Introduction/Objectives: As Tattoo is being more accepted, more professionals dedicate to it. A study was designed with the aim of analysing the perception of Tattoo Artists regarding their Occupational Health/Safety team (opinion about the support provided);as to find out what type accidents, symptoms and occupational diseases they have, in order to provide a better service. methods: This is a mixed exploratory study, containing a quantitative observational (analytical, cross-sectional) and a qualitative component (Case Study). For the statistical analysis, predominantly non-parametric tests were used. The project was approved by the Ethics Committee and informed consent was obtained. Results: In terms of symptomatology/illnesses, musculoskeletal pathology is the most reported. In terms of accidents, cuts stand out. Several statistically significant relationships were found between the variables analysed. Discussion/Conclusions: The Occupational Health and Security services are considered insufficient by most of the Tattoo artists. It would be desirable that the Occupational Doctor has concrete knowledge regarding Tattooing, in particular semiology/pathology;makes recommendations in pharmacology and/or indicates which exams could be useful. In relation to the Safety Technician, it would be desirable also to have specific knowledge about the sector, making plausible suggestions for improvement.

The thermal nanofluids have garnered widespread attention for their use in multiple thermal systems, including heating processes, sustainable energy, and nuclear reactions. Research on nanofluids has revealed that the thermal efficiencies of such materials are adversely affected by various thermal features. The purpose of the current work is to demonstrate the thermal analysis of Jeffrey nanofluids with the suspension of microorganisms in the presence of variable thermal sources. The variable effects of thermal conductivity, Brownian diffusivity, and motile density are utilized. The investigated model also reveals the contributions of radiation phenomena and chemical reactions. A porous, saturated, moving surface with a suction phenomenon promotes flow. The modeling of the problem is based on the implementation of the Cattaneo-Christov *** convective thermal constraints are used to promote the heat transfer features. A simplified form of the governing model is treated with the assistance of a shooting technique. The physical effects of different parameters for the problem are presented. The current problem justifies its applications in heat transfer, coating processes, heat exchangers, cooling systems in microelectronics, solar systems, chemical processes, etc.

In this study,we investigate the complex relationship between western disturbances(WDs),the El Ni?o–Southern Oscillation(ENSO),and extreme precipitation events(EPEs) in the western Himalaya(WH) during the extended winter season(November–march).WDs west of WH coincide with 97% of recorded EPEs,contributing substantially(32% in winter,11% annually) to total precipitation within *** are 6% less frequent and 4% more intense during El Ni?o than La Ni?a to the west of *** El Ni?o(compared to La Ni?a) years,WDs co-occurring with EPEs are significantly more intense and associated with 17% higher moisture transport over “WH box”(the selected region where most of the winter precipitation over WH occurs).This results in twice the EPE frequency during El Ni?o periods than La Ni?a periods.A substantial southward shift(~180 km) of the subtropical jet(STJ) axis during El Ni?o brings WD tracks further south towards their primary moisture sources,especially the Arabian *** have shown that WDs that are both more intense and pass to the south of their typical latitudes have higher levels of vertically integrated moisture flux(VImF)within *** convergence in the most intense pentile of WDs is 5.7 times higher than in the weakest,and is 3.4 times higher in the second lowest latitude pentile than in the ***,this study demonstrates a direct link between changes in the latitudinal position and intensity of WDs associated with the winter STJ,and moisture convergence,which leads to the occurrence of EPEs over WH during ENSO phases.

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/

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
