¿Son los adhesivos dentinarios una opción válida para el tratamiento de la sensibilidad cervical dentinaria?

2006

espanolEl objetivo de este trabajo es evaluar la capacidad in vitro de sellar tubulos dentinarios y reducir la permeabilidad dentinaria que tienen catorce productos propuestos para el tratamiento de la sensibilidad cervical dentinaria (SCD) y evaluar el efecto que la humedad y el cepillado tienen sobre ellos. Material y metodo: 140 discos de dentina (obtenidos de 3o molares humanos recien extraidos) se dividen en catorce grupos de 10 discos que se montan en un sistema de perfusion basado en la maquina de Pashley que mantiene una presion positiva sobre las discos. Cada disco se graba con acido ortofosforico al 35% y su permeabilidad se mide en una hora, este valor se considera el de referenc…

An organelle-specific protein landscape identifies novel diseases and molecular mechanisms.

2016

Cellular organelles provide opportunities to relate biological mechanisms to disease. Here we use affinity proteomics, genetics and cell biology to interrogate cilia: poorly understood organelles, where defects cause genetic diseases. Two hundred and seventeen tagged human ciliary proteins create a final landscape of 1,319 proteins, 4,905 interactions and 52 complexes. Reverse tagging, repetition of purifications and statistical analyses, produce a high-resolution network that reveals organelle-specific interactions and complexes not apparent in larger studies, and links vesicle transport, the cytoskeleton, signalling and ubiquitination to ciliary signalling and proteostasis. We observe sub…

Fostering Entrepreneurs’ Capabilities to Outline Sustainable Strategies in ‘Stunted’ SMEs through Modelling and Simulation: a Dynamic Resource Based …

The literature recognises the phenomenon of ‘dwarf’ or ‘stunted’ small and micro firms (in Italian nanismo aziendale) and that they might represent potential lost opportunities for owners and the local economy. Based on a field survey conducted by Bianchi et al. (2003) and the analysis previously developed by the authors of this paper in sketching a simple ‘insight’ model to simulate the behaviour of such firms (Bianchi & Winch, 2005), this work aims to show further research developments in the effort to better understand the business dwarfism phenomenon. A system dynamics model replicating the basic no-growth, cyclical behaviour attributed to “stunted” SMEs is firstly analysed. Alterna…

Structural Growth Disengagement and value creation in small and micro-firms. Mapping pathologies and physiologies of business dwarfism in a dynamic r…

This paper focuses growth disengagement, in the perspective of those firms who have been keeping their structures, processes and relational systems unchanged for a very long time. The implicit hypothesis according to which such businesses are affected by a structural disease, are not able to create any significant value, and characterised by similar features, is critically discussed. Through an analysis of the phenomenon in the business growth and dynamic resource-based-view, a first attempt taxonomy, based on case-studies, is sketched. It is demonstrated how the implicit assumption according to which such firms are affected by a pathological condition is false, at least if seen as an a pri…

Suicidi

2020

I suicidi, eventi drammatici come pochi altri, hanno da sempre costituito una sfida per l’immaginazione sociologica. Se Emile Durkheim aveva dimostrato le capacità esplicative della sociologia, le sociologie costruzioniste – e, in particolare, interazionismo simbolico, etnometodologia, fenomenologia – hanno operato la resa dei conti con gli approcci positivisti. I saggi che qui presentiamo offrono una summa di grande interesse dei modi originali con cui le sociologie costruzioniste hanno re-immaginato lo studio dei suicidi andando oltre la rigidità dello schema “cause e cure” degli approcci positivisti ed arricchendo di sfumature la nostra comprensione del fenomeno. Di fronte a un panorama …

Hydraulic kinetics of the graft union in different Olea europaea L. scion/rootstock combinations

2007

The hydraulic resistance of young olive trees grafted on rootstocks with contrasting size-controlling potential was measured 30, 90, 360 and 480 days after grafting. Olive (Olea europaea L.) clones inducing plant vigorous growth (Leccino ‘Minerva’, LM) or dwarfing (Leccino ‘Dwarf’, LD) were studied in different scion/rootstock combinations (LD/LD, LD/LM, LM/LD, LM/LM). Plants growing on LD root systems developed lower leaf surface areas (about 50% less) than plants grafted on LM rootstocks. Graft union represented the largest fraction (up to 85%) of whole-plant hydraulic resistance 30 days after grafting, and still represented an important fraction of it 2 months later (40–55%). Four-hundre…

Graft union represented the largest fraction (up to 85%) of whole-plant hydraulic resistance 30 days after grafting and still represented an important fraction of it 2 months later (40–55%). Four-hundred and eighty days after grafting the hydraulic resistance of the graft union became negligible (<3%) with no difference among the different scion/rootstock combinations. Our data reinforce the idea of graft hydraulics not playing a role in depressing the vigour of the scion as observable in adult plants grafted onto dwarfing rootstocks. The long time required for the vascularisation to be complete on the contrary represents the main risk for successful olive breeding.food and beveragesOlea europaea LGraft hydraulic resistanceDwarfingPlant ScienceRoot systemHPFMHydraulic resistancebiology.organism_classificationGraftingDwarfingOlive treesHorticultureOleaOleaceaeBotanyGraft hydraulic resistance; Olea europaea L.; Dwarfing; Scion; Rootstock; HPFMRootstockRootstockAgronomy and Crop ScienceEcology Evolution Behavior and Systematics

Etica della popolazione. Sul ruolo delle intuizioni morali

2019

In questa tesi vengono analizzati i principali argomenti per risolvere i paradossi dell'etica della popolazione (dibattito di etica normativa). Gli argomenti vengono suddivisi in due stili rispondenti a regole diverse. Segue un'analisi sul piano metodologico dei due stili morali, presentati come due modi di intendere la ricerca rawlsiana di un equilibrio riflessivo. Dopo aver messo a fuoco le differenze principali tra questi due stili viene avanzata la tesi secondo la quale uno di essi sia il metodo di indagine normativa proprio del Soggettivismo (tesi per cui le ragioni che abbiamo per agire dipendono dalle nostre proattitudini teliche). In this work the main arguments that have been put f…

Muhammad Sa'id al-'Arfi (1896-1956). Mufti del Wadi al-Furat territorio di "confine".

2012

Scopo di questo contributo è concorrere a definire il ruolo di uomo di scienza musulmano o ‘ālim attivo in epoca contemporanea ed in un’area considerata periferica e/o marginale, nonché di confine, attraverso la ricostruzione dei dati biografici e cenni all’opera dello shaykh Muḥammad Sa‘īd al-‘Arfī, muftì della Valle dell’Eufrate e di Dayr al-Zūr. Quella di al- ‘Arfi, e non di al-‘Urfī come si potrebbe pensare, è figura poco conosciuta e la sua opera rimane poco esplorata nel quadro degli studi di storia politica, religiosa e giuridica, culturale nella stessa Siria. È significativo il mistero che avvolge la sorte di una sua “Storia di Dayr al-Zūr”, introvabile ma di cui i membri della fami…
