Sphalerons in Two Higgs Doublet Theories

We undertake a comprehensive investigation of the properties of the sphaleron in electroweak theories with two Higgs doublets. We do this in as model-independent a way as possible: by exploring the physical parameter space described by the masses and mixing angles of the Higgs particles. If there is a large split in the masses of the neutral Higgs particles, there can be several sphaleron solutions, distinguished by their properties under parity and the behaviour of the Higgs field at the origin. In general, these solutions appear in parity conjugate pairs and are not spherically symmetric, although the departure from spherical symmetry is small. Including CP violation in the Higgs potential can change the energy of the sphaleron by up to 14 percent for a given set of Higgs masses, with significant implications for the baryogenesis bound on the mass of the lightest Higgs

Seasonal Variations of the In Vitro Dry-Matter Digestibility of Three Sandhill Grasses

Investigation of the seasonal variation of in vitro dry-matter digestibility of forage of three range grasses was completed. The in vitro dry-matter digestibility declined in all grasses with advance in maturity. Crude protein content declined with advance in maturity and was more highly correlated with dry-matter digestibility than was lignin. Predicted digestibility based on Van Soest's summative equations seemed unrealistically high for forage collections made in late season. No consistent or significant variations in cell-wall constituents or acid-detergent fiber were measured.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.

Nature of Phytomer Growth in Blue Grama

The pattern and relative growth rates of the individual phytomers of blue grama were determined. A mature blue grama shoot from the site had an average of 13 complete phytomers. The first six phytomers appeared to be initiated in the growing season prior to the one in which the plant reached maturity. Internodal elongation of over 100 mm in a period of two weeks was not uncommon. In most instances the internodes did not elongate before the sheath and blade reached maximum length. The leaf of the last phytomer was initiated just prior to the middle of June. Mature sheath length varied from 15 mm in phytomer 13 to nearly 80 mm in phytomers 11 and 12. Blade length varied from 4 mm in phytomer 2 to 134 mm in phytomer 10.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.

Effects of Temperature and Daylength on Axillary Bud and Tiller Development in Blue Grama

A study was conducted to determine the nature of tiller development and the influence of light and temperature on growth and development of the axillary buds and tillers of blue grama. An axillary bud, enclosed in a prophyllum was found at each node of the culm. The development of the axillary bud into a tiller is a function of temperature. Controlled increase of temperatures in early spring increased the rate of axillary bud and tiller development in blue grama. The data also indicate that controlled reduction in length of photoperiod decreased the growth of axillary buds and development of tillers.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.

The Influence of Ammonium Nitrate on the Control of Mesquite Resprouts with 2,4,5 T Ester

The influence of ammonium nitrate on the phytotoxicity of 2,4,5-T ester, nitrogen concentration, and niacin concentration of honey mesquite was studied. Fertilizer was applied to individual 3-year-old resprouts in the fall of 1973 and 2,4,5-T ester was applied to the individual 3-year-old resprouts on 3 dates in 1974. There was no conclusive evidence that N fertilizer affected the percentage of root-kill of mesquite when sprayed with 2,4,5-T ester. Ammonium nitrate had no effect on the nitrogen or the niacin levels in honey mesquite.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.

Seasonal and Livestock Influences in Estimating Foliage Density of Vegetation

A knowledge of the influence of advance in season and activity of grazing animals on foliage-density estimates is necessary to properly assess trends or evaluate range treatments. Foliage-density estimates were made at 14-day intervals from June 20 through August 17 of the years 1964 and 1965 at the Scotts Bluff Experimental Range. Significant differences were found in foliage densities of various species among dates of sampling. These differences varied between years of the study. Grazing and trampling of livestock had little effect on foliage-density estimates. Optimum time for estimating foliage density of mixed-prairie vegetation was established as being the period one week prior to and one week following July 20. Grazing influences did not alter these dates.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
