The Origin Of The Bedded Arkansas Barite Deposits (With Special Reference To The Genetic Value Of Sedimentary Features In The Ore), Richard A. Zimmermann

Doctoral Dissertations

"The objective of this study has been to determine the geometric and mineralogic relationships existing between the barite and related sediments in the Stanley Shale in Arkansas and also to establish geometric, mineralogic, petrographic, and geochemical criteria for the interpretation of the origin of the barite and associated minerals. In addition, comparisons with German deposits have been made"--Introduction, Objective and Outline of Study, page [1].

On The Kirkwood Superposition Approximation, Russell V. Cochran Jr.

Doctoral Dissertations

"When the Kirkwood superposition approximation for the triplet distribution function is used in the Born-Green equation for the pair distribution function of a liquid, the fourth virial coefficient is given incorrectly. In view of this, two suggestions for improving the approximation have been investigated. A suggestion, due to G.H.A. Cole, that better results could be obtained by using a second-order integro-differential equation of the Born-Green type with the superposition approximation used for both the triplet and quadruplet distribution functions has been investigated, and results for a hard-sphere model show that this method gives considerably less reliable results than those obtained …

A Parameter Perturbation Procedure For Obtaining A Solution To Systems Of Nonlinear Equations., James Carlton Helm

Masters Theses

"For simultaneous nonlinear equations the convergence of the known functional iterative procedures is dependent upon a good initial approximation to the desired roots. In this paper the restriction on the choice of the initial approximation has been circumvented by dividing each problem into a number of subsidiary problems in accordance with a parameter perturbation procedure. The study presents a discussion of the algorithm and the conditions for convergence. The discussion, also, includes the problems which were solved using the parameter perturbation procedure"--Abstract, p. ii

Petrology And Mineralogy Of Certain Portions Of The Fredericktown Deposits, Farouk El Baz

Doctoral Dissertations

"The Fredericktown area is part of the 'Lead Belt' district of southeastern Missouri, the major lead-producing region in the world for fifty years. The district is a typical example of the Mississippi Valley Type deposits. The ores occur in Upper Cambrian sediments overlying Precambrian rocks.

The Fe-Cu-Pb-Zn (-Co-Ni) - sulphide deposits of Fredericktown occur over a few square kilometers in sediments overlying two 'granite knobs'. The sedimentary units lap upon and pinch-out against these buried basement hills.

The basal sedimentary unit, the Lamotte Formation, is a time-transgressive, marine, submature orthoquartzite. It contains a Boulder Bed at the base or at …

The Protein Of Phleum Pratense, Clifford A. Dean

University of the Pacific Theses and Dissertations

As the chemist increases his knowledge and understanding of the complex and delicate nature of the proteins, many of the methods which are used in the handling and treatment of protein systems need to be reviewed and reexamined in the light of the new information which is now available.

This study has endeavored to take the biologically active protein system from the pollen or timothy grass (Phleum pratense) and examine its stability under currently used methods of extraction, purification, and storage.

New chemical agents were studied in connection with the above mentioned protein tor their possible use in the place …

A Study Of The Platinum (Ii), Palladium (Ii), And Rhodium (Iii) Chelates Of Aspartic And Glutamic Acid, Cecilia Elizabeth Luschak

University of the Pacific Theses and Dissertations

It is fairly well known that alpha-amino dicarboxylic acids combine quite readily with basic metal ions such as the alkaline earths. The nature of the problem includes the synthesis and characterization of six platinum metal chelates of two alpha-animo dicarboxylic acids, namely aspartic and glutamic acids. The metal ion upon which the investigation is focused are platinum (II), palladium (II), and rhodium (III). Several of these are reported as having been repaired. The series is incomplete, however, and little study has been done correlating the abilities and trends of the complexes as a function of the metal ion and carbon …

Chalcone Derivatives From Pyrrole-2-Aldehyde, Ahmad Hamidi

University of the Pacific Theses and Dissertations

Claisen first synthesized Chalcone in 1881 by condensing acetophenone with benzaldehyde using sodium methoxide as a condensing agent. Chalcone and its derivatives have been prepared primarily as intermediates for the synthesis of anthocyanins and other related pigments.

