Periodontal status of the second molar adjacent to the third mandibular molar
Authors: Luzuriaga Katherine , López Jurado Santiago
Published: November 2020

Third molars have an unusual eruption pattern. Studies suggest that, due to the position and angulation of these, various pathologies could occur in the adjacent molars, such as periodontal problems and the appearance of distal caries. The objective of this work is to describe the periodontal status of mandibular second molars adjacent to mandibular third molars. For this, a descriptive transversal study was carried out. We worked with a sample of 277 patients that went to the Dental UCSG Clinic to have their third molars extracted in the period A-2018. An intraoral clinical examination was performed, and the following variables were observed: probing depth, gingival state, and presence of caries in mandibular second molars. In addition, panoramic x-rays of the patients were reviewed to determine the position of the third mandibular molar and the level of the distal bone crest of the second molars. The results showed that the depth of distal probing of the mandibular second molars were normal (from 1 to 3mm) in 31% of the cases, while in 69% depths greater than 3mm were found. Regarding the presence of bone loss, in 43% of the cases there was no loss, in 35% of the cases there was a slight loss, 22% presented moderate loss and only 1% had severe loss. The presence of mandibular third molars significantly affects the periodontal status of the adjacent second molar, which can lead to periodontal pockets, bone los sand caries in their distal area.

Peranan wanita dalam Islam dan feminisme barat
Authors: Hanim Midah Hamidah
Published: November 2020

The purpose of this study is to determine the role and rights of women in Islamic and Western views. Islam is a grace to all nature and although we know that women are created from male ribs, Islam never states that women’s degrees are below men. The methodology used literature studies. As for the research results that the role of women is said to be important because of the many heavy loads it has to deal with, even the burdens that men should have been imposing. Women have equal and equal rights in Islam in contrast to those prosecuted by Western women who demand equality and identification between men and women in every respect. The point of departure they use in this is that their rights must be equal, identical and comparable. There is no privilege and primacy for either of them. Equations are different from those of the identities. The gender equations many westerners had buzzed, evidently having permeated into the body of these Muslims' Muslims. They had been fooled by the thoughts of the westerners, not even a few of whom were to screech the thought. Natural law is fixed in nature to have regulated gender relations in society. So, when in society there is and there is a female subordination phenomenon, it is due to female biological factors. Some answers about the low role of public dissector women due to biological constraints, such as menstruation, pregnancy, childbirth, and breastfeeding. All of them became women's inhibitors to play a significant role in society.
Phonon investigation on the interaction of hydrogen on the missing row Pt (110)-(1x2) surface
Authors: Nguyen Hoa Van , Nguyen Phi Minh , Nguyen Thien Ngoc , Chau Dao Minh , Tran Hanh Thi Thu
Published: November 2020

The phonon calculations of hydrogen when adsorbed on the missing row Pt(110)-(1x2) surfaceusing the Ultrahigh Vacuum (UHV) model were studied. The calculations were based on a combinationof Density Functional Theory (DFT) and the approximation of hydrogen vibrations on thesurface. The harmonic vibration of H on the Pt surface was used for the calculation in this study. Atthe hydrogen coverage of 1ML for the model surface (when H completely covering the Pt surface),the interaction formed at the edge of the first layer (short bridge - R) was the most stable. The lessstable positions were recorded as the bridge position between two atoms on a horizontal row inthe second layer (trough - T), the top position of the second surface layer - fcc (F), the bridge positionof the second surface layer - hcp (F'), and the least stable position was the top position of thefirst layer (T'). When accounting the quantum calculation for the model, the adsorption energy ofhydrogen at the short bridge position increased by 90 meV, and the stable adsorption order of hydrogenchanged with the most stable positions ware R, T, T', F', F respectively. This demonstratesdthe significant influence of quantum effects on the adsorption model.
Revisiting Raúl Prebisch’s concept of crisis
Authors:   Universidad Autónoma del Estado de Morelos, México, Maria Victoria Crespo
Published: November 2020

