Published: September 2023

The arterial switch operation (ASO) has become the standard surgical treatment for patients with d-transposition of the great arteries (d-TGA). While ASO has significantly improved survival rates, a subset of patients develops a unique anatomical anomaly known as the gothic aortic arch (GAA). Understanding cardiac mechanics in this population is crucial as altered mechanics can have profound consequences on cardiac function and exercise capacity. The GAA has been associated with changes in ventricular function, hemodynamic, and exercise capacity. Studies have shown a correlation between the GAA and decreased ascending aorta distensibility, loss of systolic wave amplitude across the aortic arch, and adverse cardiovascular outcomes. Various imaging techniques, including echocardiography, cardiac magnetic resonance imaging (CMR), and cardiac computed tomography (CCT), play a crucial role in assessing cardiac mechanics and evaluating the GAA anomaly.  Despite significant advancements, gaps in knowledge regarding the prognostic implications and underlying mechanisms of the GAA anomaly remain. This review aims to explore the implications of the GAA anomaly on cardiac mechanics and its impact on clinical outcomes in young patients after ASO. Advancements in imaging techniques, such as computational modeling, offer promising avenues to enhance our understanding of cardiac mechanics and improve clinical management.

Pontrjagin duality on multiplicative gerbes
Authors: Blanco Jaider , Uribe Bernardo , Waldorf Konrad
Published: September 2023

We use Segal–Mitchison’s cohomology of topological groups to define a convenient model for topological gerbes. We introduce multiplicative gerbes over topological groups in this setup and define their representations. For a specific choice of representation, we construct its category of endomorphisms, and we show that it induces a new multiplicative gerbe over another topological group. This new induced group is fiberwise Pontrjagin dual of the original one, and therefore we called the pair of multiplicative gerbes “Pontrjagin dual”. We show that Pontrjagin dual multiplicative gerbes have equivalent categories of representations. In addition, we show that their monoidal centers are equivalent. Examples of Pontrjagin dual multiplicative gerbes over finite and discrete, as well as compact and non-compact, Lie groups are provided.
Hacia la democratización del sistema mediático europeo: análisis comparado de proyectos de reforma mediática en los programas de la izquierda alternativa.
Authors: Alvarez-Peralta Miguel , Rojas-And´res José Raúl
Published: September 2023

Introducción: Este artículo realiza una revisión comparativa y análisis crítico sobre las propuestas de reforma mediática de siete fuerzas europeas de la izquierda “alternativa” o “crítica”1, provenientes de seis países (España, Portugal, Grecia, Alemania, Reino Unido y Francia). Metodología: El objetivo es evaluar la existencia o posibilidad de hojas de ruta y horizontes comunes sobre esa cuestión para la izquierda crítica europea. Para ello, se acomete una revisión documental y análisis temático y volumétrico sobre los programas electorales de ámbito nacional más recientes de cada partido, se han recopilado y clasificado sus propuestas específicas y estilos de formulación, y se ha realizado sobre ello el análisis comparado. Resultados: Se proponen hasta tres taxonomías diferentes y compatibles para las medidas registradas. Las propuestas realizadas por diferentes partidos difieren notablemente tanto en volumen como en enfoque. Se ofrece una categorización de estas propuestas por ejes programáticos, temas y subtemas, así como un listado sintético de las de cada partido. Se identifican incompatibilidades, áreas comunes, y vacíos programáticos. Discusión: se discute la oportunidad de algunas formulaciones programáticas, y se localizan posibles incorporaciones de interés para el caso de las fuerzas políticas de origen español. Conclusiones: Queda descartada la primera hipótesis de investigación pero se valida el resto: sí existe ya de facto un cierto marco programático ampliamente compartido, aunque registra importantes puntos ciegos, que frecuentemente recaen sobre áreas diferentes en cada caso analizado, por lo que se comprueba la potencialidad de préstamos y aprendizajes mutuos entre los diferentes partidos y el potencial avance que esto podría suponer en la articulación de un marco programático común que genere sinergias hacia una reforma mediática democrática en el ámbito europeo.

