An insight into the electrical energy demand of friction stir welding processes: the role of process parameters, material and machine tool architectu…
2018
The manufacturing sector accounts for a high share of global electrical energy consumption and CO 2 emissions, and therefore, the environmental impact of production processes is being more and more investigated. An analysis of power and energy consumption in friction stir welding processes can contribute to the characterization of the process from a new point of view and also provide useful information about the environmental impact of the process. An in-depth analysis of electrical energy demand of friction stir welding is here proposed. Different machine tool architectures, including an industrial dedicated machine, have been used to weld aluminum and steel sheets under different process …
Antitumor effect of oncolytic virus and paclitaxel encapsulated in extracellular vesicles for lung cancer treatment
2018
Standard of care for cancer is commonly a combination of surgery with radiotherapy or chemoradiotherapy. However, in some advanced cancer patients this approach might still remaininefficient and may cause many side effects, including severe complications and even death. Oncolytic viruses exhibit different anti-cancer mechanisms compared with conventional therapies, allowing the possibility for improved effect in cancer therapy. Chemotherapeutics combined with oncolytic viruses exhibit stronger cytotoxic responses and oncolysis. Here, we have investigated the systemic delivery of the oncolytic adenovirus and paclitaxel encapsulated in extracellular vesicles (EV) formulation that, in vitro, s…
Development of novel functional ingredients: Need for testing systems and solutions with Caenorhabditis elegans
2016
Abstract Background Nutrition is increasingly understood as a means of maintaining health and well-being and the market for functional foods keeps growing in double-digits. Functional nutrition is seen by many as the interphase between food and pharmaceuticals. In fact, players from both sides are increasingly making moves in the form of strategic alliances, M&A operations and co-investments which are bringing the two realms closer together. Food regulations to prove safety of novel ingredients or to support health claims are every day more stringent and the general public is also increasingly informed about the science, risks and benefits of what they eat. All this presents a magnificent o…
Production performance and economic traits of silkworms (Bombyx mori L., 1758) fed with mulberry tree leaves (Morus alba, var. Ichinose) significantl…
2019
Abstract Production performance of silkworm (Bombyx mori L., 1758) play a pivotal role in sericulture industry and good quality cocoon represents the economic driver of farms. Silkworms are monophagus insects and differences between cocoon characteristics may depend both on mulberry tree leaves quality as well as on genetic selection of hybrid lines. While a huge work was carried out to identify the best feeding sources to optimize yields, genetic types of silkworms with desirable production and economic traits were studied to a limited extent to date. This experimental feeding trial was carried out using a commercial variety of mulberry tree leaves (Morus alba var. Ichinose) to feed a tota…
The Italian law on body donation: A position paper of the Italian College of Anatomists
2021
In Italy, recent legislation (Law No. 10/2020) has tuned regulations concerning the donation of one's postmortem body and tissues for study, training, and scientific research purposes. This study discusses several specific issues to optimise the applicability and effectiveness of such an important, novel regulatory setting. Some of these unsolved issues may involve the grantees of teaching and training activities, the role of academic anatomical institutes, the role of family members in the donation process, the universal time limit indicated for any donation, the handling of corpses, and the limited body donation and its subordination to the donation of organs and tissues. Critical issues …
Place-based innovation in industrial districts: the long-term evolution of the iMID effect in Spain (1991–2014)
2019
ABSTRACTThe innovation-Marshallian industrial district (iMID) effect defines the existence of dynamic efficiency in the Marshallian industrial district (MID) in the form of a positive innovative di...
Performance Study of Twisted Darrieus Hydrokinetic Turbine With Novel Blade Design
2021
Abstract Twisted Darrieus water turbine is receiving growing attention for small-scale hydropower generation. Accordingly, the need for raised water energy conversion incentivizes researchers to focus on the blade shape optimization of twisted Darrieus turbine. In view of this, experimental analysis has been performed to appraise the efficiency of a spiral Darrieus water rotor in the present work. To better the performance parameters of the studied water rotor with twisted blades, three novel blade shapes, namely U-shaped blade, V-shaped blade, and W-shaped blade, have been numerically tested using a computational fluid dynamics three-dimensional numerical model. The maximum power coefficie…
Deliberation favours social efficiency by making people disregard their relative shares: evidence from USA and India
2017
Groups make decisions on both the production and the distribution of resources. These decisions typically involve a tension between increasing the total level of group resources (i.e. social efficiency) and distributing these resources among group members (i.e. individuals' relative shares). This is the case because the redistribution process may destroy part of the resources, thus resulting in socially inefficient allocations. Here we apply a dual-process approach to understand the cognitive underpinnings of this fundamental tension. We conducted a set of experiments to examine the extent to which different allocation decisions respond to intuition or deliberation. In a newly developed app…

Métabolisme sucre-citrate chez Leuconostoc mesenteroides
2001
Sugar citrate cometabolism in Leuconostoc mesenteroides. Bacteria from the genus Leuconostocplay roles in the dairy industry. The most important functions of this bacteria are their ability to produce CO 2 and flavour compounds through lactose heterofermentation and citrate uti- lization. Although the biotechnological role of the citrate metabolism is very important and widely appreciated, little is known about the genetic properties of Leuconostoc spp. In our laboratory, we cloned the genes responsible for citrate metabolism ( clyR mae citCDEFGOPcluster), for D-lactate dehydrogenase (ldhD) and for phosphotransacetylase ( pta). In addition we have planned to con- struct new vectors and we h…
