A central issue for researchers of human spatial knowledge, whether focused on perceptually guided action or cognitive-map acquisition, is knowledge of egocentric directions, directions from the body to objects and places. Several methods exist for measuring this knowledge. We compared two particularly important methods, manual pointing with a dial and whole-body rotation (body heading), under ...

The effects of rotation on the evolution of non-Gaussian statistics of velocity increments in rotating turbulence are studied in this paper. Following the Lagrangian evolution of the velocity increments over a fixed distance on an evolving material element, we derive a set of equations for the increments, which provides closed representation for the nonlinear interaction between the increments ...

A comparison between linear stability analysis and observations of pulsation modes in five δ Scuti stars, belonging to the same cluster, is presented. The study is based on the work by Michel et al. (1999), in which such a comparison was performed for a representative set of model solutions obtained independently for each individual star considered. In this paper we revisit the work by Michel e...

Suppose the ground field $$\mathbb{F}$$ is an algebraically closed characteristic of p > 2. In this paper, we investigate restricted cohomology theory Lie superalgebras. Algebraic interpretations low dimensional superalgebra are given. We show that there a family model filiform $$L_{p,p}^\lambda$$ structures parameterized by elements $$\lambda \in {\mathbb{F}^p}$$ . explicitly describe both 1-d...

We present a new approach to the numerical computation of the basic frequencies of a quasiperiodic signal. Although a complete toolkit for frequency analysis is presented, our methodology is better understood as a refinement process for any of the frequencies, provided we have a rough approximation of the frequency that we wish to compute. The cornerstone of this work is a recently developed me...

background: today, in many countries, wastewater treatment plants effluent is an important part of the renewable water resources. in this case, the effluent quality standards are developed and used is important. the aim of this study was to investigate the potential use of wastewater plants effluent restricted irrigation. methods: in this descriptive - analytical study, samples was collected fr...

The high-field (i.e., 94 GHz) membrane EPR spectra of lipids spin labeled in their fatty acid chains have been simulated by using two limiting motional models. The aim was to identify the dynamic origin of the residual (g(xx) - g(yy)) anisotropy observed in the nonaxial EPR spectra of cholesterol-containing membranes. It is concluded that the residual spectral anisotropy arises from in-plane or...

The Drosophila adult male terminalia originate from the genital disc. During the pupal stages, the external parts of terminalia evert from two ventral stalks; the everted left and right dorsal halves fuse at the dorsal midline. At the same time the male terminalia perform a 360 clockwise rotation. Several mutations are known to affect the rotation of the male terminalia, while none is known to ...

background: severe metabolic acidosis occurs during orthotopic liver transplantation (olt) particularly during the anhepatic phase. although nahco3 is considered as the current standard therapy, there are numerous adverse effects. the aim of this study was to determine whether the restricted use of normal saline during anesthesia could reduce the need for nahco3. methods: in this study we enrol...

introduction: the aim of this study was to compare the changes that occur in the danger zone (dz) after preparation of curved mesiobuccal (mb) canals of mandibular first molars with waveone instruments in two different movements [reciprocation (rcp) and counter-clockwise rotation (ccwr)] by means of cone-beam computed tomography (cbct). methods and materials: mb canals of 30 mandibular molars w...
