Racismo, gênero e mito atualizado no arco-íris de "Ponciá Vicêncio"
Authors: Passos Leandro , Nigro Cláudia Maria Ceneviva
Published: November 2019

Neste artigo, propomos a leitura do romance Ponciá Vicêncio (2003) a partir da simbologia do que por ora denominamos mito atualizado do arco-íris. Na obra em questão, apontamos o modo como os mitos bantu, iorubá, nórdico, romeno, irlandês, greco-romano, judaico, bem como a simbologia do arco-íris das bandeiras whipala andina e do movimento LGBTQI+, podem ser vistos na trama poética da narrativa de Conceição Evaristo. Ribeiro (2018), Daibert (2015), Dionísio (2013) e Ford (1999) são alguns dos autores que fundamentam a perspectiva presente no texto analisado. Justificamos este estudo porque, sabedora do conhecimento ancestral africano e conhecedora das culturas do mundo que a circundam, Conceição Evaristo de Brito é porto seguro no debate do feminismo negro. Escritora responsável pela abertura de oportunidades para as mulheres negras na literatura, Conceição fez o seu percurso na raça. Considerada internacionalmente e nacionalmente como detentora de uma escrita cuidada e potente, e também como Yabá querida e respeitada na comunidade negra, Evaristo é leitura recomendada e obrigatória a todas e todos.
Andorinhas e águas – lembranças: elementos de resistência feminina em “Quem manda aqui”, de Paulina Chiziane, e “Sabela”, de Conceição Evaristo
Authors: Pimenta Júnior Pedro Borges
Published: November 2019

O presente artigo trata da utilização, em textos produzidos por escritoras negras, de elementos naturais que remetem à resistência das mulheres às realidades excludentes e à capacidade delas para atuar na construção e transformação da sociedade. Para tanto, serão analisados o conto Quem manda aqui?, do livro As andorinhas (2013a), escrito pela moçambicana Paulina Chiziane, e Sabela, da escritora brasileira Conceição Evaristo, novela publicada no livro Histórias de leves enganos e parecenças (2016). O estudo aqui proposto põe em evidência a simbologia de resistência feminina e negra que as andorinhas de Chiziane e as águas-lembranças de Conceição Evaristo evocam, ajudando a compreender o projeto literário de ambas. Nesse sentido, a leitura das obras e a revisão de bibliografia que se realizou foram orientadas pelos estudos de Maria Nazareth Fonseca (2014), Francisco Noa (2019), Pierre Bourdieu (2012), Assunção Silva (2016), Ana Mafalda Leite (2003), Carmem Lúcia Tindó Secco e Cláudia Medeiros (2014), Mircea Eliade (1979) e Alfredo Bosi (1977).
Organic tracers of fine aerosol particles in central Alaska: summertime composition and sources
Authors: Deshmukh Dhananjay Kumar , Haque M. Mozammel , Kim Yongwon , Kawamura Kimitaka
Published: November 2019

Abstract. PM2.5 aerosols were collected at Fairbanks (64.51∘ N and
147.51∘ W) in central Alaska during the summer of 2009 and
analyzed for organic tracer compounds using a gas chromatograph–mass
spectrometer. The organic compounds were grouped into 14 classes based
on their functional groups and sources. Concentrations of the total organics
measured ranged from 113 to 1664 ng m−3 (avg 535 ng m−3).
Anhydrosugars (avg 186 ng m−3) and n-alkanoic acids (avg 185 ng m−3) were 2 major classes among the 14 compound classes. The similar
temporal trends and strong positive correlations among anhydrosugars and
n-alkanoic acids demonstrated that biomass burning (BB) is the major source
of organic aerosols (OAs) in central Alaska. The dominance of higher
molecular weight n-alkanoic acids over lower molecular weight homologs and their carbon preference index (5.6–9.8) confirmed that they were mostly
emitted from plant waxes during BB in central Alaska. The mass concentration
ratios of levoglucosan to mannosan denoted that softwood is the main biomass
burned. The rainfall event distinctly enhanced the levels of mannitol and
arabitol due to the growth of fungi and active discharge of fungal spores in
the subarctic region. Molecular compositions of biogenic secondary organic
aerosol (BSOA) tracers inferred that isoprene is a crucial precursor of BSOA
over central Alaska. Our results suggest forest fires and plant emissions to
be the crucial factors controlling the levels and molecular composition of
OAs in central Alaska. We propose that PM2.5 laden with OAs derived in
central Alaska may significantly impact the air quality and climate in
the Arctic via long-range atmospheric transport.

