Mechanism Analysis and Process Inversion of the “7.26” Landslide in the West Open-Pit Mine of Fushun, China

Mine landslides are geological disasters with the highest frequency and cause the greatest harm worldwide. This typically causes significant casualties and damage to property. The study of the formation mechanisms and kinematic processes of mine landslides is important for the prevention and control of mine geological disasters and mine production safety. This study examined the “7.26” landslide, which occurred in the West Open-pit Mine of Fushun, China, in 2016, based on detailed investigations, interferometric synthetic aperture radar (InSAR) monitoring, and numerical simulations. The mechanism of landslide formation was explored, its kinematic process was inverted, and its disaster evolution process was summarized. The results indicate that: (1) For the formation mechanism of the “7.26” landslide, in July 2015, the old sliding mass was reactivated and deformed along the dominant joints in the shale. The following year, owing to continuous rainfall during the rainy season, the sliding surface accelerated its connection. Finally, a rainstorm on 25–26 July 2016, triggered slope instability. (2) The process of continued movement after landslide instability was approximately 250 s. It can be divided into the landslide initiation (0–10 s), collision scraping (10–150 s), and accumulation stages (150–250 s). (3) The entire process of landslide disasters includes four stages. During the weak-deformation stage, the maximum deformation of the sliding mass monitored by InSAR was approximately 50 mm. During the strong deformation stage, the tensile cracks at the rear edge of the landslide continued to expand, and shear outlets at the front edge had already formed. During the instability and failure stages, rainstorms trigger slope instability, leading to landslides. During the sliding accumulation stage, the landslide mass transformed into debris flow along the slope surface and accumulated at the bottom of the pit. This study provides a theoretical basis for the subsequent evaluation, treatment, monitoring, and warning of landslides in the Fushun West Open-pit Mine and other deep excavation open-pit mines.

A 2D roughness method for irregular interface of rock-backfill

A simple and reasonable roughness method for irregular interface of rock-backfill is significant for estimating the long-term stability of mine stopes in underground engineering. In this paper, two new concepts, contribution height difference (CHD) and average contribution height difference (ACHD), were presented through analyzing the influences of whole movement process of asperity and properties of contact material on the shear strength properties of interface. Occupying the presented concepts and combining with the fractal theory, a 2D roughness method for irregular interface of rock-backfill was created, which depends on fractal dimension Dp and direction-correlated parameter ACHD0. The roughness index Iif was introduced to quantitatively characterize the roughness of irregular interface. The results of scanning experiment and shear strength experiment about granite and cement backfill were used to verify the proposed 2D roughness method. The application analysis shows that the proposed roughness method has very outstanding advantage for irregular interface of rock-backfill, which provides the evolution of roughness method by involving the directionality of roughness and resolving the effect of sampling interval. The roughness index Iif can predict the shear strength of interface between rock and backfill. The parameters described in this work are easy to measure in field and also they are very convenient in usage.

Advances in ecotechnological methods for diffuse nutrient pollution control: wicked issues in agricultural and urban watersheds

Considerable time and funding have been committed to tackling nonpoint source (NPS) pollution in agricultural and urban watersheds . Notwithstanding all these efforts, the water quality in many AUWs has not significantly improved. Diffuse nutrient pollution involves the movement of these pollutants between soil and water. Excessive diffuse pollution has been accepted as one of the main causes of failure to attain favorable environmental conditions in freshwater systems. Recently, several technologies and practices have been implemented to manage diffuse pollution, namely: a) source reduction, b) pollutant retention over the movement process; c) nutrient recycling, and d) purification and restoration of the eutrophic water bodies. This paper synthesized the existing knowledge of key methods to tackle diffuse pollution from AUWs. Furthermore, the predominant purification mechanisms and impacting factors are explored, allowing a comprehensive and critical understanding of different control strategies to improve the management of diffuse pollution. Therefore, potential approaches for strengthening the performance of control technologies for diffuse pollution treatment and remediation are discussed. Although adopting source reduction strategies (e.g., the “4R” approach: right rate, right time, right source, and right placement of nutrients) could efficiently decrease surface runoff and pollutant levels, they may not stop runoff from entering nearby streams. Consequently, comprehensive treatment of agricultural runoff still requires extra process retention strategies. Overall, the findings of this paper showed that treatment system design and operational and environmental factors played crucial but variable roles in diffuse pollution treatment. Moreover, the results showed that combining or integrating constructed wetlands with other control technologies could enhance the comprehensive purification of diffuse pollution compared to using a single method. This review proposes a systematic approach for diffuse pollution control based on three components (water, soil and microbiota) and maximizing the regulating services of agroecosystems via land use/cover types. The current review contributes to the documentation of existing research trends. It sheds light on diffuse pollution control approaches in AUWs, and further encourages the development of this vital field.

