Moral norms and the forgotten virtue of Epikeia in the pastoral care of the divorced and remarried

The virtue of epikeia is relevant for many issues that arise in contemporary society, including pastoral concerns in our parish communities, among which, a particularly diffcult one is the pastoral care of the divorced and remarried. is article will include two parts. First, I will focus on how the understanding of epikeia developed historically in order to present its various nuances systematically. I will clarify the different nuances of the understanding of this virtue in three key authors representative of the tradition. Second, I will raise a number of questions for the further examination of the issue of the pastoral care of the divorced and remarried.peer-reviewe

Predicting Engine Parameters with Cost Efficient AI Models – An Experimental Method Validation

Artificial intelligence (AI) methods have rapidly become a best practice in various industrial applications due to their exceptional predictive abilities. Compared to traditional physical and chemical models, AI-driven approaches typically offer faster computation times without sacrificing accuracy. This makes them well-suited for enhancing or replacing conventional methods in engine technology. Building on this potential, our previous work focused on developing AI-based tools to accelerate the development of novel e-fuels for internal combustion engines. These AI tools require representative training datasets created through expensive engine dyno measurements. To address this challenge, we developed a general methodology to improve the cost-efficiency of dataset creation. This paper presents the experimental validation of this methodology by assessing its performance on seven different predictive tasks. Following the proposed framework, we designed and conducted an engine dyno experiment, then developed AI models to predict seven critical engine performance and emissions parameters: center of heat release, ignition delay, peak combustion temperature, peak pressure rise rate, brake thermal efficiency, exhaust opacity and NOx emissions. The results demonstrated the effectiveness of the methodology, with five out of seven models achieving excellent predictive performance on unseen test data (R2 > 0.97). Peak pressure rise rate and opacity models had slightly lower performance (R2 > 0.94), however, given the well-known challenges associated with predicting these parameters, the results are acceptable

Effects of Oxymethylene Ether in a Commercial Diesel Engine

Oxymethylen Ether (OME) is a promising alternative fuel for diesel engines. It can be produced sustainably, and its combustion is clean and efficient. This study investigates the effects of different OME$_{3-5}$ mixtures on emissions and combustion. The measurements were done on a four-cylinder common rail commercial diesel engine equipped with an exhaust gas recirculation system (EGR). Five different blends of OME$_{3-5}$ and B7 diesel were applied with 0, 7, 15, 25 and 45 vol% OME$_{3-5}$content at four loads. The NO$_{x}$–PM trade-off was investigated at 11 EGR rates for each mixture at each load. Increasing OME$_{3-5}$ mixing ratio reduced the PM emission, improved the NO$_{x}$–PM trade-off, and increased the brake thermal efficiency. The maximum achieved PM emission reduction was 86.8% for high loads. However, NO$_{x}$ emission increased, and also low heat capacity and viscosity can be a problem for real applications

Prepare for being old as long as there is still time

The content of the paper concerns the reflection on the responsibility for aging from the individual-ethical point of view, as well as party from the socio-ethical one. In the empirical aspect, there will be presented the science currently particularly important for getting old, namely genetics. In terms of anthropology some values of aging will be considered for human dignity, freedom and historicity. Single ethical realizations concern generations contract, learning how to shape time especially social time a central task of a family, erotica and sexuality in old age, integration of their own life story and biblical interpretation of these tasks

Folyékony hajtóanyagok fejlesztési tendenciái

A 21. század egyik kihívása a mobilitás felé az energiaellátás biztosítása. A középpontba kerülő környezetterhelés, a vírus miatti logisztikai nehézségek és az Európában zajló háború új kihívás, már-már sokk elé állították a mobilitás energiaellátását. Cikkünkben alágazatonként áttekintjük, hogy a terjedő elektromobilitás mellett miért van szükség a folyékony hajtóanyagokra. Bemutatjuk az alternatív hajtóanyag fejlesztéseket első-, másodgenerációs és fejlett hajtóanyagok területén
