With a great potential yet to be explored in Brazil, the grid-connected photovoltaic system, besides supplying the active power, can also contribute to improve the voltage level grid providing reactive power. Therefore, this work proposes to use a Grid-Co... see more

BACKGROUND: Strenuous non-regular exercise increases reactive oxygen species ROS level leading to an impaired balance between the endogenous antioxidant defence system and the free radicals production. Antioxidants intake can detoxify the peroxides produc... see more

Photodynamic therapy is a relatively new modality of cancer treatment in human and veterinary medicine. It uses a photosensitizing drug called photosensitizer; which in the presence of oxygen delivers reactive species (singlet oxygen and free radicals) up... see more

BACKGROUND: Patients with rheumatoid arthritis (RA) are at increased risk of cardiovascular disease (CVD). Lipid changes related to inflammation have been described in RA. Methotrexate (MTX) treatment is effective in controlling inflammation and decreasin... see more

Balance is what we call the ability to control the center of gravity over the support plane in a given environment (also defined as the ability to maintain a vertical position of the body without the help of another person and the ability of regaining&nbs... see more

A three-mass anti-resonance vibratory machine with a vibration exciter in the form of a passive auto-balancer has been analytically synthesized. In the vibratory machine, platforms 1 and 2 are visco-elastically attached to platform 3. Platform 3 is visco-... see more

To deal with extreme overvoltage scenarios with small probabilities in regional power grids, the traditional reactive power planning model requires a huge VAR compensator investment. Obviously, such a decision that makes a large investment to cope with a ... see more
