Un Nouveau Microparasellide Des Eaux Souterraines Phréatigues De I'Italie: Microcharon Arganoi N. Sp. (Crustacea: Isopoda), Giuseppe L. Pesce, Pierantonio Teté

International Journal of Speleology

Microcharon arganoi, a new Microparasellid from subterranean waters of Southern Italy is described. For the shape and ornamentation of pleopod II of females and for the morphology of pleopod II of males, the new species is clearly related to the phyletic line which includes all the Western and French species of the genus. However, from all these species and from all the other ones M. arganoi differs by the ornamentation of the antennae, maxillipeds and pereiopeds, by the shape and ornamentation of pleopods I and II of males and II of females. and by ratio endopod/exopod of pleopod III. …

The Fine Structure Of Hamann's Organ In Leptodirus Hohenwarti, A Highly Specialized Cave Bathysciinae (Coleoptera, Catopidae), Fiorenza Accordi, Valerio Sbordoni

International Journal of Speleology

Hamann’s organ in Leptodirus hohenwarti a highly specialized cave Bathysciinae, has been studied under the TEM, SEM and light microscope. This receptor organ located in the 7th, 9th and 10th antennal articles and previously referred to as the “vesicule olfactive” and as the “antennal organ” or “antennal vesicle”, reaches its highest degree of structural complexity in leptodirus. This paper attempts to establish some degree of synonymy among the terms used by earlier authors in describing the various antennal parts and sensilla. Five types of sensilla to be found in the organ are described, namely cribrose-stick sensilla, cribrose-utricular sensilla, star-shaped sensilla, …

Humidity Responses And The Role Of Hamann's Organ Of Cavernicolous Bathysciinae (Coleoptera Catopidae), Marco Lucarelli, Valerio Sbordoni

International Journal of Speleology

The humidity responses of Bathysciola derosasi and Leptodirus hohenwarti, two species of troglobitic Bathysciinae showing different degrees of adaptation to cave environment, have been studied. Intact and antennectomised subjects were tested using choice-chambers with various combinations of relative humidity alternatives (i.e. 20-100%, 50-100%, 90-100%, 50-90% and, as controls, 100-100%) to investigate the role played by the sense organs situated on the 7th, 9th and 10th antenna segments. The results show that intact-antenna subjects of both species are very sensitive to humidity gradients and that their intensity of reaction varies according to the intensity of stimulus, as previously reported by …

Ostracodes Hypogés Du Sud De La France. 1. Mixtocandona Juberthieae N.Sp., Dan L. Danielopol

Magniezia Gardei N.Sp. (Crustacca Isopoda Asellote): Un Sténasellide Des Eaux Souterraines Du Maroc Sud-Oriental, Guy Magniez

International Journal of Speleology

This new species has been discovered in the waters of Kef Aziza Cave, on the Saharian slopes of the High Atlas Range, Southeastern Morocco. Magniezia gardei n.sp. belongs to the same Genus as four species previously described from the phreatic waters of the Guinean area. So, it is assumed that this Moroccan species should be a relict of the ancient aquatic hypogean fauna of the entire West Africa, nowadays protected by the development of an arid climate.

Microflore Et Activité De Groupements Fonctionnels Dans Les Sédiments De Trois Grottes De I'Italie Centrale, A. Pasqualini, B. Fumanti, L. Visonà

International Journal of Speleology

A comparative study is presented of the microflora of sediments in three caves with different trophic characteristics. Quantitative and qualitative variations of microflora were investigated for one year by studying the total microflora and the activity of the nitrogen cycle functional groups. Data were compared with those of other works of previous authors. Results show that the quantity and kind of organic matter of sediment are most important factors regulating the abundance and activity of cavernicolous microflora. The experimental part of this paper is prefaced by a digest of investigations previously carried out on cavernicolous microflora and by a report …

Neue Ergebnisse Speläologischer Untersuchungen In Den Hainburger Bergen (Nö) Und Ihre Wissenschaftliche Bedeutung, Karl Mais

