Nowadays, mitigating climate-altering emissions resulting from air conditioning and mechanical ventilation of indoor spaces is of utmost importance. Encourage the adoption of renewable energy sources for power generation is a critical approach in this regard. Among the available technologies, photovoltaic technology stands as the most mature option. However, it does have limitations, such as reduced efficiency and performance degradation at elevated temperatures. To enhance the efficiency of photovoltaic systems, various solutions have been proposed over time, with significant research focusing on the exploration of new materials. One of the most promising solutions involves panel cooling through the utilization of external fluids, either in a forced or natural manner. Furthermore, the extracted heat from this cooling process can be effectively reused in other industrial processes, adding to its appeal. Nonetheless, despite its potential, the application of panel cooling technology is relatively recent, and assessing its suitability in specific scenarios at an early stage can be challenging. Currently, there is a lack of clear and straightforward methodologies to evaluate the performance gains achievable through the implementation of panel cooling. The primary objective of this research is to present an innovative methodology that can effectively assess panel cooling efficiency on an average daily-monthly basis. Specifically, we propose corrective parameters that modify the widely used Siegel method, which determines the monthly average daily efficiency of uncooled panels. Throughout the study, it has become evident that the input values derived from the UNI standard do not fully represent the real-world conditions. This finding may indicate the necessity for regulatory updates to accurately account for the practical operational environment.
如今，减少室内空间的空调和机械通风所产生的改变气候的排放至关重要。鼓励采用可再生能源发电是这方面的一个重要方法。在现有技术中，光伏技术是最成熟的选择。不过，它也有局限性，如效率降低和高温下性能下降。为了提高光伏系统的效率，人们提出了各种解决方案，其中重要的研究重点是探索新材料。最有前途的解决方案之一是利用外部流体（强制或自然方式）对面板进行冷却。此外，从冷却过程中提取的热量可以有效地重新用于其他工业流程，这也增加了它的吸引力。然而，尽管面板冷却技术潜力巨大，但其应用却相对较晚，在早期阶段评估其在特定场景中的适用性可能具有挑战性。目前，还缺乏清晰、直接的方法来评估通过实施板式冷却技术可实现的性能提升。本研究的主要目的是提出一种创新方法，可有效评估面板冷却的日均效率。具体来说，我们提出了修正参数，以修改广泛使用的西格尔方法，该方法可确定未冷却面板的月平均日效率。在整个研究过程中，我们发现根据 UNI 标准得出的输入值并不能完全代表实际情况。这一发现可能表明，有必要进行法规更新，以准确反映实际运行环境。

Clove oil is an essential oil that has recently been used not only as a health or aromatherapy ingredient but is also widely used as an additive in fuel, especially for compression ignition engines. Essential oils are extracted through distillation from various parts of the clove tree, such as flowers, tree bark, leaves, and even fruit. This study aims to evaluate the combustion performance of a spark-ignition engine fueled by gasoline and essential oil at a concentration of 5-20 % as a blend. This type of research has not been conducted by many researchers, making it difficult to find scientific references related to this type of research. Experiments carried out on a research engine with engine speed variations of 1400–1800 rpm and a constant load of 3 kg. The results show that increasing the essential oil content increases the fuel energy and indicative power, thereby increasing the thermal efficiency. However, the brake power will decrease because most of it is lost owing to heat transfer and friction; therefore, the mechanical efficiency decreases if the percentage of essential oil in gasoline increases. Meanwhile, increased essential oils will reduce CO2 emissions, but HC and CO emissions will increase, especially at high engine speeds.
丁香油是一种精油，近来不仅被用作保健或芳香疗法成分，还被广泛用作燃料添加剂，尤其是用于压燃式发动机。精油是从丁香树的不同部位（如花、树皮、叶子甚至果实）通过蒸馏提取的。本研究旨在评估火花点火发动机的燃烧性能，其燃料为浓度为 5-20% 的汽油和精油混合物。目前还没有很多研究人员进行过此类研究，因此很难找到与此类研究相关的科学参考文献。在一台研究型发动机上进行了实验，发动机转速变化为 1400-1800 转/分钟，负载为 3 公斤。结果表明，增加精油含量可提高燃料能量和指示功率，从而提高热效率。然而，制动功率会下降，因为大部分制动功率会因热传导和摩擦而损失；因此，如果汽油中的精油比例增加，机械效率就会下降。同时，增加精油会减少 CO2 排放，但 HC 和 CO 排放会增加，尤其是在发动机高速运转时。

