Towards a demand model for maritime passenger transportation in the Caribbean: a regional study of passenger ferry services

In this paper, the main factors that influence the demand for maritime passenger transportation in the Caribbean were studied. While maritime studies in the Caribbean have focused on infrastructural and operational systems for intensifying trade and movement of goods, there is little information on the movement of persons within the region and its potential to encourage further integration and sustainable development. Data to inform studies and policies in this area are particularly difficult to source. For this study, an unbalanced data set for the 2000-2014 period in 15 destinations with a focus on departing ferry passengers was compiled. Further a demand equation for maritime passenger transportation in the Caribbean using panel data methods was estimated. The results showed that this demand is related to the real fare of the service, international economic activity and the number of passengers arriving in the country by air.

Methylation status of ANAPC1, CDKN2A and TP53 promoter genes in individuals with gastric cancer

Gastric cancer is the forth most frequent malignancy and the second most common cause of cancer death worldwide. DNA methylation is the most studied epigenetic alteration, occurring through a methyl radical addition to the cytosine base adjacent to guanine. Many tumor genes are inactivated by DNA methylation in gastric cancer. We evaluated the DNA methylation status of ANAPC1, CDKN2A and TP53 by methylation-specific PCR in 20 diffuse- and 26 intestinal-type gastric cancer samples and 20 normal gastric mucosa in individuals from Northern Brazil. All gastric cancer samples were advanced stage adenocarcinomas. Gastric samples were surgically obtained at the João de Barros Barreto University Hospital, State of Pará, and were stored at -80°C before DNA extraction. Patients had never been submitted to chemotherapy or radiotherapy, nor did they have any other diagnosed cancer. None of the gastric cancer samples presented methylated DNA sequences for ANAPC1 and TP53. CDKN2A methylation was not detected in any normal gastric mucosa; however, the CDKN2A promoter was methylated in 30.4% of gastric cancer samples, with 35% methylation in diffuse-type and 26.9% in intestinal-type cancers. CDKN2A methylation was associated with the carcinogenesis process for ~30% diffuse-type and intestinal-type compared to non-neoplastic samples. Thus, ANAPC1 and TP53 methylation was probably not implicated in gastric carcinogenesis in our samples. CDKN2A can be implicated in the carcinogenesis process of only a subset of gastric neoplasias.

Revisão do gênero Neoxyphinus Birabén 1953 (Araneae, Oonopidae)

The Neotropical genus Neoxyphinus Birabén 1953 is revised, comprising nine species found from Venezuela to northern Argentina. The monotypic genus Decuana Dumitrescu and Georgescu 1987 is synonymized with Neoxyphinus and its type species, D. hyspida Dumitrescu and Georgescu 1987, is transferred to this genera. Confirming suspicions rose in literature, Dysderina termitophila Bristowe 1938 is transferred to Neoxyphinus and recognized as senior synonym of N. ogloblini Birabén 1953. Six new species are described, all of which known from both sexes: N. petrogoblin, from Amazonas, Brazil and Huanuco, Peru; N. gregoblin, from Andres Bello, Venezuela; N. axe, from Bahia, Brazil; N. barreirosi, from north Brazil; N. brega, from Brazil, Colombia, Guyana and Venezuela and N. caterete, from São Paulo, Brazil.

Epigenetic alterations in human brain tumors in a Brazilian population

Aberrant methylation of CpG islands located in promoter regions represents one of the major mechanisms for silencing cancer-related genes in tumor cells. We determined the frequency of aberrant CpG island methylation for several tumor-associated genes: DAPK, MGMT, p14^ARF, p16^INK4a, TP73, RB1 and TIMP-3 in 55 brain tumors, consisting of 26 neuroepithelial tumors, 6 peripheral nerve tumors, 13 meningeal tumors and 10 metastatic brain tumors. Aberrant methylation of at least one of the seven genes studied was detected in 83.6% of the cases. The frequencies of aberrant methylation were: 40% for p14^ARF, 38.2% for MGMT, 30.9% for, p16^INK4a, 14.6% for TP73 and for TIMP-3, 12.7% for DAPK and 1.8% for RB1. These data suggest that the hypermethylation observed in the genes p14^ARF, MGMT and p16^INK4a is a very important event in the formation or progression of brain tumors, since the inactivation of these genes directly interferes with the cell cycle or DNA repair. The altered methylation rate of the other genes has already been reported to be related to tumorigenesis, but the low methylation rate of RB1 found in tumors in our sample is different from that so far reported in the literature, suggesting that perhaps hypermethylation of the promoter is not the main event in the inactivation of this gene. Our results suggest that hypermethylation of the promoter region is a very common event in nervous system tumors.

Estudo da variação da porcentagem e da estimativa de geração de gás metano para o aterro sanitário do município de Rio Claro - SP

Increased demand for energy and the search for alternative energy sources are remarkable and current facts. The management of domestic solid waste is also part of the issue in view of the possibility of power generation in existing landfills, which could provide financial autonomy to the system of waste management and improve the environmental balance of landfills in Brazil, currently only used for final solids disposal. Landfill gas is a viable alternative energy source has been tested in landfills in the World and in Brazil. Thus, the research aimed to evaluate the percentage of methane (CH4) present in three sinks of gases from a landfill in the municipality of Rio Claro – SP (Brazil), and to estimate the potential methane generation over its life through the application of a mathematical model. As a result it was found that in general the percentage of methane present in the gases is significant, between 50 and 62%. It was also noted that waste with disposal time between 8 and 12 months already are in the methanogenic stage. Finally, there was a tendency to increase the generation of methane in the transition periods of rain and drought

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.
