The Vite Maritata as a Landscape Catalyst. The Grapevine as Part of Edible Greenways
No full textThe grapevine on living trellises, or “vite maritata” in Italian, is an ancient grape growing technique that uses, instead of poles, trees as support for the grapevine to climb. Conceived by the Etruscans, it was a common element in the Italian rural landscape until the 1960s. As an agronomic practice, it has been abandoned mainly because of the ceasing of the socioeconomic forces that drove its expansion, summarized by sharecropping. Today, in evaluating the natural ecosystem and environment, we have the theory of ecosystem services as a powerful tool. This theory states that ecosystems impact human well-being. This impact affects four different categories that group the various services provided by ecosystems. These four categories are provisioning, regulating, cultural, and supporting. The grapevine on living trellises provides services in all four categories, with precise services regulating microclimate and supporting wildlife (Bigliardi, 2021). The linear arrangement of the grapevine on living trellises in the urban landscape could function as a helpful green infrastructure for wild species of animals and plants, but of course, also for human beings, contrasting territorial fragmentation and promoting biodiversity. As a greenway, it can be a source of recreational spaces and slow mobility and provide substantial food resources, becoming the protagonist of an edible landscape (Fabris, 2010). The Metropolitan City of Milan possesses already a substratum of dismissed railway yards that, united with the renovation of the Navigli canal system, define a favourable environment for the design of this kind of greenways that can contribute to the “ForestaMI” Reforestation Plan of the Lombard metropolis (Boeri, 2021). Moreover, the “vite maritata” fits well with this situation, being acclimated to the climate of the Po valley
Contrast-enhanced ultrasound of the normal canine prostate gland
No full textCanine prostate gland abnormalities affect a large number of adult male dogs. In veterinary medicine, the commonly used methods to diagnose canine prostate gland disease are digital rectal examination and abdominal ultrasound. We evaluated the ability of ultrasound contrast agent to provide additional information about the vascularity of the canine prostate gland; such information could be useful in detecting early prostate gland disease and in staging disease known to be present. We characterized the ultrasonographic appearance of prostate gland vascularity in 10 healthy dogs before and after the injection of an ultrasound contrast agent (Levovist TM). Before injecting Levovist TM, the prostate gland blood flow was classified as poor in all dogs, whereas after contrast agent injection blood flow was classified as moderate or good, in 3 and 7 dogs respectively. Knowledge of the status of prostate gland vascularity could be useful for the characterization, diagnosis and therapeutic monitoring of canine prostate gland lesions
STUDY ON INACTIVATION KINETICS OF HEPATITIS A VIRUS AND ENTEROVIRUS WITH PERACETIC ACID AND CHLORINE. NEW ICC/PCR METHOD TO ASSESS DISINFECTION EFFECTIVENESS
No full textThe virucidal activity of chlorine-compounds was studied using hepatitis A virus (HAV) and Poliovirus 2 and comparing the disinfectant efficiency of peracetic acid. HAV presented a higher resistance to HClO than Poliovirus did.
With ClO2 the inactivation times of HAV were markedly shorter.
A comparison between these data and those resulting from the tive than chlorine.
As a preliminary to future research, the PCR-test integrated with cell-cultures was experimentally introduced for a quick evaluation of the HAV-infectiveness, with the aim of possible application in the field of disinfection and of viruses isolation from environmental and food samples
START UPS AND SPIN-OFFS: THE ROLE OF BUSINESS INCUBATORS
No full textIn this age of exponential technology development and globalisation, innovation and entrepreneurship have become one of the key drivers (if not the key driver) of economic growth (Bathelt and Spiegel, 2011). Within this context, it is well accepted that also Universities can be central to the growth and development, especially if they support start-up and spin-off processes (Bigliardi et al., 2013; Galati et al., 2017). Indeed, the main involvement of universities refer to the creation of spin-offs companies (both based on intellectual property developed at the university or resulted from university–industry joint ventures), and start-ups (Mustar et al., 2006). Academic spin-offs are firms that are created by researchers to commercialize their innovations and research results (Shane, 2004). Similarly, start-ups are newly emerged entrepreneurial ventures aiming at meeting a marketplace need by developing a viable business model (Mustar et al., 2004). Both spin-offs and start-ups may have high failure rate or face difficulties especially in their initial development stage, thus needing a support. Business incubators usually assist these emerging ventures by providing support services and assistance in developing their business (Lalkaka, 2002).
The objective of this study is twofold: as first, to propose a taxonomy of start-ups, spin-offs and business incubators; as second, to define the role of business incubators in supporting emerging ventures. To reach this objective, after a brief introduction on the concept of spin-offs and start-up and their importance for the economic development and innovation, starting from the analysis of the available literature, a business incubator definition is given and all the various types of services offered by the incubator structure to the tenant companies are explained. Finally, we classify start-ups and spin-offs and map business incubators according to factors such as their objectives, mission, activities and role
