This study showed that the surface of polymer gives a clear change in the coulor , rapture and scare of the surface resulting from the interaction with high-energy U.V light ) ) in amanner commensurate with the above concentrations of accelerator and with irradiation hours of 250 hours in several stages.
The study of I.R and U.V came in accordance with that showed by the surface of the polymer as it responds to the photo effect of high energy which indicated that the low concentrations (0.025 ,0.05) had accelerated the degradation while the high concentrations ( 0.1, 0.2, 0.4 ) gave astabilization to the polymers.
Via the calculations of the rate of carbonyl formation (ICO) and that of the hydroxyl formation ( IOH ) , their growth was proportional to irradiation time, which is clear indicator of both degradation and stabilization resulted from the addtion of anhydrous ferric chloride and according to the added concentrations to follow the effect of high energy radiation on polystyrene and how the degradation and stabilization take place.

In this paper the effect engenders by fast neutrons and gamma rays on the electrical properties of some silicon diodes was in vestigated. The neutron generator (T-400) was used to induce fast neutrons with energy (En=14 MeV) and the standard source (60Co) was used to induce gamma ray with energy range (1.33-1.17 MeV). The measurements of the samples included studying the characteristics Current–Voltage (I-V characteristics) before and after irradiation taking into account that these samples were exposed to different successive periods of irradiation from the neutron source and to different doses of gamma rays. The results indicate that there are some changes in the properties of the samples that were exposed to fast neutrons, that is, the current increases at low-levels fluency. And with the increase in the neutron fluency the current decreases, this decrease continues with the increase in the neutron fluency till it goes back to a level near to its original one. The results of the samples, which were exposed to gamma rays, indicate a slight change in their properties. The current decreases with increase in the doses and the continuity of providing gamma doses leads to a nil current.

A comprehensive analysis has been made to find out the exact composition of phosphogypsum. Results indicate a high percentage of gypsum (94.75, 1.51) which can be utilized for different purposes after removal of fluoride and phosphorus. Phosphogypsum, a by-product of the phosphate industry, therefore can be used as a raw material for the production of ammonium sulphate, sulphuric acid, plaster and expansive cement. Its evidence of low levels of heavy and poisonous metals allows its use for these purposes. It can also be used in the manufacture of building materials on account of its reasonably high content of silica. The trace levels of alkali metals allow its use in the reclamation of saline soils.

Three quantitative seismicity maps, the a-value map, the b-value map and the estimated maximum magnitude map, have been prepared for the Arabian Peninsula and surroundings. For preparation of these maps, the frequency- magnitude relation has been used where the constants a and b were estimated using maximum likelihood method. These maps are superimposed on the modified seismotectonic map of Arabian peninsula. These quantitative seismicity maps reveal that the Arabian peninsula consists of four high seismic activity zones: Zagros high, Dead sea rift system high, southern Red sea high and Gulf of Aden and Arab sea high. The b-values determined by this study are compared with those determined by other workers for various regions in the Arabian peninsula. They show a good agreement .The maximum magnitude map reveals a Mmax highs comparable with the a and b highs.

In this work, we present some deeper insights in the state-of-the-art in block cipher design. This is mainly achieved by assessment of the evaluation process of the AES (Advanced Encryption Standard). We conclude (with may be a little bit surprising result) that the required security level, for a block cipher to be used for the present and foreseeable future, may be underestimated during AES evaluation. In accordance, we propose a new block cipher that we call Nahrainfish, which we believe that it offers the required security level without a big sacrifice in efficiency and other related criteria. Instead of building Nahrainfish totally from scratch, we have made a benefit mainly from some AES finalists to develop the new cipher by an over-engineering approach leading to the required higher security level. Nahrainfish is a classical Feistel network based on a novel combination of both key-dependent S-boxes and data-dependent rotations. It operates on 128-bit blocks and accepts a variable key length up to 1024 bits. The paper also includes some important notes on the security and performance of the cipher.

It has been shown that data mining uncovers patterns in data using predictive techniques. These patterns play a critical role in decision making because they reveal areas for process improvement. Statistical techniques such as Chi-square test for association are widely used in the medical field. Yet, the interpretation of some of the results approached by the use of this statistical techniques is seems to be a very difficult task. The type of association is often non-linear and hence will mask the important part of the use of this technique.
In this research work a new approach is adopted by scanning the raw data for any possible association (linear or non-linear). More data mining methods and statistical inference were the base tools of this research work.
