Able to dissipate limited amount of heat flux.
Lower coefficient of performance than vapor-compression systems.
Relegated to low heat flux applications.
More total heat to remove than without a TEC.

Propensity to consume food & beverage
□As an income level is being inclined, consumption for food expends as well.
□ Engel’s coefficient is diminishing with income upsurge but, absolute quantity of food e
Ⅰ. Introduction
1) Location
Russia is located in the north Eurasia continent (Far East Asia ~ Europe). Russia is the largest country in the world which is about 1/8 of the world’s land area. Because of this huge territory, there is an 11-hour time difference between East and West.
2) Climate
The huge territory of Russia also makes a various climate zone. Basically, Russia has continental
3. Requirements of EUV resist
EUV is highly absorbed by all materials, even EUV optical components inside the lithography tool are susceptible to damage, mainly manifest as observable ablation. Such damage that is associated with the high-energy process of generating EUV radiation is a new concern specific to EUV lithography .
EUVL's shorter wavelength also increases flare, resulting in less
2. Objective
1) To investigate of solid-liquid mixture flow characteristics in a slim hole annulus
2) Effect of pipe rotation, fluid property, annulus inclination on the particle transport velocity, transport efficiency and pressure drop
3. Theoretical background
3.1 Reynolds number
Reynolds number can be defined for a number of different situations where a fluid is in relativ
Assumption

△P doesn’t change nearly
When (A₂/A₁) is smaller than 0.1.
☞ Even though (A₂/A₁) is smaller than 0.1,
actual effect is not remarkable.

5.2 Drug Delivery System
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
(4) Double patterning
The double patterning is divided into four parts, leading with wafer requirements and then two sets of lithographic requirements (Generic Pitch Splitting - Double Patterning Requirements Driven by MPU metal Half-Pitch and Generic Spacer Patterning Requirements - Driven by Flash). The lithography requirements are different for each process; the requirements for pitch splitti