This article offers a review and appraisal of the concept of crisis in the context of the remarkable trajectory and works of argentine economist Raul Prebisch. It argues that the crisis of the 1930s is the foundation of Prebisch’s theoretical proposal on dependency and development in Lat-in America. The crisis of 1929-1930 was the turning point that encour-aged him to revise and reinvent neoclassical economic theory, promote industrialization and import substitution, and, more importantly, to deeply restructure the role of the State in the region. The crisis leads to decision and action, and it implies and orientation towards the future, a new “horizon of expectations.” This horizon throughout the most part of the twentieth century in Latin America was development. The article also puts forward an interpretation of his program at the Economic Commission for Latin America and the Caribbean (ECLAC/CEPAL), also triggered by the crisis and oriented to the formulation of policies meant to overcome the crisis. Finally, the article shows how through his interactions with CEPAL sociologists, in particular José Medina Echavarría, Prebisch proposes a redefinition of his concept of crisis, shifting from an economic and junctural concept to a structural one: the crisis of peripheral capitalism
Chile and Pinochetism, a popular dictatorship?
Authors:   Universidad Diego Portales (Chile), Veronica Valdivia
Published: November 2020

This article probes into the “popular” dimension of the Chilean dictatorship headed by General Augusto Pinochet, also branded “pino-chetista”, in its efforts to seek legitimacy among elite and middle-class groups, but especially among shantytown dwellers. In this it exhibited some peculiar traits, which set it apart from other dictatorships in Latin America’s Southern Cone. Its hypothesis suggests that the social support received by Chile’s dictatorship and “pinochetismo” was actively sought by its ruling circles, mainly on account of two factors: the urge of military officers and civilian backers to legitimize the coup d’état and the regime it set up, and the process of personalization that overtook it and eventually led to “pinochetismo”. Its aim was a re-socialization of the popular classes, turning them into adherents of its neoliberal authoritarian project. This venture implied the formation of state apparatuses capable of penetrating the popular world.
Latin America through the vision of environmental geopolitics. A little about the history of the issue
Authors:   Institute of Latin America of the Russian Academy of Cience, Alexander Shinkarenko
Published: November 2020

In this article, the author touches upon the formation of ecological geopolitics and the role of Latin America in it. The socio-political processes that are currently taking place in the region focus on environmental problems, as well as the possibility of reducing the intensity of extractivistic initiatives. The relevance of the environmental discourses and the costs generated with the rental model of the economy, is characteristic not only of Latin America, but also other regions of the world. Nevertheless, it is here we can observe the active work of antiextractive movements to form a contemporary environmental agenda and search for models that are alternative to the current state of the world.
Russian diplomacy and the liberal Russian press on the events of the Ten-Year War of Independence (1868-1878)
Authors:   Institute of World History of the Russian Academy of Sciences, Liudmila Ivkina
Published: November 2020

The article examines Russia's position on the War of Independence in Cuba (1868-1878), which marked the beginning of a long process of national liberation. The tone of the reports of Russian diplomats from Spain and the United States was determined by the policy of neutrality and non-interference typical of Russia's foreign policy towards Spain after Аlexander II's accession to the Russian throne in 1855. Events of the liberation struggle of the Cuban people, methods and forms of liberation movement, the policy of the United States and Spain in relation to the war of independence in Cuba received coverage in the liberal Russian press, such publications as "World Illustration", "The Case", "The Herald of Europe". Articles and notes contained objective information about the events taking place in Cuba, expressed feelings of solidarity and support for the Cuban people, condemned the policy of Spain, which sought by any means to suppress the revolutionary process, criticized the Cuban policy of the United States, persecuted their vested economic interests and not interested in the independence of Cu-ba.

Published: November 2020

Most organizations exist in order to make a profit or economic gains. Thus economic performance of an enterprise is the ultimate of all the numerous activities that are undertaken. It is the bottom line of the value chain and the lifeblood of every business. Pharmaceutical companies in China also exist in order to make a profit, but profitability is not the only economic element that is of interest to pharmaceutical organizations. According to Schaltegger et al. (2014), economic performance relates to the manufacturing plant's ability to reduce costs associated with energy consumption, purchased materials, waste treatment, waste disposal, waste discharge, and fines or penalties for environmental accidents (Zhu et al., 2008a; Schaltegger et al., 2014).

The picture handling systems are helpful for some applications, for example, science, security, satellite symbolism, individual photograph, medicine, etc. The techniques of picture handling, for example, picture upgrade, picture division and highlight extraction are utilized for crack recognition system. This paper utilizes canny edge location strategy for segmentation. Canny strategy produces ideal data from the bone picture. The principle point of this examination is to recognize human lower leg bone crack from X-Ray images. The tests we lead show that the proposed framework is precise and ef?cient.
Sufrimiento, estados afectivos y dolor
Authors: Gayosso Cabello Efraín
Published: November 2020