In recent years extensive preparation and study of chalcones has been carried out utilizing chalcones for their biological effects in medical and pharmaceutical fields. It has been shown that certain highly substituted compounds present in the flower pigments as additives to adhesive absorb ultraviolet radiation. Carboxylic acid chalcones have become known for their therapeutic action in the treatment of chronic kidney diseases, diseases …

Über Die Moose, Die Unter Dem Einfluβ Der Elektrischen Beleuchtung In Das Innere Der Höhlen In Ungarn Und In Der Tschechoslowakei Eindringen, A. Boros

International Journal of Speleology

The introduction of electrical illumination into different caves makes the intrusion of some mosses and ferns into such depths of the caves possible which at previous occasions (i. e. before the installation of electrical light) were found sterile of these plants. Investigations of two caves in Czechoslovakia and 4 caves in Hungary revealed the presence of mosses thriving deep inside of these caves making use of the artificial illumination.

Remarques Sur Les Japygidae (Insecta, Diplura) Signalés Dans Le Domaine Souterrain, Jean Pagés

International Journal of Speleology

About 50 japygids, belonging to 29 distinct forms of which 23 are recognizable, have been collected since 1874 in caves all over the world. A list is given, by continent and by countries. Ten species found both in the soil and in caves are called troglophiles to emphasize the sorting which seems to occur among endogenous species. Of the remaining 13 species, all considered troglobites, only 3 show morphological peculiarities which can be ascribed to adaptation to cavernicolous life: (1) Metajapyx moroderi ssp. patrizianus Pagés from Sardinia shows a slightly longer 10th urite and cerci than the f. typ.; (2) …

Observations Sur L'Évolution Des Grottes, Albert Cavaillé

International Journal of Speleology

In this note, which results from a paper published in France, the author defines the “karst system” formed by several successive levels, at the heart of a limestone mass: joints of surface feeding, vertical chimneys, galleries which are alternatively dry and full of water according to the season, a network of continually drowned clefts. He then studies modifications in this system resulting from internal causes, corrosion, filling and sedimentation, concretion. Then he shows how this evolution of the karst system may be modified by general conditions: geology, tectonics, geography with the losses, resurgences and the role of surface formations. The …

Remarques Sur La Signification Des Expériences En Géodynamique Karstique, Ph. Renault

International Journal of Speleology

Distinction is made between the experiment which “demonstrates” having an argumentative value - and the experiment which “questions” nature by isolating one factor and by determining the mode of its action. The concept of experiment in geology and in geodynamics and the distinctions between geodynamics and geophysics are discussed. Karstic geodynamics considers the action of fluids - mainly liquids - on a soluble rock. It is a science bordering the different branches of geochemistry, hydrology, the mechanics of rocks, and geophysics. Researches in karstic geodynamics are based upon measurements obtained through field surveys, or upon the utilization of a subterranean …

Essai Sur Une Étude Au Microscope Électronique De La Microflore Des Sédiments Argileux De Cavernes (A Preliminary Study Using An Electron Microscope, On The Microflora Of Cave Clay Sediments), V. Caumartin

International Journal of Speleology

Researches on the microflora of cave clay sediments were carried out. The study of these micro-organisms necessitates the use of an enlargement of the order of 5,000. For this purpose the organisms were separated from the clay sediments by the foam flotation technique, followed by cultivation. Morphologically they can be divided into 5 types but together they form a group sufficiently homogeneous to justify their provisional grouping as the “Microfusiformetum.” Experiments with enriched cultures from several sediments have shown that certain of the micro-organisms were indigenous, others were accidental inhabitants.

Corrosion Par Mélange Des Eaux, Alfred Bogli

International Journal of Speleology

Karst caves are prior to all due to corrosion. According to the well-known formula a CO₂ supply is always needed. This type of dissolution explains only the corrosion in free circulation and, under reserve, the one in pressure conducts in the vadose zone. All corrosion in the phreatic domain is excluded, except for some rare cases in the upper levels. The corrosion by mixing of waters of different content in bicarbonates is effective in the entire karst, from the lowermost to the uppermost parts. Also the corrosion due to the lowering of temperature and by mixing of waters at …

