A corretagem de imóveis no Rio Grande do Norte: das práticas históricas à emergência como segmento integrante da fração imobiliária do capital

This research proposed to question the development of what was defined as historical practices (commercial, social and political institutions), of the economic activity of the real estate brokerage in the Rio Grande do Norte from the progressive institutionalization of economic agents - individuals (realtors) and legal (real estate) - based on two main approaches: a) the development of economic activity as an integral segment of a fraction of capital (POULANTZAs, 1985; LESSA, 1981). This work set out from a socio-historical approach of the historical practices development the of real estate brokerage in Brazil started in the Southeast, especially in the cities of Rio de Janeiro and São Paulo as a result of the "expansion of capitalist relations by the housing sector" (RIBEIRO , 1996). especially the real estate capital ; b) the historical development of relations between labor and capital within the activity, in other words, the development of the relationship between realtors and Real Estate in relation to "group of interests" and their "collective actions" (OFFE, 1984). These historical practices are defined in this research as: 1) mercantile practices, times when there was no distinction between the activity of real estate brokerage and other forms of mercantile capital; 2) social practices, which began in the 1930s, when agents of real estate are to be distinguished from each other within the activity through Taylorist division of labor between workers realtors and developers of real estate; 3) political and institutional practices, initiated in 1962, characterized by State action, in the individualization and distinction of the agents of real estate brokerage as socioprofessional category regulated throughout Brazil by Law 4.116/62 and 6.530/78. The results achieved by the present study showed that in Rio Grande do Norte, due to the specifics as to the peripheral processes of urbanization of the constitution of the land market, as well as the process of conservative modernization of the oligarchic State from the 1960s (CLEMENTINE, 1995; FERREIRA, 1996, 2010, TRINDADE, 2004), the State was led to the development of a late manifestation of the historical practices of real estate brokerage. In other words, it was a process in which historical practices, in particular social practices, not fully developed, mitigating, thus the perception of realtors from his position in the process of exploitation of labor by the Real Estate. And, as a result, of their collective interests front of them.

Asymmetric post-natal development of superior cervical ganglion of paca (Agouti paca)

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

The Developing Left Superior Cervical Ganglion of Pacas (Agouti Paca)

In this study the main question investigated was the number and size of both binucleate and mononucleate superior cervical ganglion (SCG) neurons and, whether post-natal development would affect these parameters. Twenty left SCGs from 20 male pacas were used. Four different ages were investigated, that is newborn (4 days), young (45 days), adult (2 years), and aged animals (7 years). By using design-based stereo-logical methods, that is the Cavalieri principle and a physical disector combined with serial sectioning, the total volume of ganglion and total number of mononucleate and binucleate neurons were estimated. Furthermore, the mean perikaryal (somal) volume of mononucleate and binucleate neurons was estimated using the vertical nucleator. The main findings of this study were a 154% increase in the SCG volume, a 95% increase in the total number of mononucleate SCG neurons and a 50% increase in the total volume of SCG neurons. In conclusion, apart from neuron number, different adaptive mechanisms may coexist in the autonomic nervous system to guarantee a functional homeostasis during ageing, which is not always associated with neuron losses.

A influência da cultura organizacional na adoção de práticas de qualidade Seis Sigma: um estudo exploratório no segmento de farmácia de manipulação do Estado do Rio Grand do Norte

In recent debates about the issues of quality, the theme organizational culture and Six Sigma has appeared ever more frequently. In this context several authors suggest that the adoption of Six Sigma practices is influenced by culture. This work focuses on the relationship of organizational culture and quality to the practices of Six Sigma quality. Thus a descriptive-exploratory and correlational study of forty pharmacies of manipulation from Rio Grande do Norte was undertaken. Data collection identified features of companies and the level of use of the practices of Six Sigma quality that have been identified in the literature. For the Organizational Culture evaluation was used the Competitive Value Model (Cameron & Quinn, 1996), tested on north-American organizations and considered a high value academic and professional instrument. This model has been involved with the taximetrics created by Cameron who classifies quality culture in four levels. The results suggest that the Group and Developmental cultures are associated with higher levels of use of the practices of Six Sigma quality than the Rational and Hierarchical Cultures. Regarding the levels of the culture s quality, the highest levels were most frequently cited in Errors Prevention and Perpetual Improvement and Creativity, being the last one more positively related to the Six Sigma indicators

Utilização de soluções business-to-business (B2B) no segmento downstream da cadeia de suprimentos de uma distribuidora de combustíveis

