Bromelain-based enzymatic debridement of e-cigarette burns: a single unit experience
Authors: Ho Weiguang , Jones Christopher D. , Widdowson Daniel , Bahia Hilal
Published: November 2019

Objective:

It is widely accepted that the early debridement of burns improves outcome. There is increasing evidence that enzymatic debridement is an effective technique for removal of full-thickness and deep-dermal burns, reducing blood loss and often the need for autologous skin grafting by avoiding over excision of the burn. We aim to highlight the potential use of this form of debridement as an alternative to surgical management in patients with electronic cigarette (e-cigarette)-associated flame burn injuries.

Methods:

This case series presents the use of Nexobrid (MediWound Ltd, Israel), a non-surgical, bromelain-based enzymatic debridement technique, in patients with deep partial-thickness burns (range: 1–3% total body surface area), avoiding the need for autologous skin grafting.

Results:

Burn wounds in two patients healed within 14 days without complications or the need for further surgical intervention. Another patient required further dressings after discharge but failed to attend follow-up appointments. These results are comparable with those reported by others using conservative management of e-cigarette burns.

Conclusion:

The authors wish to raise awareness of the potential for a combination of thermal and chemical burns related to e-cigarette explosions. Chemical burns should be excluded by pH testing of the burn wound. From our experience, small e-cigarette-associated flame burns can be considered for management with enzymatic debridement.

Analisa-se a viabilidade de pesquisas sobre usuários de ônibus com base na detecção de endereços MAC WiFi de dispositivos portáteis. A motivação para o estudo decorre da aparente contradição entre casos de sucesso publicados na literatura e resultados de experimentos de campo que realizamos. Requisitos para identificação adequada de passageiros de ônibus são usados como base para avaliar as capacidades do hardware e software de detecção comumente disponíveis. Mais especificamente, os intervalos de tempo decorridos entre as detecções do mesmo dispositivo são tomados como requisito para a determinação do estado do portador do dispositivo e, portanto, a identificação deste como passageiro. Por exemplo, ao realizar pesquisas de embarque e desembarque com equipamentos de detecção instalados a bordo, é necessário que várias detecções ocorram logo após o embarque do passageiro e antes do desembarque, permitindo assim uma estimativa precisa da origem e destino da viagem. Resultados experimentais em ensaios controlados e não controlados indicam que os componentes disponíveis no mercado com software de código aberto podem não fornecer detecções bem-sucedidas. No experimento controlado, encontramos tempos de 40 s para a primeira detecção de 86% dos dispositivos e uma média de 80 s para a segunda detecção de dispositivos. Para o experimento não controlado de viagens em ônibus com carregamento médio, foram encontradas diferenças significativas entre as contagens manuais e os dispositivos detectados. Como resultado dessas observações empíricas, recomenda-se uma avaliação cuidadosa dos esquemas de detecção existentes usados nas pesquisas de número de passageiros.

Published: November 2019

Simuladores de tráfego permitem avaliar cenários de maneira segura e com baixo custo. Todavia, os modelos matemáticos que os regem são ajustados para cenários frequentes no país de origem do simulador. No VISSIM, os modelos referentes ao deslocamento de caminhões simulam veículos com melhor desempenho, se comparados aos caminhões brasileiros. Este trabalho apresenta a calibração das funções de aceleração para caminhões do VISSIM, utilizando a diferença entre perfis de velocidade simulados e reais como medidas de ajuste. Usando GPS, foram obtidos perfis individuais para 57 caminhões que trafegaram por cerca de 18 km ao longo de uma rodovia de pista dupla em relevo ondulado, sob baixo fluxo de tráfego. A calibração foi automatizada por meio de um algoritmo genético. Diversas execuções do algoritmo foram realizadas, variando número de gerações e tamanho populacional. As funções de aceleração obtidas são apresentadas e discutidas.
TRACK GAUGE STABILITY UNDER EFFECT OF SLEEPER THERMAL EXPANSION
Authors: Lojda Vít , Krejčiříková Hana
Published: November 2019

