Question 89 - A hemocytometer is a device that is used for counting cells. In an engineering experiment, 100 microlitres of cell suspension is diluted with 50 microlitres of Trypan blue dye. Only death cells appear blue in color when stained with the dye. There are 57 cells detected in a hemocytometer, where 5.3 % of them appear blue when the chamber of the meter is placed under a microscope. Each square of a chamber can contain 0.0001 mL of liquid. (a) Calculate the number of viable cells. (b) The cells ocupied 5 squares. Calculate the average number of viable cells / square. (c) Calculate the dilution factor of the cell suspension by using the formula : Dilution = final volume / initial volume. (d) Calculate the concentration of viable cells / mL by using the formula : Concentration = (Average number of viable cells / square) x dilution x (square / volume).
1 4587in the farm,water tank of 8000 litter capacity situated in 12 meter above.Farm owner want to lift 7000 litter of water within 7 minute to water tank of 12 meter above.which motor having HP rating is suitable for pumping??
1 3291we have two generators different capacity on 15 MW and other 6MW at 11 KV , 15 MW gen. bus short level current 40KA,and 6MW short level current 25KA,, length of cable 100MTR between 6 MW from 15MW gen. for bus coupling . kindly tell any one can we use both NGR OR one NGR from any GEN. BOTH NGR has diff. rating. Tariq pakistan
1679We are dealer in Maharashtra State & We have recd. form C from dealer of Maharashtra State against our E-1 form. Now assessing authority is asking for counterfoil of our E-1 form. But, our E-1 form counterfoil is misplaced somewhere & assessing authority is disallowing the C form which is recd. from Maharashtra State.Please let us know the option for allowing C form?
