Natural History Specimen Collections
The Fish Collection described in this document was transferred in 1992 to the Fish Collection of the University of Texas at Austin in Austin (at that time administratively in the Texas Memorial Museum, but at the time of publication of this digital version of the document it is one (https://biodiversity.utexas.edu/resources/collections/ichthyology) of the Biodiversity Collections in the University's Biodiversity Center (https://biodiversity.utexas.edu/). Thus, the data on the specimens in the Fish Collection described here are now included in the data published to GBIF (https://www.gbif.org/dataset/6080b6cc-1c24-41ff-ad7f-0ebe7b56f311) and other global biodiversity data aggregators by the UT Biodiversity Center's Fish Collection. The same data are also included in the Fishes of Texas Project (http://fishesoftexas.org - Hendrickson, Dean A., and Adam E. Cohen. 2015. âFishes of Texas Project Database (Version 2.0)â doi:10.17603/C3WC70).
Some of the UTMSI Fish Collection specimens remained at the UT Marine Science Insitute on long-term loan from 1992 until sometime in 2017 when the MSI disposed of all remaining specimens (including also Invertebrates). Some were disposed of by a professional HazMat company, but many were apparently taken to the Smithsonian Institution's (USNM) division of Invertebrate Biology. The fate of fish specimens, however, remains unresolved, but the Ichthyology Division at USNM had no knowledge of them at the time this report was archived here.
Dean A. Hendrickson, Curator of Ichthyology, UT Austin, May 1, 2019The University of Texas Marine Science Institute, Port Aransas Marine Laboratory, Natural History Collection of Marine Organisms was initiated in the mid-1940's. Since that time specimens have been added from studies in the Gulf of Mexico, associated estuaries, and marine-influenced terrestrial habitats, with emphasis on the Texas and Mexico coasts. These studies were the baseline surveys for this area and have resulted in the collection of valuable marine organisms. The collection now holds approximately 5,000 catalogued specimens including all forms of biota, vertebrates, invertebrates, algae and flowering plants.
The collection includes the marine fish and invertebrate specimens of the Texas Parks & Wildlife Department, incorporated into the UTMSI-PAML collection in 1976. This state collection, numbering 3,000, is composed primarily of Texas Gulf coast species of fish and invertebrates, representing baseline surveys conducted by the state fisheries biologists. With this collection are card catalogues by specimen number and phylogenetic order.
Other collections incorporated are those from R/V Oregon cruises (U.S. Fish & Wildlife Service, Bureau of Commercial Fisheries, exploratory fishing vessel), H. H. Hildebrand's faunal surveys of the brown and pink shrimp grounds , Whitten et al.'s faunal survey of Texas coast jetties , J. W. Hedgepethâs specimens collected during numerous faunal surveys, tide trap studies, and vegetation and algal surveys. Noteworthy studies from which specimens have been added to the collection are listed in Table 1.
The museum collection is housed in an air-conditioned building in a room specifically designed for this collection. The present facility contains 924 square feet with 1089 square feet of shelf space, which can be trebled to accommodate BLM collections. There are at present 32 1' x 12' shelves, totaling 384 square feet; 194 18" x 12-1/2" shelves, totaling 303 square feet; and 120 11-1/2" x 42" shelves, totaling 402 5 square feet.
The collection is a working museum open to the scientific community; specimens are available on loan to members of this community. Specimens may be used by visiting researchers, graduate-level students, professors, and classes. Attached is an invoice form, "Invoice of Specimens" - a standard form used for loan of collection items.
The Port Aransas Marine Laboratory is committed to the continuing curation of specimens and will continue to provide the supplies necessary to maintain the natural history specimen collections. The University of Texas Marine Science Institute, Port Aransas Marine Laboratory is willing to incorporate the Bureau of Land Management collection into its collection. Funding is requested from BLM to obtain and incorporate all archived BLM specimens from the S.T.O.C.S. survey into the collection.Integrative Biolog
Electron capture to continuum in collisions of bare projectiles with Ne targets
Abstract. We have investigated the cusp resulting from electron capture to the continuum of 1.25-5 MeV m u- ' fully stripped hydrogen and oxygen as a function of the collision energy and the detector angular resolution B o. It is revealed that the characteristic cusp shape parameters depend strongly on the experimental resolution. Our experimental data are "pared with the second-order Born theory and the impulse approximation. Both theories mnhrm the 8, dependence of the shape parameters and gjve a reasonable descrip-lion of the cusp asymmetry. However, theory tends to overestimate the absolute cross sections, in particular in the case of oxygen. 1
Testing of UH-60A helicopter transmission in NASA Lewis 2240-kW (3000-hp) facility
The U.S. Army's UH-60A Black Hawk 2240-kW (3000-hp) class, twin-engine helicopter transmission was tested at the NASA Lewis Research Center. The vibration and efficiency test results will be used to enhance the data base for similar-class helicopters. Most of the data were obtained for a matrix of test conditions of 50 to 100 percent of rated rotor speed and 20 to 100 percent of rated input power. The transmission's mechanical efficiency at 100 percent of rated power was 97.3 and 97.5 percent with its inlet oil maintained at 355 and 372 K (180 and 210 F), respectively. The highest vibration reading was 72 g's rms at the upper housing side wall. Other vibration levels measured near the gear meshes are reported

