The Effect of Changing Temperatures on Hardiness, Respiration, and Intensity of Rest of Dormant Peach and Apricot Buds

studies were conducted to better understand the influence of temperature on the rest period of dormant peach and apricot buds. Gleason Elberta peach and Chinese apricot trees in the field at Howell Experiment Station in Ogden were used to evaluate rest intensity, respiration, and cold hardiness in relation to temperature. A rest intensity curve was obtained for both species using various concentrations of gibberellic acid. It was found that temperature had no direct effect on the depth of rest and that the depth of rest had no measurable influence on respiration and cold hardiness. Respiration of flower and leaf buds was not affected by temperature until after the rest period was over and the temperature rose above 40 F. However, cold hardiness was directly affected by temperature during the rest period. As the temperatures dropped the cold hardiness increased in both species. Lovell peach seedlings were placed in 5 gallon containers and placed in controlled temperature chambers. At 3 different periods, 3 trees were removed from 9 different temperature treatments. It was found that 40 F was generally more effective in breaking rest than was 32 F. Light did not seem to affect the rest period significantly

Should the Utah Law as it Applies to Inheritance be Modified?

In the United States, until recently, the inheritance tax has been employed principally as a war measure. The first one imposed was the stamp act of July 6, 1797, which was repealed five years later. The war revenue act of July 1, 1862, was repealed July 14 1870. The revenue act of August 27, 1894 was declared unconstitutional because of its income tax feature. The war revenue act of June 13, 1989 was repealed April 13, 1902. The present federal estate tax was formed September 8, 1916. It was later amended March 3, 1917, and was altered appreciably in the revenue act of October 3, 1917. The amendment increased the rates of the tax. The revenue acts of 1918, 1921, and 1924 changed the rates in varying ways and also changed many of the fundamental provisions. The revenue act of 1926, however, contains a retroactive provision which has the effect of nullifying the rates of the 1924 act and makes the rates of the 1921 act applicable until the effective date of the act of 1926 after which lower rates apply

Central galaxy growth and feedback in the most massive nearby cool core cluster

We present multi-wavelength observations of the centre of RXCJ1504.1-0248 - the galaxy cluster with the most luminous and relatively nearby cool core at z~0.2. Although there are several galaxies within 100 kpc of the cluster core, only the brightest cluster galaxy (BCG), which lies at the peak of the X-ray emission, has blue colours and strong line-emission. Approximately 80 Msun/yr of intracluster gas is cooling below X-ray emitting temperatures, similar to the observed UV star formation rate of ~140 Msun/yr. Most star formation occurs in the core of the BCG and in a 42 kpc long filament of blue continuum, line emission, and X-ray emission, that extends southwest of the galaxy. The surrounding filamentary nebula is the most luminous around any observed BCG. The number of ionizing stars in the BCG is barely sufficient to ionize and heat the nebula, and the line ratios indicate an additional heat source is needed. This heat source can contribute to the H\alpha-deduced star formation rates (SFRs) in BCGs and therefore the derived SFRs should only be considered upper limits. AGN feedback can slow down the cooling flow to the observed mass deposition rate if the black hole accretion rate is of the order of 0.5 Msun/yr at 10% energy output efficiency. The average turbulent velocity of the nebula is vturb ~325 km/s which, if shared by the hot gas, limits the ratio of turbulent to thermal energy of the intracluster medium to less than 6%.Comment: 15 pages, 11 figures, MNRAS in press.
