One Year Clinical Evaluation of Milled BioHPP Polyetheretherketone (PEEK)-Based versus Metal Ceramic Single Crowns (Randomized Controlled Clinical Trial)
Authors: Badran Abdelrahman , Zaki Amina , Rabie Karim 
Published: July 2021

Objective: To evaluate the clinical behavior of milled BioHPP PEEK copings veneered with Visio.lign composite resin in comparison with metal copings veneered with feldspathic porcelain as single posterior crowns. Material and Methods: Twenty Four full coverage posterior crowns were fabricated for endodontically treated molars divided into 2 groups according to the material used. Twelve milled BioHPP PEEK-based crowns (Group 1) and Twelve Porcelain Fused to Metal (PFM) crowns (Group 2). The preparations were standardized with an equi-gingival, deep chamfer finish line for all teeth. BioHPP PEEK and metal copings were fabricated by CAD/CAM technology and lost wax technique respectively. These coping were veneered according to manufactures instructions either by special composite resin or low fusing glass ceramic respectively. The restorations were cemented then clinical evaluation of these crowns was assessed regarding mechanical failure, marginal integrity and patient satisfaction every two months for one year. Results: Although two PEEK crowns were fractured, both PEEK and PFM crowns showed similar fracture (mechanical failure) and marginal integrity without significant difference (P > 0.05). BioHPP PEEK-based crowns showed statistically significantly lower patient satisfaction than PFM crowns after six months (P-value = 0.013, Effect size = 1.157) but all the patients were generally satisfied. Conclusion: BioHPP PEEK-based crowns showed clinically similar and accepted mechanical behavior and marginal integrity but less patient’s satisfaction than PFM crowns after six months. So BioHPP PEEK-based crowns may be used as an alternative tooth-colored metal-free fixed restoration for one year.

Effect of Thermo-Mechanical Aging and Repressing on Fracture Resistance of Lithium Disilicate Crowns
Authors: El-Etreby Amr , Metwally Mahmoud , EL-Nagar Gihan 
Published: July 2021

Objective: The recycling of heat pressed lithium disilicate glass-ceramic leftover material has been reported to be done by dental laboratories. The effect of this procedure on the fracture resistance of single crowns is unknown, especially when it is functioning inside the oral cavity with subsequent exposure to temperature changes and cycles of mastication. Material and Methods: A total of 28 lithium disilicate glass-ceramic crowns (IPS emax Press) were constructed and randomly assigned into two groups (n = 14); Group (P): Included crowns fabricated from new e.max ingots. Group (R): Included crowns fabricated from repressed e.max buttons. Specimens of each group were divided into two equal subgroups (n = 7) according to whether the aging of specimens will be performed or not before fracture resistance testing. Subgroup (N), samples were subjected to fracture resistance without thermo-mechanical aging, while subgroup (A), samples were subjected to thermo-cycling and cyclic loading before being subjected to fracture strength testing. Different methods; SEM, XRD, EDAX were used to characterize the properties of lithium disilicate glass-ceramics before and after repressing. Results: The highest statistically significant fracture resistance value was recorded for the subgroup (RN) repressed/non-aged, followed by the subgroup repressed/aged (RA), while the lowest statistically significant mean value was recorded for the subgroup pressed/aged (PA). There was no significant difference between pressed/non-aged (PN) and repressed/aged (RA) subgroups. Conclusion: Repressing of leftover buttons may increase the fracture resistance of IPS emax Press crowns. Thermo-mechanical aging may negatively affect the fracture resistance of IPS emax Press crowns, yet Repressing may decrease this effect. Clinical implications: This is a novel approach that targets a point of research that has not been investigated before. It elaborates how repressing may decrease the effect of aging and increase the fracture resistance of lithium disilicate crowns. Thus, recycling of lithium disilicate glass ceramics might decrease its failure and prolong their serviceability.

