journal of al-qadisiyah for pure science(quarterly), 2007, Volume 7, Issue 3, Pages 257-272

A single fiber drag-out test was used in this study to measure the critical energy
release rate of a crack at interface of composite ,using Nairn model at the initiation
of crack (knik point) or the beginning of the difference in elastic behavior between
fiber and matrix and the critical energy release rate when the crack length equal
embedded length (peak point ) or full debond , the difference between these points
effected by the strength of adhesion between the fiber and the matrix and also by
the wettability or diffusion of polyester monomer into interfibrillar space where
polyethylene is solid fiber while kevlar is rope fiber .

The photodegradation of n-hexacosane (n- C26H54) by sensitized zinc oxide was investigated. The zinc oxide was modified by different weight of crystal violet (0.1, 0.2, 0-3, 0-4, 0.5, 0.6, 0.7 and 0.8) gm using a Pyrex state reactor 25 cm3 irradiated with modified immersion halogenated lamp ( 400 -700 ) nm. at 298 K with air flow.
The photodegradation of n-hexacosane using sensitized ZnO, which is achieved by the irradiation of suspended solution consists of 0.01 mole n-hexacosane dissolved in 25 cm3 of n-nonane with 0.12 gm of sensitized ZnO by visible light from external source through a side window of quartz inside a Pyrex photo reaction cell of 25 cm3 at 298 K.
Several experiments were carried out at various conditions to attain the best degradation of n-hexacosane using sensitized ZnO. These experiments include the amount of dye on fixed mass of ZnO, the amount of sensitized ZnO, the size of its particles, the flow rate of air flow in the reaction cell, the temperature effects and the time of irradiation. The main photolytic products of n-hexacosane photodegradation processes were heptane, octane, nonane, dodecane and tetradecane.
Gas chromatographic using FID and IR spectrophotometric techniques were used to identify the photocalalytic degradation products. Also the sensitized ZnO and dye were studied by using X-Ray Diffract ion spectrometric technique.
According to the obtained results a reaction mechanism of the photodegradation processes of n-hexacosane by sensitized ZnO was suggested.

Artificial Neural Networks (ANN's) are largely used in applications involving classification or functions approximation. It has been proved that several classes of ANN such as Multilayer Radial-Basis Function Networks (RBFN) are universal function approximators . Therefore, they are widely used for function approximation .
In this paper ,we examine the similarities and differences between RBFNNs compare the performance of learning with each representation applied to the interpolation problem. Nonetheless, this paper should help the reader to understand which basis function and which efficient method should be employed for particular reconstruction problem. It should also encourage the reader to consult the literature pointed out in the bibliography for further studying.

The glutathione peroxidase, vitamin E and dienhydroperoxide in serum were investigated in 30 subject with Type 1 (insulin-dependent) diabetes mellitus and in 30 healthy others. The mean conjugated hydroperoxide(CDH) value in the serum of diabetic patients were significantly higher than those in the control subjects (conjugated dienhydroperoxide p<0.01). The Glutathione peroxidase activity and the levels of Vitamin E significantly decreased(GPx p<0.05 while Vitamin E p<0.01). These data suggest that hyperglycemia induces oxidative stress in sera of patients compared with healthy controls and that antioxidants which used in the study are effective against oxidative injury.

In this paper the point spread function (PSF) for multi-rectangular aperture with no aberration were found numerically with a Q-basic computer program and analytically by deriving suitable equations. And by comparing the two results they were shown a good coincidence which assure the trueness of the computer program.
The values of PSF of the single rectangular aperture was compared with that of single square aperture previously found , and it is found that the PSF for a rectangular aperture has become wider by square root of aspect ratio value in one direction and narrower by the inverse of the square root of the aspect ratio value in the other direction.
The PSF of multi-rectangular aperture were also computed when the focus error were found with a values of 0.25 and 0.5, and it found that the value 0f PSF of the peak have been decreasd by 73.6% of its original value with no aberration for the value of the focus errorw20=0.25 and by 28% of its original value for w20=0.5.
