How to charge two bodies(spheres) in contact by electrostatic induction



                Here we charge using a negative body
                                         Steps
1.       Bring the charged body near a sphere. There would be separation of charges on the sphere, positive charges would move near the negatively charged inducing body and the negative charges would move away by repulsion into the next sphere.
2.      Disconnect the two spheres from touching each other.
3.      Then remove the inducing body.

How to make money rearing snails



               Rearing of snails can be a very productive pastime in Nigeria. It needs little input in terms of human effort. The African giant land snail is the common specie of snails in Nigeria, and luckily it is edible. Its scientific name is  Achatina fulica.  Starting up a backyard snail farm relatively easy compared to other animal farms. In Nigeria costs should range from about 500 naira to about 10,000 naira. Of course there is no limit to the amount of capital used for start up. The advantage is this is a business that can be started with a low as 500 to 1000 naira.
               Snails are very prolific animal that lay eggs and they do not need to mature before they start laying eggs. They usually are not affected by diseases but may be attacked by insects that crawl on the ground such as termites, ants etc. Just make sure the snail cage is really partitioned from other areas
               Since you literally do not o anything to set up a snail farm other than to buy some small snails, keep them in a secluded moist area and feed them leaves or starchy foods then it means you have a high turnover i.e. high profit margin after sales.
               Not all snail types grow up to become big. So make sure before you buy baby snails at the market ask the trader for a specie that is suitable for rearing. You will get snails in any of the big markets around.
               When your snails are fully grown you can sell them back to the traders you brought them from as babies or sell them to all the numerous roadside food joints. You can also sell them to bigger retail foods outlets like zartech but you would have to register your farm with the corporate affairs commission to do that. It takes about six months for snails to grow to maturity.

Warning: Snails must not come in contact with salt. Do not give them food waste that contains salt in them.

The French policy of assimilation in African colonies.



                          The French policy of assimilation in African colonies.
When the French colonized certain parts of Africa they met people who already had customs, values and traditions but they nevertheless embarked on a policy to turn the Africans into French people. This was not something new in the annals of history, throughout medieval times nation have sought to conquer nations so as to expand their boundaries, spread their cultures and or civilizations thus effectively turning the conquered nations into their own people.
The French went on to teach the people the French language, the French customs, the French history and a whole lot more. Things at the time that might have elevated the French language, culture and tradition to an elite level and would be aspired for by the ’locals’.
But the whole process never fulfilled it’s aims.
