Blood culture is microbiological culture of blood. It is employed to detect infections that are spreading through the bloodstream. In medicine venipuncture or venepuncture is the process of obtaining a sample of venous blood. Usually a 5 ml to 25 ml sample of blood is adequate depending on what blood tests have been requested. In many circumstances it will be done by a phlebotomist, although nurses, doctors, some EMTs, paramedics, other medical staff and chiropractors are also trained to take blood. Blood is most commonly obtained from the median cubital vein, on the anterior forearm (the side within the fold of the elbow). This vein lies close to the surface of the skin, and there is not a large nerve supply.Minute quantities of blood may be taken by fingersticks sampling and collected from infants by means of a heel stick or from scalp veins with a butterfly needle

Battery Recycling Service is a recycling activity that aims to reduce the number of batteries being disposed as municipal solid waste. It is widely promoted by environmentalists concerned about contamination, particularly of land and water, by the addition of heavy metals and other toxic chemicals from batteries. Most types of batteries can be recycled. However, some batteries are recycled more readily than others, such as lead-acid automotive batteries, button cells, alkaline and rechargeable can.
