Second- And Third-Order Elastic Constants Of Aluminum And Lead, Tetsuro Suzuki

Physics Faculty Research & Creative Works

The second- and third-order elastic constants of Al and Pb are calculated as the second and third derivatives of the binding energy with respect to the finite deformation parameter. The binding energy is derived from a local pseudopotential by use of second-order perturbation theory. It is shown that the binding energy satisfied not only the diagonal equilibrium condition, but also the off-diagonal equilibrium condition, i.e., the first derivative of the binding energy with respect to a volume change as well as with respect to shear deformations is zero. Accordingly, the present method of calculation is based on a stable lattice …

Deux Monolistrini Nouveaux (Crustacea, Isopoda) Des Eaux Souterraines De Croatie, Christa L. Deeleman-Reinhold

International Journal of Speleology

A new subspecies and a new species are described: Monolistra (Monolistra) caeca meridionalis nov. subspec. was found in three caves in the northern part of Croatia, Yougoslavia. It is distinguishable from the typical form principally by the thin, acuminate form of the protuberance of the protopodite of the 2nd male peraeopod, by the endopodite of the 1st pleopod which bears 3-4 setae (1-2 in M. c. caeca), by the somewhat wider endopodite of the 3rd pleopod and by the shorter, only slightly curved uropods. A sketch shows the situation of 6 newly discovered localities in northern Croatia, 3 of …

Note On Lepidoptera From Bulgarian Caves, Andrzej Skalski

International Journal of Speleology

This paper is a report on Lepidoptera collected in 1960 in some caves of the Stara Planina Mountains (Bulgaria). In three caves in the environs of Lakatnik the following species were found: Acrolepia granitella Tr., Acrolepia pulicariae Klim., Autophila limbata Stgr., and Triphosa sabaudiata Dup. Two species (Acrolepia pulicariae Klim. and Autophila limbtia Stgr.) are new for both the cave fauna of Bulgaria and fauna of Bulgaria.

The Subterranean Fauna Associated With The Blind Palaemonid Prawn Typhlocaris Galilea Calman, Moshe Tsurnamal, Francis Dov Por

International Journal of Speleology

Exploration of the subterranean tract of the spring of En-Nur (at the North end of Lake Tiberias) by scuba diving and by use of new collecting methods, led to the discovery of a living community associated with the blind prawn Typhlocaris galilea. A rich growth of sulphur bacteria and of pigmentless Cyanophyceae from the trophic basis in this peculiar biotope. Representatives of three hypogeic crustacean orders have been found as well as some peculiar gastropods, nematods and oligocaets. The latter are the main food of Typhlocaris galilea.

A New Cave Amphipod Crustacea From Japan, Masuzo Uéno

International Journal of Speleology

A new eyeless Amphipod Crustacea 5 mm long was found in Himisé-dò Cave in Tokushima Prefecture, Shikoku. The inner ramus of its third uropod is nearly as long as the unijointed outer ramus. The accessory flagellum of the first antenna consists only of a single joint. The first maxilla is distinctive in its small palp which does not extend beyond the apical margin of the outer plate and bears only an apical seta. In these characteristic features the present form is different from any known species of the genera of the Crangonyx and Hadzia groups and seems to belong to …

Quaire Nouvelles Bathynella (Crustacea, Syncarida) De Roumanie: De Nouveau Sur Le «Dilemme Bathynella Natans Vejd», Eugène Serban

International Journal of Speleology

The paper presents the diagnosis of 4 new Bathynella species found in Romania: B. paranatans nov. sp., B. boteai nov. sp., B. motrensis nov. sp. and B. plesai nov. sp.; a discussion on B. cf. scythica Botosàneanu et Damian is also given. The morphological features which were used are the general and the fine structure of the genital pereiopode of the male (Pl. 5—8), the chaetotaxy of the maxillula, maxilla, thoracic appendages, uropods and furca. The presence of the distal (coxal) epipodite on the first pereiopod in B. paranatans nov. sp., distinguishes this species from the others (Pl. 1—4). The …

Food And Feeding Habits Of The Troglobitic Carabid Beetle Rhadine Subterranea, Robert W. Mitchell

International Journal of Speleology

Food and feeding habits of a population of the troglobitic carabid beetle Rhadine subterranea inhabiting Beck’s Ranch Cave, Williamson Co., Texas, were investigated. Observational and experimental data demonstrate that a primary food source of this beetle is the eggs of cave crickets (Ceuthophilus spp.). The beetles locate eggs by selective digging into substrata where cave crickets have oviposited. Chemoreception and mechanoreception are important in the location of oviposition sites.

