Natal, outra cidade : o papel da Intendência Municipal no desenvolvimento de uma nova ordem urbana(1904-1929)

The present work regards, as its subject, the management of the urban space. It aims to survey the role assumed by the Conselho de Intendência Municipal de Natal (Municipal Stewardship Council of Natal) in the formation of a new urban order between the years of 1904 and 1929. For a better comprehension of the object of research, the milestone of the time span analyzed in this work was receded to the year of 1890, specifically at the first chapter of this dissertation. In this chapter, we will turn our attention towards an analysis of the referred council, on the regulation of its operation, the relations of this institution with the state government and its mechanisms of action in the city, among other topics. In the next chapter, we will delve into an elite who administrated the city of Natal during the first republic, understanding that the analysis of the formation of a modern city project by the Municipal Stewardship undergoes the comprehension of those who leaded this institution. In the third chapter, we will examine the limits of the municipal management to put into practice its projects to the upraise of a new Natal, between the years of 1904 and 1921. The last chapter, on its turn, presents a new Stewardship, reformulated after a process of administrative streamlining, and a city that transforms itself, especially during the O Grady tenure by receiving major constructions, which alter its main features. We will regard, as the main resources of this study, articles from the daily newspapers A República (The Republic) and Diário de Natal (Daily Natal), dictums, announcements, laws, state decrees and the messages disclosed by the state government. To build a way of analysis, we make use of authors such as Anthony Giddens, Peter Burke and Laurent Vidal, among many others who discuss concepts related to the proposed theme

Por uma "cidade nova": apropriação e uso do solo urbano no terceiro bairro de Natal (1901-1929)

This research aimed to analyze the forms of ownership and use of urban land in Cidade Nova, third official neighborhood of Natal (Rio Grande do Norte), between 1901 and 1929. During this period, the city and state authorities began an urban renewal, trying to transform the city, represent it as a new, modernized, able to track the progress and the new political condition of the capital of a republican state. It is observed in Cidade Nova construction of a new material and symbolic territory: the area that was once occupied by huts built by refugees of drought and some summer houses, was, from 1901, transformed, scanned through a urban plan. In Natal various municipal resolutions published between 1901-1929, showed the desires of the group leader to build on Cidade Nova neighborhood a delightful, modernized its structures to reflect the new political condition of the capital of a republican state. The analyzes of the edicts of the materials published in the newspapers A Republica and Diário do Natal, and especially the study of letters of aforamento, demonstrated how many laws were not enforced or resignified, highlighting the existing continuities. Thus, throughout the paper aims to examine how this territory was occupied and used by its inhabitants, such as the granting of land in aforamento may exemplify this practice and noncompliance and how the land was used to consolidate relations of influence and power. After all, the values given to a space, turning it into territory, resulting from the social dimension of this space, in other words, the social categories that use it. Cannot be, therefore, analyze the ways of appropriation and use of urban land in the third neighborhood of Natal without studying individuals who appropriated and used this territory. The study of the allocation of extant aforamentos of land located in this neighborhood process demonstrated the formation of a specific type of market that were at stake not only economic exchanges, but also, and above all symbolic exchanges involving political and social capital. The analysis of such personnel developed market with the lands of Cidade Nova may indicate the existing relations of power between state government, Stewardship and tenants, providing a significant example of this modernization Natal early twentieth century process, guided by a more wealthy group and influential and characterized by limited social changes

Social and financial aspects of the artisanal fisheries of Middle Sao Francisco River, Minas Gerais, Brazil

The presence or absence of motorized boats, partnerships and multispecies catches characterize the fisheries of Sao Francisco River, Minas Gerais, Brazil. Fishing activity based on 109 interviews, carried out in the wet (high water: February and March) and dry (low water: July and August) seasons, with professional fishermen are described. Aiming to identify the fishery income components, a covariance model was proposed, with the income as the response variable, related to the factors: fishing ground, use of motorized or paddle boat; seasonality; presence of fishing assistant, and the following covariates: capture in weight in the week Frier to the interview, fisherman experience in yrs; and distance (km) travelled for fishing. The results indicated that the main contributions to income were the absence of an engine (because of high price of the fuel), the absence of a partner (because of low capture) and the amount of fish caught by the fishermen.

