Introduction: A wide range of oxygen isotopic compositions have been observed in early solar system objects reflecting the existence of heterogeneity in the solar nebula from sub-millimeter to the scale of planetary dimensions. Along with the spread in composition, the striking feature is the departure from the normal fractionation line (represented by a slope 1⁄2 line in a 3-isotope plot of ox...

BACKGROUND Anterior cervical corpectomy and fusion are frequently used in the treatment of cervical spinal disease. However, the range of motion (ROM) of the operative level is unavoidably lost due to fusion. This study aims to establish an anterior cervical corpectomy goat non-fusion model and to evaluate the ROM of adjacent and operative levels. MATERIAL/METHODS Six adult-male goats (in viv...

pseudohandelia tzvel. belongs to the asteraceae family with only one species. it is endemic to khorasan province in iran. having partially big and beautiful inflorescences make it a proper choice in urban green space especially in case of mass culture. in this research, to investigate possibility of micro propagation of this plant two separate experiments were designed. to obtain non contaminat...

iranian oil buy back contract is a kind of service contract that foreign party carries out all operations in development or reconstruction of oil or gas field with its costs. in return, national iranian oil company obliges to compensate contractor all capital or non-capital costs necesserly by produced oil or gas from the same field. the energy charter treaty as the most perfect international t...

the application of the [pd{c6h3(ch2ch2nh2)-4-ome-5-κ2-c,n}(μ-br)]2 complex of 2-methoxyphenethylamine in the heck coupling reaction was considered under both conventional and microwave irradiation conditions, and their results were compared. this complex is an efficient, stable and non-sensitive to air and moisture catalyst for the vinylation of substituted aryl halides with different electroni...

The paper is concerned with the bifurcation of limit cycles in general quadratic perturbations of a quadratic reversible and non-Hamiltonian system, whose period annulus is bounded by an elliptic separatrix related to a singularity at infinity in the poincar'{e} disk. Attention goes to the number of limit cycles produced by the period annulus under perturbations. By using the appropriate Picard...
