Il limite della buona fede nell'applicazione della clausola "simul stabunt simul cadent"
2013
La pronuncia in commento s’inserisce nel recente orientamento del Tribunale di Milano secondo il quale l’utilizzo della clausola ‘‘simul stabunt simul cadent’’ al solo fine di estromettere uno o piu` amministratori dalla gestione della societa` costituisce una violazione della buona fede nei rapporti endosocietari. La sentenza offre un’ulteriore occasione per riflettere sui limiti di utilizzo della suddetta clausola statutaria, consentendo all’interprete di prospettare in quest’ambito ulteriori sviluppi applicativi della clausola generale di buona fede e dell’abuso del diritto
Sea urchin embryos cadmium exposed as an experimental model system for studying the relationship between autophagy and apoptosis

Studio della sequestrazione dello ione cadmio da parte di leganti s-donatori
2010
La presenza in natura del cadmio è dovuta principalmente al suo uso in svariati settori dell’industria [1] ed in misura minore al suo rilascio durante i processi di demineralizzazione delle rocce. La elevata tossicità dello ione cadmio [2] nei confronti degli esseri viventi, animali e vegetali, è dovuta alla elevata affinità che questo catione mostra nei confronti della maggior parte dei gruppi leganti presenti nelle molecole biologicamente attive. In particolare i leganti tiolici presenti nei residui amminoacidici, soprattutto quelli a basso peso molecolare rappresentano i vettori principali attraverso il quale avvengono i fenomeni di trasporto e di distribuzione del cadmio nell’organismo …
Nomenclature for Hydrogeological Instability Risks
2022
The nomenclature for hydrogeological instability risks includes four main risks, which are distinguished according to the risk causes : 1) hydrogeological risk, that is slowly caused by natural factors (e.g. collapse landslides in a calcareous cliff in uninhabited areas and erosion along a marly-calcareous slope) in environments where human activities are minimal, i.e. woods, forests and mountain pastures; 2) hydraulic-pedological farming risk, that implies the occurrence of landslides in every winter and is caused by incorrect crop selection, not suitable for the soil and climate parameters (e.g. on a hilly slope with a clay vertisol type with a landslide having different fronts, when the …
THE STRUCTURE OF SOIL CADASTRE. A MODEL OF SOIL INVENTORY FOR ENVIRONMENTAL, SOCIAL, ECONOMIC AND TAXATION PURPOSES IN A GLOBALISED MARKET
2018
The author shows the development of a structure, derived from the processing and integration of Ground Cadastre, where all soil characteristics are described. The soil is considered as divided according to the updated concept of cadastral parcel (soil and topographic uniformity of ownership and municipality). The land use is also assessed with reference to sustainability, taxation and environmental risk prevention. The structure of Soil Cadastre can contribute to the bureaucratic simplification of agricultural policies and environmental emergencies, as well as product presentation and traceability. Through the updating of some characteristics by professionals, the cadastre can become eviden…
Analysis of the effects of co-exposure to antibiotics and cadmium on sea urchin embryos
2014
In order to understand the mechanisms of responses to changes in the physical and chemical environment, as well as the mechanisms of developmental pathways, we investigated by RT-qPCR assays and light microscopy observations the impact of antibiotics and cadmium in P. lividus sea urchin embryos. In particular we inspected development and biomarkers for free radical damage and apoptosis. During development embryos were exposed to an antibiotic mix (Ab mix, usually added to sea urchin cultures) or to sulfamethoxazole/trimethoprim mix (TMP/SMX, usually added to aquacultures) and/or levels of 10-5, 10-4, 10-3 M CdCl2. Even though treatment with TMP/SMX apparently did not affect development, it …
A DISSECTION'S GUIDE TO HUMAN ABDOMINAL CAVITY
2020
The purpose of this article is to show the abdominal cavity's dissection method. In the summer of 2018 a group of students from the University of Palermo, who had already taken the anatomy exam and had good knowledege of English, went for a period of two weeks to do a dissection course at the University of malta. The students dissected skin, subcutaneously, muscle layers, parietal peritoneum and abdominal organs. this works proves to be a small dissection guide for young medical students who want to learn the main bases of dissection and important information for topographical anatomy.
A BRIEF ANATOMO-SURGICAL DISSECTION GUIDE TO HUMAN LOWER LIMB: RESULTS OF THE COLLABORATION BETWEEN THE UNIVERSITY OF PALERMO AND THE UNIVERSITY OF M…
2020
The aim of this Article is to show methods for dissection of the lower limb. In the summer 2017 a group of students at the University of Palermo that have already passed the exam of Human Anatomy took a 4 weeks dissection course at the University of Malta - School of Medicine. The students were provided with a dissection kit, video recording equipment and cameras for taking pictures. This paper presents the results of the dissection course and a small and simple guide to young students and medical doctors who want to learn the bases of lower limb dissection.
El pòlip de Trembley: L'"animal-planta" que va sacsejar la biologia del segle XVIII
2013
Els experiments d’Abraham Trembley amb l’hidra d’aigua dolça no només van sorprendre els seus contemporanis per la seva espectacularitat, sinó que els seus resultats també van causar un enorme trasbals en la comunitat científica del seu temps. Idees com la «cadena del ser», el mecanisme de generació dels éssers vius o la mateixa naturalesa de l’ànima van ser fortament sacsejades.
