Effect of hydrodynamics and surface roughness on the electrochemical behaviour of carbon steel in CSG produced water

The influence of fluid flow, surface roughness and immersion time on the electrochemical behaviour of carbon steel in coal seam gas produced water under static and hydrodynamic conditions has been studied. The disc electrode surface morphology before and after the corrosion test was characterized using scanning electron microscopy (SEM). The corrosion product was examined using X-ray photoelectron spectroscopy (XPS) and X-ray diffractometry (XRD).The results show that the anodic current density increased with increasing surface roughness and consequently a decrease in corrosion surface resistance. Under dynamic flow conditions, the corrosion rate increased with increasing rotating speed due to the high mass transfer coefficient and formation of non-protective akaganeite β- FeO(OH) and goethite α- FeO(OH) corrosion scale at the electrode surface.The corrosion rate was lowest at 0 rpm.The corrosion rate decreased in both static and dynamic conditions with increasing immersion time. The decrease in corrosion rate is attributed to the deposition of corrosion products on the electrode surface. SEM results revealed that the rougher surface exhibited a great tendency toward pitting corrosion.

Símbolos helenísticos del poder en la concepción imperial de Calígula

Abstract: The way of exercising power of the Roman Princeps Gaius Caesar Augustus Germanicus, better known by his agnomen Caligula, was largely driven by a different pattern of behavior of that promoted by his predecessors Augustus and Tiberius. Through a kind of ritualized acts, these princeps sought to show respect for the traditional social order and appear only as a primus inter pares among Roman aristocrats. As we can see, in this matter the young Gaius caused a radical change on imperial politics. From the valuation of a series of symbols and actions with strong symbolic connotations, in this work we will attempt to show that such a change was, in part, consequence of a new conception of the imperial power displayed by Caligula. The essence of such conception we must search it in the complex corpus of ideas that came to Rome from the pars orientis of the Roman Empire and based important aspects of the power of the Hellenistic Monarchies

Los ludi en la Roma arcaica

Resumen: En este artículo se analizan los juegos públicos celebrados en Roma durante el período monárquico. Su creación obedece a motivos religiosos, en relación a la fecundidad (Consualia, ludi Taurei) o a la guerra (Equirria, equus October). La culminación religiosa y política de los juegos se materializa en los ludi Romani, institutidos por el rey Tarquinio Prisco. Finalmente es considerado también el llamado lusus Troiae, juego ecuestre exclusivo de los jóvenes y asimismo de origen arcaico.

Osteometric analysis of the scapula and humerus of Rangifer tarandus and Cervus elaphus : A contribution to the discrimination of Late Pleistocene cervids

Fossil remains of reindeer (Rangifer tarandus) occurring outside their present range are an important indicator of formerly cold climatic conditions, but are easily confused with those of the red deer (Cervus elaphus). The locality of Kiputz IX has yielded one of the best-preserved Late Pleistocene reindeer populations of the southern Pyrenees, occurring in association with Bison priscus and the much more abundant Cervus elaphus. Fossil remains from this site are mostly complete and not affected by human intervention, thus creating the perfect conditions for reliable osteometric analyses. Here, we quantify diagnostic morphological features of the scapula and the humerus of Cervus elaphus and Rangifer tarandus to establish the potential of these bones to aid in interspecific discrimination. In the case of the scapula, the best species discriminator is the ratio of the minimum anteroposterior diameter of the scapular neck and the development of the articular process, while the breadth of the trochlea is the best discriminator in the case of the humerus.

