On thermoeconomics of energy systems at variable load conditions: integrated optimization of plant design and operation
2007
Abstract Thermoeconomics has been assuming a growing role among the disciplines oriented to the analysis of energy systems, its different methodologies allowing solution of problems in the fields of cost accounting, plant design optimisation and diagnostic of malfunctions. However, the thermoeconomic methodologies as such are particularly appropriate to analyse large industrial systems at steady or quasi-steady operation, but they can be hardly applied to small to medium scale units operating in unsteady conditions to cover a variable energy demand. In this paper, the fundamentals of thermoeconomics for systems operated at variable load are discussed, examining the cost formation process an…
A systematic review on external ear melanoma
2014
Summary Background External ear melanoma accounts for only 1% of all cutaneous melanomas, and data on its optimal management and prognosis are limited. Aim We aim to review the literature on external ear melanoma to guide surgeons in the treatment of this uncommon and peculiar pathology. Materials and methods A systematic review of English language studies on ear melanoma published from 1993 to 2013 was performed using the PubMed electronic database. Data on epidemiology, oncological treatment (tumor resection and regional lymph nodes management), and reconstruction were extrapolated from selected papers. Results The total number of patients was 858 (30 studies). The helix was the most comm…
MALIGNANT EXTERNAL OTITIS. A CASE SERIES FROM AN ITALIAN TERTIARY-CARE HOSPITAL
2014
Objectives: Malignant external otitis (MEO) is an. aggressive and potentially fatal disease that affects the external. auditory canal (EAC) it occurs almost exclusively in elderly, diabetic patients or immune compromised ones. The aim of this study was to describe epidemiological and clinical characteristics of a consecutive series of patients affected by malignant external otitis (MEO) and to conceive a flow-chart for its management. Material and methods: Adult patients diagnosed with and treated for MEO at the University Hospital of Messina, Italy between 2003 and 2013 were identified. Charts were reviewed for history, clinical presentation, laboratory data treatment, and outcomes. Result…
Chronic progressive external ophthalmoplegia with a novel mitochondrial DNA deletion and a mutation in the tRNALEU(UUR) gene
1999
Large-scale deletions and point mutations of the mitochondrial DNA are generally accepted as being involved in the pathogenesis of diseases associated with mitochondrial encephalomyopathies such as Kearns-Sayre syndrome and chronic progressive external ophthalmoplegia (CPEO). We screened suspected patients using polymerase chain reaction techniques, Southern blot analyses, and muscle biopsy specimens. We report on a novel 4,953-base pair deletion associated with a familial occurrence of a tRNA Leu(UUR) T3250C point mutation in a young female patient clinically diagnosed with CPEO. This deletion is not flanked by direct repeats, so slip replication and homologous recombination do not seem li…
Comparing DNA sequence collections by direct comparison of compressed text indexes
2012
Popular sequence alignment tools such as BWA convert a reference genome to an indexing data structure based on the Burrows-Wheeler Transform (BWT), from which matches to individual query sequences can be rapidly determined. However the utility of also indexing the query sequences themselves remains relatively unexplored. Here we show that an all-against-all comparison of two sequence collections can be computed from the BWT of each collection with the BWTs held entirely in external memory, i.e. on disk and not in RAM. As an application of this technique, we show that BWTs of transcriptomic and genomic reads can be compared to obtain reference-free predictions of splice junctions that have h…
William J. Morgan’s ‘conventionalist internalism’ approach. Furthering internalism? A critical hermeneutical response
2014
Several authors, such as William J. Morgan, John S. Russell and R. Scott Kretchmar, have claimed that the limits between the diverse normative theories of sport need to be revisited. Most of these works are philosophically grounded in Anglo-American philosophical approaches. For instance, William J. Morgan’s proposal is mainly based on Richard Rorty’s philosophy. But he also discusses with some European philosophers like Jurgen Habermas. However, Habermas’ central ideas are rejected by Morgan. The purpose of this paper is to analyse Morgan’s rejection of Habermas’ thought and show that a more appropriate normative of sport that explains better our current sporting world can be achieved by d…
A simple method for the photometric characterization of organic light-emitting diodes
2022
A simple method for the photometric characterization of organic light-emitting diodes (OLEDs) is reported. It is based on the indirect measurement of the total emitted optical power by using a calibrated photodiode and the optical emission spectrum and space emission diagram of the OLED. From this and by measuring the current–voltage characteristic of the OLED all the relevant radiometric and photometric quantities can be extracted, including the external quantum efficiency. The usual method to collect all photons emitted by a LED source in the half space uses an integrating sphere with the LED source placed at the entrance hole and a photodiode (PD) placed at an exit hole at some point on …
The time course of face matching by internal and external features: Effects of context and inversion.
2010
AbstractEffects of context and inversion were studied in face matching tasks by measuring proportion correct as a function of exposure duration. Subjects were instructed to attend either internal features (task A) or external features (task B) and matched two consecutive face stimuli, which included either congruent, incongruent, or no facial context features. In congruent contexts matching performance rose fast and took very similar courses for both types of facial features. With no contexts internal and external features were found to be matched at an equal speed, while incongruent contexts seriously delayed matching performance for internal, but not for external features. Analysing the e…
„Dyplomatyczna Republika Europy”?
2018
‘Diplomatic Republic of Europe’? Reflections on the Impact of Selected Lisbon Solutions on EU Diplomacy in a Multilateral International Environment The aim of the reflections in this article is to analyze the impact of selected institutional solutions adopted by the Treaty of Lisbon on the EU diplomacy in contemporary international relations. The article does not refer to all regulations that concern broadly defined EU External Policy, but those which, by the nature of their connections, content of competence and meaning, became the object of special interest of the treaty architects and whose implementation was to counteract deficits in continuity, coherence and leadership in EU External P…
DELL’UTRI E CONTRADA “GEMELLI DIVERSI”: È LA REVISIONE EUROPEA LO STRUMENTO DI OTTEMPERANZA ALLE SENTENZE CEDU
2017
La Cassazione nega l’origine giurisprudenziale del concorso esterno in associazione mafiosa e individua il rimedio della revisione europea per l’attuazione della decisione CEDU nei confronti di soggetti in posizioni simili a quella di Contrada. Il percorso offre l’occasione per riflettere sulla connotazione “oggettiva” della prevedibilità e sull’uguaglianza di trattamento dei condannati. Italian supreme Court denies that the origin of external participation in mafia-type criminal association lies in case law and envisages the European review as the tool to comply with ECtHR judgements in similar cases to that of Contrada. This jurisprudence provides a proper opportunity for an in-depth exam…