En este texto desarrollo la idea que el sufrimiento no es lo mismo al dolor, no es una emoción y tampoco un estado de ánimo, pero sí es parte de la afectividad. La manera en que es parte de la afectividad es que está constituido por estados afectivos tales como emociones, estados de ánimo y dolor. Cabe destacar que estos estados no son necesarios para que haya sufrimiento, es decir, cuando una persona sufre, su sufrimiento no siempre está constituido por emociones, dolor o estados de ánimo. Estos estados a veces son constitutivos del sufrimiento, pero cuando hay sufrimiento al menos un estado afectivo de este tipo es constitutivo del sufrimiento. Además menciono que el sufrimiento a veces es una disposición y aclaro en qué sentido lo es. Así, distingo entre lo que constituye al sufrimiento y aquello que lo causa. Las causas del sufrimiento pueden ser diversas, pero me centro en dos que considero son importantes para entender al sufrimiento, estas son la enfermedad y la pérdida. Al final desarrollo un argumento sobre cómo el sufrimiento es distinto al dolor.

La cafeína es el psicoestimulante activo más consumido en el mundo. Disminuye la sensación de fatiga y la sensibilidad al dolor; además, estimula la actividad motora y genera una sensación de energía y un aumento en la capacidad para concentrarse. Objetivo: evaluar el efecto de la cafeína sobre el desempeño psicométrico en 14 estudiantes universitarios. Material y métodos: se utilizó el test de Terman-Merrill y fue aplicado antes y después de la prueba. Para la segunda medición, se formaron dos grupos de estudio, cada uno conformado por siete sujetos de manera aleatoria. A los integrantes del primer grupo se les dio 150 mg de cafeína y a los del segundo, 200 mg. Para evaluar los efectos se utilizaron las pruebas de Wilcoxon y U de Mann Whitney. Resultados: se observó que, tras la ingesta de cafeína, hay una mejora significativa en algunos parámetros de la cognición del test Terman-Merril, como son el vocabulario (p=0.029), síntesis (p=0.004), y abstracción (p=0.004). Se encontró que una dosis de 200 mg de cafeína ejerce mayor efecto sobre la capacidad de planeación (p=0.049) en comparación de la dosis de 150 mg. Conclusión: la cafeína (200 mg.) mejora significativamente algunos de los aspectos psicométricos del test Terman-Merril. LUXMÉDICA AÑO 15, NÚMERO 44, MAYO-AGOSTO 2020

Published: November 2020

La pandemia de COVID-19 evoluciona día con día y son cada vez más los países y personas infectadas en todo el mundo. Hasta el momento, no existe un tratamiento establecido para la infección. Ésta, provocada por el virus SARSCoV-2, tiene una elevada tasa de transmisibilidad de humano a humano y esto ocasiona que el número de casos sea muy elevado. Así mismo, el número de pacientes que desarrollan la enfermedad en su forma severa y que, por ende, requieren de hospitalización y apoyo ventilatorio, en algunos países ha rebasado a los sistemas de salud. Estos pacientes generalmente tienen estancias prolongadas en la UCI y en muchos de ellos es necesaria la valoración de una traqueotomía. En este momento no existen guías basadas en la evidencia para la realización de ésta y sólo existen recomendaciones y documentos de consensos de diferentes sociedades médicas. En el presente trabajo revisamos las guías nacionales e internacionales publicadas en MEDLINE y Google académico para documentar el consenso de éstas respecto al tiempo de realización de la traqueotomía y de las condiciones en las que la misma debe ser realizada con la finalidad de reducir el riesgo para el personal de salud que las realiza.

Published: November 2020

Introducción: existen estudios que indican que entre 50% y 71% de los hombres estaría interesado en usar un método anticonceptivo reversible. La búsqueda de un anticonceptivo masculino hormonal se ha visto obstaculizada por la falta de un andrógeno oral seguro y efectivo, que disminuya, interrumpa o afecte la calidad de los esper- matozoides. El objetivo de este estudio fue hacer una revisión de los nuevos métodos anticonceptivos con el fln de crear una perspectiva más amplia de las novedades en anticoncepción masculina en estudio. Metodología: se realizó una búsqueda en la literatura de las bases de datos en línea PubMed, EBSCO, BVS, Cochrane, el buscador de la UAA y Epistemonikos utilizando los siguientes términos MeSH en español e inglés: "anticonceptivos masculinos”, "anticonceptivos masculinos hormonales” y "anticonceptivos masculinos no hormonales”. Resultados: los anticonceptivos hormonales masculinos actúan a nivel del eje hipotálamo-hipóflsis- testículos, el cual se encarga de estimular la esteroidogénesis y la espermatogénesis. Los métodos no hormonales pueden actuar en cualquier punto de la espermatogénesis o pueden actuar a nivel de motilidad o transporte. La razón detrás de los anticonceptivos no hormonales es evitar el eje hipotálamo hipoflsario, evitando potencialmente algunos efectos secundarios asociados con las hormonas. Mencionar cuáles anticonceptivos se consideran dentro de los métodos hormonales y cuáles son los no hormonales. Conclusión: el reto de los anticonceptivos masculinos hormonales y no hormonales es demostrar un fuerte perfll de seguridad. Son necesarios estudios de todos estos anticonceptivos masculinos en población latinoamericana o mexicana. LUXMÉDICA AÑO 15, NÚMERO 45, SEPTIEMBRE-DICIEMBRE 2020, PP 37-54.

