Use of algae in active biomonitoring of Surface waters

2014

Przeprowadzono badania biomonitoringowe trzech zbiorników retencyjnych położonych na terenie województwa opolskiego (południowa Polska): Zbiornika Turawa, Zbiornika Nysa i Zbiornika Otmuchów. W glonach słodkowodnych Spirogyra sp. i morskich Palmaria palmata (Linnaeus) Weber & Mohr, eksponowanych w badanych wodach, oznaczono metodą absorpcyjnej spektrometrii atomowej (AAS) przyrosty stężeń: Mn, Fe, Cu, Zn, Cd i Pb. W wodach oznaczano także pH, konduktywność oraz stężenie Mn i Fe. Stężenia Cu, Zn, Cd i Pb w badanych wodach były mniejsze od granicy oznaczalności metody. Badania prowadzono od czerwca do lipca 2014 r. Wskazano na różnice w przyrostach stężeń metali ciężkich w próbkach glonów eks…

Automatic analyzis of droplet impact by high speed imaging

2012

International audience; The impact of agricultural activities on the water quality is the consequence of the loss of fertilisers (chemical fertilisers, livestock effluent, also referred to as farm fertiliser, food-processing effluent and sludge) and crop treatment products (phytosanitary products). This pollution may prevent certain uses of water, notably its use for human and animal food (groundwater and surface water), and leads to a deterioration in aquatic environments. In the domain of vineyard precision spraying research, one of the most important objectives is to minimize the volume of phytosanitary products. It is also to be more environmentally respectful with more effective vine l…

Formaciones sociales y opresión en Marx

2018

The text explains the difference between Marx?s concept of «oppression» and others as «coercion» by Durkheim or «domination» by Weber. The article then establishes, in a methodical way, the centrality of a passage from Capital, in which three different theories on «oppression» appear. It?s explained that two of them are rather a philosophical antinomy. The other, relative to the heteronomy of social time, can be completed by defining the heteronomy of social space, which gives it analytical virtuality. Some examples are given.

Politicisation of Travelling : Interrail and Freedom

2020

Travelling is today an important aspect of the European political agenda-setting of both individual actors and institutions. The paradigms of car and air travel are contested in terms of climate change; I continue the contestation from the perspective of political liberty. Three paradigms of personal travel – by car, by flight and by train – are confronted with two concepts of liberty: the freedom from interference versus the freedom from dependence. Three ideal types of travel – travelling to, travelling away and travelling around – are judged from the perspective of the two freedoms. Train travel by Interrail is a political innovation that links the freedom of movement to the freedom from…

A Lost Opportunity to Parliamentarize The European Commission : Bagehot, Weber and a Debate in 1960

2022

The article emphasizes the significance of EU studies for political thought and concepts. It deals with the seemingly technical topic of the membership of cabinet ministers in parliament. This practice arose in eighteenth-century Westminster and has been discussed since the mid-nineteenth century, Walter Bagehot's and Max Weber's writings being landmarks. When the European Parliamentary Assembly in 1960 interpreted the Treaty of Rome, it took the view, by a narrow margin, that membership of the Parliament was incompatible with membership of the Commission. The debate on the compatibility of dual membership could have been a way to promote the parliamentarization of the EU. peerReviewed

Behavioural thresholds of blue tit colour vision and the effect of background chromatic complexity

2020

Vision is a vital attribute to foraging, navigation, mate selection and social signalling in animals, which often have a very different colour perception in comparison to humans. For understanding how animal colour perception works, vision models provide the smallest colour difference that animals of a given species are assumed to detect. To determine the just-noticeable-difference, or JND, vision models use Weber fractions that set discrimination thresholds of a stimulus compared to its background. However, although vision models are widely used, they rely on assumptions of Weber fractions since the exact fractions are unknown for most species. Here, we test; i) which Weber fractions in lo…