Pharmacotherapy optimization in older patients by a structured clinical pharmacist assessment and intervention

Introduction: Older individuals are particularly vulnerable to potentially inappropriate prescribing (PIP), drug related problems (DRPs) and adverse drug reactions (ADRs). A number of different interventions have been proposed to address these issues. However to-date there is a paucity of well-designed trials examining the impact of such interventions. Therefore the aims of this work were to: (i) establish a baseline PIP prevalence both nationally and internationally using the STOPP, Beers and PRISCUS criteria, (ii) identify the most comprehensive method of assessing PIP in older individuals, (iii) develop a structured pharmacist intervention supported by a computer decisions support system (CDSS) and (iv) examine the impact of this intervention on prescribing and incidence of ADRs. Results: This work identified high rates of PIP across all three healthcare settings in Ireland, 84.7% in the long term care, 70.7% in secondary care and 43.3% in primary care being reported. This work identified that for a comprehensive assessment of prescribing to be undertaken, an amalgamation of all three criteria should be deployed simultaneously. High prevalences of DRPs and PIP in older hospitalised individuals were identified. With 82.0% and 76.3% of patients reported to have at least one DRP or PIP instance respectively. The structured pharmacist intervention demonstrated a positive impact on prescribing, with a significant reduction MAI scores being reported. It also resulted in the intervention patients’ having a reduced risk of experiencing an ADR when compared to the control patients (absolute risk reduction of 6.8 (95% CI 1.5% - 12.3%)) and the number needed to treat = 15 (95% CI 8 - 68). However the intervention was found to have no significant effect on length of stay or mortality rate. Conclusion: This work shows that PIP is highly prevalent in older individuals across three healthcare settings in Ireland. This work also demonstrates that a structured pharmacist intervention support by a dedicated CDSS can significantly improve the appropriateness of prescribing and reduce the incidence of ADRs in older acutely ill hospitalised individuals.

Consensus statements for management of Barrett's dysplasia and early-stage esophageal adenocarcinoma, based on a Delphi process

Esophageal adenocarcinoma (EA) is increasingly common among patients with Barrett's esophagus (BE). We aimed to provide consensus recommendations based on the medical literature that clinicians could use to manage patients with BE and low-grade dysplasia, high-grade dysplasia (HGD), or early-stage EA.

The latest LGM culmination of the Garda Glacier (Italian Alps) and the onset of glacial termination. Age of glacial collapse and vegetation chronosequence

In the deglacial sequence of the largest end moraine system of the Italian Alps, we focused on the latest culmination of the Last Glacial Maximum, before a sudden downwasting of the piedmontane lobe occupying the modern lake basin. We obtained a robust chronology for this culmination and for the subsequent deglacial history by cross-radiocarbon dating of a proximal fluvioglacial plain and of a deglacial continuous lake sedimentation. We used reworked dinocysts to locate sources of glacial abrasion and to mark the input of glacial meltwater until depletion. The palynological record from postglacial lake sediments provided the first vegetation chronosequence directly reacting to the early Lateglacial withdrawal so far documented in the Alps.

Glacier collapse occurred soon after 17.46 +/- 0.2 ka cal BP, which is, the Manerba advance culmination. Basin deglaciation of several overdeepened foreland piedmont lakes on southern and northern sides of the Alps appears to be synchronous at millennial scale and near-synchronous with large-scale glacial retreat at global scale. The pioneering succession shows a first afforestation step at a median modeled age of 64 years after deglaciation, while rapid tree growth lagged 7 centuries. Between 16.4 +/- 0.16 and 15.5 +/- 0.16 ka cal BP, a regressive phase interrupted forest growth marking a Lateglacial phase of continental-dry climate predating GI-1. This event, spanning the most advanced phases of North-Atlantic H1, is consistently radiocarbon-framed at three deglacial lake records so far investigated on the Italian side of the Alps. Relationships with the Gschnitz stadial from the Alpine record of Lateglacial advances are discussed

A "Portrait" of Book XII of the Æneid: the Mosaic of the «House of the Medusa» (Alter do Chão, Portugal)

This paper addresses the study of a mosaic discovered in 2007 at the archaeological site of Alter do Chão, Portugal, whose central panel represents the penultimate scene narrated in the last Book of the Æneid – a Roman epic composed by the poet Publius Vergilius Maro (70 BC – AD 19), at the request of Gaius Julius Cæsar Octavianus Augustus (63 BC – AD 14): it shows the very moment when Turnus, the Latin king of the Rutuli, kneels before Æneas, considered the precursor to the foundation of Rome (Virgil, Æneid, XII, 926-950).