The purpose of the present study was to evaluate special features and probable correlations between symptoms, laboratory findings, treatment, and outcomes of COVID-19 in children and adolescents, through a systematic review and pooled analysis. Following database (Pubmed, Google Scholar, Scopus and Embase) search, forty articles were considered eligible identifying a total of 2,971 confirmed pediatric COVID-19 patients. Fever was reported in 55.1% of the cases, while 28.4% were asymptomatic. Radiological signs of pneumonia were observed in more than half of the cases and in 40.7% of asymptomatic patients. Fever showed the highest sensitivity (sensitivity: 60.3%, specificity: 48.8%), followed by cough (sensitivity: 47.4%, specificity: 76.7%), rhinorrhea (sensitivity: 21.1%, specificity: 88.4%) and diarrhea (sensitivity: 10.3%, specificity: 88.4%), in differentiating cases with positive radiological signs for pneumonia. Compared to school age children, preschoolers (adjusted OR=6.01, 95%CI: 1.73-20.91) were more prone to pneumonia findings. Various combinations of treatments were used across studies, without following any strict guidelines. Most children (>90%) had full recovery and rarely presented complications. Fever seems to be the most frequent symptom in pediatric COVID-19, but pediatricians should additionally evaluate cough, rhinorrhea, and diarrhea as indicators of SARS-CoV-2 infection. Asymptomatic cases were common, but not the majority, and a significant percentage had developed radiologic findings of pneumonia. Thorough reassessment of treatment and management guidelines should be helpful.

‘Behold, I tell you a mystery’: Tracing Faust’s Influences on Giorgio Agamben to and from International Law
Authors: Bikundo Edwin 
Published: July 2021

Abstract
It is a mystery as to why more is not made of the influence of Johann Wolfgang von Goethe’s Faust on Italian philosopher Giorgio Agamben’s body of work. After all, as a great philosophical poet, and tremendously concerned with language, Goethe’s work could not have failed to capture Agamben’s attention, especially given his early and sustained interest in poetry. Indeed, Agamben cites Goethe in at least 12 of his works including: The Use of Bodies, Creation and Anarchy, Pilate and Jesus, The Kingdom and the Glory, Homo Sacer, The Signature of All Things, Stanzas, The End of the Poem, Potentialities, Karman, Adventure and Infancy and History. Crucially, the last five reference Goethe’s Faust directly. Thus, this paper seeks to remedy the relative lack of explicit engagement and demonstrate the strong, clear and persistent influence of Goethe’s Faust that underpins Agamben’s signature philological and philosophical approach to literarily explicating law’s foundational riddles. Agamben’s Homo Sacer, project – it must be recalled – quite accidentally began in part as a direct response to the legalistic justifications for the 1990–91 Gulf War. The present discussion seeks to demonstrate that Goethean influence ironically enough through a close examination of both Faust’s and Agamben’s attempts at partially translating a biblical phrase: ‘in the beginning was the word’.
Politics of Silence: On Autonomous, Communicative and Aesthetic Silences
Authors: Kaura-aho Katariina 
Published: July 2021

Abstract
The article analyses the political meaning of silence by reflecting on the communicative, autonomous and aesthetic function of silence in context of prevailing political speech systems. In the article, silence is interpreted as an active communication form, as an activist protest tactic and as an aesthetic practice. The article argues that silence can have a politically subversive function toward prevailing aesthetically organised speech systems.Conventionally, silence is devalued in Western societies that primarily celebrate the expressive and communicative capacity of verbal speech. In theorising about radically egalitarian politics, it is however crucial to note the various ways in which silence can be an important source of power. Silence holds the potential for certain active political change in current legal-political frameworks. On the one hand, silence can enable new communication forms and actualise alternative political solidarities and attachments. Also, the logic of oppressive speech systems can be resisted through silent political action. On the other hand, it is in an individual’s own practices of silence, ones that silent protests can bring about in their aftermath, where the sensibility of prevailing political speech orders can be rearranged. The article analyses these many meanings of political silence.
The Role of Clerics in North African Third-Century Martyr Narratives

Abstract
The comparison of the role of the clergy in the Passio Perpetuae, the Vita Cypriani, the Passio Mariani et Iacobi, and the Passio Lucii et Montani reveals that tensions around the respective authorities of clerics and martyrs/confessors continue to divide Christians in Carthage after the death of Cyprian.
Otra forma de ver el paisaje: “paisaje sacro” y topoastronomía en Viveiro (Lugo, España)
Authors: Almagro-Gorbea Martín , Bouzas Sierra Antón , Ladra Lois 
Published: July 2021

