Fibers Direction Effect on Tensile Elasticity of Epoxy Composites Using Computer modeling

In this research a sample of glass fiber reinforced Epoxy Composite was subjected to a tensile load to study the effect of fiber directions on the tensile elasticity theoretically using Finite Element Method (FEM) . MSC-NASTRAN computer package was used for the purpose of this study. Tensile test was done on the design samples when fibers angled with the Load direction at 0o ,45o and 90o in order to find out the direction which provides the best mechanical properties. Through the tests result and color spectrum analysis, we found that 0o angle provides the best properties, followed by 45o angle, while at 90o angle shows lowest value of elasticity modulus

Isolation of Ps. aeruginosa and study of resistance to some antibiotics and ability to pyocins production.

The study involved the isolation and identification of Pseudomonas aeruginosa , thirty four (34)isolates obtained from (77)samples that were collected from patients attending Kirkuk General Hospital and (2) isolates obtained from (33) samples that were collected from hospital environment and (24) isolates were collected from Kirkuk City environment. The results demonstrated that the pathogenic isolates were resistant to Cefazolin and Carbenicillin by(97.22)%, where as isolates from Kirkuk City environment were resistant to Cefazolin , Carbenicillin and Cefatoxim by (100% , 95.5% , 91.6%) respectively. The results revealed that in Psudomonas aeruginosa the dominant pattern of multiple antibiotic resistance were (PY,CZ,CTX,CN,TOB) The results obtained showed that one isolates has inhibitory activity against Staphylococcus aureus . This isolates could possibly be as one of the pyocin producing isolates without using any stimulators