Resources Taken to the Nest by Protopolybia exigua (Hymenoptera, Vespidae) in Different Phases of the Colony Cycle, in a Region of the Medio Sao Francisco River, Bahia, Brazil

The present study aimed to identify what resources were taken to the nest by workers of Protopolybia exigua (de Saussure), to verify if there is a relationship between physical factors of weather and phases of colony development and the collection of different resources and also to observe if the wasps carry macerated prey in the crop. The species collected nectar (62.8%), wood pulp for nest building (6.1%), water(2.9%), prey (0.8%) and resin (0.2%). Moreover, workers of P exigua do carry macerated prey in the crop. There was a positive correlation (r = 0.85, p = 0.0004) between the presence of larvae in the nest and the carrying of solid contents in the crop, which provides strong evidence that this species macerates its prey while still in the field, before taking it to the nest. There was positive influence of the temperature on the collection of nectar (r = 0.89, p = 0.0001) and water (r = 0.46, p = 0.0066) and negative influence of relative air humidity on the collection of the same resources (r = - 0.88, p = 0.0001 and r = - 0.37, p = 0.0160, respectively). Luminosity influenced the gathering of water (r = 0.43, p = 0.0089) and Pulp for nest building (r = 0.31, p = 0.0274) and the wind speed did nor influence the collection of any resources. Nectar is the main item taken to the nest during all phases of the colony.

Amino Acids on Mango Yield and Fruit Quality at Submedio Sao Francisco Region, Brazil

Farmers of the Submedio Sao Francisco Region (Brazil) have been spraying amino acids on mango trees with the objective of increasing panicle length and improving fruit retention and quality. This study, done in two experiments, tested the effect of amino acids sprayings at concentrations of 0.0%; 0.02%; 0.04% and 0.06%, on mango plants, 'Tommy Atkins', on the budding phase (panicles with 5 cm), fruit set and fruit growth (5 cm diameter). They were carried out from June to October in 2003, that is the natural period for harvest in the region, and from January to May, in 2004. There were no statistical differences in the first experiment among treatments regarding panicle length and fruit production, probably due to an appropriate management of nutrition, water and plant growth regulators, besides climatic conditions, mainly temperature and solar radiation. In the second experiment, significant increments in the panicle length of 13.37%, 11.70% and 21.4% were observed with amino acids concentrations, compared to the control. Increasing amino acids doses also enhanced the number of fruits per plant, thirty days before the harvest, in 16.17%, 45.32% and 37.38%, respectively, compared to the control, but there were no significant statistical differences. Characteristics of fruit quality during storage, as weight loss, total soluble solids, total titratable acidity and pulp firmness were not significantly affected by amino acids spraying. Changes on those variables were registered as a consequence of fruit ripening. Amino acids sprays lightly delayed the evolution of skin luminosity and Hue of pulp, but the differences could not be visually identified. The concentrations of amino acids were not efficient for improving the natural concentrations of these substances in the leaves, which could be the reason for the non significant effects on the variables analyzed.

Adubação organomineral e biofertilização líquida na produção de frutos de pinheira ( Annona squamosa L.) no submédio São Francisco, Brasil

