Starches from two ecotypes of achira roots (Canna edulis Ker-Gawler) were characterized and compared to commercial potato and corn starches. This included scanning electron microscopy (SEM) of starch granules and amylose content determination of starch. Starch solutions or gels were tested by rotational viscometry, Rapid Visco Analyzer (RVA), and texture analysis. Some starch samples were subje...

Rotating beams have been considerably appealing to engineers and designers of complex structures i.e. aircraft’s propeller and windmill turbines. In this paper, a new flexibility-based method is proposed for the dynamic analysis of rotating non-prismatic Euler-Bernoulli beams. The flexibility basis of the method ensures the true satisfaction of equilibrium equations at any interior point of the...

Abstract The statistical shape analysis called Procrustes minimizes the Frobenius distance between matrices by similarity transformations. method returns a set of optimal orthogonal matrices, which project each matrix into common space. This manuscript presents two types distances derived from for exploring between-matrices similarity. first one focuses on residuals analysis, i.e., residual-bas...

Under the entrywise dominance partial ordering, T.L. Markham and R.L. Smith obtained a Schur complement inequality for the Hadamard product of two tridiagonal totally nonnegative matrices. Applying the properties of the Hadamard core of totally nonnegative matrices, the Schur complement inequalities for the Hadamard product of totally nonnegative matrices is obtained, which extends those of T.L...

In the context of computed tomography (CT), iterative image reconstruction techniques are gaining attention because high-quality images are becoming computationally feasible. They involve the solution of large systems of equations, whose cost is dominated by the sparse matrix vector product (SpMV). Our work considers the case of the sparse matrices being block circulant, which arises when takin...

A calculation of ultracold neutron ~UCN! upscattering rates in molecular deuterium solids has been carried out, taking into account intramolecular excitations and phonons. The different molecular species ortho-D2 ~with even rotational quantum number J! and para-D2 ~with odd J! exhibit significantly different UCN-phonon annihilation cross sections. Parato ortho-D2 conversion, furthermore, couple...

Advanced bioreactors are essential for meeting the complex requirements of in vitro engineering functional skeletal tissues. To address this need, we have developed a computer controlled bench-top bioreactor system with capability to apply complex concurrent mechanical strains to three-dimensional matrices independently housed in 24 reactor vessels, in conjunction with enhanced environmental an...

The consequences of rotational-symmetry breaking in Heisenberg spin-glasses are studied with use of order parameters which are time-dependent SO(3) rotation matrices. A microscopic derivation of the hydrodynamic "triad" theory, including the effect of small magnetic fields and random anisotropies, is presented. In the mean-field limit the finitetime exchange stiffness and macroscopic anisotropy...

Sixty-two patients with femoral fractures treated conservatively have been studied over an interval of 1 to 6 years. Rotational deformity was assessed by a radiological method of anteversion measurement. The degree of rotational deformity following fracture ranged from 10 degrees to 33 degrees in just over one-third of the whole group; by later assessment there was no evidence of spontaneous co...
