Cooperativa habitacional autofinanciável :uma alternativa de mercado à escassez de financiamento

As an example of what happened in Brazil in the 90s, it s noticed in Natal a new system of cooperative housing production which is done by advancing the users resources selffinancing. This system comes as an alternative for the real state market performance since the end of the National Housing Bank (BNH), in 1986. Self-financed housing cooperatives play an important social role by contributing to own housing acquisition by low-income population, without, however, becoming a mechanism of social interest housing production. It is important to consider that Brazil registers a housing deficit of 6.6 million housing units (IBGE 2000/Census), which, compared to 1991, shows an increment of 21.7% to a growth rate of 2.2% a year. This deficit figure has been deepening, mainly with the end of the National Housing Bank (BNH). The self-financed cooperative housing production broadens around the Metropolitan Region of Natal (RMN) and remains as an alternative to the lack of financing in the housing / real state market. In general, the aim of this work is to analyze the role of self-financing housing cooperatives on the housing production in the RMN, in order to identify their role in the real state market, in the own housing promotion and in the housing policy. The Universe of this study is performance of four housing cooperatives - CHAF-RN, COOPHAB-RN, MULTHCOOP e CNH - that work through self-financing. It is considered here an amount of 38 undertakings launched between 1993 and 2002, including 8143 housing units. The methodology adopted consists of bibliographic, documental and field research. As a result, actions like brokerage, marketing, speculation, and the criteria to define places for undertakings and final products, show how close they are to the housing market production. As a matter of fact, this short distance explains why the self-financed cooperative production for social interest housing is still limited. This reinforces the theory that it is necessary to define and implement a subsidized housing policy to serve the low-income Brazilian population

Caracterização estrutural e avaliação das atividades farmacológicas da fucana B extraída da alga Dictyota menstrualis

Seaweeds are a major source of biologically active compounds . In the extracellular matrix of these organisms are sulfated polysaccharides that functions as structural components preventing it against dehydration. The fraction 0.9 (FucB) rich in sulfated fucans obtained from brown seaweed Dictyota menstrualis was chemical characterized and evaluated for pharmacological activity by testing anticoagulant activity, stimulatory action on the synthesis of an antithrombotic heparan sulfate, antioxidant activity and its effects in cell proliferation. The main components were FucB carbohydrates (49.80 ± 0.10 %) and sulfate (42.30 ± 0.015 %), with phenolic compounds ( 3.86 ± 0.016 %) and low protein contamination ( 0.58 ± 0.001 % ) . FucB showed polydisperse profile and analysis of signals in the infrared at 1262, 1074 and 930 cm -1 and 840 assigned to S = O bonds sulfate esters , CO bond presence of 3,6- anhydrogalactose , β -D- galactose non- sulfated sulfate and the axial position of fucose C4 , respectively. FucB exhibited moderate anticoagulant activity , the polysaccharides prolonged time (aPTT ) 200 ug ( > 90s ) partial thromboplastin FucB no effect on prothrombin time (PT), which corresponds to the extrinsic pathway of coagulation was observed. This stimulation promoted fraction of about 3.6 times the synthesis of heparan sulfate (HS) by endothelial cells of the rabbit aorta ( RAEC ) in culture compared with cells not treated with FucB . This has also been shown to compete for the binding site with heparin. The rich fraction sulfated fucans exhibited strong antioxidant activity assays on total antioxidant (109.7 and 89.5 % compared with BHT and ascorbic acid standards ) , reducing power ( 71 % compared to ascorbic acid ) and ferric chelation ( 71 , comparing with 5 % ascorbic acid). The fraction of algae showed cytostatic activity on the RAEC cells revealed that the increase of the synthesis of heparan sulfate is not related to proliferation. FucB showed antiproliferative action on cell lines modified as Hela and Hep G2 by MTT assay . These results suggest that FucB Dictyota menstrualis have anticoagulant , antithrombotic , antioxidant potential as well as a possible antitumor action, promoting the stimulation of the synthesis of antithrombotic HS by endothelial cells and is useful in the prevention of thrombosis, also due to its inhibitory action on species reactive oxygen ( ROS ) in some in vitro systems , being involved in promoting a hypercoagulable state

