioaerosols as a solid basis for model studies
on biosphere–atmosphere interactions such as bioprecipitation cycling.
An Ensemble-Based Statistical Methodology to Detect Differences in Weather and Climate Model Executables
Authors: Zeman Christian , Schär Christoph
Published: September 2021

Abstract. Since their first operational application in the 1950s, atmospheric numerical models have become essential tools in weather and climate prediction. As such, they are subject to continuous changes, thanks to advances in computer systems, numerical methods, more and better observations, and the ever increasing knowledge about the atmosphere of Earth. Many of the changes in today’s models relate to seemingly unsuspicious modifications, associated with minor code rearrangements, changes in hardware infrastructure, or software updates. Such changes are not supposed to significantly affect the model. However, this is difficult to verify, because our atmosphere is a chaotic system, where even a tiny change can have a big impact on individual simulations. Overall this represents a serious challenge to a consistent model development and maintenance framework. Here we propose a new methodology for quantifying and verifying the impacts of minor atmospheric model changes, or its underlying hardware/software system, by using a set of simulations with slightly different initial conditions in combination with a statistical hypothesis test. The methodology can assess effects of model changes on almost any output variable over time, and can also be used with different underlying statistical hypothesis tests. We present first applications of the methodology with a regional weather and climate model, including the verification of a major system update of the underlying supercomputer. While providing very robust results, the methodology shows a great sensitivity even to tiny changes. Results show that changes are often only detectable during the first hours, which suggests that short-term simulations (days to months) are best suited for the methodology, even when addressing long-term climate simulations. We also show that the choice of the underlying statistical hypothesis test is not of importance and that the methodology already works well for coarse resolutions, making it computationally inexpensive and therefore an ideal candidate for automated testing.
The impact of microplastic weathering on interactions with the soil environment: a review
Authors: Büks Frederick , Kaupenjohann Martin
Published: September 2021

Abstract. Recent studies have reported the influence of microplastic on soil quality parameters. Mass concentrations of plastic particles as found in highly contaminated soils were shown to weaken the soil structure by reducing the proportion of water stable aggregates (WSA). In addition, parts of the edaphon are adversely affected by mainly the < 100 µm microplastic fraction. The specific interaction of soil microplastic with other particulate organic matter (POM) and the mineral phase during the formation of soil aggregates as well as the adverse effects of especially the small-sized fraction, which has low weight but high specific surface area, justify a focus on surface properties of the soil microplastic and their alteration during the plastic life cycle. Exposed to UV radiation, juvenile plastic undergoes photochemical weathering with embrittlement and the formation of surface charge. When plastic particles enter the soil environment, a second step takes place, that includes biogeochemical weathering with enzymes, biotic and abiotic acids, oxidants as well as bioturbation and feeding of soil fauna. This work integrates recent findings on the effects of microplastic on soil structure and biota, the genesis of its surface characteristics and discusses how to reproduce them to conduct laboratory experiments with close-to-nature designer microplastic.

A country is prosperous if it has efficient development programs. Human capital contains resources like education, health, training, skills etc. For economic progress these qualities are very vital. Basic objective of this research is to explain the impact of human capital on growth and development of economics sector of the Pakistan. Because today in the developing countries, human development and growth has becomes the burning issues. To analyse the association between human capital and economic growth, used GDP as a dependent variable. This study further use Human development index as independent variable. Proxy of human development index consist of education index, health, fertility, infant mortality, life expectancy and sanitation. Our focus will be more on the education. Time series data for the years 1990-2019 were used. ARDL model was used by incorporating the human capital formation with other explanatory variables. The findings shows that the human capital has positive and significant impact on growth and the negative influence on the population and infant mortality rate.
THE ORIGIN OF MASS
Authors: WILCZEK Frank
Published: September 2021

Everyday work at the frontiers of modern physics usually involves complex concepts and extreme conditions. We speak of quantum fields, entanglement, or supersymmetry, and analyze the ridiculously small or conceptualize the incomprehensibly large. Just as Willie Sutton famously explained that he robbed banks because “that’s where the money is,” so we do these things because “that’s where the Unknown is.” It is an amazing and delightful fact, however, that occasionally this sophisticated work gives answers to childlike questions about familiar things. Here I’d like to describe how myown work on subnuclear forces, the world of quarks and gluons, casts brilliant new light on one such child-like question: What is the origin of mass?

The presence of metals in the environment has been linked to the evolutionary processes of man and nature. Its influence on biochemical mechanisms in organisms has been proven by numerous studies in recent years. However, due to the influences of anthropogenic activities, the presence of important amounts of metals has been found mainly in the regions close to the metal manufacturing industries, causing a local geochemical alteration, aggravated by natural factors such as rainfall, contaminating all levels of the chain trophic region.

Most people agree with Arthur Schopenhauer, the great German philosopher who said: “Health is not everything; however, without health, everything is nothing ”. When we ask ourselves about our desires and hopes for the future, health always comes first. But what is health really? Ideally, it is a total state of physical, spiritual and social well-being. For the individual, health means not being sick, but being trained, fit and in a good mood.

