Abstract:Hydrogen has attracted people because of its cleanest, sustainable and renewable energy carrier with a remarkably reduced impact on the environment. In the future, hydrogen will replace the existing fossil fuels. Although it has number of advantages, it creates some difficulties in utilization. The most famous of them are production and storage. Carbon nanotubes (CNTs) …

The concept ofprotecting the skin from the harmful chemicals and bacteria has been used forcenturies. Ancient Egyptians used Olive Oil for the same purpose. Likewise,pastes of Zinc oxide were also applied on the skin to serve the same purpose.However, the earliest synthetic sunscreen was not synthesized before 19281. Theimportance of sunscreen was slightly heightened in …

Nuclear poweraccounted for just 11% of the worlds electricity production in 2014 yet nuclearreactors emit zero greenhouse gases and is around 8000 times more efficientthan fossil fuels, which generated 62% of the worlds electricity in 2014. Nuclearpower is also more reliable than other finite sources as there is enoughUranium to last 70-80 years. Power plants …

Investigation on the chlorine free HFC refrigerants which  have both advantages of HFC and HCFC. So the new study on blending of hydroflurocarbon takes place and new gases are formed such as R507A and R417a. All the  Blend mixtures are not the solution for the replacement  of existing refrigerant because GWP of the mixed refrigerant …

Solar energy is a very important renewable energy. Renewable energy is energy can get from renewable resources, which are replenished naturally after a certain period, like  sunlight, wind, rain, tides, waves, and geothermal heat. Solar energy is a highly appealing source of electricity because of its huge magnitude. Solar power is the transformation of solar …

When delinquents commit crime many people question whether the offender is physically or mentally abnormal, has any intelligence or a personality that reflects their abnormal behaviour. These psychological trait theories (approaches) are all linked to ones human behaviour (Wilson, Herrnstain 2007, p 33-34). Undoubtedly these theories reflect society’s common conception that most criminals lack intelligence, …
