In light of the increasing environmental challenges and the need for sustainable and circular practices, the adoption of low-carbon technologies (LCTs) is vital. To achieve this transition, it is essential to train a skilled workforce in LCTs aligned with sustainability and circularity principles. This paper investigates the knowledge gaps and discusses emerging trends in this area through bibliometric analysis. This is followed by a systematic roadmap, which aims to facilitate widespread adoption of LCTs through curriculum and faculty development, infrastructure and laboratory investment, industry partnerships and policy engagement. This work contributes valuable insights to the discourse surrounding the broader adoption of LCTs while upholding the principles of sustainability and circularity.

A study of the production of prompt J/ψ mesons contained in jets in proton-proton collisions at s=8TeV is presented. The analysis is based on data corresponding to an integrated luminosity of 19.1 fb−1 collected with the CMS detector at the LHC. For events with at least one observed jet, the angular separation between the J/ψ meson and the jet is used to test whether the J/ψ meson is part of the jet. The analysis shows that most prompt J/ψ mesons having energy above 15 GeV and rapidity |y|<1 are contained in jets with pseudorapidity |ηjet|<1. The differential distributions of the probability to have a J/ψ meson contained in a jet as a function of jet energy for a fixed J/ψ energy fraction are compared to a theoretical model using the fragmenting jet function approach. The data agree best with fragmenting jet function calculations that use a long-distance matrix element parameter set in which prompt J/ψ mesons are predicted to be unpolarized. This technique demonstrates a new way to test predictions for prompt J/ψ production using nonrelativistic quantum chromodynamics. Physics Letters B, 804 ISSN:0370-2693 ISSN:0031-9163 ISSN:1873-2445

Abstract Being widely used, personal computers (PCs) are, in relation to harmonics emission, very important within the category of non-linear low power loads (IL ≤ 16 A). A simultaneous operation of a group of PCs causes the distortion of the current waveform and negatively affects the supply of voltage. Therefore, the exact determination of current harmonics quantified with total harmonic distortion, THDI, is of great importance. The existing models and expressions for the THDI are not adequate in cases of large PC clusters. The aim of this paper is to present an improved analytical expression for the determination of the THDI dependence on the PC cluster size, suitable for practical engineering application. Based on the data available in references, the results of power quality measurements carried out in a computer centre on a group of 163 PCs, and the results of computer simulations, the THDI function on PC cluster size proposed in the paper is simple and easy to implement. The expression is suitable for engineering application for PC clusters up to 200 PCs per phase and for the most probable network connection of the cluster. It allows quick assessment of the current distortion, without the use of a simulation software. To improve the applicability, the influence of the stiffness of the grid is considered separately and then included in the enlarged expression. At the end, the effects of AC/DC power conversion, grid stiffness and cluster size on model application is further discussed. A direction for future research is also given.

Tourism is the most important export sector in Montenegro, with a share of 22% of the total Gross Domestic Product (GDP) and a strong tendency toward growth. Tourism revenues contribute substantially to both the current account balance and employment. However, the current level of the tourist sector suffers from serious limitations. The switch from the current approach to tourism in Montenegro to a more sustainable tourism is only possible by becoming more innovative. Highlighting the importance of innovation in all its forms has been the motivation for our research. The application of the organizational, marketing, and design innovations of the Montenegrin tourism industry actors was examined in a survey, based on the Community Innovation Survey (CIS), with some necessary adaptations. The sample covered more than 70% of available tourism actors. The authors also analysed the experience from Slovenia, in particular the Slovenian example of the Bank of Tourism Potentials, finding this innovation potentially suitable for transfer to Montenegro. Based on the survey and analysis, the team designed certain recommendations for policy action that can be used as guidelines for policy makers.
