title: The aggregation of objects representing Katowice district buildings - scale 1:25000

description: The process of automatic generalization is one of the elements of spatial data preparation for the purpose of creating digital cartographic studies. The presented data include a part of the process of generalization of building groups obtained from the national geodesy and cartography resource from BDOT10k (10k topographic database) [1].
The data include the spatial scope of Katowice district. In the district, there are buildings of almost every class according to the BDOT10k classification except BUBD20. Single-family residential buildings constitute 34% of all buildings, farm buildings 20%, buildings with three or more apartments 18%, garage buildings 7%, each of the other classes contains less than 4%.
The provided data include original data downloaded from geoportal.gov.pl (on 11 December 2020) [2] as well as processed data. The aggregation process was performed taking into account the proximity of the neighborhood [3] based on the minimum size of the figure [4, 5]. The data are the basis for the subsequent steps in the process of sequential generalization of building groups.

title: Development of factors and measurement of personnel risk in the marketing services of four Polish pharmaceutical companies

description: This text contains the presentation and analysis of research results in relation to four companies (A, B, C, D), according to the adopted case study method.Further considerations should be preceded by the assumption that personal risk factors often affect the level of this risk in various directions, so their final impact is the result of the shaping of individual factors.         
The ranges adopted in the study in the assessment of risk factors are, of course, arbitrary, allowing each factor to be placed on the axis of the continuum: static-dynamic configuration.

title: Topographic AFM imaging of the leaf surface with magnification of details of its morphological structure

description: Topographic imaging of the leaf surface with magnification of details of its morphological structure. Measurements in semi-contact mode. NTEGRA Prima (NT-MDT) device. NSG 01 probe.
Atomic force microscopy is a research technique involving the mechanical interaction between the surface of the test sample and the probe in the shape of a pyramidal blade. Depending on the applied force of impact, the described technique may be characterized by a different degree of destructiveness for the object subjected to imaging. In the case of particularly delicate samples, their degradation (scratches) may occur when excessive contact forces are applied. Semi-contact or non-contact techniques are used to study mechanically unstable objects such as biological samples (cells, DNA chains or tissues), minimizing the contact time between the probe and the tested surface. The presented file contains the results of scanning in one of the above variants (tapping mode) in relation to the leaf sample. Thanks to the use of the semi-contact technique, it was possible to distinguish delicate structural elements that could be damaged when trying to scan in the contact mode. The file contains 36 images.

title: Mechanical properties of VL E27 steel for shipbuilding – fracture documentation (test in +20°C)

description: One of the basic divisions of steels used for ship hulls and ocean engineering structures is the division into: normal strength steels, high strength steels and extra high strength steels. The belonging to the group is determined by the mechanical properties of the steel, such as: yield point, ultimate strength and plastic elongation after fracture. The steels in each group are divided into categories, differing in the minimum required breaking energy at a specific temperature, determined in the Charpy test. For applications on a more responsible hull structure or offshore structure, additional steel tests may be required - determination of fracture toughness. In the shipbuilding industry, it is most often CTOD (Crack Tip Opening Displacement) test.
The published data concern testing the fracture toughness of VL E27 steel for shipbuilding, with  nominal thickness of 35 mm. It is the first steel from the group of high strength steels. It is characterized by an early low carbon content, as for hull steels, which is one of the reasons for its high ductility. The average carbon content in the tested material was 0.16%. The scope of the tests carried out so far is: tensile test at + 20 ° C, 0 ° C, -20 ° C, impact test at temperatures: 20 ° C, 0 ° C, -20 ° C, -40 ° C, - 60 ° C and a fracture toughness test at temperatures of 20 ° C, 0 ° C, -20 ° C.
The dataset contains the photographic documentation of fracture, measurement of fatigue precrack length and measurement of final crack extension.

title: Dataset of non-isomorphic graphs being coloring types (K5-e,Km-e;n), 2<m<5, 1<n<R(K5-e,Km-e)

description: For K5-e and Km-e graphs, the type coloring (K5-e,Km-e;n) is such an edge coloring of the full Kn graph, which does not have the K5-e subgraph in the first color (no edge in the graph) or the Km-e subgraph in the second color (exists edge in the graph). Km-e means the full Km graph with one edge removed.The Ramsey number R(K5-e,Km-e) is the smallest natural number n such that for any edge coloring of the full Kn graph there is an isomorphic subgraph with K5-e in the first color (no edge in the graph) or isomorphic with Km-e in the second color (exists edge in the graph). Coloring types (K5-e,Km-e;n) exist for n&lt;R(K5-e,Km-e).
The dataset consists of:a) 5 files containing all non-isomorphic graphs that are coloring types (K5-e,K3-e;n) for 1&lt;n&lt;7,b) 11 files containing all non-isomorphic graphs that are coloring types (K5-e,K4-e;n) for 1&lt;n&lt;13.
All graphs have been saved in Graph6 format (https://users.cecs.anu.edu.au/~bdm/data/formats.html).The Nauty package by Brendan D. McKay was used to check the isomorphism of the graphs (http://users.cecs.anu.edu.au/~bdm/nauty/).We recommend the survey article of S. Radziszowski containing the most important results regarding Ramsey numbers: S. Radziszowski, Small Ramsey numbers, Electron. J. Comb. Dyn. Surv. 1, revision #15, DS1: Mar 3, 2017 (https://doi.org/10.37236/21).

