The relations between ultrastructure and function have been examined in the canine left ventricle under known hemodynamic conditions. Left ventricles of normal dogs were fixed acutely by rapid perfusions of the coronary arteries in either diastole or systole, and also following acute ventricular distension, or potentiation of contraction. Sarcomere lengths at the midwall of the left ventricle a...

We study Dand DF-strings in a D3D̄3 system in the context of Dirac-Born-Infeld type effective field theory. In the presence of an electric flux from a transverse direction, we discuss gravitating thick D-string solutions of a spatial manifold, S2 × R1, in which straight D-strings stretched along the R1 direction are attached to the south and north poles of the two-sphere. There is a horizon alon...

A conventional Bonner Sphere (BS) set consisting of six polyethylene spheres was modified to enhance its response to a high-energy neutron by putting a lead shell inside a polyethylene moderator. The response matrix of an extended BS was calculated using the MCNPX code and calibrated using a 252Cf neutron source. In order to survey the unknown photon and neutron mixed field, a spherical tissue ...

Capillary forces have been measured by atomic force microscopy in the plate-sphere setup between gold, borosilicate glass, GeSbTe, titanium, and UV-irradiated amorphous titanium-dioxide surfaces. The force measurements were performed as a function contact time and surface roughness in the range 0.2-15 nm rms and relative humidity ranging between 2% and 40%. It is found that even for the lowest ...

Crystalline, yet smooth, sphere-like morphologies of small molecular compounds are desirable in a wide range of applications but are very challenging to obtain using common growth techniques, where either amorphous films or faceted crystallites are the norm. Here we show solvent-free, guard flow-assisted organic vapour jet printing of non-faceted, crystalline microspheroids of archetypal small ...

A new means of incorporating radiative transfer into smoothed particle hydrodynamics (SPH) is introduced, which builds on the success of two previous methods the polytropic cooling approximation as devised by Stamatellos et al (2007), and flux limited diffusion (e.g. Mayer et al 2007). This hybrid method preserves the strengths of its individual components, while removing the need for atmospher...

Thick shells have attracted much attention in recent years as intelligent and functional graded materials because of their unique properties. In this review paper, some critical issues and problems in the development of thick shells made from Functionally graded piezoelectric material (FGPM) are discussed. This review has been conducted on various types of methods which are available for thick ...

[abridged] We present new scattered light and millimeter observations of the protoplanetary disk around LkH$\alpha\,330$, using SPHERE/VLT ALMA, respectively. The scattered-light SPHERE reveal an asymmetric ring at 45au from star in addition to two spiral arms with similar radial launching points 90au. ALMA (resolution 0.06''$\times$0.04'') mainly show located 110au star. In this asymmetry, the...

We present a technique to tailor materials for functionally graded (FG) linear elastic hollow cylinders and spheres to attain through-the-thickness either a constant hoop (or circumferential) stress or a constant in-plane shear stress.
