title: Simulation of a linear pneumatic actuator with 100 mm piston diameter, 32 mm piston rod diameter and 200 mm stroke

description: The aim of the simulation was to determine the dynamics of linear pneumatic actuators with different sizes and flow properties. The simulation used the actuator dynamics model as described in [1] and the St Venant - Wantzel's mass flow rate model. The simulation experiment was to calculate the pressure changes in both chambers of the actuator as well as the position and velocity of the piston during the stroke. The simulation results were saved in the default GNU Octave (text) format. The original purpose of the experiments was to obtain data to create a neural model of a pneumatic actuator.[1] Kiczkowiak T.: Algorithms and Models Applied in the Design of Pneumatic Driving Systems (in Polish), Koszalin 2005, Publishing House of Koszalin University of Technology

title: Electronic transition dipole moment functions of the second singlet Sigma ungerade plus and second triplet Sigma gerade plus states of the Lithium dimer

description: Electronic transition dipole moment functions (ETDMF) of the second singlet Sigma ungerade plus (2sSu+) and second triplet Sigma gerade plus (2tSg+) states have been calculated for the Lithium dimer. ETDMFs are needed in understanding processes like photodissociation, photoassociation, cooling, and trapping of molecules. The results of the four ETDMFs have been obtained by the nonrelativistic multireference configuration interaction (MRCI) method used with pseudopotentials describing the interaction of valence electrons with atomic cores. In this approach, only the valence electrons of the Li atom were treated explicitly. The core polarization potential has been also applied in calculations. All computations were performed by means of the MOLPRO program package. In all internuclear regions, presented ETDMFs reasonably agree with available previously calculated and measured results.
The dataset is arranged in five columns. &lt;Ψ_f | DMX or DMY or DMZ | Ψ_i&gt; is the x or y or z component of the electronic dipole moment between the initial state Ψ_i and the final state Ψ_f of the diatomic Lithium molecule. The first column contains distances in Bohr radius units [a0] between Lithium atoms. The consecutive four columns contain ETDMFs calculated for corresponding distances. All values are given in atomic units. All ETDMFs are provided as functions of the internuclear distance R, ranging from 2 to 90 [a0].
The symbols used for describing the initial (Ψ_i) and final (Ψ_f) states (for example 2tPg or 4sSu+) of the Li2 molecule are the following:
1 or 2 or ... - the electronic initial or final state number;
s or t - singlet or triplet state;
S or P or D - Sigma, Pi or Delta state;
g or u - gerade or ungerade state;
+ is connected only with Sigma states.

title: The assessment of microbiological purity of cosmetic preparations

description: The dataset contains the results of a single series of determinations of the microbiological purity of the cosmetic based on the aqueous phase in the test for the total number of bacteria and the total number of yeasts.The tests were performed by preparing a series of decimal dilutions of the cosmetic in peptone water and performing in-depth culture using PCA and Sabouraud media dedicated to the propagation of bacteria and yeast, respectively.

title: Toxoplasma gondii recombinant chimeric antigens - IgG and IgM ELISAs - human serum samples

description: This study presents an evaluation of tetravalent recombinant chimeric proteins containing fragments of the Toxoplasma gondii antigens, SAG1, SAG2, GRA1, GRA2, MIC1, MAG1, ROP1 and AMA1, as potential replacements of a the soluble, whole-cell tachyzoite lysate (TLA) used in serological assays. Recombinant chimeric proteins (SAG1-MIC1-MAG1-GRA2, SAG2-GRA1-ROP1-GRA2, SAG2-GRA1-ROP1-AMA1N, AMA1N-SAG2-GRA1-ROP1, AMA1C-SAG2-GRA1-ROP1, and AMA1-SAG2-GRA1-ROP1) obtained by genetic engineering were tested for their reactivity with specific IgM and IgG antibodies from sera of experimentally infected mice and humans with T. gondii infection using an enzyme-linked immunosorbent assay (ELISA). Serum samples from patients with acquired T. gondii infection and sera from seronegative individuals were examined. The reactivity of chimeric antigens with antibodies generated during T. gondii invasion was measured and compared to the results obtained in assays based on whole-cell Toxoplasma antigen. Chimeric proteins proved effective in differentiation between T. gondii-infected and uninfected individuals (100% sensitivity and specificity in the IgG ELISAs) which shows their potential usefulness as a replacements for TLA in standardized commercial tests for the serodiagnosis of toxoplasmosis.

title: Laser scanning point clouds of a 32-meter radiotelescope located in the radioastronomical observatory in Piwnice (Poland)

description: This dataset contains laser scanning point clouds of a 32-meter RT4 radiotelescope located in the radioastronomical observatory in Piwnice in Poland. Measurements were performed on 18th May 2018 using two laser scanners: Leica P40 (shared by Leica Geosystems Poland) and Riegl VZ400 (shared by Geotronics Dystrybucja Sp. z o.o.). The cloud points from each scanner are separate sets which can be processed and analysed independently. The scanners were set up to cover the whole object with its range and, most importantly, they were stationary throughout the scanning process. To scan the entire construction, the possibility of moving the radiotelescope around its own axis was used. Eight scans were made. After each scan, the radiotelescope was rotated about 45 degrees around its vertical axis which allowed for a detailed scan of all construction elements. Moreover, we decided to scan the radiotelescope in two positions of a dish: when it was set in zenith direction and when a zenith angle was about 90 degrees. In this way, we ensured the accurate scanning of moving parts of the dish as well as its panels, which is useful during modelling. Consequently, sixteen scans were acquired for each scanner and stored in e57 (for Leica P40) and LAS (for Riegl VZ400) file format.

title: Tensile test of 1.4541 / X6CrNi18-10 / AISI 321 grade austenitic steel

description: Ship structures and their components are build mainly of steel. Hull steel is used to build the hull structure. Some structural elements, such as RSW (Refrigerated See Water) tanks, or LNG (Liquid Natural Gas) tanks - gas transported at temperatures below -162° C, are build from austenitic steels. Austenitic steels have a different microstructure and chemical composition than the ferritic (structural) ones. The consequence of this is their different corrosion and mechanical properties. Austenitic steels are said to be corrosion resistant (stainless). They are also much more plastic than structural steels. They plastic elongation at break, often exceeding 50%. High plasticity of austenitic steels is also proven in low temperatures (below -162° C) which is necessary to keep LNG gas in a liquid state.
The dataset contains a recorded tensile test for austenitic steel marked 1.4541, (X6CrNi18-10) or AISI 321. It is a steel with low carbon content. The tested specimen was cut from a part of the piping system of the ship's LNG gas tank. Test was performed in accordance to PN-EN ISO 6892-1: 2016-09 standard.

The results of the five excited states of the symmetry doublet Sigma ungerade plus have been obtained by the nonrelativistic multireference configuration interaction (MRCI) method used with pseudopotentials describing the interaction of valence electrons with atomic cores. In this approach, only the valence electron of the one Li atom was treated explicitly. The core polarization potential has been also applied in calculations. All computations were performed by means of the MOLPRO program package. Presented potentials are ready to compare with the results of other theoretical results and potential energy curves derived from experiments.
