Railway crane platform stabilization system
Authors: Potakhov D. A. 
Published: June 2021

When operating a railway crane in curved sections of the track, derailment of wheelsets of the crane bogies from the rail track when it is displaced during hanging on the outriggers, wheelset of the bogie missing the rail track after the work has been completed or the crane has been down from the outriggers, which significantly affects performance of loading and unloading operations. One of the reasons for the occurrence of such dangerous situations is the not strictly horizontal position of the non-rotating platform of the railway crane.Railway cranes are part of recovery trains designed to eliminate the consequences of rolling stock derailments. A priority for recovery trains is to reduce the time it takes to eliminate the consequences of traffic accidents, which can be achieved through the use of new or improved devices or methods.The article describes a system of automatic stabilization (leveling) of the platform of a railway crane (for example, EDK 500/1 crane type) when it moves in curved sections of the track (the motion of a railway crane at relatively low speeds (up to 50 km/h) is considered).In order to study the modernized technical system (a crane equipped with an automatic platform stabilization system), its mathematical simulation is carried out. At the initial stage, a solidstate digital model of a railway crane in combination with a section of a railway track is created in the SolidWorks computer-aided design system; developed solid model is translated into the Sim- Mechanics MATLAB environment. Further, in order to improve the adequacy of modeling, the developed dynamic model is being finalized by integrating MATLAB program libraries (SimMechanics, SimHydraulics, Fuzzy Logic Toolbox, etc.) to take into account the interaction of elements of different physical nature. Results of modeling modernized technical system are presented, which confirm the advisability of using the stabilization system on railway cranes when passing curved track sections.

Authors: Sukoco Joko Eddy , Sutanta Heri 
Published: June 2021

Batas wilayah merupakan informasi geospasial dasar yang penting dan berguna dalam pembangunan suatu wilayah. Kabupaten Tabalong telah melaksanakan kegiatan penetapan dan penegasan batas desa dengan mengesahkan batas desa definitif sebanyak 117 dari 131 desa/kelurahan. Terdapat 51 desa yang berbatasan dengan daerah (kabupaten/provinsi) lain. Berdasarkan hierarki peraturan perundang-undangan, segmen batas desa yang berbatasan dengan daerah lain harus sesuai dengan segmen batas daerah yang ditetapkan oleh Menteri Dalam Negeri. Penelitian ini bertujuan untuk mengevaluasi penetapan batas desa definitif yang berbatasan dengan daerah lain pada tahun 2012-2020. Metode penelitian yang digunakan adalah metode analisis geospasial. Teknik pengumpulan data pada penelitian ini dilakukan dengan studi dokumen data sekunder dari instansi terkait. Metode analisis geospasial menggunakan sistem Informasi Geografis (SIG) yaitu teknik tumpang susun terhadap data-data geospasial format digital. Teknik analisis terebut digunakan untuk menganalisis perbedaan posisi segmen batas, pergeseran segmen batas dan perbedaan luas wilayah. Hasil penelitian menunjukan terdapat 14 dari 51 desa yang mengalami perbedaan posisi segmen batas wilayah dengan pergeseran segmen maksimal batas berada pada rentang 35 – 4.300 m. Perbedaan posisi segmen batas juga mempengaruhi luas wilayah Kabupaten Tabalong, dimana terdapat perbedaan luas berdasarkan Perbup dan Permendagri sebesar 1.415,63 hektar. Penetapan lebih awal batas desa yang berbatasan dengan daerah lain dibanding penetapan batas daerah serta perbedaan sumber data segmen batas yang digunakan berpotensi menghasilkan perbedaan posisi segmen batas dan luas wilayah. Berdasarkan hasil ini, evaluasi terhadap penetapan batas desa definitif yang berbatasan dengan daerah lain perlu dilakukan, untuk memastikan kualitas informasi batas wilayah yang handal dan dapat dipertanggungjawabkan.
Las redes sociales y su relación con la función del comunicador político
Authors: Vásquez-Rizo Fredy Eduardo , Murgueitio-Echeverri Melissa , Jiménez-Trochez María Alejandra 
Published: June 2021

Este artículo tiene por objetivo evidenciar la importancia que tienen las redes sociales en el escenario político actual como herramientas comunicativas fundamentales para la labor del comunicador político, quien debe considerarlas en el diseño y desarrollo de una completa estrategia de comunicación política, es decir, como instrumentos complementarios a los medios de comunicación tradicionales asociados a dicho contexto y a su profesión. Para ello, se utiliza una metodología mixta, descriptiva y exploratoria que se basa en las técnicas de observación, encuesta y entrevista (no estructurada) para poder demostrar la crucial relación que actualmente existe entre las redes sociales y la comunicación política. En este contexto, las redes sociales son un medio estratégico de comunicación y el éxito de una campaña política. Para evidenciar esta relación, se emplearon tres etapas: 1) exploración de documentos y comportamientos ciudadanos en torno al uso de las redes sociales como mecanismo político; 2) análisis de percepciones de expertos en el tema; y 3) correlación de la exploración y análisis anteriores para la generación de resultados y conclusiones. Lo anterior demuestra el interés que existe por este nuevo espacio de contienda electoral que se asocia a la virtualidad, el cual se debe considerar y analizar para comprender el rumbo que está tomando este importante proceso de participación social, así como aprovecharlo para alcanzar el éxito político presente. En ste sentido, se concluye que las redes sociales son hoy un medio de comunicación trascendental, el cual se debe articular a las maneras tradicionales de hacer política y tener en cuenta necesariamente en esta nueva realidad.