Otimização de vazão de poços injetores em projeto de injeção de água utilizando simulação por linhas de fluxo

Until the early 90s, the simulation of fluid flow in oil reservoir basically used the numerical technique of finite differences. Since then, there was a big development in simulation technology based on streamlines, so that nowadays it is being used in several cases and it can represent the physical mechanisms that influence the fluid flow, such as compressibility, capillarity and gravitational segregation. Streamline-based flow simulation is a tool that can help enough in waterflood project management, because it provides important information not available through traditional simulation of finite differences and shows, in a direct way, the influence between injector well and producer well. This work presents the application of a methodology published in literature for optimizing water injection projects in modeling of a Brazilian Potiguar Basin reservoir that has a large number of wells. This methodology considers changes of injection well rates over time, based on information available through streamline simulation. This methodology reduces injection rates in wells of lower efficiency and increases injection rates in more efficient wells. In the proposed model, the methodology was effective. The optimized alternatives presented higher oil recovery associated with a lower water injection volume. This shows better efficiency and, consequently, reduction in costs. Considering the wide use of the water injection in oil fields, the positive outcome of the modeling is important, because it shows a case study of increasing of oil recovery achieved simply through better distribution of water injection rates

Estudo comparativo da injeção de água usando poços verticais e horizontais

Oil recovery using waterflooding has been until now the worldwide most applied method, specially for light oil recovery, its success is mainly because of the low costs involved and the facilities of the injection process. The Toe- To-Heel Waterflooding TTHWTM method uses a well pattern of vertical injector wells completed at the bottom of the reservoir and horizontal producer wells completed at the top of it. The main producing mechanism is gravitational segregation in short distance. This method has been studied since the early 90´s and it had been applied in Canada with positive results for light heavy oils, nevertheless it hasn´t been used in Brazil yet. In order to verify the applicability of the process in Brazil, a simulation study for light oil was performed using Brazilian northwest reservoirs characteristics. The simulations were fulfilled using the STARS module of the Computer Modelling Group Software, used to perform improved oil recovery studies. The results obtained in this research showed that the TTHWTM well pattern presented a light improvement in terms of recovery factor when compared to the conventional 5- Spot pattern, however, it showed lower results in the economic evaluation

Pirólise térmica e catalítica de resíduos de vácuo gerados no refino de petróleo

In this study, was used a very promising technique called of pyrolysis, which can be used for obtaining products with higher added value. From oils and residues, since the contribution of heavier oils and residues has intensified to the world refining industry, due to the growing demand for fuel, for example, liquid hydrocarbons in the range of gasoline and diesel. The catalytic pyrolysis of vacuum residues was performed with the use of a mesoporous material belonging the M41S family, which was discovered in the early 90s by researchers Mobil Oil Corporation, allowing new perspectives in the field of catalysis. One of the most important members of this family is the MCM-41, which has a hexagonal arrangement of mesopores with pore diameters between 2 and 10 nm and a high specific surface area, making it very promising for use as a catalyst in petroleum refining for catalytic cracking, and their mesopores facilitate the access of large hydrocarbon molecules. The addition of aluminum in the structure of MCM-41 increases the acidity of the material, making it more positive for application in the petrochemical industry. The mesoporous material of the type Al-MCM41 (ratio Si / Al = 50) was synthesized by hydrothermal method starting from the silica gel, NaOH and distilled water added to the gel pseudobohemita synthesis. Driver was used as structural CTMABr. Removal of organic driver (CTMABr) was observed by TG / DTG and FTIR, but this material was characterized by XRD, which was observed the formation of the main peaks characteristic of mesoporous materials. The analysis of adsorption / desorption of nitrogen this material textural parameters were determined. The vacuum residues (VR's) that are products of the bottom of the vacuum distillation tower used in this study are different from oil fields (regions of Ceará and Rio de Janeiro). Previously characterized by various techniques such as FTIR, viscosity, density, SARA, elemental analysis and thermogravimetry, which was performed by thermal and catalytic degradation of vacuum residues. The effect of AlMCM-41 was satisfactory, since promoted a decrease in certain ranges of temperature required in the process of conversion of hydrocarbons, but also promoted a decrease in energy required in the process. Thus enabling lower costs related to energy expenditure from degradation during processing of the waste

