Long-Term (1986–2018) Evolution of Channel Bars in Response to Combined Effects of Cascade Reservoirs in the Middle Reaches of the Hanjiang River
Authors: Zhang Yingying , Cai Xiaobin , Yang Chao , Li Enhua , Song Xinxin , Ban Xuan
Published: December 2019

Channel bars are essential landforms and their evolution is crucial to aquatic and riparian biodiversity, river’s water-sediment process, and economic development. With the development of water conservation facilities and hydropower projects, numerous changes have been taken place in hydrological regimes and morphology. There have been many changes on channel bars in the middle reaches of Hanjiang River due to the combined effects of cascade reservoirs. However, little was known about such dynamics and their linkages to cascade dams across the entire downstream area. Using Landsat remote sensing images from 1986–2018 and the threshold binary Otsu extraction method, this study completed comprehensive monitoring of nine mid-channel bars (DX1–DX7, XZ1, and XZ2), and three shoal group (XZ3–XZ5) dynamics. Results showed that the mid-channel bars’ area in the reach from Danjiangkou to Xiangyang (DX) decreased over the past 33 years, with the exception of DX4, while the total area decreased by 23.19%, this channel bars’ area change was mainly influenced by backwater from the Cuijiaying Reservoir with high water level after 2010 (r = −0.93, p < 0.01). The total channel bar area from Xiangyang to Huangzhuang (XZ) decreased by 16.63% from 1986 to 2018. The total channel bar area in XZ had a strong negative correlation with runoff at Huangzhuang hydrologic station (r = −0.79, p < 0.05), which was partly attributed to upstream precipitation according to the high correlation between runoff and precipitation (R2 = 0.65). In general, the DX section was under equilibrium between scouring and deposition compared to downstream Xiangyang, the bars in DX section were mainly affected by water level, and bars in XZ section during 1986–2018 were complicated because it was upstream eroded and downstream deposited. In addition, vegetation cover, revetments, flood events, sand mining, land use, and over-exploitation may cause channel bar area dynamics. Hence, more continuous investigations are suggested to focus on effects of cascade reservoir operation on hydrological regime, as well as the changing morphology of channel bars in the middle reaches of the Hanjiang River.

Published: December 2019

As eleições de 2018 no Brasil colocaram em destaque a circulação de informação política e os impactos da desinformação na formação da opinião pública. O declínio da confiança nas notícias veiculadas pela grande mídia foi terreno fértil para o aumento das fake news, que atuaram fortemente na produção de conteúdos sobre as campanhas. Nesse contexto, também chamou a atenção a utilização dos sites de redes sociais (SRSs) e o serviço móvel de mensagens instantâneas WhatsApp como espaço de formação de preferências, de pequenos comitês de campanha e de polarização ideológica. Neste artigo, examinamos as dinâmicas da apropriação política do WhatsApp, em comparação com o Facebook, com foco nas relações entre a desinformação e a formação da opinião pública sobre a política, tendo em vista o cenário eleitoral de 2018 e suas reverberações pós-eleitorais. Nos interessou observar os hábitos de consumo das mídias sociais e o grau de exposição às notícias falsas, bem como compreender a frequência e a intencionalidade de compartilhamento de fake news pelos usuários. Para tanto, utilizamos dados da pesquisa nacional "WhatsApp como fonte de engajamento político e (des)informação no Brasil" (N = 1.615).

Family Formation, Fertility, and Failure: A Literature Review on Price Increases and Their Impact on the Family Institution
Authors: Degner Jeffery
Published: December 2019

Inflation not only debases the value of currency by lowering purchasing power. It also serves to erode the quantity and quality of marriages while creating distortions in the decision-making processes of those hoping to form marriages and to have children. Furthermore, a loss of purchasing power helps to create relational tension for married couples, contributing to increasing divorce rates throughout the globe. As for the formation of families via marriage, the literature surrounding inflation and the family shows that price increases in higher education and housing both limit the number of first marriages as well raising the average age at which they occur. These phenomena are present in Western democracies, Islamic theocratic regimes, and highly-developed East Asian economies. Rising prices impact already married couples who would pro-create, but decide to accelerate or nearly eliminate child-bearing based on the inflationary environment in which they live. Finally, the literature shows that a loss of purchasing power leads to marital tension and higher rates of divorce. This trend is exhibited all over the world. This relationship occurs across cultural and religious systems as well as differing levels of economic development. While the problem of rising prices is economic in nature, it is shown to have deleterious effects upon the family institution.
Over the Cliff: How Brazil's 2004–2016 Business Cycle Became Its Worst Recession in a Century
Authors: Maia Henrique , Steinreich Dale , Saboia de Albuquerque Bruno
Published: December 2019

