DETERMINATION OF MATERIAL LOADING COEFFICIENT IN THE GRINDING CHAMBER OF A BALL DRUM MILL
Authors: Hanzarov A. , Hanin S. , Voronov V. , Mordovskaya O. , Chalov V.
Published: September 2023

The predominant application of ball drum mills in industrial enterprises for the comminution process of various materials, which is one of the most energy-intensive basic technological processes, is demonstrated in this scientific article. As one of the parameters that can enhance the efficiency of the comminution process, the rational quantitative ratio of grinding bodies to the material being ground is noted. To calculate the material loading coefficient in the grinding chamber, the feasibility of developing a mathematical description is shown. This allows to determine the change in the area of gaps between grinding bodies in a cross-sectional plane perpendicular to the longitudinal axis of the mill's body, as the rotational frequency changes. A mathematical description is obtained to determine the area of the ball-material load in the cross-sectional plane of the grinding chamber during the static state of the mill's body and at different rotational frequencies. Using this mathematical description, research on the change in the area occupied by the ball-material load in the transverse section of the grinding chamber during the transition of the mill's body from the static state to the operating state is conducted. Regularities of its changes for an industrial-sized mill are determined. At different values of the filling coefficient of grinding bodies, it is established that the transition of the mill's body from static to operating state leads to an increase in the area of the transverse section of the ball-material load by an amount close to 17 %. An expression is proposed to determine the material loading coefficient in the grinding chamber corresponding to its operating rotational frequency.
DETERMINATION OF THE ELASTIC MODULUS OF CONCRETE IN REINFORCED CONCRETE BEAMS BY THE RATE OF VIBRATION DAMPING
Authors: Abashin E.
Published: September 2023

The article shows a method for determining the modulus of elasticity of concrete by the measured dynamic characteristics of the tested structure – the damping coefficient of vibrations of reinforced concrete unstressed beams operating in the first stage of the stress-strain state.

We have proposed to use this characteristic of reducing the amplitude of vibrations, which takes into account the loss of kinetic energy in a reinforced concrete beam. It is assumed that a change in the modulus of elasticity of concrete in the considered range will significantly affect the rate of damping of vibrations, since with an increase in the modulus of elasticity of concrete, the elastic properties of the reinforced concrete element prevail over the plastic properties. When conducting experiments, one should strive for the same support conditions and introduce an equal level of energy into the oscillatory system. In this case, the energy loss in the reinforced concrete beam, expressed by the value of the vibration damping coefficient, will allow to determine the modulus of elasticity of concrete with a higher degree of probability in comparison with the practiced mechanical or ultrasonic methods.

We have developed a new method for determining the elastic modulus of concrete, based on the empirical determination of the vibration-damping coefficient of reference structures of a given type and size and the construction of a graphical dependence of the vibration damping coefficient on the elastic modulus of concrete. We have obtained greater accuracy in determining the modulus of elasticity of concrete in comparison with the practiced mechanical or ultrasonic methods.
FEATURES OF FORMING AND DEVELOPMENT OF THE ARCHITECTURAL ENVIRONMENT OF SMALL HISTORICAL CITIES IN THE BELGOROD REGION (ON THE EXAMPLE OF THE CITY OF VALUYKI)
Authors: Arslan M. , Ladik E.
Published: September 2023

The article is dedicated to analyzing the peculiarities of the formation and current state of the architectural environment of small historical cities in Russia. The research is conducted using the example of the historical small city of Valuyki, located in the southern part of the Belgorod region. The stages of formation of the planning structure and the characteristics of the historical development of the central part of the city are identified, and a landscape-visual analysis of the territory of the city center is conducted. As a result of the research, problems of development and visual perception of the urban environment are identified, including: discordant color solutions of modern buildings, inconsistency between the architectural appearance of new buildings and the image of the surrounding historical architecture, insufficient pedestrian connectivity in the central part of the city, and degradation in certain areas within the urban environment. To preserve the identity of the architectural environment of the small city of Valuyki, directions for its prospective development are proposed. They are the development of the riverside territory of the Valuy River, the development of a design code for the urban environment, the implementation of a navigation system for the central part of the city, and the organization of pedestrian tourist routes. The proposed measures are aimed at preserving the uniqueness of the architectural environment of the small city, which is an important element in preserving the historical and cultural heritage of the region.
THE PRINCIPLE OF IMPROVING THE VISUAL IMAGE OF ARCHITECTURAL OBJECTS IN SMALL TOWNS IN CENTRAL RUSSIA
Authors: Gribkov A.
Published: September 2023

