Oczyszczanie Gazów Odlotowych Ze Spalania Odpadów Niebezpiecznych, Robert Oleniacz

Robert Oleniacz

Flue gas cleaning system is a very important part of each hazardous waste incineration plant. Air pollutant emission limit values permissible for this process in Member States of the European Union are so rigorous that the installation designers there are forced to use very effective and of course expensive solutions. In the paper a review of methods and systems used to the treatment of flue gases from hazardous waste incineration is presented. This can be particularly useful in the face of the adaptation of existing waste incineration plant operating in Poland with European Union requirements.

English title: Cleaning of flue …

Acetate Oxidation Coupled To Fe(Iii) Reduction In Hyperthermophilic Microorganisms, Jason M. Tor, Kazem Kashefi, Derek Lovley

Derek Lovley

No hyperthermophilic microorganisms have previously been shown to anaerobically oxidize acetate, the key extracellular intermediate in the anaerobic oxidation of organic matter. Here we report that two hyperthermophiles, Ferroglobus placidus and “Geoglobus ahangari,” grow at 85°C by oxidizing acetate to carbon dioxide, with Fe(III) serving as the electron acceptor. These results demonstrate that acetate could potentially be metabolized within the hot microbial ecosystems in which hyperthermophiles predominate, rather than diffusing to cooler environments prior to degradation as has been previously proposed.

Reconsidering The Platonic Cleitophon, Kyriakos N. Demetriou

Kyriakos N. Demetriou

This article unravels the riddle of the Platonic "Cleitophon" through an examination of S.R. Slings' "Plato, Clitophon" (Cambridge University Press, 1999). It examines the history of the reception of this dialogue from the 19th century to present day Platonic analytic and interpretative approaches.

Constant Mean Curvature Surfaces With Three Ends, Karsten Grosse-Brauckmann, Robert Kusner, John M. Sullivan

Robert Kusner

We announce the classification of complete almost embedded surfaces of constant mean curvature, with three ends and genus zero. They are classified by triples of points on the sphere whose distances are the asymptotic necksizes of the three ends.

Optically Induced Periodic Structures In Smectic-C Liquid Crystals, Antal Jákli, A. Vajda, E. Benkler, Janossy, Peter Palffy-Muhoray

Antal Jakli

We explore periodic structures of smectic-C (SmC) liquid crystals, induced optically by a polarization grating. The studied cells contain a passive surface of rubbed polyimide and an active photosensitive substrate of ate-dye doped polyimide. In a nematic phase the director field can be periodic independent of the angle between the grating vector and the rubbing direction. In the SmA phase periodic structure can be induced only by layer undulations. The SmC behaves similarly to the nematic phase, but the director can rotate only on a cone, which results in a more complex geometry. The periodic pattern is superimposed with four …

Temporal Changes In The Observed Relationship Between Cloud Cover And Surface Air Temperature, Bomin Sun, Pavel Ya. Groisman, Raymond S. Bradley, Frank T. Keimig

Raymond S Bradley

The relationship between cloud cover and near-surface air temperature and its decadal changes are examined using the hourly synoptic data for the past four to six decades from five regions of the Northern Hemisphere: Canada, the United States, the former Soviet Union, China, and tropical islands of the western Pacific. The authors define the normalized cloud cover–surface air temperature relationship, NOCET or dT/dCL, as a temperature anomaly with a unit (one-tenth) deviation of total cloud cover from its average value. Then mean monthly NOCET time series (night- and daytime, separately) are area-averaged and parameterized as functions of surface air humidity …

The Fragmentation Of Self Within The Indian Novel, Michele Gibney

Michele Gibney

With the novel Midnight’s Children, Rushdie forged a new path for novel-writing. In his epic story the main character became split into two in order to show the many facets of Indian culture. Instead of gaining an understanding of just one way of life, the reader became privy to all the stories being lived in such places as the Methwold estates, the surreal Sundarbans, and the Magician’s Ghetto. The story of one, single individual was lost in the cacophony of voices that each had their own tale to tell in Rushdie’s novel. This new form of writing, which favored the …