Railway sleepers are traditionally made of hardwood, pre-stressed concrete or steel. However, emerging advanced materials, including polymers or composites, are investigated for a possible employment in the sleeper production. The main function of sleepers is to distribute forces they carry onto the trackbed, to support rails and keep the spacing between them, called the track gauge. The operating tolerance of the track gauge is critical for safety and is set by regulations. Generally, it is advisable to keep the track gauge deviation, as well as the sleeper length deviation influencing it, as low as reasonably practicable. In this article, the recommended limit values of the thermal expansion coefficient characterizing possible sleeper length deviation were evaluated. The recommendation considered allowed track gauge tolerance and the experimentally determined temperatures of a sleeper measured in the trackbed for a year. In addition, thermal expansion of a selected polymer in laboratory conditions was determined, representing an alternative material for the sleeper production. Consequently, it was compared with the limit and conservatively used materials. Furthermore, the same tested polymer, but utilizing chopped glass fibres to reduce the thermal expansion of the polymer, was also tested. Results show a positive impact of the glass reinforcement on the thermal expansion coefficient. The applicability of the selected polymer in the railway sleeper production from the perspective of the thermal expansion was discussed in the paper.

In a period of industrial expansion, protection of the environment is often neglected during the mass manufacture of products. One of the problems of our society that is necessary to face at present is the provision, processing and then usage of waste composed of fine particles that are extremely dangerous for mankind. This study looks at the processing of the fine dust resulting from the manufacture of brake pads. The selected technologies for the process of dust treatment were compaction, extrusion and tumbling granulation, and their consequent comparison with the strength of a break and disintegration of agglomerates from fine dust. The experiments were performed on a unique equipment that made it possible to process such dust in the form of larger units and thus reduce their dustiness, with this dust being reintroduced into the technologies for repeat processing or used for energy processing, in a cement kiln, for example.
Finitud y Verdad. Gadamer sobre la comprensión crítica
Authors: Fernández Membrive Miguel
Published: November 2019

Al mostrar las implicaciones de los conceptos gadamerianos de “anticipación de la perfección” (Vorgriff der Vollkommenheit) e “historia efectual” (Wirkungsgeschichtlichen), así como la relación que mantienen entre sí, el autor se propone explicar por qué en la filosofía de Gadamer el tradicional problema hermenéutico de una más adecuada comprensión de los “otros” queda subordinado al problema de la posible verdad de lo que éstos dicen. Asimismo, el autor sugiere que este último problema y el marco dialógico que Gadamer presupone como única posibilidad de afrontarlo, constituyen la clave principal para entender las diferencias entre su pensamiento y la tradición hermenéutica que lo precede, incluido –pese a su influencia directa- Martin Heidegger.
Derecho, delito y pena. Una mirada desde la Filosofía del Derecho de Hegel
Authors: Lassalle Martina
Published: November 2019

El presente trabajo se propone recuperar los principales aportes de Hegel sobre el problema del delito y la pena en el esquema que presenta en la Filosofía del Derecho, haciendo un continuo esfuerzo por enmarcarlos en su compleja propuesta filosófica más general, es decir, en el marco del movimiento dialéctico con el que piensa el continuo hacerse de las sociedades y los sujetos. Buscaremos principalmente mostrar el modo en que Hegel rechaza las concepciones utilitaristas sobre la pena (prevención, disuasión, corrección) para proponer una idea del castigo en tanto retribución, pero donde retribución adquiere un sentido peculiar que, consideramos, sólo puede ser leído a la luz de su dialéctica y de su singular concepción del derecho.
Verdad, juicio y evidencia en la obra de Franz Brentano
Authors: Niel Luis
Published: November 2019

El artículo aborda el tema de la verdad en la obra de Franz Brentano. Sin dejar de reconocer el carácter fragmentario, no sistemático, ni definitivo de su ‘teoría de la verdad’, la propuesta consiste en reconstruir su posición, dispersa en conferencias, cartas y manuscritos, y mostrar la riqueza de sus entramadas reflexiones, que interpretaremos como una suerte de ‘descripción fenomenológica’ del aparecer de la verdad en sus formas más elementales. Primero, analizaremos su conocida conferencia de 1889, en donde cuestiona críticamente las limitaciones inherentes a la clásica versión de la verdad en tanto adaequatio, y presenta, in nuce, ciertos aspectos que serán desarrollados en escritos posteriores, tales como la relación entre verdad e intuición. Segundo, nos detendremos en su teoría del juicio para señalar su concepción de que el juicio existencial es la forma fundamental de todo juicio (y no el juicio predicativo) y que la verdad se funda sobre la base de dicho juicio existencial. Tercero, mostraremos cómo en sus últimos escritos, Brentano asocia la verdad con el concepto de evidencia. Presentaremos su concepción de la verdad en tanto dación de algo en evidencia a partir del juicio existencial, presupuesto fundamental de cualquier concepción teórica de la verdad.