This paper analyzes Brazil’s 2004–16 business cycle, which subsumes what is now regarded as the nation’s most severe macroeconomic recession in more than a century. During the steep recession, which stretched over more than two years, national production at one point fell 3.8 percent per annum while the unemployment rate rose from 4.6 to as high as 11.9 percent. This study, after delineating its methodology, examines the behavior of different Brazilian macroeconomic aggregates during the cycle. These aggregates include GDP, the money supply, interest rates, savings, industrial production of higher- and lower-order goods, and inflation. Also examined are the Brazilian government’s interventions that rearranged Brazil’s structure of production and ignited an unsustainable boom, the role of price controls in prolonging economic recovery, and the recovery per se using the theoretical lens of the Austrian-adjustment process. Finally, empirical data from the recent Brazilian cycle will be analyzed in light of the predictions of Austrian business cycle theory (ABCT). The data were found overall to support the theory.

Oeste da Bahia: agricultura globalizada, desterritorialização e movimentos políticos emancipatórios
Authors: Sampaio Mateus De Almeida Prado
Published: December 2019

Este artigo aborda o processo de transformação sócio-espacial promovido pela expansão da agricultura científica globalizada no MATOPIBA, sobretudo no Oeste da Bahia, promotor de grandes impactos territoriais, sociais e ambientais. Com a implantação desse modelo de desenvolvimento agropecuário, novas contradições surgem e velhas contradições se acirram no processo ininterrupto de (re)construção do espaço agrário regional. A dinâmica de territorialização e desterritorialização de agentes sociais e de atividades produtivas entra em choque na região estudada, promovendo conflitos e violência. No plano geopolítico, antigos traços regionais são substituídos por novas feições, agenciando movimentos emancipacionistas em escala municipal, estadual e, eventualmente, também no âmbito macrorregional.

Os movimentos sociais são importantes expressões que de início já nos revelam alguns produtos da relação entre sujeito-estado-sociedade, se materializam em busca de espaços e territórios, esta intencionalidade, por sua vez, revela a nós, qual o cerne de atuação de um determinado movimento. O que diferencia um movimento A de um movimento B é, portanto, a sua intencionalidade, a sua forma de ação e suas estratégias que estão impressas no espaço num constante movimento progressivo e antagônico ao mesmo tempo. O presente trabalho está contido em uma abordagem qualitativa, evidenciando diferentes processos geográficos, históricos e sociais acerca do Movimento LGBT de Presidente Prudente - SP, foram diferentes os procedimentos metodológicos utilizados até aqui, como a aplicação de uma abordagem geográfica dos movimentos sociais identificadas como movimentos socioespaciais e socioterritoriais, bem como, levantamento bibliográfico, aplicação de entrevistas semiestruturadas e pesquisa documental. Esta pesquisa vem sendo desenvolvida há três anos (2017-2019), caminhando em diferentes ritmos e sentidos, para afinar e compreender melhor o estudo e leitura geográfica sobre os movimentos sociais. Esses movimentos são identificados neste trabalho como movimentos socioterritoriais e movimentos socioespaciais. Dentro do seio dessa discussão que vem sendo desenvolvida e afinada num coletivo de pensamento, colorimos a história do Movimento LGBT de Presidente Prudente - SP, identificado como um movimento socioespacial a partir de suas práticas e intencionalidades. Além de recompor seu histórico, realizamos também uma discussão socioterritorial a partir do corpo e trazemos para o debate: seria o corpo um território, um espaço, uma ferramenta de luta, ou apenas um conjunto de símbolos expressos socioespacialmente?
Potencialidades da produção de alimentos nas cidades: experiências de agricultura urbana no município de Pirapozinho – São Paulo
Authors: Mendes Daiara Batista
Published: December 2019

O presente artigo busca identificar as principais potencialidades intrínsecas à prática da agricultura urbana desenvolvida em Pirapozinho, um município de pequeno porte na região Oeste paulista, dando enfoque ao uso para alimentação e, sobretudo, econômico. Para tal análise, partiu-se de uma revisão bibliográfica sobre o tema agricultura urbana, agricultura de proximidade, entre outros, além de fontes de dados primários na área de estudo, tais como pesquisas de campo, entrevistas, observações participantes, dentre outras. Com base nestes resultados, nota-se que a prática de agricultura urbana tem se constituído como uma maneira de obter o acesso rápido a produtos de qualidade, visto sua proximidade com o consumidor que, na maioria das vezes, vive nos arredores dos locais de cultivo, ocasionando uma estreita ligação entre agricultor-consumidor, assim como entre o consumidor e o produto final. Verificou-se também que as práticas agrícolas em áreas urbanas não têm tido a devida atenção do ponto de vista governamental, tanto em escala nacional quanto em escala local, visto as suas potencialidades como uma atividade produtora de alimentos.