Preference Responses And Tolerances Of The Troglobitic Carabid Beetle, Rhadine Subterranea, Robert W. Mitchell

International Journal of Speleology

Studies were made on the preference responses and tolerances of the troglobitic carabid beetle Rhadine subterranea to light, temperature, and relative humidity. The beetles are weakly photonegative and appear to have a strong preference for atmospheres of low saturation deficit. Both these responses seem to be orthokineses. They have a strongly developed temperature sense, and their temperature preferendum shifts seasonally. This response seems to be a klinotaxis. They are neither strongly stenothermal nor stenohygrobic. The preference responses, especially that of temperature, are probably mechanisms tending to restrict the beetles to their habitat. The tolerance data suggest that the epigeum could, …

A New Species Of The Subterranean Amphipod Genus Allocrangonyx (Gammaridae), With A Redescription Of The Genus And Remarks On Its Zoogeography, John R. Holsinger

International Journal of Speleology

The systematics of the North American, subterranean amphipod genus Allocrangonyx are revised and two species are recognized - A. pellucidus (Mackin) and A. hubrichti, new species. Allocrangonyx is critically compared with the European genus Niphargus and several endemic North American genera of the Crangonyx group. Because of its unique morphological position, Allocrangonyx is removed from the Crangonyx group and placed in the newly designated AlIocrangonyx group. Some factors believed to have influenced speciation within the genus are discussed in some detail.

Durées De La Mue, De L'Intermue Des Adultes, Et Longévité De Stenasellus Virei Dollfus (Crustacé Asellote Troglobie), Guy Magniez

International Journal of Speleology

The author’s observations of numerous cases of molting in the hypogean asellid Stenasellus virei Dollfus, 1897 appear to show that the phenomenon occurs in two steps. The loss of the anterior exuvium is separated from that of the posterior exuvium by a period of 8 to 16 days in adults from cavernicolous populations of Stenasellus virei in the Pyrenees and Cantabrian Alps. The intermolts last from 9 to 18 months for the same individuals. One must allow, for this species, a minimun life span of 10 years. Values of the same order of magnitude are anticipated for the two other …

Contribution À L'Étude Des Mycetophilidae Des Grottes De Roumanie Avec La Description De Deux Espèces Nouvelles, Anca Burghele-Balacesco

International Journal of Speleology

The study of Mycetophilidae collected in Romanian caves during these past years enables us to add 24 species to those already known from the country, among which two are new for science: Exechia dumitrescui n. sp. and Rhymosia matilei n. sp. Sixteen species belonging to the genus Macrocera, Zelmira, Leia, Exechia, Rhymosia, Allodia, Mycetophila, Zygomyia and Deolpsis have never been mentioned before for the subterranean environment. Some of these species are extremely rare: Exechia januari Lundst., E. parallela Edw., Rhymosia tarnani Dzeid., Phronia kowarzi Dzicd., Mycetophila rudis Winn.

Les Milieux De Vie De Stenasellus Virei Dollfuss, 1897 (Crustacé Asellote Troglobie): Données Préliminaires, Guy Magniez

International Journal of Speleology

Stenasellus virei is now known from 77 localities (caves, phreatic waters and underflow of some rivers) of the eastern Aquitanian basin, central and eastern Pyrenees, and of Spain. A classification of the different biotopes of the species is attempted herein, and some of their characteristics are summarily described. This cavernicolous species can now be viewed in a new light, as much ecological as systematic or biogeographic.

Trichoniscoides Saeroeensis Lohmander, An Isopod Crustacean New To The British Fauna, Edith M. Sheppard

International Journal of Speleology

The terrestial isopod Trichoniscoides saeroeensis Lohmander, new to the British fauna, is recorded fram the dark zone of disused mines in Lancashire; the paper includes notes on its systematic position and certain morphological characters as well as its affinities. The origin and geographical distribution of the species, together with that of the other two species recorded in England [T. albidus (Budde-Lund) and T. sarsi Patience], is discussed.

