The present work analyzes the fast evolution of gated communities in Natal-RN´s urban space. Characterized by the occupation of large areas, providing private security and utilities, this kind of real estate use arises a long list of questions and issues from society and scholars, due to privatization of urban space, bending of law constraints and the lack of an integrated planning of the cities where they are built. The reasons for its fast growth in Brazil s urban areas are analyzed, considering the impact on formal urban planning and municipal services and on the identification of urbanistic, architectural pattern and constraints, as well as legal, social and economic issues. This study is based on the detailed analysis of the first three units of gated communities built in the urban space in Natal, between 1995 and 2003, including their evolution throughout time and the specific social and economic reasons for its present widespread adoption in Brazilian real estate market and, particulary, in our city. The main objective of this piece of work is to answer the why s and how s these phenomena evolved, setting a basis for the definition of adequate public policies and regulation of this kind of urban land use

Introducción: La medición de la actividad enzimática (AAAs) y del flujo de secreción (FSAAs) de la enzima alfa-amilasa salivar han sido propuestos por diversos grupos de investigación como posibles marcadores biológicos indirectos, no invasivos, y de bajo coste, del nivel de actividad noradrenérgica periférica/central. Dicha actividad noradrenérgica se sustenta, esencialmente, gracias a la actividad preponderante del denominado Sistema Locus Coeruleus-Noradrenalina (LC-NA), un sistema básico en la modulación de diversas funciones atencionales, cognitivas ejecutivas, así como en la regulación de los estados de ánimo. Material y Método: En nuestro estudio piloto (N = 13; 9 niños, 4 niñas; Edad media ± DT = 10,23 ± 1,53) se analizó la relación entre ambos marcadores salivares junto al parámetro flujo de secreción salivar total (registrados a lo largo de un proceso de evaluación neuropsicológica escolar) y diversas medidas auto (CDI; ansiedad, depresión y depresión total) y hetero-reportadas (escalas de psicopatología internalizada del TRF: ansiedad- depresión, depresión-aislamiento, alteraciones psicosomáticas y psicopatología internalizante total). Resultados: Los análisis estadísticos basados en el cálculo de coeficientes de correlación producto-momento de Pearson (de tipo parcial al controlar el efecto de la variable IMC), revelaron correlaciones estadísticamente significativas y directas entre el FSAAs y las puntuaciones en la escala ansiedad-depresión (p < 0,039) y psicopatología internalizante total del TRF (p < 0,012), así como una tendencia a la significación en el caso de las puntuaciones para la escala de alteraciones psicosomáticas (p = 0,054) de esa misma prueba. Del mismo modo, se observaron tendencias a la significación en la asociación directa entre las subescalas ansiedad-depresión (p = 0.065) y psicopatología internalizante total (p = 0.083) y la medida del flujo salivar total. Por otro lado, se observaron asociaciones inversas estadísticamente significativas entre la variable flujo salivar total y las puntuaciones de ansiedad (p < 0.01) y depresión total (p < 0.01) obtenidas a través del CDI. Discusión: Estos resultados preliminares de este estudio piloto abren una interesante línea de trabajo en nuestro laboratorio acerca de la utilidad de la medición de la AAAs, FSAAs y FST como posibles marcadores biológicos, no invasivos, y de bajo coste, aptos para su empleo con poblaciones pediátricas. Dichos marcadores, están relacionados con el grado de actividad noradrenérgica periférica/central desarrollada por el sistema LC y con la actividad del SNV, que a su vez están implicados en la regulación de los estados afectivos. Estudios recientes han mostrado bajos niveles basales de alfa-amilasa salivar en el caso de pacientes jóvenes diagnosticados de su primer episodio depresivo (Cubala y Landoski, 2014) y en participantes infantiles con mayor sintomatología depresiva heteroobservada (Vigil et al., 2006; Maldonado et al., 2014; Maldonado, enviado). Estos resultados complementan las observaciones realizadas anteriormente por nuestra laboratorio (Maldonado et al., 2014; Maldonado, enviado).

A self-flotator vibrational prototype electromechanical drive for treatment of oil and water emulsion or like emulsion is presented and evaluated. Oil production and refining to obtain derivatives is carried out under arrangements technically referred to as on-shore and off-shore, ie, on the continent and in the sea. In Brazil 80 % of the petroleum production is taken at sea and area of deployment and it cost scale are worrisome. It is associated, oily water production on a large scale, carrier 95% of the potential pollutant of activity whose final destination is the environment medium, terrestrial or maritime. Although diversified set of techniques and water treatment systems are in use or research, we propose an innovative system that operates in a sustainable way without chemical additives, for the good of the ecosystem. Labyrinth adsor-bent is used in metal spirals, and laboratory scale flow. Equipment and process patents are claimed. Treatments were performed at different flow rates and bands often monitored with control systems, some built, other bought for this purpose. Measurements of the levels of oil and grease (OGC) of efluents treaty remained within the range of legal framework under test conditions. Adsorbents were weighed before and after treatment for obtaining oil impregna-tion, the performance goal of vibratory action and treatment as a whole. Treatment technolo-gies in course are referenced, to compare performance, qualitatively and quantitatively. The vibration energy consumption is faced with and without conventional flotation and self-flotation. There are good prospects for the proposed, especially in reducing the residence time, by capillary action system. The impregnation dimensionless parameter was created and confronted with consecrated dimensionless parameters, on the vibrational version, such as Weber number and Froude number in quadratic form, referred to as vibrational criticality. Re-sults suggest limits to the vibration intensity

A cooperação apresenta-se como a base de qualquer organização, mas também das equipas desportivas. O comportamento cooperativo é influenciado pela estima e confiança que o indivíduo tem em si. A confiança entre os indivíduos resulta da mediação entre o comportamento de interesse próprio e o interesse pelo outro, promovendo desta forma a cooperação entre os membros. Vários autores referem as noções de competência relacionadas com comportamentos de confiança. Desta forma estudaram-se no presente estudo as correlações entre a cooperação desportiva e o auto-conceito de competência. A amostra foi constituída por 120 atletas do sexo masculino de equipas profissionais e semi-profissionais de futebol. Os instrumentos utilizados "Questionário de Cooperação Desportiva" e "Questionário de Auto-Conceito de Competência", revelaram possuir qualidades psicométicas aceitáveis. A análise dos resultados revelou correlações estatisticamente significativas entre a dimensão de cooperação situacional e as dimensões, cognitiva, social e criativa do auto-conceito de competência, assim como a dimensão de cooperação incondicionada com as dimensões cognitiva e social do auto-conceito de competência. /ABSTRACT: The cooperation comes as the foundation of any organization but also of sports teams. The cooperative behavior is influenced by the esteem and confidence that the individual has in himself. Trust between individuals result of mediation between the behavior of self-interest and concern for others, thereby promoting cooperation among members. Several authors refer to the notions of competence-related behaviors of confidence. Thus it was studied in the present study the correlations between the sporting cooperation and self-concept of competence. The sample was composed of 120 male athletes of professional teams and semi-professional football. The instruments used "Cooperation Sports Questionnaire" and "Self-Concept Questionnaire for Competence," have revealed qualities psicométicas acceptable. The results showed statistically significant correlations between the dimension of cooperation and situational dimensions, cognitive, social and creative self-concept of ability, as well as the size of unconditional cooperation with the cognitive and social dimensions of self-concept of competence.
