The present investigation focuses on developing cost-effective Carbon/Glass/Kevlar fiber-reinforced polymer hybrid composite laminates for achieving its synergistic effect on flexural and impact performance. It investigates the effect of stacking sequence induced by the use of different fiber types (Kevlar = K, glass = G, and carbon = C) on the flexural and impact performance of the composites. Five hybrid composites (labelled as A = [G2K3G2], B = [KG2CG2K], C = [CKGCGKC], D = [CGKCKGC], E = [CK2CK2C]) and three plain (i.e., non-hybrid) composites (F = [K]7, G = [G]7, H = [C]7) have been fabricated through manual pre-preg lay-up manufacturing techniques. The flexural strength and modulus, hardness, and Izod impact strength have been evaluated for the fabricated composites and compared. The results showed that the D-type hybrid composite achieves the maximum positive hybrid effect as compared to other hybrid composites, possesses a hardness of 59 BHN, a flexural strength of 380 MPa, and modulus of 36 GPa, and impact strength of 80 KJ/m2. The fracture surfaces of the hybrid composite specimen have been analysed using scanning electron microscopy, and compared against the properties achieved for enabling correlations. Furthermore, the cost-efficiency of the hybridization in terms of flexural strength/cost, modulus/cost, and impact strength/cost ratio were evaluated for potential engineering and design applications.

Summary Chromosomal abnormalities in 55 AML patients from Orissa (India) were studied. Of them, 12 patients had only abnormal metaphases (AA), 41 patients had both normal and abnormal metaphases (AN) and the rest 2 patients exhibited only normal metaphases (NN). Basing on the number of chromosome all the patients were classified into 5 sub-groups like (1) normal diploidy with 46 chromosomes in 2 patients, (2) pseudodiploidy group with 46 chromosomes and some structural abnormalities in 4 patients, (3) hypodiploid group with Ͻ46 chromosomes in 37 patients, (4) hyperdiploidy-A group with 47 to 50 chromosomes in 8 patients and hyperdiploidy-B group with Ͼ50 chromosomes in 4 patients. Primary translocations like t(8, 21), t(1, 14), t(9, 22) were detected in 8, 1 and 7 patients respectively. In addition, secondary aberrations were also observed in 36 patients. These secondary aberrations were mostly unstable and nonclonal ones which were present singly or in various combinations. Maximum number of patients achieved complete remmission (CR) from AN subgroup (46.3%) hyperdiploidy-B group (100%), patients with t(8; 21) translocation (75%), patients with trisomy 22 and patients with no secondary aberrations. This study suggests that hyperdiploidy, t(8, 21), trisomy 8, presence of both normal and abnormal metaphases and absence of secondary aberrations are the favourable prognosticators while presence of only abnormal metaphases, presence of more than one secondary aberration, t(9, 22) translocation, hypodiploidy and monosomy 7 are unfavourable prognosticators.
