Solutions

Expert Solution

The FAB (French-American-British) classification of leukemia, Acute Myelomonocytic Leukemia is:

a. M1- Acute myeloblastic leukemia with minimal maturation,

b. M2- Acute myeloblastic leukemia with maturation,

c. M3- Acute promyelocytic lukemia,

d. M4- Acute myelomonocytic leukemia with eosinophilia,

e. M5- Acute monocytic leukemia.

Q. Blasts comprise 50% of the nucleated cells in the peripheral blood

30% of blasts are Peroxidase weakly positive

Most Blasts are non-specific esterase positive

All Blasts are specific esterase negative

a. M2- 30% of blasts are Peroxidase weakly positive

b. M3: Acute promyelocytic leukemia (APL)- Most Blasts are non-specific esterase positive,

c. M5: Acute monocytic leukemia- Blasts comprise 50% of the nucleated cells in the peripheral blood,

d. M6: Acute erythroid leukemia- 50% erythroid precursors of nucleated cells in BM, 20% myeloblasts of non-erythroid cells in BM,

e. M7: Acute megakaryoblastic leukemia- 50% of the blasts are megakaryocytic lineage.

Three blocks of unknown mass m1 = 1.0 kg, m2 = 2.0 kg, and m3 = 3.0 kg are on a frictionless horizontal surface as shown on the figure below. The blocks are connected by ideal, massless strings. A force FL = 12 N is applied to the left block and is directed to the left. A force FR = 33 N is applied to the right block, and is directed to the right. Find the tensions T12 and T23,...

Three machines M1, M2 and M3 produce nominally identical items. The evidence of the engineers past experience is that 5 % of the output from machine M1 is faulty, 3.5 % of the output from machine M2 is faulty and 2.5 % of the output from machine M3 is faulty. On a given day, M1 has produced 15 % of the total output, M2 has produced 30 % and M3 the remainder. An item selected at random is found to...
