    The International Maritime Organization (IMO) has implemented rules aiming to halve emissions by 2050 within the maritime industry. Greenport is a port initiative emphasizing environmental sustainability, striving for minimal emissions across all operations and activities. The integration of electric tugboats into maritime operations has garnered significant attention as the maritime industry seeks to address environmental concerns and transition towards sustainable practices. This paper explores the multifaceted advantages and disadvantages associated with the adoption of electric propulsion technology in tugboats. One of the primary advantages of electric tugboats lies in their potential to significantly reduce emissions and environmental impact compared to conventional diesel-powered vessels. By utilizing electric propulsion systems, tugboats can operate with zero emissions at the point of use, thereby mitigating air and water pollution in port areas and surrounding communities. This environmental benefit aligns with global efforts to combat climate change and improve air quality, making electric tugboats an attractive option for ports and shipping companies aiming to reduce their carbon footprint. The adoption of electric tugboats also presents several challenges and considerations. One of the primary challenges is the upfront cost associated with purchasing electric tugboats and establishing the necessary charging infrastructure. While electric tugboats may offer long-term cost savings through reduced fuel and maintenance expenses, the initial investment required for electric propulsion systems and charging infrastructure can be substantial, posing a barrier to adoption for some operators. The adoption of electric tugboats presents both opportunities and challenges for the maritime industry. While electric propulsion technology offers significant environmental and operational benefits, stakeholders must carefully evaluate the advantages and disadvantages to make informed decisions regarding the integration of electric tugboats into their fleets. By addressing challenges such as upfront costs, infrastructure requirements, and technological limitations, the maritime industry can harness the potential of electric propulsion technology to drive sustainable innovation and achieve long-term environmental and economic goals.

    The skull is a bony cavity that protects the brain. The skull is composed of four types of bones, namely, the cranial bones, facial bones, ear ossicles and hyoid bone, but two parts are more important: the skull and the mandible. In humans, these two parts are the neurocranium (brain shell) and viscerocranium (facial skeleton), which includes the mandible as its largest bone. The human cranium, the part that contains the brain, is globular and relatively large in comparison with the face. In most other animals the facial portion of the skull, including the upper teeth and the nose, is larger than the cranium. In humans the skull is supported by the highest vertebra, called the atlas, permitting nodding motion. In this paper we present the influence of neurosurgical procedures and materials to treat skull defects.

    The concept of global order has been a recurring theme of analysis and debate in academia and civil society. This paper proposes a comparative analysis of the contributions of two reference writers regarding the concept of global order. By approaching the works of Henry Kissinger and Immanuel Wallerstein, the authors investigate how Kissinger and Wallerstein perceive and conceive the dynamics and evolution of global order. The research methodology is based on the comparative analysis of the writings of Kissinger and Wallerstein, with an emphasis on theories of realism and their implications for national security and the nation-state. Through this comparative approach, the authors of the article propose to highlight the convergences between the two viewpoints, allowing for a broader understanding of the perspective on the concept of global order. This article aims not only to retrospectively analyse the thinking of Kissinger and Wallerstein but also to formulate some perspectives on the imperious ability of the global order. Thus, the authors of the article may provide an answer to key concerns regarding the viability and sustainability of the current global order, the exploration of reforms, and adaptation to new global realities. This approach contributes to the academic debate and aids the formulation of relevant conclusions concerning possible developments and necessary adjustments within the existent global order.

    In today’s society, mental health is a topic frequently discussed. With the extent of changes in our daily lives in recent years, driven by factors such as the COVID-19 pandemic, the increasing integration of technology into our daily routines, and social pressures, attention to the mental well-being of every individual in society has grown. While some sceptics view it as a topic that is given more attention than it deserves, we must acknowledge the impact that this highly subjective factor has both on every individual within the community we live in and on society as a whole. Mental health has a profound effect on the development of personal life, but it also clearly influences individual performance in academic and professional settings. The well-being of each person and of society, in general, is closely linked to thriving mental health; however, this topic remains stigmatized and often insufficiently addressed.

