Algological Studies In The Cave Of Mátyás Mount, Budapest, Hungary, Lajos Hajdu

International Journal of Speleology

Experiments were designed to test the ability of the aphotic speleoenvironment to support algal growth. The first series contained gelatin cultures of Scenedesmus placed in the cave at different localities in order to establish whether or not the microhabitats have any particular effect on the multiplication of the algae. No differences were found in the cultures after a three month incubation period in the cave, which could be traced to influences of microenvironmental conditions. Chlorella cultures in sterile Knop’s solution showed measurable growth in the cave whereas if the cultures were installed into sterilized cave water or were shielded by …

Über Höhlenbewohnende Moose, László Vajda

International Journal of Speleology

Among the mosses collected by Dr. K. Verseghy in the caves of the environment of Lillafured Eucladium verticillatum (L.) Br. Eur. was found which had some peculiar bulbillae composed of two to many cells on the ends of the filaments. They may represent special reproductive organs as yet unknown in this genus. None of the mosses living in the caves developed sex organs.

Calcite-Aragonite Speleothems From A Hand-Dug Cave In Northeast Kansas, Frederic R. Siegel, Wakefield Dort Jr.

International Journal of Speleology

Speleothems in the form of stalactites, linear stalactitic growths, flowstone, and crusts, from a hand-dug cave in Northeast Kansas (Sec. 2 NENW, T2S, R22E) are composed of calcite and aragonite. If the estimated age of the cave is correct, i.e., 150 to 200 years old, the stalactites have grown at a maximum rate of 0.20 to 0.15 millimetres per year along their vertical axes. All of the speleothems examined contain about one percent strontium (based on qualitative emission spectrograph analyses). Rate of supply and evaporation of the vadose waters may dictate whether aragonite or calcite is the polymorph that precipitates …

Les Crustacés Du Réservoir De La Fontaine Des Suisses À Dijon, Bernard Dussart, François Graf, Roger Husson

International Journal of Speleology

Inventory of the Crustaceans collected in the basin of the Fonatine des Suisses at Dijon. The Copepoda are represented by 5 species: Macrocyclops albidits, Eucyclops serrulatus in two slightly different forms, Eucyclops serrulatus var. mihi, Acanthocyclops venustus, Acanthocyclops vernalis and Acanthocyclops robustus. The coexistence of these two last forms in this very tiny environment makes it probable that we have here to do with two distinct species. A determination key is given for the Genus Acanthocyclops. Amphipoda are represented by Niphargus virei and especially Niphargus kochianus kochianus of which more than 100 samples have been …

Cultivation : Does Haste Mean Waste?, H M. Fisher

Journal of the Department of Agriculture, Western Australia, Series 4

Many farmers believe that increasing the speed of cultivation and seeding implements will cause deterioration of soils and reduced crop yields.

In a three-year trial on clover ley land at Wongan Hills higher cultivation speeds tended to increase rather than decrease wheat yields. There was some deterioration in the physical structure of the soil.

Ecology And Distribution Of Foraminifers Of A Traverse In The Northwestern Gulf Of Mexico, Faiz Nassir Thomas

Masters Theses

"Foraminiferal populations have been analyzed from five bottom samples along a traverse in the northwestern Gulf of Mexico, approximately 27⁰20' to 97⁰15' north latitude and 97⁰20' to 97⁰05' west longitude. Eighty-eight species and twenty-nine genera, belonging to eighteen families, were recorded. Species were identified and described.

Statistical studies indicate that probably five benthonic foraminiferal depth facies could be recognized in the area at the following approximate depths: 4 fathoms, 4-8 fathoms, 8-12 fathoms, 12-16 fathoms, and 16-20 fathoms. Determination of facies is based largely on the range of species. The frequency distribution of species of foraminifers was plotted against change …

Masters Theses

"Values of heat flow through a Precambrian mineral deposit were determined in the Boss area of Missouri, where 350 meters of Paleozoic sedimentary rocks overlie a complex series of rhyolite flows which have been altered and contain a copper bearing magnetite deposit. Geothermal data were obtained from a closely spaced grid of 17 diamond drill holes penetrating to depths of 1000 meters below ground surface. Temperature measurements were made at 5 meter intervals in the Precambrian section of all holes. These and thermal conductivity measurements made on representative core samples from 300 to 400 meters below the top of the …

