Lipid liquid-crystalline nanoparticles as a suitable platform for accommodating sensitive membrane proteins: monitoring the activity of HMG-CoA reductase
No full textThis dataset contains experimental data related to the encapsulation of the transmembrane enzyme HMG-CoA reductase (HMGR) in liquid-crystalline lipid nanoparticles (hexosomes). The study aimed to optimize the composition and structure of the lipid nanocarriers to meet the requirements of this sensitive membrane protein and to compare its catalytic activity with that of the enzyme solubilized in aqueous solution. The dataset includes physicochemical characterization of the nanoparticles using DLS, SAXS, and cryo-TEM, as well as enzyme activity measurements via cyclic voltammetry (CV) and UV-Vis spectrophotometry. The catalytic function of HMGR was preserved within the hexosomes, as evidenced by NADPH consumption during the reaction. Additionally, data from inhibition experiments with the cholesterol-lowering drug fluvastatin are included.</p

Data sources for article: Photoluminescence efficiency of MBE-grown MoSe2 monolayers featuring narrow excitonic lines and diverse grain structures
No full textThis data was used as a foundation for the article by Mateusz Raczyński, Julia Kucharek, Kacper Oreszczuk, Aleksander Rodek, Tomasz Kazimierczuk, Rafał Bożek, Takashi Taniguchi, Kenji Watanabe, Wojciech Pacuski, and Piotr Kossacki. That was published in Journal of Luminescence.The archive contains the data used for the creation of all figures presented in the publication.Fig. 1 consists of four AFM measured height maps 800nm by 800nm in size. It is saved in a .gwy format used by a popular SPM visualisation and analysis software, 'Gwyddion'. The filenames are associated with subsequent MBE-grown sample names that were investigated UW1514, UW1870, UW1876, UW1930.Fig. 2 are the ASCII-coded plots. The left panel presents the photoluminescence spectra of five different samples. The x-axis is in units of energy (meV) and the y-axis is accordingly the PL intensity in 'spectrometer counts'. The right panel consists of the Raman scattering spectra in (arb.u.), and x-axis in units of inverse centimetres (cm^-1). The comment in the header indicates a particular MBE-grown sample and the hBN flake number noted as fxx, where xx is an arbitrary number-letter marking used during the measurements. The plots in Fig.2. were normalised and vertically offset for better comparison. The PL was in linear scale and Raman was in log-scale.Fig. 3 are the same plots like in Fig.2. but with all linear y-scale, the left one presents Raman spectra and the right the PL spectra, in the comment part of the header, the name of the appropriate hBN flakes (fxx) and their (hBNs) thickness in nanometers is provided. All these measurements were performed on the sample UW1870.Fig. 4 contains two measured and two calculated reflectance spectra for hBN of thicknesses 13.5nm and 491nm, respectively. The x-axis is in nanometers, the y-axis is unitless, because it is the measured(calculated) reflectance from the structure MoSe2/hBN/SiO2/Si divided by the reference of reflectance from just SiO2/Si.Fig. 5 consists of experimental data points, i.e., integrated PL and Raman intensities and the AFM-measured thicknesses of appropriate hBN flakes - presented as the scattered plots - and - the model-calculated PL/Ramans enhancement for a range of hBN thicknesses - that were presented on graphs as the dashed lines. The model is described in the manuscript, and it is simply based on a popularly used TMM (transfer matrix method). The experimental data is also described with the names of hBN spots at which the measurement took place. The sample being measured here was UW1870.Fig. 6 shows two plots. The left one presents the PL and Raman intrinsic brightnesses normalised by the one measured reference exfoliated sample. Therefore, the y-axis is relative in (%) and the x-axis is the monolayer (ML) coverage (in units of % too) read from the data presented in Fig.1. The right-hand side plot is the linewidth obtained from the fitted spectra for the charged and neutral excitons in units of (meV) vs the same x-axis - ML coverage (%).Fig. 7 is the graph presenting the same data as the one in Fig. 6a, but in the form of PL intensity vs Raman intensity. The ML coverage is the label for all five points for easier related sample identification. The fifth point relates to the newest sample, UW2156, not yet presented in previous graphs (ML coverage of 38%).Fig. 8 consists of two PL spectra in the same format as Fig. 2. Still, the y-axis has been modified to account for the different partial ML coverage and interference enhancement/suppression factors and to compare the PL efficiency of those two samples, UW1514 (ML coverage 27%) and UW2156 (ML coverage 38%). The x-axis is in energy units of (meV).Fig. 9 is the AFM height map of the sample UW2156 (ML coverage 38%) in the same format as Fig. 1.</p

