The concept of permanence conharmonic type Nearly Kahler manifold conditions are obtained when the Nearly Kahler manifold is a manifold conharmonic constant type. Proved that the local conharmonic constancy of type Nearly Kahler manifold is equivalent to its global conharmonic constancy of type. And also proved that the Nearly Kahler manifold conharmonic constant type is a manifold of constant scalar curvature.The notion of constancy of type Nearly Kahler manifolds was introduced A.Greem ([1], [2], [3]) and has proved very useful in the study of the geometry of nearly kahler manifolds. Next nearly kahler manifolds of constant type considered various mathematicians (see. [1], [3], [4], [5], [6], [7]). Comprehensive description of Nearly Kahler manifolds of constant type was obtained V.F.Kirichenko [6]. In [6] it is shown that Nearly Kahler manifold of pointwise constant type description by the identity , where B - a function on Nearly Kahler manifold, . Wherein local constancy of type Nearly Kahler manifold is equivalent to the local constancy of its type. Moreover, the covariant constancy of structure tensors of the first and second kind it follows immediately that, the constancy of type at only one point Nearly Kahler space implies global consistency of its type.

Six-dimensional Kählerian and nearly-Kählerian submanifolds of Cayley algebra are considered. Spectra of some classical tensors of such submanifolds of the octave algebra are computed. It is proved that a nearly-Kählerian six-dimensional submanifold of Cayley algebra is conharmonically flat if and only if it is holomorphically isometric to the complex Euclidean space with a canonical Kählerian structure.

The research included the separation of thioredoxin (Trx) from human blood serum using different biochemical techniques. One proteinous peak had been isolated by gel filtration using sephadex )G-50) that produced by ammonium sulphate precipitation(65%) after dialysis. It was noted that there are two peaks of Trx when using ion exchange-type DEAE-cellulose for the product of gel filtration column. The approximately molecular weight of the isolated Trx using gel filtration chromatography (G-50) and electrophoresis technique type SDS-PAGE were (12305 + 190) Dalton and 12461 Dalton respectively . The results showed that inhibited and activated effects of drugs on Trx working. The results showed that inhibited to 44.59% for paracetamol, dexathamazone, diphenhydramine-HCl, theophlline anhydrous, pseudoephedrine, ceramide and caffeine anhydrous, but metronidazole and chlorpheniramine malate have activated effect to 110.8% and 21.62 respectively.

In this paper, the preparation of five samples of amalgam alloy used for the restoration of teeth has been done using the amalgamation device for mixing alloys with mercury. The alloys included four high copper amalgams which are (SDI, Septalloy NG 50, YDA alloy, TG alloy) and the percentage of copper (28, 22.7 , 25, 24) % respectively, which are ready fillings. While the fifth alloy (Septalloy NG70) is for low copper amalgam with Copper ratio of 12.7%. The X-ray diffraction has been tested to study the structural properties of these samples and found for the four high-copper alloys increment in the intensity for the diffraction values of the two phases Ɛ - Cu3Sn, ƞ - Cu6Sn5 with the disappearance of the phase γ2 - Sn7Hg which decreases the intensity of this phase with copper increment, while in the low- copper alloy it shows an increase in the peaks representing the phases Ɛ - Cu3Sn, ƞ - Cu6Sn5 with an increasing proportion of copper in the amalgam, as the relationship is positive between copper increment and the tops increment of these two phases, and the relationship is inverse between the copper ratio increment in amalgams and phase γ2 where phase reacts with Eutects silver - copper component phases γ1 - Ag2Hg3, ƞ - Cu6Sn5. Also the mechanical and thermal properties has been studied for each one of five groups of amalgam alloy like compressive strength , micro hardness , thermal conductivity

The effect of different concentration of crude oil had been examined upon Oscillatoria splendida, it was depended upon measuring Growth as optical density, Chlorophyll, Phycocyanin and Protein concentration as an Physiological activities indicator of crude oil effects on Oscillatoria splendida, in addition to morphological changes. The growth optical density in the control sample in the day 30 was (0. 34), while it was (0.148) & (0.08) at 0.25% & 0.5% of crude oil respectively, 41% of chlorophyll concentration has been reduced under effect of 0.25% of crude oil, and reduction 63% of chlorophyll concentration with treatment 0.5%. Protein was reduced 45% at 0.25%, and 82% at 0.5% of crude oil. It was observed reduction growth, chlorophyll, phycocyanin as well as the protein concentration to a minimum under the influence of crude oil treatment 1% and 2% respectively. As well as the absorption spectrum infrared by FTIR show there were absence of methyl group CH3 at (2950 cm-1), (2870 cm-1) and other bundle such as (2300) cm-1, (1500) cm-1, and this is could due to consumed by this species.

A method presented to calculate the effect of radiation pressure on orbital elements for different altitude of satellites, the necessary calculation down by using modern Mat lab computer language. Typical results presented for radiation effect at deferent values of area mass ratio(A/m), the computed results indicated that the orbital elements much affected by solar radiation at high value of area mass ratio, also the effect on high orbit satellite is much more than that on low orbit satellite. The study also include the solar radiation pressure at two different value of ascending node ( Ω = 00 and Ω = 1800 ).

The strength tests also showed the results of (AIV) shows it's don’t exceed than 9.95%) for all sample in the study area , and for compressive strength that taken from point load test shows that all stations classified the aggregate strength (very strong - extremely strong) according to[3] . Durability geotechnical tests (Loss Angeles) results shows the percentage of weight loss for the four samples are not exceed the defined value 35% , so it is suitable for use for concrete and sub-base coarse aggregate and soundness test results shows suitability of all samples to use in concrete works . The chemical analysis shows suitability according to the standards .
