(Abridged) We describe here the most ambitious survey currently planned in optical, Large Synoptic Survey Telescope (LSST). A vast array of science will be enabled by a single wide-deep-fast sky survey, and LSST have unique capability faint time domain. The design is driven four main themes: probing dark energy matter, taking an inventory Solar System, exploring transient optical sky, mapping Milky Way. wide-field ground-based system sited at Cerro Pach\'{o}n northern Chile. telescope 8.4 m...
A brief account is given of the accepted view that riboflavin supplements in diet breeding stock lead to improved hatchability and clubbed down specific for a deficiency this vitamin. Attention, however, drawn apparent failure various workers achieve hatching rate with supplemented substantially excess 80% fertile eggs which appears be national average figure. An experiment described range managed received diets at varying levels, lowest which, light available evidence, would sufficient good...
The efficient, safe, and high-performance design operation of nuclear reactors, other systems, rely on complete accurate data files. ENDF/B library is the main reaction in United States one ones world. It encompasses sub-libraries for neutron, proton, alpha, deuteron, 3 He, gamma projectiles, addition to thermal neutron scattering law, fission product yields three atomic sub-libraries. last release was ENDF/B-VIII.0 2018. Since then, many important impactful developments have been made...
We describe work at Lawrence Berkeley National Laboratory (LBNL) to develop enhanced performance, fully depleted, back-illuminated charge-coupled devices for astronomy and astrophysics. The CCDs are fabricated on high-resistivity substrates typically 200–300 μm thick improved near-infrared response. primary research development areas include methods reduce read noise, increase quantum efficiency readout speed, the of fabrication efficient production large focal planes. In terms noise...
The failure of a high proportion fertile eggs to hatch still remains major cause financial loss the poultry industry. Payne (1919) pointed out consistent manner in which embryonic mortality manifested peak periods at fourth day and nineteenth incubation, he drew attention fact that latter period susoeptibility showed an increased level with artificial incubation compared natural methods. Romanoff (1949) summarized explanations put forward account for these two peaks mortality. Riddle (1930)...
LYMPHOMATOSIS in its various manifestations remains the most extensive threat to profitability of poultry keeping. Precise figures numbers fowl dying from this disease are impossible obtain but an estimate that about 25 percent all birds Britain succumb one or other forms lymphomatosis has often been put forward. This figure gains some credence analysis post-mortem examination at main Veterinary Laboratory Ministry Agriculture. During 1952 number carcases which death, ailing condition prior...
THE influence of egg weight on hatching rates has been investigated by numerous workers. There appears to be general agreement that large eggs hatch poorly (Dunn, 1922; Jull and Haynes, 1925; Halbersleben Mussehl, Scott Warren, 1941), but opinion the relative superiority small medium is divided. Warren (1934) Haynes (1925) presented data supporting their view smaller tended at a higher rate than either or eggs. Opposing this conclusion are contentions Axelsson (1932), Dunn (1922) others. But...
We describe the design of Commissioning Instrument for Dark Energy Spectroscopic (DESI). DESI will obtain spectra over a 3 degree field view using 4-meter Mayall Telescope at Kitt Peak, AZ. In order to achieve required image quality this view, new optical corrector is being installed Telescope. The designed characterize system. has five commercial cameras; one center focal surface and four near periphery cardinal directions. There are also 22 illuminated fiducials, distributed throughout...
We describe a system to measure the Quantum Efficiency in wavelength range of 300 nm 1100 40 × mm n-channel CCD sensors for construction 3.2 gigapixel LSST focal plane. The technique uses series instrument create very uniform flux photons controllable intensity interest across face sensor. This allows absolute be measured with an accuracy 1% range. will part production facility at Brookhaven National Lab basic component camera.
THE advice commonly given to a breeder, who is anxious reduce the incidence of lymphomatosis in stock he sells his customers, breed for resistant strain. Hutt and Cole (1948) others have described success accompanying breeding programme based on continuous selection following year’s birds from families disease over first period their lives. Coles (1954) has shown that these endeavours are extremely expensive contended they practicable only with centres having considerable financial...
Reference is made to the depression in hatching rates occasionally recorded when fishmeal fed breeding hens. In a previous communication this was tentatively ascribed presence of aerobic sporing bacteria, support for theory being given by high early death-rate from yolksac infection chicks hatched affected pens. experiment samples white widely separated points origin were employed. With one group birds extreme recorded; other moderate found. Bacterial assays showed that only sample contained...
THE rise of the intensive methods managing poultry during last decade in Great Britain has been associatd with increasing criticism about quality eggs produced under these artificial conditions. It is true that yolks laid by fowl kept confinement are frequently lighter colour than those birds having access to range. This difference is, however, attributable presence xanthophylls which have no nutritional benefit chick embryo or consumer. The darker yolk generally preferred British public...
The Dark Energy Spectroscopic Instrument (DESI) is under construction to measure the expansion history of Universe using Baryon Acoustic Oscillation technique. spectra 35 million galaxies and quasars over 14000 sq deg will be measured during life experiment. A new prime focus corrector for KPNO Mayall telescope deliver light 5000 fiber optic positioners. fibers in turn feed ten broad-band spectrographs. We describe methods results commissioning instrument metrology program. primary goals...
