Tip and Torque Accuracy According to the ISO 27020:2019 Norm in Currently Available Pre-Adjusted Orthodontic Brackets

Background: The precision of bracket manufacturing is fundamental to ensure the correct expression of the inbuilt information. The objective of this study was to determine the actual tip and torque values of a pool of stainless steel brackets, pre-adjusted according to the MBT prescription values, and to compare these actual values with those stated by the manufacturers in order to test their compliance with the tolerance limits reported in the ISO 27020:2019 Methods: A sample of 360 stainless steel brackets, from 12 different providers, were evaluated. All brackets had a nominal slot size of 0.022 in., belonged to the upper right central incisor, and were manufactured with the metal injection molding technique (MIM). For each provider, three different batches of the same bracket series were tested. A single-blind design was used for bracket coding. Results: Only five systems displayed torque mean values that matched the declared values (p > 0.05). Only one system did not respect the tolerance limits established in the ISO 27020:2019 norm. The tip values were different from those declared in seven of the assessed systems; however, none exceeded the tolerance limits. The inter-batch variability in most cases was not statistically significant. Conclusions: In most of the assessed systems, there can be a difference between the actual and the declared torque values, while tip information is usually accurately incorporated into the bracket slot. Lack of precision in the manufacturing process can reduce the efficacy of the appliance and force the clinician to compensate for dimensional inaccuracy through wire bending.

Individual cells traffic the Vasopressin 2 Receptor to their cell surface with different success

G protein coupled receptors (GPCRs) translate the actions of hormones and neurotransmitters into intracellular signalling events. Mutations in GPCRs can prevent their correct expression and trafficking to the cell surface and cause disease. Single cell subcellular localisation measurements reveal that while some cells appear to traffic the majority of the vasopressin 2 receptor (V2R) molecules to the cell surface, others retain a greater number of receptors in the ER or have approximately equal distribution. Mutations in the V2R affect the proportion of cells able to send this GPCR to their cell surface but surprisingly they do not prevent all cells from correctly trafficking the mutant receptors. These findings reveal the potential for rescue of mutant receptor cell surface expression by pharmacological manipulation of the GPCR folding and trafficking machinery.

Should we say "functional diversity" to refer to "disability"?

This article addresses "political correctness" (PC) regarding the rights of people with disabilities and specifically the state of the question in Spain. First, we focus on the expression itself and clarify what is understood by PC. This implies reviewing, albeit briefly, the main conceptual and ideological framework PC is grounded in. Second, we describe the new conceptualisation of disability given by the United Nations Committee on the Rights of Persons with Disabilities, tasked with ensuring compliance with the Convention on the Rights of Persons with Disabilities. In Spain, this Convention is about to give rise to substantial legislative reforms in civil and procedural matters, leading to a turnaround in the way the matter has been traditionally treated. Thirdly, we expose a critique of the demands to turn "functional diversity" into the sole politically correct expression to refer to the condition of people with disabilities. To finish, I come back to the question of PC and present my position on the effects of this doctrine on the prevention of discrimination against marginalised groups.

Reading poetry is one of the language skills, the skills are reading poetry in public with correct pronunciation, beautiful intonation, and correct expression. However, especially students at MI Nurul Huda Sungai Binjai, Keritang District did not read poetry by applying the conditions or rules for reading poetry. For instance: not reading poetry with the correct pronunciation, not using beautiful intonation, also not expressing the poetry properly. Thus, the training was given to students to read poetry properly. The method used in this service is the training method. The result of this training indicated that students able to read poetry with correct pronunciation, beautiful intonation, and they can read poetry with correct expressions.

Battle for the Soul of a City: John Roach Straton, Harry Emerson Fosdick, and the Fundamentalist-Modernist Controversy in New York, 1922–1935

The Fundamentalist-Modernist Controversy was a defining moment for New York in the 1920s and one of the most significant theological battles in the city's history, as key doctrines of the Christian tradition such as the Virgin Birth, the Atonement, and the bodily resurrection of Christ were debated in the mainstream as well as the religious press. The principal figures in the controversy were John Roach Straton and Harry Emerson Fosdick, two prominent clerics whose intellectual and oratorical confrontation showed just how deep this nationwide religious divide had become. Straton and Fosdick used their New York pulpits as public platforms to articulate their opposing theological visions and to justify them as the correct expression of historic Christianity in the present. In doing so, they made the Fundamentalist-Modernist Controversy very much a New York story, remapping the city's Protestant evangelical culture and reorienting one of the most important episodes in American religious history. The aftermath of the conflict, however, reveals that the lines between “fundamentalist” and “modernist” as distinct categories of religious experience became blurred as each embraced elements of the other. By 1935, both fundamentalists and modernists in New York City had been transformed, just as they had transformed the city.

Flow entry conflict detection and resolution scheme for software-defined networking

Software-defined networking (SDN) has the ability to flexibly configure the network and is widely used in various scenarios. In SDN, different applications require the controller to deploy corresponding flow entries to maintain the effectiveness of network. However, the matching field range covered by entries of different applications may overlap, and when actions specified by these overlapping entries are inconsistent, conflicts may occur. Such conflicts may cause the flow to match the wrong entry, thereby affecting the correct expression of application functions. The scheme we proposed in this paper will be able to detect and resolve conflicts between flow entries. Firstly, we discussed the causes of conflicts, and then classified various conflict situations. This classification will help us to adopt different ways of resolving different types of conflicts and make the resolution of conflicts more targeted. Next, we propose a conflict detection algorithm based on B+ tree. This algorithm can detect different types of conflicts. According to theoretical proof, the use of B+ tree compared with other similar structures better in the performance of the time and space complexity. Finally, for the detected conflicting entries, we propose a conflict resolution scheme based on the failure degree of the flow entry according to the characteristics of SDN services tending to be more detailed. Through experimental evaluation, our scheme can effectively detect and resolve conflicts with lower overhead.

LANGUAGE CLICHÉS IN THE METHODOLOGY OF TEACHING RUSSIAN AS A FOREIGN LANGUAGE

The purpose of this study is to determine the role of language clichés in the practice of teaching foreign languages and, in particular, Russian as a foreign language. In the course of the study, the relevant features of language clichés were identified, including those that distinguish them from phraseological units; the classification of language clichés by the functions of language expressions is made; and the methodology for them in relation to a foreign audience is described. In addition, it was found that the use of clichés as the most stable reproducible linguistic terms in a foreign language, helps to avoid errors associated with the wrong lexical collocation, and also contributes to a more correct expression of thoughts for a given language which in turn makes the communication more effective and responsive to the communicative tasks of its participants. In this regard, language clichés should be paid a special attention, both by researchers and teachers, in this case working with foreigners. It should be kept in mind that there might be no such fixed phrases in the language of foreign students, or they can have a different structure, which means that in many times students cannot independently recognize and purposefully memorize such units; that is why all the necessary semantic work with such language clichés should be carried out in class.