The organic production systems based on natural processes do not allow the use of synthetic fertilizers with a high solubility, so it is required the use of technologies in accordance with the organic production legislation in order to make the technical, economical and environmental sustainable activities viable. To evaluate the effects of the usage of mineral and organic natural fertilizers, associated with liquid biofertilizers (BLE= enriched liquid biofertilizer and BF= leaf biofertilizers) on the production of the sugar apple fruit crop Annona squamosa L., replacing totally the chemical fertilizers, used by conventional farming systems, a nine year old orchard was driven in the irrigated plot n degrees 1295, irrigated project Nilo Coelho, district of Petrolina - PE. The experiment was carried out from September 2005 to February 2006. The experimental design was done through randomized blocks with eight treatments and four replications in plots of three plants each, with 96 plants in total. The treatments were the following: T(1) - plants with no fertilizer; T(2) - 60 g de N + 32 g de P(2)O(5) + 48 g de K(2)O; T(3) - 90g de N + 32 g de P(2)O(5) + 48 g de K(2)O; T(4) - 30 g de N + 32 g de P(2)O(5) + 48 g de K(2)O + 15 L de BLE + BF a 5 %; T(5) - 60g de N + 32 g de P(2)O(5) + 48 g de K(2)O + 30 L de BLE + BF a 5 %; T(6)- 90g de N + 32 g de P(2)O(5) + 48 g de K(2)O + 45 L de BLE + BF a 5 %; T(7) - 120g de N + 32 g de P(2)O(5) + 48 g de K(2)O + 60 L de BLE + BF a 5 %; T(8) - 150 g de N + 32 g de P(2)O(5) + 48 g de K(2)O + 75 L de BLE + BF a 5 % The fruit growth analyses (diameter and average length), total yield, productivity, average fruit weight, average number of fruits, fresh weight of the skin and pulp and dry weight of the fruits were used to evaluate the experiment. The results were relevant to the total production, fresh weight of the skin and dry weight of the fruits. The use of organominerals associated with liquid fertilizers increased significantly the productivity in values ranging from 10.44% (T(5) = 1.98 t ha(-1)) to 24.52 % (T(7) = 12.34 %). The treatment T(3) stood out (90g de N + 32g de P(2)O(5) + 48g de K(2)O) with a higher production than the control. The fruit weight increased in the fertilized treatments, with values increasing from treatment (T(2) = 5.26 %) to the treatment (T(7) = 12.34 %) in relation to the control. The fruit development was characterized by an average growth increase of 82 % in length and 84 % in diameter until the 56(th) day, with a sigmoidal growth pattern.

Avaliação de seis variedades de uvas sem sementes no Submédio São Francisco

This work aimed to study aspects related to vegetative and productive development of plants and characteristics and chemical components of bunches of six seedless grape varieties at environmental conditions of São Francisco river's valley, Northeastern Brazil. The experiment was carried out during 1997 and 1998. The varieties tested were grafted on IAC 572 ('Jales') rootstock. The experimental model utilized was totally randomized, and with parcels subdivided into different production cycles. The results showed significative differences among varieties at different pruning times. The average weight of bunches varied from 164.8 g for 'Marroo Seedless' and 203.5 g for 'Beauty Seedless'. The average diameter of berries was superior to 15.7 mm for all of the varieties. The total soluble solids varied from 14.05°Brix in 'Canner' to 19.6°Brix in 'Venus'. The total titratable acidity (ATT) was lower than 0.91 g tartaric acid/100 mL of juice. The ratio SST/ATT varied from 19.05 in 'Beauty Seedless' to 28.57 in 'Vênus'. 'Vênus' and 'Marroo Seedless' were the most productive varieties, with the average annual production of 24 ton/ha and 20 ton/ha, respectively.

Foraging activity of Protopolybia exigua (Hymenoptera, Vespidae) in different phases of the colony cycle, at an area in the region of the Médio São Francisco River, Bahia, Brazil

In this work, the foraging activity of Protopolybia exigua (de Saussure) was studied, aiming to verify the amplitude of the foraging time, the relation between the physical factors of weather (temperature, relative air humidity, luminosity and wind speed) and the daily activity of searching for resources, as well as to analyze the influence of the colony development phases and the number of individuals (adults and immatures) engaged in such activity. The study was carried out in two areas of the city of Bom Jesus da Lapa, Bahia, Brazil, during the period from January to June 2006, when the observation of 12 colonies of P. exigua was performed. The results revealed this species presented an amplitude of activity of almost 13 hours. There was an average of 44.4 nest exits and 37.6 returns a day by the nest workers and the Returns with Resources Index for this species was 93.5%. The foraging activity increased as of 10:01, and became more intense, with the peak from 1:01 p.m. to 4:00 p.m., when the highest temperatures (°C) and the lowest values of relative air humidity (%) were observed. The colonies that had a larger number of larvae presented a higher average number of trips to the field per hour (10.94) and the number of females in the colony tends to induce foraging activity. There were no differences between the numbers of nest exits by the workers regarding the three phases of colony development.
