Legado do Congresso da Virada em tempos de conservadorismo reacionário
Authors: Mota Ana Elizabete , Rodrigues Mavi
Published: July 2020

Resumo O tema do artigo em tela é o III Congresso Brasileiro de Assistentes Sociais (CBAS), quatro décadas depois da sua realização. Duas são as hipóteses que trazemos para o debate: a primeira sugere que o principal legado do III CBAS se traduz na nova cultura profissional de horizonte progressista, forjada pela profissão na crise da ditadura de 1964, e que permitiu a elaboração de um projeto profissional comprometido com a emancipação humana; a segunda se refere ao quanto este legado se vê confrontado na conjuntura atual por uma nova fase de dominação burguesa, na qual a difusão de um conservadorismo reacionário, de caráter filo-fascista, é fundamental à implementação de uma agenda econômica ultraneoliberal no país.

Authors: Diehl Rodrigo Cristiano , Mendes Jussara Maria Rosa
Published: July 2020

Resumen Conjeturar el Estado, neoliberalismo, sistemas de protección social y los movimientos políticos y económicos en América Latina en el escenario actual es un desafío provocador. Aun así, el objetivo de este estudio es comprender el Estado de orientación neoliberal en América Latina y sus impactos en los sistemas de protección social. Dado este contexto de investigación, el problema de pesquisa es: ¿cuáles son las perspectivas que deben plantearse para comprender el Estado de orientación neoliberal en América Latina con respecto a los impactos en los sistemas de protección social? Para permitir el análisis de tal escenario, el artículo se dividió en dos momentos: el primero responsable por comprender el Estado de orientación neoliberal en América Latina y, el segundo, para analizar los sistemas de protección social y las influencias del neoliberalismo en su constitución. La metodología aplicada en la investigación se divide en tres ejes: para lograr los objetivos inicialmente propuestos se utilizará investigación exploratoria-descriptiva; para organizar y recopilar los materiales para el estudio, se utilizará la investigación bibliográfica cuantitativa y cualitativa y; para el tratamiento de estos datos, el método a emplear será el materialismo-dialéctico.
Capacidade de organização social em enfrentamentos socioambientais
Authors: Almeida Ricardo , Hayashi Carlos Roberto Massao
Published: July 2020

Resumo Este artigo descreve as etapas de uma pesquisa social que investigou a capacidade de organização de uma comunidade, localizada em Minas Gerais - Brasil, no enfrentamento de seus problemas socioambientais. Nos moldes de uma pesquisa participante, fez-se um diagnóstico para identificar os desafios e os potenciais mais relevantes da comunidade, os quais oportunizaram intervenções envolvendo três demandas prioritárias: melhoria das ações de educação ambiental na escola, mobilização comunitária para gestão dos resíduos eletrônicos e implementação de políticas socioambientais no município. Os resultados dessas intervenções evidenciaram que os atores sociais envolvidos, embora empenhem esforços para atuar nos enfrentamentos socioambientais, não conseguem perenizar ações a ponto de concretizar transformações mais significativas na comunidade, haja vista que no cenário prevalecem fatores como: visão superficial sobre o assunto, pouca valorização da participação coletiva por parte do poder público local e fragmentação no trabalho das lideranças comunitárias, os quais desencadeiam abandono das ações e descrédito da população nas tratativas socioambientais.

Early formation of belite in cement clinker raw materials with slag
Authors: Viggh Erik , Eriksson Matias , Wilhelmsson Bodil , Backman Rainer
Published: July 2020

Analytical methods for characterising cement raw meal during heating in different atmospheres were investigated. The effect of replacing limestone with 10 wt% slag on the formation of incipient belite and precursors of the clinker liquid in the temperature range 600–1050°C was quantified using thermogravimetry, X-ray diffraction and equilibrium calculations. The results showed that when calculating the lime saturation factor, slags were favoured to sand, resulting in lower amounts of quartz and C2S in the samples containing slag than the reference sample. This suggests that silicon dioxide in slag minerals did not react in this temperature range. The multi-component equilibrium results supported the phase formation sequence established. Allowing for the possible kinetic influences the potential solids solutions offered with the software was a valuable asset. The results showed that the effect of using slags to reduce the carbonate and sand content in a raw meal on potential amounts of incipient C2S was negative. At present, more detailed knowledge is needed regarding how blast-furnace slag and basic oxygen furnace slag contribute to the formation of intermediary compounds such as incipient C2S, C3A, C2F and C4AF in the solid phase at temperatures over 1050°C and affect the formation of C3S.
Application of time-of-day and day-of-week-based hazard in dam break assessments
Authors: Coombs Rhys
Published: July 2020