    The first goal of this study is to examine the performance of a semi-empirical model used for calculating specific energy consumption (SEC) in reverse osmosis desalination. We have introduced a simulation tool (SECSM) to compare this semi-empirical model (SECSEM) and the SECSM. It's worth noting that the simulation model is open source and can be easily integrated easily with other software tools. For this comparison, we explored a temperature range T (10°C - 22°C - 35°C), recovery rate R from 30% to 65%, and a pump efficiency range of γ_HPP ~78% to 98%. An increase in these parameters leads to a decrease in SEC (both SECSEM and SECSM) for systems without energy recovery devices (ERD). However, the introduction of an ERD results in a variable change in SECSEM. Under specific conditions of 35°C, a pump efficiency of 98%, and an R of 65%, the SECSEM reaches its minimum values. In the case of the two-stage unit (TS), the SECSEM and SECSM models converge to the same value of 0.28 KWh/m³. Meanwhile, for the single-stage unit (SS), the values are 0.4 KWh/m³ and 0.39 KWh/m³, respectively. Regarding the unit equipped with the BW 400 34 and SW HF 085 31 membranes, in both SS and TS configurations, the energy consumption for both models converge towards the values 0.71 KWh/m³, 0.70 KWh/m³, and 0.95 KWh/m³, 0.94 KWh/m³ respectively. In the second part of this paper, a comparative study to validate this semi-empirical model without ERD against experimental data was conducted. The SECSEM showed values very close to the experimental results. The findings are discussed below.

    The present study refers to the maximization of self-consumption through the automation of a residential consumer that is or not fed from the low-voltage electrical network and from its own photovoltaic system. The level of self-consumption from photovoltaic sources in the residential sector is strictly dependent on the power installed in the own sources, as well as the load profile of the respective consumer. Two major directions are relevant regarding the possibility of increasing and optimizing self-consumption: the management of electrical energy storage systems (especially through the use of battery systems), respectively the implementation of load management systems, through the partial or total redistribution of their operation over time, but also through prioritization of critical consumers.

    In the present study, the physico-chemical quality of the water in the Midia coastal area, the Tasaul Lake and the Siutghiol Lake water bodies were analyzed, as integrated sites in the territory of the North Dobrogea FLAG. This study allows establishing the state of favourability of the aquatic ecosystem, focusing on the chlorophyll content as the basis of the trophic level. The premise of a stable ecosystem induces the possibility of developing natural fish resources. An essential attribute in the context of preserving natural heritage and increasing the attractiveness for fishing activities, is the need to evaluate the qualitative and quantitative profile of the phytoplankton and, respectively, the eutrophication indicators. If aquaculture activities will be developed in the analyzed areas in the future, they could increase the economic value of the Romanian sector of the Black Sea. The biological analyzes of the water quality are the basis of the substantiation of some methods of its determination and evaluation. Thus, testing the concentration of chlorophyll, the classes of algae and the photosynthetic activity, are useful for the evaluation of eutrophication in the aquatic environment, but also for the evaluation of productivity in the surface waters studied. At the same time, the determination and evaluation of the physical and chemical parameters of water quality allowed the realization of some correlations with the structure of the biota. In this sense, the analysis methods are based on the use of modern equipment based on real time (in situ) determinations.

    In various fields such as Oceanography, interpolation methods are pivotal in generating continuous surface data from discrete point data. This research endeavors to conduct a comprehensive comparison and evaluation of deterministic interpolation techniques, including Radial Basis Function (RBF), Inverse Distance Weighting (IDW), and geostatistical methods like Kriging Universal (KU) and Kriging Ordinary (KO), in the context of mapping sea surface temperature (SST) within the Alboran Sea. Among these methods, the KO interpolation method emerges as particularly promising, boasting a Root Mean Square Error (RMSE) of 0.035 and an impressive coefficient of determination (R²) approaching unity (0.999). Furthermore, the cross-validation results reveal that the KO method not only provides the most accurate estimates but exhibits minimal bias, as evidenced by a mean error close to zero. These findings not only contribute to the field of SST mapping but also have broader implications for the interpolation of other climate parameters.

    Modern technologies require the development of new materials with exceptional properties. Machine Learning (ML) and Deep Learning (DL) techniques have become important tools for discovering new materials and predicting the properties of specific materials, such as glasses. In this paper, we used ML and DL techniques to predict the Young's modulus E of Calcium-Alumino-Silicate (CAS) glasses based on their chemical composition. We evaluated four different algorithms, including Polynomial Regression (PR), Random Forest (RF), K-Nearest Neighbors (KNN), and Multi-Layer Perceptron Regressor (MLPRegressor). We found that the PR algorithm provides excellent predictions without Cross-Validation (CV), while the MLPRegressor yields the best performance when CV is implemented.