Directional enhancement and potential reduction of thermal conductivity induced by one-dimensional nanoparticle addition in pure PCMs

To increase the thermal conductivity of organic phase change material (PCM), One-dimensional materials are often used as an additive due to their excellent thermal performance. Many experiments have shown that micro effects have a great influence on the thermal conductivity of composite materials. To clarify the micro effect, numerous molecular dynamics simulations (MD) have been carried out. Previous research has entirely overlooked the thermal conductivity changes of pure PCM in composite systems. Neglecting the thermal conductivity changes of pure PCM is unreasonable, as the mass fraction of nanoparticles is often small. We took paraffin wax (PW) with carbon nanotube (CNT) as an example, and successfully reproduced the phase transition of composite PCM. Then we optimized the details of simulating thermal conductivity, and two processes of replication and movement were taken to get a stable thermal conductivity. A disassembly of thermal conductivity based on heat flux was actualized to investigate the thermal conductivity of pure PCM in composite systems. We investigated the difference in thermal conductivities between solids and liquids and analyzed the underlying mechanism through vibrational changes. The change of thermal conductivity in solids is contributed by CNT itself and the structure of PW; the change of thermal conductivity in liquids is contributed by CNT itself and the interaction of CNT. Among these factors, structure change wouldn't always be beneficial. CNT always induces an axial enhancement of thermal conductivity in pure PCMs. At last, verification was carried out to prove the importance of structure. Our study brought a new view to understanding the behavior of thermal conductivity in composite PCM.

Theoretical study and physical tests on the influence of process parameters of needle on dispensing quality

Reasonable design and control the movement parameters of the needle of the piezoelectric needle-collision jetting dispenser is the key to ensure the stable and reliable of opto-electronic packaging. Existing studies just focus on the impact speed and assume that the needle moves at constant speed. Therefore, the effect of the actual needle movement on the stability of the dispensing quality was investigated, especially the effect of the rising speed on the droplet weight and the bubble content of the glue droplets. First, based on the movement process of needle, the fluid dynamics model of glue is established. Second, based on the independently developed piezoelectric needle-collision jetting dispenser, laser vibrometer is used to test the displacement and variable speed of the needle, which further verified the correctness of the analysis results and the feasibility of the research technology. Third, based on the actual motion and numerical simulation, the effects of rising speed and drive voltage on air suction, glue volume and bubble content of spray glue are analyzed. Finally, the theoretical results are verified by experiments, which shows that in order to ensure the weight of the droplets, the rising speed of the needle should be reduced and the drive voltage should be increased. In order to avoid the formation of bubbles in the droplets, the rising speed and drive voltage should be reduced. The findings in this paper can guide the design and control of jetting dispenser, which is used to meet specific industrial requirements.

Multi-objective optimization of pressure regulators in buildings’ HVAC systems

The control accuracy of the adjustable dynamic flow balance valve regulators is closely related to the energy consumption of the buildings' HVAC system. Therefore, optimizing the control accuracy of the pressure regulator plays an important role in reducing the energy consumption of the HVAC system and indoor cooling and heating comfort. In the study, the transient dynamics calculation method was used to simulate the movement process of the regulator diaphragm. The rebound force and fatigue life of the diaphragm are the optimization goals. An improved whale algorithm is proposed to optimize the Kriging model. The sensitivity analysis of the objective function surrogate model was carried out by the single factor analysis method. Based on the improved seagull algorithm, the multi-objective optimization of the diaphragm was carried out, and the corresponding MATLAB program was compiled. The optimized Kriging proxy model has higher fitting accuracy and smaller prediction error. The rebound force of the optimized diaphragm is reduced by 13.13% compared with that before optimization, and the fatigue life is increased by 87.89%. The dynamic characteristics and control accuracy of the adjustable dynamic flow balance valve after optimizing the diaphragm are verified by experiments. The maximum flow value is reduced by 2.03%, the transition time is reduced by 15.1%, and the stable flow value is closer to 20 t/h. This study contributes to the development of machine learning models with higher fitting accuracy and provides a new feasible design method for reducing energy consumption in buildings’ HVAC systems.