The consequences of failure for dams upstream of urban areas are usually considered to be severe, which can be reflected in a detailed hazard assessment as part of a dam break mapping exercise. These urban areas are usually populated with differing types of commercial and residential properties, all of which have different usage and occupancy both throughout a typical day and over a typical week. This study details a case study for a UK reservoir dam break model and documents – and discusses the differences between the often-adopted time-averaged values of population at risk and average societal loss of life, and an alternative proposed time-of-day and day-of-week consequence assessment technique. The study makes use of detailed two-dimensional hydraulic modelling techniques, and occupancy data from online application programming interfaces and other mass data collection surveys. The ramifications of the additional detail provided by the alternative approach are discussed and contextualised.
Stochastics and ecohydrology: a study in optimal reservoir design
Authors: Koskinas Aristotelis
Published: July 2020

The concept of environmental flow assessment is a crucial element of modified ecosystems featuring large infrastructure such as dams and reservoirs, but the relatively short length of available inputs raises questions about the reliability of any given environmental flow scheme. However, with the use of stochastics, it is possible to quantify these uncertainties, and present a solution that incorporates long-term persistence into a balanced reservoir simulation model. In this study, an attempt is made to determine a scheme that can produce a reliable timeseries of fluctuating environmental flows matching original river conditions to best accommodate local wildlife, in accordance with newer studies. The primary goal is to protect the ecosystem, and then secondarily to allow a steady supply of water for other uses. Using a synthetic timeseries based on historical inputs, it is possible to determine essential statistical flow characteristics, leading to a flow scheme that maximises environmental and human demand reliability. Undeniably, there seems to be a clear correlation between reliability and reservoir capacity, linking large sizes to cost-efficient design. However in an age characterised by an ever-changing climate and growing tensions between stakeholders, protecting the environment while also meeting design needs presents a daunting prospect for dam engineers.
Design of lightweight aluminum alloy building materials for corrosion and wear resistance
Authors: Hung Fei-Shuo
Published: July 2020

The use of lightweight, functional and eco-friendly building materials can reduce energy consumption and pollution levels. Aluminum (Al) alloys with low density, high specific strength, excellent functional properties and 100% recyclability make excellent building materials. Lightweight structures are crucial for safety, particularly for mitigating losses during natural disasters. Lightweight structures can considerably reduce losses, particularly casualties. Few studies have addressed building with aluminum alloys, but Taiwan’s innovative aluminum technologies are relevant for scholarly research regarding construction. The design of aluminum alloys in the construction field, particularly with regard to the wear resistance and corrosion characteristics of building materials in island countries, is vital to the upgrading and promotion of the construction industry. In this study, eco-friendly building materials (4389, 5089 and 6169) were compared with commercial materials (4032, 5052 and 6061). The results show that new types 4389, 5089 and 6169 have better material properties, microstructures, tensile mechanical properties and salt-spray test results than the commercial 4032, 5052 and 6061 materials, particularly corrosion resistance. It is worth noting that the new type 6169 has high strength extrusion. Materials, which can be used as a reference for the application of seashore industry, recreation parks or building structural support building materials.
Mechanical properties of complex configurations for nuclear containment structures
Authors: Zhang Chaobi , Lin Jing , Xu Hao
Published: July 2020

Investigation of the mechanical behaviour of nuclear containment vessels is important for evaluating their safety. A finite-element model based on an actual nuclear containment vessel was developed in this work. The influences of loading direction under uniaxial or biaxial loading on the mechanical behaviour of the vessel were assessed. The results indicate that the reinforcement configuration and the loading direction have a significant effect on the bearing capacity under uniaxial loading. As the reinforcement configurations in the considered specimens were different, the change trend of stress with loading ratio was significantly different under biaxial loading. The validity and reliability of the analysis were verified by several related finite-element simulations.
In-plane stiffness of precast monolithic floor composite structures
Authors: Zheng Xianchao , Chen Jinxiang , Li Qingning , Luo Shasha , Chang Xiaoling
Published: July 2020