Visual environment - the space of the visible surrounding urban (architectural) environment. The visual image is formed by everything that surrounds the person, ranging from buildings and structures to architectural elements of the facade. The image may have a different psycho-emotional influence on the person, negative or positive. At the moment of being in the space of the architectural environment, the presence of aggressive and homogeneous fields are causes of deterioration of the emotional state, person's mood. Aggressive and homogeneous fields are one of the types of visual pollution of the architectural environment. Aggressive fields are characterized by the presence of repetitive identical objects in the field of view of the human eye (for example, a series of equally arranged windows on the facade of a building). Homogeneous fields are one of the types of negative visible environment, characterized by the predominance of homogeneous surfaces of glass, concrete or metal (for instance, homogeneous facades without windows of residential or public buildings). The article presents a material on the development of the principle of improving the visual appearance of architectural objects of small towns in Central Russia. By the concept of "Architectural objects" is meant - buildings, structures, architectural elements of the facades of various objects, small architectural forms.

The result of the material is the development of a hypothetical model to improve the visual image of architectural objects. The model reflects the system of the above principle and the apparatus controlling the activities in the field of video ecology, consisting of state and municipal authorities.
Identité et transmission [Bilinguisme(s) et identité familiale : le non-dit]
Authors: Haase Danielle
Published: September 2023

Il s'agit dans ce récit autobiographique d'une situation familiale qui favorise le bilinguisme et l’adaptation sociale (la famille est française, le père, la mère et les deux enfants ont émigré aux Etats-Unis). Très peu de tension entre l'univers familial et l'environnement, la transmission se faisant en fonction d'une revalorisation extrême des capacités d'adaptation de "la famille" depuis des générations. Ce n'est que peu à peu que la véritable problématique (sociale et langagière) de cette capacité miraculeuse peut commencer à être pensée différemment et que le sentiment d'identité s'enracine dans le non-dit familial, dans le jeu des identifications et de la sexuation. Pour la fille, il s'agit de savoir comment, dans quelles répétitions et dans quels déplacements, être la fille du père. Voilà l'interrogation qui se cache et se dévoile dans le jeu des bilinguismes...
Interval state estimator for linear systems with known structure
Authors: Gubarev Vyacheslav , Mishchenko Mykhailo
Published: September 2023

It is often required to control a system whose state is not observable directly. Instead, there are indirect incomplete and noised measurements of its state. In such situation it is required to estimate current system’s state from these indirect measurements first in order to control the system. For this purpose the Kalman filter is the long established and classical approach on estimation of linear systems state from indirect measurements. It is recursive by desin, and thus indirectly takes into account the whole previous history of measurements. Here we explore an alternative approach: estimation with measurements on a limited historic horizon. The article first discusses application of the generalized linear least squares (GLLS) estimator to this problem and conditions under which it is appropriate to use this method. For situations when it is not fully appropriate, we propose a way to represent the GLLS estimator as a quadratic cone programming problem which helps producing its modifications tuned for various nonstandard linear system designs. The article also explores various properties and behavior of the GLLS estimator and its modifications. For instance, it is completely expectable that such estimators demonstrate diferent precision with different number of historic measurements considered. Thus, application of the absolute condition number of the GLLS estimator to choosing an optimal horizon length was explored. It was demonstrated how the absolute condition number of GLLS, while being a hard limit on estimation precision, also limits expected value of error norm. Choice of the best horizon length was discussed from both of these points of view. For situations when best possible estimation precision is still not enough, a regularization method was proposed. Pros and cons of this regularization method and a way to make an informed choice regarding the degree of regularization was explored. The theoretical results were confirmed with computational experiments.