Many modern applications produce massive amounts of data series that need to be analyzed, requiring efficient similarity search operations. However, the state-of-the-art data series indexes that are used for this purpose do not scale well for massive datasets in terms of performance, or storage costs. We pinpoint the problem to the fact that existing summarizations of data series used for indexing cannot be sorted while keeping similar data series close to each other in the sorted order. This leads to two design problems. First, traditional bulk-loading algorithms based on sorting cannot be used. Instead, index construction takes place through slow top-down insertions, which create a non-contiguous index that results in many random I/Os. Second, data series cannot be sorted and split across nodes evenly based on their median value; thus, most leaf nodes are in practice nearly empty. This further slows down query speed and amplifies storage costs. To address these problems, we present Coconut. The first innovation in Coconut is an inverted, sortable data series summarization that organizes data series based on a z-order curve, keeping similar series close to each other in the sorted order. As a result, Coconut is able to use bulk-loading techniques that rely on sorting to quickly build a contiguous index using large sequential disk I/Os. We then explore prefix-based and median-based splitting policies for bottom-up bulk-loading, showing that median-based splitting outperforms the state of the art, ensuring that all nodes are densely populated. Overall, we show analytically and empirically that Coconut dominates the state-of-the-art data series indexes in terms of construction speed, query speed, and storage costs.
Everything you always wanted to know about compiled and vectorized queries but were afraid to ask
Authors: Kersten Timo , Leis Viktor , Kemper Alfons , Neumann Thomas , Pavlo Andrew , Boncz Peter
Published: November 2019

The query engines of most modern database systems are either based on vectorization or data-centric code generation. These two state-of-the-art query processing paradigms are fundamentally different in terms of system structure and query execution code. Both paradigms were used to build fast systems. However, until today it is not clear which paradigm yields faster query execution, as many implementation-specific choices obstruct a direct comparison of architectures. In this paper, we experimentally compare the two models by implementing both within the same test system. This allows us to use for both models the same query processing algorithms, the same data structures, and the same parallelization framework to ultimately create an apples-to-apples comparison. We find that both are efficient, but have different strengths and weaknesses. Vectorization is better at hiding cache miss latency, whereas data-centric compilation requires fewer CPU instructions, which benefits cache-resident workloads. Besides raw, single-threaded performance, we also investigate SIMD as well as multi-core parallelization and different hardware architectures. Finally, we analyze qualitative differences as a guide for system architects.
Nonlinear simulation of an elastic tumor-host interface
Authors: Lu Min-Jhe , Liu Chun , Li Shuwang
Published: November 2019

We develop a computational method for simulating the nonlinear dynamics of an elastic tumor-host interface. This work is motivated by the recent linear stability analysis of a two-phase tumor model with an elastic membrane interface in 2D [47]. Unlike the classic tumor model with surface tension, the elastic interface condition is numerically challenging due to the 4th order derivative from the Helfrich bending energy. Here we are interested in exploring the nonlinear interface dynamics in a sharp interface framework. We consider a curvature dependent bending rigidity (curvature weakening [22]) to investigate metastasis patterns such as chains or fingers that invade the host environment. We solve the nutrient field and the Stokes flow field using a spectrally accurate boundary integral method, and update the interface using a nonstiff semi-implicit approach. Numerical results suggest curvature weakening promotes the development of branching patterns instead of encapsulated morphologies in a long period of time. For non-weakened bending rigidity, we are able to find self-similar shrinking morphologies based on marginally stable value of the apoptosis rate.
Arguing with “at least” constructions
Authors: Katzir Nicole
Published: November 2019

Based on corpus data from the Hebrew web corpus HeTenTen, I analyze the discourse argumentative functions of constructions associated with superlative minimum modifiers (e. g.at least). I adopt Kay’s (1992. At least. In Adrienne Lehrer & Eva Feder Kittay (eds.),Frames, fields, and contrasts: New essays in semantic and lexical organization, 309–331. Hillsdale, NJ: Erlbaum) distinction between three such sub-constructions: Scalar, Rhetorical and Evaluative, but I offer further distinctions within these constructions. Most importantly, despite the differences between them, I argue that all three constructions are used to constructnon-optimal, yet sufficientarguments.
The Rise of Urbanized Landscapes in Mesopotamia: The QADIS Integrated Survey Results and the Interpretation of Multi-Layered Historical Landscapes