The structural integrity of a steel frame–shear wall structural system with a precast floor cover was experimentally investigated. A test structure with a new precast floor (SJ2) and a test structure with a cast in situ floor (SJ1) were subjected to shaking table tests. It was found that the natural frequencies of both specimens were similar. Under the action of different levels of seismic waves, the new precast monolithic floor and the cast in situ floor maintained the transmission of seismic shearing forces, thereby allowing the lateral-load-resisting members to function co-operatively. The maximum inertial forces and storey shearing forces of SJ2 and SJ1 differed depending on the seismic waveform and seismic loadings and for different storeys of the structure; some were basically the same, but the value of SJ2 was larger than that of SJ1 under some conditions. The difference in the amount of deformation was small, except for the deformation resulting from El Centro 200 cm/s2, for which the SJ2-to-SJ1 ratio of in-plane stiffness was 0.65. Thus, the novel precast structure (SJ2) that meets the requirements of engineering design would be applicable to a multi-storey reinforced concrete structure located in a seismic region.
Improved shell element for geometrically non-linear analysis of thin-walled structures
Authors: Rezaiee-Pajand Mohammad , Masoodi Amir R. , Arabi Elias
Published: July 2020

A six-node triangular shell element was developed to study the geometrically non-linear behaviour of open-section members. The present formulation is free from shear and membrane locking due to use of mixed interpolation of tensorial components scheme. Due to model thin-walled section, an improvement is considered to update the normal vectors of elements which are located at the angle between flange and web of section. In other words, an average of director vectors is employed for these elements in updating formulation. Moreover, the total Lagrangian formulation is employed to consider large displacement and rotation. An incremental iterative technique named generalised displacement control method is utilised to solve the governing equation. Several numerical examples are studied to illustrate the accuracy and predictability of the proposed formulation.

Published: July 2020

The lateral swelling pressure (LSP) and vertical swelling of a highly expansive soil supported by a retaining wall was studied. Experimental work was conducted by designing a physical laboratory model with dimensions of 900 × 600 mm in plan and 950 mm in height. The finite element method was used to simulate the retaining wall supporting highly expansive soil in saturated and unsaturated conditions using GeoStudio 2007. Verification of the physical model showed that the LSP increased linearly with the depth of the wall up to the maximum value of about 165 kPa at a depth of 0.6 m. Predictions during saturation and loading stages showed that the quantitative predictions were within the measurement accuracy. Numerical predictions of the LSP and vertical swelling were compatible with the experimental results. The vertical swelling and percentage decrease in swelling decreased with the depth of the soil. The percentage decrease in vertical swelling was 95.0% at 34 days and a depth of 0.6 m. The rate of swelling decreased with an increase in soil depth and the time required to reach an equilibrium state of swelling decreased linearly with soil depth.
The effect of soil–structure interaction on the along-wind response of high-rise buildings
Authors: Shirkhanghah Behnam , Eimani Kalehsar Houshyar
Published: July 2020

Rapid population growth tends to lead to the construction of tall buildings. It is thus necessary to study the influential parameters on the behaviour of tall structures due to wind action. Soil deformability is one parameter that can affect the aerodynamic behaviour of tall structures. In this work, the impact of wind on the standard tall building of the Commonwealth Advisory Aeronautical Research Council, placed on a raft footing, was numerically modelled using Abaqus software. The wind was defined by a power function in the boundary layer of the atmosphere. Stream turbulence was modelled using the implicit large eddy simulation technique and a co-simulation was used to exchange non-uniform loads from the fluid domain to the structural domain. The mechanical reaction of the footing–soil framework was modelled using a direct strategy. Infinite boundary conditions were added to the numerical model for simulation of free boundaries and appropriate contact elements for sliding and separation between subsurface components were considered. The fluid and structural solutions were compared with the mean and root mean square values of experimental estimations for an extensive range of reduced speeds. Numerical results for the framework with soil–structure interaction (SSI) were compared with those without SSI. The dynamic properties and reactions of the building subjected to wind loading were affected by the SSI and therefore engineers should consider these parameters to guarantee practical designs.
Investigation of BFRP bar reinforced geopolymer concrete filled BFRP tube columns
Authors: Hadi Muhammad N.S. , Ahmad Junaid , Yu Tao
Published: July 2020

An experimental investigation was carried out on a novel type of concrete-filled tube column, which used geopolymer concrete and basalt-fibre-reinforced-polymer reinforcing bars and confinement tube. Geopolymer concrete was used in place of ordinary Portland cement concrete to counter the sustainability challenges of conventional cement manufacture. Longitudinal basalt-fibre-reinforced-polymer bars were used to replace steel reinforcement to avoid corrosion, while basalt-fibre-reinforced-polymer tube confinement was used to replace the conventionally used steel helix to enhance strength and ductility. Compressive load–deformation behaviour of 200 mm dia., 800 mm high specimens under concentric, 25 mm eccentric, 50 mm eccentric and four-point bending loads was experimentally investigated. Experimental axial load–bending moment diagrams were then produced. Although geopolymer concrete is normally considered to be more brittle than Portland cement concrete, the test results showed that the specimens with geopolymer concrete were more ductile compared to those with Portland cement concrete. It was also found that increased load eccentricity resulted in ductility enhancement in specimens with both types of concrete with basalt-fibre-reinforced-polymer bars and tubes, while steel-reinforced specimens suffered loss of ductility with increased load eccentricity.
Effects of particulate air pollution on visual aesthetic preference
Authors: Zhao Jingwei , Huang Yidan , Tang Ting , Li Yange
Published: July 2020

