Setor informal da economia e a dinâmica dos territórios nas praias da cidade do Natal/RN

La recherche sur secteur non-formel de l économie et la dynamique des territoires dans les plages de la ville de Natal/RN, a le but de la compréhension des espaces de ces territoires ainsi que leurs caractéristiques; le rapport des acteurs sociaux et l existence de politiques dirigées direct ou indirectement vers ce secteur de l économie et ses territoires. Pour celà, on donne emphase au scénario économique moulé par le système de production et reproduction dans la mondialisation, ce qui, parmis d autres actions aq l inetrférence sur le marché du travail, lequel subit constamment des transformations importantes cherchant à suivre les changements en niveau global, en devenant, pour ainsi dire, un marché chaque fois plus exigeant et, conséquemment, sélectif. Moyennant la réalité économique et politique vécue, il augmente le nombre de chômeurs dans le pays suscitant, à tort et à travers, la croissance du secteur non-formel de l économie avec ses inombrables travailleurs qui occupent les plus différents segments parmi lesquels les travaux autonomes, ici représentés par les camelots, les propriétaires de baraques, les propriétaires de kiosques ; etc. Pour atteindre ce but, on a cherché les reférenciels théorico-scientifiques ayant pour base la connaissance empirique à travers les inombrables cas d études matérialisés au moyen de donnés primaires et sécondaires. Finalement, on est sûr de ce que les travailleurs du secteur non-formel complèmentent la chaîne repoductive, ils créent et recréent des territoires avec des contenus variés qui sont indispensables pour la croissance et le développement social

A construção e estruturação do território comercial no bairro Alecrim Natal/RN

The study done has as objective the comprehension of the constructed territorial spaces through the commercial perspective, because it is a social practice which enables the dynamic of the space and the appearing of territories. Related to the territory, we emphasized the interest for the idea of used territory treated by Milton Santos, because we agreed with him believing that is the use of the territory which warrants its legitimacy. Then, the spatial dimension chose concentrates itself into the district of Alecrim, localized at the east zone of Natal/RN, where it is recognized by its strong commercial dynamic which was built during years, facing some events which happened in the context of the city. However, this dynamic counts with a hard dichotomy which involves as the considered by the State formal activities, as the informal one. About the commerce of the district, it has characteristics into its activities whose make him to be considered popular, as by the existing products, as by the strong presence of informal workers that constitutes the district s landscape. The informal workers practice expresses one of the multiples constructed alternative territorialities. We believe that this fact has direct relation with the growing process of the exclusion from the formal jobs market. Still talking about the spatial dimension, this real example of the Alecrim district shows how the techniques changes, together with the capitalism process, may influence one entire spatial dynamic across years, involving many agents, since the transient people from somewhere, until the State. Shall the Geography understand the multiple forms from the space, face to the relations that occur into it and also how new territories have been built

Formação e capacitação profissional no setor hoteleiro de Ponta Negra, Natal/RN

This paper aims to analyse and discuss the labour in hospitality industry, specially the hospitality trade in Ponta Negra Natal/RN, Brazil, since the tourism has increased in the city, by investigating if the tourism field is suitable for public politics programs and labour qualification. The choice for Ponta Negra is because it has become the focus of tourism development in Natal. The research was developed by using qualitative approach of investigation, by means of some procedures such as: bibliographic and empirical researches, by using questionnaires with workers and recruiting personnel of hotels, always following a theory and a reflexive descriptive attitude. This dissertation involves eight chapters: Neoliberalism and labour; Economical and spatial restructuring of Rio Grande do Norte; Public politics concerning tourism area; Tourism, graduation and qualification in hospitality industry; Qualification for tourism hospitality; Hotels: territorialization and unterritorialization; Social qualification reality of people involved in hospitality activities in Ponta Negra, Natal/RN, Brazil; and Final considerations and recommendations. Therefore, this paper intends to contribute for understanding professional qualification in hospitality trade, confronting the needs that the service requires, and mainly, in the tourism sector, which is increasing in our city, Natal

