A forma no edifício residencial vertical em Natal : 1969 a 2000 :

This essay focuses on issues related to internal problems of the architecture discipline, specially those related to the aesthetics of the buildings. The universe analyzed in this research is constituted of some of the vertical housing built in Natal from the period of 1969 to 2000. As we could observe there are many different aspects in these apartment buildings external appearance, denoting increasing preoccupations in their formal elaboration in the battlefield for diversity against monotony of the simple prismatic volumetric forms.

Sanitarismo e planejamento urbano: a trajetória das propostas urbanísticas para Natal entre 1935 e 1969

The Escritório Saturnino de Brito (Saturnino de Brito Office), created in 1920 under the sanitaristic guidance of the engineer Saturnino de Brito, has a vast record of works throughout the whole national territory, even after the death of its founder, in 1929 at which point his son, and also engineer, Saturnino de Brito Filho, assumed the head of the company , with a compromise to continue his father s work and assure his administrative, technical and urbanistic principles up until the early 1980s, when that institution came to an end. The scarcity of theorical studies about this Office, alongside the importance of the contributions it made in countless cities, oriented the focus of this study on its performance in Natal, where it remained from 1935 to 1969, designing, executing and managing sanitationist works and the services associated with them and going through several political, economical, social, cultural and urbanistic contexts periodicized in this work into three moments. Thus, it is intended to analyze how the Saturnino de Brito Office behaved and adapted itself to the conjunctural changes that unfolded into each of these moments, and more specifically, to observe the forms of intervention adopted the principles, the instruments and the scope aiming to verify the transition of the sanitaristic set of urbanistic ideas into the urban planning as a development strategy on a local level

Consequências da colectomia associada à hepatectomia no metabolismo hepático e na forma e função de hemácias em ratos

This study investigated the influence of partial colectomy associated with hepatectomy on the biodistribution of the 99mTc-phytate, on metabolic parameters, as well as labeling and morphology of red blood cells. Wistar rats were distributed into three groups (each with 6), nominated as colectomy, colectomy+hepatectomy and sham. In the 30th postoperative day all rats were injected with 99mTc-phytate 0.1mL i.v. (radioactivity 0.66 MBq). After 15 minutes, liver sample was harvested and weighed. Percentage radioactivity per gram of tissue (%ATI/g) was determined using an automatic gamma-counter. Serum AST, ALT, alkaline phosphatase and red blood cells labeling were determined. The liver %ATI/g and red blood cells labeling were lower in colectomy and colectomy+hepatectomy rats than in sham rats (p <0.05), and no difference was detected comparing the colectomy and colectomy+hepatectomy groups. Red blood cells morphology did not differ among groups. Serum levels of AST, ALT and alkaline fosfatase were significantly higher in colectomy+hepatectomy than in colectomy rats (p<0.001). Hepatectomy associated with colectomy lowered the uptake of radiopharmaceutical in liver and in red blood cells in rats, coinciding with changes in liver enzymatic activity

Contribuição à citogenética de testudines e análise de assimetria flutuante em Eretmochelys imbricata, Cheloniidae

This work has contributed to knowledge of the order Testudines from cytogenetic and morphological point of view. With regard to the aspects proposed cytogenetic characterization of the species Mesoclemmys tuberculata (n = 5), endemic to the Caatinga biomes, through conventional techniques of cytogenetics and molecular levels. This species presented 2n = 58, NF = 64, the first submetacentric pair, the second metacentric and third subtelocentric, and the other microchromosome telocentric. This species showed a nucleolar bearing pair, coincident with the 18S ribosomal rDNA and that proved to be heterochromatic. Small heterochromatic blocks were also found in the centromeres of the largest chromosomes, as well as terminal regions in most other chromosomes of the complement, that were GC +. Telomeric sequences showed variable patterns of signal intensity, with some repeats more intense in microchromosomes and subtly in the larger ones. When compared with other species of the genus, the G-banding patterns showed a marked similarity between them. The first karyotypic description of the species will aid in future studies and the understanding of evolutionary aspects of this family. From the morphological point of view, we carried out studies of fluctuating asymmetry in sea turtle Eretmochelys imbricata, using methods of benchmarking between hatchlings and adults and their implications for natural selection. Data were collected at two different times: first during the spawning female and the second during the outbreak and birth of the nest. The analyzed characteristics consisted of measurements of length and width of front and rear flippers (CANT, LANT, CPOS and LPOS) also collected data on the number of hull plates, side plates (NPL), the surrounding plates (NPCIRC), and plastron; plates power plants (NPP), inframarginais plates (NPIM). With the values of asymmetry we calculated the value of strict heritability for these traits, the calculation was based on only one parent. A nonparametric analysis Mann-Whitneywas performed to compare the groups (females X hatchlings, newborn hatchlings X dead hatchlings). Adult females showed no bilateral fluctuating asymmetry (FA = 0) on the number plates of the hull and plastron, while offspring, living and dead, showed a greater level of variation in these meristic parameters. In the analysis of females x hatchlings we found a significant difference between the levels of asymmetry in hoof plates (p=0.006) an the width of hindlimbs (p=0.001). Levels of FA suggest an accurate indicator as to the viability or maintenance of the individual to the reproductive phase. The coefficient of heritability (h2) of FA , obtained from the regression analysis, showed that both have low and not statistically significant values(p> 0.1). In the case of exclusion of the effective role of genetics in the generation of FA, reproductive strategies based on high number of subsidiaries products, such as those observed in E. imbricata seems to implicate the production of individuals with high level of developmental instability

O esgotamento sanitário e o uso do território em Natal/RN (1969 - 2009)

Natal é uma cidade bastante antiga, data desde o ano de 1599. Durante seus três primeiros séculos de existência ela praticamente não cresceu, porém teve um significativo aumento populacional e crescimento urbano na década de 1940, a partir da Segunda Guerra Mundial. Nos últimos anos, Natal tem passado por um intenso processo de urbanização, que exigiu da cidade um acompanhamento na sua infraestrutura, principalmente por ser uma cidade turística; o que aumenta bastante a sua demanda. O esgotamento sanitário entra como um dos problemas que Natal tem que resolver. A cidade possui apenas cerca de 32% do seu território servido por um sistema de coleta de esgotos. O serviço de esgotamento sanitário é de extrema importância para a manutenção da saúde e da qualidade de vida da população, assim como os demais serviços que compõem o saneamento básico. Tal serviço tem sido um grande desafio para a população e para os administradores públicos. Este trabalho tem como principal objetivo analisar os impactos socioespaciais causados pelas diferentes formas de esgotamento sanitário existentes em Natal. Durante a elaboração deste trabalho, foram realizadas pesquisas bibliográfica e de campo através de estudos documentais, visitas aos órgãos públicos, entrevistas, aplicação de formulários junto à população e observação direta. O embasamento teórico parte dos estudos de Milton Santos sobre território usado, adotando também, ao longo do desenvolvimento do trabalho, as contribuições de outros autores. O território usado foi escolhido como categoria de análise deste trabalho, por entendermos que as questões do esgotamento sanitário passam pelo uso do território, e este se dá pela sociedade como um todo