O direito à saúde e a política nacional de atenção oncológica: uma análise a partir da crescente judicialização dos medicamentos antineoplásicos

The 1988 Federal Constitution of Brazil by presenting the catalog of fundamental rights and guarantees (Title II) provides expressly that such rights reach the social, economic and cultural rights (art. 6 of CF/88) as a means not only to ratify the civil and political rights, but also to make them effective and practical in the life of the Brazilian people, particularly in the prediction of immediate application of those rights and guarantees. In this sense, health goes through condition of universal right and duty of the State, which should be guaranteed by social and economic policies aimed at reducing the risk of disease and other hazards, in addition to ensuring universal and equal access to actions and services for its promotion, protection and recovery (Article 196 by CF/88). Achieving the purposes aimed by the constituent to the area of health is the great challenge that requires the Health System and its managers. To this end, several policies have been structured in an attempt to establish actions and services for the promotion, protection and rehabilitation of diseases and disorders to health. In the mid-90s, in order to meet the guidelines and principles established by the SUS, it was established the Política Nacional de Atenção Oncológica PNAO, in an attempt to sketch out a public policy that sought to achieve maximum efficiency and to be able to give answers integral to effective care for patients with cancer, with emphasis on prevention, early detection, diagnosis, treatment, rehabilitation and palliative care. However, many lawsuits have been proposed with applications for anticancer drugs. These actions have become very complex, both in the procedural aspects and in all material ones, especially due to the highcost drugs more requested these demands, as well as need to be buoyed by the scientific evidence of these drugs in relation to proposed treatments. The jurisprudence in this area, although the orientations as outlined by the Parliament of Supreme Court is still in the process of construction, this study is thus placed in the perspective of contributing to the effective and efficient adjudication in these actions, with focus on achieving the fundamental social rights. Given this scenario and using research explanatory literature and documents were examined 108 lawsuits pending in the Federal Court in Rio Grande do Norte, trying to identify the organs of the Judiciary behave in the face of lawsuits that seeking oncology drugs (or antineoplastic), seeking to reconcile the principles and constitutional laws and infra constitutional involving the theme in an attempt to contribute to a rationalization of this judicial practice. Finally, considering the Rational Use of health demands and the idea of belonging to the Brazilian people SUS, it is concluded that the judicial power requires ballast parameters of their decisions on evidence-based medicine, aligning these decisions housing constitutional principles that the right to health and the scientific conclusions of efficacy, effectiveness and efficiency in oncology drugs, when compared to the treatments offered by SUS

A Servidão Administrativa e o Estado Regulador: Compatibilidade com o Princípio Constitucional da Legalidade e a Limitação ao Direito Real de Propriedade

The economic changes occurred in the 90s, with the restructuring and privatization of various sectors of the economy have led to a redefinition of the State role, assuming a position of regulator and supervisor of public services in place to direct its role as straight intervenor. It is through the regulatory agencies, autarchies with special legal personality under public law, that the Regulator State will act. In this context, the first objective of this research is to analyze the legality of easements imposed by entities of the Direct Administration and Regulatory Agencies, whose execution is delegated to legal persons of private law, being those public service companies or mixed-economy societies. This examination in question the limits of servitude as a restrictive institute of property rights, observing the principles of function, supremacy of the public interests over the private ones, legality and the separation of powers. Defend the property rights like a fundamental right and your insurance as determining factor of economic development and social justice. Use the procedure in use will be the historiccomparative procedure, in order to demonstrate the legality of the public act as a maximum attempt to preserve the balance between the expansion of public services in various sectors of the economy, and the preservation of property rights, through regulation

