Электростатическая теория селективности ионообменников
Authors: Шапошник Владимир Алексеевич
Published: March 2020

Ионообменники являются супрамолекулярными веществами, в которых сочетаются прочныековалентные связи (hard chemistry) со слабыми ионными и водородными связями (soft chemistry).Ионные связи в ионообменниках ослаблены гидратацией противоионов и фиксированных ионов. Во-дородные связи образуются между их гидратными молекулами. Элементарный транспортный актионного обмена заключается в разрыве слабых связей. Задачей настоящей работы было определениетипа связи, определяющей селективность ионообменника.Для определения энергии ионных связей был применён интегральный вид закона Кулона.Используя допущения Полея были рассчитаны энергии электростатического взаимодействия фикси-рованных ионов с противоионами. Установлено, что время удерживания катионов щелочных метал-лов является положительной экспоненциальной функцией энергии энергий электростатического при-тяжения противоионов фиксированными ионами. Коррекция параметров электростатического взаи-модействия ионов была проведена неэмпирическими методами квантовой химии.Для определения общей энергии разрыва связей противоионов с фиксированными ионами(энергии активации) была измерена температурная зависимость электропроводностей ионообменныхмембран контактно-разностным методом. Энергии водородных связей были рассчитаны по разностиэнергий активации и энергий электростатического притяжения противоионов фиксированными иона-ми. В результате было установлено, что энергии элементарного транспортного акта в ионообменни-ках для однозарядных ионов определяются преимущественно водородными связями, а для противо-ионов более высокого числа зарядов кроме водородных связей существенную роль играют ионныесвязи, Основным результатом исследования является доказательство определяющей роли электроста-тического взаимодействия (ионных связей) в избирательности ионообменников.

Social Safety Net Programmes and its Impact on Livelihood: A Case Study of Bangladesh
Authors: Рахман Саифур
Published: March 2020

Bangladesh has been implementing social safety net programmes (SSNP) to protect vulnerable groups of people. Old Age Allowance (OAA) and Allowances for the Widows, Deserted & Destitute (AWDD) are two unconditional cash transfer programmes under the SSNP for vulnerable old age people and women, respectively. The impact of these programmes are examined in two upazilas (sub-districts) of the poorest district of Kurigram: Roumari upazila, which is comparatively better off, and Rajibpur upazila, which is the poorest. Natural disasters and remoteness are the reasons for this region’s vulnerability. In-depth interviews were conducted with twenty recipients to understand the implications of the allowance’s’ impact on their livelihoods. The findings reveal that the allowance contributes to necessary food consumption and acts as a coping mechanism during natural shocks. However, asset building and resource diversification are important to ensuring a sustainable livelihood. A small cash transfer is not enough for recipients to save and diversify their income growth. The allowance has minimal or no impact on the mediation of other capital assets like access to natural resources or social capital. Working-age recipients rely heavily on agricultural-based activities, but they do not own the land they farm. SSNP does not offer suitable cultivation practices, such as training that could fortify living capabilities or, sufficient resources to encourage career development. Additionally, a number of the beneficiaries are beyond working age. Aside from various factors like malpractice and usury, cash transfer systems have an adverse impact on OAA / AWDD, which reduces the value of allowances. The allowances from SSNPs provides a minimum support for survival but not enough to generate income and asset building capabilities. Hence, it is hard for beneficiaries to achieve a sustainable livelihood.
Использование краудфандинга в решении социальных и культурных проблем сельских территорий России
Authors: Латышева Александра Николаевна
Published: March 2020

В статье дано определение краудфандинга и показано, как он может быть использован для решения социальных и культурных проблем сельских территорий. В академической литературе краудфандинг рассматривается, преимущественно, как новый бизнес-инструмент и способ привлечения инвестиций. Однако бÓльшая часть проектов, которые создаются на краудфандинговых площадках, связаны с культурными и социальными инициативами. В статье изучается распространение социальных краудфандинговых проектов; дается ответ на вопрос, являются ли они более или менее успешными, чем проекты на других площадках; а также рассматривается география проектов, чтобы понять, не является ли это явление сугубо столичным. В качестве объекта изучения выбраны социальные краудфандинговые проекты, связанные с поддержкой сел. Эта тема оказалась достаточно востребованной на крауд-площадках, и при этом не связанной напрямую с основными пользователями краудфандинга – жителями крупных городов. Изучение проектов этой тематики позволяет показать, как краудфандинг может работать для привлечения финансирования к местным инициативам. Для исследования отобраны более двухсот проектов, стартовавших с 2012 по 2017 гг. на платформах Boomstarter и Planeta.ru. Поиск осуществлялся по ключевым словам: «село», «сельский», «деревня», «деревенский». Проекты, связанные с поддержкой сел, показывают более высокий процент успешности, чем в среднем по платформам, в рамках выборки нет заведомо более или менее успешных тематик, а их география охватывает 54 субъекта из 85. Анализ показал, что успешно реализовать проект данной направленности возможно в различных тематиках, в разных регионах. Благодаря краудфандингу местный проект может получить финансирование от максимально широкого круга лиц, никак не связанных с регионом. Это даёт краудфандингу преимущество над другими инструментами, например, над Программой поддержки местных инициатив (ППМИ).
Политизация экологического дискурса в Архангельской области на примере строительства мусорного полигона около станции Шиес
Authors: Чмель Кирилл Шамилевич , Климова Айгуль Маратовна , Митрохина Евгения Михайловна
Published: March 2020