Published: September 2023

In this study; it is aimed to analyze the temporal and spatial changes in land use/land cover of Trabzon province with the population increase in the 28-year period between 1990-2018 by analyzing it with CORINE maps and landscape metrics. Within the scope of the study, temporal variation analysis was carried out using CORINE maps of the years 1990, 2000, 2006, 2012 and 2018. In Trabzon, according to the CORINE classification system, a total of 4 main groups have been identified at the first level, and at the third level, 19 land use/land cover classes have been identified for 1990, 20 for 2000, 24 for 2006, and 26 for 2012 and 2018. It was observed that the most differentiation occurred in the agricultural areas class in the 28-year period. In addition, the metrics of class area (CA), number of patches (NumP), mean patch size (MPS), edge density (ED), total edge (TE) and mean shape index (MSI) were calculated through ARCGIS's Patch Analyst plugin in the study. The changes that have occurred have been examined. Accordingly, there has been a decrease in the size of forest and seminatural areas and agricultural areas with the increase in the size of the artificial surfaces due to the increase in human activities and population over the past 28 years. In addition, due to the continuous increase in the number of patches in the agricultural areas over time and the decrease in the average size of the patches, the fragmentation of the agricultural areas has been more common. The least change was in the water bodies. In line with the findings obtained, sustainable planning and land use suggestions for land use were presented.

Resident perspectives on police involvement in the response to mental health crises
Authors: Addison Helena , Shefner Ruth , Wood Jennifer , Anderson Evan
Published: September 2023

Exclusive reliance on police in the response to mental health crises can result in avoidable injury or missed connections to supportive services. Many cities are experimenting with co-deploying police officers alongside health professionals or deploying teams comprised entirely of civilian health professionals. No studies have explored the perspectives and preferences about these programs among residents in structurally disadvantaged areas where: mental health distress is more common, mental health services are less accessible, and involvement with police is more frequent and fraught. In this survey of residents from two such areas, many respondents suggested that police presence is necessary during the response to mental health crises because of the risk of violence but were simultaneously uncomfortable with police officer involvement. Discomfort with police involvement was especially strong among younger and Black residents. Support for co-deployment was high across all subgroups.
Wales without violence: A framework for preventing violence among children and young people
Authors: Barton Emma R. , Snowdon Lara C. , Parry Bryony , Walker Alex
Published: September 2023

Violence among children and young people (CYP) is a complex societal issue that has detrimental impacts on the health and well-being of children, young people, and adults throughout their lives. Population health research tells us that CYP are adversely at risk of experiencing violence and are at higher risk of experiencing multiple forms of violence. However, evidence suggests that prevention approaches are most effective when implemented with CYP and can have positive health, well-being, and social impacts across the life-course.
This social innovation narrative sets out how the Wales Violence Prevention Unit and Peer Action Collective Cymru coproduced a strategic multi-agency framework for the prevention of violence among CYP in Wales. The first of its kind to be developed in the United Kingdom, this national framework acts as a guide to strategic action on violence prevention, amplifying the voices of CYP, and providing evidence of “what works.”
This evidence-informed, coproduced framework used an innovative participatory design process to listen to the voices of a diverse range of stakeholders, highlighting the voices of CYP. Informed by the views and experiences of over 1,000 people in Wales, and grounded in the lived experiences of CYP, the Framework proposes nine strategies to prevent violence among CYP as part of a public health approach to violence prevention. These strategies represent evidence-based approaches proven to reduce violence among CYP, address the risk factors for youth violence, and build individual, community and societal resilience.
Preventing sexual harassment through a prosocial bystander campaign: It’s #SafeToSay
Authors: Walker Alex , Barton Emma R. , Parry Bryony , Snowdon Lara C.
Published: September 2023

