Jurassic Eolian Oolite On A Paleohigh In The Sundance Sea, Bighorn Basin, Wyoming, Zoran Kilibarda, David Loope Aug 2015

Jurassic Eolian Oolite On A Paleohigh In The Sundance Sea, Bighorn Basin, Wyoming, Zoran Kilibarda, David Loope

David B. Loope

Aeolian limestones are widespread in the Quaternary record and have been identified in outcrops and cores of late Palaeozoic strata. These rocks have been interpreted as a low latitude signal of glacio-eustatic sea level fluctuations and have not been previously reported from the Mesozoic or from other episodes of earth history generally believed to have been non-glacial. Numerous lenticular bodies of cross-stratified oolite lie near the contact between the lower and upper members of the mudstone-dominated lower Sundance Formation (Middle and Upper Jurassic) in the Bighorn Basin of north-central Wyoming, USA. The lenses, up to 12 m thick, contain sedimentary …

The paper presents the results of measurements of air emissions of heavy metals from hazardous waste incineration in a multiple hearth furnace and a rotary kiln incinerator equipped with a single wet flue gas cleaning systems. In the multiple hearth furnace an industrial sewage sludge (from coke industry) was being incinerated. In the rotary kiln such wastes were being incinerated as: waste paints, varnish and lubricant, coal tars waste, contaminated cleaning rags, sawdust and used gloves, waste resins and plastics, rubber waste, outdated pharmaceuticals and medicines, and hospital waste. The research allowed us to determine the levels of pollutant concentrations …


Zastosowanie Modelu "Skrzynki" Do Oceny Poziomu Stężeń Zanieczyszczeń Komunikacyjnych W Przyziemnej Warstwie Atmosfery, Marek Bogacki, Marian Mazur, Robert Oleniacz Dec 1997

Zastosowanie Modelu "Skrzynki" Do Oceny Poziomu Stężeń Zanieczyszczeń Komunikacyjnych W Przyziemnej Warstwie Atmosfery, Marek Bogacki, Marian Mazur, Robert Oleniacz

Robert Oleniacz

Road transport is an essential source of nitrogen oxides (NOx), carbon monoxide (CO) and reactive hydrocarbons (RHC) emissions to atmosphere. Quantity and chemical constitution of emitted substances and meteorological conditions determine the level of ozon (O3) concentration forming as a result of photochemical reactions. The method presented in the paper consists in designation of quantity and chemical constitution of substances emitted from mo-bile sources and special mathematical modeling of physical and chemical transformations that take place in the lowest atmospheric layer.

English title: The use of box model to estimate the size of traffic pollutant concentrations in the lowest atmospheric …

Christopher Spilling

The crystal structure of the racemic title compound, C18H20NO6P, m.p. 428-431 K, has been determined by X-ray diffraction. The title compound consists of a tetrahedral P atom bonded to two methoxy groups, and an alkyl chain. The alkyl chain was substituted at position 1 with a carbamate and with an epoxide at positions 2 and 3. The relative configuration of the 1-carbamate and 2,3-epoxide substituents was confirmed as anti (1S,2R,3S). The crystal structure contains an enantiomeric pair with two intermolecular hydrogen bonds in a 14-membered ring. The hydrogen bonds are formed between the P=O of one enantiomer and the N-H …

Combining Multi-Attribute Utility And Geographic Information For Boundary Decisions: An Application To Park Planning, Jeffrey Keisler, Ronald Sundell Nov 1997

Combining Multi-Attribute Utility And Geographic Information For Boundary Decisions: An Application To Park Planning, Jeffrey Keisler, Ronald Sundell

Jeffrey Keisler

The quality and value of an area depend primarily on what is found within
its designated boundaries. To determine the value of such areas in terms of boundaries,
we have developed a methodology for integrating multi-attribute utility functions with
spatial analysis so that desirable, or appropriate, boundaries can be determined on the
basis of the goals and objectives for the park. The key to successful evaluation is the
development of measures for what decision makers value, rather than merely using
what is easily measured. In a detailed example for planning of national parks, the
fundamental objectives are conservation and societal …

Photolithographic Patterning Of Vacuum-Deposited Organic Light Emitting Devices, Peifang Tian, P. E. Burrows, S. E. Forrest Nov 1997

Photolithographic Patterning Of Vacuum-Deposited Organic Light Emitting Devices, Peifang Tian, P. E. Burrows, S. E. Forrest

Peifang Tian

We demonstrate a photolithographic technique to fabricate vacuum-deposited organic light emitting devices. Photoresist liftoff combined with vertical deposition of the emissive organic materials and the metal cathode, followed by oblique deposition of a metal cap, avoids the use of high processing temperatures and the exposure of the organic materials to chemical degradation. The unpackaged devices show no sign of deterioration in room ambient when compared with conventional devices fabricated using low-resolution, shadow mask patterning. Furthermore, the devices are resistant to rapid degradation when operated in air for extended periods. This work illustrates a potential foundation for the volume production of …


A Vegetation Based Approach To Biodiversity Gap Analysis In The Agastyamalai Region, Western Ghats, India, B. R. Ramesh, Shaily Menon, Kamaljit S. Bawa Nov 1997

A Vegetation Based Approach To Biodiversity Gap Analysis In The Agastyamalai Region, Western Ghats, India, B. R. Ramesh, Shaily Menon, Kamaljit S. Bawa

