The structure and phase evolution of nanocrystalline Ce(1-x)Ln(x)O(2-x/2-delta) (Ln = Yb, Lu, x = 0 - 1) oxides upon heating in H(2) was studied for the first time. Up to 950 degrees C the samples were single-phase, with structure changing smoothly with x from fluorite type (F) to bixbyite type (C). For the Lu-doped samples heated at 1100 degrees C in the air and H(2), phase separation into coe...

Left-handed female subjects, categorized as using an inverted (LI) (n=7) or non-inverted (LN) (n=7) writing posture, were compared on performance of a motor task. Task parameters were manipulated to create four conditions varying in demand for sequential processing. Based on previously observed group differences in the direction and extent of hemispheric lateralization, non-inverted writers wer...

background: respiratory problems are common after long bone fractures. the objective of the present investigation is to evaluate the effect of early fixation of femoral shaft fracture on the incidence of respiratory problems.   methods: the results of early and late stabilization of femoral shaft fractures were studied in 150 patients. the patients were divided into two groups according to the ...

Four supergiant and numerous giant gasfields have been discovered in the Southwest Iran which produce from Permian-Triassic carbonates belong to the upper member of Dalan Formation and Kangan Formation. In this research a detailed biostratigraphic, microfacies and sequence stratigraphic study of the late Middle Permian to Triassic successions was undertaken from 850 thin sections prepared from ...

Mainly used compilers are based on separate compilation, whereas optimizations of object-oriented programs mostly need a complete knowledge of the whole program. This is especially the case for type analysis and late binding implementations. Both approaches have pros and cons. Therefore, this paper proposes an integration of global optimizations in a separate compilation framework. The code gen...

Recent Semantic Space Models (SSMs) are now integrating perceptual information with linguistic statistics into a unified mental space, offering a solution to the criticism that SSMs are disembodied. However, these new models introduce the problem of illusory feature migrations. When the word dog is perceived, its perceptual features should migrate to hyena, so the system can infer the perceptua...

Lattice energies ΔLHθ of lanthanide orthophosphates, LnPO4 (Ln=Ce-Lu, excluding Pm) have been determined from the Born-Haber cycle and compared with those calculated by other methods. The Born-Haber cycle results in close values of ΔLHθ to those obtained after an empirical equation proposed by Glasser and Jenkins. It has been found that: (i) the partial derivative of the lattice enthalpies to t...

abderaz formation is one of the upper cretaceous formations in the kopet-dagh sedimentary basin. a stratigraphic section from the mentioned formation is selected for detailed systematic description with regard to echinoids. numerous well preserved representatives of the families mircrasteridae wright, 1857 and echinocorythidae lambert, 1920 are described from the ghaleh-zoo stratigraphic sectio...

Let Xn = (xij) be an n by p data matrix, where the n rows form a random sample of size n from a certain p-dimensional population distribution. LetRn = (ρij) be the p×p sample correlation matrix ofXn; that is, the entry ρij is the usual Pearson’s correlation coefficient between the ith column of Xn and jth column of Xn. For contemporary data both n and p are large. When the population is a multi...
