In primum librum Regum expositionum libri VI
No full textThe paper traces the misunderstandings of the commentary on the first book of Regum attributed to Gregory the Great. The history of the editions is analyzed till the discovery of the only manuscript known of the work, Cava dei Tirreni, Biblioteca dell'Abbazia 9. The criteria of the last edition by Patrick Verbraken are discussed as he uncritically favored the manuscript on the constitutio textus. The problem of the authorship of the work is investigated: although recent studies date the commentary to the twelfth century and ascribe it to Peter of Venosa on the basis of the Chronicon Venusinum, it is possible that the author used texts authentically gregorian
Eligio Castaldi
No full text25Castaldi worked for the Lands and Survey Department in Darwin for 18 months before leaving in March 1915 to take up a post with the Imperial Civil Service in Fiji. In 1930, he sold his gramophone, music and radio business at 161 Oxford Street, Bondi Junction and later won first prize in the Sydney lottery during 1935.Castaldi embarked from Sydney on board HMAT A14 'Euripides' on 31 October 1917. At his own expense, he left England for Malta on the 'Czaritza', 30 December 1918 and returned to Australia via the 'Ormonde' on 29 December 1919.SolicitorAustralian Imperial Force54th Battalion, 10th Reinforcement, Australian Army Ordnance CorpsMaltes
Scale Effects in the Artificial Reproduction of Natural Gas Hydrates in Lab Vessels
No full textNatural gas hydrates (NGHs), as the largest hydrocarbon resource on Earth, offer a promising reservoir of sustainable fuels, particularly due to the potential of the CO2-CH4 replacement process. Most of the literature on the study of NGHs comes from laboratory experimental campaigns using reactors for the artificial reproduction of the conditions in which NGHs form in nature. In order to develop production technologies at the field scale and also compare experimental results obtained in different setups, it is crucial to assess the effects that a particular geometry or size has on the results, from both thermodynamic and kinetic points of view. In this perspective, the paper compares the hydrate formation process carried out in two different reactors with similar cylindrical geometry, one with a volume of 1 L and the other with a volume of 60 L. The analysis covers, for two different values of hydrate saturation (10% and 20%), the thermal aspects, in order to understand how hydrates form and grow inside the reactor, the quantity of hydrate formed and gas uptake, and the kinetic aspects. At 10%, the formation front behaves differently between the two reactors, while at higher saturation, hydrates similarly form in the upper section of the reactor and subsequently advance to the lower section. With regard to gas uptake, it is higher in the small reactor, resulting in a higher utilization of the gas phase for hydrate formation. Also, the kinetics differs with size, especially at higher saturations. The pressure reduction rate is generally higher in the 1 L reactor
Le dediche di Giovanni Immonide
No full textThe flight from Rome of Formoso, bishop of Porto, on Easter night 876 and his subsequent conviction in the Roman synods are echoed in the dedication of the last two John the Deacon’s works, Vita Gregorii I papae and the rhythmic rewriting of the Cena Cypriani. The contribution reconstructs John Immonide’s figure, his role and his friendships within the cubiculum Lateranense, and analyzes the critical loci of the manuscript tradition of the dedication poem to Pope John VIII, prefacing the hagiographical text, and of the so called Epilogus and Suppositio closing the Cena. The sections analyzed show a tradition variously attested and not univocal, that is evidence of reworking and leads to suspect that the author has reviewed the dedications of his works when he was expelled from the Lateran, falled into disgrace with the pope, and he never reached a final version of them
Over-the-wire-technique device implantation
No full textIntroduction Transcatheter closure of cardiac defects is a mainstay of treatment in congenital and structural heart disease. Occasionally, the devices used are useful in nonstandard or difficult positions but device embolization and malposition can be complicating factors necessitating percutaneous retrieval or emergency surgery. We describe a new "over-the-wire" technique that allows guided safe deployment and easy retrievability if required. Methods We describe 5 cases in which Amplatzer devices were delivered over a wire in challenging anatomy in high-risk patients. These cases included baffle leak in complex congenital heart disease, paravalvular leak, a large patent ductus arteriosus, and complex ventricular septal defects. In each case, the device was punctured close to the release mechanism and a guidewire fed through it, the device and guidewire then being loaded into the appropriate delivery system. The procedure is described in each case, illustrating the use of the technique. Conclusion We describe a novel over-the-wire technique that is useful in deployment of Amplatzer devices in difficult and challenging anatomy, allowing careful controlled delivery and easy retrieval. This will help minimize procedural patient risk in complex cases. © 2012 Wiley Periodicals, Inc
A case of AndraStent®fracture in a patient with aortic coarctation: A review of the literature
No full textPercutaneous treatment of aortic coarctation is based on angioplasty and/or stenting of the isthmus. We report a case of a 28-year-old girl suffering from aortic coarctation syndrome (coarctation + ventricular septal defect + bicuspid aorta). She underwent coarctectomy with subclavian flap and pulmonary bandage followed by ventricular septal defect closure and bandage removal in her first year of life. When she was 27 years old, a follow-up echocardiography detected an isthmic pressure gradient and a demodulated Doppler in abdominal aorta. A cardiac catheterisation confirmed the diagnosis of aortic re-coarctation. An AndraStent® XL 48 mm was implanted with a resolution of the isthmic gradient. One year later, because of the reappearance of demodulated Doppler in abdominal aorta, a chest X-ray was performed, which showed a stent third-grade fracture. The fracture was corrected by positioning a covered stent cheatham platinum 45 mm through the fragments. The rarest complication after stenting procedures is the fracture of the device with an incidence between 0.01% and 0.08%. Pressure overload beyond the elastic threshold of the material and the pulsatile tension exerted by the blood flow on the walls of the stent are the main mechanisms at the base of the fracture, together with the compliance of the tissue. A vessel that underwent multiple surgical rearrangements could interfere with and complicate the physiopathology at the basis of the fracture. In conclusion, stenting is a safe technique to treat aortic coarctation; stent fracture is a rare event, and different anatomical and haemodynamic factors are related to this complication
Il giudizio di impugnazione dell'atto di diniego di iscrizione all'Anagrafe Onlus
No full textIl contributo, nel commentare una pronuncia della Corte di Cassazione, si sofferma ad analizzare le possibili correlazioni tra controllo formale e controllo sostanziale che l’Agenzia delle entrate è deputata a svolgere ai fini dell’iscrizione e successiva eventuale cancellazione di un ente dall’Anagrafe ONLUS. Si riflette altresì sulla portata – se agevolativa o ricognitiva di principio – da attribuire all’art. 143 co. 2 lett. b) t.u.i.r. laddove esclude l’imponibilità dei contributi corrisposti ad enti non commerciali da Amministrazioni pubbliche per lo svolgimento convenzionato o in regime di accreditamento di attività aventi finalità sociali conformemente alle finalità istituzionali dell’ente stesso
