Systematic review in financialization politics: The role of corporate governanc...

This review seeks to synthesize empirical findings on financialization policies and provide answers to two questions: (1) What relationship exists between Financialization and Corporate Governance? (2) Is there any relationship between financialization and CEO compensation/remuneration systems? A group of 38 scientific articles was selected using the methodological protocols ProKnow-C and Methodi Ordinatio. Bas...

The sequences of the hyperbolic k-Perrin and k-Leonardo quaternions

In this article, hyperbolic k-Perrin and k-Leonardo quaternions are defined. In this sense, bulletin, are evaluated as sequences of k-Perrin and k-Leornado, their respective quaternions and thus the definition of hyperbolic quaternions. Thus, there are some algebraic properties around numbers, generating function, Binet's formula and properties inherent to these numbers.

Radiation-Hardened Bandgap Voltage and Current Reference for Space Applications...

This paper describes a radiation-hardened bandgap voltage reference (BGR) for space applications. The BGR has a second-order curvature compensation and can deliver a stable output voltage and current for N-type and P-type loads through internal resistors or, optionally, through an external precision resistor. The circuit includes three 8-bit trimming resistive ladders for post-fabrication calibration of the tem...

Architectural Design for Heartbeat Detection Circuits using Verilog-A Behaviora...

This work presents a study of two analog frontend circuit architectures for heartbeat detection. Both circuits present an amplification block as the first stage, followed by a band-pass filter. In the first, the heartbeat detection is done using an adaptive threshold based on pulse-width, whereas the heartbeat detection in the second is done using a sample and hold to find the maximum and minimum peak of each b...

Using quantitative methodologies to conduct a systematic review in social scien...

The work presented here arises in the context of a larger work, which is related to the need of carrying out a survey of possible gaps in the literature on the subject of financialization within the scope of Corporate Governance, followed by a Systematic Review of the topic. Thus, using the Vos Viewer tool and two scientific methodologies, that have gained prominence in recent years - ProKnow-C Method and Ordin...

Formação de professores para uma educação diferenciada

Este texto explora as potencialidades de um currículo contextualizado com as culturas locais – etnocurrículo – e o papel do professor como mediador cultural na construção de uma educação diferenciada que permita que a escola seja efetivamente para todos e para todas.

Entre a coexistência e a convivência: Imigração portuguesa e estratégias de med...

Efficiency improvement of vehicles using temperature controlled exhaust thermoe...

One of the main obstacles for the use of thermoelectric generators (TEGs) in vehicles is the highly variable thermal loads typical of driving cycles. Under these conditions it will be virtually impossible for a conventional heat exchanger to avoid both thermal dilution under low thermal loads and TEG overheating under high thermal loads. The authors have been exploring an original heat exchanger concept able to...

Compact automotive thermoelectric generator with embedded heat pipes for therma...

Currently, the automotive industry faces challenges to implement solutions that provide reductions in energy consumption, pollutants and greenhouse-gas (GHG) emissions. Exhaust heat recovery employing Thermoelectric generators (TEGs) enables the direct conversion of heat into electric energy without moving parts and little to no maintenance. On-board electrical production is especially useful given the growing ...