Abstract. Despite the high abundance of secondary aerosols in the atmosphere, their formation mechanisms remain poorly understood. In this study, MCM/CAPRAM mechanism is used to investigate the multiphase formation and processing of secondary aerosol constituents during the advection of air masses towards the measurement site of Mt. Tai in North China. Trajectories with and without chemical cloud interaction are modeled. Modeled radical and non-radical concentrations demonstrate that the summit of Mt. Tai, with an altitude of ∼1.5 km a.m.s.l., is characterized by a sub-urban oxidants budget. The modeled maximum gas-phase concentrations of OH radical are 3.2 × 106 molecules cm−3 and 3.5 × 106 molecules cm−3 in simulations with and without cloud passages in the air parcel, respectively. Different to previous studies at Mt. Tai, this study has modeled chemical formation processes of secondary aerosol constituents under day vs. night and cloud vs. non-cloud cases along the trajectories to Mt. Tai in detail. The model studies show that sulfate is mainly produced in simulations where the air parcel is influenced by cloud chemistry. Under the simulated conditions, the aqueous reaction of HSO3− with H2O2 is the major contributor to sulfate formation, contributing 67 % and 60 % in the simulations with cloud and non-cloud passages, respectively. The modeled nitrate formation is higher at nighttime than at daytime. The major pathway is aqueous-phase N2O5 hydrolysis, with a contribution of 72 % when cloud passages are considered and 70 % when not. Secondary organic aerosol (SOA) compounds, e.g. glyoxylic, oxalic, pyruvic and malonic acid, are found to be mostly produced from the aqueous oxidations of hydrated glyoxal, hydrated glyoxylic acid, nitro 2-oxopropanoate and hydrated 3-oxopropanoic acid, respectively. Sensitivity studies reveal that gaseous VOC emissions have a huge impact on the concentrations of modeled secondary aerosol compounds. Increasing the VOC emissions by a factor of two leads to linearly increased concentrations of the corresponding SOA compounds. Studies using the relative incremental reactivity (RIR) method have identified isoprene, 1,3-butadiene and toluene as the key precursors for glyoxylic and oxalic acid, but only isoprene is found to be a key precursor for pyruvic acid. Additionally, the model investigations demonstrate that an increased aerosol partitioning of glyoxal can play an important role in the aqueous-phase formation of glyoxylic and oxalic acid. Overall, the present study is the first that provides more detailed insights in the formation pathways of secondary aerosol constituents at Mt. Tai and clearly emphasizes the importance of aqueous-phase chemical processes on the production of multifunctional carboxylic acids.
Retrieval of cloud properties from spectral zenith radiances observed by sky radiometers

Published: November 2019

Abstract. An optimal estimation algorithm to retrieve the cloud optical depth
(COD) and cloud particle effective radius (CER) from spectral zenith
radiances observed by narrow field-of-view (FOV) ground-based sky
radiometers was developed. To further address the filter degradation problem
while analyzing long-term observation data, an on-site calibration procedure
is proposed, which has good accuracy compared with the standard calibration
transfer method. An error evaluation study conducted by assuming errors in
observed transmittances and ancillary data for water vapor concentration and
surface albedo suggests that the errors in input data affect retrieved CER
more than COD. Except for some narrow domains that fall within a COD of < 15, the retrieval errors are small for both COD and CER. The retrieved cloud
properties reproduce the broadband radiances observed by a narrow FOV
radiometer more precisely than broadband irradiances observed by a wide-FOV
pyranometer, justifying the quality of the retrieved product (at least of COD)
and indicating the important effect of the instrument FOV in cloud remote
sensing. Furthermore, CODs (CERs) from sky radiometer and satellite
observations show good (poor) agreement.
Investigation of the behavior of the atmospheric dynamics during occurrences of the ozone hole's secondary effect in southern Brazil
Authors: Bittencourt Gabriela Dornelles , Pinheiro Damaris Kirsch , Bageston José Valentin , Bencherif Hassan , Steffenel Luis Angelo , Vaz Peres Lucas
Published: November 2019

