Trifolium – nieformalne porozumienie senatorów koronnych z lat trzydziestych XVII w
2020
Część historyków kwestionuje polityczne znaczenie trifolium — trójlistnej koniczyny, nieformalnego porozumienia senatorów koronnych, w którego skład wchodzili: kanclerz Jakub Zadzik, biskup chełmiński, hetman Stanisław Koniecpolski i Stanisław Lubomirski, wojewoda ruski. W latach 1631–1632 trifolium z powodzeniem popierało uposażenie członków rodziny królewskiej w Rzeczypospolitej, ale z powodu opozycji przedstawicieli Wielkiego Księstwa Litewskiego nie udało się przeprowadzić reformy elekcji. Podczas bezkrólewia w 1632 r. trifolium skutecznie sprzeciwiało się osłabieniu pozycji króla i senatu na rzecz izby poselskiej. W 1632 r. trifolium poparło wybór królewicza Władysława Wazy na tron pol…
Estimation of key biophysical parameters related to crop stress through new remote sensors and multi-crop in situ data
2020
El monitoreo de los cultivos a lo largo de toda la etapa de crecimiento es esencial para detectar anomalías y optimizar los costes y recursos del sector agrícola. Las variables biofísicas de la vegetación, principalmente el contenido en agua, el índice de área foliar o la clorofila, están consideradas indicadores importantes de la salud, crecimiento y productividad de la vegetación. Además, estos parámetros biofísicos no solo son importantes por proporcionar información por sí mismos del estado fisiológico de la vegetación, también porque son parámetros clave de entrada en importantes modelos agronómicos. La medida directa de estos parámetros biofísicos sobre el terreno requiere elevados re…
Distinctive Lexical Patterns in Russian Patient Information Leaflets: A Corpus-Driven Study
2019
This methodologically-oriented corpus-driven study focuses on distinctive patterns of language use in a specialized text type, namely Russian patient information leaflets. The study’s main goal is to identify keywords and recurrent sequences of words that account for the leaflets’ formulaicity, and - as a secondary goal - to describe their discoursal functions. The keywords were identified using three methods (G2, Hedges’ g and Neozeta) and the overlap between the three metrics was explored. The overlapping keywords were qualitatively analyzed in terms of discoursal functions. As for the distinctive multi-word patterns, we focused on recurrent n-grams with the largest coverage in the corpus…
De novo Transcriptome Assembly and Comparison of C3, C3-C4, and C4 Species of Tribe Salsoleae (Chenopodiaceae)
2017
C4 photosynthesis is a carbon-concentrating mechanism that evolved independently more than 60 times in a wide range of angiosperm lineages. Among other alterations, the evolution of C4 from ancestral C3 photosynthesis requires changes in the expression of a vast number of genes. Differential gene expression analyses between closely related C3 and C4 species have significantly increased our understanding of C4 functioning and evolution. In Chenopodiaceae, a family that is rich in C4 origins and photosynthetic types, the anatomy, physiology and phylogeny of C4, C2, and C3 species of Salsoleae has been studied in great detail, which facilitated the choice of six samples of five representative …

Physiological and Structural Responses to Prolonged Water Deficit in Young Trees of Two Olive Cultivars
2022
This study aimed to characterize the physiological and structural responses of potted one-year-old olive trees belonging to two olive cultivars—‘Nocellara del Belice’ and ‘Cerasuola’—exposed to prolonged drought under greenhouse conditions. Two irrigation treatments based on evapotranspiration (ET) were imposed for 69 days, i.e., well-watered (WW, 100% ET) and drought-stressed (DS, 10–30% ET). Leaf stomatal conductance (gs), stem water potential (Ψstem), transpiration (E), photosynthetic capacity (Amax), water use efficiency (WUE), stem (Kstem) and root (Kroot) hydraulic conductance, trunk diameter variations (TDV), and leaf patch attenuated pre…

Global Estimation of Biophysical Variables from Google Earth Engine Platform
2018
This paper proposes a processing chain for the derivation of global Leaf Area Index (LAI), Fraction of Absorbed Photosynthetically Active Radiation (FAPAR), Fraction Vegetation Cover (FVC), and Canopy water content (CWC) maps from 15-years of MODIS data exploiting the capabilities of the Google Earth Engine (GEE) cloud platform. The retrieval chain is based on a hybrid method inverting the PROSAIL radiative transfer model (RTM) with Random forests (RF) regression. A major feature of this work is the implementation of a retrieval chain exploiting the GEE capabilities using global and climate data records (CDR) of both MODIS surface reflectance and LAI/FAPAR datasets allowing the global estim…
HYPERBLEND: SIMULATING SPECTRAL REFLECTANCE AND TRANSMITTANCE OF LEAF TISSUE WITH BLENDER
2022
Abstract. Remotely sensing vegetation condition and health hazards requires modeling the connection of plants’ biophysical and biochemical parameters to their spectral response. Even though many models exist already, the field suffers from lack of access to program code. In this study, we will assess the feasibility of open-source 3D-modeling and rendering software Blender in simulating hyperspectral reflectance and transmittance of leaf tissue to serve as a base for a more advanced large-scale simulator. This is the first phase of a larger HyperBlend project, which will provide a fully open-source, canopy scale leaf optical properties model for simulating remotely sensed hyperspectral imag…