Дискретные симметрии уравнений динамики с полиномиальными интегралами высших степеней
Authors: Kozlov Valery Vasil'evich
Published: September 2023

Рассматриваются системы с торическим конфигурационным пространством и кинетической энергией в виде "плоской" римановой метрики на торе. Потенциальная энергия $V$ - гладкая функция на конфигурационном торе. Динамика таких систем описывается "натуральными" гамильтоновыми системами дифференциальных уравнений. Если заменить $V$ на $\varepsilon V$, где $\varepsilon$ - малый параметр, то исследование таких гамильтоновых систем при малых значениях $\varepsilon$ относится к "основной проблеме динамики" по Пуанкаре. Обсуждается известная гипотеза об однозначных полиномиальных по импульсам интегралах уравнений движения: если имеется полиномиальный по импульсам интеграл степени $m$, то обязательно найдется линейный или квадратичный по импульсам первый интеграл. Эта гипотеза полностью доказана для $m=3$ и $m=4$. Обсуждаются случаи "высших" степеней, когда $m=5$ и $m=6$. Следуя теории возмущений гамильтоновых систем, вводятся резонансные прямые на плоскости импульсов. Если система допускает полиномиальный интеграл, то число этих прямых конечно. Найдены симметрии множества резонансных прямых, что дает, в частности, необходимые условия интегрируемости. Получены некоторые новые критерии существования однозначных полиномиальных интегралов.

Fermions from classical probability and statistics defined by stochastic independence
Authors: Accardi Luigi , Lu Yun Gang
Published: September 2023

The case study of fermions and the attempt to deduce their structure from classical probability opens new ways for classical and quantum probability, in particular, for the notion of stochastic coupling which, on the basis of the example of fermions, we enlarge to the notion of algebraic coupling, and for the various notions of stochastic independence. These notions are shown to be strictly correlated with algebraic and stochastic couplings. This approach allows to expand considerably the notion of open system. The above statements will be illustrated with some examples. The last section shows how, from these new stochastic couplings, new statistics emerge alongside the known Maxwell-Boltzmann, Bose-Einstein and Fermi-Dirac statistics.

Геометрия группы Ли. Инвариантные метрики и динамические системы, двойственная алгебра и их приложения в групповом анализе одномерного кинетического уравнения
Authors: Borovskikh Aleksey Vladislavovich
Published: September 2023

На группе Ли вводится семейство метрик, инвариантных относительно этой группы и показывается, что кривые, инвариантные относительно этой группы, во всех введенных метриках являются спиралями (т. е. имеют все постоянные кривизны).
Оказывается, что существенную роль при этом играет алгебра, которая названа двойственной и задана на той же группе. Основным отношением между этими алгебрами является то, что траектории однопараметрических групп, порожденных одной алгеброй, являются инвариантными кривыми в метрике, инвариантной относительно другой алгебры. То, что эти кривые оказываются спиральными, отличается от подхода Картана, который рассматривал траектории однопараметрических групп как геодезические в некоторой метрике.
Представленные результаты связаны с анализом геометрического смысла полученной ранее классификации одномерных кинетических уравнений, где инвариантные кривые представляли собой траектории частиц.
Recurrent Neural Network Model for On-Board Estimation of the
Side-Slip Angle in a Four-Wheel Drive and Steering Vehicle
Authors: Giuliacci Tiziano Alberto , Ballesio Stefano , Fainello Marco , Mair Ulrich , King Julian
Published: September 2023

A valuable quantity for analyzing the lateral dynamics of road vehicles is the
side-slip angle, that is, the angle between the vehicle’s longitudinal axis and
its speed direction. A reliable real-time side-slip angle value enables several
features, such as stability controls, identification of understeer and oversteer
conditions, estimation of lateral forces during cornering, or tire grip and wear
estimation. Since the direct measurement of this variable can only be done with
complex and expensive devices, it is worth trying to estimate it through virtual
sensors based on mathematical models. This article illustrates a methodology for
real-time on-board estimation of the side-slip angle through a machine learning
model (SSE—side-slip estimator). It exploits a recurrent neural network trained
and tested via on-road experimental data acquisition. In particular, the machine
learning model only uses input signals from a standard road car sensor
configuration. The model adaptability to different road conditions and tire wear
levels has been verified through a sensitivity analysis and model testing on
real-world data proves the robustness and accuracy of the proposed solution
achieving a root mean square error (RMSE) of 0.18 deg and a maximum absolute
error of 1.52 deg on the test dataset. The proposed model can be considered as a
reliable and cheap potential solution for the real-time on-board side-slip angle
estimation in serial cars.
Using High-Resolution X-Ray Computed Tomography to Test the Preparation of Stalagmites for Paleo-Climate Reconstruction
Authors: Sekhon Natasha , Banner Jay , Breecker Dan , Tremaine Darrel
Published: September 2023

