Gdansk, Poland, 1886 (Raster Image)

This layer is a georeferenced raster image of the historic paper map entitled: Danzig. It was published by Geogr. Anstalt von Wagner & Debes in 1886. Scale 1:12,500. Covers Gdansk, Poland.The image inside the map neatline is georeferenced to the surface of the earth and fit to the 'Pulkovo 1942 Adjust 1958 Poland Zone III' coordinate system. All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map.This map shows features such as roads, railroads, drainage, canals, built-up areas and selected buildings, fortification, ground cover, and more. Relief shown by hachures.This layer is part of a selection of digitally scanned and georeferenced historic maps from The Harvard Map Collection as part of the Imaging the Urban Environment project. Maps selected for this project represent major urban areas and cities of the world, at various time periods. These maps typically portray both natural and manmade features at a large scale. The selection represents a range of regions, originators, ground condition dates, scales, and purposes.

Composition of bottom sediments and interstitial waters from the Gdansk Bay

Contents of mercury and zinc in reduced sediments and interstitial waters of the Gdansk Bay in the Baltic Sea were investigated. It was found that sediments contain 0.7 ppm Hg, of which 0.008 ppm.(0.4% of total) is dissolved in interstitial water, and 91 ppm Zn, of which 0.15 ppm (0.45% of total) is dissolved in interstitial water. Differences in contents in different layers (0-5 and 25-30 cm) can be attributed to anthropogenic influence. Aderage concentration of mercury in the upper sediment layer is 27% higher and one of zinc is 40% higher than those found in the lower sediment layer. In addition, distribution of zinc in grain size fractions of the sediments was investigated, and some data on cadmium content were obtained.

Virtual worlds as a model-view approach to the communication of business processes models

The improvement and optimization of business processes is one of the top priorities in an organization. Although process analysis methods are mature today, business analysts and stakeholders are still hampered by communication issues. That is, analysts cannot effectively obtain accurate business requirements from stakeholders, and stakeholders are often confused about analytic results offered by analysts. We argue that using a virtual world to model a business process can benefit communication activities. We believe that virtual worlds can be used as an efficient model-view approach, increasing the cognition of business requirements and analytic results, as well as the possibility of business plan validation. A healthcare case study is provided as an approach instance, illustrating how intuitive such an approach can be. As an exploration paper, we believe that this promising research can encourage people to investigate more research topics in the interdisciplinary area of information system, visualization and multi-user virtual worlds.