Экологическая повестка заняла центральное место как в политической, так и в социальной формах протеста в России в 2018–2019 гг. Принятие решения об открытии мусорного полигона около станции Шиес в Архангельской области вызвало не только закономерное недовольство жителей политикой региональных элит, но и укрепило положение экологического протеста по всей России, прокладывая путь дискурсивному и фактическому политическому участию. Более того, кейс мусорного полигона около станции Шиес не является исключением, характеризующим российский контекст. Природа сегодня выступает не только объектом, но и субъектом политики во многих странах. Что позволяет сугубо социальному вопросу о состоянии окружающей среды и ее влиянии на повседневную жизнь людей приобретать черты политического обсуждения, требующего конкретного решения? Цель статьи – определить и показать механизмы политизации экологического дискурса в России на примере ситуации, связанной с открытием мусорного полигона около станции Шиес в Архангельской области. Мы покажем, как определенное политическое решение властей, принятое вне публичного обсуждения и при игнорировании конкурирующих дискурсов, привело к доминантному дискурсивному конструированию экологической проблемы как политической. Эмпирической базой исследования послужили 19 полуструктурированных интервью с жителями Архангельской области. Методологией исследования выступает дискурс-анализ, в основе которого лежит аргументативная традиция. Мы сфокусируемся исключительно на аргументативных конструкциях – ссылках на факты, нормативно-правовые акты, риторических приемах для обоснования мнения, – которые субъекты используют для доказательства правоты своей позиции. Покажем, что политизация дискурса и высокая политическая мобилизация граждан произошли за счет трех основных механизмов, которые сработали одновременно: оценка принятого властями решения как нелегитимного, как несправедливого, а также выделение определенных политических лидеров в качестве ответственных за эту несправедливость.
ALGERIAN NORTHWESTERN SEISMIC HAZARD EVALUATION BASED ON THE MARKOV MODEL
Authors: Dahmoune Badreddine , Mansour Hamidi
Published: March 2020

The main aim of this paper is to develop a markovienne model for the evaluation of seismic hazard in the north-western part of Algeria. A region that accommodates from moderate to strong seismic activity (ML ≥ 2.5). This work is an attempt to conceive a stochastic model of the earthquake occurrences in order to assess the seismic hazard based on the use of a discrete time Markov chain with a finite state model. The presented model is applied on a complete data sample comprising most of the earthquakes that occurred in the Algerian northwestern area located between latitudes (34°N, 37°N) and longitudes (2°W, 3°E) since 1928 up to now (2018). The Markov chain is built over a homogeneous and completed catalogue, then the transition probability matrix of the chain is used to simulate the occurrences of the earthquakes in the coming decades. The results are compared to a classic Poisson model.
SIMULATION OF CO2 INJECTION IN A DEPLETED GAS RESERVOIR: A CASE STUDY FOR UPPER MIOCENE SANDSTONE, NORTHERN CROATIA
Authors: Lekić Amalia , Jukić Lucija , Arnaut Maja , Macenić Marija
Published: March 2020

Carbon capture and storage (CCS) technology is a beneficial greenhouse gas mitigating strategy carried out in the last 20 years. Depleted gas reservoirs are promising candidates for the storage of carbon dioxide (CO2). Therefore, a depleted gas reservoir in the Upper Miocene sandstone located in Northern Croatia was taken as an example. The purpose of this study was to compare CO2 storage capacity obtained with two analytical equations to total storage capacity obtained through the simulator, in order to validate the equations. The first equation takes the average reservoir pressure and available production data into account, while the other one is more general and includes produced volume, CO2 density and formation volume factor of the original fluid. The tools used for these calculations were Schlumberger PVTi software, in which the equation of state was obtained, and ECLIPSE (E300 Module) which is a reservoir engineering simulator used for reservoir behaviour prediction. The results conformed analytical solutions, indicating that, depending on the depth, the mass of the CO2 that can be injected is twice as big as the mass of CH4 produced. The results of analytical solutions, 16.7 × 106 m3 and 14.6 × 106 m3, are in accordance with the results obtained by the simulation of CO2 injection in depleted reservoirs - 16.2 × 106 m3. Based on this, a conclusion is derived that these analytical solutions can be used as a first approximation of injection in a depleted gas reservoir.
COMBINED UTILIZATION OF RED MUD AND MECHANICALLY ACTIVATED FLY ASH IN GEOPOLYMERS
Authors: Mucsi Gábor , Szabó Roland , Rácz Ádám , Kristály Ferenc , Kumar Sanjay
Published: March 2020