Abstract. The Antarctic ozone hole (AOH) directly influences the Antarctic
region, where its levels can reach values below 220 DU. The temporary
depletion of ozone in Antarctica generally occurs between the beginning and
middle of August, during the austral spring, and extends to November, when a
temporary reduction in ozone content is observed in a large region over the
Antarctic continent. However, masses of ozone-depleted air can break away
from the ozone hole and reach mid-latitude regions in a phenomenon known
as the secondary effect of the Antarctic ozone hole. The objective of this
paper is to show how atmospheric dynamics behave during the occurrence of
this type of event, especially in mid-latitude regions, such as southern
Brazil, over a 12-year observation period. For the analysis and
identification of the events of influence of the AOH on the southern region
of Brazil, data from the total ozone column were used from ground-based and
satellite experiments, the Brewer Spectrophotometer (MkIII no. 167), and the
Ozone Monitoring Instrument (OMI) on the Aura satellite. For the analysis of
the stratospheric and tropospheric fields, the ECMWF reanalysis products
were used. Thus, 37 events of influence of the AOH that reached the southern
region of Brazil were identified for the study period (2006–2017), where the
events showed that in approximately 70 % of the cases they occurred after
the passage of frontal systems and/or atmospheric blocks over southern
Brazil. In addition, the statistical analysis showed a strong influence of
the jet stream on mid-latitude regions during the events. Among the 37
identified events, 92 % occurred in the presence of the subtropical and/or
polar jet stream over the region of study, possibly explaining the exchange
of air masses of ozone deficient in the upper troposphere–lower
stratosphere (UT–LS) region.
A weighting scheme to incorporate large ensembles in multi-model ensemble projections
Authors: Merrifield Anna Louise , Brunner Lukas , Lorenz Ruth , Knutti Reto
Published: November 2019

Abstract. Multi-model ensembles can be used to estimate uncertainty in projections of regional climate, but this uncertainty often depends on the constituents of the ensemble. The dependence of uncertainty on ensemble composition is clear when single model initial condition large ensembles (SMILEs) are included within a multi-model ensemble. SMILEs introduce new information into a multi-model ensemble by representing region-scale internal variability, but also introduce redundant information, by virtue of a single model being represented by 50–100 outcomes. To preserve the contribution of internal variability and ensure redundancy does not overwhelm uncertainty estimates, a weighting approach is used to incorporate 50-members of the Community Earth System Model (CESM1.2.2), 50-members of the Canadian Earth System Model (CanESM2), and 100-members of the MPI Grand Ensemble (MPI-GE) into an 88-member Coupled Model Intercomparison Project Phase 5 (CMIP5) multi-model ensemble. The weight assigned to each multi-model ensemble member is based on the member's ability to reproduce observed climate (performance) and scaled by a measure of redundancy (dependence). Surface air temperature (SAT) and sea level pressure (SLP) diagnostics are used to determine the weights, and relationships between present and future diagnostic behavior are discussed. A new diagnostic, estimated forced trend, is proposed to replace a diagnostic with no clear emergent relationship, 50-year regional SAT trend. The influence of the weighting is assessed in estimates of Northern European winter and Mediterranean summer end-of-century warming in the CMIP5 and combined SMILE-CMIP5 multi-model ensembles. The weighting is shown to recover uncertainty obscured by SMILE redundancy, notably in Mediterranean summer. For each SMILE, the independence weight of each ensemble member as a function of the number of SMILE members included in the CMIP5 ensemble is assessed. The independence weight increases linearly with added members with a slope that depends on SMILE, region, and season. Finally, it is shown that the weighting method can be used to guide SMILE member selection if a subsetted ensemble with one member per model is sought. The weight a SMILE receives within a subsetted ensemble depends on which member is used to represent it, reinforcing the advantage of weighting and incorporating all initial condition ensemble members in multi-model ensembles.
The human side of geoscientists: comparing geoscientists' and non-geoscientists' cognitive and affective responses to geology
Authors: Lacchia Anthea , Schuitema Geertje , McAuliffe Fergus
Published: November 2019