Prior studies mainly focused on the effects of particulate air pollution on physiological health, relatively few researchers paid attention to psychological well-being. There is lacuna of knowledge on the effects of air pollution on aesthetic preferences. To fill this gap this study examines ten sample sites of urban green space, and eight photographs were taken on each site (seven photographs on the tenth site) in eight days, respectively. These photographs on a site contained the same scene. The aesthetic preference and perceived air quality of the photographs were evaluated by 766 participants, and wind speed, amount of clouds in the sky, particulate matter (PM2.5 and PM10) of each site were measured in situ when the photographs were taken. The results suggest that: (a) percentage of sky covered by cloud, PM2.5 and PM10 have significantly negative correlations with aesthetic preference and perceived air quality, while the regression analysis indicates that percentage of sky covered by cloud is the sole predictor for both aesthetic preference and perceived air quality; (b) perceived air quality is the reliable predictor of aesthetic preference. These findings contribute new knowledge to understand the particulate air pollution's effect on psychological well-being.

Published: July 2020

Medir el contenido de humedad (CH) de los agregados de concreto (ADC) en la fabricación de concreto premezclado es uno de los retos actuales en la industria de la construcción porque afecta a las propiedades finales del concreto. Actualmente los métodos que se utilizan para medir el CH en ADC son invasivos y destructivos. Este artículo presenta una técnica moderna basada en espectroscopía dieléctrica (ED), un método que al propagar microondas en el material correlaciona su constante dieléctrica (CD) y su CH. En esta investigación se ha utilizado este método en ADC. Tres diferentes canteras peruanas de ADC (Moyobamba, Sol-Sol y Cerro Mocho) han sido utilizadas. Los resultados demuestran que el sensor a una frecuencia de 1.5 GHz es capaz de detectar el CH en ADC con una regresión lineal de R2 = 95 %. En conclusión, se puede utilizar la ED como un método de sensado no invasivo y en línea de CH en ADC para ser utilizado en la industria de la construcción.

El objetivo de este trabajo fue desarrollar una red de monitorización de temperatura, humedad y calidad del aire en un centro de datos para la automatización del encendido y apagado del sistema de enfriamiento, ventilación y filtrado de aire usando Internet de las cosas (IoT-Internet of Things). Se puso en marcha una red con tecnología inalámbrica de largo alcance compuesta por cinco nodos esclavo, un nodo maestro y una interfaz de usuario. Los nodos esclavo transmiten periódicamente al nodo maestro el valor de las tres variables de ambiente. El nodo maestro envía la información recibida de los esclavos a un servidor en la nube para poder ser accedida desde una interfaz de usuario. Cuando el valor de alguna de las variables alcanza el umbral configurado se enciende el sistema de enfriamiento, ventilación y/o filtrado de aire, según sea el caso. Las pruebas mostraron que se logró una precisión menor a ±1.0 °C en la medida de temperatura, menor a ±2 % en la medida de humedad, menor a ±8 μg/m³ en la medida de la calidad del aire y un alcance de 11.5 kilómetros con línea de vista en la transmisión de datos en la red. Según estos resultados, la red puede ponerse en funcionamiento para la monitorización de sensores y procesos en otras instalaciones con este alcance.

Ценностные ориентации поколений сотрудников и организационная культура библиотеки
Authors: Гракова Елена Владиславовна , Маслакова Мария Владимировна , Далганова Татьяна Геннадьевна
Published: July 2020

В статье рассматриваются вопросы применения к анализу организационной культуры библиотеки теории поколений. Организационная культура библиотеки определяется как совокупность мировоззренческих представлений, ценностных ориентаций, моделей поведения и взаимоотношений в коллективе, независимо от занимаемого места в библиотеке разделяемых всеми ее членами.