High-Pressure Phase Studies On Sodium–Potassium Alloys, D. Ray Anderson, J. Bevan Ott, Rex J. Goates, H. Tracy Hall

Faculty Publications

The solid–liquid phase diagrams were investigated to 60 kbar for elemental sodium, potassium, and various sodium–potassium alloys. The data for Na and K are in general agreement with those of earlier workers. In the alloy system the temperatures of both the peritectic and eutectic halts increase as the pressure increases, but with different slopes, so that the two invariant points merge at approximately 35 kbar. Above this pressure, two halts are again observed. One increases with increasing pressure, and the other decreases with increasing pressure up to 55 kbar, where it abruptly starts increasing again. Melting points for samples in …

Distribution And Dispersion Of The Troglobitic Carabid Beetle Rhadine Subterranea, Robert W. Mitchell

International Journal of Speleology

Intracave distribution and dispersion patterns within a population of the troglobitic carabid beetle Rhadine subterranea were studied. Distribution was markedly heterogeneous, the beetles being almost entirely restricted to substrata of deep, uncompacted silt. Dispersion of the beetles on the silt substrata did not depart from random expectation. It is shown, however, that this is a functionally emergent pattern resulting from an intrasex repulsion related to feeding which tends to produce regularity counterbalanced by an intersex attraction related to reproduction which tends to produce contagion.

Stenasellus Skopljensis Thermalis Ssp.N. (Crustacea, Isopoda) D'Une Source Chaude En Bosnie, Milan Meštrov, Romana Lattinger-Penko University Of Zagreb

International Journal of Speleology

The new subspecies Stenasellus skopljensis thermalis, from Banja Luka (Bosnie, Yugoslavia) is described. From the ecological point of view this form differs from the others because it inhabits underground waters of elevated temperature (240°C). Another constantly abundant species, St. hungaricus thermalis Mestrov, also occurs in Yugoslavia under the same ecological conditions, in the warm springs of Podsused near Zagreb. This indicates that these underground waters at elevated temperature are not accidental but preferred habitats for these forms, and confirms once again that thermal waters of this type are the biotopes-refuges in which certain relic forms are retained.

Integrability Of The Sums Of The Trigonometric Series 1/2 Aₒ + ∞ [Over] Σ [Over] N=1 AN Cos Nθ And ∞ [Over] Σ [Over] N=1 AN Sin Nθ, John William Garrett

"The trigonometric series C = 1/2 aₒ + ∞ [over] Σ [over] [n=1] a[subscript n] cos nΘ and S = ∞ [over] Σ [over] n=1 a[subscript n] sin nΘ, where {a[subscript n]} monotonically decreases to zero both converge almost everywhere to functions f and g respectively. f (or g) is L iff C (or S) is the Fourier series of f (or g) iff term-by-term integration of C (or S) is valid. There are three equivalent conditions, each of which implies that C is the Fourier series of f...."--Abstract, page ii.

Hydrothermal Alteration Of Ash-Flow Tuffs In The Indian Peak District Of Southwestern Utah, Michael Allan Tolley

Masters Theses

"Careful petrographic study of the ash-flow tuffs in the Indian Peak District of southwestern Utah reveals hydrothermal alteration around the fluorite veins. The alteration minerals themselves and the intensity of alteration vary with distance from the veins. Primary plagioclase has altered to secondary feldspar, calcite, sericite, and traces of epidote and zoisite. Hornblende and biotite have altered to chlorite, calcite, and secondary iron oxide, and traces of epidote and zoisite. Diopside has changed to calcite and secondary iron oxide. An overall picture of the mining district shows that certain minerals increase and others decrease as one nears the veins. Hydrothermal …

Fossil Otoliths Of Some Lower Cenozoic Perciform Fishes Of The Gulf Coast, Mostafa Juma Salem

Masters Theses

"Nineteen perciform species from the lower Cenozoic and one Recent species are described, and included under eight genera. The main characters that were considered as generic are the outline of the sagitta and the structure of the sulcus. The other features of the otolith were regarded as secondary in importance. The characters that were believed to be valuable at specific level are almost the same as those for the genus but in more detail. These species are considered to be within the Suborder Percoidei. The fossil species of "Nemipterus" were put in the Family Nemipteridae as they resembled the Recent …

Geology, Geochemistry And Lava Tubes In Quaternary Basalts, Northeastern Part Of Zuni Lava Field, Valencia County, New Mexico, James Douglas Causey

Earth and Planetary Sciences ETDs

Basaltic volcanism in the northeastern part of the Zuni lava field is related to a north-northeast trending regional fracture system. This is shown by elongation of centers and their alignment. However, .the fractures do not control the direction of lava tubes.