Abstract. Geoscientists and non-geoscientists often struggle to communicate with each other. In this paper we aim to understand how geoscientists and non-geoscientists perceive geological concepts and processes, that is, how they think (cognitive responses) and feel (affective responses) about them. To this effect, using a mixed-methods approach, we compare mental models – people's representation of a phenomenon – of the subsurface, mining/quarrying, drilling, and flooding between geoscientists (n = 24) and non-geoscientists (n = 38). We identify four dominant themes which underlie their mental models: (1) degree of knowledge and familiarity, (2) beliefs about human interactions, (3) affective beliefs, and (4) beliefs about perceived impact of the processes. While the mental models of non-geoscientists focus more on the perceived negative environmental and economic impacts of geoscience, those of geoscientists focus more on human interactions. We argue that mental models are the result of beliefs, including both cognitive and affective components, and that both need to be acknowledged for effective dialogue between the two groups to take place.
Anatomy of the Privatization of State-Owned Enterprises (SOEs) in Ghana: Implication for Policy and Accountability
Authors: Danso Eugene
Published: November 2019

With the administrative and operational functions of State-Owned Enterprises (SOEs) becoming increasingly complex and sophisticated among developing countries by the 1980s, privatization was recommended by the IMF/World Bank as a remedy to these institutional deficiencies . This is contingent on the neoclassical debate that private ownership rather than public ownership of management and operations of SOEs results in prudent policy process and accountability. Therefore, this study sought to assess the validity of this assertion by employing the Principal-Agent theory in assessing the level of accountability between the citizens (principal) and the government (agent) during private ownership of service delivery. As a qualitative study, this paper adopts unobtrusive content analysis of an empirical study of the privatization of Ghana Water Company Limited (GWCL). The government (agent) under the Principal-Agent theory is to ensure that the private operator, Aqua Vitens Rand Limited (AVRL) respects the terms of divestiture, while upholding the principles of accountability. However, the findings of the study suggest that the failure of government (agent) to uphold core accountability mechanisms such as transparency, accessibility to information, sense of ownership, responsiveness, and conformity to established monitoring and evaluation measures, contributed to the inability to achieve key performance targets, leading to the unsuccessful policy outcome of the privatization contract. This paper, therefore, argues that the failure to adopt accountability mechanisms in the divestiture of SOEs will inevitably compromise administrative policy outcomes.
Management and Control of Classroom for Effective Teaching-Learning Process in Tertiary Institutions: Policy Implications
Authors: Alabi Amos Oyetunde
Published: November 2019

The paper examines the importance of management and control of the classroom for effective teaching-learning process in tertiary institutions. Classroom or lecture room is one of the most important facilities in tertiary institutions being the pedagogical home of instruction. Lecture room may be physical as in the case of a four-wall room and it may be abstract as in the case of on-line teaching.Classroom management and control are affected by psychosocial, physical and teaching methods. Each of those factors plays a very significant role in the management and control of class/lecture room for effective teaching-learning process. Each of them can make or mar the teaching-learning process depending on how the lecturer understands and handles them.The paper, however, recommends some steps to be taken by lecturers to manage and control the classroom for effective teaching-learning process. Some of these are; the teacher being a model to the students should endeavour to know the students very well and by names, build good, cordial and lively relationship with the learners helps students to develop positive confidence in themselves, prepare well for the lectures, create conducive learning atmosphere in the lecture room and set some rules, among others.The paper considers some policy implications of management and control of the classroom for effective teaching and learning processes on the proprietor, management, staff and students in a tertiary institution.

Ao longo da literatura psicanalítica, observamos casos em que o analista encontra dificuldade ao lidar com certos tipos de pacientes, estes que apresentam pouca melhora sem um manejo especial. Baseando-se nisso, consideramos que Donald Winnicott e Wilhelm Reich trazem importantes contribuições para o tema, principalmente quando introduzem os conceitos de falso self e couraça. Nosso objetivo, portanto, delineia-se em estabelecer um breve diálogo entre estes conceitos, destacando algumas aproximações e distanciamentos. A metodologia de pesquisa se faz por meio do levantamento bibliográfico, sendo de natureza qualitativa e histórica. Ao final do trabalho, concluímos que os conceitos de couraça e falso self mais se aproximam do que se distanciam, na medida em que dizem respeito ao bloqueio emocional, da motilidade, da agressividade e da espontaneidade.

