در این پروژه جذب مولکول های o2، no و co بر روی نانوخوشه های دو فلزی cu5sc و cu6sc+ با استفاده از تابع هیبریدی b3pw91 و سری پایه lanl2dz برای اتمهای cu و sc و 6-311++g** برای اتم های c ، o و n به طور نظری مورد مطالعه و بررسی قرار گرفت. نتایج حاصل نشان داد که اکثر جذب های رخ داده به صورت جذب شیمیایی بوده و همچنین به جز در چند مورد محدود تفکیک پیوند و جذب به صورت اتمی مشاهده نشد. نتایج حاصل از برر...

The method of Cooke (1996) and Punt Butterworth (1999) for computing abundance estimates bowhead whales the BeringChukchi-Beaufort Seas stock is reviewed. These are computed from N4 number that passed within 4km visual range observation ‘perch’ which counted, estimated proportions P4 this standard errors (SE) P4. Errors discovered while assembling data used in developing previous were corrected...

To study the association of autoimmunity and human B cell neoplasia, we have established a model of a B cell lymphoma which expresses a pathogenic autoantibody of defined specificity. The Ig VH gene expressed in this neoplasm was analyzed longitudinally using clinical specimens taken from the splenic lymphoma (S) at diagnosis and from lymph node relapses 3 and 4 yr later (N3 and N4). Southern a...

The nonlinear coefficients, n4, of the time-dependent refractive index for argon are calculated in the non-resonant optical regime. Second-order polynomial fitting of DC-Kerr, γ((2))(-ω; ω, 0, 0), electric field induced second harmonic generation (ESHG), γ((2))(-2ω; ω, ω, 0), and static second-order hyperpolarizability, γ((2))(0; 0, 0, 0), is performed using an auxiliary electric field approach...

BACKGROUND The brown planthopper (BPH) Nilaparvata lugens (Stal) is a serious pest of rice in Asia. Development of novel control strategies can be facilitated by comparison of BPH feeding behaviour on varieties exhibiting natural genetic variation, and then elucidation of the underlying mechanisms of resistance. METHODOLOGY/PRINCIPAL FINDINGS BPH feeding behaviour was compared on 12 rice vari...

In [5] it is shown how a model for the logic of constructible duality is a symmetric monoidal closed category with products, that is, a model of linear logic. Remarkably, Nelson’s strong negation∼ behaves as linear duality ⊥. We compare it with some previous results from [4] regarding stable models in a linear logic setting, and suggest some further lines to explore. 1. From Ncd to linear logic...
