RESUMO
The future of sustainable energy is bright, with continued advancements in technology and growing global awareness of the need to transition to renewable energy sources to combat future challenges. The electrical vehicle is new hope for the automobile industry where the deduction of carbon emission is the priority. The increasing level of carbon emission may be harmful to the environment and society. A qualitative exploration of sustainable energy and its role in electrical vehicles are other aspects of the study where green energy is another variable. The research design used in the study is exploratory in nature and covers the different dimensions of sustainable energy. Production of the batteries is also following certain protocols of natural sustainability and emission. This study will enunciate the role of sustainable energy sources under the aspects of green energy. Economic benets are also associated with the dened issue. Resultants are qualitative in nature where the crux of the previous study had been discussed. This study has concluded
RESUMO
The effects of global warming and climate change are happening at a faster rate than expected, and they are going to get worse. Global climate change has already started to show the effects on environment—fast melting glaciers, accelerated sea level rise and base shifting of native flora and fauna. There has been an increase in temperature globally with a few countries already showing intense heat waves and extreme cold temperatures. The interrelation between dentistry, environmental impact and human health is still in its nascent stage, but studies in medicine show that the healthcare industry contributes to greenhouse gas emissions and climate change, poor air quality, food and water insecurity, extreme weather events and vector?borne illnesses. The concept of eco?friendly dentistry has evolved in this context for providing environmentally feasible dental solutions. Paediatric dentistry is no exception. The concept of prevention has to be promoted more in paediatric dentistry to provide a positive impact on environment. The prevention of oral diseases will lead to less travel to paediatric dental clinics, less use of dental materials, lesser energy usage, minimal use of single?use plastics and less use of nitrous oxide/general anaesthesia for behaviour management. The greenhouse gases have an effect on teeth of children in relation to early childhood caries (ECC). Here, we discuss the impact of climate change on paediatric dentistry and what changes can be made to provide environment?friendly solutions
RESUMO
The development and present situation of high power and luminous flux LED is introduced. The feasibility of high luminous flux LED in the field surgery illumination is analyzed in detail. Then the realizable plans are discussed separately from device, driving circuit, optical system and mechanical system.
