Just as skeletal characteristics provide clues regarding behavior of extinct vertebrates, phylogenetically-informed evaluation of endocranial morphology facilitates comparisons among extinct taxa and extant taxa with known behavioral characteristics. Previous research has established that endocranial morphology varies across Aves; however, variation of those systems among closely related specie...

Among the most striking aspects of the movement of many animal groups are their sudden coherent changes in direction. Recent observations of locusts and starlings have shown that this directional switching is an intrinsic property of their motion. Similar direction switches are seen in self-propelled particle and other models of group motion. Comprehending the factors that determine such switch...

In the present innovative pursuit, the generalized Nörlund summability method, that is, the (N, c, d) summation process of Fourier series of f (x) as well defined by Borwein [4] has been invoked to approximate the function f (x) belonging to Lip M α (0 < α < 1 ) and M being some constant. Here it is worth-emphasising that not only mere approximation, but also the constants appeared in the proce...

In this paper we focus on an existence of a weak solution to a system describing a self-propelled motion of a single deformable body in a viscous compressible fluid which occupies a bounded domain in the 3 dimensional Euclidean space. The considered governing system for the fluid is the isentropic compressible Navier-Stokes equation. We prove an existence of a weak solution up to a collision.

ÐConsider a hypercube of 2 points described by n Boolean variables and a subcube of 2 points, m n. As is well-known, the Boolean function with value 1 in the points of the subcube can be expressed as the product (AND) of nÿm variables. The standard synthesis of arbitrary functions exploits this property. We extend the concept of subcube to the more powerful pseudocube. The basic set is still co...

In this paper, some new properties of the fundamental solution to the multi-dimensional 1 spaceand time-fractional diffusion-wave equation are deduced. We start with the Mellin-Barnes 2 representation of the fundamental solution that was derived in the previous publications of the 3 author. The Mellin-Barnes integral is used to get two new representations of the fundamental solution 4 in form o...

Wave-propelled boats utilize submerged flapping foils to convert wave energy directly into propulsion. For platforms that are solely propelled using foils, predicting the forward speed is challenging as it time varying and dependent on coupled responses of wave-induced hull motions (surge, heave, pitch) foil motion (driven by incident wavy flow). To ascertain free-running response wave-propelle...

using a wide range of techniques, including differential scanning calorimetry, x-ray diffraction, rapid visco analyser and fourier transform infera red spectroscopy, some physicochemical properties of the starch fraction of six iranian rice cultivars (tarom, tarome hashemi, neda, ramezani, fajr and kamfirouzi) [1]were studied and compared. dsc data showed that starch granules of different rice ...

A study on the preparation of rice bran-based activated carbon was conducted, with and without an acid treatment step prior the activation process. The influence of the activation time on the structure of the activated carbons was evaluated. The acid treatment had a significant positive influence on sorption properties. The rice bran-activated carbon presented a BET surface area of 652m(2)g(-1)...

We aimed to evaluate the radioprotective effect of hydrolyzed rice bran (HRB) on acute gastroenteritis due to chemoradiotherapy for treatment of cervical cancer. This placebo-controlled, double-blind study was conducted as an exploratory investigation of the colitis-inhibiting effects of HRB in alleviating acute-phase gastrointestinal side effects of chemoradiotherapy. The study involved 20 pat...