Published: November 2019

This paper draws on the preliminary results of the QADIS survey project, conducted by the University of Bologna and the Iraqi State Board of Antiquities and Heritage since 2016 in the Qadisiyah province. The project addresses phenomena related to anthropogenic transformation of landscapes in a region that was at the core of the early Mesopotamian urbanization process. Building upon the seminal work conducted by R. McC. Adams in the 1960 s and 1970 s, we implemented an integrated documentation technique to reconstruct at regional levels the changes in the dense network of human settlements and artificial water infrastructures characterizing the evolution of this archaeological landscape over time. The aim of the article is that of providing a finer-grained regional picture of 4th and 3rd millennium BC urban developments which can be useful for better conceptualizing the scale and pace of early Mesopotamian urbanism.
Sobre la asistencia a las víctimas de delitos más allá del Estatuto de la Víctima
Authors: De la Cuesta Aguado Paz Mercedes
Published: November 2019

La asistencia a las víctimas de delitos presenta aspectos que escapan a la genérica regulación legal o reglamentaria y que son propiamente cuestiones de organización, planificación e, incluso, de intendencia. Este artículo trata de sugerir medidas que faciliten la relación de las víctimas con el sistema judicial penal, que eviten la revictimización y nuevos procesos de victimización primaria y que, mejoren la calidad de vida de las víctimas y su percepción del sistema penal. Para ello se diferencian varios “grupos de víctimas de delitos”, dependiendo de los efectos de sus procesos de victimización, con la finalidad de sugerir medidas especialmente adecuadas para ellas, en un intento de poner de manifiesto la necesidad de superar la sectorialidad de la asistencia que se centra, sobre todo, en algunos grupos de víctimas, así como la desigual distribución territorial de las Oficinas de Asistencia a las víctimas (OAV).

Sollten die Regierungen in Deutschland und der Schweiz an der schwarzen Null festhalten?
Authors: Schaltegger Christoph A. , Truger Achim
Published: November 2019

An der schwarzen Null scheiden sich die Geister. Damit ist der stets ausgeglichene Bundeshaushalt gemeint. Vor allem international steht er ziemlich in der Kritik, weil die sparsamen Länder keine Impulse für die Weltwirtschaft geben würden. Doch auch national fordern viele Menschen mehr Ausgaben des Staates, beispielsweise für die Infrastruktur. Demgegenüber stehen weltweit steigende Staatsschulden, die künftige Generationen belasten und schnell zum Problem werden können, wenn die Zinsen wieder steigen. Gerade in Deutschland ist der Hang zur schwarzen Null derzeit groß, weil bei deren Aufgeben befürchtet wird, dass es schnell wieder in die andere Richtung geht. Die Ökonomen Christoph A. Schaltegger und Achim Truger sind unterschiedlicher Meinung, ob man in diesen konjunkturell eher schwierigen Zeiten daran festhalten sollte.

Demographics, Labour Market, and Pension Sustainability in Hungary
Authors: Németh András Olivér , Németh Petra , Vékás Péter
Published: November 2019

The sustainability of an unfunded pension system depends highly on demographic and labour market trends, i.e. how fertility, mortality, and employment rates change. In this paper we provide a brief summary of recent developments in these fields in Hungary and draw up a picture of the current situation. Then, we forecast the path of the economic old-age dependency ratio, i.e. the ratio of the elderly and employed populations. We make different alternative assumptions about fertility, mortality, and employment rates. According to our baseline scenario the dependency ratio is expected to rise from 40.6% to 77% by 2050. Such a sharp increase makes policy intervention inevitable. Based on our sensitivity analysis, the only viable remedy is increasing the retirement age.