Historical Convergences and Region Making in Sultanate Gujarat

This article reflects upon the role of intra-, inter-, and trans-regional networks in the making of distinctive regional formations in the long fifteenth century. Through its focus on Gujarat, a region often seen as lying at the intersection of both maritime and overland trade routes, the article highlights the historical conjunctures that gave expressions to a distinctive regional identity in the fifteenth century. Using court-chronicles and texts produced by Sufi disciples and descendants in Gujarat, the article argues that by employing “convergence” as a conceptual tool, it becomes possible to explain how the processes of movement and circulation of people, goods, and ideas that had defined much of the Indian subcontinent resulted in creating distinct regional formations. Such distinctiveness was marked overtime through state-making, the use of specific vernaculars, the success of specific spiritual fraternities and other forms of cultural production. Locating historical convergences further allows us to break away from a linear understanding of the emergence of regional formations in the wake of the disintegration of the Delhi Sultanate, to instead focus on the simultaneity and continuity of larger political and socio-cultural processes.

Simulation analysis of rockfall movement characteristics with debris slope using Unity3D based on UAV remote sensing DSM: a case study of the G318 Highway on the Tibetan Plateau

Rockfalls on debris slopes pose a significant hazard to canyon roads on the Tibetan Plateau. In order to assess risks and develop effective engineering solutions, it is crucial to fully understand the characteristics and processes of rockfall movement. This research utilizes UAVs and three-dimensional (3D) laser scanners to capture images and data, while Pix4D is employed to create a high-precision 3D model from the collected data. Unity3D is utilized to analyze the movement characteristics and deposition positions of rockfall. Various movement characteristic indexes, such as velocity, acceleration, displacement, energy loss, and deposit position, are computed and examined for blocks with different shapes, sizes, instability types on the debris slope, and blocks composed of various slope materials and inclinations. The aim is to obtain insights into the specific movement mechanisms of debris slopes, which differ from conventional slopes. Field experiments have confirmed the effectiveness of the Unity3D simulation approach. Building upon this foundation, a high-precision 3D simulation model for the debris slope of the G318 Highway on the Tibetan Plateau is developed using Unity3D. This model is used to calculate the movement characteristics, energy variation, and deposition positions of rockfall. The findings are then compared with those of common models. The results demonstrate that the high-precision 3D simulation model computed by Unity3D provides more accurate and reasonable results compared to the common model. Moreover, the movement characteristics, energy variation, and deposition positions of rockfall on debris slopes exhibit specific characteristics. By employing Unity3D simulation analysis, a comprehensive understanding of the phenomena and behavior of rockfall on debris slopes can be achieved, enabling the proposal of more reasonable engineering protection measures.

Assessing the accuracy of modeling the tubbing erector manipulator mechanism in solidworks motion program

Purpose. To estimate the calculation error in determining the kinematic and dynamic characteristics of the UT62 tubbing erector manipulator mechanism movement. Methodology. Modern computer analysis methods are used, which are implemented in a number of computing complexes. Due to the task complexity, a mathematical model for the manipulator mechanism fragment, which is a hydraulic cylinder with two degrees of freedom, has been developed to estimate the error of computer modeling. This model is used as a test model. Findings. On the example of the model study, it is shown that when simulating the mechanism movement, errors in the calculations are possible due to incorrect problem formulation, as well as to the inaccurate settings of the modules for converting the initial data. Under these circumstances, it has been concluded that when the input link movement is specified as a vector, then when determining the kinematic and dynamic characteristics of the mechanism, it is necessary to use a cubic spline in the “interpolator” module. Originality. For the first time, the direct problem of the manipulator mechanism dynamics has been solved, which consists in determining the static and dynamic characteristics of the device according to the given motion law of its drives. It is noted that when the motion is specified in the form of smooth analytical functions, then there is a complete coincidence of the calculation results performed by the SOLIDWORKS MOTION program with those obtained by mathematical modeling. In addition, when the mechanism link input movement is modeled as a vector, which is formed from a discontinuous function, then the cubic spline used in the “interpolator” module provides smooth harmonic functions of the movement, acceleration and jerk processes. As a result of modeling the manipulator mechanism parameters, it turned out that it is not expedient to use more than 50 points of discrete time in the research. Thus, the errors in calculating the maximum power values of the manipulator motors do not exceed 20 % for the power hydraulic cylinder and 5 % for the hydraulic motor. Practical value. The proposed algorithm can be used to model the movement of complex mechanisms in machines.

