Gades and the Mediterranean: a Process of Integration

The impetus for this paper is to present possible contributions of the Network Theory approach to the analysis of the Roman presence in Turdetania by the end of the 1st millennium BC. Firstly, we discuss how some written sources, such as Strabo’s Geography, describe this region and how the countryside and coastal areas are mentioned. Secondly, we present how contemporary historiography makes use of Network Theory to investigate numerous issues of Ancient History. Finally, we point out a proposal for Social Network Analysis (SNA) to questions regarding Turdetania before and after Roman occupation

EVASÃO NA EDUCAÇÃO SUPERIOR: UM ESTUDO PRELIMINAR NA UFRB

A evasão no Ensino Superior tem sido tema de discussões no meio acadêmico nos últimos anos, por se apresentar como um fenômeno de muitos significados. Diante disso, o presente artigo integra uma investigação preliminar sobre o estudo da evasão na Universidade Federal do Recôncavo da Bahia, tendo como objetivo apresentar os resultados de uma pesquisa sobre os motivos da evasão nesta universidade na qual são identificados como sujeitos os ingressantes nos cursos de graduação do período letivo de 2011.1. Para a realização do referido estudo, procedeu-se a utilização de uma abordagem metodológica de natureza quantitativa e qualitativa, sendo utilizado enquanto instrumento para coleta de dados a análise documental; a aplicação de questionários e a realização de entrevistas a coordenadores de cursos de graduação da instituição. Os resultados preliminares apontam a necessidade de maiores observações acerca do fenômeno da evasão no Ensino Superior, mediante a ampliação de aspectos a serem analisados, tais como os aspectos econômicos dos sujeitos pesquisados, assim como sinalizam também a importância do desenvolvimento de ações que garantam a permanência dos estudantes, visando diminuir as chances de evasão

Intelligent Systems as Tools for Measuring Residential Energy Consumption

The implementation of intelligent systems in homes for measuring energy consumption are possibilities that owe their viability to the IoT (Internet of Things and investments in R&D). Becoming fundamental for this change in the way of thinking and using electric power in households, buildings and especially in industry 4.0. The present work demonstrates an experiment focused on a residence for the analysis of energy consumption measurement, with the use of a nano arduino plate, current and voltage sensors, internet connection and use of the MQTT protocol making the integration in the Blynk platform. Obtaining as results voltage approximately 224V, electric current close to 3.89A, 356 points of samples for measurement of consumption and 255 points for preparation of graphs. Minimums for voltage and current 207.75V and 0.62A respectively and maximums 233.22V and 25.31A. A standard deviation of 5.54 for voltage and 3.33 for current. Analyses performed by Blynk, from estimates by mathematical modeling, considered by means of tests and it was observed that the behavior of current and voltage signals are close to the realities of energy distributors

Luttinger liquid superlattices: realization of gapless insulating phases

We investigate Luttinger Liquid superlattices, a periodic structure composed of two kinds of one-dimensional systems of interacting electrons. We calculate several properties of the low-energy sector: the effective charge and spin velocities, the compressibility, various correlation functions, the Landauer conductance and the Drude weight. The low-energy properties are subsumed into effective parameters, much like homogeneous one-dimensional systems. A generic result is the weighted average nature of these parameters, in proportion to the spatial extent of the underlying subunits, pointing to the possibility of ``engineered'' structures. As a specific realization, we consider a one-dimensional Hubbard superlattice, which consists of a periodic arrangement of two long Hubbard chains with different coupling constants and different hopping amplitudes. This system exhibits a rich phase diagram with several phases, both metallic and insulating. We have found that gapless insulating phases are present over a wide range of parameters.Comment: 16 pages, 15 figures, RevTeX

Genetic susceptibility to thyroid cancer: contributions of RET polymorphisms

Thyroid cancer is the most common malignancy of the endocrine system, represents more than 1% of all malignancies and has an estimated annual incidence of 212,000 cases worldwide. The term differentiated thyroid carcinoma (DTC) comprises the subtypes papillary thyroid carcinoma (PTC) and follicular thyroid carcinomas (FTC), these subtypes represent the two most common subtypes of thyroid cancer (approximately 80% and 10% respectively). Despite its incidence DTCs have a good prognosis with relatively few metastases and deaths associated. The polymorphisms (variants in DNA sequence among individuals that have a frequency of at least 1% in a population) of RET proto-oncogene have been studied in different populations for association with susceptibility to thyroid cancer, but with inconsistent findings mainly in DTC. To clarify the contribution of single locus or haplotypes (polymorphisms that are transmitted through generations as a unit) of RET polymorphisms to genetic susceptibility to DTC among Portuguese patients, we conducted a case–control study by analyzing four well-characterized RET polymorphisms (G691S, L769L, S836S and S904S). To achieve this aim, the RET polymorphisms were genotyped and haplotype frequencies were estimated in a population of 282 individuals with DTC and in a control population of 254 individuals. Allele, genotype and haplotype distributions were compared among cases and controls. Patient population was subdivided according to several clinical parameters and allele, genotype and haplotype distributions were compared among the subgroups. The single locus analysis showed an overrepresentation of the S836S polymorphism in patients when compared to controls. Also the heterozygous genotypes of the G691S/S904S polymorphisms were overrepresented in cases diagnosed after the age of 45 years and the heterozygous genotype of G691S polymorphism revealed an overrepresentation in patients with tumors larger then 10mm of diameter at diagnosis. The haplotype analysis showed an overrepresentation of GGTC haplotype in patients particularly in those diagnosed after the age of 45 years. In conclusion, our data suggest that the S836S polymorphism may be associated with increased risk of DTC. Also the heterozygous genotype of the G691S/S904S polymorphisms seems to be associated with age of onset of DTC and additionally the heterozygous genotype of G691S polymorphism appeared to be in association with tumor size. Finally, one haplotype appears to be associated with increased risk of DTC particularly in those developed in later age (after the age of 45 years). These findings need to be confirmed by larger studies in order re-evaluate the role of these variants in the susceptibility to DTC.Thyroid cancer is the most common malignancy of the endocrine system, represents more than 1% of all malignancies and has an estimated annual incidence of 212,000 cases worldwide.
