The consumption of electricity grows as technology advances, as this, almost entirely depends on the power of some energy source, the increase in this consumption causes positive impacts, but also negative one of them is due to the high cost of these resources , the reduction of resources destined to education in Brazil makes institutions look for strategies to reduce expenses and one is, to be able to use efficiency in the consumption of electric energy. This work aims to reduce electricity consumption, increase the duration of climate control devices and improve thermal comfort.

Introduction: ESRD is a silent killer which largely affects the quality of life. Hemodialysis is a main treatment modality for these patients. It leads to various complications like fatigueand alterations in physiological parameters. Intradialytic Leg Ergometry Exercise is an effective approach to reduce fatigue and for improving physiological parameters. Methods: A quasi-experimental design was used to conduct the study.

Objetivo: Analisar as patentes de tecnologias no âmbito da ética. Materiais e métodos: A revisão bibliográfica ocorreu entre junho a julho de 2021, na base de dados Web Of Science (Derwent Innovations Index). Foram encontradas58 patentes, que a partir dos critérios de seleção foram incluídas somente 12 para análise. Resultados: Dentre as 12 patentes, predominaramas tecnologias desenvolvidas na Índia registradas em 2021. Dentre aInternational patent classification, prevaleceu a categoria G06 (Informática; Cálculo ou contagem) na área de pesquisa da ciência da computação e engenharia.

The Peripherally Inserted Central Catheter (PICC) has become a relevant device, so it is pertinent to be empowered with the literary knowledge produced in order to enable the best practice. The aim of this study was identify, in national and international publications, the current knowledge about PICC and Bloodstream Infections in the neonatal population. This is an integrative review. Data collection was performed through electronic Search in the following databases: LILACS, MEDLINE-PubMed, SciELO, Science direct (ELSEVIER) and Cochrane.

The purpose of this paper is to analyse the governance mechanisms adopted by an intermediary company to successfully manage new product development (NPD) in a triadic relationshipformed by two Brazilian companies and a Chinese one. Qualitative research was conducted through a particular case study in the context of the offshore petroleum industry. The analysis was developed during and after data collection, using content analysis (Bardin, 2000) with a priori categorization adapted from Ateş, Van den Ende and Ianniello (2015).

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.

Objective: To characterize videos with content supporting the practice of physical exercises performed at home during the quarantine period, available on the YouTube™ platform. Method: The search was performed using the terms: “Training Quarantine”, “Training Coronavirus”, and “Training COVID”, identifying videos published between March 20th and June 30th, 2020. Results: A total of 386 videos were analyzed; in March and April, there were a greater number of videos published (34.72% and 40.93%, respectively).

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.

Humeral condylar fractures are relatively common in dogs and are most often associated with low-energy trauma, mainly affecting young animals. Anatomical reduction and rigid stabilization are mandatory to correct these types of articular fractures and achieve the main goals as early return of limb function, pain-free elbow movement, and prevent or at least reduce degenerative joint disease.