Published: November 2019

Es indudable la importancia y necesidad de los productos fitosanitarios para mantener los niveles de producción de alimentos que demanda la población mundial; sin embargo, el constante e inadecuado uso de estos productos pudieran incorporar residuos de plaguicidas al suelo. El presente trabajo trata sobre la determinación múltiple de residuos de plaguicidas organofosforados en suelos del Municipio José María Vargas. El método desarrollado fue aplicado para la determinación de siete pesticidas: Metamidofos, Diazinon, Dimetoato, Clorpirifos, Malatión, Metilparatión, Tetraclorvinfos en muestras de suelo, se identificaron basados en sus tiempos de retención (tr) por comparación con los patrones. En la optimización del método se probó la extracción mecánica y la ultrasónica, resultando la extracción con agitación mecánica un método confiable para la determinación de pesticidas. Se puede decir que 6 de los 7 pesticidas estudiados fueron detectados en las 8 localidades. Del total de parcelas (75) estudiadas el 65,33% (49 parcelas) presentaron residuos de OPPs. El Clorpirifos se encuentra presente en todas las aldeas estudiadas, en cuanto al Malation este no fue detectado. Esto podría sugerir que la contaminación con estos plaguicidas, quizás sea debido a grandes cantidades aplicadas y alta frecuencia de aplicación. Cabe destacar en Venezuela no existe legislación que regule los límites de concentración de plaguicidas en el suelo por lo que no se puede afirmar que existe una contaminación como tal, es por esto que estudios de este tipo pueden ser tomados como referencia para la elaboración de normas que regulen el manejo de suelos.

TECHNOGENIC SAFETY OF GRAIN-PROCESSING ENTERPRISES
Authors: FESENKO O. O. , LYSYUK V. M. , SAKHAROVA Z. M.
Published: November 2019

The article deals with the issue of technogenic safety of grain processing enterprises. The legislative background of this issue is considered – the laws of Ukraine, regulatory legal acts. The grain processing industry contains a significant number of high-risk objects, potentially hazardous objects, where high-risk works are carried out. The most common emergencies and accidents found in the grain processing industries are those related to the explosion and fire hazard. The factors of fire and explosion and the fire hazard of enterprises for storage and processing of grain raw materials are given. The potential sources of ignition of grain raw materials and grain products, the causes of explosions of the dust air, gas-air or hybrid mixtures are specified. The list of the most common places and reasons for the ignition sources and explosions in technological structures and buildings, and the ways of flame propagation are given. The main dangerous factors that arise in the accident and the most fire-dangerous buildings of the grain-processing industry are presented. The grain-processing enterprises carry out high-risk works, which are covered by the special requirements, observance of which protects against accidents, but the level of occupational injuries, including those with deadly repercussions, remains high in the agro-industrial complex of Ukraine. One of the main causes of accidents resulting in death is the lack of permits for the execution of works and operation of equipment, machinery, mechanisms and high-risk objects. The works for the fulfilment of which the employer must have permission to hazardous work and the operation (use) of high-risk machines, machinery, equipment or declaration conformity of the material and technical resources to the requirements of occupational safety legislation are defined. The analysis of the hazards of grain processing industry enterprises helps to identify all possible emergencies and accidents. This is a compulsory procedure for the emergency response plan. The plans for localization and liquidation of the consequences of accidents in high-risk objects are developed for adjustment and coordination of the actions of the authorities and civil defence forces of the enterprise, institution, organization, whichowns or uses at least one high-risk object in case of threat or occurrence of emergencies. The plans are developed and approved by a legal entity or an individual, which owns or uses at least one high risk object, as well as enterprise, institution or organization that plans to operate or operates at least one high-risk object.

Abstract Brazil is considered the center of origin and diversity of passifloras. These species have a great importance to in natura fruits consumption, industrialization, medicinal use and also as ornamental plants. The different Passiflora speciesare host of a great diversity of arthropods that can cause injuries, economic damages and, in some situations, the plant death. Among the arthropods, leafhopper caterpillars are considered frequent and severe pests in the main passion fruit producing regions. The present work is an occurrence report of Isia alcumena and Spodoptera cosmioides attacking passion fruit plants (Passiflora edulis Sims) in the Federal District, Brazil. The S. cosmioides and S. eridania caterpillars were collected while consuming leaves of Passiflora edulis intra-specific hybrid located in the Germplasm Active Bank ‘Flor da Paixão’ at Embrapa Cerrados. The caterpillars of I. alcumena were collected on leaves of the Passiflora edulis cv. BRS Rubi do Cerrado at the Agricultural Support Unit, Embrapa Cerrados. After collected, the caterpillars were individualized in a breeding system with leaves of the host plants. The development of the caterpillar was accompanied until the emergence of the adults, which were identified and fixed in entomological pins for permanent dry preservation.