Detection Of Caves By Gravimetry, Raymundo J. Chico

International Journal of Speleology

For gravimetric investigations, a naturally occurring limestone cave may be compared with a buried empty sphere or cylinder, depending on its shape. The practical limit of detection for a subsurface void, utilizing available equipment (Worden gravity meter) and standard field procedure, is 0.1 milligal. Most corrections normally required by the gravimetric method may be neglected in cave detection, but the altitude control for the field traverse must have an accuracy of ± 0.1 foot. The detectability of a limestone cave, based on field work done at Luray Caverns, Virginia, and at other localities, is related to its shape, Radius (R), …

Naissance De La Biospéologie, Constantin Motas

International Journal of Speleology

Modern biospeleology dates from May 15, 1907, with the publication of Racovitza’s “Essai sur les problèmes biospéologiques.” In this paper he posed - if he did not answer - every question raised by life in the subterranean world. He outlined a program of biospeological research, made an analysis of the conditions of existence in the subterranean domain and their influence upon cavernicoles, discussed the evolution of subterranean biota, their geographical distribution, etc. Racovitza modified Schiner’s (1854) classification, dividing cavernicoles into troglobites, troglophiles and trogloxenes, terms later adopted by a great number of biospeologists. The “Essai”, called “Racovitza’s famous manifest” by …

Die Bedeutung Der Pleistozänen Vogelfaunen Der Höhlen Im Ungarischen Mittelgebirge, Tibor Farkas

International Journal of Speleology

In the present study, the fossil bird fauna of the caves of the Hungarian Middle Mountains is examined for evidence in support of the hypothesis that the Carpathian Basin may have served as a faunal refugee during the last Quaternary glacial period. As an introduction, the reasons for the refugee hypothesis, including paleobotanical and glacial theoretical aspects, are discussed. Since the first bird fossils of the cave fauna considered in this paper belong to the Würm I-II, the faunistic conditions of the Riss glacial period are not discussed in detail, The known faunas up to the Würm II are interstadial, …

Écologie De Fonticola Notadena De Beauchamp (Turbellarié, Triclade) Dans La Grotte De La Balme (Isère, France); Survie En Période De Sécheresse, René Ginet, Rodolphe Puglisi

International Journal of Speleology

During many months a year the acquatic Planaria (F. notadena) living in a small pool in the La Balme cave are subjected to a drought with the complete drying out of their biotope; they support in situ this lack of water and, living in a latent way inside the clayey matrix. Thanks to the great hygroscopy of the clay, enough humidity stays around the Planarians to enable them to survive. During this period the Planaria may undergo spontaneous divisions resulting in their asexual multiplication.

The Microvegetation Of A Small Ice-Cave In Hungary, Erzsébet Kol

International Journal of Speleology

The algal flora of a small, artificial, ice-cave located in Northern Hungary is described. In this cave 23 species of algae (see in Table 3) were found of which the Cyanophyta and Chlorophyta occurred with approximately equal number. (9 vers. 11) It was found that the primary limiting factor influencing the penetration of the algae into the cave is the low temperature and not the lack of light.

Processes Of Limestone Cave Development, Alan D. Howard

International Journal of Speleology

Three processes successively predominate in enlarging original fractures within limestone into cavern passages: (1) early dissolving by acid produced by oxidizing reactions within the groundwater as it flows through the limestone; (2) dissolving caused by the initial undersaturation with respect to calcite of the groundwater when it enters the limestone; and (3) increased dissolving which occurs at the transition from laminar to turbulent groundwater flow. Only those original fractures in limestone which are widest and which have a high hydraulic gradient acting across them will be enlarged into cavern passages. Until all available surface drainage has been diverted underground, cavern …

I. Preparation And Properties Of Alkyl And Aryl Substituted Thioquinazolines And Sulfoxides ; Ii. An Investigation Of The Quinazoline 3-Oxide--1,4-Benzodiazepine 4-Oxide Rearrangement, Marvin C. J. Kuchar

Theses and Dissertations

I. The quinazolines, a branch of the benzodiazine class of aromatic nitrogen hetercycles, do not occur to any great extent in naturally occurring compounds. The discovery of the antimalarial febrifugine and its structure elucidation led to the preparation and investigation of a host of new quinazolines in the search for new and more effective antimalarials. Most of the present body of information governing the quinazolines arose out of these synthetic studies. The present study has been accomplished with a four-fold purpose in mind: (1) to investigate the susceptibility of chloroquinazolines to nucleophilic displacement reactions by thiols or their salts, (2) …
