What type of waste is most commonly produced in hospitals? These are infectious wastes, hazardous wastes, and radioactive wastes. Of these three hospital waste sub-categories, infectious and anatomical wastes — like surgical waste or bloody bandages — make up the majority. Which waste is used in landfilling? Municipal solid waste (MSW) and faecal sludge are […]
What causes crankcase Blowby?
What causes crankcase Blowby? When you combine a large cylinder bore, high cylinder pressure through turbocharging, many hours of use and marginal maintenance, excessive blowby is the result. The leakage of any combustion gases, air, or pressure into the engine’s crankcase is considered blowby. What are crankcase emissions or blowby gases are? The unwanted gases, […]
How do we reduce carbon monoxide?
How do we reduce carbon monoxide? Steps to Reduce Exposure to Carbon Monoxide Keep gas appliances properly adjusted. Consider purchasing a vented space heater when replacing an unvented one. Use proper fuel in kerosene space heaters. Install and use an exhaust fan vented to outdoors over gas stoves. Open flues when fireplaces are in use. […]
What is vertical centrifugal pump?
What is vertical centrifugal pump? Vertical centrifugal pumps for low viscosity fluids Vertical inline centrifugal pumps, as their name implies, are single stage centrifugal pumps that are specifically designed for vertical installation. Vertical centrifugal pumps are common for the transfer of low viscosity fluids over a range of flow rates and heads. What are the […]
Why is recycling batteries good for the environment?
Why is recycling batteries good for the environment? Recycling batteries saves natural resources, because plastic and metals from used batteries can be used to make new batteries and protects the environment by keeping heavy metals out of landfills and the air. How should you dispose of batteries safely? Simply take any batteries which you need […]
Why are metals conductive and polymers not conductive?
Why are metals conductive and polymers not conductive? Why are metals better conductors than polymers? These electrons are known as delocalised and so are ‘free to move’ across the surface of the metal. These free movement of electrons allows electricity to pass across a metal. In polymers, no such situation arrises and so electricity cannot […]
What is km in Lineweaver-Burk plot?
What is km in Lineweaver-Burk plot? The y-intercept of the Lineweaver- Burk plot is the reciprocal of maximum velocity. KM: Michaelis-Menten constant or enzyme affinity. The lower the KM the higher the affinity. Graphically the x-intercept of the line is -1/KM. Kcat: turnover number, or reactions per unit time. What happens when there is a […]
What is a monomer What is a polymer?
What is a monomer What is a polymer? All monomers have the capacity to form chemical bonds to at least two other monomer molecules. monomers. Polymers are a class of synthetic substances composed of multiples of simpler units called monomers. Polymers are chains with an unspecified number of monomeric units. How do monomers form polymers?