Published: November 2019

O objetivo deste ensaio teórico é sugerir diretrizes para a atuação de psicólogos no Conselho Tutelar (CT). Sua escrita encontra-se motivada pelo entendimento de que a inserção da psicologia no CT ocorre recorrentemente por meio de práticas que desconfiguram o CT como órgão autônomo de função político-administrativa. Os psicólogos inseridos no CT não devem, assim, se ocupar de serviços periciais e socioassistenciais ausentes ou precários no município, mas exercer funções que vão subsidiar as ações executadas pelos conselheiros tutelares. São apresentadas três possíveis atribuições nesses contextos: 1) capacitação e formação continuada a conselheiros tutelares; 2) supervisão técnica à delegação de medidas protetivas e encaminhamentos jurídicos; e 3) apoio técnico às atividades de caráter preventivo, de fiscalização e de cobrança. Sugere-se que a implementação de equipes multidisciplinares destinadas a assessorar o CT em suas funções deva ser regulamentada em nível federal.

Liberal Democracy and the Judeo-Christian Tradition

Liberal Democracy and the Judeo-Christian Tradition

Increasingly often, it is stated that the universal values underpinning Western liberal democracies are a product of a ‘Judeo-Christian’ tradition. This article explores the legitimacy of this claim from the perspective of liberal-democratic theory. It argues that state-endorsed claims about the historical roots of liberal-democratic values are problematic (1) if they are promoted as though they are above democratic scrutiny and (2) if they insinuate that citizens who belong to a particular (majority) culture remain the ‘cultural owners’ of the core values underpinning the state. More pragmatically, the paper suggests that the claim carries the risk of failing to facilitate all citizens becoming or remaining committed to nurturing fundamental rights and a shared society based on norms of democratic equality.

The study established statistically significant differences and trends in the scope of differentiation in aggressive tendencies in the studied groups. Based on the research the author presents practical applications in the form of prophylactic recommendations, concerning the use of educational measures by courts with respect to juveniles who commit punishable acts using violence.
The long-term effects of childhood neglect or abuse. Implications for child and family services in the UK
Authors: BIFULCO ANTONIA
Published: November 2019

Childhood neglect or abuse is damaging, with lifelong impacts on functioning, clinical and physical health. It can also transmit risk to the next generation. Child abuse is related to social deprivation, a source of family breakup, common in families under stress and is associated with other social ills such as domestic violence, and parental mental health problems. It is therefore costly to society financially, emotionally and in terms of family wellbeing. It is increasingly seen as a major public health issue given its wide prevalence. Contemporary issues in the UK concern not only ongoing neglect or abuse of children, but also the impact of historical abuse, a psychological burden to a significant number of adults. Often untreated, and occurring before adequate child protection policies were in place, the impacts of historical abuse is an ongoing concern both for health and social care services. This paper will describe the Childhood Experience of Care and Abuse (CECA) interview research findings and application in child and family services. It enables an accurate assessment of historical abuse, and its scoring system can be used on ongoing case files for children for better classification. A social and attachment model are described as explaining how damage from neglect and abuse can extend into later life.
Resocialization in crisis? – Review of the book Juvenile Delinquency: Theory, Practice and Law, 13th Edition by Larry J. Siegel and Brandon C. Welsh
Authors: JASTRZĘBSKA KINGA
Published: November 2019

Social maladjustment and juvenile delinquency is currently a serious worldwide problem, which is of interest not only to researchers and theoreticians, but also to society. This is due to the constantly growing scale of this phenomenon. It is worth noting that a steady increase in the number of juvenile crimes has been observed in Poland since 1990. Researchers presume that this is related to dynamic civilizational development, urbanization and technological progress, among others. It would seem that everything about juvenile delinquency has already been established; however, effective methods to counteract it still remain to be found. We are increasingly experiencing unjustified cases of violence at school, home as well as in public places, and teenage gangs can be found in most major cities. Hundreds of thousands of young people become victims of serious neglect, sexual violence and physical abuse every year.
THE INFLUENCE OF THE MUZZLE DEVICE ON THE SPREAD AND THE JUMP OF SELECTED RIFLES OF THE MODULAR SMALL ARMS SYSTEM MSBS-5,56
Authors: Goździk Dawid , Kijewski Jacek , Kupidura Przemysław , Szmit Łukasz
Published: November 2019

