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
Thermodynamics
Thermodynamic factors involve properties of the solute and the solvent. For example, If two molecules pass the thermodynamic factors, that is, if the thermodynamic factors indicate that they can dissolve with each other, then kinetic factors can take effect.
With stir, system(coffee cup) is given energy, and it causes internal energy to increase. Increased internal energy makes

5.2.1 Advantage of Nano-drug delivery system
By diagnosis, and for treatment, we need enhanced drug delivery system. Drug delivery system of these days is just eat and let it flow through the body. It is not good at efficiency. Because the digestive system sometimes digest and remove the drug before it reaches to the target.
For enhancing the efficiency of drug
● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for

Ⅰ. Need Of Alternative Energy
The need for alternative energy sources is getting urgent, hence the development of renewable energy is moving fast. Nationally and internationally various individuals and research companies are creating new and exciting energy systems. Some of these apparatus are great works and need improving for massive use. Politician's world-wide are dra

1) 원리 및 mechanism
분체의 물성을 강하게 지배하는 것은 입자의 크기 및 분포로서 이상적인 분쇄기는 분쇄용량이 크고, 분쇄생성물의 단위량당 동력소모가 작아야 하며, 원하는 단일입자 또는 입도분포를 가지는 생성물을 얻을 수 있어야 한다. 그 때문에 단립자의 파괴의 mechanism은 분쇄의 기본이다.
