1. Real conditionals (단순 조건절 = 현재 조건절)
Real conditional sentences are used to talk about possible situations and their results. The if-clause states a possible event or condition.
The main clause states the result of that event. Notice the use of a comma when the if-clause comes first.
1. Introduction:
1.1 What is Global Warming?
Global warming is the rise in the average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's mean surface temperature has increased by about 0.8 °°C(1.4°°F), with about two-thirds of the increase occurring since 1980. Warming of the climate system is u
Tidal stream generators (TSGs) make use of the kinetic energy of moving water to power turbines, in a similar way to wind turbines that use moving air.
A TSG is a machine that extracts energy from moving masses of water, or tides.
Energy can be captured from tidal streams using two methods,
Tidal fences and Tidal turbines.
Dynamic tidal power or DTP is a new an

There are many contributors who are dealing with environmental issues and car industry is one of industries that the mostly challenged by forces in the world. Particularly, cars take part significantly in air pollution because of the fuel emissions.
real goals that GE strives to reach through continuous investment in the following four commitments.
Commitment #1: Double Investment in R&D
In 2008, GE invested $1.4 billion in cleaner technology research and development (R&D), drawing closer to their pledge to invest $1.5 billion on Ecomagination R&D by 2010. R&D investment has reached a total of more than $4 billion since the p

②White emission using mixtures of CdSe quantum dots and PMMA as a phosphor
This paper explain WLED that have mixture stucture (one single chip(emit blue light) and cdse/PMMA quantum dots). CdSe quantum dots are synthesized by the wet chemical method using CdO and Se powder as precursor. And they control the size of quantum dot and mix the phospors(PMMA).
These quantum dots have three differe

Countries such as China have shown they are willing to spend in excess of £65 billion to boost their tourist industry.

By encouraging tourism there is the potential to create a real positive economic impact, a particularly desirable idea considering the fragile global economic state.

위기 뒤에는 기회가 찾아온다고 했던가.
산업혁명의 기원에는 우리가 알지 미처 알지 못한 숨겨진 사실이 있었다. 인류에게 유래 없는 물질적 풍요를 안겨준 산업혁명, 그 산업혁명을 촉진하게 된 계기는 16세기 중엽 이후의 목재 자원의 고갈이었다. 이 연료 위기를 극복하
