Dedication of the Palomar Observatory and the Hale Telescope

The dedication of the Palomar Observatory, if it were being held in England, would be accompanied by brilliant pageantry both of the state, with its knights, heralds, pursuivants, kings at arms, admirals and captains, and of the church with its bishops, priests and deacons, crucifiers and choirs; and I am sure that we feel the quality of religion in this ceremony. We would hear the choirs chanting in antiphony that great canticle which so delights the choir boys: Benedicite, omnia opera Domini

Effect of vitamin A Injections on Blood and Liver Levels in Cattle Fed Low-Carotene Diets

The objectives of these experiments were twofold, first, to study the effects of length of feeding period and dosage level of injected vitamin A on vitamin A status of steers fed a low carotene finishing rations without supplemental vitamin A, and, second, to study the effect of dosage level of injected vitamin A on liver storage of the vitamin following a period of feeding considered to have resulted in major depletion of prior body stores of the vitamin

Vitamin A Bioptency as Measured by Stores of Vitamin A in Livers of Feedlot Cattle

The objective of these experiments was to evaluate the biological potency of two sources of vitamin A premix differing in freshness when administered to fattening beef cattle. Chemical assays were compared with blood and liver vitamin A content to measure the biopotency of the vitamin

Uniaxial strain control of spin-polarization in multicomponent nematic order of BaFe2_{2}As2_{2}

The iron-based high temperature superconductors exhibit a rich phase diagram reflecting a complex interplay between spin, lattice, and orbital degrees of freedom [1-4]. The nematic state observed in many of these compounds epitomizes this complexity, by entangling a real-space anisotropy in the spin fluctuation spectrum with ferro-orbital order and an orthorhombic lattice distortion [5-7]. A more subtle and much less explored facet of the interplay between these degrees of freedom arises from the sizable spin-orbit coupling present in these systems, which translates anisotropies in real space into anisotropies in spin space. Here, we present a new technique enabling nuclear magnetic resonance under precise tunable strain control, which reveals that upon application of a tetragonal symmetry-breaking strain field, the magnetic fluctuation spectrum in the paramagnetic phase of BaFe$_{2}$As$_{2}$ also acquires an anisotropic response in spin-space. Our results unveil a hitherto uncharted internal spin structure of the nematic order parameter, indicating that similar to liquid crystals, electronic nematic materials may offer a novel route to magneto-mechanical control.Comment: 11 pages, 5 figure

B-T phase diagram of CoCr2O4 in magnetic fields up to 14 T

We have measured the magnetization and specific heat of multiferroic CoCr2O4 in magnetic fields up to 14 T. The high-field magnetization measurements indicate a new phase transition at T* = 5 - 6 K. The phase between T* and the lock-in transition at 15 K is characterized by magnetic irreversibility. At higher magnetic fields, the irreversibility increases. Specific-heat measurements confirm the transition at T*, and also show irreversible behavior. We construct a field-temperature phase diagram of CoCr2O4.Comment: 4 page

Methods of Supplementing Carotene and Vitamin A to Vitamin A-Depleted Sheep

The primary objective of these experiments was to study the effectiveness of different methods of supplementing vitamin A to vitamin A-depleted lambs as measured by growth, blood plasma levels and liver stores of vitamin A. The second objective was to determine effect of oral and injection methods of carotene administration on subsequent vitamin levels in blood plasma, liver, heart and kidney tissue. Responses were monitored over a period of about 4 weeks
