The survey by foot in the field is compared to the survey from a car, the photo-interpretation of Google Street View (GSV) panoramas continuously and at intervals of 1.5 km and the photo-interpretation of Google Earth aerial images on a 10 km stretch of road in Sicily. The survey by foot was used as reference for the other methods. The interpretation of continuous GSV panoramas gave similar results as the assessment by car in terms of the number of species identified and their location, but with lower cost. The interpretation online of aerial photos allowed the identification of a limited number of taxa, but gave a good localisation for them. Interpretation of GSV panoramas, each of 1.5 km,…

L´on faict sçavoir que l´on vendra. El anuncio y catálogo impreso de la subasta de pinturas del Príncipe de Portugal (Bruselas, 1670)

2018

ABSTRACT: In 1670, in Brussels, a printed advertisement announced the auction of a valuable set of a hundred paintings, property of the late Fernando Alejandro de Portugal. A printed broadside announced the sale, and included the names of the artists and titles of the works, as well as their formats and the material form of the pieces, in some cases. Therefore, the advertisement is also an auction catalogue, one of the first to be printed in early modern Europe. This article seeks to tell the story of the print history of the humble broadside as advertisement and catalogue, as well as its content and information on the owners of this extraordinary collection of paintings.

Traffic-related pollutants in roadside soils of different countries in Europe and Asia

2015

We investigated the magnetic and chemical properties of the roadside soil samples collected from five European and Asian countries. Spots in which cars slowed down and/or accelerated due to the traffic organization (speed limits, junctions, and traffic lights) were selected for sampling. Apart from the Zabrze site (Poland), the magnetic susceptibility and heavy metal contents decreased with increasing distance from the road edge. The highest mass-specific magnetic susceptibility values (χ) were observed in the samples collected from Mumbai (India) and Zabrze (Poland). Moreover, the high contents of Fe, Ni, Mn, and Co were observed in Mumbai, whereas in Zabrze, all the examined elements demo…

Effect of deicing salts on urban soils and health status of roadside trees in the Opole region.

2004

This article reports on a study whose aim was to evaluate the impact of snow removal salts on urban soil properties and the health of roadside trees. The evaluation was done by chemical analyses of soil samples and plant matter combined with toxicity testing, performed with a Protoxkit F, a protozoan microbiotest. Samples were collected at 45 locations on three main roads in the town of Opole (Poland). The roads differed in the snow removal technology and amount of chemical substances (mostly NaCI) used on them during the winter. The study showed that when soil was exposed to a high level of NaCI, it tended to be more alkaline and also exhibited increased content of Na + and Cl - . The toxi…

Characteristics of current roadside pollution using test-monitoring plots

2014

Abstract The aim of the study was the qualitative recognition of the existing roadside pollutants deposited in topsoils located close to roads with high traffic volume. So far, the studies have helped to determine the content of pollutants that accumulated over a long period of time. Traditionally, it has been difficult to distinguish between roadside pollution and pollution from other industrial sources. In order to avoid such problems and to accurately recognize present threats originating from road traffic, test-monitoring plots were installed in Poland (Gliwice and Opole), Germany (Tubingen, Ulm and Boblingen), Finland (Helsinki), Tajikistan (Dushanbe) and China (Lanzhou). To install th…

Assessing the environmental impact exerted by roads in “operative” conditions - a Highway case-study

The subject of the study is analyzing the impact of coconut fibre and salt mixture used for eliminating slipperiness on roads on roadside soil. The tests were done on the soil samples taken from the fixed areas twice: in the autumn before applying the composite and in the following spring. Laboratory tests indicated decrease of conduciveness in soil after using the composite in wintertime. This can cause decreasing saltiness of roadside soil. In contrast to commonly used methods of eliminating slipperiness on roads with salts only applying the composite could diminish the negative effects of roadside soil saltiness.