Published: June 2021

Introducción: la enfermedad de Caroli es un trastorno congénito poco usual, el cual cursa con dilatación segmentaria multifocal de los conductos biliares intrahepáticos. Fue descrita por Jacques Caroli en 1958 como una dilatación sacular, segmentada o fusiforme de los ductos biliares intrahepáticos.
Objetivo: caracterizar a la población que ha padecido la enfermedad de Caroli.
Metodología: Revisión sistemática de la literatura.
Resultados: se analizaron 66 artículos, el grupo de edad más afectado es los menores de 10 años, en el que se evidenció una mayor prevalencia en varones, y se encontró asociado con otras comorbilidades como el riñón poliquístico (20 %). La manifestación más frecuente fue la hepatomegalia (44,7 %), seguido de la fiebre (42,4 %) y el dolor abdominal en el hipocondrio derecho (41,2 %). Como método diagnóstico más utilizado se encontraba la resonancia magnética (73,8 %); dentro de los hallazgos predominó la dilatación intrahepática (76,5 %) y el manejo más empleado fue la antibioticoterapia para tratar las recurrencias por colangitis.
Conclusión: la enfermedad de Caroli tiene una baja prevalencia, se presenta con mayor frecuencia en el continente americano, afecta principalmente a la primera década de la vida, tiene predilección por el sexo masculino y se caracteriza por una dilatación de los conductos intrahepáticos que puede afectar a otros órganos como los riñones, lo que produce quistes renales.
L'importanza del comparto socio-economico per uno sviluppo sostenibile: applicazione di un aeroporto
Authors: Martino Catello Di , Calicchio Francesco 
Published: June 2021

Nel corso del tempo e soprattutto dall’introduzione del concetto di
sostenibilità, il comparto socio-economico e le leggi che lo governano
rientrano in pieno nella tematica, divenendo elemento essenziale ed
imprescindibile.
Per l’assetto
economico, la relazione con le altre componenti è determinata
dall’interferenza reciproca tra le caratteristiche delle componenti
ambientali (stato di qualità dell’aria, qualità delle acque,
caratteristiche del suolo, ecc.…) i fattori ambientali
individuati (rumore, vibrazione, traffico, radiazioni, rifiuti, energia,
ecc.) e le caratteristiche del sistema produttivo. Le caratteristiche
delle altre componenti e degli altri fattori ambientali possono infatti
condizionare la sostenibilità ambientale del sistema produttivo, così
come il sistema produttivo può condizionare la sostenibilità ambientale
(ad esempio, presenza di attività industriali che comportano rilevanti
emissioni inquinanti in atmosfera condizionerà lo stato di qualità
dell’aria).

Published: June 2021

SUMMARY
The two-step approach of applying hydrofluoric acid followed by silane is deemed the gold-standard surface treatment protocol before bonding to glass ceramics. Given hydrofluoric acid is a toxic conditioning agent and with the intention to simplify this step, the dental company Ivoclar Vivadent (Schaan, Lietchtenstein) released a self-etching ceramic primer, Monobond Etch & Prime in 2015, claiming that hydrofluoric acid and silane application would no longer be required prior to luting glass ceramics. Therefore, this clinical case report and retrospective analysis describes the replacement of unsatisfactory anterior veneers due to clinical failures for new feldspathic glass ceramic veneers, using the aforementioned self-etching ceramic primer. After two years, feldspathic glass ceramics presented satisfying clinical performance with absence of debonding, tooth sensitivity, recurrent carious lesions, or marginal infiltration.
Imparcialidade, autoritarismo líquido e exceção na Operação Lava Jato
Authors: Serrano Pedro Estevam Alves Pinto , Bonfim Anderson Medeiros , Serrano Juliana Salinas 
Published: June 2021

A vulgarmente conhecida como “Operação Lava Jato” insere-se no contexto dos processos penais de exceção, bem como na materialização da presença do Estado autoritário no interior das rotinas democráticas. Referida matéria é comumente subestimada no âmbito da teoria geral do Estado e do processo penal, nos quais são escassos os estudos questionadores da concretização, ao menos na sua acepção plena, do Estado de Direito nos procedimentos e processos democráticos e de persecução penal. Tendo em vista, por um lado, a centralidade assumida pela “Operação Lava Jato” nas pautas do Judiciário brasileiro e, por outro, a premente necessidade de aferir adequação dos seus procedimentos e a justiça dos seus produtos, realizamos, após uma breve incursão nos aspectos propedêuticos da teoria da exceção e do cotejamento dos seus aspectos históricos e teóricos, uma análise do princípio da imparcialidade inerente ao exercício da jurisdição sob seus corolários objetividade ou juridicidade, isenção, neutralidade e transparência. O citado conteúdo dogmático extrai-se da nossa Constituição e do nosso Código de Processo Penal, mas também da Declaração Universal dos Direitos Humanos, do Pacto Internacional sobre Direitos Civis e Políticos e da Convenção Americana de Direitos Humanos, o Pacto de San José da Costa Rica. Ao final, constatamos haver reiteradas violações ao princípio da imparcialidade no âmbito da “Operação Lava Jato”, isso através da produção de medidas de exceção que se traduzem em esvaziamento do sentido dos direitos fundamentais mais elementares ao processo penal contemporâneo.