DYNAMICS OF VIBRATION GRINDING WITH REGARD TO THE INFLUENCE OF SORTING MATERIAL ON ITS WORKING PARAMETERS

The general calculation model of the screen system was determined - the material is based on the study of the interaction processes between the sieve and the crushed stone that was on the screen. The selected model of vibration movement of loose material made it possible to determine the qual-itative and quantitative characteristics of the dynamic impact on the working body. The sorting process is presented as some orderly process of movement of a large number of different particles in a layer on a sieve. The main provisions for the calculation of the main parameters of the screen are formulated, which ensure the specified modes of the process of sorting the material and obtaining the appropriate fractional composi-tion of crushed stone. The prerequisite for choosing the calculation scheme "screen-sieving material" is the determination of the vibrational movement of a material particle along a vibrating hard surface inclined to the horizon at an angle that carries out rectilinear oscillations at an angle to the plane of the screen. At the same time, weight, friction force and normal reaction act on the particle. The proposed model made it possible to determine the speed of transportation in the case when the screening screen performs a circular motion, which is the addition of two independent oscillations with different amplitudes and frequencies. The sorting process is significantly affected by the probability of grains passing through the holes of the sieve. This prob-ability depends on the size of passing particles, the dynamic parameters of screen vibrations, the design of the sieve, the shape of the sieve openings, the coefficient of the live section (the ratio of the area of the openings in the light to the total area of the sieve. The average speed of passage of particles through the sieve is determined by the frequency of contact of particles with the surface and the ratio of particle sizes and the hole. The frequency of particle contact with the sieve is affected by the amplitude and frequency of vibrations of the sieve surface. The probability of a particle passing through the sieve hole during one collision can be estimated based on the calculation charts.

MODELING AND OPTIMIZATION OF THE PROCESSES OF MOVEMENT AND ACCELERATION OF THE OVERHEAD CRANE TROLLEY IN THE MODE OF DAMPING UNCONTROLLED LOAD OSCILLATIONS

The paper deals with the modeling and optimization of the processes of movement and acceleration of a bridge crane trolley in the mode of damping uncontrolled oscillations of the load. For the dynamic system of a flat pendulum with vibration damping, which describes the oscillations of a bridge crane load on a flexible rope suspension in a separate vertical plane, it is proposed to use third-order time splines that model the motion and acceleration of the load suspension point in the horizontal direction of the trolley's movement. To determine the time dependence of the angle of deviation of the crane from the gravitational vertical, it is proposed to use the methods of classical calculus of variations (Euler-Poisson equation), which allow optimizing (minimizing) the value of this angle in the process of accelerating a trolley with a load suspended from the ropes of an overhead crane. An analytical solution to the problem of damping residual uncontrollable oscillations of the overhead crane load, which usually occur after full acceleration or braking of the load suspension point on the trolley, is obtained. To derive the dependencies, an analytical approach was used to calculate the value of the angle of deviation of the overhead crane's cargo rope from the gravitational vertical, depending on the acceleration and displacement of the load suspension point. The problem of loosening of a load moved by an overhead crane is considered and solved in a new way that allows to completely avoiding pendulum spatial oscillations of the load on a rope suspension. The mathematical apparatus of linear algebra (Kramer's rule, in particular) is used, which allows us to establish analytically the law of time motion of a rope with a load, the angle of deviation of which from the vertical takes minimum values in the process of acceleration of the cargo trolley.