Published: November 2019

Abstract The objective of this study was to evaluate the influence of macronutrient and boron deficiencies on physico-chemical characteristics of pineapple fruits, ‘Vitoria’ cultivar. The experimental design was a randomized complete block with eight treatments (complete solution, -N, -P, -K, -Ca, -Mg, -S and -B) and six replicates. The experiment was conducted from October 2016 to March 2018, and the variables evaluated were: fresh fruit and crown mass, fruit diameter, fruit and crown length, juice volume and mass, titratable acidity (TA), soluble solids (SS), vitamin C, juice pH and SS/TA ratio. All treatments with nutrient deficiency reduced the fresh fruit mass. In treatments -N and -Ca there was a reduction of 41.9 and 35.3%, respectively, in the crown fresh mass. Fruits diameter under N, K and Mg deficiency was lower, fruit length, soluble solids and juice pH were lower in treatment with N deficiency. Isolated deficiencies of each of the macronutrients and B reduced the mass of the whole fruit and the crownless fruit. The nutrient that most limited the size and quality of ‘Vitoria’ pineapple fruit was nitrogen.

Published: November 2019

Abstract The objective of this research was to evaluate the production of passion fruit (Passiflora edulis Sims) cultivars in different nutrient solutions, using commercial Bioplant® substrate in slabs system in protected cultivation. A randomized complete block design in a factorial scheme was used with 2 passion fruit cultivars (Araguari and Yellow Master) x 4 nutrient solutions (solution 1, solution 2, solution 3 and solution 4), each plot consisting of 6 plants with 6 replications. Electrical conductivity evaluations in the slabs drained solution started at 15 days after seedling transplantation and the nutrient contents were quantified at the end of the research. In passion fruit, ether extract, crude fiber and crude protein were evaluated. Fruit number, pulp mass, peel thickness and gas exchange were evaluated. It was concluded that the use of nutrient solution 2 in cultivar Yellow Master, with 2.72 dS m-1 electrical conductivity and the use of nutrient solution 4 in cultivar Araguari, with 2.95 dS m-1 electrical conductivity, yielded the largest number of fruits, pulp mass, fruit mass and gas exchange, in slabs system in the protected cultivation of passion fruit.
O luto dos familiares de desaparecidos na Ditadura Militar e os movimentos de testemunho
Authors: Fustinoni Chiara Ferreira , Caniato Angela
Published: November 2019

Resumo Este artigo pretende compreender a forma como o processo de luto ocorreu entre os familiares de desaparecidos-mortos políticos durante a Ditadura Militar de 1964, que, valendo-se da Doutrina de Segurança Nacional, fez desaparecer militantes, ocasionando um hiato traumático no cerne das famílias, que precisaram lidar com o vazio próprio do desaparecido/desaparecimento. Sabendo que, para a elaboração do luto, se requer uma objetivação da morte - a identificação do corpo morto e os ritos de passagem da vida para a morte -, supomos haver dificuldade nessa possibilidade de elaboração do luto. Identificados com o trabalho freudiano Luto e melancolia, percorremos os dois caminhos por ele apresentados, sem intenção de abranger toda a complexidade humana no que tange às formas de sofrimento no luto, a saber: o luto e sua possibilidade de reinvestimento de libido; e os caminhos da melancolia, que paralisa o sujeito e impede que este faça novos investimentos pulsionais. Caminhando nos passos do pai da psicanálise, verificamos nos familiares de desaparecidos políticos que a melancolia paralisa o sujeito em um estado mortificante, enquanto no luto é possível algum movimento.

ABSTRACT: Considering that neem (Azadirachta indica A. Juss.) causes deleterious effects on fertility, the objective was to evaluate the effect of feeding quail (Coturnix coturnix japonica Linnaeus, 1758) of 90 days old with neem seeds on seminal quality, biometric parameters, and testicular morphometrics, as an experimental model. After the 30 day adaptation period to the experimental conditions, birds were randomly distributed in five treatments of neem seeds incorporated into feed, with 10 replicates: T1 (0%), T2 (5%), T3 (10%), T4 (20%) and T5 (40%). After 60 days of receiving experimental rations, their semen was collected to evaluate the sperm quality, the birds were euthanized, and testes were submitted to biometric, histological, and histomorphometric evaluation. The data were evaluated by analysis of variance and later by Tukey test with a significance level of 5%. The mean values of testicle weight, length, and width significantly decreased in T4 and T5, due degeneration of germinal epithelial cells. In these treatments, it occurred a significant increase (P>0.05) in the average values of the tunica albuginea thickness and a significant reduction in the values of the seminiferous tubule diameter and the height of the germinal epithelium. In addition, the mean values of seminal volume, sperm concentration, sperm motility, vigor, and sperm viability were significantly reduced. Thus, the use of neem in bird feeding, as well as the use for therapeutic purposes, is questionable, considering its negative impact on reproduction.

