Methodology for the retrieval of vegetation chlorophyll fluorescence from space in the frame of the flex mission preparatory

2016

FLEX (FLuorescence EXperiment) is a candidate mission for the European Space Agency (ESA) Earth Explorer program. The main objective of the mission is the measurement the chlorophyll fluorescence signal emitted by vegetation at the red and far-red spectral regions (roughly 630-770 nm). The current FLEX mission design includes different instruments intended to provide the appropriate characterization of those atmospheric and surface parameters necessary for the retrieval and interpretation of the fluorescence signal. The complete processing chain for the derivation of fluorescence and reflectance products from the radiance data acquired by the different instruments included in the FLEX paylo…

Quantification of phenolic acids by partial least squares Fourier-transform infrared (PLS-FTIR) in extracts of medicinal plants.

2020

Introduction Phenolic compounds are ubiquitous compounds found in all plants as their secondary metabolites. Phenols are becoming increasingly important particularly because of their beneficial effects on health. Objective To provide a faithful calibration model for the simultaneous determination and quantification of phenolic acids, as salicylic, vanillic, p-hydroxybenzoic acids, eugenol and thymol in different extracts of medicinal plants, a comparative study was made between two methods of infrared measurements based on attenuated total reflectance (ATR) and transmission. Methods Characteristic absorbance peak heights of mid-infrared spectra of individual phenolic acids were measured for…

Mapováni spinů povrchových a bulkových Rashba stavů v tenkých vrstvách feroelektrického α-GeTe(111)

2015

Rozbíjení inverzní symetrie ve fereeleRashba efekt; Fotoemisse; DFTktrickém polovodiči způsobuje děleni stavů, tzv Rashba efekt. V tomto článku ukazujeme kompletně mapování spinové polarizace těchto Rashba stavů za pomoci spinovo rozlišené fotoemisse. The breaking of bulk inversion symmetry in ferroelectric semiconductors causes a Rashba-type spin splitting of electronic bulk bands. This is shown by a comprehensive mapping of the spin polarization of the electronic bands in ferroelectric α- GeTe(111) films using a time-of-flight momentum microscope equipped with an imaging spin filter that enables a simultaneous measurement of more than 10 000 data points. The experiment reveals an opposite…

Antoniego Zabłockiego relacja o pobycie Katarzyny II i Józefa II w Chersoniu i na Krymie w roku 1787

2022

From July 1784 to mid-1792, a Polish trade and diplomatic post operated in Kherson (until the spring of 1788), and then in Mirgorod, in the Black Sea territories of the Russian Empire. From mid-1784 until the end of 1791, Antoni Zabłocki, a former soldier of the Crown Army, the Bar Confederate, and an exile in Russia, was the head of the facility, and from the summer-autumn 1786, the consul. He did not have any diplomatic preparation, and his qualifications were limited to the knowledge of the Russian language and the realities of social and economic life in the tsarist state, as well as to close contacts with the surroundings of King Stanisław August. This secured him a job as a royal agen…

Academics as Politicians and as Operators of Global Governance

2018

In this chapter, the author scrutinizes the links between politics and academe in global governance. He analyzes two cases, those of former president of the European Commission Jose Manuel Barroso and philosopher Michel Foucault, that exemplify different types of political engagement. Social scientists play a key but concealed part in the steering of global governance. Under and beyond global institutions, they partake in the development of influential transnational professional groups. By producing practical knowledge for everyday or ‘banal’ global governance, social scientists shape the politically imaginable at more institutional levels. Yet others provide at a higher level of abstractio…

Conclusion: A Conversation

2017

In the concluding chapter the editors of the volume take a conversational look into the producing process of Nordic Girlhoods: New Perspectives and Outlooks. The authors discuss key contemporary issues and future perspectives in Nordic girlhood studies and foreground the political relevance of the research field in the contemporary societal situation. They call for reflexive and critical theorizations on what counts as the Nordic, especially when the girl is to be found in the middle of several nationalistic desires and conservative political discourses.

Bee reverse-learning behavior and intra-colony differences: Simulations based on behavioral experiments reveal benefits of diversity

2014

Abstract Foraging bees use color cues to help identify rewarding from unrewarding flowers. As environmental conditions change, bees may require behavioral flexibility to reverse their learnt preferences. Learning to discriminate perceptually similar colors takes bees a long time, and thus potentially poses a difficult task to reverse-learn. We trained free-flying honeybees to learn a fine color discrimination task that could only be resolved (with about 70% accuracy) following extended differential conditioning. The bees were then tested for their ability to reverse-learn this visual problem. Subsequent analyses potentially identified individual behavioral differences that could be broadly …