This paper focuses on the investigation of the co-utilization of two major industrial waste materials, power station fly ash and red mud. Experimental studies were carried out to establish the correlation between the physical properties of a geopolymer product and a mixture composition. The effect of mechanical activation and the red mud dosage on the geopolymerisation was investigated. Geopolymerisation of mechanically activated fly ash has been carried out with various proportions of red mud ranging between 0–30 % by weight. The compressive strength of fly ash based geopolymer increased until 15% of red mud addition. The optimal red mud addition in fly ash geopolymer was determined. The influence of red mud on phase composition and chemical bonds of the resulted geopolymer were determined by XRD analysis and FTIR studies. Due to the geopolymerisation reactions, new phases like hydroxy-cancrinite, faujasite and thenardite appeared in the product.
THE INFLUENCE OF GEOLOGY AND ORE DEPOSIT OCCURRENCE CONDITIONS ON DILUTION INDICATORS OF EXTRACTED RESERVES
Authors: Petlovanyi Mykhailo , Lozynskyi Vasyl , Saik Pavlo , Sai Kateryna
Published: March 2020

The development of iron-ore deposits is accompanied by the excavation formation of considerable dimensions in the underground space and to ensure high technical and economic indicators of extraction, especially when developing high-grade iron ore, it is necessary to take into account the nature of the geological structure of the massif on the indicators of their dilution. It is established that when the chambers are worked out on a junction with hanging wall waste, the indices of ore dilution with the adjacent strata are 1.7 times higher than on a junction with the foot wall of the deposit. The tendencies and causes of variability of volume of extracted ore dilution with the adjacent strata in different geological structure parts of the ore deposits are revealed, the ore basin across the pitch is characterized by a general evolving trend of the rock strength of the hanging wall and ore basin angle of incidence decreasing and increasing the thickness of the deposit from the northern side to the southern one. It has been established that the concentration of hanging rocks caving and extracted ore dilution indices is enhanced by changing their morphological composition, reducing the strength and stability of these rocks, reducing the ore basin angle of incidence, and increasing the ore deposit thickness. The obtained results allow us to lay the foundations for optimizing the parameters of the development system and the rational procedure for breaking up ore reserves in the chambers under the changing mining and geological conditions of field development.
INSIGHT INTO SEISMIC REFRACTION AND ELECTRICAL RESISTIVITY TOMOGRAPHY TECHNIQUES IN SUBSURFACE INVESTIGATIONS
Authors: Akingboye Adedibu Sunny , Ogunyele Abimbola Chris
Published: March 2020

Geophysical subsurface investigations use the principles of physics to unravel intrinsic Earth’s subsurface features and nature of the underlying geology. Over the past two decades, the use of Seismic Refraction Tomography (SRT) and Electrical Resistivity Tomography (ERT) for subsurface investigations has greatly improved the quality of acquired data for two- and three-dimensional (2D and 3D) surveys. SRT employs more shotpoints and receivers than the conventional seismic refraction for its imaging technique. ERT uses automated multi-electrode array systems to improve the confidence of large and dense data collection. SRT and ERT techniques use powerful inversion algorithms to achieve high resolution subsurface inversion models for resolving subsurface characteristics and geological conditions over a complex and larger area that may be difficult with the use of their conventional methods. The 2D and 3D inversion models (tomograms) generated from the field data sets of these techniques efficiently ameliorate inaccurate subsurface boundaries and structural delineation with higher depth resolution, especially the 3D inversion models for areas of complex geology. These state-of-the-art techniques have extensively been used for groundwater, environmental, engineering and mining investigations among others. This study provides insight from theories to data inversion techniques for the known tomography techniques (SRT and ERT) in use for subsurface investigations.
Do We Need a Criminalistic Characterization of a Crime in the Criminalistic Methodology?
Authors: Ishchenko P. P.
Published: March 2020