Microstructural Characterization and Mechanical Properties of Volcanic Tuff (Malatya, Turkey) Used as Building Stone for the Restoring Cultural Heritage
Authors: Maras Muslum Murat , Kose Mehmet Metin , Rızaoglu Tamer
Published: November 2020

Old stone buildings constitute a significant percentage of the residential buildings in many countries. These structures are highly vulnerable, and important losses in masonry structures occur even in moderate earthquakes. Therefore, safety evaluations of these structures have gained significant attention in recent years. In this study, the mechanical, physical and microstructural characteristics of tuff samples used in the old buildings were investigated in Battalgazi within the boundaries of Malatya Province during the Seljuk time. The characteristics of the building materials were examined in detail using in-situ and laboratory tests. Because adequate samples could not be obtained from the historical buildings, quarry areas with the same characteristics were identified. First, original building stone (OBS) used in construction was taken from fallen and unusable blocks. Then, the properties of the restoration building stones (RBS) brought from the quarries were investigated. The RBS samples were also examined using in the laboratory, and the mechanical and microstructural properties of the building components were determined. The dynamic and static moduli of elasticity were determined using ultrasonic pulse velocity and uniaxial compression test. The OBS and RBS samples yielded similar results after the microstructural analyses. Our results showed that the dynamic elastic modulus value was higher than the static elastic modulus value. The results revealed by both methods showed that the static and dynamic elastic moduli were closely linked. The OBS and RBS samples exhibited microlitic porphyritic and vesicular textures and nearly the same mineralogical and textural characteristics.

The aim of this comparative study was to evaluate the effectiveness of auto polymerized acrylic denture on oral mucosa. The total 40 partially edentulous patients were included in this study and randomly divided into two groups. Group A consisted of 20 patients and group B consisted of 20 patients who were attending in the Department of Prosthodontics and they were treated by auto polymerized and heat cure acrylic denture respectively. Follow up was done after 1 weeks and 4 weeks of insertion of denture. Data were recorded by using predesigned data collection sheet and analyzed by using SPSS. In case of autopolymerized acrylic denture, after 4 weeks of treatment most of the cases showed oral mucosal changes which could be turned to malignancy (p<0.5). But in case of heat cure acrylic denture satisfactory mucosal changes were not found. However, heat cure acrylic denture did not show any statistically significant difference (p>0.5). So it can be concluded that there is a direct adverse reaction between autopolymerized acrylic denture and oral mucosa.

Published: November 2020

The calcified root canals cause many problems during endodontic treatment due to difficulty in canal orifice location, negotiation, preparation as well as consideration of operating time. Most serious problem may arise during any phase of root canal treatment procedure even taking a lot of precaution. Partial or total obliteration of pulpal chamber or root canal space is the most common consequences of a tooth which is exposed to traumatic injury. The most common presentation of such a tooth is complete or partial loss of the pulp space radiographically and discoloration particularly yellow discoloration of the clinical crown. Around 7–27% of teeth having the feature of partial canal calcification shows features of pulp necrosis accompanied by radiographic signs of chronic periapical periodontitis. Very low numbers of teeth( 2-3%) may present with total obliteration of pulp chamber and the root canal system . Teeth with such features is challenging to provide a successful root canal treatment; . In this case report a 21 years old female patient attended with complaints of discoloration , mild spontaneous pain , and several episodes of gingival swelling with history of trauma four years back in her both maxillary central incisors. The case was evaluated clinico radiographically and the diagnosis was a case of calcification both maxillary central incisors. Root canal treatment to manage the calcified canals following conventional technique was planned . After treatment patient was free from subjective and objective signs and symptoms and she was advised for periodic follow-up

Ilmastodiskurssi Venäjän arktisella alueella
Authors: Yagodin Dmitry
Published: November 2020