Sexual harassment is pervasive and often hidden, occurring on a continuum of violence against women, domestic abuse, and sexual violence (VAWDASV), and often underpinned by problematic attitudes and beliefs. Bystander interventions have been shown to illicit positive outcomes in VAWDASV prevention. Therefore, the Wales Violence Prevention Unit created the #SafeToSay campaign, to encourage prosocial bystander responses against sexual harassment. The campaign was delivered in two phases. Phase One was delivered in Cardiff and Swansea, calling everyone to action. Phase Two was delivered in Swansea and specifically engaged men. Both phases received a process and outcomes evaluation using social media and website analytics, and a public perception survey. The surveys showed that members of the public felt that #SafeToSay had drawn people’s attention to an important issue and had provided them with some of the information and skills needed to take prosocial bystander action against sexual harassment. However, men had particularly negative responses to some of the social media advertisements in Phase Two. Possible explanations for this have been explored. When considering future iterations of #SafeToSay, more work is needed to understand what works in engaging men and boys in violence prevention campaigns through research, focused engagement, consultation and coproduction with this group. Similarly, refining the target audience, including exploring options for targeting other socio-demographics, should be considered. This could be achieved through behavioural insights work, such as surveys, interviews, and focus groups. This would support the development of messaging to make the campaign more relatable to the desired target audience.
Reducing criminal recidivism in Alaska: The Set Free Model
Authors: Ray Ryan , Madison Alli
Published: September 2023

Crime associated with problematic substance use remains a defining characteristic in the United States criminal justice system. In Alaska, a perennial leader in US criminal recidivism rates, thousands of formerly incarcerated individuals continue to commit crimes and misuse drugs and alcohol following their release from incarceration. The total cost of these crimes to victims and Alaska’s criminal justice system is over $2.3 billion annually.
The Set Free Model is a comprehensive intervention addressing the primary risk factors of criminal recidivism within an innovative therapeutic campus environment. Occurring within a four-phase operational framework for an average of 6 to 18 months, participants engage in a suite of services proven to reduce further criminal recidivism. These services include certified peer support, supportive housing, co-occurring substance use disorder treatment, career placement, intensive case management, and positive community reintegration.
Over an 18-month period, the nonprofit treatment agency Set Free Alaska provided the Set Free Model to a sample of 32 formerly incarcerated adults at high risk of criminal recidivism. Participants displayed a 21.8% recidivism rate compared with the current rate of 66.4%. Treatment engagement rates significantly improved compared with traditional outpatient rates (94.7% vs. 66.7%). Employment rates were also remarkable compared with national employment rates at 1-year postrelease (100% vs. 37%). Validated calculations indicate the sample population may achieve $6.25 million in cost savings and net economic benefits. Evaluation results indicate the model possesses significant potential to reduce criminal recidivism and should be further expanded and evaluated.
Psychonautical engineering: Synergizing the magic of mindfulness, mushrooms, and mindsets for police officer well-being
Authors: Stevenson Renae M.
Published: September 2023

The setting of policing exposes its officers to a host of negative health outcomes physiologically, psychologically, and spiritually. Policing mindsets around accessing mental health are far from fixing the epidemic of its mental health crisis or being able to sustain a healthy workforce. Policing is losing the battle with a misguided and a scientifically misinformed war on drugs. Canadian legislators are shifting mindsets from decriminalizing substance use towards applying a public health lens to the mycelium underlying its root causes. So too should its peace officers—not just to restore peace in society—but also in their own minds and in their dysregulated nervous systems by synergizing psilocybin’s neural benefits with mindfulness-based psychotherapy. Western science’s exploration into the healing magic of mushrooms and mindfulness is in its infancy compared with the centuries of wisdom from both Indigenous science and eastern contemplative traditions. Not only does their fusion amplify hope for those suffering but perhaps it offers a scientific key to the neurogenesis of resilience. This is a pracademic trip driven by a retired and now reformed agent from Canada’s War on Drugs.