The dew point temperature can be generated by saturating air with water vapor through several methods, one of which is by creating small-sized air bubbles passed through water in an enclosed space known as a saturator. In practical terms, the dew point temperature produced by this system can be determined by measuring it using a dew point meter. However, the prediction of the dew point temperature generated through theoretical approaches has not been presented before. Thus, in this study, a simulation has been conducted to determine the dew point temperature. The result is then compared to the experimental data. The experiment follows the single pressure humidity generator principle, where a saturator containing a bubble aerator is immersed in a stirred liquid bath. The bath temperature is set to 25 °C, and the gas flow rate is adjusted from 0.1 lpm to 0.4 lpm. The dew point temperature is measured using a 373 LHX chilled mirror dew point meter. On the other hand, the simulation is performed using the Monte Carlo method, and the physical model involves a heat balance between convection and the change in bubble energy. The convection heat transfer coefficient is determined by the behavior of bubble dynamics, which is related to the bubble size and bubble velocity. The dew point temperature obtained from the simulation is assumed to be the same as the bubble temperature. As a result, the simulation data align well with the experimental data.

The design of scaffolds for multi-tissue regeneration is very complex in terms of material and structure, as a direct consequence of hierarchical and organizational features. TRIZ represents the Russian acronym for the “Theory of Inventive Problem Solving” (TIPS). TRIZ is able to identify and codify such principles, using them to make the creative process more predictable. It is a methodology for the identification of the system conflicts and contradictions in order to solve the inventive problems. Its multidisciplinary features and the general approach to product design can make TRIZ as an intriguing starting point for the biomimetic approach in a systematic and organized way. Biomimetics aims at a complete integration between nature and technology. In this scenario, BioTRIZ shares the contradiction resolution method of the Altshuller’s theory, representing a systematic biomimetic approach towards the product design. In the current study, BioTRIZ was considered to systematize the process of bio-inspired design of 3D optimized scaffolds for the regeneration of complex tissue defects. A device for the regeneration of osteochondral tissue defects was considered as a case study. The technical solutions involved the design of a two-compartment, hybrid and functionally graded scaffold.

In this paper, the dynamic behavior of an airless wheel made by additive manufacturing is investigated. A lattice geometry is chosen as the cyclic pattern from which the wheel is built. Initially, a linear numerical model is used to preliminarily assess resonance frequency and mode shapes of the wheel. Afterwards, specimens were tested twice, in August 2020 and after six months, highlighting a relevant frequency and damping shift in the vibrational response. To better understand the reason behind the change over time in the wheel dynamic behavior, dedicated structural dynamics tests at varying temperature and humidity set points were performed in an environmental chamber, consisting in measuring the wheel vibrational response when subjected to temperature and humidity variation.

Creative design methods should allow the extraction of novel wisdoms and favour their integration into many technological domains, thus leading to an innovative product. The current research reports some technical considerations on the role of generative design as a “collaborative partner” in supporting the ideation process through the development of design alternatives in agreement with the designer’s criteria. A specific case study was considered and the role of the generative design method was stressed, also focusing on technical features and differences in terms of solutions for the given design problem. The possibility of selecting well defined manufacturing methods (e.g., traditional or advanced – additive manufacturing) was highlighted.

Data from the Kering Group's 2018 Environmental Profit and Loss (EP&L) statement were examined for their capacity to meet the demand for meaningful and manageable sustainability metrics. Significant resources were invested in creating the data reported in this EP&L statement, as Kering's operations in 104 countries were evaluated in ways separable into almost 1,500 different indicators. The data system was not, however, designed as a measurement system. That is, it was not set up as specifically positing the possibility of estimating separable parameters for comparing company location performances across sustainability challenges. Of particular importance is the lack of information in the EP&L on the overall consistency of the data reported, on the uncertainties associated with the metrics given, and on the meaningfulness of comparisons across environmental impacts, processes, and materials. The results reported here showing far from perfect data consistency and large uncertainties comprise an effort at constructing meaningful measurements that offers important lessons for the redesign of the data and reporting system.