Spinel oxides with the composition ZnCo2O4 and ZnCo2O4:Eu3+ have been synthesized by the Pechini method and characterized by X-ray diffraction, infrared spectroscopy, thermal analysis and scanning electron microscopy. IR spectroscopy revealed the presence of n1 and n2 bands, typical of spinel structures. The formation of monophase cubic spinel structure was confirmed by X-ray diffraction patterns. Extra lines corresponding to other phase has been observed in the powders calcined at 900 ºC. The results showed the extremely lower synthesis temperature than those presents in conventional methods.
DYES: COLORS AND THEIR FASCINATION IN SOCIETY
Authors: GOLDANI Eduardo
Published: September 2021

Color plays an essential role in our lives, but goes unnoticed most of the time. Most people have the ability to notice colors and ever since the criation of civilization man has been trying to reproduce the colors of nature for functional purposes as well as merely for looks. Dyes are materials normaly applied to solution and adhere themselves to a substract that can be fabric, paper, hair, leather and other materials. Idealy, dyes should be stable to light and to cleaning precesses and should also present uniform adherence to fiber throughout the substract. In other words dyes are determined organic compounds that aside from having the capacity of seletive absorption of light, acquiring intense coloration they are also capable of adhering to fibers and impossible to be removed by water. Many natural or syntetic substances used as fiber textil dyes belong to the class of the heterocyclic compounds.
THE RISKS OF MOBILE TELEPHONY AND THE PRECAUTIONARY PRINCIPLE
Authors: SALLES A.A. de , FERNÁNDEZ C.R.
Published: September 2021

There has been a dramatic increase in the use of mobile phone technology in the last decades, with widespread benefits in many professional and private activities. In parallel with this, the concern regarding the possibility of adverse health effects due to the absorption of electromagnetic fields by humans also increased. For several years, many research groups in different countries were developing research projects on these subjects in the areas of medicine, biophysics, engineering, etc. Also, the World Health Organization (WHO) has coordinate efforts including many countries to access the existing scientific evidence of harmful health effects of non ionizing radiation (NIR) emitted from different communication equipment, such as the mobile phones and their base stations, with special emphasis to the non-thermal effects. In principle, the base stations radiate more energy. However, their antennas are usually located on the top of elevated towers (or masts) and the radiated energy is mainly concentrated in the horizontal direction. Therefore people are usually far from these antennas, and also in directions reasonably apart from those of maximum radiation. Because the conventional monopole (or whip) antennas being used now in mobile phones typically show a circular radiation pattern in the horizontal plane, they may radiate substantial levels of energy in almost all directions, very close to the body and during considerable time. It is observed that when they are operated very close to the user’s head (e.g., 2,5 cm or less) , most of energy is absorbed in the head tissues (such as the bone, the brain, eye, etc), and less energy is radiated to the nearest base station. This situation is undesirable since quality of communication is worse, and the Specific Absorption Rate (SAR) in the user’s head and the battery drain are increased.

FORMALDEHYDE AND ACETALDEHYDE EMISSIONS FROM BIODIESEL / DIESEL MIXTURES
Authors: CORRÊA Sérgio Machado , ARBILLA Graciela
Published: September 2021

With the approval in January 2005 of Law 11,097, the addition of 2% biodiesel to diesel in the Brazilian energy matrix is ??authorized. As a consequence, several segments have started studies for the production of biodiesel from oilseeds, such as castor, soy, cotton, sunflower, cotton among others, as well as from residual fatty materials such as frying oils. It has been identified, by several studies, that biodiesel emits less carbon dioxide, sulfur oxides and particulate matter. However, some classes of pollutants, such as volatile organic compounds (VOCs), still need studies. The emissions of these pollutants cannot be identified with the online equipment used by the environmental agencies, as they only provide the total amount of the compounds. This work carried out an evaluation of a sub-class of VOCs, carbonyls. There are few references in the literature about the emission of these compounds, which are highly toxic and lead to the formation of photochemical oxidants such as ozon. Two 6-cylinder diesel engines, typical of the urban bus fleet, were used, which were tested with different proportions of biodiesel: 2, 5, 10 and 20%, respectively B2, B5, B10 and B20, as well as with pure diesel (D ) To compare. For each mixture, 5 samplings were performed and the results indicated an increase in the concentration of formaldehyde according to the increase in biodiesel in diesel, as well as in the levels of acetaldehyde, to a lesser extent. These results can be attributed to the presence of oxygen atoms in the biodiesel molecule.

Published: September 2021

Data for speciated volatile organic compounds (VOC) evaluated in Santos-Dumont Airport and Antonio Carlos Jobim International Airport in Rio de Janeiro, Brazil, are reported. VOC were evaluated by gas chromatography with flame ionization detection (GC – FID) and mass spectrometry (GC – MS), following the U.S. EPA TO – 15 methodology. At Santos-Dumont Airport were quantified 1376 µg m-3 of VOCs 10 m from runway, 408 µg m-3 inside the airport building, and 116 µg m-3 outside the airport area. At the taxiway area of the International Airport a total of 190 µg m-3 of VOC were quantified. Toluene, the most abundant compound near the Santos-Dumont Airport runway, was obtained in a non-significative concentration outside the airport area. This fact suggests that this area is not noticeably impacted by air traffic. A computational model was developed using the OZIPR program and the SAPRC mechanism. Calculated ozone concentrations are higher than values for downtown area of Rio de Janeiro city. Simulated results show that, for the runway in Santos-Dumont Airport, olefins and aromatics contribute in 57% and 15%, respectively, to ozone formation, toluene being the major contributor. Cis-2-butene is the most reactive species regarding OH reaction.

