Halloysite nanotubes sandwiched between chitosan layers: novel bionanocomposites with multilayer structures
2018
This work is a contribution to the design of multilayer biocomposites based on halloysite nanotubes (HNTs) and chitosan. Both the polymer and nanotubular inorganic additive have been selected among easily available green materials. An innovative preparation procedure based on the sequential casting of chitosan and HNTs has been proposed in order to obtain multilayer composite biofilms. A physico-chemical investigation (contact angle measurements, differential scanning calorimetry, thermogravimetry) has been conducted to characterize the bionanocomposites. As evidenced by scanning electron microscopy, the nanocomposites possess an intermediate halloysite layer between the chitosan ones. The …
Composition of essential oil of lemon thyme (Thymus × citriodorus) at different hydrodistillation times.
2018
Distillation time can both to optimise the production and to engineer the composition of essential oil in essential oil bearing plants. Purpose of this study was to evaluate the effect of duration of hydrodistillation on composition of essential oil of Thymus × citriodorus, the natural source of commercially important geraniol and citral, a component with valuable biological properties. Essential oils were isolated by hydrodistillation at different distillation times and analysed by GC/MS analytical methods. Increase in percentage of essential oil during all hydrodistillation time gradient was uneven. Elongation of hydrodistillation time decreased percentages of monoterpenes but increased p…
French firms’ strategies for protecting their intellectual property
2012
In attempting to protect their innovations, firms can choose from a range of mechanisms, which may be either non-statutory (trade secrets, design complexity, and lead-time advantage over competitors) or statutory (patent, design registration, trademark, copyright). Yet, little is known about how firms do actually make their choices from among these different appropriability mechanisms. The aim of this paper is to determine how French firms’ use of intellectual property protection mechanisms relates to the type of innovation, the characteristics of the market sector in which they operate, the firms’ characteristics, and their human resources strategies. Our empirical model draws on four Fren…
The demand for IPR services - to use or not to use a professional representative
2021
We analysed the use of professional representative services and related outcomes in patent, utility model, design right and trademark filings. We found that: 1) there is a positive association between the use of a professional representative and the likelihood of grant or registration; 2) the demand for professional intellectual property rights (IPR) services is heterogeneous between IPR types: applicants are most likely to hire professional representatives (IPR agents and attorneys) for patents, followed by utility models, design rights and trademarks; 3) individual applicants are less likely to use professional representatives compared to firm applicants. peerReviewed
IPR gender gaps: a first look at utility model, design right and trademark filings
2018
This study extends the analysis of the gender gap in patenting into design rights, utility model (UMs) and trademarks (TMs), which are complementary methods for protecting intellectual property. The analysis is descriptive and uses register data from the Finnish patent and registration office covering the years 1982–2013. A persistent gender gap is found for all intellectual property rights. The gap has narrowed over time for national patent, design right and TM filings but not for UM filings. It is found that, in comparison to men, women are relatively less often single inventors or designers and more often members of inventor or designer teams. peerReviewed
Coumarins and Related Compounds from the Medicinal Plants of Africa
2013
Coumarins (1-benzopyran-2-one) are chemical compounds in the benzopyrone class of organic compounds found in many plants. Coumarins possess a variety of biological properties, including antimicrobial, antiviral, antiinflammatory, antidiabetic, antioxidant, and enzyme inhibitory activity. This chapter gives an overview of the isolation, structural features, and pharmacological actions of variety of coumarins produced by the African plants. The biosynthetic pathway of coumarins is also discussed in this chapter. We identify 117 coumarins in African plants, of which 48 are new. The pharmacological activities of 54 of these coumarins are reported and documented in this chapter.
Il traffico di beni culturali: un caso studio delle distorsioni e dei limiti nel contrasto ai traffici illeciti
2021
La normativa penale italiana di contrasto al traffico di beni culturali presenta ad oggi diversi profili di criticità, a fronte del prosperare del fenomeno delittuoso e dell’indiscutibile rilievo costituzionale del bene protetto. La revisione della disciplina, per quanto necessaria, non può però assumere i contenuti della proposta di riforma attualmente pendente in Senato. Infatti, questa, come accade nel caso degli altri commerci illegali, risente eccessivamente dell’influenza della normativa in tema di organizzazioni criminali, presentandosi come una mera appendice della stessa. L’A. in questo contributo, dopo aver ricostruito la disciplina penale di riferimento, evidenzia piuttosto l’esi…
Institutional Arrangements Matter for Both Efficiency and Distribution: Contributions and Challenges of the New Institutional Economics
2011
Are scholars in the New Institutional Economics tradition systematically disregarding distributive aspects when approaching policy issues as was the case during the 1970s and 1980s? Do economic and political agents usually care about distribution too? To provide an answer to these questions is the basic purpose of this chapter. The analysis carried out demonstrates that not all NIE oriented scholars disregard distributive issues. Some contributions are examined as examples, mainly in the so-called political economy branch of NIE. By means of a well-known graphical tool, the chapter also emphasizes that all of us clearly care about distribution, not just about efficiency, when participating …
Drivers influencing the governance of inter-firm relationships in the biopharmaceutical industry: an empirical survey in the Italian context
2013
This paper focuses on factors influencing the choice of the governance form in inter-firm relationships (IFRs) between pharmaceutical and biotechnology companies. By reviewing the relevant literature on transaction cost economics, property right theory, real option and resources-based view, we located some drivers that might influence such relationships and we formulated a set of hypotheses linking them to governance forms. Such a theoretical framework has been empirically tested through a survey conducted among the Italian companies associated to Farmindustria. Empirical results provide some interesting insights on how shaping bio-pharmaceutical deals; we found that the developmental stage…
How the purpose of the inter-firm relationships influences the choice of the governance form: evidence from the machine tool and the pharmaceutical i…
2013
In today's competitive landscape, the choice of the appropriate mode to govern an inter-firm relationship is a critical factor for companies. In the literature several theoretical strands have examined the impact of the purpose of inter-firm relationships on the forms of governance. Building on a robust literature review on the topic, this study focuses on a specific issue influencing the choice of the form of governance in inter-firm relationships, i.e. the purpose of inter-firm relationships with relation to partner's resources. We gather in a unique framework three typologies of partner's resources, i.e. production, R&D and marketing, and through two empirical analyses in two different I…