Results of tests, carried out so far for MSBS system rifles, have shown a large impact of muzzle devices on spread of shots pattern. In order to select the optimal design of the muzzle device, a series of firings were carried out, primarily with a light machine gun and a sniper rifle. It was assumed that a weapon jump, which is also the most easily measurable parameter, is the main factor affecting the shot pattern at precision firings. The jump parameters were determined by using a unique laboratory stand that allows measurement in conditions as close as possible to the real ones. Measurements of barrel movement were also made for selected designs with a high speed camera. The results of laboratory tests were verified by shootings on the range.
Gerald Vizenor. Native Provenance: The Betrayal of Cultural Creativity.
Authors: Punzalan Ricardo L.
Published: November 2019

This is a critical moment for those who care for Native American and Indigenous archives. After much discussion, debate, and years of tireless advocacy, the Protocols for Native American Archival Materials has finally been endorsed by our leading professional organizations. The Association of College and Research Libraries, following the request of the Rare Books and Manuscript Section (RBMS), endorsed the Protocols in August 2019. In 2018, the Council of the Society of American Archivists unanimously endorsed the Protocols, accompanied by an apology for the many years of inaction. Following these endorsements, the next step for us is not only to continue its promotion and implementation, but also grow our understanding of what it means to be responsible stewards of items in our care. The Protocols articulate foundational concepts for our professional practice, including notions of cultural sensitivity and reciprocity. We can further expand our thinking and practice in this area by engaging with the works of prominent thinkers. Among these is Anishinaabe cultural theorist, writer, and scholar Gerald Vizenor’s most recent book, Native Provenance: The Betrayal of Cultural Creativity.

Special collections in academic libraries provide rich learning environments for student engagement. This article describes the introduction of an independent study course by an academic library department as a high-impact educational practice supporting undergraduate research. Under the supervision of the faculty archivist, the student in this study was challenged to discover and research “gems,” unusual or significant items, on a topic of her choosing. She selected three works related to James Joyce’s Finnegans Wake, showcasing her research at the university’s Student Faculty Research Symposium and creating a library display as her final project. This case study explores background information and describes the course, its inception, and the student’s project. It includes a discussion of benefits and challenges, transferability, scalability, and the application of a constructivist approach to teaching and learning. Limitations and further research are also included in this study.

Resumen: Este artículo de corte cualitativo tiene como objetivo realizar una investigación evaluativa y analítica de la intervención social con adolescentes de procedencia rumana y etnia gitana en los asentamientos de El Gallinero (Madrid) y Thiers-benauge (Burdeos), con el fin de establecer estrategias para proyectos de Trabajo Social con dichos colectivos. Los hallazgos han posibilitado por un lado, el conocimiento de una población estigmatizada y que vive en condiciones de vulnerabilidad social en la periferia de grandes ciudades, y por otro, el papel trascendental que alberga la movilidad laboral para dicha población. Promover un enfoque de intervención integral donde se creen redes colaborativas entre las administraciones públicas, las entidades sociales y la propia población, sería un modo de avanzar en la igualdad de oportunidades sobre todo en etapas como la adolescencia.Abstract: This qualitative article aims to conduct an evaluative and analytical investigation of the social intervention with Romanian and gypsy teenagers in the settlements of El Gallinero (Madrid) and Thiers-Benauge (Bordeaux), in order to establish strategies for Social Work projects with these groups. The findings have made possible, on the one hand, the knowledge of a stigmatized population living in conditions of social vulnerability in the periphery of large cities, and on the other, the transcendental role that houses labor mobility for said population. Promoting a comprehensive intervention approach where collaborative networks are created between public administrations, social entities and the population itself, would be a way to advance equality of opportunities especially in stages such as adolescence.

