Emisja Chlorowodoru Ze Spalania Węgla W Kotle Pyłowym, Marian Mazur, Robert Oleniacz, Przemysław Szczygłowski, Marek Bogacki

Robert Oleniacz

Emission of hydrogen chloride (HCl) from coal combustion is not controlled just like for example sulpfur dioxide emission. But HCl emission is also important, because chlorine content in some types of coal can reach the similar level to sulfur content. In the paper the measurement results of HCl emission to the air during combustion of three types of coal with law content of chlorine were presented. The researches were carried out for a steam pulverized coal boiler (max. boiler efficiency – 430 t/h) during three various loads (respectively 65, 80 and 95 % of maximum efficiency) without flue gas desulfurization. …

Metoda Oceny Trudności Oczyszczania I Toksyczności Spalin Powstających Podczas Spalania Odpadów, Robert Oleniacz

Robert Oleniacz

The paper presents a methodology for evaluating the cleaning difficulty and toxicity of combustion gases from waste incineration based on the knowledge of gases composition. This type of evaluation may be applicable to selection or modernization of flue gas cleaning systems for waste incineration plants and to comparative analy-sis of a pollution degree of raw (unclean) combustion gases. In the evaluation of the cleaning difficulty of gases six categories of difficulty have been identified for removal of selected substances or groups of substances. The evaluation is made individually for substances or groups of substances on condition their concentrations in flue …

Surface Structure Of Alkylsilylated Hzsm-5 As Phase-Boundary Catalyst, Hadi Nur, Yun Hau Ng, Mohd Nazlan Mohd Muhid, Halimaton Hamdan

Yun Hau Ng

The need for cleaner environment concerns motivates the development of more efficient catalytic system. Based on this consideration, recently a novel catalyst named "Phase-boundary catalyst", a bimodal amphiphilic solid catalyst, was proposed. It was demonstrated that the catalytic system containing phase-boundary catalyst required neither stirring to make an emulsion nor addition of a co-solvent to make a homogeneous solution to drive the reaction. The driving force that has prompted this paper is to investigate the surface structure of alkylsilylated HZSM-5 as phase-boundary catalyst. Temperature Programmed Desorption (TPD) of ammonia and, 13C and 29Si MAS NMR spectroscopy were used to elucidate …

Emisja Btx Towarzysząca Produkcji Wyrobów Węglowych I Grafitowych, Marian Mazur, Przemysław Szczygłowski, Robert Oleniacz, Marek Bogacki

Robert Oleniacz

The work presents results of direct measurements of benzene, toluene, ethyl benzene and xylenes (BTX or BTEX) emissions to the air from technological processes related with carbon and graphite manufacturing. The most important from all mentioned pollutants is benzene considered as one of the main factor of air pollution in the European Union. The highest concentrations of BTX were found in the fumes emitted from the tanks of liquid raw materials, while the highest levels of their emissions were from furnaces used for baking of green electrodes and other carbon products.

English title: BTX emission from production of graphite and …

Ecological And Agricultural Applications Of Synchrotron Ir Microscopy, Ted K. Raab, John P. Vogel

Ted K. Raab

The diffraction-limited spot size of synchrotron-based IR microscopes provides cell-specific, spectrochemical imaging of cleared leaf, stem and root tissues of the model genetic organism Arabidopsis thaliana, and mutant plants created either by T-DNA insertional inactivation or chemical mutagenesis. Spectra in the wavelength region from 6 to 12 microns provide chemical and physical information on the cell wall polysaccharides of mutants lacking particular biosynthetic enzymes (‘‘Cellulose synthase-like’’ genes). In parallel experiments, synchrotron IR microscopy delineates the role of Arabidopsis cell wall enzymes as susceptibility factors to the fungus Erysiphe cichoracearum, a causative agent of powdery mildew disease. Three genes, pmr4, pmr5, …

Effects Of Experimental Greenhouse Warming On Phytoplankton And Zooplankton Communities In Fishless Alpine Ponds, Angela L. Strecker, Tyler P. Cobb, Rofl D, Vinebrooke

Angela L. Strecker

The impacts of global warming on aquatic ecosystems are expected to be most pronounced at higher trophic levels in cold-water environments. Therefore, we hypothesized that wanning of fishless alpine ponds would suppress large-bodied consumers (e.g., cladocerans, copepods) and stimulate fast-growing microorganisms (e.g., phytoflagellates, rotifers), thereby altering the community composition and total abundance of zooplankton and phytoplankton. This hypothesis was tested using three blocks of four experimental mesocosms (1000-liter capacity) that were located next to alpine ponds in Banff National Park, Canada. Each block received unfiltered pond water and sediment from a pond following ice out in June 2000. A warming …