Published: September 2021

The great growth of the industrial activity verified in the last decades has been taking to the production of a great amount of synthetic products, many of these, toxics and cancerous, that they can reach the fluvial system, atmospheric or soil. To maintain the industrial discharges inside of the established limits for the environmental control, two alternatives exist: (a) development and use of new processes of the industrial residues and (b) adaptation and optimization of the processes of industrial production, aiming to reduce the residues generation. The interest in studies involving the clays, as well as the zeolit, and the silicals, are increasing sensibly in the last years, as much of the academic point of view of applications in technology. The present paper article discusses the ways to evaluate the characteristics and adsorption/dessorption mechanism in the removal of organic pollutant liquids and gaseous of Brazilian clays, with the intention of reaching a larger understanding of the involved processes, as well as to establish a base for use of these materials in the treatment of industrial effluents. The experimental methods which orgonoclays is prepared from the mixture of alkylammonium salts with different chain sizes and the clay, in the complete absence of solvents (reactions or interactions solid-solid) showed that the variations in the inter-basal distances of the clay containing the ions incorporate alkylammonium to the clay located in the interlamellar area of the particles, and as larger the spacing inter-basal of the orgonoclays (due to the incorporation of ions alkylammonium with different chain sizes), the penetration of the organic molecules is more favored.

The synthesis by combustion reaction is distinguished as one alternate technique for powders preparation with high pureness degree , nanometric size of particles, and low cost. Thus, this work had as objective the synthesis and characterization of Ni0,5-xCuxZn0,5FeO4 ferrites powders with x=0,0; 0,1; 0,2; 0,3; 0,4 and 0,5 mol prepared by combustion reaction. The influence of the simultaneous substitution of Ni for Cu in the synthesis and the final characteristics of the powders also was investigated. The powders were characterized by BET, DRX, MEV, and sedimentation. The results showed that the combustion reaction synthesis is an adequate process to get crystalline powders of Ni-Cu-Zn ferrite with cristaline sizes between 30,0 - 47,5 nm. The increase of Cu addition lead to a slight increase of the cristalite size due to an increase in the time and temperature of combustion flame.

Authors: VASCONCELOS Adriana Palmeiro , CORRÊA Sérgio Machado
Published: September 2021

The mixing of biodiesel and petroleum diesel is being widely used as an attempt to reduce the emissions of sulfur compounds. These compounds are responsible for pollution, causing several diseases, like some breath problems. Sulfur compounds cause car catalyst poisoning and deactivation of processing, contributing to undesirable emissions of other toxic compounds. The goal of this work was to identify sulfur compounds in diesel and in some biodiesel mixtures of different sources. Gas chromatography system coupled with FID (flame ionization detector) was the methodology initially employed, for adjustment of the operational conditions, since FID is a low selectivity detector capable of identifying sulfur compounds and the majority of hydrocarbons. After that, a selective detector for sulfur compounds was employed (SCD - sulfur chemiluminescence detector). The results showed that sulfur compounds decreased proportionally with the addition of biodiesel.

This study aimed to evaluate the ability to remove an ion Cr (III) in synthetic wastewater using a Brazilian clay. We evaluated the influence of the concentration of cation and anion effect on the ability of removal of chromium ions in effluent inorganic synthetic clay for montmorillonite (F-II) Fulmont provided by the industry. The clay was characterized by X-ray diffraction and chemical analysis. The tests were performed by removal of two different methods: in batch reactor and filtration in a column of clay. Tests were conducted at different pH `s (2-10), the mass of clay and solution of chromium nitrate (III) used in each test was 2g and 25 ml respectively. The efficiency of removal was determined by atomic absorption analysis of the supernatants. Preliminary results showed the efficiency of removal of chromium ions by the Brazilian clay. It was observed that the concentration of the solution, the experimental procedure and the presence of anions influenced the process of exchange, with the best results when used dilute solutions in the presence of nitrate ion and technology in filtration column resulting in removal of up to 100% of chromium (III).

Published: September 2021

In this work the process of co-pyrolysis of polyethylene plastic residue was carried through with petroleum, in a temperature of 550°C. First, the polyethylene samples and petroleum had been submitted the thermal co-pyrolysis in inert atmosphere. Later they had been evaluated the efficiency of the process with variation of the amount of polyethylene residue added to the petroleum. The generated pyrolytic liquids had been characterized by modified gaseous chromatography, with the objective to evaluate the generation of fractions in the band of the distillation of diesel. It can be observed that the increase of the amount of PE in the half reactional favors the reduction of the income of pyrolytic liquid and the increase of the amount of generate solid. The results show that plastic residue co-pyrolysys is a potential method for chemical recycling of plastic products.
