For example, if your driveway measures 720 square feet, a 4 inch thick pour will require 9 cubic yards of concrete.Increasing the thickness to 5 inches requires 11 cubic yards of concrete. The extra two yards of concrete will only cost about $130.00.

Clostridium perfringens (C. perfringens) is a spore-forming gram-positive bacterium that is found in many environmental sources as well as in the intestines of humans and animals. C. perfringens is commonly found on raw meat and poultry.
A study by Mendez et al suggests that sugar may inhibit the production of alpha and theta toxins that trigger the gas. Clostridium perfringens, previously known as Clostridium welchii, is the most common cause of clostridial gas gangrene (80-90% of cases). Other clostridia species responsible for the condition include Clostridium novyi (40%), Clostridium septicum (20%), Clostridium histolyticum (10%), Clostridium bifermentans (10%), and Clostridium fallax (5%).