title: EH36 steel for shipbuilding - fracture documentation for CTOD test (plate thicnkness 60mm), a0/W = 0.6

description: The basic method of ductility designation of structural steels is the Charpy impact test. The test consists of a single strike of the specimen using a Charpy pendulum. Its result is the value of work necessary to break a specimen at a test temperature. Despite its many advantages, such as its short implementation time and low costs, it has its disadvantages, in particular:
• strong influence of notch geometry on the test result, which means that impact strength cannot be considered as an unambiguous material property,
• milled notches are not repeatable because the cutter wears,
• regardless of the thickness of the material being tested, samples of the same size are used.
Due to these disadvantages, for very responsible ship and ocean engineering constructions, such as: continuous longitudinal coamings of the largest container ships, or supporting components of drilling platforms, tests are carried out basing on fracture mechanics. For shipbuilding industry, CTOD (Crack Tip Opening Displacement) is, the most often, desired value. The test CTOD is performed by slowly bending the specimen with record of the slit opening. Before performing the test, it is necessary to know the material properties (from a tensile test). The final stage of the test is the measurement of the initial fatigue fracture geometry.
The dataset contains the photographic documentation of fracture and measurement of fatigue precrack for a0/W = 0.60 specimen.

title: Simulation of perovskite-based CuI/CH3NH3PbI3/TiO2 solar cell performance

description: The presented data set is part of the theoretical research on novel thin-layer lead-halide perovskite solar cells with different inorganic transparent conductive oxides used as charge transport layers. In this study CuI/CH3NH3PbI3/TiO2 model structure (Model 1) was investigated by the use of the SCAPS-1D simulation method (https://scaps.elis.ugent.be/). 
The illumination source was assumed to be a standard solar spectrum AM 1.5G (1000 W/m2). The calculations were performed using default SCAPS generation and absorption models, and a defect-originated Shockley-Read-Hall recombination (SRH) model. The radiative band-to-band and Auger recombination mechanisms were neglected. 
The DC J-V characteristics, power conversion efficiency (PCE), fill factor (FF), open-circuit voltage (Voc), short-circuit current (Jsc) and output cell power were analyzed for selected series and shunt resistances. The temperature effect on the overall device performance was also examined.

title: Linear and nonlinear impedance of alkali and iron doped silicate-lead glasses

description: Linear and nonlinear impedance was studied for lead-silicate glass samples doped with iron ions and alkaline oxides. The compositions of glasses were as follows: (in %mol) 50% SiO2, 25% PbO, 15% Fe2O3 and 15% one of alkaline oxides: Na2O, K2O, Li2O. All samples were prepared by the conventional melt quenching technique. The substrates were powdered in a mortar and melted in alumina crucibles. The melting of glass containing lithium ions was conducted in air at 1373K. The glasses with potassium ions and sodium ions were melted at 1473K. The melts were poured out on plate heated up to 673K and formed into small circular-shaped pellets (about 1,5 mm thick and 20 mm in diameter). Next glasses were annealing at  the 673K and cooling with furnance. After a polishing, golden electrodes were evaporated at both sides of  preheated samples in vacuum, for the electrical conductivity measurements. The linear and nonlinear impedance spectra were measured in the frequency range of 1 mHz to 1 MHz and in the temperature range of 153K to 483K by Concept 40 broadband dielectric spectrometer. The nonlinear electrical properties were measured also as a function of A.C. voltage in range of 0.01 - 1 Vrms.

title: Magnetic properties of of lead-silicate glasses and nanocomposites doped with iron oxide

description: Magnetic properties of iron-doped glasses and glass-ceramics were studied. Two different sets of glass samples were prepared. The first group of samples has the composition of (50 − 0.5x)SiO2–(50 − 0.5x)PbO– xFe2O3, where x = 15 and 20 (in mol%). Composition of the second group was 50SiO2–(50−x)PbO–xFe2O3, where x=15, 20 and 25 (in mol%). All sampleswere prepared by the conventional melt quenching technique; the melting was conducted in air at 1623 K in alumina crucibles. The melts were poured on a brass plate preheated to 573 K and formed into button-shaped samples. Afterwards pellets were annealed at 673K, cooledwith the furnace and polished to the thickness of about 1mm. Magnetic properties were analyzed by magnetic force microscopy (MFM) NT-MDT Ntegra.
