| The concept of pollution prevention, or "P2," signifies a new, proactive environmental mindset that targets the causes, rather than the consequences, of polluting activity. While anecdotal evidence suggests that P2 opportunities exist and that many have been pursued, there is also the perception that the pace of P2 is far too slow. To explore that claim--and to shed light on barriers to P2 innovation--this paper presents case studies of industrial P2 projects that were in some way unsuccessful. While based on a very limited sample, the evidence contradicts the view that firms suffer from organizational weaknesses that make them unable to appreciate the financial benefits of P2 investments. Instead, the projects foundered because of significant unresolved... |

| The purpose of this paper is to determine what factor affect trust in scientists and food manufacturers, and to examine how trust in these institutions affects public support for biotechnology. Data from the U.S. Biotechnology Study reveal that benefits from biotechnology and expectations of trustworthiness are correlated with trust in scientists, but benefits and costs of biotechnology, and expectations of trustworthiness and competence of biotechnology institutions, are important determinants of trust in food manufacturers. The data also reveal that trust in scientists and food manufacturers has a large and important effect on public support for biotechnology, but trust in scientists is more important for public support than trust in food manufacturers. |

| Why do biotech firms cluster? New and established firms in biotech clusters are said to capitalize on knowledge spillovers, labor-market pooling, and other externalities. Some have even argued that such spillovers are so strong that the cluster itself, rather than the individual, is the locus of entrepreneurship. Such arguments, however, do not resolve the mechanism by which clusters might contribute to the establishment of new firms. This paper proposes a conceptual framework for analyzing the locational choices of entrepreneurial firms in the life-sciences industry. Building on both the cluster literature and the literature on entrepreneurship, we develop hypotheses about how cluster characteristics, the entrepreneurs personal characteristics, and... |

| In Europe the demand of functional foods varies remarkably from country to country, on the basis of the alimentary traditions, the enforced legislation and the different cultural heritage that people have acquired. The opportunities of expansion on the market seem to be quite favorable and the interest of the consumers is rather high. But the diffusion of these products in the community area is slowed down by some obstacles. One of main ones is the lack of an official law-recognized definition for these references, necessary in order to clearly assign these products to the food sector rather than to the pharmaceutical one. In a such situation, we note that nowadays it is impossible to carry out a complete survey of this world, due to the lack of... |

| The paper examines effects of different inorganic salts in an apple pulp base on the production of pectinolytic enzymes with the aim of optimizing the medium for maximal enzyme production. The apple pulp combined with corn flour and simple mineral salts was used as a nourishing base in submerged production of pectinolytic enzymes by the fungus Aspergillus niger MK-15. The growth of the microorganism (dry weight) on different sources of nitrogen showed maximum dry weight with (NH4)2HPO4. The growth of the microorganism (dry weight) on different concentration of (NH4)2HPO4 (by 0.2% to 0.8%) provided maximal dry weight with 0.7% (NH4)2HPO4. The different inorganic salts (sources of nitrogen) on base stimulated the production of pectinolytic enzymes and... |

| For the purpose of acquiring a highly active producer of pectolytic enzymes, there was a probe of isolating 140 species of Aspergillus’s fungi from different substrates (soils, grape malts, grapes, apples and sugar beet shreds). The isolated kinds of fungi were kept on a slant agar surface according to Chapek, with 2% of pectin. Testing was performed on the isolated layers of fungi as to the production of pectinolytic enzymes. The nourishing base used was the synthetic Chapek base with 2% pectin, 2% lactose and 0.7 % (NH4)2HPO4, and a natural base of 1% refuse apple pulp. Within 48 hours after cultivating the fungi, the filtrates were tested by the viscozimetric method to determine their entire pectolytic activity. The acquired results showed that a... |
