A total of 240 day-old broiler chicks were used to study the effects of phytase on performance and phosphorus (P) excretion from birds fed diets containing low phytate barleys formulated without inorganic P. A positive control based on Harrington barley (HB) was formulated to meet requirements for total P. Three experimental diets, based on either HB (0.39% total P with 0.28% phytate P) or the low phytate varieties LP 422 (0.36% total P with 0.14% phytate P) and LP 955 (0.40% total P with 0.01% phytate P), were formulated to be below requirements for total P by removing all the inorganic P from the diet. The four diets were fed with and without 1,000 FTU/kg phytase. Apparent P digestibility was significantly higher (p<0.01) for birds fed the low phytate barleys than for birds fed HB either supplemented or un-supplemented with inorganic P. P excretion was significantly lower (p<0.01) for birds fed HB without inorganic P than with inorganic P. P excretion was further reduced by the use of the low phytate barleys LP 422 and LP 455 (p<0.01). Phytase supplementation did not affect P excretion (p = 0.39). Body weight gain and feed intake were highest for birds fed the HB diet with inorganic P and lowest for birds fed the HB diet without inorganic P (p<0.01). Among the three low P diets, body weight gain and feed intake of broilers increased as the level of phytate in the barley declined (p<0.01). Phytase modestly increased body weight gain (p = 0.08) and feed intake (p = 0.04). The overall results of this study indicate that it may be possible to reduce the amount of inorganic P used when formulating diets with low phytate barley compared with the levels needed when formulating diets with normal phytate barley. However, it is not possible to completely replace the inorganic P in diets containing low phytate barley without impairing poultry performance. Feeding diets devoid of supplementary inorganic P in combination with low phytate barley resulted in a significant reduction in P excretion by poultry.
The Soviet Union's economic and political implosion ... the fate of North Korea?
Will Sung Yang 한국국방연구원 2008 The Korean Journal of Defense Analysis Vol.20 No.2
This paper examines the outlook for North Korea's economic and political future. It argues that North Korea will most probably meet its demise in the same way as did the former Soviet Union. That is, an economic implosion will occur causing the political collapse of North Korea. Contrary to popular belief that North Korea would sustain itself if it reformed its economic policies, this paper argues that, regardless of reform, North Korea will not be able to avoid the collapse of the state*and the Kim regime, for that matter. The only impact reform will have is with regard to time as it will merely delay the process of North Korea's collapse. The author wishes to stress that these assessments of North Korea's future will probably show a greater impact after Kim Jong Il has passed. It is unlikely that North Korea or the regime will collapse under Kim Jong Il's reign because his regime still has a strong authoritative grip over his state, which he controls by being the commander of the North Korean People's Army and various paramilitary apparatuses, and by control of the media. However, the decisions that Kim Jong Il makes now will be the indirect cause of various unintended consequences in the future. Once the economy of North Korea develops core values that are somewhat similar to the South's, it is highly likely that Seoul, with its economic leverage, will gain political leverage over Pyongyang. This will ultimately have its effects in reunifying the Korean peninsula under Seoul's terms after Kim Jong Il's passing. The author reiterates that both, the status quo or the reform option, will eventually lead to the North's collapse. The difference will be in regard to when.
THE SDSS-IV EXTENDED BARYON OSCILLATION SPECTROSCOPIC SURVEY: OVERVIEW AND EARLY DATA
Dawson, Kyle S.,Kneib, Jean-Paul,Percival, Will J.,Alam, Shadab,Albareti, Franco D.,Anderson, Scott F.,Armengaud, Eric,Aubourg, É,ric,Bailey, Stephen,Bautista, Julian E.,Berlind, Andreas A.,Bers American Astronomical Society 2016 The Astronomical journal Vol.151 No.2
<P>In a six-year program started in 2014 July, the Extended Baryon Oscillation Spectroscopic Survey (eBOSS) will conduct novel cosmological observations using the BOSS spectrograph at Apache Point Observatory. These observations will be conducted simultaneously with the Time Domain Spectroscopic Survey (TDSS) designed for variability studies and the Spectroscopic Identification of eROSITA Sources (SPIDERS) program designed for studies of X-ray sources. In particular, eBOSS will measure with percent-level precision the distance-redshift relation with baryon acoustic oscillations (BAO) in the clustering of matter. eBOSS will use four different tracers of the underlying matter density field to vastly expand the volume covered by BOSS and map the large-scale-structures over the relatively unconstrained redshift range 0.6 < z < 2.2. Using more than 250,000 new, spectroscopically confirmed luminous red galaxies at a median redshift z = 0.72, we project that eBOSS will yield measurements of the angular diameter distance d(A)(z) to an accuracy of 1.2% and measurements of H(z) to 2.1% when combined with the z > 0.6 sample of BOSS galaxies. With similar to 195,000 new emission line galaxy redshifts, we expect BAO measurements of d(A)(z) to an accuracy of 3.1% and H(z) to 4.7% at an effective redshift of z = 0.87. A sample of more than 500,000 spectroscopically confirmed quasars will provide the first BAO distance measurements over the redshift range 0.9 < z < 2.2, with expected precision of 2.8% and 4.2% on d(A)(z) and H(z), respectively. Finally, with 60,000 new quasars and re-observation of 60,000 BOSS quasars, we will obtain new Lya forest measurements at redshifts z > 2.1; these new data will enhance the precision of d(A)(z) and H(z) at z > 2.1 by a factor of 1.44 relative to BOSS. Furthermore, eBOSS will provide improved tests of General Relativity on cosmological scales through redshift-space distortion measurements, improved tests for non-Gaussianity in the primordial density field, and new constraints on the summed mass of all neutrino species. Here, we provide an overview of the cosmological goals, spectroscopic target sample, demonstration of spectral quality from early data, and projected cosmological constraints from eBOSS.</P>
