LA STABILITÀ DEL FONDO DI SCAVI A PARETI VERTICALI SOSTENUTI DA DIAFRAMMI
2012
Nella presente nota si riportano i principali risultati di un’analisi dell’influenza sulla stabilità del fondo di scavi controventati dei seguenti fattori: stato tensionale iniziale; rapporto larghezza/altezza dello scavo; profondità di infissione dei diaframmi; attrito terreno-diaframmi; dissipazione delle sovrappressioni interstiziali. I risultati ottenuti indicano che le ipotesi semplificative poste a base dei metodi correntemente utilizzati per la valutazione delle condizioni di stabilità del fondo scavo portano spesso a sopravvalutare notevolmente il coefficiente di sicurezza.
Protective, antioxidant and antiproliferative activity of grapefruit integropectin on sh-sy5y cells
2021
Tested in vitro on SH-SY5Y neuroblastoma cells, grapefruit IntegroPectin is a powerful protective, antioxidant and antiproliferative agent. The strong antioxidant properties of this new citrus pectin, and its ability to preserve mitochondrial membrane potential and morphology, severely impaired in neurodegenerative disorders, make it an attractive therapeutic and preventive agent for the treatment of oxidative stress-associated brain disorders. Similarly, the ability of this pectic polymer rich in RG-I regions, as well as in naringin, linalool, linalool oxide and limonene adsorbed at the outer surface, to inhibit cell proliferation or even kill, at high doses, neoplastic cells may have open…
Evaluating the relationship between dental caries number and salivary level of IgA in adults
2017
Background Dental caries are the most common mouth infectious disease and also chronic disease of childhood. Saliva plays different roles in oral cavity; for example, salivary immunoglobulins play significant role in body and oral immunity. Various studies were conducted on the different effects of IgA on oral cavity, especially dental caries, and reported controversial results. The current study aimed to compare salivary IgA level at different stages of dental caries in adults. Material and Methods A total of 40 adults, aged 20 to 40 years, referred to the department of oral medicine at Qazvin Faculty of Dentistry, were selected voluntarily based on the number of decayed teeth. Their unsti…
Botulinum toxin in preparation of oral cavity for microsurgical reconstruction.
2010
CONCLUSIONS: Infiltration of botulinum toxin in the major salivary glands allows a temporary reduction of salivation that begins 8 days afterwards and returns to normal within 2 months. The inhibition of salivary secretion, carried out before the oral cavity reconstructive surgery, could allow a reduction of the incidence of oro-cutaneous fistulas and local complications. OBJECTIVES: Saliva stagnation is a risk factor for patients who have to undergo reconstructive microsurgery of the oral cavity, because of fistula formation and local complications in the oral cavity. The authors suggest infiltration of botulinum toxin in the major salivary glands to reduce salivation temporarily during th…
Estimation of Pyruvic acid in serum and saliva among healthy and potentially malignant disorder subjects – a stepping stone for cancer screening?
2014
Background: According to Warburg’s effect, the rate of glycolysis increases in cancerous cells. This will increase overall levels of pyruvic acid. The present on-going study was conducted to estimate the levels of pyruvic acid in saliva and serum in normal, oral PMD subjects. Material and Methods: A total of 50 subjects in healthy, PMD of the oral cavity individuals were selected based on clinical and histological criteria. Collected saliva and serum samples were subjected to pyruvic acid level estimation using biochemical analysis. Results: Of the 50 participants 25 (13: Males; 12: Females) & 25 (16: Males; 9: Females) were PMD group. Independent samples t test showed statistically signifi…
Role of saliva in oral food perception
2014
Saliva is the first fluid that comes into contact with food during oral processing. Because saliva is the medium that bathes the taste receptors, is the fluid through which taste and aroma compounds are released into the oral cavity and is mixed continuously with food during bolus formation, it is an essential actor in oral chemosensory perception. The complexity of saliva composition, with compounds originating from different salivary glands, from gingival crevicular fluid, from micro-organisms and from food debris, together with its variable nature increases the possibilities for interactions with food compounds and for different roles in perception. These factors are increasingly being t…

Nuove Ricerche a Castellazzo di Poggioreale. Campagne 2008-2009.
2012
Resoconto preliminare di due campagne di scavo nel sito indigeno di Monte Castellazzo, Valle del Belice, Sicilia. Viene descritto un muraglione con scalinata di età medievale costruito lungo il costone 540. Sono anche descritte le varie fasi di vita di una capanna protostorica di VIII-VII secolo a.C. e di un edificio a pianta rettangolare di età arcaica fine VII-VI sec. a.C. Sono infine illustrati gli interessantissimi reperti di un deposito di fondazione, comprendenti ceramica "elima" e greca di importazione, pesi da telaio, metalli allo stato grezzo e altri fittili di notevole qualità.
Simple scheme for extracting work with a single bath
2019
We propose a simple protocol exploiting the thermalization of a storage bipartite system S to extract work from a resource system R. The protocol is based on a recent work definition involving only a single bath. A general description of the protocol is provided without specifying the characteristics of S. We quantify both the extracted work and the ideal efficiency of the process, also giving maximum bounds for them. Then, we apply the protocol to two cases: two interacting qubits and the Rabi model. In both cases, for very strong couplings, an extraction of work comparable with the bare energies of the subsystems of S is obtained and its peak is reached for finite values of the bath tempe…
