This project investigates the correlation between contaminants and the wood waste present in marine sediments off the shore of the Port of Everett in the former Weyerhaeuser Mill-A pulp mill site. The investigation includes the results of two field studies, which tested contaminant levels in 22 boreholes as well as several surface samples. The contaminants include heavy metals and wood waste byproducts. These results, along with 14 other bore logs, provide the framework for a three-dimensional site model, interpolating the full extent of the depositional units and organic and inorganic chemicals found at Mill-A. The sediments of interest are divided into five depositional units defined by the percent wood content and type of wood: native material (<5% wood), intermediate (<30% wood), sawdust (<30% wood), woodchips (<30% wood), and poorly sorted sands with silt (SM-SP) (0% wood). The contaminants include arsenic, 2,4-dimethylphenol, and total organic carbon. Three-dimensional modeling software, RockWorks, interpolated the discrete borehole data of sediment and contaminants assuming horizontal continuity between sampling locations. The sediment distribution was calculated within concentration ranges for each contaminant of concern. The lowest detection limits, the screening levels, and the cleanup levels defined these ranges. Total organic carbon served as a proxy to estimate the quantity of wood waste in the sediment. As a known byproduct of wood decomposition, 2,4-dimethylphenol was expected to be more prevalent in the depositional units with more wood waste. Finally, arsenic was a proxy for other contaminants to determine if contaminants at Mill-A are dominant in sediments with high percentages of wood waste. The volumetric distribution established that high levels of total organic carbon are present in the sediment with higher percentages of wood waste. This correlation was stronger in the decomposing sawdust-rich sediment than the woodchip-rich sediment. The 2,4-dimethylphenol concentrations above cleanup standards were dominant in the sawdust-rich, intermediate and native sediments. Concentrations of 2,4-dimethylphenol below cleanup levels characterized the native sediment. The distribution of arsenic showed no statistically significant correlation to wood content in sediment. These results do not support the hypothesis of contaminant-rich wood waste, as many of the high concentrations of contaminants were not in the wood-rich sediments. This suggests that the contaminants are more distributed among all depositional units at Mill-A rather than focused within sediments with a high percent of wood waste. Understanding the distribution of potentially toxic compounds with wood waste is important for restoring the Puget Sound waterways to a more habitable environment. Future studies should include new data to validate these results and to limit the uncertainty of the extent of contaminants. Future studies may also find motive in looking for a correlation between contaminants and grain size based on previous studies linking these characteristics. These investigations will benefit the current cleanup effort as well as future cleanup efforts at similarly contaminated waterways.

The available literature has been surveyed to determine the parameters affecting fuelling requirements of spark ignition engines and their relation to engine performance and emissions. Theories and experiment relating to two phase and multi-component flows have also been examined and the techniques employed in the measurement of droplet sizes and liquid wall films have been reviewed. Following preliminary steady flow visualisation experiments to examine the trajectories of droplets discharging from the valve port an extensive practical investigation of the spectrum of droplet sizes formed by the break up of the wall film has produced results which have been correlated in terms of the important fuel and airflow parameters. It is concluded that the Sauter mean diameter of droplets formed by the break up of the wall film will vary between 70 and 150 m, depending on the operating conditions of the engine. The spectra of droplet sizes measured show that a significant proportion of the total mass of the wall film breaks into drops which will be too large to burn completely and, by comparison with measurements of unburned hydrocarbon emissions from engines supplied with a homogeneous mixture of air and gaseous hydrocarbons, it is concluded that the droplets from the wall film are likely to increase emissions by 50%.

Az utóbbi évtizedek nemzetközi trendjei azt mutatják, hogy a civil szervezetek és a nonprofit szolgáltatók számottevő hatást gyakorolnak a versenyképesség alakulására. Ez a tanulmány azokat a formális és informális mechanizmusokat tekinti át, amelyeken keresztül a civil társadalom befolyásolja a közintézményi döntéseket és azok gyakorlati megvalósítását, hozzájárul a „government”-tôl a „governance” irányába való elmozduláshoz. Szintén képet ad arról az átalakulási folyamatról, amely a közszolgáltatások területén zajlik, s amelyből egyre markánsabban rajzolódik ki a közösségi kezdeményezésen alapuló, társadalmi ellenőrzés alatt működő nonprofit szolgáltatók és az állami szereplők közötti partneri viszony kialakulásának tendenciája. ____________ The international trends of the last decades have revealed that civil society organisations and nonprofit service providers have a significant impact on competitiveness. This paper gives an overview of the formal and informal mechanisms operated by civil society in order to keep public administration accountable, to influence public decisions and their implementation, thus moving from “government” towards “governance”. It also analyses the transition of public services, the more and more noticeable signs of an emerging partnership between the grassroots, community controlled service providing nonprofit organisations and the government actors.

The objective of this article is to introduce the main blocks in building virtual front and back offices of public administration. Virtual administration is probably kind of an ultimate or top stage of ICT platforms of e-government. First a justification is given why 3D government fits in the recent EU directives of e-government development. The relevant scholarship contains a brief description of the visualized e-government, and then a fully illustrated, step by step survey reveals the itinerary to construct virtual government which is the main result of the study. The article concludes with a discussion on the practical benefit of such a research if there is one.
