Introduction: The number of Tattoo artists has been increasing and there are important Occupational Risks associated. The aim of this article was to describe the position of these professionals regarding the Recommendations and to analyze their compliance when working alone or accompanied. methodology: It is a mixed Exploratory Study, involving a quantitative component (Observational Analytical of transversal nature), operated through an online survey and, in a second phase, a qualitative one (Case Study), through the use of interviews. A representative sample of the population under study was obtained, considering a 90% confidence interval. The research project was approved by a Ethics Committee and informed consent was obtained. Presentation and Discussion of the Results: The sample considered 207 questionnaires and nine interviews. The compliance with Standards increases with experience;those who reported that they do not always comply are those who use less the Personal Protective Equipment (t = 2.659;p = 0.008). Compliance is also influenced by the Perception of Risk, information, social pressure (more accentuated by COVID19) and motivation to increase profit. Those who considered the Recommendations to be adequate were statistically associated with compliance with Collective Protection measures. Regarding the compliance when working alone or not, 86.0% stated that they maintained the same posture;of those who answered the opposite, 85.7% complied more alone. Those with less education were statistically associated to less compliance with the rules when alone (X2 = 12.763;p = 0.005). Final Considerations: Previously unpublished data has been obtained, valuable to act effectively in this professional sector. It is fundamental to invest in training, as well as to elaborate Standards (developed jointly by Doctors/Safety Technicians and Tattoo artists). The organization of the Conventions should guarantee adequate conditions (area, access to disinfection/

Spouting behavior of binary particle mixtures of different densities: Fluid dynamics and particle segregation

引用

Particuology 2019年第1期17卷 58-66页

Numerous industrial applications of spouted beds involve a mixture of granular particles, where differences in particle size, density, and shape can cause particle segregation, affecting the quality of flow and decreasing product homogeneity. The aim of this study was to investigate the particle segregation and fluid dynamics of a conical spouted bed operating with a binary mixture of particles of different densities. Using glass beads and polyethylene particles with a diameter of 4 mm, we determined the effects of the mass fraction of denser particles and static bed height on the minimum spouting condition and mixture index. The pressure drop and airflow in the minimum spouting condition increased with an increase in bed height or jetsam concentration. Regarding particle segregation, the jetsam particles tended to concentrate near the bottom, at the spout–annulus interface because they have a shorter trajectory than the lighter particles in the fountain region. Jetsam-rich mixtures with high initial static bed heights exhibited more efficient particle mixing, excluding those at the bottom of the bed.

Protection measures and Change in the Perception of Work Risks with COVID-19, in a Representative Sample of Portuguese Tattoo Artists

引用

Occupational Diseases and Environmental medicine 2023年第1期11卷 49-65页

作者： mónica santos Faculdade de Engenharia da Universidade do Porto Porto Portugal

Introduction: Tattoo Artists are exposed to Occupational Hazards, but the bibliography is scarce. methodology: this is a mixed Exploratory Study carried out with a quantitative component (online questionnaire) and a qualitative component (online interview). The questionnaire was available between April 2020 and march 2021 and was distributed by the companies/professionals that work on Tattoos, main national magazines in the sector, companies that supply products and equipment and organizing committees of the main national congresses. The research project was approved by the Ethics Committee of the Faculty of Arts of the University of Porto (28.04.2020) and an informed consent was obtained. As an inclusion criterion, it was considered to carry out tattooing tasks on a paid basis. As exclusion criteria, working outside the country or not mastering the Portuguese language stood out. Results: 207 Tattoo Artists answered the questionnaire (25.87% of professionals registered in Portugal) and nine interviews took place. Numerous statistically significant associations were found between the variables analysed. Final considerations: the main weaknesses of the study are related to the difficulties inherent in data collection: as it was carried out using an online questionnaire, it was not controlled whether all respondents practiced the profession of Tattoo Artists. Furthermore, as it is a voluntary questionnaire, it is possible that the sample retained professionals who value Occupational Health issues. This investigation combined quantitative and qualitative techniques, so that it was possible to take advantage of and mitigate the disadvantages of both;in fact, the qualitative aspect sequentially completed and explored the data initially obtained in the survey, as well as it allowed to deepen issues initially not programmed, such as the possible interference of the Pandemic associated with SARS-COV2 in the general Risk Perception and compliance with the Standards of Good Pr

Nanostrain measurement Using Chirped Bragg Grating Fabry-Perot Interferometer

引用

Photonic Sensors 2012年第1期2卷 77-80页

作者： Ricardo m. SILVA marta S. FERREIRA Jose L. santos Orlando FRAZAO INESC Porto Rua do Campo Alegre 687 4169-007 Porto Portugal and Faculty of Sciences of University of Porto Rua do Campo Alegre 687 4169-007 Porto Portugal

A simple nanostrain direct current （DC） measurement system based on a chirped Bragg grating Fabry-Perot （FP） structure is presented. The FP cavity, formed between the chirped fiber Bragg grating （CFBG） and the fiber end face, presents an aperiodic behavior due to the CFBG. A laser located in the fringe pattern slope is used to interrogate the sensing head. The optical power parameter is analyzed when strain is applied, for long and short period fringe pattern wavelengths, and sensitivities of-2.87 μW/με and-5.48μW/με are respectively obtained. This configuration presents a resolution of 70 ε.

选取32头混合品种羔羊,分成4组,日粮中分别包含榆钱、蒺藜纤毛、南洋樱和木薯,试验结束后评估其肉品质和感官品质。饲喂榆钱组羔羊肉品质蒸煮损失显著减小(P0.05)。然而,青贮饲料的不同对羊肉的香味、肉色和风味有显著影响(P<0.05)。木薯组和南洋樱组羊肉风味更好。榆钱组羊肉的风味较佳,蒺藜纤毛组风味较差。日粮中添加蒺藜纤毛降低产肉量。基于胴体重和肉品质的差异,饲料中添加榆钱和木薯可提高肥育绵羊生产性能。
