The vehicles relied on fossil fuels are rapidly being replaced by electric and plug-in hybrid vehicles. But these types of vehicles are still faced with the problem of energy availability. The abundance of solar radiation and its use as the power source in electric vehicles is a necessary condition for environmental pollution limitation. In this study, the authors present photovoltaic systems used as an electricity supply for E-Smart electric vehicles. E-Smart is an electric vehicle obtained through conversion, of a Smart ForTwo City vehicle, from the internal combustion propulsion system to a system that uses a three-phase asynchronous motor supplied from a pack of 32 batteries of LiFePO4 type.
Background
Osteoporosis is a metabolic disease widely spread both worldwide and in our country, being a major public health problem, with serious social and psychological consequences, by the huge costs involved, as well as by its high morbidity.
Aim
We intend to prove the effectiveness of using physical exercise for improving static and dynamic balance in patients with osteoporosis.
Methods
Our research includes 8 women aged between 50 and 70 years, diagnosed with postmenopausal osteoporosis. The patients were evaluated before and one month after the physical exercise program, using the “Timed Up and Go” Test and the Berg Balance Scale.
Results
All patients included in this research experienced improvements in postural stability, static and dynamic balance.
Conclusions
After performing a one-month program of specific physical exercise, with a frequency of 3-4 times a week, the risk of falls decreases, increasing the static and dynamic balance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
