Systemic silviculture and Mediterranean forest complexity: the need for a new paradigm in forestry

2011

La crescente minaccia di riduzione, semplificazione e scomparsa dei fondamentali caratteri di diversita biologica che caratterizza l’ambiente mediterraneo, e segnatamente le sue formazioni forestali, rende necessario rivedere le strategie di intervento colturale e gestione. In passato hanno prevalso, in specie nei boschi pubblici, forme di gestione e di applicazione della selvicoltura alquanto semplificate e volte a massimizzare soprattutto la funzione produttiva e a “normalizzare “ le formazioni forestali. Viceversa emerge sempre piu chiaramente la complessita dei sistemi mediterranei. Pertanto e necessario uscire dagli schemi preordinati e adottare un approccio che comprenda e rispetti ta…

Germacranolides and a monoterpene cyclic peroxide from Artemisia fragrans

1998

Abstract The aerial parts of Artemisia fragrans collected in Armenia yielded a new cyclic monoterpene peroxide with the irregular santolinyl framework, together with several known germacranolides. Comparison with previously published chemical results suggests these may actually have been performed on a different, although closely related species.

Gesture recognition using low-cost devices: Techniques, applications, perspectives

2016

Negli ultimi anni abbiamo assistito ad una grande diffusione dei cosiddetti “Kinect-like devices”, ovvero dispositivi basati su un insieme di sensori a basso costo, che consentono di ottenere un’immagine di profondità della scena ripresa. L’alta accessibilità di questi dispositivi, principalmente in termini di costi, ne ha facilitato la diffusione nell’ambito del riconoscimento dei gesti in numerose applicazioni, sia commerciali che di ricerca. In questo articolo saranno inizialmente illustrati i principi generali su cui si fondano le principali tecniche utilizzate per riconoscere i gesti, sfruttando i dati ottenibili dai dispositivi “Kinect-like”. Successivamente, saranno presentati alcuni…

Gingivitis

2021

Gingival inflammation is caused by bacterial plaque (dental biofilm) that accumulates daily on the teeth. Results in redness, slight swelling, or "puffiness" of the gums and bleeding on tooth brushing. Treatment involves thorough professional tooth cleaning and effective daily removal of dental plaque by tooth brushing and cleaning between the teeth. Necrotizing gingivitis is a more serious condition that is mainly found in developing countries and is associated with people with severe malnutrition or people living with HIV with low CD4 counts.

Gingival inflammation is caused by bacterial plaque (dental biofilm) that accumulates daily on the teeth. Results in redness, slight swelling, or "puffiness" of the gums and bleeding on tooth brushing. Treatment involves thorough professional tooth cleaning and effective daily removal of dental plaque by tooth brushing and cleaning between the teeth. Necrotizing gingivitis (NG) is a more serious condition that is mainly found in developing countries and is associated with people with severe malnutrition or people living with HIV with low CD4 counts.

Teratogenicity and Developmental Toxicity of Herbal Products

2017

Developmental toxicology and research in teratogenicity focus on xenobiotic substances that damage embryos and fetuses and lead to death, growth retardation, and/or malformation of offspring. While considerable information has been acquired about synthetic drugs and environmental xenobiotics, much less is known about the teratogenicity of herbal products. In this chapter we report on some major topics of developmental toxicity and teratogenicity, and discuss the safety of a few selected medicinal herbs in this context, i.e., Artemisia annua L., Caulophyllum thalictroides (L.) Michx., Echinacea spec,. Glycyrrhiza spec., herbs derived from Chinese medicine, Hypericum perforatum L., Panax gins…

General Overview

2016

Il capitolo introduce alla tematica smart city attraverso un exscursus storico che ne traccia i passaggi salienti: la nascita delle politiche globali ambientali sino al livello della maturità raggiunto con il Protocollo di Kyoto (1997); poi ancora il Pacchetto Clima 20-20-20 redatto dalla Commissione Europea nel 2008 che traccia un'altro punto cruciale che prelude ai progetti e alle iniziative in ambito smart cities. La Strategia Energetica Europea al 2050 rappresenta il quadro di riferimento a cui tendere. Il capitolo si conclude con una rassegna dei sistemi di ranking più popolari e con una proposta di analisi. The chapter introduces to smart city issue through a historical excursus, whic…
