In the course of live specially planned expeditions, the author studied the behaviour of man in the very special environment of caves. He explains the tests employed. The results obtained suggest that the human organism seems able to adapt to this uncommon environment but exhibits lethargy and reduced activity.
An Analytical Study Of Air Circulation In Caves, Arrigo A. Cigna
An Analytical Study Of Air Circulation In Caves, Arrigo A. Cigna
International Journal of Speleology
The different types of air circulation in caves are classified according to the origin of the circulation, as either static or dynamic. In a cave static causes are: (a) differences between inside and outside air density owing to: (i) air temperature; (ii) relative humidity; (iii) chemical composition; (b) atmospheric pressure variation. Dynamic causes are: (a) moving fluids: (i) inside the cave; (ii) outside the cave. Whenever possible the above mentioned phenomena have been considered from a mathematical point of view in order to obtain equations relating the different quantities involved.

Sur Quelques Collemboles Cavernicoles De Roumanie, Magdalena Gruia
International Journal of Speleology
An important collection of Collembola from Romania contained six species. One of them is new - Onychiurus orghidani n.sp. found in one cave of Oltenia. The presence of Onychiurus boldorii Denis in Romania is reported for the first time, and the discovery of a large number of Beckerella spelaea Ionesco made it possible to place this species in the genus Xenylla. Finally, additions are made to the known geographic distributions of Mesachorutes ojcoviensis Stach and Lepidocyrtus serbicus Denis.

Ökologie, Systematik Und Verbreitung Zweier In Norddeutschland Sympatrisch Lebender Bathynella-Arten (Crustacea, Syncarida), Siegfried Husmann
International Journal of Speleology
The sympatric occurrence of two bathynellids previously considered races of Bathynella natans - natans and stammeri - is evaluated as a natural ecological-genetic experiment. Since no hybrids appear in mixed populations, these forms are proven to be full species: Bathynella natans Vejdovsky and Bathynella stammeri (Jakobi). Besides the form of the mandibles, which until now was the only taxonomically useful diagnostic character in the genus Bathynella, 7 additional, suitably applicable morphological characters have been found (Table 3). The Bathynella biotope investigated is assigned to the “eustygopsammal” subterranean life province (Husmann 1966), which is associated with the “Parastenocaris-Bathynella” …

Ground Water Flow Systems Of Central Nevada, G. William Fiero Jr
Ground Water Flow Systems Of Central Nevada, G. William Fiero Jr
UNLV Theses, Dissertations, Professional Papers, and Capstones
The U.S. Atomic Energy Commission has been evaluating a large area of central Nevada in order to define a supplemental test site for the underground testing of high-yield nuclear devices. Safety considerations involving the radiocontamination of the ground water in the vicinity of the test site necessitated that research be conducted to determine the direction and rate of flow of the ground water. This investigation defines the ground water flow systems in eighteen valleys comprising 12,000 square miles of central Nevada.
The definition of the systems was made following a compilation of existing hydrologic and geologic data for the area. …

Strong-Coupled Piezoelectric Polaron, Wayne E. Tefft
Strong-Coupled Piezoelectric Polaron, Wayne E. Tefft
Physics Faculty Research & Creative Works
A semiclassical, variational calculation for the strong-coupled piezoelectric polaron gives the following results for the ground-state energy and polaron radius, respectively: U0=-0.47(m*/m) (κ2/ε)2eV, and R=3.5(ε/κ2) (m/m*)â ã where m* is the band effective mass, κ is the electromechanical coupling constant, and ε is the strain-free dielectric constant. The theory is expected to be valid when |U0| is larger than thermal energies and R is considerably larger than unit-cell dimensions. A calculation of the polaron effective mass, having a more limited region of validity, gives mp~m*[1+2|U0|/m*vs2], where vs is the velocity of sound. …