The paper deals with the essence of criminalistic characterization of the crime, its necessity and role in the criminalistic methodology. The attitude of the scientific community to this scientific category for half a century of its existence has undergone dramatic changes: from enthusiastic exaltation as a universal means of solving crimes to a useless “phantom” of criminalistics. However, despite criticism from a number of highly eminent scholars, criminalistic characterization of the crime has not disappeared from academic intercourse and has firmly enshrined its role in criminalistic methodology. The paradox is explained by its systemic need in the arsenal of this section of criminalistics. As the only acceptable indication of the empirical knowledge of the crime and the ways of its disclosure developed by criminalistics, the criminalistic characterization of the crime not only amounts to core of individual forensic techniques, but also defines the structure of the entire forensic methodology as a branch of the science. Attempting to abandon it leads to the emergence of various substitutes that are similar in content, but less successful with regard to terms. For these reasons, the criminalistic characterization of a crime cannot be rejected by forensics despite any criticism. It seems that the “phantom” is not the very idea of criminalistic characterization of the crime, but the method by which it was “filled.” A systematically necessary and successfully named design was unsuccessfully methodologically connected by its creators with statistical measurements of correlation dependencies between the main criminalistically significant elements of a crime. However, such measurements are unsuitable for a specific investigative methodology. The “filling” of criminalistic characterization with relevant information concerning criminal activity should be provided by the totality of methods available for empirical sciences without being limited to statistical measurements of the links between its elements.
Field Theory in Practice
Authors: Omaña José Méndez
Published: March 2020

The aim of this paper is to present K. Lewin’s Field Theory in practice, applying it to evacuation simulations. The construction of the field is discussed from the scratch in order to define the psychological space of a social event. Then, we illustrate the interplay of the physical and the psychological aspects of a mathematical model of human behavior presenting and discussing evacuation simulations of one event. At first we simulate the physical situation and then we calculate an evacuation time applying an elementary microscopic model. An empirical plausibility control is presented. When we apply mathematical modeling or cybernetic methods to social sciences we are said to be careful. Nevertheless, a social event might be considered, on a natural way, as a set of time series, from the point of view of statistics. In this paper we restrict ourselves to introduce probabilities of random variables associated to the physical and the psychological space and define a measure for the evacuation simulation: The entropy of the event, merging the physical and the psychological spaces.
Experimental study on the influence of background music on pedestrian movement in high densities
Authors: Zeng Guang , Schadschneider Andreas , Zhang Jun , Song Weiguo
Published: March 2020

It is interesting to investigate the effect of background music on pedestrian movement. This paper investigates the properties of crowd motion with external rhythms. With rhythm, pedestrians stop more frequently than without any rhythm. The stopping also increases with the increment of the tempo. Velocity and flow with rhythms are lower than that without any rhythm at high densities due to the more frequent stopping. Stepping behavior analysis shows that the step frequency with rhythms is smaller than that without any rhythm, especially at high densities. Dynamic coordinated behavior is weakened by music, which also affectsthe stepping behavior. Our study will be helpful for understanding the effect of background music on pedestrian movement.
Investigation of pedestrian evacuation scenarios through congestion level and crowd dang
Authors: Feliciani Claudio , Nishinari Katsuhiro
Published: March 2020

In this paper, we present two quantities aimed at numerically describing the level of congestion and the intrinsic risk of pedestrian crowds. The congestion level allows to assess the smoothness of pedestrian streams and recognize regions where self-organization is difficult or not possible. This measure differs from previous attempts to quantify congestion in pedestrian crowds by employing velocities as vector entities (thus not only focusing on the absolute value). The crowd danger contains elements related to congestion, but also includes the effect of density, consequently allowing to asses the risks intrinsically created by the dynamics of crowds. Details on the computational methods related to both quantities are described in the paper and their properties are discussed. As a practical application, both measures are used to investigate supervised experiments where evacuation (or similar conditions) are considered. Results for small room sizes and limited number of pedestrians show that the crowd danger distribution over the space in front of the exit door has similar patterns to typical quantities used in the frame of pedestrian dynamics (density and flow) and symmetrical shapes are obtained. However, when larger scenarios are considered, then congestion map and crowd danger become unrelated from density and/or flow, showing that both quantities express different aspects of pedestrian motion.
Effect of architectural adjustments on pedestrian flow at bottleneck
Authors: Wang Jianyu , Ma Jian , Lin Peng
Published: March 2020

In the last decades, a series of terrible accidents happened within pedestrian crowds, which makes crowd dynamic a significant issue to be investigated. Literature reviews show that pedestrian flow presents different features within different architectural layout. In this paper, pedestrian movement properties at bottleneck are studied by carrying out series of experiments under laboratory condition. The influence of door sizes and exit locations on pedestrian crowd flow is investigated. It was found that larger door width resulted in shorter evacuation time and faster flow rate. By comparing the fundamental diagram among crowd evacuation, the average velocity increases as the width increases under the same density condition. Interestingly, the influence of the boundary layer, as well as the effective width on pedestrian crowd dynamic, was clearly observed. Our results suggest that the combination of exit width and location resulted in a synergistic effect, but the exit widths gradually became the most important factor influencing the flow rate.
Experimental Study on Variation Strategies for Complex Social Pedestrian Groups in Conflict Conditions
Authors: Zou Xiaolei , Qu Xiaoyi , Xu Ruihua
Published: March 2020