Granivorous birds as potentially important post-dispersal seed predators in a Brazilian forest fragment

In tropical forests, rodents exert a prominent role as post-dispersal seed predators, while other vertebrates apparently have a minor effect on seed predation. In some forest fragments in southeast Brazil, however, the density of rodents is unusually low, whereas terrestrial granivorous birds are abundant. In this study, we used seeds of a second-growth tree (Croton priscus, Euphorbiaceae) to investigate experimentally the relative importance of rodents and birds as seed predators in a forest fragment. We also estimated the density of terrestrial granivorous birds and trapped small mammals. Results indicate that, as a consequence of decreased rodent population and increased bird abundance, the latter are at least as important as the former as the main post-dispersal seed predators of C priscus. We interpret such apparent imbalance in the interaction between C priscus and their seed predators as a possible consequence of forest fragmentation.

A comunidade de tubarões (Chondrichthyes : selachii : Galea) da formação pirabas, Neógeno da Amazônia Oriental

A comunidade de tubarões (Selachii:Galea) proveniente da Formação Pirabas pode ser considerada como uma das mais representativas e de maior diversidade entre as unidades do Neógeno da América do Sul. A presença de 8 gêneros permitiu elaborar hipóteses sobre a reconstrução da cadeia trófica envolvendo outros elementos da paleofauna de vertebrados, assim como também serviu como um indicador paleoecológico adicional que corrobora dados anteriores sobre a reconstituição dos parâmetros paleoambientais da unidade geológica. Foi realizado uma revisão taxonômica das espécies previamente conhecidos para a Formação Pirabas, cuja composição da paleocomun idade de tubarões foi a seguinte: Carcharhinus spl Carcharhinus sp2, Carcharhinus sp3, Carcharhinus priscus, Sphyma magna, Hemipristis serra, Carcharodon megalodon, Isurus sp, Ginglyrnostoma serra, Ginglymostoma obliquum. Novas coletas possibilitaram a expansão de 31 exemplares depositados em museus brasileiros para 231 novos indivíduos, incluindo material microscópico. Esta coleta serviu para aumentar o conhecimento sobre a diversidade e aspectos paleoecológicos dos grupos representados.

A intersemiose texto-história-cinema na minissérie ROMA da HBO

From August 2005 to March 2007, the two seasons (with 12 and 10 episodes respectively) of the award winning miniseries HBO‟s ROME were aired by the Home Box Office (HBO) channel. With screenplay signed by various writers and directors, the TV series was a coproduction of HBO (USA) and BBC (UK) with support from RAI (Italy), and the show was filmed in multiple locations, but mainly in Cinecittà Film Studios in Rome, very famous for having been headquarters also for Federico Fellini‟s movies. In the first season, the miniseries depicts the conquest of Gaul, made by the military genius of Gaius Julius Caesar, and the political trajectory that made him accumulate power to such an extent that this divided Roman citizens into two factions, one supporting and the other opposing him, the latter focused mainly on the historic figure of General Gnaeus Pompey Magnus. The second season shows the period of civil war following the assassination of Caesar, and the future rise to power of his nephew, adopted son and sole heir, Gaius Octavian Augustus, who was destined to overcome his rivals as well as their allies in the triumvirate that had been formed to pursue and punish Caesar‟s assassins. These facts are well known and usually crowd the mind and imagination of every minimally educated person. The HBO series broke new ground not only for the talent of its writers, directors and actors, not only for its visual effects and locations nor for the vibrancy and grandeur of historical scenes – after all, “historical movies” in general do the same – but it has done so also by the (re)construction of historical events from the perspective of a pair of protagonists of whom too little is known: the centurions Titus Pullo and Lucius Vorenus, who are the only low-rank soldiers mentioned by Caesar in his book Commentaries on the Gallic War (Commentarii de Bello Gallico V.44). Thus, the fictionalization of events also took into account several Roman civilization data which were scattered through historical sources and also those that belong to the modern knowledge of material culture, resulting in a TV series whose filmic aesthetics has rare beauty and creativity. From the survey of textual, historical and cultural data put together in this film, as well as the distance featuring the creative space in the dimension of the gap between them, this paper aims to highlight two pivotal moments of visual and narrative strategies of the show: the opening credits footage and the final scenes of the first season of HBO's Rome.