Water Quality Study Of Lake Mead, Dale A. Hoffman, Paul R. Tramutt, Frank C. Heller, Bureau Of Reclamation
Publications (WR)
This report presents Lake Mead Water quality data obtained from 1964 to 1966. The effect of filling Lake Powell on the water quality of Lake Mead is evaluated. General limnological principles and the present limnology of Lake Mead are discussed. Lake Mead has a warm monomictic annual temperature cycle characterized by summer stratification, fall overturn leading into a continuous circulation throughout the winter; temperatures never fall below 39 deg F (4 deg C). During stratification, lower dissolved oxygen values were recorded in the thermocline than in the epilimnion and hypolimnion. Mineral content increases from the upper to the lower end …
Survival Probability In Dissociative Attachment, Joseph C.Y. Chen, Jerry Peacher
Survival Probability In Dissociative Attachment, Joseph C.Y. Chen, Jerry Peacher
Physics Faculty Research & Creative Works
The survival probability in dissociative attachment is investigated with special attention to the (e, H2 ) system. It is shown that the simple expression for the dissociative-attachment cross section, as given by the product of a capture cross section and a survival probability, is equivalent to the s -wave approximation for the g → g dissociative attachment. This expression, however, does not constitute an approximation for the g → u dissociative attachment, since the parity of the initial rotational states of H2 is always opposite to that of the relative angular momentum states of H and H- …
A Study Of The Synthesis And Reactions Of Condensed Pyriadazines, Lorraine Marie Distefano
A Study Of The Synthesis And Reactions Of Condensed Pyriadazines, Lorraine Marie Distefano
Chemistry and Chemical Biology ETDs
A special interest in a nitramine rearrangement prompted the preparation of 1,4-diaminopyridazino [4,5-d] pyridazine and the nitration of this compound. Several reactions of the intermediates, which were synthesized en route to 1,4-diaminopyridazino [4,5-d] pyridazine, were studied. Strong evidence for the existence of keto-enol tautomerism was found in the case of 1,4-dihydroxypyridazino [4,5-d] pyridazine and its derivatives.
Some reactions of 5, 8-dichloropyrazino [2,3-d] pyridazine were studied with particular interest in the nucleophilic displacement of azides and in the nitration of 5,8-dianilinopyrazino [2,3-d] pyridazine.
The nitration of diaminophthalazine was also attempted in order to perform an acid catalyzed nitramine rearrangement from one …
Criteria For The Determination Of Flow Direction In Volcanic Rocks, Eugene Irwin Smith
Criteria For The Determination Of Flow Direction In Volcanic Rocks, Eugene Irwin Smith
Earth and Planetary Sciences ETDs
A statistical method employing the Tukey Chi-square test and the vector method was used for determining the direction of primary flow lineation in volcanic rocks. Oriented samples were collected from the McCartys Basalt, the porphyritic andesite of Mount Taylor and the Bandelier and Battleship Rock Rhyolite Tuffs of the Jemez Mountains. All these localities are in New Mexico. Measurements were taken of the elongate particles in each horizontal thin section. The flow lineation direction in each slide was determined statistically by computing values of vector mean or chi-square orientation. The McCartys flow samples showed the lowest reliability. This was probably …