The paper concentrates on an experimental study of the variation strategies of complex social pedestrian groups in conflict conditions. We tracked the trajectories of group members and analysed the configuration of both the complex group and its subgroups when the groups walked through a narrowing passage, passed by an obstacle or faced counter flows. We summarized the variation strategies of complex groups when they faced these conflict conditions. The effect of groups on the crowd was also studied. It was found that groups could have significant effect on self-organization of the crowd. The results in the paper could be applied in modelling pedestrian group decision and behaviour and analysing crowd dynamics.
Measuring social influence and group formation during evacuation process
Authors: Balboa Adriana , Cuesta Arturo , Alvear Daniel
Published: March 2020

Evacuees are likely to respond and move forming groups. However specific data about grouping is generally unavailable and the relationship between response and movement times and specific groupings are unknown. Using a simple method, we measure behavioural cohesion of occupants during evacuation processes. The case study involves using the method in a bus station, a sport centre and a library. Results suggest that proximity (visual/verbal contact) is an important factor but not decisive in the formation of evacuation groups. Social ties and whether occupants share a target and/or an activity before the alarm are also deemed to be important factors. This study provides an exciting opportunity to advance our knowledge of social influence and group formation during evacuation.
Modelling and Simulation of Urban Mobile Agents for Analyzing Mixed Flows in Urban Pedestrian Space
Authors: Kaneda Toshiyuki , Shohmitsu Masahiro , Sasabe Wataru , Liu Yuanyuan
Published: March 2020

Since the 1990s, complex systems research has been developing agent simulations to explain the phenomena observed in urban spaces. In recent years, agent-based modelling has often been employed to successfully simulate pedestrian behaviour. In such studies, explanations using pedestrian counter flow phases have appeared sporadically. Most state-of-the-art models, however, do not generally consider mobile agents other than pedestrians or counter flows in at least two directions. In this paper, we consider agents such as pedestrians, vehicles, wheelchairs, bicycles and so on in urban pedestrian space (UPS), which we call urban mobile agents (UMAs). The aim of this research is to develop a simulation platform to support urban simulation research. The models of rule-based UMAs that we have been developing are used to analyze the micro-meso behaviours of the mixed flows in UPS. The content of this class of agent includes the pedestrian agent as per the simplified agent simulation of pedestrian flow (sASPF) rules as well as the vehicle agent and bicycle agent in the UPS, including a wheelchair agent in the coming research. Using these models, we explore the following approaches: (a) theoretical analyses of phase transitions such as laminar flow formation or blockade of pedestrian counter flows, with clarification of the relationship between the degree of pedestrian global density and the bias of the diagonal stepping probability, which is the right or left selection probability of avoidance behaviour; (b) the implementation of obstacle avoidance rules in the sASPF pedestrian agent model, and their comparison with published evacuation experiment results, so as to evaluate the performance of the obstacle avoidance function; (c) the development of a vehicle agent model to simulate pedestrian-vehicle mixed flow at a crossroads assuming a disaster scenario; (d) the development of a bicycle agent model by extending sASPF rules; and (e) consideration of a conceptual framework for interaction fields representing heterogeneous agent mixed flows, including vehicle, bicycle, pedestrian and wheelchair agents.
Analysis on Alighting and Boarding Movement Laws in Subway Using Modified Social Force Model
Authors: Chen Feng , Gao Yongxin , Wang Zijia , Liu Yan
Published: March 2020

This paper presents a multi-agent simulator based on social force model to simulate each passenger’s boarding and alighting behavior both in a train and on a platform seamlessly. Passengers can be divided into three types: to board, alight and stay in train. They have different individual attributes and follow different walking rules. Due to the characteristics of subway environment and passengers' behavior in boarding and alighting, some adjustment and improvement were made to the basic social force model: (1) In some cases during the process of boarding and alighting, the driving force targeting to destination needs to be doubled, and the repulsion force between two agents needs to be reduced. (2) Passengers who stay in the train show quite different movement from the usual pedestrian. They usually want to remain still, unless they are in front of the door. To describe their behaviors, we introduced a tangent detour force. The scope of the interaction between agents is extended and some passengers out of the visual field also should be counted. (3) Divide the repulsive force between an agent and an obstacle into the frontal force and convex corner force. These two forces have different spheres of influence and calculation methods. The agents could exhibit reasonable intelligence and diversity during alighting and boarding.
Movement Characteristics of Processions
Authors: Polichronidis Petros , Schreckenberg Michael
Published: March 2020

