Thus, the present work aims to analyze software testing activities, regarding their applicability and importance in private companies. This is a descriptive research using a quantitative method, carried out with the participation of five software development companies in Rio Grande Norte, specifically in the cities of Caicó, Natal and Nova Cruz. Data collection took place through an adapted questionnaire with a total of twenty-two questions. From the analysis of the collected data, it was found that although the companies involved carry out the software tests, they do not carry out the activities aimed at documenting the process, surveying risks and preserving the tests performed, which can compromise the quality of the software. 2022-03-29T00:00:00Z http://memoria.ifrn.edu.br/handle/1044/1964 Influence of the synthesis time on the microsstructure and photophysical properties of Gd-MOFs doped with Eu3+ Metal Organic Frameworks (MOFs) are hybrid materials, usually crystalline, consisting of metallic species or clusters, connected by polytopic organic ligands originating bi or tridimensional porous structures. In this work, Gd-1,4-BDC-MOFs doped with 5% mol Eu3+ were synthesized via solvothermal method at 180°C. The effect of the synthesis time (3, 5 or 7 days) on the microstructure and photophysical properties of the obtained MOFs were evaluated. It was found that porous agglomerates were formed within three days, gradually changing their morphology to rod-like crystals within seven days. The photoluminescence excitation and emission spectra revealed an efficient energy transfer from the ligand to the Eu3+ levels (antenna effect), what is not expected for 1,4-BDC2- in a Eu(III)-based MOFs. We concluded that the presence of highly paramagnetic Gd3+ ions in the matrix enhanced the antenna effect, resulting in a strong red emission. 2017-01-09T00:00:00Z http://memoria.ifrn.edu.br/handle/1044/1854 Especificação e implementação de um protótipo para gerenciamento de projetos The Internet popularization has propitiated an improvement in how people make purchases, obtain information, disseminate their services and a number of other advantages. According to this trend, the Research and Extension department of Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte also uses the World Wide Web to divulge events, project notices, training courses, etc. However this department has been faced with some elements which hinder the operationalization of its activities. Thus, in order to provide an improvement in the execution of department’ tasks, this paper aims to develop a prototype to manage projects on campus. According to users, the work may be considered satisfactory because meets their main requirements. 2013-01-15T00:00:00Z
