Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma

♦Introduction
- What is benefits
Benefits is selected to the worker in a variety of item that designed to corporate. Workers assigned to them in the welfare budget and the rating based on their lifestyle and welfare items, and they can select the level of benefits.
Based on the selection of staff welfare and benefits of the information is determines the level of that. That was reflect
preservation technologies. Various modern technologies are applied to inhibit the growth of micro-organisms in food product as various food-spoilage micro-organisms are exit. Consequently, the techniques are so complicated and diverse to state in one paragraph. This report divides the methods into several categories, physical, biological, and chemical, and introduces each technology briefly.
High-temperature decomposition
High-temperature splitting of water occurs at about 3000 °C. At this temperature, 10% of the water is decomposed and the remaining 90% can be recycled. To reduce the temperature, other processes for high temperature splitting of water have been suggested:
▸Thermo-chemical cycles.
▸Hybrid systems coupling thermal decomposition and electrolytic
I. Introduction
1. The significance of the Ricardian Model
The modern economic trade theory was originated from the advocator of ‘absolute advantage’, Adam Smith. According to the theory of ‘absolute advantage’, each country specializes in the product of its absolute advantage in productivity. The theory of ‘absolute advantage’ was accepted as intuitively correct during that time

mediator release via sirtuin-NF-κB RelA/p65 interaction. Cigarette smoke decreased sirtuin levels and caused posttranslational modification by reactive aldehydes/reactive oxygen species/RNS, thereby disrupting SIRT1-RelA/p65 complex via phosphorylation (P) and acetylation (Ac) of RelA/p65. This leads to increased release of pro-inflammatory mediators. RNS, reactive nitrogen species.
modification method
Introduce some specific element or functional group onto the surface of materials.
Specific functional groups provide special chemical reactivity and varying physical properties for surface
A variety of molecules such as protein, peptide and gelatin, have been successfully bound on surface of materials.