Published: November 2019

The use of highly dispersed ilmenite ore in the titanium concentrate enrichment technology is accompanied by high dustiness at the stage of titanium charge preparation, which inevitably leads to technological losses and adversely affects the working conditions of the staff. In connection with this, the aim of the present work was to study the process of granulating ilmenite concentrate from the Malyshevsky deposit by pelletization. The size and morphology of ilmenite concentrate particles were determined using a high-resolution electron scanning microscope and a laser diffraction particle size analyzer. The granulation process was carried out in a drum granulator thermostated by assessing the effect of temperature, rotation speed granulator, process duration and a binder flow rate on particle size distribution and static strength formed granules of the title product. During the investigations it was established that the maximum yield of granules fraction of 1.0 - 5.0 mm was obtained using an aqueous solution of molasses molasses volume ratio: water = 5:1. The use as undiluted molasses binder leads to a strong increase in ductility formed mass and negatively affects the possibility of producing a granular product. It was shown that with increasing concentration of binder in the composition of the starting mixture the average yield and static strength of granules fraction of 1.0 - 5.0 mm increases, due to the uniform distribution of the solution between the ilmenite concentrate particles. At the same time when the amount of binder in the composition of the starting raw materials over 9.5% the formation of relatively large lumps is observed, which size is more than 5.0 mm. It has been experimentally proved that with increasing duration pelletization yield pellets of ilmenite concentrate fraction of 1.0 - 5.0 mm increases, passing through a maximum at 300 s.

Aromatic nitro compounds, such as nitro anilines and its halogen derivatives, are widely used in the industrial synthesis of dispersed azo dyes and some pharmaceutical products. For its preparation the processes of heterogeneous catalysis in various liquid media are used. One of the most important stages of catalysis, which in some cases determines its rate, is adsorption. The study of the nitro compounds adsorption from aqueous and non-aqueous solvents on the heterogeneous catalysts surface makes it possible to reveal the catalytic hydrogenation intimate mechanism features and the solvent influence on the hydrogenation process. In this work, we studied the 2-chloro-4-nitroaniline adsorption on active carbon from 2-propanol solutions at 293 and 313 K. Adsorption isotherms, two-dimensional state diagrams of the surface layers were obtained, and the isosteric heats of the process were calculated. The experimental adsorption isotherms are described in the framework of the volume filling of micropores for mesoporous adsorbents theory. The heat of adsorption is negative and decreases in absolute value with increasing degree of surface filling. On two-dimensional surface layers state diagrams the breaks presence, which corresponds to two-dimensional phase transitions, similar to second-order transitions in surface films. This fact indicates changes in the surface layers state with an increase in the degree of filling the coal surface with adsorbate, is observed.

The regularities of sorption of nickel (II) ions from a monocomponent system on macroporous weakly acidic cationite Lewatit MonoPlus TP 207 were studied. Sorption isotherms were obtained. It is shown that the extraction process can be fairly reliably described by Langmuir and Freundlich equations. The static exchange capacity (SEC) of the resin was determined. The SEC dependencies at temperatures of 305 and 328 K during the sorption process were revealed. Integral kinetic curves were obtained. It is defined that the equilibrium concentration of nickel (II) ions is reached about 13 times faster with temperature increase from 305 to 328 K. The experimental data were processed using equations that take into account the influence of external, internal diffusion, "sorbent-sorbate" and "sorbate-sorbate" chemical interactions. It was found that the main limiting stage of sorption of nickel (II) ions is the internal diffusion. The values of external and internal diffusion rate constants at the indicated temperatures were determined. The kinetic curves were processed by pseudo first and pseudo second order models, which satisfactorily describe the experimental data. According to transition-state theory the thermodynamic characteristics of the activation process (activation energy, entropy, enthalpy, and Gibbs free energy) were calculated. Relatively low activation energy indicates the decisive contribution of diffusion in the process of sorption of nickel (II) ions. Positive entropy is the evidence of nickel hydration shells destruction during the sorption process. Positive enthalpy proves an endothermic nature of interaction of nickel (II) ions and ionogenic groups. Negative Gibbs free energy witnesses to spontaneous course of the reaction in the forward direction. For known values of stability constants the contents of nickel ionic forms and SEC’s were calculated in terms of pH value. Nickel extraction from solution increases with the appearance of singly-charged NiOH+ ions in the pH range from 8 to 9.