Stalagmites being prepared for paleoclimate analysis should typically be slabbed along the central growth axis. This is an important first step because it allows for the highest resolution of sampling with minimal over- or under-sampling of the growth layers. Further, stable isotope ratios and trace element concentrations along the central growth axis most closely record climate variability. Choosing how to slab to best expose the central growth axis for geochemical sampling is challenging based on external morphology alone. High-resolution X-ray computed tomography (XRCT) can provide the ability to discern the internal growth morphology of stalagmites non-destructively, inexpensively, and rapidly. These data can inform selection of optimal slabbing plane(s) and can help identify locations for preliminary U-series dating. We develop a conceptual screening model to assess rapidly the internal morphologies of uncut stalagmites. The specifics of screening the internal morphologies through XRCT scans include investigating the internal porosity of the sample, the number and size of voids and hiatuses, and the presence and absence of growth layers and growth axes. We demonstrate that XRCT scans capture the migration of center of growth in uncut stalagmites of both simple and complex internal morphologies. XRCT scanning facilitates the investigation of stalagmites with complex internal growth banding, opening up avenues to work on such samples when stalagmites with simpler internal morphologies are not available. Further, screening stalagmites for paleoclimate reconstructions using XRCT improves the sustainability of speleothem science by helping researchers select which stalagmites should be returned to caves without destructive slabbing, thereby minimizing impact on caves.

A serializing particle ń with discourse functions in Kusaal
Authors: Abubakari Hasiyatu
Published: September 2023

This paper presents novel empirical data revealing a previously unidentified particle n in Serial Verb Constructions in Kusaal. The issue that requires attention is to find out the status of the said particle in SVCs in the language. The central question is whether the observed particle is an overt marker of coordination or subordination which is likely suppressed in other instances of SVCs in the language. The particle n has several functions in Kusaal and other Mabia languages with more being discovered as research on these languages keeps developing. It functions as a subject focus marker in Kusaal, Gurenɛ, and Dagbani and a serializing connector in Moore. It will be observed that the particle n is not obligatory in SVCs in Kusaal and its presence encodes an emphatic/ focus interpretation on the verb it precedes. This study is qualitative with data gathered from both primary and secondary sources.
Ghana’s democracy and the digital public sphere: some pertinent issues
Authors: Gyekye-Jandoh Maame Adwoa , Hakim Ahmed Abdul
Published: September 2023

Ghana’s media has been one of the biggest bulwarks of its nascent democracy since the transition to democratic rule in 1992. What has become known as the Fourth Estate of the Realm is now gradually being digitally networked as a result of the emergence of new media technologies. Using existing data mostly from media think-tanks such as Penplusbytes, Media Foundation for West Africa (MFWA), media and other online sources, this paper appraises the role of digital media in the process of consolidating Ghana’s democracy under the Fourth Republican Constitution within the lens of Habermas’ concept of the public sphere. The study focuses on the 2016 and 2020 general elections of Ghana and analyses the influence of digital media in strengthening democratic values such as political participation, activism and public opinion formation. We conclude that the Habermasian model of the structural transformation of the public sphere (1962) is partly applicable to the Ghanaian media landscape. Although challenges such as the elite stranglehold on the traditional media landscape have been widespread since the beginning of the political transition in 1992, the emergence of the new media has brought new and complex dimensions to the debate. Specifically, while new media platforms have made immense contributions towards enhancing a general liberal environment, they suffer from several drawbacks such as unequal participation and lack of uniformity in public deliberations, with elites and other powerful social and economic actors generally holding sway. The phenomenon of fake news, online disinformation, the issue of digital divide, creeping state repression and COVID-19 restrictions during the 2020 election period have all combined to hamstring the Ghanaian new media which is currently at the center of a seemingly endless process of structural transformation.