Authors: Battista Edurne , Justianovich Sergio , Ocampo Fernando
Published: December 2019

En Argentina, el alimento “leche” se inscribe en un modelo de producción y consumo concentrado en pocas empresas, que centralizan su procesamiento y distribución, con tendencia a la extranjerización de la propiedad. Este trabajo describe el diseño de un Sistema Producto Servicio orientado al producto “leche”, que habilita a familias productoras y pymes distribuidas en el territorio nacional a descentralizar su producción y distribución, permitiendo la apropiación local de los procesos productivos y de los productos, y asegurando la inocuidad del alimento. El objetivo es recuperar y analizar la trayectoria del caso a partir de las herramientas que se combinaron para la gestión del proceso de cambio: Análisis de Cadena Global de Valor (CGV), Análisis de Ciclo de Vida (ACV) y gestión de Relaciones Generativas. Los indicadores permiten concluir que la implementación del proyecto impacta de modo favorable en la dimensión económica, social y ambiental.

Cloud services among public and business companies have become popular in recent years. For production activities, many companies rely on cloud technology. Distributed Denial of Services (DDoS) attack is an extremely damaging general and critical type of cloud attacks. Several efforts have been made in recent years to identify numerous types of DDoS attacks. This paper discusses the different types of DDoS attacks and their cloud computing consequences. Distributed Denial of Service attack (DDoS) is a malicious attempt to disrupt the normal movement of a targeted server, service or network through influx of internet traffic overwhelming the target or its infrastructure. The use of multiple affected computer systems as a source of attacks makes DDoS attacks effective. Computers and other networked tools, including IoT phones, may be included on exploited machines. A DDoS attack from a high level resembles a traffic jam that is caused by roads that prevents normal travel at their desired destination. So DDoS Attack is a major challenging problem in integrated Cloud and IoT. Hence, this paper proposes Shield Advanced Mitigation System of Distributed Denial of Service Attack in the integration of Internet of Things and Cloud Computing Environment. This secure architecture use two verification process to identify whether user is legitimate or malicious. Dynamic Captcha Testing with Equal Probability test for first verification process, moreover Zigsaw Image Puzzle Test is used for second verification process, and Intrusion Detection Prevention System is used to identify and prevent malicious user, moreover reverse proxy is used to hide server location. These functional components and flow could strengthen security in Client side network to provide cloud services furthermore to overcome distributed denial of service attack in the integration of Internet of Things and Cloud Environment.

The present study revolves around the possibility of setting machining parameters in the drilling of composites of aluminum matrix (LM6/Fly ash) using the signal to noise ratio analysis. The aim of this work is to consider, the impact of input parameters, feed, speed, drill and percentage of composite material reinforcement on thrust force during AMCs drilling. AMCs were manufactured by the stir casting process with LM6 aluminium alloy as matrix material and fly ash as reinforcement material. Investigations were directed on a CNC vertical machining center for estimating thrust force. The Taguchi strategy for trial configuration is a generally admitted system employed for delivering great items requiring less effort. In the same way, L27 orthogonal array is employed for the analyses. The response table, graphs and variance analyzes are used to demonstrate the potential environment and the effects of machining parameters. It is evident that there is a tremendous improvement in the drilling procedure by using this methodology.

Analyzing various phases of mood using the verbal form of writing can serve as advancement in the field of psychology. The research work highlighted in this paper focuses on the use of sentiment analysis to predict the emotional state and vulnerability of written statements, as per the most generic perceptions, in the English language, with the help of an algorithm. The text pre-processing step discussed in this work involves cultivating and analyzing each word of user input, analyzing their literal and emotional essences to sum up the mood inclination of the statements and other parts-of-speech, to determine the specific mood and the vulnerability of the writing itself. The vulnerability level of the document is also determined, in order to extent out the purpose towards medical treatments where a vulnerable mindset, suffering from mental illness, depression, perceives the capability to inflict harm upon oneself or others can be given proper help and counseling.

