... However, to avoid excessive central obscuration, a conical baffle is necessary in addition to the usual primary and secondary baffles. ... At that time, it was complete except several outside ribs remained to be attached and the upper and lower edges needed to be chamferred. ... The cone was measured at four equally spaced locations very near its upper and lower edge (Table 3). ... A tape measure was used to measure four diameters of the baffle at its upper and lower edges (Table 4). ...

... Some wonder if smaller wheels have less inertia and therefore give greater acceleration, while others believe that the smaller wheel has to spin faster, so it is a wash. ... The kinetic energy in the wheel is a measure of how much energy you've spent just getting the wheel to spin rather than investing that energy into the road. ... Larger wheels have less rolling resistance, for several reasons. ... So how much difference does the lower inertia of smaller wheels really make? ...

... 1) The MS lower envelopes for groups of stars with different metallicities turn out to be coincident. ... 4) The conformation of the kinematics of stars within narrow ranges ob b-y with the ages derived from isohrones reveals that, at Z < Z , the isohrone ages seem to be increasingly overestimated with growing b-y . ... At a given metallicity, they have a much narrower MS and the locus of their MS lower envelope seems to be brighter for the metal-rich group of stars. ...

... Concept Spacecraft . ... The proposed lentiular design concept for the Apollo spacecraft was one of several unorthodox designs rejected in favour of the more familiar conical shape which was lighter and less complex.The lenticular design was a ?road not taken?, losing out to less challenging configurations.It is strange to think that if history had proceeded differently, each Apollo crew could have ended their lunar mission by gliding to a touchdown on a runway at Edwards AFB in a flying saucer! ...

Growth of Epitaxial (001) YBa2Cu3O7 Superconducting Thin Films on (001) Diamond Substrate. ... In order to reach higher frequencies and lower losses, it is necessary to use substrate material with lower dielectric constants and low losses in far infrared region. ... In the present work, as a first step in this direction, we present results of successful growth of epitaxial (001)YBa2Cu3O7 thin film on (100) diamond substrate by pulse laser deposition method. ...

Let K be a global field. ... The real number $\gamma_K = c_0/c_{-1}$ is called the Euler-Kronecker constant of the field $K$. In the article of Yasutaka Ihara "On the Euler-Kronecker constants of global fields and primes with small norms" the lower bound $\gamma_K\ge-\log\sqrt{|d|}$ is obtained, where $d$ is the discriminant of the field $K$. In my talk I will prove the lower bound $\gamma_K\ge -\left(1-\frac{\sqrt{5}}{5}\right) \log\sqrt{|d|}$. ...

. The lower mirage. The lower mirages occur when the air layers at the Earth surface are so hot (for example in deserts), that the light beams coming from the object are greatly twised. Drawing the arch they are coming upwards. Thus we can see houses and trees as it reflected in the water. In reality they are the transformed images of far away landscapes. The lower mirages may be seen even on the burning hot hard-surface road. Back .

... The chances of the Earth being hit by a comet from beyond Pluto — А la Armageddon — are much lower than previously thought, according to new research by an ANU astronomer. ... I calculate that small comets, capable of destroying a city, only hit the Earth once every 40 million years or so,” Dr Francis said. ... But asteroids and short-period comets come past again and again, so if we’re clever enough we can find them all and predict which, if any, will hit the Earth,” said Dr Francis. ...

... This paper presents an algorithm for solving antenna based polarization leakage in a radio interferometer using co-polar observations of unpolarized sources. If ignored, polarization leakage manifests itself as closure errors in parallel hand (co-polar) visibilities. ... Hence, polarization leakage manifests as increased closure errors . ... The closure phase due to polarization mis-matches between phased antennas in a radio interferometer therefore naturally measures the Pancharatnam phase. ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...