The pursuit of competitive advantage is lobbying organizations to strategically plan the use of their material, human, technological and financial resources, so that it s possible to add value to the product, even when it is considered a commodity. The scenario for this planning should not be limited to the company in question, but cover an entire supply chain, which is composed of several organizations which have common goals of growth and sustainability of the market. They should form trade links, integrating the chains of individual values, in a perspective of value system. In this supply chain there is a flow of services, payments and information, as products well as. The training of these links can be supported by the adoption of a set of information technology, here called solutions business-to-business (B2B), which will be responsible for the production, storage and distribution of relevant information to business transactions between the companies involved. On this view, this thesis aims to describe the B2B solutions adopted in the downstream segment of the supply chain of a distributor of fuel and the nature of these technologies as well as their impact on the creation of value for business and optimization of the relationship between companies. This is a case study on a national distributor of fuels, from a model of research produced under the influence of theories of integrated logistics system and value of Michael Porter. The analyses came to the conclusion that information technology is perceived as an essential tool to the operation of all activities carried out by the company. Among them, at was also brought the key activities of integrated logistics: administration of applications, inventory management, management transport and customer services, which were highlighted in this study. It was also noticed that even these activities are, in principle, purely operational; they all had in the adoption of strategies for leadership in cost or differentiation, supported by B2B solutions identified, making it more conducive to business and direct customer, the clinic reseller of fuel, to obtain value and benefits of this market segment as competitive

Estratégia de gestão ambiental baseada nos princípios da produção mais limpa : um estudo de caso focado no segmento da carcinicultura

The objective of this scientific article is to introduce the opportunities of implementation of cleaner production (CP) in a shrimp culture farm. The methodology used for this was exploratory research implemented in a production unit located in the Northeast Brazil. The scientific article approaches since generic aspects of the technique about the management to use water, energy and the effluent characterization of this productive activity. It discusses quantitative aspects, environmental questions and chances of P+L during the productive process phases. The results points to input economy in the form of feed, soil correctives, medicines, and energy applied to the process, which range from 4% to 27%, emphasizing the small profit should be viewed as a source of considerable environment return. The authors conclude for the adoption property of this technique in this agribusiness segment, point out to the management importance of the input dosage in the quality of the final effluent, besides the adoption of a physical-chemistry remediation mechanism to the residual of Sodium metabissulphite used in the process of shrimp caught

Desenvolvimento da Tecnologia de Soldagem do Titânio pelo Processo TIG Orbital no Segmento Aeroespacial Brasileiro - Parte 2: Caracterização das Juntas Soldadas

In this work, three welding programs for orbital TIG previously developed were used, using pulsed current and increasing speed (M), constant current (#B) and pulsed current and decreasing current (#C). One of those should be used for the propulsion system of the satellite CBERS (CHINA-BRAZIL EARTH RESOURCES SATELLITE). Welded joints using tubes of commercially pure titanium were obtained with these procedures, which were characterized by means of mechanical and metallographic tests. The obtained results show that the three welding procedures produce welded joints free of defects and with adequate shape. Although small differences on mechanical properties and microstructure have been observed, the three welding programs attained compatible results with international standards used in the aerospace segment. The welding program #B, due the reduced heat input used, was considered to obtain slightly advantage over the others.

Tireóide ectópica cervical lateral: Relato de caso e revisão da literatura

Tireóide ectópica é qualquer tecido tireoideano localizado fora de sua topografia habitual, podendo apresentar-se na linha mediana do pescoço ou, mais raramente, na região cervical lateral. Algumas teorias tentam explicar a origem do tecido tireoideano ectópico: 1. falha na descida da glândula; 2. seqüestro de nódulos tireoideanos; 3. presença de tecido tireoideano na cápsula de linfonodos cervicais; 4. formação teratomatosa; 5. Secundário a anomalias branquiais. Na abordagem diagnóstica, diversos exames têm sido utilizados, sendo o diagnóstico definitivo algumas vezes fornecido apenas pelo estudo histopatológico. Apesar das controvérsias em relação às abordagens terapêuticas apresentadas na literatura, é necessário um planejamento rigoroso para evitar iatrogenias. Conclui-se que a presença de tecido tireoideano ectópico deve ser lembrada no diagnóstico diferencial de massas cervicais laterais, e sua origem histológica considerada, sendo na maioria das vezes metástase de um carcinoma tireoideano oculto. Os autores relatam um caso de tecido tireoideano ectópico lateral no pescoço, em paciente do sexo feminino com bócio colóide mergulhante. Foram realizadas considerações importantes sobre dismorfogênese tireoideana, métodos diagnósticos e opções de tratamento, com revisão da literatura das últimas cinco décadas.

Prevalência de lesões cutâneas actínicas em pacientes com carcinoma basocelular do segmento cefálico: um estudo caso-controle

OBJETIVO: Avaliar a prevalência de lesões cutâneas actínicas em portadores de carcinoma basocelular do segmento cefálico. MÉTODOS: Foi conduzido estudo tipo caso-controle. Os casos, constituídos por pacientes com carcinoma basocelular sólido, primário, menor que dois centímetros, no segmento cefálico; e controles, por pacientes com outras dermatoses. Foram analisadas variáveis constitucionais, comportamentais e lesões actínicas. RESULTADOS: Avaliaram-se 120 casos e 360 controles. Mílio facial (OR = 2,3), leucodermia puntacta de membros superiores (OR = 2,9) e cutis romboidalis nuchae (OR = 1,8) associaram-se à neoplasia independentemente das demais variáveis, sugerindo um fenótipo de risco. Houve ainda associação com fenótipos claros, genética familiar e exposição solar cumulativa. Queimadura solar, tabagismo e alcoolismo não foram identificados como fatores de risco. O uso de fotoprotetores não evidenciou proteção; porém, o grupo controle era composto por pacientes dermatológicos, aos quais são indicados fotoprotetores regularmente. CONCLUSÃO: Lesões actínicas foram mais prevalentes em portadores de carcinoma basocelular sólido do segmento cefálico que em controles, especialmente mílio, cutis romboidalis nuchae e leucodermia puntacta, independentemente dos demais fatores de risco conhecidos.

