With the twenty - First century, It becomes clear to us that for 110 years the Japanese - Chinese relations have been witnessing big radical events and developments. ( we take the year of 1949 as the starting date for this relations). In order to prove hypothesis the study divided in to four chapters. - The first chapter deals with explaining the factors of the subject of the Japanese - Chinese relations which described as Indirect threat and aggressive relations from Japan to China after the Second World War by Japanese entering in the American world strategy, in order to destroy the communist china's system which decleard in 1949, because the united states understood that the new system in Beijing could threat American's Interests in the Asian - Pacific - region. As a result, the united states played a very important role in limiting the chinese danger by, making Japan as a center of it's strategic world. Until 1972 Washington came closer to china than Japan which played very important role in blockade the new Chinese system, as a result Japan tried to encourage its relations with china in order to enter the big China's Markets and arrive to the natural material in the Chinese tretoriarties, therefore Japan could sign the friend ship and security treaty with the communist government in china in 1978. - The second chapter contained explanation the Japanese - Chinese relations after the end of the cold war in 1990 by dealing with the variable changes and real domestic facts of these relations such as economic, strategic and political obstacles, or encouragement. - In addition to that we deal with the regional and International factors, which strengthen or weaken these relation, in the third chapter of this study, and we talked about the important question which influenced of the relations between the Japan and China. - Finally the forth chapter dealt with the future dimensions of these relations which will lead to a great changes in the Japanese - American relations. In addition to that we deal with the future relations between Japan and China, if the international system changes to the multilateral poles system in stead of unilateral pole system therefor, Japan may become a great economic pole in this hypothesis International system, and can control of the south East - Asia, which will lead china to refuse the Japanese control of this region, and will lead the two countries to compete of the predominance of this space. On the other hand, china will become a great pole power in the International multilateral poles system, which reduce one of the opportunities for china to oblige it's policy and strategy of their region and world system, that lead the two countries (Japan - China) to enter strong competition and deferences about many problems, such as the Diyon question, economic relations, Chinese strategic arrangement, and stability in this region, which may center of gravity in the world economy in the future. There are many factors have enhanced the two countries to expand their cooperation on the bases of their common Interests in spite of the viasa - vise strategy between them. But the Chinese continuous effects to modernize its military forces in order to become a major force in Asia has threat the Japanese economic goals and its Interests in this region. On the other hand the Japanese leaders believed that the strategy to deal with china in the future, which becomes the big pole power, should be based on bilateral powers, and standing to avoid any tensions between them, in this important region for both of them, which might threat the Japanese goals, and Chinese Interests and arrangements. This study has concluded that the future relations between the two countries will witness cooperation in the economic, technological, political and security fields, especially with influenced multilateral power in them region, and make and encourage this cooperation and coordination between them in the different fields. But this cooperation will not in any case prohipt the competition between them, and will try to do continuous attempts by each one of them to take advantage of the weak points of each other, in order to certain it's control on the Asia - pacific region, in order to continuos there terietorial intrests and global intrests too.

The effects of nutrients and physical conditions on phytase production were investigated with a recently isolated strain of Aspergillus tubingensis SKA under solid state fermentation on wheat bran. The nutrient factors investigated included carbon source, nitrogen source, phosphate source and concentration, metal ions (salts) and the physical parameters investigated included inoculum size, pH, temperature and fermentation duration. Our investigations revealed that optimal productivity of phytase was achieved using wheat bran supplemented with: 1.5% glucose. 0.5% (NH4)2SO4, 0.1% sodium phytate. Additionally, optimal physical conditions were 1 × 105 spore/g substrate, initial pH of 5.0, temperature of fermentation 30˚C and fermentation dura

Novel derivatives of 1-(´1, ´3, ´4, ´6-tetra benzoyl-β-D-fructofuranosyl)-1H- benzotriazole and 1-(´1, ´3, ´4, ´6-tetra benzoyl-β-D-fructofuranosyl)-1H- benzotriazole carrying Schiff bases moiety were synthesised and fully characterised. The protection of D- fructose using benzoyl chloride was synthesized, followed by nucleophilic addition/elimination between benzotria- zole and chloroacetyl chloride to give 1-(1- chloroacetyl)- 1H-benzotriazole. The next step was condensation reaction of protected fructose and 1-(1-chloroacetyl)-1H- benzotriazole producing a new nucleoside analogue. The novel nucleoside analogues underwent a second conden- sation reaction with different aromatic and aliphatic amines to provide new Schiff b