Processions are a scientifically not much investigated traffic system. Recent studies found that the first participant in the Cologne Rose Monday parade has a remarkable higher travel time than the last participant. The velocity profiles of the participants are explained by the constant moving vehicle driving ahead of the parade leaving the pathway and partly due to a spatial contraction of the parade during the procession. This contribution compares the traffic kinematics of the Cologne Rose Monday parade in Germany with other processions (Schuetzenausmarsch Hanover 2017, Niederrheinischer Kinderkarnevalsumzug 2018). The kinematics of these processions were analysed based on GPS data from participants. Their kinematics differ from those of the Cologne Rose Monday parade. In general, the observations depend on the size of a procession, the length of its pathway, the composition of the procession and especially on the catching up behaviour, of the participants, when gaps occur in front of them. Furthermore, we examine the influence of the pathway on the traffic flow. This can be used to choose a parade’s pathway avoiding flow reducing infrastructure characteristics like traffic area transitions, narrow curves etc. In summary, this work extends the understanding of the kinematics of processions. It can serve as a basis upon which the parade’s movement can be predicted and so the duration of such events can be estimated better.
Noise-Induced Stop-and-Go Dynamics in Pedestrian Single-file Motion
Authors: Schadschneider Andreas , Tordeux Antoine
Published: March 2020

Stop-and-go waves are a common feature of vehicular traffic and have also been observed in pedestrian flows. Usually the occurrence of this self-organization phenomenon is related to an inertia mechanism. It requires fine-tuning of the parameters and is described by instability and phase transitions. Here, we present a novel explanation for stop-and-go waves in pedestrian dynamics based on stochastic effects. By introducing coloured noise in a stable microscopic inertia-free (i.e. first order) model, pedestrian stop-and-go behaviour can be described realistically without requirement of instability and phase transition. We compare simulation results to empirical pedestrian trajectories and discuss plausible values for the model’s parameters.
Tsunami evacuation facility choice behavior model in flat area and rias area considering possibility to remain at home
Authors: Yoshihara Hiroyuki , Kishimoto Tatsuya
Published: March 2020

The tsunami associated with the Great East Japan Earthquake that occurred on March 11, 2011 caused enormous damage to the coast of the Pacific Ocean. Since the occurrence of the Great Earthquake, it is urgent to develop tsunami evacuation countermeasures against the great tsunamis caused by the large earthquake that is expected to occur in the future in the country and coastal municipalities. In this study, we used logit model to estimate each parameters about the relationship between evacuees and buildings in flat area and rias area by using the evacuation behavior survey data of the Great East Japan Earthquake in 2011. The estimated results show that “whether the evacuation destination is home or not” is important when people choose the tsunami evacuation destination. Moreover, by comparing the moving in flat area and in rias area the difference between them becomes clear. By using these models, it enables to estimate the home selection probability in flat area and rias area.
Determination of pedestrian’s personal space in mass religious gatherings - A case study of Kumbh Mela
Authors: P M Aparna , Sobhana Karthika , Verma Ashish
Published: March 2020

Personal space can be defined as the physical distance between two individuals in a social environment. It varies from person to person depending on culture and context and there are significant individual differences too. Studying personal space includes the ability to recognize the various zones of involvement and the activities, relationships, and emotions associated with each zone. This paper tries to formulate and define personal space in high density crowd situations in Kumbh Mela, one of the world’s largest mass religious gatherings. Video data of pilgrims taking part in the Panchkroshi Yatra, a religious walkathon which is a part of KumbhMela, is used for the analysis of factors affecting personal space. To identify the thresholds of personal space, walking speed of individuals, gender, presence of luggage and the number of males and females surrounding an individual have been considered. It is found that the average speed of the individual, the group size,and the gender ratio of group members have a significant effect on the personal space of an individual. Also, it is observed that the personal space follows an asymmetrical pattern rather than a symmetrical pattern.

Numa ótica que vai além da intentio específica da obra, a reflexão sugere se adoperar das Considerações Intempestivas de Nietzsche como chave hermenêutica para compreender uma faceta da sátira que se dirige à burguesia paulistana da época. O cotejamento de dois textos tão distantes ressalta o caráter medíocre da protagonista alemã, criando um paradoxo com a atitude reverencial que as demais personagens lhe tributam. Sob esse enfoque, o idílio se aproxima dos temas mais explorados pelo autor através da apresentação de um imaginário partilhado pela burguesia, onde domina a devoção acrítica às formas culturais estrangeiras em detrimento das brasileiras. Ressalta, assim, a imagem tragicômica de uma classe dirigente ridícula, mas consciente de seu poder.
Palavras-chave: Mário de Andrade; Amar, verbo intransitivo; Nietzsche; modernismo; burguesia.
Vidas secas e o ensaio de interpretação social
Authors: Alves Ricardo Luis Pedrosa
Published: March 2020