Anatomy, phylogeny, and palaeoecology of the basal thalattosuchians (Mesoeucrocodylia) from the Liassic of Central Europe

In the marine Jurassic deposits of Europe, a group of marine crocodilians, the Thalattosuchia, belongs to the frequently found reptiles. Thalattosuchia are widely spread in Central Europe from the Jurassic to Lower Cretaceous, and some taxa are also distributed worldwide. The task of the work was to examine all taxa known from the Liassic of Europe. The most frequently known taxa Steneosaurus bollensis and Pelagosaurus typus are anatomically revised. New discoveries at the skull of Pelagosaurus typus e.g., the fact of a partly paired frontal are described by means of computed tomography investigations. In addition, juvenile specimens of this taxon are studied in detail for the first time. The rarely occurring taxon Platysuchus multiscrobiculatus is anatomically described in detail for the first time. It shows both in the skull and in the postcranial material morphological differences to Steneosaurus bollensis and Pelagosaurus typus. Thus Pl. multiscrobiculatus possesses, e.g., an ilium with a deeper acetabulum and a femur with a distinctly flexed femoral head. A juvenile specimen of Pl. multiscrobiculatus is now discovered and is described in parts for the first time, too. Furthermore, Steneosaurus gracilirostris and Steneosaurus brevior known from Lower Jurassic deposits of England are examined and in parts revised. In this work, Steneosaurs brevior is discovered with one specimen from the Upper Liassic of Holzmaden, Germany for the first time, and provides new evidence for the palaeobiogeographical distribution of the taxon. Because of the high number of investigated specimens, it is possible to study ontogenetic development from juvenile to adult stage in Steneosaurus bollensis, Pelagosaurus typus, and Platysuchus multiscrobiculatus. Biometric data are collected from thalattosuchians and extant crocodilians (e.g. Gavialis gangeticus) to investigate intraspecific variation, ontogenetic development, and taxa differentiation. The skulls of Platysuchus multiscrobiculatus and Steneosaurus bollensis are reconstructed three-dimensionally as wax models. The skull reconstructions form the basis of the jaw muscle restoration of Steneosaurus bollensis in connection with comparative studies at extant crocodilians. By means of functional morphologic analysis of the jaw musculature, the dentition, and the locomotor system of S. bollensis, possible conclusions are drawn for the prey options and the hunting behaviour. To clarify the relationships within the Thalattosuchia, a computer-based cladistic phylogenetic in-group analyse of 25 Thalattosuchia taxa is performed. For the analysis, following Thalattosuchia taxa are studied likewise at original material for comparisons: Metriorhynchus superciliosus, Metriorhynchus hastifer, Metriorhynchus leedsi, Geosaurus gracilis, Geosaurus giganteus, Teleidosaurus calvadosi, Teleidosaurus gaudryi, Teleosaurus cadomensis, Teleosaurus geoffroyi, Steneosaurus priscus, Steneosaurus edwardsi, Steneosaurus heberti, Steneosaurus leedsi, Steneosaurus boutilieri, Steneosaurus megarhinus, Steneosaurus obtusidens, and Machimosaurus hugii. The phylogenetic in-group analyse based on 115 characters, reveals a sister-group relationship of the monophyletic Teleosauridae and monophyletic Metriorhynchidae. Within the groups, some taxa are probably paraphyletic. The taxon Pelagosaurus typus is nested inside the Teleosauridae and not outside or within the Metriorhynchidae, as many authors suggested it so far. Based on these results, a tentative palaeobiogeographical-evolutionary scenario is developed.
