Configurations of Europe

2006

This book has sought to gender men in Europe by drawing on various sources of information and in relation to key themes and policy arenas. In this final chapter, we consider some broad issues concerning the position and impact of men in the context of changing configurations of Europe, including, but not only, in relation to the EU. There are many ways in which the more explicit gendering of men raises new sets of questions about the EU and the changing definitions of ‘Europe’.

The maximum carbonyl ratio (MCR) as a new index for the structural classification of secondary organic aerosol components

2021

RATIONALE Organic aerosols (OA) account for a large fraction of atmospheric fine particulate matter and thus are affecting climate and public health. Elucidation of the chemical composition of OA is the key for addressing the role of ambient fine particles at the atmosphere-biosphere interface and mass spectrometry is the main method to achieve this goal. METHODS High-resolution mass spectrometry (HRMS) is on its way to becoming one of the most prominent analytical techniques, also for the analysis of atmospheric aerosols. The combination of high mass resolution and accurate mass determination allows the elemental compositions of numerous compounds to be easily elucidated. Here a new parame…

Soil fungi invest into asexual sporulation under resource scarcity, but trait spaces of individual isolates are unique

2022

During the last few decades, a plethora of sequencing studies provided insight into fungal community composition under various environmental conditions. Still, the mechanisms of species assembly and fungal spread in soil remain largely unknown. While mycelial growth patterns are studied extensively, the abundant formation of asexual spores is often overlooked, though representing a substantial part of the fungal life cycle relevant for survival and dispersal. Here, we explore asexual sporulation (spore abundance, size and shape) in 32 co-occurring soil fungal isolates under varying resource conditions, to answer the question whether resource limitation triggers or inhibits fungal investment…

From Feynman–Kac formulae to numerical stochastic homogenization in electrical impedance tomography

2016

In this paper, we use the theory of symmetric Dirichlet forms to derive Feynman–Kac formulae for the forward problem of electrical impedance tomography with possibly anisotropic, merely measurable conductivities corresponding to different electrode models on bounded Lipschitz domains. Subsequently, we employ these Feynman–Kac formulae to rigorously justify stochastic homogenization in the case of a stochastic boundary value problem arising from an inverse anomaly detection problem. Motivated by this theoretical result, we prove an estimate for the speed of convergence of the projected mean-square displacement of the underlying process which may serve as the theoretical foundation for the de…

Solid-state mechanochemical synthesis of multinary metal halide semiconductors for optoelectronics: From powder to thin film

2020

En la última década, las perovskitas de haluro de plomo, así como otros haluros de metales múltiples, incluidas las alternativas sin plomo, han demostrado ser materiales prometedores para su uso en optoelectrónica. Por lo tanto, se buscan activamente nuevas formas de producir semiconductores de alta pureza a gran escala. Por tanto, el objetivo principal de esta tesis doctoral es el desarrollo de perovskitas y semiconductores relacionados utilizando métodos sin disolventes. Además, con la perspectiva del uso de dichos materiales en optoelectrónica a escala industrial, el foco está puesto en trabajar con materiales benignos para el desarrollo de alternativas a las perovskitas tóxicas. La sínt…

Latvijas Universitātes Botāniskais dārzs

2007

Latvijas Universitātes paspārnē devīto gadu desmitu zaļo vecākais botāniskais dārzs Latvijā. Dārza 15 hektāru lielā teritorija ir daļa no Rīgas zaļās rotas ar kultūrvēsturisku vērtību. Tajā ir saglabājušās vairākas 18.–19. gadsimta ēkas – valsts nozīmes koka arhitektūras pieminekļi. Dārza kolekcijās ir augu sugas un to kultūrformas gan no Latvijas, gan no dažādām eksotiskām zemeslodes malām.

Chemical Composition and antimicrobial activity of the essential oils from two species of Thimus growing wild in southern Italy

2009

The volatile constituents of the aerial parts of two samples of Thymus longicaulis C. Presl, collected in Campania and in Sicily, and two samples of Thymus pulegioides L. from the same regions, were extracted by hydrodistillation and analyzed. Considering the four oils together, seventy-eight different compounds were identified: 57 for Thymus longicaulis from Sicily (91.1% of the total oil), 40 for Thymus longicaulis from Campania (91.5% of the oil), 39 for Thymus pulegioides from Sicily (92.5% of the oil) and 29 for Thymus pulegioides from Campania (90.1% of the oil). The composition of the oils is different, although the most abundant components are identical in T. pulegioides. The essent…