В качестве ядра организационной культуры библиотеки рассматриваются ценности (личностные и профессиональные), оказывающие влияние на информационно-культурный капитал библиотеки. Для характеристики ценностных ориентаций рассмотрены некоторые положения теории поколений. Отмечается, что в современных библиотеках персонал состоит из представителей трех поколений: беби-бумеров, поколения Х и поколения Y. Указаны профессиональные ценности работников библиотек, их значимость в организационной культуре.

Изучение теории поколений имеет значение для построения и развития организационной культуры библиотек, обладающих разнородным составом сотрудников. Совершенствование организационной культуры библиотеки с точки зрения модернизации информационного профессионализма сотрудников и учета их ценностных ориентаций целесообразно в контексте теории поколений.

Цифровизация и медиатизация имеют двоякий эффект. Они усиливают включенность, повышают событийность, ускоряют процессуальность. С другой стороны, дигитальные технологии предоставляют беспрецедентные возможности по анонимизация зла и манипуляции общественным сознанием. Статья посвящена проблеме использования учащимися гаджетов во время нахождения в образовательных учреждениях России.

The Potential of Using Dynamic Strains in Earthquake Early Warning Applications
Authors: Farghal Noha , Barbour Andrew , Langbein John
Published: July 2020

We investigate the potential of using borehole strainmeter data from the Network of the Americas (NOTA) and the U.S. Geological Survey networks to estimate earthquake moment magnitudes for earthquake early warning (EEW) applications. We derive an empirical equation relating peak dynamic strain, earthquake moment magnitude, and hypocentral distance, and investigate the effects of different types of instrument calibration on model misfit. We find that raw (uncalibrated) strains fit the model as accurately as calibrated strains. We test the model by estimating moment magnitudes of the largest two earthquakes in the July 2019 Ridgecrest earthquake sequence—the M 6.4 foreshock and the M 7.1 mainshock—using two strainmeters located within ∼50  km of the rupture. In both the cases, the magnitude based on the dynamic strain component is within ∼0.1–0.4 magnitude units of the catalog moment magnitude. We then compare the temporal evolution of our strain-derived magnitudes for the largest two Ridgecrest events to the real-time performance of the ShakeAlert EEW System (SAS). The final magnitudes from NOTA borehole strainmeters are close to SAS real-time estimates for the M 6.4 foreshock, and significantly more accurate for the M 7.1 mainshock.

Using Large-Scale Additive Manufacturing as a Bridge Manufacturing Process in Response to Shortages in Personal Protective Equipment during the COVID-19 Outbreak
Authors: G. Bishopx Elizabeth , J. Leigh Simon
Published: July 2020

The global coronavirus disease (COVID)-19 pandemic has led to an international shortage of personal protective equipment (PPE), with traditional supply chains unable to cope with the significant demand leading to critical shortfalls. A number of open and crowdsourcing initiatives have sought to address this shortfall by producing equipment such as protective face shields using additive manufacturing techniques such as fused filament fabrication (FFF). This paper reports the process of designing and manufacturing protective face shields using large-scale additive manufacturing (LSAM) to produce the major thermoplastic components of the face shield. LSAM offers significant advantages over other additive manufacturing technologies in bridge manufacturing scenarios as a true transition between prototypes and mass production techniques such as injection molding. In the context of production of COVID-19 face shields, the ability to produce the optimized components in under 5 min compared to what would typically take 1 – 2 h using another additive manufacturing technologies meant that significant production volume could be achieved rapidly with minimal staffing.

Introduction: In recent years, the treatment strategy for infectious and autoimmune diseases has significantly changed. Up to now, cancer treatment has been conducted on the basis of clinical and pathological methods. The most common cancer treatments is limited to chemotherapy, radiation therapy and surgery. However, cancer treatment is still not optimal. Common challenges for treatment of certain disease, e.g. cancer, are: systematic and non-specific distribution of drug agents, intolerable toxicity, insufficient drug concentration at the site of treatment and drug resistance. In recent years, the development and application of nanotechnology has been considered revolutionary in the field of cancer treatment. This technology offers a unique way to early detection and treatment of cancer. Designing and developing o new drug delivery systems not only increases the drug activity in the target tissue, but also reduces the drug toxicity and leaves it in a controlled manner. Newcomer vesicles consist of non-ionic surfactants that are biodegradable, non-toxic, stable, and inexpensive and can be used for targeted drug delivery. The niosomal vesicles are composed of nonionic surfactants that are biodegradable, non-toxic, stable and lower cost; and it can be used for targeted drug delivery. The major advantages of niosomes can be mentioned: the greater chemical stability, high purity, the availability of various types of non-ionic surfactants, proper storage of drug and cheapness.