The purposes of the study were: (I) to find out if there is any difference in the practices of Adventist and non-Adventist teenagers, and (2) to determine their attitudes toward snacking and omission of breakfast.
Results of the questionnaire were coded, punched onto IBM cards, and fed into computing machines for item and statistical analysis. Chi-square test analyses were done on denominational classification against some questions of interest to show any significant differences between Adventist and non-Adventist students' responses. …
Very High Pressure Effects Upon The Epr Spectrum Of Ruby, H. Mark Nelson, D. B. Larson, J. H. Gardner
Very High Pressure Effects Upon The Epr Spectrum Of Ruby, H. Mark Nelson, D. B. Larson, J. H. Gardner
Faculty Publications
The variation in the electron paramagnetic resonance (EPR) spectrum of ruby as a function of pressure has been observed to beyond 70 kbar for a magnetic field orientation parallel to the crystalline c axis. The data can be interpreted in terms of the usual spin Hamiltonian, where the spectroscopic splitting factor g|| has the same value as at ambient pressures, but where the zero-field splitting deltaincreases in a linear fashion from 0.38 to 0.43 cm. The experimental apparatus has been described previously, although important improvements in the pressure seal and in the pressure calibration have been made and are described …
On Some Categories Of Partially Ordered Sets With Residuated Mappings, Gary D. Crown
On Some Categories Of Partially Ordered Sets With Residuated Mappings, Gary D. Crown
Mathematics & Statistics ETDs
Croisot [1] was apparently first to examine some of the properties of residuated mappings. It is the purpose of this paper to show that certain constructions currently useful in homological algebra can be made in a suitable category of partially ordered sets with residuated mappings. In Section 1 we note some elementary properties of residuated mappings all of which are well known cf. Janowitz [4]. In Section 2 we notice some properties of various categories of partially ordered sets with residuated mappings. In Section 3 we prove that the category of complete lattices with residuated mappings has enough injectives and …
The Kinetics Of Phase Transitions In Solid Cyclohexanol And Related Plastic Crystals., William Thomas Griffith
The Kinetics Of Phase Transitions In Solid Cyclohexanol And Related Plastic Crystals., William Thomas Griffith
Physics & Astronomy ETDs
The phase relations and the kinetics of phase transitions in the solid -forms of cyclohexanol, cyclohexanone, chlorocyclohexane, bromocyclohexane, and cyclopentanol have been investigated. Cyclohexanol has been studied the most thoroughly; the other compounds have been considered largely for purposes of comparison with cyclohexanol. The primary methods of investigation have been the measurement of dielectric properties and visual observations. The transitions in cyclohexanol have also been followed photographically in order to measure the growth velocities of the phase interfaces.
Room-Temperature Second-Order Raman Spectra Of Csc1, Csbr, And Csi, A. M. Karo, John R. Hardy
Room-Temperature Second-Order Raman Spectra Of Csc1, Csbr, And Csi, A. M. Karo, John R. Hardy
John R. Hardy Papers
The room-temperature Raman spectra of CsC1, CsBr, and CsI have been computed from a simple, combined density-of-states approximation. Calculations have been made for four different model potential functions and compared with experiment in the cases of CsBr and CsI. In this way it is found that one of the variations, called the DD(-) model, is the most satisfactory. The agreement with the observed spectra is surprisingly close when one considers that no allowance has been made for variations in the elements of the Raman polarizability tensor.
The Ion-Exchange Chromatographic Separation Of The Components Of The Product Mixture Resulting From Reaction Of Trans-Dichlorobis (Ethylenediamine) Cobalt (Iii) Chloride With Thiocyanate Ion, William Trew Jordan
Dissertations and Theses
The object of the research was to study, by means of ion-exchange chromatography, the product mixture resulting from reaction of trans-[Co(en)2Cl2]Cl and SCN-. Cis-and trans-[Co(en)2(NCS)Cl]Cl had previously been obtained as products of this reaction. However, the possibility of the presence of other products consistent with the nature of the reactants could not be dismissed. These include the dichlora, dithiocyanato, and aqua complexes.
The constituents of the solution resulting from the reaction were separated on a column of Dowex 50W-X8 resin by elution with hydrochloric acid. The eluted fractions were evaporated at room …