International Journal of Speleology

Since 1971 speleological and paleontological investigations have been carried out in the quarry “Hollitzer” which is in the Pfaffenberg near Bad Deutsch Altenburg (Hainburger Berge, Lower Austria). Evident karst phenomena are missing at the surface, but the existence of caves filled with sediments in the quarry show that the area is a fossil buried karst. A steady scientific survey allowed the study of the karstic phenomena without hindering the work in the quarry. Up to now more than 150 cavities have been discovered. Most of them seem to belong to a unique solutional system; corrasive forms are missing. Fossils (Gasteropoda, …

Un Batrachuperus Adulte Dans Une Grotte D'Iran Espèce Nouvelle?, M. Clergue-Gazeau, J. P. Farcy

International Journal of Speleology

During a speleological exploration of a cave in Iran, a species of Urodele Hynobiidae was found. This Batrachian is either a new species of the genus Batrachuperus or an adult form of the species Batrachuperus persieus previously only described in its larval and juvenile forms. Certain observable differences suggest that it can be considered a new species. Observations on its feeding habits indicate that the presence of this periodic trogloxene in the cave is not “accidental”, but that it remains there for a long period during its life cycle.

Fracturation Et Karstification D'Un Massif: L'Exemple De L'Azerou El Kebir (Algérie Du Nord), P. E. Coiffait, Y. Quinif

International Journal of Speleology

The fracturation of the sub-autochthonous massif of the Azerou el Kebir is not fundamentally different from that of the adjoining allochthonous massif - where the structures are due to an Alpine phase, known as the Atlas phase. As with all fractures, karstification only exploits certain of them, without having any linkage to their statistical importance, caves have developed following fractures which are qualitatively important, but are poorly represented quantitatively. The study of the karstification therefore, confirms his complementary to the structural analysis in order to elucidate the technical problems of fracturation in the region.

The Development Of Limestone Cave Systems In The Dimensions Of Length And Depth, Derek Clifford Ford, R. O. Ewers

International Journal of Speleology

Karst caves are defined as solutional cavities 5-16 mm in diameter and discussion is limited to cases where such continuously extend to a surficial input or output or both. Three opposed sets of general genetic hypotheses (“the classical hypotheses”) have been presented for such caves, Arguing that the majority develop 1) in the vadose zone 2) in the phreatic zone 3) proximate and parallel to a watertable. It is contended here that vadose, phreatìc and watertable caves are all of common occurrence and may be linked in one genetic theory. A four state model is proposed in which ideal phreatic …

Adolph Schmidl (1802 - 1863) The Father Of Modern Speleology?, T. R. Shaw

International Journal of Speleology

A. Adolf Schmidl (1802-1863) was the first person to regard speleology as a single coherent subject. Besides making important new explorations, he studied karst hydrology and underground meteorology and was also closely concerned with the work of others on cave fauna and flora. His publications ensured that his achievements were known to his successors, but his influence was less widespread than that of Martel who nevertheless called him “the real originator of speleology”.

Synthèse Bibliographique Sur La Toxicité Des Substances Fluorescentes Utilisées En Hydrologie, J. Molinari, J. Rochat

The adjoining annex gives an exhaustive use of publications received on the subject (35 titles).

The Discovery Of Proteus-Eggs (Proteus Anguinus Laurenti, Amphibia) In Seminatural Conditions, B. Sket, F. Velkovrh

International Journal of Speleology

Proteus-eggs were found for the first time in the nature, drifted out of a karstic spring. They were obtained from the Vir Spring al Sticna, 30 km ESE of Ljubljana. The hydrological and faunistical data indicate that Proteus lays its eggs also in “unsheltered”, energetically rich groundwater habitats.