Resumo: O artigo analisa de modo comparativo o romance Vidas secas, de Graciliano Ramos, e o ensaio de interpretação social Os sertões, de Euclides da Cunha. Através da comparação das estratégias compositivas e narrativas presentes nos dois livros, como o “narrador sincero” de Os sertões e o uso do indireto livre em Vidas secas, o artigo mostra aproximações e diferenças entre os dois clássicos brasileiros. Também são comparadas as perspectivas intelectuais que orientam o romance e o ensaio, no cientificismo de Euclides da Cunha e na perspectiva sociologicamente crítica adotada por Graciliano Ramos. O artigo ressalta as diferenças também na perspectiva social dos autores, através da análise da representação da violência institucional do Estado nas duas obras. As análises foram realizadas com o apoio de discussões presentes em Willi Bolle, Luís Bueno, Antonio Candido, Miriam Gárate e Luiz Costa Lima, entre outros.
Palavras-chave: Vidas secas; Os sertões; ensaio de interpretação social; narrador sincero; indireto livre.
Por uma constituição de uma fortuna crítica da Revista Moderna (1897-1899)
Authors: Flexa Andreza dos Santos
Published: March 2020

Resumo: O objetivo do presente artigo consiste na constituição de uma fortuna crítica da Revista Moderna, propriedade de Martinho Arruda Botelho, publicada em Paris para circulação no Brasil, entre os anos de 1897 e 1899. Trata-se de uma revista literária e de variedades, um magazine ilustrado produzido em papel couché, com aproximadamente 36 páginas, que possibilitou a circulação e difusão de textos de diversos autores, antes mesmo de terem sido impressos em livros, como no caso do conto “José Matias”, de Eça de Queirós. Para tanto, foram realizadas pesquisas nas fontes primárias que circularam no mesmo período em que a Moderna, além da busca por monografias, dissertações, teses, artigos e outros materiais que fizeram uso da referida revista como objeto de estudo ou fonte de dado. Com essas informações, foi construído um banco de dados valioso, o qual permitirá aos interessados em pesquisas com fontes primárias uma visão geral do que foi e continua sendo dito sobre a Revista Moderna.

Drummond e o acontecimento ontológico
Authors: Andrade Abah
Published: March 2020

Resumo: O presente ensaio de filosofia pretende analisar o poema “Ser”, de Carlos Drummond de Andrade, à luz de algumas reflexões de ordem ontológica. Não partiremos da análise literária, mas tentaremos chegar a ela pelo impulso da própria reflexão filosófica, que se inicia na primeira parte com uma indagação muito próxima do estilo do segundo Heidegger, porém sem a preocupação de manter-se na ortodoxia heideggeriana; e que só se completa com a meditação sobre Drummond, cujo poema oferece não só oportunidade para pensar a questão do ser no limiar de certa concepção de temporalidade, como também se dá ele mesmo como uma forma possível desse pensamento do limite entre ser e tempo. Para tanto, mais que uma simples referência à noção freudiana de pulsão de morte parece surgir como uma exigência de primeira necessidade.
Palavras-chave: acontecimento ontológico; forma esquizofrênica; poesia; Drummond.

ENVIRONMENTAL PERMIT PROCESS ON EMISSIONS OF ASPHALT PLANT
Authors: BİNGÜL Züleyha , ALTIKAT Aysun
Published: March 2020

Asphalt plants are the facilities where in the
coating material on the roads, which vehicle traffic flows on it and is defined
as the main usage area in Turkey as well as all over the world and known as
asphalt by most people, was produced. Asphalt plants bring significant
environmental problems if necessary precautions are not taken during asphalt
production. The most important of these problems are the emissions of dust and
gas which are given to the atmosphere and cause air pollution. In Turkey, a
number of legal arrangements have been made in order to prevent, reduce and
control the negative effects of activities and facilities which have a
polluting effect on the environment. The
Environmental Permit and License Regulation is also one of these legal arrangements.
Article 11 of the Environmental Law No. 2872 contains the following provision:
“Facilities and enterprises, that are not considered appropriate to discharge
their wastes generated during production, consumption and service activities in
directly or indirectly to the receiving environment, and settlement units are
obliged to treat and dispose of their wastes in accordance with the standards
and methods determined in the regulations and to obtain the permits
envisaged". In this respect, the Environmental Permit and License
Regulation, which was prepared based on the Environment Law, was published in
the Official Gazette No. 29115 dated September 10, 2014 and entered into force
on November 1, 2014. In this
paper, it is examined the emissions permit process of the sector to be in
control and remain at a minimum level of the atmospheric pollutant impact
during operation of asphalt plant which has a production capacity of 30 tons per
hour and works 8 hours per day,  in
Turkey. There are two types of emission sources: point and
area. The results of dust and gas measurements in emission sources are
evaluated within the scope of Control of Industrial Air Pollution Regulation.
Since the pollutant emissions do not exceed the limit values specified in the
regulation, the emission issue environmental permit can be given to the
facility.
USE OF TURKISH BENTONITE MINERAL AS AN ADDITIVE FOR POLY(LACTIC ACID) BASED BIO-COMPOSITE MATERIALS
Authors: Dike Ali Sinan
Published: March 2020