Abstract Plastic clays are one of the main raw materials used in ceramic technology. However, there is a shortage of good quality plastic clays in the world for use in porcelain technology. The aim of this study was to characterize plastic clays from Northeastern Brazil. Chemical and mineralogical composition, particle size distribution, plasticity and green strength of the clays were determined. The analyzed clays were predominantly composed of kaolinite and quartz, and some contained smectite. The amount of iron oxide in the clays was higher than 1.0% and for some of them the values were higher than 3%; the liquid and plastic limits ranged from 22% to 48% and 10% to 32%, respectively. According to characterization data, three plastic clays had potential to be used as alternative ball clay, due to their plasticity and mineralogical characteristics.

Abstract In this study, a new ceramic membrane type was used for the filtration of colored water. The membrane was prepared from local Algerian kaolin KT2 of Milia-type. The choice of this raw material was dictated by its natural abundance, to form the macroporous support prepared by the slip casting technique. A functional thin film layer (with a pore size of about 0.2 μm) produced by the sol-gel method was deposited on the support to reduce the porosity. A detailed study was conducted because of the importance of this layer and the improvement which brought to the filtration process. Ceramic membranes were tested for the removal of bromophenol red (BR) under a filtration pressure of 3 bar and a duration of 2 h of treatment. The results revealed a rejection rate of 100% for BR, especially after the addition of the inorganic layer. The material was characterized by DTA, TGA, XRD and SEM. The retention and the permeability of BR were also studied.
Physical and mechanical properties of low, ultralow and no cement refractory castables containing MgO nanoparticles developed in situ by means of polymeric resins

Published: November 2019

Abstract The introduction of MgO nanoparticles developed in situ in the matrix of high-alumina low cement, ultra-low and no cement refractory castables was made by means of a low viscosity containing aqueous polymeric resin, produced by the Pechini method. The addition of the liquid resin to the castables played two roles: first to serve as a supplier of mixing water and second as a precursor of nanoparticles of MgO, which were formed in situ in the castables matrices during firing. The results confirmed the benefits brought by the developed in situ MgO nanoparticles on the refractory properties of the investigated castables.

ABSTRACT The softwood pulp industry is based on the supply of Pinus taeda and P. elliottii woods, and competes for this raw material with other timber sectors. The study aimed to evaluate the wood quality of Pinus patula for pulp and paper production. Trees aged 14 years were obtained from a plantation located in Ponte Alta do Norte, State of Santa Catarina/Brazil. Discs were collected along the commercial height for determining the weighted basic density and its longitudinal variation in the trees, and the chemical composition. For the anatomical characterization, a disc was extracted from the base of each tree to determine the radial variation of tracheids morphological characteristics, and their quality indexes for the production of kraft pulp. The weighted basic density (365 kg.m-3) of the wood was low when compared with other species of the same genus. Regarding the tracheids morphology, a mean length of 2.37 mm; wall thickness of 5.49 µm; width of 40.32 µm and a lumen diameter of 29.09 µm were observed. The chemical composition of the species showed low contents of lignin (25.06%) and ashes (0.27%), compatible content of holocellulose (70.76%), and high content of extractives (6.24%) compared with conifers of traditional use. In general, P. patula species shows characteristics compatible with those traditionally used for the pulp and paper production, and it should be considered in more advanced studies with this species in this segment.

Abstract Yogurt is an important source of many biologically active peptides with specific health benefits. The majority of the bioactive peptides produced during yogurt manufacture are related to angiotensin converting enzyme inhibitory (ACE-I) peptides. The present study evaluated the proteolysis and angiotensin converting enzyme (ACE) inhibitory activities of non-fat probiotic yogurt supplemented with sodium caseinate (0 to 4%), and Mentha piperita (peppermint) extract (0 to 0.4%) during 20 days of storage. Good correlation (R = 0.90) was found between the growth of Lactobacillus casei LFTI® L26 and ACE inhibition in all samples during the initial stages of storage, as compared to the control yogurt, with a significant (p < 0.05) decrease after storage. The results showed that the addition of sodium caseinate and peppermint extract had a significant (p < 0.05) effect on proteolysis and the viability of L. casei LFTI® L26, enhancing the ACE activity. The IC50 values of the sample containing 0.4% of peppermint and of the sample containing 4% of sodium caseinate were 0.12 and 0.02 mg/mL respectively. The results showed that the use of 4% of sodium caseinate and 0.4% of peppermint extract could provide higher probiotic viability (1.3×107cfu/g) on the 20th day of storage.