Published: November 2019

The paper presents the results of the experimental research of a two-stage process for styrene production from butadiene-1,3 by a sequential synthesis of the butadiene-1,3 (4-vinylcyclohexene-1 and cyclooctadiene) cyclodimers in the first stage and styrene – in the second stage. The purpose of the research is to increase the productivity of the process and its selectivity and to simplify the technology for producing styrene and ethylbenzene from one type of raw material – n-butane. The possibility of producing 4-vinylcyclohexene-1 and cyclooctadiene by thermal and catalytic butadiene-1,3 dimerization on batch and continuous installations using copper nitrate, copper [Cu(NH3)4] (NO2) complex salt, iron pentacarbonyl, iron trichloride as catalysts is shown, as well as the regularities of the thermal butadiene dimerization process in the gas phase are established. The goal has been achieved by carrying out the synthesis of butadiene dimers on a flow-through installation in the gas phase at a high temperature and low pressure, in the presence of water vapor and a gum inhibitor. The results of laboratory research of the process for the styrene production by 4-vinylcyclohexene-1 dehydrogenation at the industrial catalysts for the hydrocarbons dehydrogenation: palladium 1.0% Pd/γ-Al2O3 (AP), platinum 0.6% Pt/γ-Al2O3 (IP-62), iron-chromium-potassium oxide (K-28) aluminum-chromium granulated for one-step dehydrogenation of n-butane produced by "Houdry" are presented. The possibility of styrene production by 4-vinylcyclohexene-1 dehydrogenation at the industrial catalyst for the ethylbenzene dehydrogenation has been established. It is shown that turning 4-vinylcyclohexene-1 into styrene occurs with an increase in temperature above 400 °C through the ethylbenzene-forming stage. When dehydrating 4-vinylcyclohexene-1, selectivity for ethylbenzene on the aluminum-chromium catalyst for the dehydrogenation of paraffin hydrocarbons with the composition of 18–20% Cr2O3, γAl2O3 has been revealed. According to the results obtained, optimal conditions for the process have been chosen.

This article considers the possibility of studying the main types of products of chemical production (ethylene, benzene, styrene and ethylene polymers in primary forms, styrene in primary forms, vinyl chloride in primary forms and propylene in primary forms, as well as methanol-synthetic poison, methanol-rectification technical forest chemical, methanol raw in terms of rectification) in thousand tons. The purpose of this work was to analyze the volume of the main types of chemical products. The objectives of the study were to determine the volume of production of chemical production, calculation of the seasonality index and forecasting the volume of the main types of products of chemical production. The results showed that the largest decrease in production was observed in 2012 for ethylene and benzene (93.2% and 97.2%), compared to 2011, respectively. For methanol production, on the contrary, in 2012, compared to 2011, there was an increase in production volumes (90.7%). The obtained calculations of the seasonality index showed that the lowest volume of production of benzene, methanol, polyethylene, polystyrene and ethylene was observed in January, styrene, polyvinyl chloride, polypropylene-in October, and the highest in August, except for the production of polyvinyl chloride. The forecast of volumes of production of the main types of production of chemicals for the period: january – december 2020 is constructed. The results obtained indicate that there will be an increase in production volumes.

The ribosomal P-stalk couples amino acid starvation to GCN2 activation in mammalian cells

Published: November 2019

The eukaryotic translation initiation factor 2α (eIF2α) kinase GCN2 is activated by amino acid starvation to elicit a rectifying physiological program known as the Integrated Stress Response (ISR). A role for uncharged tRNAs as activating ligands of yeast GCN2 is supported experimentally. However, mouse GCN2 activation has recently been observed in circumstances associated with ribosome stalling with no global increase in uncharged tRNAs. We report on a mammalian CHO cell-based CRISPR-Cas9 mutagenesis screen for genes that contribute to ISR activation by amino acid starvation. Disruption of genes encoding components of the ribosome P-stalk, uL10 and P1, selectively attenuated GCN2-mediated ISR activation by amino acid starvation or interference with tRNA charging without affecting the endoplasmic reticulum unfolded protein stress-induced ISR, mediated by the related eIF2α kinase PERK. Wildtype ribosomes isolated from CHO cells, but not those with P-stalk lesions, stimulated GCN2-dependent eIF2α phosphorylation in vitro. These observations support a model whereby lack of a cognate charged tRNA exposes a latent capacity of the ribosome P-stalk to activate GCN2 in cells and help explain the emerging link between ribosome stalling and ISR activation.
