Poor interfacial structure and severe agglomerations of carbon fiber (CF) are significant problems that face carbon fiberreinforced aluminium (CF/Al) composites. Thus, CF was surface modified with nano copper particles (Cu) to overcomethese problems. Two groups of CF/Al composites (uncoated and coated) at different weight percentages of reinforcement(0, 5, 10, 15, and 20) were fabricated using the planetary ball milling method and then uniaxially hot coined at 550 ℃ under700 MPa. The results showed that CF refined the crystallite size of the Al matrix, and no Al4C3 or Al2Cu were detected inXRD patterns. The density and thermal expansion of composites reduced with increasing CF percentage in all samples. The electrical and thermal conductivities are improved up to 10 wt% of uncoated reinforcement and 15 wt% of coated one. The mechanical test results revealed that by increasing CF, the compressive strength of composites decreased while thewear properties improved for both groups. Cu deposition on CF improved the bonding between reinforcement and matrix,producing composites with better interfacial bonding, fewer agglomerations and porosity, and higher values of the propertiesof the composites.

Background: Acute lymphoblastic leukemia (ALL) is the most common cancer diagnosed in children and represents approximately 25% of cancer diagnoses among those younger than 15 years of age. Aim and Objectives: This study investigated substitutions in the ATP synthase subunit 6 gene of mitochondrial DNA (mtDNA) as a potential diagnostic biomarker for early detection and diagnosis of acute lymphoblastic leukemia. Based on mtDNA from 23 subjects diagnosed with acute lymphoblastic leukemia, approximately 465 bp of the ATP synthase subunit 6 gene were amplified and sequenced. Results: The sequencing revealed thirty-one mutations at 14 locations in ATP synthase subunit 6 of mtDNA in the ALL subjects. All were identified as single nucleotide polymorphisms (SNPs) with a homoplasmic pattern. The mutations were distributed between males and females. Novel haplotypes were identified in this investigation: haplotype (G) was recorded in 34% in diagnosed subjects; the second haplotype was (C) with frequency of 13% in ALL subjects. Neither of these were observed in control samples. Conclusions: These haplotypes were identified for the first time in acute lymphoblastic leukemia patients. Five mutations able to change amino acid synthesis for the ATP synthase subunit 6 were associated with acute lymphoblastic leukemia. This investigation could be used to provide an overview of incidence frequency of acute lyphoblastic leukemia (ALL) in Saudi patients based on molecular events.
