چکیده
FIG. 2. Circuit. The plate supplies of the two tubes are not shown. These come from a single power pack utilizing an Inca C-65 transformer, a 5Y3 tube, two 12 henry chokes, two 4 microfarad condensers, and a 50,000 ohm resistor from which the 250-volt line is taken. The transformer heats the rectifier filament and supplies the heaters of 885 and 6L6 using a separate secondary and resistances of 3.4 and 1.38 ohms, respectively. R1 50,000

An alternative in vitro approach to drug screening has been the use of human cell cultures for antiviral agents and microbial cell cultures for the assessment of the carcinogenic potential of selected compounds. A number of protozoan species have been also used as drug screens for anti-protozoal agents. The ciliated protozoan Tetrahymena pyriformis species has been widely utilised as a dru...
متن کاملA Simple Apparatus for the Automatic Inoculation of Culture Media †
In connection with certain investigations being carried out in this laboratory, it was found necessary to work with sixto twelve-hour cultures of bacteria in fluid culture media. The apparatus described below was devised to obviate the need of either coming to the laboratory late in the evening to inoculate cultures for the following day's work or of wasting time waiting for cultures to grow ou...

HNAN . h at a growth rate of 0.65 day. On a yeast extract medium with a C/N/P ratio of 100:15:1.2 (Redfield ratio), a mixed ...
متن کاملSeparation of Salmonella Typhimurium Bacteria from Water Using MWCNTs Arrays
In this study, Salmonella Typhimurium bacteria removal from polluted water has been investigated using multiwall carbon nanotubes arrays. Experimental results reveal that the contact time, the bacterial concentration and the weight of multiwall carbon nanotubes arrays have positive significant effects on the bacteria removal efficiency. Increasing the contact time and the weight of multiwall ca...