JIRFAN DAWANTO (4517035005).  The Effect of Giving Amino Acid Solutions Based  on BSF Maggots (Hermetia Illucians) with Different Concentrations into the Feed on the Percentage of Breast and Back of KUB Chickens. (Under the guidance of Asmawati Mudarsep as the main guide and Muhammad Idrus as the aggota guide).

KUB chickens are widely kept by farmers because they have fast growth.  The current constraint on native chicken farming is the high price of feed raw materials.  Therefore, Maggot from  the Black Soldier Fly fly (Hermetia Illucens) is one of the best alternatives as a mixture of chicken feed because it has a nutrient composition that is almost the same as fish meal.  Based on this, this study aims to determine the Effect of Giving Amino Acid Solutions Based  on BSF Maggot (Hermetia Illucians) with Different Concentrations into Feed on the Percentage of Breast and Back of KUB Chickens.

This study used the DOC of 96 KUB chickens and was kept for 60 days with a cage map of 16 plots and each plot consisted of 6 KUB chickens. Feed used at the age of 1-30 days is given BP-11 granules, then at the age of 31-60 days using mixed feed by adding a fermented Maggot-based amino acid solution  arranged according to treatment.

The treatment used is the administration of BSF maggot-based amino acid solutions  , namely: P0, P1 (15 ml), P2 (30 ml), P3 (45 ml)

The results of the analysis of various doses of Maggot amino acid solution as an additive to mixed feed showed results that had no real effect (P>0.05) on the percentage of breast and back of KUB chickens. However, the administration  of Maggot amino acid solution  as an additive to mixed feed did not reduce the weight of KUB chicken breasts and buttocks and showed good performance
Flexion Angle Estimation from Single Channel Forearm EMG Signals using Effective Features
Authors: HAMZI Maroua , BOUMEHRAZ Mohamed , HASSANI Rafia
Published: September 2023

Electromyography (EMG) records the electrical activity generated by skeletal muscles, offering valuable insights into muscle function and movement. To address the complexity of EMG signals, various signal analysis methods have been developed in the time and frequency domains for engineering applications like myoelectric control of prosthetics and movement analysis. In this study, EMG signals were acquired from ten healthy volunteers in different forearm positions using a Myoware Muscle Sensor and MPU6050 board. From each EMG signal, root mean square (RMS), standard deviation (STD), and mean absolute value (MAV) were computed and selected as representative features. These features were then fed into an LDA classifier to estimate forearm flexion angles. The study aims to compare the effectiveness of features calculated from the EMG signal and those derived from its discrete wavelet decomposition. The experimental results demonstrate the proposed method's efficiency in estimating forearm flexion angles using a single channel of EMG signals, achieving an average classification accuracy of 97.50 % across four gesture classes.

Authors: Aziz Tanzilul , Mukhsin Abd.
Published: September 2023

This article aims to analyze the effectiveness of Law no. 16 of 2019 in reducing the rate of early marriage. Indonesia is a country whose population is relatively large in early marriage. Early marriage is legal if the terms and conditions are met. Ironically, in line with the rise in early marriage, the divorce rate has actually increased. Furthermore, divorce plaintiffs are teenagers who initially married at an early age. The urgency of this research is to review the effectiveness of the law in reducing the number of early marriages in Hamparan Perak District. This article uses a qualitative method with a normative juridical approach. The data collection techniques used were interviews, observation and documentation. The primary data source in this research is the results obtained through interviews and observation, while the secondary data used is a literature review. The results of the research show that in Hamparan Perak District, changes to this law were effective because they were able to reduce the number of early marriages. However, the author still found several young couples who chose to get married. This problem can be suppressed through strict regulations and requirements. The change in the law regarding the age of marriage is very effective in reducing the number of early marriages in Hamparan Perak District

Published: September 2023

A physical and mathematical model of hybrid detonation of a mixture of hydrogen — oxygen — argon — aluminum particles is presented. Using this model, the influence of aluminum particles on the process of detonation propagation in a channel with expansion was studied. To speed up the results, the numerical model was extended using the Open MP libraries. As a result, it was found that the mode of propagation of hybrid detonation is affected by both the loading and the size of the particles. In general, the hybrid mixture is more resistant to changes in the geometry of the area to be filled.

