Background: The posterior cerebral artery (PCA) is a vessel of the Circle of Willis. Variations are observed in the first segments of the PCA and its branches, especially in the thalamoperforating arteries (TPAs) and in the artery of Percheron (AP). Anatomical presentation of these arteries is of relevant clinical importance for safer neurosurgical approaches. Objective: To identify the most frequent PCA and TPA patterns and the morphometry of P1 and P2 branches in human brains from the Northeastern region of Brazil. Methods: Specimens of human cadavers from Northeast Brazil were isolated.

In the 19th century, Gratiolet created the term plis de passage, which was mapped by the neurosurgeon Jean Regis to describe gyri that were interconnected and anatomically covered by main sulci. Besides, Cunningham characterized the plis de passage, which binds the precentral gyrus, associated to the hand´s primary motor area, and the postcentral gyrus, associated to the hand´s somatosensory area, having become a subject of interest with the advent of imaging tests.

Innovation in companies is directly related to investment in Research and Development and to the formalization of their Intellectual Property. At the same time, it also tends to be related to organizational performance and value in the market. In view of this, this work consists of a systematic review of the international literature regarding the relationship between intellectual property (patents, brands, software, among others), an important indicator of innovation, and its effects on organizational performance. Scopus and Web of Science databases were consulted.

A paracoccidioidomicose (PCM) configura-se uma importante micose sistêmica, de grande representatividade no Brasil. Embora seja um país endêmico para a doença, observa-se ainda grande dificuldade para diagnóstico precoce, tratamento oportuno e acompanhamento adequado dos indivíduos acometidos. O atraso no diagnóstico da doença além de permitir o agravamento da mesma, pode ainda levar a tratamentos equivocados, gerando prejuízos aos indivíduos acometidos, e aos serviços de saúde.

Une prospection médicale récente sur la trypanosomose humaine africaine (THA) dans des sites d'orpaillage au Sud-Ouest du Burkina Faso, a mis en évidence la présence de mouches tsé-tsé infectées et des populations venant de la Côte d'Ivoire et de la Guinée, les deux pays d'Afrique de l'Ouest les plus affectés par cette maladie. Cet état de fait, montre un risque de réémergence de cette maladie.

Esse artigo trata-se de uma metodologia que pode complementar o plano curricular de curso (PPC) e esse trabalho está sendo aplicada no curso de Engenharia Civil da Universidade do Estado de Minas Gerais unidade Divinópolis. Essa metodologia é chamada de Trabalho Integralizador Multidisciplinar (TIM). O TIM é um projeto de extensão e é trabalhado com os alunos a cada nova disciplina a cada semestre.

This paper proposes a method based on adapted Flower Pollination Algorithm (FPA) and the use of Sensitivity Analysis (SA) to determine the optimal allocation and sizing of Distributed Generation (DG) in radial distribution Systems. The most suitable set of buses for allocation is defined through SA at an initial stage. The FPA adaptation consists in splitting the search process between the allocation and sizing phases in order to increase the search efficiency.

The aim of the study is to explore the relevance of the Physical EducationUniversity programme to the needs of women teachers in Oman through an evaluation of current practice. This study revisited studies and literature done by the author in the same area and emphasis will be placed on contextualising the programme and currently in terms of the overall educational goals of the Sultanate and the Sultan Qaboos University (SQU) as: Al Sinani (2013); Benn, & Jawad, Al-Sinani.(2014); Al-Sinani & Benn (2010); SQU 1992.

O atual momento de pandemia, provocado pelo vírus Sars-Cov-2, no Brasil trouxe à tona alguns dos problemas crônicos que a sociedade brasileira, principalmente a menos favorecida, sempre vivenciava no seu dia a dia. Uma destas situações é a péssima qualidade do transporte coletivo urbano. Sabendo que o investimento neste setor envolve cifras multimilionárias, gestores públicos e agentes privados buscam desenvolver formas de aliviar o sofrimento que a população usuária do transporte público perfaz, diariamente, para se deslocar até o seu trabalho, para estudar ou mesmo para lazer.
