In conclusion, this study indicates that: the exposure to high temperature causes changes in the compositions of some constituents of blood.

This research consists of the synthesis of two Schiff base ligands whose name are as follow: phenyl -3- methyl -5- pyrazolone thiosemicarbazone = (L1) and Phenyl -3- methyl -5- pyrazolone-4- phenyl thiosemicarbazon = (L2) The complexation of the above ligands with some transition metal ions (Cr (III), Mo(V), W(VI)) afforded metal complexes which have been characterized on the basis of their (C.H.N) elemental analysis, IR, UV-VIS, and atomic absorption. The molar conductivity measurement and melting point of prepared complexes were measured to investigate the proposed structure as an octahedral.

This study deals with the preparation of Schiff- base ligands from the reaction of salicaldehyde with ethylenediamine in the ratios 1:1 of ligand (1) and 1:2 of ligand (2). Their metal complexes with ions Fe (11), Co (11), Ni (11), and Cu (11) were also prepared. The electronic spectrum of all these complexes and the IR spectrum were studied. The ratios of dissociation of these complexes were investigated via radiation by using mercury lamp in the wavelength of 365 nm. It is noticed that these complexes dissociate slowly during the process of radiation.

Pomeron coupling to photons has been analyzed. As the pomeron assumed to couple to hadrons through their constituent quarks and since the photon has no constituent quarks it's coupling to the pomeron is not well known. We proposed that the pomeron may couple to two photons in away similar to that of pseudo scalar particles (π0, η, ή). To justify our model we have calculated the photon-proton total cross section in the region where a single pomeron is dominated. For completeness the contribution from reggeons exchange at low energies has been included. A comparison with the data shows a good agreement.

Tensile testing of matrix and four different fabric polyamide composites was performed at various loading rates ranging from (8.16* 10-5 to 11.66 * 10-5 m/sec) using a servohydraulic testing apparatus. Four kinds of reinforcements woven glass fiber (WGF), random glass fiber (RGF), kevler fiber (KF) and carbon fiber (CF), and one kind of viscoelastic matrix, polyester (P). The results showed that the linear strain (≤ 0.5) the three parameter model gives a good agreement with experimental results. The elastic modules of the viscoelastic matrix and composites tend to increase with increase of both strain rate and time. The experimental results were comparison with numerical results for simple study case has shown some agreement, which indicate the effectiveness of the ansys program used.

Historical earthquakes catalog, which were felt in the Stable Continental Regions (SCRs) of the Arabian plate for the period (600 to 1900 A.D.), was compiled. The spatial distribution of these earthquakes appears as clusters of events in the northeastern parts, and absence of events in the other parts. This may be attributed to concentration of the population centers in the northern parts relative to other parts and / or to that the seismicity level is very low. These events have a shallow focal depths. This is a characteristic feature of the SCRs. The cumulative strain release curve exhibits two periods of high seismicity separated by low seismicity period. There is a relative quite period extends from (1194 to 1900).This quite period may appear hiatus in seismic activity or in the documentation. The b–value in magnitude relationship was low and this low value is a characteristics feature of the SCRs earthquakes.

This paper contains some results a bout fully bounded modules. Various conditions where given to ensure that bounded modules are fully bounded modules.

Given aset of permutation {p1,p2, … . pk} on aset S, we say that the set of permutation is transitive on S if for every ordered pair of elements a,b € S, there exists at least on Pi for which (a) Pi=b. A permutation set for which there is exactly one Pi which maps a to b is called Sharply transitive.
For example, if on the set consisting of the three elements {1,2,3} we represent the permutation which maps 1 3 ,2 2 and 3 1by (321). Then the following set of permutation is transitive.(123),(132),(213) and (321) and the last three permutation form sharply transitive set. This construction give a set of mutually orthogonal latin squares. A set S of mutually orthogonal latin squares(MOLS) is maximal if no latin square is orthogonal to each member of S.

A quaternary structure of Zn:Cd:S:Cu thin films were prepared by chemical spray pyrolysis method with different concentration of Zn and Cu in the solution. The structure and the component were examined by X-ray diffraction , which obtained that all the prepared thin films are polycrystalline and have many phases. The optical characteristics were measured by using a Uv-Vis. Spectrophotometer from the absorption and reflectance spectra within the range (200-1000 nm), such as the energy gap (Eg) , extinction coefficient (k) and the refractive index (n). We found energy gap changed with concentration and the components of the solution. The value of the energy gap ranged between (1.6-2.5 eV) and the high value of the extinction coefficient given when the quantity of Zn equal to 20ml in the solution and this value equal to 0.55 at wavelength equal 550nm. Also the value of refractive index takes a wide range, it's value decreased when the quantity of Zn was increased. From the D.C. conductivity measurements at the range (295-475K) obtained that the films have two activation energies varied with the variation of the temperature and the concentration of the elements in the compound. From the Hall effect measurements all films which doped by Cu were p-type.

Six types of composite polymeric materials were prepared. Two types of the matrix matter were used (Low density(PE) polyethylene and (PVC) poly chloride vinily ) . Also three types of fibers were used (Short glass fiber, woven roving glass fiber and woven roving nylon-6) .