Shaily Menon

Protected areas in India have historically been established on an ad hoc basis with little attention to the conservation value of an area. This study focuses on a set of protected areas in the Agastyamalai region of the Western Ghats (WG), India. We examine forest loss and land-use changes in the study area from the early 1900s to 1960 and from 1960 to 1990. We use GIS to perform a biodiversity gap analysis of the protected areas in the study site. We produce a detailed map of existing floristic types and use it to generate layers corresponding to floristic species …

Empirical Models Of Storm-Time Equatorial Zonal Electric Fields, Bela G. Fejer, L. Scherliess Nov 1997

Empirical Models Of Storm-Time Equatorial Zonal Electric Fields, Bela G. Fejer, L. Scherliess

Bela G. Fejer

Ionospheric plasma drifts often show highly complex and variable signatures during geomagnetically active periods due to the effects of different disturbance processes. We describe initially a methodology for the study of storm time dependent ionospheric electric fields. We present empirical models of equatorial disturbance zonal electric fields obtained using extensive F region vertical plasma drift measurements from the Jicamarca Observatory and auroral electrojet indices. These models determine the plasma drift perturbations due to the combined effects of short-lived prompt penetration and longer lasting disturbance dynamo electric fields. We show that the prompt penetration drifts obtained from a high time resolution …

A Control Basis For Learning Multifingered Grasps, Jefferson Coelho, Roderic Grupen Oct 1997

A Control Basis For Learning Multifingered Grasps, Jefferson Coelho, Roderic Grupen

Roderic Grupen

In this paper, we introduce a robust controller that uses contact position and normal feedback to generate contact configurations for statically stable grasps. The approach uses a context sensitive composition of two controllers that minimize force and moment residuals in the grasp configuration. We show that equilibria in the composite controller correspond to optimal contact configurations for 2 and 3 contacts on regular, convex polygons. The preimage is used to generalize the controller to arbitrary object geometries by learning a policy for compensation and to address object recognition, and contact (de)allocation.

Structure Factors And Their Distributions In Driven Two-Species Models, G. Korniss, Beate Schmittmann Oct 1997

Structure Factors And Their Distributions In Driven Two-Species Models, G. Korniss, Beate Schmittmann

Beate Schmittmann

We study spatial correlations and structure factors in a three-state stochastic lattice gas, consisting of holes and two oppositely “charged” species of particles, subject to an “electric” field at zero total charge. The dynamics consists of two nearest-neighbor exchange processes, occurring on different times scales, namely, particle-hole and particle-particle exchanges. Using both Langevin equations and Monte Carlo simulations, we study the steady-state structure factors and correlation functions in the disordered phase, where density profiles are homogeneous. In contrast to equilibrium systems, the average structure factors here show a discontinuity singularity at the origin. The associated spatial correlation functions exhibit intricate …


Deuteron Threshold Electrodisintegration At High Momentum Transfer, W M. Schmitt, K S. Lee, H Baghaei, S Churchwell, R S. Hicks, R Miskimen, Gerald Alvin Peterson, K Wang Oct 1997

Deuteron Threshold Electrodisintegration At High Momentum Transfer, W M. Schmitt, K S. Lee, H Baghaei, S Churchwell, R S. Hicks, R Miskimen, Gerald Alvin Peterson, K Wang

Gerald Alvin Peterson

Absolute differential cross sections for the threshold electrodisintegration of the deuteron with good resolution were measured at a laboratory scattering angle of 160° for five values of Q2 ranging from 8.66 to 42.4fm-2. Comparisons of the data averaged over Enp from 0 to 3 MeV and from 0 to10 MeV are made with nonrelativistic meson exchange calculations. These calculations are sensitive to the nucleon electromagnetic form factors, nucleon-nucleon potential, and relativistic effects. The data are also compared with a hybrid quark-hadron model calculation that describes the deuteron as a six-quark cluster for the short range part of the interaction. Some …

Spalanie Odpadów Poszpitalnych I Farmaceutycznych W Piecu Obrotowym / Incineration Of Hospital And Pharmaceutical Wastes In A Rotary Kiln Incinerator, Robert Oleniacz, Marian Mazur, Marek Bogacki

Robert Oleniacz

The paper presents selected results of research on hospital and pharmaceutical waste incineration in a full-scale rotary kiln with variable loads of the kiln. As part of these studies measurements of air pollutant concentrations in flue gases and leaching tests of solid combustion products were carried out. Based on these studies, the maximum dose of hospital and pharmaceutical waste was proposed in the mixture with industrial wastes, which does not cause excessive air emissions. The average emission factors for the waste mixture loading were also determined.

The need to perform an environmental impact assessment for objects of this type results from the binding legal regulations in Poland. The analysis included all the main components of the environment: air, soil, vegetation, soil and water environment, land surface and acoustic climate. It was found that …


Segregation Of Bismuth To Triple Junctions In Copper, K.-M. Yin, Alexander H. King, T.E. Hsieh, F.-R. Chen, J.J. Kai, L. Chang Sep 1997

Segregation Of Bismuth To Triple Junctions In Copper, K.-M. Yin, Alexander H. King, T.E. Hsieh, F.-R. Chen, J.J. Kai, L. Chang

Alexander H. King

Bismuth segregation in copper has been studied using energy-dispersive X-ray spectrometry (EDX) in a JEOL 2010F transmission electron microscope. In addition to the expected solute enrichment at grain boundaries, we have observed extremely high concentrations of bismuth at certain triple junctions, with significantly greater enrichment factors than in the adjacent grain boundaries. It is shown here that the triple junction segregation is a function of the parameters of the grain boundaries at the triple line, and existence of this type of segregation implies that the affected triple junctions embody excess free energy. At least one of the observed triple junctions …
