Many coal miners breathe in the pollutants of coal dust and one of the effects of coal mining is the development of black lung disease. It is caused by long-term subjection to coal dust. Dust particles collect in the tissues of the lungs and it results in injury to the lungs. Besides creating critical health problems for coal miners, there are also serious health problems that can occur outside of the mine and above ground. Those who live relatively close…...

Building Energy Consumption Evaluation Methods
Words • 512
Pages • 3
Several methods and tools have been developed over the past two decades aimed to evaluate energy consumption in buildings; in response to the implementation of regulations on energy use in buildings. Evaluation of energy performance for buildings has been carried out using benchmarks. These benchmarks are usually as a result of building audits and surveys to establish what is typically accessible or extant conditions (Vaezi-Nejad, et al., 2003) (Krarti, 2012). The overall understanding is that if the current situation is…...

Analysing the energy use in buildings can be as complex as the construction of the building itself. In order to lessen the impact on energy on the environment, building energy performance assessment is often undertaken to determine its performance in relation to other buildings and the built environment in general (Douglas, 1996). The performance result is been used to define what is regarded as typical. Hence, forms the benchmark upon which improved performance is pursued. The methods of assessment have…...

Newton’s Law of Motion helps people predict how an object with rise or fall. To predict motion, you can use a ball or a piece of paper. If you drop a ball from 1,000 ft. will it bounce higher than how far it fell, or will it only bounce half way (500ft)? Newton’s first Law of Motion states that an object at rest will stay at rest, thus, for example, if the human body was to stay still instead of…...
