Material characterization of structural adhesives in the lap shear mode

A general method for characterizing structual adhesives in the bonded lap shear mode is proposed. Two approaches in the form of semiempirical and theoretical approaches are used. The semiempirical approach includes Ludwik's and Zhurkov's equations to describe respectively, the failure stresses in the constant strain rate and constant stress loading modes with the inclusion of the temperature effects. The theoretical approach is used to describe adhesive shear stress-strain behavior with the use of viscoelastic or nonlinear elastic constitutive equations. Two different model adhesives are used in the single lap shear mode with titanium adherends. These adhesives (one of which was developed at NASA Langley Research Center) are currently considered by NASA for possible aerospace applications. Use of different model adhesives helps in assessment of the generality of the method

High-precision gravimetric survey in support of lunar laser ranging at Haleakala, Maui, 1976 - 1978

The planning, observations and adjustment of high-precision gravity survey networks established on the islands of Maui and Oahu as part of the geodetic-geophysical program in support of lunar laser ranging at Haleakala, Maui, Hawaii are described. The gravity survey networks include 43 independently measured gravity differences along the gravity calibration line from Kahului Airport to the summit of Mt. Haleakala, together with some key points close to tidal gauges on Maui, and 40 gravity differences within metropolitan Honolulu. The results of the 1976-1978 survey are compared with surveys made in 1961 and in 1964-1965. All final gravity values are given in the system of the international gravity standardization net 1971 (IGSN 71); values are obtained by subtracting 14.57 mgal from the Potsdam value at the gravity base station at the Hickam Air Force Base, Honolulu

Food Habits of Deer In The Southern Black Hills As Determined By The Point Technique

White-tailed (Odocoileus virginianus) and mule deer (Odocoileus hemionius) were collected in 1968 and 1969 for a study of food habits. Rumen contents were analyzed by use of the point-analysis technique and weights. This is the first food habits study from the southern Black Hills and is necessary for proper deer management. To evaluate the suitability of the point technique for Black Hills vegetation, an artificial population was constructed from known weights of a forb, (Achillea lanulosa), grass (Oryzopsis asperfoliz), rose (Rosa sp.), kinnikinnick (Arctostaphylos uva-ursi), and ponderosa pine (Pinus ponderosa). Each population was tested with 100-point trails and 200-point trials. Comparisons of point percentages to weight percentages were: forb – 24.3 to 14.8, grass – 26.5 to 25.7, rose – 10.2 to 10.8, kinnikinnick – 24.8 to 29.3, and pine – 16.3 to 18.3 percent. Forb estimates were significantly different (P\u3e0.05) using chi-square analysis. Browse, grasses and forbs were estimated with no significant differences (P\u3e0.05) using chi-square analysis: forbs 0 24.3 to 14.8, grasses – 26.5 to 25.7 and browse 51.3 to 58.4 percent. Twenty stomach samples were separated by hand after point analysis. Estimates of relative composition by hand separation and point for ten major species were: mountain mahogany (Cercocarpus montanus), 15.2 to 13.7; ponderosa pine, 12.3 to 13.9; juniper (Juniperus spp.), 9.6 to 12.8; grasses, 9.4 to 10.3; kinnikinnick, 7.4 to 9.6; snowberry (Symphoricarpos spp.), 5.2 to 7.3; rose, 5.1 to 5.7; Oregon grape (Mahonia repens), 3.9 to 5.5; bedstraw (Calium sp.), 2.5 to 4.7; and old-man’s bead (Usnea sp.), 4.2 to 3.8 percent. Paired-“t” tests showed there was no significant difference (P\u3e0.05) between the estimated relative composition either by hand separation or by points. No difference in estimation of the hand-separated material: forbs, 11.9 to 17.9; grasses, 9.4 to 10.3; and browse, 69.1 to 58.7 percent. Analysis of 52 rumen samples collected in the fall showed kinnikinnick, grasses, Oregon grape, snowberry (Symphoricarpos spp.), and forbs to be important food species. Analysis of 64 rumen samples collected in the winter indicated that poinderosa pine, mountain mahogany, and common juniper (Juniperus communis) were the most important food species. Other winter foods of importance were kinnikinnick, fobs, grasses, snowberry, and Rocky Mountain juniper (Juniperus scopulorum). Point analysis of content in nine rumen collected in the summer showed that alfalfa (Medcago sative), clover (Trifolium pretense), grasses and forbs were the most important foods

Muon spin rotation and relaxation in the superconducting ferromagnet UCoGe

We report zero-field muon spin rotation and relaxation measurements on the superconducting ferromagnet UCoGe. Weak itinerant ferromagnetic order is detected by a spontaneous muon spin precession frequency below the Curie temperature $T_C = 3$ K. The $\mu^+$ precession frequency persists below the bulk superconducting transition temperature $T_{sc} = 0.5$ K, where it measures a local magnetic field $B_{loc} = 0.015$ T. The amplitude of the $\mu$SR signal provides unambiguous proof for ferromagnetism present in the whole sample volume. We conclude ferromagnetism coexists with superconductivity on the microscopic scale.Comment: 4 pages, 3 figures, accepted for publication in PR