There are three distinct stages of volcanic activity common to the Zuni lava field:

1) early pyroclastic eruptions,

2) quiescent flows or fissure eruptions􀀅

3) late pyroclastic eruptions.

Evidence for the first stage is sometimes lacking, but the second and third stages can always be seen.

The basalts range from weakly tholeiitic to alkali in nature. Potassium content varies …

I. Existence Of Eigenvalues For Integral Equations; Ii. A Collocation Method For Boundary Value Problems, Robert Dodd Russell

Mathematics & Statistics ETDs

I. The existence of eigenvalues is shown for certain classes of integral equations with continuous kernels. A number of interesting and useful results are thereby treated in a unified and relatively elementary way. The simplicity of these new proofs make the results accessible to introductory courses on the theory of integral equations.

II. Collocation with piecewise polynomial functions is developed as a method for solving two-point bour:rlary value problems. Convergence is shown for a general class of linear problems and a rather broad class of nonlinear problems. Some computational examples are presented to illustrate the wide applicability and efficiency of …

Some Results On The Distance Properties Of Convolutional Codes, Luther D. Rudolph, Alexander Miczo

Electrical Engineering and Computer Science - Technical Reports

Rate 1/2 binary convolutional codes are analyzed and a lower bound on free distance in terms of the minimum distances of two associated cyclic codes ìs derived. Next, the complexity of computing the free distance is discussed and a counterexample to a conjecture on the relationship of row distance to free distance for systematic codes Ìs presented. Finally, an improved Gilbert bound for definite decoding is derived.

Doppler Shift In Frequency In The Transport Of Electromagnetic Waves Through An Underdense Plasma, Jerry Peacher, Kenneth M. Watson

Physics Faculty Research & Creative Works

In an earlier publication, the validity of the radiation transport theory was studied for the calculation of multiple scattering of electromagnetic waves by a turbulent plasma. In the present paper, we extend the transport theory to include a description of the Doppler shift in frequency caused by electron motion.

Ornitrol: Recent Developments, M. R. Woulfe

Bird Control Seminars Proceedings

This talk today will be on recent developments with Ornitrol. All the recent developments have been with blackbirds and grackles; and, unfortunately, the man who has done the most recent work is sitting right here, so I can't steal his data very well!

We have done some work since I spoke to you last on some of the pharmacol¬ogy of SC-12937--which is an axocholesterol the active ingredient of Ornitrol. One of these developments is the determination of the half-life of SC-12937, which is 28 days. This is the reason, we feel, for its prolonged activity in birds. It is stored …

Trapping Feral Pigeons, J. O. Bull

Bird Control Seminars Proceedings

When I look at the multitude of pests and diseases you have here in the United States, it is a miracle to me that you are still alive today. The United King¬dom is fortunate in having very few bird pests in urban areas. We have the English Sparrow, the starling, and the feral pigeon. We are also a nation of bird lovers, with a large number of organizations that look after the welfare of wild birds. So, we in pest control have to be very careful in our control procedures.

Now let me move along to our feral pigeon trapping …

Registration Patterns For Avicides, James O. Lee

Bird Control Seminars Proceedings

Federal legislation relating to pesticide use in the United States dates back to 1910 with passage of the Federal Insecticide Act. This consumer protection from sub¬standard or fraudulent products was considered sufficient for the next 37 years.

In 1947, Congress passed the Federal Insecticide, Fungicide, and Rodenticide Act. The FIFRA superseded the earlier legislation and was designed as a regulatory measure. Under the Act any product considered an "economic poison" must be reg¬istered with the U.S. Department of Agriculture before it may be marketed in inter¬state commerce.

The FIFRA defines an economic poison as any substance or mixture of sub¬stances …

Investigation Of The Alpha-Sub-Gamma Phase In Alnico 6, Cortez Samuel

Dissertations and Theses

The purpose of this research project was to study the αᵧ phase in Alnico 6. Other phases were studies for comparison. Also the effect of an applied magnetic field on the formation of the αᵧ phase was investigated.

Three single crystals of Alnico 6 were heat treated for one hour--one at 1250°C, one at 1000°C, and one at 800°C--and water-quenched. The microstructure of each sample was observed with the optical microscope, and X-ray diffraction patterns were taken to determine the crystal structure of the phases present.

Several single crystal samples of Alnico 6 were heat treated at 1000°C and furnace-cooled. …