Análisis etnoarqueológico interdisciplinar del paisaje sacro del territorio de Viveiro (Lugo) como aproximación empírica para mejorar la metodología existente para interpretar el “paisaje sacro” y aproximarnos a la mentalidad y al imaginario de la sociedad prerromana, una metodología que abre nuevas vías de investigación.
Se analiza las características geográficas y la articulación territorial con el rio Landrove, un hidrónimo celta, como eje. Se ha identificado la desconocida población de *Landobriga, en el Castro da Croa de Landrove, como centro sacro de ese territorio, cuyos habitantes pudieran denominarse *Landi, “Los hombres del llano” y también se señala la posible organización cuatripartita del territorio característica de los celtas. Particular interés ofrece la orientación topo-astronómica de muchos lugares sacros, con leyendas y ritos asociados de origen prerromano. Estos alineamientos topo-astronómicos permitían determinar los equinoccios y solsticios y las festividades celtas de media estación, Imbolc, Beltaine, Lugnasad y Samain, de acuerdo con el calendario ritual y la cosmología celtas, hecho que resalta el significado y la importancia de los análisis topo-astronómicos.
Este análisis evidencia una continuidad de “longue durée” hasta la actualidad de los principales lugares sacros y su gran densidad en el territorio. Esta continuidad y densidad del “paisaje sacro” es característica de la religión gallega, pero procede de los numerosos numina loci celtas, como confirman los Dinshenchas, numina en ocasiones relacionados con creencias animistas.
Los resultados confirman la importancia del “paisaje sacro”, reflejado en tradiciones, ritos, mitos y leyendas populares del folklore, que confirman las alineaciones topoastronomicas. Esta nueva forma de leer el paisaje es una enriquecedora aportación para conocer el imaginario y la religión popular que permite comprender mejor cómo veía el hombre prehistórico su territorio y los elementos que lo conforman como un paisaje vivo y sobrenatural, de carácter sacro, dentro de tradiciones ancestrales de origen animista.

OBJECTIVES
To quantify adolescent- and parent-perceived importance of provider-adolescent discussions about sexual and reproductive health (SRH), describe prevalence of provider confidentiality practices and provider-adolescent discussions about SRH topics during preventive visits, and identify missed opportunities for such conversations.

METHODS
We used data from a national Internet survey of 11- to 17-year-old adolescents and their parents. Data were weighted to represent the noninstitutionalized US adolescent population. Adolescents who had a preventive visit in the past 2 years and their parents reported on perceived importance of provider-adolescent discussions about SRH topics: puberty, safe dating, gender identity, sexual orientation, sexual decision-making, sexually transmitted infections and HIV, methods of birth control, and where to get SRH services. Adolescents and parents reported whether they had ever discussed confidentiality with the adolescent’s provider. Adolescents reported experiences at their most recent preventive visit, including whether a provider spoke about specific SRH topics and whether they had time alone with a provider.

RESULTS
A majority of adolescents and parents deemed provider-adolescent discussions about puberty, sexually transmitted infections and HIV, and birth control as important. However, fewer than one-third of adolescents reported discussions about SRH topics other than puberty at their most recent preventive visit. These discussions were particularly uncommon among younger adolescents. Within age groups, discussions about several topics varied by sex.

CONCLUSIONS
Although most parents and adolescents value provider-adolescent discussions of selected SRH topics, these discussions do not occur routinely during preventive visits. Preventive visits represent a missed opportunity for adolescents to receive screening, education, and guidance related to SRH.
Tasa de fecundidad infantil y la paulatina no declaración de los progenitores en Costa Rica (2000-2019)
Authors: Fuentes Rodríguez Eugenio 
Published: July 2021