Why Do Leaders Matter? The Role of Expert Knowledge
Why do some leaders succeed while others fail? This question is important, but its complexity makes it hard to study systematically. We draw on a setting where there are well-defined objectives, small teams of workers, and exact measures of leadersâ characteristics and organizational performance. We show that a strong predictor of a leaderâs success in year T is that personâs own level of attainment, in the underlying activity, in approximately year T-20. Our data come from 15,000 professional basketball games and reveal that former star players make the best coaches. This âexpert knowledgeâ effect is large

Why Do Leaders Matter? The Role of Expert Knowledge

We examine an industry in which there are well-defined objectives, small teams, and exact measures of leadersâ characteristics. We show that a strong predictor of a leaderâs success in year T is that personâs own level of attainment, in the underlying activity, in approximately year T-20. Our data come from 15,000 professional basketball games. The effect on team performance of the coachâs âexpert knowledgeâ is large and is discernible in the data within 12 months of his being hired.organizational performance, firms, leadership, fixed-effects, productivity
Non-collinear Korringa-Kohn-Rostoker Green function method: Application to 3d nanostructures on Ni(001)
Magnetic nanostructures on non-magnetic or magnetic substrates have attracted
strong attention due to the development of new experimental methods with atomic
resolution. Motivated by this progress we have extended the full-potential
Korringa-Kohn-Rostoker (KKR) Green function method to treat non-collinear
magnetic nanostructures on surfaces. We focus on magnetic 3d impurity
nanoclusters, sitting as adatoms on or in the first surface layer on Ni(001),
and investigate the size and orientation of the local moments and moreover the
stabilization of non-collinear magnetic solutions. While clusters of Fe, Co, Ni
atoms are magnetically collinear, non-collinear magnetic coupling is expected
for Cr and Mn clusters on surfaces of elemental ferromagnets. The origin of
frustration is the competition of the antiferromagnetic exchange coupling among
the Cr or Mn atoms with the antiferromagnetic (for Cr) or ferromagnetic (for
Mn) exchange coupling between the impurities and the substrate. We find that Cr
and Mn first-neighbouring dimers and a Mn trimer on Ni(001) show non-collinear
behavior nearly degenerate with the most stable collinear configuration.
Increasing the distance between the dimer atoms leads to a collinear behavior,
similar to the one of the single impurities. Finally, we compare some of the
non-collinear {\it ab-initio} results to those obtained within a classical
Heisenberg model, where the exchange constants are fitted to total energies of
the collinear states; the agreement is surprisingly good.Comment: 11 page
