After the recent global financial and economic crises, unemployment, especially among young people have become a particularly serious problem. Fostering young entrepreneurship represent not only a tool to combat young unemployment and social exclusion but also a way to encourage innovation and a country's economic growth. Education and training can contribute in building an entrepreneurial society and may shape individuals attitudes versus risk-taking. Risk taken ability is an important personality factor who have an influence in process decision making or in entrepreneurial intention. Our main objectives are directed towards identifying whether there is a significant relationship between willingness to take risks, entrepreneurship education and students intention towards entrepreneurship. The present study tested two hypotheses on a sample of 115 university students using a questionnaire-based survey. The response scales use anchors such as 5-point Likert scale (1, strongly disagree to 5, strongly agree) and semantic differentials metrics. Tests and modelling were performed using Statistical Package for Social Science (SPSS) software, SPSS 21.0. According to our research objective and developed hypotheses, several data analysis have been used: Principal Component Analysis (PCA) and OLS regression models. Our findings reveal that both Risks taken Ability and Entrepreneurial Education significantly influence the entrepreneurial intentions of Technical University students.

In this mini-review, we describe some of the latest facts regarding the generation of condensed base phonons by biological entities, initially described by the renowned contemporary physicist, Nobel laureate, Herbert Fr?hlich, who proposed a new biophysical interaction mechanism between extremely high frequency electromagnetic waves and the biological environment. As we will show, this extremely low intensity millimeter therapy crystallizes as an important new method, universal and effective in the management of diseases with different etiologies. Moreover, the existence of internal electromagnetic fields generated by biological entities, as well as external electromagnetic fields, are essential for understanding the electromagnetic-biological effect. In fact, it is estimated that at present millimeter-wave therapy is used for the management of more than 120 diseases in cardiology, neurology, oncology, gynecology, urology, gastroenterology, surgery, pharmacology and pediatrics. However, so far there is still no consensus regarding the interaction between extremely high frequency/extremely low intensity electromagnetic waves and the biological environment at its different levels of organization. Thus, the present paper was intended to contribute to the development for the theory of millimeter-wave interaction with living biological entities.

The paper presents some preliminary results on using a new supplementary Cementitious material based on industrial by-products most of them unrecyclable until recently. The opportunity for using such industrial unrecyclable wastes in construction industry has recently been recognized by researchers as having net benefits for the environment. This strategy has the potential to reduce costs, conserve energy and minimize waste. The concept very much fits into the era of sustainable development. In view of this fact, the effect of curing conditions on the self weight and strength characteristics of an eco-mortar is studied and preliminary encouraging results are presented. The eco-cement, in the form of anhydrous calcium sulphate, is set to replace the ordinary Portland cement in the mix proportion. It is made from industrial wastes and can be entirely recycled after its expiration date. The curing conditions consisted in air curing for 28 days or various time intervals for curing in water until the day of testing. The strength properties at the age of 28 days are investigated in terms of bending tensile strength and compressive strength. The obtained results show that the curing conditions play an important role both on the self weight and on the strength characteristics.

Abstract. For the past decades the importance of structural rehabilitation of historical buildings, in order to preserve the cultural heritage, has increased considerably. The weak masonry (made from bricks and bounded with low-strength mortars) were created using mortars which, depending on different external factors, were degraded and there are necessary urgent rehabilitation interventions in order to assure the masonry's durability by protecting the joints with new, compatible and reversible materials and techniques (according to Venice charter requirements). In order to increase the durability characteristics of the weak masonry, the design and application techniques of some particular materials and solutions used will be considered in present paper. The used procedures are based on joints reinforcing using fibre reinforced mortar (fibres made of steel, carbon and glass). The test results have revealed a significant improvement of the structural response and a noticeable increased durability depending on the materials and techniques used.

Creating new construction materials with improved strength, elasticity, and durability properties represent the focus of many research works. Significant research effort has been invested in investigating the use of carbon nanotubes (CNTs) in cementitious materials, especially multi-walled carbon nanotubes (MWCNTs) which consist of a series of concentric graphite tubes. The use of MWCNTs is closely related to the use of surfactants and ultra-sonication procedures which may alter their properties and the properties of cement-based materials. The paper presents the preliminary results of an experimental investigation on the suitability of using a new, modified, MWCNT type aimed at eliminating the need of using surfactants and ultrasonication. The modified MWCNTs have a much lower surface energy compared to “classical” ones which would result in a decreased tendency of self-aggregation. A comparison was carried out from the point of view of density, flexural and compressive strength as well as dynamic modulus of elasticity of the obtained mortars. The mortar mix incorporating the modified MWCNTs showed improved mechanical properties even for a low percentage of CNT addition (0.025% by mass of cement). The results are discussed based on the material structure determined from a series of scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses.

Non-destructive tests to assess the dynamic characteristics of the materials are important for both in-situ and laboratory situations. Elastic modulus, rigidity modulus and Poisson ratio can be determined through dynamic testing, by employing resonant frequency measurements. The ASTM C-215 standard contains the necessary information for the experimental set-up and subsequent computation using the longitudinal, transversal and torsional frequencies, for both prismatic and cylindrical specimens. Nevertheless, some experimental particularities are not explained and their influence on the final results might prove important. In this paper, the experimental and computational insights on performing the dynamic Young modulus test for cement mortar prismatic samples, with emphasis on the importance of interpretation of the results are presented. The type of specimen support and the actual data manipulation, when extracting results, are taken into consideration. The results may prove important for the correct employment of dynamic testing.