Wpływ Wybranych Parametrów Na Wielkość Emisji Zanieczyszczeń Powietrza Z Procesu Wysokotemperaturowego Spalania Odpadów Chloroorganicznych, Robert Oleniacz

Robert Oleniacz

In the paper preliminary analysis of the continuous measurements of the air pollutants emission and other

parameters of high-temperature process of chloroorganic waste incineration (liquid injection incinerator - Vicarb technology) are presented. In the analysis there was taken especially note of the parameters influencing the emissions, which could significantly vary in the incineration system (for example the amount of incinerated wastes) and pollutants like hydrogen chloride, nitrogen oxides and carbon monoxide. Basing the results of the analysis, it was affirmed that chlorine plays an inhibiting role on the formation of nitrogen oxides in the chloroorganic waste incineration system. On the …

Emisja Rtęci Z Energetycznego Spalania Węgla, Marian Mazur, Przemysław Szczygłowski, Robert Oleniacz, Janusz Dańko

Robert Oleniacz

In the paper, some results of the measurement of mercury emission from OP-430 boiler working in the Combustion Plant “Kraków S.A.” are presented. The tests were carried out during combustion of various coals and changeable the boiler efficiency. Apart from investigation of mercury emission to the atmosphere (in gaseous and solid phase), total mercury concentration in coal, bottom ash and dust collected in electrostatic precipitators were analysed as well. Thus emission amount could be verified by means of the approximate mercury balance performed for the coal combustion process.

English title: Mercury emission from coal combustion.

Karst Of Western Cuba: Observations, Geomorphology, And Diagenesis, Larry D. Seale, Limaris R. Soto, Lee J. Florea, Beth Fratesi

Lee J Florea, PhD, P.G.

In Cuba, we observed many karst features in a variety of hydrogeologic settings. These hy-drogeologic settings occur in close proximity only because of the complex tectonic history of the is-land. We observed caves within rocks ranging from Pleistocene to Jurassic, and representing a range of diagenetic ages from eogenetic to teloge-netic. Our observations are from the western one-third of the island of Cuba; however, we believe they are representative of hydrogeologic settings found throughout the island.

Bayesian Sample Size Calculations In Phase Ii Clinical Trials Using Using Informative Conjugate Priors, Matthew S. Mayo, Byron J. Gajewski

Byron J Gajewski

A number of researchers have discussed phase II clinical trials from a Bayesian perspective. A recent article by Tan and Machin focuses on sample size calculations, which they determine by specifying a diffuse prior distribution and then calculating a posterior probability that the true response will exceed a prespecified target. In this article, we extend these sample size calculations to include informative prior distributions using various strategies that allow researchers with both optimistic and pessimistic priors direct involvement in the sample size decision making. We select the informative priors via multiple methods determined by the mean, median or mode of …

Correspondence Estimation Of The Source Profiles In Receptor Modeling, Byron J. Gajewski, Clifford H. Spiegelman

Byron J Gajewski

This article considers the estimation of source profiles from pollution data collected at one receptor site. At this receptor site, varying metrological conditions can cause errors that are possibly a mixture of distributions. A standard estimator utilizes a least squares approach because of its optimal properties under normally distributed errors and consistency under many other distributions. In contrast, we study the behavior of least squares relative to our new approach, which is better suited for dealing with errors having a mixture of distributions. The estimator loses efficiency under normal errors, but in turn gains efficiency while in the presence of …

Everything You Wanted To Know About Licensing Agreements, Gordon C. Tibbitts

Gordon C. Tibbitts III

This presentation explores the intricacies of licensing agreements to help develop strategies for negotiating the broadest possible access to electronic content for a library. Issues such as inter-library loan restrictions, archiving, duplication among aggregator databases, and withdrawal of content are discussed. The process of negotiating licensing agreements and how to identify those clauses that are particularly important or sensitive are described. How to draft library-friendly agreements and collaborative ways librarians and information providers can work together to find solutions to the evolving problems of content access and delivery are described.

Adaptive Agents For Supply Networks, Gavin Finnie, Jeffrey Barker

Jeffrey Barker

Dynamic information flow in esupply networks requires that buyers and suppliers have the ability to react rapidly when needed. Using intelligent agents to automate the process of buyer/seller interaction has been proposed by a number of researchers. One problem in providing intelligent automated collaboration is incorporating learning capability i.e. an agent should be capable of adapting its behaviour as conditions change. This paper proposes a scalable multi-agent system which uses case-based reasoning as a framework for at least part of its intelligence. Tests with a simulated system show that such an agent is capable of learning the best supplier and …

Removing Excess Topology From Isosurfaces, Zoë J. Wood, Hugues Hoppe, Mathieu Desbrun, Peter Shröder