Price Correction and Its Justification in Behavioral Finance with The Jabalameli Chartical Method and Its Adaptation to The Omnipotence Defense Mechanism

All human beings, from the moment of birth to the moment of death, without any exception, will face all kinds of bitter and sweet events, which are sometimes chosen and sometimes out of the individual's will, but either by choice or imposed, These events will have an effect on the nervous system. Because after a person enters this world from the safe environment of his mother's womb, until the moment of death, he must know his complex world and always make conscious and unconscious efforts to survive. Being according to the customs of the society or in other words becoming the same colour as the congregation is one of the most common methods of a person in order to maintain his position in society in order to ensure his survival. One of the methods of observing this behavioural phenomenon in humans is the behaviour and trading decisions of a person in the face of the price movement trend in the financial markets based on financial-behavioural. The present study is a review of the concept of price correction and its justification in behavioural finance using the Jabal Ameli chartical method, which is descriptive-analytical, and the information data required for it is collected by library and document research methods. The obtained results indicate that entering the price movement process at any point of the financial market without taking into account sufficient skill in managing it is one of the most fundamental reasons for the formation of correction and such transactions and correction can be achieved. He considered it a kind of defence mechanism to relieve the stress of the nervous system

Investigation of labour intensity and duration of the assembly processes of structural covering blocks

The article considers an approach to determining the labor-intensiveness and duration of consolidation processes during the installation of structural blocks of the covering, which is caused by atypical structural and technological solutions. The relevance of this work is the need for a qualitative analysis of methods for calculating the labor intensity and duration of technological processes when justifying and making decisions regarding the organization and mechanization of assembly processes.
 Modern technologies of installation of structural blocks of coatings are analyzed. The analysis of labor costs was carried out for the option of using load-lifting assembly modules to reduce the specific share of the use of heavy crane equipment at the construction site. In comparison, the method of installing a structural coating using heavy crane equipment and load-lifting assembly modules is considered.
 To ensure the principle of comparison of options, the processes of column installation, stand installation, block consolidation, block installation, and installation and movement of a crane or assembly lifting and gathering modules are included in the consideration. All calculations were performed in tabular form according to the formula of the integer normalization method. Based on the results of the study, all the components of the labor intensity and duration of the processes were determined, on the basis of which the schedules of the consolidation and installation of the SBP blocks were built.

ASSESSING THE STATE OF THE ALVEILAR MORPHOTYPE IN PLANNING AND CARRYING OUT ORTHODONTIC TREATMENT OF PATIENT WITH INFLAMMATORY PERIODONTAL DISEAS ES

Aim: to assess the state of periodontal tissues when planning and performing controlled orthodontic movement of crowns and roots of teeth using the overlay of computed tomography on 3-D visualization of the process of movement of dentition in patients with inflammatory periodontal diseases.
 Methods: Based on the inclusion and non-inclusion criteria, the study involved 80 patients aged 25-35 years, who were divided into 2 groups - control (with clinically healthy periodontium) and main (with chronic generalized periodontitis) for orthodontic treatment of dentoalveolar anomalies. Orthodontic equipment for the comparison groups was identical (aligners, vestibular and lingual braces with passive self-ligation). Prior to the start of the orthodontic program, the alveolar morphotype was determined by CT of patients superimposed on the program for digital modeling of the future result; the optical density of the alveolar bone was estimated in Hounsfield units (HU). Clinical indicators for assessing the condition of periodontal tissues and after completion of the orthodontic program in the comparison groups.
 Results: After the completion of orthodontic treatment, patients of group 1 had a lower number of periodontal complications - 42% versus 54% in group 2, with initially normal periodontium with a thin alveolar morphotype; 18% and 23% - with a thick alveolar morphotype. The best results were noted in the aligners subgroup - 16% and 18% for groups 1 and 2, respectively; the worst - in the subgroup with lingually fixed braces - 50% and 55%, respectively. The most common periodontal complication was tissue recession. Thanks to the predictive planning of the assessment of patients' computed tomograms superimposed on the program of digital modeling of the final result after the displacement of teeth, a positive result of orthodontic treatment was obtained and the risk of negative impact of the orthodontic program on both intact periodontal tissues and damaged periodontium was minimized.
 Conclusions: The new ability to control the state of the alveolar ridge bone using 3-D visualization of tooth movement with CT overlay increases the efficiency of orthodontic treatment planning by 40%, ensuring a minimum of side effects and complications.

