Introduction: The lack of a permanent incisor not only generates an adverse effect on facial aesthetics but also alters its function, especially the incisor guidance. Upper incisors can suffer mechanical blockage or change in their eruption due to a supernumerary tooth, a blow or another factor. The treatment of choice is orthodontic-surgical. The prognosis depends on the age, tooth position, morphology, size, root maturation and traction method. Knowing the use of an orthodontic appliance, which is easy to handle and can be used from an early age, will be of valuable contribution. Objective: To show the successful use of a cantilever to enable orthodontic traction of an impacted incisor in a horizontal position. Case presentation: Eight-year-old patient with class I malocclusion, specimen 2.1 retained in a horizontal position, presence of supernumerary tooth and persistence of specimen ...

The research analyzes the Twitter network made up of users and their interactions during the Conference of the Parties (COP) COP15 held in Montreal from December 7 to 19, 2022. The main objective is to measure the characteristics of the network and identify the key players in the conversation and the main topics addressed. We also sought to recognize if there was any relationship between the format of the messages and the level of engagement. To carry out the analysis, we used a methodology that combined quantitative and qualitative social network analysis techniques. The results suggest that communication through Twitter was a key factor in the successful mobilization of the environmental movement during COP15 and in raising awareness of the need to take concrete actions to address climate change. Likewise, the highest engagement was generated by mostly critical and urgent messages, foc...

Lima experienced in August 2016 a massive mobilization against violence against women. From different theoretical approaches (frustration, mobilization of resources, collective action and political opportunity) an attempt was made to explain these events; however, few focused on the framing approach as an instrument of social mobilization. Thus, collective action frameworks are action-oriented sets of beliefs and meanings that inspire and legitimize social movement organizing activities and campaigns. We see that social movements seek to build a discourse through frames, which give them the opportunity to sustain the movement, or, as far as possible, to add a greater number of followers and seek solutions that benefit them. To do this, we start from the question: What frames were the most important in the Facebook managed by the collective “Ni Una Menos Peru: they touch one touch all...

The author proposed a new seismic response control system using a block and tackle (hereinafter, referred to as a dynamic pulley damper system) developed especially for the high-rise buildings. The proposed system has a configuration where a damper is installed on the track of the cable-stayed wire, amplifying the amount of movement of the wire by using a movable pulley that increases the damping effect to reduce the vibration of a building. we apply this system to connect the core structure (parking tower) and the surrounding frame (housing part) of a high-rise building. This system aims to reduce the earthquake response of the building by the force of the damper attached to the core structure. To verify the effectiveness of this response control system, two types of shaking table tests were conducted; one is the large-scale shaking table test using a magnetic damper, an-other one is th...

In this work some refl ections are exposed that arise from the realization of an ethnography in a socioterritorial movement of environmental character that resists the current agrarian model in a medium-sized Argentine city. In addition to conducting a brief tour of theoretical concepts central to research such as "socio-territorial movements" and "identity", we are dedicated to unraveling the details of ethnographic work describing in detail the implementation of the techniques used (observation participant and interviews), their potential and risks. At the same time, we deepened the tensions that were faced during the research process, while emphasizing refl exivity as an essential tool of the social researcher.

Miniscrews offer the possibility of performing dental movements, minimizing unwanted side effects, and enhancing effectiveness. Extra-alveolar miniscrews are ideal as they provide excellent primary stability and avoid anatomical structures. However, in some cases, the primary stability is lost before achieving the success of the mechanics used and thus, the most likely causes of failure should be determined. The purpose of this review was to analyze the success rate of infrazygomatic miniscrews, considering their design and the insertion techniques used. Data collection of this literature review was carried out by searching PubMed, Wiley, Google Scholar sites, SCIELO, Elsevier, and Dialnet for publication made from 2003 to June 2022. The search was carried out on June 10th, 2022, and the following keywords were used; infrazygomatic crest, miniscrews, anchorage, and stability. Different t...

This article presents different approaches to user interface design through machine learning techniques. It reviews various approaches to interface design, such as combinational optimizers, frameworks, and free-of-text interface design. Moreover, it shows how interface design with machine learning techniques is based on usability and user experience (UX). Likewise, the design process uses interactions stored in persistence systems or databases, which are then analyzed with machine learning techniques. Another design approach uses sketches and graphic layouts and, after evaluating their usability, uses image recognition algorithms to generate the interfaces; these designs are generally for mobile devices. Some techniques also analyze usability but focus more on the user’s bodily functions (movement, biological functions such as blood pressure, heartbeat, etcetera); this data can also be...

This study was designed to assess the susceptibility of turtle-doves (Eupelia cruziana) to Newcastle virus. A group of 15 turtle-doves was inoculated with a velogenic viscerotropic strain of the Newcastle virus, and a group of 15 was used as control. Both groups were raised in the same environmental conditions and were fed with similar feeds, but kept separate. Clinical signs and mortality were recorded. Blood samples were tested by the hemaglutination inhibition technique and tissue samples were collected for virus recovery and histological studies. From the inoculated group, 6 birds showed nervous signs like head tremors, neck torsion and uncoordinated movements, and three of them died. Macroscopic lesions were observed on the nervous system. Histological lesions were observed in the brain, and in lungs and tracheal epithelium. An increase in the antibody titers was observed at the 7th...

Se sabe que los articuladores son aparatos destinados a reproducir los movimientos y posiciones maxilomandibulares estáticas y dinámicas de una persona, debido a ellos hay que tener en cuenta el nexo que existe entre estos dispositivos y las relaciones intermaxilares, las cuales son necesarias conocer, para que el clínico pueda manipular los articuladores con éxito y pueda tener un buen resultado en los tratamientos que realice. El articulador es un instrumento imprescindible para trabajar a un cierto nivel. Estos instrumentos surgieron ante la necesidad de poder imitar los movimientos mandibulares fuera de la boca del sujeto. Es considerado como un dispositivo mecánico con el que podemos relacionar los modelos de la arcada dentaria de los pacientes para poder realizar procedimientos de diagnóstico y terapéutica fuera de la boca, y que utiliza los arcos faciales para transferir el...