COVID-19 pandemisi yaşamı her boyutuyla etkilemiştir. Bu çalışmada, fen bilgisi öğretmen adaylarının COVID-19 sonrası sosyal medyaya yönelik tutumları incelenmiştir. Genel tarama modelindeki araştırmanın katılımcılarını Ankara’daki iki kamu üniversitesindeki 401 öğretmen adayı oluşturmuştur. Katılımcılara ait cinsiyet, sınıf düzeyi, üniversite, sosyal ağ üyeliği sayısı, internet kullanım amacı ve sosyal medya kullanım süresi bilgilerinin alınmasında araştırmacıların geliştirdiği kişisel bilgi formu kullanılmıştır. Dört alt boyutu olan Sosyal Medya Tutum Ölçeği (SMTÖ) kullanılan bir diğer araçtır. Yüz yüze toplanan veriler çeşitli betimsel yöntemler, faktör analizi, 10 bağımsız gruplar t-testi, 20 tek-yönlü ANOVA ve 11 Tukey testi kullanılarak analiz edilmiştir. Buna göre, sosyal medya tutumlarının alt boyutlara göre değişmekle birlikte, hafif pozitif olduğu görülmüştür. Cinsiyet, sosyal ağ üyeliği sayısı, internet kullanım amacı ve sosyal medya kullanım süresi değişkenleri açısından istatistiksel olarak anlamlı farklılıklar bulunmuştur. Bu durumun SMTÖ’nün özellikle “paylaşım ihtiyacı” ve “sosyal yetkinlik” alt boyutlarındaki farklılıklardan kaynaklandığı anlaşılmıştır. Son olarak bulgular kapsamında çeşitli önerilerde bulunulmuştur.

Introducción: El neumotórax oculto (NTXO) se encuentra hasta en el 15% de los traumatismos torácicos. Existen antecedentes del manejo conservador de esta patología (sólo observación), aunque su práctica continúa siendo discutida especialmente en traumatismos penetrantes. El objetivo de este trabajo es describir nuestra experiencia en el manejo conservador del NTXO.Métodos: Estudio de cohorte retrospectivo realizado durante un período de 3 años en un Hospital de Trauma nivel I. Se incluyeron pacientes con traumatismo torácico (cerrado o penetrante) con NTXO. Se dividieron en dos grupos (conservados o drenados) realizándose una comparación de su evolución.Resultados: En 3 años fueron admitidos con traumatismo torácico 679 pacientes. De 93 pacientes con NTXO, 74 (80%) fueron conservados inicialmente y 19 (20%) tratados con drenaje pleural. Dos (3%) presentaron progresión del neumotórax en el seguimiento radiológico (conservación fallida). No se registraron complicaciones relacionadas con la ausencia de drenaje pleural. Las complicaciones y estancia hospitalaria fueron menores en el grupo de manejo conservador.Conclusión: Pacientes con NTXO por traumatismo de tórax (cerrado o penetrante), sin requerimiento de ventilación asistida y hemodinámicamente estables, pueden manejarse de manera conservadora con un monitoreo cercano durante 24 horas en forma segura, con menor tasa de complicaciones y de estancia hospitalaria.

ASSENTAMENTOS DE REFORMA AGRÁRIA NO CEARÁ: ESPAÇOS DE RESISTÊNCIA DO CAMPESINATO
Authors: Diniz Aldiva Sales
Published: September 2023

O objetivo deste artigo é analisar os Assentamentos de Reforma Agrária, frutos da luta pela terra e como estes se constituem como território da resistência dos camponeses. A luta pela terra não é somente uma forma de expor a situação de exclusão do camponês, mas um modo de resistência aos processos de expropriação e exclusão do acesso à terra. É evidente que não basta somente a conquista da terra, mas os camponeses podem usá-la como base de uma luta que venha desarticular a acumulação capitalista, refletida na própria concentração fundiária.  A conquista da terra, na instalação do assentamento, significa a continuidade da luta pois, com a sua conquista as lutas não terminam, desdobram-se em outras. Podemos afirmar que os assentamentos são espaços da resistência, onde se organiza o território da expansão da agricultura camponesa, baseada no trabalho da família. Neles, estão sendo semeadas a utopia camponesa, o acesso à terra, a liberdade de trabalhar, bem como, a necessidade da reprodução da família, que se resume na conquista da terra. Isso é uma particularidade do camponês enquanto identidade: para ele não se pensa a terra sem se pensar a família e o trabalho. O trabalho, a família e a terra são valores que remetem a uma moral e, ao mesmo tempo, são categorias indissociáveis.

