1. Converting a Conventional Vehicle into an Electric Vehicle (EV)
Abstract The electric vehicle (EV) is not a recent invention. Between the end of the XIX century and the beginning of the XX century, most motor vehicles were electric, due to their superior reliability and cleanliness, compared to that of vehicles driven by internal combustion engines (ICE). However, with the development of ICEs and the reduction of their p

2. Schizophrenia TreAtment with electRic Transcranial Stimulation (STARTS): design, rationale and objectives of a randomized, double-blinded, sham-controlled trial
Resumo Introdução A esquizofrenia é um transtorno mental grave. Embora alguns medicamentos antipsicóticos tenham demonstrado eficácia no tratamento de sintomas positivos, não há tratamento amplamente reconhecido para sintomas negativos, o que pode causar sofrimento e prejuízo significativos para pacientes com esquizofrenia. Aqui descrevemos a funda

3. Influence of different compacting methods on concrete compressive strength
ABSTRACT Adequate compacting is an important stage contributing for the durability and final quality of concrete structures. The two main ways of compacting concrete are: manual and mechanical (immersion vibrator). This paper has the goal of verifying the influence of those two compacting methods on the compressive strength of concrete from long term data. I

4. Application of methodology for the adequacy of the electrical motor's power sizing: permanent and transient analysis
Abstract The suitability of the motive force contributes to the efficient use of electrical energy. On the other hand, the inadequate size of electric motors is directly connected to increased investment and running costs. This article presents the theory and mainly the application of a methodology for the adequacy of the motive power. The research was condu

5. A forced running wheel system with a microcontroller that provides high-intensity exercise training in an animal ischemic stroke model
We developed a forced non-electric-shock running wheel (FNESRW) system that provides rats with high-intensity exercise training using automatic exercise training patterns that are controlled by a microcontroller. The proposed system successfully makes a breakthrough in the traditional motorized running wheel to allow rats to perform high-intensity training a

6. Acúmulo de cargas elétricas em propelente sólido compósito com matriz de polibutadieno líquido hidroxilado
Composite solid propellants prepared with HTPB prepolymer - Hydroxyl Terminated Polybutadiene, AP - Ammonium Perchlorate as oxidizer and aluminum particles as an additive metal, have characteristics of high electrical resistivity. The loading process of the polymer matrix did not obtain homogeneity, resulting in clusters, mainly of metal particles. The effec

9. MicrogeraÃÃo de energia elÃtrica com gÃs de sÃntese de um gaseificador concorrente utilizando ItaÃba mazilaurus / Microgeneration of electricity with syngas from a downtraft gasifier using ItaÃba mazilaurus
The use of biomass as energy source is one of the most promising, because it contributes to reduce emissions of carbon dioxide in the atmosphere and allow the decentralized energy generation. Gasification is a technology of processing biomass energy into a gaseous biofuel of low calorific value. The gas can be used in Otto cycle engine for power generation i