Nurse-Patient Interpretations Of The Nurse's Touch, Judith Ann Trowbridge
Nurse-Patient Interpretations Of The Nurse's Touch, Judith Ann Trowbridge
Loma Linda University Electronic Theses, Dissertations & Projects
The purpose of this study was to discover whether or not patients and nurses derived a similar meaning from pictures of a nurse touching a patient in various ways. Five by seven inch black and white photographs were shown to thirty patients and thirty registered nurses. The subjects were controlled in regard to sex, race, residence, language, and physical and emotional orientation. They were asked to focus upon the photographed nurse's touch and to tell in one or two words what meaning they felt that the nurse was trying to convey to the patient by her touch. Responses were recorded …
The Effects Of Particular Sounds On Certain Indices Of Cardio-Pulmonary Functions, Harold F. Googe, Jane Mundin
The Effects Of Particular Sounds On Certain Indices Of Cardio-Pulmonary Functions, Harold F. Googe, Jane Mundin
Loma Linda University Electronic Theses, Dissertations & Projects
The purpose of this study was to identify the effects of particular sounds upon certain indices of cardio-pulmonary function and the degree and pattern of changes which occurred in the indices. The specific physiological parameters chosen to be monitored were heart rate, respiratory rate, mean tidal volume, instantaneous minute volume, and oxygen consumption. The hypothesis was that particular sounds will cause changes in certain indices of cardio-pulmonary functions. This was a controlled experiment, in which nine healthy males and nine healthy females, of a denominational, medically oriented University listened to a specially constructed tape of background music interspersed with an …

Radiolysis Of The Extract From The Sawdust Of The Ponderosa Pine, Mervin B. York
Loma Linda University Electronic Theses, Dissertations & Projects
Portions of an acetone-hexane (1:4) extract of Ponderosa pine sawdust were exposed to gamma and ultraviolet radiation. The three solutions, including the original, were checked for antibiotic activity on: Staphylococcus aureus Escherichia coli and Bacillus cereus. Results indicated that each solution inhibited the growth of the bacteria.
The three solutions were separated into fractions by 'column' chromatography on silica gel, using chloroform-carbon tetrachloride (1:1) as the elutant and then 10-20-50-80% ethanol in the chloroform- carbon tetrachloride mixture and finally 100% ethanol. Ten fractions were obtained from each sample and these were each tested on the bacteria. Results indicated a number …
Secondary Reactions And Partial Rate Factors In The Sulfonation Of Chlorobenzene And Toluene, Ernest Arthur Brown
Secondary Reactions And Partial Rate Factors In The Sulfonation Of Chlorobenzene And Toluene, Ernest Arthur Brown
Theses and Dissertations
The sulfonation of chlorobenzene, chlorobenzene-benzene, and toluene-benzene mixtures by sulfur trioxide in liquid sulfur dioxide at -12.5° C. was studied to obtain isomer distribution and relative rate data. The isomer distribution for the reaction on chlorobenzene was determined by an isotope dillution technique. Relative rate experiments were conducted by sulfonating C14 labeled benzene in competition with nonradioactive chlorobenzene and toluene and the count rate of the products was used to determine product composition. Ultraviolet spectrophotometry was also used to investigate variations in isomer distributions as a function of sulfur trioxide concentration. The apparent relative rates of sulfonation (kX/kB) as calculated …
A Study Of The Backscatter Of Light From A Single Water Droplet, Theodore Stauffer Fahlen
A Study Of The Backscatter Of Light From A Single Water Droplet, Theodore Stauffer Fahlen
Physics & Astronomy ETDs
The backscattered light from a single water drop is studied theoretically and experimentally for drop diameters of about one millimeter. G. Mie gave the exact mathematical solution to the problem of an infinite, plane, monochromatic, electromagnetic wave scattered from a perfect sphere of any radius and index of refraction in 1908. The results of this theory are applied to drops of size parameter (defined as the ratio of the drop circumference to the wavelength of the incident light) near 3000; this corresponds to a drop diameter of about one millimeter. Theoretically, it is shown that the backscattered light originates from …
Evaluation Of The Dispersion Relations Of Photoproduction, Paul Finkler
Evaluation Of The Dispersion Relations Of Photoproduction, Paul Finkler
Paul Finkler Papers
A modification of the Omnes method is used to solve the singular integral equations for the 3-3 partialwave amplitudes of photoproduction. The effects of multipion production are assumed to be negligible. The method requires a knowledge of the phase at all energies. Consequently, it is necessary to treat the corresponding pion-nucleon scattering problem to determine the eBect of the high-energy behavior of the phase on the solution for the scattering amplitude at low energies. The sharply resonant nature of the problen suggests an approximation in the form of solution, rather than in the Born terms, which leads to relatively simple …
