Analysis of Warning Threshold of Tunnel Monitoring and Measurement Based on Probability Statistics

In the process of tunnel construction, data on deformation monitoring magnifies the direct reflection of the stability of tunnel structure, and the setting of early warning value is more related to the safety of project construction. In this paper, a tunnel project is taken as an example, and based on a large number of previous engineering practices and the statistical characteristics of monitoring data, the probability statistics method is used to obtain the warning threshold, which is used to give suggestions for the construction of the tunnel project and provide technical reference for the monitoring and warning management of similar tunnel construction.

Assessment and Monitoring of Carbon Monoxide (CO) Concentrations in High Traffic Areas (HTA) of Maiduguri Metropolitan of Borno State, Nigeria

The research investigated the carbon monoxide concentrations in heavy traffic areas of Maiduguri metropolitan between three weeks has been performed. Maiduguri City is located at latitudes 11 42N and 12 00 N and longitudes 12.54 and 13 14 E and has a land area of 543 km2 in the Northern-Eastern region of Nigeria. The high concentration of Carbon monoxide (CO) pollutants in high traffics area of Post office of Maiduguri city. The high traffic area (HTA) was selected for the research and the concentration of Carbon monoxide was monitored and measured, monitoring and measurement were planned daily between 8:00 a.m. to 8:00 p.m. for three weeks. The average result obtained was the highest point of 36 ppm and lowest point of 12 ppm in the three weeks, the highest point is above both WHO and FEPA points of 25 ppm and 30 ppm, respectively.

Periodontal Surgery for Correction of Gingival Smile: a Case Report Analysis of Periodontal Parameters after 2 Years

Gingival smile is a term used to describe an aesthetic condition in which excessive gingival exposure at the jaw level occurs during smile. There are several factors related to its etiology, the most common is the altered passive eruption of anterior superior teeth. To correct this disharmony, a multidisciplinary approach is necessary, and the treatment plan depends on a correct diagnosis and assessment for a better prognosis. The present study aims to describe a clinical case where periodontal surgical techniques were used to correct this condition. Female patient, 25 years old, with aesthetic complaint of the amount of gum exposed when smiling and diagnosed with altered passive eruption. Clinical crown augmentation surgery was performed on the anterior superior teeth. After 1 and 2 years, periodontal clinical parameters (probing bleeding, probing depth, clinical attachment level, crown length, keratinized mucosa width and plaque index) were reassessed, through clinical examination, digital photographic monitoring and measurement tools. In two years, it was possible to note the stability of the results achieved, maintaining values similar to those of the immediate postoperative period. The case report confirmed the success of the clinical crown augmentation surgery and the periodontal parameters stability evaluated after 2 years. Keywords: Periodontics Surgery. Gingivectomy. Aesthetics. ResumoSorriso gengival é o termo utilizado para descrever uma condição estética em que ocorre uma exposição gengival excessiva ao nível da maxila, durante o sorriso. Há diversos fatores relacionados a sua etiologia, sendo a mais comum a erupção passiva alterada dos dentes ântero-superiores. Para correção dessa desarmonia é necessária uma abordagem multidisciplinar, sendo o plano de tratamento dependente de um correto diagnóstico e avaliação para um melhor prognóstico. O presente estudo tem objetivo de descrever um caso clínico onde técnicas cirúrgicas periodontais foram utilizadas para correção dessa condição. Paciente gênero feminino, 25 anos de idade, com queixa estética da quantidade de gengiva exposta ao sorrir e com diagnóstico de erupção passiva alterada. Foi submetida a cirurgia de aumento de coroa clínica nos dentes antero-superiores. Após 1 e 2 anos foram reavaliados os parâmetros clínicos periodontais (sangramento a sondagem, profundidade de sondagem, perda de inserção, comprimento da coroa, largura da mucosa queratinizada e índice de placa), através de exame clinico, acompanhamento digital fotográfico e ferramentas de medição de imagem. Em dois anos, foi possível constatar a estabilidade dos resultados alcançados, mantendo valores semelhantes aos do pós-operatório imediato. O relato de caso confirmou o sucesso da cirurgia de aumento de coroa clínica e a estabilidade dos parâmetros periodontais avaliados após 2 anos. Palavras-chave: Periodontia. Cirurgia. Gengivectomia.

HARDWARE AND SOFTWARE COMPLEX FOR MEASURING HARD X-RAY RADIATION ON THE TORSATRON “URAGAN-2M”

This paper presents an automated measuring system for radiation monitoring and measurement of hard X-ray radiation in real time on the "Uragan-2M" torsatron. The system includes an ionizing radiation detector based on a scintillator and a photomultiplier tube, equipment for preliminary processing and normalization of detector signals, and a microcontroller unit for control, measurement and processing.

Opportunities for digitalization of quality management systems

In the context of digitalization, the functioning of the QMS necessitates the development and application of qualitatively new management technologies, as well as fundamentally new production technologies. Science is faced with the question of studying the main ways of developing the QMS, determining its place and role in modern conditions and realities, including the use of digital technologies. The article defines the sections of the QMS (GOST R ISO 9001-2015), in which digital technologies can and should be implemented: clause 8.3 Design and development of products and services, clause 8.4. Production of products and provision of services, p. 7.1.5 Resources for monitoring and measurement, p. 9.3. Management analysis.

Propuesta de una herramienta para el seguimiento y medición en instituciones de educación Proposal for a tool for monitoring and measurement in educational institutions

Esta investigación presentó la propuesta de una herramienta para el seguimiento y medición en las instituciones de educación, teniendo como referentes los criterios del European Modelo of Business Excellence (EFQM) y los requisitos de la Norma Técnica Colombiana ISO 9001:2015, con el fin de establecer los indicadores mínimos que debería tener en cuenta cualquier entidad educativa para facilitar el seguimiento de la gestión, la toma de decisiones y proporcionar una base para la obtención de un reconocimiento de calidad. La investigación se desarrolló en tres fases; en la primera, se identificaron los aspectos comunes en cuanto a seguimiento y medición del modelo de excelencia EFQM y la Norma Técnica Colombiana ISO 9001:2015, obteniendo los criterios que dieron paso a la segunda fase, en donde se construyó el modelo de seguimiento y medición, compuesto por los indicadores y el cuadro de control; y en la tercera fase se realizó la validación del modelo mediante la consulta a expertos, en donde se identificó la viabilidad del modelo para su aplicación.