Published: November 2019

Resumo A partir da investigação sobre os principais fundamentos ideológicos e pressupostos da organização associativa Escola sem Partido (ESP), com sede na cidade de São Paulo, este trabalho busca analisar as implicações das perspectivas e pautas defendidas pela associação para a educação e à sociedade brasileira na última década, abrangendo, mais especificamente, seus desdobramentos no âmbito do ensino da Sociologia no nível médio da educação básica. A pesquisa documental ocorreu junto aos meios de comunicação, eletrônicos e impressos, websites e redes sociais vinculadas ao ESP e abordadas a partir de contribuições da análise crítica do discurso. Como resultado, destacamos os conceitos de doutrinação ideológica e neutralidade do ensino propostos pelo ESP, seus temas e pautas que recaem sobre a questão do cerceamento da prática docente e aos componentes curriculares da disciplina de Sociologia, admitida apenas, quando se aproxime dos padrões nomotéticos de um conhecimento sociológico positivista e cientificista, reprodutores do seu projeto societário conservador.
Raça e Política de Assistência Social: Produção de Conhecimento em Psicologia Social
Authors: Oliveira Érika Cecília Soares , Rodrigues Luciana , Battistelli Bruna Moraes , Cruz Lilian Rodrigues da
Published: November 2019

Resumo Partimos da reflexão acerca das políticas públicas de Assistência Social e como as interfaces raça, racismo e branquitude emergem na produção de conhecimento. Inspiradas na ideia de pluriversalidade questionamos o universo conceitual branco, trazendo como reflexão as produções em Psicologia que se centram em um ideário eurocêntrico, masculinista e heterocentrado. Apresentamos uma discussão sobre o tema da raça e racismo, pensando como estes se articulam tanto na constituição e implementação das políticas públicas, quanto na sua precarização. Para finalizar, afirmamos a necessidade de descolonizar a produção em Psicologia Social, colocar a branquitude em jogo, dissolver a ideia de sujeito universal e assumir a necessidade de pensarmos e publicarmos a partir de uma perspectiva polirracional. Acreditamos que as políticas de produção de saberes e fazeres em Psicologia devem estar atentas à geopolítica do conhecimento, dialogando com diversidades epistêmicas espalhadas em distintas regiões do planeta, sobretudo aquelas do Sul Global.
Contribuições da Psicologia às Lutas Transversais Travadas em Meio às Metrópoles de Privilégios
Authors: Reis Carolina dos , Barbosa Roberta Brasilino
Published: November 2019

Resumo Esse artigo tem por objetivo refletir sobre as possibilidades de contribuição da Psicologia a ações de enfrentamento a práticas violentas, e junto às lutas transversais travadas pelos grupos com os quais trabalhamos. Para tanto, partimos do conceito de lutas transversais de Michel Foucault, entendidas como lutas antiautoritárias e democratizantes que têm por alvo os mecanismos de dominação, exploração e submissão. Entendemos que os saberes psis, ao se colocarem a serviço das lutas transversais, podem servir como ferramentas de análise e enfrentamento a estes mecanismos. Nesse sentido, trazemos duas experiências de pesquisa e extensão realizadas em territórios que se encontravam em meio a processos de remoção, um deles na Comunidade Indiana, no bairro Tijuca, no Rio de Janeiro e o outro na Grande Cruzeiro, em Porto Alegre. Tais análises assumem o caráter de denúncia das violências decorrentes de gestões estatais, dando visibilidade às formas de submissão que operam pela produção do que chamaremos de uma “subjetividade culpada” e pela inscrição das populações alvo das remoções no lugar de não cidadãos, de sujeitos de um não direito. Buscaremos, ainda, evidenciar as articulações entre essas ferramentas de produção de subjetividade e as problemáticas materiais, decorrentes das desigualdades de acesso à moradia e à cidade. Por fim, afirmamos o caráter de resistência presente na compreensão de subjetividade como processo em constante construção e nas possibilidades de produzirmos rupturas nas práticas que encerram determinados modos de habitar e viver nas cidades como mais ou menos legítimos.