Os conselhos como mecanismos de democratização da política educacional :participação e poder de decisão nas ações do Conselho de Controle Social do FUNDEF no município de Parnamirim/RN

This study board the FUNDEF social control council implementation in Parnamirim/RN city, concerning their representatives participation in the accompaniment (decision power) in resort, in front of governmental politics of decentralization, unleashed in 90´s, seen in decentralization process needs the society participation in decisions of educative institutions and represent an efficient way of solve the problems difficult the educational management actions. For this, the council creation of Brazil manager configure, since the 80´s, detaching, and the single characterizing, in actual context. The objective is raise pertinent questions of thematic of representatives members participation of collegiate organs, evidencing the decision power of these, in public resource control. The theory-methodological referential the literature treat the participation and power decision of FUNDEF social control decision, such as politics directrix that rules this council. It utilizes as proceeding of collecting data the semi-structured interview and analyze of meeting register to understand the empirics of council implantation in this city, in view of that the electoral process configured in 2003, showed as a innovation, because the counselor is indicated by the local public power representatives (in this case the education municipal secretary). The research result show the representatives have difficult, to accompany the FUNDEF resources amount, particularly in concern in the financial resources (ratio) over plus. Finally, emphasize the importance of democratization in the relations between the state and civil society, elucidating and exciting reflections a: democratic participation in control of public recourses for education, educational management and civil society mobilization in access of public and cultural cash which the citizen has rights

Competitividade dos produtores rurais de cana-de-açúcar da região agreste do Rio Grande do Norte

Deregulation of the sugar-alcohol sector in the 90s meant that agribusiness firms begin a process of reorganization of their production structures to enhance their abilities to become competitive in the new scenario. This study aims to examine the Production Chain of Sugar cane in Agreste region of Rio Grande do Norte, with studies to contribute to the competitiveness of farmers giving grants for planning and implementing policies, programs and projects, public and / or private. The method used in the study was researching the literature on the history of sugar cane in Brazil, agribusiness management, production chains and competitiveness, in field research used a questionnaire to collect information from farmers. It is concluded that the rural producers of cane sugar in newborns are not competitive and therefore it is necessary policies and / or for private gain in competitiveness of producers and consequently the production chain. It is hoped that the study serves as a subsidy for those policies proposição

The corporative strategies have been systematically changing since the middle of the 90´s by including measurement of satisfaction and loyalty of the consumers in their organization. strategies. This essay presents a study on the factors that influence on the satisfaction and loyalty of the consumers, and is based on national models of satisfaction rates. For this essay, the new Norwegian model was used. During the period of 01/06/03 until 02/14/03, a field research was developed and applied to 230 tourists visiting the city of Natal/RN

Cartas oficiais norte-riograndenses dos séculos XVIII, XIX e XX : constituição e caracterização de um corpus diacrônico

The diachronic studies marked the first decades of the 20th century in Brazilian linguistics, passing by an ostracism period after the 50s. Mainly from the 90s especially with the project, created in 1997, Para a história do português brasileiro (PHPB), which has systemized, in national ambit, the programme related to the area of diachrony the historical studies retake forces and have gradually increased since then. Our work is set in the new scene of Brazilian historical linguistics and it is associated to two research programmes: i) the constitution of a diachronic corpus; ii) the diachrony of text and discourse. As regards the first programme, we made effort to constitute a diachronic corpus of official letters about Rio Grande do Norte, we called cartas oficiais norte-rio-grandenses, written in 18th, 19th and 20th centuries. The chosen for bureaucrat letters occurred for they represent a textual category very productive in historical contexts, mostly 18th and 19th centuries, in which the command of writing was the least and also because they bring, almost always explicitly, the information of where, when, for whom and from whom, as remembers Fonseca (2003). The rules for constituting the corpus were based, although not strictly, on the orientation from PHPB. In respect to the second programme, we set up on the ideas of coserian base came from the studies on discourse traditions (TD) (Koch, 1997; Kabatek, 2006) amongst which that the texts are shaped so as to follow their own tradition (Coseriu, 2007), and we turned to Diplomatics (Belloto, 2002) in order to do the characterization of this corpus by the application of concepts from Diplomatics and TD as well as by the presentation of the structures that form those official letters: their textual genres, a kind of TD, with their macrostructures; and some of their formulaic expressions (microstructures), another sort of TD. This stage of characterizing will pay attention, as far as possible, to the dynamic between tradition and innovation that happen in the actualization of those textual structures along the centuries. This work intends to contribute with the researches connected to Historical Linguistics in Rio Grande do Norte, more specifically the ones related to the constitution of diachronic corpora and to TD; and with the study of official documents, textual category about which there are almost no studies (cf. Silveira, 2007)