Identity and elites in developmental politics: a case study of the “Gorkha” and “Gorkhaland” movements in the eastern parts of India

ABSTRACT This article draws attention to the “Gorkha” as a constructed identity, given or adopted by Nepali-speaking community. The idea of “Gorkha” in general and the demand for the territory of “Gorkhaland” of India have remained an elitist project, and the employment of this idea/term “Gorkha” has been a political instrumentalization that failed to bring any form of development. The period of 1980s gave rise to the “Gorkhaland” movement in India for its subjugation and alienation, which sparked questioning about the identity of the Gorkha in Indian politics. The question arises: Why Nepali people are mobilized as “Gorkha” in its history? How is the “Gorkhaland” movement in India a developmental problem in contrast to ethnic politics? This paper is divided into two parts, such as (1) “Gorkha” and its origin in general and (2) Indian “Gorkha” and the “Gorkhaland” demand. The process of such movement led by elites brings both domestic and international attentions due to cross border and regional politics. This paper uses a thematic approach in analyzing the leader’s role in relation to the last Shah King, a recruitment policy of colonial British raj, and legitimization process by the “Gorkha” leaders in the “Gorkhaland” Movement.

Value equilibrium analysis based on the New Theory of Value. I

The (traditional) labor theory of value, founded by Smith with the basic axiom that labor determines value, and supplemented and improved by Marx with the axiom that labor creates surplus-value. Neoclassical economics newly studied the utility theory of value, but it abandoned the traditional labor theory of value and theory of surplus-value. Under the basic axiomatic system analogous to theoretical mechanics, the above three theories of value has been included and developed by the new theory of value, which established the value complex variable function including three basic quantities of quantity, quality and time, as well as labor value, use-value and surplus-value. Starting from the value complex variable function, with the mathematical methods of Euler equation and Euler formula, this paper conduct a thorough and comprehensive analysis on the theory of value, under satisfactions of Marx’s first and second laws, focusing on value equilibrium by giving the mathematical explicit expressions of both value equilibrium function and price equilibrium function in various forms applicable to the general commodity economic movement process, so as to prove the existence and stability of the extremum solutions to the corresponding functions.

Interactive Simulation of Realistic Fluid Movement Based on SPH Method

With the continuous progress of computer simulation technology, fluid simulation has been developed rapidly, and it has beeen widely used in many fields, especially in engineering compution, game and special effects in movie. Nevertheless, with the increasing requirements of fidelity of the motion and interaction of subjects, fluid simulation requires more realistic simulation results. However, the motion of real fluid and objects is often difficult to be expressed by simple process, which can only be realized by the physical laws in the real world. Physical-based fluid simulation is one of the most challenging research issues due to its complexity in theory and computations. Among numerous fluid simulation models, Smoothed Particle Hydrodynamics (SPH) based fluid simution is the most widely used meshless method to simulate the realistic fluid motion. As a simple and flexible method, SPH partical characteristics make it naturally suitable for fluid simulation modeling and feasible to deal with many fluid simulation computation problems in a robust and stable way. The SPH basic principle, kernel function, discretization scheme and boundary treatments are introduced. The fluid movement is solved by SPH method in accordance with Navier-Stokes equations. The accuracy and stability of the fluid solution equation was improved by correcting the pressure and velocity fields. Secondly, the water surface was modeled and the rendering speed of the fluid surface was optimized by simplifying the fluid particles calculation. The SPH model is developed to simulate impulsive wave generated by dam-break and high speed landslide. It shows the model can simulate the movement process of the fluid fragment and coalescence, and available to simulate the blood, volcanic explosion and tsunami propagation.

Echoing Syari'ah in City Spaces: The Framing Process and Political Mobilization of the Islamic Movement in North Sumatra


 This article discusses the Islamic political movement in fighting for sharia as an ethic of life in urban areas in Indonesia. In a more detailed manner, this article explores the idea of sharia as the main ingredient in the framing process and explores the movement's strategy to resonate with this frame, which then opens up opportunities for the formation of a wave of support for serial movement actions in Medan, North Sumatra. With the framing model in social movement studies, the data was collected from observations and interviews with several movement actors, and several supporting documents. This study found that the idea of this movements such as “Negara Kesatuan Republik Indonesia Bersyari’ah” (Indonesia Nation State based on Sharia) which is close to the social psychology of the masses met with the right events to generate great support for the movement. The ability of the elites to concoct the movement ideas, and the management of social media to spread such framing, made a mass wave of supporters strengthen. The struggle for sharia in the public space played by the movement here basically does not have a clear political agenda unless, temporarily, it is used only in electoral momentum, resonating as an expressive channel of the defeat against other groups in controlling the city's political economy space. Here, I argue that the study of ideology in social movements requires an expansion of dimensions that can explain more fully why a movement immediately grows or shrinks briefly or lasts a long time.