The Northeast Asian Seas: The Regional Legal Instruments Of Cooperation For Marine Environment And Sustainable Development, Young K. Kim

Young K Kim

The Asia Pacific region is characterized by a number of features which give prominence and unique significance in relation with the marine environment issues. As a result of rapid growth in population, economy, and political maturity, marine environment protection and resource management have emerged as a vital task for the individual nations, as well as the Asia Pacific region as a whole. The concerned riparian States of the Northeast Asian Seas have been fully aware of the immediate relevance of the target conception, "the sustainable development" for their economic development and environment policy. Since 1992 Rio UNCED, they have endeavored …

Should Courts Deduct Non-Legal Sanctions From Damages?, Robert D. Cooter, Ariel Porat

Robert Cooter

When legal and social norms regulate the same behavior, an act can trigger both legal and non-legal sanctions. Should courts deduct the non-legal sanction suffered by the wrongdoer from damages owed to the victim? We provide the answer for a legal system that seeks to minimize social costs. Non-legal sanctions typically harm the wrongdoer and benefit other people. In principle, courts should avoid over-deterring wrongdoers by deducting the benefit of the non-legal sanction from compensatory damages. In practice, instead of deducting the benefit of the non-legal sanction to other people, courts should deduct the burden on the wrongdoer. Deducting the …

The Two Koreas: Prospects For Economic Cooperation And Integration, Marcus Noland

Marcus Noland

After nearly a half century of strident adherence to the principles of socialism and self-reliance, North Korea may be on the verge of opening itself to outside aid and advice. Motivators include a decade of economic trouble punctuated by declining output and famine as well as underdeveloped infrastructures and reduction in foreign trade and material support. The limits of national selfsufficiency may finally have become admissible in North Korea, as evidenced by recent diplomatic negotiations and cooperative commercial projects with capitalist nations. South Korea, meanwhile, is struggling to regain ground lost in the financial crisis and to correct faults in …

Real Time And Relative Indeterminacy In Economic Theory, Mario Rizzo

Mario Rizzo

Extension Workers As Orchestrators Of Civic Renewal Through Civic Professionalism, Nancy K. Franz

Nancy K. Franz

I have a passion and a bias. I am passionate about the important role of the Cooperative Extension System (CES) in civic renewal. My bias is that extension workers (also known as agents or educators) are the key to civic renewal throughout the United States. No other institution has the same ability to reach all of America with education and organizing efforts. With extension workers in every county in the nation, this group of professionals and their work cut across age, race, ethnicity, religion, geography and many other demographic characteristics. Extension has a long history of being active in civic …

Mean Annual Temperature Trends And Their Vertical Structure In The Tropical Andes, Mathias Yuille, Raymond S. Bradley

Raymond S Bradley

Mean annual temperature trends in the tropical Andes were determined over the last six decades ( 1939-1998), to investigate the apparent inconsistency between the observed glacier retreat and the reported slight cooling trend in the lower tropical troposphere after 1979. Our results indicate that temperature in the tropical Andes has increased by 0. 10° - 0. I l °C/decade since 1939. The rate of warming has more than tripled over the last 25 years (0.32° - 0.34 °C/decade) and the last two years of the series, associated with the 1997/98 El Nino, were the warmest of the last six decades. …

A Review Of Shellfish Restoration As A Tool For Coastal Water Quality Management., Michael A. Rice

Michael A Rice

In many areas, coastal residents and others oppose establishment of bivalve molluscan aquaculture projects on the basis of perceived negative environmental impacts. Often overlooked are positive environmental impacts of shellfish aquaculture that can potentially mitigate the impacts of other anthropogenic activities. Filter feeding by populations of bivalve mollusks is reviewed with respect to their ability to act as an estuarine filter, increase clarity of coastal waters and facilitate the removal of nitrogen and other nutrients from eutrophic coastal waters. Most species of cultured bivalve mollusks clear particles from waters at rates of 1 to 4 L/h, and populations of shellfish …

Truth-Bonding And Other Truth-Revealing Mechanisms For Courts, Robert Cooter, Winand Emons