La Corporación Universitaria Adventista (UNAC), en su proceso de consolidación como institución de educación superior, busca que los documentos institucionales que intentan describir su perspectiva filosófica sobre la educación estén en constante desarrollo. En este contexto, se planteó la construcción de un documento que sintetice las concepciones fundamentales que subyacen al quehacer de la educación en la UNAC y su articulación con las exigencias de la sociedad actual. Este engranaje, que sólo se puede dar a partir de una lectura profunda del contexto en que está insertada la Institución, implica nuevos retos y responsabilidades por parte de los miembros de la comunidad educativa, un discurso actualizado y una perspectiva abierta y dinámica de sus procesos y condiciones educativas del mundo de hoy. En este marco, se presenta la Propuesta Pedagógica de la Corporación Universitaria Adventista. El presente documento es el resultado de una investigación que convocó a docentes de diferentes secciones, con el ánimo de promover la investigación interdis- ciplinar en la Institución y consolidar la comunidad académica en torno al quehacer de la educación y la formación, a partir de su propia filosofía educativa y de los tres pilares de la educación superior en Colombia: docencia, investigación y proyección social.

Impressões da “decadência”
Authors: Santos Zidelmar Alves
Published: September 2023

Neste trabalho lançamos um olhar para os relatos dos viajantes estrangeiros que estiveram em Ilhéus no século XIX: Maximiliano de Wied-Neuwied, Spix, Martius e Maximiliano de Habsburgo. Consideramos seus apontamentos sobre a urbanização da vila em questão. Compreendemos que tais relatos influenciaram a historiografia consagrada na construção de um quadro de decadência, estagnação e isolamento que só seria rompido com a explosão da lavoura cacaueira no sul da Bahia. Concluímos que as impressões dos viajantes estrangeiros acerca da decadência da Ilhéus Oitocentista foram demasiado exageradas, considerando que seus olhares sobre a região demonstraram o forte preconceito que o europeu tinha com territórios que não apresentavam o mesmo nível de desenvolvimento urbano que os países da Europa.

Published: September 2023

This paper presents a novel feature-line points tracking algorithm designed to be highly efficient and accurate for real-time monocular line-based SfM applications in man-made environments. The proposed algorithm exploits feature-line points proprieties to detect and extract long line segments and ensure their temporal evolution in the subsequent frames while handling line segment detection and tracking issues such as noisy images, over-segmentation, edge thresholding, false detections, occlusions, and ambiguous matches. To fulfill the real-time and embeddability constraints of our proposed method, we adopt the hardware/software co-design to achieve a suitable implementation with a scalable FPGA-based embedded heterogeneous architecture. Based on this, experimental results show the portability of the line segment detector block of this proposed algorithm on scalable FPGA-based embedded heterogeneous architectures, improving the acceleration of the sequential execution by about 98\%, whereas a 53\% improvement with GPU-based heterogeneous architectures. For qualitative and quantitative assessment, we exhibit extensive benchmarking with other state-of-the-art algorithms regarding feature-line segment extraction and tracking, showing the efficiency of the proposed algorithm and ensuring very hopeful real-time performance using two common datasets.  
Resource dimensioning of broadband satellite return networks affected by spatially-correlated rain fade
Authors: Lacoste Clement , Martins Wallace , Chatzinotas Symeon , emiliani luis
Published: September 2023

The use of Ka-band in satellite links has made rain attenuation a major concern in satellite network design. Fade mitigation techniques come at the expense of higher satellite resource consumption, such as bandwidth and power. An accurate estimation of this consumption is essential for the satellite service providers’ business case, product strategy, and overall service pricing. However, the spatial correlation of rain fade introduces a high level of model complexity, such that no method is available to compute its impact on resource consumption. This paper proposes a satellite resource dimensioning process that accounts for such a correlation. We formulate a quantile estimation problem based on the broadband service level agreements. Then, we solve this problem for a given confidence relative interval using spatially correlated rain fade sample generators. Finally, we provide numerical results for residential and enterprise broadband satellite scenarios. Results show that the satellite resource consumption predicted by our method is increased by up to 70% and reduced by up to 60% w.r.t. optimistic (independent) and pessimistic (fully correlated) rain fade assumptions, respectively.