Artikkelissa tarkastellaan, voisivatko vuonna 2016 Jamalin niemimaalla luoteis-Siperiassa ilmenneet pernaruttotapaukset haastaa Venäjällä vallitsevaa diskurssia, jossa mahdollisesti pernaruton ilmenemisen taustalla oleva ilmastonmuutoksen ongelma sivuutetaan. Artikkelissa pohditaan, miten mahdollinen haaste vallitsevalle diskurssille ilmenisi. Tutkimus perustuu rajattuun otokseen kansallisen ja paikallisen tason mediasisältöjä, joissa pernarutto liitettiin ilmastonmuutokseen. Analyysi hyödyntää poststrukturalistisen diskurssiteorian oletuksia sekä dislokaation ja diskursiivisen logiikan käsitteitä ja kohdistuu talouskehityksen ja ympäristön muutoksen suhteeseen alueella, joka on yhtä aikaa keskeinen Venäjän fossiilitaloudelle sekä haavoittuva ilmastonmuutoksen vaikutuksille. Tulokset osoittavat esteitä ja mahdollisuuksia ilmasto-oikeudenmukaisuuden toteutumiselle tässä viitekehyksessä. 

 

Poststructuralist discourse on climate justice in the Russian North

This study uses the case of the 2016 anthrax outbreak on the Yamal peninsula in north-western Siberia to discuss whether and how the incident could challenge the dominant discourse in Russia that neglects the problem of climate change – a potential cause of the outbreak. The study draws on a small sample of media materials that linked the incident to climate change on the national and regional levels. The analysis follows the premises of poststructuralist discourse theory and the concepts of dislocation and discursive logics to unpack the intricate relationships between the issues of economic development and environmental change in a region that is at once central to Russia’s fossil fuel economy and most vulnerable to the effects of climate change. The results point to the obstacles and opportunities for climate justice discourse in this context.

Published: November 2020

Artikkeli käsittelee autoritaaristen hallitusten ympäristösuhteita. Artikkelin tapaustutkimus käsittelee Unkarin kommunistisen hallituksen reagointia kasvaviin ympäristöongelmiin 1960-luvulla. Artikkelin tarkoituksena on selittää ympäristökriisin tärkeimpiä kansallisia tekijöitä erityisesti Borsodin teollisuusalueeseen liittyen. Ko. alueella luonnonvarojen käyttö aiheutti monimuotoisen ympäristökriisin, minkä ratkaisu vaati valtiotoimijoilta useita eri toimia.  Artikkelissa Unkarin tapaus asetetaan laajempaan kontekstiin: miten ja miksi autoritaariset hallitukset kuten Guatemalan ja Chilen juntat tai demokratiat kuten Länsi-Saksa käyttivät erilaisia teknologioita ja propagandaa luonnonvarojen säilyttämisen edistämiseksi. Artikkelin tarkoituksena on vastata siihen, kuinka ja miksi erilaiset lähestymistavat ympäristönsuojeluun epäonnistuivat erilaisissa poliittisissa järjestelmissä. Artikkeli pyrkii myös selittämään ihmisten ja luonnollisen ympäristön ristiriitaisia suhteita autoritaarisissa hallintojärjestelmissä.

 

Environmental protection in authoritarian systems

This article discusses the complex relationships between the natural environment and authoritarian governments via the study’s main case: the growing environmental problems of Cold War Hungary and the reaction to those issues by the country’s government. This study aims to shed light on some of the most important factors of the environmental challenges faced in one of the largest industrial areas of that country, the Borsod Basin. Here, the extraction of natural resources caused a complex environmental crisis that required substantial efforts from various state agencies. This article presents the Hungarian case in a broader context to study how and why authoritarian and democratic governments such as the Guatemalan and Chilean juntas and West Germany have used technology and propaganda to promote the conservation of natural resources. In conclusion, this article aims to explain how and why various approaches under various political and economic circumstances to mend the environment eventually failed.

This study produces a decision support system for selecting the location of the MSME service business in Alang-Alang Lebar Palembang. There are 2 methods used in this application, namely the Analytical Hierarchy Process (AHP) and the Weighted Product Method (WPM). AHP is used to determine the weight of the criteria and WPM is used to rank the location of the MSME service business. The criteria used in this SPK are rental fees (K1), renovation needs (K2), availability of clean water (K3), availability of electricity supply (K4), presence of asphalt roads (K5), parking space (K6), population density (K7 ), the presence of competitors (K8) and proximity to suppliers (K9). The AHP calculation results show that the rental fee has the highest weight, namely 0.35, which means that the level of importance of the rental fee is 35%. The WPM calculation results show that the location of the 8th MSME service business is the recommended location.
