Title: Simplify and Improve readability on some conditions

I changed some conditions to improve readability.

Example:
```ruby
def xpto(param)
if param
do_something
do_something_again
do_something_again_and_again
end
end
````
To
```ruby
def xpto(param)
unless param
do_something
do_something_again
do_something_again_and_again
end
```