Steel Plays major role in the field of construction industry. Due to Rapid industrialization and urbanization has increased to twofolds the demand and usage of materials. Increasing demand creates depletion of material. Excessive waste plastic creates Environmental pollution, in order to reduce the waste it can be converted into polymers and can be used in the field of construction industry. Waste material can be used to replace the steel material in concrete as an alternative source. Usage of synthetic material increases day by day due to its advantages. A study was carried out to understand the behavior of synthetic polymers to be used in different fields. The research work is carried out for different polymers. It is found from the results that Strength of synthetic polymers is more when compared with other polymers and can be used as reinforcement in concrete there by reducing the weight of concrete member. The application of using synthetic polymer in concrete is not only limited to the weight reduction but also it reduces the cost of construction. Cost of construction can be reduced in the following ways, First it does not need skilled labors, second reduces the corrosion risks. Synthetic polymer has higher tensile strength compared to conventional steel polymer, hence more investigation to be carried out to expose the potentiality of the material.

This paper presents the field programmable gate array (FPGA) implementation for the speed controlling of 8/6 switched reluctance motor (SRM) using conventional proportional integral (PI) controller. PI controller is tuned by trial and error method such that the actual speed of motor follows reference speed under different loading conditions. The main focus of the paper is to construct and implement the commutation table for consecutive excitation of the successive phases of SRM. In order to implement it, an inductance profile of SRM is stored into the ROM indicating the direction of the rotor. Four hall sensors are used to obtain the pulses from the respective phases and compared with inductance profile to excite the appropriate phases. The entire algorithm is modeled using Xilinx tool box and wavect controller to integrate SRM with asymmetric converter. The developed Xilinx model is validated for load and no-load condition and the experimental results are presented.

Energy storage systems are fundamental to the activity of intensity frameworks. They guarantee coherence of vitality supply and improve the dependability of the framework. The first area is centered on various energy storage frameworks, considering capacity limit, voltage and current proportions, and energy accessibility. Among the energy storage devices, supercapacitor is widely used because it is a high-limit capacitor with capacitance esteem a large amount than different capacitors. In the supercapacitor we have used MoS2 material synthesized with various Electrolytes. In perspective on the above mentioned, we report an Artificial Neural Network (ANN) strategy to achieve the predictable results. Levenberg- Marquardt feed-forward calculation prepares the neural network. We measure the exhibition of the ANN model with respect to mean square error (MSE) and the relationship coefficient between anticipated yield and yield given by the system. Results confirm the stability of supercapacitor over the other energy storage devices. To show such kind of conduct, we give Synthesis technique, Electrolyte, Cycle Life as an info esteems and Specific limit as yield esteem. For the amalgamation technique info esteem we have taken both compound and physical strategies by normalizing it. The practiced ANN demonstrating confirmations a higher number of concealed neuron design showing ideal execution as respects to expectation exactness

In geotechnical engineering practice, expansive clay is widely encountered. It poses to be a serious problem especially in metropolitan areas by virtue of its low strength and high compressibility. Further, these soils undergo significant change in volume as a consequence of variation in the moisture content. Soil stabilisation is one such technique practiced to improve the shear strength and to control volume change in expansive clays. Among various stabilisation techniques, Lime has been found to be an effective stabilizer, which appreciably alters the properties of expansive clay. Further, the reaction will be very effective on the usage of nano size particles in the stabilisation of expansive clay. At the first step, the effect of lime stabilisation on geotechnical properties such as grain size distribution, index properties, compaction characteristics, differential free swell and unconfined compressive strength of expansive clay was studied by varying percentages of lime. At the second step, the effect of nano- lime on the properties of optimum soil-lime mixture was investigated. The percentage of nano- lime is varied from 0.25- 1.0% by dry weight of the soil. The measured results show that the use of nano- lime in expansive clay significantly improves its strength and reduces swell behaviour resulting in reduced pavement thickness.

Rapid expansion of IoT technologies and their devices has created the considerable convenience in the daily lives of the people. Modernization of technique in IoT has allowed them to perform just more than sensing that directly means the more energy consumption. It is a known fact that most of the IoT devices have the limited power supply and hence it is an obvious need to design the energy efficient model. Despite of IoT devices being so useful in daily life and in other industries, data security is one of the primary concern in the fields of IoT application such as healthcare, agriculture, defense etc., and it is a challenging task to provide the data security in these fields. In past, several methods have been proposed to address this challenge, however, either they failed to provide the security or they lack from the efficiency. In this paper, it introduces a methodology named as ESDAM (Efficient and Secure Data Aggregation against Malicious Nodes) that provides better security with improved efficiency. The proposed methodology is parted into two methods, which helps in discerning the malicious nodes. First method, is through extending coordinates and the second method, is through surveilling the adjacent nodes. Extensive simulation has been performed by applying various constraints through persuading various number of malicious and performance metrics such as energy utilization, number of failed nodes, packet mismatch rate and packet discern rate. The performance evaluation of the simulation results proves that proposed methodology performs better than the existing methods.
