Z.; Turkebaev, T. E.; Bölüm YokDiffusion of helium and formation of helium bubbles in stainless steel in condition of atomic displacement are studied theoretically using standard rate equations [1], Besides this bubble coalescence is assumed to result when collisions occur between bubbles as they migrate by surface diffusion through the solid [2], The dissociative mechanism via self-interstitial He replacement is assumed to control helium diffusion and bubble formation. The theoretically analysis is based on the diatomic nucleation model where two helium atoms are assumed to compose a stable nucleus. For nucleation of interstitial loops, two atoms are assumed to compose a stable nucleaus. In the present work is assumed that coalescence follows bubble collisions resulting from random migration of bubbles in Chandrasekhar’s approximation.Item Proton activation analysis of some chemical elements on a nuclear reactor(Institute of Nuclear Physics of Uzbekistan Academy of Science, Turkish Atomic Energy Authority, 2006) Mukhammedov, S.; Khaydarov, A.; Bölüm YokItem About posssibilities of obtaining focused beams of thermae neutrons of radionucuide source(Institute of Nuclear Physics of Uzbekistan Academy of Science, Turkish Atomic Energy Authority, 2006) Aripov, G.

Trading policies of food and agricultural products are governed by international agreement as well as national regulations.Trade in food and agricultural commodities may be affected by both principal Agreements within the overall World Trade Organization (WTO) Agreement, though neither specifically refers to irradiation or irradiated foods. The principal Agreements of WTO are the Technical Barriers to Trade (TBT) Agreement and the Sanitary and Phytosanitary (SPS) Agreement. The SPS of the WTO requires governments to harmonize their sanitary and phytosanitary measures on as wide a basis as possible. Related standards, guidelines and recommendations of international standard setting bodies such as the Codex Alimentarius Commission (food safety); the International Plant Protection Convention (IPPC) (plant health and quarantine); and International Office of Epizootics (animal health and zoonoses) should be used in such a harmonization.International Standarts for Phytosanitary Measures (ISPM) no. 18 was published under the IPPC by FAO (April 2003, Rome-Italy). ISPM standard provides technical guidance on the specific prodecure for the application of ionizing radiation as a phytosanitary treatment for regulated pests or articles.Moreover, Codex Alimentarius Commission ,Codex General Standard for Irradiated Foods (Stand 106-1983) and Reccomended International Code of Practice were first published in 1983 and revised in March 2003. Scope of this standard applies to foods processed by ionizing radiation that is used in conjunction with applicable hygienic codes, food standards and transportation codes. It does not apply to foods exposed to doses imparted by measuring instruments used for inspection purposes.On the other hand national regulations should take account of internationally agreed Codes and Guidelines regarding the irradiation facilities and radiation processing.Item Nuclear techniques used in soil fertility and plant nutrition(Institute of Nuclear Physics of Uzbekistan Academy of Science, Turkish Atomic Energy Authority, 2006) Halitligil, Mahmut Basri; TAEK-ANTHAMNuclear techniques, which include the usage of radioactive and stable isotopes, had been used in soil fertility, plant nutrition, plant breeding, plant protection and food preservation research works after 1950s. Ultimately these nuclear techniques contributed greatly in increased plant production [1], In general, it is possible to separate the nuclear techniques used in soil fertility and plant nutrition into to groups [2], The first group is the use of radioactive and stable isotopes as a tracer in order to find out the optimum fertilization rate of plants precisely. The second group is the use of neutron probe in determining the soil moisture at different periods of the growing season and at various soil depths precisely without any difficulty. In research works where conventional techniques are used, it is not possible to identify how much of the nutrient taken up by the plant came from applied fertilizer or soil. However, when tracer techniques are used in research works it is possible to identify precisely which amount of the nutrient taken from fertilizer or from soil. Therefore, the nuclear techniques are very important in finding out which variety of fertilizer and