Integração da abordagem Domain-Driven Design e de técnica Behaviour-Driven Development no desenvolvimento de aplicações web
(Universidade Federal de São Carlos, 2015-06-01) Santos, Eloisa Cristina Silva; Beder, Delano Medeiros; https://lattes.cnpq.br/5845245549777383; https://lattes.cnpq.br/9708266485563159
The agile methods of software development have emerged as an alternative to traditional approaches, to spend less time on documentation and more time with solving problems interactively and iteratively. In this context, the development approach Domain Driven Design (DDD) is a way of developing software in which the application design process is guided by a domain model. In conjunction with the DDD development approach, the existence of tests during the implementation of an application is required to ensure quality. Objective: This work aims to study the agile development approach Domain-Driven Design (DDD) and the software test techniques Test-Driven Development (TDD) and Behaviour-Driven Development (BDD). A case study was built to exemplify the integration of each test technique with DDD. The case study was developed with the support of the Apache Isis framework, from a well-defined domain model. Methodology: Based on the literature, the concepts of the DDD development approach and of the TDD and BDD test techniques, that provided the comparison between the techniques, and later, the implementation to illustrate this research, were extracted. The Apache Isis framework was used in this work because it allows develop DDD applications quickly. During the development of the sample system of this work, the possibility of creating an automatic generator tests and scenarios for BDD was noted. Results: A case study was created using the concepts of DDD and tests, with TDD and BDD. Furthermore, a prototype of tests and scenarios generator for software projects that use DDD, through the Apache Isis framework and tests using BDD, was developed. Conclusions: The combination of test techniques mentioned with DDD aim to boosting the development of applications, since DDD is not associate with any test technique. Writing scenarios with ubiquitous language is a great advantage to integrate DDD and BDD, because it allows a clear understanding for all involved in the project. Moreover, the creation of automatic generator speeds up the testing phase, and can detect errors that might go unnoticed or only be found as the project evolved.
Análise do processo de licenciamento ambiental brasileiro : o caso da mineração na serra do Gandarela
(Universidade Federal de São Carlos, 2015-06-01) Scatolini, Tiago Luis Castro; Vargas, Marcelo Coutinho; https://lattes.cnpq.br/8869018482093008; https://lattes.cnpq.br/8186976919547873
In recent years we have witnessed a permanent offensive sectors of the federal government and a very strong lobby of construction companies, mining companies and other companies interested in easing the environmental licensing standards. To this campaign added the deconstruction efforts of environmental legislation, undertaken by a joint forces located inside and outside of our legislatures. We emphasize in particular the limited participation of government institutions in the licensing process and advocate to be revised the current contracting model. Thus, this study will seek, in the light of network analysis theory and mutual comparison between the results and analysis of a brazilian environmental impact study and an academic research project for the same lithology, analyze the limits and contradictions of study brazilian environmental impact. The readback proposed aims to illustrate the possible existence of control by private interests in the studies of environmental impact as a result of their employment structure and governmental control. The analysis of the concession of natural areas operating license process is necessary given the importance of this study within the sustainable development theme, as well as their hiring process.
Desenvolvimento de plataformas baseadas em alumina e sílica nanoestruturadas com permanganato de potássio para uso como sensor colorimétrico de maturação de tomates cv. Pizzadoro
(Universidade Federal de São Carlos, 2015-06-01) Ohashi, Thaís Luri; Corrêa, Daniel Souza; https://lattes.cnpq.br/0461451015026948; Ferreira, Marcos David; https://lattes.cnpq.br/6652079760634274; https://lattes.cnpq.br/9695522410624850
Fruit quality is closely related to its physical characteristics, such as surface color and firmness, and are directly associated to the ethylene production (C2H4), which is the ripening hormone responsible for initiating the ripening process in fruits and vegetables. Consequently, the control of ethylene levels during postharvest can contribute to effectively extend vegetables shelf life. On the other hand, ripening indicators can be useful for the fruit production chain, because they provide information about product quality and may assist both the wholesaler and the consumer in the purchase decision steps. The aim of this study was to evaluate the functionality of platforms containing potassium permanganate (KMnO4) impregnated into inorganic nanoparticles (alumina and silica). Such platforms are aimed to be used as a colorimetric indicator (sensor) of ‘Pizzadoro’ tomato maturation, relating to the physicochemical changes in fruit quality. The use of nanoparticles (size between 1 and 100 nm) as carriers for KMnO4 makes ethylene oxidation more efficient, and allows for a superior color change, when compared to larger particles (above 100 nm). ‘Pizzadoro’ tomato fruits packed in polyethylene terephthalate packages (PET) containing adhesive with different concentrations of potassium permanganate (2,5%, 5%, 10%) impregnated into nanoparticles were maintained in storage chambers at 22 °C and 90% RH; and evaluated at every two days regarding: peel color, firmness, pH, soluble solids (ºBrix), titratable acidity, maturation index (ratio), as well as the gaseous composition of the package, except for fresh weight loss, which was carried out daily. The results indicated that potassium permanganate impregnated on nanoparticles were capable of absorbing and oxidizing ethylene efficiently, resulting in a gradual color change of the adhesives, from purple to brown. No significant differences in physical and chemical variables between treatments were observed, except for the fruit color parameters, suggesting delayed chlorophyll degradation and lycopene synthesis. Alumina nanoparticles impregnated with 5 and 10% of KMnO4 treatments showed a better performance as maturation indicators, presenting at least three adhesive color standards each. In sensory evaluation, tasters preferred the more intense red coloration fruits.
