Collagen fibrils generated in vitro at 37 degrees C by enzymic removal of C-terminal propeptides from type I pC-collagen (an intermediate in the normal processing of type I procollagen to collagen containing the C-terminal propeptides but not the N-terminal propeptides) display shape polarity, with one tip fine tapered and the other coarse tapered. Mass measurements by scanning transmission ele...

Abstract The reflector on an impulse radiating antennas (IRAs) is normally designed to be paraboloidal in shape, and are oriented so that the electrical feed point of the TEM feed line coincides with the focal point of the paraboloid. In many practical cases, the feed point and focal points are not exactly aligned, producing some defocus of the reflector. There are two types of defocus that can...

The study of a real function of two real variables can be supported by visualization using a Computer Algebra System (CAS). One type of constraints of the system is due to the algorithms implemented, yielding continuous approximations of the given function by interpolation. This often masks discontinuities of the function and can provide strange plots, not compatible with the mathematics. In re...

The two-dimensional shallow water equations in Lagrangian coordinates are considered. Lie group classification for the class of elliptic paraboloid bottom topography is performed. transformations mapping with a plane or rotation symmetric into gas dynamics polytropic exponent γ=2 represented. foliation discussed. New invariant conservative finite-difference schemes and their one-dimensional red...

We study the Ricci flow starting at an SU(2) cohomogeneity-1 metric $g_{0}$ on $\mathbb{R}^{4}$ with monotone warping coefficients and whose restriction to any hypersphere is a Berger metric. If has bounded Hopf-fiber, curvature controlled by size of orbits opens faster than paraboloid in directions orthogonal then converges Taub-NUT $g_{\mathsf{TNUT}}$ Cheeger-Gromov sense infinite time. also ...

Desain pencahayaan merupakan salah satu prioritas dalam merancang bangunan gedung dan pemanfaatan alami dapat menurunkan pemakaian energi, namun perlu memperhatikan produktifitas kerja pengguna ruang dengan mempertimbangkan rekomendasi standard iluminasi (level of illuminance), kesilauan(glare), tingkat kecermelangan (brightness) efek penghawaan (thermal). Gedung Menara Phinisi Universitas Nege...

CAPS is an integrated system of navigation and communication. The orbit position AsiaSat-3S satellite has been pushed from 105.5E to 147.5E. It become a SIGSO satellite, which plays certain role in improving the constellation DOP system. According characteristic parameters (mainly including parameters, polarization frequency offset etc.), this paper expounds changes azimuth, elevation angle 16-...
