CELEBRITY OF THE MONTH
Luigi Aloisio Galvani
279th Birthday, (September 9, 1737 – December 4, 1798)
Discoverer of animal electricity

Luigi Galvani was born in Bologna, Italy, on September 9, 1737. He was an Italian physician who discovered the animal electricity and he is recognized as the pioneer of the bioelectromagnetics. He demonstrated the electrical basis of nerve impulses when he made frog muscles twitch by joining them with a spark from an electrostatic machine. Further experimenting with natural (i.e. lightning) and artificial (i.e. friction) electricity, he concluded that animal tissue contained its own innate vital force, which he termed "animal electricity." Galvani proved that the electricity did not emerge from the animal tissue itself, but from the effect produced by the contact of two different metals in a moist environment (a human tongue, for instance). Galvani devoted most of his early scientific efforts to anatomical topics.

CASE STUDY

Non-Revenue Water (NRW) is a challenge for Global Water Supply System Management: A case study of Dhaka Water Supply System Management

Farok GMG

Non-revenue Water (NRW) is an important component of commercial water system management.NRW is the result of pipelines leakage, improper, illegal service connections and theft water. NRW contributes system loss that is a buzzword. Actually, NRW is uncounted water that has been produced but it is confirmed to be “lost” before it consumes the customer.

ANALYSIS

Effects of sodium azide on callus in sugarcane

Kuasha Mahmud, Nasiruddin KM, Hassan L

The experiment was conducted at the Biotechnology Laboratory, Bangladesh Sugarcrop Research Institute (BSRI), Ishurdi, Pabna, Bangladesh. The effects of different concentrations of chemical mutagen sodium azide (0, 1, 2, 3, 4 and 5 mg/l for 5 days treatment) on callus of sugarcane varieties Isd 37, Isd 39 and Isd 40 were investigated under in vitro aseptic condition.

Performance evaluation of a produced water treatment plant in a crude oil production facility

Howard IC

The present study which was carried out (on a facility that is located on Latitude 04o 35.52’N and Longitude 08o25.45’E) using standard method of analysis monthly for two years has demonstrated that the treated produced water discharged from the crude oil processing into the near shore environment is 63.6% (each for both years) efficient when compared with the Guideline limits of the Regulatory body (Department of Petroleum Resources [DPR] of Nigeria).
