Fuel cell
device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent
Principle
1.Anode : Ionization of H2
H2 → 2H++2e-
2.Movement of H+&e- from anode to cathode
· H+ : along the electrolyte
· e- : along the electrical load
3. Cathode : chemical reaction of O2- &2H+
O2-+2H+ → H2
and recycled to extraction system because most of solvent is expensive.
2. 3. Compounding
PHB obtained in the extraction process as shape of powder. This powder is transformed into pellets in an extruder to make final product. At the same time, nucleating agents and plasticizers are added to improve processability or mechanical properties.

BDNF hypothesis, which came from support of many studies, states about the ways stress reduces BDNF-mediated signaling in hippocampus. On the other hand, sustained treatment of anti-depressant shows increase of BDNF-mediated signaling. Similar changes have been obse

Economic Issues
-U.S. inflation rates in 2003 remained low.
-European economies, which represent 30 percent of world GDP, are a mixed bag. Europe in general has experienced three years of slow growth with some recent
income for 2007 was primarily
the result of higher revenue. However, our results for
the year were adversely impacted by a significant
increase in fuel prices and a special non-cash charge of
$104 million to increase our deferred tax asset valuation allowance. The increase in fuel prices in recent years has caused most U.S. domestic carriers to reduce capacity
and increase fares.”
Form new intermediaries
- linking consumers to products
An important intermediary role
: summarize, aggregate extensive product
information and filter.
: reduce the information consumers.
Isolate consumers from vendors
: the information can be kept private
Reduce the information load on consumers
A new breed of intermediaries