A Transposição Didádica dos Gêneros do domínio do discursivo publicitários nos livros didáticos

Advertising text has been a subject of many investigations, because of its multimodal universe. Embodied by a linguistic and discursive materiality laying on scene persuasion, argumentation and power imagery of multissemiotics elements, the advertising text acts as an instrument of power, creating and destroying, promising and denying (CARVALHO, 2007). Advertising not only invites us to act for it, but directs us to look at it. It was under this moving look - of charm and interrogations - that discussions raised in this research were born. Investigations are directed to the school environment, in special, for the discursive advertising domain in Portuguese Language Textbook. It is from this environment that was born our research whose main objective is to analyze how does the didactic transposition of textual genres, described by Marcuschi (2008) as belonging to the "advertising" discourse domain (focusing on advertising genre) in didactic books teaching Portuguese Language before and after the advent of the PCN. Textbooks taken as reference for the study are historically situated in the 90s of the twentieth century and 10 century. Such books refer to elected 7th and 8th grades, currently corresponding to the 8th and 9th grades of elementary school. The choice is justified by the fact that in these Textbook teaching series the presence of advertising domain is recurrent and "didactized". In addition, we are also concerned in analyzing books that circulated around us and our regional reality. Hence, we elected books that were used by two public high schools: Municipal School Clementina Ana da Conceição in Jaçanã city in the Rio Grande do Norte state, State School for Elementary and High school Carlota Barreira in Areia city, Paraíba state. In our research the following categories of analysis were highlighted: (1) presence of advertising in DB, (2) fluctuation terminology: concepts and classifications; (3) The complexity of concepts facilitation, (4) what they propagate, and from which nature are the explored advertisements. From our analysis, we observe how the treatment of textual "advertising" genres have been inserted into Textbooks, and how occurs, in general, their didactic transposition. Focusing on the issue of fluctuating terminology, we noted the difficulty in drawing boundaries between the genres of advertising domain in the Textbooks. However, this also would result in the complexity - in the field of scientific knowledge - of delimiting genres of the same domain. To accomplish our studies, it was required a thorough and systematic dialogue with theories regarding the concept of "Didactic Transposition", due to the theoretical Chevallard Yves (1991), research on the textual genres - Bezerra (2005), Marcuschi (2008), Bazerman (2005), Swales (2004), among others - and studies involving the field of "Advertising" - Sandmann (2002), Carvalho (2007) and others

Síntese, caracterização e aplicação do MCM-41 e A1-MCM-41 na pirólise do resíduo atmosférico de petróleo