Published: September 2023

In the article, an extraordinary phase transition in thin antiferromagnetic films was investigated by computer modeling. The simulation uses the Ising model and Metropolis algorithm. Cubic crystal lattice epitaxial films containing multiple monoatomic layers are studied in the paper. The difference in the value for the exchange integrals in the bulk and on the surface of the film is a condition for the appearance of surface and extraordinary phase transitions. The film shall contain at least eight monoatomic layers for appearance of surface and extraordinary phase transitions. The extraordinary phase transition is investigated at different film thicknesses. Magnetic susceptibility demonstrates a logarithmic dependence on Neel temperature near the phase transition point. The dependence of the critical exponent of magnetic susceptibility on film thickness is calculated for the logarithmic phase.

Published: September 2023

The increasingly competitive business world makes it crucial to protect aspects of information that support the course of business activities. Unfair business competition results in the leaking of information related to Trade Secrets. This article was written to find out what efforts should be made to protect trade secret rights. The type of writing of this article is Critical legal studies with a normative juridical approach where law is conceptualized in statutory regulations to serve as a guide for human behavior. In the case that occurred between CV Bintang Harapan and CV Tiga Putra Berlian, it shows that the contents of the Trade Secret Law regarding confidential matters cannot accommodate problems that occur in the field. Apart from that, there is no legal protection that can direct to handling or prosecution of trade secret violations so that they can operate across sectors. The government as a regulator and policy maker must more comprehensively set appropriate strategies to develop regulations on Law Number 30 of 2000 concerning Trade Secrets so that they can become a benchmark for appropriate Trade Secret protection.

Authors: EGBARA Edward A. , OFODU Henry I. , ONUOHA Stella N.
Published: September 2023

Urbanization is not a recent phenomenon neither is it peculiar to any society. It is a global phenomenon, a trans-generational process that is inevitable and never ends. Urbanization brings with it possibilities of improved access to housing and also posed challenges to urban housing in many countries. The present study has been therefore motivated by the inadequacy in housing facility in relation to the ever-increasing urban population in Enugu Urban. The broad objective of the study was to examine the effect of urbanization on housing facility in Enugu Urban, Enugu State of Nigeria. The specific objectives are to ascertain the effect of urban spatial structure on housing quality in Enugu Urban; and determine the effects of population growth on housing affordability in Enugu Urban, Enugu State of Nigeria. The study adopted a descriptive survey design. The population of the study was 969,074, comprising 774 staff of Enugu State Housing Development Corporation and 968,300 residents of urban areas in Enugu State. The sample size of 400 was determined using Taro Yamane formula. The purposive sampling technique was used for the selection of the respondent. The data collected were presented and analyzed using mean score and standard deviation, while the hypotheses were tested with t-test statistical analysis at 0.05 level of significance. The study revealed that urban spatial structure has significant negative effect on housing quality in Enugu Urban (χ2 cal. of 30.74 > χ2 tab. of 9.49). It was also discovered that the population growth has significant negative effect on housing affordability in Enugu Urban, Enugu State of Nigeria ((χ2 cal. of 19.65 > χ2 tab. of 9.49). It was concluded that the extent of the housing shortage in Enugu urban areas is enormous. The inadequacies are far-reaching and the deficit is both quantitative and qualitative, but not insurmountable. Based on these findings and conclusion, the study recommended for urgent multi-faceted intervention to address the housing deficit both qualitatively and quantitatively by adopting a pro-poor housing development strategy through public-private partnership. The study also recommended that the development of further estates should henceforth emphasize on low-income housing to create more houses affordable by the low income earners in Enugu urban.

