Badania Emisji Chlorowodoru I Związków Fluoru Podczas Spalania Odpadów Niebezpiecznych, Marian Mazur, Robert Oleniacz, Marek Bogacki

Robert Oleniacz

The paper presents the results of measurements of the concentration of hydrogen chloride (HCl) and fluoride compounds (as HF) in raw and purified combustion gases discharged from the incineration of selected hazardous wastes. The study included two installations operating on an industrial scale: a multiple hearth furnace and a rotary kiln incinerator equipped with a single wet flue gas cleaning systems. In the multiple hearth furnace was being incinerated sludge from coke industry. In the rotary kiln were being incinerated coal (coke) tars, contaminated cleaning rags, sawdust, used gloves, outdated pharmaceuticals and medicines, hospital waste, waste paints, varnish and lubricant, …

Emisja Zanieczyszczeń Ze Spalania Odpadów Farmaceutycznych I Poszpitalnych W Piecu Obrotowym, Robert Oleniacz, Marian Mazur, Marek Bogacki

Robert Oleniacz

The work presents the problem of management and thermal treatment of medicines and hospital wastes and investigation results of incineration of these waste in the full-scale rotary kiln with wet gas cleaning equipment (alkaline scrubber). On the basis of measurements of air pollutant concentrations in combustion gases, maximum dose of these wastes in the feed to the kiln was specified in order to ensure a relatively low stack emissions using the hypothetical high-efficiency flue-gas treatment system.

English title: Pollutant emissions from incineration of pharmaceutical and hospital waste in a rotary kiln.

Equatorial Wind Compression Effects Across The H-R Diagram., R. Ignace, J. P. Cassinelli

Richard Ignace

We investigate the degree to which moderate stellar rotation rates can influence the two-dimensional density structure in the winds of four classes of stars: WoIf-Rayet, B[e], asymptotic giant branch (AGB), and novae. These classes are distributed across the H-R diagram and have a wide range of escape speeds and wind acceleration. Furthermore, all have members which possess asymmetric circumstellar nebulae. It has been suggested that these asymmetries could result from stellar winds which have moderate equatorial density enhancements. Large enhancements may arise as the result of stellar rotation as demonstrated by the wind-compressed disk (WCD) model of Bjorkman & Cassinelli. …

In-Situ Imaging Of Ionic Crystal Dissolution Using An Integrated Electrochemical/Afm Probe, Julie V. Macpherson, Patrick R. Unwin, Andrew C. Hillier, Allen J. Bard

Andrew C. Hillier

The kinetics and mechanism controlling dissolution from the (100) cleavage face of potassium bromide single crystals in acetonitrile solutions have been identified using a novel integrated electrochemical/AFM probe and a scanning electrochemical microscope (SECM). With both techniques, dissolution is induced by perturbing the dynamic dissolution/growth equilibrium at the crystal/solution interface through the electrochemical oxidation of bromide ions. SECM measurements demonstrate that the dissolution reaction is diffusion-limited under the experimental conditions, suggesting that the surface reaction is characterized by a rate constant in excess of 5 cm s-1 (assuming a first-order dissolution process). The topography of the dissolving surface has been …

Testing For Absolute Purchaing Power Parity, Douglas G. Steigerwald, Collin Crownover, John Pippenger

Douglas G. Steigerwald

Purchasing power parity (PPP) is an equilibrium condition equating the nominal exchange rate between two countries with the relative price of an identical bundle of goods in each country. Previous time-series researchers use price indicies to study PPP, so they study relative PPP. We use new data that measures price levels, so we test absolute PPP. Price levels provide a test of absolute PPP because, unlike price indicies, do not contain a base period in which the nominal exchange rate equals the price ratio by construction. We find support for absolute PPP.

Measurement Of Double-Layer Forces At The Electrode/Electrolyte Interface Using The Atomic Force Microscope: Potential And Anion Dependent Interactions, Andrew C. Hillier, Sunghyun Kim, Allen J. Bard

Andrew C. Hillier

The forces between a silica probe and silica and gold substrates were measured with an atomic force microscope in the presence of a series of alkali-halide electrolyte solutions. The interaction between two silica surfaces was repulsive and could be accurately predicted by Derjaguin-Landau-Verwey-Overbeek theory. The silica surface was negatively charged at a pH of 5.5 and the effective surface potential increased in magnitude with decreasing electrolyte concentration. In contrast, the force between the silica probe and a gold substrate was attractive at open circuit. This interaction was a strong function of the potential applied to the gold and the nature …

A Control Basis For Multilegged Walking, Manfred Huber, Willard S. Macdonald, Roderic Grupen

Roderic Grupen

This paper presents a distributed control approach to legged locomotion that constructs behavior on-line by activating combinations of reusable feedback control laws drawn from a control basis. Sequences of such controller activations result in flexible aperiodic step sequences based on local sensory information. Different tasks are achieved by varying the composition functions over the same basis controllers, rather than by geometric planning of leg placements or the design of new task-specific behaviors. In addition, the device-independent nature of the control basis allows its generalization not only over task domains, but also over different hardware platforms. To show the applicability of …

An Augmented Galerkin Algorithms For First Kind Integral Equations Of Hammerstein Type, S. Abbasbandy, E. Babolian

Saeid Abbasbandy

Recent papers, [1],[2] & [3], describe some algorithms for linear first kind integral equations. These algorithms are based on augmented Galerkin method and Cross-validation scheme [5]. The results show that, these algorithms work well for linear equations. In this paper we apply algorithms of [1] & [2] on non-linear first kind integral equations of Hammerstein type with bounded solution. In order to obtain a posteriori error estimate, we apply fifteen-point Gauss-Kronrod quadrature rule [4]. Finally, we give a number of numerical examples showing that the algorithms work well in practice.

Purchasing Power Parity, Unit Roots And Dynamic Structure, Douglas G. Steigerwald

Douglas G. Steigerwald

Recent studies of puchasing power parity (PPP) account for the possible presence of unit roots in nominal exchange rates and relative price indicies by applying standard unit-root tests to real exchange rates, which are ratios of nominal exchange rates and relative price indicies. These studies occasionally find evidence of PPP but, as a whole, the evidence is not definitive. Standard unit-root tests impose a restrictive dynamic structure between nominal exchange rates and relative price indicies. I specify and estimate a generalized dynamic structure. I reject the dynamic restrictions implicit in standard unit-root tests of PPP, and find stronger evidence of …
