1. Liberalization of Logistics Services.
In general, liberalization is a reduction in the direct involvement of the state in economic activity. And it is a reduction of state control of economic processes and activities like price, production directives, etc. Liberalization of logistics services is of course the same in the concept that it is relaxation of previous reg

We have a tendency to think CO2 is negative. Because of Global warming. But, In other face, CO2 is very useful to use.
As you can see we use Co2 in various ways. For example, in our lives, we can see Co2 in beverages, and in concert, we see Co2 in form of gas.
Anyway, Today I explain to you about this, Electrochemical reaction. We convert Co2 to other materials using electrochemical reaction.

It generates electricity inside a cell through reactions between a fuel and an oxidant, triggered in the presence of an electrolyte.
Fuel cells are direct energy conversion into electricity. So High electric conversion efficiency and carbon dioxide reduction is excellent.

1) Definition of preservation and food-spoilage micro-organisms
Food preservation is the process of treating and handling food to stop or greatly slow down spoilage (loss of quality, edibility or nutritive value) caused or accelerated by micro-organisms. Some methods, however, use benign bacteria, yeasts or fungi to add specific qualities and to preserve food (e.g., cheese, wine
Electricity generation provides 18,000 terawatt-hours of energy a year, around 40 % of humanity’s total energy use.
It produces more than 1010 tons ofCO2 every year.
There are Wide range of technologies