Síndrome de insuficiência androgênica: critérios diagnósticos e terapêuticos

A síndrome da insuficiência androgênica na mulher (SIA) desperta, mesmo nos dias atuais, muitas discussões e encerra muitas controvérsias. Sabe-se, no entanto, que os níveis plasmáticos de testosterona declinam progressivamente ao longo do período reprodutivo. Conceitua-se a SIA como o conjunto de sintomas clínicos, a presença de biodisponibilidade diminuída de testosterona e os níveis normais de estrogênios. Entre os principais sintomas, citam-se o comprometimento do bem-estar, o humor disfórico, a fadiga sem causa aparente, o comprometimento do desejo sexual, o emagrecimento e a instabilidade vasomotora em mulheres pós-menopáusicas sob terapêutica estrogênica. Esses sintomas, no entanto, são potencialmente atribuíveis a diferentes etiologias e dificultam o correto diagnóstico na maioria dos casos, ainda que ele seja lembrado com freqüência em pacientes que se submetem à ooforectomia bilateral. O diagnóstico da SIA parece ser essencialmente clínico, não havendo a necessidade das dosagens laboratoriais para a sua comprovação. Não se deve indicar a terapêutica androgênica (TA) em pacientes que não estejam adequadamente estrogenizadas. Considera-se a testosterona o hormônio ideal para a TA. As pacientes com sintomas sugestivos de SIA, excluídas outras causas identificáveis, especialmente se pós-menopáusicas, são candidatas à TA. Não existem dados de segurança sobre a TA em usuárias em longo prazo. A via transdérmica - através de adesivos, cremes e gel - parece ser preferível à oral.

Crystallization and preliminary x-ray analysis of Parkia pendula lectin

Lectins are proteins important in various biological processes such as infection, cell differentiation and metastasis. The Parkia pendula lectin has been crystallized using the hanging-drop vapour diffusion method. X-ray diffraction data were collected using a Rigaku RU300 rotating anode generator and R-AXIS IV diffractometer. The cell parameters for P. pendula lectin are a=93.7 Angstrom b=161.1 Angstrom, c=80.0 Angstrom and space group C222. The maximum resolution was of 2.98 Angstrom. These data showed a R-sym=12.8%.

Crystallization and preliminary X-ray analysis of S-III-SPIII, a phospholipase A2 isolated from the venom of Bothrops jararacussu.

Large single crystals have been obtained of S-III-SPIII, a phospholipase A(2) from the venom of Bothrops jararacussu. The crystals belong to the orthorhombic system space group C222, and diffract X-rays to a resolution of 1.9 Angstrom. Preliminary analysis reveals the presence of one molecule in the crystallographic asymmetric unit. The crystal structure is currently being determined using molecular replacement techniques.

Sibutramine Effects on the Reproductive Performance of Pregnant Overweight and Non-Overweight rats

It is well established that sibutramine produces weight loss and is used frequently in women of childbearing age. However, the potential adverse consequences attributed to sibutramine use by women who may become pregnant is not known. It was thus of interest to determine the effects of sibutramine on the reproductive performance of pregnant rats. Overweight as well as non-overweight female Wistar rats were treated with sibutramine (6 mg/kg) orally, daily for 15 d and then mated with normal male rats. Pregnancy was confirmed and treatment continued with sibutramine until d 14 of pregnancy. on d 20 of pregnancy all rats were anesthetized for determination of various maternal and fetal parameters. There was a significant maternal weight reduction at the end of pregnancy in the non-overweight drug-treated group compared to the control (non-overweight, no drug). Sibutramine alone and overweight condition alone produced a significant increase in postimplantation loss and placental index. In the overweight with or without sibutramine groups a significant decrease in fetal weight was noted. Data suggest that sibutramine alone or the condition of excess weight in the absence of drugs produced impaired reproductive performance. However, treatment of overweight rats with sibutramine did not further exacerbate fetal loss compared to sibutramine alone or the effects noted with excess weight alone.