Structure Contours On The Top And Base Of The M Bed, The Relationship Of Mineralization To Structures, And The Variation Of The M Bed Thickness In The Tri-State District, Missouri, Kansas And Oklahoma, Arvind A. Desai

Masters Theses

"Regional structure and thickness of a single horizon, the M bed, have been studied in the Tri-State district by picking the top and base of the M bed in the logs of 557 selected drill holes and contouring this data together with the aid of local detailed structural information available for individual mining fields. Structures determined from these data were compared to the positions of mined mineralization to determine the control of regional structure upon the localization of ore. Variations in the M bed thickness were compared to the positions of fields of mineralization to examine possible spatial relationships which …

Tectonic Analysis Of Mare Humorum On The Lunar Surface, Adnan Said Abul-Husn

Masters Theses

"Morphology and internal structures of surface features of the Mare Humorum area were interpreted from photographs and topographic maps. The postulated origin of certain features is based on analog comparisons with known terrestrial features. The laws of crate ring and a newly developed computer program were applied to two representative classes of craters to determine the possibility of a meteoritic impact origin. Some of the craters formed by meteoritic impact and others, including those with a radius larger than 10 Km, probably resulted from volcanic activity.

Mare Humorum formed from centripetal subsidence followed by extensive lava eruptions. Spacially related rilles …

A Mathematical Study Of Voigt Viscoelastic Love Wave Propagation, David Nuse Peacock

Masters Theses

"This research is a mathematical investigation of the propagation of a Love wave in a Voigt viscoelastic medium. A solution to the partial differential equation of motion is assumed and is shown to satisfy the three necessary boundary conditions. Velocity restrictions on the wave and the media are developed and are shown to be of the same form as those governing the elastic Love wave"--Abstract, page ii.

Two-Dimensional Seismic Model Studies, Joong Hee Chun

Masters Theses

"The purpose of this research was to design and construct apparatus suitable for two-dimensional seismic model studies.

A new technique for two-dimensional seismic model testing was devised which allows wide application of the equipment. This enabled the author to place the source and receiver in any desired position on the model, thereby permitting the recording of seismic events as function of distance and depth at any position

Two simple geometric models were tested to demonstrate the experimental range of the apparatus designed. The recorded data were compared with theoretical predictions and were found to be in good agreement"--Abstract, page ii.

Origin And Factors Affecting Distribution Of Solid Oil In Mid-Western Missouri, Rafid Abdul-Halim Jasim

Masters Theses

"A textural analysis was made of the heavy oil-bearing sandstones in the Middle Pennsylvanian (Desmoinesian) Warner and Bluejacket formations of mid-western Missouri in order to determine and compare their depositional environments.

Grains of the Bluejacket sandstones are smaller and more rounded than grains of the Warner sandstones. The Bluejacket sandstone is also better sorted than the Warner sandstone.

The Bluejacket sandstone is thin-bedded; the Warner is mostly massive-bedded. These differences in bedding between the two formations have affected distribution of oil in the area of study.

Both the Bluejacket and Warner sandstones are better sorted than the Warrensburg sandstones; the …

Surficial Geology Of Northern Griggs County, North Dakota, Laverne C. Rude

Theses and Dissertations

Griggs County, situated in the Western Lake section of the Central Lowland province, covers an area of 720 square miles in east-central North Dakota. The surface of the county is mantled with three, or possibly four Pleistocene drift sheets, separated by outwash deposits. These drift sheets lie unconformably on the Cretaceous Pierre Shale which is exposed in the Sheyenne River valley and the Binford Hills. Because the drift sheets have similar lithologic and physical characteristics, and are all late Wisconsin in age, they fulfill the requirements for a lithostratigraphic unit and are being considered for designation as part of the …

Algae From The Cave Of Mátyás Mount, Budapest, Hungary, P. Palik

International Journal of Speleology

Seven collections containing scrapings of speleoclay or samples from the cave waters were received from L. Hajdu and were cultured in light in a modified Knop’s solution. The cultures yielded 21 different algal taxa, of which five species belong to the Cyanophyta four to the Bacillariophycaea class of the Chrysophyta and twelve to the Chlorophyta. From the species distribution, the cave shows a similarity to the nearby cave of Pàlvolgy, namely both of them contained more than 50 per cent Chlorophyta. Among the Cyanophyta the occurrence of Baradlaia speluncaecola Palik is noteworthy. This species seems to be a true troglobitic …
