1. MÉTODOS PARA CORREÇÃO DAS DISTORÇÕES DA FORMA DE ONDA SECUNDÁRIA CAUSADAS PELA SATURAÇÃO DE TRANSFORMADORES DE CORRENTE PARA SERVIÇO DE PROTEÇÃO / METHODS FOR CORRECTION OF SECONDARY WAVEFORM DISTORTIONS CAUSED BY SATURATION OF CURRENT TRANSFORMERS FOR PROTECTIVE RELAYING PURPOSES
This work aims to evaluate the performance of some methods used to detect and correct the distorted portions of the secondary current signal waveform, which occur due to the core saturation of current transformers. Such methods are presented didactically divided among techniques existing in the specialized literature and new methodologies proposed. Involving

2. Borrelia burgdorferi swims with a planar waveform similar to that of eukaryotic flagella.
Borrelia burgdorferi is a motile spirochete with multiple internal periplasmic flagella (PFs) attached near each end of the cell cylinder; these PFs overlap in the cell center. We analyzed the shape and motion of wild type and PF-deficient mutants using both photomicrography and video microscopy. We found that swimming cells resembled the dynamic movements o