Experimento de fluxo de sedimentos em um segmento de campo de dunas eólicas costeiras de Jenipabu - Litoral oriental do Rio Grande do Norte.

This study analyzed measurements of the aeolian transport using vertical sand traps across the field dunes of Jenipabu, in the municipality of Extremoz, Rio Grande do Norte state to the North of Natal city. These measurements were used as parameters for the sand aeolian transport in the region. Before the field trips a map of landscape units was made. Three visits to the field were done in September 2011 (field a - the 13th, field b - the 21st, field c - the 29th), period of the year with the highest wind speed, and another in December 8th, 2011 (field d ) when the wind speed starts to decrease. The sand traps used were of the type "I" with collecting opening of 25 cm from the surface level, and type "S" with collecting opening of 25 cm located 25 cm from the surface level in six collecting points in two of the visits (fields a and d ), and sand traps of the type "T" with the collecting opening of 50 cm from the surface level in the other field trips (fields "b" and "c"). A set of records was also collected by using a portable meteorological station complemented with information such as frequency and intensity of winds, precipitation and relative air humidity in the region, from the Estação Meteorológica de Natal , located 12 km from the study area. The sediments collected were treated and the data obtained permitted calculating the ratio of sediment transport. In September, the sedimentation ratio varied from 0.01 to 11.39 kg.m-1.h-1 and in December this ratio varied from 0.33 to 1.30 kg.m-1.h-1 in the type T collectors. In type I collectors they ranged from 0.01 to 11.39 kg.m-1.h-1, while the same parameters varied from 0.01 to 0.73 kg.m-1.h-1 in type S collector. Based on the statistical analysis done, we concluded that the sediment transport increased proportionally to the wind speed 25 cm from the surface. However, this is not true above 25 cm from the surface. The transport of sediments is more intense near the surface where sedimentation ratios greater than 10 kg.m-1.h-1 were found, whilst a maximum value of 3 kg.m-1.h-1 was observed 25 cm below the surface. The volume of sediments collected increases with the increasing wind speed at the surface level, whereas this relationship is opposed far away from that surface

Cervical Lactobacillus and leukocyte infiltration in preterm premature rupture of membranes

Objectives: To evaluate the possible association between microorganisms present in the cervical secretions and amniotic fluid of pregnant women with preterm premature rupture of membranes (PPROM), and histologic chorioamnionitis. Methods: Thirty-seven pregnant women with PPROM and 21 healthy pregnant women were studied. Secretions from the cervical canal and amniotic fluid were collected to isolate microorganisms present in the genital tract. Cervical smears were Gram stained and evaluated microscopically. At delivery, chorioamniotic membranes were collected for histopathologic analysis. Results: Microscopic examination of the cervical secretion smears obtained from the PPROM group showed a low rate of Lactobacillus species, large numbers of leukocytes, and a wide diversity of microorganisms compared with the control group. The PPROM group presented an 80% rate of chorioamnionitis. Staphylococcus aureus isolation in cervical secretion was associated with intense inflammatory infiltrate in the membranes and might play a role in the pathogenesis of PPROM. Conclusions: the low colonization of cervical flora by Lactobacillus species associated with an intense leukocyte infiltrate detected in Gram-stained cervical smears can be considered a rapid method of detecting chorioamnionitis in pregnant women with PPROM.

Analysis of systemic inflammatory response in the carcinogenic process of uterine cervical neoplasia

The inflammatory response is an active process in cervical cancer and may act in the progression and/or regression of the lesion. At the site of inflammation, macrophages and neutrophils are present as well as cytokines such as TNF-alpha and IFN-gamma. This study aims to evaluate the inflammatory response levels in women with cervical intraepithelial lesions (CIN) and with squamous cell carcinoma (SCC) of the cervix. Serum samples obtained from women without evidence of disease (n = 30), with CIN (n = 30) and with SCC of the cervix (n = 30) were analyzed for the activities of N-acetylglucosaminidase (NAG) and myeloperoxidase (MPO) by enzymatic assay and the serum levels of TNF-alpha and IFN-gamma by ELISA assay. The activities of NAG and MPO and the level of TNF-alpha were higher in women with CIN compared to the women with SCC. The levels of IFN-gamma were lower in the group of women with CIN compared to the group with SCC. There was not a significant association between the degree of the CIN and the staging of the SCC of the cervix and the degree of inflammation as assessed by the levels of inflammatory markers. The inflammatory response was inversely correlated with the progression of the carcinogenic process. In the three groups, the control group, women with CIN and women with invasive SCC, there was no association between the degree of preinvasive lesions and staging of the SCC of the cervix.