Multidimensional analysis of Eurolect (Eurolect MDA)
No full textThe study applies full Multidimensional Analysis (MDA) to examine linguistic variation in the Polish Eurolect — a hybrid variety shaped by translation and institutional constraints within the European Union — by comparing it to the national variety, using a corpus of key institutional registers (legal acts, judgments, administrative reports, and citizen-oriented websites).The dataset includes:the corpora used in the study, encompassing four subcorpora of EU Polish registers and the subcorpora of corresponding domestic registers — legal acts, judgments, reports and websites. They were designed using a consistent sampling framework covering a five-year period, from 2011 to 2015. In this study each register is represented by two corpora: the EU Polish corpus, which contains translations into Polish (marked as EU), and the reference corpus of domestic non-translated texts (marked as PL). The corpora of EU legal acts and of EU judgments are further divided into two more narrowly defined text categories: regulations and directives, and judgements of Court of Justice and General Court, respectively. Please consult the readme.txt file for additional information.spreadsheets with 1) values obtained in the study; 2) description of variables used in the study.</ul
Zachowania zakupowe przed, w trakcie i po pandemii COVID-19
No full textZbiór zawiera wyniki ankiety przeprowadzonej metodą CATI na reprezentatywnej próbie 1010 dorosłych respondentów z Polski w maju i czerwcu 2022 roku. Pytania dotyczyły zachowań zakupowych online i offline przed, w trakcie i po pandemii i zostały zebrane na potrzeby projektu "Zakupy w sieci w czasach pandemii: wpływu pandemii COVID-19 na zachowania zakupowe Polaków w wymiarze społecznym i przestrzennym".Celem projektu było określenie specyfiki zmian zachowań zakupowych Polaków wywołanych przez pandemię w zakresie substytucji zakupowej. W szczególności projekt miał na celu określenie skali i trwałości oraz powodów zjawiska substytucji zakupowej: (a) w czterech kategoriach produktów (żywność paczkowana sucha, artykuły higieniczne i chemia gospodarcza, sprzęt RTV/AGD, ubrania) (b) w różnych grupach społeczno-demograficznych (wiek, płeć, wykształcenie, zachowania zakupowe przed pandemią, postrzegane ryzyko związane z płatnościami online, użytkowanie samochodu, posiadanie dzieci), (c) w różnych obszarach (miasta różnej wielkości/obszary wiejskie, obszary o różnej dostępności sklepów stacjonarnych, paczkomatów i punktów odbioru zakupów zrobionych w internecie). Badanie zrealizowane zostało na połączonej próbie telefonów stacjonarnych (20%) i komórkowych (80%), losowanych ze specjalnej bazy numerów wygenerowanych na podstawie zakresów numerów przydzielanych poszczególnym operatorom telekomunikacyjnym (stacjonarnym i komórkowym) przez Urząd Komunikacji Elektronicznej. Dzięki temu baza zawierała numery wszystkich telefonów, bez względu na fakt czy zostały one kiedykolwiek opublikowane w książce telefonicznej. Baza umożliwia praktyczne stosowanie metodologii losowego doboru numerów telefonów (Random Digit Dialing – RDD), pozwalającej dotrzeć do wszystkich aktywnych telefonów, bez względu na ich lokalizację terytorialną w kraju, w mieście czy na wsi. Losowanie numerów stacjonarnych odbywało się zgodnie z przyjętym warstwowaniem odpowiadającym podziałowi próby ogólnopolskiej na poszczególne województwa (16) i klasy wielkości miejscowości. Lokalizacja telefonów stacjonarnych (w podziale na gminy) jest w większości przypadków znana z góry, a w przypadkach wątpliwych jest potwierdzana w trakcie wywiadu. W ramach każdego gospodarstwa domowego dobierany był losowo respondent – przy czym procedura doboru uwzględniała nie tylko jego płeć i wiek, ale i wykształcenie. Telefony komórkowe losowane były jako prosta próba losowa dostępnych spośród całej puli numerów telefonów komórkowych. Lokalizacja terytorialna telefonów komórkowych była ustalana w trakcie wywiadu, a respondentem był posiadacz telefonu. Proporcje w liczbie wywiadów realizowanych w poszczególnych warstwach terytorialnych odpowiadają proporcjom populacji osób w wieku ponad 18 lat – dzięki czemu zapewnione jest dokładne pokrycie całego kraju badaniem, a – nawet niewielkie – różnice w stopniu telefonizacji kraju nie maja wpływu na reprezentatywność regionalną i urbanizacyjną zrealizowanej próby. </p
