On their way towards assuring growth and long-term sustainability, many modern small and medium sized enterprises (SMEs) from the European Union have set building a stronger brand as one of their primary goals. To achieve this, an integrated framework for managing the continuous enhancement of their brand equity level by adopting digital marketing tools and techniques (DMTTs), has increasingly become a necessity for most of the modern SMEs. However, even if such an approach provides plenty of benefits, such as better audience targeting and reduction of traditional marketing expenses, implementing these complex processes in their business models poses a series of challenges like choosing the best selection of DMTTs. For this reason, a conceptual model is proposed in the first part of the paper, with the aim to highlight a framework that will help underline the links between DMTTs and other key elements that can provide an increase in brand equity of SMEs, thus contributing to growth and enhancing the sustainability level. Following the proposed model, research aimed at two main directions has been conducted in the second part. The first direction was to analyze the degree in which modern SMEs from the European Union located in Romania dedicate themselves toward embracing sustainability goals and principles. The second one represents an analysis using also the SPSS software solution on the most used selections of DMTTs mentioned in the presented conceptual model. The results obtained provide a starting point for those modern SMEs that choose to follow the path of sustainability by creating and enhancing their brand equity through DMTTs.

Concrete of various type have been used extensively for the adequate shielding of the radiological equipment using X and gamma rays. In its basic form, concrete is composed of pieces of inert aggregate held together by hardened cement paste. Dierent concrete types with special cements have been prepared. The linear attenuation coecients of conventional concrete and concrete with supplementary mineral additives (barite and witherite) at dierent gamma energies (Co-60: 1.25 MeV, Cs-137: 0.662 MeV, Ir-192: 0.37 MeV) in narrow beam conditions have been measured. This paper includes some experimental data regarding the inuence of barite and witherite additives on photon attenuation coecients of concrete.

Abstract. The purpose of this study was to examining the factors that lead to cloud computing adoption in a higher education setting. This cross-sectional empirical research is based on the Technology Acceptance Model (TAM) framework. Data was collected by surveying 96 students from University Politehnica of Bucharest, Romania. The factors that affect cloud computing adoption in higher education were identified and tested using LISREL software. The findings suggested that factors identified can be successfully integrated in our conceptual model. Perceived value and usefulness have a strong positive influence on intentions to use cloud computing in higher education, but student's attitude towards technology had no significant effects on dependent variable. Perceived risk has significant negative effects on students' intentions to use cloud computing. The findings are expected to enhance the understanding of cloud computing adoption for students and faculty members. The implication of these findings for faculty members and students are discussed.

The purpose of this study is to explore the moderating role of work experience on the relationships between entrepreneurial education, self-efficacy and students’ entrepreneurial intentions. Quantitative data were collected via a questionnaire based by investigating whether engineering students have sufficient entrepreneurial skills to evaluate opportunity, developing new products, and recognizing potential market applications. Engineering students need to be able to exploit opportunities that rely on scientific and technical knowledge to create and capture value by launch new venture. Our important findings have a series of important practical implications for managers, engineering students, engineers, and academic staff interested in encouraging economic growth. The results show that entrepreneurial education and self-efficacy have a positive impact on students’ entrepreneurial intentions. Work experience only has a partial influence on students’ entrepreneurial intentions, it exerts a significant indirect effect does not have a significant moderating effect. The findings of the study also provide practical implications suggest that increasing engineering students understanding and awareness of entrepreneurship lead to greater levels of interest in entrepreneurship careers. To the knowledge of the authors, this study is the first to investigate the mediating effect of work experience on students’ entrepreneurial intentions.
