The first human vaccines against viruses were based using weaker or attenuated viruses to generate immunity. The smallpox vaccine used cowpox, a poxvirus that was similar enough to smallpox to protect against it but usually didn’t cause serious illness. Rabies was the first virus attenuated in a lab to create a vaccine for humans. Egg-Based … Read more

A fuel cell is a device which produces electric energy, through a chemical reaction. Fuel cells use positively charged ion(Hydrogen) and an oxidising agent (oxygen).There are many types of fuel cells, but they all consist of a cathode,an anode, and an electrolyte that allows positively charged( hydrogen) ions to move between the two sides of … Read more

Ultraviolet (UV) disinfection systems contact the treated secondary wastewater with UV light bulbs that are encased in clear housings. The UV light kills pathogenic organisms by using a germicidal photochemical wavelength. Unlike chlorination, UV leaves no residual in the wastewater with which to be concerned. Plants that use UV must either have dual UV systems … Read more
