Positive Effects of Volcanos Volcanic activity has many positive impacts on both the natural physical environment and on socio-economic activity. Positive impacts include the creation of new land‚ the creation of valuable natural minerals and ores‚ and the enhancement of countries’ tourism potential. Creation of new land: Volcanic activity can result in the creation of new land‚ when material from within the earth’s crust is ejected in the form of molten liquid‚ then cools and solidifies to created

The height of a column of fluid necessary to develop a specific pressure. The pressure of water at a given point in a pipe arising from the pressure in it. b. Total Discharge Head Total discharge head refers to the actual physical difference in height between the liquid level in the pit and the highest point of the discharge pipe or water level in

courses offered by an educational institution”. In the world of education‚ do extracurricular activities still matter? Well‚ they are definitely a way to escape boredom as they strive to challenge an individual to do something new by overloading or filling up his schedule. And in truth‚ there are some anecdotes on different individuals cracking under pressure due to their participation in these activities. However‚ they cannot compare to the countless rewards that these ventures have to offer. After

The effects of the school activities to the learning achievement of the selected fourth year students of Liceo de San Pedro Academic Year 2009-2010. School activities are those sponsored by and usually held at school but that are not part of the academic curriculum. They often involve some time commitment outside of the regular school day. A school activity serves as a break of the students from their lessons. School activities include both extracurricular and co-curricular activities. School

I. Lubricants selection and Application A.Viscosity Most important property of any lubricant is viscosity. A common mistake when selecting a grease is to confuse the grease consistency with the base oil viscosity. Because the majority of grease-lubricated applications are element bearings‚ one should consider viscosity selection for those applications. While most would not use an EP 220 gear oil for an oil-lubricated electric motor bearing‚ many people will use a grease containing that same oil

We are studying the effect of pH on catalase activity. Catalase by scavenging hydrogen peroxide to water and oxygen is an important enzyme of cell defense mechanisms against oxidative stress in all living organisms (Dat et al.‚ 2003). Cells use catalase because it is the most efficient enzyme as an antioxidative enzyme which lowers hydrogen peroxide or superoxide to accumulate to toxic levels in plant growth (Bowler et al. 1992). The formula that involves catalase as the enzyme is . pH is a measure

Fluid intelligence reflects information processing capabilities‚ reasoning‚ and memory. It is used to evolve the ability to think clearly. For instance‚ a person who is asked to arrange a series of letters according to some rule or to memorize a set of numbers uses fluid intelligence. Although it is defined as the inmate and learning caoacity of all individuals. To my knowledge fluid intelligence is used in so many ways‚ throughout the country. It normally affect’s children during childhood and
