Financing Small Businesses: From Venture Capital to Crowdfunding
2017
Abstract Startups and small businesses are facing many challenges in terms of financing their activities. These types of companies do not have the possibility to access capital market or to make IPO or to borrow money from banks like big, mature or well-known companies (who were at their beginnings startups or small businesses). They have to find different sources for financing their ideas/products/services that are in many cases very risky, hazardous or to ambitious. But, fortunately, the financing alternative for these companies have evolved during the last post crisis years. They have possibility to find some investors that are willing to invest in a non-name company by accessing crowdfu…
A Study on Entrepreneurship at the University of Valencia
2016
In the last few decades, there has been growing interest in the so-called third mission of universities, one of which, the question of entrepreneurship, will be highlighted in this paper. Hence, universities have been configured as institutions to proactively motivate there alumnae, and there, students will find an ideal environment in which to familiarize themselves with the skills and expertise that entrepreneurs require. Furthermore, universities provide advisory services as well as technical support, which are essential elements of sowing the seed of business start-ups. This chapter sets out, from a qualitative perspective, the policies, strategies and actions undertaken by the Universi…
Women entrepreneurship in small service firms: motivations, barriers and performance
2012
This article presents an exploratory study on the characteristics of women entrepreneurs and the businesses they run in the Valencia region. Following a close look at the evolution of literature on women entrepreneurs, the study shows how different internal and external factors affect the motivation, obstacles and performance of firms created by women. These results contribute towards a better understanding of business creation by women as they provide an empirical contrast of these variables (motivation, barriers and performance). Purpose: The purpose of this paper is to examine the characteristics of women entrepreneurs and the businesses they run in the Valencia Region of Spain, in order…
Factors affecting the performance of entrepreneurial service firms
2008
In the current climate, the importance of the role played by entrepreneurship as a palpable reality that enables economic growth at a macroeconomic level, and as a factor that favours the progress of companies at a microeconomic level, has made it the subject of continual analyses from many different perspectives and in a variety of contexts by researchers from around the world. In this study, Spanish entrepreneurial firms in the service sector are analysed in order to determine the factors that influence their performance.
Collaborations between universities and the business environment in Romania
2021
Building closer relationships between universities and companies can encourage exchange of information between the two institutions, to create long-term partnerships and opportunities and stimulates innovation, creativity and entrepreneurship. The main objective of this research is to identify the significant elements of the collaboration between the university environment and the business environment in Romania, by extracting current information about this collaboration and to try to realise a general framework related to this issue. The research is part of a future larger investigation conducted as an integral part of the Erasmus + project Personalized Engineering Education in South Afric…
Reverse electrodialysis performed at pilot plant scale: Evaluation of redox processes and simultaneous generation of electric energy and treatment of…
2017
Abstract This paper describes the experimental campaign carried out with a reverse electrodialysis (RED) demonstration plant (Marsala, Italy) with the main aims of: (i) evaluating the effect of various operating parameters, including the redox processes, on the system performances; (ii) using the plant for the simultaneous generation of electric energy and treatment of wastewater. The prototype (44 × 44 cm2, 500 cell pairs) was tested using both real (brackish water and brine) and artificial solutions. Tests with two different electrode rinse solutions (with or without iron redox couples) were performed. In agreement with the data obtained in the laboratory, the presence of iron ions contri…
Insight into the role of the zeolitization process in enhancing the adsorption performance of kaolinite/diatomite geopolymer for effective retention …
2021
Abstract Diatomite/kaolinite-based geopolymer (GP) was synthesized and incorporated in zeolitization process (Z/GP) to investigate the role of the zeolite phases in inducing its retention capacity of the dissolved Sr (II) ions in water. The retention of Sr (II) ions using Z/GP in comparison with GP was evaluated based on both batch and fixed-bed column studies. In the batch study, the zeolitized geopolymer (Z/GP) shows enhancement in the Sr (II) retention capacity (193.7 mg/g) as compared to the normal geopolymer (102 mg/g). Moreover, the recyclability studies demonstrate higher stability for Z/GP than GP with a retention percentage higher than 90% for five reusing runs. The kinetic and the…
Integrated urban water modelling with uncertainty analysis
2006
In the last twenty years, the scientific world has paid particular care towards the problems that involve the environment. Accordingly, several researches were developed to describe phenomena that take place during both wet and dry periods and to increase the knowledge in this field. In particular, attention was addressed towards the problems linked with receiving water body pollution because of the impact of rain water in the urban environment. In order to obtain a good description of the problem, it is important to analyse both quantity and quality aspects connected with all the transformation phases that characterise the urban water cycle. Today, according to this point, integrated model…
Desulfurization: Critical step towards enhanced selenium removal from industrial effluents
2017
Abstract Selenium (Se) removal from synthetic solutions and from real Flue Gas Desulfurization (FGD) wastewater generated by a coal-fired power plant was studied for the first time using a commercial iron oxide impregnated strong base anion exchange resin, Purolite ® FerrIX A33E. In synthetic solutions, the resin showed high affinity for selenate and selenite, while sulfate exhibited a strong competition for both oxyanions. The FGD wastewater investigated is a complex system that contains Se (∼1200 μg L −1 ), SO 4 2− (∼1.1 g L −1 ), Cl − (∼9.5 g L −1 ), and Ca 2+ (∼5 g L −1 ), alongside a broad spectrum of toxic trace metals including Cd, Cr, Hg, Ni, and Zn. The resin performed poorly again…
Heterogeneous catalytic degradation of phenolic substrates: catalysts activity
2009
This review article explored the catalytic degradation of phenol and some phenols derivates by means of advanced oxidation processes (AOPs). Among them, only the heterogeneous catalyzed processes based on catalytic wet peroxide oxidation. catalytic ozonation and catalytic wet oxidation were reviewed. Also selected recent examples about heterogeneous photocatalytic AOPs; will be presented. In details, the present review contains: (i) data concerning catalytic wet peroxide oxidation of phenolic compounds over metal-exchanged zeolites, hydrotalcites, metal-exchanged clays and resins. (ii) Use of cobalt-based catalysts, hydrotalcite-like compounds, active carbons in the catalytic ozonation proc…