A educação especial, no viés da educação inclusiva, perpassa diversos aspectos de análise e meandros de reflexão histórica e contextual, muitos dos quais destacam-se frente à construção de políticas e práticas educativas que busquem integrar, agregar e valorizar os espaços, individualidades, personalidades e outras características que constituam o indivíduo com limitação de suas capacidades físicas, cognitivas ou até mesmo mentais. No Brasil, é significativa a parcela de alunos especiais que, à guisa de suas necessidades, nem sempre são estimulados, orientados e assistidos como versam os direitos e garantias atribuídos a eles nos ambientes escolares. Ademais, o objetivo do presente estudo foi de discutir a educação especial na perspectiva da educação inclusiva, analisando o cenário de desafios e potencialidades. Em termos metodológicos, procedeu-se à pesquisa bibliográfica nos principais sítios de busca, a partir do uso de descritores temáticos, considerando os estudos publicados entre os anos de 2018 e 2023. Esta pesquisa foi, ainda, dirigida por meio de base qualitativa, exploratória e explicativa. Concluiu-se que existem, efetivamente, proposições que tornam a educação especial e inclusiva construtiva do ponto de vista dos avanços e desenvolvimento dos estudantes pertencentes a esta classe. Por outro lado, existem desafios que se colocam como verdadeiros impeditivos para fomentar ações que fortaleçam esse cenário, a exemplo de baixa infraestrutura de atendimento especial, docentes sem capacitação e preparação adequadas, alta evasão escolar e índices de reprovação dos alunos, carência de material didático e baixa acessibilidade dos alunos a recursos tecnológicos de qualidade e especializados às suas limitações.

Background. Universal newborn hearing screening is mandated in the Philippines through the Universal Newborn Hearing Screening and Intervention Act of 2009 (RA 9709). Newborn hearing screening (NBHS) centers are required to perform screening tests, compile and submit data on screened newborns, and advise parents on the subsequent steps after NBHS.Objective. The study aimed to conduct a survey of the implementation of the Universal Newborn Hearing Screening and Intervention Program (UNHSIP) in the different regions of the country; and assess the information technology (IT) capabilities of hearing centers.Methods. Fifty-one NBHS centers across twelve regions were surveyed through on-site inspections in 2016. Data was gathered on the centers’ testing capability, staffing, access to specialists, use of local protocols, connectivity, and IT capabilities.Results. All surveyed centers followed the recommended protocols of the Manual of Operations of the Universal Newborn Hearing Screening and Intervention Act of 2009 (RA 9709). Among the 12 regions visited, only five (41.67%) had Category C centers with confirmatory testing and early amplification services as recommended. Majority of facilities (96.1%) were staffed by trained and certified personnel. A small percentage had access to subspecialists such as clinical audiologists (39.2%) and speech-language pathologists (23.5%). All facilities had computer access, but only 58.8% had internet access. Majority (94.1%) of the centers visited were not using the recommended data submission methods, specifically the use of registry cards and the online registry. Only 27.5% of centers had data on newborns who underwent confirmatory testing or early intervention.Conclusion. Facilities were found to be compliant to NBHS screening protocols and majority complied with certification requirements for staff; but were found to be non-compliant with use of registry cards or the online registry. Majority of centers were able to contact the parents of neonates who did not pass newborn screening, but had no system to track outcomes. Lack of confirmatory and early intervention services in identified areas emphasize the need for development of regional centers. It is recommended that measures to improve the utilization of the online registry are taken.

Objective. Newborn hearing screening (NHS) in the Philippines has been mandated by law since 2009. However, lack of awareness and knowledge about NHS remains a challenge, especially among healthcare providers. This paper describes the pilot implementation of a computer-based training (CBT) course on NHS and teleaudiology among primary healthcare providers (PHCPs) in rural Philippines.Methods. A four-module web-based training course on newborn hearing screening and teleaudiology in an online learning management system (LMS) was field-tested among PHCPs from eight rural communities in the Philippines. Participants were given four weeks to complete the course.Results. Forty-two PHCPs participated in the CBT. Thirty-four (81%) completed the whole course (mean attrition rate of 4.8% per module) at a mean duration of 10.2 days. Baseline data shows that participants had no NHS training, although the majority (83%) had information and communications technology (ICT) training. Comparison of preand post-test mean scores showed a 24.0% (p<0.001) significant increase in the post-test in all four modules. Passing rates (i.e., score ≥70%) from pre- to post-test increased by 54.6% (range: 38-80% increase). Usability of the CBT was rated high with a mean score of 4.32 out of 5 (range: 4.13 to 4.47), covering all eight parameters. Participants expressed general satisfaction and apositive attitude on CBT to improve knowledge on NHS and teleaudiology.Conclusion. Even in low resource settings where gaps in ICT infrastructure exist, eLearning can be used as an alternative approach to increase awareness and support training of healthcare providers on newborn hearing screening.
İran Sinemasında Minimalizm Örneği