Zoë Wood

Many high-resolution surfaces are created through isosurface extraction from volumetric representations, obtained by 3D photography, CT, or MRI. Noise inherent in the acquisition process can lead to geometrical and topological errors. Reducing geometrical errors during reconstruction is well studied. However, isosurfaces often contain many topological errors in the form of tiny handles. These nearly invisible artifacts hinder subsequent operations like mesh simplification, remeshing, and parametrization. In this article we present a practical method for removing handles in an isosurface. Our algorithm makes an axis-aligned sweep through the volume to locate handles, compute their sizes, and selectively remove them. The algorithm …

1d Energy Transport In A Strongly Scattering Laboratory Model, Kasper Van Wijk, Matt M. Haney, John A. Scales

Matthew M. Haney

Radiative transfer (RT) theory is often invoked to describe energy propagation in strongly scattering media. Fitting RT to measured wave field intensities is rather different at late times, when the transport is diffusive, than at intermediate times (around one extinction mean free time), when ballistic and diffusive behavior coexist. While there are many examples of late-time RT fits, we describe ultrasonic multiple scattering measurements with RT over the entire range of times—from ballistic to diffusive. In addition to allowing us to retrieve the scattering and absorption mean free paths independently, our results also support theoretical predictions in 1D that suggest …

A Log-Normal Distribution Model Of The Effect Of Bacteria And Ear Fenestration On Hearing Loss: A Bayesian Approach, Byron J. Gajewski, Jack D. Sedwick, Patrick J. Antonelli

Byron J Gajewski

Chronic ear infection is a potentially life-threatening illness that medical doctors typically treat with ear surgery. Despite the success of this treatment, complications can occur due to bacteria infection. Surgeons believe that this infection causes the patient to have clinically signigcant hearing damage. In order to understand such complications, surgeons must quantify the effect of bacteria, their toxins and ear surgery on hearing loss. To this end, the other two authors of this paper performed two experiments on guinea pigs to measure hearing thresholds following a bacterial infection and surgery of the inner ear. The response variable in these experiments …

Effect Of Measurement On The Periodicity Of The Coulomb Staircase Of A Superconducting Box, Jaan Männik, J. E. Lukens

Jaan Männik

We report on the effect of the backaction of a single Cooper pair transistor electrometer (E) on the charge state of a superconducting box (B). The charge is e periodic in the gate bias of B when E is operated near voltages 2Δ/e or 4Δ/e. We show that this is due to quasiparticle poisoning of B at a rate proportional to the number of quasiparticle tunneling events in E per second. We are able to eliminate this backaction and recover 2e-charge periodicity using a new measurement method based on switching-current modulation of E.

Porównanie Poprzedniej I Aktualnej Metodyki Modelowania Rozprzestrzeniania Się Zanieczyszczeń W Powietrzu Opartej Na Modelu Smugi Gaussa, Robert Oleniacz, Marek Bogacki

Robert Oleniacz

Necessity of adaptation the Polish law in the field of the environment protection to the European Union law caused to adopt new criterions and methods of the air quality assessment. One of the methods of the air quality assessment is modeling of the substance levels in the air based on the calculation of the air pollutant dispersion in the atmosphere. Thus necessary changes also encompassed the basic methodology applied in our country for many years that had made possible calculation of the air pollution caused by existing and new emission sources. After some modifications the computation method was adopted as …

Light & Dark: The Hidden Wonders Of Buck Creek, Lee J. Florea

Lee J Florea, PhD, P.G.

As early morning mists rise from the banks of its supple waters, beams of light penetrate the Buck Creek valley illuminating its beauty. While light illuminates most of the land, there are secret places, nestled within the forest where darkness reigns supreme. Places beyond the touch of the sun, beyond the influence of seasons. Here time is measured not in cycles of light but by the flow of water and fall of rock. These are the caves, conduits for water past and present. Nestled in the hills of south-central Kentucky the caves along Buck Creek provide the lifeblood for a …

A Hidden Markov Model Capable Of Predicting And Discriminating Β-Barrel Outer Membrane Proteins, Pantelis G. Bagos, Theodore D. Liakopoulos, Ioannis C. Spyropoulos, Stavros J. Hamodrakas

Pantelis Bagos

BACKGROUND: Integral membrane proteins constitute about 20-30% of all proteins in the fully sequenced genomes. They come in two structural classes, the alpha-helical and the beta-barrel membrane proteins, demonstrating different physicochemical characteristics, structure and localization. While transmembrane segment prediction for the alpha-helical integral membrane proteins appears to be an easy task nowadays, the same is much more difficult for the beta-barrel membrane proteins. We developed a method, based on a Hidden Markov Model, capable of predicting the transmembrane beta-strands of the outer membrane proteins of gram-negative bacteria, and discriminating those from water-soluble proteins in large datasets. The model is trained …
