The genus Trichoderma comprises more than 400 species of fungi distributed across all ecosystems worldwide. Fungi of this genus have been widely reported to produce metabolites with various activities, which have been used in diverse areas such as in pest biocontrol, resistance induction in plants, and production of biomolecules of biotechnological interest. This review aims to provide an overview of the main species of Trichoderma that produce biomolecules with activities that are useful in the biotechnological field, emphasizing metabolites with antibacterial and antitumor activity.

Heat Transfer Coefficients are extremely important for design and control of thermal processes involving the convection mechanism. Experimental evaluation of the film coefficients is not simple because such parameters depend on the system geometry, flow regime and physicochemical properties of the fluid. Thus, an interesting alternative for estimating the convective heat transfer coefficient is to apply CFD techniques to solve the transport equations numerically.

Hydrogen has important physicochemical and combustion properties that can be used to improve performance and reduce pollutant emissions by motor vehicles. However, storage difficulties can limit its use in internal combustion engines. So, in this research, hydrogen gas was produced and consumed immediately in order to eliminate the need for a storage device. First, a cell for alkaline water electrolysis was built to produce hydrogen and use it as a complementary fuel in an internal combustion engine.

Introdução: OSGOOD SCHLATTER e Osteocondrite Dissecante são patologias que geram alterações funcionais e anatômicas podendo gerar fragilidades morfológicas do sistema musculoesquelético. Sendo assim o trabalho interdisciplinar da biomecânica e interevenção da fisioterapia são fundamentais para analisar os mecanismos de lesão no decurso do surto de crescimento maturacional, ao passo de avaliar e tratar as manifestaões oesteomusculares e limitações funcionais destas patologias.

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.