Published: September 2023

Kökenleri 1960’lara dayanan ve ilk olarak Amerika’da yaygınlaşan minimalizm sanatta resim ve heykel alanında ortaya çıkmıştır. Minimalizm, çeşitli sanat dallarında kendine özgü kullanımlar göstermiş ve genel itibari ile mevcut akımlara tepki olarak ortaya çıkmış bir sanat akımıdır. Minimalizm, sadelik ve nesnelliğin ön planda olduğu bir akımdır. Minimalizm ya da minimal sanat teriminin sanat tarihi literatüründeki ilk kullanımı üzerinde çeşitli bilgilere rastlamak mümkündür. Bu terimi günümüzde karşımıza çıkan anlamında ilk olarak kullanan isim Richard Wollheim olmuş ve Minimal Sanat kavramını 1961 yılında içeriği en aza indirgenmiş sanat anlamını karşılamak üzere üretmiştir. Barbara Rose’un ABC Art başlıklı yazısında yeni bir sanat eğiliminden söz ederken kullanmış olduğu minimum sözcüğü, minimalizm kavramına hayat verdiği kabul edilen ilk adlandırmalardan biridir. Minimalizmin doğmasına gerçekçilik, nesnelcilik, işlevselcilik ve sadecilik gibi akımlar öncülük etmiştir. Dünyada ve ülkemizde bu kavrama ait ilk sinema örnekleri Robert Bresson, Yasujiro Ozu, Semih Kaplanoğlu, Nuri Bilge Ceylan gibi yönetmenlerin filmlerinde görülmüştür. Bu filmler; minimal anlatı yapısına sahip filmler olarak daha sonradan geçmişe yönelik inceleme yapılarak minimalizm ile ilişkilendirilmiştir. İran’da Abbâs Kiyârustemî ve Sohrâb Şehîd-i Ṣâliṣ bu akımın iki önemli öncüsüdür. Bu çalışmada genel olarak minimalizmin tanımı verilecek, sinemada minimalizm ve İran’daki izdüşümlerinden sonra niteliksel içerik analizi yöntemiyle İran’ın önde gelen yönetmenlerinden Sohrâb Şehîd-i Ṣâliṣ’in içinde minimalizmi barındırdığı için, Yek İttifâḳ-i Sâde (Basit Bir Olay) ile ‘Abbâs Kiyârustemî’ye ait Ḫâne-yi Dûst Kocast? (Arkadaşımın Evi Nerede?) filmleri minimalist sinema bağlamında değerlendirilecektir.

Authors: Osintseva Maria , Ishutin Ivan
Published: September 2023

Geographical and climatic features of the Kemerovo region (Kuzbass, Russia) determined the modern geological and geomorphological structure of the territory, as well as a characteristic pattern in the distribution of mineral deposits. The purpose of this work was to study the geomorphological and hydrological features of the Kemerovo region. Atmospheric circulation, relief, and vegetation are the climate's main factors. The combination of these factors forms the climatic characteristics of the region. Soils in open areas (meadows, hayfields) occupy a small area and have high economic and ecological value. Most of the forest is not affected by economic activities. The exception is disturbances in the territories affected by logging and mining enterprises, which especially affect the air and water quality in the region. All the obtained results of the assessment of the geomorphological and hydrological condition of the Kemerovo region should be used when planning further experiments on the stages of technical and biological reclamation of disturbed lands of mining enterprises to restore vegetation cover and the primary state of soils.

In this paper, a way for sleuthing underground cable fault distance locator is done by using microcontroller. The target of this project is to work out the gap of underground cable fault through base station in kilometers. It uses the straight forward conception of ohm’s law, voltage drop can vary counting on the length of fault in cable, since the current varies. A group of resistors are used to represent the length of cable in kilometers and a dc voltage is fed at one end and the fault is detected the change in voltage using analog to voltage converter. The fault occurring at what distance is shown on LCD which is interfaced with the microcontroller that is used to make the necessary calculations.
