Waste heat recovery from a marine waste incinerator using a thermoelectric generator

2012

Published version of an article published in the journal: Journal of Electronic Materials. Also available from the publisher at: http://dx.doi.org/10.1007/s11664-012-2009-6 A marine waste incinerator has been evaluated for waste heat harvesting using thermoelectric generators (TEG). The application has been evaluated using mathematical modeling to optimize the heat exchanger and some vital design parameters of the TEG. The calculation shows that it is possible to extract 58 kW el at a price of 6.6 US$/W from an 850-kW th incinerator when optimizing for maximum power. However, minimizing the cost, it is possible to get 25 kW el at a price of 2.5 US$/W. A trade-off between the two targets lea…

NH4HCO3–water solutions regeneration in RED closed loop applications

2017

Reverse Electrodialysis (RED) in closed loop arrangement (Reverse Electrodialysis Heat Engine - REDHE) is a promising technology to convert low-grade waste heat into electricity. RED is a membrane process exploiting the salinity gradient between a concentrated and a diluted solution to generate electrical current. Due to the transfer phenomena occurring in the RED unit, the two exiting solutions are partially mixed. Thermal regeneration processes can be used to restore the initial conditions of the two solutions, thus closing the loop. In this regard, ammonium hydrogen carbonate (NH4HCO3) salt solutions are suitable for such applications, being able to decompose at temperatures above 40-45 …

Comparison of the mycelial growth of some Phellinus spp. isolates on different agar media

2017

Celem pracy było określenie i porównanie wzrostu grzybni Phellinus spp. Użyto dziewięciu izolatów z gatunków: P. torulosus, P. robustus, P. pomaceus, P. igniarius i P. pini, które uprawiano na czterech różnych pożywkach agarowych, aby określić ich przydatność dla rodzaju Phellinus. Zastosowano pożywki: ziemniaczano-glukozową (PDA), maltozową (MEA), pszenną (WA) i trocinowo-pszenną (SWA). Po 10 dniach inkubacji w 25°C zmierzono średnice kolonii. Artykuł prezentuje dane dotyczące wzrostu grzybni (G) i krótkie opisy koloni na MEA. Wszystkie izolaty wykazały mały wzrost na MEA i duży wzrost na WA, SWA i PDA. Wzrost grzybni wszystkich izolatów na poszczególnych pożywkach wyniósł odpowiednio: MEA…

A two-sided kingdom: a Sicily of export and urban grain supply

2020

The Sicilian provisioning system sought to guarantee both the subsistence of cities and the income of the great aristocratic landowners interested in the wheat market. A set of economic mechanisms, social practices and political conflicts unfolded around the urban Annonas, dealing with wheat and flour distribution, bread production, contracts for the procurement of supplies, and the price system of the mete, run by political élites. North-eastern Sicily was exclusively consumer, while the west central area produced surpluses for the foreign market and for the rest of the island, including the capital Palermo, and Messina, a rich and hungry city. The centralized office of the Maestro Portula…

Predominance of Type 1 Innate Lymphoid Cells in the Rectal Mucosa of Patients With Non-Celiac Wheat Sensitivity: Reversal After a Wheat-Free Diet.

2016

OBJECTIVES: Non-celiac wheat sensitivity (NCWS) is defined as a reaction to ingested wheat after exclusion of celiac disease and wheat allergy. As its pathogenesis is incompletely understood, we evaluated the inflammatory response in the rectal mucosa of patients with well-defined NCWS. METHODS: The prospective study included 22 patients with irritable bowel syndrome (IBS)-like clinical presentation, diagnosed with NCWS by double-blind placebo-controlled challenge. Eight IBS patients not improving on wheat-free diet were used as controls. Two weeks after oral challenge was performed with 80 grams of wheat daily, cells were isolated from rectal biopsies and thoroughly characterized by fluore…

I MONUMENTI AI SOVRANI SPAGNOLI IN SICILIA NELLA SECONDA METÀ DEL SEICENTO: IL CASO DI FILIPPO IV A PALERMO E DI CARLO II A MESSINA

2018

I MONUMENTI AI SOVRANI SPAGNOLI IN SICILIA NELLA SECONDA METÀ DEL SEICENTO: IL CASO DI FILIPPO IV A PALERMO E DI CARLO II A MESSINA-Nella seconda metà del Settecento vennero eretti in Sicilia due grandiosi monumenti per celebrare gli ultimi re di Spagna della Casa d'Asburgo: il “teatro” di Filippo IV nel piano del palazzo Reale di Palermo (dal 1661) e il gruppo scultoreo con la statua equestre di Carlo II (dal 1680) nella piazza della cattedrale di Messina. I due monumenti rendevano omaggio in Sicilia, nei luoghi eletti simbolo del potere della corona spagnola, i trionfi di sovrani ancora in vita e secondo parametri compositivi articolati e meritevoli di attenzione. L’adozione di un reperto…