In this study, Turkish bentonite (BN) mineral is subjected to silane treatment in order to enhance its compatibility for poly(lactic acid) (PLA). Neat and surface silanized BN powders are compounded with PLA using melt blending process at the concentrations of 5, 10, 15 and 20 wt%. Surface characteristics of BN samples are examined by infrared spectroscopy. Mechanical, thermo-mechanical, water resistance, melt flow and morphological investigations of composites are performed by tensile and impact tests, dynamic mechanical analysis (DMA), water absorption test, melt flow rate test (MFR) and scanning electron microscopy (SEM) analysis, respectively. Mechanical test results show that BN additions lead to increase in tensile strength and modulus of PLA. The maximum improvement is obtained for 15 wt% of silanized BN containing composite. Silanized BN filled PLA displays higher impact performance compared to untreated BN sample. Impact energy values of composites increase with increase in loading ratio. Silanized BN containing composite with 20 wt% concentration gives the highest storage modulus according to the DMA study. Glass transition temperature of PLA is improved by the inclusions of all BN samples. Additions of BN make slight decreases on MFR value of PLA. However, these reductions are found to be negligible in terms of its effect on processing of material. Water uptakes of composites are found to be higher than that of PLA. Composites containing silanized BN have lower water absorption values than neat BN samples due to the hydrophobicity of silicon containing surface. SEM characterization reveals that more homogeneous dispersion in PLA matrix is observed for silane treated BN compared to neat BN particles thanks to improvement of interfacial adhesion between BN and PLA matrix.
Configuração espacial, Copa do Mundo 2014 e valorização imobiliária no bairro de Lagoa Nova (Natal / Brasil)
Authors: Do Nascimento Rodrigo Costa , Dantas George Alexandre Ferreira , Trigueiro Edja Bezerra Faria
Published: March 2020

Grandes obras urbanas de megaeventos são referidos pela literatura como a expressão do processo de acumulação capitalista e da destruição criativa de setores das cidades. As mais-valias geradas pelas transformações espaciais dessas obras são capazes de adicionar valores imobiliários ao ambiente construído. O espaço, portanto, revela-se como variável dependente e independente de interesses econômicos, possuindo ou assumindo, em suas propriedades configuracionais, potenciais de lucros. Dentre essas propriedades, destaca-se a acessibilidade espacial que consiste na facilitação do movimento gerado essencialmente pela configuração espacial com seu conjunto de barreiras e permeabilidades. Em algumas situações as obras são implantadas em áreas de acessibilidade elevada, se apresentando como coadjuvantes do processo de valorização. Em outras, são capazes de assumir um protagonismo compartilhado com o espaço nesse processo, uma vez que são associadas à novas conexões. No bairro de Lagoa Nova, em Natal/Brasil, a implantação da Arena das Dunas, por ocasião da Copa do Mundo de 2014, ao mesmo tempo que alterou a paisagem local, articulou-se a uma tendência de gradual valorização imobiliária nos últimos 20 anos, coincidente com a transformação da localidade em um novo centro ativo. Diante disto, busca-se perceber, através da Análise Sintática do Espaço, relações entre acessibilidade topológica gerada pela própria configuração espacial, obras urbanas de grande impacto e a valorização imobiliária em Lagoa Nova, aplicando medidas quantitativas de integração – potencial de centralidade - e choice (escolha) –potencial de atravessamento - a partir de representações lineares de segmentos (linhas fracionadas nas interseções com outras linhas que cobrem o traçado urbano). Objetiva-se detectar ainda se valores mais elevados de imóveis estão melhor relacionados à consolidação de um núcleo de elevada integração e atravessamento, o que se apresentaria como vantagem locacional dentro de uma lógica de implantação estratégica da arena. Foram coletados valores de apartamentos residenciais em escrituras de compra e venda cartoriais - correspondentes a um intervalo de cinco anos (2012 a 2016) – categorizados segundo número de dormitórios (de 1 a 4). Realizou-se a análise à luz do cruzamento entre a localização desses valores e medidas de integração e choice em uma base mapeável georreferenciada.