Robert Cooter

In trials witnesses often gain by slanting their testimony. The law tries to elicit the truth from witnesses by cross-examination under threat of criminal prosecution for perjury. As a truth-revealing mechanism, perjury law is crude and ineffective. We develop the mathematical form of a perfect truth-revealing mechanism, which exactly offsets the gain from slanted testimony by the risk of a possible sanction. Implementing an effective truth-revealing mechanism requires a witness to certify accuracy by posting bond. If events subsequently prove that the testimony was inaccurate, the witness forfeits the bond. By providing superior incentives for telling the truth, truth-bonding could …

PURPOSE OF STUDY To document the peak stages of flood flow of Hurricane Mitch in a tropical rain forest river, and their relation to channel morphology. These flood stages were the highest of the century on this river according to indigenous people living along the river bank.

A Feminist ‘Attack’ On Post-Structuralist And Psychoanalytical Readings Of Hamlet, Michele Gibney

Michele Gibney

This paper will do three things, the first of which will be to describe Jaqueline Rose’s argument within her essay, “Hamlet—The Mona Lisa of Literature.” The second task of this paper will be to explain what is at stake within Rose’s essay as it relates to previous criticism such as that of Irigaray, Freud, Woolf, and Derrida. Finally, by drawing upon the idea (in Rose’s paper) of femininity as a fetishisized concept that equals the opposite of “good” a correlation in opposition will be drawn between what she is trying to accomplish and what Freud argues in “The Theme of …

Covert Shells, John Christian Smith

John Christian Smith

The potential for covert communications exist anywhere that legitimate communication channels are in use. In order to maintain control of the channel once exploited, the insertion of a backdoor Trojan horse server, to be used with a client that provides shell access, is often a necessary prerequisite to establishing and using a covert channel long term.

We discuss covert channel communications methods ranging from embedded channels to disguised protocols. What follows is a review of available covert shell tools. The underground, historical evolution of covert shells is reviewed, focusing on selected, available tools, which range from simple encapsulation methods to …

Gis And Spatial Analysis In Urban And Regional Research, Derek Bond

Derek Bond

The early optimism surrounding GIS has now faded. Few GIS implementations have lived up to expectation. The most successful have been those at the operational level where their main role has been to replace paper maps with digital ones. However, as the cost of GIS implementation falls and spatial data becomes more readily available there is a need to consider the future of GIS and spatial analysis. This is particularly important in the field of urban and regional research especially where considerable investment in GIS has already been made. This paper looks at the major issues that face regional and …

Development Of Real-Time Pcr Assays For Rapid Detection Of Pfiesteria Piscicida And Related Dinoflagellates, Torstein Tengs

Dr. Torstein Tengs

Pfiesteria complex species are heterotrophic and mixotrophic dinoflagellates that have been recognized as harmful algal bloom species associated with adverse fish and human health effects along the East Coast of North America, particularly in its largest (Chesapeake Bay in Maryland) and second largest (Albermarle- Pamlico Sound in North Carolina) estuaries. In response to impacts on human health and the economy, monitoring programs to detect the organism have been implemented in affected areas. However, until recently, specific identification of the two toxic species known thus far, Pfiesteria piscicida and P. shumwayae (sp. nov.), required scanning electron microscopy (SEM). SEM is a …

Temperature-Induced Configurational Excitations For Predicting Thermodynamic And Mechanical Properties Of Alloys, Duane D. Johnson, Andrei V. Smirnov, J. B. Staunton, F. J. Pinski, W. A. Shelton

Duane D. Johnson

We show that a structural energy difference, ΔE, must include explicit symmetry-breaking changes of the electronic structure due to temperature-induced configurational excitations, and why ΔE at T=0 K is not necessarily relevant to thermodynamic and mechanical modeling. In Ni3V, we calculate a tenfold decrease of ΔE between D022 and L12 structures from T=0 K to states of order relevant to experiment. ΔE calculated directly from states with short-range order (8 meV) or with low partial order (7–12 meV) agree with high-T experiment (10 meV).
