From Capitulations to Unequal Treaties: The Matter of an Extraterritorial Jurisdiction in the Ottoman Empire

In the nineteenth century, justice in the Ottoman Empire appeared to international jurists deeply corrupted and far from the Western model. European consular jurisdictions, as in the past, solved this embarrassment in the prevalent and private interest of Western States in order to control the Mediterranean area. This perpetrated abjuration to recognize an autonomous and sovereign Ottoman administration of justice in civil or criminal cases in which foreigners were involved continued, in spite of the fact that the Porte provided excellent examples of intersection, reception and appropriation of foreign models to construct a new legal system, and to transform society. This process of “westernization” or “modernization” formally started in 1839, by the Hatt Hümayün of Gülkhâne. In order to halt the contradictions derived from the coexistence of the last (French and English) treaties of commerce of 1838 and their confirmation of privileges and consular jurisdiction with the driven effort of Ottoman juridical reforms of Tanzîmât period, in 1840 in both Turkey and Egypt, mixed traders councils composed of local and foreign traders were established. In 1840 the “commercial board” was born in Turkey and, in 1848, European Powers holding capitulary privileges negotiated the formal recognition of mixed tribunals (which were regulated in 1873 and formally inaugurated in 1875). This embarrassing situation was getting worse and accumulating contradictions when in 1856, at the Congress of Paris, the Ottoman Empire was “admitted to participate in the advantages of European Public Law and system” (art. 7 of the Treaty). Thanks to those words, the logical preamble of consular jurisdictions and their extraterritoriality (mitigated by the “monstrous” compromise of mixed tribunals), formally failed. There was a need to investigate and redefine the paradigmatic declensions of sovereignty in the relations between European Powers and the Ottoman Empire during the nineteenth century

Endodontic retreatment of a lower canine associated with a periapical lesion: case report of an unusual anatomy

Abstract Objectives To describe the endodontic orthograde retreatment of a lower canine with a rare anatomy, affected by a symptomatic periapical lesion. Materials and methods A 30-year-old Caucasian woman came to our office reporting severe pain and swelling located at the right mandible. A two-roots/two-canals configuration was discovered for the lower canine which sustained the periapical infection; a missed lingual canal was not recognized and treated at the previous primary endodontic therapy. A full pre-operative examination and diagnosis, the application of modern endodontic strategies along with the use of magnification technologies (like the Surgical Operating Microscope - SOM) and proper disinfection protocols were employed for endodontic re-treatment. Result and conclusions Healing of the periapical infection was clinically and radiographically confirmed at a 9-month follow-up. Endodontists should know the anatomical variations of human teeth and be vigilant about them when approaching treatments. More than a single radiographic projection is recommended in the diagnostic phase. Careful procedures related to instrumentation, cleaning and filling of the entire root canal system enhance the potential for healing of apical lesions

Security Management Framework for the Internet of Things

The increase in the design and development of wireless communication technologies offers multiple opportunities for the management and control of cyber-physical systems with connections between smart and autonomous devices, which provide the delivery of simplified data through the use of cloud computing. Given this relationship with the Internet of Things (IoT), it established the concept of pervasive computing that allows any object to communicate with services, sensors, people, and objects without human intervention. However, the rapid growth of connectivity with smart applications through autonomous systems connected to the internet has allowed the exposure of numerous vulnerabilities in IoT systems by malicious users. This dissertation developed a novel ontology-based cybersecurity framework to improve security in IoT systems using an ontological analysis to adapt appropriate security services addressed to threats. The composition of this proposal explores two approaches: (1) design time, which offers a dynamic method to build security services through the application of a methodology directed to models considering existing business processes; and (2) execution time, which involves monitoring the IoT environment, classifying vulnerabilities and threats, and acting in the environment, ensuring the correct adaptation of existing services. The validation approach was used to demonstrate the feasibility of implementing the proposed cybersecurity framework. It implies the evaluation of the ontology to offer a qualitative evaluation based on the analysis of several criteria and also a proof of concept implemented and tested using specific industrial scenarios. This dissertation has been verified by adopting a methodology that follows the acceptance in the research community through technical validation in the application of the concept in an industrial setting.O aumento no projeto e desenvolvimento de tecnologias de comunicação sem fio oferece múltiplas oportunidades para a gestão e controle de sistemas ciber-físicos com conexões entre dispositivos inteligentes e autônomos, os quais proporcionam a entrega de dados simplificados através do uso da computação em nuvem. Diante dessa relação com a Internet das Coisas (IoT) estabeleceu-se o conceito de computação pervasiva que permite que qualquer objeto possa comunicar com os serviços, sensores, pessoas e objetos sem intervenção humana. Entretanto, o rápido crescimento da conectividade com as aplicações inteligentes através de sistemas autônomos conectados com a internet permitiu a exposição de inúmeras vulnerabilidades dos sistemas IoT para usuários maliciosos. Esta dissertação desenvolveu um novo framework de cibersegurança baseada em ontologia para melhorar a segurança em sistemas IoT usando uma análise ontológica para a adaptação de serviços de segurança apropriados endereçados para as ameaças. A composição dessa proposta explora duas abordagens: (1) tempo de projeto, o qual oferece um método dinâmico para construir serviços de segurança através da aplicação de uma metodologia dirigida a modelos, considerando processos empresariais existentes; e (2) tempo de execução, o qual envolve o monitoramento do ambiente IoT, a classificação de vulnerabilidades e ameaças, e a atuação no ambiente garantindo a correta adaptação dos serviços existentes. Duas abordagens de validação foram utilizadas para demonstrar a viabilidade da implementação do framework de cibersegurança proposto. Isto implica na avaliação da ontologia para oferecer uma avaliação qualitativa baseada na análise de diversos critérios e também uma prova de conceito implementada e testada usando cenários específicos. Esta dissertação foi validada adotando uma metodologia que segue a validação na comunidade científica através da validação técnica na aplicação do nosso conceito em um cenário industrial

Effect of different dental articulating papers on SEMG activity during maximum clenching

This study evaluated the influence of two different occlusal indicators (articulating papers of 40\u3bcm and 200\u3bcm) on muscular activity of the temporalis anterior (TA) and superficial masseter (MS) during maximum voluntary clenches (MVC), using surface electromyography (SEMG). It was hypothesized that an articulating paper positioned between dental arches during MVC elicits a different muscular activity compared with the occlusion on natural dentition (without the occlusal indicator). 30 healthy adult subjects with a complete, natural dentition were recruited; SEMG activity was recorded in the following experimental conditions: MVC with cotton rolls for standardization purposes; MVC on natural dentition; MVC onto the 40 \u3bcm or 200\u3bcm paper indicator positioned on right or left side of the dental arch. Percentage Overlapping Coefficient (POC; separate values obtained for TA and MS), antero-posterior coefficient (APC) and total muscle activities (IMP) were the analyzed SEMG parameters. The use of an occlusal indicator statistically changed POC_TA, POC_MS and IMP median values (p 0.05). In conclusion, the examined articulating papers affected two specific SEMG parameters (POC and IMP); the recorded muscular activity with the occlusal indicator varied regardless left or right side positioning, and independently from tested paper thicknesses
