Abstract

Astudy for prearated Oxidized Derives of bile acid And Salts for Medical purposes Two methods were used to oxidize some derivation of cholic acid and deoxy cholic acid nsing potassinm in dichromate in acetic acid and chromic trioxide The following compounds were purified: 1. Mchyl(^7-,12-)trihydroxy cholan-24-oate (1). 2. Methyl(3-,12-)dihydroxy cholan-24-oate (11). 3. Methyl(3-,7-)diacetate.l2-hydroxycholan-24-oate (111). 4. Methyl 3-acetate,12-hydroxycholan-24-oate (IV). 5. 3H^roxy,(7-,13)diketocholan-24-oic acid (V). 6. 3-Hydroxy,12-keto cholan-24-oic acid (VI). 7. Methyl 3- h}'droxy(7-, 12-)diketocholan-24-oatc (VII). 8. Methyl 3-hydroxy,12-ketocholan-24-oate (VIII). 9. (3^,13)^iketocholan-24-oic acid (1^). The purified prepared compounds were identified through different methods of identification i.e, I.R, UV-vi^ble-spectroscopy in addition to (coloured tests) Calculation of the sum of OH groups. TLC techniques were also used to test the purity and the speed ofthe rate of flow (RF).

Abstract

first sign ؛ه' heart development in mosquito fish starts in an embryo of 0.6 mm. long. It appears as ١٦٧٢١ thiekenings in the splanchnic mesodermal p^es loeated on bouth sides of the ventral median line ofthe embryo under the foregut. l-'rom these two thitckenings a group of loose cells are detached. These cells represent the heart primordium which develops into the endocardial tube. The endocardial tube appears to be surrounded by the two thickened plates of splanchnic mesoderm. These go to form a heart tube with a double-layered wall. The heart chambers will differentiate in a antero-posterior direction; starting with the bulbus arteriosus then the ventricle followed by the atrium and lastly the sinus venosus. The embryo of7 mm. long shows that the heart chambers are arranged on a bent line. This bent continues and the heart chambers will occupy the perieardial cavity. In the new born larva the bulbus arteriosus assumes an anterior position, the ventricle has the dorsal, the atrium has the ventral, and the sinus venosus has the posterior position. With the development, the ventricle and the atrium interchange in their positions. This interchange occures as a result of a rotary motion of 180؛ in a clockwise direction. As a result the ventricle occupies a ventral position and the atrium occupies . a dorsal position. Thus the heart takes its final shape as that in the adult fish.

And the butt joint welding is better than the lap joint welding during the fatigue loaded.The experimental results of the effect of W'elding current showed that more increasing and more decreasing the value of the heat input, during the welding was found to produce mechanical brittleness on the buttjoint welding during the static and dynamic loading. Also it was found that welded lap joint properties are improved when the welding current is increase during the static and dynamic loading.

Abstract

We found that 4,5- diphenyl- 3(2- propynyl) thio- 1مر-triazole [1ا forms a complex with Pd (11) ion of ratio 1:1 which absorbs light in CH2CI2 at 400 nm, and 4,5- diphenyl- 3(2- propenyl) thio- 1,2,4- triazole [II] forms complexes with Pd (II) ion of ratio 1:1 which absorbs light at 390 nm, and of ratio 2:1 which absorbs light at 435 nm. On the other hand, we found that the new derivative 4- phenyl- 5( p- amino phenyl) -3- mercapto- 1,2,4- triazole ل111ا forms complexes with Cu (II) ion of the ratio 1:1 which absorbs light at 380 nm, with Ni (II) ion of the ratio 3:1 which absorbs light at 358 nm; and with Co (11) ion of the ratio 3.2:1 which absorbs light at 588 nm. The ratio of the complexes were determined by measuring the electronic spectra of the complexes in CH2G2 and (CH^NCHO at different concentrations ofthe ligands and f،xed ' •' of the metal ion in every case, then applying the molar ratio plots on the data.

Abstract

In the present work theoretical relations are derived for the efficiency evaluation for the generation of the third and the fourth harmonics u$ing crystal cascading configuration. These relations can be applied to a wide class of nonlinear optical materials. Calculations are made for beta barium borate (BBO) crystal with ruby laser /.=694.3 nm . The case study involves producing the third harmonics at X. =231.4 nm of the fundamental beam. The formula of efficiency involves many parameters, which can be changed to enhance the efficiency. The results showed that the behavior of the efficiency is not linear with the crystal length. It is found that the efficiency increases when the input power increases. 'I'he walk-off length is calculated for different spot sizes. It is found that when the spot size increases , the walk-off length increases too.

'I he s and w lineshape parameters were measured using high-resolution gamma spectrometer with high pure germanium detector of 2.1 keV resolution at 1.33 MeV of 60Co. The change of defects concentration (Co) with the deformation level (e) is found to obey an empirical formula of the form Cd - A £ B where A and ٥ are positive constants that depend mainly on the deformation procedure and the temperature at which the deformation takes place.