Observations Sur I'Écologie Et La Distribution Des Turbellariés Tricladides Dépigmentés Et Anophtalmes De Roumanie, L. Botosaneanu

International Journal of Speleology

Twenty-two localities, where unpigmented and mostly blind tricladid turbellarians (Dendrocoelidae and Fonticola) were discovered by the author, are described in more or less detail. These animals are particularly well represented in Romania; the explanation is that they are expansive offshoots of a fauna formerly inhabiting the huge brackish or freshwater lakes which covered most of this country during the Neogene (and especially the Sarmatian). Different species are inhabitants of different particular habitats of the underground water realm, and the author distinguishes between species inhabiting cave waters, typical phreatobionts, hyporheic species and species living in springs or springbrooks. These species are …

Réponses Locomotrices Du Poisson Cavernicole Astyanax Jordani (Pisces, Characidae) À Des Signaux Périodiques Et Apériodiques De Lumière Et De Température, G. Thines, M. Weyers

International Journal of Speleology

The locomotory activity of adult cave fishes Astyanax jordani was recorded in isolation in the following light and temperature conditions: constant conditions (100 Lx - 20°C), in a light cycle (LD:11/11 -10 Lx -100 Lx) and in a temperature cycle (11/11; 17/20, 19/22, 20/23, 27/30 °C). All longitudinal time series extended for a minimum of 30 days. Results show: (1) That no circadian regulation appears in constant conditions; (2) that passive entrainment occurs in LD (Amplitude: 90 Lx) and in periodic temperature conditions (Amplitude: 3°C). The entrainment effect damps out and varies individually; (3) that the mean activity increases with …

He then reviews the 9 species of Chiroptera that live in the subterranean field in Shaba, pointing out their environmental habitat, behaviour and parasites.

Developmental Dyslexia: Evidence For A Subgroup With A Reversal Of Cerebral Asymmetry, Daniel B. Hier, Marjorie Lemay, Peter B. Rosenberger, Vincent P. Perlo

Chemistry Faculty Research & Creative Works

The Computerized Brain Tomograms of 24 Patients with Developmental Dyslexia Were Analyzed for Cerebral Asymmetry. Ten Patients Showed a Reversal of the Pattern of Asymmetry Regularly Observed in Normal Right-Handed Individuals So that the Right Parietooccipital Region Was Wider Than the Left. the Ten Dyslexic Patients with This Reversal of Cerebral Asymmetry Had a Lower Mean Verbal IQ Than the Other 14 Dyslexic Patients in This Study. the Reversal of Cerebral Asymmetry that Occurred in Ten of the Dyslexic Patients May Result in Language Lateralization to a Cerebral Hemisphere that is Structurally Less Suited to Support Language Function and Thus …

Some Results On Inferences For The Gamma And Double Exponential Distributions, John Victor Grice

Doctoral Dissertations

"This dissertation is presented in publication form and consists of two articles. The first article considers testing the mean of a gamma distribution. For the case that both parameters in the ganuna distribution are unknown, approximate tests for the mean are derived and tables are provided for their implementation. The power of the tests are compared to the power of the uniformly most powerful tests on the mean when the shape parameter is known. In addition, some limiting results are derived. The second article compares conditional and unconditional methods of constructing confidence intervals for the location parameter in the two-parameter …

Landsat Image Analysis Of Linears And Lineaments In The Tri-State District, Missouri-Oklahoma-Kansas, Solomon Hartley Toweh

Masters Theses

"Lineations within the Tri-State mining district are classified as megalineaments, lineaments and linears, based on length. One megalineament, 120 lineaments and 205 linears are identified on the LANDSAT imagery. In order of importance a dominant northeast set, northwest set, north-south set and east-west set are recognized. These range from 0.8 miles (1.3 km) to 68 miles (109.4 km) in length.

Major lineation trends spatially relate with trends of mined areas In the Picher field both northeast and northwest lineations generally parallel mined areas. In the Galena field ore and lineations trend northeast while in the Joplin and Duenweg-Webb City-Oronogo field …

Sedimentology Of The Hannibal Formation In Northeastern Missouri And Western Illinois, Michael Harry Deming

Masters Theses

"The Hannibal Formation (Kinderhookian) occurring in northeastern Missouri and western Illinois is a fine-grained, terrigenous, sedimentary unit which can be divided into an upper and a lower portion, based on lithology. The upper portion consists of alternating coarse and argillaceous, fine siltstone units, while the lower portion consists of a silty mudstone with an occasional thin siltstone unit. At the extreme western margin of the formation, near where the Hannibal almost pinches out, the formation consists entirely of a silty claystone. Extending southward along the study area, the coarse siltstone units of the upper Hannibal become thinner, and eventually pinch …

