13. Effects of Resistance Exercise with Instability on Neurocognitive Functions (REI STUDY): Study Protocol for a Proof-of-Concept Clinical Trial in Older Adults with Subjective Cognitive Complaints
Abstract Aim: Resistance exercise (RE) is a widely accepted strategy to counteract the effects of aging and chronic diseases on health-related outcomes. Studies have been suggested that RE improves brain and cognitive health. RE with unstable devices (REI) is a neuromotor complexity strategy with the potential to improve strength, power, and balance in onde

17. Development and Characterization of PbI2 Nanoparticles for all Solid-State Flexible Supercapacitor Purposes
The development and utilization of new energy sources has been extensively studied in the world. Here, we report the development of flexible self-supported metal-free electrodes based on non-oxidized graphene multilayer (MLG) paper containing the lead iodide nanoparticles (PbI2-NPs). The PbI2-NPs was obtained and characterized by X-ray diffraction (XDR) and

20. Public Policy Instruments and Their Impact: From Analogue to Electronic Government in the Bus Services of São Paulo
This article deals with the relations between public policy instruments and production practices of objects related to government action. It demonstrates that the materiality of the instruments built to make a public policy object legible to its operators has independent effects on the relations among private operators, bureaucrats, and the public sector. Ba

23. HARVESTING FRUITS USING A MOBILE PLATFORM: A CASE STUDY APPLIED TO CITRUS
ABSTRACT Harvesting fruits and vegetables has been a challenge. Mobile platforms for harvesting vegetables and fruits have been used, but with some limitations, such as their applicability for a certain time of the year and for a specific crop. A mobile platform was initially developed for harvesting fresh market tomatoes, mainly staked in Brazil. However, a

24. Compensation technique for environmental and light source power variations applied in a polymer optical fiber curvature sensor for wearable devices
Abstract Introduction Polymer optical fibers (POF) are lightweight, present high elastic strain limits, fracture toughness, flexibility in bend, and are not influenced by electromagnetic fields. These characteristics enable the application of POF as curvature sensor and can overcome the limitations of the conventional technologies, especially for wearable a