In present work, mesoporous materials of the M41S family were synthesized, which were discovered in the early 90s by researchers from Mobil Oil Corporation, thus allowing new perspectives in the field of catalysis. One of the most important members of this family is the MCM-41, which has a hexagonal array of mesopores with pore diameters ranging from 2 to 10 nm and a high surface area, enabling it to become very promising for the use as a catalyst in the refining of oil in the catalytic cracking process, since the mesopores facilitate the access of large hydrocarbon molecules, thereby increasing the production of light products, that are in high demand in the market. The addition of aluminum in the structure of MCM-41 increases the acidity of the material, making it more beneficial for application in the petrochemical industry. The mesoporous materials MCM-41 and Al-MCM-41 (ratio Si / Al = 50) were synthesized through the hydrothermal method, starting with silica gel, NaOH and distilled water. CTMABr was used as template, for structural guiding. In Al-MCM-41 the same reactants were used, with the adding of pseudoboehmite (as a source of aluminum) in the synthesis gel. The syntheses were carried out over a period of four days with a daily adjustment of pH. The optimum conditions of calcination for the removal of the organic template (CTMABr) were discovered through TG / DTG and also through analysis by XRD, FTIR and Nitrogen Adsorption. It was found that both the method of hydrothermal synthesis and calcination conditions of the studies based on TG were promising for the production of mesoporous materials with a high degree of hexagonal array. The acidic properties of the materials were determined by desorption of n-butylamine via thermogravimetry. One proved that the addition of aluminum in the structure of MCM-41 promoted an increase in the acidity of the catalyst. To check the catalytic activity of these materials, a sample of Atmospheric Residue (RAT) that is derived from atmospheric distillation of oil from the Pole of Guamaré- RN was used. This sample was previously characterized by various techniques such as Thermogravimetry, FTIR and XRF, where through thermal analysis of a comparative study between the thermal degradation of the RAT, the RAT pyrolysis + MCM-41 and RAT + Al- MCM-41. It was found that the Al-MCM-41 was most satisfactory in the promotion of a catalytic effect on the pyrolysis of the RAT, as the cracking of heavy products in the waste occurred at temperatures lower than those observed for the pyrolysis with MCM-41, and thereby also decreasing the energy of activation for the process and increasing the rates of conversion of residue into lighter products

A residência secundária e uso do espaço público no litoral oriental potiguar

Considering that tourism tends to reproduce itself privatizing the areas where it installs, the secondary residence has been an urban element responsible for the private appropriation of the public spaces of coastal of Nísia Floresta. The private appropriation of these accesses, for secondary residences, constitute in an issue-problem of the research. The principal goal is to analyze the relationship of the consumers/users of secondary residences with the public space; and, specifically, identify how the government has been acting and manifesting itself about the occupation of the coastal of Nísia Floresta; as also to verify how the secondary residence has been appropriating privately of the public access of the coastal. On account of the scarce literature about secondary residences and the importance of the public access to beaches for the inhabitant, the present work aims to contribute to the discussion of this theme. The secondary residences in Rio Grande do Norte began in the late nineteenth century, becoming more common in the 90s, when the coast south of Natal is appropriated from local vacationers. In 2000, foreign investment began to be applied in real state and tourism, producing closed developments, served in leisure infrastructure, trade, and hospitality, mainly to external demands. The methodology included a bibliographic survey, data collection and in lócus observation. Applied questionnaires and interviews were performed with consumers/users of the secondary residences, permanent residents and government, respectively. To the legal grounding, taken as a reference the article. 10, of the law 7.661/88 to establish that the beaches are goods of common use . Considering the conclusive analysis of the research, can be said that the right of free access and use of the beach is committed for the benefit of the consumers/users of secondary residences, due to the negligence and omission of the government

Análise de desempenho de algoritmos de compressão de dados com perda para aplicações industriais

The great amount of data generated as the result of the automation and process supervision in industry implies in two problems: a big demand of storage in discs and the difficulty in streaming this data through a telecommunications link. The lossy data compression algorithms were born in the 90’s with the goal of solving these problems and, by consequence, industries started to use those algorithms in industrial supervision systems to compress data in real time. These algorithms were projected to eliminate redundant and undesired information in a efficient and simple way. However, those algorithms parameters must be set for each process variable, becoming impracticable to configure this parameters for each variable in case of systems that monitor thousands of them. In that context, this paper propose the algorithm Adaptive Swinging Door Trending that consists in a adaptation of the Swinging Door Trending, as this main parameters are adjusted dynamically by the analysis of the signal tendencies in real time. It’s also proposed a comparative analysis of performance in lossy data compression algorithms applied on time series process variables and dynamometer cards. The algorithms used to compare were the piecewise linear and the transforms.