how much of it must be used [3], The determination of the soil moisture is very important in finding the water needs of the plants for a good growth. Soil moisture contents changes often during the growth period, so it must be determined very frequently in order to determine the amount of irrigation that has to be done. Conventional soil moisture determination (gravimetric method) is very laborious especially when it has to be done frequently. However, by using neutron probe soil moisture determinations can be done very easily any time during the plant growth period.Item Nitrogen utilization of vegetables grown under plastic greenhouse in Ankara conditions using 15N technique(Institute of Nuclear Physics of Uzbekistan Academy of Science, Turkish Atomic Energy Authority, 2006) Halitligil, Mahmut Basri; Kışlal, Hakan; Şirin, Hamza; Şirin, Cismi; Kiliçaslan A.; TAEK-ANTHAMIn order to find suitable varieties of tomato, pepper and cucumber for plastic greenhouse conditions in Ankara and eventually to identify the best N fertilizer rate greenhouse experiments were conducted for two years. Yazgı Fi variety for tomato, Hızır Fi variety for cucumber and Serademre 8 variety for pepper were chosen to be the suitable varieties to grow in the plastic greenhouse conditions in Ankara. Five N treatments [N0 = 0, N1 = 150, N2 = 300, and N3 = 450 kg N/ha; also, soil N application treatment (Nsoil) equivalent to the fertigation treatment of 300 kg N/ha was included for tomato and pepper, however N rates for cucumber was 131, 266 and 339 kg N/ha; Nsoil being 266 kg N/ha.] were investigated using 15N labeled urea ferilizer. Significantly higher marketable fresh fruit and total dry matter yields and N uptakes values were obtained from N3 treatments for tomato and cucumber, but from N2 treatment for pepper. Also, significantly higher yields, N uptakes and % NUE values were obtained when the same amount of N fertilizer is applied through fertigation compared to the treatment where N fertilizer applied to the soil then drip irrigated.Item Water utilization of vegetables grown under plastic greenhouse conditions in Ankara using neutron probe technique(Institute of Nuclear Physics of Uzbekistan Academy of Science, Turkish Atomic Energy Authority, 2006) Halitligil, Mahmut Basri; Kışlal, Hakan; Şirin, Hamza; Şirin, Cismi; Kılıçaslan, A.; TAEK-ANTHAMIn order to find suitable varieties of tomato, pepper and cucumber for plastic greenhouse conditions in Ankara and ensure both higher yields and lower NO3 leaching greenhouse experiments were conducted for three years. In the first year (2001) of the experiment four different varieties from each vegetable, namely, Tomato (Ecem F1, 9920 F1, 2116 F1 and Yazgı F1), Cucumber (Hızır F1; Rapido, Hana, and Luna) and Pepper (1245 F1, 730 F1, Serademre 8 and 710 F1) had been grown in the plastic greenhouse using drip irrigation-fertigation system. Yazgı F1 variety for tomato, Hızır F1 variety for cucumber and Serademre 8 variety for pepper were chosen to be the suitable varieties to grow in the plastic greenhouse conditions in Ankara. One access tube in each N3 and N0 treatment plots of tomato, cucumber and pepper in 2002 and 2003 experiments were installed for the soil moisture determinations at 30, 60 and 90 cm depths. Readings with the neutron probe were taken before planting and after harvest for the water consumption calculations using the water balance approach and the WUE was calculated on the basis of the ratio of dry matter weight to the amount of water consumed. Tensiometer and suction cups were installed at 15, 30, 45 and 60 cm depths only to N1, N2 and N3 treatments plots of each vegetable in 2002 and 2003. Tensiometer readings were taken just before irrigation. Also, soil solution samples from suction cups were taken at final harvest and NO3 determinations were done with RQFLEX nitrate test strips. Significantly higher yields and WUE values were obtained when the same amount of N fertilizer is applied through fertigation compared to the treatment where N fertilizer applied to the soil then drip irrigated. The nitrate concentrations of the soil solution increased as the N rates increased and no NO3 had been found in the soil solution taken from 75 cm soil depth, indicating that no leaching of N fertilizer occurred beyond 75 cm soil depth.Item Combination of the prompt neutron capture method with other neutron methods for substance elemental content analysis(Institute of Nuclear Physics of Uzbekistan Academy of Science, Turkish Atomic Energy Authority, 2006) Kurbanov, B.
