MR2817222 Ursescu, Corneliu, A mean value inequality for multifunctions. Bull. Math. Soc. Sci. Math. Roumanie (N.S.) 54(102) (2011), no. 2, 193–200
2011
The paper is devoted to extend some mean value inequalities from the function setting to the multifunction one. Let (M,d) be a metric space, let F be a multifunctions defined on D \subset R and taking values in the family of nonempty subsets of M, and let g: D\rightarrow R be a strictly increasing function. The author proves the following inequality: \frac{\delta(F(b),F(a))}{g(b)-g(a)} \leq \sup_{s\in [a,b)\cap D} \sup_{S\in F(s)} \sup_{t\in (s,b)\cap D} \frac{\delta(F(t),S)}{g(t)-g(s)}, where a and b are two points of D with a<b and, if Q and P are nonempty subsets of M, then \delta(Q,P)=\sup_{p\in P} \inf_{q\in Q}d(q,p). An application of the previous inequality to the Dini derivatives of…
IL RUOLO DELLE AREE AGRICOLE NELLA PROGETTAZIONE TERRITORIALE. Gli aspetti sociali come forma di rivitalizzazione del territorio.
2014
La tesi indaga il tema della multifunzionalità applicata all’agricoltura come strumento per riattivare territori abbandonati, degradati, a rischio di uso improprio o di nuova edificazione. L’agricoltura ha sempre avuto un rapporto fondamentale con l’Uomo e con gli insediamenti. Il rapporto tra centri abitati e aree agricole è stato un rapporto di unione e di contrapposizione. Nel passaggio da agricoltura di sussistenza a quella di tipo intensivo e specializzato sono stati coinvolti gli spazi, le tecniche, gli strumenti, le opere legate all’attività agricola e, infine, il rapporto con il territorio. L’agricoltura, benché produca beni di prima necessità, nei decenni scorsi è stata considerata…
Parte II Capitolo I L'impresa agricola

this chapter examines the discipline of the agricultural enterprise in the light of the reform of the Italian civil code and the requests of European legislation towards the multifunctionality of the agricultural enterprise
Rational Chemical Multifunctionalization of Graphene Interface Enhances Targeted Cancer Therapy
2020
The synthesis of a drug delivery platform based on graphene was achieved through a step‐by‐step strategy of selective amine deprotection and functionalization. The multifunctional graphene platform, functionalized with indocyanine green, folic acid, and doxorubicin showed an enhanced anticancer activity. The remarkable targeting capacity for cancer cells in combination with the synergistic effect of drug release and photothermal properties prove the great advantage of a combined chemo‐ and phototherapy based on graphene against cancer, opening the doors to future therapeutic applications of this type of material.

Circular economy and agritourism: a sustainable behavioral model for tourists and farmers in the post-COVID era.
2023
Introduction: In recent years, issues related to environmental and ecosystem protection have been given greater consideration than in the past. The goal of adopting sustainable development models is vigorously pursued in the European Union and is reflected concretely in the new Common Agricultural Policy 20232027. The circular economy can certainly be an emerging economic response that can eectively replace growth models centered on a linear view. Agriculture and tourism are two crucial sectors where the “green transition” should be encouraged to help achieve sustainability goals through economic circularity. Agritourism’s activity may be relevant in contributing to a behavioral change based…
Solving Conflicts among Conservation, Economic, and Social Objectives in Boreal Production Forest Landscapes: Fennoscandian Perspectives
2018
This chapter discusses challenges and possibilities involved in preserving biological diversity and the diversity of ecosystem services in the boreal zone and yet at the same time maintaining intensive timber extraction in boreal forests. Our focus is on Fennoscandian forests at the landscapes level, and we consider economic, social and ecological in the sustainability of forest management. We provide an outlook to boreal forest ecosystems and their history, and an overview of the forestry practices and policies that aim to ensure multi-functionality of Fennoscandian forests, i.e. diversity of efforts on sustaining biodiversity, timber production and other ecosystem services from forest lan…
Développement territorial et développement agricole durable
2012
L'objectif de la communication est de montrer comment au travers d'une approche pluri-disciplinaire, l'ancrage territorial de l'agriculture est une clé de compréhension de la durabilité de l'agriculture de territoires mixtes, périurbains ou ruraux-touristiques. La dimension socio-spatiale qu'introduit cet angle d'analyse conduit à rapprocher géographie et agroéconomie au sein d'une démarche qui vise à modéliser la complexité et la multi-dimensionnalité du développement agricole. Cette approche est appliquée à un territoire dominé à la fois par l'agriculture et le développement touristique, situé en Corse (Balagne). L'agriculture, entre pression foncière et valorisation touristique du patrim…
From agricultural to tourist production
2010
This contribution starts off from taking account of the crisis in the agricultural sector. This sector has been “trivialised” by erroneous policies and market rules. However, at present the trend is changing: “demand for environment” is increasing, as well as the attempt of taking actions and policies favouring sustainable development. At the same time, notwithstanding the different meanings attached to the concept of sustainability, a wave of revaluation of rural areas is rising: the countryside is now considered as a source of local cultural values. Its exploitation as a tourist attraction, which is progressively taking off, is to be considered in this context. Natural and cultural assets…
