Over the years, cities have undergone transformations that, invariably, overload and even compromise the functioning of an energy matrix dependent on increasingly scarce resources. The high demand for energy has challenged stakeholders to invest in more sustainable alternatives, such as bioenergy, which, in addition, helps to reduce the pressure for finite resources, enable the energy recovery of waste and contribute to the mitigation of carbon emissions. For these improvements to be successful, stakeholders need specific technological strategies, requiring tools, methods and solutions that support the decision-making process. In this perspective, the current work aimed to develop a framework optimizing the evaluation of waste bioenergy projects through the application of algorithms. Therefore, a literature review was carried out to select the algorithms and identify the sectors/areas and stages in which they are applied. These algorithms were then grouped into two sequential phases. The first targeted the evaluation of region, based on the type and supply of biomass, while the second sought to optimize aspects related to infrastructure and logistics. Both phases were concluded with the application of multi-criteria methods, thus, identifying the areas/regions with the greatest potential for implementing bioenergy projects. In general, it was observed that there are different algorithms and multi-criteria analysis methods that can be suitable in bioenergy projects. They were used to identify and select the regions with the greatest potential for bioenergy plant implementation, focusing on the type, quantity and perpetuity of biomass supply, to assess the operational efficiency of machines, equipment, processes and to optimize the logistics chain, especially the collection and transport of biomass. Thus, the joint work between the use of algorithms and multi-criteria decision methods provides greater assertiveness in choices, helping to identify the most viable projects and mitigating risks and uncertainties for decision-makers.

This study aims to report a rare case of mixed gonadal dysgenesis with mosaicism pattern 45 X0 / 46, X, +mar 1/ 46, X, +mar 2. Patient referred to the pediatric urology service with 2 months of age. Right after the baby was born it was not possible do determine the baby's gender. The karyotype was inconclusive: 45, X0. Contrast genitography and uretrocystogram showed a single perineal orifice below the micropenis and between the bifid scrotum, opacification of the bladder with male aspect urethra during urination and short penile urethra. There was also opacification of the posterior vaginal cavity with low junction to the posterior urethra and a linear opacity image suggesting uterine canal. Laparoscopy revealed bilateral gonadal bands and spermatic elements entering the inguinal canal. Müllerian derivatives were absent. Gonadal biopsy was performed and concluded that these were abnormal infantile testes. Microarray testing took a few months and resulted in: 45 X0 / 46, X, +mar 1/ 46, X, +mar 2. Patient was kept on topic androstenedione for 6 months and then underwent penoscrotal hypospadias correction. Mosaic chromosomal pattern is a rare condition that can present with a wide variety of phenotypes. Early recognition has important implications on these patients' social and psychological life and also for their proper management.

Em consequência dos diversos problemas ambientais enfrentados em todo o mundo, depara-se com a necessidade de desenvolver um ambiente em que haja uma constante harmonia entre a produção/consumo de bens materiais e o meio ambiente. Nesse contexto, a Economia Circular surge como um conceito inovador que visa a desenvolver estratégias para mitigar os efeitos gerados pela antiga economia linear a partir da criação de um ecossistema mais sustentável. O objetivo deste trabalho é realizar um levantamento prospectivo nas bases tecnológicas de patentes EPO, USPTO e INPI, baseado em palavras-chave associadas aos métodos e às técnicas da Economia Circular e sua aplicabilidade. Como resultado, foram encontradas 1.277 patentes em diversas áreas de estudos e de diferentes países. Posteriormente, observou-se um crescimento relevante na concessão de novas patentes ao longo dos últimos anos, motivado pela importância da criação de novas tecnologias que têm como intuito solucionar problemas ambientais que ocorrem em áreas ainda mais específicas.
