Análises de elementos arquitetônicos de proteção solar em edificações institucionais na cidade de Natal/RN Diretrizes projetuais

The present work concerns the use of shade elements as architectural elements to block sunlight in public buildings. In a city like Natal, (5o South) the incidence of sunrays in any type of design should be a constant concern for all the architects. Besides, this habit of avoiding insolation in the environment is not a common practice. Within this context, the present work has the objective to dig deep into the knowledge of solar control, studying some cases and verifying its function according to the orientation and the original design of the building, having in mind if the shade elements usually used in the region have achieved their purpose of providing protection against the incidence of direct sun rays. This study considers the position of the shade element (horizontal and vertical), the angle formed between them and the respective facades, and the local of the buildings in relation to their orientation during the summer, winter and equinox solstice. As supporting instruments the solar map of the city and the protractor, for measuring shade angles, were used. It was concluded that in all the cases studied, it was not possible to obtain the maximum use of the elements. It was verified that the best type of shade element (more efficient) for the city of Natal is the mixed type (horizontal and vertical) and that the vertical shade elements are more efficient in the early mornings and late afternoon. The horizontal shade elements are used more effective at midday. We intend to present the results of this study to the architects in the region in order to show them the correct ways of using the shade elements according to the possible orientation on the facade, as a supporting tool at the time of designing a project as well as a subsidy for further discussions on the elaboration of the new urban standards for the city of Natal/RN

Fucana ativa via das Map quinases e inibe a proliferação de células de ovário de hamster chinês (CHO)

Fucan is a term used to denominate L-fucose rich sulfated polysaccharides. The fucans have been studied due their pharmacological activities like antithrombotic, antiproliferative and antioxidant. We have extracted three fucan fractions from the brown seaweed Spatoglossum schröederi. These fucans were denominated Fuc B 1, Fuc B 1.5 and Fuc B 2. The chemical analyzes show that the fucans have very similar composition as demonstrated by agarose electrophoresis gel, sugar and sulfate content. The antiproliferative effect was determined by MTT and BrdU methodologies in CHO cells. The inhibition of proliferation effect of the three fractions was about 40%. Therefore this we proceed just with the Fuc B 2 due the higher yield. There is no apoptosis indication using the anexin V/propidium iodide test. We found a cell cycle phase G1 arrest. The western blotting show that the PKC; pFAK; pERK 1/2 are activated when the cells were treated with fucans. The treatement with inhibitor of MAPK PD98059 extinguished the fucan effect. These results indicates that fucan act by the ERK pathway inducing the cell death.

Mapa de Conteúdos e Mapa de Dependências:Ferramentas Pedagógicas para uma Metodologia de Planejamento baseada em Objetivos Educacionais e sua Implementação em um Ambiente Virtual de Aprendizagem

Furthered mainly by new technologies, the expansion of distance education has created a demand for tools and methodologies to enhance teaching techniques based on proven pedagogical theories. Such methodologies must also be applied in the so-called Virtual Learning Environments. The aim of this work is to present a planning methodology based on known pedagogical theories which contributes to the incorporation of assessment in the process of teaching and learning. With this in mind, the pertinent literature was reviewed in order to identify the key pedagogical concepts needed to the definition of this methodology and a descriptive approach was used to establish current relations between this conceptual framework and distance education. As a result of this procedure, the Contents Map and the Dependence Map were specified and implemented, two teaching tools that promote the planning of a course by taking into account assessment still in this early stage. Inserted on Moodle, the developed tools were tested in a course of distance learning for practical observation of the involved concepts. It could be verified that the methodology proposed by the above-mentioned tools is in fact helpful in course planning and in strengthening educational assessment, placing the student as central element in the process of teaching and learning