Introducción: la maternidad infantil debe evidenciarse por su propia naturalización social como producto de violaciones. Es relevante su estudio luego de aprobadas algunas leyes que buscan evitarla. Objetivo: analizar el comportamiento de la tasa de fecundidad en niñas entre 10 y 14 años en Costa Rica (2000-2019) y la edad de los perpetradores o «padres» en el marco de los aparatos ideológicos de Estado, desigualdad social y dentro de un contexto social conservador. Método: la información se extrajo de las bases de datos en línea del Instituto Nacional de Estadística y Censos. El abordaje es cuantitativo, con un estudio correlacional y no experimental de la población descrita en todo el país y en áreas geográficas pequeñas. Resultados: la fecundidad infantil ha disminuido entre los años 2000 y 2019. La edad estimada de embarazo es cuando se cumplen los 13 años. Se detectaron áreas geográficas con mayores niveles de fecundidad dentro y fuera del Gran Área Metropolitana. Se evidenció estadísticamente que algunas leyes han contribuido al aumento considerable de perpetradores no declarados luego de 2016. Todo esto fue validado por instituciones religiosas y los medios de comunicación lo pregonaron como positivo, a pesar de la jurisprudencia nacional e internacional. Conclusiones: esta información es trascendental para orientar las políticas públicas educativas y de salud desde el primer nivel de atención, con miras a promover los derechos reproductivos de las niñas.
Harmonic Uniformity and Hungarian front/back harmony
Authors: Rebrus Péter , Törkenczy Miklós 
Published: July 2021

AbstractIn the paper we argue against the traditional assumption about the relationship between morphology and harmony in Hungarian according to which monomorphemic and polymorphemic (suffixed) forms behave in the same way harmonically within the domain of harmony. We show that the harmonic properties of the root are inherited by morphologically complex forms based on the root and this can override the phonological restrictions on harmony. We propose an Optimality Theory analysis of the interaction between the phonological constraints on harmony and the paradigm uniformity constraint Harmonic Uniformity.
Underlying representation of [w]-final words in Brazilian Portuguese: Evidence from morphological derivation
Authors: Schwindt Luiz Carlos 
Published: July 2021

AbstractThis paper deals with the underlying representation of [w]-final words in Brazilian Portuguese, usually spelled with <l> and pronounced as [w] and occasionally as [ɫ] (e.g.,papel/ [paˈpɛw] ~ [paˈpɛɫ] ‘paper’). It focuses on non-verbs derived by a vowel-initial suffix preceded by [l] (e.g.,papel+eiro‘paper+suffix’ / [papeˈlejɾʊ] ‘papermaker’;cliente+ismo‘client+suffix’ / [kliẽnteˈlizmʊ] ‘patronage’). The results from a pseudoword task answered by 219 participants contrasted to lexicon data from Corpus Brasileiro show that native speakers associate such derived forms with bases already containing [l] in the last syllable, either in the onset or the coda position. This observation is interpreted in a constraint-based approach, with the assumption that a demand for alignment between vowel-initial suffixes and roots closed by /l/, along with the requirement for phonological correspondence between base and derivative, is highly ranked in a grammar that accounts for learning morphophonological representations in the language.
Broken rotor bars fault detection in induction motors based on current envelope and neural network
Authors: Mustafa Mohammed Obaid 
Published: July 2021

The growing demand for dependable manufacturing techniques has sped up research into condition monitoring and fault diagnosis of critical motor parts. On the other hand, in modern industry, machine maintenance is becoming increasingly necessary. An insufficient maintenance strategy can result in unnecessarily high downtime or accidental machine failure, resulting in significant financial and even human life losses. Downtime and repair costs rise as a result of failure. Furthermore, developing an online condition monitoring method may be one solution to come up for the problem. Early detection of faults is very vital since they grow quickly and can cause further problems to the motor. This paper proposes an effective strategy for the classification of broken rotor bars (BRBs) for induction motors (IMs) that uses a new approach based on Artificial Neural Network (ANN) and stator current envelope. The stator current envelope is extracted using the cubic spline interpolation process. This is based on the idea that the amplitude-modulated motor current signal can be revealed using the motor current envelope. The stator current envelope is used to select seven features, which will be used as input for the neural network. Five IM conditions were experimentally used in this study, including a part of BRB, 1 BRB, 2 BRBs and 3 BRBs. The new feature extraction and selection approach achieves a higher level of accuracy than the conventional method for motor fault classification, according to the experimental results. Indeed, the results are impressive, and it is capable of detecting the exact number of broken rotor bars under full load conditions