Precipitation Phenomena In Antimony-Implanted Aluminium, Richard Allen Kant

Physics & Astronomy ETDs

An experimental and theoretical study of the influence of temperature flux, and fluence on the formation and evolution of compounds formed by ion implantation has been conducted. Transmission electron microscopy was used to determine the size distribution of AJSb precipitates resulting from implanting single crystal A1 with Sb. In addition, the role of ion damage was investigated using both Ar and Al bombardment. These experiments show that for samples which initially contain no Sb, the number density of pre• cipitates decreases with increasing fluence and temperature, and with decreasing flux.

A Petrochemical Characterization Of Certain Dsdp Subaqueous Basalts And Andesites From The Indian Ocean, John Lee Berkley

Thirty-eight samples of Indian Ocean subaqueous basalt and andesite recovered by the Deep-Sea Drilling Program (DSDP) were analyzed by the following methods: (1) standard petrographic analysis, (2) electron microprobe analysis of major minerals, (3) bulk-rock analyses for major, minor, and trace elements, including eight rare earth elements (REE), and (4) determination of 87Sr/86Sr by mass spectroscopy. A varied suite of basement igneous rocks was studied, including (1) abyssal tholeiites, (2) ferrobasalts, (3) oceanic andesites, (4) transitional basalts (high-Al basalts), and (5) trachybasalts.

Synthesis And Studies Of A Carbon-13 Labelled Chemical Carcinogen, Robert E. Royer

Chemistry and Chemical Biology ETDs

Derivatives of 6-methylbenzo[a]pyrene enriched to 90% carbon-13 at the methyl carbon were synthesized. Reactions of the carcinogen, 6-chloromethylbenzo[a]pyrene, with nucleophiles under solvolytic conditions were studied kinetically and, using labelled 6-chloromethylbenzo[a]pyrene, the reaction products were studied by CMR. The purpose was to characterize the selectivity of the benzo[a]pyrenyl- 6-methyl carbonium ion in its reactions with some simple nucleophiles and with nucleosides and other nucleic acid components.

Although the solvolysis of 6-chloromethylbenzo[a]pyrene in aqueous/organic solution is first order, information about the course of the reaction can be obtained, under certain circumstances, from rate constants. Thus, if the rate of solvolysis is slowed …

Physical Studies Of Hg(Ii) And Ag(I) Dna Complexes, Dawen Ding

Chemistry and Chemical Biology ETDs

The binding of Hg(II) and Ag(I) to the bases of DNA and polynucleotides induces strong absorption and CD bands. From electric dichroism studies, the transition moment of the difference absorption band at 293 nm is in the plane of the bases and has a huge negative CD band at 285 nm; while the corresponding 293 nm difference absorption band of DNA-Ag(I) complex is relatively CD inactive. A second band at 270 nm in the difference absorption spectrum of the DNA-Ag(I) complex has a large associated CD band at 270 nm. This transition is out of the plane of the bases. …

Photochemical Studies Of Hydroxo-Bridged Complexes Of Chromium (Iii), Ronald Raymond Ruminski

Chemistry and Chemical Biology ETDs

The acid solution and solid state photolysis in both visible and ultraviolet regions of the spectrum for µ-hydro­xo-bis[pentaamminechromium(III)] chloride, and the solution photolysis in the visible and 1 traviolet region of the spectrum for µ-hydroxo-bis[pentaarnrninechr rnium(III)] perchlorate, have been studied. The ultraviolet irradiation of µ-hydroxo-bis[pentaamminechromium(III)] chloride in HCl and CHlO₄ produces a redox photoproduct identified as HCrO₄^-, although the rate of production of HCrO₄^- in HClO₄ is slower than in HCl. Photochemical cleavage of the hydroxo-bridge occurs in the ultraviolet photolysis of µ -hydroxo-bis[pentaanuninechromium(III)] chloride and is 1.9 times faster than the corresponding …
