. Heat exchangers are devices that facilitate the heat exchange between two or more fluids that are at different temperatures and apart from one another, and they can have several different forms, including shell-and-tubes, serpentine, fins, plates, concentric tubes, among others. In the present work an experimental investigation of slope influence of thermosyphons applied to cross-flow heat exchangers was performed. To that effect, thermosyphons were manufactured in copper with an outer diameter of 9.45mm, an inner diameter of 7.75mm, and a total length of 180mm, of which 60mm are for the evaporator, 60mm are for the adiabatic section, and 60mm are for the condenser. The thermosyphons were filled with distilled water with 40% of the evaporator volume, tested experimentally at different slopes (0, 22.5, 45, 67.5, and 90° in relation to the horizontal) under power dissipations ranging from 1 to 11W and its cooling being performed by air forced convection. The thermal analysis was based on the temperature distribution along the length, on the operating temperature and on the thermal resistance. In view of the results observed for thermal performance, it was possible to determine that the best working slope was 67.5° in relation to the horizontal, given that it presented lower values of thermal resistance and lower operating temperature.

. Breast cancer is the main cause of death among women, and infrared thermography is one of the techniques capable of assisting its detection. The objective of this work is to compare the thermal contrasts in the skin surface in the thermal recovery, with and without hyperthermia, after a period of hypothermia in a breast, by a thermographic analysis in the COMSOL software and to verify if the thermal recovery by hyperthermia increases the thermal contrast obtained. The methodology was based on Pennes’ equation in a two-dimensional model of an anatomically similar breast, which presented healthy tissue and with tumor. The obtained results indicated that the application of hyperthermia in the breast thermal recovery does not increase significantly its thermal contrast under the conditions of the numerical model, in addition to causing permanent thermal damage to tissue cells if the time or intensity of the heat flow remains unchanged.Therefore, further studies are still needed to improve infrared thermography techniques so that it is possible to identify breast cancer early.

. Acoustic metamaterials are materials that have physical characteristics not found in nature and can be used to obtain sound absorption behaviors, until then, impossible with conventional materials. The objective of this bibliographic review is to systematically select relevant scientific articles that discuss the influence of 3D printing in the production of acoustic metamaterials using the Scopus database. For this purpose, the advanced search tool on the Scopus website was used in order to filter the number of articles to be read, selecting at first look articles related to engineering and materials science. Finally, seventy-six articles were obtained, of which two stood out as the most cited and two others as the most convergent related to the influence of 3D printing in the production of acoustic metamaterials. The recent publication date of these articles between 2014 and 2023 reveals a Chinese dominance in the scientific production on the subject, in addition to the fact that currently it is the period of greatest intensity of study and that new methods of producing metamaterials bring with them a promising future for research in that area.

. This article aims to compare the torque and power curves of the VW EA211 1.0 L 3-cylinder engine in the naturally aspirated (MPI) and turbocharged with direct injection (TSI) versions, obtained through tests aided by eddy current roller dynamometers, both running on Brazilian ethanol as fuel. Based on the 2018 NBR ISO 14396 engine test standard and experimental methodology for exploring the systematic and random errors inherent in the system and the natural variability of the measurand. In view of the results obtained and the comparison of the curves for the engine in its aspirated version with homogeneous injection in the manifold and in the version with turbo compressor and direct fuel injection, it was possible to notice the efficiency gain provided by the overpressure in the admission in the case of the TSI , that the reduction of engines and the use of fuel injection technologies combined with compressors allow better performance to be extracted from smaller engines without neglecting the specific consumption of the engine.
． 本文旨在比较大众EA211 1.0 L 3缸发动机在自然吸气(MPI)和涡轮增压直喷(TSI)版本下的扭矩和功率曲线，这些曲线是通过涡流滚筒测力仪辅助测试获得的，两者都以巴西乙醇为燃料。基于2018年NBR ISO 14396发动机测试标准和实验方法，探索系统固有的系统和随机误差以及测量的自然变异性。根据所获得的结果和曲线的比较，在歧管中均匀喷射的吸气版本和在涡轮压气机和直接燃油喷射的版本中，可以注意到在TSI的情况下，进气道中的超压提供的效率增益。发动机的减少和燃油喷射技术与压缩机相结合的使用，可以在不忽视发动机具体消耗的情况下，从更小的发动机中提取出更好的性能。

. In the last decades, the global industry has been experiencing a technological advance that is providing the development of the concepts of the Fourth Industrial Revolution. In this context, small and medium-sized enterprises (SMEs) need to overcome a series of challenges to implement these emerging technologies, which are currently more within reach of larger companies. One of the challenges perceived by SMEs is choosing the most appropriate technology for them. In this sense, the Analytic Hierarchy Process (AHP) tool proved to have the potential to help decision-making, including helping Brazilian industries to choose technology. In order to contemplate both the wills and the real needs of the companies, data from specialists in the industrial area and data that demonstrate the wills of the companies were collected. This collection took place through prioritization questionnaires with the companies participating in the research. This method proved to be efficient in directing the choice of a technology for consultants and companies. In addition, it was noticed that most of the companies selected for the study had a greater need for the technological use case defined as "Process Monitoring", followed by the use case of "Asset Tracking" and finally, "Digitization of Industrial Processes".
